Platform overview
The information platform of Liulin Digital Twin Irrigation District takes the physical irrigation district as the unit, the spatiotemporal data as the base, the mathematical model as the core, and the knowledge of water conservancy as the drive. Synchronous simulation operation, virtual-real interaction, and iterative optimization of physical irrigation areas, realizing real-time monitoring of physical irrigation areas, finding problems, and optimizing scheduling service platforms, providing support for business applications such as water resource allocation, intelligent scheduling of water supply, and intelligent scheduling of flood control and drought relief in irrigation areas. Improve the ability of forecasting, early warning, rehearsal, and pre-plan (“four pre-plans”) in irrigation areas.
platform architecture
Platform Application Subsystem
The application platform subsystem includes twin cockpits in the irrigation area, water regime monitoring system, gate remote monitoring system, pumping station remote control system, meteorological and moisture monitoring system, geographic information system, video monitoring system, water bill collection management system, and inspection system And mobile APP and other main business modules.
Irrigation District Global Twin Cockpit
The global twin cockpit of the irrigation area displays in real time the direction of the canal system, the range of engineering locations, the operating status of business monitoring points, and gate control points of each business point within the jurisdiction through information collection and GIS display functions. In one graph, you can directly and interactively view the real-time status and historical trends of various monitoring points on site. It can provide water regime information, meteorological information, water diversion information, water retreat information and engineering status information required for irrigation area management at different levels in the form of pictures, text, sound, and images.
Water Monitoring System
The water regime monitoring system is mainly for the remote automatic collection and fixed-point capture of the whole process of river, reservoir, channel water regime and rain regime, and masters the dynamic change process of water level. By analyzing the monitored water and rainfall data, it provides the irrigation district management department with an auxiliary decision-making basis for evaluating the water demand and incoming water in the irrigation district, and realizes the scientific allocation of water.
Gate remote monitoring system
The gate remote monitoring system can realize the real-time display of monitoring data in one picture, and is equipped with on-site twin 3D visual real-scene pictures. Through the three-dimensional modeling of the on-site gate monitoring station, the gate main body, hoist, channel water level and other scenes are presented from multiple angles. According to the water level, the gate switch is remotely controlled, and the water level exceeds the limit, and the gate applauds for intelligent alarm. At the same time, the current opening, temperature, voltage, current flow, and cumulative flow of the gate can be checked in real time to achieve precise water control.
Pump station remote control system
The pumping station remote control system mainly realizes automatic remote control by collecting data such as water level at the inlet and outlet of the pump, operating status, and power consumption, so as to improve the efficiency of water supply and transfer in the irrigation area, and save the energy consumption of the pumping station.
Meteorological Moisture Monitoring System
The meteorological moisture monitoring system comprehensively monitors and video monitors meteorological elements such as soil moisture content, temperature and humidity, air temperature, air pressure, relative humidity, wind direction, wind speed, rainfall, illumination, etc. It provides the basis for the collection of basic information on utilization and drought relief.
Irrigation District Geographic Information System
The geographical information system of the irrigation area displays the geographical location and information of all the stations in the irrigation area through the GIS map, including all the control nodes such as all water diversion gates, flow measurement stations, water level monitoring points, and rainfall monitoring points. You can also view the current status of the gate, flow rate, opening and closing time, and video information online.
video surveillance system
The video surveillance system can understand and grasp the actual situation of each monitoring site in real time and directly. The personnel on duty at the center respond and handle accordingly according to the situation at the monitored site, so they can effectively manage the operation of water conservancy facilities and the surrounding site conditions.
Irrigation District Water Charge Collection Management System
The water fee calculation and collection management system of the irrigation district is mainly for the management of the water fee calculation and collection of the irrigation district, including functions such as comprehensive water price, execution water price, water fee query for water users, water fee advance collection for water users, water fee settlement for water users, payment query for water users, etc.
Inspection management system
Through the inspection management system, it is possible to assign the daily inspection tasks of various projects in the irrigation area, query the inspection records, manage the inspection personnel, query the inspection track, and check the problems discovered and reported by the inspection personnel during the inspection. wait.
Mobile APP management system
The mobile APP management system and the irrigation area business management platform are data interconnected. Based on real-time monitoring and data reporting, it supports the development of businesses such as real-time monitoring, water situation reporting, water volume statistics, and canal inspection. Provide a convenient channel for business development for the water release personnel and water distribution personnel of the irrigation district management unit.
