中文摘要

      由于深空探测器距离远，要求具有很强的自主健康管理能力。目前大多数深空探测器自主健康管理功能为型号特定，缺乏统一的健康管理方法及软件架构，难以实现星载自主健康管理软件的通用化。针对此问题，本文对深空探测器自主健康管理需求进行了分析，提出了一种基于包应用标准和航天器接口业务标准的自主健康管理方法，设计了分层的通用软件架构。本文对架构中与健康管理相关的在轨监视业务构件、事件报告业务构件、事件动作业务构件等三个核心构件进行了详细设计，并进一步说明了架构在原理样机中的应用验证情况。

英文摘要

      Due to the long distance of deep space probe, it is required to have a strong ability of autonomous health management. At present, most of the autonomous health management functions of deep space probes are mission specific, lacking a unified health management method and software architecture, which make it very difficult to realize the generalization of onboard autonomous health management software. To solve this problem, this paper analyzes the requirements of autonomous health management for deep space probe, and proposes an autonomous health management method based on packet utilization standard and spacecraft onboard interface service standard, designs a layered general software architecture. In this paper, the design of three core components related to health management, including onboard monitoring service component, event report service component and event action service component, is described in detail, and the application and verification of the framework in the prototype is further described.
