Abstract: In order to further improve the operation efficiency of the intelligent irrigation system for crops in China, the irrigation monitoring information processing link was studied based on the agricultural Internet platform. With big data and SOA platform as the core architecture, the internal relationship between soil environmental parameters and irrigation system data monitoring was established to finish the layout design of monitoring information and the realization of precision irrigation operation. The irrigation test verification of the system under the Internet platform showed that the improvement of irrigation monitoring information system based on the agricultural Internet platform had significantly improved the functional operation efficiency of each irrigation module, and the information monitoring accuracy and system control accuracy had been increased to 95.56% and 94.51% respectively, and the irrigation system efficiency had been increased by 7.79% compared with that before the application of the platform. The overall improvement effect of the irrigation system under the framework of the Internet platform was obvious, which would be an important foundation for China to move towards the smart agriculture, and be important practical value for the wide promotion of the similar intelligent irrigation equipment.
