摘　　要：介绍了FY-2卫星探测数据的流通过程及接收处理.首先在FY-2卫星及探测器系统中,环境探测数据被收集、调制并发射,再由地基数据接收及解调系统将数据信号放大、解调还原并发送,最后由数据处理及警报系统将数据接收处理、保存显示,并对太阳质子事件、X耀斑进行自动电话报警.该系统是保障航天器安全和提高抗辐照水平的重要手段.FY-2 satellite is a geosynchronous meteorological satellite which is produced and lunched by China. The satellite carries the spatial particle detector and the solar X-ray detector used for detection of solar proton-event in high energy particle environment. The whole data receiving and alerting system of FY-2 consists of three systems: the earth-based system of data receiving and demodulating, the system of data processing and alerting. At first, environment detection data are collected, modulated and transmitted in the onboard system of FY-2 and detectors. Then data signals are magnified, demodulated and sent into the earth-based system of data receiving and demodulating. At last, data is received, processed, stored, displayed and judged to make alarm automatically by telephone for solar proton-events and X-ray flare in the system of data processing and alerting. It is an important way for guaranteeing space vehicle's safety and enhancing antiradiation's level.
