The current domestic examination of the automobile synthesize function is only based on manual inspection or half-automatic inspection. So how to realize the fullautomatic inspection of the automobile synthesize function, that is quite attentioned by the corporation and academy who are very paying attention to the development of automobile inspection equipments at percent. Making use of modern electronics technique, computer and its network correspondence techniques, to develop the completely automatic vehicles overall performance inspecting line has become one inevitable trend. II. SUMMARY OF SYSTEM Automobile comprehensive performance test line is the testing system as a comprehensive use of modern detection technology, electronic technology, computer technology for automobile implementation nondismantlement testing and diagnostic testing. It can diagnose and test all kinds of vehicle performance parameter indoors , and detect malfunction status providing reliable basis for the comprehensive and accurate evaluation of performance and technique of car's situation. Automobile comprehensive performance lines can undertake the test of vehicle performance, reliability and safety of economy, environmental management etc, and can undertake the test of vehicle maintenance quality inspection and heavy-duty truck technology condition, using the test evaluation on the lines of industrial PC and weighing, brake, speed and exhaust gas, lighting, sound level as combined testing equipment, then form digital signal by adjusting and gathering each station equipment's signal, and transmit to mainframe automatically for host store, and form a complete test report according to the test results, and can provide function of inquiring statistical data and analysis, so as to realize the automation management of motor vehicle safety testing and information sharing with superior departments and related business department[1]. III. DESIGNING MENTALITY OF THE SYSTEM In order to succeed in the breakthrough of performance testing equipment assembly and online method, distributed computer test system will be applied in automobile comprehensive performance testing process. Then we will connect various testing equipments of respective operation modes and output data by computers, employing master computer and slave computer, to form a whole, then realize the concentrated automatic control and inspection the real-time data acquisition and processing, with the completion of each stage detection task rapidly, accurately and automatically[2]. System testing lines includes one master computer and three slave computer and a zero station machine, each slave computer is responsible for testing one operating station, and each operating station has at least two testing points. The first operating station mainly detects speed, tail gas and chassis. The second operating station mainly inspects braking performance by the axle load measurement platform and brake testboard.The third one operating station mainly measures engine performance, side slip, lighting, sound level, chassis dynamometer and other items. System composition diagram is shown in graph 1. Process of system inspection: Input and transmission of vehicles' information can be carried on in zero operating station, then single and system can collect judging and print detection results. Master computer is command and control center of all lines, and it compile machine information transmitted from zero station machine to form command word, then notify slave computer, and simultaneously summarize, sort out, calculate observing data from slave computer. © 2010 ACADEMY PUBLISHER AP-PROC-CS-10CN006 140
After the comprehensive performance testing, the final data is outputted to the printer, to print the report list and deposit in database for future query. It possesses at the same time high efficiency allowing several cars tested[3]. F. standard setting function Standards setting function the system can adapt to the state standards or change of local standards by modifying all testing items standard at any time. G. faults auto diagnosis and analysis function Computer networking detection system should be able to discover our own faults, and analyze and suggest the parts of the failure to help users for trouble-shooting. Namely, when the system is running, faults diagnosis' of mart CARDS, photoelectric switches, each sensor or circuit, etc should be suggested so as to ensure the normal running of the detection system[5].
