Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention will be further described:
Refer to Fig. 1 to Fig. 3, the Light-control door lock system that the present invention is based on multiple spot triggering comprises key 1 and door lock 2.Described key 1 is in cylindrical shape, and it comprises password setting unit 11, microprocessor unit 12, driver element 13, luminescence unit 14 and powered coupling unit 15.Described password setting unit 11 is for inputting encrypted message, and it can be button or touch-screen etc.The information that described microprocessor unit 12 sends for receiving password setting unit 11, and form 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 luminescence unit 14 to launch the light signal containing information under the control of level modulated signals.
Described luminescence unit 14 is provided with some pointolites 141 being positioned at described key 1 end surface, and the light signal launched between described pointolite 141 is different, and namely the instruction of described different pointolites 141 transmission is different.In the present embodiment, described pointolite 141 is light emitting diodes, and it constantly carries out sudden strain of a muscle at a high speed and goes out under the driving of driver element 13, and form the light signal representing 0 and 1 signal, described light signal is as the unlock instruction of key 1.Described light emitting diode is semiconductor light emitting light source, and not only brightness is high, reliability is high, energy loss is low, size is little, environmental protection, has more that modulating performance is good, response sensitivity advantages of higher.Described powered coupling unit 15 can be the various interface, the electric capacity or inductance etc. for generation of electric energy that can be used for being connected with outside, in the present embodiment, described powered coupling unit 15 is the female mouths of Mini USB, the female mouth of described Mini USB is positioned at the end of described key 1, and is electrically connected with described password setting unit 11, microprocessor unit 12 and driver element 13.Not only volume is little for the female mouth of described Mini USB, and is convenient to expansion.
Refer to Fig. 3 and Fig. 4, described door lock 2 comprises power supply coupling unit 21, power supply unit 22, photoelectric detection 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 matched with described key 1 size, described lockhole 28 internal fixtion has the described power supply coupling unit 21 for coordinating with the female mouth of described Mini USB, in the present embodiment, described power supply coupling unit 21 is the public mouth of Mini USB be electrically connected with described power supply unit 22.Described power supply unit 22 is 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 city.
Described photoelectric detection 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 passes the light signal of coming for receiving described key 1, and converts described light signal to current signal.Described voltage signal for converting described current signal to voltage signal, and amplifies by described modulate circuit unit 24.Described micro controller unit 25 controls described electric control lock main body 26 and described display unit 27 for the voltage signal exported according to described modulate circuit unit 24.Described electric control lock main body 26 can be made up of parts such as relay, motor and the dead bolts be connected with motor-driven, and described electric control lock main body 26 is prior art, does not repeat them here.The number of times that described display unit 27 opens for showing described door lock 2 or cuts out.
Principle of work of the present invention is: when described key 1 inserts the lockhole 28 of described door lock 2, and the male mouth of described Mini USB is connected with the female mouth grafting of described Mini USB, and the power supply unit 22 of door lock 2 is powered to described key 1 by the public mouth of described Mini USB.Described pointolite 141 and described photodetector 231 position one_to_one corresponding.Described key 1 to obtain after electricity just by described pointolite 141 to described photodetector 231 utilizing emitted light signal, described light signal converts current signal to through photoelectric detection 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.Normal data is stored in described micro controller unit 25, when described micro controller unit 25 receives after described key 1 passes the data of coming, by this decoding data, then the normal data in the data of decoding formation and micro controller unit 25 is contrasted.
If the normal data in micro controller unit 25 and decoded data match, then described micro controller unit 25 controls described electric control lock main body 26 and carries out unlocking action, simultaneously described micro controller unit 25 counts described unlocking action, and controls described display unit 27 according to the number of times of described unlatching and show the number of times that described electric control lock main body 26 opens altogether in this day.According to described prompting, user can judge whether someone opened and changed described password to door lock 2, thus can improve theftproof performance and more humane.
If decoded data are not mated with the normal data stored in micro controller unit 25, then judge whether described data are new code datas, if this code data is then replaced original normal data by new code data, and these data are kept in micro controller unit 25 as normal data, if not new code data, then described data are abandoned.
Insert after door lock 2 could work because described key 1 only has, thus have good confidentiality, information of unblanking not easily is replicated.The random corresponding described photodetector 231 of multiple pointolite 141, ensure that unique correspondence of key 1 and door lock 2, and contains much information.Due to the lockhole 28 internal environment relative closure of door lock 2, be therefore disturbed also little, the light intensity of needs is not high, without the need to high-power drive circuit, saves the space of key 1 internal hardware circuit design.
In sum, the Light-control door lock system that the present invention is based on multiple spot triggering is powered to key 1 by door lock 2, without the need to the battery of installing for providing electric energy in key 1, thus not only avoid the frequent situation changing key 1 battery, and reduce 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 is only schematic, instead of it is restrictive, those of ordinary skill in the art is under enlightenment of the present invention, do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, such as, give another secret spoon by the male mouth of described Mini USB and the female oral instructions of described Mini USB, improve security further; Or described power supply coupling unit 21 is all inductive coils with described powered coupling unit 15, described powered coupling unit 15 realizes obtaining energy etc. by induction, and these all belong within protection of the present invention.
