基于STM32的地铁列车环境参数监测系统设计OA

Owing to high passenger density and a semi-enclosed operating environment,the coupled thermal-humidity field and particulate matter(PM)concentration within metro compartments critically affect passenger comfort.To detect environmental parameters in real-time,a detection node for environmental parameters is developed,employing an STM32 microcontroller as the core,an ATS-HT101 temperature-humidity sensor,an ATS-JGFC01 PM sensor,and an Air-Sniffing multi-gas sensor as detection units,with an LCD for local display.Each node is connected via its CAN interface to establish a distributed train environmental detection system.This paper details the overall system architecture,elaborates on the software and hardware design and implementation of the detection node.Experimental validation confirms reliable node operation and accurate environmental parameter acquisition,laying a solid foundation for future intelligent train-environment management.
