[0001] CONTROL OF SMART LAMP BASED ON BIORHYTHM ANALYSIS [0002]

The present invention relates to a smart lighting control technique, and more particularly, to a smart lighting control technique for controlling lighting according to user's emotions using smart phones and biorhythm analysis.

Light is an important element that can not be missed in human life. For this reason, the interior is supplied with light through the lighting. There is one in each room at home, and it can be easily found in all places such as restaurants, public transportation, and schools. The light that comes into close contact with this is almost life-span. It is used to decorate the inside of the building using the lighting by using such a point. There is a method of decorating the shape of the lighting itself, but it also gives various expressions by paying attention to color and illumination. With this perspective in mind, smart lighting will be able to control and control the emotions of users themselves.

Currently, smart lights can be turned on and off by the user using a smartphone, and only passive methods such as directly changing the color or adjusting the brightness are commercially available.

'Emotion Lamp' allows users to set the desired color or illumination directly by using the basic functions of smart light, which is currently commercialized, and complements the current emotion without direct control by utilizing the user's biorhythm, And provides color and illumination that can be maximized through illumination.

The smart lighting technology that has been proposed in the past is briefly described.

Philips' Hue is a typical smart light that allows you to adjust the illumination and 16 million colors of your smartphone, especially if you have color control, but you can take your favorite colors or take photos from your smartphone, It can also be expressed. You can also set the time to turn on and off the lights. In addition, if the user speaks in the language set in the Hue related application, the designated operation is executed and the user can use the program more conveniently.

Xiaomi's Yee Light, like Hue, is a typical smart light that can be turned on and off with a smartphone and its illumination can be adjusted. The basic colors such as hot pink, blue, green, orange, and red are combined to total 16 million colors. In addition, color control and brightness control can be controlled in the lighting itself. Compared to Hue, the illuminated lighting control application does not have many functions and shows a simple structure.

LG Electronics' smart lamp is the result of the introduction of smart bulb among Korean companies for the first time. Basically, like the previous two smart lights, you can turn on and off the light through the mobile application and adjust the brightness of the light, but it does not have the ability to display color on the light bulb. Another difference is that there are several modes in the lighting control application. It is possible to produce various moods for each mode by adjusting brightness in each of 9 modes such as a weather mode, a reading mode, and a play mode.

On the other hand, biorhythm is a constant phenomenon in which the body, emotion, and intellect are periodically repeated with a cycle of 23 days, 28 days, and 33 days, respectively. Recently, biorhythm has been used to improve the prevention and efficiency of industrial accidents, and it has been used in a wide range of fields such as to control conditions of athletes.

Although various smart lights have been developed in this way, conventional lights are merely a simple control and manipulation through a mobile application, and in particular, there is no technology capable of automatically controlling according to a user's emotions through biorhythm analysis .

According to the present invention, not only the emotion of the user itself is used, but also the external factors that affect the emotion of the user are reflected to control the illumination. That is, it affects the body index, uses weather data, which affects the user's daily routine, and public data such as fine dust and disaster information. When there are alarms or specials, we provide red light notification service, and mobile service provides PUSH notification service. It is a service that provides emotional lighting by analyzing the life patterns and environmental changes associated with my biorhythm. Weather and disaster information is data that is referenced to provide a more objective numerical representation of the user's environment, which is expected to be useful data as objective data when providing services at various angles.

Hereinafter, actual embodiments of the present invention will be described.

1. Development Environment

The development environment of the 'Emotion Lamp' of the present invention is as follows. The server was built using the Node.js Express Framework on a Linux Ubuntu server. Database consists of server and mobile internal database, server database is Mysql, mobile is SQLite and Sugar ORM library. The mobile communication module uses the Retrofit 2.0 library, and the algorithm running in the server is implemented in Javascript. Install the Android SDK to build a mobile application and apply it to Galaxy Note using Android 4.1.

2. Client Implementation

2-1. Bluetooth connection

It is a function that the lighting bluetooth module and the mobile application are linked [5] to control the lighting. In order to link the lighting and Bluetooth, the mobile's Bluetooth function must be turned on. When the search is completed on the mobile, it is uploaded to the connectable list. Provides bright white lighting when linked with uploaded lighting.

Let the Bluetooth device connect the client socket and the server socket via UUID to the required value in the socket object used to send and receive data [6]. When the connection is completed, automatic and manual control of the corresponding lighting can be enabled via the mobile, which provides a basis for providing various services through communication with the server.

In the present invention, it is possible to automatically reduce the hassle of manual operation by the user by automatically connecting within the range of Bluetooth, not through the manual connection of Bluetooth for the existing lighting control, and to provide a lighting service automatically when the user is exposed to an environment suitable for using the lighting So that the user is provided with the corresponding lighting service by enhancing convenience and practicality. 4 shows a UUID code for Bluetooth interworking.

Mobile is an intermediary role between server and lamp, and it is the most basic environment for research and development.

User information is input to analyze the biorhythm. When accessing the application for the first time, the user must input user information in the main screen to receive emotional lighting. The inputted user information is stored in the mobile internal DB to be displayed in the environment setting, and is transmitted to the server at the time of initial input and modification to calculate the biorhythm. In addition, you can turn PUSH alarms, weather information alarms, etc. on and off, as well as the pedometer function used to collect activity information.

2-2. Collect distance and physical activity information

The distance traveled by the user during the day is measured in the same manner as the conventional pedometer. Using the acceleration sensor, which is one of the most popular sensors of the smartphone, the coordinate values are calculated, and the values are received. This value is used to calculate the distance and the amount of activity in a day and transmit it to the server to analyze the biorhythm. Collects the activity information of the user from time to time and recognizes the current state of the user when the activity exceeds the predetermined standard. The collected distance and activity (gait) information is reflected in the biorhythm body index. FIG. 5 shows an acceleration sensor code for collecting man-month data.

2-3. Provide biorhythm lighting

The calculated biorhythm information includes weather information such as temperature and humidity, fine dust concentration, and the value of the number of steps of walking, thereby providing biorhythm lighting suitable for the user. At this time, the biorhythm is divided into high-level and low-level for each body, emotion, and intelligence to subdivide the recommended lighting for the user. Table 1 and FIG. 6 show that the body part of the biorhythm decreases according to the change in the number of steps, and shows that the biorhythm illumination changes accordingly.

3. Server implementation

When the user first launches the mobile application, or when the user's mobile is paired with the lighting and Bluetooth, the client automatically requests the server for the biorhythm information. The server analyzes the biorhythm using the user's date of birth, activity, current weather and fine dust based on the contents of the request, and provides the result to the client.

3-1. User information management

userinfo name cell year month day

<User information DB>

In future, the server stores and manages user information when the user purchases a new device, reloads the service, and prepares for preventing duplication. The user information collected by the server is the biorhythm-related information required for the initial login and the mobile phone number and birth information for user identification. You will be asked to log in again or check your mobile phone number for duplicate check. Also, the birth date information of the user, which is birth information, is also used in the process of calculating the biorhythm.

3-2. Collecting public data portal wait information

To calculate the biorhythm, the client requests weather information from the server. The server receiving the request from the client uses the request module to access the air pollution information service of the public data portal and receive the necessary information. After obtaining the result, the server re-routes to the redirect. Based on the air pollution information, the rerouted server will parse the local forecast RSS information provided by the Korea Meteorological Administration. All information is processed in JSON format, and the weather information extracted only the necessary information is sent to the biorhythm algorithm. Table 3 shows the waiting information gathering code.

3-3. Biorhythm algorithm

The user's date of birth, air pollution information, weather information, and activity amount are used to calculate the biorhythm. The user's date of birth is selected by comparing the received mobile phone number information with the DB, and other information is received from the client.

The user's date of birth and the reference date are used to calculate the total date the user has lived that day. Using the calculated total date, the biorhythm index is made at a cycle that matches the body, emotion, and intelligence. This index uses air pollution information, weather information, and activity information to perform additional calculations. Each information affects only the body and emotion except intelligence.

The calculated biorhythm information is responded to the client in JSON format. Based on the additional calculated information, it is once again routed to provide the recommended lighting information.

 Table 4 illustrates the biorhythm algorithm code.

As described above, according to the present invention, automatic control of lighting according to a user's physical condition, emotion, and intelligence index is proposed by an automatic lighting control application using a biorhythm. In particular, we focused on the color therapy effect by analyzing the user 's biorhythm and suggesting the illumination color accordingly. In addition, it extracts the weather, fine dust, and travel distance information that affect the physical condition of the user, leaving the non-scientific biorhythm, and analyzes the biometric information closely related to the physical condition of the actual user. This suggests a color that illuminates the biorhythm of the current user and mitigates or elevates it to help control the emotional state beyond simple mental and physical stability. Also, by checking the analyzed biorhythm on a graph, you can check your current status, next day biorhythm, and past biorhythm. The user can conveniently control the smart lighting by using the service, and the color illumination provided on the basis of the biorhythm analysis can provide effects such as mind and body stability, health care, and accident prevention.
