Abstract
The invention discloses a photoelectric password lock system. The system comprises an electric control lock, an optical code generating device, an optical code receiving device, a checking device and a control device. The optical code receiving device, the checking device, the control device and the electric control lock are connected into a whole for constituting a photoelectric password lock, wherein the optical code generating device is a portable device which can be carried about and is a photoelectric password key which can be matched with the photoelectric password lock for use. A password is generated by adopting a programmable chip for control, the number of bits of the password can be greatly expanded, and the cracking difficulty is increased in a transnormal manner. A password signal is transmitted through light, thus the possibility of illegally intercepting a wireless signal containing the password is effectively overcome.
Description
Technical field
The present invention relates to a kind of lockset, relate in particular to a kind of electric control lock of opening through photosignal control.
Background technology
Traditional electric control lock all is through the password key mode usually, like a lot of block of flats or the used door lock of community residential building.Another kind of mode commonly used is through wireless signal, like the electronic safety lock of most of vehicles.But the electronic lock that adopts above dual mode all exists drawback separately to have much room for improvement.The password key mode because the password limited bits is generally 9, is provided with simply, can stay the use vestige after long-term in addition the use, and more illegal user provides and cracked foundation.Though not existing, wireless mode do not use vestige and password setting simple question; But being wireless signal, the wireless maximum problem of mode of unblanking had the premeditaor to pass through special receiver intercepting and capturing easily; Through cracking and duplicating, just can the lockset safety of the wireless mode of unblanking be constituted a threat to again.
It is a kind of through optical signal transmission fiber that formerly technological notification number is that the Chinese utility model patent " optical coded lock " of CN201144561Y has disclosed, and then convert optical signal to the mode of unblanking that the signal of telecommunication is opened electric control lock again.The electric control lock that this technical scheme is similar to the password key mode mode of unblanking can not stay the use vestige but compare the traditional key-press mode, and again with the expansion that also can realize the password setting figure place after its supporting light cipher key cooperates.But the deficiency that this scheme exists is the raw mode that does not break away from password key; Only just realized the expansion of password figure place; The person does not carry out Based Intelligent Control through computer to its light cipher key if illegally unblank; Use computer software that the very limited optical coded lock of its figure place is carried out soft Brute Force, then this password setting mode just is difficult to stand tested again.
Summary of the invention
The technical problem that the present invention will solve just provides a kind of photoelectric combination lock system; Through the difficulty that cracks that crypto chip improves password is set respectively in lockset and key; And the mode through opto-electronic conversion makes code signal transmit through light, to overcome wireless signal easily by the drawback of illegal intercepting and capturing.

Accompanying drawing 2 width of cloth of the present invention.
Accompanying drawing 1a is the circuit block diagram of photoelectric combination lock described in the present invention.
Accompanying drawing 1b is the circuit block diagram of photoelectric password key described in the present invention.
Accompanying drawing 2 is the structural representation of photoelectric password key described in the present invention.
The specific embodiment
Shown in accompanying drawing 1a, 1b, a kind of photoelectric combination lock system, said system comprises:
Electric control lock, a kind of lockset by relay control;
Light sign indicating number generating apparatus is made up of light emitting diode, ID sign indicating number generation chip and battery, is used to generate the light coded signal that contains an ID sign indicating number;
Light sign indicating number receiving system is made up of photodiode, is used for the light coded signal that contains an ID sign indicating number is received and convert to the code signal;
Calibration equipment is made up of chip and the checking circuit of storing the 2nd ID sign indicating number, and be connected the code signal and the 2nd ID sign indicating number that are used for said apparatus output with above-mentioned light sign indicating number receiving system and compare verification, and the output verification result;
Control device is connected with electric control lock with calibration equipment, when verification succeeds, sends a unlocking signal to electric control lock, when verification is failed, does not export signal;
Above-mentioned light sign indicating number receiving system, calibration equipment, control device and electric control lock connect as one the formation photoelectric combination lock, and light sign indicating number generating apparatus is portable mancarried device, are the photoelectric password keys that is used with this photoelectric combination lock.
Wherein the storage chip of the generation chip of an ID sign indicating number and the 2nd ID sign indicating number is EPROM or PROM, and is preferable with EPROM.
A said ID sign indicating number and the 2nd ID sign indicating number be all by Morse code rule establishment, helps locking the preparation as required with key by the coding rule establishment password of unified standard.The user only need know contained numeral of its password or letter, then works out by unified binary coding rule when enrolling chip, as presses the coding rule of Morse code.
