Problems solved by technology

[0003] However, most of the existing bridge monitoring sensors cannot predict the remaining life of the bridge structure based on the monitored data.
This defect causes bridge maintenance personnel to judge the data fed back by sensors based on their own relevant experience, which reduces the timeliness of bridge structure monitoring and greatly increases the workload of bridge maintenance personnel.

Abstract

The invention discloses a bridge dynamic health real-time monitoring device. The monitoring device includes a monitoring module, data processing module, a security state evaluation module, an early warning and alarm module and a simulation display module, wherein the monitoring module includes a wireless sensor network, a strain sensor assembly and a displacement sensor, the data processing module includes a collection center station, a signal conditioner and a signal transmission device, the security state evaluation module includes a microprocessor, the early warning and alarm module includes an analysis processor and an alarm, and the simulation display module includes a 3D GIS simulation platform. According to the bridge dynamic health real-time monitoring device of the invention, the sensors are applied to the bridge health monitoring filed, and therefore, real-time monitoring on the health of a bridge can be realized, and the remaining life of the structure of the bridge can be monitored according to monitoring data. The bridge dynamic health real-time monitoring device is unprecedentedly advantageous in full coverage and around-the-clock monitoring.

Description

technical field [0001] The invention relates to the field of bridge health monitoring, in particular to a bridge dynamic health real-time monitoring device. Background technique [0002] Urban bridges are an important component of urban traffic arteries, and the quality of bridge maintenance is directly related to the safety and smoothness of urban traffic. Urban buildings are becoming denser and higher, which is the trend of urban development. Due to uncontrollable disasters such as natural geology or in the process of man-made construction, bridges and buildings are prone to disasters such as fracture, displacement, and inclination. The disaster is unpredictable and will bring immeasurable loss of life and property to people. It is very important to monitor the health status of bridges and buildings. [0003] However, most of the existing bridge monitoring sensors cannot predict the remaining life of the bridge structure based on the monitored data. This defect causes b...
