Problems solved by technology

At present, the acquisition of health information of broilers is mainly achieved through the continuous observation of the breeder, which wastes a lot of labor costs, and the judgment is highly subjective, and it is easy to fail to find out in time due to the negligence of the breeder Handling of sick broilers occurs

Embodiment Construction

[0065] The present invention will be further described below in conjunction with embodiment, but protection scope of the present invention is not limited to this:

[0066] combine Figure 1-Figure 2 , The patented system includes: a sound collection room 1, a sound pickup (ie, a sound collection node), an audio storage unit 2 and a PC upper computer 3. When the broiler is in the sound collection room 1, the pickup will obtain the vocalization information of the broiler and store it in the audio storage unit 2; the audio storage unit 2 saves the sound data collected by the pickup every 1 minute; and the monitoring system in the PC host computer 3 every A certain time interval (1min) will automatically read the data in the audio storage unit 2 for identification. After A / D conversion, preprocessing (filtering, windowing, and endpoint detection), feature extraction, matching identification, output identification result. When the system recognizes the cough and reaches the warni...

Abstract

The invention discloses a broiler cough monitoring method based on audio technology. A pickup located in a sound collecting room collects the vocal information in real time and transmits the information to an audio storage unit for storage through a data line. The PC reads the audio data from the storage unit at regular intervals and preprocesses the read audio data. By artificially selecting thetime period of the chicken cough state in the audio frequency, the broiler cough sound data in the time period is extracted. And the decision model is trained by SVM classifier. When the broiler voiceis recognized as cough after model classification and reaches the warning value set by the program, the PC will issue an abnormal warning to the broiler. The invention realizes automatic identification and alarm of respiratory diseases of broiler chickens through analyzing cough sound of broiler chickens, provides an automatic judgment method for early detection and treatment of respiratory diseases of broiler chickens, and realizes automatic breeding of broiler chickens in a real sense.

Description

technical field [0001] The invention relates to the technical fields of livestock and poultry breeding, audio detection, and audio recognition, in particular to a broiler cough monitoring method based on audio technology. Background technique [0002] my country's chicken production has continued to grow in the past 20 years, at a rate of 5% to 6% per year. Chicken has become the second largest meat consumer product after pork. China is also the second largest chicken producer in the world. Broiler chicken The healthy farming of the farm is directly related to food safety. [0003] With the development of intensive breeding of broiler chickens, broiler chickens have high density, poor welfare, lack of management conditions and poor house environment, and a large number of broiler chickens have been sick or even died. Respiratory disease is one of several major diseases affecting the poultry industry, and cough is its main symptom. At present, the acquisition of health infor...
