摘　　要：针对二氧化碳地质储存地区环境中CO2浓度监测,基于STM32F103RE微控制器,设计了一款便携式二氧化碳监测仪,在RS232协议下,实现微控制器与传感器、液晶显示模块、U盘存储模块的数据通讯,系统中选用三个红外吸收型二氧化碳传感器,由继电器控制电路切换三个通道,实现分档采集数据,最后利用监测仪进行了室内CO2气体浓度测试实验,实验结果证明三个数据采集通道工作正常。In order to monitoring carbon dioxide concentrations in the environment of CO2 geological storage area, one kind of portable carbon dioxide monitor is designed based on STM32F103RE micro controller. To realize data communication among micro controller , sensor,LCD Module, and USB storage Module under the protocol RS232.This system adopts three infrared absorption CO2 sensors and use relay control electric circuit switch three channels to collect classified data.Finally, made use of this monitor to carry out CO2 gas concentration experiment indoor,which shows three data acquisition channels work smoothly.
