Description

Technical Field

[0001] This invention relates to the field of road noise monitoring technology, and more specifically to a road noise monitoring device. Background Technology

[0002] Road noise refers to the sound generated by vehicles during operation that disrupts people's normal life and work. It generally refers to the noise produced by motor vehicles driving in cities, and its sound level varies with time and other factors. Road noise monitoring equipment is a specialized device used to monitor road noise. Existing urban road noise monitoring equipment mainly uses a condenser electret microphone within its probe, which is sensitive to sound. Sound waves cause the electret diaphragm inside the microphone to vibrate, causing a change in the capacitor and generating a corresponding small voltage, thus converting the sound signal into an electrical signal. This is then fixedly installed in a chassis or other structure and placed in the road environment. Traditional road noise monitoring devices typically consist of a sound level meter, a data acquisition and control unit, and a transmission unit. They monitor the sound of vehicles traveling on the road, collecting data such as the average noise level in decibels over a given time period. However, because this type of noise monitoring only collects the average value while vehicles are in motion, it cannot accurately monitor the noise generated by a single vehicle when multiple vehicles are traveling along the road. Furthermore, it cannot accurately identify vehicle noise when there is excessive noise such as vehicle horns or in sudden situations, making it difficult to collect evidence later. Summary of the Invention

[0003] The purpose of this invention is to provide a road noise monitoring device that can achieve a sequential sliding and ejection process through a buried pre-embedded cable tray and a loop track in conjunction with three sets of noise monitoring frames. This allows for the tracking and monitoring of decelerated road vehicles within a certain distance. By sequentially and cyclically sorting the vehicles, the device completes the individual monitoring process for each passing vehicle, enabling the backup and accurate monitoring and recording of data such as the model and noise level of each vehicle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A road noise monitoring device includes a linkage photographing mechanism, a tracking monitoring mechanism, a built-in charging mechanism, and a pre-embedded wiring mechanism. The linkage photographing mechanism is installed on the ground. One side of the linkage photographing mechanism is connected to the tracking monitoring mechanism. The built-in charging mechanism is installed inside the tracking monitoring mechanism. The pre-embedded wiring mechanism is connected to one end of the linkage photographing mechanism. The tracking monitoring mechanism includes a pre-embedded cable tray, a loop track, a launcher, a climbing launcher group, a resetting launcher group, a noise monitoring frame, a shaft frame, and a charging buckle. Loop tracks are distributed on both sides of the inner wall of the pre-embedded cable tray. A launcher is installed at one end of the loop track. A motor is installed inside the launcher. A wheel is connected to one side of the motor. A striker is connected to one side of the wheel. A climbing launcher group is installed at one end of the bottom of the pre-embedded cable tray. A resetting launcher group is distributed at the other end of the pre-embedded cable tray. A noise monitoring frame is attached to the inner wall of the loop track. A impact pad is fixed to the outer wall of the noise monitoring frame. A shaft frame is connected to both sides of the noise monitoring frame. A charging buckle is engaged on one side of the middle of the shaft frame.

[0006] Furthermore, the noise monitoring frame is configured as a sliding structure by means of a shaft frame and the loop-shaped rails on both sides of the inner wall of the pre-embedded cable tray, and three sets of noise monitoring frames are installed in the loop-shaped rails.

[0007] Furthermore, one side of the shaft frame engages with the charging buckle, and the charging buckle is connected to the catapult pile, the climbing catapult group, the reset catapult group, and the pre-embedded wiring mechanism.

[0008] Furthermore, the linkage photography mechanism includes a speed bump, a belt plate, a ramp frame, a camera assembly, a linkage plate, and a weighing sensor. A belt plate is installed at the middle of the bottom end of the speed bump, a ramp frame is distributed on the top surface of the speed bump, and a camera assembly is embedded inside the ramp frame. Linkage plates are distributed on both sides of the ramp frame, and a weighing sensor is installed at the bottom of the linkage plate. The linkage plate and the weighing sensor are symmetrically distributed along both ends of the speed bump, and the ramp frame and the camera assembly are fixedly connected to the speed bump.

[0009] Furthermore, the built-in charging mechanism includes a microphone slot, an electret microphone, a wireless transmission module, a battery module, and a charging port. The electret microphone is located inside the microphone slot, the wireless transmission module is located at the bottom of the electret microphone, and the battery module, which provides a charging power source, is located at the bottom of the wireless transmission module. Charging ports are distributed on both sides of the battery module.

[0010] Furthermore, the battery module is connected to the charging port and the wireless transmission module, and the microphone slot is fixedly connected to the electret microphone and the tracking and monitoring mechanism.

[0011] Furthermore, the pre-embedded wiring mechanism includes a pre-embedded box, a wireless receiving module, a processor module, and a wiring trough. The processor module is installed inside the pre-embedded box, and the wiring trough is installed on both sides of the pre-embedded box and connected to the pre-embedded box.

[0012] Furthermore, the pre-embedded box and the wiring groove are fixedly connected, and the wiring groove is connected to the linkage photography mechanism and the tracking and monitoring mechanism.

[0013] A method for operating a road noise monitoring device includes the following steps:

[0014] S1: The speed bump and tracking monitoring device are pre-buried in the traffic section that needs to be monitored, and the pre-buried wiring device is pre-buried to connect and install the speed bump and tracking monitoring device.

[0015] S2: When the vehicle's tires hit the speed bump, the vehicle slows down and simultaneously contacts the linkage plates on both sides of the speed bump. At this time, the weighing sensor at the bottom of the linkage plate is triggered. The weighing sensor is connected to the processor module, which controls the camera component to take pictures of the vehicle that has passed over the speed bump. At the same time, the timer inside the pre-embedded box records the corresponding shooting time.

[0016] S3: When the linkage plate and weighing sensor are triggered, the processor module controls the operation of the ejector pile, which impacts the impact pad of the noise monitoring frame on one side. At this time, the decelerated car reaches the position of the pre-embedded bridge frame and continues to drive. The impacted noise monitoring frame slides along the loop track to the other end of the pre-embedded bridge frame. During the sliding process, the noise monitoring frame moves to merge with the single vehicle in the direction it is facing and performs noise monitoring.

[0017] S4: When subsequent vehicles arrive, the processor module operates the climbing catapult group to impact upwards, causing the second noise monitoring frame to climb upwards and engage with the charging buckle. At the same time, the catapult pile continues to impact the second noise monitoring frame to track and monitor the subsequent vehicles. At this time, the third noise monitoring frame at the other end of the pre-embedded bridge frame is launched to the position of the climbing catapult group by the bottom reset catapult group. The first noise monitoring frame that has completed the monitoring process enters the original position of the third noise monitoring frame along the loop track, and so on to form a cyclic sliding monitoring.

[0018] S5: During the sliding monitoring process of the noise monitoring frame, the sound receiving slot at the top of the noise monitoring frame monitors the noise of the movement through the internal electret microphone, and transmits the side monitoring information to the wireless receiving module through the wireless transmission module connected at the bottom.

[0019] S6: The wireless receiving module inside the pre-embedded box receives the noise monitoring data transmitted by the wireless transmission module, and performs judgment and measurement in conjunction with the processor module. The wireless receiving module inside the pre-embedded box transmits the noise data and image data of multiple vehicles to the cloud for processing and recording.

[0020] The beneficial effects of this invention are as follows: Compared with existing road noise monitoring equipment, the road noise monitoring device provided by this invention has the following characteristics and advantages:

[0021] 1. This invention utilizes a buried pre-embedded cable tray and a loop track in conjunction with three sets of noise monitoring frames to achieve a sequential sliding ejection process. This allows for the tracking and monitoring of vehicles on the road after deceleration within a certain distance. The process of monitoring each passing vehicle is completed through a cyclical, sequential sequence. The monitoring data and photo capture sequence are recorded simultaneously and transmitted to the cloud for processing. Data such as the model of each vehicle and its noise status are backed up and accurately recorded. This device has a wide range of applications and can monitor various road conditions and noises such as vehicle horns, down to each vehicle within the monitoring range, with more precise monitoring data. The processor module operates the camera component to take pictures of vehicles driving over speed bumps, and simultaneously, the timer inside the pre-embedded box records the corresponding shooting time. Then, the noise of driving within this road section is tracked and monitored. The weighing sensor triggers the photo capture to lock onto the driving vehicle, and the tracking noise monitoring achieves a high-precision monitoring process of the sound and image of a single vehicle driving.

[0022] 2. The present invention has a battery module installed inside the bottom of the noise monitoring frame, which can maintain the stability of the center of gravity of the overall frame structure. The battery module supplies power to the connected wireless transmission module and electret microphone. When the noise monitoring frame is not in use or when the charging ports on both sides are in contact with the charging buckle, the charging ports and battery module will be charged through the charging buckle, thus providing power replenishment for the noise monitoring frame.

[0023] 3. The wireless receiving module inside the pre-embedded box in this invention can receive the monitored noise monitoring data, and perform judgment and measurement in conjunction with the processor module. Then, the noise data and the image data are transmitted to the cloud for processing and recording through the processor module and wireless receiving module inside the pre-embedded box, providing the functions of organizing and transmitting monitoring data, and maintaining the stable operation of the overall device.

[0035] To address the limitations of existing methods that cannot accurately monitor noise from a single vehicle when multiple vehicles are traveling along a road, and the inability to accurately identify vehicle noise levels when there are excessive noises such as horns or sudden incidents, thus hindering subsequent evidence collection, the following solution is provided in the instruction manual. Figure 1As shown, the present invention provides a road noise monitoring device, which includes a linkage photographing mechanism 1; a tracking monitoring mechanism 2 is connected to one side of the linkage photographing mechanism 1, and a built-in charging mechanism 3 for charging is provided inside the tracking monitoring mechanism 2; one end of the linkage photographing mechanism 1 is connected to a pre-embedded wiring mechanism 4; the linkage photographing mechanism 1 includes a speed bump 101, a belt plate 102, a ramp frame 103, a camera assembly 104, a linkage plate 105, and a weighing sensor 106; the belt plate 102 is installed in the middle of the bottom end of the speed bump 101; the ramp frame 103 is distributed on the top surface of the speed bump 101; the camera assembly 104 for taking pictures is embedded inside the ramp frame 103; the linkage plates 105 are distributed on both sides of the ramp frame 103; and the weighing sensor 106 is provided at the bottom of the linkage plate 105; the linkage plate 105 and the weighing sensor 106 are symmetrically distributed along both ends of the speed bump 101; the ramp frame 103 and the camera assembly 104 are fixedly connected to the speed bump 101. Before using the monitoring device, the speed bump 101 and the tracking monitoring mechanism 2 need to be pre-embedded in the traffic section to be monitored. The pre-embedded wiring mechanism 4 is pre-embedded and connected to the speed bump 101 and the tracking monitoring mechanism 2. The speed bump 101 is laid horizontally on the road surface, and the pre-embedded bridge 201 is laid along the edge of the lane. During driving, the tires of the vehicle slow down when they hit the speed bump 101 and simultaneously contact the linkage plates 105 on both sides of the speed bump 101. At this time, the weighing sensor 106 at the bottom of the linkage plate 105 is triggered. The weighing sensor 106 is connected to the processor module 403, and the processor module 403 operates the camera component 104 to take pictures of the vehicle that has passed over the speed bump 101. At the same time, the timer installed inside the pre-embedded box 401 records the corresponding shooting time. Then, the driving noise in this section is tracked and monitored. This structure uses the weighing sensor 106 to trigger the shooting and lock the driving vehicle. Combined with the tracking noise monitoring, it realizes a high-precision monitoring process of the sound and image of a single vehicle driving.

[0036] As per the specification attached to this invention Figure 3 Instruction manual attached Figure 4 Instruction manual attached Figure 5 and instruction manual attached Figure 6As shown, the tracking and monitoring mechanism 2 of this invention includes a pre-embedded cable tray 201, a loop track 202, a catapult 203, a motor 204, a rotating wheel 205, a linkage rod 206, a firing pin 207, a climbing catapult assembly 208, a resetting catapult assembly 209, a noise monitoring frame 210, an impact pad 211, a shaft frame 212, and a charging buckle 213. Loop tracks 202 are distributed on both sides of the inner wall of the pre-embedded cable tray 201. A catapult 203 for performing catapult operations is set at one end of the loop track 202. A motor 204 is installed inside the catapult 203, and a rotating wheel 205 is connected to one side of the motor 204. A firing pin 207 is connected to one side of the rotating wheel 205. A climbing catapult assembly 208 is set at one bottom end of the pre-embedded cable tray 201. At the other end of 01, a reset ejection assembly 209 is distributed. A noise monitoring frame 210 is attached to the inner wall of the loop track 202. An impact pad 211 is fixed to the outer wall of the noise monitoring frame 210. A shaft frame 212 is connected to both sides of the noise monitoring frame 210. A charging buckle 213 is engaged on one side of the middle end of the shaft frame 212. The noise monitoring frame 210 forms a sliding structure with the loop track 202 on both sides of the inner wall of the pre-embedded cable tray 201 through the shaft frame 212. Three sets of cyclically working noise monitoring frames 210 are set on the loop track 202. One side of the shaft frame 212 is engaged with the charging buckle 213. The charging buckle 213, the ejection pile 203, the climbing ejection assembly 208, and the reset ejection assembly 209 are connected to the pre-embedded wiring mechanism 4 to perform the pre-embedding of the pre-embedded cable tray 201. When the top surface of the pre-embedded cable tray 201 is flush with the road surface, and the linkage plate 105 and the weighing sensor 106 are triggered, the processor module 403 operates the ejector pile 203 to impact the impact pad 211 of the noise monitoring frame 210 on one side. At this time, the decelerated car reaches the position of the pre-embedded cable tray 201 and continues to drive. The impacted noise monitoring frame 210 slides along the loop track 202 to the other end of the pre-embedded cable tray 201. During the sliding process, the noise monitoring frame 210 moves to merge with the single vehicle facing it, completing the noise monitoring and data collection process. If the vehicle continues to drive, the processor module 403 operates the climbing ejector group 208 to impact upwards, so that the second group of noise monitoring frames 210 As the vehicle climbs upwards and engages with the charging clip 213, the ejector pile 203 continues to impact the second set of noise monitoring frames 210 as subsequent vehicles are tracked and monitored. At this time, the third set of noise monitoring frames 210 at the other end of the pre-embedded cable tray 201 is ejected by the bottom reset ejector group 209 to the position of the climbing ejector group 208. Meanwhile, the first set of noise monitoring frames 210, having completed the monitoring process, moves along the loop track 202 to the original position of the third set of noise monitoring frames 210, and so on, completing the cyclic sliding monitoring. This, in conjunction with the deceleration and photography structure, enables uninterrupted noise tracking and monitoring of vehicles traveling in a side position.

This device has wide applications, monitoring various road conditions and vehicle noise such as horns, down to each vehicle within the monitoring range, providing more precise data. When the launcher 203 operates, the motor 204 drives the rotating wheel 205 to rotate. The rotating wheel 205 drives the connected linkage rod 206 to extend and retract the striker 207, which completes the continuous launch process.

The wireless transmission module 303 is located at the bottom of the electret microphone 302, and the battery module 304 is located at the bottom of the wireless transmission module 303. Charging ports 305 are distributed on both sides of the battery module 304. The battery module 304 is connected to the charging port 305 and the wireless transmission module 303. The microphone slot 301 is fixedly connected to the electret microphone 302 and the tracking and monitoring mechanism 2. During the sliding monitoring process of the noise monitoring frame 210, the microphone slot 301 at the top of the noise monitoring frame 210 transmits power through the internal electret microphone 302. 02. The noise during driving is monitored, and then measured and judged by the sound level meter module connected to the electret microphone 302. The side monitoring information is transmitted to the wireless receiving module 402 through the wireless transmission module 303 connected to the bottom, and collected to the cloud by the processor module 403. The battery module 304 is installed inside the bottom of the noise monitoring frame 210. The battery module 304 can provide a charging power and maintain the stability of the center of gravity of the overall frame structure. When in use, the battery module 304 supplies power to the connected wireless transmission module 303 and electret microphone 302. When the noise monitoring frame 210 is not in use or when the charging ports 305 on both sides are in contact with the charging buckle 213, the charging ports 305 and battery module 304 will be charged through the charging buckle 213, thus providing power replenishment for the noise monitoring frame 210.

[0038] As per the specification attached to this invention Figure 8As shown, the pre-embedded wiring mechanism 4 of this invention includes a pre-embedded box 401, a wireless receiving module 402, a processor module 403, and a wiring slot 404. The processor module 403 is housed inside the pre-embedded box 401, and wiring slots 404 are connected to both sides of the pre-embedded box 401. The pre-embedded box 401 and wiring slots 404 are fixedly connected, and the wiring slots 404 are connected to the linkage photographing mechanism 1 and the tracking and monitoring mechanism 2. Before the pre-embedded box 401 and wiring slots 404 are buried in the road to be installed, this... The two ends of the wiring groove 404 are in close contact with the ends of the pre-buried speed bump 101 and the tracking and monitoring mechanism 2 to facilitate wiring during the pre-buried process. After the wiring is completed, the power supply box module inside the pre-buried box 401 connects the buried cable to the power supply. The wireless receiving module 402 inside the pre-buried box 401 can receive the monitored noise data and make judgments in conjunction with the processor module 403. Then, the noise data and the image data are transmitted to the cloud for processing and recording through the wireless receiving module 402 inside the pre-buried box 401.

[0039] The working method of the road noise monitoring device of the present invention includes the following steps:

[0040] S1: First, the speed bump 101 and the tracking and monitoring mechanism 2 are buried in advance in the traffic section to be monitored, and the pre-buried wiring mechanism 4 is pre-buried and connected to the speed bump 101 and the tracking and monitoring mechanism 2.

[0041] S2: When the vehicle tires decelerate when they hit the speed bump 101, they simultaneously contact the linkage plates 105 on both sides of the speed bump 101. At this time, the weighing sensor 106 at the bottom of the linkage plate 105 is triggered. The weighing sensor 106 is connected to the processor module 403, and the processor module 403 operates the camera assembly 104 to take pictures of the vehicle that has passed over the speed bump 101. At the same time, the timer installed inside the pre-embedded box 401 records the corresponding shooting time.

[0042] S3: When the linkage plate 105 and the weighing sensor 106 are triggered, the ejector pile 203 is operated by the processor module 403. The ejector pile 203 impacts the impact pad 211 of the noise monitoring frame 210 on one side. At this time, the car that has been slowed down reaches the position of the pre-embedded bridge frame 201 and continues to drive. The impacted noise monitoring frame 210 is ejected and slid along the loop track 202 to the other end of the pre-embedded bridge frame 201. During the sliding process, the noise monitoring frame 210 moves to merge with the single vehicle in the direction it is facing and performs noise monitoring.

[0043] S4: When subsequent vehicles arrive, the processor module 403 operates the climbing ejection group 208 to impact upwards, causing the second noise monitoring frame 210 to climb upwards and engage with the charging buckle 213. At the same time, the ejection pile 203 continues to impact the second noise monitoring frame 210 to track and monitor the subsequent vehicles. At this time, the third noise monitoring frame 210 at the other end of the pre-embedded bridge frame 201 is ejected by the bottom reset ejection group 209 to the position of the climbing ejection group 208. The first noise monitoring frame 210 that has completed the monitoring process enters the original position of the third noise monitoring frame 210 along the loop track 202, and so on to form a cyclic sliding monitoring.

[0044] S5: During the sliding monitoring process of the noise monitoring frame 210, the sound receiving slot 301 at the top of the noise monitoring frame 210 monitors the noise of the vehicle through the internal electret microphone 302, and transmits the side monitoring information to the wireless receiving module 402 through the wireless transmission module 303 connected at the bottom.

[0045] S6: The noise monitoring data transmitted by the wireless transmission module 303 is received by the wireless receiving module 402 installed in the pre-embedded box 401, and the processor module 403 is used to make judgments and measurements. The noise data and image data of multiple vehicles are transmitted to the cloud for processing and recording through the wireless receiving module 402 inside the pre-embedded box 401.

The electret microphone (302) is installed inside the microphone slot (301). The wireless transmission module (303) is installed at the bottom of the electret microphone (302). The battery module (304) is installed at the bottom of the wireless transmission module (303). The charging ports (305) are distributed on both sides of the battery module (304).

6. A road noise monitoring device according to claim 5, characterized in that, The battery module (304) is connected to the charging port (305) and the wireless transmission module (303), and the sound receiving slot (301) is fixedly connected to the electret microphone (302) and the tracking and monitoring mechanism (2).

7. A road noise monitoring device according to claim 5, characterized in that, The pre-embedded wiring mechanism (4) includes a pre-embedded box (401), a wireless receiving module (402), a processor module (403), and a wiring slot (404). The processor module (403) is installed inside the pre-embedded box (401), and the wiring slots (404) are connected to both sides of the pre-embedded box (401). The pre-embedded box (401) and the wiring slots (404) are fixedly connected, and the wiring slots (404) are connected to the linkage photography mechanism (1) and the tracking and monitoring mechanism (2).

8. A method for operating the road noise monitoring device according to claim 1, characterized in that, The steps include: S1: The speed bump (101) and the tracking and monitoring mechanism (2) are buried in advance in the traffic section that needs to be monitored, and the speed bump (101) and the tracking and monitoring mechanism (2) are connected and installed in advance by the pre-buried wiring mechanism (4); S2: When the tires of the vehicle run over the speed bump (101), the vehicle slows down and simultaneously contacts the linkage plates (105) on both sides of the speed bump (101). At this time, the weighing sensor (106) at the bottom of the linkage plate (105) is triggered. The weighing sensor (106) is connected to the processor module (403), and the processor module (403) controls the operation camera assembly (104) to start taking pictures of the vehicle that runs over the speed bump (101). At the same time, the timing device installed inside the pre-embedded box (401) records the corresponding shooting time. S3: When the linkage plate (105) and the weighing sensor (106) are triggered, the processor module (403) controls the operation of the ejector pile (203), which impacts the impact pad (211) of the noise monitoring frame (210) on one side. At this time, the car, after being decelerated, reaches the position of the pre-embedded bridge frame (201) and continues to drive. The impacted noise monitoring frame (210) slides along the loop track (202) to the other end of the pre-embedded bridge frame (201). During the sliding process, the noise monitoring frame (210) moves to the lane of the single vehicle and performs noise monitoring. S4: When subsequent vehicles arrive, the processor module (403) operates the climbing catapult group (208) to impact upwards, causing the second noise monitoring frame (210) to climb upwards and engage with the charging buckle (213). At the same time, the catapult pile (203) continues to impact the second noise monitoring frame (210) as the subsequent vehicles are tracked and monitored. At this time, the third noise monitoring frame (210) at the other end of the pre-embedded bridge frame (201) is launched to the position of the climbing catapult group (208) by the bottom reset catapult group (209). The first noise monitoring frame (210) that has completed the monitoring process enters the original position of the third noise monitoring frame (210) along the loop track (202), and so on to form a cyclic sliding monitoring. S5: During the sliding monitoring process of the noise monitoring frame (210), the sound receiving slot (301) at the top of the noise monitoring frame (210) monitors the noise of the vehicle through the internal electret microphone (302), and transmits the side monitoring information to the wireless receiving module (402) through the wireless transmission module (303) connected at the bottom. S6: The noise monitoring data transmitted by the wireless transmission module (303) is received by the wireless receiving module (402) installed in the pre-embedded box (401), and the processor module (403) performs judgment and measurement. The noise data and image data of multiple vehicles are transmitted to the cloud for processing and recording through the wireless receiving module (402) inside the pre-embedded box (401).
