【Abstract】 This thesis is based on the background of‘The Eleventh Five-Year Plan’National Defense Advanced Research Key Project. According to micro-satellite’s demand for an onboard integrated electronic system of high-reliability, high-performance and intelligence, the general and key techniques of the integrated electronic system are studied in this thesis. A prototype of a micro-satellite’s integrated electronic system is developed.In recent years, with the development of micro-satellite in China, the development of integrated electronic system in micro-satellite is making a rapid progress. However, compared with the advanced international technology of integrated electronic system, there is still a certain gap. In this thesis, at the aspects of integration, processing capacity, reliability, rapid-response ability and intelligence, the existing domestic and abroad integrated electronic systems are compared and the necessity to research the micro-satellite’s integrated electronic system, which is of high reliability, highly modularity and high level of intelligent control, is analyzed. After that, the research content, the general objectives and key techniques of the study is proposed.In order to enhance the processing capacity and reliability of the satellite-borne computer, a design of parallel computer based on dynamic interconnecting network is presented. In this design, the master computer and the slave computer are interconnected through a bridge. Based on that, the bus topological structure of dual-channel dynamic interconnecting network is studied. The checkpoint-based data storage technology and the fault diagnosis and recovery mechanism are accomplished. Therefore, the resource utilization, parallel degree and reliability of satellite-borne parallel computer system are improved.To meet the micro-satellite’s need for modular design and fast-response to space mission, a modular design of integrated electronic system based on plug-and-play technology is presented in this paper. In this design, the research content and research objectives of the integrated electronic plug-and-play system are discussed. An integrated electronic plug-and-play platform and a plug-and-play subsystem with subsystem electronic data sheet at the core are accomplished. On this basis an integrated electronic plug-and-play communication protocol applied in micro-satellite is completed.To meet micro-satellite’s need for intelligent control, the smart control program of micro-satellite’s satellite housekeeping management software is researched. Following the three-tier hierarchical control model, which are the organization level, the coordination level and the execution level, the housekeeping management smart software platform in micro-satellite of a typical configuration is designed. According to the parallel processing characteristics of satellite-borne parallel computer, the parallel program of satellite housekeeping management software platform is studied.Finally, an experimental system of micro-satellite’s integrated electronic system is designed. On the basis of the experimental system, the test of parallel performance, fault diagnosis, recovery ability and plug-and-play experiment are performed, as well as basic performance. The general and key technologies of integrated electronic system are verified.更多还原
