Abstract

The invention discloses an ultrasonic guided wave imaging detector and a method thereof. A field programmable logic array in a guided wave signal acquisition system is used for controlling a guided wave signal execution circuit for generating a guided wave detection signal, the signal is collected and processed by the field programmable logic array and transmitted to an imaging system through a PCIE bus, after transmitted guided wave detection data is received by the imaging system through the PCIE bus, imaging processing is performed through an embedded multi-core processor, and the processedsignal is sent to a display panel through an LVDS display signal line for display. Through the embedded multi-core processor, power consumption of the whole machine is reduced, the PCIE bus is employed to simplify the circuit connection relationship for high-speed signal communication between two systems, and a graphics processor (GPU) integrated in the embedded multi-core application processor achieves good real-time imaging while maintaining low power consumption.

Description

Technical field [0001] The invention belongs to the technical field of ultrasonic nondestructive testing, and particularly relates to an ultrasonic guided wave imaging detector and an operating method thereof. Background technique [0002] Ultrasonic guided wave testing is a special and proprietary ultrasonic nondestructive testing method, which is generally suitable for the detection of material missing in a whole piece of uniform and regular metal materials. At present, when the existing ultrasonic non-destructive testing instruments implement ultrasonic guided wave testing, they usually use the general functions of ultrasonic testing to complete, and the test results are generally displayed in the form of ultrasonic echo waveforms. For testing operators, the test results The judgment of is not intuitive, and there are many difficulties in understanding. In general, there is currently a lack of instruments specifically designed for ultrasonic guided wave detection applications...
