| 摘 要： | 在回转机械振动状态监测中通常采用二个互成９０°的测振传感器监测某一测点的振动状态，考虑到传感器布置上的这种双余度特点，运用信息论数学方法，得出了两传感器在融合过程中的冗余和互补特性；在充分利用二传感器冗余信息的基础上，提出了一种基于冗余率运算的传感器故障检测方法，试验结果良好

| Abstract: | Using the ideas of information fusion in sensor's fault recognition and taking advantage of the capabilities of sensor, the redundancy information between sensors is very attractive.For this,we propose a quantitative measure of redundancy and complementarity between various types of sensors by using information theory,and further characterize the redundancy and complementarity. Finally we give a recognition method of sensor's fault based on measurement of the redundancy. |
