At the Beijing Winter Olympic Games, the operation support of the three competition areas hundreds of kilometers apart was like an arm in the arm. The millisecond time synchronization was realized among the posts at the opening ceremony. The “digital bird’s nest” optimized the energy demand and achieved 30% energy saving… From “command brain” to “nerve center” and “sensory endings”, the application of advanced technologies such as the Internet of things, big data and artificial intelligence, It ensures the smooth, efficient and intelligent operation of the huge Winter Olympic command system.
Three competition areas command and dispatch “a game of chess”
This winter Olympic Games involves two cities and three competition areas. The geographical space span is large and the situation is changeable. Coupled with the needs of epidemic prevention and control, it is not easy to realize the “one game of chess” coordinated command of the three competition areas. However, Chen Tao, a researcher at the Institute of public security of Tsinghua University, led the research and development of the “situation awareness and operation command and guarantee system for the Winter Olympic Games”.
Located on the large screen of the main operation center of Shougang, the overall progress of the event, important activities and accidents can be seen at a glance. The node arrangements of training and events in each venue are clearly arranged in the form of time axis. The system also connects all competition areas, key business areas and urban operation guarantee institutions, and enhances the ability of information sharing and coordination.
“The system can also provide countermeasure reference in the mode of scenario deduction.” Chen Tao introduced that the system has realized the convergence, integration and intelligent analysis of cross domain space-time data such as venues, meteorology, events, personnel, transportation, medical treatment and epidemic prevention, found problems and risks earlier, and integrated technologies such as big data, cloud computing and hybrid reality. The three competition areas have realized unified command, coordination and cooperation under the command of digital and intelligent systems, Build a “Winter Olympics brain”.
Chen Tao said that the key to the construction of the operation command system lies in the unity of standards, standardized operation, seamless connection and organic integration. The successful application of the system in the Winter Olympic Games can provide a model for all-round intelligent and efficient collaborative management of large-scale events in the future.
Space platform becomes the command center of the opening ceremony
Behind the beautiful opening ceremony of the Winter Olympic Games is the tacit cooperation of tens of thousands of people, and orderly promote the performance and ceremony process according to the established time node. Under the stage, the commanders must master all the operation guarantee data of venues such as power, communication and transportation to deal with emergencies. A unified command center is essential.
Aerospace new Long March Avenue Technology Co., Ltd. of the first Academy of China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group undertook the task of developing the command and monitoring system for the opening ceremony. He Feng, the company’s product director, introduced that the system is based on the independent, safe and controllable “Long March cloud” platform, combined with the research and development of Internet of things, big data and other technologies, and is composed of command information system, video monitoring system and traffic and venue information monitoring system. In addition to ensuring the collaborative work efficiency between various posts, the system can also monitor the main areas, key equipment, personnel streamline, wind, water, electricity, heat, air quality, weather conditions and other information in real time.
“Each post can achieve millisecond time synchronization to ensure the perfect cooperation between each link.” He Feng said that the system intuitively helps the chief director and dispatchers at all levels control the overall situation, quickly adjust the command and operation process according to the on-site process and emergencies, and realize the seamless connection of process nodes. The system also has the ability to intelligently check and judge the process timing and logic errors, so as to improve the command efficiency. “Just like the launch system of China aerospace, all systems cooperate with each other to ensure that the task is safe.”
“Smart brain” makes the bird’s nest save energy by 30%
In order to ensure the smooth progress of the opening and closing ceremony of the Winter Olympic Games in the bird’s nest of the National Stadium, combined with the needs of venue operation, Beijing Intelligent Building Technology Co., Ltd. has developed a “digital twin operating system”, which uses IOT equipment combined with 5g, Internet of things, artificial intelligence and other technologies to integrate the data of various points in real time, analyze and judge, and give the optimal solution.
“We are to enable the bird’s nest to digitally perceive and operate, so it is called ‘digital twin’.” Zhu Jie, President of Beijing Intelligent Building Technology Co., Ltd., said that the system focuses on the healthy environment of the building body, energy optimization, equipment monitoring and early warning, and intelligent security. More than 8000 IOT devices go deep into the end of the bird’s nest to better perceive the operation status of venues such as equipment conditions, environmental changes and crowd information, and can carry out operation management, analysis and prediction through artificial intelligence technology.
Zhu Jie said that as a typical large-scale public building, the energy use demand of the bird’s nest fluctuates in different scenarios such as daily operation and major activities, and the energy demand in the internal area is not balanced, so it is difficult to achieve optimal adjustment by manpower. The digital twin system can monitor regional energy consumption and demand in real time, conduct statistical measurement and analysis, push energy consumption and energy-saving strategies, and carry out dynamic energy matching. Without sacrificing comfort, “smart brain” can save 30% of energy consumption for the bird’s nest. Our reporter Liu Suya
