摘  要
    本文設(shè)計(jì)和構(gòu)建了基于PLC的投幣式自動(dòng)洗衣機(jī)控制系統(tǒng)，投幣結(jié)束后，選擇相應(yīng)的洗滌方式并完成自動(dòng)洗衣機(jī)過程，主要用于解決校園、軍營、工廠等人口集中居住場所方便快捷洗衣的需要。
    本文首先從理論上論述了投幣式自動(dòng)洗衣機(jī)的重要意義，討論了投幣方式的必要性與可行性，之后分析了自動(dòng)洗衣機(jī)的機(jī)械結(jié)構(gòu)和各種洗滌模式的工作過程，從而得出了以投幣作為支付方式，選擇不同的洗滌模式并完成洗衣過程的方法，結(jié)合PLC的有關(guān)知識，可設(shè)計(jì)出一套全自動(dòng)洗衣過程控制系統(tǒng)。
 在上述理論研究的基礎(chǔ)上，進(jìn)行了投幣式自動(dòng)洗衣機(jī)控制系統(tǒng)的設(shè)計(jì)和研制。本文首先概述系統(tǒng)總體功能，并附以系統(tǒng)結(jié)構(gòu)框圖加以說明，著重介紹了本系統(tǒng)所采用的PLC類型和I/O口分配及工作過程,其次，詳細(xì)闡述了程序控制流程和梯形圖實(shí)現(xiàn)過程。本設(shè)計(jì)以數(shù)字集成電路技術(shù)為基礎(chǔ)，PLC技術(shù)為核心。本文編寫的主導(dǎo)思想是軟硬件相結(jié)合，以硬件為基礎(chǔ)，來進(jìn)行各功能模塊的編寫。

 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
