随着我国航天技术的发展,星载计算机的应用范围也越来越广泛,目前被应用在通讯、资源探测、遥感、气象等众多行业和领域。而且卫星的功能越来越强,因此对星载计算机的负载要求也越来越高,需要收集大量的数据来进行处理,包括压缩、采集、数据回传等。在这些不规则的应用当中,必须要采用负载平衡算法来计算负载,使负载更加平衡,这样才能更加有效的利用资源。笔者针对基于偏差信息的星载计算机系统负载平衡算法进行了研究,希望能为广大的相关工作者提供一些参考依据。
With the development of China’s aerospace technology, the application scope of on-board computer is also more and more widely, and is currently used in many industries and fields such as communications, resource exploration, remote sensing and weather. And the function of the satellite is getting stronger and stronger, therefore the load on the on-board computer is more and more demanding, need to collect a large amount of data to deal with, include compressing, collecting, data returning and so on. In these irregular applications, load balancing algorithms must be used to calculate the load so that the load is more balanced so that resources can be used more efficiently. The author studies the load balancing algorithm of onboard computer system based on deviation information, and hopes to provide some reference for the related workers.
