Research on A320 Flight Simulator Hardware Simulation Based on CAN Bus

As the wiring complexity and interference caused by too many system modules,frequent communication and complex structure while the hardware simulation of flight simulator is performing,a scheme of flight deck simulation is proposed.The host computer deals with the logical operation and simulates the function.The slave computers collect the operation information.They are networked by CAN bus to realize the flight deck function simulation.The general structure of the system is described,and data transmission protocol of the flight deck is designed.Combined with the actual application,the hardware structure of data transceiver module and software realization method of data transmission in node are given.Test results indicate that the data transmission is stable and reliable,and has achieved the expected purpose.This scheme is applied to the flight deck hardware simulation of other types of aircrafts.
