Technical Field

[0002] Winter prevention is an important task for maintaining smooth traffic on roads. The steel box girder of a bridge is a key section in this work. Due to its special structure, it is more prone to ice formation than other bridges in winter. To accurately understand the changes in bridge deck temperature and promptly spread snow-melting agents on the bridge deck, various road companies currently use manual on-site measurements. However, manual temperature measurement has problems such as parking in the emergency lane at night, long temperature measurement periods, and discontinuous temperature measurement data. At the same time, parking in the emergency lane at night in rainy and snowy weather poses a greater safety risk. Due to the long temperature measurement distance and multiple temperature measurement points, the temperature measurement data is discontinuous, and the reference value of the collected data is limited. Therefore, we propose a bridge deck low temperature monitoring and early warning device to solve this problem. Utility Model Content
