Abstract
In the development of an aircraft D simulator, as to the transmission between the simulator and real devices, the analysis of the mechanism of the traditional Ethernet broadcast and multicast was carried out, and an implementation scheme of reflective memory network communication based on double interrupt technique was presented. Through simulation broadcast and multicast Ethernet in the reflective memory network, high speed communication between ring network nodes was realized. The implementation of this scheme, not only solved the serial read and write in the ring network nodes communication process, also solved the problem of real-time communication, error frame, frame dropping and data synchronization between the devices in the development of the simulator. At present, the communication method has been applied to the D simulator of an aircraft.关键词
