Abstract

In response to prominent challenges commonly found in medium-sized irrigation districts in China, such as weak monitoring and sensing, insufficient metering facilities, extensive management and scheduling, isolated information systems, and inadequate operation and maintenance capabilities, and aligning with the requirements for smart water conservancy and digital twin irrigation district development, this study takes the informatization upgrading project of two medium-sized irrigation districts, Mingyang and Shangtan in Guangxin District, Shangrao City, Jiangxi Province, as a case example. Mature information technologies, including the Internet of Things (IoT), mobile communication, layered software architecture, and the data middle platform, are applied in a cross-domain manner to typical scenarios such as water volume monitoring, gate control, water resource scheduling, and water consumption measurement and billing. The technical implementation focuses on the IoT perception layer and an application support platform based on the standard computer software architecture, establishing an integrated information technology system for irrigation districts covering “perception - transmission - data - application - security - operation and maintenance.” Practical application results show that the proposed solution significantly improves water resource utilization efficiency and enhances the level of intelligent management of irrigation districts, effectively supports the comprehensive agricultural water pricing reform, and provides a technical implementation paradigm and engineering practice reference for the modernization of similar medium-sized irrigation districts.
