Description
Technical field
The present invention relates to the distant place approval apparatus of the anti-error lockset of a kind of electric substation, belong to electric substation five anti-microcomputer lock technology fields.
Background technology
Along with the electrical network develop rapidly, equipment rolls up in the electric substation, though can help operation, maintainer to differentiate the identification various device through marking dual title, mistakenly entering charged chamber, misoperation grid equipment still happen occasionally.
In order to avoid the generation of these accidents more reliably, adopt the anti-misoperation locking mode of " observing and controlling interlocking+electrical interlock " at present.But the operating handle for all kinds of mechanism cases, terminal chamber door and manual handling equipment in the electric substation also fails to adopt effective anti-misoperation locking technological means.
Though five anti-microcomputer locks can effectively have been avoided the generation of equipment misoperation fault, management is to adopt 10 codings for lockset, therefore has only 1024 kinds of permutation and combination, so there are two drawbacks at present: 1, number of devices in the electric substation is placed restrictions on to some extent.Number of devices surpasses 1024 in an electric substation, and the lockset coding will duplicate, and brings great potential safety hazard to handling safety; 2, only can control an electric substation.Owing to can only control, cause the distinct device of different electric substations to produce looks coding together to an electric substation.If the maintainer will be at a plurality of electric substations sex work in batches such as scarce of making an inspection tour successively, disappear, the operations staff must follow the maintainer always, carries out the permission of computer key at the scene, wastes operations staff's time and efforts greatly.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructurely, easy to operate, can improve the distant place approval apparatus of the anti-error lockset of electric substation of security reliability.
The present invention is that the technical scheme that achieves the above object is: the distant place approval apparatus of the anti-error lockset of a kind of electric substation; Comprise that each lockset in the electric substation is to be useful on the computer key of opening each lockset; It is characterized in that: be attached with each self-corresponding radio frequency recognizing electronic label on said each lockset, and each radio frequency recognizing electronic label has independent separately lockset coding; Described computer key comprises the battery that is used to provide working power, be used for to input signal identification and contrast and control arm processor, be used to read card reading module, real-time clock module, LCD display module, information storage module and communication module and the latch actuation module of lockset coding on the electronic tag; Battery is connected with the latch actuation module with card reading module, real-time clock module, LCD display module, information storage module and communication module respectively; The logical radio frequency of card reading module is crossed antenna and radio frequency recognizing electronic label communication; The communication module that is connected on the arm processor PORT COM is connected with host computer, and LCD display module, information storage module and real-time clock module are connected with the arm processor input/output end port respectively with the latch actuation module.
A distant place of the present invention approval apparatus adopts radio-frequency technique; On each lockset, be attached with each self-corresponding radio frequency recognizing electronic label; Make each radio frequency recognizing electronic label have independent separately lockset coding; And computer key comprises arm processor, card reading module, real-time clock module, LCD display module, information storage module and communication module and latch actuation module; Read the lockset coding of unique establishment on the radio frequency recognizing electronic label through card reading module, and arm processor is connected with host computer through communication module, can be through the host computer information of unblanking that secures permission; Make the information storage module storage obtain permitting the information of unblanking; Permission is simultaneously unblanked information through the instant playback of LCD display module, and unblank lockset coded message on information and the radio frequency recognizing electronic label of the permission that arm processor will obtain is compared and judged that the License Info of unblanking is denied effective, and only the arm processor input control signal makes the work of latch actuation module when the License Info of unblanking is effective; Utilize the mechanical latching of lockset to realize the equipment release and unblank, five anti-locksets are carried out release.Information storage module of the present invention can write down the unblank key message and the power down information such as uncaging time, release personnel and permission personnel of each step of information of permission, shows the permission information of unblanking in real time through the LCD display module simultaneously, conveniently reminds and reviews.The present invention adopts radio frequency recognizing electronic label; The lockset coding is set up unique corresponding relation with lockset actual installation position; Through unique coding in the coded electronic realization on a large scale; Solved the lockset coding and repeated to bring great potential safety hazard, be implemented in a distant place can be carried out the key decoding simultaneously to any apparatus in the electric substation permission to handling safety.Perfect in shape and function of the present invention, extensibility is strong, can let the operations staff carry out distant place permission; Allow to open certain anti-error lockset of certain electric substation, perhaps allow to open many groups of anti-error locksets of a plurality of electric substations, guaranteeing to alleviate operations staff's labor intensity on the safe and punctual basis; Perfect in shape and function; Security reliability is good, and integrated level is high, satisfies on-the-spot user demand.
