摘    要:基于一致性检验方法和动态不确定度理论,试提出一种对多传感器系统中传感器的失效进行有效检测的系统方法.本方法由于在仅有传感器测量数据而其不确定度未知的情况下即可对传感器失效做出判定,且实时性好,故十分适用于航天、遥感等传感器性能可能存在较大变化的应用场合.

关 键 词:传感器失效  信任度函数  一致性检验  动态不确定度

Abstract:A new sensor failure detection method based on consistency check and dynamic uncertainty theory is presented. It has a good performance in sensor failure detection of multisensor system. It is suitable for the case that there is only the measurement data of sensors and the uncertainty is unknown, and it also has a good real-time performance, so it can be used in the fields where the performance of the sensor may have big change, such as space flight and remote observation etc.
Keywords:sensor failure  consistency check  confidence measurement function  dynamic uncertainty theory
