DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] See also Figure 1-Figure 4As shown, the technical solution provided by the present invention is: an energy-saving lighting management system for intelligently controlled advertising light boxes, including a controller arranged inside the advertising light box, the controller corresponds to the advertising light box, and in practice, a group of controllers are installed inside a group of advertising light boxes, and the controller can be used to control the brightness, power, etc. of the advertising light boxes, the controller is wirelessly connected to a server, and the server is connected to a lighting effect test module, a data acquisition module, an energy efficiency analysis module, an operation monitoring module, a comprehensive control module, and a maintenance terminal; See also Figure 3 and Figure 4 As shown, the lighting effect test module is used to perform a comprehensive test on the lighting effect of the advertising light box corresponding to the controller. The specific test process is as follows: In this embodiment, Figure 3 As shown, the advertising light box is composed of components such as a controller, a light box frame, a light box shell, an LED light source, and a power supply circuit. The light box frame is used to fix the LED light source, the power supply circuit and other components. In the actual working process, the LED light source is preferably connected in parallel, and the light source fixing angle and the light source spacing are kept consistent; The controller measures the illumination distribution of each LED light source in the advertising light box under standard operating conditions. In this embodiment, the measurement process of each LED light source is independent of each other, that is, when any LED light source is tested, the other LED light sources are kept off, and the luminous flux of the LED light source corresponding to the illumination area is measured by the illuminometer; like Figure 4 As shown, the luminous flux of the LED light source corresponding to the illumination area at the center position is measured and recorded as the critical luminous flux of the LED light source, and then the luminous flux of the LED light source corresponding to the illumination area at the edge position is measured and recorded as the edge luminous flux of the LED light source. The standard luminous flux interval corresponding to the advertising light box is set according to the critical luminous flux and edge luminous flux of the LED light source. It can be understood that due to the scattering of light, the LED light source will inevitably form an illumination area that spreads from the center to the surroundings during the light emission process, and the light intensity at the center position is the strongest, and the light intensity at the edge position is the weakest; The light box shell of the advertising light box corresponding to the controller is divided into a promotional surface and a non-promotional surface, wherein the promotional surface is the surface of the light box shell with promotional information such as pictures and texts, and the lighting condition of the non-promotional surface does not affect the promotional effect of the advertising light box corresponding to the controller; The promotional surface of the advertising light box corresponding to the controller is divided into a number of pixel grids of the same specifications, and the pixel grids are marked as promotional pixel grids. The actual luminous flux SGi of each promotional pixel grid is measured by an illuminance meter, where i is the promotional pixel grid serial number, the upper limit of i is n, and the value of n is equal to the number of promotional pixel grids; Compare the actual luminous flux of the advertised pixel grid with the standard luminous flux range; If the actual luminous flux is less than or equal to the edge luminous flux, the publicity pixel grid is marked as an overly dark pixel grid; If the actual luminous flux is greater than the edge luminous flux and less than or equal to the critical luminous flux, the publicity pixel grid is marked as a normal pixel grid; If the actual luminous flux is greater than the critical luminous flux, the publicity pixel grid is marked as an over-bright pixel grid; Among them, the values ​​of the edge luminous flux and the critical luminous flux are both greater than zero, and the edge luminous flux is always less than the critical luminous flux. It can be understood that the area where the illumination area of ​​the LED light source is insufficiently covered appears as an overly dark pixel grid, and the area where the illumination area of ​​the LED light source is concentratedly covered appears as an overly bright pixel grid; The number of various publicity pixel grids corresponding to the advertising light box of the controller is counted to obtain the number of too dark pixels GA, the number of normal pixels ZC and the number of too bright pixels GL. It can be understood that the number of too dark pixels GA+the number of normal pixels ZC+the number of too bright pixels GL=the number of publicity pixel grids n; Calculate the illumination distribution coefficient FB of the advertising light box corresponding to the controller according to the formula. The formula is as follows: ; Among them, SGP is the mean value of actual luminous flux, s1 and s2 are weight coefficients with fixed values, the values ​​of s1 and s2 are both greater than zero, s1 is the light coverage weight, s2 is the light uniformity weight, and the light distribution coefficient is used to reflect the lighting effect of the advertising light box corresponding to the controller. The larger the light distribution coefficient, the better the lighting effect of the advertising light box corresponding to the controller; Compare the illumination distribution coefficient of the advertising light box corresponding to the controller with the illumination distribution threshold; If the illumination distribution coefficient is less than the illumination distribution threshold, it is determined that the lighting effect of the advertising light box corresponding to the controller is poor; If the illumination distribution coefficient is greater than or equal to the illumination distribution threshold, it is determined that the lighting effect of the advertising light box corresponding to the controller is good; The lighting effect testing module sends the lighting effect of the advertising light box corresponding to the controller to the server, and the server synchronizes the lighting effect of the advertising light box corresponding to the controller to the maintenance terminal.

[0021] Furthermore, the maintenance terminal is used to perform functional maintenance on the advertising light box corresponding to the controller, and the functional maintenance content specifically includes: If the lighting effect of the advertising light box corresponding to the controller is good, no additional maintenance is required; If the lighting effect of the advertising light box corresponding to the controller is poor, arrange staff to maintain and adjust the LED light source of the advertising light box corresponding to the controller. In the actual working process, the power of the LED light source in the advertising light box is adjusted through the controller, or the setting number of LED light sources, the distance between the light sources, and the distance between the light source and the light box shell are adjusted to make the brightness of the advertising light box corresponding to the controller uniform. For example, when the light box shell is partially too bright, increase the distance between the LED light sources or increase the distance between the light source and the light box shell.

[0022] As a further solution of the present invention, the data acquisition module is used to obtain the rated power consumption data of the advertising light box corresponding to the controller and send it to the server, and the server sends the rated power consumption data of the advertising light box corresponding to the controller to the energy efficiency analysis module, and the rated power consumption data includes the rated power, publicity area and total luminous flux of the advertising light box corresponding to the controller; Among them, the rated power is the total power of all LED light sources in the advertising light box corresponding to the controller, the publicity area is the total area of ​​the publicity surface corresponding to the advertising light box corresponding to the controller, and the total luminous flux is the total luminous flux of the publicity surface corresponding to the advertising light box corresponding to the controller. The value obtained by adding up the actual luminous flux of each publicity pixel grid in the publicity surface corresponding to the advertising light box corresponding to the controller is the total luminous flux; The energy efficiency analysis module is used to conduct a comprehensive analysis of the lighting energy efficiency of the advertising light box corresponding to the controller. The specific analysis process is as follows: Get the rated power EW, publicity area XS and total luminous flux GT of the advertising light box corresponding to the controller, and calculate the energy efficiency ratio NX and power density WP of the advertising light box corresponding to the controller according to the formula. The formula is as follows: NX=GT / EW; WP=EW / XS; Among them, the energy efficiency ratio is used to reflect the energy conversion efficiency of the advertising light box corresponding to the controller, and the power density is used to reflect the unit power consumption of the advertising light box corresponding to the controller; The lighting energy efficiency value ZN of the advertising light box corresponding to the controller is calculated according to the formula. The specific formula is as follows: ZN=NX×a1+(e / WP)×a2; Among them, e is a natural constant, a1 and a2 are weight coefficients with fixed values, the values ​​of a1 and a2 are both greater than zero, a1 is the energy efficiency weight, and a2 is the power weight; Compare the lighting energy efficiency value of the advertising light box corresponding to the controller with the lighting energy efficiency threshold; If the lighting energy efficiency value is less than or equal to the first lighting energy efficiency threshold, the energy efficiency level of the advertising light box corresponding to the controller is determined to be the first energy efficiency level; If the lighting energy efficiency value is greater than the first lighting energy efficiency threshold and less than or equal to the second lighting energy efficiency threshold, the energy efficiency level of the advertising light box corresponding to the controller is determined to be the second energy efficiency level; If the lighting energy efficiency value is greater than the second lighting energy efficiency threshold, the energy efficiency level of the advertising light box corresponding to the controller is determined to be the third energy efficiency level; The values ​​of the first lighting energy efficiency threshold and the second lighting energy efficiency threshold are both greater than zero, the first lighting energy efficiency threshold is less than the second lighting energy efficiency threshold, the energy consumption utilization rate of the first energy efficiency level is lower than the energy consumption utilization rate of the second energy efficiency level, and the energy consumption utilization rate of the second energy efficiency level is lower than the energy consumption utilization rate of the third energy efficiency level; The energy efficiency analysis module sends the energy efficiency level of the advertising light box corresponding to the controller to the server, and the server sends the energy efficiency level of the advertising light box corresponding to the controller to the comprehensive control module.

[0023] Furthermore, the operation monitoring module is used to obtain the actual operation data and surrounding environment data of the advertising light box corresponding to the controller and send them to the server, and the server sends the actual operation data and surrounding environment data of the advertising light box corresponding to the controller to the comprehensive control module; Among them, the actual operation data includes the real-time voltage, real-time current, real-time power and real-time temperature of the advertising light box corresponding to the controller, and the surrounding environment data includes the historical flow of people and the ambient light intensity around the advertising light box corresponding to the controller. Among them, the historical flow of people is the flow of people in the area around the advertising light box corresponding to the controller in the previous monitoring cycle. In the actual working process, the advertising light box corresponding to the controller is equipped with high-precision sensors of current, voltage, power and other factors, and the real-time temperature is obtained through the temperature sensor. The advertising light box is also equipped with a photosensitive sensor and a radar sensor. The photosensitive sensor is used to obtain the ambient light intensity. In fact, the radar sensor is used to monitor the information around the environment in real time, such as the movement of people, historical flow of people, etc. When the radar sensor detects that someone is passing by, it automatically triggers the response mechanism of the lighting system to adjust the brightness of the lamp or turn on the lighting. By integrating radar sensing technology, the system can accurately perceive the information around the environment, realize micro-power consumption operation of the lamp, and can easily adapt to a variety of lamp types. The accuracy and efficiency of radar sensing enable the lamp to automatically turn off or reduce power in unmanned areas, further improving the energy-saving effect.

[0024] In this embodiment, the comprehensive control module is used to intelligently control the lighting brightness of the advertising light box corresponding to the controller. The intelligent control process is as follows: Obtain the ambient light intensity around the advertising light box corresponding to the controller and compare it with the light intensity threshold; If the ambient light intensity is greater than the light intensity threshold, the controller switches the corresponding advertising light box to the off state through the controller; If the ambient light intensity is less than or equal to the light intensity threshold, the controller obtains the historical flow of people around the corresponding advertising light box and compares it with the flow interval; If the historical human flow belongs to the first human flow interval, the controller switches the corresponding advertising light box to the sensing mode through the controller; If the historical pedestrian flow belongs to the second pedestrian flow interval, the controller switches the corresponding advertising light box to the constant light mode through the controller; Among them, the values ​​of the first human flow interval and the second human flow interval are both greater than zero, and the values ​​of the first human flow interval are both less than the values ​​of the second human flow interval. For example, the first human flow interval is [0, 999], and the second human flow interval is [1000, +∞). When the historical human flow is 998 people, the advertising light box switches to the sensing mode. It should be specifically explained that when the advertising light box corresponding to the controller is in the sensing mode, if there are pedestrians in the surrounding area of ​​the advertising light box corresponding to the controller, the controller controls the advertising light box to emit light normally, that is, the brightness is 100%. If there are no pedestrians in the surrounding area of ​​the advertising light box corresponding to the controller, the controller reduces the brightness of the advertising light box after the advertising light box continues to emit light for a period of time. At this time, the brightness is 60%, until there are pedestrians in the surrounding area again, the advertising light box emits light normally. When the advertising light box corresponding to the controller is in the sensing mode or the constant light mode, the real-time voltage SV, real-time current SI, real-time power SW and real-time temperature ST of the advertising light box corresponding to the controller are obtained, and the operation stability coefficient WD of the advertising light box corresponding to the controller is calculated according to the formula. The specific formula is as follows: WD=(e / |SV-BV|+|SI-BI|+|SW-BW|)×b1+(BT-ST)×b2; Among them, e is a natural constant, b1 and b2 are proportional coefficients with fixed values, and the values ​​of b1 and b2 are both greater than zero; BV is the standard voltage of the advertising light box corresponding to the controller, BI is the standard current of the advertising light box corresponding to the controller, BW is the rated power of the advertising light box corresponding to the controller, BT is the temperature critical value of the advertising light box corresponding to the controller, the standard voltage is the median of the normal voltage range corresponding to the advertising light box corresponding to the controller, and the standard current is the same; Compare the operating stability coefficient of the advertising light box corresponding to the controller with the critical stability coefficient; If the operation stability coefficient of the advertising light box corresponding to the controller is greater than or equal to the critical stability coefficient, it is determined that the operation state of the advertising light box corresponding to the controller is normal; If the operation stability coefficient of the advertising light box corresponding to the controller is less than the critical stability coefficient, the energy efficiency level of the advertising light box corresponding to the controller is obtained; If the energy efficiency level of the advertising light box corresponding to the controller is the first energy efficiency level, the advertising light box corresponding to the controller is switched to the off state, and staff are arranged to perform equipment maintenance; If the energy efficiency level of the advertising light box corresponding to the controller is the second energy efficiency level, the controller adaptively adjusts the light brightness of the advertising light box and performs power compensation or heat dissipation compensation; If the energy efficiency level of the advertising light box corresponding to the controller is the third energy efficiency level, the advertising light box will be compensated for power or heat dissipation only through the controller; Specifically, the light brightness, power and heat dissipation can be achieved by controlling the corresponding components through the controller. For example, heat dissipation can be achieved by controlling the heat dissipation components inside the advertising light box. In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.

If the illumination distribution coefficient is less than the illumination distribution threshold, it is determined that the lighting effect of the advertising light box corresponding to the controller is poor. If the illumination distribution coefficient is greater than or equal to the illumination distribution threshold, it is determined that the lighting effect of the advertising light box corresponding to the controller is good.

[0026] Step S20, obtaining rated power consumption data of the advertising light box corresponding to the controller, and performing a comprehensive analysis on the lighting energy efficiency of the advertising light box corresponding to the controller in combination with the rated power consumption data, to obtain the energy efficiency grade of the advertising light box corresponding to the controller through analysis; In this embodiment, the comprehensive analysis process in step S20 is specifically as follows: Step S21, obtaining the rated power, publicity area and total luminous flux of the advertising light box corresponding to the controller, and calculating the energy efficiency ratio and power density of the advertising light box corresponding to the controller; Step S22, then calculating the lighting energy efficiency value of the advertising light box corresponding to the controller; Step S23, comparing the lighting energy efficiency value of the advertising light box corresponding to the controller with the lighting energy efficiency threshold, and determining whether the energy efficiency level of the advertising light box corresponding to the controller is the first energy efficiency level, the second energy efficiency level or the third energy efficiency level.
