Abstract

The invention provides a real-time weather data-based evacuation method during the occurrence of a dangerous chemical leakage accident. According to the invention, a Gaussian model and a slab model for the leakage of dangerous chemicals are established firstly. After that, the models for the leakage of dangerous chemicals are corrected based on real-time weather data and sensor data, and then a protection target inside the area of influence and evacuation points around the area of influence are calculated. In combination with the existing road network topological relation, a plurality of evacuation paths from the protection target to the evacuation points are programmed. Finally, according to the real-time wind direction, one evacuation path is selected. According to the invention, by adopting the real-time weather data-based evacuation method during the occurrence of the dangerous chemical leakage accident, the capability of handling with and rescuing the emergency accident of dangerous chemicals is effectively improved, and the damage of the leakage accident of dangerous chemicals to the loss of life and personal injury is greatly reduced. Meanwhile, the method is fast in reaction and high in efficiency.

Description

technical field [0001] The invention relates to a path planning method for evacuation, in particular to an evacuation method for hazardous chemical leakage accidents based on real-time weather information. Background technique [0002] With the rapid development of national economic construction, the types of hazardous chemicals used as raw materials, intermediates and products of chemical production are increasing, and the leakage accidents of hazardous chemicals in the process of production, operation, storage, transportation and use are also increasing . Due to the complex situation of chemical disaster accidents, wide-ranging impact and easy to cause environmental pollution, it is particularly important to correctly adopt corresponding evacuation methods. [0003] The application number is 200910115304.1, and the title of the invention is "Integrated Display Method of Hazardous Chemical Leakage Diffusion Model and GIS", which discloses an integrated display method of ha...
