The invention belongs to the technical field of deep space exploration, aims to solve the problem of data loss when the extraterrestrial celestial body detector has a landing fault, and particularly relates to a data rescue system applied to the extraterrestrial celestial body detector. The data rescue system comprises a first data wireless return module arranged in a first device, a data acquisition control module, a master control module and a second data wireless return module arranged in a second device, the first device and the second device are detachably connected; the second data wireless return module is used for backing up the process detection data stored in the first data wireless return module in real time; and the master control module performs online analysis on the landingprocess state based on the data acquired by the data acquisition control module, and judges whether the landing process state can be successfully landed or not so as to execute whether the second device is separated for data return or not. According to the system, rescue of key data in the landing process can be realized so that data reference and support are provided for subsequent engineering design.

    本发明属于深空探测技术领域,旨在解决地外天体探测器着陆故障时的数据丢失问题,具体涉及一种应用于地外天体探测器的数据拯救系统,包括设置在第一装置内的第一数据无线回传模块、数据采集控制模块、总控模块,以及设置在第二装置的第二数据无线回传模块;第一装置与第二装置可分离式连接;第二数据无线回传模块用于实时备份第一数据无线回传模块中存储的过程检测数据;总控模块基于数据采集控制模块采集的数据,对着陆过程状态进行在线分析,判断是否能成功着陆,以执行是否分离第二装置进行数据回传。通过本发明可实现着陆过程关键数据的拯救,从而为后续工程设计提供数据参考和支撑。
