Abstract
As the amount of cars increases very quickly, the service trades of car are facing a very important chance. Car washer is the most important equipment in the process of washing car. It is important to develop automatic car washing machine for conserving water resources and environmental protection, improving their efficiency.
In the design of this project, according to analyze the function requirement and the operating process of automatic car washing machine, the overall scheme of the automatic car washer. The detail design of the driving and controlling system of car washer is designed. According to the characteristics of automatic car washing machine, this paper adopted the motor to driving system. In the control system, adopted the technology of sensor and PLC, designed position of PLC hardware and programmed the controlling software. The PLC controller adopted pany produces S7-200 series programmable controller, using a ladder diagram programming language, realized the driving and controlling requirements, meet the demand of the efficiency, environmental protection, safety, reliability and low cost requirements.
This paper mainly discusses the following contents:
cleaning machine of automobile overall design;
of automatic cleaning machine of automobile electrical system;
of PLC control system of the automatic cleaning vehicle, which includes hardware design and software design.
Key words: Automatic Cleaning Machine for Vehicle; Motor; Circuit Diagram; Programmable Logic Controll
