Method and system used for real time positioning and identification of abnormal sound in animal breeding shed

Abstract

The invention relates to a method and system used for real time positioning and identification of abnormal sound in animal breeding shed. The method includes acquiring real time sound data; detectingwhether animal abnormal sound is in presence according to the acquired real time sound data; when animal abnormal sound is detected, positioning the direction which the abnormal sound comes from; positioning the accurate position of a sounding animal in the direction which the abnormal sound comes from; marking the animal abnormal sound and the sounding position and storing in a history audio fileform. According to the invention, the non-intrusion, continuous and real time sound system is adopted for monitoring the abnormal sounding condition of animals at night, accurate identification of abnormal sounding of animals at night by breeding staff is assisted, and animal sound type identification accuracy and positioning precision are improved. 24-hour continuous monitoring of the animal breeding shed is realized, so that the system saves man power and material resource and improves breeding management efficiency substantially.

Description

technical field [0001] The invention relates to the field of livestock and poultry digital breeding, in particular to a method and system for real-time positioning and identification of abnormal sounds in animal houses. Background technique [0002] Sound analysis technology has become an important means to study animal behavior, animal health and animal welfare. By monitoring animal vocalizations, we can understand their own health status and individual needs, and it is also an auxiliary method for evaluating animal behavior and welfare. However, the large number of animals in large-scale chicken houses poses a huge challenge to daily feeding and management. It is difficult to achieve the requirement that breeders monitor the chicken houses 24 hours a day, and the entry and exit of personnel will bring greater stress to the chickens. In addition, chickens Unexpected abnormal conditions in the house cannot be fed back to the producer in time, which will cause immeasurable ec...

AI Technical Summary

Problems solved by technology

Although the whistle capture technology in the domestic traffic field is relatively mature, the calls of animals in livestock and poultry houses are non-short-term stable signals, and there are many sources of interference sound, which cannot be well applied to the monitoring of livestock and poultry houses. In addition, foreign Scholars' research is limited to the sound localization of larger animals such as pigs and cattle. For animal groups with a large number of individuals, such as laying hens and broilers, the efficiency and accuracy of algorithms based on TDOA technology will be greatly affected.
