摘要
对萤火一号(YH-1)火星探测器综合电子软件自主管理设计进行了研究。给出了基于事件的工作模式转换和五层软件框架设计。基于对自主安全性需求的分析,设计了能源危机实时处理;巡航段禁止综合电子执行发射机开机指令;巡航段禁止火工品起爆指令执行;巡航段禁止无效注数执行;确保星星分离状态确认正确;确保执行对重要指令冗余设计;确保CPU板和功能板电源同组;自主判别长火影提前升温,确保平安渡过火影;对日充电满36h无条件执行平台自主信标模式等自主安全性措施,确保探测器在遇到不安全事件时能顺利识别并自主处理。
The independent management design of integrated electronic system software for YH-1 Mars probe was studied in this paper. The design of software model conversion based on the event and five layer of the software frame were given out. Based on the analysis of the self-security requirement, the real time treatment of the power crisis, the inhibiting of the integrated electronic system to actuate the command of the transmitter power-on during the cruising phase, the inhibiting of the command of the pyrotechnics fusing actuating during the cruising phase, the inhibiting of the ineffective data injection actuating during the cruising phase, the ensuring of satellite-satellite separation correct, the ensuring of important command redundancy design actuating, the ensuring of the CPU board and power board in the same group, the self-judgment of advanced temperature-up of the long Mars shadow, the ensuring of passing through the Mars shadow, the actuating of self-security measures of the platform autonomous beacon model and others without any condition for charging to the sun 36 h, the ensuring of the discrimination and autonomous treatment for the insecurity events, were designed.
