水联网全渠道控制系统设计及应用

Design and application of total channel control system based on the Internet of water

为提高灌区水资源利用的效率和效益,实现水联网数字治水,基于水联网理论和技术体系,结合宁夏水利建设要求,调研宁夏秦汉渠管理处农场渠的渠道及设备特征和管理状况,设计、开发应用于自流灌区的水联网全渠道控制系统。系统由业务层、算法层、接口层和设备层构成,业务层包含调度控制、监控分析2条业务主线,主要实现需水计划管理、全渠道智能控制、渠道及闸门运行情况监控等功能。系统在农场渠灌溉生产中投入应用,2022年春灌完整1轮供水的运行应用表明:系统在需水计划调度、闸控指令执行、需水口目标达成耗时、流量偏差方面,通过稳定可靠性、高效便捷性验证,可保证取水口高效充分供水,帮助灌区优化水资源配送过程,实现精准灌溉,降低管理成本。

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.
