Abstract

The invention provides a real-time situation model and visual fusion decision method which is applicable to rescue for leakage accidents of hazardous chemical substances. The method comprises the following steps: field environment data of a hazardous chemical substance accident is collected, fluidized and sent to a command center; the command center de-fluidizes the received data to restore the field environment data; the leakage rate of source intensity is calculated; a real-time situation is simulated according to the leakage rate of source intensity, the field environment data and accident terrain data; concentration points of grid computing are used to carry out triangulation difference calculation on the result of situation simulation, the spread movement track of different dangerous areas is rendered according to color gradient, and the maximum accident influence scope is predicted; and the population density in the maximum accident influence scope is calculated, and an optimal rescue evacuation path is evaluated out. The disadvantages of a static data model and the real-time transmission problem caused by shortage of bandwidth resources are overcome, and the accuracy, effectiveness and level of intelligence of emergency rescue are improved effectively.

Description

technical field [0001] The invention relates to an emergency treatment technology for sudden accidents, in particular to a decision-making method and system based on flow parameter-based real-time situation model and visualization fusion. Background technique [0002] Many process industries use or produce some hazardous chemicals that are harmful to the human body during the production process, especially toxic and harmful gases or liquids. Once the leakage of hazardous chemicals occurs, the leaked hazardous chemicals may cause serious harm to humans within a certain range. When a hazardous chemical leakage accident occurs, the leaked substance and the approximate location of the leak can be relatively easily determined, but it is difficult to obtain the leakage rate or leakage rate of the hazardous gas on site. It is an important part of the accident emergency response process to predict the diffusion trend and influence range of hazardous chemicals with limited informati...
