摘要: 激光气体遥测仪是基于红外气体吸收光谱原理,采用先进的可调谐半导体激光吸收光谱(TDLAS)技术分析测量被测区域(如传输管道、天花板、墙体等)内的甲烷气体平均浓度的新型仪表。性能优良的激光气体遥测仪表已在许多危险领域得到了广泛的应用,但是,目前整机测试系统流程复杂、费时、低效。结合相关生产实践开发一种较为实用的整机测试自动化软件,以提高整机测试的效率。目前已有效地帮助生产相关人员快速、准确地完成整机测试流程。

Abstract: Laser gas remote sensing instrument is a kind of new type instrument which can analyze and detect average concentration of CH4 in the detecting area (for example, transmission pipeline, ceiling, wall and so on) with an advanced technology called tunable diode laser absorption spectroscopy(TDLAS). Laser gas remote sensing instrument with good performance has been widely applied in many dangerous areas. At present, however, the testing process of manufacturing testing system extremely complex, time-wasting and inefficient, completely manually operate. The purpose of this paper is to design and develop an automatic testing software combined with related practice, to improve work efficiency. The study harvest of this paper lies in designing a simple, practical and stable PC testing software. Now, this software helps people to work on product line quickly and accurately complete testing process.

引 言
随着社会的发展,生产技术水平的不断提高,钢铁冶金、气体管道传输、化工等行业生产力需不断提高,但必须保障生产安全。基于可调谐半导体激光吸收光谱(TDLAS)技术的激光气体遥测仪已经成为提高生产效率、保障安全生产的重要仪器。如此的社会需求激起了国内外仪表厂商的极大的研究兴趣,激光遥测仪表的市场竞争愈演愈烈。
20世纪90年代后期,随着半导体激光器的大规模生产及科学研究的应用,TDLAS技术得到了迅速发展。21世纪初期,该技术逐渐被国内的研究者关注,现在已有很多企业推出了激光气体遥测仪,并投入使用,同时,国内也制定了激光器产品及分析仪器的相关国标。但是大多数国标也只是针对激光器产品准则与分析仪器通用准则,对整机测试系统的设计与研究并没有深入。……
