摘要
首先介绍了自动售货机的结构组成,简述了利用可编程序控制器(PLC)控制的自动售货机控制系统的控制原理,最后给出了该控制系统的软硬件设计,并编写了系统程序总框图和一个具体的梯形图,经实践验证该控制系统是可行的.
The basic elements of a vending machine are introduced in this paper. The control fundamental of the vending machine control system based on PLC are also described. The hardware and software design of the control system is given. The block diagram of the system software is designed and the specific ladder diagram is also programmed. This control system has been proven feasible in practical applications .
