Walk with the Olympics: Create 3D visualization of smart stadiums

祝贺中国队在东京奥运会夺得金牌 38 枚、银牌 32 枚、铜牌 18 枚。中国健儿在奥运舞台上交出了一份璀璨的成绩单。用一场场精彩绝伦的比赛，演绎“更快、更高、更强、更团结”的奥林匹克格言。

Athletes from all over the world will gather for the 2020 Tokyo Olympics to gallop and fight for national honor. The Olympic Games are held at the Tokyo National Arena. The Olympic venue can accommodate more than 60,000 spectators. Due to the epidemic, the number of visitors is controlled within 1,000.

As an infrastructure serving sports events and citizens' cultural and sports activities, the gymnasium has a large construction area, a large number of mobile personnel, and the changing scene conditions. It has high requirements for evacuation, early warning of violent incidents, and emergency plans. Use Hightopo's product HT visualization technology to link the monitoring system with other subsystems (such as alarm, lighting, sound reinforcement, etc.) to effectively ensure the safe operation of the venue. HT visualization allows the perfect integration of 3D scenes and 2D data panels.

effect display

With Qingdao Stadium as the carrier, the digital twin stadium and surrounding facilities and environment. Show the full view of the venue from far to near, lightweight design, fast loading speed. Floor management and control through smart buildings, each floor can be viewed separately, and managers can quickly view escape channels and indoor equipment.

Through HT, an interactive Web 3D scene can be realized, which can be zoomed, panned, and rotated, and each device in the scene can respond to interactive events. Combined with the powerful rendering capabilities of the HT engine, it ensures that the scene can be loaded and run efficiently and smoothly on the Web and that the scene has an excellent visualization effect. Based on three-dimensional technology, the 3D model vividly presents the outdoor and indoor security deployment and infrastructure of the venue. The building is transparent, seamless switching between indoor and outdoor.

flow perception

The crowd density in public places is getting higher and higher, group incidents are increasing day by day, and the intensive flow of people has increased the difficulty of security and service management. The 2D panel on the left can monitor the flow of people, display the density of people flow, and query the regional congestion index. Through the display of area charts and histograms, managers can discover the accumulation of passenger flow in time and quickly diversify.

Crowd density analysis uses advanced target detection, identification, tracking and other technologies to count the number and density of the crowd and other characteristic indicators, monitor the safety of the crowd in public places, and help us grasp the correct crowd density data and trend, so as to carry out reasonable security management . Managers can establish a passenger flow early warning mechanism through passenger flow monitoring to effectively guide and evacuate the passenger flow that exceeds the carrying capacity of the place.

The 2D panel on the right is the control of internal personnel, allowing managers to know the attendance of front-line personnel such as security, cleaning, and guards. By reporting the task progress, it helps managers analyze the shortcomings of daily patrols.

Check the heat map, sensor door, camera, you can view the crowded area and the distribution location of related equipment.

Three-dimensional thermal map of passenger flow

Through the image recognition and analysis of multiple cameras, a complete thermal map of the park can be formed. Shows the degree of concentration or even crowding in a certain place of the gymnasium. Red means more people and green means less people. Evacuation of people can be considered in advance.

flow of people at the entrance and exit

Check the perceiving door option, you can display the entrances and exits of the venue, click the corresponding entrance ban number, view the traffic trend of the entrance, and display information such as the peak period of the entrance and the average flow of people. Through data presentation, venue managers can efficiently and intelligently operate and maintain.

Visualization of camera layout

Click the camera option to jump to the layout of the camera equipment on each floor of the venue. The camera monitoring can carry out a full range of security monitoring and prevention for the venue, and it is convenient to call during monitoring collection.

Communication equipment visualization

The 5G base station is the core equipment of the 5G network, providing wireless coverage and realizing wireless signal transmission between the wired communication network and wireless terminals. With the continuous development of information networks, the operation and maintenance management of venues, the implementation of equipment during events, and the stability of information and communication for the staff in the venue are all inseparable from the 5G network. The information on the panel presents the base station rate, connection rate, number of 5G telecom users, telecom traffic, 5G Unicom users, mobile users and other information. The installation of 5G base stations, communication vehicles and other equipment outside the venue is not only conducive to the convenience of the museum, but also Let the network communication operation and maintenance personnel know the communication situation of the personnel during the event, the coverage rate of 5G use, and so on.

Real-time monitoring

Through the HT visualization, you can view the hazard warning, fire alarm rate, personnel gathering rate, illegal intrusion rate, etc. After accessing people flow data, the people gathering area and processing progress can be scrolled. Perception door information display, record the information of every entry, which is convenient for troubleshooting. Face capture machines can be installed at the entrances and exits of the venues to form passenger flow portraits through big data analysis, allowing managers to grasp the personnel structure. Connected to the monitoring screen in the venue, security personnel can quickly locate, realize real-time prediction, real-time discovery, and real-time disposal in case of problems.

Video Fusion

The digitization of information flow, coding and compression, and open protocols enable seamless connection between the intelligent network video surveillance system and the various subsystems in the security system, and realize management and control on a unified Tupu visual management platform.

Integrate multiple island systems to break the information barriers between systems. Combined with video fusion technology, multiple surveillance videos can be fused, so that the originally fragmented video can be viewed in a panoramic view of the real three-dimensional scene, and the overall scene can be grasped from any angle required to help users quickly overview the overall situation. The three-dimensional scene and the dome camera work together to accurately locate the target area to be tracked in the scene, and drive the pan-tilt to control and adjust the camera direction and focal length to achieve precise tracking.

Emergency plan

Click the start simulation button, the number of evacuees changes rapidly, and the line graphs of waiting rescuers, resident personnel, real-time exit numbers, and cumulative exit numbers will also change accordingly.

From the perspective of time, the public crisis emergency management can be divided into four stages: the early warning stage, the preparation stage, the emergency response stage, and the evaluation and recovery stage. We can design the overall framework function of the system based on the simulation of the emergency plan.

Simulation drill visualization

The emergency simulation exercise system simulates the occurrence and development of disasters in the virtual space through the simulation of various disasters and human behavior numerical simulations, as well as the various reactions that people may make in the disaster environment. Develop special emergency plans and on-site disposal plans for all types of possible accidents and all hazard sources at all levels, and clarify the responsibilities of relevant departments and relevant personnel in each process before, during, and after the incident.

Personnel task scheduling

Connect to the venue’s task scheduling system and replace the traditional personnel reporting and feedback mechanism through a data-driven approach. Through real-time personnel task scheduling and dispatch, personnel are dispatched to deal with in time to ensure the timeliness of emergency alert processing. HT visually displays the task name, task subject, attribution specialty, task type, task level, task content and task processing result of task scheduling, which improves the control of task processing inside and outside the venue.

Based on this, managers can form a complete emergency organization, management and command system; a strong emergency engineering rescue support system; a comprehensive coordination and freely responding mutual support system; a sufficient disaster preparedness and supply system; an emergency team that reflects comprehensive rescue.

Summary

Recalling the 2008 Beijing Olympics, relying on the three concepts of "Green Olympics, High-tech Olympics, and Humanistic Olympics", we worked hard to realize the strategic concept of "New Beijing, New Olympics", which not only created a batch of world-class material heritage, but also formed Precious spiritual qualities.

With the continuous development of science and technology, the smart stadium can monitor the flow of people, safety, and environment in the sports venue in real time through the multi-function linkage of three modules: safety management, intelligent control, and big data analysis. Through the HT visualization system, online management of all sports venues such as access control, lighting, monitoring, and broadcasting equipment is realized. Integrating data with traditional elements will help companies change profitability and create a digital space.

Use more activated data to explore the management of the smallest management unit. Build thousands of intelligent entities, and finally form a large-scale intelligent entity. Expand from a building to a street, a district or even a city, and comprehensively promote the digital transformation of the city.

From the perspective of national strategic layout, digital development will be the main theme of economic development in the next 15 years. The "14th Five-Year Plan" and the 2035 long-term goal outline emphasized the need to "welcome the digital age and activate the potential of data elements." In the field of infrastructure, it is necessary to accelerate urban renewal and the intelligent upgrading and transformation of traditional infrastructure, promote the transformation from the Internet of Everything to the Intelligent Connection of Everything, and in-depth advance the digital transformation of all factors. Tupu conforms to the trend of the times and proposes many solutions for intelligent connection of all things.

Visualization solutions require the help of modern technologies such as the Internet of Things, big data, cloud computing, and artificial intelligence to form a smart venue with real-time perception, scientific decision-making, efficient operation, and intelligent monitoring.

Not only stadiums, archives, exhibition halls and other places can use the HT visualization technology of Tupu Software, combined with GIS, BIM and other technologies to improve the efficiency of operation and maintenance personnel and the green and intelligent development of venues and exhibition halls.
