Abstract

The invention discloses a bridge deformation intelligent detection system. The system is composed of a bridge deformation parameter acquisition platform based on a CAN bus and a bridge deformation early warning system. The bridge deformation parameter acquisition platform based on the CAN bus achieves detection and data preprocessing of bridge deformation parameters. The bridge deformation early warning system is composed of a bridge settlement detection module, a bridge heeling angle detection module, a bridge deflection detection module and an interval number fuzzy least square support vector machine bridge deformation classifier. The system effectively solves the problems that an existing bridge monitoring system does not accurately detect parameters influencing bridge deformation according to the characteristics of nonlinearity, large lag, complex bridge deformation change and the like of bridge settlement, deflection and heeling angle change, so that the accuracy and reliability of bridge deformation detection are greatly influenced.
