摘　　要：介绍了一款高性能超声波探伤仪的模块化系统设计方案。前端以FPGA为主控,进行100 Mbit/s数据的高速采集和处理,使用FT232H实现USB高速数据传输,后端以S5PV210处理器为控制核心,实时分析和处理回波数据。基于QT/Embedded图形界面开发环镜,设计了探伤系统人机交互界面,实现了探伤控制、2D加速波形实时显示、存储等功能。通过整体性能测试表明,该设计方案能够满足现实应用中波形显示的实时性和探伤结果的高性能要求。A solution of a kind of design about high-performance ultrasonic testing system was presented in this paper. Front- end FPGA, as master, was primarily responsible for data acquisition and processing at 100 Mbit/s, and used FT232H to realize USB high speed data transmission. S5PV210 processor, as the control core of the back-end,was to analyze and process the sampling da- ta. The software design of ARM-side was based on QT/Embedded GUI development environment. It realized the system function on data acquisition,2D accelerated real-time display and storage. The performance evaluation demonstrates that this solution can meet the requirements of real-time capabilities and high-performance in practical application.
