Full-state multifunctional intelligent health monitoring system for bridge

Abstract

The invention relates to the technical field of bridge monitoring and detecting, in particular to a health monitoring system for judging bridge vertical frequency, torsion frequency, vibration type, damping, roughness and damages. The full-state multifunctional intelligent health monitoring system for the bridge comprises a traction car, a connecting component, a measuring car, and a signal acquiring and processing system, wherein the traction car is a power traction device of the full-state multifunctional intelligent health monitoring system for the bridge, the connecting component is used for connecting the traction car to the measuring car, a signal acquiring device is mounted in the measuring car, the measuring car moves on the detecting bridge or stops on the bridge, so that a bridgedynamic signal is picked up; and finally, signal data is processed by the signal processing device, so that a health state of the bridge is obtained. The full-state multifunctional intelligent healthmonitoring system has the characteristics of being movable, economical, high in efficiency and the like, can simply effectively pick up and process bridge dynamic response in real time to obtain moreaccurate bridge health data, so that a feasible method is provided for the bridge monitoring and detecting field.

Description

technical field [0001] The invention relates to the technical field of bridge monitoring and detection, in particular to a health monitoring system for judging the vertical frequency, torsional frequency, mode shape, damping, roughness, damage position and degree of a bridge. Background technique [0002] The traditional bridge monitoring system is a direct measurement method, which needs to install a large number of sensors on the bridge, which is expensive and has poor reusability. At the same time, the installation, disassembly, maintenance and maintenance of instruments all depend on on-site operations, and bridges must also be blocked, which is a serious disturbance to traffic services. At present, the number of bridges in our country is huge, and the traditional bridge monitoring system is neither economical nor seriously hinders the travel needs of the people. Therefore, there is an urgent need to explore and solve an economical method that does not affect the travel...
