Abstract
The utility model relates to an overtaking signal device. The utility model adopts the method of infrared frequency modulation lamp signal, so the noise which is generated by the old whistling overtaking signal and the disturbing influence signal can be overcome, and the utility model is has the following advantages: high sensibility, good anti-interference ability, good vibration resistance ability, strong reliability, simple structure and small volume, etc than the new tentative actinoelectricity overtaking signal and the infrared overtaking signal.
Description
The utility model relates to a kind of infrared frequency modulation signal device.
The increased anxiety of traffic, reduce since in the past during automobile overtaking the used loudspeaker stereo pickup electrode of blowing a whistle be subject to noise jamming and the unreliable improper accident that causes of overtaking other vehicles that causes, with the blow a whistle city noise influence of loudspeaker stereo signal of reduction, very urgent.The mode that adopts photosignal and infrared signal to transmit the signal of overtaking other vehicles all begins tentative and some shortcomings is all arranged.
The utility model adopts the mode of infrared frequency aeolight signal, than existing mode have more that highly sensitive, good in anti-interference performance, anti-seismic performance are good, advantage such as good reliability, volume simple in structure are little.Sender unit of the present utility model is to adopt the power supply of the original country beam of automobile is carried out the modulation of infrared frequency, not quite do not influence with 800HZ AM single-side-band value, so can guarantee the reliable continuously of signal for the calorific effect of filament lamp; Only need increase a very little modulating device in original car bulb loop, it is simple and reliable to increase the mode that sends photosignal or infrared signal isolated plant than other.The existing device that adopts photosignal, silicon photovoltaic cells is subjected to Temperature Influence bigger; Because anti-shake performance poor reception device can not all be installed in automobile tail, after partly being converted to electric signal with optical signal, the reception of the tailstock is sent to automotive front, be easy to be interfered; The device that has (as the CAH-863A type) also needs device and automobile are insulated.The existing device that adopts infrared signal need be set up whole infrared ray transmitting and receiving devices, and not only investment is many, and technical performance is generally reliable not as electrical equipment.
Embodiment of the present utility model:--
Projector partly as shown in Figure 1, F

1Be the very strong CMOS integrated oscillator circuit of obstacle overcome ability, making car direct current power supply produce the 800HZ dutycycle through vibration is 40% square wave, Integral Processing becomes the near sinusoidal pulse, its voltage-to-current amplifying circuit is realized with VMOS and Darlington transistor, boost by voltage transformer B and to produce 12 volts 15 pulse power of pacifying of effective value, be added on the original country beam power supply of automobile itself through isolation diode D again and produce the light of infrared frequency amplitude modulation, lamplight brightness changes the very faint calorific effect that does not also influence incandescent filament, so the car light and the signal of overtaking other vehicles all can continuous dependable services.
Partly shown in accompanying drawing 2, accompanying drawing 3, photosensitive diode GD receives the signal of overtaking other vehicles that front vehicle is sent to receptor through infrared ray; Pick up behind the ripple by block isolating circuit the modulated infrared signal of its alternation is amplified, (this partly finishes by integrated component GDQ, and the element of cooperation comprises C with amplifying and change into direct current signal behind the noise beyond the bandpass filter filtering 800HZ again
