Description
Technical field
The invention belongs to technical field of communication safety and comprising, be specifically related to a kind of SCM Based electronic password lock.
Background technology
In the middle of daily life, a kind of utensil that lockset right and wrong are usually shown in.Regardless of which industry, all it be unable to do without lock.Since ancient times, lock just has miscellaneous, each epoch, and the form of lock all can be different.Why lock can be the most common？The effect of lock, is exactly nothing but two words: antitheft.Through the ages, pilferage is the most all present in the middle of this society.Because there being the reality of gap between the rich and the poor, the existence of selfish psychology, pilferage would not be withered away.People, in order to deal with pilferage, then occur in that lock.
Lock is almost born with private ownership simultaneously.In Chinese Yangshao culture a long time ago, occur as soon as wooden lockset.At the Eastern Han Dynasty, the ferrum lock of China has had a high level.Modern age, along with the development of microelectric technique, occur in that many novel locksets, such as: locked by the acoustic control of sound control, with the electronic cards mortice lock of electronic card identification and can be with the remote-controlled lock of Remote, by the Fingerprint Lock of fingerprint recognition, with retina lock of retina identification etc..These locksets are much higher relative to traditional mechanical lock security performance.Modern lock can also be controlled by program in the middle of specific environment.Typical Representative therein is exactly electronic password lock.
Someone designs lock, just someone will study and how to go to unblank.The security performance of then many locks declines as well as the raising of unlocking technique.So the development of lockset now is nothing but to develop toward the direction that security performance is high.The lock that security performance is the highest, will be the most welcome.
Along with the invention of various new techniques, also have various locking out now, in we watch various film, occurred as soon as the lock that a lot of imaginative power is the highest.The lockset wherein made of fingerprint, sound, pupil, electronic cards, password etc. should be able to be main flow.
And present, along with the development of science and technology, the requirement of electronic lock is the highest, accordingly, it is desirable to provide a kind of security performance is high, it is low to put into, the convenient lockset used.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of SCM Based electronic password lock social for antitheft demand now to adapt to.
A kind of SCM Based electronic coding lock system, described electronic coding lock system includes matrix keyboard, alarm module, the display module that main control chip 52 single-chip microcomputer and each port with described 52 single-chip microcomputers be connected, unblank part, reset portion.
Preferably, described electronic coding lock system passes through input through keyboard password, and by confirming that button, cancellation button and password amendment button carry out the function selecting of completion system.
Preferably, described display module is 1602 displays, and D is used for encrypted message when showing input through keyboard and the operation prompt information before and after prompting user's input.
Preferably, described alarm buzzer alarm sound when Password Input mistake.
Preferably, described electronic coding lock system is by the input of single-chip microcomputer scanning button, and by the password of input with correct unlocking cipher compared with: if correct, just being sent out a signal to unblanking part by single-chip microcomputer, light emitting diode is bright, and expression is unblanked；If mistake, single-chip microcomputer send out one instruction to alarm module, buzzer sends alarm sound.
Technical scheme has the advantages that
The present invention provides a kind of SCM Based electronic coding lock system, use 52 single-chip microcomputers as control chip, matrix keyboard is as input equipment, buzzer is done alarm, liquid crystal 1602 is as display device, achieve lockset safety performance height, put into demand that is low and that be convenient to use, social for antitheft demand now to adapt to.
Accompanying drawing explanation
Below by drawings and Examples, technical scheme is described in further detail.
Fig. 1 is a kind of SCM Based electronic coding lock system overall framework figure of the present invention.
Detailed description of the invention
In order to have a clear understanding of technical scheme, its detailed structure be will be set forth in the description that follows.Obviously, the concrete also deficiency of implementing of the embodiment of the present invention is limited to the specific details that those skilled in the art is familiar with.The preferred embodiments of the present invention are described in detail as follows, in addition to these embodiments described in detail, it is also possible to have other embodiments.
With embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.
With reference to Fig. 1, as it can be seen, disclose a kind of SCM Based electronic coding lock system, main control chip is 52 single-chip microcomputers, wherein matrix keyboard, alarm module, display module, part of unblanking, reset portion are all connected on each port of single-chip microcomputer, by Single-chip Controlling modules.As shown in Figure 1.
According to system block diagram, the main devices necessarily used in system has: single-chip microcomputer, matrix keyboard, buzzer, 1602 liquid crystal displays.
Fundamental relation between each device is: by input through keyboard password, and by confirming that button, cancellation button and password amendment button carry out the function selecting of completion system.LCD is used for encrypted message when showing input through keyboard and the operation prompt information before and after prompting user's input.Alarm buzzer alarm sound when Password Input mistake.
Finally, single-chip microcomputer is the core controller of whole system, is the heart of system.By the input of single-chip microcomputer scanning button, and by the password of input compared with correct unlocking cipher, if correctly, just being sent out a signal to unblanking part by single-chip microcomputer, light emitting diode is bright, and expression is unblanked, if mistake, single-chip microcomputer send out one instruction to alarm module, buzzer sends alarm sound.
