Description

Technical Field

[0001] This application relates to the field of intelligent building lighting control technology, and in particular to an indoor sunlight simulation method, system, device, and medium. Background Technology

[0002] With the development of smart buildings and healthy lighting, dynamic lighting systems that simulate natural light are becoming increasingly popular. Existing dynamic lighting solutions, such as the "Human-Centric Lighting (HCL)" function in the KNX system, can pre-program changes in light color temperature and brightness based on sunrise and sunset times calculated from fixed clock times or geographical coordinates. However, this absolute time-based control method has significant shortcomings: it cannot sense and respond to instantaneous changes in actual weather (e.g., delayed dawn on a rainy day, or a sudden change from clear to overcast skies), causing a disconnect between the indoor lighting environment and the actual outdoor daylight conditions, thus reducing the realism of the simulation. Summary of the Invention

[0003] This application provides an indoor sunlight simulation method, system, device, and medium to solve the problem that existing indoor sunlight simulation schemes cannot sense and respond to instantaneous changes in actual weather, resulting in a disconnect between the indoor light environment and the actual outdoor skylight conditions, thus reducing the realism of the simulation.

[0004] The first aspect of this application provides an indoor sunlight simulation method. The method includes: acquiring real-time outdoor illuminance information, wherein the real-time illuminance information is the illuminance information at the current outdoor moment; determining the rate of change of illuminance within a preset number of time periods based on illuminance information at preset time periods; determining the current outdoor solar radiation trend based on the rate of change of illuminance and a preset trend threshold; and adjusting the indoor lighting mode according to the solar radiation trend. In some embodiments of this application, before acquiring the real-time outdoor illuminance information, the method further includes: monitoring environmental information of an indoor target area, wherein the environmental information is used to trigger a pre-trained target detection model to identify target information, and acquiring the real-time outdoor illuminance information when the target information includes a person.

[0005] In some embodiments of this application, determining the rate of change of illuminance within the preset number of time periods based on illuminance information at preset time periods includes: establishing a time queue with a preset number of capacity, and updating the time queue based on the illuminance information at the current time period to obtain the illuminance information at the preset number of time periods.

[0006] In some embodiments of this application, the illuminance information at a preset number of times includes: the illuminance information at the current time and the illuminance information at multiple historical times, and the step of determining the rate of change of illuminance within the preset number of times based on the illuminance information at the preset number of times includes: determining the rate of change of illuminance within the preset number of times based on the illuminance information at the current time, the illuminance information of the historical time that first entered the time queue, and the preset number of times.

[0007] In some embodiments of this application, the trend threshold includes a first trend threshold, a second trend threshold, and a third trend threshold. Determining the current outdoor sunshine trend based on the rate of change of illuminance and the preset trend threshold includes: within a first preset time period, if the rate of change of illuminance is greater than the first trend threshold, the sunshine trend is a sunrise trend, wherein the first trend threshold is a trend threshold corresponding to the sunrise trend; and within a second preset time period, if the rate of change of illuminance is less than the second trend threshold, the sunshine trend is a sunset trend, wherein the second trend threshold is a trend threshold corresponding to the sunset trend; and within a third preset time period, if the rate of change of illuminance is less than the third trend threshold, the sunshine trend is a stable midday sunshine trend, wherein the third trend threshold is a trend threshold corresponding to the stable midday sunshine trend.

[0008] In some embodiments of this application, adjusting the indoor lighting mode according to the sunshine trend includes: when the sunshine trend is the sunrise trend, the lighting mode is the morning light mode; and when the sunshine trend is the sunset trend, the lighting mode is the sunset mode; and when the sunshine trend is the stable lighting trend, the lighting mode is the stable midday sunshine trend.

[0009] A second aspect of this application provides an indoor sunlight simulation system, comprising: a light acquisition module for acquiring real-time outdoor illuminance information, wherein the real-time illuminance information is the outdoor illuminance information at the current moment; an intelligent control module for determining the rate of change of illuminance within a preset number of time periods based on illuminance information at preset time periods; and determining the current outdoor solar radiation trend based on the rate of change of illuminance and a preset trend threshold; and a light adjustment module for adjusting the indoor light mode according to the solar radiation trend.

[0010] In some embodiments of this application, the light acquisition module includes a first sensor installed outdoors for acquiring outdoor illuminance information; the system also includes a second sensor installed indoors for monitoring environmental information of the indoor target area, the environmental information being used to trigger a pre-trained target detection model to identify target information, and acquiring real-time outdoor illuminance information when the target information includes a person; the light adjustment module includes an LED light installed indoors, and adjusts the brightness and color temperature of the LED light within a preset time period to adjust the indoor lighting mode to the target mode.

[0011] A third aspect of this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method described in any of the first aspects of the above embodiments.

[0012] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the method described in any of the first aspects of the above embodiments.

[0013] This application has the following beneficial effects: By acquiring real-time outdoor illuminance information and calculating the rate of change of illuminance within a preset time, and combining it with a preset trend threshold, this application accurately determines the current outdoor solar trend (such as sunrise, sunset or sudden weather changes), and then dynamically adjusts the indoor lighting mode. This overcomes the shortcomings of existing technologies that rely solely on fixed times to achieve lighting simulation and cannot perceive real-time weather changes, and realizes real-time synchronization and realistic simulation of the indoor lighting environment with the outdoor natural skylight state.

Detailed Implementation

[0016] In the following description, specific details such as particular system architectures, interfaces, and technologies are presented for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of this application.

[0017] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Furthermore, "many" in this document means two or more. Moreover, the term "at least one" in this document means any combination of at least two of any one or more of a plurality of objects. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0018] As described in the background section, existing indoor sunlight simulation solutions cannot sense and respond to instantaneous changes in actual weather, resulting in a disconnect between the indoor lighting environment and the actual outdoor skylight conditions, thus reducing the realism of the simulation.

[0019] To address the aforementioned issues, this application proposes a simulation method that does not rely on an absolute timetable but instead intelligently identifies natural light state transition points such as sunrise and sunset based on the real-time trend of outdoor illuminance changes. This method enables indoor light simulation to closely reflect actual weather changes, improving real-time response and environmental immersion.

[0020] This application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] According to one embodiment of this application, this application proposes an indoor sunlight simulation method, such as... Figure 1 As shown, the method of this application includes the following steps S1-S4: S1, obtaining real-time outdoor illuminance information, where real-time illuminance information is the illuminance information at the current outdoor moment; S2, determining the rate of change of illuminance within a preset number of time periods based on the illuminance information at preset time periods; S3, determining the current outdoor solar radiation trend based on the rate of change of illuminance and a preset trend threshold; S4, adjusting the indoor lighting mode based on the solar radiation trend.

[0022] Therefore, this application obtains real-time outdoor illuminance information and calculates the rate of change of illuminance within a preset time. It then combines the preset trend threshold to accurately determine the current outdoor solar trend (such as sunrise, sunset, or sudden weather changes), and dynamically adjusts the indoor lighting mode. This overcomes the shortcomings of existing technologies that rely solely on fixed times to simulate lighting and cannot perceive real-time weather changes. It achieves real-time synchronization and realistic simulation of the indoor lighting environment with the outdoor natural skylight.

[0023] In this embodiment, before step S1, the method further includes: monitoring the environmental information of the indoor target area, the environmental information being used to trigger the pre-trained target detection model to identify the target information, and obtaining the real-time outdoor illuminance information when the target information includes a person.

[0024] Therefore, before simulating indoor sunlight in the above embodiments of this application, the presence perception of indoor personnel is introduced as the core enabling condition to achieve on-demand simulation of "lights following when people are present and lights turning off when people leave", thus saving energy.

[0025] In this embodiment, step S2 includes: establishing a time queue with a preset capacity, and updating the time queue according to the illuminance information at the current moment to obtain the illuminance information at the preset time.

[0026] For example, a first-in-first-out (FIFO) time queue of length ΔT (e.g., 10 minutes) continuously records illuminance information.

[0027] Therefore, this embodiment, by introducing a first-in-first-out time queue, can continuously and dynamically cache recent illuminance data. While automatically eliminating outdated and redundant information, it provides stable and efficient data support for subsequent accurate calculation of illuminance change rate and identification of sunshine trends.

[0028] In this embodiment, the illuminance information at a preset number of time points includes: the illuminance information at the current time point and the illuminance information at multiple historical time points. Step S2 includes: determining the rate of change of illuminance within a preset number of time points based on the illuminance information at the current time point, the illuminance information of the earliest historical time point entering the time queue, and the preset number of time points. Therefore, this application does not compare a single instantaneous value with a fixed threshold, but rather calculates the rate of change of illuminance over consecutive time periods in the time queue. And analyze its time window The internal trend (continuous rise / continuous fall). Among them, This indicates the illuminance information at the current moment. This represents the illuminance information for the earliest historical moment to enter the time queue.

[0029] Therefore, it can be seen that this embodiment calculates... By analyzing the rate of change of illuminance over a period of time and its trend, the continuous change pattern of illuminance can be effectively identified, thereby avoiding misjudgment caused by instantaneous fluctuations and improving the accuracy and stability of illuminance status judgment.

[0030] In this embodiment, the trend threshold includes a first trend threshold, a second trend threshold, and a third trend threshold, and step S3 includes: within a first preset time period, the rate of change of illuminance is greater than the first trend threshold, and the sunshine trend is a sunrise trend, wherein the first trend threshold is the trend threshold corresponding to the sunrise trend; and within a second preset time period, the rate of change of illuminance is less than the second trend threshold, and the sunshine trend is a sunset trend, wherein the second trend threshold is the trend threshold corresponding to the sunset trend; and within a third preset time period, the rate of change of illuminance is less than the third trend threshold, and the sunshine trend is a stable midday sunshine trend, wherein the third trend threshold is the trend threshold corresponding to the stable midday sunshine trend.

[0031] For example, when R> ( If the first trend threshold is set, and the sunrise trend continues for a certain period of time (e.g., the first preset time period is 3 minutes), then it is determined to be a "sunrise trend". When R < ( If |R| < 2 (where |R| is the second trend threshold), then it is determined to be a "sunset trend". If the value is within the range, it is determined to be a "stable trend in midday sunlight".

[0032] Therefore, this embodiment, by setting multiple trend thresholds corresponding to different solar illumination trends (sunrise, sunset, and stable noon), can perform more refined and accurate pattern recognition of the rate of change of illumination, thereby achieving highly reliable determination of stable illumination states at sunrise, sunset, and noon, and improving the accuracy and adaptability of ambient illumination pattern judgment. It should be noted that, in order to accurately simulate sunlight, the solar illumination trend can be further refined into other trends, and the specific solar illumination trend is not limited to this embodiment.

[0033] In this embodiment, step S4 includes: when the sunlight trend is the sunrise trend, the lighting mode is the morning light mode; and when the sunlight trend is the sunset trend, the lighting mode is the evening light mode; and when the sunlight trend is the stable light trend, the lighting mode is the midday stable sunlight trend. Specifically, the morning light mode involves the lights gradually changing from off to 80% brightness and 5000K color temperature within 30 minutes, simulating natural wake-up. The evening light mode involves the lights gradually changing to 60% brightness and 3000K color temperature within 1 hour. The midday stable sunlight trend indicates stable illuminance, maintaining constant illumination.

[0034] Therefore, this embodiment achieves intelligent and dynamic response to changes in ambient light by directly mapping the identified solar radiation trends (sunrise, sunset, and stable noon) to specific lighting modes (morning light, sunset, and constant lighting) and setting corresponding brightness, color temperature, and gradient duration, thereby providing users with a more natural, comfortable, and circadian-compliant lighting experience.

[0035] Based on the same inventive concept, this application proposes an indoor sunlight simulation system, which includes: a light acquisition module for acquiring real-time outdoor illuminance information, wherein the real-time illuminance information is the outdoor illuminance information at the current moment; an intelligent control module for determining the rate of change of illuminance within a preset number of time periods based on the illuminance information at preset time periods; and determining the current outdoor solar trend based on the rate of change of illuminance and a preset trend threshold; and a light adjustment module for adjusting the indoor light mode according to the solar trend.

[0036] The inventors discovered that another existing method for simulating sunlight uses a static threshold illuminance sensor for control. For example, when the outdoor illuminance is below a certain fixed value (e.g., 100 lux), indoor lights are simply turned on. This method also has drawbacks: it cannot distinguish between "low illuminance caused by continuous cloudy days" and "illuminance decrease caused by sunset," thus failing to trigger a transitional light environment with "sunset" warm tones at dusk, nor accurately initiate "morning light" simulation at dawn. Furthermore, both HCL based on absolute time (absolute time means that a fixed lighting mode is used indoors at a certain moment or time period, and does not dynamically change according to real-time outdoor illuminance) and control based on static thresholds largely ignore the presence of people, often resulting in ineffective light simulations continuously occurring in unoccupied areas, leading to energy waste.

[0037] In this embodiment, the light acquisition module includes a first sensor installed outdoors to acquire outdoor illuminance information. The system also includes a second sensor installed indoors to monitor environmental information in the target area. This environmental information triggers a pre-trained target detection model to identify target information, and when the target information includes a person, it acquires real-time outdoor illuminance information. The light adjustment module includes LED lights installed indoors, and adjusts the brightness and color temperature of the LED lights within a preset time period to adjust the indoor lighting mode to a target mode. Target modes include: morning light mode, sunset mode, and a stable midday sunlight trend. The first sensor is an illuminance sensor, and the second sensor is a human presence sensor.

[0038] Therefore, this embodiment achieves intelligent dynamic control of indoor lighting by combining an outdoor illuminance sensor and an indoor occupant presence sensor. This method can not only accurately match and execute lighting modes that conform to natural rhythms, such as morning light and sunset, based on real-time changes in outdoor lighting (such as sunrise and sunset), but also activate lighting simulation only when people are detected indoors, effectively avoiding ineffective lighting and energy waste when no one is present. This significantly improves the energy efficiency of the system while enhancing lighting comfort and naturalness.

[0039] In this embodiment, the present invention provides an indoor sunlight simulation system, such as... Figure 2 As shown, the system includes: outdoor illuminance sensors, presence sensors distributed throughout the indoor zones, a KNX smart screen as the core control and interaction node, a light environment control module (KNX / DALI gateway), a dual-color temperature LED luminaire array, and a visual management platform. The system first checks the presence sensor signal in the corresponding indoor zone. This sensor can be connected to the KNX bus, and its status can be read by the smart screen. If there are no people in the zone, the system immediately enters a low-power monitoring state, not executing any light environment simulation programs, but only retaining basic data acquisition functions. When someone enters, the system reads the absolute value of the illuminance information uploaded by the outdoor illuminance sensor in real time via the KNX bus. The system instantly restores the current simulation state (e.g., if it is during sunset, it restores the sunset simulation), rather than simply turning on the lights.

[0040] Therefore, the indoor sunlight simulation system of this application completes the simulation of sunlight by performing the following steps. (1) Sunrise Simulation: When the sunlight trend is the sunrise trend and there are people in the target area, the system triggers the "Morning Light Mode". The smart screen sends instructions to the KNX bus through its "color temperature adjustment function" or "scene call" function. The light environment control module (gateway) converts these instructions into the DALI DT8 protocol, controls the color temperature of the LED lights to smoothly transition from 2700K to 5700K, and the brightness to increase linearly from low to high, simulating the process of the sky gradually brightening in the early morning.

[0041] (2) Sunset simulation: After the sunlight trend becomes a sunset trend, the "sunset mode" is triggered. The control command drives the color temperature of the LED lights to transition to a warm tone below 3000K, and the brightness slowly decreases to create a dusk atmosphere.

[0042] (3) Noon simulation: During stable periods such as noon, the system maintains constant light parameters. Users can manually override the automatic mode at any time via smart screen, mobile APP or management software. The system records this intervention and uses it as a reference during subsequent automatic operation.

[0043] In this embodiment, the built-in "threshold comparator" logic function and "delay function" of the smart screen can be used to implement the basic logic for calculating the illuminance change rate and judging the sunshine trend, without the need for an additional advanced controller. This application can dynamically generate or adjust the time curve of HCL. For example, when the system detects that today's sunrise is later than the preset time, it can automatically postpone the start time of the "morning light" simulation accordingly, upgrading HCL from "pre-programmed" to "adaptive". The system can use the geographic coordinate information configured in the smart screen's "night mode settings" as a reference for the approximate sunrise and sunset times, combined with real-time trend judgment, to improve the accuracy of the judgment and to display the estimated day and night status on the visualization interface.

[0044] Take an office area as an example: 1. Equipment Deployment: An outdoor illuminance sensor will be installed on the east exterior wall of the building and connected to the KNX bus. A KNX Smart Screen Z10 (as an area controller) and a presence sensor will be installed in the office area. All dual-color temperature downlights will be connected to the lighting environment control module (KNX-DALI gateway) via a DALI driver.

[0045] 2. Parameter Configuration: Configure the logical function channels for the smart screen using ETS software, and write the logic for judging sunlight trends based on the rate of change of illuminance. Set the final target color temperature and brightness, as well as the duration of change, for scenes such as "morning light" and "sunset".

[0046] Outdoor illuminance sensors collect data and transmit it to the lighting environment control module via the KNX bus. A person presence sensor also connects to the KNX bus, providing an enable signal. The lighting environment control module (or integrated into a multi-functional gateway) incorporates the aforementioned lighting mode control algorithm. It acts not only as a data relay but also as the brain, responsible for analyzing illuminance trends and generating control strategies. Dual-color temperature LED downlights receive DALI commands from the KNX bus, changing their brightness and color temperature to complete the light simulation. The smart screen and central control software management host can manually override the automatic mode and view the current simulation status (e.g., displaying "Sunrise Simulation in Progress").

[0047] In summary, the beneficial effects of the above embodiments of this application include the following: (1) Intelligent leap in environmental perception: This application continuously monitors and calculates the rate of change of outdoor illuminance and its duration to determine natural light state transition events such as "sunrise begins" and "sunset begins" in real time, rather than relying on preset absolute time points or simple static illuminance threshold comparisons. This upgrade from "watching the clock" or "watching the brightness of a single point" to "watching the trend of light changes" can accurately capture dynamic transition moments such as dawn and dusk, simulating more realistic and emotional moments. (2) Significant energy-saving effect: The signal of the personnel presence sensor is used as the necessary enable switch for indoor sunlight simulation programs (such as morning light mode and sunset mode), realizing the strict sense of "lights follow people and lights turn off when people leave" intelligent linkage, and seamlessly restoring the current dynamic simulation state when people enter. The deep binding of personnel presence perception and light simulation fundamentally eliminates ineffective lighting and meets the highest standards of green building requirements. (3) Excellent user experience: The indoor sunlight simulation system proposed in this application includes an outdoor illuminance sensor, a KNX smart screen (with built-in logic judgment function), a personnel presence sensor, a light environment control module, and dual-color temperature LED lamps. Through the KNX bus and DALI network, a complete closed-loop control link is realized, from environmental trend perception and intelligent logic judgment to precise dimming and color adjustment of the lamps. Based on the mature KNX / DALI architecture and the powerful processing capabilities of the smart screen, the system is stable and reliable. The threshold for trend judgment and the parameters of the simulated scene can be flexibly configured through the ETS software or the smart screen interface to adapt to the needs of different regions and spaces. It supports multiple interaction methods such as automatic simulation, manual control, scene calling, and visual monitoring (through the management platform) to meet the diverse needs of end users and administrators.
