Abstract:
The data acquisition software of FY3 meteorological satellite is an import part of the FY3 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 faulttolerant design on the basis of data recognition, classification, and processing. The implementation of the faulttolerance 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.
