Development and Realization of Display and Control System in Integrated Avionics Simulation System of Helicopter

This paper discusses the design of hardware and software of an integrated avionics simulation system based on a helicopter's bus topological structure.This paper focuses on the modularization of display,control and communication.The system simulates not only the logic of the Pilot Operation Procedure but also the communication of MIL-STD-1553 databus and ARINC429 databus in real-time.The system realizes the intercommunion of the Radar,navigation equipment,atmosphere equipment and integrated displays by emulation mode.It is showed that the system 's structure is rational and the function and the capabilties can serve for the refit requirements.
