Problems solved by technology

Among them, the coding of the anti-mistake locks has gone through four coding methods: contact coding, ID coding, non-contact photoelectric coding, and electromagnetic coding. Using the above methods to code the anti-mistake locks, the computer key can recognize the codes of the locks reliably. The reliability is not high, and the code in the lock cannot be set repeatedly, which is not conducive to the maintenance, capacity expansion and upgrading of the substation
Moreover, the unlocking of the lockset by the computer key needs to be done manually by pressing the unlocking button, and then through the mechanical transmission unlocking shaft to realize manual unlocking. A master key that can be unlocked arbitrarily has a great potential safety hazard, and manual unlocking is difficult to operate with one hand, which is very inconvenient

Abstract

The invention provides a microcomputer misoperation prevention locking device which comprises a control device provided with an operation system, a simulation screen control device, an intelligent lock, a printing apparatus and a monitoring device. The control device is a PC industrial personal computer which is provided with a connection port. The intelligent lock comprises a computer key provided with a Bluetooth data transmission device, a coding lock using a non-contact IC encoding manner and a computer key adapter capable of charging and being communicatively connected with the computer key. The computer key adapter is connected with the connection port of the PC industrial personal computer. The total operation process of the invention is simple and visible, and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of preventing misoperation of electric power systems, in particular to a microcomputer anti-misoperation locking device. Background technique [0002] The microcomputer anti-misoperation locking device is a product specially developed and produced to prevent five kinds of misoperation accidents in the power system. It has strong operation ticket management and five prevention functions. The "five defenses" include: prevent accidental entry into the charged interval; prevent accidental closing of the circuit breaker; prevent the isolation switch from being pulled and closed with load; ). [0003] The currently used microcomputer anti-misoperation locking device is mainly composed of a control device, an analog screen controller, an anti-misoperation lockset, a printing device, and a monitoring device. Among them, the coding of the anti-mistake locks has gone through four coding methods: contact coding, ID c...
