摘要
中顺大围流域数字化信息获取手段经历了水文遥测系统、远程监控系统、工程调度3大系统建设过程,水文遥测信息种类涵盖水位、雨量、流量和盐度等,信息化和自动化程度比较高,具备了较好的实时监测工程运行状态、流域内水雨情态势的手段,但与数字孪生流域和智慧流域建设要求还有相当差距。该文结合中顺大围流域特征及数字化建设现状,提出利用中山市数字孪生三维空间数据共享平台作为数字底板,在接入现有感知系统的基础上,通过业务驱动和机制驱动数据更新手段,实现数字孪生流域,借助水利模型,掌握数字流域时空变化规律,推演数字流域时空变化趋势,最终实现智慧水利“四预”(预报、预警、预演、预案)目标的中顺大围智慧流域建设途径。
The digital information acquisition means of Zhongshun Dawei watershed have experienced the construction process of hydrological telemetry system,remote monitoring system and project dispatching system.The types of hydrological telemetry information include water level,rainfall,discharge,salinity and so on.The degree of informationization and automation is relatively high,and it has a better means of real-time monitoring the operation status of the project and the situation of water and rainfall in the basin.However,there is still a considerable gap with the requirements of digital twin watershed and smart watershed construction.combined with the characteristics of Zhongshun Dawei watershed and the present situation of digital construction,this paper proposes to use Zhongshan Digital Twin 3D Spatial Data Sharing Platform as digital backplane.On the basis of access to the existing perception system,through business-driven and mechanism-driven data update means,digital twin watershed is realized,with the help of water conservancy model,master the law of temporal and spatial change of digital watershed,deduce the spatio-temporal change trend of digital watershed,and finally realize the goal offorecast,early warning,rehearsal,pre-plan of smart water conservancy.
