6 is a flowchart illustrating a method of controlling a baby cot according to an embodiment of the present invention.

Referring to FIG. 6, in step S1, the baby crib 1 determines the state of the baby using a camera module and a sensor.

Specifically, the baby crib 1 may determine the state of the baby through an image captured by the camera module 110. For example, the baby bed 1 may determine whether a baby is present in the bed body 10, a baby's facial expression, and a baby's posture through the photographed image.

The baby crib 1 may determine the state of the baby through the voice input through the microphone 130. For example, the baby crib 1 may determine whether the baby is crying, breathing, or swaying through the input voice.

The baby crib 1 may determine the state of the baby through the bio-signals measured by the bio-signal detection sensor 150. For example, the baby bed 1 may determine whether a baby is present in the bed body 10, a movement state of the baby, a breathing state, and a posture, etc. through information measured by an optical fiber magnetic sensor. .

In this way, the baby crib 1 may determine the state of the baby by collecting information obtained through the various components described above.

In step S2, the baby crib 1 controls the lighting module based on the determined state of the baby and the current time.

Specifically, the baby crib 1 may control the illuminance or color temperature (light color) of the lighting module 50 according to whether the baby is sleeping or awakening.

Here, the color temperature may be understood as representing the color of the light source as a number using an absolute temperature (kelvin, K). A red light source may have a lower color temperature, and a blue light source may have a higher color temperature.

The baby crib 1 may adjust the color temperature of the lighting module 50 differently based on a sunrise time or a sunset time. In this case, the baby crib 1 may control the color temperature of the lighting module 50 differently according to whether the baby is sleeping or awakening together with the sunrise time or sunset time.

Table 1 below shows the color temperature (K) of lighting based on the time zone and the state of the baby according to the present embodiment.

slot Baby's condition or behavior Color temperature (K) Similar environment Sunrise time-10:00 a.m. N minutes before wake-up time 3000 At sunrise Wake up time 3500 After sunrise/before sunset Morning activity time
(Activity hours after weather) 4000 Sunlight between 10 o'clock and 15 o'clock 10:00 am-sunset time Active time during the day 5500 Noon sunlight N minutes before the nap time 4500 Late afternoon sunlight N minutes before waking up 5000 Broad daylight Nap wake-up time 5500 Noon sunlight Sunset time ~ next day sunrise time Evening activity time 4500 Late afternoon sunlight N minutes before sleep time 3500 After sunrise/before sunset Sleep time 2000 At sunset Woke up during a night's sleep 1700 Matchlight/candle

As shown in Table 1, the baby crib 1 may control the color temperature of the lighting module 50 in consideration of both the current time and the state of the baby.

Here, the baby's wake-up time and bedtime (nap, night sleep) may be set in advance by the user. That is, in the memory of the crib 1, the baby's wake-up time and the scheduled time to sleep may be stored in advance.

7 is a flowchart illustrating a method for determining a baby's state according to an embodiment of the present invention.

Referring to FIG. 7, in step S11, the baby crib 1 captures an image using a camera.

Specifically, the baby bed 1 drives the camera module 110 to control the baby in the bed body 10 to be photographed.

In this case, the camera module 110 may capture not only the baby's face, but also images of arms, legs, abdomen, and around the bed. Accordingly, it is possible to grasp the baby's facial expression, posture, movement, sleep status, and conditions around the bed.

In step S12, the baby crib 1 determines whether or not the face is visible.

Specifically, the baby crib 1 determines whether the baby's face is accurately visible through the image captured by the camera module 110.

For example, the baby crib 1 may compare the baby's face image with a pre-stored face image in the captured image to determine whether the face is accurately visible. That is, by determining an image of the baby's eyes, nose, and mouth from the captured image, and comparing it with a previously stored face image, it may be determined whether or not the face image is included in a certain ratio or more.

If the baby's face is not visible in the captured image, the baby crib 1 determines that the baby's face is covered in step S13.

And in step S28, the crib 1 transmits the determined state of the baby to an external terminal.

Here, the external terminal may include any one or more of a mobile terminal, a PC, a notebook, and an external server possessed by the user.

If the baby's face is visible in the captured image, in step S14, the crib 1 determines whether there is a change in facial expression.

Specifically, the baby crib 1 may determine whether or not there is a change in the baby's facial expression for a predetermined period of time in the captured image. Accordingly, it is possible to determine whether the baby is currently sleeping, awake, or beating.

If there is no change in the baby's facial expression in the captured image, the baby crib 1 determines whether or not there is a movement of the baby in step S15.

The baby crib 1 may determine whether or not the baby's movement has occurred for a certain period of time in the captured image. Here, the baby's movement may mean movement of the baby's head, head, arms, or legs.

When it is determined that there is movement of the baby, it is determined in step S20 whether the baby bed 1 continues to move at a frequent frequency.

For example, when movements with respect to the head, head, arms, or legs occur more than a reference number for a certain period of time, it may be determined that the movement continues at a frequent frequency.

If it is determined that the movement has been continued at a frequent frequency, the crib 1 determines that the baby is awake in step S21, and transmits the baby's state determined in step S28 to an external terminal.

If it is determined that the movement does not continue at a frequent frequency, in step S22, the baby crib 1 determines that the baby is turning while sleeping, and transmits the state of the baby determined in step S28 to an external terminal.

On the other hand, if it is determined that there is no movement of the baby, in step S16, the crib 1 determines whether there is movement of the abdomen.

The baby crib 1 may determine whether or not an abdominal movement has occurred for a certain period of time in the captured image. Through the movement of the abdomen, it is possible to determine whether the baby is currently breathing.

If it is determined that there is abdominal movement, the baby crib 1 determines that the baby has fallen asleep in step S17, and transmits the baby's state determined in step S28 to an external terminal.

If it is determined that the abdominal movement does not exist, in step S18, the baby bed 1 determines whether the abdominal movement has stopped for a predetermined time or longer.

When it is determined that the abdominal movement has stopped for a predetermined time or longer, the baby crib 1 determines that the baby is sleep apnea in step S19, and transmits the baby's state determined in step S28 to an external terminal.

On the other hand, when there is a change in the baby's expression in step S14, it is determined whether the baby crib 1 is a crying expression in step S23.

Specifically, the baby crib 1 may determine whether the baby's expression is a crying expression by comparing the baby's face image with a pre-stored face image in the captured image.

For example, the baby crib 1 may determine whether the baby is crying by comparing an image of the baby's eyes or mouth in the captured image with a pre-stored image (eg, a face image of a crying expression).

When it is determined that the baby's expression is a crying expression, the crib 1 determines that the baby is crying in step S24, and transmits the baby's state determined in step S28 to an external terminal.

If it is determined that the baby's expression is not a crying expression, in step S25, the baby bed 1 determines whether or not the facial expression change continues at a frequent frequency.

For example, when facial expression changes occur more than a reference number of times for a certain period of time, it may be determined that the facial expression changes continue at a frequent frequency.

If it is determined that the facial expression change has continued at a frequent frequency, the baby crib 1 determines that the baby is awake in step S26, and transmits the baby's state determined in step S28 to an external terminal.

If it is determined that the facial expression change does not continue at a frequent frequency, the baby crib 1 determines that the baby is beating in step S27, and transmits the baby's state determined in step S28 to an external terminal.

At this time, the baby crib 1 may photograph the baby's face and transmit it to an external terminal or server when the baby is behaving. Alternatively, the baby crib 1 may store the photographed baby's face in a memory.

In this way, the baby crib 1 may determine various states of the baby through an image captured by a camera. In addition, since the user can quickly receive the determined baby's condition through the camera, there is an effect of taking quick action in case of an emergency or the like.

8 is a flowchart illustrating a method for determining a baby's state according to another embodiment of the present invention.

Referring to FIG. 8, in step S31, the crib 1 detects a sound or sound signal using a microphone.

Specifically, the baby crib 1 controls the microphone 130 to sense the ambient noise (sound signal) of the bed body 10 by driving the microphone 130.

For example, when there is a baby in the bed main body 10, the baby's breathing sound, crying sound, and baboon may be input to the microphone 130.

In the memory of the crib 1, sound signals corresponding to the baby's breathing sound, crying sound, and coot may be stored in advance. Accordingly, the baby crib 1 may determine the state of the baby by comparing the detected sound signal with the sound signal stored in the memory.

In step S32, the baby crib 1 determines whether or not breath sounds are regularly detected.

The baby crib 1 analyzes the sound signal sensed by the microphone 130 to determine whether or not the breath sound is regularly detected for a predetermined period of time.

When it is determined that breathing sounds are regularly detected, the baby crib 1 determines that the baby has fallen asleep in step S33, and transmits the baby's state determined in step S42 to an external terminal.

Here, the external terminal may include any one or more of a mobile terminal, a PC, a notebook, and an external server possessed by the user.

If it is determined that the breathing sound is not regularly detected, the baby crib 1 determines whether or not a crying sound is detected in step S34.

When it is determined that the crying sound is detected, the crib 1 determines that the baby is crying in step S35, and transmits the baby's state determined in step S42 to the external terminal.

If it is determined that the crying sound has not been detected, the baby crib 1 determines whether or not the crib is detected in step S36.

If it is determined that the baboon has been detected, in step S37, the baby crib 1 determines whether the baboon continues at a frequent frequency.

For example, when the baby crib 1 detects a crib more than a reference number for a certain period of time, it may be determined that the crib continues at a frequent frequency.

If it is determined that the coot has continued at a frequent frequency, the baby crib 1 determines that the baby is awake in step S38, and transmits the baby's state determined in step S42 to an external terminal.

If it is determined that the babbling does not persist at a frequent frequency, in step S39, the baby crib 1 determines that the baby is turning while sleeping, and transmits the baby's state determined in step S42 to an external terminal.

On the other hand, when it is determined that the gong has not been detected, in step S40, the baby crib 1 determines whether the breathing sound is not detected for a predetermined time or longer.

For example, the baby crib 1 may determine whether the baby's breathing sound has not been detected for more than 20 seconds.

When it is determined that the breathing sound has not been detected for a predetermined time or longer, the baby crib 1 determines that the baby is sleep apnea in step S41, and transmits the baby's state determined in step S42 to an external terminal.

If it is determined that the breathing sound has been detected, the baby crib 1 may enter step S31 and detect the sound again.

As such, the baby crib 1 may determine various states of the baby through the sound signal sensed by the microphone. In addition, since the user can quickly receive the determined baby's condition through the microphone, there is an effect of taking quick action in case of an emergency or the like.

9 is a flowchart illustrating a method for determining a baby's state according to another embodiment of the present invention.

Referring to FIG. 9, in step S51, the baby crib 1 detects a bio-signal using a bio-signal detection sensor.

Specifically, the baby crib 1 detects a biological signal of a baby by driving the biological signal detection sensor 150.

Here, the biosignal may include a signal related to movement of the human body, a signal related to sleep, a signal related to respiration, and a signal related to a heart rate.

In this embodiment, the biosignal detection sensor 150 may include at least one of an optical fiber magnetic sensor, a motion detection sensor, a pressure sensor, a heart rate sensor, and a weight sensor.

The optical fiber magnetic sensor may calculate a baby's posture and respiratory rate by measuring an impedance change due to a distance between a fiber electrode and a human body. The optical fiber magnetic sensor may be mounted on the mattress 111 to monitor the baby's movement state or breathing state.

The motion detection sensor may include an acceleration sensor and a gyroscope (angular velocity sensor). The motion detection sensor may be mounted on the mattress 111 to monitor a motion state or posture of the baby.

In step S52, the baby crib 1 determines whether or not motion is detected.

For example, the baby crib 1 may detect movement of a baby through a signal input through an optical fiber magnetic sensor.

If it is determined that the movement of the baby has not been detected, in step S53, the crib 1 determines whether or not breathing is detected.

When it is determined that the baby's movement is not detected and breathing is detected, in step S54, the baby crib 1 determines that the baby has fallen asleep, and transmits the baby's state determined in step S61 to an external terminal. .

Here, the external terminal may include any one or more of a mobile terminal, a PC, a notebook, and an external server possessed by the user.

When it is determined that neither movement nor breathing of the baby is detected, the baby bed 1 determines whether breathing is not detected for a predetermined time or longer in step S55.

For example, the baby crib 1 may determine whether a signal generated during the baby's breathing process has not been detected for more than 20 seconds.

When it is determined that the breathing has not been detected for a predetermined time or longer, the baby crib 1 determines that the baby is sleep apnea in step S56, and transmits the baby's state determined in step S61 to an external terminal.

If it is determined that breathing has been detected, the baby crib 1 may enter step S53 to detect breathing again.

On the other hand, if it is determined that the movement of the baby is detected, it is determined in step S57 whether the baby bed 1 continues to move at a frequent frequency.

For example, when movements with respect to the head, head, arms, or legs occur more than a reference number for a certain period of time, it may be determined that the movement continues at a frequent frequency.

If it is determined that the movement does not continue at a frequent frequency, in step S58, the baby crib 1 determines that the baby is turning while sleeping, and transmits the state of the baby determined in step S61 to an external terminal.

If it is determined that the movement has been continued at a frequent frequency, in step S59, the baby crib 1 determines whether the heart rate is at the level of the awakening state.

Here, the heartbeat rate at the level of the arousal state may mean a normal heart rate that is generally sensed while the baby is awake.

If it is determined that the detected heart rate is not the level of the awakening state as a result of the determination, in step S58, the crib 1 determines that the baby is turning while sleeping, and transmits the state of the baby determined in step S62 to an external terminal.

If it is determined that the detected heart rate is the awakening state level, the baby crib 1 determines that the baby is awake in step S60, and transmits the baby's state determined in step S62 to an external terminal.

As such, the baby crib 1 may determine various states of the baby through a bio-signal sensor. In addition, since the user can quickly receive the determined baby's condition through the sensor, there is an effect of taking quick action when an emergency situation occurs.

10 is a flowchart illustrating a method of controlling a baby cot in a first time zone according to an embodiment of the present invention.

Here, the first time zone may mean a time zone from a time before sunrise to noon. The sunrise time may vary depending on the region and season.

However, in this embodiment, the sunrise time is defined as 07 am as an example. The sunrise time may be preset in the memory of the crib 1.

In addition, in the present embodiment, the first time zone will be described as being a time zone between 06 am and 10 am.

Referring to FIG. 10, in step S71, the crib 1 determines whether the baby is in the crib.

Specifically, the baby bed 1 can determine whether the baby is in the bed using at least one of the camera module 110, the microphone 130, and the biosignal detection sensor 150 described above. have.

If the baby does not exist in the bed, the baby crib 1 turns off the lighting in step S72. That is, when the baby is not in the bed, the lighting module 50 may be turned off.

When the baby is in the bed, the baby crib 1 determines whether the sunrise time has passed in step S73.

The baby crib 1 may determine whether the current time is earlier or slower than the sunrise time of 07 am.

If it is determined that the sunrise time has not passed, in step S74, the crib 1 determines whether the baby has awakened.

The baby crib 1 may determine whether or not the baby is awake by using at least one of the camera module 110, the microphone 130, and the biosignal detection sensor 150.

If the baby does not wake up, the baby crib 1 turns off the lighting in step S72.

When the baby wakes up, the baby crib 1 drives the lighting at the first color temperature in step S74.

Specifically, when the baby wakes up before sunrise starts, the baby crib 1 may operate the lighting module 50 at the first color temperature.

Here, the first color temperature may be 1700K (Kelvin).

In other words, when a baby wakes up after sleeping at night, it is possible to provide an optimal sleep environment by providing illumination with the lowest color temperature.

On the other hand, if it is determined that the sunrise time has passed, in step S76, it is determined whether the baby crib 1 remains for N hours until the wake-up time.

The baby crib 1 may compare the current time with a preset wake-up time and calculate the remaining time until the wake-up time. The user can input and set the baby's wake-up time in advance.

For example, the baby crib 1 may determine whether or not about 5 minutes remain until the wake-up time.

If there are not N hours left until the wake-up time, the baby crib 1 may turn off the light in step S72 to help the baby sleep.

That is, when a relatively large amount of time remains until the wake-up time, the baby crib 1 can keep the lighting off.

If the wake-up time remains for N hours, in step S77, the baby crib 1 drives the lighting at the second color temperature until the wake-up time arrives.

Here, the second color temperature may be 3000K.

Specifically, the baby crib 1 may provide an environment similar to when the sun rises in consideration of the upcoming wake-up time of the baby. To this end, the baby crib 1 may provide illumination with brightness at sunrise.

In step S78, the baby crib 1 determines whether or not the set wake-up time arrives, and when the wake-up time arrives, drives the lighting to the third color temperature in step S79.

Here, the third color temperature may be 3500K.

The baby crib 1 may provide an environment similar to the sunrise time when the wake-up time arrives. To this end, the baby crib 1 may provide illumination at the brightness of sunlight after sunrise.

In step S80, the baby crib 1 determines whether the baby has awakened from sleep, and when the baby is awakened as a result of the determination, in step S81, the lighting is driven at a fourth color temperature.

Here, the fourth color temperature may be 4000K.

The baby crib 1 provides comfortable lighting for morning activities when the baby wakes up while providing illumination with the brightness of sunlight at sunrise. That is, the baby crib 1 may provide illumination with a brightness corresponding to sunlight between 10 am and 3 pm.

According to the configuration of the present invention, there is an effect of creating a wake-up environment so that the baby wakes up naturally at a set wake-up time. In addition, after the baby wakes up, it can have a good effect on the baby's body rhythm by providing a comfortable light for the baby to be active.

11 is a flowchart illustrating a method of controlling a baby cot in a second time zone according to an embodiment of the present invention.

Here, the second time zone may mean a time zone between noon and before sunset begins. The sunset time may vary by region and season.

However, in this embodiment, the sunset time is defined as 19:00 pm as an example. The sunset time may be preset in the memory of the crib 1.

In addition, in the present embodiment, the second time zone will be described as being a time zone between noon and 18:00 pm.

Referring to FIG. 11, in step S91, the crib 1 determines whether or not the baby is in the crib.

Specifically, the baby bed 1 can determine whether the baby is in the bed using at least one of the camera module 110, the microphone 130, and the biosignal detection sensor 150 described above. have.

If the baby does not exist in the crib, the crib 1 turns off the illumination in step S92. That is, when the baby is not in the bed, the lighting module 50 may be turned off.

When the baby is in the bed, the baby crib 1 determines whether the baby has fallen asleep in step S93.

The baby crib 1 may determine whether the baby has fallen asleep using at least one of the camera module 110, the microphone 130, and the biometric signal detection sensor 150.

When the baby has not fallen asleep, it is determined in step S94 whether the baby crib 1 remains for N hours until the nap time.

The baby crib 1 may compare the current time with a preset nap time and calculate the remaining time until the nap time. The user can pre-enter and set the baby's nap schedule time.

For example, the baby crib 1 may determine whether or not about 5 minutes remain until the nap time.

If there are no N hours left until the nap time, the baby crib 1 drives the lighting at the seventh color temperature in step S95.

Here, the seventh color temperature may be 5500K.

That is, when the current time is significantly earlier than the nap time, lighting is provided at the brightness of noon to provide pleasant lighting for afternoon activities.

If N hours remain until the nap time, the baby crib 1 drives the lighting at the fifth color temperature in step S96.

Here, the fifth color temperature may be 4500K.

When the baby crib 1 remains for N hours until the nap time, it is possible to induce sleep of the baby by providing illumination with the brightness of sunlight in the late afternoon.

Then, in step S97, the crib 1 determines whether the baby has fallen asleep.

As a result of the determination, if the baby has fallen asleep, in step S98, the baby crib 1 gradually decreases the brightness of the lighting for a certain period of time, and turns off the lighting in step S99.

On the other hand, when it is determined in step S93 that the baby is asleep, in step S100, the crib 1 determines whether the current time is before the sunset time.

The baby crib 1 may determine whether the current time is earlier or slower than 19:00 pm, which is the sunset time.

If the current time is after the sunset time, the baby crib 1 turns off the illumination in step S92.

If the current time is before the sunset time, in step S101, it is determined whether the baby crib 1 remains for N hours until the wake-up time.

The baby crib 1 may compare the current time with a preset nap wake-up time and calculate the remaining time until the nap wake-up time.

The nap wake-up time may be preset in the memory of the crib 1. The user can input and set the baby's nap wake-up time.

For example, the baby crib 1 may determine whether or not about 5 minutes remain until the time of waking up for a nap.

If there are not N hours left until the nap wake-up time, the baby crib 1 may turn off the light in step S92 to help the baby sleep.

If the nap wake-up time remains for N hours, in step S102, the baby crib 1 drives the lighting at the sixth color temperature until the nap wake-up time arrives.

Here, the sixth color temperature may be 5000K.

Specifically, the baby crib 1 may provide an environment similar to broad daylight in consideration of the upcoming wake-up time of a baby's nap. To this end, the baby crib 1 may provide illumination with the brightness of sunlight in broad daylight.

In step S103, the baby crib 1 determines whether or not the set wake-up time arrives, and when the wake-up time arrives, drives the lighting at the seventh color temperature in step S104.

Here, the seventh color temperature may be 5500K.

When the wake-up time arrives, the baby crib 1 may provide illumination with the brightness of sunlight at noon for a certain period of time.

That is, when the time for the baby to wake up comes, the lights can be brightened to induce the baby's awakening.

In step S105, the crib 1 determines whether the baby has awakened, and when awakening, in step S106, the crib 1 maintains the current color temperature.

If the baby does not wake up even when the lighting is activated for a certain period of time, the baby crib 1 may go to step S98 to reduce the brightness of the lighting for a certain period of time, and then turn off the lighting.

According to the configuration of the present invention, there is an effect of creating a sleeping environment so that the baby can sleep at the scheduled nap time, and creating a wake-up environment so that the baby can wake up naturally at the nap wake-up time.

12 is a flowchart illustrating a method of controlling a baby cot in a third time zone according to an embodiment of the present invention, and FIG. 13 is a view showing a screen of a mobile terminal according to an embodiment of the present invention.

Here, the third time zone may mean a time zone between a time when sunset starts and before sunrise starts the next day. The sunset and sunrise times may differ depending on the region and season.

However, in this embodiment, the sunset time is defined as 19:00 pm as an example. The sunset time may be preset in the memory of the crib 1.

In addition, in the present embodiment, the third time zone will be described as being a time zone between 18 pm and 6 am the next day.

Referring to FIG. 12, in step S111, the crib 1 determines whether the baby is in the crib.

Specifically, the baby bed 1 can determine whether the baby is in the bed using at least one of the camera module 110, the microphone 130, and the biosignal detection sensor 150 described above. have.

If the baby does not exist in the bed, the baby crib 1 turns off the lighting in step S112. That is, when the baby is not in the bed, the lighting module 50 may be turned off.

When the baby is in the bed, the baby crib 1 determines whether the baby is awake in step S133.

The baby crib 1 may determine whether the baby is awake using at least one of the camera module 110, the microphone 130, and the biosignal detection sensor 150.

When the baby is not awake, that is, when the baby is asleep, the baby crib 1 turns off the lighting in step S112.

When the baby is awake, the baby crib 1 determines whether the sunset time has passed in step S114.

If the sunset time has not passed, the baby crib 1 drives the lighting at the fifth color temperature in step S115.

Here, the fifth color temperature may be 4500K.

When it is determined that the current time is a time before the sunset time, the baby crib 1 may provide illumination with the brightness of sunlight in the late afternoon. That is, the baby can provide pleasant lighting for afternoon activities.

If the sunset time has elapsed, it is determined in step S116 whether or not the baby crib 1 remains for N hours until a moment at night.

The baby crib 1 may compare the current time with a preset night sleep schedule time, and calculate the remaining time until the night sleep schedule time. The user can pre-enter and set the baby's scheduled time to sleep at night.

As an example, the baby crib 1 may determine whether or not about 20 minutes remain until the scheduled time to sleep at night.

If there are no remaining N hours until a moment at night, the baby crib 1 drives the lighting at the fifth color temperature in step S115.

That is, when a relatively large amount of time remains until a moment at night after the sunset time has elapsed, the baby crib 1 may provide illumination with the brightness of sunlight in the late afternoon.

If, in the case of N hours remaining until the moment of the night, in step S117, the baby crib 1 drives the lighting at the third color temperature until the moment of the night arrives.

Here, the third color temperature may be 3500K.

When the baby's crib 1 approaches the scheduled time of sleep at night, the baby's sleep can be induced by providing lighting with a relatively low color temperature.

At this time, the baby crib 1 may transmit a notification of the scheduled night sleep time to an external terminal when the current time is close to the scheduled night sleep time.

For example, as shown in FIG. 13, the baby crib 1 may transmit a notification 61 to the user's mobile terminal 60 in a situation where 20 minutes remain until the scheduled time for a night sleep. Therefore, the user can check the sleeping time of the baby in advance.

In step S118, the baby crib 1 determines whether or not the set temporary night time arrives, and when the set temporary night time arrives, in step S119, the lighting is driven at the eighth color temperature.

Here, the eighth color temperature may be 2000K.

The baby crib 1 may provide illumination with the brightness of sunlight at sunset when a temporary night arrives. That is, the baby crib 1 can further promote sleep induction of the baby when the sleep time arrives.

In step S120, the baby crib 1 determines whether the baby has fallen asleep. And when the baby is asleep, the baby crib 1 in step S121 gradually decreases the lighting brightness for a certain period of time, and turns off the lighting in step S122.

Subsequently, in step S121, the baby crib 1 determines whether the baby has awakened from sleep, and when the baby is awakened as a result of the determination, in step S124, the light is driven to the first color temperature.

Specifically, when a sleeping baby wakes up, the baby crib 1 may operate the lighting module 50 at a first color temperature.

Here, the first color temperature may be 1700K.

In other words, when a baby wakes up after sleeping at night, it is possible to provide an optimal sleeping environment so that the baby can fall asleep again by providing lighting with the lowest color temperature.

According to the configuration of the present invention, there is an effect of creating a sleeping environment so that the baby can sleep at the scheduled time of sleep at night, and inducing the baby to fall asleep again when awakening.

14 is a diagram showing analyzed sleep data according to an embodiment of the present invention.

Referring to FIG. 14, the baby crib 1 may acquire baby's sleep data using at least one of the camera module 110, the microphone 130, and the bio-signal detection sensor 150 described above. have.

That is, the baby crib 1 may acquire and accumulate sleep data such as a baby's sleeping time, awakening time while sleeping, or the number of turns while sleeping. In addition, the baby crib 1 may be statistically analyzed by analyzing the acquired sleep data.

The baby crib 1 may provide the analyzed sleep data to the mobile terminal 60 connected to communication or an external server. In addition, the mobile terminal 60 or an external server may reprocess and statistics the provided sleep data.

Meanwhile, on the display of the mobile terminal 60, information on recorded parenting activities may be displayed. The mobile terminal 60 may receive information on parenting activities from the baby bed 1 or an external server.

Specifically, on the display of the mobile terminal 60, various activity records related to child-rearing, such as lactation, sleep, bowel movements, and going out, may be displayed as graphs or characters.

An analysis result screen in which recorded parenting activities are displayed as statistics according to a predetermined period may be displayed on the display. For example, on the analysis result screen, a period selection button 62 for statistically showing recorded parenting activities on a daily, weekly, or monthly basis may be displayed.

In addition, the recorded parenting activity may be displayed as a graph 64 on the analysis result screen. On the graph 64, sleep, lactation, bowel movements, and outings may be divided and displayed by time slot.

For example, the graph 64 may be formed in a donut or circular shape, and portions corresponding to sleep, lactation, bowel movements, and going out may be displayed in different colors to be distinguished from each other.

In addition, the analysis result screen may include category information 631, 632, 633, and 634 for selecting and highlighting one type of parenting records included in the graph 64.

The category information 631,632,633, 634 may include a lactation category 631, a sleep category 632, a bowel movement category 633, and an outing category 634.

For example, when the sleep category 632 is selected, activities related to sleep in the graph 64 may be highlighted or displayed separately. Conversely, activities for the remaining categories 631, 633, and 634 that are not selected may be dimmed.

Accordingly, the user can grasp all parenting activities that have occurred per day at a glance, and can easily know the frequency and time of parenting activities to be checked.

In particular, the baby crib 1 or the mobile terminal 60 may analyze sleep data to recommend a nap or night sleep schedule, or notify a user when a scheduled nap time or a scheduled night sleep time is close.

For example, if the nap time made today is relatively shorter than the nap time made on the previous day, a phrase 65 such as "Please increase the nap time" may be displayed.
