Embodiment 1

[0032] Example 1, such as figure 1 , figure 2 As shown, a sound-based pig behavior recognition system includes sequentially connected: a pig bed body module 1, which is used for pigs to lie down when they are resting, and a place for pig monitoring. The pig bed body module consists of a base plate, a top plate, Consisting of side panels and bed curtains, the bottom panel is made of 20mm thick density board, the left, right and rear side panels are made of 12mm thick density board, the top board is made of 12mm thick hollow plastic board, the left, right and rear sides of the bottom board are provided with side panels, side panels The upper end is connected with a top plate, and the front end of the top plate is provided with a hanging curtain. The hanging curtain is preferably a PVC strip hanging curtain. The length, width and height of the pig bed body can be customized according to actual needs, and pigs can enter and exit the pig bed body through the hanging curtain. Audi...

Embodiment 2

[0033] Example 2, such as image 3 A method of collecting and analyzing the vocalization behavior of pigs shown in -6, is characterized in that, comprising:

[0034]S1: Install the microphone in the pig bed body. The microphone is installed in a position where the pigs cannot touch it. Multiple microphones can be installed to ensure that the sound of pigs in all areas of the pig bed body can be collected. The microphone installation position is preferably the top plate of the pig bed body In this way, it can ensure that the sound from the pig in the pig bed body can be clearly collected, and the sound information of the pig is collected through the microphone. The microphone continuously collects the sound in the pig bed body for 24 hours. The collected audio format is wav, sampling The rate is 22050 frames per second, and the collected audio files are transmitted to the computer hardware in real time;

[0035] S2: Perform time regularization, window filtering, and frequency ...

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...
