Abstract
This article briefly introduces the development of automat, and briefly analyses the automat’s basic functions and working methods, it designs a control system of automat based on PLC in allusion to the advantages and advantages of automat control system.
This design uses the CPM2A which developed by the Japanese OMRON Company realizes to automat’s automatic control. It has designed 1 Yuan, 5 Yuan and 10 Yuan three kinds of throw the coin way, in the automat has 2 Yuan and 3 Yuan two kinds of commodities. When the investment currency value is more than or equal to the commodity price, then may purchase this commodity. If there is remaining money in the automat, you can withdraw money from it. This design has realized the currency automatic addition, subtraction and the comparison function. Finally, the Star configuration software is used to monitor the operation of the screen, so the work process of automat can be more intuitive to present.
This article focuses on the program design of PLC and making the configuration interface. When I design the PLC program, I introduce The Modular Design ideas. I take analysis separately according to the internal work processes of automat. Therefore, the system is characterized in simplicity and convenience of understanding, looking up and debugging, and is able to satisfy all the work indicators required by automat. It can be applied in practice.

Keywords: PLC; Automat; T-figures

摘 要
   本文簡(jiǎn)要介紹了自動(dòng)售貨機(jī)的發(fā)展現(xiàn)狀，又簡(jiǎn)要分析了自動(dòng)售貨機(jī)的基本功能及工作方式。針對(duì)現(xiàn)在自動(dòng)售貨機(jī)控制系統(tǒng)的優(yōu)缺點(diǎn)，設(shè)計(jì)了一個(gè)基于PLC的自動(dòng)售貨機(jī)控制系統(tǒng)。
本設(shè)計(jì)使用日本歐姆龍公司開發(fā)的CPM2A可編程控制器實(shí)現(xiàn)對(duì)自動(dòng)售貨機(jī)的控制，設(shè)計(jì)了1元、5元和10元三種投幣方式，自動(dòng)售貨機(jī)內(nèi)有2元和3元兩種商品，當(dāng)投入幣值大于或等于商品價(jià)格時(shí)，則可以購買該商品。當(dāng)自動(dòng)售貨機(jī)內(nèi)還有剩余錢額時(shí)，則可以實(shí)現(xiàn)退幣功能。設(shè)計(jì)實(shí)現(xiàn)了貨幣的自動(dòng)加、減和比較功能。最后用世紀(jì)星組態(tài)軟件進(jìn)行監(jiān)控系統(tǒng)的運(yùn)行畫面，使自動(dòng)售貨機(jī)的工作過程可以更直觀的展現(xiàn)出來。
本文的重點(diǎn)放在PLC程序的設(shè)計(jì)和世紀(jì)星組態(tài)界面的制作。在進(jìn)行PLC指令設(shè)計(jì)的時(shí)候，采用了模塊化的編程思想進(jìn)行設(shè)計(jì)，按照自動(dòng)售貨機(jī)系統(tǒng)的內(nèi)部工作過程來單獨(dú)進(jìn)行分析。因此該系統(tǒng)具有理解較容易，查找代碼及調(diào)試方便等特點(diǎn)，并且能很好的達(dá)到自動(dòng)售貨機(jī)的各項(xiàng)控制性能指標(biāo)，可以在實(shí)際中進(jìn)行應(yīng)用。
