线程池在卫星地面遥测系统软件的应用

New Method of Thread Pool Using in the Satellite Remote Measurement System

卫星地面遥测系统需要确保采集到的数据完整正确,并最大限度发挥软件,相关硬件设备的潜在性能,也要确保系统正常运行,卫星地面站系统软件运行中通常要处理计算大量数据,确保接收数据正常处理和有限的计算资源配置需要系统设计人员有效地权衡,文中介绍了遥测系统软件的一般特点和普通线程池的性质,作用和它的局限性,并对一个线程池模板类作了简析,结合数据均衡提出一种改进方法应用在实际系统中,提高了系统的效率和性能。最后结合最新的技术动态提出了存在的问题和改进方法。

system measurement software generally process lots of information inputting from many devices of a satellite, it should be balanced between processing data received from these devices and running computer system limited in its resource of calculation. General characters of measurement system software and thread pool are introduced , and an analysis of template class of thread pool is given, which always works successfully in the data processing task. they also provide＇a method of thread pool modified for a real application and think of data balanee when the data processing system meet data bursting event . at last , they propose advanced method facing new environment which the system could process more data than that in current status.
