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.

Embodiment
[0089] Such as figure 1 , 2 , 3, 4a, 4b, 4c, 5a, and 5b, the code chip 13 used in the anti-mislocking system of this embodiment, preferably, the mechanical code bit 1 of the code chip 13 is located directly above the housing 2, and the housing The body 2 is also provided with a mounting hole 15; the mechanical coding position 1 includes: a code retention position 8 composed of a plurality of coding rods and a code removal position 9 formed by removing the gap of the coding rods.
[0090] Such as figure 1 , 3 , the mechanical coding bit 1 of the present invention is made up of a plurality of "protrusions" and small "rods", that is, coding reserved bits 8 are formed, and coding is carried out according to binary bits. "Rod", when the code binary is "0", break off the "protruding" small "rod"; when unlocking the computer key device to read the mechanical code, through the mechanical probe placed in front of the device and the corresponding position switch 7 implementation, wh...

The invention provides a chip used for an anti-misoperation locking system, the anti-misoperation locking system and a working method of the anti-misoperation locking system. A mechanical code and an electronic code are set on the same chip; the anti-misoperation locking system comprises a lockset and an unlocking device; the lockset comprises a lock body and the chip; the unlocking device comprises a shell, a probe component, a data storage circuit, an unlocking mechanism, an unlocking mechanism control circuit and a control circuit; under the condition that the shape of an original lockset is not changed, the chip is directly replaced, so that not only can the mechanical code be used by the original lockset but also the electronic code can be used, and therefore, the condition that only one code can be used by the lockset in the past is thoroughly changed; according to the working method of the anti-misoperation locking system, the type of the unlocking device can be selected according to the on-site actual condition, and equipment can be identified through the mechanical code or the electronic code. In the actual use of the chip, the anti-misoperation locking system and the working method of the anti-misoperation locking system provided by the invention, user resources are reasonably integrated, and the working efficiency and the safety performance of the anti-misoperation locking system are improved.
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...
