航天器在轨运行段遥控作业规范化设计与实现

Design and realization of normalization on telecommand program for spacecraft in operation section

针对当前航天器长期运行段遥控作业中人工干预环节较多、自动化智能化水平较低、流程标准化较低、要素不完整、事后工作不完整等问题,在分析形成遥控作业规范化需求的基础上,对遥控作业运行流程、功能模块、异常报警处置策略进行设计与规范。将遥控作业分为遥控上行前、中、后三个阶段,在现有基础上增加启动时机合法性自动检测、状态自动判别、时间条件自动驱动、注入结果自动评估、事后安全处置、自动退出、异常情况下循环报警推送处置策略等模块,完成遥控作业编写的规范性设计。最后,选取50颗在轨卫星对规范后的遥控作业进行验证,并与已有的作业进行了量化比对,结果显示,规范化遥控作业显著提升了上行工作的安全性、可靠性和运行效率,可提高航天器在轨稳定运行性。

Aiming at the problems of many manual intervention links,low level of automation and intelligence,low standardization,incomplete elements and incomplete work after the event in the telecommand operation of the long-term spacecraft operation section,the thesis designs and standardizes the operation process,function module and abnormal alarm disposal strategy of telecommand operation based on the analysis of standardization requirements.The telecommand operation is divided into three stages:before,during and after the remote control uplink.On the existing basis,the modules such as automatic detection of start-up timing legality,automatic state discrimination,automatic driving of time conditions,automatic evaluation of injection results,post event safety disposal,automatic exit,and cyclic alarm push disposal strategy are added to complete the normative preparation of telecommand operation design.Finally,50 satellites in orbit are selected to verify the standardized telecommand operation and compared with the existing operation.The results show that the standardized telecommand operation significantly improves the safety,reliability and operation efficiency of the uplink work,and improves the stability of the spacecraft in orbit.
