Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0034] Such as figure 1 Shown, the present invention is concretely realized as follows:

[0035] 1. Composition of chemical hazard assimilation prediction system

[0036] The system is divided into 6 modules, which are release information estimation module, meteorological field module, concentration prediction module, observation data processing module, data assimilation module, result analysis and display module. The chemical hazard assimilation system structure is as follows: figure 2 shown.

[0037] Release information estimation module: used to provide the initial source strength information of aerosol cloud clusters for prediction models. If the release information data can be obtained through reliable information, it can be directly substituted into other modules for prediction; if the release source item information cannot be obtained accur...

A four-dimensional variation method is adopted to assimilate hazard monitoring data, six systems includingsource intensity estimation, meteorological field construction, concentration prediction, observation data processing, data assimilation, result analysis and display form a module, and the precisionand speed of chemical hazard prediction are improved.

Description

technical field [0001] The invention relates to a chemical hazard assimilation system and the technical field of chemical hazard information system. Background technique [0002] In the emergency treatment of chemical explosion accidents, how to accurately describe the spatio-temporal law of the concentration of hazardous substances after diffusion based on the limited information available is the key to the next step of emergency decision-making. The prediction and evaluation of the chemical explosion diffusion concentration field play a vital role in the follow-up emergency rescue and deployment decision-making. Only by accurately grasping the temporal and spatial distribution of the concentration of hazardous substances and accurately delineating the poisonous area can the degree of harm be minimized , to improve the effect of emergency rescue, and accurately obtaining the initial value information of the concentration diffusion field of chemical hazards is the key to cha...
