A method, system, device and storage medium for communication protocol data conversion

Technical Field

The present application relates to the technical field of data conversion, and in particular to a method, system, electronic device and storage medium for communication protocol data conversion.

Background Art

In modern power systems, data collection and monitoring are key links to ensure stable operation of the power grid. Communication protocol data conversion is an important part of the data collection and monitoring system. Its conversion efficiency and accuracy directly affect the performance and reliability of the monitoring system. At present, the power system is mainly wired communication, including serial port and network port. The commonly used communication protocol for serial port is modbus, and the commonly used communication protocol for network port is IEC104. The data formats and transmission methods between these protocols are different, so data conversion is required to adapt to different system requirements.

At present, the method of converting modbus protocol data into IEC104 protocol data is to customize and develop a program for a specific modbus communication device to realize the conversion function of IEC104 protocol data. However, when the data point table of the modbus communication device changes, it is necessary to customize and develop the protocol conversion program again.

Therefore, how to provide an efficient and flexible communication protocol data conversion method to adapt to the data conversion needs between different protocols and improve the real-time and accuracy of data processing has become a problem that needs to be solved urgently.

Summary of the invention

The present application provides a method, system, device and storage medium for communication protocol data conversion, which can adapt to the data conversion requirements between different protocols and improve the real-time and accuracy of data processing.

In a first aspect of the present application, a method for communication protocol data conversion is provided, which is applied to a communication protocol data conversion platform, and the method comprises:

Reading a first configuration file of the serial port to obtain a command, wherein the command is used to read telemetry and telesignaling data of the target device, and reading a second configuration file of the network port to obtain a remote terminal unit address and a base address of the telemetry and telesignaling data;

Sending the commands to the target devices one by one through the serial port, and storing the telemetry and telesignaling data replied by the target devices into a preset first array;

Determine the target telemetry and telesignaling data that need to be forwarded to the monitoring background according to the second configuration file, search the target index of the target telemetry and telesignaling data in the first array, and store the target index in a preset second array;

After establishing a connection with the monitoring background, the target telemetry and telesignaling data are read from the preset first array according to the target index in the preset second array, the target telemetry and telesignaling data are packaged according to the format specified by the IEC104 protocol, and the packaged data are sent to the monitoring background according to the remote terminal unit address and the base address of the telemetry and telesignaling data.

By adopting the above technical solution, the configuration files of the serial port and the network port are read, and the telemetry and telesignaling data reading commands of the target device, as well as the remote terminal unit address and the base address of the telemetry and telesignaling data can be flexibly set. This method allows users to configure according to actual needs, which improves the flexibility of the communication protocol data conversion platform. Commands are sent to the target device through the serial port one by one, and the data replied by the device is stored in the preset array, ensuring the accuracy of data transmission. At the same time, through the preset index array, the target data that needs to be forwarded to the monitoring background can be quickly located, further ensuring the accuracy of data transmission. The target telemetry and telesignaling data are encapsulated in the format specified by the IEC104 protocol, and the encapsulated data is sent to the monitoring background according to the remote terminal unit address and the base address of the telemetry and telesignaling data. This method improves the efficiency of data encapsulation and transmission. As a mature telecontrol communication protocol, the IEC104 protocol specifies a format that can ensure the correct parsing and efficient transmission of data. This method is not only applicable to the current communication protocol data conversion platform configuration, but can also be expanded according to future needs. For example, when you need to add a new target device or modify the configuration of an existing device, you only need to update the corresponding configuration file without making a lot of changes to the communication protocol data conversion platform code. Through the use of configuration files and preset arrays, the reliance on hard coding of the communication protocol data conversion platform is reduced, and the reliability of the communication protocol data conversion platform is improved. At the same time, through the communication methods of serial ports and network ports, reliable data transmission between different devices can be ensured.

Optionally, before reading the first configuration file of the serial port, the method further includes configuring the first configuration file and the second configuration file, wherein configuring the first configuration file and the second configuration file includes:

In the first configuration file, serial port parameters, first protocol settings and command settings for communicating with the Modbus device are defined, wherein the first protocol settings include selecting a Modbus protocol type, setting a device ID and selecting a connection mode, and the command settings include setting a function code and a register address in a Modbus command for reading telemetry and telesignaling data;

The second configuration file defines network parameters and second protocol settings for communicating with the IEC104 device, wherein the second protocol settings include an address that uniquely identifies the remote terminal unit device in the IEC104 network and a starting address that defines telemetry and telesignaling data in the remote terminal unit device.

By adopting the above technical solution, through the definition of the first configuration file and the second configuration file, the communication parameters, protocol settings and data reading commands with Modbus devices and IEC104 devices are clearly managed and defined. This management method improves the readability and maintainability of the communication protocol data conversion platform. In the first configuration file, the Modbus protocol type, device ID and connection method can be flexibly selected to meet the needs of communicating with different Modbus devices. This flexibility enables the communication protocol data conversion platform to adapt to a variety of Modbus devices and enhances the versatility of the communication protocol data conversion platform. The function code and register address of the Modbus command for reading telemetry and telesignaling data are set in the first configuration file to ensure the accuracy of data reading. This precise control enables the communication protocol data conversion platform to accurately obtain the data of the target device, improving the accuracy and reliability of the data. The unique address of the remote terminal unit device in the IEC104 network is defined in the second configuration file to ensure the accuracy of the data during the sending and receiving process. At the same time, the starting address of the telemetry and telesignaling data is defined so that the communication protocol data conversion platform can accurately locate the data segment to be sent, improving the efficiency and accuracy of data transmission. Managing communication parameters and protocol settings through configuration files makes it easier to expand new devices or modify existing device configurations. You only need to update the corresponding configuration files without modifying the code of the communication protocol data conversion platform, which improves the scalability and maintainability of the communication protocol data conversion platform. Clear configuration management and precise command control reduce communication protocol data conversion platform failures and data errors caused by configuration errors or command errors. At the same time, the readability and maintainability of the configuration files also help to quickly locate and solve communication protocol data conversion platform problems.

Optionally, sending the commands to the target devices one by one through the serial port, and storing the telemetry and telesignaling data replied by the target devices into a preset first array comprises:

Reading the first configuration file, and initializing the target serial port according to the serial port parameters in the first configuration file;

Get the list of telemetry and telesignaling commands that need to be sent to the target device;

Through the initialized target serial port, the commands in the telemetry and telesignaling command list are sent to the target device one by one in a preset frame format, and the target serial port is continuously monitored;

When a reply from the target device is detected, the reply data is determined to be stored in the first position of the preset first array according to the mapping relationship in the first configuration file, and the telemetry and telesignaling data replied by the target device are stored in the preset first array according to the first position.

By adopting the above technical solution, accurate communication with the target device is ensured by reading the first configuration file and initializing the target serial port according to the serial port parameters therein. This avoids data transmission problems caused by serial port configuration errors. A list of telemetry and telesignaling commands that need to be sent to the target device is obtained, and sent one by one through the initialized target serial port, ensuring the orderly execution of the commands. This helps to avoid command conflicts or omissions and improves the accuracy and completeness of data acquisition. After sending the command, the target serial port is continuously monitored to wait for the device's reply. This real-time monitoring mechanism ensures that the communication protocol data conversion platform can process the device's response in a timely manner, improving the response speed and data processing efficiency of the communication protocol data conversion platform. According to the mapping relationship in the first configuration file, the storage location of the data replied by the target device in the preset first array is determined, and the data is stored in the location. This data mapping method ensures accurate data storage and convenience of subsequent processing. The telemetry and telesignaling data replied by the target device are stored in the preset first array, which is convenient for subsequent data processing and forwarding. This centralized storage method reduces the complexity and time cost of data processing and improves the overall data processing efficiency. By managing serial port parameters and mapping relationships through configuration files, the communication protocol data conversion platform becomes easier when expanding new devices or modifying existing device configurations. It only needs to update the corresponding configuration files without modifying the communication protocol data conversion platform code, which improves the scalability and maintainability of the communication protocol data conversion platform.

Optionally, the preset first array includes a preset first sub-array and a preset second sub-array, and storing the telemetry and telesignaling data replied by the target device into the preset first array includes:

Find a first entry that matches the device address and the register address, obtain a first index corresponding to the first entry, and store the telemetry data to a position corresponding to a preset first subarray according to the first index;

A second entry matching the device address and the status bit is searched, and a second index corresponding to the second entry is obtained, and the remote signaling data is stored in a position corresponding to a preset second sub-array according to the second index.

By adopting the above technical solution, the telemetry data is stored in the preset first sub-array, and the telesignaling data is stored in the preset second sub-array, so that the classified storage of data is realized. This classification method enables different types of data to be clearly separated, which is convenient for subsequent data processing and analysis. According to the device address, register address and status bit, index matching can be performed to quickly locate the position of the target data in the preset sub-array. This index matching method reduces the time of data retrieval and improves the efficiency of data processing. Since the data has been stored in the corresponding sub-array according to the type, when processing the data, it is only necessary to operate on a specific sub-array, which reduces the complexity of data processing. This helps to reduce the error rate of the communication protocol data conversion platform and improve the accuracy of data processing. The classified storage and index matching method of data makes data management and maintenance easier. When it is necessary to modify or expand the data, it is only necessary to operate on a specific sub-array without reconstructing or modifying the entire array. The design of this data structure enables the communication protocol data conversion platform to be easily expanded to support more devices and data types. The integration of new devices and data types can be achieved by simply adding corresponding sub-arrays and index matching rules. The accuracy and consistency of the data can be ensured through clear index matching rules and data storage structure. This helps reduce errors and losses during data transmission and improves the reliability and stability of the communication protocol data conversion platform.

Optionally, determining the target telemetry and telesignaling data to be forwarded to the monitoring background according to the second configuration file, searching the first array for a target index of the target telemetry and telesignaling data, and storing the target index in a preset second array comprises:

Extracting identification information of target telemetry and telesignaling data that needs to be forwarded to the monitoring background, and storing the identification information in a preset data structure;

Traversing the preset first array, and for each data item in the preset first array, checking whether it can match the identification information in the preset data structure;

The subscripts of the data items that can match the identification information in the preset data structure in the preset first array are mapped to the preset second array.

By adopting the above technical solution, the identification information of the target telemetry and telesignaling data that needs to be forwarded to the monitoring background in the second configuration file is extracted, and the communication protocol data conversion platform can clearly know the data that needs to be forwarded, avoiding unnecessary data transmission and improving the efficiency of data forwarding. By traversing the preset first array and checking whether each data item therein can match the identification information in the preset data structure, the communication protocol data conversion platform can quickly find the target data that needs to be forwarded. This efficient data matching mechanism reduces the data processing time and improves the real-time performance of data forwarding. The subscripts of the data items that can match the identification information in the first array are mapped to the preset second array, which provides convenience for subsequent data forwarding. Through index mapping, the communication protocol data conversion platform can directly read the target data from the preset first array without having to traverse and match again, further improving the efficiency of data forwarding. The data that needs to be forwarded and its identification information are managed by the configuration file and the preset data structure, making the communication protocol data conversion platform simpler when maintaining and expanding. When it is necessary to modify or increase the data that needs to be forwarded, it is only necessary to update the configuration file or the preset data structure without modifying the communication protocol data conversion platform code. Since the communication protocol data conversion platform only forwards the required data instead of sending the entire first array of data to the monitoring background, the amount of data transmission is reduced and the network bandwidth usage is reduced. This is especially important in an environment with limited network resources. Through clear data forwarding requirements and an efficient data matching mechanism, the communication protocol data conversion platform can ensure that the forwarded data is accurate and complete. This helps to improve the reliability and stability of the communication protocol data conversion platform and reduce communication protocol data conversion platform problems caused by data transmission errors.

Optionally, the preset second array includes a preset third subarray and a preset fourth subarray, and mapping the subscripts of the data items that can match the identification information in the preset data structure in the preset first array to the preset second array includes:

For each target telemetry data item that can match the identification information in the preset data structure, obtain the third index of the target telemetry data item in the preset first sub-array, and store the third index in the preset third sub-array;

For each target telesignaling data item that can match the identification information in the preset data structure, a fourth index of the target telesignaling data item in the preset second subarray is obtained, and the fourth index is stored in the preset fourth subarray.

By adopting the above technical solution, the index of the target telemetry data item is stored in the preset third sub-array, and the index of the target telesignal data item is stored in the preset fourth sub-array, so as to realize the classified storage of data. This classification method enables different types of data to be clearly separated, which is convenient for subsequent data processing and analysis. Since the data has been stored in the corresponding sub-array according to the type, when processing the data, the communication protocol data conversion platform only needs to pay attention to the index in the specific sub-array without traversing the entire array. This targeted processing method significantly improves the data processing efficiency. The classified storage and index mapping method reduces the complexity of the communication protocol data conversion platform. The communication protocol data conversion platform does not need to process mixed data, but only needs to operate on specific types of data, which reduces the complexity and error rate of the communication protocol data conversion platform. The classified storage and index mapping method of data makes data management and maintenance easier. The communication protocol data conversion platform can easily add, modify or delete specific types of data without adjusting the entire communication protocol data conversion platform. When the communication protocol data conversion platform needs to support more data types or devices, it only needs to add corresponding sub-arrays and index mapping rules. This design makes the communication protocol data conversion platform highly scalable and adaptable to changing needs. Since the data is organized by type and index, when sending data to the monitoring background, the communication protocol data conversion platform can directly read the data from the corresponding sub-array according to the index without additional data processing or conversion. This helps to optimize the data transmission process and reduce the network bandwidth usage.

Optionally, encapsulating the target telemetry and telesignaling data in a format specified by the IEC104 protocol, and sending the encapsulated data to the monitoring background according to the remote terminal unit address and the base address of the telemetry and telesignaling data includes:

According to the provisions of the IEC104 protocol, an application service data unit is created, and the target telemetry and telesignaling data are embedded into the application service data unit;

Calculating and setting a checksum or cyclic redundancy check value of the application service data unit according to the IEC104 protocol to encapsulate data of the application service data unit;

The encapsulated data of the application service data unit is sent to the monitoring background using the established network connection.

By adopting the above technical solution, an application service data unit (ASDU) is created and the target telemetry and telesignaling data are embedded in it, ensuring the standardization of data encapsulation. This standardized encapsulation enables data to be compatible and interoperable between different systems, improving the versatility and reliability of the system. The checksum or cyclic redundancy check value (CRC) of the application service data unit is calculated and set according to the IEC104 protocol, which can effectively detect errors in the data transmission process and ensure the integrity and accuracy of the data. This verification mechanism is essential to ensure the stable operation of the power system monitoring and data acquisition system. The encapsulated application service data unit is sent to the monitoring background using the established network connection, realizing efficient data transmission. This transmission method reduces the delay of data transmission and ensures that the monitoring system can obtain the operating status and data of the power equipment in real time, so as to respond in time. Sending data to the monitoring background through the IEC104 protocol enables the background to remotely monitor and control the equipment in the power system. This remote monitoring and control capability improves the management efficiency and response speed of the power system and reduces the operation and maintenance costs. As an international standard communication protocol, the IEC104 protocol has good scalability and compatibility. This means that the communication protocol data conversion platform can be easily integrated with other devices or systems using the same protocol, thereby achieving a wider range of monitoring and control.

In a second aspect of the present application, a system for communication protocol data conversion is provided, including a reading module, a storage module, an indexing module and an execution module, wherein:

This embodiment discloses a method for communication protocol data conversion, which is applied to a communication protocol data conversion platform. FIG1 is a flow chart of the method for communication protocol data conversion disclosed in the embodiment of the present application. As shown in FIG1 , the method includes steps S110-S140.

S110, reading a first configuration file of the serial port to obtain a command, wherein the command is used to read telemetry and telecommunication data of the target device, and reading a second configuration file of the network port to obtain a remote terminal unit address and a base address of the telemetry and telecommunication data;

Figure 2 is a schematic diagram of the device connection topology disclosed in the embodiment of the present application. As shown in Figure 2, the modbus protocol is converted into the IEC104 protocol through the serial port configuration file and the network port configuration file. The embodiment of the present application is explained in conjunction with Figure 2.

Extract the commands for reading the telemetry and telesignaling data of the target device from the first configuration file. These commands may be predefined strings or templates that need further processing. The second configuration file may contain information such as network settings, device addresses, data addresses, etc. It is necessary to find the part containing the RTU (remote terminal unit) address and the base address of the telemetry and telesignaling data. Extract the RTU address and the base address of the telemetry and telesignaling data from the configuration file. This information may be an IP address, port number, or memory address, etc.

Optionally, before reading the first configuration file of the serial port, the method further includes configuring the first configuration file and the second configuration file, wherein configuring the first configuration file and the second configuration file includes:

In the first configuration file, serial port parameters, first protocol settings and command settings for communicating with the Modbus device are defined, wherein the first protocol settings include selecting a Modbus protocol type, setting a device ID and selecting a connection mode, and the command settings include setting a function code and a register address in a Modbus command for reading telemetry and telesignaling data;

The second configuration file defines network parameters and second protocol settings for communicating with the IEC104 device, wherein the second protocol settings include an address that uniquely identifies the remote terminal unit device in the IEC104 network and a starting address that defines telemetry and telesignaling data in the remote terminal unit device.

The first configuration file is mainly used to define the parameters and commands for communicating with Modbus devices. Modbus is a serial communication protocol commonly used in industrial automation systems. Serial port parameters include serial port number, baud rate, data bit, stop bit, and parity bit. The first protocol setting includes selecting the Modbus protocol type, setting the device ID, and selecting the connection method. There are two main types of Modbus protocols - Modbus RTU and Modbus TCP. Here you need to specify the type to use. If you are using Modbus RTU, you also need to specify whether it is polling or listening mode. Each Modbus device has a unique device ID to identify itself in communication. The Modbus protocol uses function codes to define different operations. For example, reading the coil status (telemetering data) usually uses function code 01, while reading the holding register (telemetry data) usually uses function code 03. For each telemetry or telemetering data that needs to be read, you need to specify its register address in the Modbus device.

The second configuration file is mainly used to define the network parameters and protocol settings for communicating with IEC104 devices. IEC104 is a power system communication protocol used for remote monitoring and control. Network parameters include IP address, port number, and other possible network settings such as gateway, subnet mask, etc. The second protocol settings include the remote terminal unit (RTU) address, and the starting address of telemetry and telesignaling data. The remote terminal unit (RTU) address is the address used to uniquely identify the RTU device in the IEC104 network, and the starting address of telemetry and telesignaling data is used to define the starting position of telemetry and telesignaling data in the RTU device. These data are usually encoded and organized in accordance with the provisions of the IEC104 protocol.

Through the configuration file, users can flexibly set the relevant parameters for communication with Modbus devices and IEC104 devices. Whether it is serial port parameters, network parameters or protocol settings, they can be adjusted according to the specific device and network environment. The first configuration file supports the setting of Modbus protocol. Users can select the Modbus protocol type, set the device ID and select the connection method. This compatibility enables the platform to communicate with a variety of Modbus devices. The second configuration file supports the setting of IEC104 protocol. Users can define the address that uniquely identifies the remote terminal unit device in the IEC104 network and the starting address of telemetry and telesignaling data. This ensures that the platform can exchange data with IEC104 devices. The configuration file method allows users to complete the parameter and protocol settings by editing the corresponding configuration file without modifying the code or making complex settings. This greatly reduces the difficulty of use and improves ease of use. Through the configuration file method, new device and protocol support can be easily added. Just define a new configuration file and add the corresponding parsing and processing logic in the platform. This scalability enables the platform to adapt to more device and protocol requirements in the future. Through clear configuration, it can be ensured that the platform uses the correct parameter and protocol settings when communicating with the device. This helps reduce errors and losses in data transmission and improves data accuracy.

S120, sending the commands to the target devices one by one through the serial port, and storing the telemetry and telesignaling data replied by the target devices into a preset first array;

Initialize the serial port connected to the target device, which includes setting the communication parameters of the serial port, such as baud rate, data bit, stop bit and check bit, to ensure that the communication parameters are consistent with those of the target device. Read the commands for reading the telemetry and telesignaling data of the target device from the previously configured first configuration file. These commands are usually based on a specific communication protocol (such as Modbus) and contain information such as device address, function code, register address, etc. Send the parsed commands to the target device one by one through the initialized serial port connection. When sending commands, it is necessary to ensure that the format and encoding of the commands are consistent with the communication protocol of the target device. After sending the command, the platform needs to wait for the target device to reply. After receiving the command, the target device will perform the corresponding operation according to the content of the command and reply the result to the platform through the serial port. When the platform receives the reply from the target device, it needs to parse the reply data. The parsing process usually includes verifying the integrity and correctness of the data (such as CRC check), and then extracting the telemetry and telesignaling data. After parsing the telemetry and telesignaling data, these data need to be stored in the preset first array. The preset first array is a data structure used to store and process data within the platform. It is usually a dynamic array or list, and the capacity can be expanded as needed. When storing data, it can be classified and stored according to the type and importance of the data for subsequent data processing and forwarding. At the same time, metadata information such as timestamps can be added to each data item to facilitate data tracking and troubleshooting. Throughout the process, error handling mechanisms also need to be considered. If errors occur in serial communication (such as connection interruption, data loss, etc.), the platform needs to be able to identify and handle these errors, such as reconnecting the serial port, reissuing commands, etc. If the platform needs to communicate with multiple target devices at the same time, thread synchronization and concurrent processing issues also need to be considered. Concurrent processing can be achieved through multi-threading or asynchronous programming technology to improve the processing power and response speed of the platform.

Optionally, sending the commands to the target devices one by one through the serial port, and storing the telemetry and telesignaling data replied by the target devices into a preset first array comprises:

Reading the first configuration file, and initializing the target serial port according to the serial port parameters in the first configuration file;

Get the list of telemetry and telesignaling commands that need to be sent to the target device;

Through the initialized target serial port, the commands in the telemetry and telesignaling command list are sent to the target device one by one in a preset frame format, and the target serial port is continuously monitored;

When a reply from the target device is detected, the reply data is determined to be stored in the first position of the preset first array according to the mapping relationship in the first configuration file, and the telemetry and telesignaling data replied by the target device are stored in the preset first array according to the first position.

The first configuration file is loaded from a predetermined file path. The first configuration file contains the serial port parameters required for communication with the Modbus device. The platform parses the serial port parameters in the configuration file. These parameters usually include the serial port number, baud rate, data bit, stop bit, check bit, etc. Using the parsed serial port parameters, the platform initializes the target serial port and establishes a communication connection with the target device. The platform reads the command settings related to telemetry and telesignaling data reading from the first configuration file. These settings usually include Modbus function code, device address, register address, etc. According to the command settings read, the platform constructs a telemetry and telesignaling command list to be sent to the target device. Each command contains complete Modbus request frame information. The platform sends the commands in the telemetry and telesignaling command list to the target device one by one in a preset frame format (such as Modbus RTU or Modbus TCP frame format) through the initialized target serial port. After sending the command, the platform continues to listen to the target serial port and waits for a reply from the target device. When the platform detects a reply from the target device, it starts processing the reply data. The platform first verifies the integrity and correctness of the reply data (such as CRC check), and then parses out the telemetry and telesignaling data therein. Based on the mapping relationship in the first configuration file (which is usually predefined, corresponding to the specific data replied by the device with the position in the first array), the platform determines the location where these data are stored in the preset first array. The platform stores the parsed telemetry and telesignaling data in the preset first array according to the determined location. If the platform does not receive a reply from the target device within a period of time after sending a command, it should be able to handle this situation, such as by resending the command or recording an error log. If the platform needs to communicate with multiple target devices at the same time, appropriate concurrency techniques (such as multithreading or asynchronous I/O) should be used to avoid blocking and improve efficiency. Pay special attention to data consistency when processing data, and ensure that the data stored in the first array is consistent with the original reply data, and there are no omissions or errors. Throughout the process, the platform should be able to identify and handle various error situations, such as serial port communication errors, configuration file errors, parsing errors, etc., and give corresponding error prompts or log records.

By reading the first configuration file and initializing the target serial port, the communication parameters with the target device are accurately set, thereby ensuring the reliability and stability of communication. The commands in the telemetry and telesignaling command list are sent one by one, reducing the confusion or conflict of commands that may be caused by concurrent sending. At the same time, the target serial port is continuously monitored to ensure that the reply of the target device is captured at the first time. According to the mapping relationship in the first configuration file, the location where the data replied by the target device is stored in the preset first array can be accurately determined. This accuracy ensures the accuracy of subsequent data processing and forwarding. Defining communication parameters and commands through configuration files makes the system easier to expand and maintain. When it is necessary to add new devices or adjust communication parameters, only the configuration file needs to be modified without modifying the program code. Continuous serial port monitoring and precise data storage mechanism enable the system to better cope with various abnormal situations, such as device failure, communication interruption, etc. Even in this case, the system can accurately record and process data, ensuring the integrity and accuracy of the data. By directly storing the data replied by the target device in the preset array, the complexity of multiple data processing and conversion is avoided. This not only improves the speed of data processing, but also reduces the errors that may be introduced by data conversion.

Optionally, the preset first array includes a preset first sub-array and a preset second sub-array, and storing the telemetry and telesignaling data replied by the target device into the preset first array includes:

Find a first entry that matches the device address and the register address, obtain a first index corresponding to the first entry, and store the telemetry data to a position corresponding to a preset first subarray according to the first index;

A second entry matching the device address and the status bit is searched, and a second index corresponding to the second entry is obtained, and the remote signaling data is stored in a position corresponding to a preset second sub-array according to the second index.

Two array storage spaces are opened for modbus data collection, cjyc[1024] (i.e., the preset first subarray) and cjyx[1024] (i.e., the preset second subarray). Before starting to store data, the preset first array (including the first subarray and the second subarray) needs to be initialized. This usually means allocating appropriate memory space for the array and setting initial values (such as zero or null values). When a reply is received from the target device, the reply data needs to be parsed. This usually involves decoding the communication frame and extracting information such as the device address, register address, data value, and possible status bits. Traverse the entries in the preset index mapping table or configuration file to find the first entry that matches the received device address and register address. The first entry should contain information for locating the location of the telemetry data storage in the preset first subarray. When a matching first entry is found, the first index corresponding to the first entry is obtained. According to the obtained first index, the parsed telemetry data is stored in the location corresponding to the preset first subarray. Similarly, traverse the entries in the preset index mapping table or configuration file to find the second entry that matches the received device address and status bit. The second entry should contain information for locating the storage location of the telesignal data in the preset second subarray. When a matching second entry is found, the second index corresponding to the second entry is obtained. According to the obtained second index, the parsed telesignal data is stored in the location corresponding to the preset second subarray. The index mapping table or configuration file is the key to ensure that the data can be accurately stored in the subarray. Therefore, it is necessary to ensure that these mapping tables or configuration files are up-to-date and accurate. When the device address, register address or status bit changes, these mapping tables or configuration files should be updated in a timely manner. If any problems are encountered during the storage process (such as index out of bounds, data format error, etc.), appropriate error handling mechanisms should be implemented and detailed log files should be recorded for subsequent analysis and debugging. Ensuring the accuracy of the index mapping table or configuration file is critical to avoiding data misalignment and confusion. When processing large amounts of data, performance optimization may need to be considered, such as using hash tables or other efficient data structures to speed up the index lookup process. If the target device's reply contains multiple data items, they may need to be parsed and stored in a specific order or priority.

By storing telemetry data and telesignaling data in the preset first subarray and the preset second subarray respectively, orderly storage of data is achieved. This classified storage method makes subsequent data processing and query more efficient because the corresponding subarray can be directly located for operation. According to the device address and register address or status bit matching entries, and obtaining the corresponding index, the location where the data should be stored in the preset first subarray and the preset second subarray can be accurately located. This precise index positioning avoids misplacement or overwriting of data and ensures the integrity and accuracy of the data. Since telemetry and telesignaling data are stored in different subarrays respectively, and each data item has a clear index position, it is convenient to query and process data according to the index. This is very useful for scenarios that require real-time analysis or statistics of telemetry and telesignaling data. When a new target device or data type needs to be added, just add the corresponding entry in the configuration file and adjust the structure of the preset first array. This scalability enables the system to adapt to changing needs and maintain long-term stability and reliability.

S130, determining the target telemetry and telesignaling data that needs to be forwarded to the monitoring background according to the second configuration file, searching the target index of the target telemetry and telesignaling data in the first array, and storing the target index in a preset second array;

The second configuration file is read. The second configuration file may contain multiple rules or conditions for determining the telemetry and telesignaling data that needs to be forwarded to the monitoring background. These rules may be based on various factors such as data type, range, timestamp, device ID, etc. The communication protocol data conversion platform then parses the forwarding rules in the second configuration file. These rules may exist in different forms, such as regular expressions, logical expressions, range conditions, etc. The communication protocol data conversion platform needs to understand and apply these rules to filter out the data that needs to be forwarded. After determining the forwarding rules, the communication protocol data conversion platform begins to traverse the preset first array. This array stores all telemetry and telesignaling data received from the target device. The communication protocol data conversion platform needs to traverse this array and check whether each data item meets the forwarding rules. In the process of traversing the first array, the communication protocol data conversion platform will check each data item to see if it meets the conditions defined in the forwarding rules. If the data item meets a forwarding rule, it is considered to be the target telemetry or telesignaling data that needs to be forwarded to the monitoring background. When a data item is determined to be the target data that needs to be forwarded, the communication protocol data conversion platform needs to find the index position of the data item in the first array. This index position is the target index, which is used to identify the specific position of the data item in the array. When the communication protocol data conversion platform finds the target index of the target data, it will store this index in the preset second array. This second array is used to record the index positions of all data items that need to be forwarded to the monitoring background in the first array. The communication protocol data conversion platform can use the preset index position in the second array to extract the data to be forwarded from the first array and send it to the monitoring background. This process may involve multiple steps such as network communication, data encoding and decoding.

Optionally, determining the target telemetry and telesignaling data to be forwarded to the monitoring background according to the second configuration file, searching the first array for a target index of the target telemetry and telesignaling data, and storing the target index in a preset second array comprises:

Extracting identification information of target telemetry and telesignaling data that needs to be forwarded to the monitoring background, and storing the identification information in a preset data structure;

Traversing the preset first array, and for each data item in the preset first array, checking whether it can match the identification information in the preset data structure;

The subscripts of the data items that can match the identification information in the preset data structure in the preset first array are mapped to the preset second array.

According to the second configuration file, the identification information of the target telemetry and telesignaling data to be forwarded to the monitoring background is extracted. This identification information may be attributes that can uniquely identify the data item, such as device ID, data type, data tag, etc. The extracted identification information will be stored in a preset data structure for subsequent matching and search. This preset data structure can be a list, dictionary, or other type of data structure, and its design should be able to efficiently store and retrieve identification information. For example, if the identification information contains the device ID and data type, a dictionary (such as Python's dict in a programming language) can be used to store this information, where the device ID is used as the key, the data type is used as the value, or another data structure related to it (such as a list). The platform begins to traverse the preset first array. The first array stores all telemetry and telesignaling data received from the target device, and each data item contains one or more identification information. In the process of traversing the first array, the platform checks each data item to determine whether it contains the identification information in the preset data structure. This usually involves comparing the identification information in the data item with the key or value in the preset data structure. If the identification information in the data item matches an entry in the preset data structure, then the data item is regarded as the target data that needs to be forwarded. For each data item that matches the identification information, the platform needs to find its subscript (index position) in the first array. This subscript identifies the specific position of the data item in the array and is required for subsequent data extraction and forwarding. The platform will map this subscript to the preset second array. The mapping process can be to add the subscript directly to the second array as an element, or to encapsulate the subscript together with other information of the data item (such as data type, timestamp, etc.) into a new data structure, and then add this new structure to the second array. Throughout the process, the platform also needs to perform verification and error handling. For example, if the identification information of a data item cannot match any entry in the preset data structure, the platform may need to record an error or warning for subsequent analysis and troubleshooting. Similarly, if the second array is full or cannot store new subscript information, the platform also needs to take appropriate error handling measures.

By extracting the identification information of the target telemetry and telesignaling data to be forwarded defined in the second configuration file and storing it in a preset data structure, the communication protocol data conversion platform can quickly identify the target data to be forwarded. This matching method based on identification information is more efficient than traversing the entire data set for conditional judgment. When traversing the preset first array, the communication protocol data conversion platform determines whether it is a target data item by checking whether each data item can match the identification information in the preset data structure. When it is confirmed to be a target data item, the communication protocol data conversion platform will map it to the preset second array in the subscript (index). This index mapping method can ensure that the data to be forwarded can be extracted from the preset first array quickly and accurately in the future. By mapping the subscript of the target data item to the preset second array, the communication protocol data conversion platform can optimize the process of data forwarding. When it is necessary to forward data, the communication protocol data conversion platform only needs to traverse the preset second array and extract the corresponding data item from the preset first array according to the index therein for forwarding without traversing the entire preset first array again. This greatly improves the efficiency and speed of data forwarding. The second configuration file allows users to define forwarding rules as needed and extract corresponding identification information. This flexible rule configuration method enables the system to adapt to different business scenarios and changes in demand. You only need to modify the configuration file to modify and expand the forwarding rules. The entire process is based on preset data structures and arrays, making the system easy to maintain and expand. If you need to add new forwarding rules or modify existing rules, you only need to modify the second configuration file without modifying the system code. At the same time, the design of preset data structures and arrays also makes the system scalable and can easily support larger-scale data processing needs.

Optionally, the preset second array includes a preset third subarray and a preset fourth subarray, and mapping the subscripts of the data items that can match the identification information in the preset data structure in the preset first array to the preset second array includes:

For each target telemetry data item that can match the identification information in the preset data structure, obtain the third index of the target telemetry data item in the preset first sub-array, and store the third index in the preset third sub-array;

For each target telesignaling data item that can match the identification information in the preset data structure, a fourth index of the target telesignaling data item in the preset second subarray is obtained, and the fourth index is stored in the preset fourth subarray.

Two array spaces are opened for IEC104 forwarding data, zfyc[1024] (i.e., the preset third subarray) and zfyx[1024] (i.e., the preset fourth subarray). According to the rules in the second configuration file, the identification information of the target telemetry and telesignaling data to be forwarded to the monitoring background is extracted. These identification information may include device ID, data type, register address, etc., which are used to uniquely identify a specific telemetry or telesignaling data item. These identification information are stored in a preset data structure for subsequent matching operations. The platform starts to traverse the preset first array. Since the preset first array contains the preset first subarray (for storing telemetry data) and the preset second subarray (for storing telesignaling data), the platform needs to traverse these two subarrays separately. When traversing the preset first subarray (telemetry data), the platform checks whether each data item can match the identification information in the preset data structure. This is usually achieved by comparing the key fields in the data item (such as device ID, data type, register address, etc.) with the corresponding fields in the identification information. If a data item matches the identification information, it is considered to be the target telemetry data item that needs to be forwarded. For each matched target telemetry data item, the communication protocol data conversion platform obtains its subscript (i.e., the third index) in the preset first subarray. This subscript is used to identify the position of the data item in the preset first subarray. Then, the communication protocol data conversion platform stores this third index in the preset third subarray. The preset third subarray is specifically used to store the index of the target telemetry data item. Similarly, when traversing the preset second subarray (telesignaling data), the communication protocol data conversion platform also checks whether each data item can match the identification information in the preset data structure. If a data item matches the identification information, it is considered to be a target telesignaling data item that needs to be forwarded. For each matched target telesignaling data item, the communication protocol data conversion platform obtains its subscript (i.e., the fourth index) in the preset second subarray. This subscript is used to identify the position of the data item in the preset second subarray. Then, the communication protocol data conversion platform stores this fourth index in the preset fourth subarray. The preset fourth subarray is specifically used to store the index of the target telesignaling data item. Through the above steps, the communication protocol data conversion platform completes the process of mapping the index of the data item that can match the identification information in the preset data structure in the preset first array to the preset second array (specifically the preset third subarray and the preset fourth subarray). In this way, in the subsequent data forwarding operation, the communication protocol data conversion platform can quickly locate the data item to be forwarded and perform corresponding processing based on the index in the preset second array.

By storing the indexes of the target telemetry data items and the target telesignaling data items in the preset third subarray and the preset fourth subarray respectively, the communication protocol data conversion platform realizes the clear classification and management of these two types of data. This classification method makes the data clearer and more orderly in subsequent processing, and reduces the risk of errors caused by confusion of data types. Since the target telemetry data items and the target telesignaling data items are stored in different subarrays respectively, the communication protocol data conversion platform can directly operate on the corresponding subarray when processing data without traversing the entire preset second array. This targeted processing method can significantly improve the efficiency of data processing, especially when processing large-scale data sets. Storing different types of data indexes separately enables the communication protocol data conversion platform to monitor and debug various types of data more conveniently. For example, when an exception or error occurs in the communication protocol data conversion platform, developers can quickly locate the data type where the problem is located and conduct targeted troubleshooting and repair. As business needs change, it may be necessary to add new data types or modify the processing logic of existing data types. By storing different types of data indexes separately, the communication protocol data conversion platform can respond to these changes more flexibly. Developers only need to add or modify index information in the corresponding sub-arrays without making large-scale modifications to the entire communication protocol data conversion platform, thereby reducing maintenance costs. Due to clear data classification and clear processing flow, the overall stability of the communication protocol data conversion platform is enhanced. Even in the face of challenges such as high concurrency and large data volumes, the communication protocol data conversion platform can maintain a stable operating state to ensure real-time and accurate forwarding of data.

S140. After establishing a connection with the monitoring background, the target telemetry and telesignaling data are read from the preset first array according to the target index in the preset second array, the target telemetry and telesignaling data are packaged according to the format specified by the IEC104 protocol, and the packaged data are sent to the monitoring background according to the remote terminal unit address and the base address of the telemetry and telesignaling data.

Refer to the target index in the preset second array. The target index corresponds to the location of the target telemetry and telesignaling data to be forwarded in the preset first array. The communication protocol data conversion platform will accurately read the target telemetry and telesignaling data from the preset first array according to these indexes. Since the precise positioning has been carried out through the index, this step can be completed efficiently and accurately. The read target telemetry and telesignaling data need to be encapsulated in the format specified by the IEC104 protocol. The IEC104 protocol, also known as the telecontrol communication protocol, defines the standard format for communication between the remote terminal unit (RTU) and the master station in the automation of the power communication protocol data conversion platform. The encapsulation process includes converting the data into the frame structure specified by the protocol, adding necessary control information and checksums, etc. to ensure the integrity and accuracy of the data. After the encapsulation is completed, the communication protocol data conversion platform will determine the data sending target based on the remote terminal unit address (RTU address) and the base address of the telemetry and telesignaling data. The RTU address is used to identify a specific remote terminal unit, and the base address of the data is used to locate the storage location of the data in the monitoring background. Through these address information, the communication protocol data conversion platform can accurately send the encapsulated data to the specified location of the monitoring background. This step ensures the targeting and accuracy of data during transmission. The above process realizes efficient and accurate data transmission from the remote terminal unit to the monitoring background. Through the preset index and address mapping mechanism, the communication protocol data conversion platform can quickly locate and read the data to be forwarded, and encapsulate and send it in the format specified by the IEC104 protocol. This processing method not only improves the efficiency of data transmission, but also ensures the integrity and accuracy of the data. At the same time, due to the use of standardized communication protocols, the communication protocol data conversion platform can seamlessly connect with other devices that follow the same protocol, enhancing the compatibility and scalability of the communication protocol data conversion platform.

Optionally, encapsulating the target telemetry and telesignaling data in a format specified by the IEC104 protocol, and sending the encapsulated data to the monitoring background according to the remote terminal unit address and the base address of the telemetry and telesignaling data includes:

According to the provisions of the IEC104 protocol, an application service data unit is created, and the target telemetry and telesignaling data are embedded into the application service data unit;

Calculating and setting a checksum or cyclic redundancy check value of the application service data unit according to the IEC104 protocol to encapsulate data of the application service data unit;

The encapsulated data of the application service data unit is sent to the monitoring background using the established network connection.

The IEC104 protocol defines multiple types of application service data units (ASDUs), each of which is used to transmit different types of information. The system needs to select the appropriate ASDU type based on the type and characteristics of the target telemetry and telesignaling data. The system creates the selected type of ASDU and embeds the target telemetry and telesignaling data into the ASDU. This usually involves arranging and encoding the data according to the format requirements of the ASDU to ensure that the data can be correctly parsed by the monitoring background. In order to ensure the reliability of data transmission, the IEC104 protocol requires that a checksum or cyclic redundancy check (CRC) value be included in each ASDU. These values are used to detect whether errors occur during data transmission. The system calculates the checksum or CRC value of the ASDU using an appropriate algorithm (such as CRC-16 or CRC-32) according to the provisions of the IEC104 protocol. This calculation process usually involves performing specific bit operations on the entire ASDU (or a part of it) and generating a fixed-length check code. The calculated checksum or CRC value is added to the corresponding field of the ASDU to complete the encapsulation of the data unit. In this way, when the monitoring background receives the data, it can verify the integrity of the data by recalculating the checksum or CRC value. Once the ASDU is encapsulated, the system can send it to the monitoring background through the established network connection. This usually involves converting the data unit into a format suitable for network transmission (such as TCP/IP data packets) and sending it through the network protocol stack. During the transmission process, the system may need to handle some network layer details, such as data packet fragmentation, retransmission, flow control, etc. These processing processes depend on the network protocol and communication environment used. After receiving the data packet, the monitoring background will parse and verify it in accordance with the provisions of the IEC104 protocol. If the ASDU checksum or CRC value in the data packet is correct and the data content meets the protocol requirements, the monitoring background will further process the data, such as updating the display interface, triggering an alarm, etc.

By encapsulating and sending data in accordance with the IEC104 protocol, the standardization and compatibility of data transmission can be ensured. This means that different systems using the same protocol can exchange data without obstacles, improving the flexibility and scalability of the system. The use of checksum or CRC values enhances the reliability of data transmission. Even in an unstable network environment or in the presence of interference, as long as the checksum or CRC value is correct, it can be assumed that no error occurred during the data transmission process, thereby ensuring the accuracy and integrity of the data. The efficiency of the encapsulation and sending process is crucial for application scenarios such as real-time monitoring and remote control. By optimizing the data transmission process and protocol implementation method, the delay and packet loss rate of data transmission can be significantly reduced, and the response speed and stability of the system can be improved.

The embodiment of the present application makes the conversion process of the communication protocol more flexible and customizable by introducing the configuration file. Developers can define different protocol conversion rules by editing the configuration file without rewriting the code, thereby greatly reducing the development time and workload. Once the configuration file is completed, the subsequent maintenance and expansion work becomes relatively simple. Only the rules in the configuration file need to be modified without modifying the entire system. This makes it easier to upgrade and improve the system, and also reduces the maintenance cost.
