列车车厢空气质量环境智能检测和调控系统
Intelligent Detection and Control System for Air Quality Environment in Train Carriages

随着我国高速铁路的发展，乘客对乘坐舒适性的关注度越来越高。由于现有列车车厢对空气质量检测和自动控制系统的应用不够广泛，无法对列车空气质量变化做出及时的响应，导致列车内空气质量不够好，游客乘坐体验感较差，因此本文进行列车车厢空气质量环境智能检测和调控系统的研究。主要基于STM32单片机为系统核心控制系统智能检测与调控，首先检测包括AM2302 (DHT11)检测温湿度，使用5516光敏电阻测量光照，MG812检测二氧化碳气体。然后根据检测结果，考虑节能，在正常情况选择智能控制风道系统来进行改善空气质量，在高压或隧道情况通过调控空气净化系统来改善空气质量。
With the development of high-speed railways in China, passengers are paying increasing attention to ride comfort. Due to the limited application of air quality detection and automatic control systems in existing train carriages, timely responses to changes in train air quality cannot be made, resulting in poor air quality inside the train and poor passenger experience. Therefore, this article conducts research on an intelligent detection and control system for air quality environment in train carriages. Mainly based on the STM32 microcontroller as the core control system for intelligent detection and regulation, the first detection includes AM2302 (DHT11) to detect temperature and humidity, using a 5516 photoresistor to measure illumination, and MG812 to detect carbon dioxide gas. Then, based on the detection results, energy conservation should be considered, and an intelligent control air duct system should be chosen to improve air quality under normal conditions. In high-pressure or tunnel conditions, adjust the air purification system to improve air quality.
