The invention discloses a method for monitoring poultry physical health in real time based on data extraction. The method is characterized by comprising the following steps that firstly, an area monitoring wireless sensor network is established, characteristic data, generated within 720 hours, of health poultry and characteristic data, generated within 720 hours, of sick poultry are collected respectively, data processing is conducted according to the data extraction technology, characteristic information is extracted, and a health mode bank and a sickness mode bank of the poultry physical conditions are established; secondly, real-time monitoring is conducted on the poultry physical health, relevant poultry characteristic data are collected in real time, characteristics are extracted through data extraction, matching between the characteristics and the health mode bank and matching between the characteristics and the sickness mode bank are conducted respectively, the corresponding mode banks are updated according to matching results, and a report is sent to a controller so that corresponding measures can be taken. According to the method for monitoring the poultry physical health in real time based on data extraction, the mode that data extraction and the wireless sensor network are combined is applied, the physical conditions of the poultry are monitored in real time, and the method is suitable for medium and large breeding sites. By the adoption of the method for monitoring the poultry physical health in real time based on data extraction, timely discovery and rapid prevention and treatment of diseases can be achieved through initial judgment of the health conditions of the poultry based on the detected poultry data, and therefore economic losses caused by poultry disease spreading are reduced and even avoided.
