Vice Mayor Wen first of all, on behalf of the municipal Party Committee and the municipal government, welcomed the arrival of experts and scholars, and said that in recent years, Wuzhou is working hard to promote the landing of scientific and technological achievements, contributing to the construction of safe China Wuzhou strength, and finally wish this conference a complete success.
On behalf of Nanning Customs, Deputy Commissioner Shi extended congratulations on the convening of the congress. Nanning Customs has a major task to protect the security of the southern border, and he expressed the hope that the leading experts can put forward valuable opinions and suggestions for the biosesafety protection work at the port through the seminar.
The conference invited Academician Fan Weicheng to deliver a report on "National Security Development under the New Security Pattern". Academician Fan pointed out that to maintain national security under the new situation, we must speed up the construction of a new security pattern. The report discusses the development path of national security under the new security pattern from three aspects: the connotation structure of the new security pattern, the construction of national security disciplines, and the scientific and technological support of national security development. The "new" of the new security pattern is mainly reflected in the dimensions of new positioning, new judgment, new deployment and new thinking. Under the new security pattern, strengthening the construction of national security disciplines is a major requirement for promoting high-level and high-quality development of national security undertakings. The development of national security cannot be achieved without solid scientific and technological support. We must make full use of high-level emerging technologies to strongly support and ensure security in key national areas.
Mr. Chi Haipeng reported on "Photon directed Precision Microbial identification (PPMI) technology and optical elimination technology", pointing out that the drawbacks of traditional detection methods of viruses in the air are: the detection time is too long, and can not meet the needs of some scenarioses. The "photon directed Precision Microbial Identification (PPMI) technology" independently developed by Dana Technology can detect pathogenic microorganisms in the air within 3-5 minutes, which is about 36-60 times faster than traditional methods. This technology has the characteristics of full automation without human interference, including automatic sampling and processing, automatic detection, automatic transmission of detection data, etc. At the same time, the products developed based on this technology have the characteristics of small size (about 300*240*320mm), low energy consumption (about 60W), and can be applied to many scenarioses with rapid detection of pathogenic microorganisms in the air.
Mr. Chi Haipeng further explained that PPMI technology is based on the Raman spectroscopy detection technology of specifically labeled nanomaterials probe, and integrates photon directed enrichment technology and artificial intelligence spectral neural network technology to achieve rapid and accurate identification of pathogenic viruses and microorganisms in the air.
At present, DYNA commissioned the Institute of Biology of the Chinese Academy of Metrology Sciences to verify the effectiveness of optical rapid detection of virus equipment. From the verification data obtained so far, its detection is close to or better than the digital PCR instrument. Experimental data show that the optical rapid virus detection equipment independently developed by DYNA can be used to detect influenza A H1N1, H3N2, new coronavirus, and several common bacteria. The lower limit of detection was below 100copies/L, and the specificity (true negative rate) and sensitivity (true positive rate) were both above 90%.
The deep ultraviolet laser eliminator independently developed by DYNA combines the laser optical path design principle with deep ultraviolet light to greatly improve the irradiation intensity in the eliminator cavity, thus effectively improving the elimination efficiency of viruses and bacteria in the air. DYNA commissioned the Chinese Academy of Metrology to conduct testing, and the experimental process was simulated in strict accordance with the real scene, and the unique aerosol detection technology of the Chinese Academy of Metrology was used for detection and verification, and the virus was simulated with fake novel coronavirus. After repeated testing, the validity verification report of the air eliminator was obtained. The elimination efficiency of the novel coronavirus in the air was 98.2%, and the elimination efficiency of the bacteria in the air was 99.9%. The ozone test concluded that no ozone was produced. The test result of UV leakage of the equipment is < 1µw/cm2(national standard requirements < 5µw/cm2), meeting safety requirements.
At present, DYNA has produced 4 models of air eliminator, including: 400, 240, 126, 100:
The project of "Ping An China and Social Governance Engineering Technology Development Strategy Research in the Next 20 Years", co-chaired by Academician Fan Weicheng and Academician Zhang Jun, is one of the interdisciplinary projects in the major strategic research project group "China Engineering Science and Technology Development Strategy Research Consulting Project in the Next 20 Years" jointly established by the Chinese Academy of Engineering and the National Natural Science Foundation of China. The project focuses on China's typical problems in natural disasters, accidents, epidemic prevention and control, social security and other aspects, and attaches importance to the urgent scientific and technological needs of the national emergency management system and the comprehensive social governance system.
