On June 7 , the "2023 China Water Expo and the 18th China (International) Water Affairs Summit Forum " ( " Water Expo " for short ) opened in Nanjing, Jiangsu . Based on the space-time capabilities of Beidou , Qianxun has created a variety of water conservancy digital twin solutions , which were unveiled at this water expo .
As one of the implementation paths and important symbols to promote the high-quality development of water conservancy in the new stage, the construction of water conservancy digital twin engineering has always been the focus of the industry. As an important space-time infrastructure in my country, the Beidou satellite navigation system has continuously deepened its application in the field of water conservancy digital twin construction, which has effectively improved the scientific, precise and efficient capabilities of my country's water conservancy undertakings.
Qianxun Position is oriented towards the digital twin of water conservancy and has launched five major solutions, including rainwater forecasting and dam monitoring of small and medium-sized reservoirs, Beidou/GNSS automatic deformation monitoring of water conservancy and hydropower projects, intelligent management of water environment, flood control of small and medium-sized watersheds, urban flood control and waterlogging prevention, Water conservancy digital twin geospatial data baseboard and other directions.
Five solutions empower the water conservancy industry
Qianxun Location establishes three major systems - security system, standard system, and operation system, on the overall basis including "water conservancy perception layer", "communication transmission layer", "platform support layer", "business application layer" and "application scenarios". Based on the service architecture, five solutions with wide coverage and strong applicability are launched:
1. Solutions for small and medium reservoir rainwater forecasting and dam monitoring
Based on the underlying capabilities of the national Beidou ground-based augmentation system, combined with Beidou millimeter-level perception and short-message communication capabilities, it integrates a variety of monitoring sensors to provide intensive services under a unified time-space reference, and launched rainwater forecasting, dam safety monitoring, A small and medium-sized reservoir safety monitoring solution integrating reservoir four-prediction, digital monitoring, engineering video surveillance, and safety monitoring platform.
2. Beidou/GNSS automatic deformation monitoring solution for water conservancy and hydropower projects
Taking the Beidou ground-based augmentation system as the unified space-time benchmark, we provide customers with industry-leading, patented GNSS receivers and data calculation software, helping to realize high-precision and automatic appearance deformation monitoring of water conservancy projects, reducing manpower investment and improving safety levels.
3. Water environment intelligent management solution
According to the core structure of "one cabin (cockpit), two ends (governance end and server end), and N scenarios", develop and construct intelligent water environment applications, conduct three-dimensional, efficient and intelligent inspections of the water environment, and form events The whole process of online closed-loop processing from discovery, distribution, disposal to feedback realizes the intelligent management of water environment.
4. Comprehensive solutions for flood control in small and medium-sized watersheds and urban flood control
Based on Beidou space-time intelligent technology, integrating Beidou high-precision positioning, unified space-time reference, and digital twin core products, more accurately establish a digital mapping of physical water conservancy and its affected areas, and the depth of the "four forecasts" of water conservancy business forecasting, early warning, rehearsal, and pre-plan Integrate to improve the digitalization, networking and intelligence level of flood control in small and medium watersheds and urban flood control.
5. Water conservancy digital twin geospatial data floor solution
With the goal of helping the construction of digital twin watersheds, relying on Beidou space-time intelligence technology, we will strive to create a geospatial data floor solution with unified global space-time reference, centimeter-level high precision, scene-based simulation, watershed-level 3D smooth loading, and ultra-realistic visualization.
More than 30 kinds of products help water conservancy digital twin construction
The smooth implementation of the solution is inseparable from the product service support of each link. For this reason, Qianxun Position has developed and manufactured more than 30 products in 5 categories:
If a worker wants to do a good job, he must first sharpen his tools. Qianxun's complete and powerful product matrix has greatly improved the work efficiency of water conservancy workers . In the future , Qianxun Location will continue to conduct in-depth research and development , upgrade existing products, and expand product lines to assist in the construction of water conservancy digital twins .
Experience sharing to promote industry development
For a long time, Qianxun Location has been driven by the top-level design of smart water conservancy construction and customer needs, making full use of Beidou's high-precision positioning, unified time-space reference and short message communication capabilities, based on the digital twin core product of independent research and development and cloud map integration, Cooperate with top industry partners to provide innovative solutions for water conservancy project safety monitoring, water environment management, river basin flood control, urban waterlogging prevention and other application scenarios, empower the water conservancy industry with Beidou space-time intelligent technology, and improve the "four pre-prediction" capabilities of smart water conservancy , using digital twin products and services with precise time and space capabilities, to further promote the reform of water conservancy project construction and management system.
Years of technology accumulation and water conservancy practice have given Qianxun Location a wealth of industry experience. In addition to displaying the above solutions and product services, Qianxun Location will also share its experience in the industry for many years at the "Smart Water Conservancy" sub-forum on the afternoon of June 8 - "Thoughts on the Construction of Water Conservancy Digital Twin Data Baseboards Based on Beidou Space-Time Intelligence Practice", in order to use their own experience as a reference for the participants and contribute to the development of the industry.
