载人月球探测飞行器综合电子系统技术发展研究

Design of Manned Lunar Spacecraft Avionics System Structure

针对载人月球探测飞行器数据种类多、数据量大、数据分布远的特点和高可靠性数据通信要求,通过调研国内外航天器综合电子系统发展趋势和系统分析载人月球探测任务的研制需求和技术特点,秉承网络一体化、计算通用化、执行集成化、软件APP化的设计理念,提出了全新的“统一管理-区域执行”两层分级控制综合电子系统架构,对高性能计算、时间触发网络、高集成采集驱动、分时分区操作系统等关键技术的研究目标和实施途径进行了详细阐述,应用于载人月球探测飞行器综合电子系统设计后,将有效提升自主健康管理和任务规划能力、功能密度、设计可靠性及有人参与的闭环控制能力。

In view of the characteristics of data in the manned lunar exploration vehicle,such as varied kinds,large amount and far distribution,and the requirements for high reliability data communication,by investigating the development trends of avionics system in spacecraft at home and abroad and systematically analyzing the needs and technical characteristics of manned lunar exploration missions,adhering to the design concept of uniform network,current compute,composite execute and software APP,a new two-layer hierarchical control integrated electronic system architecture of“unified management-regional implementation”is proposed.The research objectives and implementation approaches of key technologies such as high performance computing,time-triggered network,highly integrated acquisition and driver,time-sharing and partition operating system are described in detail.Applied to the integrated electronic system design of manned lunar exploration vehicle,it will effectively improve the capability of autonomous health management and mission planning,functional density,design reliability and closed-loop control with human participation.
