A mobile bridge wind temperature combined automatic monitoring system

Abstract

The invention discloses a mobile bridge wind temperature joint automatic monitoring system, which relates to the field of bridge engineering and includes a bridge monitoring subsystem, a cloud server and a client. The invention realizes the joint monitoring of bridge surface meteorological parameters and bridge structure temperature, performs data analysis and processing on the cloud server, and conducts visual data interaction through the client; the bridge surface meteorological parameter monitoring module adopts a movable design, which is used for meteorological The sensor for data monitoring can be adjusted at any time to monitor the entire bridge deck in a time-division manner; the height-adjustable lower cantilever structure design enables the sensor used for meteorological data monitoring to track the height of the boundary layer on the bridge surface and adjust the sensor position adaptively in real time; The bridge structure temperature monitoring module adopts the design of patch-type temperature sensors arranged in a distributed manner, which can detect the temperature of the bridge structure in all directions; the client can not only exchange data, but also store data for a long time.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a mobile bridge wind temperature joint automatic monitoring system. Background technique [0002] In recent years, with the advancement of transportation construction, more and more kilometer-scale super-span bridges are being constructed and planned. As infrastructure, bridges are exposed to the natural environment all year round, and will inevitably be affected by seasonal temperature changes, short-term strong cooling, strong solar radiation and strong winds. Due to the existence of beam end constraints, the change of ambient temperature produces secondary internal forces inside the bridge, which can lead to bridge panel cracking, lifting of supports and other diseases in severe cases, and even bridge damage. Therefore, the effect of sunlight temperature even exceeds the dead load and live load, and becomes the first control effect, which causes great harm to the durability ...
