Air quality monitoring and evaluating method and system

Abstract

The invention provides an air quality monitoring and evaluating method. The method is based on an air quality evaluation model QOI algorithm, and is used for monitoring and evaluating the environmental quality. The method specifically comprises the following steps: 1) acquiring an actually measured concentration value of each pollutant in the air in real time through a data acquisition module by referring to a graded concentration limit value of each pollutant in the air, correspondingly calculating and obtaining an air quality index IAQI of each pollutant, and transmitting the air quality index IAQI of each pollutant to an environment-friendly intelligent monitoring terminal; 2) according to the IAQI of each pollutant obtained at step 1), selecting the maximum value of the IAQI to determine the AQI of the air quality index, and monitoring the air quality in real time according to the air pollution index through the environment-friendly intelligent monitoring terminal; 3) determining and evaluating the air quality level, the air quality category and the color representing the air quality according to the AQI grading standard.

AI Technical Summary

Problems solved by technology

[0007] Third, the hygienic evaluation method can evaluate from the most fundamental purpose of environmental protection, but there is a certain lag in the reflection of environmental pollution

[0008] Fourth, the ecological evaluation method can comprehensively reflect the degree of pollution impact and understand the accumulation degree of pollution, but it cannot provide an accurate concept of data volume

Biological growth is affected by factors other than its contamination, which can make evaluation difficult

[0009] Fifth, the fuzzy mathematics evaluation method, which evaluates according to the degree of membership, can accurately determine the degree of pollution, but the evaluation results are not intuitive enough for short-term evaluation
