2 is a schematic diagram illustrating a process of selecting an action plan using measured data by a lighting system according to an exemplary embodiment.

The lighting system 1 may calculate an air quality index by combining a plurality of data measured by each sensor of the measuring unit 11. In detail, the lighting system 1 may calculate the air quality index by multiplying a plurality of data measured by each sensor of the measuring unit 11 for each measurement object, and summing all of them. For example, the data measured by a carbon dioxide sensor, a radon sensor, a dust sensor, etc. may be A ₁ , A ₂ , A ₃ ,. , A _i , the weights α ₁ , α ₂ , α ₃ ,... , α _i may be multiplied by each measurement data and summed to calculate the air quality index. If this is expressed as an expression, it is as follows.

That is, the air quality index may mean a comprehensive score for indoor air.

The lighting system 1 can assign an air quality rating to the current indoor air condition using the calculated air quality index. Specifically, the lighting system 1 may assign an air quality grade for each section according to the calculated air quality index. That is, the air quality grade may mean a comprehensive grade for indoor air.

The lighting system 1 may select an action plan that is most suitable for the user according to the given air quality class and provide the user with the selected action plan. The action plan may include information about the actions that are best suited for the user to perform at present. That is, the lighting system 1 analyzes the indoor air quality, selects an action plan based on this, and provides the selected action plan to the user, thereby inducing the user to perform the most appropriate action in the current state.

The action plan may include information about the action suggested to the user. Information on the proposed action includes a ventilation proposal, a window opening proposal, an external air blocking proposal, a window closing proposal, an air cleaning proposal, an air purifier control proposal, a humidifier control proposal, an oxygen generator control proposal, a fan control proposal, and a heater control proposal.

For example, if the indoor air is bad and the outside air is good, the lighting system 1 may select a ventilation proposal or window opening proposal as an action plan and provide it to the user to induce the user to ventilate or open the window. have. Alternatively, if the indoor air is good and the outside air is bad, the lighting system 1 selects an outside air blocking proposal or a window closing proposal as an action plan, and provides the user with the action to induce the user to block the outside air or close the window. Can be. On the other hand, when the indoor air is bad and the outside air is bad, the lighting system 1 selects an air cleaning proposal or an air purifier control proposal as an action plan, and provides the user with the air to clean the air or operate the air cleaner. It can be induced to work harder. In addition, the lighting system 1 may select an action plan such as a humidifier control proposal, a fan control proposal, etc. according to a situation, and provide the same to a user, thereby inducing a user to perform an appropriate action.

The lighting system 1 may take into account the spatial information in order to select the action plan most suitable for the current air quality situation. The air quality management method varies according to the purpose, size, type, use, etc. of the indoor space where the user stays, and the required management standards may also vary. For example, the main room where the user stays may need to strictly control the air quality, and in the bathroom, it may be important to reduce the humidity. In addition, even in the same space, by subdividing the space, the presence and the location of the ventilator, the presence and the location of the ventilation openings, the presence and the location of the window, the presence and absence of the entrance and exit may be relatively different, according to the air quality, air quality management method And management criteria may also vary. For example, in the air quality sensor located near the doorway, dust may be measured higher than in other places, and in the air quality sensor located far from the air vent, the concentration of carbon dioxide may be high.

Therefore, the lighting system 1, in the process of selecting an action plan, spatial information, that is, the purpose, size, type, use of the space, the presence and location of the ventilator, the presence and location of the vents, the presence and location of the windows, The plan of action may be selected in consideration of at least one or more of the presence and the location of the doorway. The spatial information is information about a space where the lighting system is installed, and is a fixed value that does not change with time, and may be set differently for each installation location. Spatial information can be considered to determine weights that are multiplied by the data measured at each sensor. Spatial information can be taken into account in determining the numerical interval of the air quality index that is the class criterion of the air quality class. Spatial information may also be considered in selecting action plans based on air quality ratings.

The lighting system 1 may take environmental information into account in order to select the action plan that is most appropriate for the current air quality situation. Even if they belong to the same air quality class, you may need to select an action plan based on the time of day and season. For example, even in situations with the same air quality class, it may be necessary to ventilate in summer and to clean in winter. In addition, you may need to choose an action plan that takes into account external weather, fine dust forecasts, ultrafine dust forecasts, ozone forecasts, and yellow dust forecasts. For example, if the indoor air quality is bad, but the outdoor air quality is worse due to fine dust forecasting, etc., it may be necessary to select indoor air cleanness instead of ventilation as an action plan. In addition, the presence or absence of occupants, the number of occupants, the position of the occupants and the state of the occupants may also be considered. For example, it may not be necessary to strictly apply air quality rating standards if there are no occupants, and if you have infants or elderly people who are in poor health or need health care, you should strictly apply the air quality rating standards. Can be.

Therefore, the lighting system 1, in the process of selecting an action plan, includes environmental information such as time, season, weather, fine dust forecast, ultrafine dust forecast, ozone forecast, yellow dust forecast, presence of occupants and the number of occupants The plan of action may be selected in consideration of at least one or more of the occupant's location and the occupant's condition in real time. Environmental information can be considered to determine the weights multiplied by the data measured at each sensor. Environmental information can be taken into account in determining the numerical interval of the air quality index which is the class criterion of the air quality class. Environmental information may also be considered in the selection of action plans based on air quality ratings.

Since the environmental information may change in real time, it may need to be reflected in real time. External weather, fine dust forecasts, ultrafine dust forecasts, ozone forecasts, and yellow dust forecasts are available from external sources. For example, the lighting system 1 may use data provided by the National Air Pollution Information Management System (NAMIS). Here, the National Air Pollution Information Management System collects and manages air pollution data such as sulfur dioxide, carbon monoxide, nitrogen dioxide, ozone, and fine dust at measuring stations located nationwide. The lighting system 1 may use the infrastructure related to the air pollution measurement network measured and provided in the national air pollution information management system. In addition, the lighting system 1 expresses various measurement data of five air environmental reference substances measured in 289 urban air monitoring networks, roadside atmospheric monitoring networks, national background monitoring networks, and suburban air monitoring networks installed in 89 cities and counties nationwide. You can use the data of Air Korea to provide the people in real time. In addition, the illumination system 1 can also use data, such as a yellow dust alarm operated by the Meteorological Agency and an ozone alarm operated by a local government. As such, the lighting system 1 may use various air pollution related data provided by the national air pollution information management system, Air Korea, the Korea Meteorological Agency, and local governments. In order to collect and use the external data, the lighting system 1 may further include an external data collection unit for collecting the external data. Alternatively, the lighting system 1 may collect and use the external data through the user terminal T.

The lighting system 1 may include a motion detection sensor in the measuring unit 11 to determine the presence or absence of occupants, the number of occupants and the positions of the occupants. The lighting system 1 may determine whether there are occupants, the number of occupants, and the positions of the occupants through the motion detection sensor, and select a suitable action plan by reflecting them in real time.

The lighting system 1 may directly consider the data measured at each sensor in the course of selecting an action plan. For example, the lighting system 1 may select a humidifier control proposal as an action plan to induce the user to adjust the humidity if the humidity is significantly lower, apart from the air quality rating.

The process of selecting the above-described action plan may occur at the user's terminal (T). That is, the lighting system 1 may perform the above process through the application installed on the user's terminal T or the web, the internal network, the Internet, and the like. Specifically, calculating the air quality index by multiplying and summing the data measured by the measuring unit 11, adding the air quality grade using the air quality index, air quality grade, spatial information, environmental information and measured data In consideration of the step of selecting an action plan may be performed in the user terminal (T). In this case, the terminal T receives the measured data from the communication unit 12 and processes the data to calculate the air quality index, air quality grade and action plan, and calculates the calculated air quality index, air quality grade and action plan Can be provided to the user through the display. In addition, the terminal T may transmit the calculated air quality index, air quality grade, and action plan to the communication unit 12 of the lighting system 1.

The lighting system 1 may further include an operation unit capable of performing data operation, and calculating and calculating an air quality index by multiplying and summing data measured in the measuring unit 11, and using the air quality index. The step of assigning the step, selecting the action plan in consideration of the air quality grade, spatial information, environmental information and measured data may be performed in the calculation unit of the lighting system (1). In this case, the communication unit 12 transmits at least one or more of the air quality index, the air quality grade, and the action plan calculated by the calculation unit to the user's terminal T, and the terminal T receives the received air quality index, the air quality grade, and the action plan. At least one or more may be provided to the user through the display of the terminal T.

The lighting system 1 can use a variety of methods to provide a user with a selected action plan. As mentioned above, the lighting system 1 may visually provide the user with information about the action plan through the display of the terminal T. FIG. The display of the terminal T may visually express a numerical value, an air quality index, an air quality grade, and an action plan of data measured by each sensor.

Alternatively, the lighting system 1 may further comprise an auxiliary light source 14 to provide the user with a selected action plan. The auxiliary light source 14 may include a light source capable of producing various colors. The controller 13 may change at least one or more of the color, illuminance, and lighting state of the auxiliary light source 14 to correspond to the action plan according to the selected action plan. For example, the controller 13 may blink to change the color of the auxiliary light source 14 to flicker. Therefore, the user can determine which action plan is selected through the color, illuminance and lighting state of the auxiliary light source 14. Alternatively, the controller 13 may change at least one or more of the color, illuminance, and lighting state of the lighting unit 10 to correspond to the action plan according to the selected action plan.

On the other hand, the lighting system 1 may further include a sound generator for generating a sound. The sound generator may generate various sounds through a prestored sound source. The controller 13 may control the sound generator to generate a sound corresponding to the action plan according to the selected action plan. Alternatively, the lighting system 1 may generate a sound corresponding to the selected action plan through a speaker built in the terminal T. For example, the lighting system 1 generates a specific sound through the speaker of the sound generating unit or the terminal T in a situation where the air quality grade is very bad or when an action plan requiring urgent action is selected. You can notify the user.

In addition, the lighting system 1 may provide information such as an action plan to the user through push notification, text transmission, web site, etc. of an application installed in the terminal T.

The lighting system 1 may further comprise an LED sterilizer 15. In this case, the measuring unit 11 may include a floating bacteria sensor. The lighting system 1 may select an action plan in consideration of the data measured by the airborne bacteria sensor. For example, if the data measured by the airborne bacterium sensor is above a certain value, the lighting system 1 may select an action plan for operating the LED sterilizer. The controller 13 may control the LED sterilizer 15 according to the selected action plan. The lighting system 1 including the LED sterilizer 15 and the airborne bacterium sensor may be installed in a bathroom or the like where a lot of bacteria are distributed.

The lighting system 1 may further include a fragrance generating unit 16. The controller 13 may control the fragrance generating unit 16 according to the selected action plan.

Control of the control device C may be made by remote communication through the communication unit 12, or may be made by wire.

The lighting system 1 may comprise various modes. The controller 13 may include a management mode for indoor air quality management. The management mode may be a mode in which a user may immediately provide a selected action plan through the state of the lighting unit 10 and return the state of the lighting unit 10 to its original state as the user performs the selected action plan. . In detail, in the management mode, the controller 13 may change at least one or more of the color, illuminance, and lighting state of the lighting unit 10 to correspond to the selected action plan. The user may be immediately provided with information on the selected action plan by changing the state of the lighting unit 10, and thus may perform an operation corresponding to the action plan. In the management mode, when the controller 13 recognizes that the user has performed the action plan, the controller 13 may return the state of the lighting unit 10 to its original state. The user performing the action plan may be recognized through a change in data, air quality index, or air quality grade measured by the measuring unit 11. Alternatively, the communication unit 12 may receive and recognize that each control device C is controlled. Since the management mode directly controls the state of the lighting unit 10 that illuminates the room, the user can immediately respond to the change in the room light. In addition, since the state of the lighting unit 10 is returned to the original state by reflecting whether the user has performed the provided action plan, it is possible to induce an immediate action of the user. The management mode may include feedback of the user's performance plan performance, thus contributing to keeping the indoor air comfortable at all times.

On the other hand, the controller 13 may include an automatic control mode. The automatic control mode may be a mode in which the control unit 13 directly controls various control devices C according to the selected action plan. In the automatic control mode, it may be convenient in that the user does not have to perform an action plan.

In addition, the controller 13 may include a sleep mode. The sleep mode may not provide an action plan to the user when the lighting unit 10 is turned off. Alternatively, the sleep mode may not provide an action plan to the user when the lighting unit 10 is turned off while the user sets a time zone. In this case, since the user may be turning off the light of the lighting unit 10, the user may not disturb the user's bed by not providing an action plan to the user. The user may select a time zone in which the sleep mode is applied. The sleep mode is merged with the automatic control mode so that when the sleep mode is set, the automatic control mode may be automatically set. That is, when the sleep mode is set, the controller 13 may directly control various control devices C instead of providing an action plan to the user.

The management mode, the automatic control mode, and the sleep mode may be set or released by the user. The management mode, the automatic control mode, and the sleep mode may be set or released through the terminal T according to the user's selection.
