[0002]
The existing indoor air quality evaluation standards in my country use pollution factors as indicators for evaluating indoor air quality in isolation, and cannot comprehensively reflect the level of indoor air quality. Therefore, in recent years, relevant scholars have proposed to establish a comprehensive evaluation model for air quality.
However, a unified and comprehensive comprehensive evaluation model has not yet been established. The indoor air quality comprehensive evaluation model proposed by the research community is mainly based on the following three methods, but all have their limitations:
[0003]
Comprehensive index evaluation model: The most representative comprehensive index evaluation model is the Shen’s model proposed by Shen Jinming. The Shen’s model takes into account both the highest sub-index and the average sub-index, and can roughly evaluate the level of major indoor pollutants and indoor air. The level of quality; however, the relative importance of each factor has not been carefully divided, and in some cases, this indicator cannot be effectively judged
[0004]
Fuzzy comprehensive evaluation model: The fuzzy comprehensive evaluation model needs to establish a membership function for each level, the process is complicated, and the calculation method of choosing large and small is easy to lose more information, and loses the original meaning of comprehensive evaluation
[0005]
Gray comprehensive evaluation model: The gray comprehensive evaluation model can reflect the difference in air quality between samples at the same level, and the evaluation results are intuitive and reliable, but the correlation matrix of indoor air quality evaluation has a large amount of information and the calculation process is complicated

Embodiment Construction
[0031] The present invention will be further described in detail below.
[0032] The air quality detection method based on the improved analytic hierarchy process provided by the invention comprises the following steps:
[0033] (1) Select each evaluation factor in the judgment matrix
[0034] Since it does not meet the actual engineering requirements to include all known indoor air pollutants in the health evaluation indicators, the present invention combines the hazards and action mechanisms of pollutants with the specific national conditions of our country, and selects HCHO when evaluating the indoor air quality of built houses. , CO, CO 2 , NO 2 , SO 2 , PM 10 As an evaluation factor of comprehensive index of health.
[0035] (2) Determine the evaluation level in the judgment matrix
[0036] The level of indoor air quality and health are related to the degree of influence from environmental pollution. The present invention divides it into four grades: clean, unpollu...

The invention discloses an indoor air quality evaluation method based on improved analytic hierarchy process, which comprises the following steps: selecting indoor air quality evaluation factors, determining evaluation grades, determining relative weights of the evaluation factors, establishing an air quality comprehensive evaluation index regression equation, and optimizing an air quality comprehensive evaluation index prediction model based on a multivariate linear fitting method. An example detects an air quality comprehensive evaluation index prediction model. Compared with the prior art, the method provided by the invention corrects and optimizes the relative weight of the evaluation factor based on the improved analytic hierarchy process in combination with a multivariate linear fitting idea, and compared with a currently proposed prediction model, the calculation form is simpler, and the evaluation result is more accurate; and the prediction model not only can evaluate the air quality grade, but also can sort the air quality. The problem that an existing prediction model can only evaluate the air quality grade or can only sort the air quality is solved.
