Embodiment
The present invention will be further described below in conjunction with drawings and the specific embodiments:
See also Fig. 1 to Fig. 3, the light-operated door-locking system that the present invention is based on the multiple spot triggering comprises key 1 and door lock 2.Described key 1 is cylindrical shape, and it comprises that password arranges unit 11, microprocessor unit 12, driver element 13, luminescence unit 14 and is subjected to electric coupling unit 15.Described password arranges unit 11 and is used for the input encrypted message, and it can be button or touch-screen etc.Described microprocessor unit 12 is used for receiving password the information that unit 11 sends is set, and forms coded data according to described information.Described coded data is stored in the storer (not shown) of described microprocessor unit 12, and described microprocessor unit 12 is according to described coded data transmission level modulation signal.Described driver element 13 drives the light signal that luminescence unit 14 emissions contain information under the control of level modulation signal.
Described luminescence unit 14 is provided with some pointolites 141 that are positioned at described key 1 one end surfaces, the light signal difference of emission between the described pointolite 141, i.e. the instruction difference that sends of described different pointolite 141.In the present embodiment, described pointolite 141 is light emitting diodes, and its sudden strain of a muscle of constantly carrying out high speed under the driving of driver element 13 is gone out, and forms the light signal that represents 0 and 1 signal, and described light signal is as the unlock instruction of key 1.Described light emitting diode is the semiconductor light emitting light source, not only brightness height, reliability height, energy loss is low, size is little, environmental protection, has more that modulating performance is good, the response sensitivity advantages of higher.It is described that to be subjected to electric coupling unit 15 can be the various interfaces that can be used for being connected with the outside, for generation of the electric capacity of electric energy or inductance etc., in the present embodiment, the described electric coupling unit 15 that is subjected to is female mouthful of Mini USB, described Mini USB is positioned at the end of described key 1 for female mouthful, and with described password unit 11, microprocessor unit 12 and driver element 13 is set and is electrically connected.Female mouthful not only volume is little for described Mini USB, and is convenient to expansion.
See also Fig. 3 and Fig. 4, described door lock 2 comprises power supply coupling unit 21, power supply unit 22, photodetection unit 23, modulate circuit unit 24, micro controller unit 25, electric control lock main body 26 and display unit 27, described door lock 2 is provided with the lockhole 28 that is complementary with described key 1 size, fixedly be useful on the described power supply coupling unit 21 that cooperates with the female mouth of described Mini USB in the described lockhole 28, in the present embodiment, described power supply coupling unit 21 is the public mouth of Mini USB that is electrically connected with described power supply unit 22.Described power supply unit 22 is used for providing electric energy to described door lock 2, and it can be battery or the change-over circuit that can be electrically connected with the city.
Described photodetection unit 23 is provided with some photodetectors 231, and described photodetector 231 is arranged on the hole wall of described lockhole 28.Described photodetector 231 is used for receiving described key 1 and passes the light signal of coming, and converts described light signal to current signal.Described modulate circuit unit 24 is used for converting described current signal to voltage signal, and described voltage signal is amplified.Described micro controller unit 25 is used for controlling described electric control lock main body 26 and described display unit 27 according to the voltage signal of described modulate circuit unit 24 outputs.Described electric control lock main body 26 can reach the parts such as dead bolt that are in transmission connection with motor by relay, motor and constitute, and described electric control lock main body 26 is prior art, does not repeat them here.Described display unit 27 is used for showing described door lock 2 unlatchings or the number of times of cutting out.
Principle of work of the present invention is: when described key 1 inserted the lockhole 28 of described door lock 2, the public mouth of described Mini USB was pegged graft with described Mini USB mother mouth and is linked to each other, and the power supply unit 22 of door lock 2 is powered to described key 1 by described Mini USB public affairs mouth.Described pointolite 141 is corresponding one by one with described photodetector 231 positions.Described key 1 is just launched light signals by described pointolite 141 to described photodetector 231 after obtaining electricity, described light signal converts current signal to through photodetection unit 23, and described current signal is reduced into original signal and inputs to described microprocessor unit 12 after described modulate circuit converts voltage signal to and amplifies.Store normal data in the described micro controller unit 25, when described micro controller unit 25 receives after described key 1 passes the data of coming, these data are decoded, and the data of the formation of will decoding then and the normal data in the micro controller unit 25 compare.
If normal data and decoded data in the micro controller unit 25 are complementary, then the described electric control lock main body 26 of described micro controller unit 25 controls is carried out unlocking action, 25 pairs of described unlocking action of described micro controller unit are counted simultaneously, and control the number of times that the described electric control lock main body 26 of described display unit 27 demonstrations was opened altogether in this day according to the number of times of described unlatching.The user can judge according to described prompting whether the someone opened and the described password of replacing door lock 2, thereby can improve theftproof performance and more humane.
If the normal data of storage does not match in decoded data and the micro controller unit 25, judge then whether described data are new code datas, if new code data is then replaced original normal data with this code data, and these data are kept in the micro controller unit 25 as normal data, if not new code data, then described data are abandoned.
Because described key 1 could be worked after having only the door lock 2 of insertion, thereby has good confidentiality, the information of unblanking is difficult for being replicated.A plurality of pointolites 141 are corresponding described photodetector 231 at random, has guaranteed unique correspondence of key 1 and door lock 2, and has contained much information.Because therefore the lockhole 28 internal environment relative closures of door lock 2 are subjected to interference also little, the light intensity that needs is not high, need not high-power drive circuit, has saved the space of key 1 internal hardware circuit design.
In sum, the light-operated door-locking system that the present invention is based on the multiple spot triggering gives key 1 power supply by door lock 2, need not to install the battery be used to electric energy is provided in the key 1, thereby not only avoided the situation of frequent replacing key 1 battery, and reduced the volume of key 1, be easy to carry and use, more humane.
By reference to the accompanying drawings embodiments of the invention are described above, but the present invention is not limited to above-mentioned embodiment, above-mentioned embodiment only is schematic, rather than it is restrictive, those of ordinary skill in the art is under enlightenment of the present invention, do not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, for example, give another secret spoon by public mouthful of described Mini USB and the female oral instructions of described Mini USB, further improve security; Or described power supply coupling unit 21 all is inductive coils with the described electric coupling unit 15 that is subjected to, and the described electric coupling unit 15 that is subjected to is realized obtaining energy etc. by induction, and these all belong within the protection of the present invention.
