Problems solved by technology

[0003] At present, there are mainly the following problems or difficulties in this field: First, the annotation data required for the establishment of the state model requires not only audio data collection, accumulation, and simple processing of devices in different states, but also the recording of these devices in different time periods. Abnormal audio information in order to fully obtain the audio signal information of various abnormal states

Embodiment Construction

[0018] The following describes the present invention in detail, and the features and advantages of the present invention will become more clear and definite along with these descriptions.

[0019] The present invention is described in detail below.

[0020] The method provided by the present application is used to detect the operating state of the target device based on audio features, and the operating state includes a normal state and an abnormal state, wherein the normal state refers to an operating state in which the target device operates normally without abnormal conditions; The abnormal state refers to the operating state in which the target device cannot operate normally or some functions fail. Taking a car engine as an example, to check whether it is in a normal state needs to examine multiple indicators, such as the heat generated when the engine is running and the vibration coefficient of the engine, etc. If the results of all the inspection indicators are within th...

Abstract

The invention discloses a state detection method, device and equipment based on audio characteristics. According to the method, a state detection model is established through deep learning, and the state detection model is used for detecting whether operation field sound is the sound emitted by equipment in a normal operation mode, so that it is determined whether the operation of the working equipment is normal or not. According to the device and the equipment provided by the invention, the operation state of the equipment can be quickly judged, and a quantitative basis is provided for overhauling and safe operation of the equipment.

Description

technical field [0001] The present application belongs to the field of speech recognition, and in particular relates to a state detection method, device and equipment based on audio features. Background technique [0002] Using human speech information, it is possible to establish speech recognition systems, speaker confirmation or voiceprint recognition systems, and predict the speaker's gender, emotion, age, etc. Thanks to the convenience of data collection and the development of technology, similar speech applications, such as intelligent speech recognition, voiceprint recognition system, semantic understanding, etc., have been widely established, used and continuously improved in recent years. However, audio signals are used to predict the operating status of industrial equipment, for example, to judge whether the industrial equipment is currently in a normal operating state according to the sound emitted by the industrial equipment during operation, or to predict the po...
