The utility model relates to a kind of license plate, relates in particular to a kind of anti-hijacking remote control alarm licence plate.

At present, license plate for vehicle is easily lost on the market, and automobile often is held as a hostage, and chaufeur also often comes to harm.A kind of motor vehicle antitheft license plate of announcing on the Patent Gazette for Utility Models, it is by in the frame of the bottom of bare bones movable part being set, be respectively arranged with the upper and lower half branch of licence plate numerical code on movable part and the bare bones, in a single day movable part is taken away, the printed words that then expose " forbidding travelling " on the plate behind the bare bones ", thus reach theft-proof purpose.But only relate to the antitheft of licence plate, do not possess the theft-proof function of self-propelled vehicle itself, thus function singleness, and destroyed easily, make it can't reach anti-theft feature.

The utility model is made up of sensing circuit, light-operated circuit and licence plate display circuit, sensing circuit involving vibrations sensing circuit and ultrasonic sensing circuit, aerotron and relay are formed, finish vibration, ultrasonic signal sampling, amplify with control relay, then control board is according to the abnormal indication of display circuit, and light-operated circuit is got optical signal by photoconductive cell and shown night with the licence plate of control board according to display circuit.

The utility model also has additional radio remote control circuit, with the break-make of remote-control car high-tension coil for strengthening its anti-theft feature.

The utility model removes tool light and reports to the police, and also is provided with sound alarm circuit.

Safety traffic and anti-hijacking that the utility model reasonable in design, cost be low, can be widely used in power actuated vehicle, it has following function:

1, not other or by remote-control closedown as the car owner at vehicle, this moment the car engine ignition coil blackout, vehicle motor can not retrofire, can prevent effectively that vehicle is stolen, the driver is prominent simultaneously when running into dangerous situation, but the emergency control automobile flameout;

2, Car No. is double-colored demonstration, and one (as green) is golden for peace, another (as redness) alarm look, show car plate by light-operated circuit control night, in case take place to kidnap or raise a cry or revolt the vibration that causes, car plate is shown as the alarm look, sends acoustic alarm simultaneously;

3, can effectively in time hit and tackle misfortune car criminal,, reduce and pre-anti-robbing automobile crime, positive role is arranged maintaining public order.

Below in conjunction with accompanying drawing the utility model is elaborated.

The utility model is made up of radio remote control circuit, vibrating sensing circuit, ultrasonic sensing circuit, light-operated circuit, licence plate display circuit and sound alarm circuit.Radio remote control circuit comprises by wireless remote control transmitter module IC ₁(the projector that RMC-(A), power supply E and ammonium button master cock K constitute and by wireless remote control receiver module IC ₂(RMC-(B), double D trigger IC ₃With amplifying triode BG ₁, relay J ₁The reception controller that constitutes is formed.By wireless remote control receiver module IC ₂Receive IC ₁The signal that sends is delivered to double D trigger 3 pin by pin 2, and double D trigger the right is connected into monostable circuit, and the left side is connected into bistable circuit, by IC ₃ Pin 3 signal is delivered to amplifying triode BG ₁Base stage, relay J ₁Cross-over connection is in aerotron BG ₁Collecting electrode and IC ₂4 on pin, its open contact is connected to automobile ignition coil.When pressing transmitter power master cock K, IC ₁Module space is towards periphery sent high-frequency modulation signal, in the EFFECTIVE RANGE scope, by IC ₂Module receives, and through internal circuit demodulation, amplification, detection, after time-delay and the level conversion, makes IC ₂Pin 2 is transferred to high level and is directly triggered the monostable circuit upset once by original low level, and a defeated positive arteries and veins spare, and its positive rise reliably triggers bistable circuit, makes its bistable circuit output state change once aerotron BG ₁By original by or conducting transfer conducting to or end, thereby to relay J ₁Power supply or outage realize the radio remote control switch function.Sensing circuit of the present utility model is by vibrating sensing circuit, ultrasonic sensing circuit and aerotron BG ₂, relay J ₂Form.The vibrating sensing circuit is by vibration sensor, piezoceramic HD ₁, field effect transistor V ₁, adjustable potentiometer W ₁, IC ₄(555), R ₁, C ₁And other Resistor-Capacitor Unit is formed R ₁, C ₁And IC ₄Constitute the monostable time delay circuit, vibration sensor HTD ₁Signal is through field effect transistor V ₁Send into IC4 after the amplification ₂Pin, IC ₄Pin 3 exports aerotron BG to ₂Base stage.The ultrasonic sensing circuit is by sonac HTD ₂And four transport and placing device IC ₅～IC ₈The multistage amplifier circuit that other Resistor-Capacitor Unit constitutes is formed.Vibration sensor no signal (promptly do not have certain external cause vibration) at ordinary times, circuit is in stand-by state, field effect transistor V ₁End C ₁Through R ₁Charge to high level, so IC ₁Pin 6 is a high level, and 3 on mouth pin is a low level, relay J ₂If not adhesive of coil of wire no current vibration sensor HTD ₁Last steel ball is vibrated by external cause, and signal is then arranged, through field effect transistor V ₁Amplify and be added on IC ₄Pin 2 makes IC ₄Upset, pin 3 output high level, relay J ₂Get electric adhesive.Can realize that the someone steals car, fight causes vibration and reports to the police.When vehicle was held as a hostage, fight and loud call, sonac HTD may take place in chaufeur and criminal ₂Receive a certain amount of impact and high-decibel sound wave, send signal, deliver to aerotron BG through multistage amplification ₂Base stage makes relay J ₂Electric adhesive, concurrently speak, light reports to the police, can be effectively in time and interception rob the car criminal.Light-operated circuit of the present utility model is by photoconductive cell R ₂, aerotron BG ₃, relay J ₄And flash of light IC ₉(UAA ₁₀₄₁B) field effect transistor V ₂, other Resistor-Capacitor Unit forms.The licence plate display circuit is made up of many groups of double-colored high brightness diodes.When the curtain of night comes, photoconductive cell changes, and when darkness reaches certain program, makes aerotron BG ₃Conducting, relay J ₄Get electric adhesive, through field effect transistor V ₂Deliver to two-color diode, show the safety color green,, as vibration sensor, sonac output is arranged, relay J in case dangerous situation is arranged ₂Must be electric, through V ₂, show the waming color redness.Sound alarm circuit of the present utility model is by oscillator IC ₁₀(KD- ₉₅₀₁), amplifier IC ₁₁(TWH ₈₇₅₂) and loud speaker T composition.
