红外烷烃光谱录井分析仪的软件开发

Software Development of Infrared Spectral Logging Unit on Alkenes

自主研发了红外烷烃光谱录井分析仪,以差分吸收光谱(DOAS)理论为基础,MFC为框架设计实现了软件的用户界面.该软件结合最小二乘法、多线程编程等技术,实现了光谱采集、显示、保存,待测气中各烷烃气体浓度的反演,以及串口的实时传输.现场测试结果表明:该软件运行稳定可靠,能实时反演出烷烃气体浓度信息,满足红外烷烃光谱录的实际现场需求.

By using MFC,a software has been designed for the user interface of Infrared Spectral Logging unit based on the theory of Differential Optical Absorption Spectroscopy（DOAS）.This software combine with a variety of techniques,such as least square method,multi-threaded programming technologies,the software implemented spectral acquisition,spectral displaying,spectral saving,concentration inversion of the paraffin gas and also the real-time transmission by the serial port.The result showed that the software was stable and reliable,and can display the real-time concentration of the alkene gas and satisfy with the factual logging needs.
