[0029] Referring to Figure 1 and Figure 2 The present embodiment provides a transducer echo line sequence test device 100, the transducer echo line sequence test device 100 has an echo detection state and a line sequence detection state, the transducer echo line sequence test device 100 includes a device main body 11, a transducer detection module 12 and an ultrasonic transducer 13, the transducer detection module 12 is installed on the device main body 11, the transducer detection module 12 has a detection surface 121; the ultrasonic transducer 13 is installed on the device main body 11. Wherein, when the transducer echo line sequence test device 100 is in the echo detection state, the detection surface 121 is arranged at a first angle with the horizontal plane, and the transducer detection module 12 is adapted to detect the echo of the ultrasonic transducer 13 through the detection surface 121; when the transducer echo line sequence test device 100 is in the line sequence detection state, the detection surface 121 is arranged at a second angle with the horizontal plane, and the transducer detection module 12 is adapted to detect the line sequence of the ultrasonic transducer 13 through the detection surface 121.

[0030] In this way, the transducer echo line sequence test device 100 can detect the echo of the ultrasonic transducer 13 through the detection surface 121 at the first angle, and the transducer echo line sequence test device 100 can also detect the line sequence of the ultrasonic transducer 13 through the detection surface 121 at the second angle, so that the transducer echo line sequence test device 100 can integrate the echo performance detection function and the multi-element line sequence detection function, which helps to reduce the time and cost of detecting the ultrasonic transducer 13, and also helps to enrich the functions of the transducer echo line sequence test device 100, and better meet the detection needs of the ultrasonic transducer 13.

[0031] Wherein, the first angle can be 90°, for example, the detection surface 121 is arranged at 90° with the horizontal plane; the second angle can be 30°-90° (not included), for example, the detection surface 121 is arranged at 30°, 35°, 45°, 50°, 55°, 60°, 70°, 80°, 89° or other angles with the horizontal plane, which can be set according to actual conditions.

[0032] Wherein, the ultrasonic transducer 13 can include a transducer main body and a cable connected thereto, and the ultrasonic transducer 13 is electrically connected to the transducer detection module 12 through the cable.

[0033] Wherein, the detection surface 121 is a uniform and smooth plane, so as to better reflect the ultrasonic waves of the ultrasonic transducer 13.

[0035] In this way, the ultrasonic transducer 13 can be adjusted by the transducer adjusting module 112 to be close to the transducer detecting module 12, so as to ensure that the ultrasonic transducer 13 can be in a suitable position, facilitating the detection of the ultrasonic transducer 13 by the transducer detecting module 12.

[0036] The transducer adjusting module 112 can be electrically driven to adjust the ultrasonic transducer 13, or can be manually driven to adjust the ultrasonic transducer 13, which can be set according to actual conditions, so as to facilitate the adjustment of the position of the ultrasonic transducer 13 by the transducer adjusting module 112.

[0037] The mounting seat 111 can comprise a mounting seat body and a support column connected to the mounting seat body, and the transducer adjusting module 112 can comprise a support seat, which is movably mounted on the support column by the support seat.

[0038] In some embodiments, the transducer adjusting module 112 comprises 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, 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 seat 111 and adapted to rotate around a first direction X, and the moving assembly 114 is adapted to move along the first direction X, a second direction Y or a third direction Z; wherein the first direction X, the second direction Y and the third direction Z are different.

[0039] In this way, the moving assembly 114 can drive the transducer mounting assembly 115 to move along the first direction X, the second direction Y or the third direction Z, or the rotating assembly 113 can drive the transducer mounting assembly 115 to flip around the first direction X, so that the transducer adjusting module 112 can adjust the transducer mounting assembly 115 in multiple directions, which helps to ensure that the transducer mounting assembly 115 is in a suitable angle position, and further ensures that the ultrasonic transducer 13 is in a suitable angle position, which helps to improve the accuracy of the transducer adjusting module 112 in adjusting the angle position of the ultrasonic transducer 13, and helps the ultrasonic transducer 13 to be more accurately in the detection position, facilitating the detection of the ultrasonic transducer 13 by the transducer detecting module 12.

[0040] The rotating assembly 113 can be a rotating table. The moving assembly 114 is mounted on the rotating table. The rotating table drives the moving assembly 114 and the transducer mounting assembly 115 to rotate around the first direction X, so as to drive the transducer to rotate.

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

[0042] The first direction X, the second direction Y, and the third direction Z are different, for example, the first direction X, the second direction Y, and the third direction Z are not parallel. The first direction X, the second direction Y, and the third direction Z can intersect each other. The first direction X, the second direction Y, and the third direction Z can be perpendicular to each other. The specific arrangement can be determined according to actual conditions. In the following description, 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. The third direction Z is the width direction of the transducer echo line sequence testing device 100. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0043] In this way, the first moving part 1141 can drive the transducer mounting assembly 115 to move along the second direction Y. The second moving part 1142 can drive the transducer mounting assembly 115 to move along the third direction Z. The third moving part 1143 can drive the transducer mounting assembly 115 to move along the first direction X. The transducer mounting assembly 115 can move in multiple directions to ensure that the ultrasonic transducer 13 on the transducer mounting assembly 115 is in a suitable position, facilitating the detection of the ultrasonic transducer 13 by the transducer detection module 12.

[0044] The moving modes between the rotating assembly 113, the first moving part 1141, the second moving part 1142, and the third moving part 1143 are the cooperation of sliding rails and sliding grooves. The specific arrangement can be determined according to actual conditions.

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

[0046] In this way, the first limiting part 1152 and the second limiting part 1153 can position the mounting position of the ultrasonic transducer 13, help to improve the accuracy of the ultrasonic transducer 13 mounted on the fixing part 1151, help to improve the efficiency of the ultrasonic transducer 13 mounted on the fixing part 1151, and the first limiting part 1152 and the second limiting part 1153 also help to limit the ultrasonic transducer 13 and help to reduce the situation that the ultrasonic transducer 13 falls off from the fixing part 1151.

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

[0048] In this way, the flexible pressing part 1156 can press the ultrasonic transducer 13 in the space formed by the first limiting part 1152 and the second limiting part 1153, and the pressing part 1154 cooperates with the fixing part 1151 to fix the ultrasonic transducer 13 on the fixing part 1151, which helps to reduce the situation that the ultrasonic transducer 13 falls off from the fixing part 1151, and the pressing body 1155 avoids the first limiting part 1152 and the second limiting part 1153, so that the pressing body 1155 will not hinder the connection between the pressing part 1154 and the fixing part 1151, and also helps to increase the contact area between the pressing part 1154 and the fixing part 1151, improve the tightness of the connection between the pressing part 1154 and the fixing part 1151, and thus better reduce the situation that the ultrasonic transducer 13 falls off from the fixing part 1151.

[0049] In addition, the flexible pressing part 1156 can provide pressure buffering for the transducer, further protect the ultrasonic transducer 13, help to reduce the situation that the ultrasonic transducer 13 is damaged due to excessive pressure, and prolong the service life of the ultrasonic transducer 13.

[0050] In some embodiments, the flexible pressing part 1156 can be made of 50-60HA silicone, pebax or other materials, which can be set according to actual conditions.

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

[0052] In some embodiments, the signal transmission assembly comprises a host computer, a pulse receiver, a gating module and an oscilloscope. Detailed descriptions of the host computer, the pulse receiver, the gating module and the oscilloscope are provided in the following description, which will not be repeated here.

[0053] In this way, it helps to reduce the situation that the detection assembly 124 and the signal transmission assembly 125 are integrated in the mounting base 111, which causes signal interference of the detection assembly 124 and the signal transmission assembly 125, affects the performance of the detection assembly 124, and also helps to reduce the situation that the heat generated by the signal transmission assembly 125 is directly transmitted to the detection assembly 124, which affects the performance of the detection assembly 124.

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

[0055] In some embodiments, the detection assembly 124 comprises a water tank 122 and a reflection assembly 123, the water tank 122 is installed in the mounting base 111, and the reflection assembly 123 is installed in the water tank 122, and the reflection assembly 123 has a detection surface 121.

[0056] In this way, the transducer echo line sequence test device 100 can reflect the ultrasonic waves emitted by the multiple array elements of the ultrasonic transducer 13 through the reflection assembly 123, the ultrasonic transducer 13 can convert the reflected ultrasonic waves into electrical signals and transmit them to the signal transmission assembly 125, and the signal transmission assembly 125 can collect the ultrasonic wave information emitted by the multiple array elements of the ultrasonic transducer 13 and perform data analysis to detect 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, and the water in the water tank 122 is a uniform and controllable medium, which can provide consistent sound speed and propagation characteristics. In a uniform 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 detection of the ultrasonic transducer 13.

[0057] The water tank 122 is a transparent box to facilitate observation of the devices inside the water tank 122, and the reflection assembly 123 can be adhered to the water tank 122 by waterproof glue, which can be set according to actual conditions.

[0058] Referring to Figure 2 and Figure 7In some embodiments, the reflection assembly 123 comprises a first reflection body 1231 and a second reflection body 1232 connected with each other, the first reflection body 1231 and the second reflection body 1232 have a detection surface 121 respectively, the first reflection body 1231 is arranged at a first angle with the horizontal plane, so that when the transducer echo line sequence test device 100 is in the echo detection state, the detection surface 121 is arranged at the first angle with the horizontal plane; the second reflection body 1232 is arranged at a second angle with the horizontal plane, so that when the transducer echo line sequence test device 100 is in the line sequence detection state, the detection surface 121 is arranged at the second angle with the horizontal plane.

[0059] In this way, the reflection assembly 123 can be integrated with the first reflection body 1231 and the second reflection 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 reflection body, and can also perform line sequence detection on the ultrasonic transducer 13 through the reflection surface of the second reflection body, which helps to enrich the functions of the transducer echo line sequence test device 100 and better meet the detection needs of the ultrasonic transducer 13.

[0060] In addition, the reflection assembly 123 has a simple structure, which is convenient for manufacturing the reflection assembly 123 and saves manufacturing costs.

[0061] For example, when the ultrasonic transducer 13 needs to be subjected to echo detection, the ultrasonic transducer 13 can be moved to a position close to the first reflection body 1231, at which time the ultrasonic transducer 13 is opposite to the detection surface 121 of the first reflection body 1231, facilitating the echo detection of the ultrasonic transducer 13.

[0062] For another example, when the ultrasonic transducer 13 needs to be subjected to line sequence detection, the ultrasonic transducer 13 can be moved to a position close to the second reflection body 1232, at which time the ultrasonic transducer 13 is opposite to the detection surface 121 of the second reflection body 1232, facilitating the line sequence detection of the ultrasonic transducer 13.

[0063] For example, the first reflection body 1231 can be arranged at 90° with the horizontal plane, for example, the first reflection body 1231 is arranged at 90° with the horizontal plane; the second reflection body 1232 can be arranged at 30°-90° (not included) with the horizontal plane, for example, the second reflection body 1232 is arranged at 30°, 35°, 45°, 50°, 55°, 60°, 70°, 80°, 89° or other angles with the horizontal plane, which can be set according to actual conditions.

[0064] In some embodiments, the detection assembly 124 further comprises a first mode sensor 1241, a second mode sensor 1242 and a position sensor 1243, all of which are mounted on the water tank 122 and electrically connected to the signal transmission assembly 125, the first mode sensor 1241 is arranged close to the first reflective body 1231 relative to the second mode sensor 1242, the second mode sensor 1242 is arranged close to the first reflective body 1231 relative to the first mode sensor 1241, and the position sensor 1243 is arranged close to the ultrasonic transducer 13 relative to the first mode sensor 1241 and the second mode sensor 1242.

[0065] In this way, the position sensor 1243 can detect the position of the ultrasonic transducer 13, and 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, so as to facilitate the signal transmission assembly 125 to determine which working mode the transducer echo line sequence test device 100 belongs to according to the position of the ultrasonic transducer 13, and to enable the corresponding test process, thereby improving the accuracy of detection of the transducer echo line sequence test device 100.

[0066] In addition, when the transducer echo line sequence test 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 wave of the ultrasonic transducer 13 can be reflected at a predetermined angle, thereby improving the accuracy of detection.

[0067] In some embodiments, the first mode sensor 1241, the second mode sensor 1242 and the position sensor 1243 can be waterproof infrared sensors, waterproof ultrasonic sensors or the like, which can be set according to actual conditions.

[0068] Referring to Figures 8 to 10 In some embodiments, the reflection assembly 123 comprises a reflective body 1233 and an adjusting member 1234 connected to each other, the reflective body 1233 has the detection surface 121, and the adjusting member 1234 is adapted to adjust the angle of the reflective body 1233 relative to the horizontal plane, so that when the transducer echo line sequence test device 100 is in the echo detection state, the detection surface 121 is arranged at a first angle relative to the horizontal plane, as shown in Figure 8 When the transducer echo line sequence test device 100 is in the line sequence detection state, the detection surface 121 is arranged at a second angle relative to the horizontal plane, as shown in Figure 9

[0069] ​Therefore, the angle between the reflecting member 1233 and the horizontal plane can be adjusted by the adjusting member 1234, which helps to improve the flexibility of the adjustment of the reflecting member 1233, and makes the detection surface 121 be arranged at different angles with the horizontal plane, which is convenient for the different detection states of the transducer echo line sequence test device 100, and the detection assembly 124 does not need to separately arrange 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 assembly 124, is convenient for manufacturing, and saves the manufacturing cost.

[0070] In addition, by adjusting the angle between the reflecting member 1233 and the horizontal plane through the adjusting member 1234, it helps to reduce the movement of the transducer adjustment module 112 in the first direction X, and helps to reduce the frequent adjustment caused by the movement of the transducer adjustment module 112, so that the operation is more efficient.

[0071] For example, as shown in Figure 8 When the ultrasonic transducer 13 needs to be detected, the angle between the reflecting member 1233 and the horizontal plane can be adjusted, so that the detection surface 121 is arranged at the first angle with the horizontal plane, and at this time the ultrasonic transducer 13 is opposite to the detection surface 121, which is convenient for the echo detection of the ultrasonic transducer 13.

[0072] For example, as shown in Figure 9 When the ultrasonic transducer 13 needs to be detected, the angle between the reflecting member 1233 and the horizontal plane can be adjusted, so that the detection surface 121 is arranged at the first angle with the horizontal plane, and at this time the ultrasonic transducer 13 is opposite to the detection surface 121, which is convenient for the echo detection of the ultrasonic transducer 13.

[0073] For example, as shown in Figure 9 When the ultrasonic transducer 13 needs to be detected, the angle between the reflecting member 1233 and the horizontal plane can be adjusted, so that the detection surface 121 is arranged at the first angle with the horizontal plane, and at this time the ultrasonic transducer 13 is opposite to the detection surface 121, which is convenient for the echo detection of the ultrasonic transducer 13.

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

[0075] In this way, the linkage body 1237 can be operated by the operating body 1236 to move relative to the mounting shell 1235, thereby driving the reflecting member 1233 to rotate relative to the mounting shell 1235, realizing the linkage of the reflecting member 1233 with the operating body 1236 and the linkage body 1237, and facilitating the angle adjustment of the reflecting member 1233. The linkage of the operating body 1236, the linkage body 1237 and the reflecting member 1233 is simple in implementation and facilitates the manufacturing of the reflecting assembly 123.

[0076] In some embodiments, the operating body 1236 can comprise a knob and a screw connected to each other, the screw is driven to move relative to the mounting shell 1235 by rotating the knob, the linkage body 1237 can comprise a sliding block and a support link connected to each other, the sliding block is sleeved on the outer periphery of the screw, one end of the support link is connected to the sliding block, and the other end of the support link is connected to the reflecting member 1233, the movement of the screw relative to the mounting shell 1235 synchronously drives the sliding block to move relative to the mounting shell 1235, and then drives the reflecting member 1233 to rotate relative to the mounting shell 1235 through the support link.

[0077] In this way, the adjusting member 1234 can form a sliding block rocker mechanism, and the screw and the sliding block are threadedly connected, so that the sliding block rocker mechanism has a self-locking function, thereby facilitating the adjustment of the angle between the detection surface of the reflecting member 1233 and the horizontal plane.

[0078] Since the screw of the operating body 1236 needs to extend out of the water tank 122, an opening needs to be provided on the water tank 122 to meet the extension of the screw, and a sealing waterproof ring can be provided on the opening to improve the sealing between the operating body 1236 and the water tank 122, and the sealing waterproof ring is a circular ring which can be interference-fitted with the screw.

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

[0080] In this way, the angle sensor 1244 can detect the angle between the detection surface 121 and the horizontal plane, and the signal transmission assembly 125 receives the angle signal of 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 test device 100 provided by the embodiment of the present application has an echo detection state and a line sequence detection state, the transducer detection module 12 of the transducer echo line sequence test device 100 is installed on the device main body 11, and the transducer detection module 12 has a detection surface 121; the ultrasonic transducer 13 is installed on the device main body 11. When the transducer echo line sequence test device 100 is in the echo detection state, the detection surface 121 is arranged at a first angle with 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 test device 100 is in the line sequence detection state, the detection surface 121 is arranged at a second angle with 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. In this way, the transducer echo line sequence test device 100 can perform echo detection on the ultrasonic transducer 13 through the detection surface 121 at the first angle, and the transducer echo line sequence test device 100 can also perform line sequence detection on the ultrasonic transducer 13 through the detection surface 121 at the second angle, so that the transducer echo line sequence test device 100 can integrate the echo performance detection function and the multi-element line sequence detection function, which helps to reduce the time and cost of ultrasonic transducer 13 detection, and also helps to enrich the functions of the transducer echo line sequence test device 100, and better meet the detection needs of the ultrasonic transducer 13.

[0082] Please refer to Figure 11 , Figure 11 is a flowchart of a transducer echo line sequence test method provided by the embodiment of the present application, which can be applied to the transducer echo line sequence test device described above. As shown in FIG. N, the method can include steps 210 to 220.

[0083] In step 210, when the transducer echo line sequence test device is in the echo detection state, the detection surface is arranged at a first angle with the horizontal plane, and the waveform data of the feedback signal reflected by the detection surface according to the ultrasonic signal emitted by the plurality of test elements is compared with the preset qualified data to determine the performance result of the transducer.

[0084] In some embodiments, the performance of the transducer can be detected when the transducer echo line sequence test device is in the echo detection state.

[0085] In some embodiments, the transducer detection module further comprises a first mode sensor and a position sensor, and the transducer echo line sequence test method further comprises: determining that the transducer echo line sequence test device is in the echo detection state when the first mode sensor detects that the transducer echo line sequence test device is in an echo detection mode, and the position sensor detects that the detection surface is at a first angle with the horizontal plane.

[0086] In some embodiments, the first mode sensor can be a mode sensor.

[0087] In some embodiments, 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 can be understood that the present application is not limited to the first angle being 90°.

[0089] In some embodiments, the first waveform data corresponding to each of the plurality of test elements is first waveform data corresponding to the first waveform obtained by converting the reflected ultrasonic waves into electrical signals by the transducer after the ultrasonic waves are reflected from the detection surface after the plurality of test elements simultaneously emit ultrasonic waves.

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

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

[0092] In some embodiments, the preset qualified data can be data set in advance. The preset qualified data can reflect whether the performance of the transducer is qualified. For example, when the waveform data is equal to the preset qualified data, it is determined that the performance of the transducer is qualified. For another example, when the waveform data is not equal to the preset qualified data, it is determined that the performance of the transducer is not qualified.

[0093] After the plurality of test elements emit ultrasonic signals, the ultrasonic signals are emitted through the detection surface at 90° with the horizontal plane, and the first waveform data corresponding to the feedback signals obtained from the ultrasonic signals after the emission is compared with the preset qualified data, so as to determine the performance result of the transducer. Specifically, in some embodiments, please refer to Figure 12 , Figure 12 is a structural schematic diagram of a transducer detection module provided by an embodiment of the present application, as Figure 12 shown, the transducer detection module 300 comprises an upper computer 310, a pulse receiver 320, a gating module 330, and an oscilloscope 340, and the transducer echo line sequence test method further comprises the following steps: (1) In a case where the host computer 310 determines that the current state is the echo detection state, the pulse receiver 320 is driven to transmit a pulse signal to the gating module 330; (2) The gating module 330 switches among the channels corresponding to the plurality of test elements in turn according to the pulse signal, and transmits an excitation signal to the test element corresponding to the switched channel through the switched channel, so that the plurality of test elements simultaneously transmit ultrasonic signals. The ultrasonic signals are fed back after being transmitted by the detection surface; (3) The gating module 330 switches among the channels corresponding to the plurality of test elements in turn to receive the feedback signals transmitted by the plurality of test elements respectively, and transmits the feedback signals corresponding to the plurality of test elements respectively to the pulse receiver 320; (4) The oscilloscope 340 collects a plurality of first waveform data corresponding to the plurality of test elements respectively transmitted by the pulse receiver 320, and transmits the plurality of 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 performance of the transducer is qualified.

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

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

[0096] In some embodiments, the host computer 310 is connected with 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 a control signal to the gating module 330, so that the gating module 330 switches the connection channel between the plurality of test elements under the action of the first control signal. For example, the connection channel of the gating module 330 and the transducer is switched from the channel a corresponding to the test element A to the channel b corresponding to the test element B under the action of the first control signal.

[0097] Through the connection between the host computer 310 and the pulse receiver 320, the host computer 310 can transmit a second control signal to the pulse receiver 320, so that the pulse receiver 320 triggers 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 test device is in the echo detection state or the line sequence detection state, a second control signal is transmitted to the pulse receiver 320, so that the pulse receiver 320 triggers the pulse receiver 320 to transmit a pulse signal to the gating module 330 under the action of the second control signal.

[0098] The host computer 310 is connected with the oscilloscope 340, and the host computer 310 can receive waveforms of the multiple test elements collected from the oscilloscope 340, so as to determine waveform data according to the waveforms of the multiple test elements, and further determine the performance of the transducer according to the waveform data.

[0099] In some embodiments, the pulse receiver 320 is connected with the gating module 330 and the oscilloscope 340 respectively. The pulse receiver 320 can be used to transmit a pulse signal to the gating module 330 under the action of the second control signal, so as to prompt the gating module 330 to receive signals corresponding to the waveforms of the multiple test elements, and transmit the signals to the pulse receiver 320, and then the pulse receiver 320 transmits the signals to the oscilloscope 340, so as to collect the waveforms of the multiple test elements through the oscilloscope 340.

[0100] That is, the signal transmission path is: the host computer 310-pulse receiver 320-gating module 330-multiple test elements-gating module 330-pulse receiver 320-oscilloscope 340-host computer 310. Through the signal transmission path, multiple feedback signals corresponding to the multiple test elements respectively are collected. After the host computer 310 collects the multiple feedback signals, that is, after collecting the information of all the test elements, the waveform data is extracted from the multiple feedback signals.

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

[0102] The waveform data extracted from the multiple feedback signals is time domain waveform data, the host computer 310 transforms the time domain waveform data into frequency domain waveform data, so as to calculate the center frequency value, the bandwidth value and the peak-to-peak value according to the frequency domain waveform data, and the host computer 310 compares the center frequency value, the bandwidth value and the peak-to-peak value with the preset qualified data, so as to determine the performance of the transducer.

[0103] In step 220, when the transducer echo line sequence test device is in a line sequence detection state, the detection surface is arranged at a second angle with the horizontal plane, the actual time difference between each adjacent test element in the multiple test elements is determined according to the waveform data of the feedback signal reflected by the ultrasonic signal emitted by the multiple test elements, and whether each test element is correctly welded is determined according to the comparison relationship between the difference between the actual time difference and the theoretical time difference and the preset threshold value.

[0104] In some embodiments, the transducer echo line sequence test device is in a line sequence detection state, which is used to detect whether each test element is arranged in a line sequence, so as to determine whether each test element is welded incorrectly, or to determine the test element welded incorrectly in the plurality of test elements. Therefore, it is not necessary to detect whether each test element is welded correctly by using a voltmeter or the like, so as to improve the efficiency of determining whether the plurality of test elements are welded correctly.

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

[0106] In some embodiments, the waveform data corresponding to the plurality of test elements respectively is waveform data corresponding to the waveforms of the reflected ultrasonic waves converted into electrical signals by the transducer after the ultrasonic waves emitted by the plurality of test elements are reflected by the detection surface in a mirror mode.

[0107] In some embodiments, the preset threshold value can be set in advance. In some embodiments, the preset threshold value can be determined according to the theoretical flight time difference and the actual flight time difference.

[0108] The ultrasonic signals emitted by the plurality of test elements are reflected by the detection surface at the second angle with the horizontal plane to obtain feedback signals corresponding to the ultrasonic signals, and the actual flight time difference between each adjacent test element in the plurality of test elements is determined according to the second waveform data of the feedback signals. Further, the difference between the actual flight time difference and the theoretical flight time difference is compared with the preset threshold value, so as to determine whether each adjacent test element is welded correctly. Specifically: In some embodiments, please refer to Figure 13 , Figure 13 is another structure diagram of a transducer detection module provided by the embodiments of the present application, as shown in Figure 13 the transducer detection module includes a host computer 310, a pulse receiver 320, a gating module 330, and an oscilloscope 340. The transducer echo line sequence test method can further include the following steps: (1) When the host computer 310 determines that the current state is a line sequence detection state, the host computer 310 drives the pulse receiver 320 to emit a pulse signal to the gating module 330; (2) The gating module 330 switches in the channels corresponding to the plurality of test elements according to the pulse signal, and emits an excitation signal to the test element corresponding to the switched channel through the switched channel, so that the plurality of test elements emit ultrasonic signals, and the ultrasonic signals emit feedback signals through the detection surface; (3) The gating module 330 switches in the channels corresponding to the multiple test elements in turn to receive the feedback signals transmitted by the multiple test elements respectively, and transmits the feedback signals corresponding to the multiple test elements respectively to the pulse receiver 320; (4) The oscilloscope 340 collects the multiple second waveforms corresponding to the multiple test elements transmitted by the pulse receiver 320, and transmits the multiple second waveforms to the host computer 310; (5) The host computer 310 determines the actual time-of-flight difference value of each test element in the multiple test elements according to the first effective echo position of the second waveform data of the multiple second waveforms.

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

[0110] After the host computer 310 collects the multiple feedback signals, i.e., after collecting the information of all the test elements, the actual time-of-flight difference value between each adjacent test element in the multiple test elements is determined according to the first effective echo position corresponding to each adjacent test element in the multiple second waveform data corresponding to the multiple feedback signals.

[0111] After the host computer 310 determines the actual time-of-flight difference value between each adjacent test element in the multiple test elements, the actual time-of-flight difference value between each adjacent test element in the multiple test elements is compared with the preset threshold value according to the difference between the actual time-of-flight difference value and the theoretical time-of-flight difference value between each adjacent test element in the multiple test elements, to determine the actual time-of-flight difference value between each adjacent test element in the multiple test elements.

[0112] Exemplarily, the multiple test elements include a test element A and a test element B arranged adjacent to the test element A. The host computer 310 determines the peak time (i.e., the TOP value) corresponding to the test element A according to the first effective echo position of the second waveform data corresponding to the test element A; the host computer 310 determines the peak time corresponding to the test element B according to the first effective echo position of the second waveform data corresponding to the test element B; and the host computer 310 determines the actual time-of-flight difference value between the test element A and the test element B according to the difference between the peak time corresponding to the test element A and the peak time corresponding to the test element B. In this way, the actual time-of-flight difference value between each test element in the multiple test elements can be obtained.

[0113] Exemplarily, the plurality of test elements include a test element A and a test element B adjacent to test element A. The host computer 310 compares the actual time-of-flight difference between test element A and test element B with the theoretical time-of-flight difference between test element A and test element B to determine whether test element A complies with the linear arrangement, thereby determining whether test element A has a welding error.

[0114] The theoretical flight time difference may be pre-set, and the corresponding theoretical flight time difference between each test element in the plurality of test elements may be determined by referring to the following method. Specifically, the transducer echo line sequence test method may further include the following steps: (1) Determine the acoustic path difference between each adjacent test array element in the plurality of test array elements according to the spacing between adjacent test array elements in the plurality of test array elements and the second angle.

[0115] (2) Based on the acoustic path difference and the speed of sound, determine the theoretical flight time difference between each adjacent test array element.

[0116] The host computer determines the theoretical flight time difference between each adjacent test array element according to the sound path difference and the sound speed between each adjacent test array element in the plurality of test array elements.

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

[0118] in," " is the theoretical flight time difference between adjacent test array elements;" " is the spacing between adjacent test elements;" ” is the second angle.

[0119] After obtaining the acoustic path differences between adjacent test elements in the above manner, the theoretical flight time differences between adjacent test elements are determined based on the acoustic path differences and the speed of sound. This can be determined using the following expression: in," " is the theoretical flight time difference between adjacent test array elements;" ” is the speed of sound.

[0120] The theoretical flight time difference between each adjacent test element is obtained by the above method, and the difference between the theoretical flight time difference between each adjacent test element and its corresponding actual flight time difference is compared with a preset threshold to determine whether the test element welding is correct. Specifically: In some embodiments, the transducer echo line sequence testing method can comprise the step of: if the difference between the corresponding theoretical time of flight difference value and the actual time of flight difference value of the target test element pair is less than or equal to the preset threshold value, determining that the test elements included in the target test element are correctly welded.

[0121] In some embodiments, the target test element is any adjacent test element in the plurality of 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 value between test element A and test element B is "tA-B", the actual time of flight difference value between test element A and test element B is "tA-B", the preset threshold value is "tA-B", and if "tA-B ", test element A and test element B are correctly welded.

[0123] In some embodiments, the preset threshold value is related to the difference between the theoretical time of flight difference value and the actual time of flight difference value of each adjacent test element in the plurality of test elements. That is, the host computer can set a relatively appropriate value as the preset value according to the theoretical time of flight difference value and the actual time of flight difference value, to allow the influence of unavoidable interference. For example, placement error, medium disturbance, oscilloscope sampling error, reflection deformation, etc.

[0124] In a specific embodiment, the preset threshold value can be the difference between the theoretical time of flight difference value and the actual time of flight difference value, i.e. .

[0125] By setting the preset threshold value as the boundary condition for judging linearity, it is determined whether each test element in the plurality of test elements is correctly welded in the above manner. Thus, it is not necessary to detect each test element one by one, so as to improve the detection efficiency.

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

[0127] In some embodiments, the transducer echo line sequence testing method can comprise the step of: if the difference between the corresponding theoretical time of flight difference value and the actual time of flight difference value of the target test element pair is greater than the preset threshold value, determining that the test elements included in the target test element are incorrectly welded.

[0128] ​​​The application determines whether a certain test element is welded correctly by comparing the difference between the actual time-of-flight difference between the test element and its adjacent test element and the theoretical time-of-flight difference with a preset threshold, thereby determining whether the test element is welded correctly. Thus, without the need for individual testing of each test element by a voltmeter or the like, efficient testing is achieved by the transducer echo line sequence testing device.

The second execution module 420 is configured to, when the transducer echo line sequence testing device is in the line sequence detection state, set the detection surface at a second angle with the horizontal plane, determine the actual time-of-flight difference between each adjacent test element in the plurality of test elements according to the waveform data of the feedback signal obtained by reflecting the ultrasonic signal emitted by the plurality of test elements on the detection surface, and determine whether each test element is welded correctly according to the comparison relationship between the difference between the actual time-of-flight difference and the theoretical time-of-flight difference and the preset threshold.
