多微机仿真系统中的实时通信机制

AN REAL─TIME COMMUNICATION MECHANISM IN A MULTI─MICROCOMPUTER EMULATION SYSTEM

本文介绍作者开发的火电机厂仿真系统中实时通讯机制。首先介绍仿真系统的组成、任务划分及网络拓扑结构，然后给出采用共享内存技术实现结点内进程间通信的程序设计方法及采用客户／服务器模型实现网络通信的程序设计算法。

This paper introduces an real - time communication mechanism in a thermal powerplant emulation system by us. First, the system organization .task distribution and networktopology,then gives the programming method of shared memory for process communicatingin a node,and algorithm of client/server mode for process communicating in the network.
