摘要
Abstract
A chain breakage monitoring method based on fast Fourier transform is proposed for the scraper conveyor,ensuring the safe and reliable operation of the scraper conveyor and reducing the probability of accidents.Using the empirical mode decomposition algorithm,the chain signal of the scraper conveyor is separated from the noise.Based on the fast Fourier transform,the time-domain characteristics of vibration signals are transformed into frequency-domain characteristics,overlapping vibration signals are separated,and the vibration amplitude of the signal is determined through spectrum reconstruction.The relationship between the amplitude of the vibration signal and the threshold is determined to complete the monitoring of scraper conveyor chain breakage.The experimental results show that the proposed method can accurately monitor the working status of scraper chains under different loads,which helps to timely detect and handle faults,avoiding production interruptions and safety accidents caused by sudden fractures.关键词
