To operate and maintain the transmission and distribution switch, the operation and maintenance personnel need to regularly inspect and manually operate these transmission and distribution switches. For some transmission and distribution switches with relatively discrete distribution areas, the operation and maintenance efficiency is very low. Therefore, it is of great theoretical and practical significance to quickly operate and maintain the transmission and distribution switch to improve the operation efficiency of the power system.

[0009] Step S4: The power transmission and distribution switch equipment performs corresponding operations according to the received remote control instructions and provides feedback.

[0010] Furthermore, the process of registering the transmission and distribution switchgear includes:

[0011] Upload the basic information of the power transmission and distribution switchgear to the remote operation terminal, wherein the basic information of the power transmission and distribution switchgear includes IMEI number information and the location of the power transmission and distribution switchgear;

[0012] Generate a corresponding authentication key according to the uploaded basic information of the power transmission and distribution switchgear, and after starting the power transmission and distribution switchgear, input the corresponding authentication key, and send the input authentication key to the remote operation terminal;

[0013] Furthermore, the process of remote association authentication between the remote operation terminal and the power transmission and distribution switch equipment includes:

[0014] The remote operation end reviews the received authentication key. If the review is passed, it generates a private IP address, and generates a corresponding device identification code based on the generated private IP address. The device identification code is associated with the private IP address, and the device identification code is assigned to the corresponding power transmission and distribution switch equipment, completing the remote association authentication between the remote operation end and the power transmission and distribution switch equipment.

[0015] Furthermore, the process of establishing the 5G communication channel between the power transmission and distribution switch equipment and the remote operation terminal includes:

[0024] Similarly, the data block obtained from the last round of encryption is used as the final encrypted remote control instruction and feedback information to complete the encryption of the 5G communication channel between the power transmission and distribution switch equipment and the remote operation terminal.

[0025] Furthermore, the process of transmitting the input remote control command to the corresponding power transmission and distribution switchgear through the 5G communication channel includes:

[0026] When a power transmission and distribution switch device needs to be turned on, a remote control instruction is input through the remote operation terminal. The remote control instruction includes the device identification code of the power transmission and distribution switch device and the power transmission and distribution switch.

[0027] Perform an XOR operation on the data block and the key, divide the XORed data block into several 4x4 matrices, and perform multiple rounds of encryption cycles on the data block. Each round of encryption cycle includes keeping the first row of each 4x4 matrix unchanged, cyclically shifting the second row to the left by one byte, cyclically shifting the third row to the left by two bytes, and cyclically shifting the fourth row to the left by three bytes, and converting the 4x4 matrix into a data block and performing an XOR operation on the key;

[0028] Similarly, the data block obtained by the last round of encryption is used as the final encrypted remote control instruction;

[0029] After the encryption is completed, the encryption key and the encrypted remote control command are transmitted to the power transmission and distribution switch device according to the obtained private IP address of the power transmission and distribution switch device.

[0030] Furthermore, the specific process of the power transmission and distribution switch equipment parsing and executing the received remote control command includes:

[0031] After receiving the key and the encrypted remote control instruction, the power transmission and distribution switch device uses the key to decrypt the encrypted remote control instruction, restores the data block to a binary data stream, converts the binary data stream into ASCII code, converts the ASCII code into a string, converts the string into a remote control instruction, and the power transmission and distribution switch device reads the remote control instruction and turns on the power transmission and distribution switch;

[0032] Furthermore, the specific process of the power transmission and distribution switchgear providing feedback after executing the remote control instruction includes:

[0033] After the power transmission and distribution switch equipment performs the operation of turning on the power transmission and distribution switch, it sends feedback information to the remote operation end through link 2. The feedback information first reaches node 1 to obtain the IP address of the remote operation end. The feedback information reaches node 2 and is encrypted. After the encryption is completed, the encryption key and the encrypted feedback information are transmitted to the remote operation end according to the obtained IP address of the remote operation end.

[0034] After the remote operation end receives the key and the encrypted feedback information, it uses the key to decrypt the encrypted feedback information, restores the data block to a binary data stream, converts the binary data stream into ASCII code, converts the ASCII code into a string, and converts the string into feedback information. The remote operation end reads the feedback information, confirms that the operation of turning on the power transmission and distribution switch has been executed, and the remote control of the power transmission and distribution switch is completed.
