The Beijing Winter Olympics are about to kick off, preparations are steadily advancing, and the eyes of the world have been focused on this upcoming ice and snow event. It is worth mentioning that the "Science and Technology Winter Olympics" as a key project throughout the Beijing Winter Olympics, and in the venues, operation, command, security, medical care, meteorology, transportation, broadcasting and other key scenes played a pivotal role, the Beijing Winter Olympics can be said to be a "armed" by scientific and technological innovation achievements of the grand event.
A variety of robots stand out
Robots shuttling back and forth around the main media center of the Winter Olympics, hotels and other places attract people's attention.
The most concentrated place for robots at the Beijing Winter Olympics is the main media center restaurant, where each dish is made by robots. There are transparent glass tracks above the head, which are transported by machine to ordering guests after cooking, like a crane game, where meals fall from the air to the eye, and guests only need to open their hands to take them.
In addition to the smart "chef" who cooks the meal, there is also a cool smart bartender in the smart restaurant. With the help of a dexterous "arm" to take a cup, ice cup, set a cup, and like a bartender to complete the complex mixing, shaking and other actions, it can make a variety of colorful, unique flavor cocktails, will provide a relaxing and happy time for media reporters after busy time.
In addition, atomization disinfection robots, ultraviolet disinfection robots, and "small white" inspection robots are about to take up their posts, and environmental disinfection, prevention and control inspections, and personnel disinfection can be completed only by these intelligent devices.
There is a chubby "small belly" on the round chassis, a "small fan" on the long neck, while moving rapidly at a speed of 1 meter per second, spraying fog disinfectant outward for disinfection operations, this interesting little guy is the atomization disinfection robot that helps prevent and control the epidemic in the Winter Olympics.
This atomization disinfection robot can kill 36 square meters, which can kill more than 1,000 square meters at a high level at a time, and the endurance is 4 to 5 hours. According to the technical staff, the atomization disinfection robot can hold 16 liters of disinfectant at a time, spray the agent through the four-way spray head overhead, and operate the robot with only one mobile phone APP. "This little guy also has vision sensors and lidar on the chassis, which is equivalent to two small eyes. By using lidar to scan the road ahead, vision sensors identify road conditions in more complex environments, easily avoid obstacles and perform disinfection tasks. ”
Back at the hotel, as soon as you enter the lobby, you will encounter cleaning robots that are cleaning the floor with mops, and they are cleaning while avoiding pedestrians. If you play a prank and don't avoid it, the robot won't "bump into it" with you, and it will quickly adjust its direction and continue to move forward.
The head of the inspection robot "Xiaobai" is equipped with non-contact hand disinfection equipment. When it patrols, it can stop anytime and anywhere to provide hand sanitizer for people. During the 30 seconds it stays, if hand sanitizer is required, the user simply places his hand on the infrared sensing part of the disinfection device above his head to obtain a hand-sanitizer gel. In addition, the "Xiaobai" inspection robot will also enter warm prompts in advance according to the needs of the venue, such as: there are × minutes left in the countdown to the game. Remind spectators not to miss the highlights of the event.
Smart trash can "can be loaded, can run and recharge"
"May I ask, where can I throw away the garbage?" Perhaps this is the first question that some media reporters asked to the volunteers next to them after walking into the huge main media center. Indeed, and the previous garbage cans set up relatively obvious difference is that this time in the main media center of the garbage cans look a little "low-key", the gray barrel body makes people at first glance more like they look like air purifiers, and after pointing out a closer look, only to find that these garbage cans are really full of technology.
These smart trash cans are distributed on the first floor of the lobby of the main media center, and the number of them can reach dozens. They are also divided into "recyclables" and "other garbage" trash cans. When someone approaches and lifts the garbage in their hand, the machine automatically opens the top cover to make it easier for everyone to throw, and once the trash can is full, they will follow the route back to the designated area for dumping, and then return to "work". In addition, if the power is out, they will also "replenish" themselves to the preset point.
This kind of intelligent garbage can not only ensure the beauty and cleanliness of the relevant area, but also improve the efficiency of the clean environment, which can be described as killing two birds with one stone.
For the first time, the Winter Olympics used a smart bed
According to the Global Times, the "black technology bed" specially installed for the athletes at the Chinese Winter Olympics is not only very comfortable, but also can be intelligently controlled, and an American bobsleigh athlete, Summer Brecht, shared her experience on social platforms. In the video, she marvels at the bed the whole time, saying that she can't believe it, it's just amazing.
As the video became popular on social platforms, the US media "New York Post" also reported on this "black technology bed". It is reported that this "smart bed" is very powerful, can fully take care of the athlete's spine, only need to be set to the appropriate sleeping angle through remote control, the memory foam in the mattress and smart sensors can provide massage and other services for athletes. Not only that, but if the sleeping position is uncomfortable and the athlete snores, the smart bed can also help adjust the height of the head for relief. This is also the first time that the previous Winter Olympics have been equipped with a "smart bed", which is completely different from the cardboard bed of the Tokyo Olympic Games.
The Smart Mobile Pod will be enabled
Medical protection is an important part of the success of sports events. The competition venues distributed in the three major competition areas, the continuous schedule, and the difficult ice and snow events have put forward high requirements for the medical security work of the Winter Olympic Games.
Led by Peking University Stomatological Hospital, the special research results of the national key research and development plan "Science and Technology Winter Olympics" intelligent mobile square cabin is the first artificial intelligence-based frostbite and maxillofacial trauma mobile intelligent diagnosis and treatment platform in China. During the Beijing Winter Olympics, it will escort athletes in the Winter Olympic venues and act as an "emergency doctor" on the ice and snow arena.
The intelligent square cabin covers an area of less than 20 square meters and is equipped with horizontal cone beam CT, frostbite facial data acquisition system, portable intelligent cardiopulmonary resuscitation machine, ECG monitor and other key diagnostic and treatment equipment for on-site diagnosis and treatment of frostbite and maxillofacial trauma, which can realize the close integration of traditional medical technology with modern high technology. Peng Xin, a professor of oral and maxillofacial surgery at Peking University School of Stomatology, said that after ct examination of athletes in the intelligent cabin, the artificial intelligence diagnosis and treatment platform only takes 30 seconds from the introduction of CT images to the generation of diagnostic reports, ensuring that athletes can be effectively treated in the golden window of treatment.
Armpit bandpieces monitor body temperature at all times
As a test venue for the ice hockey project, there are more than 600 staff members in the Wukesong Sports Center, how to do a good job of their body temperature monitoring, so that there is a timely detection of the epidemic, a "armpit Band-Aid" plays an important role. According to Yin Jinshu, deputy director of medical treatment and epidemic prevention at wukesong sports center, those who need to be tested only need to attach a finger-sized thermometer to the armpit or upper arm with a band-aid, and bind the device on the mobile phone App, and the temperature data changes of the subject will be clearly displayed on the mobile phone page, and can be automatically measured and automatically reported to the background. This wearable thermometer and the "clairvoyant" system for epidemic prevention and control provide important scientific and technological support for epidemic prevention and control.
Compared with the traditional method of body temperature detection, the "armpit bandage" thermometer has several technical advantages. First of all, the thermometer has a higher temperature measurement accuracy, and the detection accuracy of the similar temperature sticker in the United States is 0.1-0.2 °C, while its detection accuracy reaches 0.05 °C. Secondly, the power consumption is lower, and the "armpit band-aid" thermometer can measure the temperature continuously for more than 10 days on a single charge.
Today, the multi-sign sensing device, which is an upgraded version of the "Armpit Band-Aid", has been distributed to the Capital Stadium complex. Combined with the big data early warning platform, it can realize 7 monitoring and early warning of body temperature, heart rate, breathing rate, blood oxygen, exercise, blood pressure and sleep. If any indicator of the staff wearing the device is abnormal, the system will automatically alarm.
Aerosol detection system "on the job"
Aerosols with a diameter of less than 100 microns and a transmission distance of more than 1 meter can be inhaled directly into the lungs, which is one of the important ways of transmission of the new crown pneumonia virus.
In order to monitor the aerosols in the air, researchers from Tsinghua University, Peking University, the Institute of Pathogenic Biology of the Chinese Academy of Medical Sciences, and the Changping Laboratory carried out emergency research and jointly developed a public space bioaerosol new coronavirus monitoring system. The system is capable of collecting and detecting bioaerosols present in the air with up to 10 times the sensitivity of conventional methods.
The aerosol collector is small and lightweight, suitable for use in small and confined spaces such as warm-up rooms and referee rooms, and can collect aerosol particles within 12 cubic meters in 30 minutes and collect them into a sampling tube.
Li Bao, a graduate student at Tsinghua University School of Medicine, demonstrated the process by attaching gloves and fixing the collection tube to the collector. In the middle of the bioaerosol sampler is a specially designed cavity in which the air sucked in by the air inlet forms a gas "vortex". After the instrument is started, the air cyclone is directed into the collection tube at a flow rate of more than 400 liters per minute, and particles such as aerosols in the air are thrown into the collection tube.
The collection tube is filled with 4 ml of virus inactivation solution, and once the aerosol contains virus, it will be inactivated to ensure the safety of sampling and subsequent testing personnel.
At present, many venues of the Beijing Winter Olympic Games have arranged such aerosol collectors and set up temporary testing stations to provide comprehensive aerosol new coronavirus testing guarantee for the Winter Olympics.
The "little world" in the smart sleep pod
During the Beijing Winter Olympics, in order to facilitate the rest of media reporters with work jet lag, the second basement floor of the main media center is equipped with 20 high-tech rest cabins. The sleeping and resting cabin is equipped with beds, desks and other supplies to meet the needs of journalists resting and working.
In this relatively enclosed space, media reporters can get physical and mental relaxation, and the cabin is equipped with complete facilities, so that people who come to rest do not have to worry about various problems such as epidemic prevention safety or charging equipment.
Scan the code first, then select the duration, and when the "hatch" opens, a private space with a separate bed and table will be revealed. People who have experienced it have reported that the bed material of the sleeping pod is soft, which helps to relax the body, and it also has the function of vibration massage, which can make people get a good rest and adjustment. Considering that many people come here to choose to take a nap, the lights in the house can also be adjusted, and the change of light from light to dark also helps everyone fall asleep as soon as possible. In order not to delay the work, the experiencer can also set an alarm clock, and when the time is up, the flat bed will slowly rise, playing a role in a "wake-up" service.
In addition, in order to ensure the safety of epidemic prevention, an air purifier is also installed in the sleeping and resting cabin, and the hollow design is carried out on the top to ensure air circulation.
According to the relevant person in charge, these 20 sleep and rest cabins are completely free for the media to use, these rest cabins will soon enter a dormant state in the case of no one to use, basically only consume about one kilowatt hour of electricity a month. This also reflects the concept of science and technology and energy conservation and environmental protection of this Winter Olympic Games.
Winter Olympics broadcast full "to the clouds"
The Beijing Winter Olympics will be broadcast globally through Alibaba Cloud, bringing more than 6,000 hours of exciting content. This would be another major technological advance since satellite television began broadcasting at the 1964 Olympics. Olympic Broadcasting will no longer rely solely on satellite transmission, but will also reach billions of viewers around the world through the Olympic Broadcasting Cloud supported by Chinese technology company Alibaba Cloud. The live broadcast of the race will use the world's first 5G+8K broadcast truck.
According to reports, this cloud broadcast platform has been prepared for 4 years. In 2018, Olympic Broadcasting Services cooperated with Alibaba Cloud to develop OBS Cloud, the olympic broadcast cloud, which was first put into use at the 2021 Tokyo Olympic Games and undergoing a major upgrade at the 2022 Beijing Winter Olympics, realizing live HDTV broadcasting and live broadcasting on online channels at the same time on the cloud.
It is worth mentioning that with the full coverage of 5G signals in the venue and the improvement of cloud broadcast technology, the interactive multi-dimensional viewing experience technology of ice and snow projects has reached a new height. The interactive multi-dimensional viewing experience system ("free perspective") realizes a new viewing experience. In the process of watching the game, the user can continuously change the viewing point, and then see the same event from different angles.
At present, Alibaba Cloud has completed the final round of global network testing of the broadcast cloud, preparing for the opening ceremony of the upcoming Winter Olympics and the broadcast of the event. At the same time, Alibaba Cloud has also added exclusive cloud network channels for broadcast television stations in Russia, Brazil, Mexico, Japan and other places to ensure that 4K/8K content can be transmitted remotely and with high quality, and reduce latency by 30%.
With the continuous integration of a large number of scientific and technological elements, it will not only greatly improve the management level of the Winter Olympic Games, but also stimulate people's sense of innovation in clothing, food, housing, travel, entertainment, learning, creation and other aspects, and promote enterprises and R & D institutions to use more innovative achievements in the development of the sports industry. This move will not only help the Athletes of the Winter Olympics to create good results, but also contribute to the high-quality development of the mainland economy in the future.
