Design of Data Acquisition and Control System Based on FPGA and DSP in Ultrasonic Inspection of Pipelines

It is disturbed easily by peripheral environments for ultrasonic inspection of pipelines. So completing data acquisition and processing have become important for research. In the signal of pipeline ultrasonic inspection, FPGA and DSP based methodology has been put forward to accomplish data acquisition and control system. The system´s digital circuit function achieved by FPGA, as well as device communication and system control achieved by DSP. The simulation result shows that ultrasonic inspection signal data can be picked up and controlled intelligently to ensure the reliability of ultrasonic inspection of pipelines.
