【正文】 gram, I introduce The Modular Design ideas, Use of the ladder diagram programming approach. 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. Finally,The kingview configuration software is used to monitor the operation of the screen, so the work process of automat can be more intuitive to present. at the same time saving development costs of the automat. Key words: PLC。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，并 且能很好的達到自動售貨機的各項控制性能指標，可以在實際中進行應(yīng)用。 本文的重點放在 PLC程序的設(shè)計和組態(tài)王 組態(tài)界面的制作。 基于 PLC 自動售貨 機 控制 系統(tǒng)設(shè)計與仿真 基于 PLC 自動售貨機控制系統(tǒng)設(shè)計與仿真 摘 要 本文簡要 介紹 了自動售貨機的發(fā)展現(xiàn)狀 ，又簡要分析了自動售貨機的基本功能及工作方式。針對現(xiàn)在自動售貨機控制系統(tǒng)的優(yōu)缺點， 設(shè)計了一個基于 PLC的自動售貨機控制系統(tǒng) 及 用組態(tài)王對 其仿真 。 在進行 PLC程序設(shè)計的時候， 利用了梯形圖的編程方式， 采用了模塊化的編程思想進行設(shè)計，按照自動售貨機系統(tǒng)的內(nèi)部工作過程來單獨進行分析。 最后用組態(tài)王組態(tài)軟件進行監(jiān)控系統(tǒng)的運行畫面的仿真，使自動售貨機的工作的每一過程可以更直觀的展現(xiàn)出來，同時節(jié)約了自動售貨機的開發(fā)成本 和不必要的開發(fā) 原材料 浪費 。
