Key permission is excessive, the high problem of maintenance safety risk.
The technical solution of the utility model is: a kind of isolation examination and repair system, including five anti-hosts, the isolation examination and repair system
Further include that Intelligent key and five are anti-lock, five anti-hosts include key production module and host computer communication module, key production module and
Host computer communication module communication connection, Intelligent key include key memory module and key communication module, key memory module and key
Spoon communication module electrical connection, five it is anti-lock include deciphering module, action module and five anti-lock communication modules, deciphering module and movement mould
Block, five anti-lock communication module electrical connections, host computer communication module and key communication module communication connection, host computer communication module and five are prevented
Lock communication module electrical connection, key communication module and five anti-lock communication module communication connections.
Preferably, the key production module is hash algorithm key generator, and the public key that key production module generates is deposited
In five anti-lock memory modules, the private key that key production module generates is stored in key memory module for storage.
Preferably, the host computer communication module and the communication connection mode of key communication module are connect using RS485 or RS232
Port communications.
Preferably, the key communication module and five anti-lock communication module communication connection modes use infrared communication.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by using five anti-host assignment keys, Intelligent key and five anti-lock points
Not Chu Cun five anti-host assignments key, by five it is anti-lock in deciphering modules whether judge the key stored in Intelligent key
With the cipher key match of five anti-lock interior storages, the control of intelligent key unlocking permission is realized with this.The utility model structure is simple, peace
Quan Xinggao is particularly useful for electrical equipment isolation examination and repair system.
Detailed description of the invention

Key production module be five anti-hosts 1 in program, host computer communication module include ethernet interface, RS232 interface or
The data of RS485 interface etc., key production module and host computer communication module communication connection, key production module can be logical by host
Letter module is sent；Intelligent key 3 includes key memory module and key communication module, and key memory module and key communicate
Module is connected by conducting wire or circuit board；Five anti-lock 2 include deciphering module, action module and five anti-lock communication modules, decrypts mould
Block can be general microprocessor, and action module can be common electric signal drive actions machine in the five-preventing systems such as electromagnetic lock
Structure, deciphering module are connect with action module, five anti-lock communication modules by conducting wire or circuit board；Host computer communication module and key are logical
Believe that module is connected by RS232 interface or RS485 interface, host computer communication module and five anti-lock communication modules can pass through Ethernet
Interface connection, key communication module can be connect with five anti-lock communication modules by infrared communication.Pass through in five anti-lock 2 when use
Deciphering module come judge the key stored in Intelligent key 3 whether with five anti-lock 2 in the cipher key match that stores, intelligence is realized with this
Energy key 3 unlocks the control of permission.
Preferably, the key production module is hash algorithm key generator, and the public key that key production module generates is deposited
In five anti-lock memory modules, the private key that key production module generates is stored in key memory module for storage.Using hash algorithm
Key is generated, safety is higher.
Preferably, the host computer communication module and the communication connection mode of key communication module are connect using RS485 or RS232
Port communications.RS485 or RS232 interface are the common interfaces of universal computer, easy to use.
Preferably, the key communication module and five anti-lock communication module communication connection modes use infrared communication.It is infrared
Communication mode is the communication mode that existing five-preventing system uses, and directlys adopt infrared communication, improvement expenses are lower.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
