Abnormal sound analyzing system

Abstract

The invention discloses an abnormal sound analyzing system. The abnormal sound analyzing system comprises a sound acquisition module, a preliminary sound processing module, an abnormal sound classifying module, a control module and an alarm module, wherein the sound acquisition module is used for acquiring sound information in a surrounding environment; the preliminary sound processing module preliminary processes the acquired sound information, and filters interfering sounds to obtain abnormal sound information; the abnormal sound classifying module classifies sounds according to the abnormalsound information received by an information receiving module, calculates probability values of various sounds, and compares the calculated probability values of the various sounds with preset thresholds to obtain comparison results; the control module is used for analyzing the comparison results and sending abnormal comparison results to the alarm module. Through recognition of specific abnormalsounds, occurrence of abnormal events is more accurately detected, so that detection results of abnormal events can be provided for users in real time, the defects of a video detection method are made up so as to take corresponding countermeasures more accurately, and the effects of suppressing and aweing illegal criminal activities are achieved.

Description

technical field [0001] The invention relates to the technical field of sound recognition, in particular to an abnormal sound analysis system. Background technique [0002] Sound is produced by the vibration of molecules in the air; natural sound is a continuous signal that transmits information with sound waves as the carrier, and changes with time. The amplitude of the sound wave indicates the strength of the sound signal, and the frequency of the sound wave reflects the pitch of the sound. , is an important part of multimedia information and an essential medium for expressing thoughts and emotions; with the development of computer technology, sound signals are obtained by synthesizing waves of different amplitudes and frequencies, and the sound signals are realized Digitizing. [0003] At present, there are relatively few security products for sound analysis on the market. Some sound analysis products, such as sound intensity alarm devices, will send out an alarm signal w...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the abnormal sound analysis system disclosed in the present invention can detect the occurrence of abnormal events more accurately by identifying specific abnormal sounds, and at the same time solve the problem of traditional sound detection technology. It is easy to be disturbed, and provides users with detection results of abnormal events in real time to make up for the shortcomings of video detection methods, so as to make corresponding countermeasures more accurately and achieve the deterrent and deterrent effect on illegal and criminal acts
