Main application mapping and industrial safety-security area, the every aspects for appearing in life more and more in recent years.
It is used for carrying out the equipment of adjacent lane monitoring on the market at present during vehicle lane change mainly by camera, super
Sound radar and pseudo millimeteric wave radar are realized.In the process of moving, whether inspection closes on track has the vehicle close or just to vehicle
Travel on lane change danger zone.Object detection system based on camera is generally mounted to below vehicle mirrors, based on microwave
Rear view of vehicle is often installed on close to the position of both sides with the object detection system of ultrasonic wave.On vehicle track is done using camera
During monitoring, heavy dependence ambient light conditions, effect is poor in the bad environment of the light such as night；Ultrasonic radar does hazardous area
Domain monitors, and operating distance can only have two meters of effects, can not effectively detect vehicle week region large-scale enough；Using microwave radar
Monitoring radar system, compared to ultrasonic radar, operating distance can be significantly increased, improve vehicle lane change safety coefficient.But
For microwave radar since the microwave beam that it emits is wider, target bearing identification is inaccurate.

Several are beamed into through preposition light-splitting device and is arranged in a row subdivided beams, and angle is 0.2-2 degree between light beam；
S2：Laser beam is emitted with fixed frequency, and when its irradiation area has vehicle target, fraction of laser light signal will reflect
The system of returning, the received light path of reflection echo signal converge to corresponding detector after receiving, and by detector arrangement and emit laser
Vehicle lane change danger zone is divided into multiple monitoring sections to be monitored respectively by row；
S3：In the presence of having target when some region, after corresponding detector receives echo-signal, light is carried out to echo-signal
Electricity conversion, obtained electric signal obtains laser from the time difference for being emitted to reception through processing circuit measurement, corresponding so as to obtain
Target range；
S4：With reference to obtained distance and known direction angle information, orientation where target is determined.
Further, display device is the LED that a row is installed on beside vehicle mirrors, and governor circuit is according to different zones
Interior different target distance, calculates the danger classes of lane change environment, and LED arrangements warn different danger etc. respectively from inside to outside
Grade provides more accurate warning information to driver.
Patent of the present invention due to using the technology described above, can obtain following technique effect：Relative to the prior art
In the anti-collision system based on camera, laser radar is a kind of active detection system, by itself sending out laser and receiving mesh
Echo is marked, independent of external light source, can effectively worked in daylight and at night；Laser radar system is referred in high precision using laser beam
To the characteristics of, emitted energy is more concentrated, and farther distance can be measured compared to ultrasonic radar.
Compared to the big field angle of microwave radar, the direction advantage of laser radar can more accurate measurements close on track situation simultaneously
Measurement target signature that can be finer is provided for driver vehicle's lane change action and is more accurately prompted；Multiple-input multiple-output type laser thunder
The optical mechaical scanning mechanism of conventional laser radar is omitted up to system, system bulk can be reduced, while multiple regions can be monitored,
More accurate road information is provided to driver, no moving component makes system have higher operational reliability.
