振动试验仿真系统中的数据通讯实现

Data Communication in the Simulation System of Vibration Test

振动试验仿真系统是一套全数字仿真系统,由三台计算机组成,形成一个Client/Sever模式的网络体系。该文在分析了振动试验仿真系统的数据通讯要求后,设计了仿真系统数据通讯方案,采用VB的Winsock控件技术实现了客户机的数据通讯编程。采用C语言设计Winsock API网络通讯程序,在MATLAB环境下编译成M函数,直接嵌入到仿真回路中,实现了MATLAB环境下的Winsock API的无缝链接,从而解决了服务器端的数据通讯问题。

The entirely digital simulation system of vibration test is a client/sever network,which is constructed by three computers. Accoring to the communication requirement of the simulation system, the communication project is presented in this paper. The Winsock control of VB is utilized to devise the communication program in the client. The sever communication programe is devised in C language. Through compiled to m function in MATLAB environment , it can be embeded in simulation loop. So the data communication in sever is realized through the seamless link between Winsock API and MATLAB.
