Design of intelligent drip irrigation system for water-fertilizer integration of biogas slurry based on the Internet of Things

The key to intelligent irrigation technology depends on its water and fertilizer integration system. The current drip irrigation equipment used in water and fertilizer integration system has not been overcome the blockage problem, which is caused by biogas slurry. Therefore, this study designed a drip irrigation filter of biogas slurry anti-clogging, which aimed at the clogging problem of the existing equipment and water flow dynamics problem in drip irrigation equipment system. It established up a double guarantee to prevent the biogas slurry blockage problem, which realized the biogas slurry return to the field supporting the intelligent irrigation application and overcame the blockage challenges in drip irrigation facilities. It also used sensor technology and embedded technology to connect irrigation equipment system to the network, and the irrigation equipment system exchanged and communicated with each other through the information transmission medium, which was supplemented by internet of things to achieve intelligent identification, positioning, supervision and other functions to realize the current needs of intelligent irrigation.
