在结构健康监测系统中,传感器的输出与被测变量的真实值之间存在不可接受的偏差时,传感器故障会导致误报和漏报。传感器的有效性研究是结构健康监测领域中一个较新的研究方向,对于保证被监测结构健康状态评估的准确性和可靠性具有重要意义。本文提供了一个全面的审查,目前的研究和开发活动,传感器验证方法的SHM。首先,描述了七种典型的传感器故障类型,并提供了详细的方法分类。在此基础上,综述了传感器验证的研究进展,主要集中在传感器故障的检测、隔离和重构方面。最后,总结了传感器验证的结论和未来的研究方向。
Sensor faults, which occur when sensor outputs display unacceptable deviations from the true values of measured variable, will cause false alarms and missed detections in structural health monitoring (SHM) systems. The study about sensor validation is a relatively new research direction in the SHM field and it is meaningful to guarantee the accuracy and reliability of health-condition evaluations for monitored structures. This paper provides a comprehensive review of current research and development activities in sensor validation methodology for SHM. At first, seven typical sensor fault types are described and a detailed methodology categorization is provided. Following that, the progresses on sensor validation, which mainly focusses on the detection, isolation and reconstruction of sensor faults, are reviewed based on the categorization. Finally, concluding remarks and promising research efforts about sensor validation are summarized in detail.
