Detection method for abnormality of fixing screws of equipment and related products

Abstract

The embodiment of the present application provides a detection method and related products for the abnormality of the fixing screws of the equipment. The motion amplification algorithm processes the shooting video to obtain the enlarged video, extracts the vibration data of multiple test points for fixing screws from the enlarged video, and determines at least one target whose vibration data does not meet the preset conditions in multiple test points according to the vibration data Test points, at least one target test point is marked as an abnormal test point, and the target video area corresponding to at least one target test point in the enlarged video is displayed, so that the vibration data can be extracted through the shooting video of the fixing screw, and according to the vibration data Determine the test point where the vibration is abnormal near the fixing screw, so that the abnormality of the fixing screw of the equipment can be detected more accurately.

Description

technical field [0001] The present application relates to the technical field of vibration detection, in particular to a method for detecting abnormality of fixing screws of equipment and related products. Background technique [0002] All mechanical and motion systems generate a variety of vibrations, some of which reflect the normal state of motion of the system, while others reflect abnormal motion of the system (internal faults, unbalanced shaft connections, etc.). Therefore, vibration detection is an important part of predictive maintenance of system equipment. For example, when the equipment is running, if the fixing screws on the equipment are abnormal, the equipment may be unstable. The vibration of the equipment is detected to provide a reference for the maintenance of the equipment. [0003] At present, vibration detection mostly adopts accelerometer equipment. Although accurate and reliable, accelerometers require long preparation and installation times, require...

AI Technical Summary

Problems solved by technology

Although accurate and reliable, accelerometers require long preparation and installation times, require physical contact with the system under test (thus changing the vibration response of the system under test), and can only test a very limited number of discrete points, so , in order to better maintain the equipment, it is necessary to conduct more accurate and reliable detection of the vibration of the equipment caused by abnormal screws
