When the coefficient is 0, it corresponds to the minimum brightness of the street lamp; when the coefficient is 1, it corresponds to the maximum brightness of the street lamp.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. In the present invention, two lampshades symmetrically arranged on both sides of the lamp frame work together with the internal LED module to achieve uniform lighting of the two side areas. Through the unique brightness control mechanism, not only can the degree of light focus be adjusted by spacing control to adapt to different lighting needs, but the servo motor-driven rotating rod linkage can also be used to drive the light angle and brightness to be adjusted synchronously to adapt to changes in the surrounding environment, such as light intensity and pedestrian flow, thereby realizing adaptive brightness control of smart street lights. This design not only makes the lighting effect more in line with actual needs and greatly improves the lighting efficiency, but also places special emphasis on energy saving. The built-in wind fan device uses natural wind energy to power the system, and the photovoltaic panel in front absorbs solar energy as a supplement, realizing the comprehensive application of multiple energy sources, further enhancing the sustainability and environmental protection of the system. The infrared sensor monitors the pedestrian flow and the light sensor monitors the light intensity, and automatically adjusts the brightness and angle, which not only reduces unnecessary energy consumption, but also ensures that the irradiated area is always at a suitable light level, and the adaptability and intelligence are effectively improved.

[0021] 2. In the present invention, two modes of electric regulation and mechanical regulation are selected according to the regulation requirements. After mechanical regulation is selected, the connection frame and the lampshade are controlled to be opened to a certain distance, and the light brightness is adjusted by using the adjustment lens inside the connection frame. By controlling the position of the adjustment lens, the focusing degree of the light can be changed. When the adjustment lens is close to the light source, the light can be focused into a more concentrated light beam, thereby providing higher brightness in a specific area. On the contrary, when the adjustment lens is far away from the light source, the light will be more dispersed, illuminating a larger area. The lighting effect can be flexibly adjusted without changing the characteristics of the light source itself, providing a more energy-saving control method for the brightness adjustment of smart street lamps.

[0022] 3. In the present invention, by opening the limit switch, a positioning connection is formed between the inside of the bevel gear 1 and the surface of the driving rod. When the driving rod rotates, the two bevel gears 1 cooperate to transmit the transmission, so that the transmission rod rotates inside the fixed frame, and then cooperates with the two mutually cooperating bevel gears 2 to drive the rotating frame to rotate. The rotating frame is used to adjust the lighting angle of the lampshade, thereby realizing adaptive adjustment of the illuminated area, further improving the lighting effect of the smart street lamp, and when adjusting the angle of the lampshade, the two synchronous gears and the bevel gears 3 at both ends of the transmission telescopic rod are used to synchronize the connection frame and the lampshade, so that the adjustment lens inside the connection frame is used to adjust the brightness of the lampshade after the angle adjustment, while improving the lighting range of the smart street lamp, it also improves the flexibility of light brightness adjustment of the smart street lamp.

[0023] 4. The smart street light system of the present invention monitors the light intensity and pedestrian flow in real time by arranging light sensors and infrared sensors at different heights, significantly improving lighting efficiency and user experience. The system first uses light sensors to record the maximum and minimum values ​​of the time series light intensity data, and uses a normalized calculation formula to normalize the light intensity to ensure that the data is smoothly transmitted in the [0,1] interval; at the same time, when the pedestrian flow is lower than the preset threshold, the system calculates the pedestrian flow impact value according to the formula, reasonably reduces the lighting effect of this part of the time, thereby saving energy; and when the pedestrian flow exceeds the threshold, the system uses a broken line calculation to ensure that it can respond efficiently to high-demand periods. The entire process calculates the brightness adaptive adjustment coefficient through a formula, which significantly allows the street light brightness to be dynamically adjusted according to the actual lighting and pedestrian flow needs, achieving the intelligent effect of "energy saving when there are few people, moderate light, brightening when there are many people, and ensuring safety".

[0024] Through such supervision, smart street lights can not only automatically reduce the light intensity when the light is sufficient, but also maintain sufficient brightness only when necessary, effectively reducing energy consumption and electricity costs, while avoiding excessive lighting in unmanned areas at night and reducing light pollution; and for high passenger flow periods or areas with specific needs, the lighting effect can be instantly enhanced to ensure traffic safety and comfort. The careful setting and application of weight factors make the overall lighting strategy more scientific, efficient, and energy-saving, achieving a perfect combination of lighting and environmental protection, convenience and safety.

On the contrary, when the adjustment lens 10 is far away from the light source, the light will be more dispersed, illuminating a larger area. The lighting effect can be flexibly adjusted without changing the characteristics of the light source itself, providing a more energy-saving control method for brightness adjustment of the smart street lamp.

[0039] Specifically, a servo motor 11 is fixedly installed on the upper part of the interior of the lamp holder 1, and a driving rod 12 is fixedly installed on the output shaft of the servo motor 11 through a coupling.

[0040] It should be noted that when the adjustment frame 6 is controlled to move up and down inside the movable groove 17, the driving rod 12 drives the driving gear 13 to rotate, and at the same time, the driving ends of the two micro-electric cylinders are used to push the two transmission gears 14 downward. At this time, the surfaces of the two transmission gears 14 are respectively meshed with the surfaces of the two driven gears 15 and the two sides of the surface of the driving gear 13.

By adjusting the positions of the two adjustment frames 6, the two adjustment lenses 10 are respectively located at different distances below the two lampshades 4, thereby playing a flexible adjustment role in the brightness.

[0041] Furthermore, in order to further improve the lighting effect of the smart street lamp on the road surface, a transmission rod 20 is rotatably arranged inside the fixed frame 2, and one end of the transmission rod 20 extends to the inside of the lamp frame 1, and a bevel gear 18 is fixedly arranged on one end of the transmission rod 20 located inside the lamp frame 1 and above the surface of the driving rod 12, and the surfaces of the two bevel gears 18 are meshed with each other, and a bevel gear 2 19 is fixedly arranged on the other end of the transmission rod 20 and one side of the rotating frame 3, and the surfaces of the two bevel gears 2 19 are meshed for transmission;

[0043] It should be noted that a limit switch is arranged inside the bevel gear 18 arranged on the surface of the driving rod 12. By turning on the limit switch, a positioning connection is formed between the inside of the bevel gear 18 and the surface of the driving rod 12. When the driving rod 12 rotates, the two bevel gears 18 cooperate to transmit, so that the transmission rod 20 rotates inside the fixed frame 2, and then cooperates with the two mutually cooperating bevel gears 2 19 to drive the rotating frame 3 to rotate, and the rotating frame 3 is used to adjust the lighting angle of the lampshade 4, so as to realize adaptive adjustment of the illuminated area, further improve the lighting effect of the smart street lamp, and when adjusting the angle of the lampshade 4, the two synchronous gears 21 and the bevel gears 3 23 at both ends of the transmission telescopic rod 22 are used to realize synchronous adjustment between the connecting frame 8 and the lampshade 4, so as to use the adjustment lens 10 inside the connecting frame 8 to adjust the brightness of the lampshade 4 after the angle adjustment, while improving the lighting range of the smart street lamp, it also improves the flexibility of light brightness adjustment of the smart street lamp.

At this time, as the driving rod 12 rotates, the rotating base 25 is rotated synchronously at the top of the lamp stand 1, so that the two ventilation flow channels inside the wind power equipment frame 28 are adjusted to follow the wind direction and contact the annular clamps 27 to limit and clamp the driving rod 12, thereby improving the wind energy collection effect of the wind fan blades 29 inside the wind power equipment frame 28.

[0047] Furthermore, the top of the lamp stand 1 passes through the interior of the wind power equipment frame 28 and extends upward, and a photovoltaic equipment frame 30 is also fixedly installed on the top of the lamp stand 1.

The light sensors arranged at each height position obtain the light intensity of the smart street lamp at each monitoring time in each area position in real time, and the infrared sensors arranged at each height position obtain the pedestrian flow at each monitoring time in each area position in real time, so as to obtain the light intensity and pedestrian flow data of the smart street lamp at each monitoring time in each area position, which are respectively recorded as I i j and P i j , i represents the number of the smart street lamp corresponding to each area position, i = 1, 2, ..., n, n represents the total number of the area position number, j represents the number of each monitoring time, j = 1, 2, ..., m, m represents the total number of the monitoring time number;

[0050] Get the maximum and minimum light intensity of the smart street lamp at each monitoring time in each area from the database, and record them as Imax i j and Imin i j , according to the formula IN i j =(I i j -Imin i j ) / (Imax i j -Imin i j ) Calculate the normalized value IN of the light intensity of the smart street lamp corresponding to each area and each monitoring time i j ;

[0051] A pedestrian flow threshold PY is artificially set for the pedestrian flow at each monitoring time in each area location corresponding to the smart street lamp. When the pedestrian flow at each monitoring time in each area location corresponding to the smart street lamp is less than the flow threshold PY, according to the formula PF ij =k1×P i j / PY calculates the pedestrian flow impact value PF of the smart street lamp corresponding to each area and each monitoring time i j , where k1 is a constant less than 1;

[0053] According to the formula L i j =a×IN i j +b×PF i j Calculate the brightness adaptive adjustment coefficient L of the smart street lamp corresponding to each monitoring time in each area position i j , where a and b represent the corresponding weight coefficients respectively.

[0054] A linear relationship between the brightness adaptive adjustment coefficient of the smart street lamp at each monitoring time in each area location and the street lamp brightness is established, and the value range of the brightness adaptive adjustment coefficient of the smart street lamp at each monitoring time in each area location is set to [0,1]. When the coefficient is 0, it corresponds to the minimum brightness of the street lamp; when the coefficient is 1, it corresponds to the maximum brightness of the street lamp.

[0055] In a specific embodiment, the present invention arranges light sensors and infrared sensors at different heights to monitor light intensity and pedestrian flow in real time, significantly improving lighting efficiency and user experience. The system first uses light sensors to record the maximum and minimum values ​​of time series light intensity data, and uses a normalized calculation formula to normalize the light intensity to ensure that the data is smoothly transmitted in the [0,1] interval; at the same time, when the pedestrian flow is lower than the preset threshold, the system calculates the pedestrian flow impact value according to the formula, reasonably reduces the lighting effect of this part of the time, thereby saving energy; and when the pedestrian flow exceeds the threshold, the system uses a broken line calculation to ensure that it can efficiently respond to high-demand periods. The entire process calculates the brightness adaptive adjustment coefficient through a formula, which significantly allows the street lamp brightness to be dynamically adjusted according to the actual lighting and pedestrian flow needs, achieving the intelligent effect of "energy saving when there are few people, moderate light, brightening when there are many people, and ensuring safety".

[0056] Through such supervision, smart street lights can not only automatically reduce the light intensity when the light is sufficient, but also maintain sufficient brightness only when necessary, effectively reducing energy consumption and electricity costs, while avoiding excessive lighting in unmanned areas at night and reducing light pollution; and for high passenger flow periods or areas with specific needs, the lighting effect can be instantly enhanced to ensure traffic safety and comfort. The careful setting and application of weight factors make the overall lighting strategy more scientific, efficient, and energy-saving, achieving a perfect combination of lighting and environmental protection, convenience and safety.
