As a region of double Olympics Winter Olympic venues in Chaoyang District Actively practice the concepts of "scientific and technological Winter Olympics" and "green winter Olympics" Transformation and upgrading of facilities and equipment with many "black technologies" Welcome the Winter Olympics Ice cube This "big screen" is "synchronized" with the curling track The smart screen is in the grandstand on the east side of the stadium, covering an area of nearly 170 square meters. Using the "curling trajectory capture" technology, it can not only show the real-time pictures of the four bases in real size, but also draw the motion curve in real time when the athletes throw the curling. It has many advantages, such as improving the viewing experience and assisting the athletes in observation and judgment. In the buffer zone, pass "confidential" with "cabinet" In order to do a good job in epidemic prevention and control, "ice cube" has placed two "intelligent disinfection cabinets" in the buffer zone between the closed-loop management area and the non closed-loop management area. For some important documents that must be transmitted in the closed-loop management area and non closed-loop management area, the staff will put the documents in the intelligent disinfection cabinet for killing. People on both sides can effectively transmit without contact, eliminating the possibility of pathogen transmission. Don't wait in line. You must enjoy the robot meal delivery! During the competition, a number of intelligent robots will be used in the "ice cube". They will be distributed throughout the venues to carry out cleaning and killing, mobile temperature measurement, epidemic prevention supervision, guidance and intelligent distribution, so as to provide intelligent and contactless services for the team members and staff. Everyone in the venue uses this "band aid" All the staff of "ice cube" wear intelligent body temperature stickers. Through the front-end intelligent thermometer and relevant management system, the body temperature paste can realize remote, real-time and global body temperature monitoring for the wearer, so as to lock the people with abnormal body temperature accurately, quickly and in real time. The National Stadium The audience can "scan the code" to find a seat The national stadium has enabled the location service technology of indoor and outdoor integrated non source facilities, and applied geomagnetic navigation and electronic fence to realize indoor high-precision navigation and obtain the location information of personnel in the venue in real time. At present, some seats in the seat area have been upgraded. After getting their tickets, the audience can scan the code at the venue to accurately locate their position. More than 5000 fluorescent rods "flicker collectively" in the stands In order to create a warm competition atmosphere, the venue sports display team designed a gorgeous light show. More than 5000 grandstand fluorescent rods based on cloud interconnection technology flicker collectively. Through the cooperation of music and ice projection, a gorgeous audio-visual feast is created on the ice. Even if there is no audience, the scene is full of atmosphere. The "fog" sprayed by the robot can disinfect The Geely water atomization disinfection robot in the venue adopts ultrasonic atomization to atomize the disinfectant into small particles with an average particle size of less than 10 microns and spray them in the air, which has a good disinfection effect and is more suitable for the disinfection of indoor confined space. By building a map for it, setting its route and determining its disinfection area, it can complete the daily disinfection work in the specified area at the specified time. These prevention and control "weapons" are all useful Molecular sieve air disinfector, candela technology intelligent service robot and aerosol detector are also "weapons" for science and technology prevention and control of the National Stadium, which can provide a safe environment for all personnel from multiple angles. Brush your ID card and complete 7 checks in one second In addition to intelligent robots and disinfection service stations, the "intelligent safe access management system" only needs to brush its ID card to complete the verification of 7 access information in one second. Within 5 minutes, maxillofacial trauma was diagnosed It is worth mentioning that the comprehensive prevention and treatment vehicle for maxillofacial trauma has become the "smart cabin" of the Ice Hockey Hall, which can complete the on-site imaging examination and artificial intelligence diagnosis of maxillofacial trauma in 5 minutes. After review by professional doctors, the diagnostic accuracy of artificial intelligence is more than 96%, which is helpful to improve the efficiency of on-site diagnosis and treatment of maxillofacial trauma. National speed skating Hall Here is the "fastest" and "most power-saving" ice The national speed skating hall adopts the advanced carbon dioxide transcritical direct cooling ice making technology. Compared with the traditional ice making technology, it can save nearly 2 million kwh of electricity every year, which is equivalent to the monthly electricity consumption of 6000 families in Beijing. The application of this technology also allows the temperature difference of the whole ice surface to be controlled at 0.5 ℃. The smaller the temperature difference is, the more uniform the hardness of the ice surface is, and the smoother the ice surface is, the more conducive it is to sliding. This is the origin of the reputation of "the fastest ice" of "ice ribbon". At night, the cool lights are particularly bright The science and technology of "ice ribbon" is also reflected in the lighting and sound effects. The Olympic Games have extremely high requirements for sound. The average value of language clarity is 0.5, while the average value of "ice ribbon" has reached 0.6, exceeding the Olympic standard. One line, control field constant temperature and humidity There is a thin long "line" hanging from the ceiling in four directions above the "ice ribbon". This is not an ordinary line. It can monitor the temperature and humidity in the museum in real time and transmit the data to the venue control system in real time. The control system will adjust and control at any time according to the set standards to keep the most appropriate and best comfort of the whole venue. 1g files will be downloaded in a few seconds Based on 5g high-speed network, the maximum downlink rate of "ice ribbon" can reach 900m per second, and the uplink rate can also reach 200m per second. Files of 1G size can be downloaded in a few seconds. 5g also provides convenience for media services. The mixed interview area has realized remote interview through cloud broadcasting, which not only ensures the interaction between the news media and athletes, coaches and managers in the closed-loop management area, but also provides security for epidemic prevention. After the amazing 2008 Chaoyang District has experienced 13 years of high-quality development Stand in the center of the Olympic stage again Will honor the "covenant of ice and snow" to the world And present a grand event of "science and technology Winter Olympics" I'm looking forward to it!
