beijing news (reporter zhang lu) on september 6, the beijing municipal committee of the chinese people's political consultative conference held a special consultation meeting. beijing municipal committee of the chinese people's political consultative conference members and experts put forward suggestions on "strengthening the construction of smart emergency response and improving the city's emergency management capabilities." the reporter learned from the meeting that relevant departments in beijing have promoted the full coverage of satellite phones in 7 mountainous areas (941 mountainous villages).
"strengthen smart emergency construction and improve urban emergency management capabilities" is this year's consultative supervision topic. starting from march, the beijing cppcc proposal committee took the lead in establishing a research group to conduct supervision and research. the research group believes that beijing's monitoring and perception system needs to be further strengthened, emergency data barriers need to be further opened, and emergency communication networks need to be further upgraded. it is recommended to improve full-domain perception and create a precise and intelligent monitoring and early warning system; strengthen data sharing and consolidate the open and integrated data foundation; focus on the combination of construction and use, build a large model of urban emergency, create a smart "emergency brain", and support various intelligent applications; promote network integration and build an integrated air-ground emergency communication system. it is reported that, based on the recommendations of the research group, relevant departments in beijing have promoted the full coverage of satellite phones in 7 mountainous areas (941 mountain villages).
in recent years, with the intensification of global climate change and the acceleration of urbanization, extreme weather events have occurred frequently, and the risk of urban flood disasters has increased significantly. at the meeting, sun liang, member of the shunyi district cppcc and general manager of the smart water business department of china communications information technology group co., ltd., suggested strengthening the construction of the "three lines of defense" for rain monitoring and forecasting, integrating multi-source data such as satellite remote sensing, digital elevation model (dem), and site monitoring, and using artificial intelligence such as deep neural network technologies to identify the hydrological spatiotemporal correlation between stations upstream and downstream of the basin, and improve the accuracy and predictability of flood forecasting. use remote sensing, video, sensing and other methods to achieve holographic perception of water conservancy project construction areas. fully integrate computer vision technology to identify potential safety hazards such as construction sites, water accumulation in camps, and engineering leakage; through the sparse perception method of neural networks, use as few monitoring sample points as possible to estimate the overall mechanical change trend of slopes, etc., and discover landslide risks in advance.
many members also mentioned the importance of technological assistance. bai lin, member of the beijing cppcc and vice president of the school of cyberspace security at the beijing university of aeronautics and astronautics, suggested promoting the use of ai big models to empower joint prediction and early warning. using ai big models, we can integrate multi-disaster data, build disaster chain models, analyze the coupling effects between disasters, and conduct comprehensive predictions based on the laws of spatiotemporal evolution, and establish a collaborative early warning platform across professional fields.
rescue teams and grassroots communities are the frontline for rapid response and emergency rescue. zhang hui, an expert of the research team, a member of the human resources, environment and construction committee of the municipal committee of the revolutionary committee of the chinese kuomintang, and deputy director of the institute of public security of tsinghua university, suggested improving the service support capabilities of frontline rescue teams, including social volunteer teams. track the location and status of each person in the frontline rescue team, and equip them with environmental monitoring and communication equipment to provide early warning when problems arise, so as to quickly reinforce or rescue. build a large model for frontline rescue, monitor and dispatch all combat teams, equip them with drones, robots, and live broadcast systems, and improve the ability to obtain disaster data on site.
"on the basis of improving the urban risk perception network and promoting data sharing among departments, citizens are encouraged to take the initiative to report emergency information, so that each citizen's mobile terminal can become a risk perception monitoring point." huang xiaobin, member of the municipal cppcc, vice chairman of the beijing federation of industry and commerce, chairman of beijing times lingyu technology co., ltd., and convener of the smart city committee studio, suggested that through policy support and financial subsidies, enterprises should be guided to actively participate in data sharing and become data sources in key areas such as safe production and hazardous chemicals management. the scope and intensity of opening public data to enterprises should be increased to release the technological innovation capabilities of enterprises and empower the digital level of emergency business.
