Cylinders and locksets with dual control, grade coding and status self-test

Abstract

The invention provides a lock cylinder with dual control, graded coding and state self-test, comprising an intelligent key, a lock cylinder code chip and a lock cylinder, the unlocking shaft of the intelligent key is provided with a key code chip; It is composed of a lock cylinder, and the inner lock cylinder includes a password rotating lock cylinder and a fixed lock cylinder; there are also graded group coding marbles between the password rotating lock cylinder and the fixed lock cylinder and the bottom marble. The combination of the identification code achieves dual control and axial hierarchical management; the unlocking shaft and the password rotate the electromagnet core, magnetic core and lock pin on the lock cylinder; in addition, the password set on the lock cylinder rotates the lock cylinder and fixes the lock cylinder The internal optical signal channel can effectively collect the relative positions of the password rotating cylinder and the fixed lock cylinder, so as to judge the working state of the lock cylinder, and can provide and feedback the opening and locking working states of the lock cylinder in real time; the invention also provides dual control, Locks with graded coding and state self-testing cylinders.

Description

[0001] 【Technical field】 [0002] The invention relates to a lockset in an industrial error prevention system, in particular to a lock cylinder with dual control, hierarchical coding and state self-test. [0003] 【Background technique】 [0004] At present, many electric power, energy, industrial and mining enterprises manage, operate and repair equipment, or deal with emergency failures. Since personal safety and equipment safety are involved, all activities must be carried out in accordance with strict rules and regulations to prevent accidents. , bring risks and losses to individual enterprises, and it is not uncommon to see cases of major accidents due to non-compliance with operating procedures. In order to overcome this problem, a comprehensive anti-mistake management protection system is generally adopted; Operators ignored the rules and regulations and did not follow the regulations, resulting in risky accidents.

[0004] At present, many electric power, energy, industrial and mining enterprises manage, operate and repair equipment, or deal with emergency failures. Since personal safety and equipment safety are involved, all activities must be carried out in accordance with strict rules and regulations to prevent accidents. , bring risks and losses to individual enterprises, and it is not uncommon to see cases of major accidents due to non-compliance with operating procedures. In order to overcome this problem, a comprehensive anti-mistake management protection system is generally adopted; Operators ignore the rules and regulations and do not follow the regulations, resulting in risk accidents

[0005] In the underlying protection of the comprehensive error prevention system, one of the most important links is the terminal lock. At present, most of these industrial locks use toothed key locks, which have complex structures and many problems; if the lock cylinder is displaced during use, The insertion and removal of the key lock cylinder is not smooth; or the structure of the lock cylinder is too simple, resulting in staggered opening; thus, due to the poor safety and reliability of the locks used, the control is simple, and there is no group management function or working status detection function. It causes locks to be staggered and opened by mistake, resulting in failure and loss, and it is not easy to track and trace after the event. There is an urgent need for an industrial-grade lock with multiple management functions that is different from the previous structure.
