摘要
售货机器系统是根据售货需求而设计的一套自动化控制系统,整套系统由初始化、投(计)币、比较分析选择、退币和库存统计等模块构成.首先通过组态王软件绘制人机交互界面,设置相应离散变量参数,然后结合三菱FX2N系列PLC来设计整个交易过程,最后通过一个例子对所研究的售货过程各环节分别进行仿真测试,进而验证了该售货机器完全可以在规定的时限内完成系统初始化,自动售货,自动指示售罄等功能,符合自动化要求.
Vending machine system is a set of automatic control system designed according to the demand analysis.The whole system is composed of such modules as initialization,inserting (calculating) coin,comparative analysis,refunding coin,and inventory statistics.Firstly,the man-machine interface and the corresponding discrete variable parameters are drawn by Kingview software,and then the MITSUBISHI FX2N series PLC is used to design the whole transaction process.Finally,an example is carried out as a simulation test of the vending machine to verify it can complete system initialization,automatic vending,automatically indicating sold out,etc.within the prescribed time limit,which means the vending machine system meets the automation requirements.
