[0002] As the quality of life improves, users are increasingly demanding higher performance from home appliances. The acoustic performance of home appliances must comply with relevant standards. Therefore, testing the acoustic performance of equipment is essential.

[0003] To capture the sound source distribution of the equipment, some technologies use floor-standing manual stands, six of which are required. Others use semi-automatic adjustment systems, which are placed on the top of the anechoic chamber and raised and lowered by a winch.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] Adjusting the microphone positions is only semi-automatic. Some directional movements still require manual adjustments and the coordination of multiple people, making the relative positions of the microphones prone to deviation.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0062] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0063] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0064] Combine Figures 1 to 4 As shown ( Figures 1 to 4 The top of the drawing is on the left side of the drawing). The embodiment of the present disclosure provides a device for controlling the position of a point. The device includes: a support frame 1, an X-axis drive device 2, a Y-axis drive device 3, and a Z-axis drive device 4. The support frame 1 is set at a preset height in a hanging manner. Figure 2 and Figure 3 The X-axis drive device 2 is mounted on the support frame 1. The X-axis drive device 2 includes an X-axis power output unit connected to an X-axis mounting portion 27. The X-axis mounting portion 27 is used to mount a microphone, which is defined as the X-axis microphone. The X-axis power output unit outputs power from the X-axis drive device 2 to drive the X-axis mounting portion 27 to move along the X-axis, thereby driving the X-axis microphone to move along the X-axis.

[0065] See also Figure 2 and Figure 4 The Y-axis driving device 3 is slidably arranged on the supporting frame 1 and can be driven to move along the X-axis. The Y-axis driving device 3 and the X-axis power output unit can move along the X-axis under the drive of the X-axis power output unit. The Y-axis driving device 3 includes a Y-axis power output unit, and the Y-axis power output unit is connected to the Y-axis mounting unit 36. The Y-axis mounting unit 36 ​​is also used to install a microphone, which is defined as a Y-axis microphone. The Y-axis power output unit outputs the power of the Y-axis driving device 3 to drive the Y-axis mounting unit 36 ​​to move along the Y-axis, and then drives the Y-axis microphone to move along the Y-axis. Since the Y-axis driving device 3 can move along the X-axis due to being driven by the X-axis power output unit, the Y-axis microphone will move along the X-axis together with the Y-axis driving device 3. In this way, the Y-axis microphone can move along both the X-axis and the Y-axis.

[0066] Combine Figure 2 and Figure 4As shown, the Z-axis drive device 4 is connected to the X-axis power output unit to move along the X-axis under the drive of the X-axis power output unit. Alternatively, the Z-axis drive device 4 is connected to the Y-axis power output unit to move along the X-axis under the drive of the Y-axis power output unit. Alternatively, the Z-axis drive device 4 is connected to both the X-axis power output unit and the Y-axis power output unit to move along the X-axis and Y-axis respectively under the drive of the X-axis power output unit and the Y-axis power output unit. The Z-axis drive device 4 includes: a Z-axis power output unit, and the Z-axis power output unit is connected to the Z-axis mounting portion 44. The Z-axis mounting portion 44 is also used to mount a microphone, which is defined as a Z-axis microphone. The Z-axis power output unit outputs the power of the Z-axis drive device 4 to drive the Z-axis mounting portion 44 to move along the Z-axis, thereby driving the Z-axis microphone to move along the Z-axis. In this way, the Z-axis microphone can be driven to move along the X-axis, Y-axis, and / or Z-axis.

[0067] Using the device for controlling the position of points provided by the embodiment of the present disclosure, the X-axis power output portion of the X-axis drive device 2 is connected to the X-axis mounting portion 27, thereby being able to drive the corresponding microphone to move along the X-axis. The Y-axis drive device 3 is connected to the X-axis power output portion, and the Y-axis power output portion is connected to the Y-axis mounting portion 36, thereby being able to drive the corresponding sensor to move along the X-axis and Y-axis. The Z-axis drive device 4 is connected to the X-axis power output portion and / or the Y-axis power output portion, thereby being able to be driven to move along the X-axis and / or the Y-axis. At the same time, the Z-axis power output portion is connected to the Z-axis mounting portion 44, thereby being able to drive the corresponding sensor to move along the X-axis, the Y-axis and / or the Z-axis. In this way, the microphone coordinates can be arranged quickly, safely, efficiently, accurately and fully automatically through multi-axis linkage. No manual operation is required, which improves the accuracy of the microphone position and saves manpower.

[0068] Alternatively, see Figure 2 、 3 As shown in Figures 5 and 6, the X-axis drive device 2 includes: an X-axis drive mechanism 21 and an X-axis transmission mechanism. The X-axis drive mechanism 21 is arranged on the support frame 1 to be fixed. The X-axis drive mechanism 21 includes a first drive output end, which is connected to the X-axis transmission mechanism in a transmission manner, thereby transmitting power to the X-axis transmission mechanism to drive it to transmit along the X-axis. The X-axis mounting portion 27 is provided on the X-axis transmission mechanism. Here, the X-axis transmission mechanism serves as an X-axis power output portion for outputting the driving force.

[0069] Alternatively, see Figures 1 to 4 The support frame 1 has a first side 11 and a second side 12. The first side 11 and the second side 12 are two opposite sides on the X axis. Optionally, the first side 11 is the front side of the support frame 1, and the second side 12 is the rear side of the support frame 1 (relative to the Figure 1 for example).

[0070] Alternatively, see Figure 5 The X-axis drive mechanism 21 includes an X-axis drive motor 211, which is fixed to the first side 11 of the support frame 1 via an X-axis motor bracket 212. The power output shaft of the X-axis drive motor 211 is in transmission connection with the X-axis transmission mechanism. Here, the power output shaft of the X-axis drive motor 211 serves as a first drive output end.

[0071] Alternatively, see Figure 5 and Figure 6 The X-axis transmission mechanism includes a first transmission assembly 22 and a second transmission assembly 23. The first transmission assembly 22 is in transmission connection with the first drive output end, that is, in transmission connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. Furthermore, the first transmission assembly 22 is also connected to the Y-axis drive device 3 to drive the Y-axis drive device 3 to move along the X-axis. The second transmission assembly 23 is also in transmission connection with the first drive output end, that is, in transmission connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. Furthermore, the second transmission assembly 23 is also connected to the X-axis mounting portion 27 to drive the X-axis mounting portion 27 to move along the X-axis. The transmission speed of the first transmission assembly 22 is greater than the transmission speed of the second transmission assembly 23. Thus, the movement speed of the Y-axis drive device 3 along the X-axis is greater than the movement speed of the X-axis mounting portion 27 along the X-axis. In this way, positional interference between the Y-axis driving device 3 and the X-axis mounting portion 27 can be avoided, and the X-axis mounting portion 27 and the Y-axis driving device can be driven to their respective positions by synchronously driving the X-axis driving device on the X-axis mounting portion 27 and the Y-axis driving device.

[0072] Optionally, the first transmission assembly 22 and the second transmission assembly 23 are arranged along the Z axis (up and down).

[0073] Optionally, the first transmission assembly 22 includes: a first gear assembly 221, a second gear assembly 222 and a first conveyor belt 223. Figure 5 The first gear assembly 221 is provided on the first side 11 of the support frame 1 and is in driving connection with the first drive output end, that is, in driving connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. Figure 6 The second gear assembly 222 is disposed on the second side 12 of the support frame 1 and can be driven to rotate by power. The first conveyor belt 223 is sleeved on the first gear assembly 221 and the second gear assembly 222. When the first gear assembly 221 rotates, it can transmit power to the first conveyor belt 223. The first conveyor belt 223 then transmits power to the second gear assembly 222, thereby causing the second gear assembly 222 to rotate. Here, the first conveyor belt 223 serves as one of the X-axis power output parts. The Y-axis drive device 3 is on the first conveyor belt 223 to follow the first conveyor belt 223 and move along the X-axis.

[0074] Optionally, continue with Figure 5 The first gear assembly 221 includes: a first driving wheel 2211 and a first driven wheel 2212. The first driving wheel 2211 is transmission-connected to the first drive output end, that is, the first driving wheel 2211 is arranged on the power output shaft of the X-axis drive motor 211. In this way, the X-axis drive motor 211 transmits power to the first driving wheel 2211 through the power output shaft, and drives the first driving wheel 2211 to rotate. The first driven wheel 2212 is rotatably arranged on the first side 11 of the support frame 1. Specifically, a first gear bracket 24 is provided on the first side 11 of the support frame 1. A first mounting post 241 is provided on the first gear bracket 24. The first driven wheel 2212 is rotatably mounted on the first mounting post 241 and is arranged parallel to the first driving wheel 2211. The first side of the first conveyor belt 223 is mounted on the first driving wheel 2211 and the first driven wheel 2212. In this way, when the first driving wheel 2211 is driven to rotate, power can be transmitted to the first conveyor belt 223, and the first conveyor belt 223 then drives the first driven wheel 2212 to rotate.

[0075] Optionally, the X-axis motor bracket 212 is connected to the first gear bracket 24 to make the X-axis drive motor 211 more stable.

[0076] Optionally, continue with Figure 6 The second gear assembly 222 includes a second driven wheel 2221 and a third driven wheel 2222. Both the second driven wheel 2221 and the third driven wheel 2222 are rotatably mounted on the second side 12 of the support frame 1. Specifically, a second gear bracket 25 is provided on the second side 12 of the support frame 1. The second gear bracket 25 is provided with a second mounting post 251 and a third mounting post 252. The second driven wheel 2221 is rotatably mounted on the second mounting post 251, and the third driven wheel 2222 is rotatably mounted on the third mounting post 252. Simultaneously, the second driven wheel 2221 and the third driven wheel 2222 are arranged side by side. The second side of the first conveyor belt 223 is mounted on the second driven wheel 2221 and the third driven wheel 2222. Thus, when the first conveyor belt 223 rotates, it can drive the second driven wheel 2221 and the third driven wheel 2222 to rotate.

[0077] Optionally, the second transmission assembly 23 includes: a third gear assembly 231, a fourth gear assembly 232 and a second conveyor belt 233. Figure 5 The third gear assembly 231 is disposed on the first side 11 of the support frame 1 and is in transmission connection with the first drive output end, that is, in transmission connection with the power output shaft of the X-axis drive motor 211, so as to be driven by the X-axis drive device 2. That is, the third gear assembly 231 and the first gear assembly 221 are driven by the same power source. Figure 6The fourth gear assembly 232 is disposed on the second side 12 of the support frame 1 and can be driven to rotate by power. The second conveyor belt 233 is sleeved on the third gear assembly 231 and the fourth gear assembly 232. When the third gear assembly 231 rotates, it can transmit power to the second conveyor belt 233. The second conveyor belt 233 then transmits power to the fourth gear assembly 232, thereby rotating the fourth gear assembly 232. Here, the second conveyor belt 233 serves as the second X-axis power output unit. The X-axis mounting portion 27 is placed on the second conveyor belt 233 so that it can move along the X-axis along with the second conveyor belt 233 together with the X-axis microphone.

[0078] Optionally, see again Figure 5 The third gear assembly 231 includes a second driving wheel 2311 and a fourth driven wheel 2312. The second driving wheel 2311 is drivingly connected to the first drive output end, that is, the second driving wheel 2311 is mounted on the power output shaft of the X-axis drive motor 211. Thus, the X-axis drive motor 211 transmits power to the second driving wheel 2311 via the power output shaft, driving the second driving wheel 2311 to rotate. In other words, the power output shaft of the X-axis drive motor 211 simultaneously drives the first driving wheel 2211 and the second driving wheel 2311. The fourth driven wheel 2312 is rotatably mounted on the first side 11 of the support frame 1. Specifically, the fourth driven wheel 2312 is rotatably mounted on the first mounting post 241 and is arranged parallel to the second driving wheel 2311. The first side of the second conveyor belt 233 is mounted on the second driving wheel 2311 and the fourth driven wheel 2312. In this way, when the second driving wheel 2311 is driven to rotate, power can be transmitted to the second conveyor belt 233, and the second conveyor belt 233 then drives the fourth driven wheel 2312 to rotate.

[0079] Optionally, see again Figure 6 The fourth gear assembly 232 includes: a fifth driven wheel 2321 and a sixth driven wheel 2322. The fifth driven wheel 2321 and the sixth driven wheel 2322 are both rotatably disposed on the second side 12 of the support frame 1. Specifically, the fifth driven wheel 2321 is rotatably mounted on the second mounting post 251, and the sixth driven wheel 2322 is rotatably mounted on the third mounting post 252. At the same time, the fifth driven wheel 2321 and the sixth driven wheel 2322 are arranged in parallel. The second side of the second conveyor belt 233 is mounted on the fifth driven wheel 2321 and the sixth driven wheel 2322. In this way, when the second conveyor belt 233 rotates, it can drive the fifth driven wheel 2321 and the sixth driven wheel 2322 to rotate.

[0080] As can be seen from the above, the structures of the first transmission assembly 22 and the second transmission assembly 23 are similar. Both are driven by the X-axis drive motor 211. The diameter of the first driving wheel 2211 is larger than the diameter of the second driving wheel 2311. In this way, the transmission speed of the first transmission assembly 22 can be greater than the transmission speed of the second transmission assembly 23.

[0081] Optionally, the X-axis transmission mechanism further includes: a first beam 26. The length direction of the first beam 26 is arranged along the Y-axis, and the first beam 26 is slidably arranged on the support frame 1. Specifically, see Figure 4 、 7 9, a first slider 261 and a second slider 262 are respectively provided on one side of the first crossbeam 26 and near its two ends, and a first slide rail 13 and a second slide rail 14 are respectively provided on both sides of the support frame 1.

In this way, the first crossbeam 26 can slide on the support frame 1. See again Figure 2 The X-axis mounting portion 27 is connected to the first beam 26. In this way, when the second conveyor belt 233 drives the X-axis mounting portion 27 to move along the X-axis, the X-axis mounting portion 27 can drive the first beam 26 to move along the X-axis. Here, the first beam 26 serves as the third X-axis power output portion.

Thus, when the first crossbeam 26 moves along the X-axis, the first Z-axis drive device 401 and / or the second Z-axis drive device 402 also move along the X-axis. In this manner, the Z-axis microphone mounted on the Z-axis drive device 4 can be driven by the Z-axis drive device 4 to move along the Z-axis, and can also move along the X-axis along with the Z-axis drive device.

The Y-axis drive mechanism 32 includes a second drive output end. The Y-axis transmission mechanism is provided with the second crossbeam 31 and is in transmission connection with the second drive output end. In this way, the Y-axis transmission mechanism can move along the Y-axis under the action of the power output by the Y-axis drive mechanism 32.

Thus, when the second crossbeam 31 moves along the X-axis, the third Z-axis drive device 403 can also move along the X-axis. This allows the Z-axis microphone, which is mounted on the third Z-axis drive device 403, to be driven by the third Z-axis drive device 403 and to move along both the Z-axis and the X-axis.

Here, the third conveyor belt 34 serves as one of the Y-axis power output components.

[0089] The Y-axis mounting portion 36 is disposed on the third conveyor belt 34. In this way, when the third conveyor belt 34 moves, it can drive the Y-axis microphone installed on the Y-axis mounting portion 36 to move along the Y-axis.

[0090] Optionally, the third conveyor belt 34 is sleeved on the third driving wheel 33 and the driven wheel assembly 35, thereby forming an inner conveying side 341 and an outer conveying side 342.

Specifically, the fifth gear bracket 372 is disposed on the Y-axis motor bracket 322, and the two ends of the sixth mounting column 373 are connected to the top and bottom of the fifth gear bracket 372. The first tensioning pulley 371 is rotatably disposed on the sixth mounting column 373. Optionally, when there are multiple first tensioning pulleys 371, the fifth gear bracket 372 can be directly disposed on the second beam 31 in addition to being disposed on the Y-axis motor bracket 322.

In this way, the tensioning assembly 37, the third driving pulley 33, the seventh driven pulley 351 and the eighth driven pulley 352 cooperate to support and tension the third conveyor belt 34.

[0096] When the first tensioning wheel 371 is mounted on the Y-axis motor bracket 322, a predetermined distance exists between the first tensioning wheel 371 and the third driving wheel 33 on the X-axis. Furthermore, different sides of the third conveyor belt 34 contact the first tensioning wheel 371 and the third driving wheel 33, respectively. Specifically, the third driving wheel 33 contacts the inner conveying side 341 of the third conveyor belt 34, while the first tensioning wheel 371 contacts the outer conveying side 342 of the third conveyor belt 34. The third driving wheel 33, the seventh driven wheel 351, and the eighth driven wheel 352 are staggered relative to each other on the X-axis. The first tensioning wheel 371, the seventh driven wheel 351, and the eighth driven wheel 352 are also staggered relative to each other on the X-axis. This, in conjunction with the first tensioning wheel 371 and the third driving wheel 33, allows the third conveyor belt 34 to be stretched and tensioned in different directions.

[0097] When the first tensioning wheel 371 is directly disposed on the second crossbeam 31, the first tensioning wheel 371 is located between the Y-axis motor bracket 322 and the third gear bracket 353, or between the Y-axis motor bracket 322 and the fourth gear bracket 355.

The third conveyor belt 34 is arranged on the second tensioning wheel 374, the third driving wheel 33 and the third tensioning wheel 375 in a staggered manner along the direction of the Y-axis. Specifically, the third conveyor belt 34 is first mounted on the front side of the second tensioning wheel 374 (the side facing the second side 12 of the support frame 1), then mounted on the rear side of the third driving wheel 33 (the side facing the first side 11 of the support frame 1), and then mounted on the front side of the third tensioning wheel 375 (the side facing the second side 12 of the support frame 1).

[0120] Combine Figure 16As shown, an embodiment of the present disclosure provides a system for controlling a position. The system includes a hoisting device 9 and the aforementioned device for controlling a position. The hoisting device 9 is connected to a lifting frame 161 of a support frame 1 via a lifting rope 162 to adjust the height of the lifting frame 161.

[0121] When performing a sound source distribution test on a device under test 10, the device under test 10 is typically placed in an anechoic chamber. A device for controlling the position of the points is positioned above the device under test 10, and multiple microphones are mounted one-to-one on the X-axis mounting portion 27, the Y-axis mounting portion 36, and the Z-axis mounting portion 44 to pick up the sound generated by the device under test 10.

[0122] Optionally, the hoisting device 9 is fixed to the side wall of the anechoic chamber. Optionally, the hoisting device 9 is a double-drum hoist capable of retracting and extending four lifting ropes 162. Accordingly, the lifting frame 161 is provided with four lifting rings to be connected to the four lifting ropes 162 respectively. Optionally, two lifting rings are provided on the first side 11 of the support frame 1, i.e., the first side 11 of the lifting frame 161. The other two lifting rings are provided on the second side 12 of the support frame 1, i.e., the second side 12 of the lifting frame 161. In this way, the lifting and lowering of the lifting frame 161 can be controlled more smoothly.

[0123] Combine Figure 17 As shown, an embodiment of the present disclosure provides a method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0124] S101: The processor obtains environmental parameters of a test environment.

[0125] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0126] S103: The processor controls the support frame and the driving device to operate so as to drive the microphone to a reset point.

[0127] Sensors are used to obtain environmental parameters of the test environment, namely, the indoor environmental parameters of the anechoic chamber. Optionally, these environmental parameters include one or more of the following: ambient temperature, ambient humidity, and ambient atmospheric pressure. These environmental parameters can affect the accuracy with which the microphone picks up the sound produced by the device under test. Therefore, the microphone's reset point is determined based on these environmental parameters. When the dimensions of the device under test are constant, the distances the processor calculates for the microphone's movement along the X, Y, and / or Z axes are fixed. The reset point serves as the starting point for the microphone's movement. Therefore, environmental parameters affect the microphone's reset point, and thus its target position. The support frame and drive mechanism are controlled to move the microphone to the reset point. Consequently, when the reset point changes, the microphone's target position also changes, meaning the relative position of the microphone to the device under test changes. As can be seen from the structure of the point position control system described above, the support frame comprises a fixed frame and a lifting frame assembly. Therefore, the lifting frame can be controlled along the Z axis by controlling the operation of the hoist mechanism, thereby controlling the height of the lifting frame and, consequently, adjusting the height of the drive mechanism and microphone as a whole. The position of the corresponding microphone on the X-axis, Y-axis and / or Z-axis can be individually adjusted by controlling the operation of the driving device.

[0128] Using the method for controlling the position of points provided by the embodiment of the present disclosure, the environmental parameters of the test environment are first obtained. Based on the structure of the system for controlling the position of points, and in combination with the environmental parameters, the reset point of the microphone is determined. Based on the reset point, the support frame and the drive device are controlled to operate to drive the corresponding microphone to move on the X-axis, Y-axis and / or Z-axis, thereby moving the corresponding microphone to the reset point. In this way, the reset point of the microphone is adaptively adjusted based on the environmental parameters, which can make the target position of the microphone more accurate, and based on the system for controlling the position of points, the microphone coordinates can be arranged quickly, safely, efficiently, accurately, and fully automatically without manual operation. In this way, the accuracy of the microphone position can be improved and manpower can be saved.

[0129] Combine Figure 18 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0130] S101: The processor obtains environmental parameters of a test environment.

[0131] S112: When the environmental parameter is within the corresponding preset parameter range, the processor determines the preset reference point of each microphone as the corresponding reset point.

[0132] S122: When the environmental parameter is outside the corresponding preset parameter range, the processor corrects the preset reference point of each microphone and determines the corrected preset reference point as the corresponding reset point.

[0133] S103: The processor controls the support frame and the driving device to operate so as to drive the microphone to a reset point.

[0134] The memory pre-stores preset parameter ranges, with different preset parameter ranges corresponding to different types of preset parameters. As can be seen from the system described above, there are multiple drive devices, each corresponding to a microphone. Each microphone has its own preset reference point. The preset reference point serves as the preset starting point for the microphone's movement. If the environmental parameters are within the corresponding preset parameter range, this indicates that the variation in the current environmental parameters relative to the environmental parameters corresponding to the preset reference point is within an acceptable range, and the current environmental parameters do not significantly affect the microphone's sound pickup accuracy. The preset reference point of each microphone is then determined as its corresponding reset point. Conversely, if the environmental parameters are outside the corresponding preset parameter range, this indicates that the variation in the current environmental parameters relative to the environmental parameters corresponding to the preset reference point is significant. In this case, the air has a certain influence on the sound propagation parameters, which in turn affects the microphone's sound pickup accuracy. Therefore, the preset reference point of each microphone is corrected, and the corrected preset reference point is determined as its corresponding reset point. In this manner, based on the comparison of the environmental parameters with the preset parameter range, a determination is made as to whether the preset reference point of each microphone should be corrected. In this way, the starting position of each microphone can be made more accurate, thereby making the target position of the microphone, that is, the relative position between the microphone and the device under test, more accurate.

[0135] Optionally, at S122, the processor corrects a preset reference point of each microphone when the environmental parameters include the ambient temperature, including:

[0136] When the ambient temperature is less than or equal to a lower limit of a preset temperature range, the processor performs a positive correction on the coordinates of the preset reference points of each microphone.

[0137] When the ambient temperature is greater than or equal to an upper limit of a preset temperature range, the processor performs a negative correction on the coordinates of the preset reference points of each microphone.

[0138] High temperatures increase the viscosity of air, which in turn slows sound propagation and changes the wavelength and frequency of sound. This can cause the sound picked up by the microphone to slightly increase in volume. Conversely, low temperatures can cause the sound picked up by the microphone to slightly decrease in volume. Therefore, if the ambient temperature is less than or equal to the lower limit of the preset temperature range, indicating that the temperature is too low, the coordinates of each microphone's preset reference point are corrected positively. A positive correction here means moving the coordinates of the preset reference point closer to the device under test, meaning that the microphone's starting point is closer to the device under test. If the ambient temperature is greater than or equal to the upper limit of the preset temperature range, indicating that the temperature is too high, a negative correction is made to the coordinates of the microphone's preset reference point. A negative correction here means moving the coordinates of the preset reference point further away from the device under test, meaning that the microphone's starting point is further away from the device under test. In this way, by correcting the coordinates of each microphone's preset reference point, i.e., adjusting the reset point, the effect of ambient temperature on sound pickup accuracy is compensated for, resulting in more accurate microphone pickup.

[0139] Optionally, the preset temperature range is (20°C, 26°C). When making a positive correction, the correction value is +2mm, and when making a negative correction, the correction value is -2mm. For example, assuming the coordinates of the preset reference point are (0,0,0), when making a positive correction, the coordinates of the preset reference point are corrected to (2,2,2). When making a negative correction, the coordinates of the preset reference point are corrected to (-2,-2,-2).

[0140] Optionally, at S122, when the environmental parameters include ambient humidity, the processor corrects a preset reference point of each microphone, including:

[0141] When the ambient humidity is less than or equal to a lower limit of a preset humidity range, the processor performs a negative correction on the coordinates of the preset reference points of each microphone.

[0142] When the ambient humidity is greater than or equal to an upper limit of a preset humidity range, the processor performs a positive correction on the coordinates of the preset reference points of each microphone.

[0143] In contrast to ambient temperature, low humidity increases the viscosity of the air, which in turn causes the sound picked up by the microphone to slightly increase in volume. Conversely, high humidity causes the sound picked up by the microphone to slightly decrease in volume. Therefore, if the ambient humidity is less than or equal to the lower limit of the preset humidity range, indicating that the humidity is too low, the coordinates of the preset reference point of each microphone are negatively corrected. Here, a negative correction means moving the coordinates of the preset reference point away from the device under test, meaning that the starting point of the microphone is further away from the device under test. If the ambient humidity is greater than or equal to the upper limit of the preset humidity range, indicating that the humidity is too high, the coordinates of the preset reference point of each microphone are positively corrected. Here, a positive correction means moving the coordinates of the preset reference point closer to the device under test, meaning that the starting point of the microphone is closer to the device under test. In this way, by correcting the coordinates of each microphone's preset reference point, i.e., adjusting the reset point, the effect of ambient humidity on sound pickup accuracy is compensated, resulting in more accurate microphone pickup.

[0144] Optionally, the preset humidity range is (30%, 70%). When a positive correction is made, the correction value is +1mm, and when a negative correction is made, the correction value is -1mm. For example, assuming the coordinates of the preset reference point are (0, 0, 0), when a positive correction is made, the coordinates of the preset reference point are corrected to (1, 1, 1). When a negative correction is made, the coordinates of the preset reference point are corrected to (-1, -1, -1).

[0145] Optionally, at S122, the processor corrects a preset reference point of each microphone when the environmental parameters include the ambient atmospheric pressure, including:

[0146] When the ambient atmospheric pressure is less than or equal to a lower limit of a preset atmospheric pressure range, the processor performs a negative correction on the coordinates of the preset reference points of each microphone.

[0147] When the ambient atmospheric pressure is greater than or equal to an upper limit of a preset atmospheric pressure range, the processor performs a positive correction on the coordinates of the preset reference points of each microphone.

[0148] In contrast to ambient temperature, low air pressure increases air viscosity, which in turn causes the sound picked up by the microphone to slightly increase in volume. Conversely, high air pressure causes the sound picked up by the microphone to slightly decrease in volume. Therefore, if the ambient atmospheric pressure is less than or equal to the lower limit of the preset atmospheric pressure range, indicating that the atmospheric pressure is too low, the coordinates of the preset reference point of each microphone are negatively corrected. Here, a negative correction means moving the coordinates of the preset reference point away from the device under test, meaning that the starting point of the microphone is further away from the device under test. If the ambient atmospheric pressure is greater than or equal to the upper limit of the preset atmospheric pressure range, indicating that the atmospheric pressure is too high, the coordinates of the preset reference point of each microphone are positively corrected. Here, a positive correction means moving the coordinates of the preset reference point closer to the device under test, meaning that the starting point of the microphone is closer to the device under test. In this way, by correcting the coordinates of each microphone's preset reference point, i.e., adjusting the reset point, the effect of ambient atmospheric pressure on sound pickup accuracy is compensated, resulting in more accurate microphone pickup.

[0149] Optionally, the preset atmospheric pressure range is (86kPa, 106kPa). When making a positive correction, the correction value is +1mm, and when making a negative correction, the correction value is -1mm. For example, assuming the coordinates of the preset reference point are (0,0,0), when making a positive correction, the coordinates of the preset reference point are corrected to (1,1,1). When making a negative correction, the coordinates of the preset reference point are corrected to (-1,-1,-1).

[0150] Optionally, when the ambient temperature, ambient humidity, and ambient atmospheric pressure all meet the conditions for correcting the preset reference point, the correction values ​​corresponding to each environmental parameter can be superimposed. For example, assume that the coordinates of the preset reference point are (0,0,0). If the current ambient temperature is greater than or equal to 26°C, the coordinates of the preset reference point need to be corrected to (-2,-2,-2). If the current ambient humidity is greater than or equal to 70%, the coordinates of the preset reference point need to be corrected to (1,1,1). If the current ambient atmospheric pressure is greater than or equal to 106kPa, the coordinates of the preset reference point need to be corrected to (1,1,1). The processor then combines the current ambient temperature, ambient humidity, and ambient atmospheric pressure, and ultimately corrects the coordinates of the preset reference point to (0,0,0).

[0151] It is understandable that there are some microphones that cannot move on a certain axis. Specifically, from the structure of the system for controlling the position of points mentioned above, it can be seen that the X-axis microphone can be moved on the X-axis by the X-axis drive device, and can also be moved on the Z-axis by the hoisting device, but cannot be moved on the Y-axis. Therefore, when the coordinates of the preset reference point of the X-axis microphone are corrected, its Y-axis coordinates are not corrected. That is, when the coordinates of the preset reference point of each microphone are corrected, the coordinates of the axis on which the microphone can move are corrected. Alternatively, although its Y-axis coordinates are corrected, when controlling the movement of the X-axis microphone, its Y-axis coordinates cannot be changed.

[0152] Combine Figure 19 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0153] S101: The processor obtains environmental parameters of a test environment.

[0154] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0155] S103: The processor controls the support frame and the driving device to operate so as to drive the microphone to a reset point.

[0156] S104: The processor obtains the target position of each microphone; wherein there are multiple driving devices, and each driving device corresponds to a microphone.

[0157] S105 , the processor controls the support frame and the plurality of driving devices to operate so as to drive each microphone to move to its corresponding target position.

[0158] Alternatively, a rectangular hexahedron measurement method can be used to measure the noise of the device under test. To do this, multiple sound collection points are deployed around the device under test. After each microphone reaches its corresponding reset point, the target position of each microphone is determined. The support frame and multiple drive mechanisms are then controlled to move each microphone to its corresponding target position. In this way, the microphones are distributed around the device under test to collect the sound emitted by the device.

[0159] Optionally, the target position of each microphone is determined by:

[0160] The processor obtains the size information and preset reference points of the device under test.

[0161] The processor determines the distance that each microphone needs to move on each axis based on the size information and the preset reference point.

[0162] The processor determines the target position of each microphone according to the reset point of each microphone and the distance that each microphone needs to move on each axis.

[0163] The device under test is placed in a pre-set position within the anechoic chamber, specifically below the support frame. A 3D scanner is used to scan the device's dimensions, including length, width, and height, to obtain the device's dimensions. Pre-set reference points are also obtained.

[0164] For devices of the same family with fixed dimensions, the position of each microphone relative to the device is fixed. For example, see Figure 20 When the preset reference points are not corrected, the positions that each microphone needs to reach are shown in Table 1:

[0165] Table 1 The positions that each microphone needs to reach

[0166]

[0167] Depend on Figure 20 It can be seen that the area of ​​the measurement surface S=2(2ac+2bc+bc).

[0168] The positions that each microphone needs to reach are defined as the original target points. Thus, based on the preset reference points and the original target points of each microphone, the distance that each microphone needs to move along each axis (X, Y, and Z) when moving from its respective preset reference points to its corresponding original target points can be calculated. The target positions of each microphone are then determined based on the reset points of each microphone and the distance each microphone needs to move along each axis. It will be appreciated that the target positions can be calculated based on the reset points and the distances required to move using existing algorithms, which will not be elaborated here. It can be seen that since the calculated distances that each microphone needs to move along each axis are fixed, if the preset reference points are modified, the target positions of each microphone will differ from the original target points. This allows for precise control of the actual sound positions collected by each microphone, thereby making the sound data collected by the microphones more accurate.

[0169] Optionally, at S105 , the processor controls the support frame and the plurality of driving devices to operate, including:

[0170] The processor controls the support frame and the X-axis driving device to operate so as to adjust the X-axis coordinate and the Z-axis coordinate of the X-axis microphone, thereby driving the X-axis microphone to move to its corresponding target position.

[0171] The processor controls the support frame, the X-axis drive device, and the Y-axis drive device to adjust the X-axis coordinate, the Y-axis coordinate, and the Z-axis coordinate of the Y-axis microphone, thereby driving the Y-axis microphone to move to the corresponding target position.

[0172] The processor controls the operation of the support frame, the X-axis drive device, the Y-axis drive device, and the Z-axis drive device to adjust the X-axis coordinate, the Y-axis coordinate, and the Z-axis coordinate of the Z-axis microphone, thereby driving the Z-axis microphone to move to the corresponding target position.

[0173] As can be seen from the structure of the system for controlling the position of the points described above, for the X-axis microphone, its movement on the X-axis can be achieved by the X-axis drive device, and its movement on the Z-axis can also be achieved by the hoisting device. Therefore, the support frame and the X-axis drive device can be controlled to operate to adjust the X-axis coordinate and Z-axis coordinate of the X-axis microphone, thereby driving the X-axis microphone to its corresponding target position. For the Y-axis microphone, its movement on the X-axis can be achieved by the X-axis drive device, its movement on the Y-axis can be achieved by the Y-axis drive device, and its movement on the Z-axis can also be achieved by the hoisting device. Therefore, the support frame, the X-axis drive device, and the Y-axis drive device can be controlled to operate to adjust the X-axis coordinate, Y-axis coordinate, and Z-axis coordinate of the Y-axis microphone, thereby driving the Y-axis microphone to its corresponding target position. For the Z-axis microphone, its movement on the X-axis can be achieved by the X-axis drive device, its movement on the Y-axis can be achieved by the Y-axis drive device, and its movement on the Z-axis can also be achieved by the hoisting device and the Z-axis drive device. Therefore, the support frame, X-axis drive device, Y-axis drive device and Z-axis drive device can be controlled to operate to adjust the X-axis coordinate, Y-axis coordinate and Z-axis coordinate of the Z-axis microphone, thereby driving the Z-axis microphone to move to the corresponding target position.

[0174] Combine Figure 21 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0175] S101: The processor obtains environmental parameters of a test environment.

[0176] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0177] S103: The processor controls the support frame and the driving device to operate so as to drive the microphone to a reset point.

[0178] S104: The processor obtains the target position of each microphone; wherein there are multiple driving devices, and each driving device corresponds to a microphone.

[0179] S105 , the processor controls the support frame and the plurality of driving devices to operate so as to drive each microphone to move to its corresponding target position.

[0180] S106, when controlling the operation of the plurality of driving devices, the processor obtains the position of each microphone and the tension of the harness of each sensor; wherein the system for controlling the point position further includes: a plurality of sensors, corresponding one-to-one to each microphone, for detecting the position of the corresponding microphone.

[0181] S107: The processor determines the point arrangement according to the position of each microphone and the tension of the wire harness of each sensor.

[0182] In the process of controlling the operation of multiple drive devices, it can be seen from the structure of the system mentioned above that when the first crossbeam and the fourth longitudinal beam move, the sensors (used to detect the positions of the corresponding microphones) provided thereon will be driven to move, and then the wiring harness of the sensor will be pulled out as the sensor moves. Before each sensor reaches its respective target position, the tension of the wiring harness of each sensor is obtained. A tension threshold is pre-stored in the memory. Optionally, the tension threshold takes a value of 10N. Each detected tension is compared with the tension threshold, and whether the tension applied to the wiring harness of each sensor is normal is determined based on the comparison result, and then the point layout is determined. In this way, during the operation of the control drive device, abnormal conditions such as jamming and entanglement of the wiring harness can be discovered in a timely manner, thereby ensuring that each microphone can be accurately moved to its respective target position.

[0183] Combine Figure 22 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0184] S101: The processor obtains environmental parameters of a test environment.

[0185] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0187] S104: The processor obtains the target position of each microphone; wherein there are multiple driving devices, and each driving device corresponds to a microphone.

[0188] S105 , the processor controls the support frame and the plurality of driving devices to operate so as to drive each microphone to move to its corresponding target position.

[0189] S106, when controlling the operation of the plurality of driving devices, the processor obtains the position of each microphone and the tension of the harness of each sensor; wherein the system for controlling the point position further includes: a plurality of sensors, corresponding one-to-one to each microphone, for detecting the position of the corresponding microphone.

[0190] S117, before each microphone reaches its corresponding target position: if the tension of the harness of each sensor is less than or equal to the tension threshold, then the processor determines that the point arrangement is completed when each microphone reaches its corresponding target position; if the tension of the harness of any sensor is greater than the tension threshold, then the processor reminds the user to release the harness of the corresponding sensor.

[0191] Before each microphone reaches its corresponding target position: If the tension of the harness of each sensor is less than or equal to the tension threshold, it means that the tension on the harness is within the normal range. Then when the microphone reaches its corresponding target position, it is determined that the point layout is complete. After that, the noise test of the device under test can be started. On the contrary, if the tension of the harness of each microphone detected is greater than the tension threshold, it means that the corresponding harness may have problems such as jamming and entanglement. The user is reminded to release the harness of the corresponding sensor. Specifically, the reminder information can be issued through the system's voice module, or the reminder information can be pushed to the user's smart terminal device.

[0192] Combine Figure 23 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0193] S101: The processor obtains environmental parameters of a test environment.

[0194] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0197] S105 , the processor controls the support frame and the plurality of driving devices to operate so as to drive each microphone to move to its corresponding target position.

[0198] S106, when controlling the operation of the plurality of driving devices, the processor obtains the position of each microphone and the tension of the harness of each sensor; wherein the system for controlling the point position further includes: a plurality of sensors, corresponding one-to-one to each microphone, for detecting the position of the corresponding microphone.

[0199] S117, before each microphone reaches its corresponding target position: if the tension of the harness of each sensor is less than or equal to the tension threshold, then the processor determines that the point arrangement is completed when each microphone reaches its corresponding target position; if the tension of the harness of any sensor is greater than the tension threshold, then the processor reminds the user to release the harness of the corresponding sensor.

[0200] S108: When the harness release satisfies a preset condition, the processor controls the system for controlling the point to shut down.

[0201] S109: The processor reminds the user to check.

[0202] After the user releases the corresponding harness, the system determines whether the harness release meets the preset conditions. If so, it indicates that the excessive tension on the harness has not been effectively resolved. The control point system is then shut down. A reminder message is then sent, and a push notification is sent to the user's smart terminal device to remind the user to check and eliminate any abnormalities in the harness. If not, it indicates that the harness is normal, and the control of the various drive units continues until each microphone moves to the target position, at which point the control unit is shut down.

[0203] Optionally, the harness release satisfies a preset condition, which is determined by:

[0204] The processor obtains the number of times the harness is released and the corresponding tension of the harness.

[0205] The processor determines that the release of the wire harness satisfies a preset condition when the wire harness is released continuously for a preset number of times and the tension of the corresponding wire harness is still greater than the tension threshold.

[0206] When the user releases the harness, the number of times the harness is released is recorded. The corresponding harness tension is also continuously monitored. If the harness is released a preset number of times and the corresponding harness tension remains greater than the tension threshold, the harness release is determined to have met the preset conditions, and the harness anomaly is determined to have not been effectively resolved. Optionally, the preset number of times is three.

[0207] Combine Figure 24 As shown, an embodiment of the present disclosure provides another method for controlling a point position, which is applied to the above-mentioned system for controlling a point position, and the method includes:

[0208] S101: The processor obtains environmental parameters of a test environment.

[0209] S102: The processor determines a reset point of the microphone according to environmental parameters.

[0210] S103: The processor controls the support frame and the driving device to operate so as to drive the microphone to a reset point.

[0214] S117, before each microphone reaches its corresponding target position: if the tension of the harness of each sensor is less than or equal to the tension threshold, then when each microphone reaches its corresponding target position, the point arrangement is determined to be complete; if any tension of the harness of each sensor is greater than the tension threshold, then the user is reminded to release the harness of the corresponding sensor.

[0215] S108: When the harness release satisfies a preset condition, the processor controls the system for controlling the point to shut down.

[0216] S109: The processor reminds the user to check.

[0217] S110: When the user has finished checking, the processor controls the support frame and the plurality of driving devices to operate so as to drive each microphone to move back to its corresponding reset point, and then executes S105.

[0218] After the control system shuts down and prompts the user to inspect, if the user has completed the inspection, the support frame and multiple drive devices are controlled to operate, reset the support frame and each drive device, and then move each microphone back to its corresponding reset point. The support frame and multiple drive devices are then controlled to operate, moving each microphone back to its corresponding target position. In this way, after the wiring harness anomaly is resolved, each microphone is first reset and then moved back to its target position, ensuring that the movement of each microphone is not affected by the previous wiring harness anomaly, thereby ensuring the accuracy of each microphone's position.

[0219] Combine Figure 25As shown, an embodiment of the present disclosure provides an apparatus 250 for controlling a position, comprising an acquisition module 2501, a determination module 2502, and a control module 2503. Acquisition module 2501 is configured to acquire environmental parameters of a test environment. Determination module 2502 is configured to determine a reset point for a microphone based on the environmental parameters. Control module 2503 is configured to control the operation of a support frame and a drive device to drive the microphone to the reset point.

[0220] Using the device 250 for controlling the position of points provided by the embodiment of the present disclosure, the environmental parameters of the test environment are first obtained. Based on the structure of the system for controlling the position of points, and in combination with the environmental parameters, the reset point of the microphone is determined. Based on the reset point, the support frame and the driving device are controlled to operate to drive the corresponding microphone to move on the X-axis, Y-axis and / or Z-axis, and then the corresponding microphone is moved to the reset point. In this way, the reset point of the microphone is adaptively adjusted based on the environmental parameters, which can make the target position of the microphone more accurate, and based on the system for controlling the position of points, the microphone coordinates can be arranged quickly, safely, efficiently, accurately, and fully automatically without manual operation.
