Abstract
A non-contactor anti-error-lock computer key comprises a computer key body (3) and a non-contactor detector (4) mounted on the computer key body (3), while the non-contactor detector does not contact a wireless code sheet when pickups code. The utility model uses wireless method to pickup code to effectively avoid the mechanical structure of the detector being clamped and bad mechanical contact, while the code values can not be differed via mechanical shapes to avoid artificial code value simulation. The code value picked by the non-contactor detector is digit code, to effectively avoid limited code number. The utility model can effectively avoid error operation, with wide application on the breaker and insulation switches or the like, in anti-error-operation transformer (station), power plant or the like.
Description
Technical field
The utility model relates to a kind of computer key, especially a kind of computer key of electric anti-misoperation locking device.Locksets such as the utility model and wireless anti-error mechanical coding lock, wireless anti-error electric coding lock are used, be the part of the electric anti-misoperation locking device in electric substation's (station), the power plant's (station) etc., be mainly used on the equipment such as preventing interior circuit breaker such as misoperation electric substation (station), power plant's (station), isolating switch.
Background technology
At present, in micro_computer five_proof locking field, the used computer key of anti-misoperation locking device is adopted the main mechanical probe that adopts of sign indicating number to field apparatus, the structure of this computer key as shown in Figure 1, the chip structure corresponding with it is as shown in Figure 2.The bossing 7 that several can be movable is arranged, these projectioies and can movable part be used to gather the code value of corresponding chip 8 on the mechanical probe 6 of this computer key 5.When computer key 5 need be adopted yard, computer key 5 insertions are equipped with in the lockset of chip 8, at this moment, one or several bossing is pushed down respective protrusions part 7 on the mechanical probe 6 of computer key 5 on the chip 8, and respective protrusions part 7 on the mechanical probe 6 depressed, make the electrical contact conducting or the disconnection that link to each other with mechanical probe 6, computer key 5 obtains the coding of equipment by the number of electrical contact conducting or disconnection.There is following drawback in this coding mode of adopting owing to its intrinsic architectural characteristic:
At first, there are loose contact, phenomenon such as stuck, make that to adopt sign indicating number inaccurate, and damage easily.For example: under the adverse circumstances such as, humidity more, cause loose contact easily, shorten the useful life of mechanical probe 6 at dust.
Next, the artificial easily imitation of chip 8 codings, operating personnel can press the mechanical probe 6 on the computer key 5 according to the code value of on-the-spot chip 8, imitate the actual yard process of adopting, and cause misoperation, therefore have major safety risks.
Moreover because the restriction of mechanical dimension, group/cording quantity is limited.Along with the raising of comprehensive automation of electric power system degree, the application of micro_computer five_proof concentrator station is also more and more, and the quantity of device coding is also increasing thereupon, more than adopts sign indicating number, coded system is difficult to satisfy this ever-increasing demand.
This practical fresh content
The utility model is in order to overcome above-mentioned shortcomings and deficiencies, a kind of contactless anti-misoperation locking computer key is provided, this utility model is replaced with contactless probe to the mechanical probe that is used to adopt sign indicating number in the prior art, and the corresponding with it chip that is installed on the lockset is a kind of Wireless code sheet.This coding mode of adopting can prevent misoperation effectively, and has solved defective described in the prior art and drawback.
The utility model takes following technical scheme to realize: the utility model comprises computer key main body, contactless probe, and contactless probe is contained on the computer key main body.Contactless probe comprises wireless transmission and wireless receiving circuit, and the computer key main body comprises the main body circuit.Contactless probe is adopted sign indicating number wirelessly, and send the main body circuit to handle the information that collects.Contactless detecting head surface does not have several protruding parts, and when adopting yard, contactless probe and Wireless code sheet on it does not have Mechanical Contact, is to adopt sign indicating number by wireless mode.
Because this utility model is noncontact when adopting yard, thereby the mechanical structure that can effectively prevent to pop one's head in is blocked the problem bad with Mechanical Contact; The code value of probe collection that the utility model is contactless is a digital coding, has effectively overcome the restricted drawback of group/cording quantity; The utility model is wireless when adopting yard, can't distinguish code value from the mechanical profile of contactless probe, thereby can not manually imitate code value, thus the generation of the phenomenon of effectively having stopped to practise fraud.
