Gate control failure monitoring protection device and control method

The invention provides a gate control failure monitoring protection device and a control method, relating to the technical field of key mine security such as electric braking protection in emergency braking performance monitoring and braking failures of a gate control system for mine hoist hydraulic braking. An independent UPS power supply, a PLC, and an incremental encoder are employed, the drive logic and process protection of an original hoist system are not affected. The real-time monitoring and recording of braking performance of a braking distance, a braking time, a braking deceleration in emergency braking of the gate control system is realized. The logic judgment of a gate control failure state is added, and a transmission device is enabled to carry out electric braking on motor secondary power-on. A man-machine interface HMI is used to display braking performance and alarm information in real time. According to the device, the improvement of the security of a mine hoisting system is facilitated. 种闸控失
