Research of Sensor Fault Identification and Warning in the Urban Bridge Cluster Monitoring System

Bridge structural health monitoring system comprises a variety of sensors for measurement of physical parameters of structure and its surrounding environment. Despite the fact that the data acquisition system is designed by the advanced sensors, the invalid data and sensor fault is unavoidable in the uninterrupted monitoring system. A novel method based on sensor correlation analysis is proposed for identifying continuous invalid data and sensor fault, which were integrated and applied in the project of main roads bridge Online Safety Monitoring Management System in Hangzhou (Phase II), a web-based urban bridge cluster monitoring system. According to a tied arch bridge case studies, the correlation degree between temperature and displacement sensor according to sliding time window is calculated. Simulation results verify the effectiveness of the designed method and the application of the method in the fault identification and warning is discussed.
