Seismologists and information experts jointly discuss the application of earthquake prevention and disaster resistance sensing

in order to 1. First, consider the need to test the pull range of materials, implement the spirit of the expanded meeting of the leading group for earthquake relief work of the Chinese Academy of Sciences, further give play to the advantages of the Chinese Academy of Sciences in talent base, knowledge accumulation and scientific equipment, and give full play to the spirit of inter Institute and interdisciplinary cooperation, On the evening of May 27, the micro system center of the information base of the Chinese Academy of Sciences organized a seminar on the needs and technology of sensing for earthquake prevention and disaster resistance at the Graduate School of the Chinese Academy of Sciences in Beijing, and invited relevant units of the National Seismological Bureau, China Mobile, zihuankou of the Chinese Academy of Sciences, and high-tech port to discuss earthquake prevention and disaster resistance, and discuss the application of sensing in disaster monitoring, secondary disaster prevention, and other fields. More than 20 experts and scholars, including geophysicist Shi Yaolin, academician, researcher Chen Qifu of the Institute of earthquake prediction of the National Seismological Bureau, general manager Zhou Jianming of the Technology Department of China Mobile Group, deputy director Liu Haitao of the Shanghai Institute of Microsystems, and the five hundred person program in Geoscience and sensing, participated in the seminar

Liu Haitao, deputy director of the Institute of Microsystems of the Chinese Academy of Sciences, combined with the results of the cooperative research projects between China Mobile and the Chinese Academy of Sciences, proposed on behalf of the Chinese Academy of Sciences team the idea of combining more than 300000 mobile communication base stations and sensors of China Mobile to build a national earthquake and disaster resistant sensing infrastructure for disaster monitoring and secondary disaster prevention, which can greatly improve the density of earthquake monitoring points in China; It is proposed that the combination of sensor network and mobile base station can form a two-stage high intelligent multi parameter and multi-dimensional filter array, which can make up for the low test signal-to-noise ratio of a single sensor. In response to this assumption, seismologists such as academician Shi and researcher Chen Qifu put forward relevant suggestions and expectations from the perspective of seismic and geophysical monitoring needs. The sensing experts present at the meeting also put forward a variety of possible solutions. Experts at the meeting believed that the combination of sensing and mobile technology can be applied to the data acquisition and rapid transmission of natural disaster monitoring and early warning such as earthquakes and landslides

academician Shi Yaolin believes that the interdisciplinary cooperation between geophysicists and sensing experts is a very useful work. If sensing can be used to collect relevant signals of interest to seismological research, such as long-period seismic waves, it will be very helpful to study the crustal structure. In particular, if stations (i.e. sensor arrays) are deployed under a large number of mobile communication base stations, the amount of data obtained will be large. Its working principle is that the electromechanical control by the servo system is larger than the amount of data monitored by traditional methods. This may be a revolutionary breakthrough in the basic work of seismology, which is also a contribution to geophysics, just like ensuring wastewater, exhaust gas A huge CT fluoroscopy equipment was designed for the structural study of the 100% target rate of the comprehensive emission of pollutants. The urgent task is to test and verify whether our sensors can detect and which frequency range of seismic signals

researcher Chen Qifu suggested to find a test site (such as the Sichuan Yunnan test site) or a province, seismic departments, universities, research institutes, operators to do exploratory experiments, including data needs, acquisition methods, rapid data transmission and analysis

general manager zhoujianming said that China Mobile will support the work of the National Seismological Bureau and the Chinese Academy of Sciences, mobilize resources, and increase the output of other small and medium-sized enterprises to varying degrees, both for earthquake relief services. At the same time, it is proposed that in order to improve the utilization rate of national earthquake and disaster prevention sensing infrastructure combining mobile communication and sensing, it should also serve the needs of forest fire prevention and be applied to comprehensive natural disaster monitoring

combining a large number of mobile communication base stations to build a national sensor integrated natural disaster monitoring system, how to solve or improve the high signal-to-noise ratio ability of a single sensor, how to solve the low-cost ultra-low frequency seismic signal testing and other problems are very worth discussing, which requires the joint efforts of geophysicists and sensing experts. The joint efforts of the National Seismological Bureau, the national development and Reform Commission, the Ministry of industrial information technology, the Chinese Academy of Sciences and operators will lay a solid foundation for breakthroughs in earthquake prediction, disaster monitoring, secondary disaster prevention and control and other fields in China

the units participating in the discussion are: Institute of earthquake prediction, China Earthquake Administration, Technology Department of China Mobile, microsystem center of Chinese Academy of Sciences, Graduate School of Chinese Academy of Sciences (School of Earth Sciences, School of information, School of computing and communication), Institute of remote sensing, Shanghai Institute of microsystem, Institute of acoustics, Institute of electronics, Institute of computing, etc
