Design of precision feeding monitoring system for pregnant sows based on 4G network

In order to solve the problem that the automatic feeding system of sows in large-scale pig farms at home and abroad focuses on automation but has weak information function, the author designs a set of precision feeding monitoring system for pregnant sows based on 4 G network. The system uses 4 G-DTU network transparent transmission mode for real-time data transmission, and realizes remote display of production process through PLC control technology, database technology, cloud server technology and configuration technology; at the same time, the fuzzy control algorithm based on the parameters of gestation days and fat thickness of sows is combined with the relevant knowledge base to establish control rules and achieve accurate feeding in this system. The system has been tested at pig breeding farms of Jiangxi Zhengbang Technology Co.,Ltd.. The results showed that the feeding accuracy of the system was 0.55%, at the same time, the system not only worked stably and reliably, but also had remote monitoring function, which improved the level of information management of the farm. The results indicated that the system could be widly used in animal husbandry.
