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。
In order to solve the problem of high-speed downlink satellite telemetry data reception and processing, the ground satellite telemetry data processing system was studied. In view of the shortcomings that the centralized satellite telemetry data processing system can not normally receive and analyze telemetry data with a high downlink rate, a design scheme of a telemetry data processing system based on distributed processing is proposed. The program will be distributed system architecture and parallel computing technology combine the original single machine distributed to multiple computers, while using multiple computers computing power to process the data. Simulation results show that this scheme can effectively solve the problem of packet loss in high-speed telemetry received by centralized data processing system, and also has high reusability and scalability.
