Abstract: Aiming at the problems existing in the bus data simulation system of airborne equipment based on 51single chip microcomputer，a bus data simulation system based on PC104 embedded system is proposed and designed.The system uses ZHHK429-PC104-Plus board and self-developed ARINC407 interface card，combined with 10-inch industrial touch color display screen，to improve the design of the original system，the development of graphical software is finished based on the Windows Embedded XP operating system combined with LabVIEW，inertial navigation and atmospheric machine data simulation output is achieved，the full state power detection of camera system can be finished in the workshop.Tests show that the system all performance indexes have been obviously improved on the basis of the original system.
