Description

System for searching the lost children or man}

The present invention relates to a location tracking system of a wearer that tracks the location of a child, a mental patient, a dementia patient, and the like, and more specifically, a specific information of the wearer, such as a bracelet, a necklace, or a child prevention card containing a name and address. The present invention relates to a wearer's location tracking system that includes a stored wireless ID tag and detects a wearer's current location in real time using a tracking detector installed in a specific region or throughout the country.

Thousands of lost children occur in Korea alone during the year. Some of them return to their homes after they have been confirmed by their parents, but most of the lost children are sent to orphanages without finding their parents and are growing up as orphans. Mia occurs mainly in congested spaces such as markets, amusement parks, amusement parks, playgrounds, etc., near homes or with parents.

When a child is lost in such a place, the place where the information broadcast device is equipped with a guide broadcast is searched for the name and address of the child, but the child cannot be found quickly, and the parents' hearts continue until they find the child in anxiety and anxiety. It can also be a lifelong burden for parents if they don't find a lost child.

Conventionally, the means used to prevent the loss of children mainly use ribbons or bands worn on the wrist with a small number of children's names, addresses, and contacts, but they are not likely to be lost. This is brought about. In particular, if you lose the means to prevent the loss of children who do not know their address or contact information, and the likelihood of finding a parent is less likely to eventually be sent to an orphanage to grow orphans.

What is important in the process of developing the missing child is that if the missing child is reported and tracked at the time of the missing child, the probability of finding the missing child is increased because the moving radius of the missing child is relatively small. However, in reality, there is a difficult problem due to lack of miraculous power, indifference, or lack of police power to find a lost child.

In other words, when a child is lost, the parent begins to search around the place where the child is lost. However, people's indifference to the fact that Mia is not her child and lack of time due to her living prevents her from investing enough manpower and time to search Mia. Moreover, after the initial failure of the MIA search, the MIA is reported to the police station. However, since the police force invests a lot of manpower and time in security and traffic problems, it is impossible to invest enough manpower and time in MIA search. Therefore, the more time passes, the more difficult it is to search for lost children. If you're lucky, parents can visit a police station where Mia is protected, but this is rare. However, it is difficult to find Mia because most of Mia has no idea of a place and moves to the wrong place at all.

In addition to the above-mentioned infants, adult mental disorders or dementia patients are also frequently missed in the absence of protection of their families. Unlike Mia, these mentally ill or dementia patients are perceived as adults, so they don't pay much attention and fall far below the probability of finding Mia.

The present invention is to solve the above problems, an object of the present invention is to embed a wireless ID tag that stores the specific information of the wearer, such as bracelets, necklaces, or a child identification card containing the name and address, within a specific area Another aspect of the present invention is to provide a wearer's location tracking system that can track a location by detecting a wearer's current location in real time using a tracking detector distributed throughout the country.

As shown, the wireless ID tag 10 stores the identification information of the wearable child (mummy) to be readable wirelessly from the outside, and the wireless ID including the personal information through data transmission and reception with the wireless ID tag 10. In order to determine the location of the tag 10 in real time, a plurality of tracking detectors 20 and a plurality of tracking detectors distributed in a specific region or throughout the country, and missing tracking information including the missing child information are input. And a host computer 40 for transmitting the Mia tracking command and analyzing the detection signal input from the tracking detector 20 to notify the location of the Mia. Particularly, the host computer 40 is connected to the personal computer 30 through the Internet. It is connected to a mobile phone 60 or a general landline phone 70 through a telephone station.

The wireless ID tag 10 is worn by a child, and as shown in FIG. 2, includes an antenna 101, a rectifying and demodulating unit 102, a control unit 103, and a memory 104. Doing. The antenna 101 receives a radio frequency signal and also transmits personal information of a child embedded in the radio ID tag 10 as a radio signal. The antenna 101 may be generally thin in shape using a stripline antenna or using an antenna in the form of a coil.

In addition, the rectification and demodulation unit 102 supplies power for operation by using a high frequency signal among the radio frequency signals input through the antenna 101, and demodulates and outputs a control command input in a pulse form. The radio frequency signal input to the radio ID tag 10 preferably uses a high frequency to obtain a power source, for example, uses a radio frequency of 2.4 GHz. In comparison, the input radio frequency signal, that is, the signal output from the radio ID tag 10 transmits the signal to the tracking detector 20 using 13.56 MHz.

In addition, the control unit 103 receives a pulse signal output from the rectification and demodulation unit 102 and performs a corresponding operation. For example, when a command to transmit the information stored in the current wireless ID tag 10 is input, the controller 103 reads the data stored in the memory 104 and modulates the rectification and demodulation unit 102. Wireless transmission through the antenna 101.

The memory 104 stores the unique information of the wireless ID tag 10 and is read by the controller 103. The memory 104 uses a nonvolatile memory device that can be written many times. The data writing to the memory 104 is performed by the control unit 103 having recording means or by a separate memory recording means.

The wireless ID tag 10 having the above configuration is manufactured in the form of a card and worn on children, or attached to ornaments that can be worn for a long time such as necklaces or bracelets. Of course, it is also possible to attach it to other jewelry. The personal information stored in the wireless ID tag 10 becomes unique information for each child.

The tracking detector 20 is distributed in a specific place or throughout the country, generates and radiates a radio frequency signal, and receives a radio frequency signal radiated therefrom if the radio ID tag 10 exists in an adjacent position. Since the unique personal information stored in the responding radio ID tag 10 is transmitted to the received radio frequency signal, the tracking detector 20 detects this information and transmits it to the host computer 40 through the Internet or a dedicated line.

Referring back to FIG. 1, the tracking detector 20 is connected to the host computer 40 through the Internet, and can be constructed using a dedicated line as well as the Internet. Also, the tracking detector 20 may be a place where a child may be lost, for example, a school, a preschool, a kindergarten, a small supermarket, a stationery, a children's park, a game room, a moving vehicle, a port, an airport, a highway gate, a bank, a public place, a temple, It can be installed in various places such as churches, mia shelter, terminals, etc.

The host computer 40 simultaneously controls all the tracking detectors 20, 21, ..., n installed in the above places. For convenience of explanation, one tracking detector 20 will be described as an example, but the operations of the remaining tracking detectors 21, 22,.

3 is a block circuit diagram of the tracking detector 20, which includes an antenna 201, a modulator 202, a control unit 203, a memory 204, a communication interface 205, and a power supply unit. (206).

The antenna 201 transmits a radio frequency signal and also receives a radio frequency signal input from the radio ID tag 10. The radio frequency signal transmitted through the antenna 201 is about 2.4 GHz, and the radio frequency signal received by the antenna 201 is about 13.56 MHz. Of course, these frequencies can be changed.

Also, the demodulator 202 modulates a radio frequency signal transmitted through the antenna 201 and demodulates an input radio frequency signal. The demodulator 202 may be configured using circuits that are commonly used.

In addition, the controller 203 controls the tracking detector 20 by using the program and operation data stored in the memory 204. In addition, the communication interface 205 is for data communication through the Internet or a dedicated line and performs data communication with the host computer 40 located at a remote location. Reference numeral 206 denotes a power supply unit for supplying power to the tracking detector 20.

The tracking detector 20 generates and radiates a predetermined frequency signal in accordance with an infant (or wearer) tracking command from the host computer 40, and reads personal information of a specific wireless ID tag 10 that responds to the radiation. Reading of personal information in the tracking detector 20 can be performed in two ways. First, when the personal information is stored in the tracking detector 20 and compared with the personal information stored in the wireless ID tag 10 which is reacted, and the two personal information are the same, the result is transmitted to the host computer 40. It is. Second, all the personal information in response to the radiation of the radio frequency signal is transmitted to the host computer 40 together with the identification information of the corresponding trace detector 20, and the host computer 40 analyzes and judges the information to determine the location of the lost child. To identify. In the description of the present invention, the latter will be described by way of example.

In addition, the host computer 40 transmits a tracking command to each of the tracking detectors 20, 21, .., n when a command for requesting tracking of the missing child is input and displays the location of the missing child. . 4 is a block circuit diagram of the host computer 40 as described above.

As shown, the communication interface includes a communication interface 401, a control unit 402, a search unit 403, a MIA database 404, an ARS response unit 405, and an ARS call unit 406. .

The communication interface 401 is for data communication with each tracking detector 20 through the Internet or a dedicated line.

In addition, the controller 402 operates the host computer 40 using a program and control data necessary for the operation of the host computer 40, and includes a built-in memory in which the program and the operation data are stored.

In addition, the search unit 403 retrieves the data input from each tracking detector 20 through the communication interface 401, reads the location of the lost child and transmits it to the control unit 402.

In addition, the lost (wearer) database 404 stores the personal information input by the user when the lost occurs. The stored image information is read by the control unit 402 and then transmitted to the respective tracking detectors 20, 21, ..., n together with the tracking command.

In addition, the ARS answering machine 405 and the ARS call unit 406 are used to respond to a case of a lost signal via the telephone station 50 using the mobile phone 60 or the wired telephone 70. The wearer's location tracking system according to the present invention can be performed using the personal computer 30 as well as the mobile phone 60 or the phone 70.

Referring to the flowchart of Figure 5 the operating state of the position tracking system of the wearer of the present invention having the configuration as described above are as follows.

First, it is assumed that a child wears a wireless ID tag 10 in which personal information is stored. The wireless ID tag 10 is provided for a fee or free to members who wish to use the system of the present invention for the tracking of missing children.

If a child is lost while wearing the wireless ID tag 10 as described above, the mobile phone 60 or the phone 70 or the personal computer 30 connected to the Internet to report the occurrence of missing and tracking. Figure 6 shows an example of a screen for "report missing and trace request". This screen uses a personal computer 30, and in the case of using the mobile phone 60 or the phone 70, calls directly with a counselor or applies using the ARS responder 405.

The data necessary for reporting and tracking the loss of infants is the child's unique personal information such as identification code, social security number, and gender. Of course, it is obvious that it is also possible to assign other unique identifiers to identify the missing child. In the case of a member, a database of member children exists in advance, so the host computer can be configured to automatically process only the name and social security number.

As described above, when the MIA report and the tracking request are received through the personal computer 30, the mobile phone 60, and the phone 70, the host computer 40 immediately transmits the missing tracking command to all the tracking detectors. When the lost tracking signal is transmitted, each tracking detector immediately transmits a radio frequency signal.

When the radio frequency signal is transmitted, all radio ID tags 10 in the transmission range of the radio frequency signal react. When the personal information stored in the corresponding wireless ID tag 10 is input from the reacted wireless ID tag 10, the tracking detector transmits the input personal information to the host computer 40.

The host computer 40 searches for the presence of the same personal information as the personal information input by the MIA notice using the entered personal information. As a result of the search, if there is the same personal information, the tracking detector which transmitted the information is searched and the information is read in the place where it is located.

Once the location has been confirmed by the reading, the police station or the petitioner for tracking the child's outbreak will be notified of the location via the hotline. If the applicant wants to be notified using the telephone (cell phone or telephone) at the time of location notification, the location of the lost child is notified through the ARS call unit 406 of the host computer 40. At this time, since the tracking position changes as the lost child moves, the moving position of the lost child is continuously tracked until a request is found to stop the tracking. As a result of the tracking, if the user leaves the area of the tracking detector in charge of a specific place, the applicant is immediately notified by telephone of the change of location.

In the above description, the example of Mia is explained, but it is obvious that the same applies to the elderly, the mentally ill, and the demented. For example, a dementia patient may also be protected by wearing a wireless ID tag in which guardians input personal information of a dementia patient in advance and requesting location tracking when the dementia patient is missing. Soldiers on duty also have the advantage that the superior can check the working status by wearing a wireless ID tag that records their unique personal information on the dog tag.

According to the present invention, such as a bracelet, a necklace, or a child ID card containing a name and address, or a wireless ID tag that stores the specific information of the wearer, such as a dog line, and installed in a specific area or distributed throughout the country By using a detector, the location of a lost child, an elderly person, a mental patient, a dementia patient, and a soldier may be detected in real time.
