Embodiment Construction

[0047] Such as figure 1 As shown, the specific implementation process of the embodiment of the present invention is as follows:

[0048] Step 1: Multi-point collection of pollution data

[0049] Interior of train carriage including PM 2.5 , PM 10 , CO, NO 2 , SO 2 and O 3 Six kinds of air pollutants and microbial pollution such as bacteria, fungi, and viruses. Microorganisms are closely related to air quality conditions. Generally, the total number of bacterial colonies in the air is positively correlated with the probability of the existence of pathogenic microorganisms (bacteria, fungi, viruses). Therefore, this patent uses the total number of bacterial colonies to measure the pathogenicity of microorganisms . Arrange TS WES-C air pollutant detectors (measure PM 2.5 Concentration, PM 10 concentration, CO concentration, NO 2 Concentration, SO 2 Concentration, O 3 Concentration, real-time detection) and Andersen impact air microbial sampler (to measure the total nu...

Abstract

The invention discloses a train compartment air ventilation adjusting method and system based on microorganisms and a storage medium. A ventilation system is adjusted according to microorganism diffusion between measuring points, and microorganism pollution indexes of areas where passengers are located is reduced. The method has a guiding effect on air quality adjusting of railway trains. A mapping relationship between microbial pollution and atmospheric pollutant concentration is studied, a real-time problem of a microbial detection can be effectively solved, and real-time adjusting of the microbial pollution in train carriages is ensured.

Description

technical field [0001] The invention relates to the field of train environment monitoring, in particular to a microorganism-based method, system and storage medium for air conditioning in train compartments. Background technique [0002] With the continuous development of my country's rail transit industry, the comfort requirements of passenger trains have gradually attracted the attention of the public. Affected by air pressure waves, the train compartment needs to ensure an appropriate internal and external pressure difference when running at high speed. Therefore, high-speed trains usually adopt a sealed car body structure, and all windows cannot be opened. In this case, the treatment of air pollutants inside the cabin is entirely dependent on the ventilation system. Therefore, the quality and regulation strategy of the ventilation system will directly affect the passenger comfort. How to monitor the train environment and adjust the ventilation system accordingly has be...
