| 摘 要： | 本文提出了一种基于CPLD的高速数据采集系统的设计方法。通过CPLD控制数据连续采集、缓冲,然后通过单片机(C8051F430)读取缓存在SRAM中数据,并且通过USB2.0将缓冲区数据转移到硬盘管理卡,由硬盘管理卡将数据存入海量硬盘。再利用PC机的强大数据处理功能,配合Microsoft VisualC++6.0的MFC类库,设计出一套集数据采集、处理和分析的可视化系统。

| Abstract: | This paper presents a high-speed data acquisition system design based on CPLD.Through the CPLD control data continuous acquisition, buffering, then the microcontroller (C8051F430) read the data from the SRAM and buffer data transfer via USB2.0 to the management card to the hard disk, a hard drive management card data into massive hard drive. Using a PC powerful data processing capabilities, with Microsoft Visual C + + 6.0 of the MFC class library, design a set of data acquisition, processing and analysis of the visual system |
