基于组态技术的PC-PLC全自动洗衣机设计 摘 要 随着科技日新月异，人民生活水平不断提高，消费者对家庭电器自动化的需求不断加大，其中全自动洗衣机占很重要的位置。总体看来，高效节能、节水以及环保的全自动洗衣机一直在市场上占主导地位。 传统的洗衣机采用继电器控制，而大多数继电器的优点是装置结构简单、价格便宜、抗干扰能力强，但其容易损坏，产生噪音，耗能大。PLC的优点是：可靠性高，耗电少，适应性强，运行速度快，寿命长，为了进一步提高全自动洗衣机的功能和性能，避免传统控制的一些弊端，就提出了用PLC来控制全自动洗衣机这个课题。 本设计采用西门子公司的S7-200系列的PLC作为核心控制部件，利用其特点，对按钮、电磁阀、开关等其他一些输入/输出点进行控制，实现了洗衣机洗衣过程的自动化。本文对全自动洗衣机的控制系统进行了分析，进行了流程图和梯形图的设计，并进行仿真测试。为了能更直观的显示出整个自动控制过程，本设计运用组态MCGS软件建立了一个全自动洗衣机的监控系统画面。 关键词：PLC,核心,全自动,MCGS BY THE PC AND PLC BASED ON CONFIGURATION DESIGN OF THE AUTOMATIC WASHING MACHINE ABSTRACT Along with the rapid progress in science and technology, peoples living standards continue to improve, consumer demand for household appliances automation increasing, including fully automatic washing machine an important position. Overall, high efficiency and energy saving, water saving and environmental protection of the automatic washing machine has been dominant in the market. Most traditional washing machine controlled by relay, and relay device has the advantage of simple structure, cheap, strong anti-interference ability, but its easy to damage, noise, energy consumption. PLC is: the advantages of high reliability, less power consumption, strong adaptability, running speed, long life, in order to further improve the functionality and performance of the washing machine, avoid some disadvantages of traditional control, is proposed to use PLC to control the automatic washing machine is the subject. This design adopts the Siemens S7-200 series PLC as the core control components, with its characteristics, the button, solenoid valve, switch, or some other input/output point to control, realize the automation of the washing machine washing process. In this paper, the automatic washing machine control system was analyzed, and the flow diagram and ladder diagram design, and simulation test. In order to more intuitive shows the whole process of automatic control, the design by using the configuration software MCGS monitoring and co
