Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The inventor finds that most of common methods for testing the coverage rate of the TR probe are to test the coverage widths of the single receiving channels one by one, taking a one-to-three receiving probe as an example, if the effective coverage width of each receiving channel is 17mm, the total coverage width of the probe is 51mm, and if the width of the probe is 50mm, the coverage rate of the probe is 100.2%. However, the uniformity problem of each receiving channel is ignored by the method, if each receiving channel is tested independently, the influence of the difference between the receiving channels on the reflected wave of the defect is large, and in addition, if the distance between the receiving channels is large, the coverage rate of the tested probe is seriously large, so that the subsequent use of the probe is influenced.
The above prior art solutions have shortcomings which are the results of practical and careful study of the inventor, and therefore, the discovery process of the above problems and the solutions proposed by the following embodiments of the present invention to the above problems should be the contribution of the inventor to the present invention in the course of the present invention.
Based on the above research, embodiments of the present invention provide a method and an apparatus for testing probe coverage, and an electronic device, which can implement accurate test of probe coverage.
Fig. 1 shows a schematic structural diagram of a test piece 1 according to an embodiment of the present invention, and as can be seen from the diagram, the test piece 1 may be a rectangular parallelepiped, a first side surface of the test piece 1 is provided with a sliding groove 11, and a second side surface of the test piece 1 is provided with a flat bottom hole 12.
It is understood that the hole diameter of the flat-bottom hole 12 can be set according to practical situations, for example, the hole diameter of the flat-bottom hole 12 can be 3mm, and can also be 5mm, and is not limited herein. In addition, the burial depth of the flat-bottom hole 12 can also be adjusted according to different probe test requirements, and generally, the burial depth of the flat-bottom hole 12 can be 6mm to 54mm, which is not limited herein.
In the embodiment of the present application, the chute 11 is used for placing the probe, and the probe can move in the chute 11 along a set direction, wherein the set direction is the X direction in fig. 1. In practice, the probe may be held by a press block and moved in the X direction through the flat bottom hole 12 in the X direction.
Referring to fig. 2, the probe 2 includes a transmitting channel 21, a first receiving channel 221, a second receiving channel 222, and a third receiving channel 223, wherein the transmitting channel 21 is located on one side of the sound insulation layer 23, the first receiving channel 221, the second receiving channel 222, and the third receiving channel 223 are located on the other side of the sound insulation layer 23, and the first receiving channel 221, the second receiving channel 222, and the third receiving channel 223 are sequentially arranged along a set direction.
Referring to fig. 3, when the probe 2 is movably disposed in the chute 11, the first receiving channel 221, the second receiving channel 222 and the third receiving channel 223 are close to the chute 11.
Referring to fig. 4, fig. 4 is a flowchart illustrating a probe coverage testing method according to an embodiment of the invention. The specific process shown in fig. 4 will be described in detail below:
and S21, when the probe moves in the chute along the set direction, acquiring the first ultrasonic waves collected by the plurality of receiving channels.
In the embodiment of the present application, the first ultrasonic wave is a reflected wave of the second ultrasonic wave at the flat-bottom hole 12, and the second ultrasonic wave is emitted from the transmission channel 21 of the probe 2.
Referring to fig. 3, when the probe 2 moves in the sliding slot 11 along the X direction, the third receiving channel 223 first passes through the flat-bottom hole 12 along the X direction, then the second receiving channel 222, and finally the first receiving channel 221, in this process, the transmitting channel 21 emits the second ultrasonic wave, the reflection of the second ultrasonic wave at the flat-bottom hole 12 forms the first ultrasonic wave, the third receiving channel 223, the second receiving channel 222, and the first receiving channel 221 receive the first ultrasonic wave one after another, the third receiving channel 223 and the second receiving channel 222 overlap when receiving the first ultrasonic wave, and the second receiving channel 222 and the first receiving channel 221 also overlap when receiving the first ultrasonic wave. Compared with the common method for testing the coverage width of each receiving channel independently, the method provided by the embodiment of the application can take the overlapping between the adjacent receiving channels into consideration, so that the coverage rate of the probe can be accurately determined.
S22, a wave height graph is obtained based on the first ultrasonic wave and the position of the probe in the set direction.
In the embodiment of the present application, the wave height refers to a vertical distance between adjacent peaks and valleys, and by acquiring the first ultrasonic waves collected by the first receiving channel 221, the second receiving channel 222, and the third receiving channel 223, and combining the position (displacement) of the probe 2 relative to the test piece 1 when moving in the X direction, a wave height graph reflecting the relationship between the displacement and the wave height can be obtained, as shown in fig. 5. The wave height graph of fig. 5 includes a first wave height curve P1, a second wave height curve P2, and a third wave height curve P3. In fig. 5, the abscissa is the position of the probe 2 relative to the test piece 1, which can be understood as relative displacement, and the ordinate is the wave height value.
It is understood that the first wave height profile P1 is derived from the position relative to the test piece 1 when the probe 2 is moved in the X direction and the first ultrasonic waves collected by the first reception channel 221, the second wave height profile P2 is derived from the position relative to the test piece 1 when the probe 2 is moved in the X direction and the first ultrasonic waves collected by the second reception channel 222, and the third wave height profile P3 is derived from the position relative to the test piece 1 when the probe 2 is moved in the X direction and the first ultrasonic waves collected by the third reception channel 223.
The first, second and third wave height curves P1, P2 and P3 are used to test whether the coverage path of the probe 2 is acceptable.
In the embodiment of the present application, the unit of the wave height is dB.
And S23, determining the superposition margin of the probe according to the wave height curve graph.
In the embodiment of the application, the superposition margin of the probe is determined according to the wave height curve graph, and the method is specifically realized by the following steps:
firstly, determining a maximum wave height value Amax from a first wave height curve P1, a second wave height curve P2 and a third wave height curve P3;
and secondly, obtaining a reference wave height value according to the maximum wave height value and a preset wave height value increment.
The preset wave height value increment may be determined according to the sensitivity drop value of the probe 2, for example, the preset wave height value increment may be Ax, and the reference wave height value Ac ═ Amax-Ax.
Then, a first wave height value Ao1 at the intersection of the first wave height curve P1 and the second wave height curve P2 and a second wave height value Ao2 at the intersection of the second wave height curve P2 and the third wave height curve P3 are determined.
Finally, according to the first wave height value A12 and the reference wave height value Ac, the first superposition margin Ay 1-Ao 1-Ax of the probe 2 is determined, and the second superposition margin Ay 2-Ao 2-Ax of the probe 2 is determined.
And S24, judging whether the coverage rate of the probe is qualified or not according to the superposition allowance.
In the embodiment of the application, whether the coverage rate of the probe is qualified or not is judged according to the superposition allowance, and the method is realized by the following specific steps:
judging whether the first superposition margin Ay1 and the second superposition margin Ay2 are both larger than or equal to zero;
if both the first superimposition residual amount Ay1 and the second superimposition residual amount Ay2 are equal to or greater than zero, the process proceeds to S25.
If the first superimposition residual amount Ay1 is less than zero or the second superimposition residual amount Ay2 is less than zero, the routine proceeds to S26.
And S25, judging that the coverage rate of the probe is qualified.
And S26, judging that the coverage rate of the probe is not qualified.
Specifically, when ultrasonic flaw detection is performed on a flat-bottom hole having a buried depth of 18mm and an aperture of 5mm, and the preset wave height increment is 6dB, as shown in fig. 5, the first overlap margin Ay1 is Ao1-Ax which is 0.3dB, and the second overlap margin Ay2 is Ao2-Ax which is 1.7dB, it can be understood that both the first overlap margin and the second overlap margin are larger than zero, and thus it can be determined that the coverage of the probe 2 is acceptable.
In S26, if the first overlap margin Ay1 is less than zero or the second overlap margin Ay2 is less than zero, specifically, if the first overlap margin Ay1 and the second overlap margin Ay2 are not equal to or greater than zero at the same time, it indicates that there is no overlap between the first receiving channel 221 and the second receiving channel 222, or there is no overlap between the second receiving channel 222 and the third receiving channel 223, and in this case, it indicates that the distance between the first receiving channel 221 and the second receiving channel 222, or the distance between the second receiving channel 222 and the third receiving channel 223 is too large, which may cause a false detection phenomenon in each receiving channel when performing flaw detection on the same flat-bottom hole.
In the embodiment of the application, the multiple receiving channels can simultaneously acquire the first ultrasonic waves, the wave height curve graph is generated based on the first ultrasonic waves acquired by each receiving channel, and whether the coverage rate of the probe 2 is qualified or not is judged on the basis of the wave height curve graph.
