[0021] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein ambient light intensity data of an environment in which the outdoor display is located is obtained, and the ambient light intensity data is analyzed to determine characteristics of the light intensity data, including: obtaining ambient light intensity data of the environment in which the outdoor display is located, and constructing a time-progressive ambient light intensity change curve based on the ambient light intensity data; determining a maximum light intensity value and a minimum light intensity value from the ambient light intensity change curve, and determining an average light intensity value based on the ambient light intensity data; and determining the maximum light intensity value, the minimum light intensity value, and the average light intensity value as characteristics of the light intensity data.

By analyzing the ambient light intensity change curve, the maximum and minimum light intensity values ​​on the curve can be determined. These values ​​represent the extreme lighting conditions in the environment and help determine the upper and lower limits of the display brightness. Further analysis of the ambient light intensity data can calculate the average light intensity value. This value represents the overall level of ambient light and provides a reference for subsequent brightness control. The maximum light intensity value, the minimum light intensity value, and the average light intensity value are determined as characteristics of the light intensity data.

This not only improves the adaptability and visibility of the display in outdoor environments, but also helps save energy and reduce emissions, extending the service life of the display.

[0023] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein the light intensity of an environment is evaluated based on light intensity data characteristics to obtain a light intensity evaluation value, including: obtaining a preset standard light intensity average value, calculating the difference between the light intensity average value and the standard light intensity average value, and evaluating the difference to obtain a first evaluation value; calculating the difference between the maximum light intensity value and the minimum light intensity value, and evaluating the difference to obtain a second evaluation value; and adding the first evaluation value and the second evaluation value to obtain a light intensity evaluation value of the environment.

[0024] Specifically, the average light intensity of a preset standard is obtained as a reference value to evaluate the level of ambient light intensity; by calculating the difference between the average light intensity of the ambient light and the preset standard value, an evaluation value can be obtained, which represents the degree of deviation between the ambient light intensity and the standard value; the difference between the average light intensity and the average standard light intensity is evaluated; the difference between the maximum light intensity value and the minimum light intensity value in the environment is calculated to evaluate the range of change and stability of the lighting conditions; the difference between the maximum light intensity value and the minimum light intensity value is evaluated to determine the degree of fluctuation and stability of the ambient light intensity, providing more comprehensive information for evaluating the ambient light conditions; the evaluation values ​​of the difference between the average light intensity value and the difference between the maximum and minimum light intensity values ​​are added together to obtain the ambient light intensity evaluation value. This comprehensive evaluation value can reflect the overall situation of the ambient light intensity and provide a reference for subsequent brightness control and adjustment. This step achieves a quantitative analysis and evaluation of the ambient light intensity level by comparing and evaluating the ambient light intensity data with the preset standard value.

[0025] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein the method determines the initial brightness of the outdoor display based on the light intensity evaluation value, including: obtaining a preset light intensity evaluation value L0, and obtaining a preset difference value L1, a preset difference value L2, a third preset difference value L3, and a fourth preset difference value L4, and L1 < L2 < L3 < L4, a preset initial brightness value k1, a preset initial brightness value k2, a third preset initial brightness value k3, and a fourth preset initial brightness value k4, and k1 < k2 < k3 < k4; determining the light intensity evaluation value ΔL of the environment, and according to The preset initial brightness value ki is selected as the initial brightness of the outdoor display based on the difference between the ambient light intensity evaluation value △L and the preset light intensity evaluation value L0; when △L-L0≤L1, the preset initial brightness value k1 is selected as the initial brightness of the outdoor display; when L1<△L-L0≤L2, the preset initial brightness value k2 is selected as the initial brightness of the outdoor display; when L2<△L-L0≤L3, the preset initial brightness value k3 is selected as the initial brightness of the outdoor display; when L3<△L-L0≤L4, the preset initial brightness value k4 is selected as the initial brightness of the outdoor display.

[0026] Specifically, a preset light intensity evaluation value L0 and a series of preset difference values ​​L1, L2, L3 and L4 are obtained, where L1 < L2 < L3 < L4. These preset values ​​are used to compare the difference between the ambient light intensity evaluation value △L and the preset values; preset initial brightness values ​​k1, k2, k3 and k4 are set, where k1 < k2 < k3 < k4. These preset initial brightness values ​​correspond to the initial brightness levels of the display under different light intensity conditions; through the previous evaluation process, the ambient light intensity evaluation value △L can be obtained, which represents the current ambient light intensity. Based on the difference between the ambient light intensity assessment value △L and the preset light intensity assessment value L0, the system selects an appropriate preset initial brightness value ki as the initial brightness of the outdoor display according to a series of preset difference value intervals L1, L2, L3, and L4: when △L-L0≤L1, the preset initial brightness value k1 is selected; when L1<△L-L0≤L2, the preset initial brightness value k2 is selected; when L2<△L-L0≤L3, the preset initial brightness value k3 is selected; when L3<△L-L0≤L4, the preset initial brightness value k4 is selected. This step intelligently selects an appropriate initial brightness value to control the brightness level of the outdoor display based on the difference between the ambient light intensity assessment value and the preset value. By setting different preset initial brightness values ​​and corresponding light intensity assessment value difference intervals, brightness adjustment decisions can be quickly made according to actual lighting conditions, ensuring that the display can provide the best display effect and user experience under different lighting conditions. This not only improves the adaptability and visibility of the outdoor display, but also brings a more comfortable and high-quality display experience to users.

[0027] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein historical temperature data and historical brightness data of the outdoor display are obtained, and the historical temperature data and historical brightness data are analyzed to determine the influence coefficient of temperature on brightness, including: obtaining historical temperature data and historical brightness data of the outdoor display, and preprocessing the historical temperature data and historical brightness data; using the historical temperature data as an independent variable and the historical brightness data as a dependent variable, and fitting the historical temperature data of the independent variable and the historical brightness data of the dependent variable to obtain a fitting model; solving and calculating the fitting model, and determining the model coefficient in the calculation result as the influence coefficient of temperature on brightness.

[0028] Specifically, the system collects and obtains historical temperature and brightness data for outdoor displays, which records the brightness changes of the displays under different temperature conditions. The system preprocesses the historical temperature and brightness data, including data cleaning, outlier removal, and data smoothing, to ensure data accuracy and reliability. A fitting algorithm is used to establish a relationship model between temperature and brightness, using the historical temperature data as the independent variable and the historical brightness data as the dependent variable. The established fitting model is then solved and calculated to obtain the model coefficients, which reflect the degree of temperature's impact on brightness. The magnitude and sign of the coefficients can be used to determine whether the temperature change has a positive or negative impact on brightness. The model coefficients in the calculation results are determined as the temperature-brightness impact coefficients. These coefficients can quantitatively describe the degree of temperature change's impact on the display's brightness, providing a basis for subsequent intelligent brightness adjustment. This step, through the analysis and modeling of historical data, quantitatively describes the relationship between temperature changes and the brightness of outdoor displays. The established fitting model helps users understand the relationship between temperature and brightness, and by calculating the impact coefficients, intelligently adjusts the display's brightness based on temperature changes. This not only improves the display's intelligence but also provides technical support for the adaptability and performance optimization of outdoor equipment under different environmental conditions.

[0029] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein the fitting model is: S=β0+β1*t+ϵ, Among them, S is the dependent variable, t is the independent variable, β0 is the model intercept, β1 is the model coefficient, and ϵ is the error term.

[0030] In an embodiment of the present application, a method for driving and controlling an outdoor display is provided, wherein the method obtains ambient temperature data of an environment in which the outdoor display is located, analyzes the ambient temperature data, and determines an ambient temperature coefficient of the environment in which the outdoor display is located, including: obtaining ambient temperature data of the environment in which the outdoor display is located, and determining an ambient temperature average value based on the ambient temperature data; obtaining a preset standard ambient temperature average value, calculating the difference between the ambient temperature average value and the standard ambient temperature average value, and evaluating the difference to obtain a third evaluation value; obtaining a preset conversion coefficient, and determining the ambient temperature coefficient of the environment in which the outdoor display is located based on the preset conversion coefficient and the third evaluation value.

[0031] Specifically, the system obtains ambient temperature data for the outdoor display's environment, which is collected or recorded in real time by sensors and other devices. Based on the collected ambient temperature data, the system calculates an average value for the ambient temperature data, which reflects the overall temperature level of the current environment. A pre-set standard ambient temperature average value is obtained, representing the ideal ambient temperature level. The difference between the ambient temperature average value and the standard ambient temperature average value is calculated to obtain an evaluation value, which reflects the degree of temperature deviation in the current environment and is referred to as a third evaluation value. The system then determines the ambient temperature coefficient for the outdoor display's environment based on a pre-set conversion coefficient and the third evaluation value. This step intelligently adjusts the outdoor display's parameter settings based on the ambient temperature data, enabling it to maintain optimal performance and display effects under varying temperature conditions. By calculating the difference between the ambient temperature average value and the standard ambient temperature average value and combining it with a pre-set conversion coefficient to determine the ambient temperature coefficient, the system automatically adjusts the display's parameters based on actual ambient temperature changes, improving the display's adaptability and stability under varying environmental conditions. This not only enhances the display's performance, but also improves the user experience and device reliability.

[0034] Specifically, the influence coefficient and the ambient temperature coefficient are multiplied to obtain a comprehensive influence coefficient. This coefficient comprehensively considers the impact of temperature on brightness and the impact of ambient temperature on parameter adjustment. A correspondence between the preset adjustment coefficient and the comprehensive influence coefficient interval is pre-set, and this relationship can be set according to actual needs and device characteristics. Based on the interval to which the comprehensive influence coefficient belongs, the corresponding preset adjustment coefficient is found within the preset adjustment coefficient-comprehensive influence coefficient interval correspondence relationship to determine the driving adjustment coefficient for the outdoor display brightness. Based on the determined driving adjustment coefficient, the initial brightness of the outdoor display is adjusted to obtain the final outdoor display brightness. Based on the final brightness value, the outdoor display is driven and controlled to ensure that the display brightness meets the requirements of the current environment. This step calculates the comprehensive influence coefficient and determines the final driving adjustment coefficient based on the preset adjustment coefficient-comprehensive influence coefficient interval correspondence, thereby intelligently adjusting the brightness of the outdoor display. This method can dynamically adjust the display brightness based on the comprehensive influencing factors, improving the display effect and user experience. This not only improves the adaptability of the display under different environmental conditions, but also improves energy efficiency and performance, providing users with a better visual experience.
