[0002] Urban industrial areas are usually far away from urban areas due to various industrial and transportation activities, so as to avoid dust and noise that may interfere with the normal lives of urban residents. On the roads in industrial areas, most of the traffic is from large transport vehicles, which are very heavy. Therefore, the road surface is frequently damaged, resulting in local depressions and sinking.

[0003] Most of the existing street lights in industrial areas are fixedly installed on the top of the lamp poles. Generally, they only focus on illuminating the middle part of the road surface, and the lighting angle and area of ​​the street lights cannot be adjusted. There are many potholes on the roads in industrial areas. Some potholes are close to the edge of the central lighting area of ​​the street lights. It is not easy for drivers to find them when passing by, so they have no time to react to avoid them or slow down in advance. They pass slowly, which easily causes driving safety problems.

[0004] Therefore, in order to address the problem that potholes on roads in urban industrial zones often do not receive key lighting from street lamps, affecting the safe driving of transport vehicles, a street lamp can be designed that can intelligently adjust the key lighting areas according to the location of potholes on the road surface to ensure safe driving of vehicles at night.

[0016] Beneficial effects of the present invention:

[0017] 1. The monocular camera installed on the street lamp captures the cross-section of the road. The information processing background calculates the location of potholes on the road according to the size and distribution of the local pixel grayscale value of the image, and controls the adjustable lighting components to make corresponding adjustments, focusing on the area where the potholes are located. This makes it easier for drivers to observe road damage at night, helping them to react in time to avoid or slow down, and ensure driving safety;

[0018] 2. The original overall lamp is designed into a three-section structure. The auxiliary lamps on both sides are preset with lighting angles according to the width of the road surface, and illuminate the parts near the shoulders respectively. The main lamp in the middle section can automatically perform key lighting according to the potholes on the road surface. When the main lamp adjusts the angle, it is fed back to the auxiliary lamps on both sides through torque sensing, and the angle is adjusted synchronously to always ensure the lighting near the shoulders on both sides, avoiding that all the lights of the street lamps are too biased to illuminate one side of the road, resulting in a significant reduction in the lighting amount of the area near the shoulder on the other side;

[0019] 3. The cleaning component can be used to clean the monocular camera to prevent the monocular camera from being contaminated by dust on industrial roads, which may affect the detection accuracy of potholes on the road.

[0020] 4. After cleaning the monocular camera, the cleaning component can also pass through the main light and the auxiliary light during the folding process and clean them to prevent the lamp from being contaminated by dust and causing insufficient lighting brightness;

[0021] 5. The steering assembly set on the lamp pole can be used to adjust the position of the cleaning assembly to avoid the lamp stand above. In conjunction with the adjustment of the photovoltaic assembly, it is convenient to clean the photovoltaic panel on the pole head and ensure the light absorption efficiency of the photovoltaic panel.

[0022] 6. The warning light set on the pole head can be activated automatically based on the monocular camera's recognition of whether there are potholes on the road section. The flashing light can remind drivers ahead at night that there are potholes on the road corresponding to the street light, which helps to warn in advance.

[0023] 5. After the cleaning component is finished, it can be stored in the storage bin on the lamp pole, making the overall appearance of the street lamp more beautiful, while avoiding exposure to large wind resistance and affecting the stability of the lamp pole;

[0024] 6. The cleaning component is repeatedly lifted and lowered during operation. The sensor radar on it can monitor the distance of obstacles (i.e., street trees) on its path. When the detected obstacle is too close to its path, it means that the camera angle of the monocular camera and the lighting angle of the street lamp are blocked, which can help managers take measures in advance (i.e., repair the tree crown);

[0025] 7. By setting a spray component on the lamp pole to supply water to the cleaning component, it can achieve spraying and wiping cleaning at the same time, improving the cleaning effect of photovoltaic panels, monocular cameras, main lights and auxiliary lights;

[0026] 8. Make full use of rainwater collected in water storage tanks, daily watering and dust reduction on industrial roads, and water collected from sprinkler trucks during watering of green belts as clean water, which is more environmentally friendly and energy-saving;

[0027] 9. A cleaning component is set on the stacking bin. After the cleaning roller is stored, the cleaning roller is cleaned with water supplied by the water storage bin to remove the dirt on the cleaning roller for the next use.

[0028] 10. The wastewater after washing the cleaning roller is discharged into the green belt below through the drainage pipe. Combined with the permeable blind pipes pre-arranged in the green belt, the plants can be evenly watered within a certain distance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

After obtaining the position of the pothole on the road surface, the angle of rotation adjustment of the main lamp 605 is calculated according to the lighting area of ​​the main lamp 605 in the initial state, and an operation instruction is issued to the adjustable lighting component to start the No. 1 motor 601. Through the meshing transmission of the driving gear 602 and the driven gear 603, the main lamp 605 rotates to the side of the pothole on the road surface until the lighting direction of the main lamp 605 is on the same axis as the pothole position (it is worth noting that the lighting area of ​​the main lamp 605 is adjusted to the middle position of the road cross section to prevent the lighting area of ​​the main lamp 605 from being too close to the edge of the road surface. For example, for a single-lane three-lane road, the lighting adjustment area of ​​the main light 605 is concentrated near the middle lane, while the lighting areas of the auxiliary light 704 are respectively concentrated on the fast lane and the adjacent curb, and the slow lane and the adjacent curb). After the main light 605 is rotated and adjusted, the auxiliary light 704 rotates along with the main light 605, resulting in an offset in the lighting near the curb. At this time, according to the torque parameter of the torsion spring 606 detected by the torque sensor 607 and a signal sent to the fixed lighting component, the second motor 703 is started, and the movable arm 702 is controlled to drive the corresponding auxiliary light 704 to rotate a certain angle again, so that the lighting area of ​​the auxiliary light 704 is adjusted to the curb again, so that the key lighting area of ​​the street light covers the curbs on both sides of the road and the potholes on the road surface.The principle of the monocular camera 8 capturing images and identifying and correcting image information is as follows: The monocular camera 8 captures the cross-sectional image of the road facing it obliquely downward, and its relative height position with the road surface is fixed, and the width of the cross-sectional width of the road surface is fixed. After obtaining the position of the pothole on the plane, the lighting adjustment angle of the main light 605 can be calculated according to the trigonometric function formula. The road image captured by the monocular camera 8 is an image with fixed horizontal and vertical dimensions, and forms a number of rows of pixel base points (parallel to the driving direction) on the cross-sectional view of the road. The pothole situation of the road surface is determined according to the size of the pixel grayscale value on each row of pixel base points, and the position of the pothole is formed in the form of a pixel row position. The signal is sent to the control unit of the adjustable lighting component, and the lighting range of the light is adjusted from the middle of the road to the road cross-sectional position where the pixel grayscale value is the largest, that is, the position of the pothole depth is the largest. For specific identification and calculation methods, please refer to the invention patent disclosed in announcement number CN111274939.A: Automatic extraction method for pothole damage on road surface based on monocular camera, (real In actual applications, there may be multiple potholes of varying depths on the same road cross section. At this time, the monocular camera 8 captures multiple abnormal points in the grayscale value of the pixel row. The grayscale values ​​of the multiple pixel rows are compared through the information processing background, and the pothole with the largest grayscale value, that is, the largest depth, is selected to adjust the lighting of the main lamp 605. The technical solution disclosed in the announcement number CN111274939.A can also be referred to for adjustment of the recognition and calculation method of the pothole depth. In addition, the road surface image captured by the monocular camera 8 in this solution is the middle position of the road cross section, and the pothole situation in the middle position is identified. This position is not affected by the shadows of the surrounding trees and buildings, and it is not easy to misidentify. At the same time, the monocular camera 8 does not capture the road surface image in real time all day long, but is regularly turned on by the background management system to capture images. After each image is obtained and the pothole position is identified, the lighting area of ​​the street lamp is adjusted. For example, the monocular camera 8 can be turned on at noon during the day to capture the road surface image. At this time, the lighting is uniform, the shadows of the surrounding obstacles have little impact, and the image recognition is more accurate).

When it is identified that the crown of the street tree is too close to the path of the protective cover 1006, it means that the crown of the street tree is very likely to block the shooting angle of the monocular camera 8 and the lighting angle of the main light 605 and the auxiliary light 704. The background management personnel can arrange personnel to trim the crown of the street tree in advance in a timely manner based on the identified mark points. After the induction radar 11 completes the detection, the reset motor starts to control the rotation of the protective cover 1006 and close it with the track platform 1004 into a straight line. Then the cylinder 1003 starts to pull the track platform 1004 back. Finally, the track platform 1004, the protective cover 1006 and the cleaning roller 1007 are all stored in the stacking bin 12.

[0053] During daily lighting use, the photovoltaic panel 405 in the photovoltaic module senses the angle of sunlight through the photosensitive element 406 to adjust its direction, absorbs sunlight and converts it into electrical energy and stores it in the battery. At night, the battery supplies power to the main lamp 605 and the auxiliary lamp 704. The main lamp 605 illuminates the middle part of the road cross section, and the auxiliary lamp 704 illuminates the roadside curbs on both sides of the road. The control and management background of the street lamp regularly turns on the monocular camera 8 to capture images of the road surface facing the street lamp, and uploads the image data to the information processing background for pixel grayscale and pixel position data processing. After obtaining the location of the potholes on the road, the angle required for the main lamp 605 to be rotated and adjusted is calculated according to the lighting area of ​​the main lamp 605 in the initial state, and the adjustable lighting is adjusted. The component sends out a running command to start the No. 1 motor 601, and through the meshing transmission of the driving gear 602 and the driven gear 603, the main lamp 605 rotates toward the side of the pothole on the road surface, until the lighting direction of the main lamp 605 is on the same axis as the pothole position, focusing on the pothole position. After the rotation adjustment of the main lamp 605 is completed, the torque parameter of the torsion spring 606 is detected by the torque sensor 607, and a signal is sent to the fixed lighting component, and the No. 2 motor 703 is started to control the movable arm 702 to drive the corresponding auxiliary lamp 704 to rotate a certain angle again, so that the lighting area of ​​the auxiliary lamp 704 is adjusted to the curb again. The final effect is to make the key lighting areas of the main lamp 605 and the auxiliary lamp 704 cover the curbs on both sides of the road and the potholes on the road surface respectively;

[0054] When it rains or when water is sprayed on industrial roads to reduce dust and irrigate green belts, rainwater flows into the water storage tank 1301 through the water inlet bucket 1302 and is stored. In the early morning or other fixed time periods every day, the control background starts the rotating motor 401 and the steering motor 403 separately to control the photovoltaic panel 405 to flip and tilt to the side of the road driving direction, and then the No. 4 motor 1002 and the cylinder 1003 in the cleaning component are started together to rotate and pull the track platform 1004, and then the three The No. 1 motor 901 is started, and the meshing connection between the gear roller 902 and the gear ring 903 drives the track table 1004 to rotate from the bottom of the main lamp 605 to the inclined side of the photovoltaic panel 405. The reset motor on the mobile machine 1005 controls the shield 1006 to rotate to a vertical cross shape with the track table 1004. The No. 4 motor 1002 and the cylinder 1003 cooperate to make the cleaning roller 1007 stick to the photovoltaic panel 405. The mobile machine 1005 drives the shield 1006 along the track table 1004. The track table 1004 moves back and forth, and at the same time, the No. 5 motor 1008 drives the cleaning roller 1007 to rotate to wipe and clean the photovoltaic panel 405. At the same time, the No. 1 water supply valve 1307 is opened, the No. 2 water supply valve 1311 is closed, and the pump 1304 pumps the water in the water storage tank 1301 to the nozzle 1309 through the water supply pipe 1305, the branch pipe 1306 and the radiation tube 1308. The nozzle 1309 is driven by the No. 6 motor 1310 to rotate and adjust the water spraying direction to face the photovoltaic panel 405. 5. The cleaning roller 1007 carries water to clean the photovoltaic panel 405. After the photovoltaic panel 405 is cleaned, the No. 3 motor 901 is started again to make the track platform 1004 return to the bottom of the monocular camera 8.

The main lamp 605 and the auxiliary lamp 704 are cleaned in the above manner.

[0055] After all equipment is cleaned, the induction radar 11 is started, and the No. 4 motor 1002 drives the track platform 1004 to flip downward and approach the lamp pole 2. The induction radar 11 detects and identifies obstacles within a certain range of the path passed by the shield 1006, such as the crown of a tall street tree. When it is identified that the crown of the street tree is too close to the path passed by the shield 1006, it means that the crown of the street tree is very likely to block the shooting angle of the monocular camera 8 and the lighting angle of the main light 605 and the auxiliary light 704, and then The detection result is sent to the information processing background, which marks the location of the signal sending point. The background management personnel arrange personnel to trim the crown of the street tree in advance according to the marked point. After the induction radar 11 completes the detection, the reset motor starts to control the rotation of the shield 1006 and close it with the track platform 1004 into a straight line. Then the cylinder 1003 is started to pull the track platform 1004 back. Finally, the track platform 1004, the shield 1006 and the cleaning roller 1007 are all stored in the stacking bin 12.
