Abstract

The invention relates to an intelligent decision making technology, in particular to a classification model, and provides a sound anomaly detection method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining to-be-detected audio data; performing segmentation processing on the audio data to be detected to obtain a plurality of audio sequences; performing feature extraction processing on the plurality of audio sequences to obtain a plurality of audio feature data; classifying the plurality of pieces of audio feature data, and determining category identifiers corresponding to the plurality of pieces of audio feature data; determining target audio feature data in the multiple pieces of audio feature data according to the category identifiers corresponding to the multiple pieces of audio feature data; and outputting abnormal alarm information according to the target audio feature data. The invention also relates to a block chain technology, and the obtained abnormal alarm information can be stored in a block chain.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a sound abnormality detection method, device, computer equipment and storage medium. Background technique [0002] At present, the monitoring system is mainly based on video, and there are limitations in practical applications. For example, there are blind spots when the line of sight is blocked, and it is easily affected by factors such as light and bad weather. Abnormal events are usually accompanied by abnormal sounds. Abnormal sounds can effectively reflect the occurrence of major accidents and critical situations, and have the advantages of low complexity, easy acquisition, and no space restrictions. Sound signals carry a wealth of information, and abnormal detection based on sound signals has unique advantages in many occasions where vision, smell, and touch are not suitable. Contents of the invention [0003] The present application provides a sound abno...
