摘   要
 隨著公路建設(shè)和道路運(yùn)輸事業(yè)的迅猛發(fā)展, 為汽車正常運(yùn)行提供技術(shù)支持的車輛檢測(cè)行業(yè)也隨之不斷發(fā)展壯大; 同時(shí), 汽車運(yùn)輸業(yè)的發(fā)展又對(duì)車輛綜合性能檢測(cè)站的檢測(cè)技術(shù)、服務(wù)質(zhì)量提出了更高要求和期望。隨著汽車、摩托車工業(yè)的發(fā)展，車輛的安全行駛?cè)找嬉�起人們的關(guān)注。因此，國(guó)內(nèi)外均將有關(guān)車輛的配光性能列為汽車法規(guī)或強(qiáng)制性標(biāo)準(zhǔn)檢測(cè)項(xiàng)目。作為檢測(cè)車燈配光性能的各種智能檢測(cè)系統(tǒng)或裝置，根據(jù)實(shí)際需要，研制一種低成本、高精度的智能化車用燈具配光檢測(cè)系統(tǒng)，是非常必要的。本次設(shè)計(jì)的系統(tǒng)精確度高且實(shí)現(xiàn)了智能化。本論文主要敘述電路的設(shè)計(jì)方案和軟件流程，在硬件方面，主要從信號(hào)采集，電氣控制等方面進(jìn)行研究和設(shè)計(jì)。

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.
