Abstract: UAV simulator is a set of ground support equipment, used to flying Cooperative training and testing of ground control device. The device achieved by simulation of electrical interface and logic relation between of UAV and ground control device, and it also can simulate the whole process of air flight of UAV. The equipment adopts the embedded computer, which uses CPCI bus structure and VxWorks operating system. It has the function of serial communication and UDP network communication, and of graphic human-machine interface.

Key words: UAV, VxWorks, Simulator, CPCI bus, Network communication
