Title:
INTELLIGENT RESTART SYSTEM FOR WIRELESS TERMINAL OF HIGH-VOLTAGE SWITCH
Document Type and Number:
WIPO Patent Application WO/2021/007880
Kind Code:
A1
Abstract:
Disclosed is an intelligent restart system for a wireless terminal of a high-voltage switch. A high-voltage switch control loop is connected to a wireless communication module, the wireless communication module is in wireless communication with a control center, and a power supply module supplies power to the high-voltage switch control loop and the wireless communication module. A restart circuit is also comprised, wherein same is used for receiving a wireless control signal from the control center and controlling the turning on and off of circuits between a power supply device and the high-voltage switch control loop and between the power supply device and the wireless communication module. The control center tests the signal quality between same and the wireless communication module, and when the delay duration of signal transceiving exceeds a preset value, the control center transmits a turn-off signal to the restart circuit. In the present invention, by means of remotely controlling a wireless communication module, a power source of a device is automatically powered off and restarted, such that the problem of a communication fault can be effectively solved; in addition, the function of a timed restart is realized by using a timer, such that controllability is achieved, thereby improving the intelligence level of the operation of a high-voltage switch, and laying the foundation for building a safe, stable and intelligent regional power grid.
