The invention provides a bridge train load action time history extraction method and device and terminal equipment. The method comprises the steps: acquiring first image data corresponding to a firsttarget and second image data corresponding to a second target; determining a starting moment of the train load according to the second image data, and respectively determining a first template image of the first target and a second template image of the second target based on the starting moment of the train load; matching the first image data with the first template image, and performing binary clustering processing on a matching result to obtain a first matching sequence; matching the second image data with the second template image, and performing binary clustering processing on a matchingresult to obtain a second matching sequence; and determining the time history of the bridge train load effect based on the first matching sequence and the second matching sequence. According to the bridge train load action time history extraction method and device and the terminal equipment provided by the invention, the time history extraction cost of the train load action can be reduced, and thetime history extraction precision is improved.
Description
technical field [0001] The invention belongs to the technical field of bridge structure health monitoring, and more specifically relates to a method, device and terminal equipment for extracting time history of bridge train load action. Background technique [0002] As a large-scale structure on the traffic line, how to ensure that the bridge maintains a good health during the operation period is of great significance to ensure the safe and smooth transportation of the line. In order to ensure the safe operation of bridges and avoid serious accidents, a bridge health monitoring system that monitors the health of bridge structures has emerged as the times require. The current bridge health monitoring system includes a large number of data acquisition devices. During the service of the bridge, the data acquisition device will collect a large amount of monitoring data at all times. The bridge health monitoring system analyzes the bridge structure under the train load according ...
