China News Service, Beijing, April 10 (Chen Hang) AI image-assisted diagnostic products, AI identification temperature measurement equipment, new reusable masks ... Before the epidemic, Beijing, as a national scientific and technological innovation center, fully exerts its scientific research advantages to speed up epidemic prevention Control scientific research, and go all out to provide scientific and technological support for "stopping" the epidemic.
Xu Xinchao, deputy director of the Beijing Municipal Science and Technology Commission, mentioned the above at the press conference on the 10th.
AI helps diagnosis and treatment, temperature measurement
Beijing has developed AI imaging-assisted diagnosis products to improve the rate and level of diagnosis and treatment. According to Xu Xinchao, it actively promotes the research and development of AI-assisted diagnostic products, supports companies such as Proposal Technology, Shukun Technology, Ande Medical Intelligence, etc., and has launched a number of new coronary pneumonia AI image-assisted diagnostic systems and new products to provide doctors with early warning, Quick screening, differential diagnosis, disease progression analysis and other functions have been launched in Beijing, Wuhan and other places.
In response to the characteristics of large crowd size, high density, and fast flow in public places, the Beijing Science and Technology Commission urgently organized the Eleventh Institute of China Electronics Technology Group, Geling Shentong Company and other units to initiate joint emergency research around temperature measurement needs. Developed non-contact intelligent temperature measurement equipment in just 8 days, and has infrared and visible light dual light fusion, intelligent face recognition, rapid body temperature measurement, body surface temperature detection conversion, abnormal temperature alarm, data network analysis, The platform displays monitoring and other functions to facilitate the subsequent search and management of persons with abnormal body temperature. At present, it has been "three stations and one station" in Beijing railway stations, subway stations, long-distance bus stations, airports, etc., Wumei, supermarkets, etc. Supermarkets, and science and technology parks, enterprises and other units have been put into use, with a total of more than 1,600 units, playing an active role in orderly resumption of production and production. At the same time, the Municipal Science and Technology Commission, the Market Supervision Bureau, the Municipal Metrology Institute and other relevant departments standardize the temperature measurement equipment use standards, actively carry out measurement testing, and improve the efficiency of temperature measurement equipment use.
Xu Xinchao said that he organized the Beijing Microchip Research Institute to develop wearable smart thermometers based on the monitoring needs of key people such as home isolation and catering. Compared with ordinary thermometers, the thermometer has the functions of high detection accuracy, continuous monitoring of body temperature during wearing, network analysis of monitoring data, platform display monitoring, abnormal temperature alarm, three-level stratification management and other functions. At present, more than 11,700 units have been put into use throughout the city, and more than 90,000 new units have been issued recently, which will increase the promotion and application of high-touch populations in industries such as catering, beauty salons, and housekeeping.
AI algorithm improves vaccine development efficiency
Beijing promotes the first large-scale application of AI algorithms and computing power to the research and application of viral infectious diseases. It has greatly improved research and development of medical devices and drugs such as viral gene sequencing, vaccine / drug development, protein screening, etc. In view of the research efficiency and the speed of application, the intelligent research of viral infectious diseases has begun to take shape.
The Linear Fold algorithm has provided technical assistance to more than 100 new coronavirus research and development institutions worldwide. As the first major speedup in the field of RNA structure prediction in 40 years, the Linear Fold algorithm makes it possible to predict RNA structure of whole sequences and whole genomes, and can shorten the genome-wide secondary structure prediction of this new coronavirus from 55 minutes to 27 The speed is increased by 120 times in seconds, and the opening and sharing of the algorithm will help to improve the prediction speed of the RNA structure of the new coronavirus.
Development of new reusable masks
Focusing on the demand for high-quality masks in epidemic prevention and control, Beijing organized Beijing Fashion Holdings Group, Beijing University of Chemical Technology and other units to develop new masks and reusable civilian masks. In response to the problem of version discomfort in the development of the Fashion Holdings Group, Beijing facial recognition companies were organized to provide 9 sets of typical three-dimensional facial structures through the analysis of Chinese facial big data; aiming at optimizing the filtering effect of masks, insufficient supply of raw materials and parts, etc. , Organize Beijing University of Chemical Technology, Sinochem Beijing Rubber Institute, Beiqi Hainachuan Company and other units to carry out technical research, improve the filtration efficiency of masks through process optimization, and ensure the supply of materials. At the same time, starting from the formula and process of the core functional material of the mask, Beijing University of Chemical Technology was organized to develop a new type of electret polypropylene material with independent intellectual property rights. The developed 25-gram remelted spray cloth has a filtration efficiency of 89.6%, which is better than other similar domestic products. The product can withstand 5 times hot water immersion disinfection.
Xu Xinchao mentioned that organizing the city labor insurance office, building a mask detection platform, and choosing masks for the mainstream market applications, choosing high-temperature wet steaming, high-temperature dry steaming, electric oven baking, hot water immersion and other disinfection methods for home convenience and simple operation. A batch of disposable masks was tested and analyzed for protection performance, virus inactivation, effect of wearing time, and morphological characterization of electron microscope after multiple disinfection, forming a safe and convenient disposable mask reuse operation specification suitable for non-medical environment. At the same time, using the established mask testing platform, we provide the highest priority testing service and technical consultation for new reusable masks developed by fashion holding and other units.
Up to now, the platform has provided testing services for more than 1,500 mask samples and related core functional materials submitted by three mask development units. (Finish)
