Fiber-based bridge breakage pre-warning system

Abstract

The invention discloses a fiber-based bridge breakage pre-warning system, comprising a monitoring device, a first junction warning device, a second junction warning device and an artificial monitoring station; the monitoring device is used for monitoring in real time whether a bridge body breaks or not, the first junction warning device is positioned at a junction on one side of the bridge body, the second junction warning device is positioned at a junction on the other side of the bridge body, both the first junction warning device and the second junction warning device are used for displaying breakage condition of the bridge body and preventing vehicles or pedestrians in the case of bridge breakage, and the artificial monitoring station is used for remotely monitoring conditions of the bridge body and making timely responses. The fiber-based bridge breakage pre-warning system provides intelligent monitoring and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of early warning devices, in particular to the technical field of an optical fiber-based bridge fracture early warning system. Background technique [0002] A bridge is a channel erected at both ends of a river for people to pass through. In modern society, bridges are used more widely. Because the base of the bridge is small or even non-existent, it is easy to be damaged under the action of external force, especially in some villages and towns, some rivers are narrow, and some simple bridges are generally erected to facilitate travel, and the load-bearing capacity of this type of bridge is small. , easily damaged; slightly larger bridges are relatively solid, but due to the poor management system of townships, many trucks with heavy loads also pass through the bridge body, which brings great pressure to the bridge body. When the river floods and the bridge body is damaged , due to the failure to predict th...

Problems solved by technology

Because the base of the bridge is small or even non-existent, it is easy to be damaged under the action of external force, especially in some villages and towns, some rivers are narrow, and some simple bridges are generally erected to facilitate travel, and the load-bearing capacity of this type of bridge is small. , easily damaged; slightly larger bridges are relatively solid, but due to the poor management system of townships, many trucks with heavy loads also pass through the bridge body, which brings great pressure to the bridge body. When the river floods and the bridge body is damaged , due to the failure to predict the damage of the bridge body in time, it is difficult to pass, which often brings troubles to vehicles and pedestrians, and even causes danger. This problem needs to be solved urgently
