Win32API在过程实验平台开发中的应用

为方便对复杂工业过程的建模与控制研究，开发了过程实验平台。平台运行时由在Visual C 环境下编译链接的仿真服务器进程与在Visual Basic环境下编译生成的仿真操作站进程组成，仿真服务器承担计算任务，仿真操作站是数据显示与用户操作界面。仿真操作站定时从仿真服务器接收过程数据，并把用户操作实时发送到服务器。为实现不同开发环境下的进程间通讯，使用了管道函数、进程函数等Win32 API函数。该文介绍实验平台的设计思想与主要实现技术，并给出部分调用函数的具体形式。

Application of Win32 APIs in Development of Process Simulation Experimental Platform

A process experimental platform is designed and developed for complex process industrial modeling and control. This platform comprises simulation server, which is compiled and linked under Visual C++ circumstance, and simulation operating station, which is compiled under Visual Basic developing desktop. Simulation server works as a computational platform while simulation operating station is a user interface. Process data are incepted periodically by operating station from server. Also operations of users are transmitted from operating station to server. Win32 API functions, such as pipe functions and process functions, are used for complementing communication of different processes. The architecture and complement of the platform are introduced. Also part of codes and user interfaces of the platform software are given.
