Evaluating Sensor Placement for System Health Condition Monitoring

Abstract:

In this paper, an evaluation method of sensor placement is proposed for an optimal design of health condition monitoring systems. An evaluation procedure is presented which includes failure mode and effect analysis, testability analysis, choice of evaluation indexes, and implementing evaluation. A hidden semi-Markov model is employed to evaluation the effectiveness of sensor measurement. The proposed method is applied to a case of gear box vibration monitoring, where the model is validated using the experiment data of gear box monitoring.
