嵌入式工控网络的Proteus仿真研究

Research on Proteus Simulation for Embedded Industrial Control Network

以Proteus为平台,对同一窗口放置多个单片机构成多个子站(下位机)进行了研究。采用COMPIM组件,结合物理串口或虚拟串口,应用VB6.0、C51分别编写上位机程序、下位机程序,实现子站(下位机)与主站(上位机)的通信,构成嵌入式工控网络。若采用虚拟串口,可在一台PC上实现嵌入式工控网络的仿真研究。设计结果满足嵌入式工控网络的应用要求。

With Proteus as the platform,the scheme of placing multiple single chip computers in the same window to constitute a plurality of sub-stations（ lower computers） is researched. By using COMPIM components and combining physical serial port or virtual serial port,and VB6. 0,C51 for respectively writing program of host computer and lower computer program,the communication between substation（ lower computer） and master station（ host computer）,and the embedded industrial control network is constituted. If virtual serial ports are used,the simulation research of embedded industrial control network can be implemented on one PC. The design result meets the application requirement of embedded industrial control network.
