Problems solved by technology

[0003] At present, wireless sensor network technology has been widely used in the field of agricultural production, but automation equipment in the facility breeding industry is rare
At present, the breeding industry's judgment on the delivery time of sows mainly relies on the visual observation of the breeder, which is not only heavy work but also easily affected by the subjective experience of the breeder, so that welfare breeding in facilities has not yet shown huge practical benefits

Abstract

The invention relates to a system and method for monitoring pre-natal behaviors of a sow. The system comprises a frame body, supersonic ranging nodes and a remote-control central processor, wherein the supersonic ranging nodes are mounted at the top of the frame body and are used for measuring distances from the head, back and tail of the sow to the top of the frame body, and signal output terminals of the supersonic ranging nodes are in wireless connection with the remote-control central processor and are used for sending monitoring data. According to the system and the method, through recognizing behaviors of the sow, including nesting, standing and lying, decisions can be made according to the behaviors of the sow, and warning signals are sent to mobile phones of feeders in case of abnormal conditions.

Description

technical field [0001] The invention relates to the research fields of sow welfare breeding, wireless transmission and sensor technology, and specifically relates to the research of a sow prenatal behavior monitoring system based on ultrasonic distance measurement. Background technique [0002] With the increasing scale and intensification of the modern breeding industry, automatic pig raising will become the development trend of the pig raising industry. As one of the key links in the pig raising production process, sow farrowing can accurately and real-time monitor the sow Pig prepartum behavior is of great significance in judging the time of sow farrowing. Behavior is the body language of animals, through which the adaptability and survival conditions of animals can be understood. Therefore, behavioral performance is the most direct evidence for evaluating animal welfare conditions. Real-time monitoring of sow behavior signs, timely understanding and analysis of sow beha...
