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.

Description

technical field [0001] The invention relates to the technical field of bridge deformation automatic detection equipment, in particular to an intelligent bridge deformation detection system. Background technique [0002] With the development of the transportation industry, bridges, as the hub of road traffic, play an increasingly important role. However, with the increase of the service life and the interference of external parameters, the bridge will be damaged to varying degrees and cause safety hazards. In order to ensure the safe operation of bridges, it is necessary to carry out regular deformation monitoring of in-service bridges, and make reasonable analysis, prediction and early warning based on long-term bridge inspection results. The present invention invents an intelligent detection system for bridge deformation according to the practical needs of bridge deformation monitoring in engineering practice. Contents of the invention [0003] The invention provides an...
