1553B bus is widely used in domestic and foreign avionics systems. Based on the brief introduction of 1553B bus communication, the functions of 1553B bus, such as bus data scheduling, monitoring, storage and terminal emulation, are described in detail in the flight control and semi-physical simulation platform. The target machine adopts VxWorks real-time operating system, and gives the design method of the typical module of software. This design method improves the bus data transmission efficiency and reduces the bus load rate significantly. The simulation results show that the 1553B bus scheduling software can effectively realize the predetermined function in flight control semi-physical simulation platform and has stable performance. It provides a reference for the application of 1553B bus and its application in other semi-physical simulation platforms.
