The utility model is achieved through the following technical solutions: a kind of electronic cipher control system based on digital circuit, overcome the defective of existing machinery formula coded lock poor safety performance, the design scheme that has proposed to access to your password and replaced key to unblank, its structure comprises the coded lock control unit that is provided with unlock circuit, be provided with password input switch in described coded lock control unit, described coded lock control unit is the control module by password input switch input password and then the work of control unlock circuit, be provided with power supply in described coded lock control unit, have safe, cost is low, advantage such as easy to operate.
For better realizing said structure, described coded lock control unit comprises cipher code storing electric circuit and the password identification circuit that links to each other successively, described cipher code storing electric circuit is connected on the password input switch, and described password identification circuit then is connected with unlock circuit.
For better realizing the utility model, described coded lock control unit also comprises the wrong input mechanism of being made up of latch and warning circuit, described warning circuit is connected on the password identification circuit, described latch is the self-locking device for receiving the warning circuit feedback signal and being connected with password input switch and password identification circuit respectively then, in actual application, when feedback signal reaches twice when above (that is: password mistake input number of times is more than twice), it is then invalid to carry out the password input by password input switch again, has more strengthened safety of the present utility model.
In the utility model, described warning circuit is the integrated circuit of being made up of IC5 integrated chip and buzzer, and described IC5 integrated chip is connected on the password identification circuit, and circuit structure is very simple.
The utility model also is provided with the indicator lamp L that unblanks on described unlock circuit, have the prompting unblanked, and is user-friendly to.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is simple in structure, overcome the defective of existing machinery formula coded lock poor safety performance, the design scheme that has proposed to access to your password and replaced key to unblank, can not only satisfy people to the instructions for use of lock, also increase safety, had advantages such as cost is low, low in energy consumption, easy to operate.
(2) in actual fabrication process of the present utility model, each functional module can adopt production of integrated circuits to form, and makes very simply, with low cost, can be applicable to use convenient as the anti theft design of commercial area, residential quarter.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the utility model of embodiment, but embodiment of the present utility model is not limited thereto.
Embodiment:
Along with the raising of people's living standard, especially outstanding that the keeping of home security and capsule information also becomes, traditional mechanical lock are because its structure simple and adopt material such as copper, aluminium, zinc etc. resists strong destruction, and the event that quilt is prized is of common occurrence.Therefore the utility model has been put forward a kind of electronic cipher control system based on digital circuit, defectives such as above-mentioned mechanical code lock poor safety performance have been overcome, the design scheme that has proposed to access to your password and replaced key to unblank, its structure as shown in Figure 1, comprise the coded lock control unit that is provided with unlock circuit, be provided with password input switch in coded lock control unit.In the utility model, coded lock control unit is the control module by password input switch input password and then the work of control unlock circuit, be provided with power supply in coded lock control unit, during use, adopt the password input can realize unblanking, easy to operate, but wide popularization and application in as: the anti theft design in places such as commercial area, residential quarter, security performance is strong.
As shown in Figure 1, coded lock control unit comprises cipher code storing electric circuit and the password identification circuit that links to each other successively, and cipher code storing electric circuit is connected on the password input switch, and password identification circuit then is connected with unlock circuit.In the utility model, password identification circuit can adopt CD4072, unlocking cipher can be arranged to the four figures password, import by the S1～S4 button of password input switch respectively, cipher code storing electric circuit can adopt storage chip (as: AT24C02), in its circuit structure, store correct unlocking cipher in the AT24C02, after the user is by input (that is: password input switch) input password, need to pass through successively the analysis of password holder and password identification circuit, if password is correct, then be sent in the unlock circuit by password identification circuit output right instructions, as shown in Figure 1, unlock circuit comprises NE555 integrated chip and relay K, the NE555 integrated chip receives the instruction that sends from password identification circuit, and take this as a foundation, the adhesive of control relay K and release, for better realizing said structure, the utility model also is parallel with light emitting diode at the two ends of relay K, that is: the indicator lamp L that unblanks is when password is imported when correct the relay K adhesive, door lock is opened, and the indicator lamp L that unblanks is bright.
