[0034] Figure 2 FIG. 1 is a flow chart of an intelligent road lighting method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:
[0035] Step S201, obtaining first environmental impact data, wherein the first environmental impact data at least includes solar altitude angle data and current illumination data at a current moment;
[0036] Specifically, the first environmental impact data is detected by multiple sensors, such as a light sensor, which is used to measure the light intensity of the current environment. The solar altitude angle data is used to represent the current time information, such as whether the current time is morning, noon or evening.
[0037] Wherein, obtaining the first environmental impact data includes the following steps:
[0038] Step S2011, according to the solar declination calculation formula Determine the solar declination, where δ is the solar declination mentioned above and n is the number of days in the year on the current day; where n is the number of days in the year on the current day, i.e. n is the number of days since January 1 of each year. For example, on January 1, n = 1. 23.44° is the inclination of the ecliptic;
[0039] Step S2012, calculate the local hour angle according to the formula Determine the local hour angle, where H is the local hour angle, t is the local time, λ is the longitude of the lighting device, and e is the time difference correction value; t is the local time in hours;
[0040] Step S2013, determining the solar altitude angle according to the solar altitude angle calculation formula h=arcsin(sinδsinφ+cosδcosφcosH), wherein h is the solar altitude angle, δ is the solar declination, φ is the geographical latitude of the lighting device, and H is the local hour angle;
[0041] Step S2014: determining the first environmental impact data at least according to the solar altitude angle.
[0042] Specifically, the concept of solar altitude angle is introduced, and combined with weather conditions and current illumination, comprehensive judgment can be made to more accurately calculate the time to turn on and off the lights. Combined with geographical location and seasonal changes, the time to turn on and off the lights is calculated by the solar altitude angle to ensure that the changes in natural light are accurately reflected.
[0043] Step S202, obtaining second environmental impact data, wherein the second environmental impact data at least includes a weather condition impact factor and vehicle flow data obtained according to model prediction;
[0044] Specifically, the second environmental impact data is data predicted by the model, and the training data of each model is historical data collected by multiple sensors, such as traffic flow sensors and meteorological sensors. The traffic flow sensor is used to monitor the vehicle flow on the road in real time. The meteorological sensor is used to obtain the current weather conditions, including temperature, humidity, rainfall, etc.
[0045] Wherein, obtaining the second environmental impact data includes the following steps:
[0046] Step S2021, constructing a weather condition model and a traffic flow model;
[0047] Step S2022, inputting the first historical data into the weather condition model to predict the weather condition influencing factor, wherein the first historical data includes: the ambient weather at the historical moment and the historical weather condition influencing factor corresponding to the ambient weather at the historical moment acquired in the first historical time period;
[0048] Step S2023, inputting the second historical data into the above-mentioned traffic flow model to predict the above-mentioned vehicle flow data, wherein the above-mentioned second historical data includes: historical moments and historical vehicle flow data corresponding to the above-mentioned historical moments obtained in the second historical time period;
[0049] Step S2024: determining the second environmental impact data based on the weather condition impact factor and the vehicle flow data.
[0050] Specifically, the integrated light sensor, weather station and vehicle detector collects real-time data on ambient light, weather conditions and traffic flow, providing a basis for intelligent control. By analyzing historical traffic flow data, a traffic flow model is established to predict future traffic flow changes. By analyzing historical weather data, a weather condition model is established to predict future weather changes.
[0051] Since traffic flow and weather change rapidly in real time, if only the data collected by real-time sensors are used to control lighting devices, it will lead to control time lag problems. Therefore, a prediction model is used for prediction, and the predicted data is combined with the real-time collected data to comprehensively control the lighting devices, thereby improving the accuracy and real-time performance of the control.
[0052] Step S203, determining whether the lighting device is turned on according to the first environmental impact data and the second environmental impact data;
[0053] Specifically, the lighting device can be a street lamp, which integrates light sensors, weather stations and vehicle detectors to collect ambient light, weather conditions and traffic flow data in real time, providing a basis for intelligent control.
[0054] The current illumination data includes the current illumination intensity. Determining whether the lighting device is turned on according to the first environmental impact data and the second environmental impact data includes the following steps:
[0055] Step S301, determining a comprehensive influencing factor at least according to the current light intensity and the weather condition influencing factor;
[0056] Wherein, determining the comprehensive influencing factor at least according to the above-mentioned current light intensity and the above-mentioned weather condition influencing factor comprises the following steps:
[0057] Step S3011, obtaining the lighting impact factor formula Among them, I f is the current illumination impact factor, I current is the current light intensity, I min is the preset minimum light intensity threshold; the current illumination influence factor I f The value range is [0,1];
[0058] Step S3012, determining the current illumination influence factor according to the illumination influence factor formula, the current illumination intensity and the minimum illumination intensity threshold;
[0059] Step S3013, obtaining the comprehensive impact calculation formula C = W·I f , where C is the above comprehensive influencing factor, and W is the above weather condition influencing factor;
[0060] Step S3014, determining the comprehensive impact factor according to the comprehensive impact calculation formula, the weather condition impact factor and the current illumination impact factor.
[0061] Specifically, the influencing factors of weather conditions and current illumination are introduced to dynamically adjust the light on / off time to improve the adaptability and flexibility of the system. A weather condition influencing factor W is set with a value range of [0,1], 1 for sunny days, 0.7 for cloudy days, 0.5 for rainy days, and 0.3 for foggy days. That is, the value of the weather condition influencing factor corresponds to the actual weather conditions.
[0062] Step S302, when the solar altitude angle data is less than or equal to a first altitude threshold, and the comprehensive influencing factor is greater than or equal to a first value, determining that the lighting device is turned on;
[0063] Step S303, when the solar altitude angle data is greater than the second altitude threshold, and / or the comprehensive influencing factor is less than the second value, determine that the lighting device is turned off, the first altitude threshold is less than the second altitude threshold, and the first value is greater than the second value.
[0064] Specifically, the method for calculating the switching time of lights based on comprehensive analysis of multiple factors integrates data from light sensors, meteorological stations and vehicle detectors, combines the influencing factors of solar altitude angle and weather conditions, and dynamically calculates the switching time of street lights to ensure precise control under different environmental conditions.
[0065] The first height threshold can be set to -6°, the first value can be set to 0.5, the second height threshold can be set to 0°, and the second value can be set to 0.2. That is, when the sun altitude angle h is lower than a certain threshold (for example, -6° represents civil dusk / dawn), and the comprehensive impact factor C is greater than a certain threshold (for example, 0.5), the street light is turned on; when the sun altitude angle h is higher than a certain threshold (for example, 0° represents complete darkness), or the comprehensive impact factor C is less than a certain threshold (for example, 0.2), the street light is turned off.
[0066] Step S204: when the lighting device is turned on, determine the current brightness of the lighting device at least according to the first environmental impact data and the second environmental impact data.
[0067] Specifically, based on light intensity, traffic flow and weather conditions, the brightness of street lights is dynamically adjusted through an optimization formula to achieve the dual goals of energy saving and safety.
[0068] The current illumination data includes the current illumination intensity, the vehicle flow data includes the predicted current traffic flow, and the current brightness of the lighting device is determined at least based on the first environmental impact data and the second environmental impact data, including the following steps:
[0069] Step S2041, obtaining a brightness adjustment formula Wherein, L is the current brightness of the above lighting device, L max is the maximum brightness of the above lighting device, I current is the current light intensity, I min is the preset minimum light intensity threshold, F is the predicted current traffic flow, and F max is the maximum traffic flow of the road section where the lighting device is located at the target time in the historical data, W is the weather condition influencing factor, the target time is the time of the day in the historical data that is the same as the current time, α, β and γ are the first weight coefficient, the second weight coefficient and the third weight coefficient, respectively, α+β+γ=1;
[0070] Step S2042: determining the current brightness of the lighting device according to the brightness adjustment formula.
[0071] Specifically, a dynamic brightness adjustment formula that takes into account light intensity, traffic flow and weather conditions can be introduced to more accurately adjust the brightness of street lamps. Among them, W is the weather condition influencing factor (1 for sunny days, 0.7 for cloudy days, 0.5 for rainy days, and 0.3 for foggy days). The weight coefficient can be optimized through machine learning based on historical data to ensure the best lighting effect and energy saving effect under different conditions.
[0072] Wherein, after determining the current brightness of the lighting device at least according to the first environmental impact data and the second environmental impact data, the method further comprises the following steps:
[0073] Step S401, determining the daily on-time of the lighting device as the actual working time;
[0074] Step S402, obtaining the energy saving formula E=P·(t fixed -t actual ), where E is the daily energy saving of the lighting device, P is the power of a single lighting device, t fixed is the working time of the above lighting device under a fixed schedule, t actual The actual working time of the above lighting device;
[0075] Step S403: determining the daily energy saving amount of the lighting device according to the energy saving formula.
[0076] Specifically, the combined effects of light intensity, traffic flow and weather conditions are utilized to dynamically adjust the brightness of street lamps through an optimized mathematical formula to achieve the dual goals of energy saving and safety.
[0077] The intelligent lighting method for the above-mentioned road of the present application first obtains the first environmental impact data, which at least includes the solar altitude angle data and the current illumination data at the current moment; then obtains the second environmental impact data, which at least includes the weather condition influencing factors and vehicle flow data predicted by the model; then determines whether the lighting device is turned on based on the first environmental impact data and the second environmental impact data; finally, when the lighting device is turned on, determines the current brightness of the lighting device based on at least the first environmental impact data and the second environmental impact data. The method integrates GPS, light sensors, meteorological stations, vehicle detectors and other equipment to collect and analyze ambient light, weather conditions and traffic flow data in real time, dynamically adjust the switching time and brightness of street lamps, thereby achieving energy conservation and emission reduction and improving road safety, and solves the problem that the lighting system in the prior art only considers a single factor and does not make full use of multiple sensor data for comprehensive analysis, resulting in poor lighting effects or low energy efficiency.
[0078] In some examples, the above method is applied to an intelligent road lighting control system based on multiple factors (including traffic flow, lighting, weather conditions, current time zone, etc.). The system monitors these factors in real time and uses dynamic algorithms to intelligently adjust the timing of turning on and off street lights and the brightness, thereby achieving the dual goals of energy saving and ensuring traffic safety.
[0079] The core of the system includes: traffic flow analysis module, light intensity measurement module, weather condition analysis module, time zone judgment module and intelligent control unit.
