Compared with the Pyeongchang Winter Olympics and the Tokyo Summer Olympics, the Beijing Winter Olympics achieved large-scale commercialization of 5G for the first time: for example, the "5G+8K ultra-high-definition video + artificial intelligence algorithm" technology used to help coaches accurately correct the athletes' posture during training; the "5G smart first aid" that allows injured athletes to "get on the train and be admitted to the hospital"; the "5G+ cloud direct (transliteration) backpack" that helps journalists and videographers get rid of the shackles of wired lines and push streams while interviewing live...
The reporter learned from China Unicom, the official communication service partner of the Beijing 2022 Winter Olympic and Paralympic Games, that in fact, these 5G "black technologies" have been landed in the process of digital transformation of Shanghai city, and they are not far away from you and me.
Artificial intelligence corrects athlete posture, and Shanghai industrial testing uses this technology
On the eve of the opening of the Winter Olympics, in the preparation training of the national team for steel frame snowmobiles, figure skating, ski jumping and other projects, there is a technology called "5G +8K ultra-high-definition video + artificial intelligence algorithm technology" that helps coaches to no longer rely solely on the naked eye and old experience when training, and can more accurately correct the posture of athletes.
Shen Hongbo, secretary of the party committee and general manager of Shanghai Unicom, who completed the torch relay at the top of the Great Wall, as the torch bearer of the 21st Winter Olympics in Badaling, Yanqing, Beijing, told reporters that in Shanghai, the "5G +8K ultra-high-definition video + artificial intelligence algorithm" technology has tested the water in the field of industrial testing. Shanghai Unicom, together with Shanghai's aircraft manufacturers and Shanghai shipbuilding companies, has used this technology for aircraft fastener testing and ship steel plate surface defect detection.
Shen Hongbo served as the torchbearer of the 21st Winter Olympics in Badaling, Yanqing, Beijing.
"Originally, these two jobs relied on the naked eye, were inefficient, and inevitably misjudged. Nowadays, the 24-hour tireless 5G camera transmits 8K high-fidelity ultra-high-definition images to the private cloud, and completes the task of intelligent identification classification and measurement of defects in the cloud, and then transmits the detection results back to the intelligent terminal working on the site through the 5G network to assist the quality inspectors. ”
The data shows that after the use of this technology, the efficiency of aircraft fastener detection is increased by more than 5 times; the detection rate of pockmark defects on ship steel plates can reach more than 98%, avoiding defective plates flowing into the production stage of the back road, and saving a lot of rework processing costs every year.
The "Construction of a Smart Medical Emergency Rescue System based on a 5G Network in a Mega Urban Area" was launched in Shanghai
Some of the Winter Olympics events are fast and difficult to rescue, and if athletes are accidentally injured, how to quickly achieve first aid is crucial. The Beijing Emergency Center, a designated emergency transport agency for the 2022 Beijing Winter Olympics, joined hands with China Unicom to upgrade ordinary ambulances into 5G smart ambulances. Shen Hongbo introduced, "First responders can transmit relevant data and information in the car to the emergency center in real time through the 5G emergency gateway in the car, based on the 5G network, to achieve data interoperability and sharing." Hospital experts can 'face' patients through ultra-high-definition audio and video to judge the condition, and carry out remote first aid, remote consultation and remote guidance, saving valuable time for life assistance. ”
Beijing Emergency Center and China Unicom have upgraded ordinary ambulances into 5G smart ambulances.
According to reports, in Shanghai, led by Ruijin Hospital, Shanghai Shenkang Hospital Development Center, Shanghai Public Health Clinical Center, Shanghai Medical Emergency Center and Shanghai Unicom and other units jointly participated in the national new infrastructure field project "Construction of Smart Medical Emergency Rescue System Based on 5G Network Mega Urban Area" has been launched.
"Based on new technologies such as 5G, cloud computing, Internet of Things, and artificial intelligence, this smart medical application platform can not only carry out remote emergency rescue and aviation medical rescue command, but also carry out remote real-time multidisciplinary consultation, remote imaging diagnosis, remote pathological diagnosis, high-definition remote teaching, remote mobile room rounds and other smart medical treatment, which will help Shanghai build a three-dimensional urban emergency rescue network that combines peacetime and wartime."
"5G + cloud direct (transcast) broadcast" allows online training to get rid of the shackles of "electrified classroom"
In the past, TV media used large microwave broadcast vehicles when broadcasting large events, which was not only expensive, but also required a large number of personnel to serve in the production and broadcasting process... At this Winter Olympics, the "5G + cloud direct (transcast) broadcast" technology solved these problems. "5G + cloud direct (retransmission) broadcast" adopts the concept of lightweight, the front-end collection part only uses a small number of personnel and equipment, and uploads the video source to the cloud, and most of the personnel are placed in the editing, production and broadcast of the backend.
The audience can see on the TV screen of the Winter Olympic Stadium that the cameraman has a self-developed "5G + cloud direct (broadcast) broadcast" backpack on his shoulders, while collecting the picture, while real-time backhaul. Especially when live streaming snow competition sports, the cameraman carries a "5G + cloud straight (trans) broadcast" backpack weighing less than 1 kg and a standby time of up to 4 hours, and pedals skis, which is beautiful and sassy.
The staff explained the use of 5G cloud transfer (direct) broadcast backpacks to reporters participating in the Winter Olympics coverage.
It is worth mentioning that the 5G cloud straight (transposed) sowing backpack is also equipped with graphene self-heating insulation sleeve, which can increase the working environment temperature of the backpack by 20 degrees Celsius to prevent "frostbite" by the external environment of the Winter Olympics.
According to reports, since the second session of the Expo, Unicom's "5G + cloud direct (broadcast) broadcast" backpack has been used by Shanghai TV media people to get rid of the shackles of microwave transmission and carry out on-site broadcasting of the Expo.
In addition to being used in television media, "5G + cloud direct (transcast) broadcasting" has also been used in Shanghai's high-end distance education for overseas. At the end of last year, the Shanghai China Pudong Cadre College was entrusted by the Ministry of Commerce to provide remote training of the "Governance Online Seminar" to overseas, and was technically supported by Shanghai Unicom. "'5G + cloud direct (transcast) broadcast' technology allows distance education to be free of traditional electrified classrooms, only a high-definition camera and a microphone, which greatly reduces costs." Shen Hongbo said, "Allowing 5G applications to continue their value in the post-Winter Olympic era will be an important issue for Shanghai Unicom to help Shanghai's urban digital transformation in the next step." ”
