Problems solved by technology

However, at present, there are no breeders and veterinarians in the pig farm to inspect at night, so respiratory diseases can only be discovered in the middle and late stages, and when large-scale infection occurs

Abstract

The invention provides a cough recognition method and system of a pig. The method comprises the following steps: step A, carrying out pretreatment on a pig cough database; step B, carrying out featureextraction on the pig cough database and establishing different reference templates based on feature parameters; step C, collecting a sound signal of a pig in a pig farm in real time; step D, carrying out pretreatment and feature extraction on the collected sound signal; and step E, carrying out template matching on a processed sound input template by means of dynamic time correction and determining a cough result. According to the invention, the cough recognition method and system have the following advantages: pig cough recognition is carried out automatically and continuously for 24 hoursa day and whether one pig coughs and is attached by a disease is determined accurately; under the circumstance that feeders and veterinarians do not stay in the pig farm all the time, monitoring and detection are completed as soon as possible, so that the pig raising efficiency is improved substantially, the manpower cost is lowered, and the automatic pig raising is realized.

Description

technical field [0001] The invention relates to the technical field of sound processing, in particular to a pig cough sound recognition method and system. Background technique [0002] With the development of modern society, people's demand for pork continues to rise, and it is very necessary to provide an intelligent, scientific and efficient pig raising system. However, the research and development and use of pig raising systems from generation to generation have presented problems one by one, such as large-scale inspection of pig disease, large-scale cleaning of pig sheds, regular replacement of pig feed, and so on. Pig cough is an important indicator reflecting the health status of pigs. When pigs suffer from respiratory inflammation, lung disease, heart disease, feed powder enters the respiratory tract or the concentration of harmful gases exceeds the standard, it will cause pigs to cough. In large farms, due to the high density of pigs, it is difficult to detect coug...
