Description
Technical field
The invention belongs to electric power power transmission and transformation technical field, be specifically related to a kind of skeleton key that needs password authorization.
Background technology
Stop sending in the grid switching operation of electricity at power system transformer substation equipment, for fear of the electric grid large area power cut accident occurs because of the artificial origin, need the perfect operating process of a cover, the order of each grid switching operation is fixed, in order to prevent this order because mistake appears in artificial reason, administrative authority has designed a cover barring program specially for this order, and when not finishing previous action, technical assurance can not be carried out next step operation.
In order to prevent that operating personnel from operating in proper order not according to set operating process, use the skeleton key operation to cause power grid accident, administrative authority to take some ways that skeleton key is managed without authorization, generally there are following two kinds:
First kind: only work out management system,, rely on operator on duty's sense of responsibility and the consciousness of subjecting oneself to control with the nonvoluntary use skeleton key of system restriction operator on duty.This method can not be monitored the operating position of skeleton key.
Second kind: make or other materials is made a box of wood, be closed with lead sealing or administrative authority strip of paper used for sealing with an official seal affixed, lead sealing and strip of paper used for sealing are got to administrative authority by transformer station, open lead sealing or strip of paper used for sealing during use, seal again after using.This method has adopted some technological means that skeleton key is managed, but remains in following problem: one, and lead sealing can be bought, and administrative authority can not the working control usage quantity; They are two years old, because transformer station is generally all far away apart from administrative authority, managerial personnel's inspection that exercises supervision of can not often arriving at a station, the person on duty is after using skeleton key, may skeleton key not continued to put back to box, so that oneself can at will use, only before administrative authority checks, key is put back to, the operating position of skeleton key is also uncontrollable like this; Its three, the statistics of lead sealing and strip of paper used for sealing, the record comparatively the trouble, transformer station is too many, when arriving at a station, managerial personnel can not check out this station how many lead sealings and strip of paper used for sealing on earth, in addition, there are the problem of losing or damaging in lead sealing and strip of paper used for sealing, use that can not the better controlled skeleton key.From crash analysis result in the past, the unlocking operation that violates the rules occupies higher ratio.So to the more imperfect all the time management method of skeleton key, have some hidden danger, have the possibility that maloperation takes place.
Summary of the invention
In order to overcome the managerial defective of above-mentioned skeleton key, the utility model provides a kind of skeleton key that needs password authorization, can carry out the authorization management to the various skeleton keys in transformer station, the generating plant anti-misoperation locking device, and the automatic accurate recording user various information of taking out and giving back skeleton key, accomplish security management and information system management that skeleton key is used.
For achieving the above object, the technical solution used in the present invention is: the skeleton key of this need password authorization, have handle and the key body that is fixed on the handle, it is characterized in that: described key body is provided with bayonet lock, bayonet lock is positioned in the endoporus on the key body, be provided with the topworks that the control bayonet lock stretches out the withdrawal action in the key body, described handle is a box body, be provided with control and treatment circuit in the box body, box body top control panel, described control and treatment circuit is by microprocessor, communication module, the liquid crystal display module, storage chip, radio-frequency module, electric source monitoring circuit, clock chip, the keyboard chip, control circuit for electromagnet, reset circuit is formed, communication module, the liquid crystal display module, storage chip, radio-frequency module, electric source monitoring circuit, clock chip, the keyboard chip, control circuit for electromagnet, reset circuit is connected with microprocessor by bus respectively; Described box body top control panel is provided with the radio frequency card reader/writer of radio-frequency module control, the operation keyboard of keyboard chip controls; Described topworks has and is positioned at box body and by electromagnet, operating rod and operating rod back-moving spring by control circuit for electromagnet control adhesive, operating rod passes the bottom that the interior endoporus other end of key body stretches into bayonet lock, the end of operating rod is a cam, the other end of operating rod has the lug by the electromagnetic actuation upset, and bayonet lock is supported by the indentation spring and makes it contact cam all the time.
But described microprocessor also has the power connector end that is used for the serial ports link external AC power supply that is connected with host computer.
Described radio frequency card reader/writer adopts non-contact radio-frequency IC-card card reader/writer.
Adopt the beneficial effect of technique scheme to be: the skeleton key of this need password authorization is made up of box body handle that constitutes and the key body that is fixed on the box body, key body is provided with bayonet lock, be provided with by microprocessor in the box body handle, communication module, the liquid crystal display module, storage chip, radio-frequency module, electric source monitoring circuit, clock chip, the keyboard chip, control circuit for electromagnet, reset circuit is formed, communication module, the liquid crystal display module, storage chip, radio-frequency module, electric source monitoring circuit, clock chip, the keyboard chip, control circuit for electromagnet, the authorisation process control circuit that reset circuit constitutes.Above-mentioned each functional module, chip, circuit all adopt prior art.When this skeleton key was not authorized, the bayonet lock on the key body was in and stretches out the outer position of key body, because the existence of bayonet lock, this skeleton key is inserted and do not advanced in the lockhole lockset of not opening.After the control and treatment circuit mandate by when using skeleton key of the present invention, the user uses operation keyboard the skeleton key controller to be transferred to the state of gathering user's radio-frequency (RF) IC card, radio-frequency (RF) IC card is put into radio-frequency (RF) IC card card reader/writer induction zone, the radio-frequency (RF) IC card card reader/writer is gathered user profile to the radio-frequency (RF) IC card Card Reader, promptly with radio-frequency (RF) IC card as the subscriber authorisation instrument, be verified be validated user after, radio-frequency module transmission information is given microprocessor, through after the microprocessor processes, the work of control control circuit for electromagnet, the control electromagnetic actuation, drive in topworks's motion action bayonet lock withdrawal key body, this skeleton key can be unblanked, thereby network system is operated.Microprocessor can be noted this operation automatically.The serial ports link of microprocessor is with after host computer is connected, and microprocessor can import unlock operation information into and carry out storage administration on the host computer after record automatically takes out at every turn and gives back key.Compared with prior art, with radio-frequency (RF) IC card as the mandate instrument, after skeleton key of the present invention operated, this skeleton key could use, reliability height, convenient management, but the accurate recording user takes out, gives back the time, reason, operation key of key, Approved by information, and record in detail accurately.Security management and information system management that skeleton key is taken have been realized accomplishing.
