AI Technical Summary
[0006]本发明的目的在于改善现有的压板设备的状态信息与防误控制相互脱节，难以准确判断压板设备的可操作状态，导致压板设备可能出现误操的问题，提供一种闭锁防误操作系统及其操作方法
[0031] By integrating a locking and anti-misoperation device with the pressure plate equipment, this device combines a first detector, a second detector, a lock cover, a lock body, a drive assembly, and a control circuit board. This enables comprehensive monitoring and logical linkage of the pressure plate equipment's status and the lock cover's position. The first detector monitors the pressure plate equipment's engagement/disengagement status in real time, while the second detector monitors the lock cover's movement position. The control circuit board determines whether the pressure plate equipment is currently operational based on the detection signals from both. Only when the lock cover is in the second movement position (unlocked state) is the operator allowed to perform the engagement/disengagement operation. Compared to existing technologies where status detection and anti-misoperation locking are disconnected, this invention organically combines pressure plate equipment status detection, lock cover position detection, and operation permission control. This allows the backend system or computer key to simultaneously obtain the real-time status of the pressure plate equipment and whether it is operational. This fills the technological gap in preventing misoperation of secondary equipment, eliminating electrical misoperation accidents caused by missed, incorrect, or improper engagement/disengagement of the pressure plate, and significantly improving the intelligence level of substation secondary equipment anti-misoperation and the safety of power grid operation.
