ABSTRACT
As the amount of car increases very quickly, the service trades of car are facing a very important chance. Because Car washer is the most important equipment in the process of washing car, these questions must be reflected on in the process of the design and the manufacture of the automatic car washer, such as the effect of washing car, the efficiency of washing car, the cost of washing car, the protect of environment, and so on.
In this side, according to the analysis of the function and the operating process of car washer, the overall plan of design is determined(The detail design of the driving
and controlling system of car washer are designed, according to the characteristics of the automatic car, it adopts some processes, such as the vaginal spray, spray cleaning agent, brushing, air drying and so on. In the control system，it adopts the technology
of sensor and PLC to design the composition of PLC hardware and program the controlling software(The controller is Mitsubishi FX2N series PLC and the program is ladder program, it meets the requirements of the operating and controlling and also the demands of the efficiency, the cost and protect of the environment.
Key words: automatic car, PLC, controlling system, ladder program, hardware and software program
