New Type Substation Intelligent Cabinet Lock Scheme
As the carrier of electrical products, the cabinet in the mechanical structure provides installation, support, connection, protection, decoration, and other functions for the protection and measurement, and control equipment in the substation station. As the cabinet door lock, it is an indispensable part of the cabinet door and is used to protect equipment and personnel.
However, the traditional mechanical cabinet door lock has its shortcomings:
1. The mechanical cabinet door lock’s ability to prevent technical opening is very poor. Regardless of the structure of the mechanical cabinet door lock, it can be opened by other means, and the key can be copied and there is a great security risk.
2. At present, in substations, the cabinet locks and keys provided by the same equipment manufacturer are generally the same. This type of key can be used with all cabinet locks provided by this manufacturer, which invisibly lays hidden dangers for misoperation by operators.
In response to the above-mentioned defects, the new cabinet lock solution developed and produced by JWM has changed the traditional mechanical key management into password and authority management in field applications: effectively enhancing the safety of substation protection and measurement and control equipment, and realizing construction for operation and maintenance personnel The effective management of the operation has raised the demand for internal management of the power system and ensured the reliable operation of the equipment in the station.
This smart passive electronic cabinet lock does not have a power supply installed in the lock itself, so that wiring operations are avoided. The power supply is set on the key to avoiding frequent maintenance of the lock.
So, how does the cabinet lock achieve safe unlocking? There are two ways to unlock the cabinet lock. One way is to make an appointment to authorize unlocking, and the other way is to use a mobile phone to authorize unlocking. Appointment to authorize unlocking: When an employee has an unlocking task, he needs to obtain the smart key in advance. At this time, the administrator will give the key the unlocking authority for a certain period of time. The employee can then use the key to open all cabinet locks within the authority. After returning the key Relevant data will be recorded and documented. Mobile phone authorization unlocking: The employee uses the mobile phone APP to initiate an unlock request, and the administrator will authorize the unlocking in the background. After obtaining the unlocking permission, the passive electronic lock will be opened to complete the entire unlocking process.
JWM’s intelligent electronic passive cabinet lock, no matter what method is used to unlock, it needs to be authorized by the administrator, otherwise, it cannot be unlocked. This is also the advantage of the intelligent cabinet lock. The smart passive cabinet lock uses a hexadecimal 12-digit code, three-layer password, and protocol protection, and cannot be cracked at present; in the case of a lost key, the administrator can delete it in the background, even if someone else finds the key. unlock. And has the effect of waterproof and dustproof, completely suitable for outdoor installation applications.
