高速大容量数据采集系统设计与实现

Design of High-speed and Large-scale Data Acquisition System

高速、高精度、大容量数据采集系统对系统速度、精度、数据存储等各方面都提出了更高的要求,本文基于高速数据采集系统的结构,详细讨论了信号调理、时钟产生、数据存储与传输、抗干扰等关键技术以及采取的相应措施,最后介绍了双通道AD9430高速数据采集卡,并给出了测试结果。

The implementation of the high-speed, high-precision and large-scale data acquisition system requires rigorous requests on speed, precision, data storage and so on. Based on the structure of the high speed data acquisition system, the key techniques, including the analog signal adjusting circuits, clock circuit design, data storage and transmission, anti-interference and etc, are analyzed in detail. And the corresponding measures are discussed. As a typical application, dual-channel AD9430 high-speed data acquisition board are introduced briefly. The test results of the board are given.
