Abstract: In order to solve the problems of the precision and efficiency of the gate control under the traditional irrigation management mode, the irrigation management gate control mode based on internet of water is proposed. Its characteristics included considering interactional of the system, process tracking and real-time processing. Based on the existing theoretical framework and technical characteristics of the internet of water, five capabilities of irrigation management cloud platform were discussed, including real-time perception ability, water-information interconnection ability, process tracking ability, intelligent processing ability and integration decision ability. The architecture of total channel control irrigation management cloud platform based on the internet of water was designed. The cloud platform was based on the physical water network infrastructure tier and consisted of four tiers from bottom to top: IT Infrastructure as service, platform as service, software as service, and systems integration. The cloud platform has improved the efficiency and precision of water distribution in the production of Xiganqu in Ningxia, and has obvious control effect.
