However, we dont need to worry about the fact that body temperature detection will make our travel difficult. In the current environment, there are many new technologies that are helping us fight against the epidemic, making our access more convenient, and also making front-line medical care have better health protection.
5g made us a cloud supervisor
Since last year, 5g communication has been applied to public construction. This year, we can also see 5g in the construction of huoshenshan and leishenshan hospitals.
At the top of the building near the huoshenshan hospital, we can see a round surveillance camera working. Thats the eyes of tens of millions of cloud overseers. Through the 5g network 24, we can continuously transmit the construction of huoshenshan hospital.
The Regent is in charge
In fact, as early as the early stage of huoshenshan hospital (January 25), China Mobile, China Unicom and China Telecom have opened the first 5g base station for the hospital, and then realized 4G and 5g network coverage. On January 27, the construction personnel of the two hospitals completed all equipment commissioning and started live broadcasting.

But 5g brought this live broadcast not only speed advantage, but also more flexible equipment laying adjustment. In the past, if wireless network is not used, before live broadcast, the construction team needs to lay optical fiber, build network, assemble equipment, and then transmit high-definition images to various platforms. However, this will increase the difficulty of construction and affect the overall process.
Therefore, in this live broadcast, the live broadcast team uses the 5g + fiber double Gigabit Network transmission scheme, so as to ensure that the live broadcast can be carried out 24 hours a day.

It is an inevitable choice to use 5g for uninterrupted live broadcasting, and it is also a bold attempt by the team. However, as we can see, this live broadcast confirms 5gs help to the transmission efficiency of video media and higher flexibility, and successfully transmits the construction site pictures to the equipment of each audience in front of the screen.
According to first finance and economics, the number of people watching the live broadcast online at the same time exceeded 90 million, and the cumulative number of visitors exceeded 200 million.
In China Mobile, Migu video has been broadcast live to more than 20 mainstream media, such as peoples daily, Xinhua news agency, CCTV news, etc., with a total of 300 million viewers as of February 4.
5g and VR form information epidemic prevention
5g is not only used in live broadcast, but also in temperature detection. At the beginning of the article, I mentioned that the new technology makes our travel more convenient, in fact, it means 5g infrared thermal imaging temperature measurement.

Compared with the traditional manual temperature gun detection, the 5g infrared thermal imaging temperature measurement adopts the non-contact design, that is to say, the equipment can quickly obtain the current temperature data of the personnel for screening just by passing in front of the lens and sensor, so as to avoid the steps of manual test one by one, improve the traffic efficiency, and reduce the cross infection caused by the detention of personnel.

It is reported that through thermal imaging technology and environmental data algorithm, the temperature measurement accuracy of the instrument can reach u00b1 0.1 u2103. With the help of 5g network, the temperature data detected by the instrument will be transmitted to the epidemic prevention control center in time. When the temperature of personnel is detected abnormal, the device will automatically give a warning.
And the whole detection process only takes 0.5 seconds, which is 10 times faster than the manual temperature measurement.

The hospital intensive care unit is the front line of fighting against the disease, and it is also the place where the virus is most transmitted between doctors and patients.
In the severe isolation area of the Second Affiliated Hospital of Zhejiang University Medical College, we can see many newly installed monitoring equipment, but these are not ordinary security monitoring lenses, but the VR remote observation and guidance system installed by China Mobile.

According to the introduction, through these lenses distributed throughout the critical area, medical staff can observe the patients in the critical area at any time through high-definition screen and VR technology, so as to avoid the contact between medical staff and critical patients, and reduce the infection situation that medical staff may appear due to contact with patients.
At the same time, experts outside the second hospital of Zhejiang University can also observe the patients in the critical area through this system. Even in a different place, the expert group can also give a timely diagnosis and treatment plan to help the hospital carry out rescue work.
For the patients families, we can observe the situation of their relatives in the severe isolation area through this system.
Of course, due to the need for real-time high-definition VR picture transmission, this system is also built based on 5g network. Like the infrared temperature detection system mentioned earlier, VR remote observation and guidance system is also one of the applications of information epidemic prevention.
AI reduces diagnosis time to 30 minutes
In fact, in addition to more efficient communication transmission, ai artificial intelligence also plays an important auxiliary role in this epidemic.
On February 1, Zhejiang CDC launched the automatic whole genome detection and analysis platform to compare the nucleic acid detection currently used. According to the AI algorithm, the system can carry out the whole genome sequence comparison of virus samples of suspected cases, not only to detect the partial part of the virus gene, so as to prevent the detection of the virus from missing due to variation.
New coronavirus structure
According to the surging news, the automatic whole genome detection and analysis platform is jointly developed by aridamo Institute and Jieyi Biotechnology Co., Ltd., and supported by the analysis algorithm provided by Ali. Jieyi biology is responsible for the full-automatic high-throughput sequencing database builder. Through the analysis algorithm of distributed design, the system splices the sequenced results (debruijn algorithm is used in the splicing stage uff09In a short time, the complete structure and diagnosis results of the virus were obtained.

On the other hand, Shanghai Public Health Clinical Center recently launched the new type of coronavirus pneumonia intelligent image evaluation system, which uses AI image algorithm to carry out automatic comparison, diagnosis and disease quantitative analysis and evaluation of CT images through artificial intelligence whole lung quantitative analysis technology.
In addition, the system can grade and analyze the severity of patients according to the examination results, provide multi-dimensional decision-making help for clinical medical staff, and alleviate the pressure of the current shortage of medical resources.

It is worth mentioning that in addition to auxiliary diagnosis, Alibaba cloud, Baidu and other Internet enterprises have recently announced the opening of AI computing power to help drug research and development in the treatment of new coronavirus pneumonia. However, although AI has achieved initial results in medical assistance, the problems AI medical now faces are the same as all new drugs. A large number of clinical experimental data are needed for AI medical system to be applied to more institutions. Without the support of data, AIs help to the medical system is still very limited. However, we can see that 5g and AI have more practical applications in this anti epidemic campaign, which is a good start for the upcoming 5g + AI intelligent communication.
