| 摘 要： | 根据便携式高速数据采集的要求,设计并完成了一套基于通用串行总线(USB)2.0协议的高速数据采集系统。对数字信号处理器(DSP)的主机接口(HPI)、USB芯片的通用可编程接口(GPIF)和端点以及USB固件程序和PC主机应用程序的编写进行了介绍。该系统使用TI公司的C6000系列高性能DSP芯片作为系统核心,并经由USB接口芯片与PC主机相连接,实现采样系统与PC主机之间的高速数据传输。DSP高速数据采集系统应用于大型发电机局部放电在线监测中,实现了局部放电信号的检测和重构。

| Abstract: | On the purpose of portable high speed data acquisition,a high speed data acquisition system based on USB2.0 protocol was developed.It used the TI's C6000 series DSPs as the core part and realized the high data transfer speed by the USB interface chip.Details about the HPI(host-port interface) of DSP,the GPIF(general programmable interface) and endpoints of USB chip,the firmware program of USB chip,the application program of PC host and so on were depicted.The acquisition system was applied to partial discharge on-line monitoring,and realized the detection and reconstruction of partial discharge signals. |
