[0014] A high-precision equipment noise detection method includes the following steps: S1: First, connect the mobile phone to the control console wirelessly via a wireless transmission device. Then, connect the control console to the sound source locator, noise detector, and anemometer via a local area network. The mobile phone controls the detection equipment through corresponding mobile software. S2: Move the high-precision equipment to the testing area.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The noise source is located using a sound source locator. Once the noise source is identified, the adjustment mechanism is activated. A multi-section electric telescopic rod changes the height of the noise detector. A first motor drives a second gear via its output shaft, which in turn drives a rotating rod, causing the noise detector to rotate. Simultaneously, a third motor drives a second lead screw via its output shaft. During this rotation, the lead screw causes a first nut to slide on a fixed frame, which in turn causes a movable ring to slide on a support rod. The movable ring, via a first adjusting rod, changes the detection angle of the noise detector. The second motor, through its output shaft, also drives the first lead screw to rotate, which in turn moves the support rod on a connecting frame. This movement of the lead screw compensates for the adjusted position of the noise detector. The multi-section electric telescopic rod also adjusts the noise detector's height accordingly. After adjusting the height and angle of the noise detector, it performs the final measurement, improving accuracy and facilitating better noise assessment.
[0016] Move the equipment to the designated area. Based on the wind direction detected by the anemometer, rotate the movable rod to the leeward side. At this time, the fourth motor drives the third lead screw to rotate through the output shaft. The third lead screw drives the second nut to move on the moving vehicle through rotation. The second nut drives the movable rod and connecting rod to rotate on the moving vehicle through the second adjusting rod, thereby changing the angle of the cylinder. When the cylinder is perpendicular to the ground, the cylinder makes the connecting block contact the ground through the piston rod, improving the stability of the equipment.
[0017] The mobile phone can be wirelessly connected to the central control console via a wireless transmission device. The central control console can then be connected to the sound source locator, noise detector, and anemometer via a local area network. The mobile phone can control the testing equipment through corresponding mobile software, eliminating the need for on-site adjustment and control of the testing equipment. This avoids the testing personnel having to endure noise testing operations on-site and improves their comfort. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

An adjustment mechanism is provided on the surface of the shock-absorbing plate 52, which includes a multi-section electric telescopic rod 2. The electric telescopic rod 2 is fixedly connected to the surface of the shock-absorbing plate 52. A rotating rod 21 is rotatably connected to the telescopic end of the multi-section electric telescopic rod 2. A first gear 22 is fixedly connected to the surface of the rotating rod 21. A connecting frame 24 is fixedly connected to the top of the rotating rod 21. A first motor 25 is fixedly connected to the bottom of the connecting frame 24. A second gear 26 is fixedly connected to the piston rod of the first motor 25. A second motor 27 is fixedly connected to the surface of the connecting frame 24.

A fixed frame 3 is fixedly connected to the surface of the support rod 23. A third motor 31 is fixedly connected to the surface of the fixed frame 3. A second lead screw 32 is fixedly connected to the output shaft of the third motor 31. A first nut 33 is threadedly connected to the surface of the second lead screw 32. A movable ring 34 is fixedly connected to the surface of the first nut 33. A first adjusting rod 35 is rotatably connected to the surface of the movable ring 34. A detection device is set on the top of the support rod 23. The detection device includes a detection frame 4, which is rotatably connected to the surface of the support rod 23. A main control panel 41 is fixedly installed on the surface of the detection frame 4. A wireless transmission device 42 is fixedly installed on the surface of the main control panel 41. A sound source locator 43, a noise detector 44, and an anemometer 45 are fixedly installed on the surface of the detection frame 4. This high-precision device can adjust the height and angle of the noise detector 44 by locating the noise source, thereby improving the detection accuracy of the noise detector 44 and thus better assessing the noise.
[0022] Furthermore, a limiting mechanism is provided on the surface of the mobile vehicle 1. The limiting mechanism includes a first fixed block 6, which is fixedly connected to the surface of the mobile vehicle 1. A movable rod 61 is rotatably connected to the surface of the first fixed block 6. A connecting rod 62 is fixedly connected to the surface of the movable rod 61. A cylinder 63 is fixedly connected to the surface of the connecting rod 62. A connecting block 64 is fixedly connected to the piston rod of the cylinder 63. A second fixed block 65 is fixedly connected to the surface of the mobile vehicle 1. A fourth motor 67 is fixedly connected to the surface of the second fixed block 65. A third lead screw 66 is fixedly connected to the piston rod of the fourth motor 67. A second nut 68 is threadedly connected to the surface of the third lead screw 66. A second adjusting rod 69 is rotatably connected to the surface of the second nut 68. This limiting mechanism can lock the position of the high-precision equipment in the detection area, improve the stability of the high-precision equipment, and ensure the stability during the detection process.
[0023] Furthermore, the end of the shock-absorbing spring 5 furthest from the moving vehicle 1 is fixedly connected to the shock-absorbing plate 52. Two sets of shock-absorbing springs 5 and shock-absorbing plates 52 are provided. The telescopic damper 51 is sleeved inside the shock-absorbing spring 5. The shock-absorbing spring 5 and the moving vehicle 1 dampen the multi-section electric telescopic rod 2 through the shock-absorbing plate 52. The multi-section electric telescopic rod 2 then dampens the testing equipment through the support rod 23, reducing the vibration generated during the testing process and thus improving the stability of the testing equipment during the testing process.
[0024] Furthermore, the first gear 22 and the second gear 26 have the same diameter and mesh with each other. The second gear 26 is driven to rotate by the output shaft of the first motor 25. The second gear 26 drives the rotating rod 21 to rotate on the multi-section electric telescopic rod 2 through the first gear 22. The rotating rod 21 drives the support rod 23 to rotate through the connecting frame 24. The support rod 23 drives the detection equipment to rotate. The detection equipment changes the detection direction of the noise detector 44 by rotating, which makes it convenient for the user to adjust the detection direction of the noise detector 44 accordingly. The multi-section electric telescopic rod 2 drives the rotating rod 21 to rise and fall on the mobile vehicle 1 through the telescopic rod. The detection frame 4 has three telescopic rods. The rotating rod 21 drives the connecting frame 24 to rise and fall through the connecting frame 24. The connecting frame 24 drives the detection equipment to rise and fall on the mobile vehicle 1. At this time, the detection equipment changes the detection level of the noise detector 44 to facilitate noise detection on different horizontal planes.
[0025] Furthermore, the connecting frame 24 is U-shaped. The output shaft of the second motor 27 drives the first lead screw 28 to rotate on the connecting frame 24. The bottom of the support rod 23 has a threaded hole, and the first lead screw 28 is threadedly connected to the threaded hole at the bottom of the support rod 23. The first lead screw 28 drives the support rod 23 to slide on the surface of the connecting frame 24 by rotation. The support rod 23 drives the detection equipment to move synchronously, so that the detection equipment can move laterally. The lateral movement of the detection equipment is a compensation mechanism for angle adjustment. After the angle of the noise detector 44 is adjusted, it can ensure that the position of the noise detector 44 will not change, thereby ensuring the accuracy of the noise detector 44 in the detection process.
[0026] Furthermore, the fixed frame 3 is U-shaped. The third motor 31 drives the second lead screw 32 to rotate on the fixed frame 3 via the output shaft. The movable ring 34 is slidably connected to the surface of the support rod 23. The end of the first adjusting rod 35 away from the movable ring 34 is rotatably connected to the bottom of the detection frame 4. The second lead screw 32 drives the first nut 33 to slide and rise on the fixed frame 3 via rotation. The first nut 33 drives the movable ring 34 to rise and fall synchronously on the support rod 23. During the rising and falling process, the movable ring 34 drives the detection frame 4 to rotate on the top of the support rod 23 via the first adjusting rod 35. During the rotation of the detection frame 4, the angle of the entire detection equipment is changed, and the detection angle of the noise detector 44 is also changed. The change in the angle of the noise detector 44 will cause the position and height of the noise detector 44 to change accordingly. At this time, the support rod 23 will move laterally to compensate for the position of the noise detector 44. At the same time, the multi-section electric telescopic rod 2 will also drive the detection equipment to rise and fall to compensate for the height of the noise detector 44.
[0027] Furthermore, the main control console 41 and the wireless transmission device 42 are connected by electrical signals. The main control console 41 is equipped with a local area network (LAN) device. The main control console 41 is connected to the sound source locator 43 via a radio LAN. The main control console 41 is connected to the noise detector 44 via a LAN. The main control console 41 is connected to the anemometer 45 via a LAN. The main control console 41 is connected to the regulating mechanism via a LAN. The sound source locator 43, the noise detector 44, and the anemometer 45 all need to transmit data to the user's mobile phone through the main control console 41. The main control box 12 is equipped with a power supply. The power supply inside the main control box 12 is used to power the detection equipment. At the same time, the power supply also provides overall power to the regulating mechanism to ensure the normal operation of the equipment.
[0028] Furthermore, two sets of cylinders 63 and connecting blocks 64 are provided. Cylinders 63 and connecting blocks 64 rotate on the surface of the first fixed block 6 via movable rods 61 and connecting rods 62. Connecting blocks 64 move on connecting rods 62 via the piston rod of cylinders 63. The direction of movement of connecting blocks 64 is affected by the angle of movable rods 61. When movable rods 61 are parallel to the horizontal plane, the direction of movement of connecting blocks 64 is vertically downward. Connecting blocks 64 can not only improve the friction between the equipment and the ground, but also make the bottom support surface of high-precision equipment larger, thereby improving the stability of high-precision equipment during inspection.
[0029] Furthermore, the third lead screw 66 rotates on the second fixed block 65 via the output shaft of the fourth motor 67. The third lead screw 66 drives the second nut 68 to slide on the surface of the moving vehicle 1 through rotation. The end of the second adjusting rod 69 away from the second nut 68 is rotatably connected to the connecting rod 62. During the sliding process, the second nut 68 drives the connecting rod 62 and the movable rod 61 to rotate on the first fixed block 6 via the second adjusting rod 69. When the movable rod 61 rotates to be parallel to the horizontal plane, the cylinder 63 causes the connecting block 64 to move to contact and connect with the top surface via the piston rod.
[0030] A high-precision equipment noise detection method includes the following steps: S1: First, connect the mobile phone to the main control console 41 wirelessly via the wireless transmission device 42. Then, connect the main control console 41 to the sound source locator 43, the noise detector 44, and the anemometer 45 via a local area network. The mobile phone controls the detection equipment through the corresponding mobile phone software. S2: Move the high-precision equipment to the detection area. The anemometer 45 sends the wind speed data to the user's mobile phone through the central control console 41. The user adjusts the angle of the equipment according to the wind speed. Then, the limit mechanism is activated to position the high-precision equipment to avoid positional deviation during the detection process. S3: The sound source locator 43 is started by controlling the main control console 41 to locate and sense the surrounding noise, determine the source of the surrounding noise, and output the detection data to the user's mobile phone through the main control console 41. S4: Adjust the position and detection angle of the mobile vehicle 1 through the adjustment mechanism to ensure detection accuracy, and then start the noise detector 44 through the main control panel 41 to perform noise detection. S5: The noise detector 44 outputs the detected noise data to the user's mobile phone through the central control console 41. When the detection is over, the central control console 41 will send a completion signal to the user's mobile phone to remind the user to recycle the equipment. S6: Used to reach the detection area, retract the limiting mechanism of the high-precision detection equipment, and then bring the high-precision detection equipment back for convenient use next time.
[0031] Working principle: The equipment is moved to a designated area. Based on the wind direction detected by the anemometer 45, the movable rod 61 is rotated to the leeward side. At this time, the fourth motor 67 drives the third lead screw 66 to rotate via its output shaft. The third lead screw 66, through rotation, drives the second nut 68 to move on the moving carriage 1. The second nut 68, through the second adjusting rod 69, drives the movable rod 61 and connecting rod 62 to rotate on the moving carriage 1, thereby changing the angle of the cylinder 63. When the cylinder 63 is perpendicular to the ground, the cylinder 63, through the piston rod, causes the connecting block 64 to contact the ground, improving the stability of the equipment. Then, the sound source locator 43 locates the sound source. After identifying the noise source, the adjustment mechanism is activated. The multi-section electric telescopic rod 2 changes the height of the noise detector 44 via the telescopic rod. The first motor 25 drives the second gear 26 to rotate via its output shaft. The second gear 26, through the first gear 22, drives the rotating rod 21 to rotate, thereby... The detection equipment drives the noise detector 44 to rotate. Simultaneously, the third motor 31 drives the second lead screw 32 to rotate via its output shaft. During the rotation of the second lead screw 32, the first nut 33 slides on the fixed frame 3. The first nut 33 drives the movable ring 34 to slide on the support rod 23. The movable ring 34 changes the detection angle of the noise detector 44 via the first adjusting rod 35. At the same time, the second motor 27 drives the first lead screw 28 to rotate via its output shaft. The first lead screw 28 drives the support rod 23 to move on the connecting frame 24 through rotation. The movement of the first lead screw 28 compensates for the position of the noise detector 44 after the angle adjustment. At the same time, the multi-section electric telescopic rod 2 also drives the noise detector 44 to rise and fall to perform corresponding height compensation. After the height and angle of the noise detector 44 are adjusted, the noise detector 44 performs detection again, which improves the accuracy of detection and facilitates better noise assessment.
