Therefore generation.
Infrared ray carries out detection to barrier and has the advantage that
Infrared ray has the strongest penetration capacity, can make in the adverse circumstances such as haze, rain, snow, foggy weather, night
With；
Pulsed infrared light spread speed is fast, and light frequency rate of decay in communication process is relatively slow, and infrared ray can effectively detect
The barrier in a distant place, stability is strong；
The intensity of pulsed infrared can be adjusted, and then the maximum coverage of regulation detection.
Infrared detection device simple in construction, volume are little, expense is low, being easily integrated and miniaturization；
Therefore, infrared detecting method is the most increasingly paid attention to by people, and infrared detecting method is stable, accuracy is high, extensively should
For the field such as acquisition of signal, fire monitoring.
Utility model content
The purpose of this utility model is that pilot's line of vision on current road is bad or driver neglects and causes in order to solve
The problem of vehicle accident, calculates the vehicle distance away from barrier, and reports to the police, call user's attention safety；Overcome existing
Obstacle detection product and system cost are high, and design is complicated, intellectuality is low, investigative range is little, degree of accuracy is the highest, poor for applicability etc. lacks
Point, it is provided that a kind of convenient to operate, installation, economic, accurate, stable, safe and reliable a kind of based on infrared detection technique automobile
Obstacle detection early warning system.

Single-chip microcomputer, for receiving the infrared signal launched, the infrared remote receiver feedback that infrared transmitter feedback comes
Come over received reflected light signal；Calculate infrared transmitter transmitting infrared ray according to optical time domain reflection principle formula to connect with infrared
Receive the time interval of device receiving infrared-ray, and then calculate the automobile distance to barrier, finally according to speed and time relationship
Alerting drivers or control pull device braking vehicle；
Pull device, for braking vehicle；
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of obstacle vehicle detection early warning system based on infrared detection technique, including: buzzer, control panel, infrared
Emitter, infrared remote receiver, single-chip microcomputer, pull device, it is characterised in that: launch power by regulation infrared transmitter, adjust
Joint infra-red detection scope, when infrared remote receiver receives the infrared ray reflected from obstacle vehicle thing, infrared remote receiver will
Information passes to single-chip microcomputer, and single-chip microcomputer automatically processes information, calculates infrared transmitter according to optical time domain reflection principle formula and launches
Infrared ray and the time interval of infrared remote receiver receiving infrared-ray, and then calculate automobile to obstacle according to speed and time relationship
The distance of thing, last alerting drivers or control pull device braking vehicle；
The operation principle of this obstacle vehicle detection early warning system based on infrared detection technique is: front opening control in road on automobile
Making the switch that infrared obstacle detection early warning system starts, driver rotates the knob of regulation early warning range as required, and knob is even
Connecing control panel, the transmitting power of control panel and then control infrared transmitter is to control ultrared intensity, and then controls institute
Launching the ultrared effective propagation distance coverage with control detection, investigative range divides 20m, 50m, 100m, 150m, 200m
Five shelves；Narrow infrared light pulse launched by infrared transmitter, and the ultrared signal launched is passed to single-chip microcomputer, and infrared ray exists
