Along with improving constantly of living standard, electric motor car, car extensively become people's walking-replacing tool.Thing followed thievery takes place repeatedly, and therefore, various vehicle anti-theft devices arise at the historic moment.The vehicle alarm of Xiao Shouing mostly is and sends chimes of doom on the car in the market, and this vehicle alarm has a lot of incomplete places, for example: when the people is in occasion indoor or that distance far or is comparatively made a lot of noise, often can't hear the stolen chimes of doom that sends of vehicle; And for example many cars are parked in a time-out, send chimes of doom simultaneously because of a variety of causes causes many cars, and whether the car owner is difficult to accurately judge chimes of doom is own vehicle, and in the course of time, people are accustomed to and produce decline in alertness, and this also is the stolen main cause of vehicle.
The utility model content
The utility model purpose is to provide a kind of automobile-used carry-on warning device easy to carry.
For achieving the above object, the utility model can be taked following technical proposals:
Automobile-used carry-on warning device described in the utility model comprises transmitter and receiver, and described transmitter comprises that promotion concussion radio-frequency transmissions circuit, signal encoding circuit, shock wave amplify delayed processing circuit and pulse shaping circuit; The output terminal that described shock wave amplifies delayed processing circuit and pulse shaping circuit is electrically connected with the input end of described signal encoding circuit respectively, and the output terminal of signal encoding circuit is electrically connected with the input end of described promotion concussion radio-frequency transmissions circuit; Described receiver comprises warning circuit when radio frequency reception amplification selective frequency filter circuit, signal decoding treatment circuit and signal Processing increase; Described radio frequency receives the output terminal that amplifies selective frequency filter circuit and is electrically connected with the input end of signal decoding treatment circuit, and the input end of warning circuit was electrically connected when the output terminal of signal decoding treatment circuit increased with signal Processing.
For improving the antijamming capability of receiver, the input end of warning circuit is electrically connected with the co-channel interference ripple and handles the time-delay controlling output circuit when described receiver signal processing increases, and the input end that described co-channel interference ripple is handled the time-delay controlling output circuit is electrically connected with the output terminal that selective frequency filter circuit is amplified in described radio frequency reception.
Pulse shaping circuit in the described transmitter is that 4 pulse per second (PPS)s form circuit, also can take the pulse shaping circuit at interval At All Other Times certainly.
Advantage of the present utility model is when vehicle meet to be stolen, and the vehicle that is moved self does not send chimes of doom and alarm that the car owner carries sends chimes of doom, and the people is in the indoor place that also can place the people to hear alarm.When vehicle is in a safe condition, alarm was given every several seconds and is sent once the safety sound of " ticking ", prove you vehicle nobody bump still in the original place, the safety sound that regularly sends " ticking " is also advantageous in that whether can judge alarm is in and can receives the zone that transmits, and is malfunctioning to avoid alarm.Because the input end of warning circuit is electrically connected with the co-channel interference ripple and handles the time-delay controlling output circuit when the receiver signal processing increases, therefore, when taking the radio co-channel interference as the high-tech car thief, the utility model can not stop issuing chimes of doom and be pointed out.
