Abstract

The invention relates to a monitoring method for abnormal behaviors of pigs and specifically relates to an intelligent monitoring method and an intelligent monitoring system for the abnormal behaviors of pigs on the basis of sound. The intelligent monitoring method comprises the stages of modeling for the abnormal sound of pig groups or pigs and analyzing and diagnosing the abnormal sound of the pig groups or pigs. The intelligent monitoring system comprises a sound sensor, a diagnosis front-end device, a network communication module and a monitoring device which are mounted in a pigsty. According to the intelligent monitoring method and the intelligent monitoring system for the abnormal behaviors of pigs on the basis of sound, provided by the invention, the behavior state of the pigs is monitored in real time by intelligently simulating an expert breeder, real-time reference and alarming information are supplied and the breeder is reminded of intervening the abnormal behaviors of the pigs in time, so that the purpose of scientific breeding is achieved. The intelligent monitoring system is simple in structure, reasonable in method, low in cost, high in stability and capable of being integrally used in large scale.

Description

technical field [0001] The invention relates to a method for monitoring abnormal behavior of pigs, in particular to a sound-based intelligent monitoring method for abnormal behavior of pigs and an intelligent monitoring system. Background technique [0002] At present, pork occupies a pivotal position in meat products, and my country is the country with the largest consumption of pork in the world. my country's pig breeding production accounts for about 50% of the world's total output, accounting for about half of the country's total animal husbandry output. Although my country is a big country in pork production and consumption, there is still a big gap in production management compared with advanced countries in the world. my country's pig industry is developing from extensive free-range breeding to medium-scale centralized breeding. In addition to providing a good breeding environment for the group of pigs, centralized breeding must also obtain and analyze the behavior o...
