摘 要
無人售貨機(jī)是由勞動密集型的產(chǎn)業(yè)構(gòu)造向技術(shù)密集型社會轉(zhuǎn)變的產(chǎn)物。進(jìn)入21世紀(jì)時,無人售貨機(jī)也將進(jìn)一步向節(jié)省資源和能源以及高功能化的方向發(fā)展。利用PLC控制的無人售貨機(jī)提高了系統(tǒng)的穩(wěn)定性,保證無人售貨機(jī)能夠長期穩(wěn)定運(yùn)行,且控制系統(tǒng)結(jié)構(gòu)簡單功能完善、通用性強(qiáng)、體積小,維護(hù)操作方便而且易于實現(xiàn)網(wǎng)絡(luò)化。本文主要對無人售貨機(jī)的控制系統(tǒng)進(jìn)行了程序設(shè)計,并列出了控制系流程圖以及梯形圖。

Design of the Dispenser Control System base on PLC
Abstract
The digest this text has introduced the basic principle and workflow of the dispenser , then take transaction course as an example , divide the trade course into several procedure ones, then carry on programming to the procedure one separately. It has stated the role in dispenser of the controller of can programme ing that concrete. The procedure has involved most course that the dispenser worked. The dispenser utilizing PLC to control has improved systematic stability, it can be steady in a long-term to guarantee the dispenser and run.
