　　Abstract：In order to improve the efficiency and benefit of water resources utilization in the irrigation area and to realize digital water control through the Internet of waters, a total channel control system for gravity irrigation regions is designed and developed based on the theory and technical system of Internet of waters. The channel and equipment features and management status of Nongchang Channel of Qinhan Channel Management Office in Ningxia were investigated for the development, combined with the requirements of water conservancy construction in Ningxia. The system consists of business layer, algorithm layer, interface layer and equipment layer. The business layer mainly includes two business lines of scheduling control and monitoring & analysis, which mainly realizes the functions of water demand plan management, total channel intelligent control, channel and gate operation monitoring. The system has been put into application in Nongchang Channel. After a complete round of water supply operation in spring irrigation in 2022, the system has been verified on its stability, reliability, flexibility and efficiency in terms of water demand plan scheduling, gate control instruction execution, time-consuming to meet the water demand target, and the target flow deviation. The system can ensure efficient and sufficient water supply, which will help the irrigation management office optimize the distribution process of water resources, realize precise irrigation and reduce management costs.
