Abstract
The utility model discloses a digital password lock, and aims at solving the problem that an existing mechanical lock is easy to copy and unsafe. The digital password lock comprises a control system, an input module, an electromagnetic lock module and a power supply, wherein the power supply supplies electricity to each module; the control system is connected with the input module and the electromagnetic lock module; the electromagnetic lock module comprises an on-off control device insulated gate bipolar translator (IGBT) unit; the control system is connected with an IGBT unit trigger gate pole. The IGBT has higher stress level, higher breakover current, and more frequent breaking capacity, so that the electromagnetic lock circuit is more flexible to control. In addition, the Arduino control system-based digital password lock design is low in cost and high in stability.
Description
Technical field
The invention belongs to digital cipher lock, be specifically related to the digital cipher lock based on Arduion.
Background technology
Current China most residents is being used mechanical lock, and mechanical lock utilizes mechanical principle, and key is easily replicated, some manufacture crafts poor lockset relative to technology particularly, and key is more easily replicated.Security is not high.Given this, need to design the higher novel radio electronic password lock of a kind of security.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of digital cipher lock, take Arduino control system as core, take power electronic devices IGBT as electromagnetic lock switch, can realize numerical ciphers lock cipher and show, voice message, Modify password, the functions such as automatic alarm.Arduino control system is simple in structure, reliable and stable, more flexibly light and handy with respect to single-chip computer control system, controls the break-make of electromagnetic lock circuit with power electronic devices IGBT simultaneously, more quick, reliable.
Technical scheme of the present invention is: a kind of digital cipher lock, comprise control system, load module, electromagnetic lock module and power supply, and power supply is each module for power supply, control system connects load module and electromagnetic lock module; Described electromagnetic lock module comprises cut-offs control device IGBT unit, and control system connects IGBT unit triggers gate pole.
Further improvement as this programme: described load module is 4*4 matrix keyboard.
Further improvement as this programme: described control system is the control system based on Arduino.
Further improvement as this programme: described digital cipher lock also comprises I/O peripheral hardware expansion interface, control system connects I/O peripheral hardware expansion interface.
Further improvement as this programme: described digital cipher lock also comprises LED display module, LED display module is by I/O peripheral hardware expansion interface connection control system.
Further improvement as this programme: described digital cipher lock also comprises standby savings power supply is each module for power supply during grid cut-off.
Further improvement as this programme: described digital cipher lock also comprises warning device, warning device is by I/O peripheral hardware expansion interface connection control system.
The present invention has following good effect: (1) is higher voltage withstand class because IGBT has, larger On current, and make-break capacity, controls electromagnetic lock circuit more flexible more frequently.(2) design of the digital cipher lock based on Arduino control system, with low cost.

Fig. 1 is digital cipher lock system chart;
Fig. 2 is digital cipher lock workflow diagram.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
As shown in Figure 1, the digital cipher lock designed system block diagram based on Arduino control system, comprises power supply, standby savings power supply, keyboard, light-emitting diode display, warning circuit, electromagnetic lock module part.
Digital cipher lock be take Arduino control system as core.By the expansion of corresponding I/O Interface realization Arduino port, by the port of expanding, connect respectively corresponding peripheral hardware.Comprise keyboard, light-emitting diode display, hummer, voice warning circuit, the trigger terminal of power electronic devices IGBT is as corresponding input-output device.Control system receives and gathers the signal of corresponding input equipment and processes, and result is by corresponding output device output display.
During real work, using keyboard peripheral hardware as input variable, after processing by signal, input Arduino controller carries out signal processing, by password, compare, get corresponding results, by output device, carry out output display, realize to corresponding unlock circuit the control of the circuit such as warning simultaneously.
Wherein common single-phase bridge rectification circuit for power acquisition, becomes by domestic power supply the power supply that this circuit can be used, and adds standby savings power supply simultaneously, prevents that the situation of grid cut-off from occurring.LED display module adopts integrated LED lattice module, can show " please input password ", Chinese character informations such as " password mistakes ".Keysheet module adopts matrix keyboard.Keyboard shows 0-9 numeral, also has " determining ", " removing ", " modification ", " STAR ", " END ", inputs Arduino controller after by scrambler, corresponding button being encoded and processes, and can realize the operations such as coded lock Modify password.Electromagnetic lock module adopts power electronic devices IGBT to cut-off control device as electromagnetic relay.After Password Input is correct, Arduino controller connects IGBT and triggers gate pole, realizes IGBT conducting, and electromagnetic relay obtains electric, electromagnetic relay adhesive dead bolt.Now can open the door by swing handle.While unclamping handle, by linkage, make IGBT obtain reverse voltage, thereby make IGBT cut-off, relay electric-loss, dead bolt is replied.
As shown in Figure 2, the process flow diagram of the design of the digital cipher lock based on Arduino control system.Press " STAR " key, program starts initialization, reads password is set.Now start voice message, input password.Input starts time set during password, if complete operation not in 30 seconds, program is closed automatically.After input password, carry out the judgement of password correctness, if correct, can unblank or the operation of Modify password, if incorrect, can obtain the voice message of extra twice input password, if all incorrect, the terminal that connects hummer sends high level output, and hummer can send alerting signal, and can continue for some time.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
