基于PLC的自动洗车控制系统设计 摘要 当今社会是一个科技高速发展的社会，是一个自动化盛行的社会。有人开玩笑地说，自动化技术是聪明人为懒人发明的技术。这句话的前半句是有些道理，后半部分就不太确切了。因为自动化技术的发明和发展并不是用来为懒人服务的。??? 本课题设计了一个全自动控制系统。全自动洗车机是人机为一体的自动化洗车设备。大大提高了洗车质量和洗车效率。采用进行控制，通过合理的选择和设计，提高了的控制水平。利用PLC控制，已成为当今制造业领域进行设备革命、提高生产力和市场竞争力的重要手段。特别是生产的自动化改造，PLC控制已成为一种技术潮流之一。 关键词逻辑控制 全套图纸，加 ABSTRACT Science and technology in todays society is a rapidly developing society, is the prevalence of an automated society. It was a joke to say that automation technology is smart technology invented by lazy people. This sentence is some truth in the first phrase, the latter half of the less precise. Because of automation technology is not the invention and development of services for the lazy. ????? This issue we designed a fully automatic washing machine control system. The traditional approach is the use of artificial cleaning of vehicles, the method of high labor intensity, labor efficiency is low, water and waste of human resources is very serious, especially in case of rainy weather, the body covered with mud, the manual cleaning can not be the speed of vehicles to meet the cleaning requirements. 2 0 century and the mid-eighty, in the public transport system a number of large-scale parking lots began to use mechanized methods of washing, but due to technical limitations, the cleaning of the car can do the work of semi-artificial, that is, all the machine movements or to be completed by manual operation, for improving the efficiency of the significance of fully automatic washing machine is one machine for the automated car wash equipment. Greatly enhance the quality of the car wash and car wash efficiency. The use of PLC control, through the rational selection and design, raised the level of control washing machine. As the use of PLC control systems, has become the area of equipment manufacturing industry revolution, increasing productivity and market competitiveness of an important means. In particular the transformation of production automation, PLC control tec
