Problems solved by technology

However, the labor cost of manual inspection is too high, and the detection results are limited by the individual level of manual labor, making it difficult to obtain stable detection results
However, it is impossible to detect bridges manually in real time, and it is impossible to predict the risk of bridge cracks. Increasing the frequency of inspections may be able to detect bridge crack risks in time, but the detection cost will further increase

Abstract

The invention provides a bridge stress early estimation method, which comprises the following steps of: determining a plurality of effective grids on the lower surface of a bridge, and arranging a stress sensor on each effective grid to form a sensor matrix corresponding to the effective grid; for any effective grid, executing the following steps: acquiring stress data acquired by a sensor matrixcorresponding to the effective grid, wherein each piece of stress data comprises the position of a sensor for collecting the stress data; transmitting the stress data to an estimation model corresponding to the effective grid; and obtaining a stress estimation result output by the estimation model, wherein the stress estimation result is used for prompting the estimated stress at the position of the sensor of the stress data. According to the invention, the labor cost is remarkably saved.

Description

technical field [0001] The invention relates to the field of bridge detection, in particular to a bridge stress prediction method in advance. Background technique [0002] Routine periodic inspections of bridge inspections include bridge deck system inspections, superstructure inspections and substructure inspections. The usual method is manual inspection. However, the labor cost of manual inspection is too high, and the detection results are limited by the individual level of manual labor, making it difficult to obtain stable detection results. However, it is impossible to detect bridges manually in real time, and it is impossible to predict the risk of bridge cracks. Increasing the inspection frequency may be able to detect bridge crack risks in time, but the detection cost will further increase. Contents of the invention [0003] In order to solve the above technical problems, the present invention proposes a bridge stress prediction method in advance. The present in...
