摘  要
    本文设计和构建了基于PLC的投币式自动洗衣机控制系统，投币结束后，选择相应的洗涤方式并完成自动洗衣机过程，主要用于解决校园、军营、工厂等人口集中居住场所方便快捷洗衣的需要。
    本文首先从理论上论述了投币式自动洗衣机的重要意义，讨论了投币方式的必要性与可行性，之后分析了自动洗衣机的机械结构和各种洗涤模式的工作过程，从而得出了以投币作为支付方式，选择不同的洗涤模式并完成洗衣过程的方法，结合PLC的有关知识，可设计出一套全自动洗衣过程控制系统。
 在上述理论研究的基础上，进行了投币式自动洗衣机控制系统的设计和研制。本文首先概述系统总体功能，并附以系统结构框图加以说明，着重介绍了本系统所采用的PLC类型和I/O口分配及工作过程,其次，详细阐述了程序控制流程和梯形图实现过程。本设计以数字集成电路技术为基础，PLC技术为核心。本文编写的主导思想是软硬件相结合，以硬件为基础，来进行各功能模块的编写。

 This paper designs and composites the control system for coin operated automatic washing machine based on PLC. It chooses the right washing methods after slipping coins into the coin operated automatic washing machine and then completes the washing process.
 This paper first theoretically discusses the importance of coin operated  automatic washing machine ,discusses the necessity and feasibility of coin approach, then analysis the structure and patterns of work processes of automatic washing machine, thus obtained to the number of coin-operated washing mode and select the appropriate way to complete the laundry process, combined with PLC's knowledge, we can design an automatic laundry process control system.
 Based on the theoretical study, automatic washing machines were coin-operated control system design and development. This paper first outlines the overall function of the system, then attached to the system block diagram to illustrate, highlights of the system used by PLC type and I / O port allocation and working process,
 Second, it discusses the detail of the program control flow and ladder realization. The design of digital integrated circuit technology-base.PLC technology as the core. This article is written in the guiding combination of hardware and software to hardware-based, to the preparation of various functional modules.
 Key Words: PLC, Washing machine, Coin-operated, Automatic control
