The communication instructions in the communication process between the human-computer interaction module of the present invention and the power distribution automation terminal are divided into three parts: issuing file instructions, summoning file instructions and confirming issued file effective instructions:

Among them, the working process of the human-computer interaction module issuing file instructions to the distribution automation terminal is shown in Figure 5, including the following steps:

Step 1, the human-computer interaction module sends a file transmission command (type identification TI=120, transmission reason COT=6) to the power distribution terminal, and the command message should include the size and CRC check code information of the parameter file to be downloaded;

Step 2, the power distribution terminal confirms that the file transfer command has been received (type identifier TI=120, transfer reason COT=7), stores the parameter file size, CRC check code information, and executes the file transfer process;

Step 3, the human-computer interaction module transmits files to the power distribution terminal (type identification TI=121, transmission reason COT=13), and each packet of data message includes data content starting address, length and CRC check code information;

Step 4, the power distribution terminal checks the CRC of each packet data message, if correct, store the data information in the message; as wrong, reply a negative confirmation message (type identification TI=121, transmission reason COT=47);

Step 5, the human-computer interaction module sends the last packet of data message (type identification TI=123, transmission reason COT=13), after the power distribution terminal verifies that it is correct, the data packet is combined, according to the previously stored file size, CRC calibration Check the information and check the correctness of the file;

Step 6, the power distribution terminal confirms that the file is generated correctly, sends a file approval message (type identification TI=124, transmission reason COT=6) to the human-computer interaction module, and the human-computer interaction module replies to confirm (type identification TI=124, transmission reason COT=7), the file transfer process ends. If the power distribution terminal confirms that the file is generated incorrectly, it sends a file negative approval message (type identifier TI=124, transmission reason COT=46) to the human-computer interaction module, and the human-computer interaction module sends the file again.

Among them, the working process of the human-computer interaction module calling the file command to the distribution automation terminal is shown in Figure 6, including the following steps:

Step 1, the human-computer interaction module sends a calling file command (type identification TI=122, transmission reason COT=6) to the power distribution terminal, specifies a parameter group, and defines the length of the file transmission package;

Step 2, the power distribution terminal extracts the relevant parameters of the specified parameter group of the human-computer interaction module, generates a file, calculates the length of the data content and the CRC checksum, and replies for confirmation (type identification TI=122, transmission reason COT=7), the human-computer interaction module Store data content length and CRC checksum information;

Step 3, the power distribution terminal subpackages the data content according to the length of the file transmission package defined by the human-computer interaction module, and transmits the file to the human-computer interaction module (type identification TI=121, transmission reason COT=13), each packet of data message Both include data content CRC checksum information;

Step 4, the human-computer interaction module checks each packet of data message uploaded by the power distribution terminal, and verifies the accuracy of the data content. If it is correct, it will store the data information in the message; if it is wrong, it will reply a negative confirmation message (type identification TI=121, transmission reason COT=47);

Step 5. The power distribution terminal sends the last packet of data message (type identifier TI=123, transmission reason COT=13). After the human-computer interaction module replies and confirms, the data packet is combined and analyzed, and the file length and CRC check are verified And, confirm the correctness of the file;

Step 6, the human-computer interaction module confirms that the file is correct, sends a file approval message (type identification TI=124, transmission reason COT=6) to the power distribution terminal, and the power distribution terminal replies to confirm (type identification TI=124, transmission reason COT=6) 7), the calling file process ends. If the human-computer interaction module confirms that the file is generated incorrectly, it sends a file negative approval message (type identifier TI=124, transmission reason COT=46) to the power distribution terminal, and the power distribution terminal re-uploads the file.

Among them, the working process of the human-computer interaction module confirming and issuing the document effective instruction to the distribution automation terminal is shown in Figure 7, including the following steps:

Step 1. After the power distribution terminal sends a correct confirmation message to the file parameters delivered by the human-computer interaction module, it waits for the document validation command issued by the human-computer interaction module.

Step 2, the human-computer interaction module sends the file (specified parameter group) effective command (type identification TI=127, transmission reason COT=6) to the power distribution terminal, and the power distribution terminal replies to confirm (type identification TI=127, transmission reason COT= 7) Execute the file start command (overwrite the original parameter configuration file in the device).
