【摘要】 针对直升机工程模拟器高度集成性和实时性需求,设计了一种直升机工程模拟器的网络通讯系统。实现了基于VxWorks的中心机的多处理机之间共享内存通信,关键节点之间反射内存通信,以及其他分节点之间以太网通信,重点研究了工程实践中多处理机、多网口、并行多任务、异构系统通信等关键问题的解决途径和方法。该异构网络通讯系统已成功应用于某直升机工程模拟器的开发。更多还原

【Abstract】 To guarantee the high integration and real-time characteristic of the helicopter flight simulator, a helicopter flight simulator network communication system was designed, and the shared-buffer communication system between multiprocessor based on VxWorks RTOS, the RFM(Reflective Memory)network communication system between critical nodes, and the Ethernet communication system between the other nodes were realized. The approaches and methods in engineering practice were researched, such as multiprocessor, multi-net-port, parallel multitask and heterogeneous network communication. This heterogeneous network has been developed on a helicopter flight simulator successfully.更多还原
