Embodiment Construction

[0037] The present invention will be further described below in conjunction with specific examples.

[0038] Such as figure 1 As shown, the sound-based lactating sow emotion recognition method provided in this embodiment, first, collects the audio signal in the pigpen area; then, uses wavelet decomposition and reconstruction to remove the piglet's cry and equipment sound in the audio signal , to extract the target sound of the sow; finally, the extracted target sound of the sow is used as input data to input the preset emotion recognition network model to judge the emotional state of the sow. The specific steps are as follows:

[0039] 1) Collect the audio signal in the pigsty area

[0040] In order to avoid the stress response of the wearable audio collection device to the pigs, this embodiment installs an audio collection device above the actual commercial pig house where the pigs cannot reach it, and collects audio signals from different pigpen areas. The audio signal co...

Abstract

The invention discloses a lactating sow emotion recognition method based on sound. The method comprises the steps: 1), collecting an audio signal of a pigsty region, and the audio signal comprises sowsound, piglet sound and equipment operation sound; 2) carrying out wavelet decomposition and reconstruction to remove piglet sounds and equipment sounds in the audio signals and obtain denoised sow audio data, namely sow target sounds; and 3) inputting the sow target sound as input data into a preset emotion recognition network model to judge the emotional state of the sow. The emotional state ofthe sows is sensed through the sows, negative emotions of the sows can be found in time, effective human intervention is conducted, and the health and state of the lactating sows are improved.

Description

technical field [0001] The invention relates to the technical fields of intelligent animal husbandry, audio information processing and pattern recognition, in particular to a voice-based emotion recognition method for lactating sows. Background technique [0002] Emotion is a manifestation of the physiological and psychological state of animals, and good emotions can promote the healthy growth of animals. The emotions of lactating sows are particularly important. Positive emotions can not only promote the physical health of sows, but also improve the sow’s ability to care for piglets, such as promoting milk secretion. Therefore, it is an effective way to improve the health of sows and even piglets to find abnormal lactation emotions of sows and to intervene in time. [0003] The emotions of sows are expressed through body behavior and calls. The way of observing body behavior usually needs to count the behavior of a long period of time to judge whether the emotion is positi...
