Bridge safety monitoring system

1、System Introduction

(1) Establish a stable, reliable, real-time collection, analysis, and transmission health monitoring system to provide strong technical support for the long-term safe operation and maintenance of bridges and buildings;

(2) Establish a remote control and monitoring system to timely understand the operation status of the bridge and the characteristic values and preprocessing results of each measuring point through remote networks;

(3) Establish a complete evaluation and warning system through the analysis of a large number of feature values and real-time collected data;

(4) Provide reliable data for the structural damage of bridges and buildings, and provide necessary information for bridge maintenance departments to maintain and repair bridges;

(5) Provide valuable experience for monitoring and maintenance of bridges and buildings with the same structure, and promote the development of health monitoring.

2、Monitoring content

(1) Environmental loads (wind speed and direction, environmental temperature, humidity, traffic loads, rainfall, etc.)

(2)Structural deformation (settlement, linearity, deflection, inclination, displacement, cracks, etc.)

(3) Structural strain and temperature (internal and external strain, stress, and temperature, including dynamic strain and static strain)

(4) Force monitoring (representative cable tension, pore water pressure, soil pressure, etc.)

(5) Monitoring of dynamic and vibration characteristics (bridge inherent dynamic characteristics, bridge tower impact monitoring, vibration response monitoring)
