摘　　要：为了实时监测环境中的CO和O2浓度,设计了一种基于LabVIEW的多路气体检测系统。该检测系统通过电化学传感器采集气体浓度信息,C8051F020完成信号的A/D转化和电化学传感器的温度补偿,并将多通道数据通过串口发送到上位机。上位机使用LabVIEW进行编程,从而实现数据的采集、处理、分析、显示、保存及自校准标定功能。该系统具有检测精度高、结构简单、检测方便、界面友好等特点。In order to measure carbon monoxide and oxygen content,a multi-channel gas detection system was designed based on LabVIEW.The system acquired concentration of gas by electrochemical gas sensor.C8051F020 completed AD conversion and temperature compensation of electrochemical sensor,and sent multi-channel data to the computer through the serial port.Using LabVIEW software programming,data acquisition,data analysis,data display,data storage and function of self-calibration were realized.The system has the advantages of high accuracy,simple structure,friendly interface and convenient detection.
