摘要
在光化学烟雾物理模拟的实验中,需要设计并建立一套可靠的数据采集系统,实现对实验数据的读取、分离、处理、显示、记录等操作。我们采用图形化编程语言LabVIEW编制的数据采集系统软件,能自动完成对光化学过程的反应条件和反应中各种物质浓度长时间连续采集,并能在线反映各种参数随时间的变化。本文介绍了系统的硬件组成和软件设计,以及保证系统稳定性方面采取的一些措施,并对其可用性进行检验。
A reliable data acquisition system was designed and developed for the physical simulation of photochemical smog, which is used to input, separate, manage, display and record the experimental data. The soft in this system, programmed by graphic language Lab VIEW, could not only automatically acquire reaction conditions and concentrations of all kinds of species in long-time photochemical process, but also show the on-line change of parameters. The hardware and software of this system as well as some measures for keeping the system more stable are introduced in this paper, which were verified in experiment.
