Description

Technical Field

[0001] This application relates to the field of flaw detection technology, and more specifically, to a method, apparatus and storage medium for detecting phantom waves in a round bar. Background Technology

[0002] Ultrasonic testing is an important method for inspecting the internal quality of dense, elastic materials such as metals. During testing, the probe transmits ultrasonic waves into the workpiece medium. When the ultrasonic waves encounter heterogeneous interfaces in the workpiece medium, they are reflected. Some of the reflected waves return to the probe and are received. The reflected signals at the corresponding positions are then displayed in the instrument, thereby determining the internal quality of the workpiece.

[0003] In round bar manufacturing enterprises, a localized water immersion method for automated ultrasonic testing is commonly used. During testing, the probe's acoustic field rotates around the round bar to perform a helical scan. The space between the probe and the bar is filled with coupling water. Ultrasonic waves emitted from the probe pass through the coupling water into the bar. When a defect exists in the bar, a reflected signal is generated within the corresponding display range on the instrument. A gate on the instrument captures the signal amplitude within this range to determine the internal quality of the bar. Generally, a signal appearing within the sound path range of the round bar is considered a defect signal. In actual testing, some fixed signals often appear within the sound path range of the round bar; however, no defect signal is found when the location of these signals is examined, and dissection of the corresponding location also fails to reveal any defects.

[0004] The presence and location of this non-defect signal in round bar inspection are unpredictable; in the industry, this signal is called a "phantom wave." Phantom waves can easily cause batch misjudgments in automated ultrasonic testing. Therefore, how to identify (and deal with) phantom waves in round bars is an urgent problem to be solved. Summary of the Invention

[0075] This embodiment provides an electronic device capable of training a phantom wave detection model in a circular bar. In one possible implementation, the electronic device can be a signal display.

[0080] Please refer to Figure 2 , Figure 2 For application Figure 1 The flowchart below shows a method for detecting phantom waves in a round bar of an electronic device 100. The method includes a detailed description of each step.

[0081] Step 201: Acquire the first initial wave signal, the first primary interface wave signal, the first primary bottom wave signal, and the first other signals in the detection structure.

[0082] Step 202: Determine the display diagram of the first initial wave signal, the first primary interface wave signal, the first primary bottom wave signal, and the first other signals.

[0083] The display diagram shows the corresponding display positions reached at different times. The detection structure includes a probe, a detection cavity, and a cylindrical rod. The cylindrical rod passes through the inside of the detection cavity, which is filled with coupling water. The probe is set on the inner wall of the detection cavity. During detection, the probe rotates around the cylindrical rod in a spiral scan. The probe emits ultrasonic waves into the coupling water. The ultrasonic waves are reflected back to the probe by the coupling water to obtain the first initial wave signal. The ultrasonic waves are transmitted through the coupling water to the side wall of the cylindrical rod and reflected back to the probe to obtain the first primary interface wave signal. The ultrasonic waves are transmitted through the side wall of the cylindrical rod and transmitted to the bottom inside the cylindrical rod and reflected back to the probe to obtain the first primary bottom wave signal.

[0084] Step 203: Adjust the detection parameters and obtain the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signals in the adjusted detection structure.

[0085] Step 204: Determine the first residual signal among the first other signals and the second residual signal among the second other signals.

[0086] Step 205: 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, the first residual signal is determined to be a phantom wave.

[0087] In the ultrasonic immersion test of a round bar, the ultrasonic wave is transmitted and reflected every time it encounters the water / round bar and the round bar / water interface. Based on the propagation speed of the ultrasonic wave in the water and the round bar, the propagation process of a single pulse ultrasonic wave in the water and the round bar is decomposed into two related quantities: propagation time and display position. Thus, a time-position diagram of the ultrasonic wave propagation in the medium is drawn.

[0088] Reference Figure 3 This is a time-position diagram consisting of the first initial wave signal 1, the first primary interface wave signal 2, the first primary bottom wave signal 3, and the first other signals 4. The horizontal direction represents the time of ultrasonic wave propagation, and the vertical direction represents the position of the ultrasonic waves in the water and the rod at a certain moment. It also shows the direction of ultrasonic wave propagation at that moment.

[0089] Reference Figure 4The diagram shows the detection structure, which includes a probe 5, a detection cavity 6, and a cylindrical rod 7. The probe emits a pulse of ultrasonic wave while the instrument's timer is reset to zero. Each time the pulse of ultrasonic wave encounters a heterogeneous interface, it is reflected and transmitted... Ultrasonic waves travel through various propagation paths and return to the probe at different times to be received and form a display signal. In the pulse signal display, the position of the initial wave signal corresponds to the time at the probe / coupled water interface, the position of the first interface wave signal corresponds to the time when the ultrasonic wave is reflected once at the water / cylinder interface and returns to the probe, and the position of the first bottom wave corresponds to the time when the ultrasonic wave, after passing through the cylindrical rod, is reflected once at the cylindrical rod / coupled water and reaches the probe.

[0090] The signal display range includes at least the first initial wave signal, the first primary interface wave signal, and the first primary bottom wave signal. If there is a defect in the rod, the defect reflection signal will be displayed. If the pulse signal display range is expanded, more signals similar to the water / rod interface reflection signal and the bottom rod / water reflection signal will be displayed... After one cycle, the probe emits an ultrasonic pulse again, and the instrument displays zero again, but the residual ultrasonic waves from the previous pulse are still propagating. At this time, in addition to the first initial wave signal, the first primary interface wave signal, and the first primary bottom wave signal, the signal display range also includes numerous other signals displayed at the fixed position formed by the residual ultrasonic waves from the previous pulse reaching the probe. These other signals include the first residual signal.

[0091] In order to filter out phantom waves in the first other signal, the detection parameters are adjusted, and an ultrasonic signal is emitted based on the adjusted probe. The second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signal received by the probe after adjustment are acquired again.

[0092] After adjusting the detection parameters, the display positions of the second initial wave signal, the second primary interface wave signal, and the second primary bottom wave signal remain unchanged compared to the first primary interface wave signal. When damage exists in the round bar, the display positions of the defect signals in the first and second other signals remain unchanged; only the display position of the first residual signal in the first other signals changes compared to the display position of the second residual signal in the second other signals. Therefore, the first residual signal in the first other signals is determined to be a phantom wave.

[0093] There are multiple ways to determine the phantom wave based on the first initial wave signal, the second initial wave signal, the first primary interface wave signal, the second primary interface wave signal, the first primary bottom wave signal, the second primary bottom wave signal, the first residual signal, and the second residual signal. In one such method, such as... Figure 5 As shown, it includes the following steps:

[0094] Step 301: Increase the pulse frequency of the ultrasonic waves emitted by the probe.

[0095] Step 302: Obtain the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signals from the adjusted detection structure.

[0096] Step 303: 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 position of the first residual signal is smaller than the display position of the second residual signal, the first other signal is determined to be a phantom wave, and the first residual signal is determined to be a phantom wave.

[0097] Besides increasing the pulse frequency of the ultrasonic waves emitted by the probe, it is also possible to:

[0098] Reduce the pulse frequency of the ultrasonic waves emitted by the probe, and acquire the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and other signals in the adjusted detection structure. 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 position of the first residual wave is greater than the display position of the second residual signal, the first residual signal is determined to be a phantom wave.

[0099] Changing the pulse frequency changes the pulse period accordingly. The phantom wave will move back and forth on the display screen. Increasing the pulse frequency and shortening the period will move the phantom wave backward, and vice versa.

[0100] In another method for determining the phantom wave based on the first initial wave signal, the second initial wave signal, the first primary interface wave signal, the second primary interface wave signal, the first primary bottom wave signal, the second primary bottom wave signal, the first residual signal, and the second residual signal, such as... Figure 6 As shown, it includes the following steps:

[0101] Step 401: Increase the water path distance between the probe and the round bar.

[0102] Step 402: Obtain the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signals from the adjusted detection structure.

[0103] Step 403: If 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 position of the first residual signal is greater than the display position of the second residual signal, then the first residual signal is determined to be a phantom wave.

[0104] Besides increasing the water path distance between the probe and the rod, it is also possible to:

[0105] Reduce the water path distance between the probe and the round bar; acquire the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signals in the adjusted detection structure; if 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 position of the first residual signal is smaller than the display position of the second residual signal, then the first residual signal is determined to be a phantom wave.

[0106] Adjusting the probe position changes the water path distance of the coupling water. Decreasing the water path distance moves the phantom wave position forward until the phantom wave, which is reflected back and forth in the water path, moves out of the gate. At the same time, the number of reciprocations in the water path increases, the attenuation increases, and the amplitude of the phantom wave decreases. Increasing the water path distance moves the phantom wave position backward until the phantom wave, which is reflected back and forth in the water path, moves out of the gate. At the same time, the attenuation of the ultrasonic wave by the coupling water increases, and the amplitude of the highest phantom wave decreases.

[0107] In another method for determining the phantom wave based on the first initial wave signal, the second initial wave signal, the first primary interface wave signal, the second primary interface wave signal, the first primary bottom wave signal, the second primary bottom wave signal, the first residual signal, and the second residual signal, such as... Figure 7 As shown, it includes the following steps:

[0108] Step 501: Reduce the pulse frequency of the ultrasonic waves emitted by the probe and reduce the water path distance between the probe and the round bar.

[0109] Step 502: Obtain the second initial wave signal, the second primary interface wave signal, the second primary bottom wave signal, and the second other signals from the adjusted detection structure.

[0110] Step 503: If 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 position of the first residual signal is smaller than the display position of the second residual signal, then the first residual signal is determined to be a phantom wave.

[0111] Furthermore, by increasing the pulse frequency of the ultrasonic waves emitted by the probe and increasing the water path distance between the probe and the round bar, if 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 position of the first residual signal is greater than the display position of the second residual signal, then the first residual signal is determined to be a phantom wave.

[0112] Finally, based on the first display position of the first residual signal and the second display position of the second residual signal, the detection parameters are adjusted to move the second residual signal out of the signal detection area, obtain the detection signal in the signal detection area, and detect the damage to the round bar based on the detection signal.

[0113] For example, the difference between the first display position of the first residual signal and the second display position of the second residual signal is calculated, the target adjustment parameter to which the difference belongs is determined, and the detection parameter is adjusted based on the target adjustment parameter so that the second residual signal can be moved out of the signal detection area, so that the signal detected in the signal detection area does not have a phantom wave, thereby improving the accuracy of the round bar flaw detection based on the detection signal without phantom waves.

[0114] Different differences correspond to different adjustment parameters. For example, different ultrasonic pulse frequencies correspond to different differences, and different water distances correspond to different differences.
