Abstract

In this work, a new and low-cost Arduino-Based Data Acquisition System (ABDAS) for use in an aerodynamics lab is developed. Its design is simple and reliable. The accuracy of the system has been checked by being directly compared with a commercial and high accuracy level hardware from National Instruments. Furthermore, ABDAS has been compared to the accredited calibration system in the IDR/UPM Institute, its measurements during this testing campaign being used to analyzed two different cup anemometer frequency determination procedures: counting pulses and the Fourier transform. The results indicate a more accurate transfer function of the cup anemometers when counting pulses procedure is used.

摘要

在这项工作中，开发了一种新的、低成本的基于 Arduino 的数据采集系统（ABDAS），用于空气动力学实验室。它的设计简单可靠。该系统的准确性已经通过与商业的、高精度级别的 National Instruments 硬件直接比较进行了检查。此外，ABDAS 还与 IDR/UPM 研究所的认可校准系统进行了比较，在该测试活动期间，使用其测量结果来分析两种不同的杯式风速计频率确定程序：计数脉冲和傅里叶变换。结果表明，当使用计数脉冲程序时，杯式风速计的传递函数更准确。
