随机采样技术在数据采集系统中的应用

Application of Random Sampling Technology to the System of Data Acquisition

随着计算机科学和电子技术的高速发展,数据采集系统已广泛应用于工业、国防、科研等各个领域。由于实时采样技术对信号的捕捉要受采样速率的限制,必须采用高速A/D转换器以及高精度、高性能的硬件支持才能完成。而随机采样技术弥补了这一限制。本文主要介绍基于随机采样数据采集系统的开发流程,并详述随机采样系统的设计。

With the rapid development of computer science and electronic technology,data acquisition system has been widely applied in many fields, including industry, national defense, and scientific research and so on. Since the capture of signal is strictly limited to the sampling rate when real-time sampling technology is used, it need high-speed A/D converter and some hardware with high accuracy and high performance to realize the function. Random sampling technology overcomes such limitation. In this paper, the whole development procedure based on data acquisition system using random sampling technology, and descripts it in detail.
