The Research And Design Of The General Link Controller In Advanced Orbiting System

For adapting to the development of space technique and achieving the support of the international space organization mutually, the space station of our country is adopting AOS series standard established by the CCSDS gradually. Understanding and mastering the idea, the concept and the system of AOS deeply, researching and developing the AOS key parts, have great significance for the development of our aerospace business.In the paper, the AOS characteristics, the system constitute, the business classification and layering relations are analyzed in detail according to the AOS series standard. On this basis, the function and implementation scheme of the general link controller that is one of the key parts in the AOS system are studied deeply, and the hardware and software of verification system are designed and completed.At the hardware aspect, the ARCA's GT2000 developed board with the chip of our country independent intelligent property right is adopted as the hardware of the AOS system. At the software aspect, by using of Linux operating system, a smaller inside pit is made and cut, and is made to order built-in fasten a document system. The ether net of the develop board is been utilized to correspond with the PC machine. The controller's procedure works in develop board, and receives the data which were sent by client, deals with the data to assembling, packaging, multiplexing,filling, extract packaging, extract multiplexing, extract VCA , according to the type of the data. The client procedure works in the PC and sends out the data to the server. The controller procedure uses concurrent server model to service for several customers at the same time.The thesis comes from the item"the research of the AOS system key technique", which is the key tackling item of science and technology in Inner Mongolia. As the sub-project, the research and the realization will lay a foundation for the concrete implement of the AOS key parts and do expect preparation for the further research and the development work.
