Design And Implementation Of Aerial General-Purpose Telemetering-Telecontrol Terminal

This thesis is a study to solve the problems when design the telemetering-telecontrol system of UAV, about how to design a high-speed and general-purpose link terminal, and how to continue to use it in the near future. Those problems are very important study in the telecontrol-telemetry system of UAV.This project design an aerial general-purpose telemetering-telecontrol terminal based on embedded PowerPC,1553B/1394b avionics bus and FPGA re-configure technology. The terminal is powerfull to process data, generally applicable and can be configured flexibly. This terminal will cover the function performance requirements of most system consumer in the near future. In the hardware, this case complete the core circuit design based on PowerPC MPC8270and the interface cards based on1553B and1394b bus protocol. In the software, this case implement the data-swtich function of the aerial general telemetering-telecontrol terminal, which is supportted by the embedded software system of Vxworks and custom-built application programs. This thesis also design a general-purpose architecture of the aerial telemetering-telecontrol terminal, which can make generally applicable in other telemetering-telecontrol system, and discuss how to design the link equipments in the future.The result of the test:Using different modularization interface cards and configured different embedded programs, this aerial general-purpose telemetering-telecontrol terminal cover the function performance requirements of most telemetering-telecontrol system. This terminal is light weight, small physical volume, low-power and high-reliability, is adapt to the application of the UAV Platform.
