Chemical emergencies occur frequently, causing many casualties and property losses, and arousing widespread concern in society. "Key Technologies and Applications for Emergency Response and Guarantee of Hazardous Chemical Accidents in Chemical Clusters" is based on the "Emergency Response Law of the People's Republic of China" and based on the "State Administration of Safety Supervision on Issuing Safety Technology& ldquo; Four batches& rdquo; Notice on Project Management Measures (Safety Supervision General Technology (2014) No. 128) and the General Office of the State Council "Opinions on Accelerating the Development of Emergency Industry"(Guo Ban Fa [2014] No. 63) and the Comprehensive Management Plan for Hazardous Chemical Safety (Guo Ban Fa [2016] No. 88) In order to guide, we have broken through the industry bottleneck of real-time interconnection and dynamic prediction of on-site situation in the safety emergency response of hazardous chemical accidents, and proposed a new model of dynamic proactive response and guarantee to provide accident prediction and disposal. Technical means to solve the technical problems that are difficult to integrate multi-disciplinary and the methodological construction problems of new complex emergency events, and provide new ways for the application and practice of the Internet of Things and artificial intelligence. Promote the transformation of methods and methods in the field of production safety. Its scientific and technological progress lies in the adoption of independent innovative technologies: a near-earth fluid prediction technology is constructed based on the combination of atmospheric fluid plume prediction models and GIS terrain matching technology, and the model calculation and analysis are seamlessly integrated with the information system; Based on rapid deployment, multi-modal optimization The idea of the network develops a service sharing rapid reconstruction technology that realizes on-site information interconnection without relying on the public network to ensure the reliable collection and effective transmission of emergency on-site information; Based on the integrated application of active response and artificial intelligence, it realizes visual dynamic scientific decision-making at emergency scenes. This project was recommended because of its urgent and authentic needs, obvious innovation, and completely independent intellectual property rights. It is a comprehensive innovation and successful practice of cross-disciplinary integration, scientific and technological means, application models, and management concepts. The project results have won key support from Shanghai City's strategic emerging industries and the former State Administration of Work Safety (now the Ministry of Emergency Management) ldquo; four batches of key recommendations from the industry. Innovation points: 1. From the perspective of emergency technical support, it took the lead in proposing the scientific problem of perception and decision-making in which information flow-business flow and the flow evolution laws of disaster factors are correlated and coupled, which is conducive to rapid information response and instant perception;2. Interconnection based on flow information and Innovative theories and methods for scientific decision-making. Original research results have been obtained in the research on interconnection and scientific decision-making architecture based on flow information, and a decision-making architecture based on the organic combination of hierarchical functional requirements and cross-network and cross-domain sharing processing has been designed. The research results are for the establishment of an effective peacetime and wartime emergency response system lays the foundation;3. Innovation in emergency response models for hazardous chemicals accidents. Based on the optimized deployment and design of fixed monitoring and mobile emergency systems, active sensing strategies are combined with artificial intelligence and other technologies to realize innovation in risk prevention and control active response model of on-site sensing, real-time interconnection and dynamic analysis and calculation, and improve the effectiveness of Incident Response Service;4. Innovation in the integration method of rapid on-site emergency deployment and data interconnection. The sensing network and transmission network at the hazardous chemicals accident site failed under extreme conditions. This project uses on-site service ad hoc network technology to quickly deploy and build an on-site sensing network. It does not rely on inherent transmission equipment and realizes heterogeneous network data through key data exchange technologies. Rapid access and integration to improve the real-time nature of emergency information interconnection;5. Technological innovation in visual dynamic science to assist decision-making. Based on the real-time situation model of flow parameters and visual fusion decision-making technology, we solve the problems of too long model analysis and calculation time and low accuracy, realize visual control of dynamic situations, and improve the scientificity of emergency dynamic auxiliary decision-making. According to the novelty search and demonstration of the Shanghai Science and Technology Novelty Search Consulting Center of China Academy of Sciences, the key technologies and applications for proactive emergency response and guarantee of hazardous chemical accidents in the project's chemical industry cluster are novel and have reached the international advanced level as a whole.
