随着科研工作的大量增加,应用计算机采集和处理实验数据已成为当务之急。目前,关于数据采集和处理的资料很多,但均以A/D、D/A转换,数字处理为主,构成一套成整的数据采集系统的资料却非常少。尤其在实际应用中,专用的数据采集系统是必不可少的。因此,本文从实际应用出发,叙述了小型风洞实验数据采集系统的软硬件之构成,重点叙述了风洞实验中对计算机的遥控装置。
With the massive increase of scientific research, the application of computer to collect and process experimental data has become a top priority. At present, there is a lot of information on data collection and processing, but most of them are based on A / D, D / A conversion and digital processing. However, there is very little data to form a complete data collection system. Especially in practical applications, a dedicated data acquisition system is essential. Therefore, starting from the practical application, this paper describes the hardware and software of a small wind tunnel experimental data acquisition system, and focuses on the computer remote control device in the wind tunnel experiment.
