Bridge vibration detection method and related devices

Abstract

The embodiment of the application discloses a bridge vibration detection method and related devices, which are applied to vibration detection equipment and include a camera device. The bridge vibration detection method comprises the following steps: collecting an original video of a bridge to be detected through the camera device, processing the original video according to a preset video processing strategy to obtain a target video with a motion amplification effect, and determining reference vibration data of the bridge to be detected according to the target video, wherein the motion magnification effect refers to that the area where the bridge to be detected moves is magnified in the target video; determining an operating mode of the bridge to be detected according to the reference vibration data; obtaining a pre-stored mode of the bridge to be detected; comparing the pre-stored mode and the operating mode to determine if the vibration state of the bridge to be detected is abnormal,wherein the pre-stored mode is the mode corresponding to a designed characteristic frequency of the bridge to be detected; and if so, outputting preset information. The bridge vibration detection method and related devices are beneficial to non-contact detection of a bridge vibration state, and improve the effectiveness, convenience, and versatility of vibration detection.

Description

technical field [0001] The present application relates to the technical field of vibration measurement, in particular to a bridge vibration detection method and related devices. Background technique [0002] In recent years, with the improvement of engineering quality requirements, the demand for engineering measurement is also increasing. Especially in bridge engineering, conventional bridge vibration test methods are mostly point-based detection, such as detection with acceleration sensors, etc., which can only obtain data from limited points in the structure, and use less data as bridge status detection, evaluation, and operation. , The basis for maintenance is obviously not comprehensive. In addition, a large number of sensors need to be installed in the conventional detection method, the operation is difficult, and the synchronous acquisition of data is also difficult to achieve. The test cycle is long, and it requires a lot of manpower, material and financial resource...
