Embodiment Construction

[0048] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0049] As a front-end sound collection device for intelligent analysis based on sound, if the microphone is damaged during use and cannot be found and replaced in time, it will directly affect the analysis result of the back-end intelligent system, resulting in a decrease in the accuracy of intelligent analysis. For example, in a fact...

Abstract

The embodiment of the invention provides a microphone fault detection method and device, electronic equipment and a storage medium. The method comprises the steps of determining an audio signal collected by a to-be-detected microphone; determining a time domain analysis result of the audio signal based on the time domain characteristics of the audio signal, wherein the time domain characteristicscomprise sound intensity information and / or zero crossing point information; and / or determining a frequency domain analysis result of the audio signal based on the frequency domain characteristics ofthe audio signal, wherein the frequency domain characteristics comprise harmonic position information; and determining a fault detection result of the to-be-detected microphone based on the time domain analysis result and / or the frequency domain analysis result. The embodiment of the invention provides the method and the device, the electronic equipment and the storage medium, on-line detection ofa microphone is realized by applying the characteristics of acquired audio signals, additional detection equipment does not need to be added, the normal work of the microphone is not influenced, thelabor cost and hardware cost of microphone detection are effectively reduced, and the real-time performance of microphone detection is improved.

Description

Technical field [0001] The present invention relates to the technical field of audio collection and processing, and in particular to a microphone fault detection method, device, electronic equipment and storage medium. Background technique [0002] As a front-end sound collection device for intelligent analysis based on sound, if the microphone is damaged during use and cannot be found and replaced in time, it will directly affect the analysis result of the back-end intelligent system, resulting in a decrease in the accuracy of intelligent analysis. [0003] Current microphone fault detection methods include oscilloscope detection, multimeter detection, etc. It is usually necessary to disassemble the fixedly installed microphone for fault detection, and it is impossible to perform real-time monitoring in the working state of the microphone, which has poor real-time performance and is time-consuming and labor-intensive. Summary of the invention [0004] The embodiments of the present...
