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

Abstract

The invention provides a fracture predicting method and device of a draught fan toothed belt, and a readable storage medium. A monitoring feature vector sequence of the draught fan toothed belt is determined from operation monitoring data of a to-be-detected draught fan; the monitoring feature vector sequence is segmented, clustering processing is conducted on a plurality of monitoring feature vector sub-sequences obtained by segmenting, and thus a plurality of state feature clusters corresponding to all operation states of the draught fan toothed belt are obtained; and based on the multiple state feature clusters, predicting fracture results of the draught fan toothed belt are predicted. The predicting results can be accurately and efficiently obtained, thus whether the draught fan toothed belt fractures or not, or whether the situations such as fracture possibly occurs or not is informed in time, breaking down checking of the draught fan toothed belt is facilitated, and daily maintenance of the draught fan toothed belt is facilitated.

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...
