Sound-based pig behavior recognition method and system

Abstract

The invention particularly relates to a sound-based pig behavior recognition method and system. The system comprises a pig bed body module, an audio collection module, an audio processing and recognition module and an audio play module, wherein the pig bed body module is a place used for allowing pigs to lie at rest and monitoring the pigs; the audio collection module is used for collecting data of sound made by the pigs in a pig bed body; the audio processing and recognition module is used for collecting and saving audio data and recognizing and classifying behaviors of the pigs in audio information; the audio play module plays collected audio files; the audio processing and recognition module is composed of a signal receiving module, a storage hard disk, a loudspeaker, a time warping functional module, a window filtering functional module, a frequency domain transform functional module and a behavior prediction function module. The sound-based pig behavior recognition method and system have the advantages that a pig bed can sense the sound of the pigs and recognize the pigs' behavior types represented by the pig sound, and timely find abnormal behaviors of the pigs such as fightsand illnesses to remind management personnel to take targeted intervention measures in time, thereby improving the automatic and intelligent levels of pig raising.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding intelligent technology and equipment, and in particular relates to a sound-based pig behavior recognition method and system. Background technique [0002] The cry of pigs can generally express certain behavioral information. Pigs make different sounds when they are healthy, sick, hungry, angry, in heat, pregnant, etc. For example, when pigs have a fever, pulmonary edema, or meningitis, they make low, short, hoarse convulsions; they scream when biting their ears, tails, or fighting; they cough when they have a cold or other respiratory diseases; Makes a hungry cry when hungry. [0003] Voice recognition technology has the characteristics of fast response, non-contact and non-intrusive. If the behavior status of pigs can be detected in time through sound, various abnormal situations can be dealt with in time, and the intelligentization of pig raising can be realized. At pr...
