Please refer to FIG. 1. FIG. 1 is a first flowchart of a method for detecting communication of a power distribution terminal according to an embodiment of the present application.

A power distribution terminal communication detection method provided by an embodiment of the present application, applied to a CPU of a power distribution terminal, may include the following steps:

Step S101: Detect whether the communication link between the encryption modules connected to the power distribution terminal is normal, and generate a first detection result.

In practical applications, when the power distribution terminal exchanges information with the power distribution automation master station, the CPU (Central Processing Unit) of the power distribution terminal can first send the data to the encryption module, and then the encryption module sends the data to the encryption module. Communication module, the communication module sends data to the distribution automation master station, so when the distribution terminal and the distribution automation master station cannot communicate, there may be a problem with the encryption module connected to the distribution terminal, or the distribution If there is a problem with the communication module of the terminal, etc., it is possible to first detect whether the communication link between the encryption modules connected to the power distribution terminal is normal, and generate a corresponding first detection result. The type of the encryption module can be determined according to actual needs, for example, it can be a security chip. Please refer to FIG. 2, which is a schematic diagram of the communication between the power distribution terminal and the power distribution automation master station.

Step S102: Detect whether the communication link between the communication module of the power distribution terminal and the power distribution automation master station is normal, and generate a second test result.

In practical applications, after the CPU of the power distribution terminal generates the first detection result, it can detect whether the communication link between the communication module of the power distribution terminal and the power distribution automation master station is normal, and generate the second detection result. The type of the communication module may be determined according to a specific application scenario, for example, it may be a wireless communication module, a wired communication module, etc., which is not specifically limited in this application.

Step S103: Display the first detection result and the second detection result.

In practical applications, after the CPU of the power distribution terminal generates the first test result and the second test result, it can display the first test result and the second test result, so that the outside world such as the user can determine according to the first test result and the second test result. The communication state of the power distribution terminal, and then the power distribution terminal is adjusted according to the first detection result and the second detection result.

A power distribution terminal communication detection method provided by the present application is applied to the CPU of the power distribution terminal, detects whether the communication link between the encryption modules connected to the power distribution terminal is normal, and generates a first detection result; Check whether the communication link between the communication module and the power distribution automation master station is normal, and generate a second detection result; display the first detection result and the second detection result. The present application provides a communication detection method for a power distribution terminal. The CPU of the power distribution terminal actively detects whether the communication link between the encrypted modules connected to the power distribution terminal is normal, and detects whether the communication module of the power distribution terminal is connected to the power distribution automation master station. Whether the communication link between them is normal, the corresponding test results are obtained, and the test results are displayed, so that the outside world can clearly know the communication status of the power distribution terminal according to the test results displayed by the CPU, so as to avoid communication with the power distribution terminal when the power distribution terminal cannot communicate. Compared with the prior art, the electrical automation master station can automatically detect the abnormal cause of encrypted communication of the power distribution terminal and notify the outside world to improve the operation and maintenance efficiency.

The present application provides a communication detection method for a power distribution terminal. When the CPU of the power distribution terminal detects whether the communication link between the encryption modules connected to the power distribution terminal is normal and generates a first detection result, it can send a first test report. Text to the encryption module; determine whether to receive the first response message corresponding to the first test message returned by the encryption module, if so, generate a first detection result indicating that the communication link with the encryption module is normal; if not, Then, a first detection result indicating that the encryption module is abnormal is generated.

In a specific application scenario, it takes time for the encryption module to return the first response packet, and whether the encryption module can return the first response packet may be affected by other factors, etc., all of which will prevent the CPU from obtaining the first response packet in the first time. , and then the CPU generates the first detection result indicating the failure of the encryption module. However, at this time, the encryption module does not necessarily fail. Therefore, in order to improve the generation accuracy of the first detection result, it is judged whether to receive the return of the encryption module and the first detection result. When a first response message corresponding to the test message is tested, a first timer can be started, and the duration of the first timer is a preset duration; and it is judged whether the first response message is received within the timing duration of the first timer; If the first response message is not received within the timing of the first timer, the real-time number of times the first response message is not received is accumulated; it is determined whether the real-time number is greater than or equal to the preset number; if the real-time number is less than the preset number , then return to execute the step of sending the first test message to the encryption module; if the real-time number of times is greater than or equal to the preset number of times, it is determined that the first response message corresponding to the first test message returned by the encryption module is not received. That is, by extending the time required for the CPU to receive the first response packet and increasing the number of times that the CPU allows the encryption module to fail to send the first response packet in time to improve the generation accuracy of the first detection result, the duration of the first timer can be Determined according to actual needs, such as 1 minute, etc., and the preset number of times can also be determined according to actual needs, such as 3 times, etc.

Signal strength, the first duration is determined based on the signal strength. Correspondingly, when generating the second detection result indicating that the communication link between the communication module of the power distribution terminal and the power distribution automation master station is abnormal, the communication connection between the communication module and the power distribution automation master station can be tested directly through the test command.
