After appears, the utility model enables the automobile running in highways to do prepare in advance when the automobile encounters the occurrence of traffic troubles in front of the automobile, avoids the tail end collision of following automobiles, and enables the life and property of people to suffer less. The utility model has the advantages of simple structure, convenient use, accurate warning, safety, reliability, etc.
Description
The utility model belongs to the vehicle safety travel accessory equipment of communications and transportation.
Along with the development of communication, the quantity of various automobiles is all increasing severely with day, expressway construction, and flow, the speed of automobile all increase substantially.The thing followed is exactly the collision of knocking into the back of common occurrence on the express highway, that happen occasionally, brings about great losses for people's life and national wealth.In patent documentation, can see the vehicle safety travel controller that discloses, they mostly are to adopt infrared transmitting tube forwards to launch infrared wave to survey the place ahead obstacle, to run into signal that obstacle reflects then after receiving, handling, and force automobile flameout to stop.Nos oriented long-distance alarm device of sort controller itself, as the vehicle of running at high speed later, chaufeur is not observed the place ahead vehicle, when near the time in case discovery take measures just to come too late.Make the incident of colliding continuously be difficult to avoid.
The purpose of this utility model provides a kind ofly can assist chaufeur, and just knowing in certain distance has automobile accident to take place on the road ahead, and it is taken measures, and exempts the warning device that bumps against with the vehicle that exceeds line-of-sight distance.
Technical essential of the present utility model is:
It comprises by the slide block type sensor, select radiating portion that acoustic-electric road, language circuit, audio modulating circuit, power amplification circuit constitute and the receiving unit that is made of pre-amplification circuit, demodulator circuit, audio amplifier circuit.When changing, the speed in unit time of vehicle ' surpasses threshold values, the slide block of slide block type sensor moves, touch its switch closure, provide electric signal, through select switch to selecting acoustic-electric road or analogous language circuit to produce alarm sound or speech signal, the pulse-modulated signal that send audio modulating circuit formation pulse width and sound signal to be directly proportional, power amplification circuit is launched in the air by the sky alignment after amplifying.The vehicle of receiving unit is housed, will receives modulation signal, export demodulator circuit to through the pre-amplification circuit amplification and provide sound signal, send audio amplifier circuit and produce sound equipment or analogous language signal through loudspeaker from antenna.The sensor mouth of radiating portion connects by select switch K
