摘要
针对直升机工程模拟器的实时性要求,和各个分系统仿真环境不同的实际情况,系统采用了包括共享内存、反射内存网和以太网在内的混合通讯模式来构建实时网络。文中介绍了共享内存、反射内存网和以太网这三种不同的实时网络技术,分析了它们的不同功能,同时提供了基于vxworks实时开发环境下的具体实现方法。
Considering the realtime performance of helicopter engineering simulator and the different simulation environment of the sub-system,a mixed network, which consists of Ethernet,shared-memory and reflective memory,has been built to realize real-time communication.This paper describes the technology of realtime network,including Ethernet,shared-memory and reflective memory,then analyzes their different function,and provides detailed implement method in the realtime development environment based on vxworks.
