A light control detection device for the state of a lock

Abstract

The invention provides a status light-control detection device for locksets. The status light-control detection device comprises a smart key and a lock cylinder, the lock cylinder consists of a lock cylinder shell and an inner lock cylinder, and the inner lock cylinder comprises a rotating lock cylinder and a fixed lock cylinder. A power module, a light source transmission module and a light source receiving module are arranged in the smart key. When an unlocking shaft of the smart key is inserted into the lock cylinder to unlock, an axial light source emitted by the light source transmission module penetrates through the rotating lock cylinder to reach the fixed lock cylinder and bi-directionally reflected or guided back by a double-light-source directional portion of the fixed lock cylinder, then the light source receiving module receives two light sources at the same time, and a status of key insertion for unlocking is reflected. When the unlocking shaft drives the rotating lock cylinder to rotate by a certain angle to unlock the lock cylinder, the axial light source emitted by the light source transmission module penetrates through the rotating lock cylinder to reach the fixed lock cylinder and regularly reflected or guided back by a single-light-source directional portion of the fixed lock cylinder, and then the light source receiving module receives one light source to store and record lock cylinder unlocking status information of the smart key.

Description

[0001] 【Technical field】 [0002] The invention relates to a lock in an industrial error prevention system, in particular to a state optical control detection device for a lock. [0003] 【Background technique】 [0004] At present, many electric power, energy, industrial and mining enterprises have strict management procedures for the management and operation of equipment. It is not uncommon to see cases of major accidents due to non-compliance with operating procedures. In order to overcome this problem, comprehensive error prevention management is generally adopted. protection system. [0005] In the underlying protection of the comprehensive anti-malfunction system, one of the most important links is the terminal lock, especially the substation switch cabinets, terminal boxes, power supply boxes and other equipment in the power industry, most of which are managed by old-fashioned mechanical locks. Even without lock management, due to the large number of cabinet doors and dif...

Problems solved by technology

Although the radio remote control lock of the wireless access control system is convenient to operate, the radio remote control lock mainly adopts radio frequency technology, and the transmitted radio signal is easily intercepted and copied by electromagnetic interference, resulting in leakage of unlocking information, so its security is not high

[0006] In addition, 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

However, in the actual implementation process, many operators often ignore the rules and regulations and do not follow the regulations, resulting in risky accidents

A major link, because the locks used are poor in safety and reliability, and do not have the function of detecting the working status of unlocking and locking, causing the locks to be staggered and opened by mistake, resulting in failures and losses, and it is not easy to track and trace afterwards
