Description
Technical field
The utility model relates to a kind of coded lock, relates in particular to the coded lock control circuit that has remote control.
Background technology
Coded lock is used very extensive, common coded lock in daily life and is generally all comprised digital input key and some function keys, and button is more, is not very suitable in some application scenarios, such as lock for motorcycle.Now a lot of in addition coded locks all have distant control function, but lack the password setting function again, and are in use very dangerous.
Summary of the invention
In order to overcome the problem of above-mentioned proposition, the utility model provides a kind of coded lock control circuit, is used to provide the function of password setting function and remote control, and the convenience in both having guaranteed to use has also guaranteed safety simultaneously.
The utility model is to realize above-mentioned purpose by following technical proposals, a kind of coded lock control circuit, it is characterized in that, comprise radiating circuit, receiving circuit, CPU, display driver circuit, lock control circuit, reset circuit, described radiating circuit comprises a button or two buttons, emission drive circuit and transmitter; Described receiving circuit comprises receiver and a photoelectric switching circuit adaptive with transmitter, and output links to each other with CPU; Described display driver circuit receives the control signal of CPU, and links to each other with display module; Described reset circuit links to each other with CPU; Described lock control circuit receives the control signal of CPU, is used to control opening or closing of coded lock.In this scheme, realize the function of remote control by radiating circuit and receiving circuit, the function that or two buttons are realized the password input is set in radiating circuit, button adopts different encoding schemes to realize the input of different numerals.CPU is the major control part of whole proposal, can decode the action that comes control assembly according to the password of importing simultaneously to the signal of button input by software.
As preferably, also comprise the keyboard treatment circuit, described keyboard treatment circuit comprises a button or two buttons, this keyboard treatment circuit output links to each other with CPU.When not using the radiating circuit part, also can input password by this keyboard treatment circuit.Equally, this keyboard treatment circuit also adopts a button or two buttons, adopts the numeric coding scheme identical with the radiating circuit part.
As preferably, also comprise warning circuit, described warning circuit input and CPU control signal, output links to each other with voice guard.This warning circuit is used to drive voice guard.
As preferably, also comprise the key that opens the door, output links to each other with CPU, is used for directly unblanking.
As preferably, described CPU is the 89C51 single-chip microcomputer.CPU in this programme is 89C51, also can handle for other single-chip microcomputers carry out signal.This single-chip microcomputer is mainly used in keyboard-coding, and controls different parts actions according to the difference of input password.
As preferably, described transmitter is an infrared-emitting diode, and described receiver is an infrared receiving diode.In order to realize the function of remote control, the most general infrared diode that receiver that this programme adopts and transmitter can adopt is realized.
The beneficial effect of this programme is: by adopt a button or two buttons in radiating circuit and keyboard treatment circuit, and combine with CPU, realize realizing password input function with minimum button, it is very little to make radiating portion to accomplish, realize distant control function by receiving circuit and radiating circuit simultaneously, in use very convenient, also have safety preferably simultaneously.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment the utility model is further set forth.
Implementation column 1: as shown in Figure 1, a kind of coded lock control of the utility model circuit comprises radiating circuit, receiving circuit, CPU, display driver circuit, lock control circuit, reset circuit, and radiating circuit comprises two buttons, emission drive circuit and transmitter; Receiving circuit comprises receiver and a photoelectric switching circuit adaptive with transmitter, and output links to each other with CPU; Display driver circuit receives the control signal of CPU, and links to each other with display module; Reset circuit links to each other with CPU, is used for starting working after CPU powers on; The lock control circuit receives the control signal of CPU, is used for the unlatching of control lock.This control circuit also comprises warning circuit, and this warning circuit input links to each other with CPU, and output links to each other with a buzzer.
In order to realize realizing the input of different digital with minimum button, need encode to the input of button, this programme adopts following encoding scheme: 1. radiating circuit is provided with two buttons, one is digital input key, one is acknowledgement key, and the time of each button meets or exceeds 0.3S and is effective button once; According to numeral how much decide what of touch potential, press acknowledgement key then and decide.3. confirm the bond distance by 5S for re-entering.
The power supply of the radiating circuit of this operational version is powered by battery.And the power supply of CPU part can adopt battery also can adopt according to actual conditions to adopt other modes to power.After power supply begins power supply, reset circuit work, CPU starts working, and concrete workflow is as follows:
1. the user inputs password by the button of radiating circuit, and CPU decodes according to encoding scheme, and the password that sets with CPU compares then, if correct, with regard to the control lock control circuit lock is opened so.When numeral of each input was finished, CPU gave control signal of display driver circuit simultaneously, and display module shows the numeral of input.In the time of each button, buzzer sends a sound.
2. if digital input error so can be by re-entering by acknowledgement key 5S.
3. if import continuous 3 mistakes of password, CPU just stopped to decode 5 minutes so, and this time can make amendment according to actual conditions.After 5 minutes, just can re-enter password.The buzzer 30S that can yowl simultaneously.
Embodiment 2: according to embodiment 1, this programme increases a keyboard treatment circuit thereon, and this keyboard treatment circuit comprises two buttons, and output links to each other with CPU, the encoding scheme that numerical key adopts is identical with embodiment 1, also can directly input password by button like this.
Embodiment 3: according to embodiment 2, this programme increases the key that opens the door thereon, if the application scenario of this lock is door time in house, the user just can directly open lock by the key that opens the door in indoor use, avoids like this inputing password by remote controller.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
