| 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。

| Abstract: | 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 multi-satellite 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. |
