Problems solved by technology

However, on the one hand, every time the crack is analyzed, it is necessary to measure the crack, the workload is heavy, and the detection efficiency is low
On the other hand, manual detection can only analyze the current state of the crack, and the data processing method is relatively simple

Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0026] Such as figure 1 Shown, a kind of bridge crack analysis method of the embodiment of the present invention, described method comprises the following steps:

[0027] Step 110, acquiring crack data of each crack on the bridge, and determining the time series of each crack according to the crack data.

[0028] Specifically, a time series refers to a sequence in which the values ​​of the same statistical indicator are arranged in the order of their occurrence time. In this application, for any crack on the bridge, the crack data of the crack can be obtained every calibration time. The crack data can include crack depth, crack length and crack width, etc., and can also be eigenvalues ​​representing the crack state...

Abstract

The invention relates to a bridge crack analysis method and device and a storage medium, and the method comprises the following steps of obtaining the crack data of each crack on a bridge, and determining the time sequence of each crack according to the crack data; respectively processing each time sequence to obtain a stable time sequence of each crack; respectively establishing an ARIMA model ofeach crack according to each stable time sequence; based on an ARIMA model, determining the predicted crack data of each crack at a future moment according to each crack data; and drawing a curve according to the predicted crack data, and determining the change trend of the crack. According to the technical scheme, the crack data of the crack at the current moment can be obtained according to thehistorical crack data of the crack by establishing the ARIMA model, the analysis process is simple and efficient, the development trend of the crack can be predicted, the historical crack data can befully utilized, and the scientific maintenance is facilitated.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge crack analysis method, device and storage medium. Background technique [0002] Transportation is an important industry related to a country's economy and people's livelihood. With the development of economy, bridges, as important transportation infrastructure, have been built in large numbers. During the use of the bridge, due to the erosion of the natural environment, the rolling of vehicles and man-made damage, there will be cracks in various states. These cracks will reduce the bearing capacity of the bridge if it is light, and cause the bridge to break when it is heavy. Threats to the safety of pedestrians and vehicles. [0003] At present, the crack data is mainly obtained through manual detection, and then the current state of the crack is judged by analyzing the data. However, on the one hand, it is necessary to measure the cracks every time the cracks...
