Description

Technical Field

[0001] This invention relates to the technical field of transducer testing, and more specifically, to a transducer echo line sequence testing method and a transducer echo line sequence testing device. Background Technology

[0002] As the core component of intracardiac ultrasound, the performance of the ultrasound transducer directly determines the quality of ultrasound imaging, the precision of surgical guidance, and the feasibility of clinical applications.

[0003] Ultrasonic transducers typically include phased array, linear array, convex array, and intracavity types. They generally have 64 or more independent array elements. During the manufacturing process, the electrical and acoustic performance of each channel is usually tested. In a multi-element ultrasonic transducer, each element is sequentially excited during operation, emitting and receiving corresponding ultrasonic waves. The acoustic-electric signals are then converted and transmitted to a host computer for display of the ultrasonic images via connected cables.

[0004] However, the transducer testing devices of the relevant technologies can only perform electrical performance testing or acoustic performance testing. When testing ultrasonic transducers, it is necessary to test the electrical and acoustic performance separately, which increases the time and cost of ultrasonic transducer testing. Summary of the Invention

[0006] The embodiments of the present invention achieve the above objectives through the following technical solutions.

[0007] In a first aspect, embodiments of the present invention provide a transducer echo line sequence testing method, applied to a transducer echo line sequence testing device, which has an echo detection state and a line sequence detection state.

[0008] Secondly, embodiments of the present invention provide a transducer echo line sequence testing device, applied to a transducer echo line sequence testing device, which has an echo detection state and a line sequence detection state. The transducer echo line sequence testing device includes: a device body, a transducer detection module with a detection surface, and a transducer with multiple test array elements; the device includes: a first execution module, used to determine the performance result of the transducer by comparing the waveform data of the feedback signal obtained by the ultrasonic signal emitted by the multiple test array elements after reflection by the detection surface with preset qualified data when the transducer echo line sequence testing device is in the echo detection state and the detection surface is set at a first angle with the horizontal plane; and a second execution module, used to determine the actual flight time difference of each adjacent test array element in the multiple test array elements by determining the actual flight time difference value and the theoretical flight time difference value based on the comparison relationship between the difference between the actual flight time difference value and the theoretical flight time difference value and the preset threshold value.

[0009] Thirdly, embodiments of the present invention provide a transducer echo line sequence testing device, which includes: one or more processors; a memory; and one or more application programs, wherein the one or more application programs are stored in the memory and configured to be executed by the one or more processors to perform the transducer echo line sequence testing method described above.

[0010] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing program code, which can be called by a processor to execute the transducer echo line sequence test method described above.

[0011] The transducer echo line sequence testing method provided by this invention is applied to a transducer echo line sequence testing device, which has an echo detection state and a line sequence detection state. The transducer echo line sequence testing device includes: a device body, a transducer detection module with a detection surface, and a transducer with multiple test array elements. The method includes: when the transducer echo line sequence testing device is in the echo detection state, the detection surface is set at a first angle to the horizontal plane; the waveform data of the feedback signal obtained by reflecting the ultrasonic signals emitted by the multiple test array elements through the detection surface is compared with preset qualified data to determine the transducer performance result; when the transducer echo line sequence testing device is in the line sequence detection state, the detection surface is set at a second angle to the horizontal plane; the actual flight time difference of each adjacent test array element is determined based on the waveform data of the feedback signal obtained by reflecting the ultrasonic signals emitted by the multiple test array elements through the detection surface; and the welding correctness of each test array element is determined based on the comparison between the difference between the actual flight time difference and the theoretical flight time difference and a preset threshold. Therefore, the transducer echo line sequence testing device can perform echo detection on the ultrasonic transducer by facing the detection surface at a first angle, and it can also perform line sequence detection on the ultrasonic transducer by facing the detection surface at a second angle.

[0027] To enable those skilled in the art to better understand the embodiments of the present invention, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the embodiments of the present invention.

[0028] The application scenarios of the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] See Figure 1 and Figure 2 This invention provides a transducer echo line sequence testing device 100, which has an echo detection state and a line sequence detection state. The transducer echo line sequence testing device 100 includes a device body 11, a transducer detection module 12, and an ultrasonic transducer 13. The transducer detection module 12 is mounted on the device body 11 and has a detection surface 121. The ultrasonic transducer 13 is mounted on the device body 11. When the transducer echo line sequence testing device 100 is in the echo detection state, the detection surface 121 is set at a first angle to the horizontal plane, and the transducer detection module 12 is adapted to perform echo detection on the ultrasonic transducer 13 through the detection surface 121. When the transducer echo line sequence testing device 100 is in the line sequence detection state, the detection surface 121 is set at a second angle to the horizontal plane, and the transducer detection module 12 is adapted to perform line sequence detection on the ultrasonic transducer 13 through the detection surface 121.

[0030] Thus, the transducer echo line sequence testing device 100 can perform echo detection on the ultrasonic transducer 13 through the detection surface 121 at a first angle, and the transducer echo line sequence testing device 100 can also perform line sequence detection on the ultrasonic transducer 13 through the detection surface 121 at a second angle. This allows the transducer echo line sequence testing device 100 to integrate echo performance testing function and multi-element line sequence testing function, which helps to reduce the testing time and cost of the ultrasonic transducer 13, and also helps to enrich the functions of the transducer echo line sequence testing device 100, and better meet the testing needs of the ultrasonic transducer 13.

[0031] The first angle can be 90°, for example, the detection surface 121 is set at 90° with the horizontal plane; the second angle can be 30°~90° (excluding 90°), for example, the detection surface 121 is set at 30°, 35°, 45°, 50°, 55°, 60°, 70°, 80°, 89° or other angles with the horizontal plane, which can be set according to the actual situation.

[0032] The ultrasonic transducer 13 may include a transducer body and a cable connected together, and the ultrasonic transducer 13 is electrically connected to the transducer detection module 12 via the cable.

[0033] The detection surface 121 is a uniform and smooth plane to better reflect the ultrasonic waves from the ultrasonic transducer 13.

[0034] See Figure 2 and Figure 3In some embodiments, the main body 11 of the device includes a mounting base 111 and a transducer adjustment module 112 connected to each other. The transducer detection module 12 is mounted on the mounting base 111, and the ultrasonic transducer 13 is mounted on the transducer adjustment module 112. The transducer adjustment module 112 is adapted to move the ultrasonic transducer 13 to the transducer detection module 12 for detection.

[0035] In this way, the ultrasonic transducer 13 can be adjusted to be close to the transducer detection module 12 by the transducer adjustment module 112, so as to ensure that the ultrasonic transducer 13 can be in a suitable position, which facilitates the transducer detection module 12 to detect the ultrasonic transducer 13.

[0036] The transducer adjustment module 112 can be electrically driven to adjust the ultrasonic transducer 13, or it can be manually driven to adjust the ultrasonic transducer 13. The specific settings can be made according to the actual situation to facilitate the adjustment of the position of the ultrasonic transducer 13 by the transducer adjustment module 112.

[0037] The mounting base 111 may include a mounting base body and a support column, with the support column connected to the mounting base body. The transducer adjustment module 112 may include a support base, and the transducer adjustment module 112 is movably mounted on the support column via the support base.

[0038] In some embodiments, the transducer adjustment module 112 includes a rotating assembly 113, a moving assembly 114, and a transducer mounting assembly 115. The ultrasonic transducer 13 is mounted on the transducer mounting assembly 115, and the moving assembly 114 is connected between the rotating assembly 113 and the transducer mounting assembly 115. The rotating assembly 113 is mounted on the mounting base 111 and is adapted to rotate about a first direction X. The moving assembly 114 is adapted to move along the first direction X, or a second direction Y, or a third direction Z. The first direction X, the second direction Y, and the third direction Z are distinct.

[0039] Thus, the moving component 114 can drive the transducer mounting component 115 to move along the first direction X, the second direction Y, or the third direction Z. It can also drive the transducer mounting component 115 to rotate around the first direction X by the rotating component 113. This allows the transducer adjustment module 112 to adjust the transducer mounting component 115 in multiple directions, which helps to ensure that the transducer mounting component 115 is in a suitable angle position, thereby ensuring that the ultrasonic transducer 13 is in a suitable angle position. This helps to improve the accuracy of the transducer adjustment module 112 in adjusting the angle position of the ultrasonic transducer 13, and helps the ultrasonic transducer 13 to be more accurately placed in the detection position, which facilitates the transducer detection module 12 in detecting the ultrasonic transducer 13.

[0040] The rotating component 113 can be a turntable, and the moving component 114 is mounted on the turntable. The rotation of the turntable drives the moving component 114 and the transducer mounting component 115 to rotate around the first direction X, thereby driving the transducer to rotate.

[0041] In some embodiments, the moving component 114 includes a first moving member 1141, a second moving member 1142, and a third moving member 1143. The first moving member 1141 is connected to the rotating component 113 and the second moving member 1142, and the third moving member 1143 is connected to the second moving member 1142 and the transducer mounting component 115. The first moving member 1141 is adapted to move along a second direction Y, the second moving member 1142 is adapted to move along a third direction Z, and the third moving member 1143 is adapted to move along a first direction X.

[0042] The phrase "the first direction X, the second direction Y, and the third direction Z are distinct" means that the first direction X, the second direction Y, and the third direction Z are not the same. For example, the first direction X, the second direction Y, and the third direction Z are not set parallel to each other; they can intersect; or they can be perpendicular to each other. The specific settings can be made according to the actual situation. The following explanation uses the example where the first direction X is the length direction of the transducer echo line sequence testing device 100, the second direction Y is the height direction of the transducer echo line sequence testing device 100, and the third direction Z is the width direction of the transducer echo line sequence testing device 100, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0043] Thus, the first moving component 1141 can drive the transducer mounting assembly 115 to move along the second direction Y, the second moving component 1142 can drive the transducer mounting assembly 115 to move along the third direction Z, and the third moving component 1143 can drive the transducer mounting assembly 115 to move along the first direction X, so that the transducer mounting assembly 115 can move in multiple directions to ensure that the ultrasonic transducer 13 on the transducer mounting assembly 115 can be in a suitable position, so as to facilitate the transducer detection module 12 to detect the ultrasonic transducer 13.

[0044] The movement between the rotating assembly 113, the first moving part 1141, the second moving part 1142 and the third moving part 1143 is achieved by the cooperation of slide rails and slide grooves, which can be set according to the actual situation.

[0045] See Figures 4 to 6 In some embodiments, the transducer mounting assembly 115 includes a fixing member 1151, which is provided with a first limiting portion 1152 and a second limiting portion 1153, and the ultrasonic transducer 13 is limited between the first limiting portion 1152 and the second limiting portion 1153.

[0046] Thus, the first limiting part 1152 and the second limiting part 1153 can position the ultrasonic transducer 13, which helps to improve the accuracy of the ultrasonic transducer 13 being installed on the fixing member 1151 and improves the efficiency of the ultrasonic transducer 13 being installed on the fixing member 1151. The first limiting part 1152 and the second limiting part 1153 also help to limit the ultrasonic transducer 13, which helps to reduce the possibility of the ultrasonic transducer 13 falling off the fixing member 1151.

[0047] In some embodiments, the transducer mounting assembly 115 includes a pressing member 1154, which includes a pressing body 1155 and a flexible pressing part 1156. The flexible pressing part 1156 protrudes from the pressing body 1155, and the pressing body 1155 avoids the first limiting part 1152 and the second limiting part 1153. The flexible pressing part 1156 presses against the ultrasonic transducer 13.

[0048] Thus, the flexible pressing part 1156 can press the ultrasonic transducer 13 into the space formed by the first limiting part 1152 and the second limiting part 1153. The pressing part 1154 and the fixing part 1151 cooperate to fix the ultrasonic transducer 13 to the fixing part 1151, which helps to reduce the possibility of the ultrasonic transducer 13 falling off the fixing part 1151. In addition, the pressing body 1155 avoids the first limiting part 1152 and the second limiting part 1153. The pressing body 1155 will not hinder the connection between the pressing part 1154 and the fixing part 1151. It also helps to increase the contact area between the pressing part 1154 and the fixing part 1151 and improve the tightness of the connection between the pressing part 1154 and the fixing part 1151, thereby better reducing the possibility of the ultrasonic transducer 13 falling off the fixing part 1151.

[0049] In addition, the flexible pressing part 1156 can buffer the pressure of the transducer, further protect the ultrasonic transducer 13, help reduce the damage caused by excessive pressure on the ultrasonic transducer 13, and extend the service life of the ultrasonic transducer 13.

[0050] The flexible pressing part 1156 can be made of 50-60HA silicone, Pebax or other materials, and the specific material can be set according to the actual situation.

[0051] Revisit Figure 1 and Figure 2 In some embodiments, the transducer detection module 12 includes a detection component 124 and a signal transmission component 125. The detection component 124 is mounted on the mounting base 111, and the signal transmission component 125 is located outside the mounting base 111 and electrically connected to the detection component 124 and the ultrasonic transducer 13.

[0052] In some implementations, the signal transmission components include a host computer, a pulse receiver, a gating module, and an oscilloscope. Detailed descriptions of the host computer, pulse receiver, gating module, and oscilloscope will follow, and will not be repeated here.

[0053] This helps to reduce signal interference between the detection component 124 and the signal transmission component 125 caused by the integration of the detection component 124 and the signal transmission component 125 in the mounting base 111, which would affect the performance of the detection component 124. It also helps to reduce the direct transfer of heat generated by the signal transmission component 125 to the detection component 124, which would affect the performance of the detection component 124.

[0054] The ultrasonic transducer 13 is electrically connected to the signal transmission component 125 via a cable.

[0055] In some embodiments, the detection component 124 includes a water tank 122 and a reflective component 123, the water tank 122 being mounted on a mounting base 111, the reflective component 123 being mounted on the water tank 122, and the reflective component 123 having a detection surface 121.

[0056] Thus, the transducer echo sequence testing device 100 can reflect the ultrasonic waves emitted by multiple array elements of the ultrasonic transducer 13 through the reflection component 123. The ultrasonic transducer 13 can convert the reflected ultrasonic waves into electrical signals and transmit them to the signal transmission component 125. The signal transmission component 125 can collect the ultrasonic wave information emitted by multiple array elements of the ultrasonic transducer 13 and perform data analysis to test the electrical and acoustic performance of the ultrasonic transducer 13. The water tank 122 can simulate the actual working environment of the ultrasonic transducer 13, which helps to ensure the performance of the ultrasonic transducer 13 under real conditions. Moreover, the water in the water tank 122 is a homogeneous and controllable medium that can provide consistent sound velocity and propagation characteristics. In a homogeneous medium, the propagation path and reflection characteristics of sound waves or electromagnetic waves are easier to predict and control, thereby improving the accuracy of the ultrasonic transducer 13 test.

[0057] The water tank 122 is a transparent box to facilitate observation of the various components inside the water tank 122; the reflective component 123 can be glued to the water tank 122 with waterproof adhesive, and the specific configuration can be set according to the actual situation.

[0058] See Figure 2 and Figure 7In some embodiments, the reflective assembly 123 includes a first reflective body 1231 and a second reflective body 1232 connected to each other. The first reflective body 1231 and the second reflective body 1232 each have a detection surface 121. The first reflective body 1231 is set at a first angle to the horizontal plane, so that when the transducer echo line sequence testing device 100 is in the echo detection state, the detection surface 121 is set at a first angle to the horizontal plane; the second reflective body 1232 is set at a second angle to the horizontal plane, so that when the transducer echo line sequence testing device 100 is in the line sequence detection state, the detection surface 121 is set at a second angle to the horizontal plane.

[0059] Thus, the reflective component 123 can integrate a first reflective body 1231 and a second reflective body 1232, so that the transducer detection module 12 can perform echo detection on the ultrasonic transducer 13 through the reflection surface of the first reflector, and can also perform line sequence detection on the ultrasonic transducer 13 through the reflection surface of the second reflector. This helps to enrich the functions of the transducer echo line sequence testing device 100 and better meet the testing needs of the ultrasonic transducer 13.

[0060] In addition, the structure of the reflective component 123 is simple, which facilitates the manufacturing of the reflective component 123 and saves manufacturing costs.

[0061] For example, when the ultrasonic transducer 13 needs to perform echo detection, the ultrasonic transducer 13 can be moved to a position close to the first reflective body 1231. At this time, the ultrasonic transducer 13 is opposite to the detection surface 121 of the first reflective body 1231, which facilitates the echo detection of the ultrasonic transducer 13.

[0062] For example, when the ultrasonic transducer 13 needs to be inspected for line sequence, the ultrasonic transducer 13 can be moved to a position close to the second reflector 1232. At this time, the ultrasonic transducer 13 is opposite to the detection surface 121 of the second reflector 1232, which facilitates the inspection of the ultrasonic transducer 13 for line sequence.

[0063] The first reflective body 1231 can be set at 90° to the horizontal plane, for example, the first reflective body 1231 is set at 90° to the horizontal plane; the second reflective body 1232 can be set at 30° to 90° (excluding 90°) to the horizontal plane, for example, the second reflective body 1232 is set at 30°, 35°, 45°, 50°, 55°, 60°, 70°, 80°, 89° or other angles to the horizontal plane, and the specific setting can be made according to the actual situation.

[0064] In some embodiments, the detection component 124 further includes a first mode sensor 1241, a second mode sensor 1242, and a position sensor 1243. The first mode sensor 1241, the second mode sensor 1242, and the position sensor 1243 are all installed in the water tank 122 and electrically connected to the signal transmission component 125 respectively. The first mode sensor 1241 is positioned closer to the first reflector 1231 relative to the second mode sensor 1242. The second mode sensor 1242 is positioned closer to the first reflector 1231 relative to the first mode sensor 1241. The position sensor 1243 is positioned closer to the ultrasonic transducer 13 relative to the first mode sensor 1241 and the second mode sensor 1242.

[0065] Thus, the position sensor 1243 can detect the position of the ultrasonic transducer 13. The first mode sensor 1241 and the second mode sensor 1242 can cooperate with the position sensor 1243 to better detect the position of the ultrasonic transducer 13. This makes it easier for the signal transmission component 125 to determine which working mode the transducer echo sequence testing device 100 belongs to based on the position of the ultrasonic transducer 13, and to activate the corresponding test procedure, thereby improving the accuracy of the transducer echo sequence testing device 100.

[0066] In addition, when the transducer echo sequence testing device 100 is in the echo detection state, the position sensor 1243 can also determine whether the position of the ultrasonic transducer 13 in the water tank 122 is parallel to the detection surface 121, so as to ensure that the ultrasonic waves of the ultrasonic transducer 13 can be reflected at a predetermined angle, thereby improving the accuracy of the detection.

[0067] Among them, the first mode sensor 1241, the second mode sensor 1242 and the position sensor 1243 can be waterproof infrared sensors, waterproof ultrasonic sensors and other sensors, and the specific settings can be made according to the actual situation.

[0068] See Figures 8 to 10 In some embodiments, the reflective assembly 123 includes a reflector 1233 and an adjusting member 1234 connected together. The reflector 1233 has a detection surface 121, and the adjusting member 1234 is adapted to adjust the angle between the reflector 1233 and the horizontal plane, so that when the transducer echo sequence testing device 100 is in the echo detection state, the detection surface 121 is set at a first angle with the horizontal plane, such as... Figure 8 As shown; when the transducer echo line sequence testing device 100 is in the line sequence detection state, the detection surface 121 is set at a second angle to the horizontal plane, such as... Figure 9 As shown.

[0069] In this way, the angle between the reflector 1233 and the horizontal plane can be adjusted by the adjusting member 1234, which helps to improve the flexibility of the adjustment of the reflector 1233. It also allows the detection surface 121 to be set at different angles with the horizontal plane, which is convenient for different detection states of the transducer echo line sequence testing device 100. The detection component 124 does not need to be set separately with the first mode sensor 1241, the second mode sensor 1242 and the position sensor 1243 to detect the position of the ultrasonic transducer 13, which helps to simplify the structure of the detection component 124, facilitate manufacturing and save manufacturing costs.

[0070] Furthermore, adjusting the angle between the reflector 1233 and the horizontal plane by adjusting the adjustment member 1234 helps to reduce the movement of the transducer adjustment module 112 in the first direction X, which helps to reduce the frequent adjustments caused by the movement of the transducer adjustment module 112, making the operation more efficient.

[0071] For example, such as Figure 8 As shown, when the ultrasonic transducer 13 needs to perform echo detection, the angle between the reflector 1233 and the horizontal plane can be adjusted so that the detection surface 121 is set at a first angle with the horizontal plane. At this time, the ultrasonic transducer 13 is opposite to the detection surface 121, which facilitates the echo detection of the ultrasonic transducer 13.

[0072] For example, such as Figure 9 As shown, when the ultrasonic transducer 13 needs to perform line sequence detection, the angle between the reflector 1233 and the horizontal plane can be adjusted so that the detection surface 121 is set at a second angle with the horizontal plane. At this time, the ultrasonic transducer 13 is opposite to the detection surface 121, which facilitates the line sequence detection of the ultrasonic transducer 13.

[0073] The adjusting component 1234 adjusts the angle between the reflector 1233 and the horizontal plane within the range of 30° to 90°. For example, the adjusting component 1234 can adjust the reflector 1233 to be set at a first angle to the horizontal plane, such as 90°. Alternatively, the adjusting component 1234 can adjust the reflector 1233 to be set at a second angle to the horizontal plane, such as 30° to 90° (excluding 90°). For example, the reflector 1233 can be set at 30°, 35°, 45°, 50°, 55°, 60°, 70°, 80°, 89°, or other angles with the horizontal plane. The specific angle can be set according to the actual situation.

[0074] In some embodiments, the adjusting member 1234 includes a mounting housing 1235, an operating body 1236, and a linkage body 1237. The operating body 1236 is movably mounted on the mounting housing 1235. One end of the linkage body 1237 is connected to the operating body 1236, and the other end of the linkage body 1237 is connected to the side of the reflector 1233 away from the detection surface 121. One end of the reflector 1233 is rotatably connected to the mounting housing 1235. The movement of the operating body 1236 relative to the mounting housing 1235 is adapted to drive the linkage body 1237 to move synchronously relative to the mounting housing 1235, so that the reflector 1233 rotates relative to the mounting housing 1235.

[0075] In this way, the actuator 1236 can operate the linkage 1237 relative to the mounting shell 1235, thereby causing the reflector 1233 to rotate relative to the mounting shell 1235. This achieves linkage between the reflector 1233 and the actuator 1236 and linkage 1237, facilitating angle adjustment of the reflector 1233. The linkage between the actuator 1236, linkage 1237, and reflector 1233 is simple and convenient for manufacturing the reflective assembly 123.

[0076] The operating body 1236 may include a connected knob and a screw. Rotating the knob causes the screw to move relative to the mounting housing 1235. The linkage body 1237 may include a connected slider and a support rod. The slider is sleeved on the outer periphery of the screw. One end of the support rod is connected to the slider, and the other end of the support rod is connected to the reflector 1233. The movement of the screw relative to the mounting housing 1235 synchronously causes the slider to move relative to the mounting housing 1235, and then the support rod causes the reflector 1233 to rotate relative to the mounting housing 1235.

[0077] In this way, the adjusting component 1234 can form a slider rocker mechanism, and the threaded engagement between the screw and the slider gives the slider rocker mechanism a self-locking function, thereby facilitating the adjustment of the angle between the detection surface of the reflector 1233 and the horizontal plane.

[0078] Since the screw of the operating body 1236 needs to extend beyond the outside of the water tank 122, an opening needs to be provided on the water tank 122 to allow the screw to extend. A sealing waterproof ring can be provided at the opening to improve the sealing between the operating body 1236 and the water tank 122. The sealing waterproof ring is a ring and can be interference-fitted with the screw.

[0079] In some embodiments, the detection component 124 further includes an angle sensor 1244, which is mounted on the water tank 122 and electrically connected to the signal transmission component 125.

[0080] Thus, the angle sensor 1244 can detect the angle between the detection surface 121 and the horizontal plane, and the signal transmission component 125 receives the angle signal from the angle sensor 1244 and performs data analysis to realize the line sequence detection of the ultrasonic transducer 13.

[0081] In summary, the transducer echo line sequence testing device 100 provided in this embodiment of the invention has an echo detection state and a line sequence detection state. The transducer detection module 12 of the transducer echo line sequence testing device 100 is installed on the device body 11, and the transducer detection module 12 has a detection surface 121. An ultrasonic transducer 13 is installed on the device body 11. When the transducer echo line sequence testing device 100 is in the echo detection state, the detection surface 121 is set at a first angle to the horizontal plane, and the transducer detection module 12 is adapted to perform echo detection on the ultrasonic transducer 13 through the detection surface 121. When the transducer echo line sequence testing device 100 is in the line sequence detection state, the detection surface 121 is set at a second angle to the horizontal plane, and the transducer detection module 12 is adapted to perform line sequence detection on the ultrasonic transducer 13 through the detection surface 121. Thus, the transducer echo line sequence testing device 100 can perform echo detection on the ultrasonic transducer 13 through the detection surface 121 at a first angle, and the transducer echo line sequence testing device 100 can also perform line sequence detection on the ultrasonic transducer 13 through the detection surface 121 at a second angle. This allows the transducer echo line sequence testing device 100 to integrate echo performance testing function and multi-element line sequence testing function, which helps to reduce the testing time and cost of the ultrasonic transducer 13, and also helps to enrich the functions of the transducer echo line sequence testing device 100, and better meet the testing needs of the ultrasonic transducer 13.

[0082] Please see Figure 11 , Figure 11 This is a flowchart illustrating a transducer echo line sequence testing method provided in an embodiment of this application, which can be applied to the aforementioned transducer echo line sequence testing device. As shown in Figure N, the method may include steps 210 to 220.

[0083] In step 210, when the transducer echo sequence test device is in the echo detection state, the detection surface is set at a first angle to the horizontal plane. The waveform data of the feedback signal obtained by reflecting the ultrasonic signals emitted by multiple test array elements through the detection surface is compared with the preset qualified data to determine the performance result of the transducer.

[0084] In some implementations, when the transducer echo sequence test device is in echo detection mode, the performance of the transducer can be tested.

[0085] In some embodiments, the transducer detection module further includes a first mode sensor and a position sensor. The transducer echo sequence testing method may also include: when the first mode sensor detects that the transducer echo sequence testing device is in echo detection mode, and the position sensor detects that the detection surface is at a first angle to the horizontal plane, the transducer echo sequence testing device is determined to be in echo detection state.

[0086] In some implementations, the first mode sensor may be a mode sensor.

[0087] In some implementations, the echo detection mode can be a mode for detecting the performance of the transducer.

[0088] In some embodiments, the first angle can be 90° between the detection surface and the horizontal plane. It is understood that this application is not limited to the first angle being 90°.

[0089] In some implementations, the first waveform data corresponding to the multiple test array elements is the first waveform data obtained after the multiple test array elements simultaneously emit ultrasonic waves, and these ultrasonic waves undergo specular reflection from the detection surface, and the reflected ultrasonic waves are converted into the first waveform corresponding to the electrical signal by the transducer.

[0090] In some implementations, the first waveform data may include at least one or more of the center frequency value, bandwidth value, and peak-to-peak value.

[0091] In embodiments of this application, the first waveform data may include a center frequency value, a bandwidth value, and a peak-to-peak value.

[0092] In some implementations, the preset pass data can be pre-set data. The preset pass data can reflect whether the transducer's performance is qualified. For example, when the waveform data equals the preset pass data, the transducer's performance is determined to be qualified. Conversely, when the waveform data does not equal the preset pass data, the transducer's performance is determined to be unqualified.

[0093] After multiple test array elements emit ultrasonic signals, the ultrasonic signals are emitted through a detection surface at a 90° angle to the horizontal plane. The first waveform data corresponding to the feedback signals obtained from these emitted ultrasonic signals is compared with preset qualified data to determine the transducer's performance. Specifically, in some embodiments, please refer to... Figure 12 , Figure 12 This is a schematic diagram of the structure of a transducer detection module provided in an embodiment of this application, as shown below. Figure 12 As shown, the transducer testing module 300 includes a host computer 310, a pulse receiver 320, a gating module 330, and an oscilloscope 340. The transducer echo line sequence testing method further includes the following steps: (1) When the host computer 310 determines that the current state is the echo detection state, it drives the pulse receiver 320 to send a pulse signal to the gating module 330; (2) The gating module 330 switches sequentially in the channels corresponding to the multiple test array elements according to the pulse signal, and sends an excitation signal to the test array element corresponding to the switched channel through the switched channel, so that the multiple test array elements emit ultrasonic signals at the same time, and the ultrasonic signal is transmitted through the detection surface to obtain a feedback signal; (3) The gating module 330 switches sequentially in the channels corresponding to the multiple test array elements to receive the feedback signals transmitted by the multiple test array elements and transmit the feedback signals corresponding to the multiple test array elements to the pulse receiver 320. (4) The oscilloscope 340 collects multiple first waveform data corresponding to multiple test array elements transmitted from the pulse receiver 320, and transmits the multiple first waveform data to the host computer 310; (5) The host computer 310 compares the first waveform data with the preset qualified data to determine whether the transducer's performance is qualified.

[0094] In some implementations, when the first mode sensor detects that the transducer is in echo detection mode and the position sensor detects that the detection surface is at a first angle to the horizontal plane, the host computer 310 determines that the current state is echo detection state.

[0095] In some implementations, the gating module 330 can be a multiple-to-one electrical signal gating module.

[0096] In some implementations, the host computer 310 is connected to the pulse receiver 320, the gating module 330, and the oscilloscope 340, respectively. Through the connection between the host computer 310 and the gating module 330, the host computer 310 can send control signals to the gating module 330, causing the gating module 330 to switch the connection channels with multiple test array elements under the action of the first control signal. For example, under the action of the first control signal, the gating module 330 switches the connection channel with the transducer from channel a corresponding to test array element A to channel b corresponding to test array element B.

[0097] Through the connection between the host computer 310 and the pulse receiver 320, the host computer 310 can send a second control signal to the pulse receiver 320, causing the pulse receiver 320 to transmit a pulse signal to the gating module 330 under the action of the second control signal. For example, when the transducer echo line sequence testing device is in echo detection state or line sequence detection state, it sends a second control signal to the pulse receiver 320, causing the pulse receiver 320 to transmit a pulse signal to the gating module 330 under the action of the second control signal.

[0098] By connecting the host computer 310 to the oscilloscope 340, the host computer 310 can receive waveforms from multiple test array elements collected by the oscilloscope 340, thereby determining waveform data based on the waveforms of the multiple test array elements, and further determining the performance of the transducer based on the waveform data.

[0099] In some embodiments, the pulse receiver 320 is connected to both the gating module 330 and the oscilloscope 340. The pulse receiver 320 can be used to transmit pulse signals to the gating module 330 under the influence of a second control signal, causing the gating module 330 to receive signals corresponding to the waveforms of multiple test elements and transmit these signals to the pulse receiver 320. The pulse receiver 320 then transmits the signals to the oscilloscope 340, allowing the oscilloscope 340 to collect the waveforms of the multiple test elements.

[0100] In other words, the signal transmission path is: host computer 310 — pulse receiver 320 — gating module 330 — multiple test array elements — gating module 330 — pulse receiver 320 — oscilloscope 340 — host computer 310. Feedback signals corresponding to multiple test array elements are collected through this signal transmission path, i.e., multiple feedback signals. After collecting multiple feedback signals, that is, after collecting information from all test array elements, the host computer 310 extracts waveform data from the multiple feedback signals.

[0101] For example, after transmitting the feedback signal of test array element A to pulse receiver 320, gating module 330, under the control of host computer 310, switches the connection channel between test array element A and gating module 330 to the connection channel between the next test array element B and gating module 330, so as to receive the feedback signal transmitted by test array element B.

[0102] Among them, the waveform data extracted from multiple feedback signals are time-domain waveform data. The host computer 310 transforms the time-domain waveform data into frequency-domain waveform data to calculate the center frequency value, bandwidth value, and peak-to-peak value based on the frequency-domain waveform data. The host computer 310 then compares the center frequency value, bandwidth value, and peak-to-peak value with preset qualified data to determine the performance of the transducer.

[0103] In step 220, when the transducer echo line sequence testing device is in the line sequence detection state, the detection surface is set at a second angle to the horizontal plane. The actual flight time difference between each adjacent test element is determined based on the waveform data of the feedback signal obtained by the ultrasonic signal emitted by multiple test elements after being reflected by the detection surface. The welding of each test element is determined based on the comparison between the difference between the actual flight time difference and the theoretical flight time difference and the preset threshold.

[0104] In some implementations, the transducer echo line sequence testing device is in line sequence detection mode, used to detect whether each test array element is arranged in a linear sequence, thereby determining whether each test array element is soldered incorrectly, or identifying the test array element with soldering errors among multiple test array elements. This eliminates the need to use devices such as voltage converters to individually check whether the test array elements are soldered correctly, thus improving the efficiency of determining the soldering correctness of multiple test array elements.

[0105] In some implementations, the second angle is an acute angle. In some implementations, the difference between the first angle and the second angle is an acute angle.

[0106] In some implementations, the waveform data corresponding to the multiple test array elements are waveform data obtained after the multiple test array elements simultaneously emit ultrasonic waves, and these ultrasonic waves undergo specular reflection from the detection surface, and the reflected ultrasonic waves are converted into waveforms corresponding to electrical signals by the transducer.

[0107] In some implementations, the preset threshold can be pre-set. In some implementations, the preset threshold can be determined based on the difference between theoretical flight time and actual flight time.

[0108] The ultrasonic signals emitted by multiple test array elements are reflected by a detection surface at a second angle to the horizontal plane. Feedback signals corresponding to these ultrasonic signals are obtained. The actual flight time difference between adjacent test array elements is determined based on the second waveform data of these feedback signals. Furthermore, the difference between the actual flight time difference and the theoretical flight time difference is compared with a preset threshold to determine whether the welding of each adjacent test array element is correct. Specifically: In some implementations, please refer to Figure 13 , Figure 13 This is a schematic diagram of another transducer detection module provided in an embodiment of this application, as shown below. Figure 13 As shown, the transducer testing module includes a host computer 310, a pulse receiver 320, a gating module 330, and an oscilloscope 340. The transducer echo line sequence testing method may further include the following steps: (1) When the host computer 310 determines that the current state is the line sequence detection state, it drives the pulse receiver 320 to send a pulse signal to the gating module 330; (2) The gating module 330 switches sequentially in the channels corresponding to the multiple test array elements according to the pulse signal, and sends an excitation signal to the test array element corresponding to the switched channel through the switched channel, so that the multiple test array elements emit ultrasonic signals, and the ultrasonic signals are transmitted through the detection surface to obtain feedback signals. (3) The gating module 330 switches sequentially in the channels corresponding to the multiple test array elements to receive the feedback signals transmitted by the multiple test array elements and transmit the feedback signals corresponding to the multiple test array elements to the pulse receiver 320. (4) The oscilloscope 340 collects multiple second waveforms corresponding to multiple test array elements transmitted from the pulse receiver 320, and transmits the multiple second waveforms to the host computer 310; (5) The host computer 310 determines the actual flight time difference of each test element in the multiple test elements based on the first valid echo position of the second waveform data of the multiple second waveforms.

[0109] Similarly, the signal transmission path is as follows: host computer 310 — pulse receiver 320 — gating module 330 — multiple test array elements — gating module 330 — pulse receiver 320 — oscilloscope 340 — host computer 310. Feedback signals corresponding to multiple test array elements are acquired through this signal transmission path, i.e., multiple feedback signals. The specific process can be referred to the above description and will not be repeated here.

[0110] After collecting multiple feedback signals, i.e., after collecting all the information of the test array elements, the host computer 310 determines the actual flight time difference of each adjacent test array element based on the first valid echo position in the multiple second waveform data corresponding to the multiple feedback signals.

[0111] After determining the actual flight time difference between each adjacent test array element in the multiple test array elements, the host computer 310 compares the difference between the actual flight time difference between each adjacent test array element in the multiple test array elements and the theoretical flight time difference between each adjacent test array element in the multiple test array elements with a preset threshold to determine the actual flight time difference between each adjacent test array element in the multiple test array elements.

[0112] For example, the multiple test array elements include test array element A and test array element B arranged adjacent to test array element A. The host computer 310 determines the peak time (i.e., TOP value) corresponding to test array element A based on the first valid echo position of the second waveform data corresponding to test array element A; the host computer 310 determines the peak time corresponding to test array element B based on the first valid echo position of the second waveform data corresponding to test array element B; the host computer 310 determines the actual flight time difference between test array element A and test array element B based on the difference between the peak time corresponding to test array element A and the peak time corresponding to test array element B. This process is repeated to obtain the actual flight time difference between each test array element in the multiple test array elements.

[0113] For example, the multiple test array elements include test array element A and test array element B arranged adjacent to test array element A. The host computer 310 compares the difference between the actual flight time difference between test array element A and test array element B with the difference between the theoretical flight time difference between test array element A and test array element B to determine whether test array element A conforms to a linear arrangement, thereby determining whether test array element A has been soldered incorrectly.

[0114] The theoretical flight time difference can be preset, and the theoretical flight time difference between each test element in multiple test arrays can be determined in the following manner. Specifically, the transducer echo line sequence test method may also include the following steps: (1) Determine the acoustic path difference between each adjacent test element in the multiple test elements based on the spacing between adjacent test elements and the second angle.

[0115] (2) Determine the theoretical flight time difference between each adjacent test array element based on the sound path difference and sound speed.

[0116] The host computer determines the theoretical flight time difference between adjacent test array elements based on the sound path difference and sound speed between each adjacent test array element.

[0117] The host computer can obtain the theoretical flight time difference between each adjacent test array element using the following formula, specifically: .

[0118] in," "This represents the theoretical flight time difference between each adjacent test array element;" "This represents the spacing between adjacent test elements;" "This is the second perspective."

[0119] After obtaining the acoustic path difference between each adjacent test array element using the above method, the theoretical flight time difference between each adjacent test array element is determined based on the acoustic path difference and the sound speed. This can be determined using the following expression: in," "This represents the theoretical flight time difference between each adjacent test array element;" "Speed ​​of sound"

[0120] The theoretical flight time difference between each adjacent test array element is obtained through the above method. The difference between the theoretical flight time difference and its corresponding actual flight time difference between each adjacent test array element is compared with a preset threshold to determine whether the welding of the test array elements is correct. Specifically: In some implementations, the transducer echo line sequence test method may include the step of: if the difference between the theoretical flight time difference and the actual flight time difference corresponding to the target test array element pair is less than or equal to a preset threshold, then it is determined that the test array elements included in the target test array element are correctly welded.

[0121] The target test element is any adjacent test element among multiple test elements.

[0122] For example, the target test element pair includes test element A and test element B arranged adjacent to test element A. The theoretical time-of-flight difference between test element A and test element B is "". The actual flight time difference between test element A and test element B is " The preset threshold is " ",like If the test array element A and test array element B are correctly welded, then the test array element A and test array element B are correctly welded.

[0123] In some implementations, the preset threshold is related to the difference between the theoretical flight time difference and the actual flight time difference for each adjacent test element in the plurality of test elements. That is, the host computer can set a relatively suitable value as the preset value based on the theoretical flight time difference and the actual flight time difference to tolerate the effects of unavoidable interference. For example, the effects of placement errors, dielectric disturbances, oscilloscope sampling errors, reflection deformation, etc.

[0124] In one specific implementation, the preset threshold can be the difference between the theoretical flight time difference and the actual flight time difference, i.e. .

[0125] By using a preset threshold as the boundary condition for determining linearity, the correct welding of each test element in a multi-test array can be determined in the manner described above. This eliminates the need to inspect each test element individually, thus improving inspection efficiency.

[0126] By determining the actual flight time difference between each adjacent test array element in multiple test array elements, and the corresponding theoretical flight time difference, if the difference between the actual flight time difference and the theoretical flight time difference is less than or equal to a preset threshold, it is determined that these test array elements are all correctly welded.

[0127] In some implementations, the transducer echo line sequence testing method may include the step of: if the difference between the theoretical flight time difference and the actual flight time difference corresponding to the target test array element pair is greater than a preset threshold, then it is determined that the test array elements included in the target test array element are incorrectly welded.

[0128] This application determines whether a test element is correctly soldered by comparing the difference between the actual flight time difference and the theoretical flight time difference between the test element and its adjacent test elements with a preset threshold. This allows for efficient testing without the need for individual testing of each test element using devices such as voltmeters, achieving the desired test efficiency through a transducer echo sequence testing device.

The second execution module 420 is used to determine the actual flight time difference between each adjacent test array element in the multiple test array elements based on the waveform data of the feedback signal obtained by the ultrasonic signal emitted by multiple test array elements after being reflected by the test surface when the transducer echo line sequence test device is in the line sequence detection state, the detection surface is set at a second angle with the horizontal plane, and the welding of each test array element is determined based on the comparison relationship between the difference between the actual flight time difference and the theoretical flight time difference and the preset threshold.
