Bridge vibration monitoring device

Abstract

The invention discloses a bridge vibration monitoring device which comprises a plurality of position nodes and a monitoring system. Wherein the plurality of position nodes are uniformly mounted on the lower surface of the bridge, each position node is provided with a first communicator and a position sensor, and the position sensors are used for collecting position information; and the monitoring system is arranged on the outer side of the bridge, is in signal connection with the first communicators of the position nodes, and comprises a data acquisition module, a model establishment module, a model comparison module and a countermeasure output module. A large number of position sensors are evenly laid at the bottom of the bridge, position data of all point positions of the bridge are detected in real time, the position data are processed to obtain the vibration condition of the bridge, and therefore reasonable maintenance measures are taken; and meanwhile, the position and vibration characteristics of each point position of the bridge are shown by using the point cloud data, so that the three-dimensional simulation state of the bridge is obtained, and the overall bridge vibration condition of the bridge is obtained by analyzing the data.

Description

technical field [0001] The invention relates to the field of monitoring equipment, in particular to a bridge vibration monitoring device. Background technique [0002] Bridge safety is a major issue related to people's livelihood. In the monitoring of bridge safety, the monitoring of bridge vibration is an important indicator. At present, when monitoring the bridge vibration, the vibration sensor is installed on the bottom surface of the bridge to detect the bridge vibration, and the detected bridge vibration is transmitted to the central control platform in real time. Complete the alarm operation at the appropriate time. [0003] Although the bridge vibration can be detected in this way, the detected bridge vibration is local point, not the overall bridge, so the bridge vibration can not be accurately obtained if the bridge vibration occurs in other parts of the bridge. Bridge vibration analysis to obtain detailed information, thus hindering the subsequent maintenance of ...

Problems solved by technology

[0003] Although bridge vibration can be detected in this way, the detected bridge vibration is local points, not the overall bridge. In this way, bridge vibrations at other points of the bridge cannot be accurately obtained, so it is impossible to pass Bridge vibration analysis to obtain detailed information, thereby hindering subsequent maintenance of the bridge
