l 基于自动洗车机的PLC系统的设计 摘 要 随着我国汽车保有量的迅速提高，汽车清洗行业迎来了一个重要的发展机遇，自动洗车机作为洗车工作必不可少的设备，其清洗效果，清洗速度，清洗成本以及对节水和环境保护的要求，成为其开发和生产必须要考虑的内容。 本文主要通过对自动洗车机功能要求和运行过程的分析，确定了自动洗车机的总体设计方案。主要进行了自动洗车机的驱动和控制系统的设计，针对自动洗车机的特点，采用喷水，洗刷，喷洒清洗剂和风干等过程，在控制部分，应用传感器和可编程序控制器技术，对汽车清洗机PLC控制系统进行了硬件设计和控制软件编程。PLC选用三菱公司生产的FX2N系列可编程序控制器，采用梯形图编程语言，实现了汽车清洗机的传动和控制要求，满足了环保、高效、可靠和低成本的要求。 关键词：自动洗车机，PLC，控制系统，梯形图，硬件及软件 Management System For automatic car washing machine ABSTRACT As the amount of car increases very quickly, the service trades of car are facing a very important chance. Because Car washer is the most important equipment in the process of washing car, these questions must be reflected on in the process of the design and the manufacture of the automatic car washer, such as the effect of washing car, the efficiency of washing car, the cost of washing car, the protect of environment, and so on. In this side, according to the analysis of the function and the operating process of car washer, the overall plan of design is determined．The detail design of the driving and controlling system of car washer are designed, according to the characteristics of the automatic car, it adopts some processes, such as the vaginal spray, spray cleaning agent, brushing, air drying and so on. In the control system，it adopts the technology of sensor and PLC to design the composition of PLC hardware and program the controlling software．The controller is Mitsubishi FX2N series PLC and the program is ladder program, it meets the requirements of the operating and controlling and also the demands of the efficiency, the cost and protect of the environment. Key words: automatic car, PLC, controlling system, ladder program, hardware and software program 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc312165486 摘 要 PAGEREF _Toc312165486 \h I HYPERLINK \l _Toc312165487 ABSTRACT PAGEREF _Toc312165487 \h II HYPERLINK \l _Toc312165488 目 录 PAGEREF _Toc312165488 \h III HYPERLINK \l _Toc312165489 第1章 绪论 5 HYPERLINK \l _Toc312165490 1.1 概述 5
