AI Technical Summary

Technical Problem

In the prior art, the operating state of the rubber roller is monitored by analyzing the similarity between the real-time vibration image and the expected vibration image. There are limitations and it is impossible to accurately determine whether the rubber roller to be tested has an abnormal operating state, especially when the rotation speed is variable.

Method used

By obtaining the end face image of the rubber roller to be tested at different times within the preset time period, and performing the amplification process according to the preset amplification strategy, the target end face image is obtained. Then, the rubber roller to be tested in the target end face image is marked according to the preset labeling box, and a two-dimensional coordinate system is constructed to obtain the coordinate information of the labeling box. The coordinate information is sorted based on the order of the acquisition time, and it is determined whether the coordinate difference is greater than the preset threshold. If it is greater than, it is determined that the rubber roller runs abnormally.

Benefits of technology

When the conveyor does not stop, the abnormal operation state can be analyzed based on a scene with variable speed, which improves the accuracy of the operating state monitoring of the rubber roller to be tested, and can capture abnormal vibrations of the rubber roller to be tested in different directions as much as possible.

Abstract

The invention discloses a belt conveyor rubber roller running state monitoring method and system, and the method comprises the steps: constructing a two-dimensional coordinate system, importing each labeled target end face image into the two-dimensional coordinate system, obtaining the coordinate information of a labeling frame in each target end face image, and obtaining the coordinate information of the labeling frame in each target end face image; sorting the coordinate information of the labeling boxes in the target end face images based on the sequence of the acquisition moments of the end face images to obtain a coordinate information sequence; judging whether a first difference value of any two pieces of coordinate information in the first coordinate information longitudinal subsequence is greater than a first preset threshold value or not and whether a second difference value of any two pieces of coordinate information in the first coordinate information transverse subsequence is greater than the first preset threshold value or not; and judging whether a third difference value of the two pieces of coordinate information in the sliding window is greater than a second preset threshold value or not during each sliding. The abnormal vibration of the to-be-detected rubber roller in different directions can be captured as much as possible, so that the accuracy of monitoring the running state of the to-be-detected rubber roller is improved.
