Research on Digital Transformation Mode of Hydrologic Monitoring Work in Hydrometric Station

开展水文站水文监测业务数字化转型是顺应数字时代需求、推动新阶段水利高质量发展的重要路径。本文梳理了水文监测模式发展的四个阶段，分别为萌芽、形成、发展及现代化阶段，总结了传统水文监测中流量、泥沙自动监测存在“卡脖子”、监测数据存在信息孤岛和业务割据、监测产品缺乏价值等问题，以构建数字孪生汉口水文站为例，从基本概述、总体框架、关键技术及对策等方面提出了水文站水文监测数字化转型模式。该成果可为类似水文站水文监测数字化转型提供参考。The digital transformation of hydrologic monitoring work in hydrometric station is an important way to meet the needs of the digital era and to promote high-quality development of water conservancy in the new stage. This paper reviewed four stages of the development of hydrologic monitoring mode, which were germination, formation, development and modernization. The paper summarized the problems in traditional hydrologic monitoring such as “bottleneck” in automatic monitoring of discharge and sediment, information silos in monitoring data and work division, lack of value in monitoring products. Taking the digital twin in Hankou hydrometric station as an example, it puts forward the digital transformation mode of hydrologic monitoring in hydrometric station from basic overview, overall framework, key technologies and countermeasures. The results can provide reference for digital transformation mode of hydrologic monitoring in similar hydrometric station.
