Data transmission method in Internet of Things system, Internet of Things system and corresponding device

technical field

The invention relates to the technical field of the Internet of Things, in particular to a data transmission method in the Internet of Things system, the Internet of Things system and corresponding devices.

Background technique

The Internet of Things application system based on the Internet of Things service platform needs a remote transmission device (or communication module) to realize the interconnection between the short-range communication network and the long-range communication network. The following will be oriented to the Internet of Things service platform and support remote transmission The terminals are collectively referred to as M2M (machine-to-machine, machine-to-machine) gateways. The M2M gateway is a bridge for the interaction between industrial sensing devices and the Internet of Things service platform. Its role is to translate and convert data using different transmission protocols in two network segments (short-range communication network and long-distance communication network). The M2M gateway is an uplink and downlink channel that carries business functions such as information reporting, parameter configuration, and industry sensor device status detection. At present, many industry sensor devices need to use the M2M gateway to realize remote access to the IoT service platform.

Combined with the operating principle of the IoT service platform, currently IoT application developers need to develop in two aspects when accessing the IoT service platform: one is to use industrial sensing devices on the terminal side to directly connect with the M2M gateway that supports the M2M standard protocol , the M2M terminal implemented in this way can immediately realize the access to the Internet of Things service platform, and use the advantages of the Internet of Things service platform (with the authorization to access the operator's BOSS system) to expand some information related to the communication status and quality inspection of the M2M terminal. Relatively mature and reliable additional services, so as to realize all-round control and management of M2M terminals (and their SIM cards); the second is to analyze the M2M standard protocol (M2M-A protocol) on the application side and restore it to the initial data of industry sensor equipment.

However, at present, on the terminal side, there are many manufacturers of industrial sensing equipment for each monitoring object, so the communication protocols and interface methods are different, and the monitoring function requirements in specific projects are also different. The function completed by the traditional M2M terminal is to customize the analysis between the two network segment protocols according to the system integration requirements of each specific project. This kind of M2M terminal based on customized research and development has poor versatility, heavy transplant workload, and repeated development. high cost. Another is to use a custom adapter between the sensing device and the remote transmission device to support the remote communication function of the industrial sensing device, but this adapter can only support some industrial sensing devices, which has poor versatility and will be limited in application promotion. , and increases adapter cost and development time.

On the application side, because the M2M standard protocol has rich functions, many interfaces, and is difficult to understand, the requirements for IoT application developers are very high and the development workload is high. At present, when developing application-side programs based on the IoT service platform, IoT application developers not only need to be familiar with the M2M standard protocol, but also need to develop and build WSDL Web Services servers by themselves, and use the JAVASDK of the M2M-A protocol to build applications. In addition, it is necessary to have the ability to operate the WSDL Web Services server; the WSDL Web Services servers developed and built by each IoT application developer are for their own use alone, and cannot be well provided to other developers. It is wasteful and requires repeated investment in construction, which cannot improve the development efficiency of application developers accessing the IoT service platform.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. In addition, each of the following embodiments is an optional solution of the present invention, and the arrangement sequence and number of the embodiments have nothing to do with their preferred execution order.

Example 1

This embodiment provides a data transmission method in the Internet of Things system. Before implementing this method, it is considered that many industrial sensing devices often use their proprietary protocols, so the respective protocol formats are different, and for the same measured value Interpretation is also different, so it is necessary for the user to input the basic information of the industrial sensing device (such as the identification of the industrial sensing device) and the protocol configuration information of the private protocol used by the industrial sensing device to the M2M gateway user.

Among them, the protocol configuration information includes the protocol configuration information of the business flow data and the protocol configuration information of the management flow data; the protocol configuration information for the business flow data includes: the data frame header and its corresponding business packet length, the output format of valid data and its interpretation Meaning, alarm threshold, data frame tail and its corresponding service packet length; protocol configuration information for management flow data includes: data frame header and its corresponding management packet length, valid data output format and its interpretation meaning, alarm threshold, data frame tail and its corresponding management packet length.

Correspondingly, in this embodiment, the M2M gateway corresponds to the above-mentioned protocol configuration information that needs to be input by the user, and correspondingly has some configuration options, which can record the basic information and protocol configuration information of the industrial sensing device input by the user, and the basic information and the corresponding protocol There is a corresponding relationship between the configuration information, which is used to correspond to its subordinate protocol configuration information according to the identification of the industrial sensing device, which can correspond to the interpretation meaning of the format and specific value of the private protocol used by the industrial sensing device.

Further, after the M2M has finished recording the basic information and protocol configuration information of the industrial sensing device input by the user, the method of this embodiment further includes: the M2M gateway synchronizes the basic information and the protocol configuration information to the IoT platform and the middleware platform ( In this embodiment, it is specifically the M2MAH server middleware platform); in the preferred solution, after receiving the information of the M2M gateway, the Internet of Things platform sends a confirmation message to the M2M gateway, and the received information of the M2M gateway is: received from the M2M gateway Basic information and protocol configuration information. After the M2MAH server middleware platform receives the information of the M2M gateway forwarded by the Internet of Things platform, it can also send a confirmation message to the M2M gateway through the Internet of Things platform.

The purpose of synchronizing basic information and protocol configuration information to the Internet of Things platform and middleware platform is to allow industrial sensing devices to register with the Internet of Things platform and M2MAH server middleware platform, and realize the Internet of Things platform, M2MAH server middleware platform and M2M gateway Synchronization on data. After synchronization, both the IoT platform and the M2MAH server middleware platform will save the basic information and protocol configuration information of the sensor equipment in this industry, so that when the subsequent sensor equipment in the industry transmits data, the IoT platform and the M2MAH server middleware platform can identify the device.

The method in this embodiment will be specifically described below in conjunction with the scenario shown in FIG. 1 . There are four types of protocol interfaces among the devices in FIG. 1 : -S interface, -T interface, -A interface and HTTP interface. -S interface: the interface between the industrial sensor device and the M2M gateway; -T interface: the interface between the M2M gateway and the IoT service platform; -A interface (for WMMP-A protocol): the IoT service platform and M2MAH Interface between server middleware platforms; HTTP interface (for HTTP protocol): remote interface between M2MAH server middleware platform and enterprise applications. As shown in Figure 2, the method includes:

101. After the industrial sensing device is successfully registered on the M2M gateway, the Internet of Things platform, and the M2MAH server middleware platform, it sends data to the M2M gateway, and the data includes business flow data and/or management flow data;

102. The M2M gateway receives the data sent by the industry sensor device, and searches for the protocol configuration information subordinate to the industry sensor device according to the identification of the industry sensor device in the data, and then converts the protocol format and interpretation meaning of the data into The protocol recognized by the M2M gateway;

The data sent by the industry sensor device is in the format of the private protocol. Since the M2M gateway records the proprietary protocol identification method of the private protocol of the industry sensor device, when the data of the industry sensor device is transmitted to the M2M gateway, the M2M gateway can according to the The data packet in the private protocol format calls the exclusive protocol configuration information, and completes the standardized conversion of the private protocol format data according to the protocol configuration information.

For example: the M2M gateway will have a configuration tool interface. This configuration interface includes input fields such as data frame header, packet length, frame identifier, data entity, alarm threshold, and data frame tail. The interpretation meaning of the format is filled in separately according to the above configuration interface. If the analysis of data entities and alarm thresholds can be set through the configuration interface (such as classic data conversion methods such as addition, subtraction, multiplication, and division), the user can confirm the configuration interface. Afterwards, the data packet in the private protocol format sent by the industrial sensing device will be encapsulated into a standardized format by the M2M gateway.

103. The M2M gateway encapsulates the converted data into an applicable protocol of the IoT platform, such as the standardized format of the applicable protocol of the -T interface, and sends the encapsulated data (management flow data and/or business flow data) to the IoT platform;

Since the interpretation meaning and protocol format of the converted data are recognized by the M2M gateway, the converted data can be standardized and packaged in a format recognizable by the Internet of Things platform, so it can be achieved without the need for industry sensor equipment Any transformation, without re-customizing the communication adapter, can improve the technical effect of the efficiency of industrial sensor equipment access to the Internet of Things service platform.

104. After receiving the data sent by the M2M gateway, the IoT platform sends a confirmation message to the M2M gateway.

In the preferred solution, in order to ensure the reliability of data transmission between the M2M gateway and the industry sensor device, the method of this embodiment may further include:

The M2M gateway detects in real time whether the connection with the industry sensor equipment is normal, and if it detects that the connection is abnormal, it establishes a connection with the industry sensor equipment it belongs to.

105. After receiving the confirmation message fed back by the Internet of Things platform, the M2M gateway sends the confirmation message to the terminal.

106. As shown in FIG. 3, the IoT platform stores the converted data and sends the data to the M2MAH server middleware platform;

107. The M2MAH server middleware platform parses the key information from the data, and determines the protocol type of the key information according to the type of the small message body in the key information, adds a corresponding identification to the determined protocol type, and according to the identification and the preset state The computer converts the key information into the protocol format, which is the data recognized by the enterprise application side;

Wherein, the key information includes: version information, message header, message body type, message length, packet serial number and message body.

Specifically, the above step 107 can be realized in the following manner:

The M2MAH server middleware platform caches the arriving data in the WMMP-A protocol format, and determines whether it needs to be stored in the DB database according to the application requirements of the enterprise; the M2MAH server middleware platform parses the data in the WMMP-A protocol format, according to the The definition of -A protocol format extracts key information such as xml version information, message header, message type, message length, message body, and packet serial number; the M2MAH server middleware platform determines the protocol type of the data according to the message body type (the protocol The type is different from the protocol type of the transmission protocol mentioned in step 102 or 103, but under a certain transmission protocol format, it defines the data format type that the data is dedicated to a certain role or function. For example, the data is of business flow data The data format type or the data format type of management flow data? If the message body type is management flow data, it is also necessary to determine whether it is a control instruction or a registration instruction, etc.); the M2MAH server middleware platform determines the message body type according to the pre-established state machine pair Identify each part of the data, such as message body, message header, etc., and convert the data identifying the message body type of each part into HTTP protocol format data according to the HTTP format.

108. The M2MAH server middleware platform checks the integrity of the data converted into the HTTP protocol to ensure the accuracy of the conversion result. If the verification is passed, only step 109 is needed; otherwise, it will wait for receiving data from the Internet of Things platform again, and return to step 107 for execution.

Wherein, the integrity check may be implemented by using an existing parity check or a cyclic redundancy check code (Cyclic Redundancy Check, CRC) check.

109. Send the converted and verified data identified by the enterprise application end, such as data in HTTP format, to the enterprise application end.

In the method provided by this embodiment, the M2M gateway can record the protocol configuration information and basic information input by the user, and can realize the registration of the terminal device and the effect of adapting to the Internet of Things platform after the protocol configuration, thereby eliminating the need to It is necessary to modify the terminal equipment during the existing adaptation, or realize the remote access of the IoT platform of the terminal equipment by connecting a hardware adapter; in addition, the M2MA2H server middleware platform in this method can integrate the complex WMMP The -A protocol is transformed into simple HTTP, so enterprise application developers do not need to build WSDL web services servers themselves, but only need to develop M2M applications that support the HTTP protocol, thus realizing the ability of all network devices to flexibly access the IoT service platform. Therefore, the method proposed in this embodiment saves the cost and time of M2M terminal customization transformation and development, or the cost of connecting hardware adapters, improves the efficiency of industrial sensor equipment accessing the Internet of Things service platform, and saves development costs; at the same time It simplifies the M2M application development process, reduces the cost of operating application servers for enterprise users, and improves the efficiency of enterprise development of M2M applications.
