Abstract
The utility model relates to a digital theftproof controller of a fuel oil vehicle. The digital theftproof controller comprises a fuel oil pipeline and a brake oil pipeline, and further has a keyboard entry circuit, a microcomputer, and a control relay connected with an output controlling end of the microcomputer, wherein, an input end of the microcomputer is connected with the keyboard entry circuit; a power loop is formed by a contact point of the control relay and an electromagnetic valve coil which is arranged on the fuel oil pipeline and the brake oil pipeline. A correct password is input by the keyboard entry circuit, the control relay works to lead an electromagnetic valve which is arranged on the fuel oil pipeline and the brake oil pipeline, and then the fuel oil pipeline and the brake oil pipeline are put through; contrarily, if the inputting password is not correct, the fuel oil pipeline and the brake oil pipeline cannot be put through. Namely, the connection between the fuel oil pipeline and the brake oil pipeline is controlled by the digital input, and people that do not know the password cannot decipher. Therefore, the theftproof effect is greatly increased, and vehicles are efficiently protected from being stolen.
Description
Technical field:
The utility model relates to a kind of anti-joyride device, specifically a kind of fuel combustion vehicle digital anti-theft controller.
Background technology:
At present, the stolen incident of domestic fuel combustion vehicle happens occasionally, stolen generally all to adopt measures such as control circuit and the antitheft equipment of sounding to carry out antitheft in order to prevent vehicle, and the car stealer only needs one master key and simple adjustment circuit can be stolen car, thereby above-mentioned anti-theft measure anti-theft effect is relatively poor.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of fuel combustion vehicle digital anti-theft controller of good anti-theft effect, with the connection of number input control fuel line and brake solution pipeline.
The purpose of this utility model is achieved in that it comprises fuel line and brake solution pipeline, it is characterized in that: also comprise micro computer that keyboard input circuit and input end link to each other with this circuit and the control relay that links to each other with the micro computer output control terminal, the contact of control relay constitutes electric power loop with the electromagnetic valve coil that is located on fuel line and the brake solution pipeline.Micro computer is made of microcomputer chip IC2 (T8C156) and memory IC 3 (24CL01).During use, by keyboard input circuit input digit password, when this numerical ciphers be stored in the micro computer digital code information when identical, micro computer output control signal makes relay work, and control electromagnetic valve on fuel line and the brake solution pipeline thus, make fuel line and the work of brake solution pipeline.
The utility model is not known that the password people can't decode, thereby is improved anti-theft effect greatly owing to be with the connection of number input control fuel line and brake solution pipeline, prevents that effectively vehicle is stolen.
Below in conjunction with accompanying drawing the utility model is done with explanation.
Description of drawings:
Fig. 1 is the utility model functional block diagram;
Fig. 2 is the utility model schematic circuit diagram.
The specific embodiment:
By accompanying drawing as can be known, the utility model by keyboard input circuit, micro computer, control relay and be located at fuel line and the brake solution pipeline on electromagnetic valve F
1, F
2Constitute.Keyboard input circuit JB adopts the YG-HH-242C model, and it is by 0-12 figure place sign indicating number, and this circuit output signal end links to each other with the micro computer signal input part; Micro computer is made of microcomputer chip IC2 (T8C156) and memory IC 3 (24CL01), the 6-9 pin of microcomputer chip IC2 is the signal input part that micro computer connects keyboard input circuit JB, its 10-12 pin links to each other with the 5-8 pin of memory IC 3, by microcomputer chip IC2 memory IC 3 is carried out read-write operation; Normal opened contact J with output control terminal (13 pin of IC2) the control relay J that links to each other of micro computer
1With the electromagnetic valve coil F that is located on fuel line and the brake solution pipeline
1, F
2Constitute electric power loop, when the input password is correct, the output control terminal of micro computer (13 pin of IC2) output control signal, aerotron T1 conducting, relay J adhesive work, its normal opened contact J
1Adhesive makes electromagnetic valve F
1, F
2Work, thus fuel line and brake solution pipeline are connected.If input password mistake, then relay J is not worked, and fuel line and brake solution pipeline can't be connected, and the car stealer can't be stolen car.IC1 is three end integrated stable voltage circuits 7805 among the figure, and it and capacitor C 1-C4, diode D1 constitute dc supply.
