[0026] 1. When the direction of the noise detector needs to be adjusted, pull the movable sleeve upwards. The thrust spring is compressed, and the bottom of the movable sleeve disengages from the limit sleeve. Then rotate the support plate, and the rotating rod rotates freely within the top of the support. When the desired direction is reached, release the movable sleeve. The thrust spring will return to its original deformation and push the movable sleeve to re-engage with the top of the limit sleeve, thus locking the direction.

[0027] 2. By rotating the rotating disk at the top of the threaded rod, the threaded rod can be driven to rotate and rise or fall within the limit frame. As the threaded rod descends, the pressure plate connected to its bottom will also descend and make contact with the top of the noise identification device through the rubber pad. Further rotation of the rotating disk will cause the pressure plate to press the noise identification device more tightly onto the support pad, ensuring the stability of the noise identification device during operation and reducing movement or tilting caused by vibration or external force.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figure 1-3 A noise recognition and classification instrument based on artificial intelligence includes a support 1, a limiting sleeve 2 fixedly connected to the top of the support 1, and a rotating rod 3 rotatably connected to the middle of the top of the support 1. The rotating rod 3 passes through the limiting sleeve 2 and extends to the top of the limiting sleeve 2.
[0036] A fixed ring 4 is fixedly sleeved on the outer surface of the rotating rod 3, and a thrust spring 5 and a movable sleeve 7 are movably sleeved on the outer surface of the rotating rod 3. The thrust spring 5 is located between the fixed ring 4 and the movable sleeve 7. The top of the thrust spring 5 abuts against the bottom of the fixed ring 4, and the bottom of the thrust spring 5 abuts against the top of the movable sleeve 7. The bottom of the movable sleeve 7 is engaged with the top of the limiting sleeve 2.
[0037] A support plate 8 is fixedly connected to the top of the rotating rod 3, and a noise identification device 10 is connected to the top of the support plate 8. The direction of the noise identification device 10 can be flexibly adjusted as needed to adapt to the noise monitoring needs in different environments, thereby improving the accuracy and targeting of noise identification, especially in situations where directional monitoring is required.
[0038] A collar 6 is fixedly fitted onto the outer surface of the movable sleeve 7, and arc-shaped grooves are equidistantly arranged on the outer surface of the collar 6. A circumferentially equidistant groove is formed on the top of the limiting sleeve 2, and a circumferentially equidistant locking block is fixedly connected to the bottom of the movable sleeve 7, engaging inside the groove. This allows the movable sleeve 7 to be securely fixed to the limiting sleeve 2, thereby ensuring the stability of the noise recognition device 10's position positioning.
[0039] A limiting frame 9 is fixedly connected to the top of the support plate 8, and the noise detector 10 is placed inside the limiting frame 9. A support pad 11 is fixedly connected to the top of the support plate 8, and the bottom of the noise detector 10 is placed on top of the support pad 11. The support pad 11 is located between the noise detector 10 and the support plate 8, and plays a role in buffering and shock absorption. When the equipment is subjected to external impact or vibration, the support pad 11 can absorb some energy, reduce the impact of these forces on the precision components inside the noise detector 10, and protect it from damage.
[0040] A threaded rod 12 is threadedly connected to the center of the top of the limiting frame 9. The bottom of the threaded rod 12 extends into the interior of the limiting frame 9, and a pressure plate 13 is rotatably connected to the bottom of the threaded rod 12. A rubber pad is fixedly connected to the bottom of the pressure plate 13, and the bottom of the rubber pad abuts against the top of the noise detector 10. The top of the threaded rod 12 extends to the top of the limiting frame 9, and a rotating disk 14 is fixedly connected to the top of the threaded rod 12. By rotating the rotating disk 14 at the top of the threaded rod 12, the threaded rod 12 can be rotated and raised or lowered within the limiting frame 9. As the threaded rod 12 lowers, the pressure plate 13 connected to its bottom also lowers, and makes contact with the top of the noise detector 10 through the rubber pad. Further rotation of the rotating disk 14 and the pressure plate 13 press the noise detector 10 more tightly onto the support pad 11, ensuring the stability of the noise detector 10 during operation and reducing movement or tilting caused by vibration or external forces.
[0041] A tripod 15 is connected to the bottom of the support 1. The tripod 15 allows the noise detector 10 to better adapt to different terrains and ground conditions, making it easier to fix and use the noise detector 10.
[0042] Please see Figure 4 An artificial intelligence-based noise recognition and classification instrument further includes: microphone I 16, microphone II 17, power supply module 19, radio frequency communication module 20, noise classification module 21, MCU chip 18, and clock circuit 22. Microphone I 16 is connected to one side of the noise recognition instrument 10 and is used to collect noise. Microphone II 17 is connected to the other side of the noise recognition instrument 10 and is used to collect noise. By collecting noise from both sides of the noise recognition instrument 10 through the two microphones (microphone I 16 and microphone II 17), noise information from both sides, including the direction and intensity of the sound source, can be obtained.
[0043] Power module 19 provides power for the noise identification device 10. Power module 19 is electrically connected to microphone I 16, microphone II 17, RF communication module 20 and MCU chip 18. Power module 19 provides stable power to components such as noise identification device 10, microphone I 16, microphone II 17, RF communication module 20 and MCU chip 18. RF communication module 20 is used to transmit noise data to the outside world. RF communication module 20 is electrically connected to the SPI terminal of MCU chip 18. RF communication module 20 can wirelessly transmit the noise data processed by noise classification module 21 to external devices or systems, such as data centers, monitoring centers, etc.
[0044] The noise classification module 21 is used to classify the characteristics of noise. The noise classification module 21 extracts useful feature information from the noise signal, such as frequency, amplitude, and duration, and classifies and identifies the noise based on the extracted feature information, such as traffic noise, industrial noise, and residential noise. The MCU chip 18 is installed inside the noise identification instrument 10. The MCU chip 18 is used to receive data signals from microphone I 16, microphone II 17 and the noise classification module 21, and determines whether to control the radio frequency communication module 20 to send noise data signals to the outside world based on the detection results. The clock circuit 22 is used to detect the working time of the MCU chip 18. The clock circuit 22 is electrically connected to the MCU chip 18. The noise identification instrument 10 also has a built-in artificial intelligence algorithm that can collect and analyze noise signals in real time, quickly and accurately identify the type and source of noise, improve the efficiency and accuracy of noise monitoring, and provide strong technical support for noise control and management.
[0045] Working principle: The noise identification device 10 is placed inside the limiting frame 9. The rotating disk 14 at the top of the threaded rod 12 can drive the threaded rod 12 to rotate and rise or fall within the limiting frame 9. As the threaded rod 12 falls, the pressure plate 13 connected to its bottom also falls and comes into contact with the top of the noise identification device 10 through the rubber pad. Further rotating the rotating disk 14, the pressure plate 13 presses the noise identification device 10 more tightly onto the support pad 11.
[0046] When the direction of the noise identification device 10 needs to be adjusted, pull the movable sleeve 7 upward, the thrust spring 5 is compressed, the bottom of the movable sleeve 7 is disengaged from the limiting sleeve 2, and then rotate the support plate 8, the rotating rod 3 rotates freely in the top of the support 1.
[0047] Once the desired direction is reached, the movable sleeve 7 is released, and the thrust spring 5 returns to its original deformation, pushing the movable sleeve 7 to re-engage with the top of the limit sleeve 2, thus locking the direction. The direction of the noise detector 10 can be flexibly adjusted as needed to adapt to the noise monitoring requirements in different environments, improving the accuracy and targeting of noise identification, especially in situations requiring directional monitoring.
