[0018] See Figure 1As shown, a remote control device for a switch according to the present invention includes: a main control module 1, a remote control module 2, and a slave control module 3.

[0019] Maintenance personnel generate remote control signals by operating the remote control module 2 to restart the switch 4 through the main control module 1 and the slave control module 3. Compared with the traditional restart process, maintenance personnel do not need to go to the fault site to restart the switch 4, which greatly shortens the processing time, improves the restart efficiency, and further avoids the impact range from increasing due to the prolonged fault of the switch 4.

[0020] In one embodiment of this utility model, see Figure 2-4 As shown, the main control module 1 includes a main control unit 101, a main power supply unit 102, and a DC monitoring unit 103; the main control unit 101 is connected to the main power supply unit 102, the DC monitoring unit 103, and the remote control module 2, and the DC monitoring unit 103 is connected to the slave control module 3.

[0021] In one embodiment of this utility model, see Figure 5-7 As shown, the remote control module 2 includes a communication unit 201, a power supply unit 202, and a remote control unit 203; the communication unit 201 is connected to the power supply unit 202, the remote control unit 203, and the main control module 1, and the power supply unit 202 is connected to the remote control unit 203.

[0022] In one embodiment of this utility model, the main control unit 101 is an ESP32 microcontroller with wireless communication function; the remote control unit 203 is an ESP8266 microcontroller with wireless communication function. The connection relationship between the communication unit 201 and the main control module 1 is that the communication unit 201 and the main control unit 101 are connected through wireless communication function, so that maintenance personnel can restart the switch 4 without going to the previous fault point.

[0023] In one embodiment of this utility model, see Figure 8-10As shown, the control module 3 includes a first slave control unit 301, a second slave control unit 302, and a seamless switching unit 303; the main control module 1 is connected to the first slave control unit 301 and the second slave control unit 302, the seamless switching unit 303 is connected to the first slave control unit 301 and the second slave control unit 302, and the switch 4 is connected to the first slave control unit 301 and the second slave control unit 302; the connection relationship between the main control module 1 and the first slave control unit 301 and the second slave control unit 302 is as follows: the DC monitoring unit 103 is connected to the first slave control unit 301 and the second slave control unit 302.

[0024] In one embodiment of this utility model, see Figure 10 As shown, the seamless switching unit 303 includes a first switching circuit 3031, a second switching circuit 3032, and a switching switch 3033; the first switching circuit 3031 is connected to the second switching circuit 3032 through the switching switch 3033, the first switching circuit 3031 is connected to the first slave control unit 301, and the second switching circuit 3032 is connected to the second slave control unit 302.

[0025] When the first slave control unit 301 malfunctions, the connection between the first switching circuit 3031 and the first slave control unit 301 is disconnected by the switch 3033, while the connection between the second switching circuit 3032 and the second slave control unit 302 is connected, so that the switch 4 can be remotely controlled through the second slave control unit 302; conversely, when the second slave control unit 302 malfunctions, the connection between the second switching circuit 3032 and the second slave control unit 302 is disconnected by the switch 3033, while the connection between the first switching circuit 3031 and the first slave control unit 301 is connected, so that the switch 4 can be remotely controlled through the first slave control unit 301.

[0026] In one embodiment of this utility model, both the first slave control unit 301 and the second slave control unit 302 include a relay, an input circuit, and an output circuit; the relay is connected to the input circuit and the output circuit, the input circuit is connected to the main control module 1, and the output circuit is connected to the switch 4.

[0028] The first slave control unit 301 and the second slave control unit 302 operate on the same principle. The following explanation uses the first slave control unit 301 as an example to illustrate the working principle of restarting the switch 4 using this invention: The maintenance personnel generate a remote control signal through the remote control unit 203 and send it to the main control unit 101 through the wireless communication function of the communication unit 201. The main control unit 101 generates a control signal based on the remote control signal and sends it to the first slave control unit 301 through the DC monitoring unit 103. When the first control unit 301 receives a control signal, the relay RLY1 switches from the energized state to the de-energized state. After a preset time, the relay RLY1 returns to the energized state from the de-energized state, thereby restarting the switch 4. The preset time can be set according to actual needs. After relay RLY1 is restored to the energized state, the first slave control unit 301 also receives the input and output signals of switch 4 and sends them to the main control unit 101 through the DC monitoring unit 103. The main control unit 101 generates a feedback signal based on the input and output signals and sends it to the communication unit 201 through the wireless communication function of the main control unit 101, so that maintenance personnel can determine whether switch 4 has been successfully restarted through the remote control module 2.

[0029] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
