【摘要】:基于计算机平台的超声诊断仪是将经过各种转换处理后含有原始诊断的数字信号传输到计算机上,再使用计算机软件处理数据来还原超声图像,而该信号要求能够高速、实时、安全地通过计算机接口传输到PC机上。在常用的计算机总线中,不难发现USB(通用串行总线)具有体积小、兼容性好、即插即用、支持热插拔、成本低及节省系统资源等优点,其中USB3.0标准可以高达5.0Gbit/s的传输速率,同时USB接口已经成为PC机主流的接口。本文提出基于USB3.0的数据传输系统,实现外部数字信号高速实时地传输到计算机上。 本课题主要研究的内容有:首先,根据课题研究目的设计硬件总方案框图,绘制原理图及PCB板,焊接和调试硬件电路,实现数据传输系统的硬件平台;其次,生成GPIF Ⅱ接口波形描述符,设计和开发固件程序;再次,开发FPGA程序,实现FPGA对USB3.0处理器的时序逻辑控制;最后,开发驱动程序和上位机软件,实现软件与硬件的交互。 该数据传输系统主要实现了将外部数字信号通过USB3.0接口高速实时地传输到计算机上,利用上位机软件实时显示USB设备基本信息及传输数据波形,并测试USB3.0的传输速率,为需要高速传输的基于计算机接口的设备提供了应用参考。
[Abstract]:The ultrasonic diagnostic instrument based on the computer platform transmits the digital signal which contains the original diagnosis after all kinds of conversion processing to the computer, and then uses the computer software to process the data to restore the ultrasonic image, and the signal needs to be high speed and real time. It is safely transmitted to the PC through the computer interface. In the common computer bus, it is not difficult to find that USB (Universal Serial bus) has the advantages of small size, good compatibility, plug and play, hot plug and play, low cost and saving system resources, among which USB3.0 can achieve a transmission rate of 5.0 Gbit / s. At the same time, USB interface has become the mainstream of PC interface. In this paper, a data transmission system based on USB3.0 is proposed, which can transmit external digital signals to computer at high speed and in real time. The main contents of this research are as follows: firstly, the hardware block diagram, the schematic diagram and PCB board, welding and debugging hardware circuit are designed according to the purpose of the research; secondly, the hardware platform of the data transmission system is realized.
