Description

Remote centralized control wireless remote control electronic lock system

technical field

The utility model belongs to the technical field of cabinet access control in a substation machine room, in particular to a remote centralized control wireless remote control electronic lock system.

Background technique

With the continuous improvement of power automation and informatization, more and more substations have become unattended substations. Under normal operating conditions, all equipment in the substation operates automatically. Only when manual participation is required for equipment operation, setting modification, and routine equipment inspection and maintenance, will someone go to the substation to work.

Misoperation of electrical equipment in substations has always been a common concern of people. However, misoperation accidents still occur in power systems. This not only caused casualties of operators, but also caused serious damage to electrical equipment and large-scale power outages in the power grid, which brought huge losses to the national economy. the

There are many cabinets in the computer room of the substation, and many important communication equipment and monitoring equipment are installed in the cabinet. During the daily maintenance and operation of various equipment, there are many people entering and leaving the substation, and there is no effective means for the cabinet access control in the computer room. Unrelated personnel can open any cabinet at will, and can perform arbitrary operations on the equipment in the cabinet intentionally or unintentionally. Once misoperation is performed, safety production accidents may occur. At the same time, there are also great security risks.

Therefore, it is necessary to comprehensively apply various new communication technologies and control technologies to develop a new type of lock control device for remote monitoring and management of cabinet doors in substations. By adding remote and manageable physical isolation measures, various equipment cabinets inside the substation can be effectively and safely isolated to prevent illegal and unauthorized intrusion or destruction, and remote control of effective access to equipment using various cabinets can achieve all-weather Continuous monitoring of all sensitive devices.

Contents of the invention
