汽车自动清洗机控制系统设计 摘要 文章对我国发展低成本自动化的重要性等方面进行了研究。以自动汽车清洗机为对象，探讨了全自动汽车清洗机智能控制系统的实现方案。根据实际需要和市场的需求，在常规的可编程控制器（PLC）和单片机控制中，选择了以可编程控制器为主的控制方案。 根据自动清洗机的工艺过程和控制要求，采用三菱FX2N型号可编程序控制器设计了自动洗车机的控制系统。它要求其控制设备具有很强的抗干扰能力，而PLC是近几年发展起来的一种新型工业控制器。由于它把计算机的编程灵活、功能齐全、应用面广泛等优点与控制器系统的控制简单、使用方便、抗干扰能力强、价格便宜等优点结合起来，而其本身又具有体积小、重量轻、耗电省等特点，在工业过程控制中的应用越来越广泛。 文章中采用了以工业顺序控制过程中广泛使用的可编程控制器（PLC）对自动洗车机进行控制。通过对自动洗车机的工作原理的分析，提出总体设想，初步设计了电气控制部分的设计方案和PLC控制的程序流程图。 关键字：可编程控制器；自动控制；顺序控制；自动洗车机 CONTROL SYSTEM OF PROGRAMMABLE CONTROLLER USED IN AUTOMATIC CAR WASHERS Abstract Article develop to our country low cost automatic importance，etc. respect carry on research. Regard industrial board cutting machine as target, probe into full-automatic to can cut board quick-witted realization scheme of the control system. According to the real demand of and the market, in the regular programmable controller (PLC) and one-chip computer control, have chosen the control scheme relying mainly on programmable controller. According to the technological process and control requirements of the automatic car washer，a FX2N programmable controller is applied in the control system of that washer. It requires its apparatus of control to have very strong anti-interference ability, and PLC is the controller of a kind of infant industry developed in recent years. Because the programming of a pair of computer of its is flexible , and controller control of system simple easy to use, anti-interference ability strong, price getting cheap advantage combined together, and it has characteristics such as small, light, power consumptive provinces etc., the application in the industrial process is controlled is more and more extensive. Article adopt in industrial order controlling programmable controllering (PLC ) that course using extensively to automatic car washer control automatically. Through to cutting the analysis of the operation principle of the board machine automatically, put forward the general program, have designed the procedure flow di
