Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings.
[0024] The purpose of the invention is to track the interface wave, extract the ultrasonic data from the interface wave to the echo of the outer wall of the workpiece, and reduce the effective data volume of the detection system. The realization of the present invention is based on the ultrasonic detection system of the FPGA module, the transmission and reception of the transducer are controlled by the FPGA module, and the received data AD sampling is converted into a digital signal at the same time, and the interface wave is detected according to the position of the gate. Data extraction of outer wall echoes.
[0025] Such as figure 1 As shown, the main hardware device connections are as follows:
[0026] The ultrasonic transmitting module is connected with the transducer, the transducer is connected with the ultrasonic receiving module, and the ultrasonic receiving...
