Abstract This article introduced vending machine's basic principle aswell asthe work flow, Introduces the basic principle ofvending machines and work flow, and then toatransaction process, for example, the process isdivided into several blocks, then respectively for program for programming take atransaction process asexamples, divides into several blocks the transaction process, then carries onthe programming separately tothe block. Explained the programmable controller's invending machine function specifically. The procedure involved the vending machine work major part process. Enhanced system's stability using the PLC control's vending machine, the guarantee vending machine has been able the long-term stability movement. key words :vending machine; Programmable controller; Trapezoidal chart 充值下载即送 CAD 图纸, QQ 36396305 答辩无忧,值得下载! 目录摘要..............................................................................................................................
