Research on data communication method in periscope semi-physical training simulation system

Data communication plays a very important role in the hardware in the loop simulation system. The system architecture of periscope semi-physical simulation system is proposed at first. Then the data communication method based on FINS between PLC and PC is introduced, the user’s interaction of scene is achieved by PLC. The communication based on TCP between 2D chart console and scene simulation system is also introduced. The 6-DOF motion model and the scene simulation system is connected by TCP, and a DR method is introduced in solving the data amount problem. The test shows that the simulation system has no error package and no missing in a simulation circle. And can meet the requirements of training, also shows good performance in reliability and real-time.
