| Abstract: | In order to satisfy the real-time requirements of ultrasonic flaw detecting, a study of operational principle of ultrasonic flaw detecting is made. The implementation scheme and hardware architecture design of signal processing system with realtime capability are designed based on FPGA, and the software design adopts modularized approach by using the logic structural model of FPGA. Experiments and statistical data show that the signal processing system based on FPGA can improve the accuracy and stability when used in flaw detecting, and the requirements of B-scan display with the real-time processing capability can be met. |
