The explanation of Fig. 5:
Shown in ginseng Fig. 5, illustrate the primary structure of a kind of radio frequency guide-passage key, lock cylinder system 100 here, this system 100 principal character is as follows:
Radio frequency guide-passage key 200 forms primarily of key bar 210 and key handle 250.Described key bar 210 is fixedly connected with by inner side with key handle 250.Key bar 210 is arranged non-conduction circuit 220 structure with individual radio-frequency information, non-conduction circuit 220 structure arranges the radio frequency chip 240 with personal information, correspond to described radio frequency chip 240, be provided with the key tie point 230 in order to be connected with extraneous conductor.As shown in Figure 5, in radio frequency chip 240 lower end, conducting structure is utilized, be respectively arranged with key first tie point 231, key second tie point 232, these two tie points do not form conducting structure, and the first tie point 231 is annulus, and key second tie point 232 is the point in annulus.
Correspond to radio frequency guide-passage key 200, on radio frequency guide-passage lock core 300, be provided with can with the circuit on radio frequency guide-passage key 200 the corresponding lock core guide passage realizing conducting.Lock core guide passage is provided with the lock core guide passage tie point corresponding with key tie point 230.Lock core guide passage arranges lock core guide passage first tie point, lock core guide passage second tie point.Arrange the elastic device can upspring in lock core guide passage tie point front end in radio frequency guide-passage rear end, elastic device here adopts spring or flexure strip structure to implement.
For example and without limitation, a kind of radio frequency guide-passage key, lock cylinder system 100 are achieved in that as Fig. 5, utilize the non-conduction circuit 220 on radio frequency guide-passage key 200, can upspring in the front end of lock core guide passage tie point 320 by the elastic device on lock core guide passage, radio frequency guide-passage does not form conducting structure, now radio-frequency information does not externally send, and just effectively prevents outer locator to the detection of information, prevents the safety problems such as the information of user leaks outside.
When needing to enter designated room, radio frequency guide-passage key 200 is inserted radio frequency guide-passage lock core 300 inner, elastic device is compressed.This time, the key tie point 230 being connected with radio frequency chip 240 is connected with the lock core guide passage tie point being arranged at lock core inside, namely key first tie point 231 and lock core guide passage first tie point are conducted, key second tie point and the conducting of lock core guide passage first tie point, when whole key tie points 230 contacts with lock core guide passage tie point, the circuit turn-on on radio frequency guide-passage key.Such radio frequency chip 240 just externally sends signal, and carry out data cube computation with the radio-frequency probe at room entrances place, user also just can enter room.
That is, described lock core guide passage tie point 320, when key tie point 320 be both sides on key body arrange one respectively, equally also respectively establish corresponding position respectively to establish lock core guide passage tie point in the position of correspondence,
Are annulus at the first tie point of described key tie point 320, key second tie point is the point in annulus, and corresponding lock core guide passage tie point is the point in annulus and annulus.
The implementation method of radio frequency guide-passage key, lock cylinder system, the method includes following steps:
Step 1, makes radio frequency guide-passage key 200, and supporting radio frequency guide-passage lock core 300.
Radio frequency guide-passage key 200 forms primarily of key bar 210 and key handle 250.Described key bar 210 is fixedly connected with by inner side with key handle 250.Key bar 210 is arranged non-conduction circuit 220 structure with radio-frequency information, radio frequency chip 240 is set thereon.Meanwhile, correspond to radio frequency chip 240, the key tie point 230 in order to be connected with extraneous conductor is set.
Further, on radio frequency guide-passage lock core 300, being provided with can be corresponding with the circuit on radio frequency guide-passage key 200 and realize the lock core guide passage 310 of conducting, as the conductor part that circuit 220 non-conduction on radio frequency guide-passage key 200 lacks.Meanwhile, correspond to non-conduction circuit 220, lock core guide passage 310 arranges the lock core guide passage tie point 320 corresponding with key tie point 230.Lock core guide passage 310 is provided with lock core guide passage first tie point 321, lock core guide passage second tie point 322.Correspond to described lock core guide passage tie point 320, the elastic device 330 can upspring in lock core guide passage tie point 320 front end is set in radio frequency guide-passage 310 rear end.
Step 2, is inserted into radio frequency guide-passage key 200 in radio frequency guide-passage lock core 300.
When entering designated room, radio frequency guide-passage key 200 is inserted radio frequency guide-passage lock core 300 inner, the elastic device 330 on lock core guide passage 310 is compressed, and is compressed to and radio frequency guide-passage lock core 300 inside parallel position the front end of lock core guide passage tie point 320.
Step 3, the lock core guide passage tie point 320 in radio frequency guide-passage lock core 300 and the key tie point 230 on radio frequency guide-passage key 200 contact and are in the state of conducting.
Now, key tie point 230 is connected with the lock core guide passage tie point 320 being arranged at lock core inside, and namely key first tie point 231 and lock core guide passage first tie point 321 are conducted, key second tie point 232 and the conducting of lock core guide passage first tie point 322.
Step 4, the integrated circuit of the radio frequency chip 240 on radio frequency guide-passage key 200 is by not on-state to conducting state, and supporting identification data can occur radio frequency chip 240.
When whole key tie points 230 contacts with lock core guide passage tie point 320, radio frequency guide-passage key forms turning circuit.Such radio circuit externally sends signal, and carry out data cube computation with the radio-frequency probe at room entrances place, user also just can enter room.
Be more than the description of this invention and non-limiting, based on other embodiment of inventive concept, all among protection scope of the present invention.
