摘要
为满足在未来航天器上进行科学实验和空间探测的有效载荷数据采集、处理、存储、综合传输和数据管理需求 ,研制了中国第一个有效载荷数据管理系统 ;该系统在设计上采用了具有 90年代国际水平的多项先进技术 ,如采用先进的国际空间数据系统咨询委员会标准进行数据传输、以 15 5 3 B总线构成系统通信网络、大容量固态存储技术、高速多路复接器和数据管理系统软件。介绍了有效载荷数据管理系统及其技术特点 ,系统主要关键技术的设计与实现 ,以及由主要关键技术构成的缩微系统的在轨试验情况和结果。
The first Payload Data Management System( PDMS) has been developed in China to meetthe requirements of the data acquisition,processing,recording,transmission as well as data handling for the payloads of the science experiments and space exploration on the spacecraftin future. The designs of the system adoptseveral advanced technologies corresponding to international levels of the 1990 ' s such as data transmission according to the CCSDS standard,data communication network based on15 5 3 B data bus,mass solid state recorder technology,High Rate Multiplexer and management software of PDMS. PDMS and its technical characteristics,the design and implementation of the key techniques of the system are described. The onboard test results of the miniature system composed of the key techniques in the mission of satellite are also given.
