A new generation of information technology supports service war “epidemic” to resume production

In the tense battle against the epidemic, residents in Beijing, Hubei, Wuhan, Anhui Hefei, Jilin Changchun and other provinces and cities received similar calls in a short period of time. Screening, health education and other work should be coordinated, so that epidemic prevention and control can cover a wider population.

The assistant phone robot can notify 150,000 residents of the epidemic situation in just one hour, cover nearly 2 million phone calls every day, send more than 5 million SMS notifications, record and feedback the content of the calls, and automatically generate statistical reports.

At present, the epidemic prevention and control is still in a critical period, and enterprises are gradually resuming work and production. As one of the representatives of the new generation of information technology, artificial intelligence has many characteristics such as “improving efficiency”, “reducing difficulty” and “strengthening innovation” in epidemic prevention and control, resumption of work, etc. Reproduction has been reflected.

Shorten diagnosis time, artificial intelligence fights on the front line

During the outbreak of the epidemic, many artificial intelligence companies actively participated in the front-line fight against the epidemic, using the advantages of artificial intelligence to conduct medical auxiliary diagnosis, image analysis, and medical guidance, helping front-line doctors to save time and snatch precious time for winning the battle against the epidemic. A large number of intelligent robots have played an important role in reducing the work intensity of front-line medical staff and reducing cross-infection in disinfection, meal delivery, medicine dispensing, remote diagnosis and other work.

How to save diagnosis time has always been the focus of major hospitals. Doctors have subjective differences in grading the severity of COVID-19, and the traditional quantitative assessment method of manually delineating the lesion area is time-consuming, inefficient, and difficult to clinically promote. It takes 1 to 2 hours for mild cases and 3 to 5 hours for severe cases.

The reporter learned through interviews that a special “new member” has appeared beside the doctors on the front line of epidemic prevention in the People’s Hospital of Wuhan University. It can realize the whole process of auxiliary diagnosis before, middle and late stages of the disease, and adopts innovative artificial intelligence for whole lung quantitative analysis. technology, improve the speed and accuracy of diagnosis, and help doctors to quickly detect, quantitatively detect, and evaluate curative effects. This is the intelligent imaging evaluation system for novel coronavirus pneumonia jointly developed by Shanghai Public Health Clinical Center and Yitu Medical. Quantitative analysis.

One CT scan of a case will produce 300 to 400 films, and a single local hospital in Hubei can perform up to 150 CT examinations of suspected patients per day. The heavy workload and the accuracy of the diagnosis of this new disease have put many front-line doctors in a state of high pressure and fatigue. In order to relieve the pressure of front-line doctors as quickly as possible, SenseTime has developed a lung AI intelligent analysis product, which is connected to the medical image reading platform in the mode of cloud service, and quickly supports more than ten front-line hospitals and medical institutions in a remote way. Many hospitals and medical institutions provide AI-assisted analysis for doctors.

“Please wear masks, pay attention to personal hygiene, do not go to crowded places, and if you feel unwell, please seek medical attention in time…” The mobile medical temperature measurement patrol robot with 5G communication technology is in the city station of the First Affiliated Hospital of Zhejiang University School of Medicine The branch is officially applied. With the high-definition video carried by the robot, it is possible to observe the scene without dead ends, and perform precise temperature measurement within 10 meters from the human body by infrared method. For those whose body temperature exceeds the warning value or who do not wear masks, the robot will send out temperature warnings and reminders through audio broadcasts on the spot.

Intelligent monitoring optimizes production to help enterprises resume work and production

In addition to Hubei, the number of newly confirmed cases in many parts of the country has achieved “zero growth” for several days. The resumption of work and production of domestic enterprises is proceeding in an orderly manner, and employees are returning to work one after another. How to quickly monitor the temperature of employees under the premise of correct protection has become the first threshold for employees to return to work.

Some of the initial solutions companies have adopted are thermal imaging cameras to measure employee temperatures. However, large-scale enterprises have a large number of employees and a high density of crowds. Even after long-term work, the thermal imaging camera will produce large errors and cannot meet the standard of 37.3 °C for the prevention and control of the initial screening of suspected patients. Some thermal imaging cameras with lower sensor resolutions are still unable to take pictures at long distances. Pedestrians wearing masks, glasses and hats, as well as bangs covering their foreheads, will interfere with temperature measurement to a certain extent.

These instabilities of thermal imaging cameras are improved by AI technology. It is understood that the SenseTime AI intelligent temperature measurement and screening terminal can meet the working hours of 7 × 24 hours. Through the AI ​​algorithm, the accuracy of thermal imaging temperature measurement technology is controlled at ±0.3 °C without the black body; when there is a black body In the case of temperature, the accuracy can be optimized to close to ±0.1℃, which can better support body temperature screening and assist epidemic prevention and control. “At this stage, AI technology can basically eliminate the interference of bangs, glasses, hats, masks, etc. AI technology can be more applied to the precise prevention and control of the epidemic in the future, and make a contribution to the emergency management of public health events. More contributions.” Yan Junjie, vice president of Shangtang Technology, told reporters.

On the other hand, ensuring the efficient commuting flow of employees is a top priority for enterprises to resume work and production. How to count and analyze multi-source data such as Internet data, urban governance data, public security traffic police data, and urban traffic data is the premise to ensure employee commuting. iFLYTEK launched the “Urban Ultra Brain” platform relying on artificial intelligence technology, which has gathered more than 3 billion pieces of urban data, which can help designated cities quickly collect vehicle data in the city, and intelligently screen out risky vehicles, providing effective solutions for the city’s battle against the epidemic. protection.

In addition to temperature detection and ensuring employee commuting, artificial intelligence is even more useful in actual production management.

“Faced with the pain points such as large demand for personnel and low production efficiency in the process of resuming work and production, enterprises have extensively used artificial intelligence technologies such as intelligent voice, machine learning, and expert systems to reduce the demand for personnel and improve production efficiency.” CCID Think Tank Informatization Song Yingchang, deputy director of the Industrial Internet Research Office of the Software Industry Research Institute, said in an interview with a reporter from China Electronics News.
