It will be apparent to those skilled in the art.

1 is a diagram showing the configuration of a device for preventing the loss according to an embodiment of the present invention.

Referring to FIG. 1, the apparatus for preventing the loss 100 includes a user interface unit 110, a living zone setting unit 120, a GPS information receiving unit 130, a lost road prediction unit 140, a living zone re-entry induction unit 150, The living zone information storage unit 160 and the display unit 170 are provided.

Preferably, the anti-lost device 100 of FIG. 1 is always carried by an elderly person to be protected (hereinafter, referred to as a protected person for convenience of explanation).

Hereinafter, the function of each component will be described.

The user interface 110 includes a keypad or a touch pad for searching and inputting various types of information or commands, so that a guardian (in some cases, a person to be protected) can set a right to be protected.

If the life zone setting operation is requested, the life zone setting unit 120 provides a life zone setting window requesting the life zone setting and sets the life zone of the person to be protected based on the information input through the life zone setting window.

The GPS information receiver 130 receives and analyzes GPS information provided from the satellite 400 for GPS service to determine the location and time of the anti-lost device 100. That is, the position and time of the person to be protected carrying the loss prevention device 100 are grasped.

The loss prediction unit 140 checks whether the location of the person to be protected is located in the living area and detects whether the person to be protected is leaving the living area. As a result of the detection, if the guardian has left the right of life, the cognitive ability of the protected person is tested, and if it is confirmed that there is no cognitive ability, the subject is determined to be no longer able to reenter the life zone by his own power, and then the reentry guidance unit 150 for the right of life is entered. Notify the protected person that they have been lost.

In addition, the position and time information of the person to be protected obtained through the GPS information receiver 130 is sequentially stored in the life zone information storage unit 160, and later, the user may reset the right to live or the guardian grasps the track of the person to be protected. Allows you to perform additional tasks such as

The living area re-entry induction unit 150 includes a guidance information providing unit 151 connected to the monitor and the speakers 171 and 172, and a guardian call unit 152 connected to the telephone network or the internet network 200. Accordingly, when the living area re-entry induction unit 150 is informed that the person to be protected is lost from the loss prediction unit 140, an image for prompting the person to be re-entered into the life area through the induction information providing unit 151 and Play the voice. Nevertheless, if the guardian does not re-enter the living zone within the set time, the guardian call unit 152 requests the guardian to set a phone connection to the guardian terminal previously set so that the guardian and the guardian can make a phone call. .

Preferably, the guided image provided by the guided information provider 151 is implemented to be as simple as possible to be easily recognized by the person to be protected. For example, as shown in FIG. 2, only an arrow indicating a moving direction of the current protected subject is displayed so that the protected subject can recognize the moving direction more easily and accurately.

If the telephone connection to the guardian terminal fails, the guardian terminal periodically sends the guardian's location and time information until the telephone connection is successful, so that the guardian can easily find the guardian through the received information. .

The life zone information storage unit 160 stores the location information of the life zone set through the life zone setting unit 120 and simultaneously stores the position of the person to be protected obtained through the loss prediction unit 140 in chronological order.

The display unit 170 includes a monitor 171 and a speaker 172, displays various images through the monitor 171, and reproduces audio through the speaker 172. Accordingly, the display unit 170 may provide a moving path for reentry into the living zone to the protected person who is going to reenter the living zone, or may accurately display the living zone to be selected by the photo to the guardian who wants to set the living zone. .

3 is an operation flowchart schematically illustrating a method for preventing the loss according to an embodiment of the present invention.

First, the living rights of the person to be protected are set through the initialization process (S1).

After the lifespan of the person to be protected is established through step S1, if the loss prevention operation is started in earnest, the loss prevention apparatus receives the GPS information provided by the satellite for the GPS service. The received GPS information is analyzed to obtain the current location and time of the person to be protected who carries the loss prevention device, and it is detected whether the person to leave the living area is referenced with reference to this (S2).

As a result of the detection of step S2, if the person to be protected has left the living area set through step S1, the loss prevention apparatus repeatedly provides an image and an audio for inducing the person to be re-entered into the life area (S3).

In spite of the operation of step S3, if the guardian fails to re-enter the living zone, the telephone connection with the guardian is proceeded (S4), so that the guardian can directly re-enter the guardian into the living zone.

4 is a flowchart illustrating an operation of setting a living zone according to an embodiment of the present invention (S1) in more detail. This is performed by the guardian requesting a life setting operation through the user interface 110.

First, when a life zone setting operation is requested, a life zone setting window having a GUI (Graphic User Interface) for allowing a guardian to manually set a life zone of a person to be protected is displayed on the monitor 171 (S11).

Accordingly, the guardian selects and sets a living zone including places where the subject of the protection mainly resides (for example, a house, a senior citizen's boat, a park, and a bus stop) through the living zone setting window (S12).

In step S12, a method of selecting and setting a living zone through the living zone setting window may be implemented in various forms. For example, as shown in FIG. 5, a method of directly searching and selecting a large number of places where a subject of protection mainly resides and visits, and sets a living space to include these places, or only one place as shown in FIG. When selected, there may be a method of setting a living zone in all of the predetermined areas including the same.

When the living zone is completed through step S12, the location information thereof is obtained and stored in the living zone information storage unit 160 (S13).

7 is an operation flowchart for explaining in more detail the loss prediction step (S2) according to an embodiment of the present invention.

First, GPS information provided from the satellite for GPS service 400 is received and analyzed (S21) to obtain location and time information of a person to be protected (S22).

Then, by analyzing the acquired position information of the person to be protected based on the life zone set by the guardian, it is checked whether the person to be protected has left the right to life (S23).

When the result of the check in step S23 indicates that the person to be protected has left the living area, a few simple questions are used to check whether the person to be protected can go to a desired destination or a specific place by itself, that is, to check whether the cognitive ability is normal. (S24).

The questions used in step S24 only need to confirm whether the cognitive ability is normal, so that it is very simple and easy, such as the name, age, social security number, or addition and subtraction problems of the person being protected.

If the correct answer rate for the answer input to the question of step S24 is calculated, and the calculated correct answer rate is higher than a preset value, it is determined that the cognitive ability of the person to be protected is normal (S25).

As a result of the determination in step S25, if the cognitive ability of the person to be protected is normal, after requesting input of the destination to be protected currently (S26), it is detected whether the person to be protected enters the destination (S27).

If the guardian inputs a destination, it is further checked whether the input destination is located in a movable area. In other words, it checks whether the place is adjacent to the living area or visited before (S28).

As a result of checking in step S28, if the input destination is a movable place, the living zone is corrected so that the newly entered destination is included in the living zone (S26).

On the other hand, when the determination result of step S25 is that the cognitive ability of the person to be protected is abnormal, the destination cannot be input in step S27, or the destination input through step S28 is an unmovable area, the person to be protected no longer finds the desired destination by self. Check that it is a difficult state to go and get lost (S27).

8 is an operation flowchart for explaining in more detail the lifestyle entry guide step (S3) and the guardian notification step (S4) according to an embodiment of the present invention.

When it is confirmed that the person to be protected is lost through the lost prediction step (S2), the loss prevention apparatus repeatedly reproduces the video and audio for inducing the reentry of the living area (S31).

In order to provide an image and audio for inducing the re-entry of the living zone in step S31, the loss prevention apparatus searches the living zone information storage unit 160 to select the most frequently visited places, and then selects the selected place and the location of the protection target. Based on this, the movement path of the protected person is secured. In addition, by supporting video and audio corresponding to the movement route, the person to be protected can reenter the living area.

In spite of the operation of step S31, if the person to be protected does not reenter the living zone within the set time (S32, S33), the person to be protected is not only lost, but the cognitive ability is markedly dropped and no longer able to reenter the living zone by self. Then, by requesting a telephone connection to the guardian terminal so that the subject and the guardian can make a phone call (S34).

If the telephone connection with the guardian terminal fails (S35), a message including the current location and time information of the person to be protected is generated until the telephone connection with the guardian terminal is successful (S36). .

In this way, the loss prevention device and method of the present invention allows the elderly to move freely within their own living area, but if the elderly are lost and leave the living area, the guardian can directly prevent the elderly from getting lost. Make sure

In the above description, for convenience of explanation, the protection subject is limited to the elderly. However, not only the elderly but also all persons who are likely to be lost due to their cognitive abilities are remarkably low, of course.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common in the art that various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those skilled in the art.
