Code chip for anti-misoperation locking system, anti-misoperation locking system and working method thereof

Abstract

The invention provides a code chip for an anti-misoperation locking system, an anti-misoperation locking system and a working method thereof, in which a mechanical code and an electronic code are arranged on the same code chip; the anti-misoperation locking system includes a lock and an unlocking device; the lock includes a lock body and the above-mentioned chip; the unlocking device includes: a housing, a probe part, a data storage circuit, an unlocking mechanism, an unlocking mechanism control circuit, and a control circuit; without changing the shape of the original lock, the above-mentioned chip can be directly replaced to make the original Locks can be coded mechanically or electronically, which has completely changed the situation that only one code can be used for locks in the past; the working method of the anti-misoperation locking system can select the type of unlocking device according to the actual situation on site, and can be mechanically The device is identified by code or electronic code. In actual use, the present invention reasonably integrates user resources and increases the working efficiency and safety performance of the anti-misoperation locking system.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a code chip for an anti-misoperation locking system, an anti-misoperation locking system and a working method thereof. Background technique [0002] In order to prevent human-operated accidents, microcomputer anti-misoperation locking systems are commonly used in substations and power plants to lock operating equipment such as circuit breakers, knife switches, grounding wires, and net doors. The locking devices used generally include mechanical locks and electric coded locks. etc., the purpose is to prevent human misoperation. In order to manage and operate this type of locking lock, it needs to be coded. The traditional coding method includes the early mechanical coding and the electronic coding currently in use. The two coding methods are incompatible with each other, and the mechanically coded locks are adopted. Not recognized by an electronically encoded unloc...

AI Technical Summary

Problems solved by technology

In order to manage and operate this type of locking lock, it needs to be coded. The traditional coding method includes the early mechanical coding and the electronic coding that is currently in use. The two coding methods are incompatible with each other, and the mechanically coded locks are adopted. Cannot be recognized by an electronically encoded unlocking computer key and vice versa

[0003] With the development of the microcomputer anti-misoperation locking system of electric power, a centralized control station management mode has emerged. The centralized control station management mode requires the centralized operation of the microcomputer anti-misoperation locking systems of these substations and power plants that were originally installed scatteredly. The delivery time is different. Some locks use mechanical coding, and some locks use electronic coding. Due to the different coding methods of these locks, it seriously hinders the promotion of centralized control station management mode.

[0004] In addition, because the mechanically coded lock is an early lock, the latest technology is to use an electronic code chip; at the same time, the failure rate of the early lock is high. Due to the special operation mode of the power system, it is difficult to cut off the power easily. Upgrade to Electronic Encoding Chip System

It poses a great hidden danger to the safe operation of the power system.
