Movable bridge wind temperature combined automatic monitoring system

Abstract

The invention, which relates to the bridge engineering field, discloses a mobile bridge wind temperature combined automatic monitoring system comprising a bridge monitoring subsystem, a cloud server and a client. According to the invention, joint monitoring of bridge surface meteorological parameters and bridge structure temperature is realized, data analysis and processing are carried out on the cloud server, and visual data interaction is carried out through the client; a bridge surface meteorological parameter monitoring module adopts a movable design, so that the position of a sensor for meteorological data monitoring can be adjusted at any time to monitor the whole bridge surface in a time division manner; due to the structural design of a height-adjustable lower cantilever, the sensor for meteorological data monitoring can track the height of a boundary layer on the surface of a bridge, and the position of the sensor can be adjusted in real time in a self-adaptive mode; a bridge structure temperature monitoring module adopts a distributed patch type temperature sensor design, and can detect the temperature of the bridge structure in all directions; and the client not only can perform data interaction, but also can 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 and temperature combined automatic monitoring system. Background technique [0002] In recent years, with the advancement of transportation construction, more and more kilometer-level ultra-long-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, changes in ambient temperature will generate secondary internal forces inside the bridge. In severe cases, it can lead to bridge deck cracking, bearing lifting and other diseases, and even bridge damage and destruction. Therefore, the impact of sunlight temperature even surpasses the dead load and live load, and becomes the first controlling effect, causing grea...
