航天器在轨基线控制系统设计与实现

Design and Implementation of the State Baseline Control System for On-orbit Spacecraft

摘要:

航天器在轨状态管控是保证其在轨稳定运行的重要支撑。对设计师提出的单机工作状态、软件版本状态、运行模式状态、自主功能状态的管控需求进行研究,设计研制了航天器在轨基线控制系统,通过数据库逻辑分离、分布式部署、数据订阅发布等设计保证了系统的实时性能,实现了航天器飞行状态与基线状态的实时比对,能够帮助设计师快速发现航天器飞行状态异常；同时记录航天器在轨基线变更历史,形成航天器基线变更履历,实现航天器基线状态变更有记录、可追溯。飞行状态的实时监控是对传统遥测监视的有益补充,也为后续遥测监控系统的研制提供了新的思路和参考。

Abstract:

The on orbit state control of spacecraft is an important support to ensure its safety. In this paper, the baseline control system for on-orbit spacecraft is designed and developed around the unit state, software version, working pattern and autonomous function. By the design of database logical separation, distributed deployment, data publish/subscribe, etc. the system realizes the real-time comparison between the flight state and the baseline of on-orbit spacecraft, which can help engineers quickly find the abnormal flight state of spacecraft; at the same time, it records the baseline change of on-orbit spacecraft, forms the baseline change history of on-orbit spacecraft, and realizes the record and traceability of the baseline state change of on-orbit spacecraft. The real-time monitoring of flight state is a beneficial supplement to the traditional telemetry monitoring and provides a new reference for the development of the telemetry monitoring system.
