[0019] 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 application can be combined with each other without conflict.

[0020] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0021] Example 1 Embodiment 1 of the present invention provides an LED lighting dimming method, comprising: Get the first area number information; Obtaining first light intensity information according to the first area number; According to the first light intensity information, second light intensity information is obtained through preset data processing; Obtaining third light intensity information by using a preset mean value algorithm according to the second light intensity information; Determine whether the third light intensity information is lower than a preset first light intensity threshold; if so, obtain the first infrared information; determining a lighting mode according to the first infrared information; The target light intensity information of the LED is set according to the lighting mode and the second light intensity information.

[0022] Figure 1 A flow chart of a high-efficiency flicker-free LED lighting intelligent dimming method according to a more specific embodiment of the present invention is shown.

[0023] like Figure 1 As shown, the present invention discloses a high-efficiency flicker-free LED lighting intelligent dimming method, the method comprising: S102, obtaining first area number information; S104, obtaining first light intensity information according to the first area number; S106, obtaining second light intensity information through preset data processing according to the first light intensity information; S108, obtaining third light intensity information through a preset mean algorithm according to the second light intensity information; S110, judging whether the third light intensity information is lower than a preset first light intensity threshold; S112, if so, obtaining first infrared information; S114, determining a lighting mode according to the first infrared information; S116, setting the LED light emission target light intensity information according to the lighting mode and the second light intensity information.

[0024] It should be noted that the first area number information is the number of the road section, and the urban lighting LED on the road section is encoded and recorded according to the area number, that is, the urban lighting LEDs on the same section of road have the same area number; the first light intensity information is the light intensity value of the ambient brightness measured by the urban lighting LED; the second light intensity information is the light intensity value obtained by data filtering the first light intensity information of the urban lighting LED with the same area number; the third light intensity information is the average value of the second light intensity information of the urban lighting LED with the same area number calculated according to the preset mean algorithm; the first infrared information is the detection result of the infrared sensor measured by the urban lighting LED toward the ground; the target light intensity information is the luminous light intensity value set for the urban lighting LED.

[0025] In this embodiment, first, according to the area number of the road section, the first light intensity information measured by the city lighting LED on the road section is collected and summarized to indicate the current brightness of the road section. The entire road section is used as the light intensity measurement and luminous adjustment unit, firstly, to improve the accuracy of the ambient brightness measurement; secondly, to make the luminous conditions of adjacent city lighting LEDs on the same road section similar, to avoid sudden changes in luminous brightness, thereby improving the traffic experience of pedestrians or motor vehicles on the road. Secondly, according to the preset data processing strategy, the first light intensity information measured by the city lighting LED on the road section with the first area number is filtered to obtain the second light intensity information of the city lighting LED on the road section, so that the second light intensity information corresponding to the adjacent city lighting LEDs is similar; then the second light intensity information of the city lighting LED on the road section is calculated according to the preset mean algorithm to obtain the arithmetic light intensity mean, which is recorded as the third light intensity information. Then, when it is judged that the third light intensity information is lower than the preset first light intensity threshold, it means that the ambient brightness of the road section with the first area number is lower than the preset brightness level, and it is necessary to illuminate the road section by lighting the city lighting LED; at this time, the infrared information on the road surface in the road section is measured by the infrared sensor on the lighting equipment, and the infrared thermal imaging map is drawn according to the infrared information. By analyzing the thermal imaging map, it is determined whether there are motor vehicles, non-motor vehicles, pedestrians, etc. in the road section, so as to determine the lighting mode of the city lighting LED. Finally, in the lighting mode corresponding to the city lighting LED, the target light intensity value of the LED is adjusted in real time according to the size of the second light intensity information and the traffic conditions of motor vehicles, non-motor vehicles, pedestrians, etc. in the road section. On roads without pedestrians and motor vehicles, the LED light intensity is in a low state to achieve the purpose of saving electric energy. On roads with only motor vehicles, the LED light intensity is adjusted according to the second light intensity information to meet the lighting needs when motor vehicles pass. On roads with pedestrians or non-motor vehicles, the LED light intensity is in a high state to improve the traffic experience of pedestrians and non-motor vehicles. Therefore, the present invention automatically switches the working mode of the urban lighting LED by measuring and analyzing the road light intensity and the traffic conditions of pedestrians and vehicles, realizes intelligent adjustment of the LED brightness, and achieves the purpose of reducing electricity costs.

[0026] Figure 2 A flow chart of data processing of first light intensity information provided by an embodiment of the present invention is shown.

[0027] According to an embodiment of the present invention, Figure 2As shown, according to the first light intensity information, the second light intensity information is obtained through preset data processing, specifically: S202, obtaining the first noise information and the second noise information; S204, obtaining the covariance information according to the first noise information; S206, obtaining the gain information according to the second noise information and the covariance information; S208, updating the covariance information according to the gain information; S210, obtaining the second light intensity information according to the first light intensity information and the gain information.

[0028] It should be noted that the first noise information and the second noise information are two adjustment parameters in the data processing algorithm, wherein the first noise information is also called process noise covariance, and the second noise information is also called measurement noise covariance; the covariance information is the covariance value in the data processing algorithm; and the gain information is the calculated gain in the data processing algorithm. The formula of the data processing flow is as follows: P N =P N-1 + Q1; G N =P N / ( P N + Q2); Y N = Y N-1 + G N * ( X N – Y N-1 ); P N = (1 - G N ) * P N ; P N is the covariance in this round of operation; P N-1 is the covariance in the previous round of operation; Q1 is the first noise information; Q2 is the second noise information; G N is the gain information in this round of operation; Y N is the result of this round of calculation, i.e., the second light intensity information of the current urban lighting LED; Y N-1 is the result of the previous round of calculation, that is, the second light intensity information of the adjacent previous city lighting LED; X N It is the input in this round of operation, that is, the first light intensity information of the current urban lighting LED.

[0029] In this embodiment, it can be seen from the above formula that the structure of the second light intensity information of the city lighting LED is highly correlated with the second light intensity information of the adjacent previous city lighting LED and the first light intensity information of the current city lighting LED. That is, the above formula can be used to reduce the deviation value of the second light intensity information of the two adjacent city lighting LEDs, thereby achieving the purpose of filtering and denoising. In addition, the gain information GN As the output Y of this round N The weighted value in the calculation formula will directly affect the result of the filtering output; and the first noise information Q1 and the second noise information Q2 will affect the gain information G N That is, the first noise information Q1 and the second noise information Q2 can adjust the output of the filter. Further, the first noise information Q1 and the second noise information Q2 are adjustable values. According to the input or output of data processing, the first noise information Q1 or the second noise information Q2 is adjusted in real time to achieve the purpose of improving the filtering effect.

[0030] Figure 3 A flowchart for confirming a lighting mode provided by an embodiment of the present invention is shown.

[0031] According to an embodiment of the present invention, Figure 3 As shown, according to the first infrared information, the lighting mode is determined, specifically: S302, according to the first infrared information, a first thermal imaging image is obtained; S302, according to the thermal imaging image, whether there is a thermal object; S304, if not, the lighting mode is set to the standby mode; S306, if yes, the size information, moving speed information, and position information of the thermal object are determined according to the thermal imaging image; S308, according to the size information, the moving speed information and the position information, it is determined whether the thermal object is a motor vehicle; S310, if yes, the lighting mode is set to the motor vehicle mode; S312, if not, the lighting mode is set to the non-motor vehicle mode.

[0032] It should be noted that the first infrared information detected by the infrared sensor of at least one urban lighting device is used to draw a thermal image. By analyzing the thermal image, it is found whether there is an object with a temperature higher than the ambient temperature in the thermal image, that is, it is determined whether there is a thermal object; if not, it means that there are no motor vehicles and non-motor vehicles including pedestrians in the current road section, and the lighting mode of the urban lighting LED is set to standby mode; if yes, it means that there are motor vehicles or non-motor vehicles including pedestrians in the current road section. When it is determined that there is a thermal object in the road section, the size of the thermal object, the moving speed of the thermal object and the location information of the thermal object are obtained through image analysis technology to analyze and determine whether the current thermal object is a motor vehicle; if yes, the lighting mode of the urban lighting LED is set to the motor vehicle mode; if not, the lighting mode of the urban lighting LED is set to the non-motor vehicle mode.

[0033] According to an embodiment of the present invention, it also includes: the lighting mode is a working mode set when the LED is in a lit state, including at least a standby mode, a motor vehicle mode and a non-motor vehicle mode; when in the standby mode, the LED is set to a low brightness state; when in the motor vehicle mode, the LED brightness is set according to the second light intensity information; when in the non-motor vehicle mode, the LED is set to a high brightness state.

[0034] It should be noted that when the city lighting LED is in the lit state, it includes at least three working modes, namely standby mode, motor vehicle mode and non-motor vehicle mode. When in standby mode, it means that there are no motor vehicles and non-motor vehicles including pedestrians on the road. At this time, the target luminous brightness of the LED is set to a lower brightness value to achieve the purpose of saving electric energy. When in motor vehicle mode, it means that there are only motor vehicles on the road, and there are no pedestrians or non-motor vehicles. At this time, the target luminous brightness of the LED is adjusted according to the second light intensity information, so that the LED provides urban lighting conditions that meet the traffic needs for motor vehicles, avoids the situation of being too dark or too bright, and improves the traffic experience of motor vehicle drivers. When in non-motor vehicle mode, it means that there are pedestrians or non-motor vehicles on the road. At this time, the target luminous brightness of the LED is set to a higher brightness value to provide good urban lighting conditions for pedestrians or non-motor vehicles, so as to improve the traffic experience of pedestrians and non-motor vehicle drivers.

[0035] Figure 4 A flow chart of setting the target light intensity in the standby mode provided by an embodiment of the present invention is shown.

[0036] According to an embodiment of the present invention, Figure 4 As shown, when in the standby mode, the LED is set to a low brightness state, specifically: S402, determine that the lighting mode is the standby mode; S404, determine whether the second light intensity information exceeds the preset second light intensity threshold; S406, if not, set the target light intensity information to the first target light intensity threshold; S408, if yes, set the target light intensity information to 0.

[0037] It should be noted that, in the embodiment, the city lighting LED in standby mode will determine whether the second light intensity information exceeds the preset second light intensity threshold; if not, it means that the brightness of the current road is in a dark state, and the basic brightness condition needs to be supplemented by the city lighting LED, therefore, the target light intensity information is set to the first target light intensity threshold to provide a certain lighting brightness; if yes, it means that the brightness condition of the current road meets the basic requirements, therefore, the target light intensity information is set to 0. It should be noted that setting the target light intensity information to 0 is not equivalent to turning off the LED, but putting the LED in an extremely low current conduction state, in which the conditions for quickly adjusting the LED brightness are available.

[0038] Figure 5 A flow chart of setting target light intensity in a motor vehicle mode provided by an embodiment of the present invention is shown.

[0039] According to an embodiment of the present invention, Figure 5 As shown, when in the motor vehicle mode, the LED brightness is set according to the second light intensity information, specifically: S502, when the lighting mode is determined to be the motor vehicle mode; S504, according to the second light intensity information, searching the preset light intensity correspondence table, and setting the target light intensity information; S506, obtaining the moving speed information; S508, determining the time threshold according to the moving speed information; S510, obtaining the first time information; S512, determining whether the first time information exceeds the time threshold; S514, if so, setting the light intensity reduction flag.

[0040] It should be noted that, in the embodiment, the city lighting LED in the motor vehicle mode searches the preset light intensity correspondence table according to the second light intensity information to obtain the brightness that needs to be supplemented under the brightness condition of the second light intensity information, that is, the target light intensity information of the city lighting LED. Then, according to the moving speed information obtained by analyzing the thermal imaging image, the time required for the motor vehicle to pass through the current road section is calculated and recorded as the time threshold. The first time information is the total time for the motor vehicle to enter the current road. If the first time information exceeds the time threshold, it means that the motor vehicle may have left the current road. Therefore, a flag that allows the light intensity to be lowered is set, indicating that the city lighting LED can perform a light brightness lowering operation. Furthermore, for the city lighting LED in the motor vehicle mode, when there is a lack of a flag that allows the light intensity to be lowered, the city lighting LED cannot perform a light brightness lowering operation to avoid the risk of passing due to deterioration of lighting conditions during the passage of motor vehicles on the road.

[0041] Figure 6 A flow chart of setting target light intensity in non-motor vehicle mode provided by an embodiment of the present invention is shown.

[0042] According to an embodiment of the present invention, Figure 6 As shown, when in non-motor vehicle mode, the LED is set to a high brightness state, specifically: S602, determining that the lighting mode is non-motor vehicle mode; S604, obtaining position information; S606, determining distance information based on the position information; S608, determining whether the distance information exceeds a preset distance threshold; S610, if so, setting the target light intensity information to a second target light intensity threshold; S612, if not, setting the target light intensity information to a third target light intensity threshold.

[0043] It should be noted that, in the embodiment, the city lighting LED in the non-motor vehicle mode adjusts the luminous brightness according to the distance between the pedestrian or non-motor vehicle and the city lighting device. According to the position information in the thermal imaging image, the distance between the pedestrian or non-motor vehicle and the current city lighting device is analyzed to determine whether the distance information exceeds the preset distance threshold; if so, it means that the pedestrian or non-motor vehicle has moved away from the current city lighting device, that is, the current city lighting device adjusts the brightness downward and does not cause visibility reduction to the pedestrian or non-motor vehicle driver, therefore, the target light intensity information is set to the second target light intensity threshold to achieve energy saving; if not, it means that the pedestrian or non-motor vehicle is close to the current city lighting device, that is, the current city lighting device needs to provide lighting assistance for the pedestrian or non-motor vehicle driver, therefore, the target light intensity information is set to the third target light intensity threshold, thereby providing bright road conditions to improve the pedestrian and non-motor vehicle traffic experience.

[0044] According to an embodiment of the present invention, the first target light intensity threshold is lower than the second target light intensity threshold, and the second target light intensity threshold is lower than the third target light intensity threshold.

[0045] According to an embodiment of the present invention, the first light intensity information is an electrical signal obtained by converting a light intensity signal through a photoelectric converter, and is represented by a voltage value or an analog-to-digital conversion value.

[0046] It should be noted that a photoelectric converter is provided in the urban lighting equipment to convert the measured ambient light intensity into an electrical signal, wherein the stronger the electrical signal, the higher the brightness. As an implementation, the electrical signal of the photoelectric converter is represented by a voltage value. As another implementation, the electrical signal is converted into a digital signal by an analog-to-digital converter, that is, the electrical signal of the photoelectric converter is represented by an analog-to-digital conversion value.

[0047] It is worth mentioning that this solution also includes: when determining that the lighting mode is a motor vehicle mode; obtaining humidity information; determining whether the humidity information exceeds a preset humidity threshold; if so, adjusting the target light intensity information upward according to the humidity information.

[0048] It should be noted that, as an implementation method, a humidity sensor is provided in the urban lighting equipment to detect the ambient humidity, which is recorded as humidity information. When the urban lighting LED is in the motor vehicle mode, it is determined whether the humidity information exceeds the preset humidity threshold. If so, it means that the current ambient humidity is high and there is water on the ground, which affects the motor vehicle driver's observation of the road condition; therefore, the target light intensity information is adjusted upward according to the humidity information, and the lighting brightness is increased to provide the motor vehicle driver with a better road condition observation experience.

[0049] It is worth mentioning that this solution also includes: when determining that the lighting mode is a motor vehicle mode; obtaining visibility light intensity information; determining whether the visibility light intensity information is lower than a preset visibility light intensity threshold; if so, adjusting the target light intensity information upward according to the visibility light intensity information.

[0050] It should be noted that, as an implementation method, a visibility detection device is provided in the urban lighting equipment, including a set light intensity emitting light source and a photoelectric converter. The photoelectric converter receives the emitted light of the preset light intensity and obtains the visibility light intensity information; wherein the greater the visibility light intensity information, the weaker the received obstruction, that is, the higher the visibility. It is judged whether the visibility light intensity information is lower than the preset visibility light intensity threshold. If so, it indicates that the visibility of the current road is cleared. Therefore, the target light intensity information is adjusted upward according to the visibility light intensity information, and a better road condition observation experience is provided for the motor vehicle driver by increasing the lighting brightness.

[0051] The present invention provides a high-efficiency flicker-free LED lighting intelligent dimming method. First, first light intensity information collected by urban lighting LEDs in a corresponding area is obtained according to first area number information; secondly, the first light intensity information is processed by a preset data processing strategy to obtain second light intensity information; the second light intensity information is calculated by a preset mean algorithm to obtain third light intensity information; then, when it is determined that the third light intensity information is lower than a preset first light intensity threshold, first infrared information is collected and processed, and a lighting mode is determined according to the first infrared information; finally, according to the lighting mode and the second light intensity information, the luminous target light intensity information of the LED is set; the present invention automatically switches the working mode of the urban lighting LED by measuring and analyzing the road light intensity and the traffic conditions of pedestrians and vehicles, thereby realizing intelligent adjustment of the LED brightness and achieving the purpose of reducing electricity costs.
