Description

A pattern-based intelligence sesibility lighting system

The present invention is a pattern-based method of vectorizing measurement values for detecting indoor environment and behavior of residents, control commands and states of lighting equipment, and preconfiguring pattern vectors having a range of vector elements or generating or updating pattern vectors through learning. Emotional lighting system.

In general, a lighting device refers to a device that provides light to a human being to obtain visual information, and was limited to only a function of illuminating darkness. However, using the mental effects of color temperature in the lighting device can be a means of making the interior space more comfortable.

Therefore, it is necessary to set a variety of lighting environments to produce more human-centered natural lighting changes in the room, and to select them according to need, and to provide a sensitive lighting environment. Emotional lighting is a state-of-the-art lighting technology that can change space while applying color temperature and brightness to a person's psychological state.

An example of such an emotional lighting technology is [Korean Patent Publication No. 2011-0025579 (published on March 10, 2010), "Sensor control LED lighting method and apparatus"] (hereinafter Prior Art 1), [Korean Patent Publication No. 2011-0076379 (Published Jul. 6, 2011), "apparatus and method for adaptive production equipment control and recording medium"] (hereinafter, prior art 2), [Korea Patent Publication No. 2011-0113437 (published Oct. 17, 2011), "Ship passenger Emotion recognition lighting control system using biometric information of "" (hereinafter referred to as prior art 3) and the like.

The prior art 1 is a technology related to LED lighting to detect the illuminance, temperature, humidity, the human body automatically on / off or adjust the brightness to save power.

In addition, the prior art 2 is an environment defining unit for storing the lighting device control signal, the audio device control signal and the video device control signal for each theme to be produced by the user; Cognitive sensors for measuring ambient temperature, ambient noise and ambient illuminance; And a cognitive adaptation unit that selects any one of the themes according to the measured values of the ambient temperature, ambient noise, and ambient illuminance, and outputs a lighting device control signal, an audio device control signal, and an image device control signal corresponding to the selected theme. Thus, a technique of changing lighting or the like in response to a user's emotion or environment is disclosed.

In addition, the prior art 3 comprises a plurality of sensors for collecting biometric information of the ship occupant including at least one of pulse, blood pressure, blood sugar and stress; A controller for classifying the emotion of the occupant according to the biometric information using a diagnostic algorithm and outputting a control signal corresponding to the emotion; And a light driver for controlling a lamp according to the control signal.

However, the prior art simply describes sensing a human or environmental state and controlling the lighting to suit the state. That is, there is a problem in that it is necessary to know and set in advance which lighting is suitable for each state. After all, the preference for lighting may vary from person to person, such as taste, but cannot be controlled in consideration of this.

One example is described below.

A student is studying under a standlight with emotional lighting. Suppose the product is designed to focus on learning by adjusting the color temperature according to a certain area. This student is studying hard and starts to doze off. Should the stand create sleep-disturbing lights to keep you sleepy, or should you provide comfortable lighting for a short break? As such, most existing systems operate based on preset information that has been pre-populated or some information calculated from some data, especially when there are multiple users. It is not easy to respond.

 As in the example above, the existing system works with just a preconfigured preset and some sensor response. In other words, it only reacts immediately and cannot understand and act on the system itself.

Therefore, there is a need for a more emotional lighting technology that can recognize a user's behavior and changing environment and implement lighting corresponding thereto. In other words, there is a need for a technology that can more easily set up and process emotional lighting control.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In the description of the present invention, the same parts are denoted by the same reference numerals, and repetitive description thereof will be omitted.

First, examples of the configuration of the entire system for carrying out the present invention will be described with reference to Fig.

As shown in FIG. 1, an example of the whole system for the implementation of the present invention consists of a resident 10, a sensor 20, a lighting device 30, and an emotional lighting system 50. In addition, the sensor 20 and the lighting device 30 is installed in the room (40). In addition, it may be configured to further include a database 60 for storing data.

The sensor 20 is a sensor capable of measuring the environment (or indoor environment) of the room 40, and is a temperature sensor, a humidity sensor, an illuminance sensor, a time, a volume sensor, or the like. The interior 40 refers to an interior space of a building, an office, a room, or the like. In other words, the indoor environment refers to an environment such as indoor temperature, humidity, illumination, and noise. The indoor environment, such as temperature, humidity, noise, and time, is displayed as a measure (or numerical value).

Alternatively, the sensor 20 may detect a behavior of a resident 10 through a camera, an infrared sensor, a pulse, and the like. In this case, the measurement value of the sensor 20 is to display the position, posture, body temperature and the like of the resident 10.

The sensor 20 may be fixed to the room 40 and installed. Alternatively, the sensor 20 may be embedded in an object worn or possessed by the resident 10. Alternatively, the sensor 20 may be measured manually by a person. The sensor 20 may be implemented in any form as long as it can measure the indoor environment or the behavior or state of the occupant 10 in real time.

The indoor environment measured by the sensor 20 is displayed as a numerical value (or measured value), and the measured value is transmitted to the emotional lighting system 50. The sensor 20 is connected to the emotional lighting system 50 to enable data communication. In this case, the data communication may be wired communication connected by a communication line, or wireless communication such as Bluetooth, WiFi, Zigbee, and 3G mobile communication network.

The lighting device 30 is a device for illuminating an indoor environment, and refers to a device capable of illuminating in various forms by adjusting various control elements such as on / off, blinking, brightness, color temperature, and irradiation direction.

Meanwhile, the lighting device 30 is connected to the emotional lighting system 50 and controlled according to a control command received from the emotional lighting system 50. That is, the lighting device 30 controls its on / off or brightness by a control command.

In addition, the lighting device 30 may be directly controlled by the occupant 10. It may also be controlled by a control means such as a switch provided in the lighting device 10 or a remote control. The control by the occupant 10 takes precedence over the control command of the emotional lighting system 50. For example, if the emotional lighting system 50 transmits a control signal for lowering the brightness and the occupant 10 increases the brightness through a switch or the like, the lighting device 30 responds to the control command of the high priority occupant 10. Follow.

In this case, the emotional lighting system 50 may receive a control state from the lighting device 30. That is, the emotional lighting system 50 may know the control state (or lighting state) desired by the occupant 10.

Emotional lighting system 50 collects the indoor environment status information or resident behavior (or resident behavior) detected from the sensor 20, by using this to determine the optimal lighting of the indoor environment based on the lighting device 30 To control. That is, the emotional lighting system 50 adjusts the lighting device 30 on / off, blink brightness, etc., to create an optimal emotional lighting.

On the other hand, the emotional lighting system 50 stores the lighting control commands for the pattern in advance by patterning the indoor environment information and the resident behavior. When receiving the detected indoor environment and the resident behavior from the sensor 20, it determines which pattern the received information corresponds to and transmits a lighting control command corresponding to (or corresponding to) the lighting pattern to the lighting device 30. do.

In addition, if the indoor lighting information and the resident behavior does not match the previously stored patterns, the emotional lighting system 50 creates a new pattern or learns and updates the existing pattern.

In addition, the emotional lighting system 50 makes a new pattern or learns an existing pattern even when receiving a lighting control state different from the lighting control command corresponding to the existing pattern. This refers to a case where the occupant 10 issues an illumination control command, unlike the control command specified in the pattern. At this time, the existing pattern may be further subdivided to create a new pattern.

The database 60 includes a pattern DB 61 storing a pattern vector obtained by vectorizing a pattern, and a learning DB 62 storing data learned from environmental information and control state information corresponding thereto. However, the configuration of the database 60 is only a preferred embodiment, and in the development of a specific device, the structure of the database 60 may be configured in a different structure by a database construction theory in consideration of the ease and efficiency of access and retrieval.

Next, the configuration of the pattern-based emotional lighting system according to an embodiment of the present invention will be described in more detail with reference to FIG. 3.

As shown in FIG. 3, the emotional lighting system 50 includes an environment recognition unit 51, a control configuration unit 52, a pattern storage unit 53, a pattern matching unit 54, and an illumination implementation unit 55. It consists of. In addition, the pattern learning unit 56 may be configured by adding.

The environmental recognition unit 51 receives measurement values from a plurality of detection sensors 20 for detecting indoor environment and resident behavior, and configures the measurement values as vectors (hereinafter, environmental vectors).

As described above, the sensor 20 is a sensor that can measure the indoor environment or the resident behavior, such as temperature sensor, humidity sensor, clock, volume sensor, motion detection sensor. In addition to the infrared sensor, the motion sensor may detect a resident's position or the degree of movement through a camera.

As an example, the element that can be detected by the environmental recognition unit 51 is determined by the position of the occupant, the degree of movement of the occupant, the duration of the movement, and the current time. In addition, the room 40 is set to the room where the student lives.

The measuring elements (or sensing elements) by the sensing sensor 20 are converted into measurements. The occupant's position is divided into a desk and a bed, and 1 and 2 are measured respectively. In addition, the degree of movement is divided into six stages from 0 to 5, and if there is no movement at all, it is set to 0, and the case where the movement is detected very quickly is set to 5 at maximum. The duration of the movement is determined by the duration of the movement. However, in consideration of the case where a fast movement is detected, there is no movement for a while, and then there is a rapid movement, it is desirable to determine the total movement time excluding the exceptional movement in the middle.

The environment vector for the above example may be expressed as follows.

Environment vector = (<location>, <current time>, <motion>, <duration>)

The elements of the environment vector are measurements of sensing elements for the occupant's location, current time, occupant's movement intensity, and duration of movement.

On the other hand, it is preferable that the environmental recognition unit 51 receives the measured value periodically or receives an input only when there is a change in the measured value. For example, the measurement value may be input at an interval of 1 minute, and an event may be generated and received when the position is changed from 1 to 2 by the position sensor.

The control unit 52 configures a command for controlling the lighting apparatus into a vector (hereinafter referred to as a control vector) or configures a lighting apparatus state into a vector (hereinafter referred to as a state vector).

As described above, the lighting device 30 is a lighting device that is controlled by various control elements such as on / off, blinking, brightness, irradiation direction. In the previous example, the student's room has one light and the control element of the light is on / off / brightness element and blinking element. The on / off / brightness element has a control value of 0-5. 0 indicates that the power is turned off, 1-5 indicates that the power of the lighting device 30 is on, and each number represents a degree of brightness. In addition, the flicker is to control whether the lighting device 30 repeats the flashing. 0 means no flicker and 1 means flicker.

Therefore, the control vector can be expressed as follows.

Control Vector = (<On / Off / Brightness>, <Blink>)

The control vector and the state vector are represented by a vector of the same format. However, the control vector indicates a control command transmitted from the emotional lighting system 50 to the lighting device 30, and the state vector indicates the control state of the lighting device 30 controlled by the occupant 10.

On the other hand, the information about the state vector is preferably received only when there is a change. For example, when the brightness is raised by the occupant 10, an event may be generated and input.

The pattern storage unit 53 stores a pattern vector composed of the range of the measured value and a control vector corresponding to the pattern vector.

The pattern vector is a pattern of indoor environment information and occupant behavior, and is composed of these measurements or ranges. Therefore, the elements of the pattern vector are the same as the elements of the environment vector. The difference is that the value of the element is not a simple measure but a range.

In the previous example, the elements of the pattern vector are

Pattern vector = (<position>, <current time>, <motion>, <duration>)

An example of the pattern vector is shown in FIG.

In the table of Fig. 3, the position of the pattern vector is described with the position, the <position>, the <current time>, the <motion> and the <duration time>, and these lines immediately indicate the elements of the pattern vector. The pattern vectors represent three, and the pattern vector 1 shows that the occupant is at the desk, the time is between 7 pm (19:00) and 7:00 the next morning, and the duration is 20 minutes without motion. It is patterned. In addition, pattern vector 3 is a pattern of the case where the occupant is located in the bed, the time is between 7:00 pm (19:00) and 7:00 the next morning, and the duration is 30 minutes without movement.

On the other hand, the element of the pattern vector may have a value including all the values. In the example of FIG. 3, the duration of pattern 3 is indicated by "-", and includes all of the durations at any time.

Each pattern vector has a control vector corresponding to each pattern. For example, in the case of the pattern vector 1, the control vector is (4, 1), and has on / off / brightness of 4 and flickering of 1. That is, the brightness of the lighting device 30 is set to 4 (on) and flickers. In the case of the pattern vector 3, the control vector is (0,0), and has on / off / brightness 0 and flickering 0. That is, the lighting device 30 is turned off.

The meaning of pattern 1 is as follows. If the occupant is at the desk, and the time is between 7:00 pm (19:00) and 7:00 the next morning, and the duration is 20 minutes without motion, the brightness of the lighting device 30 is set to 4 on) and blink.

The meaning of pattern 3 is as follows. If the occupant is in bed and the time is between 7:00 pm (19:00) and 7:00 the next morning and the duration is 30 minutes without motion, the luminaire 30 is turned off.

Such a pattern may be created and stored in advance, or as described below, a new pattern or an existing pattern may be updated by learning.

The pattern matching unit 54 determines whether or not the measurement values of the environment vectors are within the range of the pattern vector.

As described above, the measurement by the sensor 20 is received periodically or input when an event occurs, in this case, one environment vector is generated. At this time, it is found whether there is a pattern vector satisfying the values of each element of the generated environment vector. That is, it is determined whether the measured values of each element of the environment vector are within the range of each element of the pattern vector to determine whether they match.

For example, suppose the following environment vector is input.

Environment vector A = (2, 21:00, 0, 30 minutes)

Environment vector B = (2, 21:00, 2, 30 minutes)

The environment vector A matches pattern 3, and the environment vector B does not have a matching pattern (or pattern vector).

The lighting implementer 55 controls the lighting device 30 with the control vector of the pattern vector when the environment vector matches the pattern vector.

In the above example, the environment vector A matches the pattern 3 and controls the control vector (0,0) corresponding to the pattern 3. That is, the power of the lighting device 30 is turned off.

If there is no pattern vector matching the environment vector, the pattern learning unit 56 generates and learns a pattern vector including the environment vector, and obtains a control vector corresponding to the generated pattern vector (hereinafter, generated pattern vector). . In particular, the pattern learning unit 56 uses the environment vector matching the generated pattern vector and the state vector when the environment vector is input as learning data.

In the above example, the environment vector B does not have a matching pattern vector. In this case, the occupant 10 receives a command for controlling the lighting device 30 and configures the command as a control vector. In other words, the state vector is used to make the control vector. In this case, the state vector refers to a lighting device control command or a control state of the lighting device in the current state by the resident 10 control. For example, in the case of the environmental vector B, if the tenant 10 turns on or remains the luminaire 30 with brightness 3, the state vector is (3,0), and the control vector is also (3,0). to be.

As described above, the environment vector not included in the pattern vector and the state vector at that time are accumulated in the database 60 or the learning DB 62 as training data. In particular, it accumulates for a predetermined time (for example, one week, one month, etc.), and analyzes the accumulated learning data to extract a pattern vector and a control vector. At this time, the learning algorithm uses a conventional learning algorithm, for example, a neural network learning algorithm or a probability learning algorithm such as Bayesian.

As shown in FIG. 4A, a pattern 4 may be generated by the learning result.

Next, the pattern learning unit 56, if there is a pattern vector matching the environment vector, but a state vector different from the control vector of the pattern vector is input, divides the element range and divides the pattern vector into at least two pattern vectors. . Particularly, if there is a pattern vector matching the environment vector, but the pattern vector is different from the control vector of the pattern vector, the pattern learning unit 56 learns the pattern vector from the input state vector.

In the environment vector situation as shown in FIG. 4A, the power of the lighting device 30 is turned off, but the occupant 10 turns on the power. In other words, even when the occupant in the bed has a slight movement at 12 am to 7 am, the occupant 10 always turns off the lighting device.

That is, although there is a pattern 4 matching the environment vector, a state vector different from the control vector is input. The state vector at this time is (0,0), that is, a control state in which the power is turned off. In this case, the pattern 4 of FIG. 4A is subdivided and divided into several patterns as shown in FIG. 4b. At 12:00 pm and 7:00 am, power is turned off even if the occupant's movement in bed is 1-2.

Next, the pattern-based emotional lighting method by the pattern-based emotional lighting system according to an embodiment of the present invention will be described with reference to FIG.

As shown in Figure 5, the pattern-based emotional lighting method comprises the steps of (a) constructing an environmental vector (S10); (b) determining whether a pattern vector matching the environment vector exists (S20); (c) controlling the lighting device 30 with the control vector of the pattern vector when there is a matching pattern vector (S30); (d) if the matching pattern vector does not exist, storing the environment vector and the state vector as learning data (S40); And (e) learning by the learning data to generate or update the pattern vector (S50). Additionally, (f) when the control vector of the pattern vector and a different state vector is input, the method may further include storing the environment vector and the state vector as learning data (S60).

The omitted part of the description of the pattern-based emotional lighting method refers to the description of the user pattern-based emotional lighting system described above.

As mentioned above, although the invention made by this inventor was demonstrated concretely according to the said Example, this invention is not limited to the said Example, Of course, a various change is possible in the range which does not deviate from the summary.
