Objective In order to design an intelligent feeding Internet of Things system for lactating sows，and realize the remote monitoring of feeding status of lactating sows.Method The system transmited the custom TCP communication protocol through Netty to realize the function of data transmission and instruction reply with the terminal equipment. The design of human-computer interaction interface was carried out by using SpringBoot and Vue front-end and back-end separation architecture, including pig farm production detail interface, sow feeding information query interface and statistical data download interface.Result The test results showed that the average response time of the system was 0.33 s with 3000 connections, and the amount of data processed per unit time ranged from 750 to 1180. After the system was added into the custom business thread pool, the number of data processed per unit time increased by 250, and the processing capacity increased by 31%.Conclusion The system meets the practical application requirements of connection management and data processing for intelligent feeding equipment in nursing house.
