Embodiment Construction

[0088] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0089] combine figure 1 , broiler feed intake detection system of the present invention, it comprises sound collecting room, switchboard, upper computer, server, wherein:

[0090] The sound collection room is used to collect audio data of broiler pecking;

[0091] The switch is used to transmit and store broiler pecking audio data;

[0092] The host computer connects to the server and reads the audio data regularly;

[0093] The single-category support vector machine OC-SVM running in the server executes the broiler pecking sound classification and recognition model algorithm, divides the sound into pecking sound and non-pecking sound, and accurately distinguishes pecking and non-pecking sounds according to the power spectral density as the sound recognition feature. Non-pecking; obtain the feed intake of broile...

Abstract

The invention discloses a broiler feed intake detection system based on an audio technology. The system comprises a sound collection chamber, a switch, an upper computer and a server, and is characterized in that the sound collection chamber is used for collecting broiler pecking audio data; the switch is used for transmitting broiler pecking audio data; the upper computer is connected with the server and reads the audio data at regular time; a broiler pecking sound classification and recognition model algorithm based on a one-class support vector machine OC-SVM operated in a server makes thesound divided into pecking sound and non-pecking sound, and pecking and non-pecking are accurately judged by taking power spectral density as sound recognition features; and the broiler feed intake isobtained based on the relationship between the broiler pecking times and the feed intake. According to the method, an audio detection technology is taken as a carrier, the relationship between pecking times and feed intake is analyzed and determined according to the pecking times of the broiler chickens during feeding, and the feed intake of the broiler chickens is calculated by utilizing high correlation between the pecking times and the feed intake.

Description

technical field [0001] The invention relates to the technical fields of livestock and poultry breeding, audio detection and audio recognition, and power spectrum density, in particular to a broiler feed intake detection system based on audio technology. Background technique [0002] The broiler breeding industry is the main component of my country's animal husbandry and one of the pillar industries of my country's agriculture and rural economy. Therefore, monitoring the health status of broilers is particularly important. With the rapid development of broiler breeding intensification and scale, improving the health and welfare of broilers has attracted increasing attention. [0003] Among the many animal behaviors related to broiler health, feeding behavior is an important basis for judging its growth status and health status, and feed intake is an intuitive reflection of its health and growth status. Therefore, accurate acquisition of feed intake information is of great imp...
