Description

Sleeping child check system and its operation method

The present invention relates to a sleeping child check system and an operating method thereof, and more particularly, to a sleeping child check system capable of confirming whether a child remains inside a vehicle.

In recent years, accidents in which children left unattended in school vehicles in the midst of heatwaves have lost their lives have occurred frequently. Accordingly, the government has enacted safety-related regulations that require the guide to check if there are any children left in the school vehicle, and it is applied to the field.

However, despite safety-related regulations, these regulations are not well observed in the field, and accidents in which children are still trapped in school vehicles continue to occur.

Accordingly, the government has made it mandatory to install a device that can check whether a vehicle has a sleeping child (that is, a sleeping child check device) in all school vehicles.

In this sleeping child check system, when a smartphone is tagged with a near field communication device (NFC) in the vehicle, the alarm sound is released, and the 'NFC method' and a beacon device that informs parents of this after entering the passenger's information is attached. The 'beacon method' that notifies parents when a child's bag approaches within 10m, the 'sensor method' that attaches a movement sensor and displays it on the driver's seat screen when motion is detected, and the inside and outside vehicle warning lights sound when the rearmost confirmation bell is pressed There is a 'bell method' that turns off.

However, in the case of the 'NFC method', card tagging may be difficult for children, and there is a high possibility that children lose the card. The 'beacon method' has a problem in that the child cannot be recognized properly if the child loses or returns the bag. The 'sensor method' had a problem with frequent sensor malfunctions and a larger error range compared to other methods.

The 'bell method' has a higher probability of preventing accidents than other methods because the driver directly presses the alarm bell to check it. However, since the 'bell method' does not allow parents to directly check whether the child has left the vehicle, parents may still have anxiety about the child's safety.

Also, in the 'bell method', if there is a child in the driver's blind spot, a safety accident may occur because the driver cannot find the child. In other words, there was a problem that the possibility of safety accidents still existed even with the 'bell method'. A bigger problem was that the driver of the vehicle turned off the power of the Sleeping Child system and drove it.

1 is a schematic diagram of a sleeping child check system in accordance with some embodiments of the present invention.

Referring to FIG. 1 , a sleeping child check system 100 according to some embodiments of the present invention includes a control box 110 , a bell terminal 120 , and a camera terminal 130 . In this case, each component of the sleeping child check system 100 may be installed inside or outside the vehicle.

The control box 110 may detect a driving state (or an operating state) of the vehicle, and control the operations of the bell terminal 120 and the camera terminal 130 based on the driving state.

Specifically, the control box 110 may detect the start and end of the driving based on the driving data for the on/off state of the vehicle. When the driving start of the vehicle is detected, the control box 110 may transmit a vehicle driving start notification to a pre-registered user. In addition, when the end of the vehicle operation is sensed, the control box 110 may transmit a vehicle operation end notification to a pre-registered user. Such notification can be performed in a push method.

Subsequently, when the ignition of the vehicle is turned OFF (that is, when the end of the vehicle operation is detected), the control box 110 sends an alarm operation command for activating the alarm of the bell terminal 120 to the bell terminal 120 . send to

Subsequently, the control box 110 may receive an alarm release signal indicating whether an alarm activated by an input button provided in the bell terminal 120 is released.

Subsequently, when receiving an alarm release signal from all the bell terminals 120 , the control box 110 transmits a disembarkation completion notification to a pre-registered user.

Also, when the vehicle is turned off, the control box 110 provides the captured image received from the camera terminal 130 to a pre-registered user. An image captured by the camera terminal 130 may be provided to the user for a predetermined time after the vehicle is turned off.

For example, after the vehicle is turned off, the camera terminal 130 may capture an image for about 10 minutes. The captured image is transmitted to the control box 110 . The control box 110 may upload the captured image to the integrated control server 300 so that a predetermined user can inquire the captured image.

Additionally, the control box 110 may determine whether a child exists in the vehicle by comparing the image previously captured by the camera terminal 130 with the image currently captured by the camera terminal 130 . If it is determined that there is a child inside the vehicle, the control box 110 may transmit a notification indicating an emergency situation to a pre-registered user and the integrated control server 300 . Comparing the image taken in advance with the image currently captured by the camera terminal 130 can be constructed through learning using artificial intelligence. It can recognize a child's face using artificial intelligence or attach a separate IR sensor and learn the image detected by the IR sensor to determine whether a person is left in the car.

The bell terminal 120 may generate an alarm in which a sound or light is generated, and has an input button capable of turning the alarm on/off. When the user presses the input button once, the alarm of the bell terminal 120 is activated (turned on), and when the user presses the input button once more, the alarm of the bell terminal 120 is deactivated (turned off). The bell terminal 120 may be controlled remotely. For example, when receiving an alarm operation command from the control box 110 , the bell terminal 120 may activate an alarm.

In addition, status information regarding the alarm activation of the bell terminal 120 may be transmitted to other devices. For example, when an activated alarm of the bell terminal 120 is released, the bell terminal 120 may generate an alarm release signal. The control box 110 may determine whether to release the alarm of the bell terminal 120 by receiving the alarm release signal.

Instead of the bell terminal 120, a fingerprint sensor may be installed on the boarding side of the vehicle. When children get on and off, the fingerprint sensor can be used to detect the fingerprint and identify the child. Of course, when boarding or disembarking using the identified child information, a notification can be sent to the registered terminal in a push manner. By checking these notifications, parents can know whether their children are in or out of the vehicle. In addition, when all the children who got on get off, it can be sent to the registered terminal in a push method that getting off is complete. Even though all children were notified from the vehicle, they were not informed of the child's getting off information, but the child may be left in the car.

A plurality of bell terminals 120 may be provided in the vehicle, and may communicate with one control box 110 wirelessly or by wire. In this case, each bell terminal 120 has a unique code, and the control box 110 can recognize only the alarm release signal of the bell terminal 120 including a pre-registered code.

When an alarm release signal is received from all the bell terminals 120 , the control box 110 may transmit a notification of disembarkation completion to a pre-registered user.

The camera terminal 130 may take an image and transmit the captured image to another device by wire or wirelessly. In addition, whether the camera terminal 130 is operated remotely by another device may be controlled.

For example, when receiving an image capturing command from the control box 110 , the camera terminal 130 may start capturing an image. An image captured by the camera terminal 130 may be transmitted to the control box 110 . The control box 110 transmits the captured image to the integrated control server 300 so that a pre-registered user can inquire the captured image at a desired time.

The camera terminal 130 may capture a still image or a moving image. In this case, the camera terminal 130 may capture an image using visible light, ultraviolet light, or infrared light. The captured image may be provided to a pre-registered user as described above, or may be used to determine whether there is a child in the vehicle.

The sleeping child check system 100 may further include a digital tacho graph (hereinafter, DTG) for a separate vehicle.

The driving recorder 140 is a device that records information about driving of a vehicle. The tachograph 140 may store information related to vehicle operation in real time, and may store driving data such as whether the vehicle is started, the location of the vehicle, whether the vehicle is speeding, rapid acceleration, and sudden braking as a database.

The driving data generated by the tachograph 140 may be transmitted to the control box 110 . The control box 110 may detect or determine whether the driving of the vehicle starts and ends based on the driving data received from the driving recorder 140 .

Additionally, the control box 110 may detect the driving state of the vehicle based on the received driving data. If the vehicle is driven in an abnormal pattern, the control box 110 may transmit a notification about this to a pre-registered user and the integrated control server 300 .

In the user terminal 200 , an application for receiving information from the sleeping child check system 100 may be installed.

The application installed in the user terminal 200 may provide a service start notification, a service end notification, a disembarkation completion notification, an emergency notification, etc. to the user in a pop-up form. However, the pop-up form is only one embodiment, and the method of displaying a notification may be variously modified and implemented.

In addition, although not shown in detail in the drawing, the application is a first interface screen on which vehicle location information, driving information, and getting off completion information are displayed, and image information captured through the camera terminal 130 installed in the vehicle can be inquired. It may include a second interface screen and a third interface screen for setting a specific time period for displaying a notification. However, these are only some embodiments, and the application may further include an interface screen that provides various information.

For example, the application provides services for 'secondary guardian registration', 'medication request creation', 'notification letter', 'attendance record check', 'confirmation of handover of children and women', 'schedule and notice', 'emergency contact network', etc. It can be provided to the user through the interface screen.

Here, the 'secondary guardian registration' is a service for registering a secondary guardian (eg, grandparent or aunt) to take care of a child on behalf of the primary guardian in case of emergency. 'Writing a medication request' is a service that can be inquired and executed at the facility if the child writes the contents to be administered while the child is in the facility. 'Notification Book' is a service that allows you to write or inquire about the contents of notifications for each child between the facility and the home. 'Check attendance record' is a service that allows you to check your child's attendance record by period. 'Confirmation of Handover of Children's School' is a service that allows you to automatically or manually check and record the handover of a child to a guardian at the time of the child's discharge. 'Schedule and Notice' is a service that allows you to inquire about event schedules and other notices hosted by the facility. The 'emergency contact network' is a service that allows you to inquire contact information so that you can contact the child's guardian immediately without checking a separate phone list. However, this is only an example of some services, and the present invention is not limited thereto.

A fingerprint sensor may be installed on the boarding side of the vehicle. When children get on and off, the fingerprint sensor can be used to detect the fingerprint and identify the child. Of course, when boarding or disembarking using the identified child information, a notification can be sent to the registered terminal in a push manner. By checking these notifications, parents can know whether their children are in or out of the vehicle.

The user terminal 100 may be a mobile communication device such as a mobile phone, or a laptop, personal computer (PC), personal digital assistant (PDA), handheld PC (HPC), webpad, tablet PC (Tablet PC), etc. may be various types of information terminals having communication ports. The user terminal 100 can access the Internet or a network using a communication port.

The integrated control server 300 may store and manage data received from the sleeping child check system 100 . In addition, the integrated control server 300 may remotely control the operation of the sleeping child check system 100 .

Specifically, the integrated control server 300 stores the driving information of the vehicle received from the sleeping child check system 100, the photographed image inside the vehicle, and predetermined user information, and stores the stored data in the user terminal 200. can be provided to

In this case, the driving information of the vehicle may include a current location of the vehicle, a driving start time, a driving end time, and the like. The captured image inside the vehicle may include a plurality of images captured by the plurality of camera terminals 130 . A predefined user may be added, changed, and deleted through the user terminal 200 .

The integrated control server 300 may determine whether the current state is an emergency by receiving a notification of whether an emergency is present from the sleeping child check system 100 or analyzing a captured image. When it is determined that it is an emergency, the integrated control server 300 may send an emergency notification to a pre-registered user, or deliver a notification to an employee so that a phone call is made to the pre-registered user.

The information communication network 500 may transmit data between a plurality of electronic devices using a preset communication protocol. The preset communication protocol may be any one of a TCP/IP protocol, a protocol conforming to IEEE 802.11, and a WAP protocol. However, the present invention is not limited thereto.

Hereinafter, each component included in the control box 110 of the sleeping child check system 100 according to an embodiment of the present invention will be described in detail.

2 is a block diagram of a control box of a sleeping child check system according to an embodiment of the present invention. Referring to FIG. 2 , the control box 110 includes a vehicle state detection unit 111 , an image storage unit 112 , an image comparison unit 113 , a user setting unit 114 , a control unit 115 , and a communication unit 116 . includes

The vehicle state detection unit 111 detects the driving state of the vehicle in which the sleeping child check system 100 is installed. The vehicle state detection unit 111 may receive the driving data from the above-described driving recorder 140 . Alternatively, the vehicle state detection unit 111 may receive data regarding the position and operation state of the vehicle from a separate sensor.

The vehicle state detection unit 111 may detect the start of the operation of the vehicle or the end of the operation based on the received data. For example, when the ignition of the vehicle is turned on and the location of the vehicle is changed, the vehicle state detection unit 111 may determine that the vehicle has started driving. Conversely, when the location of the vehicle is stopped and the vehicle's engine is turned off, the vehicle state detection unit 111 may determine that the operation of the vehicle has ended.

Additionally, in another embodiment of the present invention, the vehicle state detection unit 111 receives the tagging information from a separate tag terminal (150 in FIG. 5), and determines the start and end of the operation of the vehicle based on the received tagging information. can do. A detailed description thereof will be described with reference to FIG. 5 .

The image storage unit 112 stores an image previously photographed by the camera terminal 130 . Here, the pre-captured image refers to an image captured by the camera terminal 130 in a state where no one is in the vehicle. That is, the previously captured image may be used as a comparison control group for determining an emergency situation.

The image storage unit 112 may include a memory for storing data. The image storage unit 112 may store images according to respective positions and angles with respect to the camera terminal 130 . In this case, the image stored in the image storage unit 112 may be provided to the image comparison unit 113 and the control unit 115 .

The image comparison unit 113 compares the difference between the first image previously stored in the image storage unit 112 and the second image currently captured and received by the camera terminal 130 . Specifically, the image comparison unit 113 calculates the similarity between the first image and the second image. The calculated similarity is provided to the control unit 115 , and the control unit 115 may use the similarity level to determine whether there is an emergency.

In this case, the image used by the image comparison unit 113 may include a general screen photographed with visible light, and a hot screen photographed with infrared or ultraviolet light.

The user setting unit 114 stores a predetermined specific time zone and emergency contact information. In this case, the user setting unit 114 may store different information for each user account. A predetermined specific time zone and emergency contact information may be provided to the control unit 115 . For example, the specific time period may be set as a regular operating time of a school vehicle.

The control unit 115 determines the state of the vehicle, such as driving start, driving end, and disembarkation completion, based on the driving data received from the vehicle state detecting unit 111 .

Subsequently, the control unit 115 may transmit the operation start notification, the operation end notification, and the getting off completion notification to the user terminal 200 through the communication unit 116 .

In this case, the control unit 115 may transmit a notification to the pre-registered user terminal 200 only in a specific time period designated in advance for each user received from the user setting unit 114 . This is to minimize the user's interruption to work with unnecessarily many notifications. Through this, the user may receive the driving start notification, the driving end notification, and the getting off completion notification only during the regular operating hours of the school vehicle.

In addition, the control unit 115 transmits an alarm operation command to the plurality of bell terminals 120 provided in the vehicle to check the sleeping children inside the vehicle when the operation of the vehicle is finished.

Subsequently, the plurality of bell terminals 120 receiving the alarm operation command activate the alarm through light or sound. The driver releases the alarm by pressing an input button provided in each bell terminal 120 , and the alarm-cleared bell terminal 120 transmits an alarm release signal to the control unit 115 .

Subsequently, when receiving an alarm release signal from all the bell terminals 120 , the control unit 115 transmits a notice of getting off to a pre-registered user.

Additionally, the controller 115 transmits an image captured by the camera terminal 130 to the user terminal 200 of a pre-registered user when the operation of the vehicle is terminated. Also, the control unit 115 may upload an image captured for a predetermined time to the integrated control server 300 . The user terminal 200 may access the integrated control server 300 to view the uploaded image. Through this, the user can directly check whether the child remains in the vehicle, and the user's anxiety about the safety of the child can be reduced.

Additionally, the controller 115 may determine whether there is an emergency based on the similarity between the pre-stored first image received from the image comparison unit 113 and the second image received from the camera terminal 130 . For example, when the received similarity is smaller than the reference similarity, the controller 115 may determine that the current situation is an emergency situation.

The emergency determination operation of the controller 115 may be performed after the driver checks the inside of the vehicle. That is, after the disembarkation completion notification is transmitted to the pre-registered user, the controller 115 may determine that it is an emergency situation based on the similarity between the first image and the second image.

In this case, the control unit 115 may transmit a notification of an emergency situation to a user registered in advance in the emergency contact network regardless of a predetermined specific time period. In this case, the controller 115 may transmit an image currently captured by the camera terminal 130 to a pre-registered user along with a notification of an emergency situation.

In addition, the control unit 115 transmits a notification of an emergency situation to the integrated control server 300 and an image captured by the camera terminal 130 so that the staff of the integrated control server 300 can recognize that it is an emergency situation. can

Through this, the sleeping child check system 100 of the present invention can double check whether or not a child remains in the vehicle, thereby preventing a safety accident that may occur when the child is trapped in the vehicle.

Hereinafter, some embodiments of the sleeping child check system 100 installed in a vehicle will be described.

3 and 4 are diagrams for explaining a sleeping child check system installed in a vehicle according to an embodiment of the present invention.

3 and 4 , the sleeping child check system 100 according to an embodiment of the present invention may include a plurality of bell terminals 120 and a plurality of camera terminals 130 .

The plurality of bell terminals 120 may be disposed to be spaced apart from each other, and may be disposed adjacent to each of the plurality of camera terminals 130 . In this case, the number of the plurality of bell terminals 120 may be installed to be the same as the number of the plurality of camera terminals 130 .

The plurality of camera terminals 130 may be arranged to photograph different areas inside the vehicle. That is, the first photographing area R1 of the first camera terminal 131 , the second photographing area R2 of the second camera terminal 132 , the third photographing area R3 of the third camera terminal 133 , and the fourth photographing area R4 of the fourth camera terminal 134 may be set to not overlap each other or to overlap to a minimum.

The bell terminal 120 may be disposed adjacent to each camera terminal 130 . Through this, when walking around to cancel the alarm of the bell terminal 120 , a blind spot inside the vehicle that the driver must look at can be minimized. However, this is only an example, and the installation position of the bell terminal 120 may be variously modified and implemented.

3 and 4 , the number of the plurality of bell terminals 120 may be set differently from the number of camera terminals 130 . For example, the number of the plurality of bell terminals 120 may be greater or less than the number of camera terminals 130 .

Also, the bell terminal 120 may be disposed to be spaced apart from the camera terminal 130 . For example, the bell terminal 120 may be disposed in the blind spot of the camera terminal 130 so that the driver preferentially looks at the blind spot of the bell terminal 120 .

The control box 110 may be disposed inside a controller (not shown) of the vehicle, but this is only an example and may be installed in various locations of the vehicle. The control box 110 may be wirelessly connected to a plurality of bell terminals 120 and a plurality of camera terminals 130 . Through this, the sleeping child check system 100 may minimize the complexity of wiring installed in the vehicle.

5 is a view for explaining a sleeping child check system installed in a vehicle according to another embodiment of the present invention.

Referring to FIG. 5 , the sleeping child check system 100 according to another embodiment of the present invention may further include a tag terminal 150 .

The tag terminal 150 may detect tagging of the card held by the driver. In this case, the tag terminal 150 may operate in a short-range wireless communication (NFC) method, and may detect the tagging of the driver's card and transmit it to the control box 110 .

When the vehicle starts or ends, the driver may tag his/her card on the tag terminal 150 . This is to inform the user terminal 200 or the integrated control server 300 of the fact that the driver starts or ends the driving of the vehicle.

If the driver does not tag his/her card to the tag terminal 150 , the control box 110 may provide a notification to the user terminal 200 or the integrated control server 300 .

Through this, the sleeping child check system 100 can determine the exact timing for the start and end of the operation of the vehicle. When tagging for the end of the operation is detected, the control box 110 transmits an alarm operation command to the plurality of bell terminals 120 . The driver checks whether there is a child inside the vehicle in the process of canceling the alarms of the plurality of bell terminals 120 .

Subsequently, when the control box 110 receives the alarm release signal from all the bell terminals 120 , the control box 110 transmits a notification of getting off to a pre-registered user.

In addition, when tagging for the end of the operation is detected, the control box 110 uploads the captured images received from the plurality of camera terminals 130 to the integrated control server 300 , and the user terminal 200 is photographed. Makes the video viewable.

Through this, the user can directly check whether or not the child remains in the vehicle through the image. Accordingly, the user's anxiety about the safety of the child can be reduced.

Then, after the disembarkation completion notification is transmitted to the pre-registered user, the control box 110 calculates a similarity between the image captured by the camera terminal 130 and the pre-stored image.

Then, when the calculated similarity is smaller than the predetermined reference similarity, the control box 110 determines that the current child is in an emergency situation in the vehicle.

Subsequently, the control box 110 transmits a notification of an emergency situation and a captured image to the user terminal 200 of a pre-registered user.

Through this, the sleeping child check system 100 of the present invention can double check whether or not a child remains in the vehicle, thereby preventing a safety accident that may occur when the child is trapped in the vehicle.

6 is a flowchart illustrating a method of operating a sleeping child check system according to an embodiment of the present invention. Referring to FIG. 6 , in the operating method of the sleeping child check system according to an embodiment of the present invention, first, the control box 110 detects the start of driving based on the driving data of the vehicle ( S110 ). When the ignition of the vehicle is turned on and moved, the control box 110 may detect that the vehicle starts driving. The control box 110 may determine whether to start driving based on the driving data received from the above-described driving recorder 140 .

Additionally, the control box 110 may detect whether the operation starts or not through the tagging of the tag terminal 150 shown in FIG. 5 .

Subsequently, when the driving start of the vehicle is detected, the control box 110 transmits a driving start notification indicating the start of driving of the vehicle to the user terminal 200 and the integrated control server 300 of the pre-registered user (S120) .

Then, the control box 110 detects the end of the operation based on the driving data of the vehicle (S130). When the ignition of the vehicle is turned off, the control box 110 may detect that the vehicle stops running. The control box 110 may determine whether to terminate the operation based on the operation data received from the above-described operation recorder 140 . In addition, the control box 110 may detect whether the operation is terminated through the tagging of the tag terminal 150 shown in FIG. 5 .

Then, when the end of driving of the vehicle is sensed, the control box 110 transmits a service end notification indicating the end of the vehicle to the user terminal 200 and the integrated control server 300 of the pre-registered user (S140).

Then, the control box 110 transmits an alarm operation command to all the bell terminals 120 installed in the vehicle (S150). Through this, notifications of all the bell terminals 120 installed in the vehicle are activated. The alarm-activated bell terminal 120 generates light or sound.

Then, the driver presses the input button provided in the bell terminal 120 to cancel the activated alarm. When the input button is pressed, the alarm of the bell terminal 120 is released, and the bell terminal 120 transmits an alarm release signal to the control box 110 .

The plurality of bell terminals 120 are installed in different positions of the vehicle, and the driver can check whether the child remains in the vehicle while walking around to release each bell terminal 120 .

Subsequently, when an alarm release signal is received from all the bell terminals 120 , the control box 110 transmits a notice of getting off completion to the user terminal 200 and the integrated control server 300 of the pre-registered user ( S160 ) . Through this, the user may recognize through a notification that the check on whether the child remains in the vehicle is completed.

7 is a flowchart illustrating a method of operating a sleeping child check system according to another embodiment of the present invention. Referring to FIG. 7 , following the aforementioned step S140 , when the end of the vehicle operation is detected, the control box 110 transmits an operation command to capture an image to the camera terminal 130 for a predetermined time ( S210 ). For example, after the vehicle is turned off, the camera terminal 130 may capture an image for about 10 minutes.

Then, the control box 110 receives the image captured by the camera terminal 130, and uploads the received image to the integrated control server 300 (S220). A pre-registered user may inquire an image uploaded to the integrated control server 300 through an application installed in the user terminal 200 .

Through this, the user can directly check whether the child remains in the vehicle, and thus the user's anxiety about the safety of the child can be reduced.

Next, the control box 110 analyzes the captured image data to determine whether the child remains in the vehicle (S230).

Specifically, the control box 110 calculates a similarity between the first image pre-stored in the image storage unit 120 and the second image currently received from the camera terminal 130 . Subsequently, when the similarity between the first image and the second image is smaller than the reference similarity, the control box 110 may determine that the child remains in the vehicle.

Next, when a child is detected through image analysis, the control box 110 transmits an emergency notification and a currently captured image to the user terminal 200 and the integrated control server 300 of the pre-registered user (S250). .

Through this, the sleeping child check system 100 of the present invention can double check whether or not a child remains in the vehicle, thereby preventing a safety accident that may occur when the child is trapped in the vehicle.
