Abstract

The invention relates to an equipment running state detection method and device, a storage medium and computer equipment. On one hand, a signal matrix is obtained based on all the original signal values of the original signal sequence of the target equipment, and then the corresponding operation state is determined according to the singular value obtained by the signal matrix based on the corresponding relationship between the singular value and the operation state, so that more comprehensive equipment operation state information can be obtained; in the other hand, according to the invention,the random number is added on the basis of the original signal value, high correlation of the generated signal matrix can be prevented, so that an ill-conditioned equation set is prevented from occurring in the singular value decomposition process, it is guaranteed that the obtained singular value does not approach 0, that is, the obtained singular value has reference significance, and when the corresponding operation state is determined according to the obtained singular value, the accuracy of an operation state determination result can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a method, device, storage medium and computer equipment for detecting equipment operating status. Background technique [0002] With the development of science and technology, there are more and more types of equipment, which is of great significance to the detection of equipment operation status. [0003] In the prior art, the equipment state is usually detected based on the signals generated during the operation of the equipment. The more commonly used detection method is to extract the time domain characteristics of the signal (such as the mean value, root mean square value, peak value, kurtosis value of the time domain ,), frequency domain features (such as frequency domain mean square frequency, root mean square frequency, frequency variance) or time-frequency domain features (such as time-frequency domain wavelet packet energy), etc. to determine whe...
