摘要
设计了气体检测电路,通过该电路将实时数据发送到计算机;设计了动态加热系统,该系统由AT89S52单片机控制,与其他外围电路相互配合,可提供频率可调的加热电压;设计了基于LabVIEW的计算机数据处理程序,实现了对数据的处理和气体的判别。实验证明:该系统能够实现气体检测功能。
A gas detection circuit is designed for sending real-time data to PC. A dynamic heat-up system is designed. AT89S52 microcontroller controls other periphery circuits. The dynamic heat-up system can supply frequency-conversion heat-up voltage. The software based on LabVIEW is designed for data analyzing and gas distinguishing. The experiment result shows that the system can realize the function of gas measurement.
