停车场机动车尾气监测系统设计

Design of Vehicle Exhaust Monitoring System in Car Parks

为解决停车场机动车尾气堆积问题,设计一种基于STM32的机动车尾气监控系统,监控停车场的机动车尾气浓度.系统以STM32微处理器为核心,采用多个传感器采集停车场内的CO、CO_2、NO、NO_2等有毒有害气体浓度,经MCU处理,通过SRWF-1021无线模块发送给尾气浓度采集总节点,总节点将数据转发给上位机,上位机根据收到的数据判断是否开启风机系统,从而保证停车场机动车尾气浓度维持在安全范围.

In order to solve the problem of gas accumulation from vehicle exhaust in car parks,agas monitoring system is designed based on STM32 to monitor vehicle exhaust gas concentration.This system uses the STM32 microprocessor as the core,and multiple sensors to collect the concentration of CO,CO_2,NO,NO_2 and other toxic and harmful gases in the car park.The collected gas concentration is processed by the MCU and is then sent to the center gathering node for the exhaust gas concentration through the SRWF-1021 wireless module.The center node transmits the data to the host computer,which according to the data received determines whether to turn on the ventilation system to ensure the exhaust gas concentration in the car park maintained within a safe range.
