Digital Twin Hong Kong-Zhuhai-Macao Bridge: Integrated Management Information System for Greater Bay Area

Preface

A bridge connects three places, and the moat becomes a thoroughfare. The opening of the Hong Kong-Zhuhai-Macao Bridge has contributed to the accelerated economic take-off of Hong Kong, Macau and the Pearl River Delta region, driving the economic and social integration of the three places. At present, the import and export destinations via the Hong Kong-Zhuhai-Macao Bridge have covered 31 provinces (autonomous regions and municipalities) in the Mainland, and the market covers 219 countries and regions around the world. From October 2018 to September 2021, the Hong Kong-Zhuhai-Macao Bridge Customs under Gongbei Customs controlled a total of 2.408 million tons of goods with a value of 338.38 billion yuan.

The Hong Kong-Zhuhai-Macao Bridge has the characteristics of large investment scale and complex management and coordination. Its information service system needs to break through and innovate, so as to be able to exert a management level that is compatible with the scale, standard, technical difficulty and its particularity of the bridge, so as to ensure Support the main operation and management of the Hong Kong-Zhuhai-Macao Bridge.

effect display

Hightopo uses self-developed HT products to build a set of ink-and-wash 3D Hong Kong-Zhuhai-Macao Bridge-Greater Bay Area management visualization system. Through 3D modeling, combined with the rich 2D and 3D configuration of HT, the operation situation of key management objects such as bridge structure, benefit, and geographical environment can be visually displayed from multiple angles, and a complete monitoring and management system is provided around economic benefits, construction structure and other businesses. plan.

The system can adapt to different display terminals on PC and mobile terminals, helping users to control and monitor key data in the Greater Bay Area in real time, realize information exchange and data sharing, and promote the construction and development of the Greater Bay Area.

System Analysis

Full-time security management

The data monitoring of the Hong Kong-Zhuhai-Macao Greater Bay Area mainly includes the clearance height, the direction of the waterway and the clearance width of the main navigation holes. The monitoring instruments mainly include vibration sensors, differential pressure deformation measuring instruments, box-type fixed measuring instruments, three-dimensional ultrasonic anemometers, etc., which can be used to measure the wind speed, temperature, humidity, pressure, air difference and carbon dioxide, nitrogen oxides and micro-organisms in the tunnel. The parameters such as particle concentration are monitored in real time, so as to calculate and count the deflection, stress, deviation trend, temperature and humidity, etc., forming a high-precision sensing system.

Bridge dynamic environment visualization

The HT engine can support 360-degree panoramic browsing of the Hong Kong-Zhuhai-Macao Bridge. The Hong Kong-Zhuhai-Macao Bridge connects Guangdong, Hong Kong and Macao, with a total length of 55 km. It is currently the longest sea-crossing bridge in the world. It is necessary to comprehensively consider the high temperature, high humidity, high salt and windy offshore construction and operation environment of the bridge, the density of bridge positions and routes, and the requirements for water resistance. The HT 3D engine can establish 3D mathematical models of water flow and wind potential, simulate the 3D characteristics of water flow and wind movement in the Greater Bay Area, and realize virtual multi-scenario observation of key environmental trends of the bridge. In this way, the spring tide period with strong tidal power is predicted, and it provides a basis for further research on the typhoon wave process in the Greater Bay Area under extreme weather conditions.

Steel construction detail visualization

The Zhuhai Port Project of the Hong Kong-Zhuhai-Macao Bridge is a super-large transportation hub building with unique steel structure and complex building functions. Hightopo can dynamically display the design results of the bridge. Click the "Little Hand" button to view the partial structural design drawings of the bridge. It makes the management personnel more convenient and intuitive to understand the design scheme, and checks the loopholes of the design scheme through the intuitively found drawing data information.

Benefit Management

The operation and maintenance management of the Hong Kong-Zhuhai-Macao Bridge lacks a feedback mechanism and a model evaluation system. Using the HT visualization technology, the daily traffic flow and other revenue data of the bridge can be displayed through a 2D panel, thereby establishing an internal and external two-layer feedback mechanism. Managers only need to click the "Revenue" button on the left to quickly view the total benefit feedback of the Greater Bay Area operating business, including the total investment, the number of vehicles crossing the bridge on the day, and the income of bridge tolls in one screen. The right panel displays the economic driving trend through a line chart, which is convenient for operators to evaluate; the comparison of traffic flow and total revenue is displayed to help operators grasp business trends and improve operational efficiency.

monitoring network topology diagram

The topology diagram refers to the network structure diagram composed of network node devices and communication media. The quality of the network topology design has a significant impact on the performance and economy of the entire network. Through 2D and 3D configuration, HT can intuitively and clearly display the layout of monitoring network equipment in the Greater Bay Area and the paths used for data transmission. Covers the collection station-HT03, monitoring instruments (flux force cable force meter, three-way ultrasonic anemometer, GPS clock signal, inclinometer, etc.), industrial Ethernet and TCP/IP connection working methods, which are convenient for staff to see more intuitively and clearly. Clear the links between nodes and interfaces in the network to facilitate configuration and troubleshooting.

realized value

Overall planning, resource integration

Hightopo integrates data resources through visualization technology, realizes data sharing in the Greater Bay Area, and cooperates with each other for mutual benefit, forming a data application center with close cooperation and co-creation and sharing. Through visual means, it covers the construction details of the bridge and the management business of the operation process. With the operation management as the main line, through the comprehensive control and management of data associations such as benefits and basic information of the bridge, the integrated management of multi-business, multi-process and multi-information is realized.

system is fully displayed, one screen controls the whole situation

It took more than ten years for the Hong Kong-Zhuhai-Macao Bridge to be completed and opened to traffic. Under the current situation of the construction of the Guangdong-Hong Kong-Macao Greater Bay Area, the bridge will face a new opportunity for in-depth cooperation between Guangdong, Hong Kong and Macao after its opening. Hightopo comprehensively displays the Hong Kong-Zhuhai-Macao Bridge through charts, floor plans, three-dimensional graphics, etc., comprehensively and systematically aggregates and refreshes the development data resources of the Greater Bay Area, and conducts analysis and comparison to help decision makers fully grasp the development of the Greater Bay Area through one display screen. condition.

Summary

In the era of big data, data has become the "oil" of the information age. It is necessary to use problem orientation and use data analysis and mining technology to discover, analyze and solve problems, so as to increase the authenticity and objectivity of information. The data visualization system independently developed by Hightopo helps realize a data-driven industrial metaverse world, and builds an information and data service platform for interactive exchanges between governments, enterprises, and citizens.
