Abstract
Description
Technical Field
[0001] This invention relates to an automatic recording device and application method for high beam violation in the field of traffic management equipment technology. Background Technology
[0002] Nighttime driving poses significantly higher safety risks than daytime driving, with drivers' improper use of high beams when meeting oncoming traffic being a major contributing factor to nighttime road accidents. Although national regulations clearly require drivers to switch to low beams at least 150 meters away from oncoming vehicles at night, a considerable proportion of drivers still violate this rule in practice. The intense glare of high beams can cause momentary dazzle and temporary blindness to oncoming drivers, leading to loss of control, rear-end collisions, and other accidents. Traditional high beam violation detection and recording devices are typically mounted on road monitoring support frames, with fixed locations that can only detect and record violations within a specific section of the road, resulting in a limited monitoring scope.
[0003] The invention patent with publication number CN102381250B discloses a monitoring device for vehicles illegally using high beams when meeting oncoming traffic at night. It includes a front-mounted acquisition unit located below the driver's cab, in the area between the left and right headlights; and a driver's cab control unit located inside the driver's cab and connected to the front-mounted acquisition unit. The front-mounted acquisition unit further includes: a camera; a high-position LED light source; a low-position LED light source; lenses positioned in front of the high-position and low-position LED light sources, respectively, with parallel light emission; and a first control unit, used to control the high-position or low-position LED light source to emit light according to the high-position or low-position light control command issued by the driver's cab control unit, and to activate the camera, sending the license plate image information transmitted by the camera to the driver's cab control unit for storage. This completes the evidence collection for vehicles illegally using high beams when meeting oncoming traffic at night, achieving the purpose of restraining drivers from using high beams according to regulations when meeting oncoming traffic at night. While this patent can photograph and record vehicles illegally using high beams when meeting oncoming traffic, it cannot record following vehicles or the vehicle itself violating high beam regulations, thus limiting the types of violations it can identify. Furthermore, the monitoring device only connects to the front of the vehicle, making it susceptible to scrapes and collisions, which could damage the equipment and increase operating costs. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned technical defects and provide an automatic recording device and application method for high beam violations.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic recording device and application method for high beam violations, comprising a main control processing module and a front-end core detection module, a rear-end auxiliary detection module, a vehicle high beam status acquisition module, a vehicle interaction module, a warning module, and a power management module that interact with the main control processing module via a high-speed bus; the main control processing module adopts an embedded ARM Cortex-A76 processor, with a built-in dedicated multi-dimensional violation detection algorithm, which can process the data collected by each module and complete scene judgment and violation identification, while realizing local storage and real-time uploading of violation data; the front-end core detection module and the rear-end auxiliary detection module are respectively installed at the top center of the vehicle's windshield and rear windshield, respectively, both using dual cameras. The dual cameras work together to capture image information of oncoming and rear vehicles, and use binocular vision technology to determine the distance between the vehicle and the vehicle, providing conditions for judging high beam violations. The high-definition night vision camera and infrared camera in the front-end core detection module are also used to capture road signs and judge the road environment. The front-end core detection module also includes an ambient light sensor. The system is used to detect ambient light, providing basic data for judging high beam violations. The vehicle's high beam status acquisition module uses a non-invasive current sensor, clipped into the vehicle's high beam control circuit. It can accurately identify the "on" and "off" status of the vehicle's high beams by detecting current changes in the high beam control circuit and transmits the status data to the main control processing module in real time. The vehicle interaction module connects the main control processing module and the vehicle's ECU, used to send equipment fault warning signals to the vehicle's instrument panel. The warning prompt module includes a voice prompt module and a light alarm module, used to indicate the road environment ahead and to issue an alarm reminder when the vehicle is using high beams illegally. The power management module has overvoltage, overcurrent, and short-circuit protection functions, as well as a delayed power-off function after the vehicle is turned off. The infrared camera has an effective detection range of 50-200m.
[0006] Furthermore, the ambient light sensor employs a high-precision photoresistor with a detection range of 0.1-10000 lux, and collects ambient light intensity data 10 times per second.
[0007] Furthermore, the dual cameras include a high-definition night vision camera and an infrared camera. The high-definition night vision camera relies on visible light imaging, providing true colors and clear details. As the main camera, it is used to identify road signs, capture the appearance features and license plate information of oncoming vehicles / vehicles in front, and provide key image data for "road type determination" and "illegal vehicle identification record". The infrared camera relies on infrared light imaging, is not limited by lighting conditions, and can work normally in low-light / no-light environments such as night, dawn and dusk, and tunnels, thus compensating for the imaging shortcomings of the high-definition night vision camera in dark environments.
[0008] Furthermore, both the front-end core detection module and the rear-end auxiliary detection module are equipped with angle-adjustable brackets to adjust the camera angle and ensure maximum field of view. The adjustable brackets include a device housing, a first support arm, a second support arm, and a fixing plate. One end of the first support arm is fixedly connected to the device housing, and the other end is provided with a hinge seat with a hinge hole. One end of the second support arm is fixedly connected to the fixing plate, and the other end is a hinge end with a shaft hole. A hinge shaft is installed inside the hinge shaft, which has a polygonal structure in the middle and slides with the shaft hole. One end of the hinge shaft is fixedly connected to a first handle, and the other end is threadedly connected to a second handle. The side wall of the hinge seat is provided with a groove, and a retaining spring is installed inside. The two ends of the retaining spring abut against the second handle and the inner wall of the groove, respectively.
[0009] Furthermore, the main control processing module is installed in the passenger-side storage compartment of the vehicle, with a reserved USB 3.0 interface and SD card slot for data storage and device debugging; the SD card supports cyclic overwrite storage, can retain the most recent 1000 violation records, and is equipped with a 4G communication module, which is used to upload violation data to the vehicle owner's mobile APP and connect to the traffic management platform; the violation data includes the violation time, the license plate of the violating vehicle, the violation scene, and on-site images.
[0010] Furthermore, the power management module is powered via the vehicle's cigarette lighter interface or directly connected to the vehicle battery, and is installed in the vehicle's engine compartment with a waterproof design; the power management module has a delayed power-off function, which delays powering off the device by 10 seconds after the vehicle has been parked for a short period of time to ensure that data is saved completely.
[0011] An application method for an automatic recording device for high beam violations. S1: Start-up and initialization. After the vehicle starts, the power management module is powered on, the main control processing module completes initialization and performs a self-test on all modules. If a fault occurs, the fault warning is displayed on the vehicle instrument panel or central control screen through the vehicle communication module. If it is normal, it enters the formal testing state. S2: Scene Determination: The ambient light sensor detects the ambient light to determine whether it is a nighttime, dawn / dusk / tunnel scene. If so, the front core detection module, the rear auxiliary detection module, and the vehicle's high beam status acquisition module are activated. At the same time, the high-definition night vision camera of the front core detection module captures road signs to determine the road type scene. S3: Violation Detection. The front core detection module, rear auxiliary detection module, and vehicle high beam status acquisition module simultaneously collect images of vehicles driving in front and behind, as well as data on the vehicle's high beam status. After marking the data with timestamps, the data is transmitted to the main control processing module. The main control processing module uses a multi-dimensional violation detection algorithm to process and identify the images collected by the front core detection module and the rear auxiliary detection module. For oncoming vehicles and following vehicles, it combines the high beam usage rules for different scenarios with the light status captured by the camera to determine the violation. The light status is identified through image grayscale values, light outlines, and illumination direction. The vehicle high beam status acquisition module accurately identifies the "on" and "off" status of the vehicle's high beams by detecting changes in the current of the high beam control circuit and transmits this information to the main control processing module. S4: Tiered warning and data upload. If the vehicle violates the high beam rule, the driver will be alerted by the voice prompt module and the light alarm module to use the lights correctly. If the lights are not changed after the prompt, the violation will be recorded and uploaded to the vehicle management system via the 4G module. At the same time, the main control processing module will record the violations of vehicles in front and behind and upload them to the vehicle management system via the 4G module. S5: Stop and data preservation. After the vehicle is turned off, the power management module delays power-off. After the main control processing module completes the re-upload of unuploaded data and local data organization and saving, the device enters sleep mode.
[0012] Furthermore, in step S2, light intensity <10 lux represents a nighttime scene, 10-500 lux represents a dawn / dusk / tunnel scene, and >500 lux represents a daytime scene; road scenes are divided into urban roads, highways, and suburban roads.
[0013] Furthermore, in step S3, the violations related to high beams and the specific identification methods are as follows: S31. Violation of oncoming vehicle high beam violation: In nighttime / dawn / tunnel scenarios, when an oncoming vehicle approaches within 150 meters of the vehicle, the high beams are on and not turned off. Specific identification method: An ambient light sensor monitors the ambient light to determine the nighttime / dawn / tunnel scenario. The front-mounted core detection module uses "binocular vision ranging technology," with a fixed distance between the two cameras. By capturing the pixel offset of the oncoming vehicle (or its light area) in the images of the two cameras, combined with preset parameters such as camera focal length and baseline distance, the real-time distance between the oncoming vehicle and the vehicle is calculated using triangulation principles. Simultaneously, image size change rate calibration is used (as the oncoming vehicle approaches, its size gradually increases in the image; the size change rate is calculated by comparing consecutive frames to correct the distance data), ensuring that the distance judgment error is ≤5m. When the calculated distance is <150m and the oncoming vehicle has its high beams on, it is determined to be a violation of oncoming vehicle high beam violation. S32. Violation of high beam violation by following vehicle: In night / dawn / tunnel scenarios, if a following vehicle turns on its high beam when the distance between the following vehicle and the vehicle is less than 100m; Specific identification method: The ambient light sensor monitors the ambient light to determine the night / dawn / tunnel scenario, and the "binocular vision ranging technology" of the rear auxiliary detection module determines that the distance between the following vehicle and the vehicle is less than 100m and the following vehicle has turned on its high beam, which is then judged as a violation of high beam violation by the following vehicle; S33. When high beams are turned on on urban roads, if the road sign identified by the front core detection module is an urban road, and the front core detection module and the rear auxiliary detection module detect that oncoming vehicles or following vehicles have their high beams on, it is determined to be a violation of high beams on urban roads. S34. Vehicle's high beam violation: When the road sign identified by the front core detection module is an urban road, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to an oncoming vehicle is less than 150m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to the vehicle in front is less than 100m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation. When the vehicle's high beams are in violation, the voice prompt module and the light alarm module will issue a warning.
[0014] Furthermore, the illegal data mentioned in step S4 is transmitted using AES-256 encryption; if the 4G signal is interrupted, the data is temporarily stored locally and will automatically continue to be uploaded after the signal is restored.
[0015] The beneficial effects of this invention: This invention breaks through the shortcomings of traditional high beam violation recording devices, which have fixed positions and limited detection ranges. By installing the violation recording device on the vehicle, it can more comprehensively detect violations such as high beam violations when meeting oncoming traffic, high beam violations by following vehicles, and high beam violations on urban roads, filling the detection blind spots of traditional devices.
[0016] The front-end core detection module and the rear-end auxiliary detection module of this invention are both located inside the vehicle, thereby avoiding damage to the detection device caused by vehicle friction or collision, and improving the safety and service life of the equipment.
[0017] The front-end core detection module and the rear-end auxiliary detection module of this invention both employ dual cameras, with a high-definition night vision camera as the primary camera and an infrared camera as the auxiliary camera. This compensates for the imaging shortcomings of the high-definition night vision camera in low-light environments. The two cameras work together to ensure accurate and comprehensive image acquisition, thereby improving recognition accuracy and avoiding misjudgments. At the same time, the dual cameras are equipped with binocular vision ranging technology, which quickly and accurately calculates the vehicle distance through pixel offset and triangulation principles, thus providing data support for the determination of high beam violations.
[0018] When this vehicle violates the high beam rule, a reminder will be given first. If the driver does not switch the lights after being reminded, the information will be uploaded to the vehicle management system, which will record and report the violation of other vehicles and impose restrictions on this vehicle. This effectively improves the driver's compliance awareness, guides the standardized use of lights, and creates a safe driving environment.
[0019] The main control processing module uses an embedded ARM Cortex-A76 processor and has a built-in dedicated multi-dimensional violation detection algorithm. It can efficiently process multi-source data collected by various modules, quickly complete scene judgment and violation identification, and avoid missed identification. The main control processing module is equipped with dual data channels: local storage on an SD card and remote upload via 4G. The SD card supports cyclic overwriting of 1000 violation records, and the 4G module enables real-time upload of violation data to the vehicle owner's APP and traffic management platform. The data is transmitted using AES-256 encryption and has a function for offline caching and retransmission to prevent data loss or tampering. The violation data includes full-element information such as time, license plate, scene, and on-site images, which can be directly used as evidence for law enforcement, improving the standardization and efficiency of traffic law enforcement.

[0024] The ambient light sensor uses a high-precision photoresistor with a detection range of 0.1-10000 lux, and collects ambient light intensity data 10 times per second.
[0025] The dual cameras include a high-definition night vision camera and an infrared camera.

[0026] As shown in 4-5, both the front core detection module and the rear auxiliary detection module are equipped with angle-adjustable brackets to adjust the camera angle and ensure maximum field of view. The adjustable bracket includes a device housing 1, a first support arm 2, a second support arm 3, and a fixing plate 4. One end of the first support arm 2 is fixedly connected to the device housing 1, and the other end is provided with a hinge seat 5, which has a hinge hole 6. One end of the second support arm 3 is fixedly connected to the fixing plate 4, and the other end is a hinge end with a shaft hole 7. A hinge shaft 8 is installed inside. The middle part of the hinge shaft 8 has a polygonal structure and slides with the shaft hole 7.

The side wall of the hinge seat 5 is provided with a groove 11, and a retaining spring 12 is installed inside. The two ends of the retaining spring 12 abut against the second handle 10 and the inner wall of the groove 11, respectively.
[0027] The main control processing module is installed in the passenger-side storage compartment of the vehicle, with a reserved USB 3.0 interface and SD card slot for data storage and device debugging. The SD card supports cyclic overwrite storage, can retain the most recent 1000 violation records, and is equipped with a 4G communication module. The 4G module is used to upload violation data to the vehicle owner's mobile APP and connect to the traffic management platform.

[0028] The power management module is powered via the vehicle's cigarette lighter interface or by direct connection to the vehicle battery. It is installed in the vehicle's engine compartment and features a waterproof design. The power management module has a delayed power-off function, which disconnects the device 10 seconds after the vehicle has been parked for a short period of time to ensure that data is saved completely.
[0029] like Figure 2-3 As shown, an application method for an automatic recording device for high beam violations includes the following steps: S1: Start-up and initialization. After the vehicle starts, the power management module is powered on, the main control processing module completes initialization and performs a self-test on all modules. If a fault occurs, the fault warning is displayed on the vehicle instrument panel or central control screen through the vehicle communication module. If it is normal, it enters the formal testing state. S2: Scene Determination: The ambient light sensor detects the ambient light to determine whether it is a nighttime, dawn / dusk / tunnel scene. If so, the front core detection module, rear auxiliary detection module, and vehicle high beam status acquisition module are activated. Light intensity <10 lux indicates a nighttime scene, 10-500 lux indicates a dawn / dusk / tunnel scene, and >500 lux indicates a daytime scene. At the same time, the high-definition night vision camera of the front core detection module captures road signs to determine the road type scene, including urban roads, highways, and suburban roads. S3: Violation Detection. The front core detection module, rear auxiliary detection module, and vehicle high beam status acquisition module simultaneously collect images of vehicles driving in front and behind, as well as data on the vehicle's high beam status. After marking the data with timestamps, the data is transmitted to the main control processing module. The main control processing module uses a multi-dimensional violation detection algorithm to process and identify the images collected by the front core detection module and the rear auxiliary detection module. For oncoming vehicles and following vehicles, it combines the high beam usage rules for different scenarios with the light status captured by the camera to determine the violation. The light status is identified through image grayscale values, light outlines, and illumination direction. The vehicle high beam status acquisition module accurately identifies the "on" and "off" status of the vehicle's high beams by detecting changes in the current of the high beam control circuit and transmits this information to the main control processing module. S4: Tiered warning and data upload. If the vehicle violates the high beam rule, the driver will be alerted via voice prompts and a light alarm module to use the lights correctly. If the driver fails to change the lights after being alerted, the violation will be recorded and uploaded to the vehicle management system via the 4G module. At the same time, the main control processing module will record the violations of vehicles in front and behind and upload them to the vehicle management system via the 4G module. The violation data is transmitted using AES-256 encryption. If the 4G signal is interrupted, the data will be temporarily stored locally and will be automatically uploaded again after the signal is restored. S5: Stop and data preservation. After the vehicle is turned off, the power management module delays power-off. After the main control processing module completes the re-upload of unuploaded data and local data organization and saving, the device enters sleep mode.
[0030] Step S3: Violations of high beam regulations and specific identification methods: S31. Violation of oncoming vehicle high beam violation: In nighttime / dawn / tunnel scenarios, when an oncoming vehicle approaches within 150 meters of the vehicle, the high beams are on and not turned off. Specific identification method: An ambient light sensor monitors the ambient light to determine the nighttime / dawn / tunnel scenario. The front-mounted core detection module uses "binocular vision ranging technology," with a fixed distance between the two cameras. By capturing the pixel offset of the oncoming vehicle (or its light area) in the images of the two cameras, combined with preset parameters such as camera focal length and baseline distance, the real-time distance between the oncoming vehicle and the vehicle is calculated using triangulation principles. Simultaneously, image size change rate calibration is used (as the oncoming vehicle approaches, its size gradually increases in the image; the size change rate is calculated by comparing consecutive frames to correct the distance data), ensuring that the distance judgment error is ≤5m. When the calculated distance is <150m and the oncoming vehicle has its high beams on, it is determined to be a violation of oncoming vehicle high beam violation. S32. Violation of high beam violation by following vehicle: In night / dawn / tunnel scenarios, if a following vehicle turns on its high beam when the distance between the following vehicle and the vehicle is less than 100m; Specific identification method: The ambient light sensor monitors the ambient light to determine the night / dawn / tunnel scenario, and the "binocular vision ranging technology" of the rear auxiliary detection module determines that the distance between the following vehicle and the vehicle is less than 100m and the following vehicle has turned on its high beam, which is then judged as a violation of high beam violation by the following vehicle; S33. When high beams are turned on on urban roads, if the road sign identified by the front core detection module is an urban road, and the front core detection module and the rear auxiliary detection module detect that oncoming vehicles or following vehicles have their high beams on, it is determined to be a violation of high beams on urban roads. S34. Vehicle's high beam violation: When the road sign identified by the front core detection module is an urban road, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to an oncoming vehicle is less than 150m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to the vehicle in front is less than 100m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation. When the vehicle's high beams are in violation, the voice prompt module and the light alarm module will issue a warning.

The power management module has a delayed power-off function, which disconnects the device 10 seconds after the vehicle has been parked for a short period of time to ensure that data is saved completely.
7. An application method for an automatic recording device for high beam violations, characterized in that, Includes the following steps: S1: Start-up and initialization. After the vehicle starts, the power management module is powered on, the main control processing module completes initialization and performs a self-test on all modules. If a fault occurs, the fault warning is displayed on the vehicle instrument panel or central control screen through the vehicle communication module. If it is normal, it enters the formal testing state. S2: Scene Determination: The ambient light sensor detects the ambient light to determine whether it is a nighttime, dawn / dusk / tunnel scene. If so, the front core detection module, the rear auxiliary detection module, and the vehicle's high beam status acquisition module are activated. At the same time, the high-definition night vision camera of the front core detection module captures road signs to determine the road type scene. S3: Violation Detection. The front core detection module, rear auxiliary detection module, and vehicle high beam status acquisition module simultaneously collect images of vehicles driving in front and behind, as well as data on the vehicle's high beam status. After marking the data with timestamps, the data is transmitted to the main control processing module. The main control processing module uses a multi-dimensional violation detection algorithm to process and identify the images collected by the front core detection module and the rear auxiliary detection module. For oncoming vehicles and following vehicles, it combines the high beam usage rules for different scenarios with the light status captured by the camera to determine the violation. The light status is identified through image grayscale values, light outlines, and illumination direction. The vehicle high beam status acquisition module accurately identifies the "on" and "off" status of the vehicle's high beams by detecting changes in the current of the high beam control circuit and transmits this information to the main control processing module. S4: Tiered warning and data upload. If the vehicle violates the high beam rule, the driver will be alerted by the voice prompt module and the light alarm module to use the lights correctly. If the lights are not changed after the prompt, the violation will be recorded and uploaded to the vehicle management system via the 4G module. At the same time, the main control processing module will record the violations of vehicles in front and behind and upload them to the vehicle management system via the 4G module. S5: Stop and data preservation. After the vehicle is turned off, the power management module delays power-off. After the main control processing module completes the re-upload of unuploaded data and local data organization and saving, the device enters sleep mode.
8. The application method of the automatic recording device for high beam violations according to claim 7, characterized in that, In step S2, light intensity <10 lux represents a nighttime scene, 10-500 lux represents a dawn / dusk / tunnel scene, and >500 lux represents a daytime scene; road scenes are divided into urban roads, highways, and suburban roads.
9. The application method of the automatic recording device for high beam violations according to claim 7, characterized in that, Step S3: Violations of high beam regulations and specific identification methods: S31. Violation of oncoming vehicle high beam violation: In nighttime / dawn / tunnel scenarios, when an oncoming vehicle approaches within 150 meters of the vehicle, the high beams are on and not turned off. Specific identification method: An ambient light sensor monitors the ambient light to determine the nighttime / dawn / tunnel scenario. The front-mounted core detection module uses "binocular vision ranging technology," with a fixed distance between the two cameras. By capturing the pixel offset of the oncoming vehicle in the images from the left and right cameras, combined with preset parameters such as camera focal length and baseline distance, the real-time distance between the oncoming vehicle and the vehicle is calculated using triangulation principles. Simultaneously, image size change rate calibration is used to ensure that the distance judgment error is ≤5m. When the calculated distance is <150m and the oncoming vehicle has its high beams on, it is determined to be a violation of oncoming vehicle high beam violation. S32. Violation of high beam violation by following vehicle: In night / dawn / tunnel scenarios, if a following vehicle turns on its high beam when the distance between the following vehicle and the vehicle is less than 100m; Specific identification method: The ambient light sensor monitors the ambient light to determine the night / dawn / tunnel scenario, and the "binocular vision ranging technology" of the rear auxiliary detection module determines that the distance between the following vehicle and the vehicle is less than 100m and the following vehicle turns on its high beam, which is then judged as a violation of high beam violation by the following vehicle; S33. When high beams are turned on on urban roads, if the road sign identified by the front core detection module is an urban road, and the front core detection module and the rear auxiliary detection module detect that oncoming vehicles or following vehicles have their high beams on, it is determined to be a violation of high beams on urban roads. S34. Vehicle's high beam violation: When the road sign identified by the front core detection module is an urban road, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to an oncoming vehicle is less than 150m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation; when the front core detection module detects that the distance to the vehicle in front is less than 100m, the vehicle's high beam status acquisition module will detect that the vehicle's high beams are on and determine a violation. When the vehicle's high beams are in violation, the voice prompt module and the light alarm module will issue a warning.
10. The application method of the automatic recording device for high beam violations according to claim 7, characterized in that, The illegal data mentioned in step S4 is transmitted using AES-256 encryption; if the 4G signal is interrupted, the data is temporarily stored locally and will be automatically uploaded again after the signal is restored.
