Description

Background Art

[0002] According to some environmental lighting requirements, for example, the illumination requirement for underground garages in residential buildings is 30lx, and the ground illumination requirement for public garages in general rooms and places is 50lx; the low, medium and high illumination standards for lane locations are 30lx, 50lx and 70lx respectively; the low, medium and high illumination standards for parking spaces are 20lx, 30lx and 50lx respectively. At the same time, the ground illumination standard for garages with civil air defense properties is 50lx.

[0003] In the related art, lighting control only relies on fixed thresholds, without considering the nonlinear relationship between temperature and humidity coupling and luminous flux attenuation. For example, high humidity will aggravate the impact of temperature on the performance of LED chips, but the related art cannot analyze the impact of temperature and humidity on lighting, resulting in the inability to meet lighting needs. In a distributed lighting system, the independent operation of multiple terminals can easily lead to overlapping areas being too bright and edge areas being too dark, making it difficult to meet lighting requirements. Summary of the invention

[0009] It should be further explained that the main control module obtains the distance between the illuminated position and each lighting terminal respectively, and calculates the total illumination intensity E of the illuminated position illuminated by multiple lighting terminals in combination with the luminous intensity of the lighting terminal and the angle between the lighting terminal and the illuminated position. PB1 ; When any lighting terminal is not turned on and the preset light intensity E is required target When the main control module obtains the light intensity E of the turned-on lighting terminal based on the following calculation method PB1 ,

[0010] I B1 is the luminous intensity of the unlit terminal, α PB1 is the angle between the unlit lighting terminal and the illuminated position, r PB1 It is the distance between the illuminated location and the unlit terminal.

[0011] It should be further explained that the main control module also controls the luminous intensity based on the following method: , where I is the light intensity of the light emitted by the lighting terminal after passing through a preset distance L, I0 is the initial light intensity, and β is the attenuation coefficient.

[0012] It should be further explained that the lighting terminal is provided with an ultrasonic distance sensor; The main control module is connected to the ultrasonic distance sensor to obtain the distance information r between the lighting terminals based on the following method: AB11 ,

[0013] Among them, t AB11 It indicates the time from when the sound wave is emitted from the lighting terminal to when the tested lighting terminal receives the ultrasonic wave.

[0014] It should be further explained that the detection control component also includes: a storage module and a communication module; the lighting terminal is also provided with a terminal communication module; The main control module is connected through communication with the terminal communication module, the storage module and the communication module.

[0015] It should be further explained that the detection and control component also includes: an infrared acquisition module and an audio acquisition module; The main control module detects the sounds of pedestrians and vehicles by communicating with the audio acquisition module. If no sound is detected, the infrared acquisition module detects the infrared signals of pedestrians or vehicles. If the infrared signal of pedestrians or vehicles is detected, the lighting terminal is controlled to turn on; If no infrared signal of a pedestrian or vehicle is detected, the lighting terminal remains turned off.

[0016] The present application also provides a distributed intelligent lighting control method, the method comprising: The temperature, humidity and light intensity information obtained are used to calculate the total light attenuation correction factor under the combined effects of temperature and humidity based on the preset environmental impact control algorithm and combined with the light intensity attenuation and refractive index algorithm, and determine whether the total light attenuation correction factor is less than the compensation light attenuation parameter; If it is greater than, the current light intensity is recorded as the initial parameter; If it is less than, the current light intensity parameter of the lighting terminal will be maintained.

Through the above workflow, the system of this embodiment can adjust the brightness of the lighting terminal in real time according to the changes in environmental parameters to realize the lighting control function.

[0022] The distributed intelligent lighting control system provided by this application integrates the main control module, temperature and humidity sensors and light sensors to collect environmental parameters in real time, and dynamically calculates the total light attenuation correction factor under the combined effects of temperature and humidity by combining the environmental impact control algorithm and the light intensity attenuation model. When the correction factor exceeds the preset compensation threshold, the system automatically records the current light intensity as the reference value, and accurately controls the output power of the lighting terminal by comparing the light intensity attenuation before and after the temperature and humidity changes, so as to maintain a stable lighting effect in scenes such as underground garages, and realize environmentally adaptive intelligent light control management.

[0023] The system uses algorithms to determine the quantitative impact of temperature and humidity on light intensity attenuation, and records initial parameters to provide a benchmark value for judging light intensity changes. It can compare the current light intensity with the light intensity after considering the influence of temperature and humidity, and clearly present the changes in light intensity. It provides accurate initial data for the lighting control system, and can adjust the brightness of the lighting terminal in real time according to environmental changes to meet the lighting needs of various scenes such as underground garages and production workshops.

[0024] The communication method between the main control module mentioned in this application and each lighting terminal can be wired or wireless communication. In this embodiment, a communication module can be set, which can specifically include a GE wired module and a 4G wireless module, providing a flexible communication method for the system. The GE wired module has a gigabit transmission rate, fast and stable data transmission, and is suitable for scenarios with high requirements for data transmission, but it requires the deployment of a wired network, which may be restricted in some complex sites. The 4G wireless module can meet the sending and uploading of conventional data volumes, and is easy to deploy without complex wiring work. It is suitable for some sites where it is difficult to deploy a wired network. Users can flexibly choose which network module to use based on the actual deployment site.

[0026] The lighting terminal may be an LED lighting terminal. When describing the system of the present application below, the LED lighting terminal is taken as an example.

The software code can be implemented by a software application (or program) written in any appropriate programming language, and the software code can be stored in a memory and executed by a controller.

[0028] The specific contents of the distributed intelligent lighting control system will be described in detail below. For the purpose of explanation rather than limitation, specific details such as specific system structures and technologies are proposed to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application can also be implemented in other embodiments without these specific details.

[0029] It should be understood that the "one or more" mentioned in this application refers to one, two or more than two, and the "multiple" mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B. The "and / or" in this article is just a way to describe the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit the difference.

[0031] The phrases such as "one embodiment" or "some embodiments" described in the present application mean that the specific features, structures or characteristics described in the embodiment are included in one or more embodiments of the present application. Therefore, the phrases such as "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments" etc. that appear in different places in the present application do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0033] See also Figure 1 and Figure 2 As shown, the distributed intelligent lighting control system provided in this embodiment includes: a detection control component and a lighting terminal.

[0034] The detection and control components include: a main control module, a temperature sensor, a humidity sensor, a light sensor, an infrared acquisition module, an audio acquisition module, a storage module and a communication module.

[0035] Optionally, in order to meet the monitoring requirements, an intelligent lighting management platform can be set up, which can communicate with the main control module to obtain the operation information of the lighting terminal, environmental information, illuminance information, etc., and can meet the user's usage requirements by displaying the information. It can also remotely control the operation of each lighting terminal, adjust the illuminance, and control the switch of the lighting terminal, etc.

[0036] The communication module of this embodiment can adopt a GE wired module and a 4G wireless module.

[0037] In some embodiments, the main control module is bidirectionally connected to the storage module, GE wired module, 4G wireless module and BT module respectively, and the main control module can interact and transmit data with these modules. The GE wired module and the 4G wireless module serve as dual backup network modules, providing the system with two ways to communicate with the intelligent lighting management platform, either through the Gigabit wired network or the 4G wireless network. When one network fails, the other network can continue to ensure normal communication of the system. The main control module is connected to the lighting terminal to control the operation of the lighting terminal; and the temperature sensor, humidity sensor, light sensor, infrared acquisition module, and audio acquisition module are respectively connected to the main control module, and the collected environmental parameters can be transmitted to the main control module.

[0038] The main control module receives information such as temperature, humidity, sound, infrared, and light intensity collected by various sensors, and performs parameter calculation and threshold judgment on the received information. For example, when the temperature is too high or too low, it may affect the luminous efficiency of the lighting terminal. The main control module determines the degree of influence of such environmental parameters on the brightness of the lighting terminal through calculation and judgment, and then adjusts the lighting terminal to the most appropriate brightness under specific conditions. This can not only ensure the lighting effect, but also avoid energy waste and achieve energy-saving control.

[0039] The storage module of this embodiment stores system software to ensure the normal operation of the system; it can also store the location information of the lighting terminal to facilitate the management and control of each lighting terminal. It stores the default configuration information issued by the intelligent lighting management platform through the network module, which can be used as the initial parameters for system operation; it also stores the data collected by each sensor, which can be used for subsequent data analysis and system optimization.

[0040] This embodiment also has a BT module for implementing the transmission of environmental parameters between lighting terminals. Through the BT module, each lighting terminal can share the environmental parameters collected by each other, thereby achieving parameter synchronization.

[0041] As an embodiment of the present application, the audio acquisition module in the detection control component starts working, continuously collects sound information in the surrounding environment, and transmits this information to the main control module. The main control module analyzes the sound data provided by the audio acquisition module to determine whether there are sounds made by pedestrians and vehicles.

[0042] When the main control module determines through analysis that no pedestrian or vehicle sounds are detected, the infrared acquisition module will be activated. The infrared acquisition module begins to search for infrared signals emitted by pedestrians or vehicles within its monitoring range and feeds the collected signals back to the main control module. After receiving the feedback signal from the infrared acquisition module, if the main control module determines that there is an infrared signal from a pedestrian or vehicle, it will immediately send an opening command to the lighting terminal to control the lighting terminal to turn on and provide lighting for pedestrians or vehicles.

[0043] If the main control module determines that the infrared acquisition module has not detected the infrared signal of pedestrians or vehicles, it will maintain the lighting terminal in the off state and will not turn it on. The entire detection process is not a one-time process, but a continuous cycle. The audio acquisition module and the infrared acquisition module will continuously collect sound and infrared signals, and the main control module will also continuously analyze these data and adjust the on / off state of the lighting terminal in real time according to the detection results of sound and infrared signals.

[0044] In this way, the system controls the switch of the lighting terminal through the dual detection of sound and infrared signals. When there are no pedestrians or vehicles, the lighting terminal is in the off state, and it is only turned on when pedestrians or vehicles are detected, avoiding unnecessary opening of lighting equipment and long-term lighting, thereby reducing energy consumption and achieving the purpose of energy saving.

[0045] In a working process of this embodiment, environmental parameters can be collected in real time based on temperature sensors, humidity sensors, infrared sensors, and light sensors, and transmitted to the main control module.

[0046] After receiving the data collected by the sensor, the main control module of this embodiment calculates the parameters of the data and distinguishes the corresponding thresholds to determine the impact of various environmental parameters on the brightness of the lighting terminal to be turned on. According to the calculation and judgment results, the brightness of the lighting terminal is adjusted to achieve the best lighting effect and energy saving. Through the above workflow, the system of this embodiment can adjust the brightness of the lighting terminal in real time according to the changes in environmental parameters to achieve the lighting control function.

[0047] In this embodiment, multiple lighting terminals can be configured according to actual usage environment requirements and deployed in a matrix form.

[0048] As an example, multiple LED lighting terminals are deployed in a matrix form in an underground garage scene, and the LED lighting terminals in each area can be independently adjusted by the detection and control components. According to the system's preset environmental impact control algorithm, when the humidity in a certain area in the garage rises, the LED lighting terminal corresponding to the area can automatically adjust the light intensity based on the calculated total light decay correction factor to ensure that the driver is always in a clear and bright visual environment. For the production workshop, using this system, after the LED lighting terminals in each area form a matrix, the brightness can be accurately adjusted according to the temperature, humidity and light intensity changes in the area where they are located. For example, in a high-temperature equipment operation area, the LED lighting terminal can compensate for the light intensity attenuation according to the algorithm to ensure the safety of workers' operations. At the same time, through matrix deployment, regional energy-saving control can be achieved, avoiding energy waste caused by unified lighting in the entire workshop, improving energy utilization, and adapting to the complex and changeable lighting needs of the production workshop. In some specific embodiments, such as Figure 3 As shown, in the case where multiple LED lighting terminals are deployed in a matrix form, the LED lighting terminals are affected by the front, rear, left and right adjacent LED lighting terminals in the matrix deployment. For example, the LED lighting terminals are arranged in a matrix of A0~An in the horizontal direction and A0~Z0 in the vertical direction. The position of LED lighting terminal B1 is between four LED lighting terminals A1, C1, B0 and B2. The position distance information between the LED lighting terminal B1 and the ground position point PB1 is r respectively. AB11 、r BC11 、r BB01 、r BB12 According to the following calculation formula of light intensity and distance, the light intensity required by LED lighting terminal B1 itself is closely related to the light intensity and spacing distance of LED lighting terminals A1, C1, B0, and B2.

[0049] A specific implementation method is given below: deploy multiple LED lighting terminals in a matrix form with A0-An in the horizontal direction and A0-Z0 in the vertical direction. For each LED lighting terminal, record its position in the matrix and the distance information from the adjacent LED lighting terminals in front, behind, left, and right directions to the ground position point. For example, for LED lighting terminal B1, record its distance r from A1, C1, B0, B2 to the ground position point PB1 in the vertical direction. AB11 、r BC11 、r BB01 、r BB12 .

[0050] Get the luminous intensity I of the adjacent LED lighting terminal A1, LED lighting terminal C1, LED lighting terminal B0, and LED lighting terminal B2 A1 ,I C1 ,I B0 ,I B2. Measure the angle α between the adjacent LED lighting terminal and the PB1 position point AB11 , α BC11 , α BB01 , α BB12 It corresponds to the angle between the four lighting terminals and the illuminated position point.

[0051] According to the calculation formula of light intensity and distance, calculate the light intensity E,

[0052] Among them, E is the calculated light intensity, in lux (lx); I is the luminous intensity of the light source in the lighting direction, in candela (cd); α is the angle between the normal direction of the illuminated surface and the lighting direction; r is the distance from the light source to the illuminated point, in meters (m). It can be seen from the light intensity that the light intensity is proportional to the luminous intensity of the light source, inversely proportional to the square of the distance, and proportional to the cosine value of the illumination angle.

[0053] Since the total illumination intensity of the four LED lighting terminals A1, C1, B0, and B2 is the vector sum of the illumination intensities generated by the four LED lighting terminals at PB1, it is known that the distances from the four LED lighting terminals to PB1 are r AB11 、r BC11 、r BB01 、r BB12 , and their luminous intensities are I A1 ,I C1 ,I B0 ,I B2 , and P B1 The angles of the position points are α AB11 , α BC11 , α BB01 , α BB12 , we can get the total illumination intensity EPB1 of the surrounding LED lighting terminals at the PB1 location, as shown in the following formula:

[0054] Therefore, it can be concluded that the light intensity at the PB1 position has reached the light intensity of EPB1 when the LED lighting terminal B1 is not turned on. If the light intensity at the PB1 position is to reach Etarget, the light intensity that the LED lighting terminal B1 needs to provide is:

[0055] Therefore, the luminous intensity IB1 that the LED lighting terminal B1 needs to provide in the vertical direction can be obtained as follows:

[0056] Among them, r PB1is the vertical distance between the LED lighting terminal B1 and the position point PB1, that is, .

[0057] According to the calculated I B1 , adjust the luminous intensity of LED lighting terminal B1 so that the light intensity at point PB1 reaches the target value E target .

[0058] As an example of the present application, the main control module can also control the luminous intensity of the lighting terminal based on the following method: , where I is the light intensity of the light emitted by the lighting terminal after passing through a preset distance L, I0 is the initial light intensity, and β is the attenuation coefficient.

[0059] In some specific embodiments, taking the optimization of the lighting of the underground garage lane as an example, high brightness (≥200lx) is required to prevent glare when vehicles enter and exit, and it is automatically reduced to 50lx when no one is there. The lane width is 8 meters, and the LED matrix is ​​spaced 5 meters horizontally, that is, A0~A4 involved in this embodiment, and 3 meters vertically, that is, B0~B2 involved in this embodiment.

[0060] When a vehicle enters, the ultrasonic sensor detects movement, triggering terminals B1, B2, etc. to re-measure the distance. For example, B1 measures the horizontal distance r to C1 on the right. BC11 =4.2 m, angle of incidence α BC11 =30°. Assuming that the luminous intensity of C1 IC1 = 800cd, B1 itself needs to compensate for the illumination: .

[0061] Set EPB1 to the total illumination intensity (unit: lx) at the target point PB1, which is the sum of the illumination intensities of the four adjacent terminals. EA1, EC1, EB0, EB2: the illumination intensities of the four adjacent terminals on PB1 respectively. Based on ΔE=E target −E PB1 , the additional light intensity required at position B1 can be calculated.

[0062] The contribution of each adjacent terminal to the light intensity of PB1 is calculated by the following formula: .

[0063] Among them, I X is the luminous intensity, α X is the angle between the illumination direction of the lighting terminal and the normal of the illuminated surface at PB1, r X is the horizontal distance from the lighting terminal to PB1.

[0064] Combined with the above methods, multiple light source angles are controlled to prevent single-point strong light from directly hitting the driver's eyes. Automatically dim to 50lx when no one is around.

[0065] The following is an embodiment of a distributed intelligent lighting control method provided by an embodiment of the present disclosure. This method and the distributed intelligent lighting control systems of the above-mentioned embodiments belong to the same inventive concept. For details not described in detail in the embodiments of the distributed intelligent lighting control method, reference can be made to the embodiments of the above-mentioned distributed intelligent lighting control system.

[0066] The method includes: obtaining temperature, humidity and light intensity information, calculating the total light attenuation correction factor under the combined effects of temperature and humidity based on a preset environmental impact control algorithm and combining the light intensity attenuation and refractive index algorithm, and determining whether the total light attenuation correction factor is less than the compensation light attenuation parameter.

[0067] If it is greater than, the current light intensity is recorded as the initial parameter; when the total light decay correction factor γ is greater than the compensation light decay parameter, after recording the current light intensity as the initial parameter, the system will determine the amount of light decay that needs to be compensated based on the calculated total light decay correction factor γ and the initial light intensity. Then, the system will send instructions to the lighting terminal through the main control module to adjust the output power of the lighting terminal to increase the light intensity, compensate for the light decay caused by changes in temperature and humidity, and make the lighting brightness reach a suitable level to meet the lighting needs of the corresponding scene. In addition, the system may continue to monitor changes in temperature, humidity and light intensity, continuously update the total light decay correction factor γ, and dynamically adjust the brightness of the lighting terminal according to the new calculation results to maintain the stability of the lighting effect.

[0068] If it is less than, the current light intensity parameter of the lighting terminal is maintained. When the total light decay correction factor γ is less than the compensation light decay parameter, after maintaining the current light intensity parameter of the lighting terminal, the system will continue to monitor environmental parameters such as temperature, humidity and light intensity in real time. Because environmental factors are constantly changing, although light decay compensation is not required under the current temperature and humidity conditions, subsequent environmental parameters may change, causing the total light decay correction factor γ to be greater than the compensation light decay parameter, and light decay compensation is required. At the same time, the system will also record these environmental parameters and the corresponding lighting status information for analysis and optimization of the performance of the lighting control system, such as further improving the preset environmental impact control algorithm so that it can more accurately adapt to lighting needs under different environmental conditions.

[0069] In this embodiment, by presetting the environmental impact control algorithm and combining the light intensity attenuation and refractive index algorithm, the parameter can be calculated to clarify the specific quantitative impact of temperature and humidity on light intensity attenuation.

[0070] The purpose of recording the current light intensity as the initial parameter in this embodiment is to provide a reference value for subsequent judgment of the impact of temperature and humidity on light intensity. γThat is, after obtaining the influencing factors, the current light intensity can be compared with the light intensity after considering the influence of temperature and humidity, so as to understand the specific changes in light intensity caused by changes in temperature and humidity. It can also provide accurate initial data for the lighting control system so that the brightness of the lighting terminal can be adjusted in real time according to environmental changes. If temperature and humidity have an impact on light intensity, the system can control the output power of the lighting terminal based on the initial parameters and the calculated influencing factors to keep the lighting brightness at an appropriate level to meet the lighting needs of scenes such as underground garages.

[0071] In this method, the total light attenuation correction factor under the combined effects of temperature and humidity is calculated based on the light intensity attenuation and refractive index algorithm. γ The method is: γ =1+( α T ×Δ T )+( α H ×Δ RH ); in, α T γ is the percentage of luminous flux attenuation caused by unit temperature change; αH is the percentage of luminous flux attenuation caused by unit relative humidity change; ΔT is the temperature change, and ΔRH is the humidity change. γ>1: light attenuation compensation is required; γ≤1: no compensation is required.

[0072] Furthermore, as a refinement and extension of the specific implementation methods of the above embodiment, in order to fully illustrate the specific implementation process in this embodiment, a specific execution method is provided below.

[0073] Methods include: Step 101: The temperature sensor and humidity sensor collect parameters of the external environment, and upload the acquired parameters to the main control module, and calculate the influence of temperature and humidity on the current air refractive index through the Ciddor formula; according to the heat dissipation and absorption theory, the light intensity follows the Beer-Lambert law when propagating in the medium, that is. Then, the light intensity after a certain distance is calculated through the relationship formula between light intensity attenuation and refractive index.

[0074] Step 102: Determine the specific impact of the current temperature and humidity parameters on light attenuation. If there is an impact, calculate the total light attenuation correction factor γ of temperature and humidity on light intensity, and record the current light intensity as the initial parameter; if there is no impact, use the default configuration parameters as the current light intensity parameters.

[0075] As an implementation of the method of the present application, an audio acquisition module is provided. When the matrix distributed LED lighting terminals are deployed, the distance between adjacent lighting terminals is calculated by the audio acquisition module in combination with the BT module and the main control module.

[0076] For example, LED lighting terminal B1 sends sound waves from four LED lighting terminals, namely, LED lighting terminal A1, LED lighting terminal C1, LED lighting terminal B0, and LED lighting terminal B2, and starts timing synchronously. The LED lighting terminal B1 is synchronized through the BT module. After receiving the sound waves from different LED lighting terminals around it, the distance from LED lighting terminal A1 is calculated by the following calculation formula. Other distances can be obtained similarly.

[0077] Among them, t AB11 It indicates the time from when the sound wave is emitted from the lighting terminal to when the tested lighting terminal receives the ultrasonic wave.

[0078] The above data is only calculated and recorded in the storage module when the distributed intelligent lighting terminal is deployed.

[0079] This embodiment takes into account the correlation between the illumination intensity and the distance from the light source to the illuminated point. By accurately calculating the distance between adjacent illumination terminals, the main control module can consider more accurate distance parameters when calculating the illumination intensity at a certain location, thereby adjusting the luminous intensity of each illumination terminal to make the illumination of the entire illumination area more uniform.

[0080] In some places with high lighting requirements, such as laboratories, if the distance between lighting terminals is not appropriate, problems such as light overlap or shadows may occur. Through accurate distance calculation, the position and angle of the lighting terminal can be reasonably adjusted to reduce light interference and ensure the lighting effect.

[0081] In conjunction with the above-mentioned distributed intelligent lighting control system, the present application also provides an electronic device, including a memory, a processor, and a computer program stored on the memory and executable on the processor, wherein the processor implements the distributed intelligent lighting control system when executing the program. The electronic device may be a detection control component. The electronic device includes, but is not limited to, a laptop computer, a desktop computer, a workbench, a personal digital assistant, a server, a blade server, a mainframe computer, and other suitable computers.
