[0001] The present invention relates to an environment control method using a wearable device having a bio-signal measurement function and an IoT function,

The present invention relates to an environmental control method, and more particularly, to a method and apparatus for controlling a wearer's wearer's wearer's body, Audio equipment, TV, and the like, thereby enabling the user to take a comfortable sleep while preventing electric safety accidents and unnecessary power consumption, and in the morning, when the user's brain is awake but is not awake (IoT) function capable of making an environment where the weather can be more easily performed by performing the operation of turning on the lighting device, the audio device, or the coffee maker, And an environment control method using the device.

Today, advances in wireless network technology have made life a lot easier. Almost everything from home appliances such as air conditioners, fans and TVs to cars can be controlled wirelessly. These technological advances are helping to monitor our health as well as for a comfortable life. In addition, this new concept is intended to monitor the user's physical condition and assist in certain activities.

Many people have a habit of listening to music or watching TV before going to bed, sometimes sleeping while listening to music or watching TV. Some people have a habit of increasing volume while listening to music. Falling asleep with loud music can damage your ears while you sleep. In addition, a continuous sound for the ear, a sound from the TV, or a light illuminating the user's surroundings can awaken the user from sleep. Therefore, it would be good if there is a device that smartly senses the user's sleeping state after the user is asleep and automatically turns off the device and the light. It would also be nice if there was a device that could warn people or people around them when they had a nightmare or had a breathing problem (such as sleep apnea) while sleeping.

On the other hand, Japanese Laid-Open Patent Publication No. 10-2012-0051122 (Patent Document 1) discloses a " system for providing a sleeping environment in a ubiquitous sensor network ", and a method for providing a sleeping environment in the ubiquitous center network, A sleep mode is set through a sleep time previously stored in a wireless terminal or a ubiquitous sensor network server; Transmitting the photographed image to a video server, the infrared radiographed camera being selected; Transmitting the image information transmitted to the image server to the ubiquitous sensor network server; The ubiquitous sensor network server compares the previously stored body temperature information with the image information to discriminate a normal range of body temperature; Generating a control signal for controlling a household appliance corresponding to the body temperature; And controlling the home appliances by receiving the control signals and transmitting the operational details of the home appliances to the ubiquitous sensor network server.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, before describing the embodiment of the present invention in earnest, firstly, the sleep of a human being will be described.

FIG. 1 is a diagram showing the autonomic nervous system and its basic functions (functions) of a human, FIG. 2 is a diagram showing heart rate HR and heart beat variation (HRV) in a wakeful state and REM / non-REM sleep state to be.

Referring to Figures 1 and 2, the Autonomic Nervous System (ANS) 100 is responsible for activities related to activities. Sympathetic Nervous System (SNS) 100a controls sympathetic activity such as sports and exercise, while Para-Sympathetic Nervous System (PNS) 100b is responsible for sleep. Several studies have shown that while human heart rate increases during sympathetic activity, heart rate decreases in parasympathetic activity. Therefore, the present invention utilizes this phenomenon of human response to sleep.

There are basically four levels of sleep. It consists of the first stage of Non Rapid Eye Movement (NREM), the second stage of NREM, the third stage of NREM and the Rapid Eye Movement (REM) stage.

The first two stages NREM 1 and 2 are light sleep stages, while the other two stages, the third and the REM stage, are deep sleep stages. Let's take a closer look at these sleeping steps.

NREM Step 1: This step lasts for almost 1 to 10 minutes. At this stage you are asleep lightly or as your body is getting ready to fall asleep. At this stage, you can easily wake up. During this period, when physiological changes occur, such as slowing breathing and normal heartbeat, a decrease in blood pressure and brain temperature occurs.

NREM Step 2: This step lasts about 20 minutes. At this stage, as the heart rate (HR) slows down, body temperature decreases and blood pressure decreases.

NREM Phase 3: This is the transition time from the initial phase to the REM phase. This step generally begins 35 to 45 minutes after the first step. This step is sometimes called the "delta step". If you wake up at this stage because of disturbances, you may lose your sense of direction for a few minutes.

REM Step: This step starts normally after 90 minutes in NREM Step 1. As the name suggests, the eyes move quickly in all directions at this stage. This is basically the deepest sleep time that most of the dreams take place. In addition, this is the time for some people to sleep or wet the bed. At this stage, the person's heart rate increases and even the respiratory rate and heart rhythm are not regular. This is because during this time the SNS activity increases due to the dreaming.

Hereinafter, an environment control method using a wearable device having bio-signal measurement and IoT function according to an embodiment of the present invention will be described based on the above-described sleep-related information.

FIG. 3 is a flowchart illustrating an execution process of an environment control method using a wearable device having bio-signal measurement and IoT functions according to an embodiment of the present invention.

In addition, a device (for example, a wristwatch-type measuring device 410) for recording data on a user's heart rate (HR), body temperature and respiration according to the monitoring and identifying the state of the user using the recorded data (Step S302).

Then, the user's heart rate (HR), respiration and body temperature are monitored, and the data obtained by the monitoring is compared with the data of the trained device to detect the user's sleeping state (i.e., the sleeping state) (step S303).

As shown in FIG. 6, when the HR, the body temperature, and the respiration rate become regular when the user's sleep state, that is, the non-REM step, is compared with the user's past training data, An ES (Environment Switching) operation is performed to transmit a command for controlling the device to the device (step S304). Here, the command for controlling the apparatus may include at least one of turning off the illumination 601, weakening the illumination 601, turning off the TV 602, and turning off the media request. Also, the usable medium may include at least one of Wi-Fi, Bluetooth, and infrared rays.

Preferably, the environment control method using the wearable device having bio-signal measurement and IoT function according to the present invention continuously monitors respiration rate and skin conductivity when the user is in the sleep state, as shown in FIG. 8 Step S801; (S802) of determining whether the user's breathing rate (respiration rate) is stopped for a predetermined time or more (respiratory rate interval is increased more than a predetermined time) in the monitoring process; And a step (S803) in which the user is regarded as sleep apnea if the respiration of the user is interrupted for a certain period of time or longer and the skin conductivity is increased, and warning to the user or warning to another device worn by another person in the area based on the user setting can do. At this time, if the user's breathing is stopped for 10 seconds or longer, it can be regarded as sleep apnea.

Preferably, the environmental control method using the wearable device having the bio-signal measurement and IoT function according to the present invention is performed in a state where the user's brain is awake in the morning, And turning on the audio device or letting the coffee maker lower the coffee.

With an additional module (rocket), you can detect sleep apnea in an important memo device. Sleep apnea is a health problem that can stop people breathing for a certain period of time, which can be very dangerous and can cause serious problems.

Therefore, in addition to detecting sleep and ES (Environment Switching), depending on the configuration of the device, the device will detect the condition of the person during sleep and warn the user, the ES, and, if such a problem occurs, Devices can also be warned. Based on these data settings, you can automatically upload them to the cloud or email them to the email recipients listed in your settings.

&Lt; Solution introduced in the present invention >

Studies have shown that the normal resting heart rate for adults over age 18 is 60 to 80 bits per minute (bpm), but it may be slightly lower for athletes. On the other hand, for children between the ages of 6 and 15, the normal resting heart rate is between 70 and 100 bpm. So, everyone has their average resting heart (heart). In a study conducted by Dr. K Krauchi in "Neuropsychopharmacology" (2001), the average heart rate of 52 bits per minute decreased by about 8% at 64 bits per minute. Other studies show a similar decrease in heart rate during NREM sleep. Studies have shown that body temperature falls during the first stage of sleep and breathing becomes regular.
