Abstract:

The UAV Simulation System has the characteristics of large amount of data and real-time requirements. The experimental platform is based on the hardware of a sample flight simulation system which communication is based on CAN bus. According to the characteristics of CAN bus, the mechanism of bus time scheduling and state detection is designed, which can guarantee the real-time performance of the communication, and provides a correct and effective verification platform for the simulation test. And as interfaces of traditional simulation system are fixed, it is not easy to be upgraded. The registration mechanism of interfaces is designed to improve flexibility of the system, which is easy to develop the simulation system.
