Chemical industry park environment pollution detection method and device based on multi-source remote sensing data

Abstract

The invention provides a chemical industry park environmental pollution detection method and device based on multi-source remote sensing data. The method mainly includes the steps that the multi-source remote sensing data of a detection region in a chemical industry park environment are obtained through a sensor or an earth observation satellite or others; pollution information is extracted from the multi-source remote sensing data, and whether a pollution accident happens on the detection region or not is judged according to the numerical value of the extracted pollution information and a preset pollutant judgment threshold value; according to a multi-source remote sensing image of the detection region where the pollution accident has already happened, smog floating analysis is performed on the detection region to generate a pollution accident substance diffusion model, and the position of an accident source is obtained according to the pollution accident substance diffusion model. The portable chemical industry park environmental pollution detection device integrates multi-source remote sensing data collection, pollution accident and accident source position judging, emergency processing and other functions, and rapidness, efficiency and standardization of environmental pollution sudden accident emergency rescue in a dangerous chemical industry park are achieved.

Description

technical field [0001] The invention relates to the technical field of pollution detection, in particular to a method and device for detecting environmental pollution in a chemical industry park based on multi-source remote sensing data. Background technique [0002] Public safety is the cornerstone of national security and social stability. Chemical safety is an important part of public safety and the core of production safety. The safety of hazardous chemicals is a matter of great concern to all countries in the world, especially the occurrence of some serious accidents has made countries pay more and more attention to the safety of hazardous chemicals. For example, in 1984, a malignant poisoning accident of methyl isocyanate leakage occurred in a pesticide factory in the suburbs of Bhopal, India. More than 2,500 people were poisoned and died, and more than 200,000 people were poisoned and injured. Most of them were blind and disabled, and 670,000 people were injured. Aff...

Problems solved by technology

[0004] At present, the portable detection equipment used for monitoring the gas concentration of hazardous chemicals in the prior art has relatively single functions, some can only perform gas detection, and some can only conduct emergency system application command, and various equipment cannot be automatically realized Effective associations, difficult to work together

After the accident, it is impossible to obtain relevant information of the accident site in a timely and accurate manner, and it is impossible to accurately determine the location of the accident source, which seriously affects the smooth development of emergency rescue work and easily causes major property losses and casualties.
