Within the closed loop, 5G food delivery robots are also being used in food delivery services in some areas to minimize human contact. It adopts 5G indoor multi-functional cloud technology, integrates 3D semantic maps, combines multi-modal autonomous navigation and obstacle avoidance intelligent walking capabilities such as lidar, ultrasound, cameras, infrared sensors, etc., and can realize independent planning paths, independent obstacle avoidance, and flexible completion of intelligent food delivery services.
Entering the National Aquatics Center from the media channel, the first thing to pass through is the security gate. Here, the face recognition security inspection system automatically compares the information on the personnel and the documents they wear, and after the information is consistent, it is broadcast "passed" and released. Then, at the second epidemic prevention security checkpoint, the automatic temperature measurement system monitors the body temperature of the passers in real time and displays it on the big screen. After passing, it is the last epidemic prevention security check outside the venue. Volunteers wearing blue vests checked the 48-hour nucleic acid test certificates of the admission personnel one by one, and confirmed negative before being released.
Entering the venue, on the left-hand side is the epidemic prevention station, which is placed with alcohol wipes, masks, thermometers, disinfectant and other epidemic prevention supplies, and there is an automatic washing mobile phone with hand sanitizer on the side.
The entrance to the stadium is also equipped with an epidemic prevention station and automatic mobile phone washing. The reporter found that from the entrance of the security checkpoint outside the venue to the entrance of the stadium, a total of 4 epidemic prevention stations and multiple automatic mobile phone washing stations were set up, and there were prompt signs printed everywhere with "please wear a mask", "please maintain social distancing" and "wash your hands and disinfect". Entering the arena, the media viewing area is in the audience seat, with only one entrance and exit, which is separated from the venue and the field staff activity area by the transparent partition, and is in an independent position.
In order to do a good job in epidemic prevention and control, the venue also introduced an epidemic prevention handheld terminal to verify the status of the health code. As long as the admission personnel brush the ID card on the handheld terminal, if the health code is normal, the handheld terminal will immediately print out a certification slip. In places where it is necessary to view the health treasure, the admission staff can pass as long as they show the receipt, avoiding the inconvenience of repeatedly clicking on the mobile phone to view the health treasure.

Digital large screen to create a "folding space"
It is 24 meters long and 7 meters wide, and constantly captures the scene of the competition. In the arena of the "Ice Cube", a new "giant" smart screen attracted the special attention of invited media reporters, referees, athletes, etc.
This large screen is a unique design of the new exploration of "Ice Cube", which is not only larger - about 170 square meters, which can show the real-time picture of the 4 base camps in real size, but also, while the athletes throw curling, the large screen will also draw a curve in real time, which is the "curling track capture" technology that the stadium team is testing and perfecting. This innovative application has many advantages, such as improving the spectator experience and assisting athletes in observation and judgment.
"Curling competitions are known as international 'chess' on ice, although there is no fierce physical confrontation, but it is also a double contest of intelligence and physical strength, with both skill and strategy." Yang Qiyong, deputy director of logistics of the national aquatics center venue operation team, introduced that the running trajectory of curling is an important aspect of the athletes' competition strategy, and the scene has this large screen, which can not only show the curling trajectory to the audience, help them interpret curling sports, but also let them pay attention to the strategies and tactics of the two sides of the competition while appreciating. "The large screen plays the role of 'folding space', which can enrich the audience's viewing perspective and provide a basis for athletes to judge when implementing competition strategies."
"The first time I saw a screen like this on the field showing the conditions and curling trajectory, it was very useful, it played a positive role in my performance on the field." One of the participating athletes said after the game.
Yang Qiyong said that at present, the leaders and coaches of various teams recognize the existence of the big screen. The data captured by the smart big screen and its analysis will also be provided to the team in the form of data analysis after the game.

Control system achieves "smart venue"
The big screen is just one aspect of Ice Cube's technological innovation. In order to actively practice the concept of "Science and Technology Winter Olympics", in the process of transformation from "Water Cube" to "Ice Cube", a large number of high-tech applications have enabled the National Aquatics Center to realize the gorgeous transformation from ordinary venues to "smart venues".
"Water ice conversion" requires that the back-end machinery and equipment and control system of the venue have the ability to convert with the functional needs of the venue. In order to ensure that the indoor environmental conditions of ice cube meet the requirements of curling competitions, the venue has set up a building equipment management system led by more than 4,000 sensors, which can monitor and control changes in temperature, humidity, PM2.5 concentration and so on in the venue in real time.
Yang Qiyong introduced that the new large screen in the control room under the venue is an intelligent building operation and maintenance management platform, which can display the operation of the ice making system, dehumidification system, energy system, ticketing system, etc. in real time, and implement intelligent regulation of the equipment system of the venue. Visual energy control also effectively controls the energy consumption and carbon emissions of the venue.
In addition to the control system, the intelligent technology of "Ice Cube" can be seen everywhere, such as the temperature detection sensor with Bluetooth system at the entrance. These machines not only read and collect data without contact, but also provide intellectual support for venues to improve service efficiency through data management and utilization.

Welfare vehicles serve disabled athletes to travel
On the morning of the 23rd, the representative teams of the 2021 World Wheelchair Curling Championships set off from the China Sports Management Center for the Disabled and took a welfare car to the competition venue "Ice Cube". These welfare vehicles were converted from buses specifically to ensure the travel of disabled athletes.
The athletes of the Chinese team came out of the management center one after another, and after the security guards of the management center saw it, they immediately put down the barrier-free pedals of the public transportation operation vehicles and connected them to the customized pedals. "The pedals of the bus are shorter and steeper when lowered, but when the customized pedals are connected, the slope becomes slower, and the athletes can easily get on the bus in wheelchairs." According to the relevant staff of the Traffic Operation Support Group of the Beijing Division (Chaoyang) Organizing Committee of the "Meet in Beijing" series of winter sports events, a total of 6 customized pedals were placed in the management center, which can meet the centralized travel of multiple representative teams.
After the athletes turned their wheelchairs to the car, they stopped in the wheelchair parking area, and the team members helped them to anchor the wheels. One welfare vehicle can accommodate 6 wheelchairs at the same time, of which two parking areas are equipped with 4 anchors to secure the wheelchair and prevent it from sliding forward when braking.
"Athletes travel in 'special vehicles', and the vehicles of each representative team are fixed." According to the relevant staff, the management center has a total of 15 welfare vehicles, 12 representative teams each team, during the race will take the same car back and forth, the remaining 3 as a backup, used to meet the needs of temporary cars, to ensure that the car is used at any time, at any time there is a car.
After the welfare car arrives at the Ice Cube, the staff will also lift the custom pedal out and place it in front of the car door to facilitate the athletes to get off the car. "Wheelchairs can be directly on the welfare car, and there are pedals up and down, which is very convenient." Yan Zhuo, an athlete from the Chinese team, praised the welfare car. During each race, drivers and welfare vehicles wait at the venue until the end of the race before sending the athletes back to the management center. Before departure and after return, the vehicle will be disinfected twice to ensure epidemic prevention and safety.

5G terminals fully support scene services such as venue operation and medical rescue
"The body temperature is normal." Just walked to the temperature measurement area located at the west gate of the "Ice Cube", a "health treasure rapid detection machine" painted with the logo of China Unicom attracted the attention of reporters, which is one of the 5G applications provided by China Unicom in the 2021 World Wheelchair Curling Championship.
The health treasure rapid detection machine has two functions: body temperature measurement and verification of health treasure. After the temperature measurement area, the personnel no longer need to take out the mobile phone to scan the code, only need to swipe the ID card or medical insurance card and the elderly card on the machine to identify the identity, you can show the body temperature, whether to register and the status of the health code.
"It not only meets the requirements of efficiency, but also meets the requirements of epidemic prevention." Chen Gang, the relevant person in charge of China Unicom, introduced that in this competition, China Unicom implemented a number of 5G applications such as the "Meet in Beijing" test activity service network and "cloud interview" for event services.
In order to do a good job in 5G communication support and network support for the "Meet in Beijing" test activity, China Unicom provides 5G, WiFi and other Internet access in key areas such as mixed mining areas and media workshops. The reporter connects to the beijing2022 WiFi network, after entering the registration code on the certificate, you can directly connect to the WiFi in the venue, use 5G for video, pictures and other data transmission, 10G pictures, fingers can be downloaded, very fast. "Media friends can use a safer and more stable network to report on the event." Chen Gang said.
In the post-match interview link, it is also achieved by relying on 5G communication support. Journalists and athletes are located on different floors and areas, each facing a TV screen, and the post-game interview of athletes can be completed through the transmission of 5G signals. Such "cloud interviews" not only respond to the special needs of the work in the field of events under the state of epidemic prevention and control, but also take advantage of the high speed and low latency of the 5G network to efficiently ensure that the interviews between the interviewees and reporters reach real-time transmission.
At the same time, China Unicom also launched a smart command and dispatch system, providing a public network intercom terminal and an exclusive APP for the operation team of the National Aquatics Center, which fully supports the operation support team, volunteer management, venue operation, medical rescue and other scenario services. The reporter learned that there are 71 PUC walkie-talkies in the "Ice Cube", which realizes communication between various fields, and the staff can open the "Ice News" APP to make calls, videos and remote commands to meet the scheduling needs. In addition to meeting the scheduling needs of the venue, the intelligent command and dispatch system also supports the call and visual needs of the operation team across Beijing, Yanqing and Zhangjiakou.
Chen Gang introduced that the batch of 5G application services created by China Unicom will also be applied to the Beijing 2022 Winter Olympics and Winter Paralympic Games, empowering the Winter Olympics of science and technology and the Winter Olympics of wisdom, and demonstrating China's scientific and technological strength.
