A health monitoring system for connecting bolts of a steel beam of a magnetic levitation maintenance base

Abstract

The present application relates to the technical field of intelligent operation and maintenance of maglev track, and particularly discloses a maglev maintenance base steel beam connecting bolt health monitoring system, which specifically comprises a data acquisition module, a data processing module, a failure diagnosis module and a cloud service platform. The present application sets strain gauges on bolt heads for monitoring, does not need to disassemble or damage the bolts, can monitor the stress of the bolts in service state without affecting the structural integrity, reduces the risk and cost in the monitoring process, in addition, monitors the vibration characteristics of the steel beam, indirectly obtains information about whether the bolt connection is normal, finally, adopts image recognition technology to monitor the bolt loosening in real time, the fusion of the above three technologies of direct stress, indirect representation and image monitoring, superimposed with maglev vehicle operation condition data, can provide comprehensive structural health monitoring information, which is helpful for comprehensively evaluating the overall performance and safety of the connecting bolts and real-time early warning.
