摘要
对萤火一号(YH-1)火星探测器的小型化、集中式综合电子分系统方案设计进行了研究。介绍了双CPU单总线体系结构、系统重构设计、系统小型化设计和系统抗单粒子效应设计。给出了综合电子分系统软件功能及其采用的基于软件总线的开放式结构。设计的YH-1火星探测器综合电子分系统在有效实现小型化的同时能保持较高的可靠性,具自主故障诊断和系统重构的能力。
Abstract：The design of the integrated electronic subsystem of YH-1 Mars probe with the characteristics of miniaturization and integration was studied in this paper. The design of CPU single bus system architecture, system re-composition design, system miniaturization and system SEU and SEL was introduced. The function of the system software and it＇s architecture based on the software-bus were also presented. The integrated electronic subsyslem of YH-1 Mars probe designed could realize small size effectively and also keep high reliability, which had the ability of autonomous fault diagnosis and re-composition.
