[0002] In modern cities and building environments, lighting systems play a vital role. Existing smart lighting methods and systems based on the Internet of Things, compared with traditional lighting systems, will automatically adjust the lighting intensity and mode according to environmental changes and customer usage needs.

[0003] However, the existing intelligent lighting system is highly dependent on the setting of sensors, such as indoor illuminance devices, personnel monitoring sensors, solar radiation sensors, illuminance sensors, color temperature sensors, dimming lamps and dimming controllers, etc., and the arranged sensors are easily affected by the location, quantity and their own failures, making it difficult to obtain analog data. As a result, the initial investment and operation and maintenance of the entire control system are cumbersome and costly, and it is also unable to meet the more accurate and appropriate adjustment of the indoor light environment, affecting the lighting energy consumption of the building.

[0004] In addition, the existing real-time analysis system of the operating status of the intelligent lighting system basically relies on fixed values, has poor control effect on the indoor light environment, and lacks the use of specific threshold parameters for scene-based control.

[0005] Third, the existing intelligent lighting system mainly adopts manual or remote control strategies. It is unable to automatically adjust according to the occupancy of people and the ambient brightness. And it does not consider the use of natural lighting with the sunshade system, which leads to the indoor lighting being fully turned on for a long time, resulting in energy waste and is not conducive to the adjustment and use of the indoor light environment.

[0006] Therefore, a lighting system or method is needed to solve this technical problem, which can centrally summarize various sensors, perform real-time simulation, and automatically adjust according to occupancy of personnel and ambient brightness. Summary of the invention

[0018] More preferably, the solar spectrum lamp intelligent lighting system is connected to the indoor environment monitor of the air-conditioning system, and the indoor environment monitor of the air-conditioning system is used to monitor the current indoor carbon dioxide concentration in real time, and the monitored carbon dioxide concentration is sent to the simulation calculation module in the form of data; the air-conditioning system is electrically connected to the simulation calculation module; the indoor environment monitor of the air-conditioning can utilize this basic function to monitor the real-time changes of the indoor carbon dioxide concentration, thereby replacing the personnel monitoring sensor in the indoor traditional intelligent lighting system, so as to determine the indoor personnel retention situation.

[0019] The present invention also discloses a control method for a smart lighting system, the control method is used to control the above-mentioned smart lighting system, and the control method comprises the following steps:

[0020] Step 1: After the sensor collects outdoor environmental data in real time, it transmits the current outdoor weather conditions in the form of data to the data collection host; specifically: the fully automatic tracking solar radiation transmitter receives sunlight from the outdoors, and transmits the wavelength and brightness of the current sunlight in the form of data to the data collection host, the solar total radiation sensor receives the sunlight intensity from the outdoors, and transmits the current solar intensity in the form of data to the data collection host, the solar tilt radiation sensor receives the sunlight angle from the outdoors, and transmits the current sunlight angle in the form of data to the data collection host, and a variety of meteorological sensors receive real-time weather conditions from the outdoors, and transmit the current outdoor weather conditions in the form of data to the data collection host;

[0022] Step 3: The simulation computing platform receives and processes the outdoor environment data and then uploads it back to the environmental monitoring cloud platform; specifically: the simulation computing platform in the simulation computing module receives and processes the data of sunlight intensity, sunlight angle, wavelength and brightness, and real-time weather conditions sent by the environmental monitoring cloud platform, and performs real-time simulation analysis. After that, the simulation computing platform uploads the real-time simulation analysis results of the indoor light environment of the building back to the environmental monitoring cloud platform in the form of data;

[0023] Step 4: The indoor environment monitor monitors the indoor carbon dioxide concentration and sends it to the simulation computing platform, and the simulation computing platform determines whether to issue a control instruction to the lighting system control platform; specifically: the indoor environment monitor in the air-conditioning system measures the current indoor carbon dioxide concentration, and sends the carbon dioxide concentration at this moment in the form of data to the simulation computing platform. If the calculated carbon dioxide value is less than 500, the real-time simulation analysis result data of the building indoor light environment is not sent to the first network communication module in the lighting system control module; if the calculated carbon dioxide value reaches and exceeds 500, the real-time simulation analysis result data of the building indoor light environment is sent to the first network communication module in the lighting system control module for control instructions;

[0024] Step 5: The lighting system control platform receives the control instruction and performs scene-based adjustment on the solar spectrum lamp; specifically, the first network communication module in the lighting system control module obtains the real-time simulation analysis result data of the building indoor light environment at the current time stored in the Internet of Things control system through the simulation calculation platform in the simulation calculation module, and transmits it to the lighting system control platform in the lighting system control module in the form of data, and then performs scene-based adjustment on the solar spectrum lamp through the brightness adjustment module and the color temperature adjustment module;

[0025] Step 6: The lighting system control platform feeds back the adjustment data of the solar spectrum lamp to the simulation computing platform and the environmental monitoring cloud platform; specifically: the lighting system control platform transmits the adjusted solar spectrum light brightness and color temperature in the form of data back to the first network communication module, and the first network communication module transmits the real-time situation of the building's indoor light environment processed by the lighting system control platform back to the simulation computing module in the form of data.

[0026] Preferably, in step 5, the scene-based adjustment includes the following scene modes:

[0027] Scenario 1: When the light intensity drops to between 40 and 50 lux, the noon mode is triggered, which automatically turns on the main lighting device and sets the initial brightness to 30%. The blinds of the sunshade system are all lowered, with a fixed tilt angle of 60°, and the indoor light color temperature is in cool color mode.

[0028] Scenario 2: When the light intensity drops to between 10 and 30 lux, the evening mode is triggered, the brightness is increased to 60%, and the indoor auxiliary lighting equipment is turned on.

[0029] Scenario 3: When the light intensity drops below 10 lux, the early morning and night modes are triggered, the brightness is adjusted to the highest, and the color temperature may be adjusted to 2700K to provide a warmer lighting environment. At the same time, a coordination strategy is implemented to control the cross-lighting devices and raise all the blinds of the shading system to ensure that all lighting equipment is in the best working condition.

[0032] 2. The present invention replaces the personnel monitoring sensor in the traditional indoor smart lighting system with the indoor environment monitor in the air-conditioning system, that is, by analyzing the threshold parameter changes of the monitor's carbon dioxide, the retention of indoor personnel is determined. In this way, the determination of the retention of indoor personnel is achieved by using the established air quality monitoring system in the air-conditioning system, meeting the personnel monitoring needs of the smart lighting control of the present invention. At the same time, it can also avoid the involvement of a large number of sensors, indoor wiring problems, etc., which lead to cumbersome and costly initial investment and operation and maintenance of the entire control system.

[0033] 3. The present invention adopts a wireless Internet of Things control system, and the lighting system control platform uniformly regulates the indoor light environment of the smart lighting system and the smart sunshade system, which solves the problem of relative separation between the traditional smart lighting system and the sunshade system, and enables the roller blinds or shutters in the smart sunshade system to track the sunlight and automatically adjust the height and angle; the solar spectrum smart lighting device in the system of the present invention automatically adjusts the light intensity according to the indoor environment data simulated by the outdoor real-time monitoring perception platform, thereby realizing the organic linkage of daylighting, sunshade and lighting.
