Under the circumstances of rapid development of automobile industry ,as well as the increase of the auto possession, car maintenance industry has won fast progress as well, which leads to fierce competition among enterprises to meet the competitive challenges of car maintenance market in domestic. At present, there are many shortcomings with regard to domestic car washer equipment performance, such as not stable enough, high failure rate, plagiarized exterior design and rough performance, etc.. Against the background of Siemens WinCC, the paper give comprehensive analysis about the technological characteristics, technical parameters and control difficulties of automatic car washing process. Then, we can determine the automatic control scheme and conduct system simulation, joint debugging and operation about the automatic car-washing control system. We have Complete the task of flow chart drawing, database establishment, dynamic link, screen switching and the design of fault and alarm system of the automatic car-washing control system. Furthermore, we have achieved the goal of au
