How does digital twin technology promote industrial development?

Digital double rural water supply project construction is an important content of smart water conservancy construction, and it is also an inevitable requirement to promote the high-quality development of rural water supply. The Notice of the Ministry of Water Resources and other four departments on Accelerating the Construction of Large-scale Water Supply Projects in Rural Areas requires speeding up the construction of digital double water supply system and building an intelligent application platform connected with physical engineering. "Top-level design of smart water conservancy construction" requires the construction of smart management mode of rural water supply and the realization of digital management of rural water supply projects. The "Fourteenth Five-Year Plan" national rural water supply security plan proposes to promote the construction of smart water supply system and enhance the ability of "four forecasts" (forecast, early warning, rehearsal and plan).

Taking the entity water supply project as the unit, taking the spatio-temporal data as the bottom plate, taking the mathematical model as the core, and taking the water conservancy knowledge as the driving force, digital surveying and mapping, intelligent simulation and forward-looking preview are carried out on all elements of the entity water supply project and the whole process of construction and operation, so as to realize synchronous simulation operation, virtual-real interaction and iterative optimization of the entity water supply project, and realize real-time monitoring, finding problems and optimizing scheduling of the entity water supply project.

Three-dimensional visualization technology constructs a digital twin platform including data backplane, model base, knowledge base and digital twin engine. Using three-dimensional simulation technology, the entity water supply project is digitally mapped, and intelligent simulation and simulation deduction are realized by using model platform and knowledge platform. Construction of key business intelligent applications such as comprehensive dispatching management, production operation management, water supply service management, inspection management, etc., continuous expansion and upgrading in combination with actual needs, support for mobile applications, and realize collaborative management and optimal operation of digital dual platforms and business application systems.

Combined with advanced technologies such as video fusion, BIM, 5G, Internet of Things, cloud computing, big data, etc., around the production and operation management objectives such as water quality reaching the standard, safe production, high efficiency and energy saving, three-dimensional scenes of buildings, production equipment, pipelines and other facilities in the water treatment plant area are constructed to intelligently control the real-time operation information and daily management information of the water treatment plant to ensure its scientific, efficient, safe and intelligent operation. Through the high simulation model effect of 3D, the assembly parts and disassembly of the grid machine are digitally twinned, and intelligent sensors are integrated. The 2D panel can display the running power, liquid level and status of the grid machine.

It is convenient for operators to check regularly, observe whether the liquid level difference before and after the coarse grille meets the design value, and check whether it runs normally within the set running time. Prevent large floating objects from hitting the grating bars and slag scraping equipment due to too low liquid level and too fast speed through the grating, resulting in damage to the coarse grating.

Show river branches with simplified lines, and then choose different colors to indicate the locations of pumping stations, waterworks, water treatment plants, non-drinking water, drinking water sources and water source protection areas. This design makes it easier to highlight business content and make management get twice the result with half the effort. The panels on both sides are used to display the collected real-time data statistics, and provide operational data analysis, equipment operation, water quantity management, safety management and other business support for water supply system, drainage system, water treatment system and other subsystems according to the water supply dispatching data. Form a water resources management system integrating perception, diagnosis, scheduling, early warning and correction, and create a standardized, refined and intelligent water resources operation process for users.

By reconstructing the traditional two-dimensional configuration diagram of the water plant, the main process flow of the reclaimed water plant is visually designed in 2D/2.5D, and classified according to the business units such as digestive system, flocculant system and foreign sludge receiving system, and combined with the real-time data monitored after accessing the measuring points, the operation status of the process flow and equipment is intuitively presented.

At present, new technologies such as AI, 5G, IOT, cloud computing, visualization, GIS and BIM are reconstructing the economic structure of the whole society. In the process of rebuilding business model and shaping new core competence, more and more traditional industries inherited from the old times are actively seeking digital and intelligent transformation and embracing the new era. The new generation waterworks will also develop in the direction of high efficiency, high reliability and intelligence.

Intelligent production management system of water treatment plant can achieve the goal of few people/no one and remote management, help water treatment enterprises realize advanced and efficient information management mode, reduce operating costs, improve the qualified rate of effluent and enhance their core competitiveness.

Or combined with 2.5D lightweight design, draw the monomer of each process section of the water treatment plant, and connect it with the underground pipe network system for dynamic schematic presentation, so as to facilitate users to understand the connection relationship of sludge, sewage, production and other pipelines between each process section. Rich graphic components and interface design will display boring data graphically and in scenes.

The overall design is mainly realistic style. Meet the end-to-end IT visibility of operation and maintenance personnel, clearly and quickly grasp the location and asset information of all kinds of equipment, and accurately examine the overall scene of the water plant. Real-time webpage monitors the water treatment process, statistically analyzes the water treatment data, and improves the efficiency of the water treatment process and the safety level of the factory.

The visualization section of water quality data focuses on the collaborative analysis and visual chart display of inlet water quality and outlet water quality (phosphorus, nitrogen, PH, SS, COD, residual chlorine), giving users a simple and convenient use experience. Escort the waterworks to achieve the goal of stable water quality, energy saving and consumption reduction.

According to the needs of water management in various places, intelligent sensors are equipped to collect the information of street water supply and water consumption in recent four years in real time, and remotely monitor the instantaneous and cumulative flow of water in and out, so as to control the production dynamics clearly and purposefully, and further improve the production management level.

The data can be displayed intuitively, and the alarm can be given immediately and accurately when abnormal conditions occur. The management and operation personnel of the dispatching center make comprehensive analysis and statistics and intelligent alarm according to the alarm situation of the process section and equipment, provide support for management decision-making, realize remote control of water plant operation and improve work efficiency. Relying on Hightopo digital twin technology, three-dimensional scenes are created, data such as process devices, electrical equipment and pipe networks are displayed in real time, and a remote online processing mode of the whole business process can be found and disposed in time. Breaking the inherent shackles of the relative isolation of various systems in the traditional water plant management process, the control system, monitoring system and operation and maintenance management system are integrated into an integrated platform, which makes the intelligent operation, management and service of the water plant more systematic and complete.
