Description

Technical Field

[0001] The present application relates to the technical field of traffic control, and in particular to a non-site law enforcement device for technological overweight control. Background Art

[0002] Road transportation plays a vital role. Illegally produced and modified vehicles continue to proliferate, and safety hazards such as overloading and overlimit are always threatening the safety of roads and people's lives. According to statistics, more than 80% of road traffic accidents involving heavy trucks are caused by overloading, and 30% of bridge collapse accidents also originate from this. Overloading not only disrupts the order of the transportation market and triggers vicious competition, but also reduces the service life of roads, causing economic losses of up to 30 billion yuan each year.

[0003] There are many problems with the traffic overload control model, including large construction scale, high law enforcement cost, single means of crackdown, long detection time, and low detection efficiency. The technological overload control non-site law enforcement system can effectively make up for the shortcomings of the traditional overload control model, improve the control scope of overweight and overloaded vehicles, and achieve precise crackdown on illegal overweight and overloaded vehicles. It uses modern scientific and technological means to conduct all-weather automatic monitoring of overweight and overloaded behavior of freight vehicles.

[0004] For example, a non-site law enforcement device for overweight control with publication number CN117542201A involves the field of traffic management technology. The prior art monitors passing vehicles through infrared monitors and detects whether the vehicle is overweight through piezoelectric film sensors. In the case of overweight, the vehicle marking spray component sprays a hazard warning sign to the rear of the vehicle, which can automatically mark the overweight vehicle, thereby conveniently reminding other vehicles and helping road police quickly learn about overweight vehicles and facilitate vehicle interception. Secondly, in rainy weather, as more rain enters the water tank, the downward pressure component controls the telescopic rain shield component to unfold, and the telescopic rain shield component shields the piezoelectric film sensor to reduce the impact of rain on detection accuracy and maintain a good detection environment.

[0005] However, the above existing technologies still have some defects when it comes to traffic overload control:

[0006] 1. The above-mentioned prior art is fixedly installed on the road, and detects whether the vehicle is overweight through a piezoelectric film sensor. When the vehicle passes, the sensor measures the pressure of the vehicle on the ground, thereby determining whether the vehicle is overweight. Vehicles generally pass quickly on the road. When a vehicle passes the sensor quickly, it may cause a brief fluctuation in the pressure value measured by the sensor, which may affect the accuracy of the measurement. At the same time, a vehicle passing quickly may cause the sensor to be unable to accurately capture the stable pressure exerted by the vehicle on the ground, thereby affecting the accuracy of determining whether the vehicle is overweight.

[0007] 2. The above-mentioned prior art uses monitoring equipment to take photos and record overloaded vehicles to provide evidence of vehicle violations. However, in actual applications, due to various reasons, the license plates of some vehicles may be contaminated by mud, dust, rain or other substances, resulting in the camera being unable to accurately identify the license plates, and the images captured by the camera may be blurred or some information is missing, which will directly affect the accuracy of the license plate recognition system. The recognition system relies on clear images to extract the license plate number and other related information. Once the image quality decreases, the recognition rate will also decrease accordingly.

[0008] Based on this and the above-mentioned viewpoints, there is still room for improvement in the existing technology for traffic control. Summary of the invention

DETAILED DESCRIPTION

[0040] The following is combined with Figures 1 to 11 This application is described in further detail.

[0041] The embodiment of the present application discloses a non-site law enforcement device for technological overweight control, which adjusts the intensity and direction of the water flow to ensure that the water flow can effectively cover the license plate area for flushing the license plate, and recycles the water after flushing to avoid wasting water resources.

[0042] Embodiment 1:

[0043] Reference Figure 1 and Figure 2 A non-site enforcement device for overweight control by science and technology comprises a support plate 1, and support frames 2 are symmetrically arranged on both sides of the support plate 1.

[0044] The support plate 1 is arranged on the road surface, and the support frames 2 on both sides are embedded in the ground. The upper end of the support frame 2 passes through the support plate 1. A weighing device 3 is arranged in the support frame 2, and the weighing device 3 is used to detect the weight of the vehicle.

[0045] Reference Figure 3 , Figure 4 and Figure 5 As shown, specifically, the weighing device 3 includes a speed reduction belt 31 slidably arranged in the support frame 2, and a partition plate 32 is arranged in the support frame 2.

[0046] When a car passes through the road, the wheels will press on the speed bump 31, causing the speed bump 31 to shrink into the support frame 2 and compress the speed bump 31. The spring 33 provided between the partition plate 32 is compressed. The weight of the vehicle is detected by detecting the movement of the speed bump 31 and the weight of the vehicle is recorded. At the same time, the vehicle is photographed through the existing visual system to identify the type and number of axles of the vehicle to obtain the load of the vehicle. The actual load of the vehicle is compared with the detected weight to determine whether the vehicle is overloaded.

[0047] When the car passes through the road, it will reduce the speed when encountering the speed bump 31, which is beneficial to the weight detection.

[0048] The partition plate 32 is slidably connected to the support frame 2 , and an adjusting screw 34 is rotatably provided at the lower end of the partition plate 32 , and the lower end of the adjusting screw 34 passes through the bottom of the support frame 2 .

[0049] By turning the adjusting screw 34, the adjusting screw 34 will drive the partition plate 32 to move in the support frame 2 through the threaded connection with the support frame 2. The moving partition plate 32 will change the elastic force of the clamping spring 33. That is, when the adjusting screw 34 drives the partition plate 32 to move upward, the clamping spring 33 is compressed, and the force of the speed reducer 31 pushing upward is greater. Conversely, when the adjusting screw 34 drives the partition plate 32 to move downward, the clamping spring 33 is released, and the force of the speed reducer 31 pushing upward is smaller.

[0050] By changing the elastic force of the pressing spring 33, the downward force of the speed reduction belt 31 is changed to adapt to vehicles of different weights.

[0051] The speed bump 31 includes a plurality of hollow speed bumps 35 , which are slidably connected to each other to form the speed bump 31 , and inclined surfaces 36 are symmetrically arranged on both sides of the speed bumps 35 .

[0052] When a car passes through the road, the wheels on both sides of the vehicle will press on the two speed bumps 35. The inclined surface 36 will guide the wheels to press on the speed bumps 35 smoothly, reducing the impact on the vehicle and ensuring that the wheels are evenly pressed on the speed bump 31. At the same time, it will be avoided that when the speed bump 31 is pressed down as a whole, other vehicles will pass through the speed bump 31 and evade weight measurement. In combination with vehicle identification technology, such as the license plate recognition system, the passage of each vehicle is tracked. If it is found that the weight of the vehicle changes abnormally when passing through the speed bump 31, further analysis can be carried out in combination with the visual monitoring system to confirm whether there is any behavior of evading weight measurement.

[0053] When the adjusting screw 34 is rotated, the adjusting screw 34 will drive the partition plate 32 to move in the support frame 2 through the threaded connection with the support frame 2. The moving partition plate 32 will change the elastic force of the clamping spring 33, and the clamping spring 33 is located between the deceleration pier 35 and the partition plate 32, so that the elastic force of multiple clamping springs 33 changes synchronously, ensuring that the downward pressure of all the deceleration piers 35 remains consistent.

[0054] Embodiment 2:

[0055] Reference Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, based on the first embodiment, in the non-site enforcement of technology-based overweight control, license plate recognition technology is one of the key means of tracking vehicles. However, in actual applications, due to various reasons, the license plates of some vehicles may be contaminated by mud, dust, rain or other substances, resulting in the camera being unable to accurately recognize the license plates, which may cause certain difficulties in law enforcement.

[0056] When the license plate is contaminated and obscured, the image captured by the camera may be blurred or some information may be missing, which will directly affect the accuracy of the license plate recognition system. The recognition system relies on clear images to extract the license plate number and other relevant information. Once the image quality decreases, the recognition rate will also decrease accordingly.

[0057] In addition, an obscured license plate may lead to misidentification or unrecognition, which not only affects the tracking and law enforcement efficiency of overloaded vehicles, but may also cause unnecessary interference to other legally traveling vehicles. In some cases, law enforcement agencies may need to rely on other means, such as vehicle feature recognition or manual intervention, to confirm the identity of the vehicle, which undoubtedly increases the complexity and workload of law enforcement.

[0058] Therefore, a flusher 4 is provided in the hollow structure of the speed reducer 35. The flusher 4 adjusts the intensity and direction of the water flow to ensure that the water flow can effectively cover the license plate area for flushing the license plate, and recycles the flushing water to avoid wasting water resources.

[0059] Specifically, the flusher 4 includes a water storage chamber 41 formed between the lower end of the partition plate 32 and the support frame 2, a water pressure plate 411 is slidably arranged in the water storage chamber 41, a return spring 42 is arranged between the lower end of the water pressure plate 411 and the support frame 2, and a connecting rod 43 that slides through the partition plate 32 is symmetrically arranged at the lower end of the deceleration pier 35.

[0060] When the car passes through the road, the wheels on both sides of the vehicle will press on the two speed reduction piers 35. The downward movement of the speed reduction piers 35 will drive the connecting rod 43. Since the lower end of the connecting rod 43 contacts the water pressure plate 411, the connecting rod 43 will push the water pressure plate 411 downward and compress the return spring 42, so that the water pressure plate 411 squeezes the water in the water storage chamber 41, and the squeezed water will enter the connecting pipe 441 set at the bottom of the support frame 2, and the connecting pipe 441 corresponds to the connecting rod 43 one by one.

[0061] Among them, a water inlet hole 431 is opened in the connecting rod 43, and the connecting pipe 441 is connected to the water storage chamber 41. The connecting pipe 441 on one side passes through the support frame 2 on the other side and then slides through the water pressure plate 411. The connecting pipe 441 slides through one end of the water pressure plate 411 and is slidably connected to the water inlet hole 431; the water squeezed on one side will pass through the connecting pipe 441 and then enter the corresponding water inlet hole 431 on the other side.

[0062] A rotating support rod 45 is rotatably arranged in the deceleration pier 35 . A hollow cavity 451 is provided in the rotating support rod 45 . An annular cover 46 is rotatably arranged on the rotating support rod 45 . A rotating hole 452 is provided on the rotating support rod 45 . A rotating disk 481 is rotatably arranged in the rotating hole 452 .

[0063] The water entering the water inlet hole 431 will flow into the connecting pipe 47 provided on the annular cover 46 along the water inlet hole 431. The connecting pipe 47 inputs the water flow into the annular cover 46 through the connection with the water inlet hole 431. The rotating support rod 45 is provided with a connecting hole 461 located in the annular cover 46. The water in the annular cover 46 will pass through the connecting hole 461 and enter the cavity 451.

[0064] Windows 49 corresponding to the rotating holes 452 are provided on the inclined surfaces 36 on the opposite sides of the speed reduction piers 35 on both sides. Since the turntable 481 has a hollow structure and is connected to the cavity 451, the water in the cavity 451 will enter the turntable 481 and then be sprayed out from the nozzle 5 provided on the turntable 481. The sprayed water will form a water column passing through the window 49 to clean the license plate, and the nozzle 5 corresponds to the window 49 one by one.

[0065] Since the speed bumps 31 are symmetrically arranged, the speed bumps 31 on one side will be pressed down by the wheels first. At this time, the connecting rod 43 on one side will push the water pressure plate 411 to move downward and compress the reset spring 42, so that the water pressure plate 411 squeezes the water in the water storage chamber 41, and the squeezed water will pass through the connecting pipe 441 into the water inlet hole 431 corresponding to the connecting rod 43 on the other side, and then be input into the annular cover 46 through the connecting pipe 441, and the water in the annular cover 46 will pass through the connecting hole 461 and enter the cavity 451.

[0066] Then, the water flows into the turntable 481 and is sprayed out from the nozzle 5 to wash the front license plate of the vehicle. After the vehicle has completely passed the speed reduction pier 35 that was pressed down first, the vehicle is located between the two speed reduction bumps 31. Then, the vehicle continues to move forward, and the speed reduction bump 31 on the other side is pressed down by the wheels at the back. At this time, the connecting rod 43 on the other side will push the water pressure plate 411 to move downward, so that the water pressure plate 411 squeezes the water in the water storage chamber 41. The squeezed water will pass through the connecting pipe 441 and enter the water inlet hole 431 of the corresponding connecting rod 43 on one side, and then be input into the annular cover 46 through the connecting pipe 441. The water in the annular cover 46 will pass through the connecting hole 461 and enter the cavity 451. Then, the water flows into the turntable 481 and is sprayed out from the nozzle 5 to wash the rear license plate of the vehicle.

[0067] The rotating disk 481 is provided with a driving gear 6 , and the rotating support rod 45 is provided with a driving rack 7 meshing with a plurality of driving gears 6 through a bracket.

[0068] By driving the driving rack 7 to move, the driving rack 7 will drive the turntable 481 to rotate through the engagement with the driving gear 6, thereby adjusting the angle of the nozzle 5 so that it is aimed at the license plate for washing. By driving the rotating support rod 45 to drive the turntable 481 to change the elevation angle of the nozzle 5, washing of license plates of different types of vehicles can be achieved.

[0069] The annular cover 46 is rotatably connected to the rotating support rod 45 , which does not affect the communication hole 461 from conveying water into the cavity 451 .

[0070] Reference Fig.11 As shown, a water storage frame 8 located between two speed bumps 31 is provided at the lower end of the support plate 1 , and a water supply pipe 81 communicating with the water storage chamber 41 is provided at the bottom of the water storage frame 8 .

[0071] The water sprayed from the nozzle 5 will fall between the two speed bumps 31, and then pass through the reflux hole 83 (at Figure 1 ) enters the water storage frame 8.

[0072] When the water pressure plate 411 moves downward, the return spring 42 will be compressed. After the vehicle passes, the compressed return spring 42 will push the water pressure plate 411 to move upward, forming a vacuum in the water storage chamber 41. At this time, the water recovered in the water storage frame 8 will pass through the water supply pipe 81 and enter the water storage chamber 41.

[0073] The one-way valve 82 disposed on the water supply pipe 81 can prevent the water in the water storage chamber 41 from entering the water storage frame 8 , so as to ensure that the water in the water storage chamber 41 can smoothly enter the connecting pipe 441 .

[0074] The implementation principle of the present invention is:

[0075] (1): When a car passes through the road, the wheels will press on the speed bump 31, causing the speed bump 31 to shrink into the support frame 2 and compress the spring 33. The weight of the vehicle is detected by detecting the travel of the speed bump 31 and the weight of the vehicle is recorded.

[0076] (2): At the same time, the existing visual system is used to take a photo of the vehicle, identify the type of vehicle and the number of axles, etc. to obtain the vehicle's load. The actual load of the vehicle is compared with the detected weight to determine whether the vehicle is overloaded.

[0077] (3): When a car passes through the road, it will reduce the speed when encountering the speed bump 31, which is beneficial to the weight detection.

[0078] (4): The adjusting screw 34 will drive the partition plate 32 to move in the support frame 2 through the threaded connection with the support frame 2. The moving partition plate 32 will change the elastic force of the clamping spring 33. By changing the elastic force of the clamping spring 33, the downward pressure of the speed bump 31 is changed to adapt to vehicles of different weights.

[0079] (5): When a car passes through the road, the wheels on both sides of the vehicle will press on the two speed bumps 35. The inclined surface 36 will guide the wheels to press on the speed bumps 35 smoothly, reducing the impact on the vehicle and ensuring that the wheels are evenly pressed on the speed bump 31. At the same time, it will prevent other vehicles from passing through the speed bump 31 and escaping weight measurement when the speed bump 31 is pressed down as a whole.

[0080] (6): The wheels on both sides of the vehicle will press on the two speed reduction piers 35. The downward movement of the speed reduction piers 35 will drive the connecting rod 43. Since the lower end of the connecting rod 43 contacts the water pressure plate 411, the connecting rod 43 will push the water pressure plate 411 downward and compress the return spring 42, so that the water pressure plate 411 squeezes the water in the water storage chamber 41, and the squeezed water will enter the connecting pipe 441 set at the bottom of the support frame 2.

[0081] (7): The water entering the water inlet hole 431 will flow into the connecting pipe 47 provided on the annular cover 46 along the water inlet hole 431. The connecting pipe 47 inputs the water flow into the annular cover 46 through the connection with the water inlet hole 431. The rotating support rod 45 is provided with a connecting hole 461 located in the annular cover 46. The water in the annular cover 46 will pass through the connecting hole 461 and enter the cavity 451.

[0082] (8): At this time, the connecting rod 43 on one side will push the water pressure plate 411 downward and compress the reset spring 42, so that the water pressure plate 411 squeezes the water in the water storage chamber 41, and the squeezed water passes through the connecting pipe 441 into the water inlet hole 431 corresponding to the connecting rod 43 on the other side, and then is input into the annular cover 46 through the connecting pipe 441. The water in the annular cover 46 passes through the connecting hole 461 and enters the cavity 451. Then, the water flows into the turntable 481 and is sprayed out from the nozzle 5 to wash the front license plate of the vehicle.

[0083] (9): After that, the vehicle continues to move forward, and the speed bump 31 on the other side is pressed down by the wheels. At this time, the connecting rod 43 on the other side will push the water pressure plate 411 to move downward, so that the water pressure plate 411 squeezes the water in the water storage chamber 41. The squeezed water will pass through the connecting pipe 441 and enter the water inlet hole 431 of the corresponding connecting rod 43 on one side, and then be input into the annular cover 46 through the connecting pipe 441. The water in the annular cover 46 will pass through the connecting hole 461 and enter the cavity 451. Then, the water flow will enter the turntable 481 and be sprayed out from the nozzle 5 to wash the rear license plate of the vehicle.

[0084] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
