Description

Relay decoding anti-theft device for vehicle

The utility model relates to a kind of anti-theft device for vehicle, particularly a kind of relay decoding anti-theft device for vehicle that utilizes the vehicle turn signal signal control

At present, vehicle anti-theft is reported to the police of a great variety, and distance type electronic anti-theft device, password electronic anti-theft device etc. are arranged; improved the theftproof performance of vehicle, but also there are a lot of shortcomings in it, complex structure in using; difficulty is installed, and price is expensive, particularly distance-type product; its radio remote control switch, malfunctioning through regular meeting operation, easily lose; water funk pouring, warning circuit are subjected to acoustic noises and cause flase alarm, produce noise; influence the living environment quietness, bring unnecessary trouble to people.

The purpose of this utility model is for the shortcoming that overcomes above-mentioned prior art provides a kind of relay decoding anti-theft device for vehicle, utilizes the vehicle turn signal signal decoding, control ignition and motor power, the theftproof performance of raising vehicle.

The purpose of this utility model can realize by following technical measures: this Car Burglar Alarm has the centring control integrated package, this integrated package has coding, comparison, time-delay, storage information function, its power input connects vehicle car key switch, signal input part connects the left and right steering indicating light of vehicle respectively, its warning signal mouth connects loudspeaker through amplifier integrated block, control signal output ends connects amplifier integrated block, amplifier integrated block connects the relay of two parallel connections, and one of them relay connects the vehicle ignition circuit, another relay connects motor circuit.After establish the password locking vehicle, the car key electric switch is connected, connect igniting and motor circuit by steering indicating light signal input decoding, vehicle normally uses.If the code signal of input error, igniting and motor circuit are disconnected, and vehicle can't use, and sends alarm sound simultaneously.

Concrete structure lattice embodiment of the present utility model is provided by the following drawings:

Fig. 1 is the circuit diagram of relay decoding anti-theft device for vehicle.

The utility model is described in further detail below with reference to accompanying drawing: with reference to Fig. 1, and the centring control ic chip ₁Output pin 1,2 connect vehicle car key switch K ₁, the power supply of control circuit, IC ₁Input pin 3,4 connect respectively that vehicle turns left, dextrad lamp L, R, K ₂Be the turn signal swich of vehicle, with the impulse singla of vehicle turn signal relay Der Blink und Abblendschalter as decoded signal, IC ₁The password that middle input is stored is preferably 4 figure places, by K switch ₁The control input, IC ₁Exchange raise-position, decoding counting, error code alarm, function such as delay locked are arranged, the impulse singla of steering indicating light relay Der Blink und Abblendschalter is changed into numeral accumulation number and password compares, export control signal again, as setting code is 1234, decoding is just opened the left steering lamp and is dodged 1 time, the right steering lamp dodges 2 times, and the left steering lamp dodges 3 times, and the right steering lamp dodges 4 times.The centring control ic chip ₁Output pin 1,2 connect the indication ic chips ₂, IC ₂The indicator lamp that connects two parallel connections shows that decoding is wrong right; IC ₁Output pin 4,5 connects ic chip ₃, IC ₃Connect loudspeaker r, warning signal is through IC ₃Amplification after send loudspeaker r; IC ₁Output pin 6,7 connects amplification integrated block IC ₄, 1C ₄The relay J that connects two parallel connections ₁, J ₂, J ₁The firing circuit that connects vehicle, the work of control ignition coil, J ₂The motor circuit that connects vehicle, the work of control motor.After vehicle is opened electric switch, input proper password, J ₁, J ₂Connect igniting, motor circuit, vehicle normally uses, the input error password, and vehicle can not use, simultaneously alarm; After closing electric switch, the protector time-delay automatically locks.

The utility model is made decoded signal with the Vehicular turn modulating signal, simplified its structure, cost-cutting, simple, easy with the tipping of vehicle circuit, have password locking, error code warning, delay locked function, operation control is sensitive, good stability, strengthen the theftproof performance of vehicle, helped the stable of society.

Claims (1)

1. a relay decoding anti-theft device for vehicle is characterized in that the centring control ic chip ₁The power supply input pin meet car key switch K ₁, signal input part 3,4 connects the left and right steering indicating light L of vehicle, R respectively, and mouth 4,5 is through amplification integrated block IC ₃Connect loudspeaker, mouth 7,8 is through amplification integrated block IC ₄The relay J that connects two parallel connections ₁, J ₂, J ₁, J ₂Connect vehicle ignition, motor circuit respectively.
