Chemical hazard prediction precaution and control system

Abstract

The invention has the design principle that prediction wind field and turbulence provide basic meteorological information for a prediction precaution system by a meteorology numerical value forecasting system; the prediction precaution system predicts chemical hazard by respectively aiming at a protected target or an accident source; according to the hazard prediction result and a hazard index system, the spatial and temporal distribution of the chemical hazard precaution information is determined; the prediction precaution system is integrated with GIS by a data conversion engine to build a prediction precaution optimal control application system based on the GIS platform; and the optimal control scheme can be determined according to the precaution information to effectively control chemical hazard. The system is suitable for the requirements on the complex environment of battlefields and emergency response fields, and can satisfy the requirements on timeliness, accuracy and intuitionism of chemical hazard prediction precaution and control.

Description

technical field [0001] The invention relates to a chemical hazard prediction, early warning and control system, which belongs to the technical field of chemical hazard prevention and control. Background technique [0002] With the entry into force of the "Convention on the Prohibition of Chemical Weapons", the possibility of direct use of chemical weapons in war decreases, but the possibility of causing chemical hazards by attacking chemical facilities in war increases, such as NATO's attack on Yugoslav Pancevo in the Kosovo War The consequences and impact of petrochemical facilities are no less than the direct use of chemical weapons; moreover, there are still a large number of chemical weapons that have not been destroyed, and the threat of chemical warfare still exists. In addition, as the situation of chemical terrorist attacks becomes more and more serious, the forms of chemical terrorism diversify. For example, Japan's "Tokyo Subway Sarin Incident" shocked the world, a...

Problems solved by technology

[0004] Prediction, early warning and optimal control of chemical hazards involve multiple disciplines and professional fields. It is necessary to build a technical platform to meet the complexity of the underlying surface of the battlefield and emergency response site, the randomness of the location, the timeliness of decision-making and the intuitiveness of command The following main problems currently exist: (1) The meteorological field of the battlefield and emergency response site is complex and changeable, and the numerical forecast of the meteorological field takes a long time. The current technical level cannot meet the complex underlying requirements of the battlefield and emergency response site. (2) For emergency prediction and early warning of chemical hazards after the incident, existing methods cannot meet the needs of operations, training and emergency response; (3) Mobile risk sources and There is no relevant mature technology for real-time emergency prediction, early warning and control of chemical hazards from multiple fixed risk sources; (4) How to provide the optimal emergency control plan in real time to minimize chemical hazards in combat or emergency rescue? There is no mature method; (5) There is no practical system platform for how the simulation results of emergency prediction, early warning and control can intelligently provide technical support for emergency command and decision-making in real time

[0005] Regarding the above problems, although there are some relevant researches at home and abroad, there are no systematic and practical results, especially the research on real-time emergency prediction, early warning and optimal control of mobile risk sources and multiple fixed risk sources is almost blank
