基于Multisim的硬币存钱箱仿真实验设计

Design of Simulation Experiment in Coin Saving Box Based on Multisim

基于Multisim软件对硬币存钱箱电路进行设计与仿真。通过光耦合器实现硬币检测单元模块,通过触发器及基本门电路实现脉冲发生单元模块,通过计数芯片实现计数单元,最终实现了硬币检测、硬币数量和总金额的显示及复位功能。采用Multisim软件对数字电路中的各种功能电路进行设计,学生进行简单的操作即可实现电路功能及其仿真波形的可视化,并可通过修改电路参数来观察参数变化对电路的影响。

This paper designs and simulates the circuit of coin saving box based on Multisim.The design uses optical coupler as the coin detection module,uses the trigger unit and logic gate circuit as the pulse generating module,and uses the counting chip as the counting module.The design has the function of coin detection,display of coin counting and the total amount of calculation,the cir-cuit also has the function of reset.It designs various function in digital circuit by Multisim,and students can realize the function of cir-cuit and the simulation visualization by simple operation,and it also can observe the effect when parameter varying.
