Description
Technical Field
The application relates to the technical field of flaw detection, in particular to a method and a device for detecting phantom waves in a round bar and a storage medium.
Background
Ultrasonic detection is an important means for detecting the internal quality of a compact elastic material workpiece such as a metal material, and when in detection, a probe transmits ultrasonic waves to a workpiece medium, the ultrasonic waves encounter a heterogeneous interface in the workpiece medium to generate reflection, and part of the ultrasonic waves return to a reflection signal at a corresponding position in an instrument after the probe is received, so that the internal quality condition of the workpiece is judged.
In a round bar production enterprise, automatic ultrasonic detection is generally performed by adopting a local water immersion method, and a sound field of a straight-moving probe of the round bar rotates around the round bar during detection to realize spiral scanning of the round bar. The probe and the round bar are filled with coupling water, ultrasonic waves emitted from the probe enter the round bar through the coupling water, reflected signals are formed in corresponding display ranges in the instrument when the round bar is defective, and a gate arranged on the instrument captures the signal amplitude conditions in the corresponding display ranges to judge the internal quality conditions of the round bar. In general, the signal appearing in the round bar range is a defect signal, and in actual detection, some fixed signals often appear in the round bar range, however, the signal shows a position detection verification but a defect-free signal, and the corresponding position anatomical verification can not find the defect.
The presence or absence and location of such non-defective signals in rod detection is ambiguous, and such signals are referred to in the industry as "phantom waves". Phantom waves are prone to batch misinterpretations in automatic ultrasound detection. Therefore, how to identify (and cope with) phantom waves in round bars is an urgent problem to be solved.

Referring to fig. 2, fig. 2 is a flowchart of a method for detecting a phantom wave in a round bar applied to the electronic device 100 of fig. 1, and the method includes various steps described in detail below.
Step 201: a first initial wave signal, a first primary boundary wave signal, a first primary bottom wave signal and a first other signal in the detection structure are obtained.
Step 202: a display map of the first initial wave signal, the first one-time boundary wave signal, the first one-time bottom wave signal, and the first other signal is determined.
The display chart shows corresponding display positions reached at different moments, the detection structure comprises a probe, a detection cavity and a round bar, the round bar passes through the inside of the detection cavity, coupling water is filled in the detection cavity, the probe is arranged on the inner wall of the detection cavity, the probe scans around the round bar in a spiral mode during detection, the probe sends out ultrasonic waves to the coupling water, the ultrasonic waves are reflected to the probe through the coupling water to obtain first initial wave signals, the ultrasonic waves are transmitted to the side wall of the round bar and then reflected to the probe to obtain first interface wave signals, and the ultrasonic waves are transmitted to the side wall of the round bar and then transmitted to the bottom in the round bar and then reflected to the probe to obtain first bottom wave signals.
Step 203: and adjusting the detection parameters to obtain a second initial wave signal, a second primary interface wave signal, a second primary bottom wave signal and a second other signal in the adjusted detection structure.
Step 204: a first residual signal of the first other signal and a second residual signal of the second other signal are determined.
Step 205: and when the display positions of the first initial wave signal and the second initial wave signal, the first primary interface wave signal and the second primary interface wave signal, and the first primary bottom wave signal and the second primary bottom wave signal are consistent, and the display positions of the first residual signal and the second residual signal are inconsistent, determining that the first residual signal is a phantom wave.
In the water immersion ultrasonic detection of the round bar, the ultrasonic waves are transmitted and reflected once in the water/round bar and the round bar/water interface, and according to the propagation speed conditions of the ultrasonic waves in the water and the round bar, the propagation process of the primary pulse ultrasonic waves in the water and the round bar is decomposed into a propagation time and a process of displaying two relevant quantities of positions, so that a time-position diagram of the propagation of the ultrasonic waves in a medium is drawn.
Referring to fig. 3, a time-position diagram of the first initial wave signal 1, the first one-time boundary wave signal 2, the first one-time bottom wave signal 3, and the first other signal 4 is shown, in which the horizontal direction indicates the time of ultrasonic propagation, and the vertical direction indicates the position where the ultrasonic waves in the water and the round bar reach at a certain time, and the ultrasonic propagation direction at that time is displayed.
Referring to fig. 4, a schematic diagram of a detection structure is shown, where the detection structure includes a probe 5, a detection cavity 6 and a round bar 7, the probe emits a pulse ultrasonic wave once, and the instrument is cleared by zero when timing, the pulse ultrasonic wave encounters a heterogeneous interface each time and reflects and transmits.
The signal display range at least comprises a first initial wave signal, a first one-time interface wave signal and a first one-time bottom wave signal, when a round bar is defective, a defect reflection signal is displayed, if the pulse signal display range is enlarged, more round bar/water reflection signals similar to the water/round bar interface reflection signal and the bottom surface are displayed. In this case, in addition to the first initial wave signal, the first one-time boundary wave signal and the first one-time bottom wave signal, there are a plurality of first other signals displayed at the fixed position formed by the arrival probe of the residual ultrasonic wave of the previous pulse, wherein the first other signals include the first residual signal.
