摘　　要：针对组合导航系统的具体组成结构,提出了组合导航系统实时通讯的具体要求。在分析了VxWorks的多任务环境和中断特点后,利用TCP/IP协议支持的套接字实现了网络通讯编程,利用VxWorks提供网络函数实现了双网卡冗余备份,完成了基于VxWorks的组合导航实时通讯软件的设计。Thi paper analyses the constructive structure of integrated navigation, brings forward the principles of real time communication. On the basis of the analysis of multi - task environment and characters of interrupt, it provides the method to fulfil communication program by using the protocol of TCP/IP and realizes dual - redundance backup of network cards by using the functions of VxWorks and fulfils the design of real time communication software of integrated navigation based on VxWorks.
