| 摘 要： | 为了解决高速下行的卫星遥测数据的接收和处理问题,对地面卫星遥测数据处理系统进行了研究.针对集中式卫星遥测数据处理系统无法正常接收和解析下行速率较高的遥测数据的缺点,提出了一种基于分布式处理的遥测数据处理系统的设计方案.该方案将分布式系统构架和并行计算技术相结合,把原始的单机处理过程分散到多台计算机上,同时利用多台计算机的计算能力对数据进行处理.仿真测试结果表明,该方案有效地解决了集中式数据处理系统接收高速遥测数据丢包的问题,同时也具有较高的可重用性和扩展性.

| Abstract: | To deal with the problem that high-speed telemetry data receiving and processing,the ground telemetry data processing system is researched.Aimed at the shortcoming of centralized data processing system receiving and processing high-speed telemetry data incorrectly,a design of telemetry data processing system based on distributed processing is proposed.To distribute the original data processing process onto multiple computers to utilize their combined computing power,distributed system structure is combined with parallel computing technology.Results of the simulation indicate that the design can effectively solve the problem that centralized data processing system losing data packet when it is receiving high-speed telemetry data,and it also has good reusability and expandability at the same time. |
