改进的WinSock实现压气站仿真培训器内的通讯

Upgraded WinSock for the Communication in Compression Station Simulation Platform

通常大型仿真系统由多台计算机组成,各计算机完成系统的一个模块,而各计算机之间的数据是相互共享的。多台计算机间的数据通讯是一个比较普遍的问题,WindowsSocket是解决通讯的常用方法。但在该文讨论的燃气轮机——离心式压缩机组仿真培训器仿真系统中,客户端的输气管道系统是由iFix操作系统完成的,但iFix不能很好地支持Socket,因此该文结合Socket和DDE技术通过Excel中转解决了服务器到与iFix管道系统的通讯问题。而且,改进了Socket发送和接收数据函数,解决了Socket自身存在的通讯堵塞问题。

In general, large - scale simulation platforms are made up of several computers. Each computer a-chieves one function and the data of all computers are shared. Data communication between computers is a common problem in such simulation platforms. Windows Sockets is one key to it. But iFix system, a pipe system in the simulation platform, can't support Socket very well. The article shows the way of using Socket and DDE together to communicate between VC and iFix. Furthermore, the article settles the communication jam by upgrading sending and receiving functions.
