Fracture prediction method, device and readable storage medium of fan toothed belt

Abstract

The present application provides a fracture estimation method, a fracture estimation device, and a readable storage medium for a toothed belt of a fan, and determines the monitoring feature vector sequence of the toothed belt of the fan from the operation monitoring data of the fan to be detected; The eigenvector sequence is segmented, and the multiple monitoring eigenvector sub-sequences obtained by the segmentation are clustered to obtain a plurality of state feature clusters corresponding to the various operating states of the fan toothed belt; based on the multiple state feature clusters, the predicted Estimate the predicted fracture results of the fan toothed belt. The estimated results can be obtained accurately and efficiently, so as to know in time whether the toothed belt of the fan is broken, or whether it may break, etc., which is helpful for the troubleshooting of the toothed belt of the fan and the daily maintenance of the toothed belt of the fan. maintain.

Description

technical field [0001] The present application relates to the technical field of mechanical engineering, and in particular to a fracture prediction method of a fan toothed belt, a device thereof and a readable storage medium. Background technique [0002] As a clean and recyclable energy source, wind power has developed faster and faster in recent years. The toothed belt in the fan is the core transmission component of the fan pitch system. Once it breaks during the pitch change process, the pitch system will lose the ability to control the blades, and it is easy to cause the blades to break in an environment with high wind speed. Or a major accident in which the speed is out of control. [0003] Since it is difficult to visually find obvious signs from the monitoring data before the toothed belt breaks, at present, most of them can only perform emergency shutdown after the breakage occurs after the pitch angle is obviously abnormal, and troubleshoot the fan fault through m...
