Abstract

The embodiment of the invention discloses a signal detection method, a signal detection device, computer equipment and a storage medium. The method comprises the steps: receiving an original signal which comprises at least two sub-signals; determining the attention between the sub-signals; determining signal characteristics representing periodicity of the sub-signals according to the attention; and determining sub-signals in an abnormal state according to the signal characteristics. The attention among the sub-signals has generalization; according to the invention. The attention is not required to be paid to the signal type of the original signal and attention is only required to be paid to during feature extraction, so that anomaly detection can be performed on different types of originalsignals through attention. The generalization performance and adaptive capability of anomaly detection are improved, re-signal feature and data distribution establishment for different types of signals are not required. The workload is reduced.

Description

technical field [0001] Embodiments of the present invention relate to signal processing technologies, and in particular, to a signal detection method, device, computer equipment, and storage medium. Background technique [0002] Periodic signals are a common type of signal in daily life. In the process of signal application, such as quality assessment, preprocessing, modeling and analysis, abnormal detection is usually performed on periodic signals. [0003] By anomaly, we mean data that has a difference in the signal, and that difference is likely to be based on a difference in the generation mechanism rather than just a random deviation. [0004] At present, the anomaly detection of periodic signals is mostly detected from the aspects of signal characteristics and data distribution. [0005] However, for different types of signals, the applicable signal characteristics and established data distribution are also different, the generalization performance between different s...
