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 vehicle exhaust accumulation problem in parking lot, a kind of vehicle exhaust monitoring system based on STM32 is designed to monitor the concentration of vehicle exhaust in the parking lot.The system uses STM32 microprocessor as the core, and adopts multiple sensors to collect the CO , CO_2, NO, NO_2 and other toxic and harmful gas concentrations, the MCU processing, through the wireless module SRWF-1021 sent to the exhaust concentration of the total collection node, the total node data will be forwarded to the host computer, the host computer according to the received data to determine whether to open the fan System, so as to ensure that the concentration of vehicle exhaust in the parking garage is maintained in a safe range.
