基于 PLC 的全自动洗衣机控制系统摘要：本文首先介绍了可编程控制器（PLC）的结构和功能，以及全自动工业洗衣机的结构，然后分析和研究了全自动洗衣机控制系统的工作原理。在此基础上，结合工作需要，提出了以 PLC 为控制核心部件进行全自动洗衣机控制系统的设计。然后，从全自动洗衣机六个工作过程出发，对系统控制方案进行了可行性分析和论证，包括 PLC 以及外围设备选型、编程方式选择、各种抗干扰措施等。最后设计了以西门子 S7-200 系列 PLC 为控制核心的全自动工业洗衣机控制系统，包括了控制系统的 I/O 端口分配、PLC 接线图及 PLC 程序设计，并详细分析了程序的控制过程，实现了洗衣机洗衣过程的自动化，具有智能化程度高安全可靠、方便、灵活等特点。关键字：工业洗衣机 PLC 控制系统 设计Automatic washing Machine Control system based on PLCAbstract:This paper first introduces the structure and function of programmable logic controller (PLC) and the structure of automatic industrial washing machine, and then analyzes and studies the working principle of the automatic washing machine control system. On the basis of this, the design of automatic washing machine control system based on PLC is put forward. Then, starting from the six working processes of the automatic washing machine, the feasibility of the system control scheme is analyzed and demonstrated, including the selection of PLC and peripheral equipment, the selection of programming mode, and various anti-interference measures, etc. Finally, a fully automatic industrial washing machine control system based on Siemens S7 / 200 series PLC is designed, which includes the I / O port assignment, PLC wiring diagram and PLC program design of the control system, and the control process of the program is analyzed in detail. The automation of washing machine is realized. It has the characteristics of high intelligence, safe and reliable, convenient, flexible and so on.Keyword:D...
