[0054] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0055] Refer to Figure 1 As shown, in some embodiments of the present application, this embodiment provides a display management method for a wall-mounted charging pile, including the following steps:

[0056] S100: Determine the installation location of the wall-mounted charging pile, and determine the area to be monitored according to the installation location. Deploy a number of cameras and ambient light sensors evenly within the area to be monitored. Among them, the area to be monitored includes a key monitoring area and a general monitoring area;

[0057] S200: Collect the monitoring data of the cameras located in the general monitoring area, parse the monitoring data, and determine whether to light up the display screen of the wall-mounted charging pile based on the parsing result;

[0058] S300: When it is determined to light up the display screen of the wall-mounted charging pile, collect the ambient light data of all ambient light sensors within the area to be monitored, and construct an ambient light data group. Determine the initial brightness value of the display screen according to the ambient light data group;

[0059] S400: Collect the interaction information between the user and the display screen, and determine whether to optimize the initial brightness value based on the interaction information;

[0060] S500: When it is determined to optimize the initial brightness value, collect the ambient light change data of the key monitoring area and the distance information between the user and the display screen. Determine the optimization coefficient of the initial brightness value according to the ambient light change data and the distance information, and optimize the initial brightness value according to the optimization coefficient to obtain the optimized brightness value.

[0061] It can be understood that the display management method of the wall-mounted charging pile provided in this embodiment can intelligently adjust the brightness of the display screen according to the changes in ambient light and user needs, reflecting the concept of energy conservation and environmental protection. By deploying cameras and ambient light sensors, this embodiment realizes the comprehensive monitoring of the environment around the wall-mounted charging pile. This intelligent monitoring method not only improves the response speed of the charging pile, but also ensures the accuracy and timeliness of the display screen brightness adjustment; by collecting the interaction information between the user and the display screen, the present invention can also perform personalized brightness optimization according to the user's interaction information, significantly improving the use efficiency of the charging pile.

[0062] Specifically, with the geometric center of the display screen as the center of the circle, facing the side of the display screen, extending along the direction perpendicular to the surface of the display screen, a semi-cylindrical space with a radius of r and a height of d is formed; the general monitoring area is the other area in the area to be monitored except the key monitoring area.

[0063] In this embodiment, the preferred values of the radius r and the height d are 30 cm and 60 cm respectively. Such a size design can ensure that the semi-cylindrical space effectively covers the main light change areas around the wall-mounted charging pile, and at the same time will not be too large to cause unnecessary resource consumption.

[0064] It is understandable that the key monitoring area is usually the direct area where the user interacts with the display screen. The light changes and user behaviors in this area have an important impact on the adjustment of the display screen brightness. By monitoring the key monitoring area more carefully, the accuracy of brightness adjustment and the user experience can be further improved.

[0065] Specifically, when parsing the monitoring data and determining whether to light up the display screen of the wall-mounted charging pile based on the parsing result, it includes:

[0066] Parse the monitoring data to obtain the personnel stay duration;

[0067] Compare the personnel stay duration with the standard personnel stay duration, and determine whether to light up the display screen of the wall-mounted charging pile according to the comparison result;

[0068] When the personnel stay duration is greater than or equal to the standard personnel stay duration, light up the display screen of the wall-mounted charging pile;

[0069] Otherwise, do not light up the display screen of the wall-mounted charging pile.

[0070] In this embodiment, the standard personnel stay duration is an empirical value obtained based on historical statistical data and user behavior analysis.

[0071] It is understandable that by monitoring the cameras in the ordinary monitoring area, the personnel activities around the wall-mounted charging pile can be perceived in real time. When there are personnel staying in the area to be monitored and the stay time reaches or exceeds the standard personnel stay duration, the system considers that there is a potential charging demand. At this time, lighting up the display screen can provide charging information for the user and improve the utilization rate of the charging pile. When there are no personnel staying in the area to be monitored or the stay time is short, in order to save energy and extend the service life of the display screen, the system chooses not to light up the display screen. This intelligent lighting strategy not only reflects the concept of energy conservation and environmental protection but also improves the response speed of the charging pile.

[0072] Specifically, when determining the initial brightness value of the display screen according to the environmental light data group, it includes:

[0073] Obtain the average light intensity of the area to be monitored according to the environmental light data group, and determine the basic brightness value of the display screen according to the average light brightness;

[0074] Respectively collect the numbers of environmental light sensors corresponding to greater than, equal to, and less than the average light intensity in the area to be monitored, and record them as the high-brightness number, medium-brightness number, and low-brightness number respectively;

[0075] Respectively obtain the quantity percentages corresponding to the high-brightness number and the low-brightness number, and record them as the high-brightness percentage and the low-brightness percentage respectively;

[0076] Determine whether to adjust the base brightness value according to the high brightness percentage and the low brightness percentage; if so, determine the adjustment coefficient according to the high brightness percentage and the low brightness percentage, and obtain the initial brightness value.

[0077] It can be understood that the high brightness percentage refers to the proportion of the high brightness quantity in the total quantity of high brightness, medium brightness, and low brightness; the low brightness percentage refers to the proportion of the low brightness quantity in the total quantity of high brightness, medium brightness, and low brightness. Through such statistical analysis of the ambient light data group, this embodiment can more comprehensively evaluate the light distribution in the area to be monitored, so as to more accurately determine the initial brightness value of the display screen. When the high brightness percentage is too high or the low brightness percentage is too high, it means that the light distribution in the area to be monitored is uneven, and there may be local overbrightness or overdarkness. At this time, it is necessary to adjust the base brightness value to ensure that the brightness of the display screen can adapt to the overall light environment and improve the user's visual experience.

[0078] Specifically, when determining the base brightness value of the display screen according to the average illumination brightness, it includes:

[0079] Compare the average illumination intensity with the first average illumination intensity and the second average illumination intensity, and determine the base brightness value of the display screen according to the comparison result; wherein, the first average illumination intensity is less than the second average illumination intensity.

[0080] When the average illumination intensity is less than or equal to the first average illumination intensity, the base brightness value of the display screen is set to the first brightness value.

[0081] When the average illumination intensity is greater than the first average illumination intensity and less than or equal to the second average illumination intensity, the base brightness value of the display screen is set to the second brightness value.

[0082] When the average illumination intensity is greater than the second average illumination intensity, the base brightness value of the display screen is set to the third brightness value.

[0083] In this embodiment, the first brightness value, the second brightness value, and the third brightness value are preferred values obtained through experimental data and user experience analysis, and the first brightness value is less than the second brightness value, and the second brightness value is less than the third brightness value. The first average illumination intensity and the second average illumination intensity are empirical values obtained according to historical statistical data and the changing trend of the light environment.

[0084] It can be understood that through such segmented comparison of the average illumination intensity, this embodiment can more finely control the base brightness value of the display screen, so that it can maintain an appropriate brightness level in different light environments. This segmented control strategy not only improves the display effect of the display screen, but also further reflects the concept of energy conservation and environmental protection, avoiding unnecessary energy waste.

[0085] Specifically, when determining whether to adjust the base brightness value according to the high brightness percentage and the low brightness percentage, it includes:

[0086] Calculate the absolute value of the difference between the high brightness percentage and the low brightness percentage, and denote it as the absolute percentage difference;

[0087] Compare the absolute percentage difference with the absolute percentage difference threshold. If the absolute percentage difference is within the absolute percentage difference threshold, it is determined to adjust the base brightness value;

[0088] Otherwise, do not adjust the base brightness value, and use the base brightness value as the initial brightness value.

[0089] In this embodiment, the absolute difference threshold is a threshold set based on historical experience, which is used to measure the degree of difference between the high brightness percentage and the low brightness percentage. When this degree of difference exceeds this threshold, it means that the light distribution in the area to be monitored is too uneven. At this time, it is necessary to adjust the base brightness value to better adapt to the overall light environment and improve the display effect of the display screen. When the degree of difference is within the preset threshold, it is considered that the light distribution in the area to be monitored is relatively uniform. At this time, the base brightness value of the display screen can be directly determined according to the average illumination intensity without additional adjustment.

[0090] Specifically, when determining the adjustment coefficient according to the high brightness percentage and the low brightness percentage and obtaining the initial brightness value, it includes:

[0091] Calculate the ratio of the high brightness percentage to the low brightness percentage, and denote it as the percentage ratio;

[0092] Compare the percentage ratio with the first percentage ratio and the second percentage ratio, and determine the adjustment coefficient according to the comparison result; where the first percentage ratio is less than the second percentage ratio;

[0093] When the percentage ratio is less than or equal to the first percentage ratio, the adjustment coefficient is set to the first adjustment coefficient, and the product value of the first adjustment coefficient and the base brightness value is used as the initial brightness value;

[0094] When the percentage ratio is greater than the first percentage ratio and less than or equal to the second percentage ratio, the adjustment coefficient is set to the second adjustment coefficient, and the product value of the second adjustment coefficient and the base brightness value is used as the initial brightness value;

[0095] When the percentage ratio is greater than the second percentage ratio, the adjustment coefficient is set to the third adjustment coefficient, and the product value of the third adjustment coefficient and the base brightness value is used as the initial brightness value.

[0096] In this embodiment, the first percentage ratio and the second percentage ratio are empirical values obtained based on historical statistical data and light distribution characteristics. The first adjustment coefficient is greater than the second adjustment coefficient, and the second adjustment coefficient is greater than the third adjustment coefficient.

[0097] It can be understood that when the light distribution is extremely uneven, a large adjustment coefficient is used to significantly adjust the basic brightness value, which can quickly improve the display effect of the display screen; while when the light distribution is relatively uniform, a small adjustment coefficient is used to finely adjust the basic brightness value, which can avoid unnecessary energy waste while maintaining the display effect. This dynamic adjustment strategy based on light distribution characteristics not only improves the adaptability and display effect of the display screen, but also further reflects the concept of energy conservation and environmental protection.

[0098] Specifically, when determining whether to optimize the initial brightness value based on interaction information, it includes:

[0099] The interaction information includes the operation duration and operation frequency of the user touching the display screen;

[0100] Compare the operation duration and operation frequency with the standard operation duration and standard operation frequency respectively, and determine whether to optimize the initial brightness value according to the comparison result;

[0101] If the operation duration is greater than the standard operation duration and the operation frequency is less than the standard operation frequency, it is determined to optimize the initial brightness value;

[0102] Otherwise, do not optimize the initial brightness value.

[0103] It can be understood that the standard operation duration and standard operation frequency are empirical values obtained based on statistical analysis of a large amount of user behavior data. By monitoring the operation duration and operation frequency of the user touching the display screen, this embodiment can real-time sense the usage habits and needs of the user for the display screen. When the operation duration of the user touching the display screen is long and the operation frequency is low, the system believes that the user may be carefully reading the information on the display screen. At this time, optimizing the initial brightness value can further improve the user's reading experience.

[0104] Specifically, when determining the optimization coefficient of the initial brightness value according to the ambient light change data and distance information, and optimizing the initial brightness value according to the optimization coefficient to obtain the optimized brightness value, it includes:

[0105] Analyze the ambient light change data to obtain the comprehensive ambient light change rate;

[0106] The distance information is the actual distance between the user's eyes and the display screen;

[0107] Calculate the brightness influence factor according to the comprehensive ambient light change rate and the actual distance;

[0108] Compare the brightness influence factor with the historical data. If there is a historical brightness influence factor in the historical data that is the same as the brightness influence factor, adjust the initial brightness value according to the historical optimization coefficient corresponding to the historical brightness influence factor, and use the product value of the historical optimization coefficient and the initial brightness value as the optimized brightness value;

[0109] If there is no historical brightness influence factor in the historical data that is the same as the brightness influence factor, determine the optimization coefficient of the initial brightness value according to the brightness influence factor.

[0110] In this embodiment, the brightness influence factor is obtained by weighted calculation of the comprehensive change rate of environmental light and the actual distance. The unit of the actual distance is meters. The comprehensive change rate of environmental light reflects the dynamic change of the ambient light around the wall-mounted charging pile, while the actual distance reflects the viewing distance of the user to the display screen. These two factors together determine the adjustment requirement of the display screen brightness. By comprehensively considering these two factors, this embodiment can more accurately evaluate the adjustment range of the display screen brightness, so as to ensure that the optimized brightness value can not only adapt to the change of environmental light, but also meet the viewing needs of users.

[0111] In this embodiment, the historical data is a database obtained based on the corresponding relationship between past brightness influence factors and optimization coefficients. By comparing the historical data, the historical optimization coefficient matching the current brightness influence factor can be quickly found, so as to realize the rapid adjustment of the initial brightness value. When there is no historical brightness influence factor in the historical data that matches the current brightness influence factor, it is necessary to re-determine the optimization coefficient according to the current brightness influence factor to ensure that the optimized brightness value can accurately reflect the change of environmental light and the needs of users.

[0112] Specifically, when determining the optimization coefficient of the initial brightness value according to the brightness influence factor, it includes:

[0113] Construct a correspondence table between the brightness influence factor and the optimization coefficient;

[0114] Search for the target optimization coefficient matching the brightness influence factor in the correspondence table, and use the target optimization coefficient as the optimization coefficient of the initial brightness value, and use the product value of the optimization coefficient and the initial brightness value as the optimized brightness value.

[0115] It can be understood that the correspondence table between the brightness influence factor and the optimization coefficient is a carefully designed and experimentally verified table. It is based on a large amount of experimental data and user feedback to ensure that the brightness of the display screen can be adjusted most reasonably under different light environments and user interactions.

[0116] In this embodiment, when the value of the brightness influence factor is 3, the matching target optimization coefficient is 1.05; when the value of the brightness influence factor is 5, the matching target optimization coefficient is 1.15, and so on. When the value of the brightness influence factor is larger, it means that the environmental light changes more violently or the user's viewing distance is farther. At this time, a larger optimization coefficient is required to adjust the initial brightness value to ensure that the brightness of the display can adapt to this change and improve the user's visual comfort. On the contrary, when the value of the brightness influence factor is smaller, it means that the environmental light is relatively stable or the user's viewing distance is closer. At this time, the initial brightness value can be fine-tuned with a smaller optimization coefficient to avoid unnecessary energy waste. This strategy of dynamically determining the optimization coefficient according to the brightness influence factor improves the adaptability and energy-saving effect of the display.
