The folding part 22 is formed in a vertical direction and is connected to the fixing part 21. The folding part 22 may be connected to the upper end of the fixing part 21 by the hinge part 23.

The folding part 22 may be bent or folded at a predetermined angle with respect to the fixing part 21 by the hinge part 23. The folding part 22 may be folded in an outer direction of the bed body 10 with respect to the central axis C1 of the fixing part 21.

For example, the folding part 22 may be folded by 90 degrees in an outward direction of the bed body 10. That is, when the folding part 22 is folded, the monitoring device 30 may be located on the outer side of the bed body 10.

The fixing part 21 and the folding part 22 may have the same diameter. However, in consideration of the installation height of the monitoring device 30, the length of the folding part 22 in the vertical direction may be longer than the length of the fixing part 21 in the vertical direction.

However, the present invention is not limited thereto, and the length (height) of the fixing part 21 may be greater than or equal to the length (height) of the folding part 22.

The pole 20 may include a protrusion 221 for connecting the monitoring device 30.

The protrusion 221 may be formed to protrude from the outer peripheral surface of the pole 20. The protrusion 221 may extend to incline upward at a point on the outer peripheral surface of the pole 20. The reason for this is to facilitate entry and exit of the baby in the bed body 10 and to maximize the shooting angle (range) of the camera module 32.

Accordingly, the protrusion 221 is preferably located at a point adjacent to the upper end of the pole 20.

In this embodiment, an angle formed by the protruding portion 221 and the folding portion 22 may be 90 degrees to 120 degrees. In other words, an angle between the pole 20 and the monitoring device 30 may be 90 degrees to 120 degrees.

In particular, the connection part 37 may be hinged to the protruding part 221 to be folded.

Specifically, a hinge portion 223 is provided inside the protrusion portion 221, and the connection portion 37 may be coupled to the hinge portion 225. Accordingly, the connection part 37 can be moved or folded in a vertical direction within a limited angular range.

The connection part 37 may be rotated (folded) in a rotation angle range of 20 degrees to 25 degrees with respect to the protrusion part 221.

The protrusion 221 may be formed in a hollow shape to connect the electric wire inside the folding portion 22 to the electric wire inside the frame 31 and the connection portion 37.

The pole 20 may include an operation switch 222 for controlling the LED 35 of the monitoring device 30.

The operation switch 222 may be understood as a switch for turning on or off the power of the LED 35. The operation switch 222 may be disposed above the pole 20. As an example, the manipulation switch 222 is provided on the upper end of the folding part 22 and may be operated by a touch or a pressure type.

The operation switch 222 may control the brightness of the LED 35 as well as power on or off the LED 35.

For example, when the control switch 222 is first selected, the power of the LED 35 is turned on, the brightness of the LED 35 is switched to “weak”, and when the control switch 222 is selected twice, The brightness of the LED 35 may be switched to "medium".

In addition, when the operation switch 222 is selected three times, the brightness of the LED 35 is switched to "strong", and when the operation switch 222 is selected four times, the power of the LED 35 can be turned off. have.

By the configuration of the operation switch 222, the user can easily manipulate the brightness of illumination as well as on or off the LED 35.

Specifically, the camera module 110 may be a device for photographing and monitoring a baby in the bed body 10. The camera module 110 may be understood as a concept including the camera module 32 described above.

The camera module 110 may be controlled by a controller 170 to be described later, and captured data may be provided to the controller 170.

The lighting unit 120 functions to diffuse or softly reflect light into the indoor space in which the bed body 10 is located. The lighting unit 120 may include the LED 35 and the diffusion cover 36 described above. The lighting unit 120 may be controlled by a control unit 170 to be described later.

The communication unit 130 may be understood as a configuration for communicating and connecting the baby crib 1 with an external device. Here, the external device may include, for example, various electronic devices such as a terminal, a notebook computer, and a PC. In addition, the external device may include an external server or a cloud.

The communication unit 130 may be connected to an external device by wireless or wired communication. The communication unit 130 may include a communication module for wireless or wired communication.

The weight detection sensor 140 functions to detect the weight of an object or a baby in the bed body 10. The weight detection sensor 140 may be installed on the upper surface of the bed base 11 or around the mattress 111.

For example, when a baby lies or sits on the bed body 10, the weight detection sensor 140 may provide information obtained by sensing the weight of the baby to the control unit 170.

The motion sensor 150 functions to detect the movement of the baby in the bed body 10. The motion sensor 150 may include an acceleration sensor and a gyroscope (angular velocity sensor).

The motion sensor 150 may be installed on the top surface of the bed base 11 or around the mattress 111. The information acquired by the motion sensor 150 is provided to the control unit 170 to determine whether the baby is moving and the degree of movement.

The heart rate sensor 160 functions to detect the baby's heart rate in the bed body 10. The heart rate sensor 160 may be provided inside the bed body 10. For example, the heart rate sensor 160 may be installed on the top surface of the bed base 11 or around the mattress 111.

The control unit 170 controls the overall function of the baby crib 1. The control unit 170 may measure body information including the height and weight of the baby through the camera module 110 and the weight sensor 140. The control unit 170 may transmit the measured information to a server or a mobile terminal.

Hereinafter, a control method for the baby crib 1 to measure body information of a baby will be described in detail with reference to the drawings.

9 is a flow chart showing a method of controlling a baby cot according to an embodiment of the present invention, FIG. 10 is a view showing a screen of a mobile terminal according to an embodiment of the present invention, and FIG. 11 is a flowchart illustrating an embodiment of the present invention. Is a diagram showing the analyzed growth data according to

First, referring to FIG. 9, in step S1, the baby crib 1 turns on the camera module. For example, when the power of the baby crib 1 is turned on, the power of the camera module 110 may be turned on together.

Alternatively, when detecting that the baby is placed on the bed body 10, the camera module 110 may be powered on. The presence of the baby on the bed body 10 may be detected through at least one of the weight sensor 140, the motion sensor 150, and the heart rate sensor 160.

In step S2, the baby crib 1 checks the sleeping state of the baby, and determines whether the baby has fallen asleep in step S3.

Specifically, the baby bed 1 may determine the sleeping state of the baby in the bed body 10 through the camera module 110.

The baby crib 1 may check the baby's facial expression, posture, movement, etc. by analyzing the image obtained from the camera module 110. For example, the baby crib 1 may determine the baby's facial expression by extracting the baby's face image from the acquired image image and comparing the extracted face image with a reference image stored in the memory.

Alternatively, the baby crib 1 may determine whether the baby is moving through a frame changed over time in the acquired image image.

If it is determined that the baby has not fallen asleep, the baby crib 1 turns off the camera module in step S4, and waits for a predetermined time in step S5.

The reason why the camera is turned off when the baby does not fall asleep is that while the baby is awake, he can move his head, arms, or legs. In other words, if your baby is moving, you can't accurately measure your baby's height or weight, so you're waiting for the baby to fall asleep.

After a certain period of time has elapsed, the baby crib 1 enters step S1 and turns on the camera module again, and then the sleeping state of the baby can be checked.

If it is determined that the baby has fallen asleep, the baby crib 1 turns on the weight detection sensor in step S6, and acquires body information of the baby in step S7.

When the baby falls asleep, the baby's movement disappears, so it is possible to accurately measure the baby's height and weight.

Specifically, the baby bed 1 measures the weight of the baby in the bed body 10 by driving the weight detection sensor 140. At this time, since the weight sensor 140 is installed on the mattress 111 on which the baby is lying, it is possible to accurately measure the weight of the baby.

In addition, the baby bed 1 drives the camera module 110 to measure the height of the baby in the bed body 10.

In this case, the camera module 110 may capture an image of a baby lying on the mattress 111 and recognize a distance from the baby's head to toes through the captured image.

For example, the camera module 110 may photograph a subject with a plurality of image sensors, analyze depth information from the captured image, and extract 3D information on the subject. Alternatively, the camera module 110 may include a Time-Of-Flight (ToF) sensor to determine a distance from a captured image to a scene from each pixel.

In addition, the camera module 110 may include a distance sensor for detecting a distance to an object. The distance sensor may include an ultrasonic sensor or an infrared sensor for measuring a distance between the camera module 110 and an object (baby).

In this way, the baby crib 1 may measure the height of the baby through the camera module 110 and measure the weight of the baby through the weight detection sensor 140.

Then, in step S8, the baby crib 1 transmits the acquired body information to an external device.

The baby crib 1 may store the acquired body information in a memory. In addition, the baby crib 1 may transmit the acquired body information to the user's terminal.

For example, as shown in FIG. 10, the baby crib 1 may transmit the acquired body information to the user's mobile terminal 50. In this case, a guide window 51 including body information may be displayed on the display of the mobile terminal 50.

The baby's height 51a and weight 51b may be displayed on the guide window 51. Accordingly, there is an effect that the user can easily check the body information of the baby measured through the baby crib 1.

In addition, the baby crib 1 may transmit the acquired body information to a server or a cloud. The server or cloud may include an application for providing information related to the growth or parenting of a baby. Accordingly, the server or the cloud may store and update the received body information, and store and manage changes according to the growth of the baby as data.

The server or cloud may transmit the updated data to the mobile terminal 50 through an application or the like.

For example, as shown in FIG. 11, the mobile terminal 50 may run an application to check growth data stored in the server or cloud.

When the application is executed through the mobile terminal 50, an analysis result screen related to the growth of the baby may be displayed. On the analysis result screen, information on the recently measured height 52 and weight 53 of the baby may be displayed.

In addition, the analysis result screen may show the current height and weight of the baby by comparing the average value of other babies. At this time, on the analysis result screen, if the current height and weight of the baby are less than the existing average value, child care tips 54 such as "Increase the amount of feeding" may be displayed.

In step S9, the baby crib 1 turns off the camera module and the weight detection sensor. That is, the baby crib 1 may turn off the camera module 110 and the weight detection sensor 140 when the measurement of the baby's body information is completed.

Meanwhile, when it is determined that the baby has fallen asleep in step S3, the baby crib 1 may further determine whether the current time is a set measurement time.

Here, the measurement time may be a preset time in order to measure the baby's body information. That is, the user may preset a reference time for measuring the height and weight of the baby. The measurement time may be, for example, 23 pm.

According to this configuration, since the baby's body information can be measured only at a predetermined time when the baby is sleeping, there is an effect of remarkably reducing measurement errors.

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

Referring to FIG. 12, in step S11, the 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 laptop computer, 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 baby 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 or not 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 the server or the cloud when the baby is behaving. Then, the server or the cloud may store the transmitted image and upload the stored image to the application. Therefore, the user can receive the baby's baby's beating image through a server or an application supported by the cloud using a mobile terminal.

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.
