在研究超声检测技术以及高频信号采集和处理技术发展趋势和PCI总线的特点基

础上，提出了一种基于PCI总线的超声数据采集卡的实现方案。在硬件方面，系统由模

数转换模块、数据缓冲模块、接口模块和逻辑控制模块等四个功能模块构成，着重研究

了接口芯片PCI9052的数据传输方式，采用原理图+VHDL的方法设计了板卡的内部控

制逻辑和数据缓冲模块，并进行了相关的时序仿真和逻辑验证。-Ultrasonic testing in research and high-frequency signal acquisition and processing technology development trends and characteristics based on the PCI bus, a PCI bus based on ultrasound data acquisition was implemented. In hardware, the system consists of analog-digital conversion module, the data buffer module, interface module and the logic control module and other modules of four functions, and focused on the interface chip PCI9052 data transmission, using the method schematic+ VHDL design of the board The internal control logic and data buffer module, and make the relevant time simulation and logic verification.
