Description
Technical Field
The utility model relates to a computer management field of mistake and lock crowd is prevented in electric power safety, especially a computer key that is used for mistake and lock crowd management is prevented to electric power computer.
Background
At present, as is known in the art, in the field of electric power safety anti-misoperation, a microcomputer anti-misoperation system which is already disclosed and used in maturity is a microcomputer anti-misoperation system based on a double-handle mode computer key developed in the early nineties, and the microcomputer anti-misoperation system is basically characterized in that:
the lock consists of an upper computer, simulation management software, a signal transmission device, a computer key, a mechanical padlock and a five-prevention fixed lock which are matched with the computer key and provided with a lock code and a universal anti-dialing lock cylinder, and an electric lock which is provided with a lock code and consists of two electrode columns which can be matched and contacted with the electrodes of the computer key.
The microcomputer anti-misoperation system is characterized in that: the tool to lock kind is few, mechanical tool to lock primary equipment of shutting electric power, electric lock shutting control electrical return circuit, and the tool to lock generally needs to possess prevents dialling the function in order to prevent that operating personnel from dialling the formula and unblanking. Special anti-theft features are generally not required and the lock cylinder is generally a relatively simple twist-lock cylinder to ensure adequate reliability and reduce manufacturing and use costs. The computer key related identification lock code and the unlocking mechanism are matched with the lockset. In the field of microcomputer error prevention, a double-handle double-computer key is used at the initial stage, and then a single-handle bipolar type computer key for preventing errors of a power microcomputer, which is suitable for the use habit of people, is developed through the efforts of experts;
on the other hand, in a substation, besides many primary devices need to be managed through locks of the microcomputer anti-misoperation system, there are also many places where non-primary devices need to be locked by the locks, such as ladder guard rails, terminal boxes, control screen cabinet doors, access doors, fire-proof isolation doors, floor security doors, equipment room doors, safety equipment room doors and other various office or conference room doors. These locks are characterized by being locked by means of padlocks or fixed locks of various types, such as padlocks, handle locks, cabinet locks, lever locks, fire-resistant locks, security locks, ball locks, etc. These locks are characterized in that: a high anti-theft feature is required to prevent the door lock from being easily opened to cause loss.
The door locks form a group of lock groups. In order to solve the conventional trouble of requiring a series of mechanical keys for unlocking, people think of methods, such as management by adopting a mechanical universal lock cylinder. Or further, each lock is provided with a lock code, an original microcomputer error prevention system management mode is adopted for cutting, and a lock group control system is designed on the basis of a single-handle computer key and a corresponding lock and comprises an upper computer, management software, a signal transmission device, a computer key and a lock. For example, the electric power security intelligent lock control system with patent number 201010131690.6 applied on 3/22/2010 and the electric control intelligent key for the magnetic coding lock with patent number 201019050039.3 applied on 11/02/2010 can be seen that the lock group control is characterized in that: the identity recognition and the opening range recognition of the opened lock are realized. But generally without strict chronological requirements. At the same time, the anti-theft characteristic of the lock core is high, and because the opening frequency of the doors is high, the reliability, the durability and the anti-theft characteristic of the locks of the lock group are equal to the level of the civil door lock.
According to the current situation, if both a microcomputer anti-misoperation system and a lock group control system are adopted, one substation worker is provided with two different computer keys during operation, and the management and maintenance of the substation worker are also two sets of systems, so that the user cost is increased and the maintenance and use are inconvenient, which is the biggest defect of the current computer key once two systems of a client are managed by a microcomputer.
The key point is that the lock adopts all anti-theft level lock cylinders, but the cost is increased; or the lockset respectively uses two lock cylinders, namely a door lock with high anti-theft characteristic and a microcomputer anti-misoperation five-prevention lockset only with anti-dialing characteristic are simultaneously adopted, and at the moment, the problem that a computer key has a related structure which can open the lockset in a microcomputer anti-misoperation system is solved.
