全自动洗车库的电气控制
摘要:全自动洗车库是一种通过电脑设制相关程序来实现自动清洗、打蜡、风干清洗轮辋等工作的机器。本文主要通过对全自动洗车库的功能要求和运行过程的分析,确定了全自动洗车库的总体设计方案。着重对洗车库驱动和控制系统进行了设计。针对洗车库的特点,主要采用了电力驱动方式。在控制部分,应用了传感器和可编程控制技术,对洗车库PLC控制系统进行了硬件设计和软件编程。由于PLC的方便可靠性使得控制系统简单明了,抗干扰能力强,省去大量的中间继电器,时间继电器。接线简单,在洗车工艺过程要求变动时只需改变软件程序即可,使设计周期相应的大大缩短,因此用PLC来设计自动洗车库的一个理想的控制工具。PLC选用西门子公司生产的S7—200系列可编程控制器,采用梯形图(LD)编程语言,完全能够满足洗车库的控制要求,实现了用PLC代替常规继电器。
本文首先对本课题进行简要的介绍,包括背景,研究意义,现状等;其次详细阐述了汽车库的总体设计方案,各个工作机构的运行分析和功能要求;再次对该系统的硬件组成、结构、选型进行了阐述和分析;最后利用梯形图(LD)和语句表(STL)进行PLC程序的编写,并对设计本课题所学到的知识和结论进行归纳和总结。

Electrical Control Design Of
Automatic Car Washing Library
Abstract: Automatic car wash library is puter based system procedures to achieve the self-cleaning, waxing, air-dry cleaning rims and other machine. In this paper, through analysis of the functional requirements of the automatic car wash library and running, to determine the overall design of the automatic car wash library. Focuses on washing library drive and control system design. For the characteristics of the car wash library, the main electric drive. In the control section, the application of sensors and programmable control technology, the car wash library PLC control system hardware design and software programming. PLC convenience and reliability makes the control system is simple and clear, strong anti-jamming capability, eliminating the need for a large number of intermediate relay, time relay, simple wiring, simply by changing the software program in the washing process requires a change can make the design cycle greatly shortened PLC to design the automatic car wash library is an ideal tool of control. PLC selected the Siemens S7-200 series programmable controllers using ladder programming language can be a good drive and control requirements of the automatic car wash library to
