摘要
研究了航天测控网资源集中管理、统一分配的工作模式,以及满足多星测控任务的测控网资源调度方法。提出了测控网均衡调度的方法。首先面向任务,将卫星测控任务按优先级划分,按最优分配的原则进行分配,使测控网能够支持的任务数量大;在此基础上,考虑测控站负荷和备份再进行优化,使测控网内各测控站的负荷均衡。相比其他方法,考虑了任务执行的成功概率,各测控站任务分配更均匀,便于测控网的管理。
The central management and unified allocation mode applied to the space TT＆C （telemetry, tracking and command） network, as well as the scheduling algorithms to meet multisatellite TT＆C missions are analyzed in the paper. A balanced scheduling algorithm is presented. Firstly, satellite TT＆C missions are divided into different priorities and the TT＆C stations are allocated according to the mission-oriented principal of optimization in order to support the maximum of missions as possible. Based on this result, re-optimization should be implemented to balance the workload of each station considering the workload and backup of TT＆C stations. The presented scheduling algorithm takes account of success probability of satellite TT＆C missions and makes the designated workload of each station more balanced than other algorithms. It is convenient for managing space TT＆C network.
