摘　　要：汇集软件是风云三号气象卫星计算机与网络系统的重要组成部分,在实际运行过程中发现汇集数据偶尔会掺杂异常数据,异常数据的出现不仅影响处理后0级数据的正确性,而且影响软件稳定运行,因此进行了简单实用的容错设计采用滑动检测的方式进行异常数据的判识、分类和处理,并在业务系统中加以实现。实际运行效果证明,这种容错方法能够有效的发现和判识多种数据异常,并能分类进行处理,从而显著提高了汇集软件的容错能力。The data acquisition software of FY-3 meteorological satellite is an import part of the FY-3 computer and network system,and there are occasionally abnormal data in data acquisition in operation.The abnormal data affect not only the accuracy of level 0 data but the stability of the software in operation.The data acquisition software adopts a simple and practical fault-tolerant design on the basis of data recognition,classification,and processing.The implementation of the fault-tolerance approach has been realized in the operational systems.The application practice shows that it can effectively detect and discriminate a variety of abnormal data,deal with the classification,and thereby significantly improve the software＇s capability of fault tolerance.
