基于Proteus的单片机多机通信的设计与仿真

针对单片机多机通信过程中异常状态多、突发性和隐藏性错误比较突出等问题,设计了由4片AT89C1单片机、指示电路、故障模拟电路等组成的多机通信电路,使用Proteus仿真软件搭建虚拟仿真平台,联合Keil软件实现软硬件协同调试,借助Proteus提供的虚拟仪器、仿真图表和探针等工具对多机通信过程进行实时分析。仿真结果表明:使用Proteus软件可对多机通信的过程进行动态分析,将抽象的通信过程直观化展现出来,有助于分析调试期间存在的问题,提高开发效率。

Facing on the problems of the SCM multicomputer communication,such as many abnormal conditions,sudden and concealment errors,a multicomputer communication is designed,which is composed of the four AT89C51、indicator circuit and fault analog circuit.a virtual simulation platform is established by Proteus,Synergetic debugging achieved in the software and hardware with Keil software,With the aid of the simulation tools such as virtual instrument、simulation charts and probes provide by Proteus,the operation of the circuit is observed and analyzed in the real time.Simulation shows that the Proteus software not only can dynamically analyze the process ofmulticomputer communication,but also can display the abstract communication process intuitively,It helps to analyze problems during commissioning and improve development efficiency.
