Abstract
A password lock belongs to the technical fields of locks, keys, parts of doors and windows and safe boxes. The invention especially relates to an electronic password-checking lock and improvement of the password lock of a circuit thereof. The password lock provided in the invention is high in secrecy performance and is flexible in use. The password lock includes a main controller, an input module, a comparison module, a debugging module, a power supply module, a voice module, a loudspeaker, an unlocking controller, an execution mechanism and a displayer. The input module, the comparison module and the debugging module are connected to an input terminal of the main controller. The main controller is also connected to the power supply, the voice module, the loudspeaker, the unlocking controller, and the execution mechanism.
Description
Technical field
The invention belongs to lock; Key; Door and window part; Proof box technical field, especially relates to a kind of electric permutation lock; And the coded lock of circuit improves.
Background technology
Coded lock is the one of lock, and during unlatching is a series of numeral or symbol.The password of coded lock is all arrange and the combination of really usually.Partial password lock only uses a rotating disk, and the several video disc in lock or cam are rotated; Also some coded lock is the several thumb wheel circle being carved with numeral of rotation one group, directly drives the machinery that lock is inner.Along with the raising of people's living standard, especially outstanding how realizing that this problem of home security also becomes, traditional mechanical lock due to its construct simple, of common occurrence by the event of prizing.
General electronic lock security performance is not high, uses dirigibility bad, hinders promoting the use of of coded lock.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of security performance high and uses a kind of coded lock flexibly.
For achieving the above object, the present invention adopts following technical scheme, the present invention includes master controller, load module, comparison module, debugging module, power supply, voice module, loudspeaker, unlocking controller, topworks, display, it is characterized in that: load module, comparison module, debugging module are connected with the input port of master controller; Master controller is also connected with power supply, voice module, loudspeaker, unlocking controller, topworks.
As a kind of preferred version, master controller of the present invention is AT89S52 single-chip microcomputer.
Beneficial effect of the present invention.
The present invention, load module, comparison module, debugging module are connected with the input port of master controller; Master controller is also connected with power supply, voice module, loudspeaker, unlocking controller, topworks.By Single Chip Microcomputer (SCM) system, matrix keyboard, LED shows and warning system forms.System can complete unblank, time-out is reported to the police, time-out locking, keeper's deciphering, the basic coded lock of amendment user cipher function.Except above-mentioned basic function of cipher lock, also there is functions such as adjusting electricity storage, acousto-optic hint, distant control function can also be added according to actual situation, with low cost, practical function.
Accompanying drawing explanation
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with the drawings and the specific embodiments, the present invention is further elaborated.Should be appreciated that embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 is schematic block circuit diagram of the present invention.
Embodiment
As shown in the figure, the present invention includes master controller, load module, comparison module, debugging module, power supply, voice module, loudspeaker, unlocking controller, topworks, display, it is characterized in that: load module, comparison module, debugging module are connected with the input port of master controller; Master controller is also connected with power supply, voice module, loudspeaker, unlocking controller, topworks.
Master controller of the present invention is AT89S52 single-chip microcomputer.
When the password of user's input is correct and be that single-chip microcomputer just exports enabling signal, delivers to opening drive circuit, then drives electromagnetic lock, reaches the object of enabling in official hour input.
Drives and two-stage composition of unblanking.Form driving circuit by D5, R1, T10, wherein T10 can select common
Low-power transistor can meet the demands as 9014,9018.D5 is as the prompting unblanked; Be made up of D6, C24, T11.Wherein D6, C24 are to eliminate the issuable reverse high voltage of electromagnetic lock and issuable electromagnetic interference (EMI).T11 can select the triode of middle power as 8050, and selecting of electromagnetic lock will depend on the circumstances, but the suction-combining force wants enough and by certain surplus.
Because designing requirement uses matrix keyboard, so the design just adopts determinant keyboard, the number of I/O line shared when simultaneously can reduce keyboard and interface microcontroller, when button is many, this quadrat method of employing usually.
Because designing requirement uses matrix keyboard, so the design just adopts determinant keyboard, the number of I/O line shared when simultaneously can reduce keyboard and interface microcontroller, when button is many, this quadrat method of employing usually.10 numerical keys are used for inputting password, other 6 function keys respectively: CLR, EN, F1, F2, F3, F4.Wherein the function of CLR key is that the data inputted before removing, re-enter when input code error time.The function of EN key is the password confirming input.F1 is management mode switch key, and when careless three the input passwords of user all do not have correctly, keyboard is locked, and this time just can start management mode, and the password of use management person opens the door.F2 is used to the state entering Modify password.F3 is used for closing display, and one can save electricity, also can prevent lawless person's snooping password in addition.F4 is used for electric bell.3 pilot lamp L1, L2, L3 are used to the state of instruction operation: L1 locking and input indicating status lamp, show redness in normal situation, when keyboard action time, L1 lamp starts to flash, and when the keypad is in a locked state, pilot lamp also shows redness.L2 opening indicating lamp, have input password when user is correct in official hour, this lamp changes green into, represents and opens the door, otherwise do not show.L3 is admin state pilot lamp, and after pressing F1, pilot lamp is lighted automatically.Panel also has a hummer, and whether the button that one of them function is used to instruction operation is successfully being pressed; Another one function is that the number of times inputting code error as user has exceeded 3 times, blows a whistle to show warning.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
