Problems solved by technology

But this opening / locking mechanism still has its own shortcoming: 1. The unlocking torque of mechanism (the product of the active force that human body exerts and the gear index circle radius of unlocking mechanism) is small; It takes several seconds to complete one operation, and the power consumption is relatively large; 3. Due to the large shape and volume of the opening / locking mechanism, the entire computer key has a large shape

Abstract

An intelligent key consists of shell, ID coding head, control unit and unlocking mechanism. The said unlocking mechanism is prepared as engaging rack with gear on electrode shaft, electric-connecting electromagnet and mechanism state detection unit as well as ID coding head with control unit, setting two reset springs at internal side of handle, setting said electromagnet to be bistable state electromagnet and placing handle at external end of rack long axis direction.

Description

technical field [0001] The invention relates to the technical field of anti-misoperation locking of power systems, in particular to a microcomputer anti-misoperation locking device and its components used in power plants or power stations and other distribution power plants to prevent misoperation. Background technique [0002] At present, in the existing microcomputer anti-misoperation locking device, a smart key (commonly known as a computer key) with a code recognition function is generally used to cooperate with a mechanical lock to complete the anti-misoperation locking function; the computer key has a coding head located on the casing and a The opening / closing mechanism in the casing as the most important actuator of the computer key; the commonly used opening / closing mechanisms include push button type, button type and wheel type, and the opening / closing mechanism generally includes a mechanism state detection unit , electromagnet, gear transmission mechanism and othe...
