Chain topology wireless communication system for bridge intelligent health monitoring system

Abstract

A chain topology wireless communication system for bridge intelligent health monitoring system, including multiple vibration nodes, stress-strain nodes, displacement nodes and intelligent bridge nodes, multiple vibration nodes, stress-strain nodes and displacement nodes are respectively installed on the bridge span Structure, support, abutment or pier surface, monitor the vibration information, stress-strain and temperature information and displacement information of the bridge structure, and realize information transmission and interaction in a chain topology, and communicate vibration, stress-strain, temperature and displacement information to the intelligent bridge node; the intelligent bridge node wirelessly receives the information transmitted by the vibration node, stress-strain node and displacement node, realizes the information interaction, and transmits the vibration, stress-strain, temperature and displacement information to the bridge monitoring information service center . The invention realizes information interaction with intelligent bridge nodes, realizes long-term bridge displacement monitoring, and improves the robustness of the wireless communication system.

Description

Technical field [0001] The invention relates to a chain topology wireless communication system used in a bridge intelligent health monitoring system. Background technique [0002] In recent years, in the wave of nationwide urbanization, bridge construction has achieved unprecedented development. Numerous large and super large bridges and dangerous roads with unique shapes and high technological content have been built one after another, becoming an important component of highway traffic. However, the frequent bridge accidents not only cause huge social and economic losses, but also make people pay a bloody price. Experts pointed out that, in addition to design flaws, traffic overload and environmental degradation are the main factors that cause structural degradation of bridges and tunnels, and this degradation will be significantly exacerbated by high-frequency repairs and a reduction in carrying capacity. [0003] The initial detection methods for bridge health detection are rel...

AI Technical Summary

Problems solved by technology

[0003] The initial detection methods for bridge health detection are relatively backward, generally relying on naked eye observation, which is greatly affected by human factors

Later, in order to detect the internal diseases of the bridge, the drilling method was adopted. Although this method is more intuitive, the detection speed is slow, and it will inevitably damage the main structure of the bridge, thereby affecting the life of the bridge and tunnel. In addition, this method is difficult to fully reflect The overall quality of the bridge and the quality of each part
