基于plc和组态王的自动售货机控制系统的设计正文大学学位论文.doc

编程软件对售货机的售货过程进行了程序编写，并在组态王 6.55 上进行模拟交

易的仿真。设计中主要实现了普通售货机的基本功能，其包括投币累加、钱币不

足提示、退币提示、选择购买商品以及自动结算等功能。设计系统中，一次只能

购买一种商品，为了不发生程序错误，在其中设计了较多了互锁。其整个功能的

实现均可在组态王上进行模拟交易。

and the concept of shopping, vending machine provides us with a lot of

software of the vending machine sales process of programming, and

simulated trading simulation on Kingview 6.55. The design mainly realizes

the basic function of ordinary vending machine, which comprises a coin

accumulation, coin shortage prompted, coin tips, choose to buy goods and

automatic billing and other functions. In the design system, only one kind

of commodity can be purchased, in order not to have the procedure mistake,

in which the design has been more interlocking. The whole function can

simulate the transaction in kingview.
