Abstract
With the rapid development of the road construction and road transport,the vehicle detector industry is also growing;at the same time,the higher requirment for the car comprehensive performance test station is also being promoted by transportation development,from the technical service quality.With the development of the auto industry,the safe driving of vehicles has attracted increaing attention.Therefore,as stipulated in motor vehicle low both at home and abroad,the optical properties of thevehicle is compulsory standards.It is very necessary for research vehicle lamp with optical detection system who have many virtues such as low cast、high-precision and intelligent. The accuracy is high and the intelligence is carried out.The text describes the design of project and the software processes of the electric circuit,in terms of hardware system,carries on research and designs mainly from the collect of signal,the electric control.
