摘要
为监控环境中的二氧化碳浓度,设计出基于FreeRTOS的二氧化碳浓度检测及上位机系统,采用FreeRTOS管理调度STM32线程任务,执行采集二氧化碳浓度、蓝牙无线通信、运行状态指示等任务,通过二氧化碳传感器采集二氧化碳的含量,并将该数据通过蓝牙上传至Qt用户界面进行显示、存储及分析的试验,实现了对环境中二氧化碳浓度的检测和数据分析,根据采集的二氧化碳浓度数据与分析结果,可以判断环境二氧化碳浓度是否超标,进而为评估环境质量提供依据。
In order to monitor the concentration of carbon dioxide in the environment,a carbon dioxide detection and host computer system based on FreeRTOS is designed.FreeRTOS is used to manage and schedule STM32 thread tasks,and perform tasks such as carbon dioxide concentration collection,Bluetooth wireless communication,running status indication,etc.The content of carbon dioxide is collected by the carbon dioxide sensor,and the data is uploaded to the Qt user interface through Bluetooth for display,storage and analysis.According to the collected CO2 concentration data and analysis results,it can be determined whether the environmental CO2 concentration exceeds the standard,and then provide a basis for evaluating environmental quality.
