Abstract

The invention provides a bridge dynamic weighing system assisted by visual technology, which is characterized by comprising: at least one dynamic strain gauge, which is arranged at the bottom of a predetermined section of the bridge, and is used for the dynamic strain data of the bridge structure generated when the vehicle passes through the bridge. acquisition; at least one bridge traffic monitoring device, arranged above the bridge deck, used to record vehicles passing on the bridge and generate vehicle monitoring video; For calculating and processing the bridge structure dynamic strain data and the vehicle monitoring video to obtain the vehicle weight of the vehicle, the calculation processing device has: a dynamic strain processing part for processing the bridge structure dynamic strain data; a video for identifying the vehicle monitoring video a vehicle identification unit; a vehicle coordinate conversion unit for converting position information into actual position coordinates; and a vehicle weight calculation unit for calculating the vehicle weight.

Description

technical field [0001] The invention relates to the field of highway bridge safety monitoring, in particular to a bridge dynamic weighing system. Background technique [0002] Modern bridges are designed and built for traffic purposes. Therefore, obtaining traffic information such as weight, speed, quantity, type, and spatio-temporal distribution of vehicles driving on bridges is of great significance for the improvement of bridge structure design specifications, safety evaluation, and maintenance decisions. In view of this, a lot of research has been done on the identification of bridge traffic information at home and abroad, and the research focus is on bridge dynamic weighing technology. [0003] In layman's terms, the principle of bridge dynamic weighing technology is to regard the bridge equipped with the structural health monitoring system as a "scale", and then use this "scale" to weigh the weight of the vehicles on the bridge. Traditional bridge dynamic weighing sys...
