1、 I 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洗车机的控制系统。传统的方式是采用人工对车 辆进行清洗，这种方法劳动强度高、劳动效率低、对水和人力资源的浪费情况 比较严重，特别在遇到阴雨天气，车身沾满泥浆的时候，人工清洗不能满足对 车辆清洗速度的要求。 2 0 世纪 8 0 年代中期， 在公交系统的一些大型停车场 开始采用机械化的洗车方式， 但是由于技术的限制， 对汽车的清洗只能做
2、到半 人工化的工作， 即机器的所有动作还是要由人工操作完成， 对于提高效率的意 义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 PLC 进行控制，通过合理的选择和设计，提高了洗车机的控制水平。 利用 PLC 作为控制系统，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： 洗车机；PLC；逻辑控制；全自动 II ABSTRACT Science and technology in todays society is a rapidly developing soci
3、ety, 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

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
5、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 li

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 system
