HY-2卫星地面应用系统运行控制方案设计与实现

Design scheme and implementation for HY-2 ground segment mission control

本文介绍了海洋二号(HY-2)卫星地面应用系统运行控制方案设计与实现。运行控制子系统主要负责HY-2地面应用系统的任务调度和系统状态的监视,协调各系统之间的业务运行,是整个地面系统的神经中枢。根据系统特点采用三层C/S和B/S相结合混合体系架构。HY-2地面应用系统调度任务包括:实时调度任务、定时调度任务、数据重处理调度任务。由于数据处理流程复杂,运控子系统采用分层调度模型,这样有利于降低调度复杂性。系统采用自动运行模式:预先的业务运行计划制定、分布式的运行调度、集中式的运行状态监控。

Design scheme and implementation for HY-2 ground segment is introduced in this paper. Mission control subsystem is responsible for task scheduling,and system monitor,is nerve center of ground segment. Mixture of C/S and B/S architecture is used for operational and control system （OCS） by its characteristic.Mission control subsystem of HY-2 has three types of scheduling task：real time scheduling task,fixed time scheduling task,data reprocessing scheduling task. In order to reduce scheduling complexity,layered scheduling model is used because of complexity of data processing procedure. Automatic operation pattern is used,making plans in advance,distributed task scheduling,centralized operational system status monitor.
