[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0024] like Figure 1-2 As shown, a nighttime vehicle high beam control system is set up based on a highway isolation belt, and the high beam control system is installed based on the central isolation belt of an ordinary highway. The high beam control system includes a box 6, a shading grating 3 and a photosensitive element 4. The box 6 is set on the highway isolation belt, and the box 6 is at a certain height from the road surface. The specific height is based on the eye height of the driver of a conventional family car in the driving state, so as to detect whether it is a high beam from the perspective of the oncoming vehicle; the end of the box 6 corresponding to the driving direction of the vehicle is the light input end, and a plurality of shading gratings 3 are arranged inside the box 6, and the plurality of shading gratings 3 are evenly distributed in the longitudinal direction and are relatively close to each other. There is a light-transmitting slit between two adjacent shading gratings 3; the end of the box 6 facing the light-incoming end is the light-sensing end, and a plurality of light-sensing elements 4 corresponding to the light-transmitting slits are provided on the inner wall of the light-sensing end; the shading grating 3 blocks the diffracted light at other angles, and only selects the light parallel to the light-transmitting slits to be projected onto the light-sensing element 4. Since the height of the box 6 is adapted to the height of the driver's eyes, when the vehicle starts to use the high beam, the light is parallel to the shading grating 3, and more light will be projected onto the light-sensing element 4. The light-sensing element 4 is correspondingly connected to a controller to determine whether the light of the approaching vehicle is the high beam according to the monitoring signal of the light-sensing element 4. The light-sensing element 4 is correspondingly connected to the controller, and can transmit the detected light-sensing signal to the controller, and the light-sensing intensity is preset by the controller. When the light-sensing element 4 detects that the light intensity is high or reaches a certain standard, the controller determines that the light of the approaching vehicle is the high beam.

[0025] In this embodiment, the photosensitive element 4 is a photoresistor, and the controller is a programmable logic controller (PLC) or a single-chip microcomputer. This device is suitable for monitoring high beams on relatively flat roads to ensure the accuracy of light detection.

[0026] In an optional embodiment, the controller is connected to a display panel 5, which may be a liquid crystal screen or an LED display screen. When the controller determines that the lights of the oncoming vehicle are high beams based on the detection information of the photosensitive element 4, the controller controls the display panel 5 to display a warning message, and the warning message includes but is not limited to "You have violated traffic rules, please turn off the high beams", which warns the driver of the oncoming illegal vehicle and reminds the driver to turn off the high beams.

[0027] In an optional embodiment, the display panel 5 is fixedly connected to the box body 6, and the display panel 5 faces the direction of the oncoming vehicle so as to provide a text warning to the driver.

[0028] In an optional embodiment, the controller is connected to a corresponding evidence camera 1, which can take photos of high-beam vehicles when the lights of an oncoming vehicle are high beams, and the controller is communicatively connected to a traffic management system to send the evidence photos to the traffic management system. The traffic management system can remind the driver of the violation via text message or manual reminder, and use the evidence photos as punishment evidence. In this embodiment, the evidence camera 1 is a reverse camera, and its direction is consistent with the direction of vehicle travel. After the vehicle passes through the box 6, the rear license plate of the illegal vehicle is captured, so as to avoid the problem of difficulty in obtaining evidence caused by the strong light of the vehicle's high beam. The evidence camera 1 can be set on the box 6 or the light box of the LED display screen to ensure the integration of the present invention and facilitate temporary installation and use; or, the evidence camera 1 is set in front of the box 6 and keeps a certain distance from the box 6. When the vehicle enters between the evidence camera 1 and the box 6, the evidence camera 1 is turned on to capture the rear license plate of the illegal vehicle. At this time, the evidence camera 1 is relatively independent, and a wireless communication module is set on the evidence camera 1, which is connected to the controller through the wireless communication module and transmitted to the traffic management system through the controller. The traffic management system and the controller are also connected through the wireless communication module. In this embodiment, the wireless communication module can be a 5G module. Preferably, the light box of the LED display screen is fixed on the box 6, and the evidence camera 1, the speed radar and the distance radar 2 are correspondingly fixed on the light box of the LED display screen.

[0029] In an optional embodiment, the high beam management system also includes a speed radar and a ranging radar 2, which can monitor the vehicle speed through the speed radar and capture the vehicle speeding at the same time. The speed radar and the ranging radar are connected to the controller accordingly; in this embodiment, the system can detect the high beam of the oncoming vehicle within a distance range of 150 meters to 100 meters. If it is found that the oncoming vehicle has turned on the high beam, the prompt system will issue a reminder warning through the LCD panel; a ranging radar is set to give the emcee a certain opportunity to correct it. If the oncoming vehicle still does not change the lights at a distance of 0 meters to 50 meters, the evidence camera 1 will be started to collect evidence. The ranging radar can also monitor the distance between the vehicle and the system in real time to ensure that the evidence camera 1 is started through the controller at the right time and position to take pictures and collect evidence.

[0030] In an optional embodiment, the box body 6 is a square box body 6, and correspondingly, the light shielding grating 3 is a plate body adapted to the horizontal cross-section of the inner cavity of the box body 6, and there is a certain gap between the end of the light shielding grating 3 corresponding to the photosensitive element 4 and the photosensitive element 4; the box body 6 can be a metal box body 6 or a plastic box body 6, and installation grooves corresponding to the light shielding grating 3 are provided on both sides of its inner wall. The light shielding grating 3 is relatively thin and made of opaque material, and the length of the box body 6 is 50-80cm.

[0031] In an optional embodiment, a clamp 7 is correspondingly provided on the box 6, and the clamp 7 is correspondingly connected to the highway isolation belt. Through the detachable connection of the clamp 7, the system can be quickly connected to the central isolation guardrail, concrete crash barrier or corrugated beam guardrail, and temporary lighting management can be performed according to actual needs. In an embodiment, the box 6 can also be fixed to the highway isolation belt by bolts, clamps, steel wires, etc., and the specific connection form is not limited here.

[0032] In an optional embodiment, the height of the box 6 from the road surface is 1.2m-1.5m. This height, combined with the height of the box 6 itself, is just adapted to the position of the glasses of most family car drivers. The high beam is judged from the driver's perspective, which can truly protect the driving environment of oncoming drivers and improve driving safety.

[0033] In an optional embodiment, a transparent baffle is provided at the light-inlet end of the box 6 to seal the box 6. The baffle may be a highly transparent acrylic plate, which can ensure the sealing of the box 6 to the greatest extent while ensuring the penetration of light, and prevent dust and other debris from entering the box 6. The above scheme will greatly improve the efficiency of high beam management, and normalized law enforcement can also maintain the deterrent effect of the law, and promptly remind drivers and passengers to turn off the high beam to avoid interference with oncoming vehicles, avoid and reduce traffic accidents, and has good use effect and broad market prospects.

[0034] In an optional embodiment, two adjacent shading gratings 3 are coated with light-absorbing materials, and the width of the light-transmitting gap is determined by controlling the length of the shading grating 3. Specifically, it is set to allow the light of flat incident and ±5 degrees to pass through, and shield the light of other angles to ensure the accuracy of high beam monitoring. It can be understood that the above description is only exemplary, and the embodiments of the present application are not limited to this.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
