Description

[0001] The present invention relates to a child care service system,

The present invention relates to a nursing home relief service system, and more particularly, to a technology for automatically capturing an image of a child by tracking a position of a child in real time and pressing the button of the terminal in an emergency.

In general, when an emergency switch is pressed in a parking lot of a public collective facility such as a day care center, an emergency notification method or a recognition technology for recognizing the emergency switch and for appropriately responding to the situation is well known .

However, when an emergency situation occurs in a collective facility, it is somewhat inadequate for the emergency service to recognize the emergency call and send it to the control center.

As a result of such a problem, a system for an emergency call in an emergency situation or an emergency situation has been proposed in a parking lot. For example, a system disclosed in Korean Patent Publication No. 10-0643564 (entitled " Parking Position Receiver with Emergency Call Function & A wireless recognition unit installed in the parking lot for recognizing and outputting the proximity of the ID card or the wireless remote control signal upon reception of the wireless remote control signal; An emergency bell installed in the vicinity of the wireless recognition unit and generating a signal for an emergency call; The identification code information obtained from the ID card and the position information related to the parking zone in the parking lot are output as the first output data so as to be used in the interlocking operation of the closed circuit vehicle or in the elevator call, And a control unit for outputting, as second output data, position information in which the emergency bell is installed when a call signal is generated from the emergency bell.

However, since the emergency bell for generating a signal for emergency call is installed in the parking lot, it takes a long time to locate the emergency bell when the emergency situation occurs.

[0004] The Korean Patent Registration No. 1300596 ("One-path emergency call system ") includes a terminal for transmitting / receiving a current location, an emergency switch for generating an emergency signal for emergency call in the event of an emergency, A plurality of receivers for receiving a current position signal of the terminal and the emergency switch, a repeater for communicating with the receiver and collecting a current position signal of the terminal and the emergency switch received by the receiver, A position recognition server which receives the current position signal of the terminal and the emergency switch received and calculates the current position information of the terminal and the emergency switch by using a position calculation algorithm; And a control center for monitoring the calculated current position information of the terminal and the emergency switch ; Corrects the position data by using a traverse technique improved location calculation algorithm of the location-aware server filters the area and calculates the average value and error rate, with the exclusion algorithm.

In the above-mentioned patent, the terminal includes a parking position confirmation button so that the current parking position of the user is recognized by the location recognition server and the emergency position button is provided so that the current position of the user can be transmitted to the location recognition server when an emergency occurs. The problem is that the user can only receive signals from the location recognition server by pressing the parking position confirmation button and the emergency button, respectively.

As a result, for example, it takes a long time to find a terminal held in an emergency and press the emergency button, so that the emergency situation may not be avoided.

Further, there is a problem that the user can not check the parking position because the user can not press the parking position confirmation button.

Meanwhile, in the above-mentioned patent, it is described that the position calculation algorithm of the position recognition server calculates the average value and the error rate by filtering the area, and corrects the position data by using the improved polygonal surveying technique through the exclusion algorithm. However, It is difficult to implement the above-mentioned patent in actuality even in the case of an ordinary technician.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a child care safe service system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a network diagram showing an example of a nursery relief service system of the present invention, and FIG. 2 shows an example of a configuration of a nursery relief service system of the present invention.

The terminals 10 and 12 are one-key terminals having first through third transmission / reception modules corresponding to three frequency bands.

The frequencies of use are 125 kHz, 13.56 MHz, and 2.4 GHz, and transmit / receive modules for transmitting and receiving at each used frequency are provided.

The first transmission / reception module uses a frequency of 125 kHz and can be used to control the opening / closing of a bar installed at a vehicle entrance gate.

The second transceiver module uses the frequency of 13.56 MHz and controls the opening and closing of the bar or the door of the public entrance door by approaching the terminals 10 and 12 to the reader installed at a specific position of the vehicle entrance gate or the common entrance.

In addition, the third transmission / reception module uses a frequency of 2.4 GHz and automatically transmits / receives data to / from the wireless sensor 20 so that the wireless sensor 20 tracks the position of the terminal 10 and 12 without any human operation.

The terminal includes a child terminal 10 and a vehicle terminal 12. In order to reduce the manufacturing cost of the terminal, all the transmission / reception modules are not provided. In case of the child terminal 10, the transmission / reception module related to the vehicle access gate is not provided . However, in the present invention, all transmission / reception modules are provided as examples.

In addition, the terminals 10 and 12 may or may not have a separate emergency button for notifying an emergency situation, and a switch may be installed to use one terminal 10 and 12 for both children's and guardian's vehicles .

The terminals 10 and 12 store class information and classification information as identification information. The class information includes, for example, a class name and a classroom. The classification information may include a car number or an identification number. For example, Identification number 1 means a vehicle, and number two or more can be predetermined to signify a guardian member.

Referring to FIG. 2, the wireless sensor 20 is installed along a column or a moving path of an underground parking lot to detect a frequency band of 2.4 GHz and wirelessly communicate with a third transmission / reception module of the terminals 10 and 12, It is about 50m.

The unique identifier of the wireless sensor 20 is added to the identification information received from the terminals 10 and 12 and added to the unique sensitivity of the terminals 10 and 12 to the control server 50 .

A photographing unit (30) is installed at a position adjacent to the wireless sensor (20) to normally photograph a predetermined area. The photographing unit 30 can be connected to the control server 50 via a separate relay 42, and the photographed image is transmitted to the control server 50 and stored.

When the control server 50 determines that the emergency situation is based on the information received from the terminals 10 and 12, the photographing unit 30 intensively photographs the area where the emergency situation has occurred under the control of the control server 50 .

The repeaters 40 and 42 receive the identification information and the image information from the respective receivers 20 or the photographing units 30 in a wired or wireless manner and transmit the identification information and the image information to the control server 50, To the receiver (20) or the photographing unit (30).

Here, although the repeaters 40 and 42 are connected to the wireless sensor 20 and the photographing unit 30, it is also possible to configure a repeater for connecting the vehicle access controller, the common front door controller and the voice emergency unit , And all of these repeaters can be connected to the main repeater.

The control server 50 judges the situation according to various information received from the repeaters 40 and 42, and transmits a control command corresponding thereto, and may include an analysis algorithm for this.

In addition, the control server 50 stores the reception sensitivity of each wireless sensor 20 in a database for a predetermined reference position in order to track the terminals 10 and 12. Assuming that the wireless sensor 20 is installed on each column 104 of the underground parking lot, as shown in FIG. 2, when it is assumed that the terminals 10 and 12 are located at the reference position along the travel path, each wireless sensor 20 Measures the reception sensitivity (dB) of the terminals 10 and 12 and converts them into a database.

At this time, since the communication distance of the terminals 10 and 12 is about 50 m, most of the wireless detectors 30 can detect the terminals 10 and 12 with different receiving sensitivities. Therefore, in order to minimize the complexity, Sensitivity can be stored in the reception sensitivity database 52 only for the sensitivity.

For example, for the reference position p1, the reception sensitivity in the column A1 is -10 dB, -15 dB in the column B1, -20 dB in the column C1, -20 dB in the column A2, -25 dB in the column B2, and -30 dB , It is possible to set the threshold reception sensitivity to -20 dB and exclude it when the reception sensitivity is less than -20 dB. Therefore, the reference position p1 is defined by the reception sensitivity pattern generated by the reception sensitivity received by the wireless sensor 20 located in the columns A1, A2, B1, B2, and C1, as will be described later.

On the other hand, the reception sensitivity database 52 also stores a reference reception sensitivity pattern for each parking zone 102. Since each parking zone 102 is constantly determined in contrast to the movement route, the reception sensitivity pattern can be accurately defined for each parking zone 102 in advance.

The home network server 60 is connected to the control server 50 and can receive information from the control server 50 from the terminals 10 and 12 and provides child care information and parking information to the caregivers terminal to provide.

Hereinafter, the nursery relief service system of the present invention will be described in detail with reference to Figs. 1 and 2. Fig.

For convenience of explanation, a protector vehicle having only one child enters the underground parking lot, parks in the parking area 102, and travels through the common entrance door 106 to the elevator 108 as an example .

Referring to Fig. 2, in the underground parking lot, pillars 104 are arranged in the order of A1 to C4, and a parking space 102 is defined between the pillars 104. [ A wireless sensor 20 is installed in each column 104, and a photographing unit 30 is installed in the vehicle travel path. Further, as described above, the position indicated by X represents the reference position for manufacturing the reception sensitivity database 52.

<Car parking>

2, when the protector vehicle enters the entrance gate, the child terminal 10 and the vehicle terminal 12 provided in the vehicle communicate with the vehicle entrance control unit 100 installed at the vehicle entrance gate at a frequency of 125 kHz. As described above, when the child terminal 10 does not use the frequency band used by the vehicle terminal 12, the child terminal 10 and the vehicle access control unit 100 may not communicate with each other.

The vehicle access control unit 100 receives the identification information from the vehicle terminal 12 and transmits the identification information to the control server 50 via the relay device 42. The control server 50 receives the identification information from the vehicle terminal 12 It is determined that the vehicle is a car and the bar is opened in the vehicle access control unit 100 through the relay device 42. [

At the same time, the control server 50 provides class information to the home network server 60 to inform the child and the vehicle that the vehicle has entered the home network server 60, and the home network server 60 transmits the information to the parent terminal.

When the vehicle passes through the entrance gate, the vehicle terminal 12 starts periodic communication with the wireless sensor 20, and as described above, the wireless sensor 20 transmits the class information of the measured vehicle terminal 12 and the distinction information , Transmits the unique identifier of the wireless sensor (20) and the measured reception sensitivity to the control server (50) through the relay (40).

The control server 50 generates a reception sensitivity pattern by combining the unique identifier of each wireless sensor 20 and the measured reception sensitivity by using a previously prepared reception sensitivity database 52, And determines the travel path of the vehicle in the underground parking lot by comparing with the reception sensitivity pattern.

The reception sensitivity database 52 has the structure as shown in Table 1. The reception sensitivity pattern for the reference position is prepared by providing the reference reception sensitivity corresponding to the wireless sensor sequence. In this example, the reception sensitivity for the reference positions p1 to p4 It shows the pattern.

Reference location Wireless sensor A1 Wireless Detector B1 Wireless Detector C1 Wireless Detector A2 Wireless Detector B2 p1 -10dB -15dB -20dB -20dB -20dB p2 -10dB -10dB -20dB -20dB -20dB p3 -10dB -10dB -15dB -20dB -15dB p4 -5dB -10dB -20dB -15dB -15dB

The reference reception sensitivity pattern varies depending on the order of the wireless sensor 20, which can be arbitrarily set. The received reception sensitivity with reference to the unique identifier of the wireless sensor 20 is arranged in the order of arrangement in the reception sensitivity database 52 Thereby generating a reception sensitivity pattern.

In addition, the number of the wireless detectors 20 to be applied is changed depending on how many dB of the critical receiving sensitivity is set. In this example, five wireless detectors 20 are applied by setting the inherent receiving sensitivity to -20 dB.

The control server 50 generates a reception sensitivity pattern by combining reception sensitivity and unique identifier transmitted from each wireless sensor 20 and compares the received reception sensitivity pattern with the reference reception sensitivity pattern of the reception sensitivity database 52, Determine the actual location.

For example, if the reception sensitivity pattern based on the reception sensitivity received from each wireless sensor 20 is -10 dB, -12 dB, -18 dB, -20 dB, and -22 dB corresponding to the reference reception sensitivity pattern of the reception sensitivity database 52, It can be roughly determined that the vehicle terminal 12 is at p2. Here, the reception sensitivity measured by each wireless sensor 20 does not exactly coincide with the reference reception sensitivity for each wireless sensor in the reception sensitivity database 52, and the reception sensitivity is the same even if it is within a certain deviation based on the reference reception sensitivity Can be set.

If the reception sensitivity pattern based on the reception sensitivity received from each wireless sensor 20 is -4 dB, -10 dB, -18 dB, -16 dB, and -18 dB corresponding to the reference reception sensitivity pattern of the reception sensitivity database 52, It can be roughly determined that the vehicle terminal 12 is at p4, and as a result, it is determined that the vehicle has made a left turn at the p2 position.

The control server 50 repeats this method to determine the travel path of the vehicle. When a similar reception sensitivity pattern is received from a certain point in time, it is determined that the vehicle is attempting to park.

When the parking is completed, since the reception sensitivity pattern generated by the reception sensitivity received from the wireless sensor 20 will be constant, the control server 50 transmits the reception sensitivity pattern constantly received to the reception sensitivity database 52 Compares the received sensitivity pattern with a reference reception sensitivity pattern of a certain parking zone, and then specifies and stores the parking zone 102a.

As described above, unlike the conventional case, the controller can automatically check and store the accurate parking zone even after the car parks the car and does not press the parking confirmation button in the parking zone, thereby increasing convenience.

On the other hand, the control server 50 can inform the guardian of the information about the parking zone through the speaker provided on the column A3 or A4 adjacent to the parking zone 102a where the vehicle is parked, among the speakers of the voice emergency unit provided for each column .

<Protection of children>

2, when the vehicle on which the child and the carer ride enters the entrance gate, the child terminal 10 communicates with the vehicle entrance control unit 100 installed on the vehicle entrance gate at a frequency of 125 kHz.

The vehicle access control unit 100 receives class information and classification information from the child terminal 10 as identification information and transmits the information to the control server 50 via the relay 42. The control server 50 transmits the class information and the classification information to the home network server 60 (The child having the identification number 1) to notify that the 'Hongdil-dong of the Azalea class' has entered, and the home network server 60 transmits the information to the guardian terminal.

When parking of the vehicle is completed and the child starts to move down from the vehicle toward the elevator 108, the movement of the child is tracked around the reference position in the same manner as described above.

Accordingly, the control server 50 can always track the position of the child in the parking lot, even if the child does not take any other action such as pressing a button of the terminal.

In the case where the reception sensitivity pattern transmitted from each wireless sensor 20 that senses the child terminal 10 is repeated during the predetermined period while the tracking process is being performed, the control server 50 notifies the child of an emergency .

In other words, when a child stays in the parking area 102 of the vehicle for a long time, the reception sensitivity pattern transmitted from each wireless sensor 20 that senses the child terminal 10 is naturally repeated in the same manner. The control server 50 determines whether the reception sensitivity pattern transmitted from each wireless sensor 20 that senses the child terminal 10 changes over time, It is judged that an emergency has occurred to the child.

Of course, although the child may be suspended for a long time as a personal problem rather than an emergency situation, the control server 50 may determine the emergency situation including the exceptional situation, Do not miss emergency situations.

If the control server 50 determines that the emergency situation is present, the control unit 50 controls the photographing unit 30 adjacent to the position determined as an emergency through the repeater 42 to photograph the location intensively and notify the worker at the control center.

Therefore, a worker at the control center can take appropriate measures according to the situation while watching the photographed image, and can notify the family that an emergency has occurred through, for example, calling an ambulance or through a guardian terminal.

According to such a structure, even if a child experiences a heart attack or is injured during the movement of the child to ride the elevator 108 and the child terminal 10 can not be used, the control server 50 automatically detects it It is advantageous.

On the other hand, in the process of tracking the movement of the child by the control server 50, the reception sensitivity pattern detected from the wireless sensor 20 installed adjacent to the common entrance door 106 corresponds to the reception sensitivity database 52 The control server 50 determines that the child is located at a position pT immediately before the common entrance door 106 and sends the common entrance door opening / To transmit the command.

Likewise, the elevator call location can be set at a distance of a certain distance from the common entrance door 106, and the control server 50 can set the elevator call position in the same manner as the common door 106 is opened And calls the elevator 108 when passing.

In this way, the child can conveniently use the moving access without having to open the common entrance door 106 directly or press the button of the elevator 108.

On the other hand, when the child gets out of the home to use the vehicle together with the carer and gets off the elevator 108 to get out of the underground sprung window, the child terminal 10 can detect the wireless sensor 20 adjacent to the common entrance door 106, Communication.

The control server 50 judges that the situation is a situation of leaving the common entrance door 106 to use the vehicle, refers to the class information transmitted from the wireless sensor 20, and transmits the stored parking information to the DID (Not shown), so that the child guardian can accurately recognize the parked parking zone 102a in which the vehicle is parked.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
