If it is determined that the baby is present in the bed body 10, in step S40, the control unit 190 turns on the lighting unit 120.

In step S50, the control unit 190 determines whether it is a sleep time.

Specifically, the memory 140 may store a baby's sleeping time and a wake-up time in advance. In this case, a plurality of the sleeping time or the wake-up time may be stored. That is, the user may register and store the baby's sleeping time and waking time in the memory 140.

The controller 190 may determine whether the current time is included in a preset sleep time. Alternatively, the control unit 190 may determine whether the time at which the lighting unit 120 is turned on is included in a preset sleep time.

If it is determined that the current time is not included in the sleeping time, in step S60, the control unit 190 adjusts the brightness of the lighting according to the ambient illuminance.

That is, when it is not time for the baby to sleep, the control unit 190 detects the ambient illumination through the illumination sensor 150 and sets the brightness of the illumination unit 120 according to the detected ambient illumination.

If it is determined that the current time belongs to the sleep time, in step S70, the control unit 190 controls to lower the brightness of the lighting.

That is, when it is determined that it is time for the baby to sleep, the controller 190 may induce sleep of the baby by lowering the brightness of the lighting unit 120 by a predetermined value.

And in steps S80 and S90, the controller 190 detects the state of the baby and determines whether the baby is asleep.

For example, the controller 190 may analyze the image obtained by the camera module 110 to determine whether the baby's facial expression, posture, movement, or sleep.

Alternatively, the controller 190 may determine whether the baby is asleep by using the heart rate sensor 160 or the motion sensor 170 connected to the bed body 10.

When the baby does not fall asleep, in step S100, the controller 190 may maintain the current brightness of the lighting.

When the baby falls asleep, in step S110, the controller 190 gradually reduces the brightness of the lighting for a predetermined time, and in step S120, the controller 190 may turn off the lighting until the wake-up time arrives.

In other words, when the baby is asleep, the light is not turned off immediately, and the brightness of the light is gradually lowered to prevent the baby from waking.

Alternatively, when the baby is asleep, step S110 may be omitted, and step S120 may be performed immediately.

In step S130, the controller 190 may determine whether the baby is awake. That is, the control unit 190 may determine whether the baby is not in a sleeping state through the camera module 110.

If it is determined that the baby is awakened, in step S140, the controller 190 may turn on the lighting, and then repeat step S70 described above.

In this case, the control unit 190 may transmit to an external device that the baby is awake. That is, when the baby wakes up, the user's terminal communicated with the baby crib 1 can immediately check the baby's condition.

If it is determined that the baby has not awakened, in step S150, the controller 190 determines whether the current time arrives at a preset wake-up time.

When the wake-up time does not arrive, the control unit 190 may repeat step S120 described above.

When the wake-up time arrives, in step S160, the control unit 190 may increase the brightness of the illumination step by step for a predetermined period of time.

That is, even if the baby does not currently wake up, when the time to wake up comes, the controller 190 turns on the lighting unit 120 to induce the baby to wake up.

In this case, the control unit 190 may turn on while gradually increasing the brightness of the lighting unit 120 so that the baby can wake up naturally.

Alternatively, when the baby wakes up, the control unit 190 may immediately turn on the lighting unit 120 with a set brightness.

11 is a perspective view of a baby cot according to another embodiment of the present invention, and FIG. 12 is a view showing a state in which a child is sitting in a baby cot according to another embodiment of the present invention.

This embodiment is the same as the previous embodiment in other parts, but is characterized in that there is a difference in the bed cover. Therefore, hereinafter, only the characteristic parts of the present embodiment will be described, and the same parts as the previous embodiment will be used.

11 and 12, a baby crib 1 according to the present embodiment includes a bed body 10.

The bed body 10 may include a bed base 11 and a bed cover 12.

The bed base 11 and the bed cover 12 may be detachably coupled to each other. The bed cover 12 is seated on the bed base 11.

In particular, the bed cover 12 according to the present embodiment is configured so that the bed can function as a sofa or a chair. That is, the bed cover 12 may be coupled to the upper portion of the bed base 11 to open the side of the bed body 10.

The bed cover 12 may be formed to extend upward along the edge of the upper surface of the bed base 11. Accordingly, the bed body 10 may be configured such that a person or child can sit on the bed base 11 through the side surface of the bed body 10.

The bed base 11 may have a flat top surface so that a child can sit. In addition, the bed base 11 may include a mattress 111 formed of a soft material.

The baby crib 1 includes a pole 20 coupled to the bed body 10 and a monitoring device 30 coupled to the pole 20. The pole 20 and the monitoring device 30 may be coupled to one side of the bed cover 12.

Since the pole 20 and the monitoring device 30 have the same structure as the previously described embodiment, a detailed description thereof will be omitted.

The baby bed 1 may include a bed leg 40 coupled to the bed body 10.

The bed leg 40 supports the bed body 10 to be spaced apart from the ground. The bed leg 40 may be formed in a plurality, and may be detachably coupled to the bed base 11.

However, in this embodiment, the bed body 10 may be spaced apart from the ground at a relatively low height so that the bed body 10 functions as a sofa or a chair.

Hereinafter, a method of controlling a baby cot according to another exemplary embodiment will be described in detail with reference to the drawings.

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

The baby crib 1 according to the present embodiment is characterized in that, when it is determined that the child sits on the bed or exists, the monitoring device 30 is controlled accordingly.

Referring to FIG. 13, in step S210, the baby crib 10 or the control unit 190 detects an object (person) placed on the bed.

Specifically, the control unit 190 is placed on the bed body 10 through at least one of the above-described heart rate sensor 160, motion sensor 170, weight sensor 180, and image sensor (camera module). Objects (people) can be detected.

For example, the heart rate sensor 160 may be installed inside the bed body 10 to detect the heart rate of a person sitting in the bed body 10.

The motion sensor 170 is installed in the bed body 10 and may detect a movement of a person sitting in the bed body 10.

The weight sensor 180 is installed above the bed body 10 to detect the weight of a person sitting on the bed body 10.

In step S220, the control unit 190 determines whether or not the object is placed on the bed for a predetermined time or longer.

Specifically, in order to determine whether the child sits or stays on the bed body 10, the control unit 190 may detect an object placed on the bed for a predetermined time or longer.

If it is determined that the object has not been placed on the bed for a predetermined time or longer, in step S230, the controller 190 may turn off the lighting.

If it is determined that the object has been placed on the bed for a predetermined time or longer, in step S240, the controller 190 may turn on the lighting.

In step S250, the control unit 190 may rotate the lighting unit so that the lighting faces the object.

Specifically, in the initial state, the camera module 110 is disposed to face downwards of the bed body 10 for monitoring of the baby, and the lighting unit 120 is disposed to face upwards of the bed body 10 Can be.

In this case, since the lighting unit 120 faces upward, the amount of light for reading may be insufficient. Therefore, when a child sits on a bed for reading, it is necessary to illuminate the light to face the child. To this end, the controller 190 rotates the monitoring device 30 to control the lighting to face the child.

Then, the lighting unit 120 may be disposed to face downwards of the bed body 10, and the camera module 110 may be disposed to face upwards of the bed body 10.

In addition, in step S260, the control unit 190 may adjust the brightness of the lighting according to the ambient illuminance.

For example, when the child sits on a bed, the control unit 190 may control the brightness of the lighting to provide lighting that is advantageous for reading. In this case, the control unit 190 may control the lighting unit 120 to operate with an illuminance brighter than the ambient illuminance.

Alternatively, the controller 190 may control the lighting unit 120 to operate with a preset illuminance or an illuminance desired by a user.

In step S270, the control unit 190 may determine whether the object disappears from the bed. That is, the control unit 190 may determine whether the child sitting on the bed has left the seat.

Specifically, the controller 190 may determine whether the child has moved from the bed to another place through at least one of the heart rate sensor 160, the motion sensor 170, and the weight sensor 180.

However, since the camera module 110 faces upward of the baby crib 1, the movement of the child cannot be detected through the image sensor.

When the object does not disappear from the bed, the control unit 190 may continue to maintain the current brightness of the lighting.

If the object disappears from the bed, in step S280, the controller 190 may turn off the lighting.

And in step S290, the control unit 190 may rotate the lighting unit 120 to its original position. That is, the control unit 190 may rotate the lighting unit 120 to face upward of the bed body 10.
