Abstract

The utility model discloses a light control smart lock, matrix keyboard module comprises photoelectric sensor, be used for the user to input the password, the matrix keyboard module that photoelectric sensor constitutes links to each other with STC89C52 singlechip host system, compare to the password of user's input through STC89C52 singlechip host system, STC89C52 singlechip host system and control relay are unblanked the module and are linked to each other, it makes the actuation of electronic lock solenoid to unblank the closure of module through the control relay, STC89C52 singlechip host system still links to each other with 2.0 principal and subordinate's all -in -ones of bluetooth and liquid crystal display module, the password the mandate sign indicating number change STC89C52 singlechip host system that come from cell -phone communication module inside stored is received through 2.0 principal and subordinate's all -in -ones of bluetooth, add simultaneously the liquid crystal display module indicate input/output to the mistake. The utility model discloses replace digital button keyboard with photoelectric sensor, it is lower to have a cost, and the security performance is high, easy operation's advantage.

Description

A kind of light control smart lock

Technical field

The utility model relates to smart lock technical field, is specially a kind of light control smart lock.

Background technology

In daily live and work, the preservation of the safety precaution work of family residence and department, the archive files of unit, financial statement and valuables etc. solves mainly with the way of " locking ".Use traditional mechanical lock, usually need to carry a large amount of keys, also easily take key during use by mistake and destroy lockset, once the key loss of traditional mechanical lock, the security of lockset will become extremely low, and need consumption fund to change lockset, cause economic loss.Along with the development of science and technology, people require more and more higher for this various daily neces saries being often used as safety protective tool of lock in daily life.Increasing its security to meet different crowd for the requirement of lock, to access to your password or applying biological recognition technology arises at the historic moment as the smart lock of key.This kind of smart lock has that security performance is high, cost is low, low in energy consumption, easy to operate, remember the advantage that password can unlock, day by day become the first-selection of different crowd, present market is modal is still more traditional push-button puzzle lock, easily leaves fingerprint etc. and to divulge a secret vestige.

Utility model content

The purpose of this utility model is to provide a kind of light control smart lock, to solve the problems of the technologies described above.

The present invention is by the following technical solutions for achieving the above object:

A kind of light control smart lock, comprise STC89C52 single-chip microcomputer main control module, matrix keyboard module, bluetooth 2.0 principal and subordinate all-in-one module, mobile communication module, LCD MODULE, relay is unblanked module, described matrix keyboard module is made up of photoelectric sensor, password is inputted for user, the matrix keyboard module of photoelectric sensor composition is connected with STC89C52 single-chip microcomputer main control module, by STC89C52 single-chip microcomputer main control module, the password that user inputs is compared, STC89C52 single-chip microcomputer main control module and pilot relay module of unblanking is connected, the adhesive of electronic lock solenoid is made by pilot relay the closed of module of unblanking, STC89C52 single-chip microcomputer main control module is also connected with bluetooth 2.0 principal and subordinate's all-in-one and LCD MODULE, the password of the authorization code change STC89C52 single-chip microcomputer main control module internal reservoir from mobile communication module is received by bluetooth 2.0 principal and subordinate all-in-one, add simultaneously liquid crystal display module to point out input and output to mistake.

The beneficial effects of the utility model are: the utility model replaces keypad with photoelectric sensor, and its control system, based on singlechip technology, realizes unblanking, Modify password, the functions such as code error warning, have cost lower, security performance is high, advantage simple to operate.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.

As shown in Figure 1, a kind of light control smart lock, comprise STC89C52 single-chip microcomputer main control module, matrix keyboard module, bluetooth 2.0 principal and subordinate all-in-one module, mobile communication module, LCD MODULE, relay is unblanked module, described matrix keyboard module is made up of photoelectric sensor, password is inputted for user, the matrix keyboard module of photoelectric sensor composition is connected with STC89C52 single-chip microcomputer main control module, by STC89C52 single-chip microcomputer main control module, the password that user inputs is compared, if the password of user's input is identical with the password stored in system, program of unblanking then in activation system, STC89C52 single-chip microcomputer main control module and pilot relay module of unblanking is connected, the adhesive of electronic lock solenoid is made by pilot relay the closed of module of unblanking, realize the object of unblanking, STC89C52 single-chip microcomputer main control module is also connected with bluetooth 2.0 principal and subordinate's all-in-one and LCD MODULE, received the password can changing STC89C52 single-chip microcomputer main control module internal reservoir from the authorization code of mobile communication module at any time by bluetooth 2.0 principal and subordinate all-in-one, add simultaneously liquid crystal display module to point out input and output to mistake.

When user attempts to open lock, first must input correct unblock gesture password by the matrix keyboard be made up of photoelectric sensor lock could be opened, corresponding prompting is had when Password Input mistake, in order to improve security, when Password Input mistake reaches three times, system will automatically lock a period of time, not allow during this period again to input password, and password can be set by user oneself and modify.

As shown in Figure 2, principle of work of the present utility model, photoelectric intelligent coded lock needs when there being people to want to unblank first to press a power switch button, thus activation whole system, this time inputs default gesture password by finger or human body any part at the induction region of input gesture password again.Now the hand signal that people inputs is converted into light signal by photoelectric sensor, light signal changes electric signal again into and imports STC89C52 single-chip microcomputer main control module into, the signal of STC89C52 single-chip microcomputer main control module to input carries out process comparison, if identical with preset password, namely send actuating signal a to pilot relay to unblank module, pilot relay is unblanked module action after receiving signal, electromagnetic lock just can be allowed to open, reach the object of unblanking.Due to whole system employing is that photoelectric sensor is as flip flop equipment, photoelectric sensor is to the special sensitize of light signal, faint light change all can cause system mistake to run, input error password, when repeatedly input error password time, system will lock the regular hour, so just needed pressing shift knob activation system before input password, this shift knob is an activator switch of whole system.

Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
