Description

  The present invention relates to a lost child prevention system using a wireless tag in facilities such as a shopping center, a supermarket, an amusement park, and a theme park.

  Conventionally, a system using a wireless tag has been proposed in order to prevent a lost child that may occur in a facility such as a shopping center or an amusement park. For example, a wireless tag (IC tag) is attached to a person to be protected, and a portable interrogator that transmits an interrogation signal to the radio tag and receives a response signal from the radio tag is provided. When the interrogator continues to transmit the interrogation signal and the response signal from the radio tag cannot be received, the interrogator determines that the interval between the interrogator and the radio tag has spread beyond a certain distance, and issues an alarm from the interrogator. There is something like that (see, for example, Patent Document 1).

In addition, the telephone number of the mobile phone owned by the guardian is stored in a lost tag with a built-in wireless tag (RFID), and the lost tag is attached to the person to be protected. If the protected person who lost the child possesses the lost child tag, the tag reader reads out the stored interrogation signal to the lost child tag to read the stored telephone number, and calls the telephone number. In some cases, the guardian is informed that the person to be protected is lost (see, for example, Patent Document 2).

  However, the conventional lost child prevention system as described above has a problem that must be solved in the following points. In other words, in the system using the former portable interrogator, if the strength of the question signal transmitted from the interrogator is weakened, even if it is difficult for the person to be protected to get lost, it is protected from the guardian. There is a concern that the question signal may not reach the wireless tag because there is a shield between the target person and a warning may be issued. Conversely, when the strength of the question signal is increased, for example, a hierarchical structure Even in situations where the guardian goes up or down the stairs without permission from the guardian in the building of the building, that is, the situation where it is easy to get lost, the question signal from the interrogator reaches the wireless tag. There was a concern that no warning would be given while he was.

  Furthermore, in the latter lost child prevention system using a lost child tag, the phone number of the guardian is stored in the lost child tag, so that the person who took the lost child reads the phone number from the lost child tag in good faith and contacts the guardian. There is no problem if it is done, but it may be possible to read the phone number maliciously and request a ransom from the guardian, for example, which is a problem from the viewpoint of protecting personal information.

  The present invention has been made based on such circumstances, and the purpose of the present invention is to protect the personal information of the guardian or the person to be protected while ensuring that the person to be protected is likely to get lost. It is intended to provide a practically useful lost child prevention system.

  The lost child prevention system according to the present invention allows a guardian and a person to be protected to wear a wireless tag including a storage unit for individual identification information and a transmission unit for individual identification information stored in the storage unit. In addition, a plurality of tag readers that receive individual identification information transmitted from wireless tags respectively attached to a guardian and a person to be protected are provided at various locations in the facility. And the individual identification information memorize | stored in the memory | storage part of the radio | wireless tag with which the guardian was mounted | worn is registered as guardian identification information, and it memorize | stores in the memory | storage part of the radio | wireless tag with which the protection subject protected by the said guardian is mounted | worn The individual identification information thus registered is registered as subject identification information. Thus, based on the individual identification information received by the tag reader and the guardian identification information and the target person identification information registered by the identification information registration means, the location of the guardian and the protection target person in the facility is recognized. If it is determined whether or not to issue a lost child warning depending on the location of the guardian and the person to be protected, and if it is determined to issue the lost child warning, for example, the lost child warning is given to the portable terminal carried by the guardian It is a thing.

  According to the present invention in which such measures are taken, while protecting the personal information of a guardian or a person to be protected, a warning can be reliably issued when the person to be protected is likely to get lost, which is highly practical. Can provide a lost child prevention system.

The best mode for carrying out the present invention will be described below with reference to the drawings.
In this embodiment, a large supermarket having a hierarchical structure is illustrated as an example of a facility where the lost child prevention system of the present invention is introduced.

  FIG. 1 is a block diagram showing the system configuration of the present embodiment. The lost child prevention system according to the present embodiment includes a plurality of wireless tags 1 respectively attached to a guardian (parent) and a protection target person (child) who enter the facility, and data stored and held in the wireless tag 1 is not stored. A plurality of access points 4 capable of wireless communication between an information terminal 2 having a tag reader that can be read by contact communication and a portable terminal 3 carried by a guardian, and portable wireless control for controlling the operation of each access point 4 Unit 5, a plurality of floor-embedded tag readers 6 embedded in the floors of various places in the facility, a reader control unit 7 for controlling the operation of each tag reader 6, a tag return box 8 with a tag reader, and this return box 8 includes a reader control unit 9 that controls the tag reader attached to 8 and a management server 10 that plays a central role in the system. The management server 10, the information terminal 2, the portable wireless control unit 5, and the reader control units 7 and 9 are connected by a communication line such as a LAN (Local Area Network).

  The wireless tag 1 is a small and lightweight tag in which an IC chip and an antenna are provided on a tag-like substrate. The IC chip includes a non-volatile storage unit, a reception unit that demodulates radio waves received by the antenna and writes the data to the storage unit, and a transmission unit that modulates data read from the storage unit and transmits the data from the antenna. Has been. In the storage unit, ID information as individual identification information is fixedly set in advance at the manufacturing stage. When a predetermined inquiry radio wave transmitted from the tag reader is received by the antenna, it is activated, and the ID information stored in the storage unit is transmitted from the antenna as a radio wave. Such a wireless tag 1 is also referred to as an RFID, an IC tag or the like as another name.

  In the present embodiment, reception for parents and children using the lost child prevention system is established in the facility or outside the facility, and the wireless tags 1 are distributed to the parents and children who have come to this reception for the number of people. Each wireless tag 1 stores different ID information as individual identification information. Incidentally, the parent and child who have received the wireless tag 1 read the ID information of each wireless tag 1 with the tag reader of the information terminal 2, and then place the wireless tag 1 on the floor surface of their shoes, socks or trousers as much as possible. It will be used by attaching to a nearby part. For this reason, it is desirable that the information terminal 2 be installed in the vicinity of the reception. Further, the information terminal 2 is not limited to one, and a plurality of information terminals 2 may be arranged in parallel. The configuration of the information terminal 2 will be described later.

  The mobile terminal 3 is a general-purpose mobile phone equipped with an electronic mail function. The cellular phone may be one owned by the guardian himself or may be lent from the facility side to the guardian who applied for the use of the lost child prevention system. Incidentally, the guardian who applied for the use of the lost child prevention system carries the mobile phone while in the facility after inputting the e-mail address of the mobile phone to the information terminal 2.

  In consideration of the communication distance with the mobile terminal 3, the access point 4 is installed at a plurality of locations so as not to cause inability to communicate with the mobile terminal 3 carried by not only the inside of the facility but also a guardian nearby.

  The portable radio control unit 5 wirelessly transmits electronic mail data given from the management server 10 to the portable terminal 3 having the corresponding mail address from each access point 4.

  Each floor-embedded tag reader 6 reads ID information stored in the storage unit of the wireless tag 1 by non-contact communication. The wireless tag extends from the floor surface to a height of about 1 meter for each floor in the facility. In order to make it a communication area | region with 1, it is embed | buried under the floor by the space | interval of a radius of 5 meters. Each floor-embedded tag reader 6 is set with a unique reader number, and the reader information is output to the reader controller 7 with its own reader number attached to the ID information read from the wireless tag 1. .

  The reader control unit 7 controls the reading operation of each floor-embedded tag reader 6, and the ID information and reader number of the wireless tag 1 read by any one of the floor-embedded tag readers 6 are transmitted via a communication line. Transmit to the management server 10.

  The tag return box 8 is a case for returning the wireless tag 1 when a parent and child using the lost child prevention system leaves the facility, and is provided at the reception, for example. A tag reader is attached to the tag return box 8, and the ID information of the wireless tag 1 returned to the tag return box 8 is read by the tag reader. The tag return box 8 is not limited to one, and may be provided at each entrance of the facility, for example.

  The reader control unit 9 controls the reading operation of the tag reader attached to the tag return box 8, and the ID information of the wireless tag 1 read by the tag reader, that is, the ID of the wireless tag 1 returned to the tag return box 8 The information is transmitted as return tag information to the management server 10 via the communication line.

  The management server 10 is a computer that manages the reader database 11 and the tracking database 12 and can execute a management registration task, a management cancellation task, and a lost child tracking task, which will be described later, in parallel.

  As shown in FIG. 2, the reader database 11 corresponds to the reader number of each floor-embedded tag reader 6 and the place in the facility where the floor-embedded tag reader 6 specified by the reader number is embedded. Information and information of the safety leader number group are set in advance. Here, the safety leader number group is protected at a place (for example, an entrance / exit, a sales area, a stair landing, a washroom, etc.) where the floor-embedded tag reader 6 specified by the corresponding leader number is embedded. This is the reader number aggregate of the floor-embedded tag reader 6 that is buried in a safe place where it is difficult to get lost even if there is a person to be protected protected by this guardian. Here, the reader database 11 constitutes location information storage means.

  As shown in FIG. 3, the tracking database 12 includes parent ID and parent ID information, target ID as records of management numbers in the order of a series of management numbers automatically issued to the parent and child using the lost child prevention system. Records including items of information, mail address, guardian ID detection reader number, subject ID detection reader number, and tracking flag are accumulated and stored. Here, the guardian ID information is ID information of the wireless tag 1 attached to the guardian (parent), and functions as guardian identification information. The target person ID information is ID information of the wireless tag 1 attached to the protection target person (child), and functions as target person identification information. The e-mail address is an e-mail address of the mobile terminal 3 possessed by the guardian (parent). The guardian ID detection reader number is the reader number of the floor buried type tag reader 6 that has detected the wireless tag 1 having the guardian ID information, and is stored up to a predetermined number before the latest one. The target person ID detection reader number is the reader number of the floor-embedded tag reader 6 that has detected the wireless tag 1 having the target person ID information, and is stored up to a predetermined number before the latest one. The tracking flag is data for identifying whether or not to track the parent and child managed by the corresponding management number, and is set to “1” when tracking is performed. Here, the tracking database 12 constitutes registration information storage means.

  FIG. 4 is a block diagram showing a main configuration of the information terminal 2. The information terminal 2 includes at least a CPU (Central Processing Unit) 21 constituting a control unit main body, a ROM (Read Only Memory) 22 in which fixed data such as a program is stored in advance, and a RAM (Rev. Random Access Memory) 23, a communication control unit 24 for controlling data communication with the management server 10 or the like connected via a communication line, a keyboard 25 provided with keys for inputting an e-mail address, etc., with a touch panel Display 26 and tag reader 27. The tag reader 27 has an antenna 28, and can read the ID information of the wireless tag 1 brought close to the antenna 28.

  FIG. 5 is a block diagram showing a main configuration of the management server 10. The management server 10 includes at least a CPU 31 constituting a control unit body, a ROM 32 in which fixed data such as a program is stored in advance, a RAM 33 in which various data are stored in a rewritable manner, an information terminal 2 connected via a communication line, A communication control unit 34 for controlling data communication with the portable radio control unit 5 and each reader control unit 7, 9, a timer 35 for measuring time, an HDD (Hard Disk Drive) in which the reader database 11 and the tracking database 12 are stored. ) Device 36 and mail control unit 37. The mail control unit 37 creates a warning mail, which will be described later, based on a predetermined format.

  Now, in the information terminal 2, the information registration business of the parent (parent) and the person to be protected (child) is executed for a set of parent and child using the lost child prevention system. The main part processing procedure of the CPU 21 at the time of executing this information registration work is shown in the flowchart of FIG.

  That is, the CPU 21 starts this processing when the start of the information registration work is made, displays a guardian ID registration button on the touch panel display 26 as ST (step) 1, and waits for this button to be touched. To do. The start declaration of the information registration work may be determined to be made when the registration start key provided on the keyboard 25 is operated, for example, or the registration start button displayed on the touch panel display 26 is touched. When operated, it may be determined that a start declaration has been made. Alternatively, an interpersonal sensor may be provided in the information terminal 2, and it may be determined that a start declaration has been made when it is detected that the guardian stands in front of the terminal.

  When detecting that the guardian ID registration button is touch-operated in ST2, the CPU 21 gives a reading start command to the tag reader 27 in ST3 to start the reading operation of the wireless tag 1. The tag reader 27 transmits a predetermined inquiry radio wave from the antenna 28 in response to the reading start command. At this time, if the wireless tag 1 exists in the inquiry radio wave communication area, the wireless tag 1 is activated, and the ID information stored in the memory is read by the tag reader 27 by non-contact communication.

  Therefore, when detecting that the ID information of the wireless tag 1 has been read in ST4, the CPU 21 gives a reading end command to the tag reader 27 in ST5 to end the reading operation of the wireless tag 1. Next, the ID information read by the tag reader 27 as ST6 is temporarily stored in the RAM 23 as guardian ID information (identification information registration means). After that, in ST7, a protection target person ID registration button is displayed on the display 26 with a touch panel, and the touch of this button is waited for.

  Here, when it is detected in ST8 that the protection target person ID registration button has been touched, the CPU 21 again gives a reading start command to the tag reader 27 in ST9 to restart the reading operation of the wireless tag 1. If it is detected in ST10 that the ID information of the wireless tag 1 has been read, a reading end command is given to the tag reader 27 in ST11 to end the reading operation of the wireless tag 1. Next, the ID information read by the tag reader 27 as ST12 is temporarily stored in the RAM 23 as the protection target person ID information (identification information registration means). Thereafter, in ST13, a message screen for instructing the input of the mail address of the portable terminal 3 is displayed on the display 26 with the touch panel, and the input of the portable mail address is awaited.

  Here, when it is detected in ST14 that a mobile mail address has been input by a key operation of the keyboard 25, the CPU 21 temporarily stores the mobile mail address in the RAM 23 as ST15 (connection information registration means). After that, a monitoring start button is displayed on the display 26 with a touch panel as ST16, and it waits for the touch operation of this button.

  Here, when detecting that the tracking start button is touch-operated in ST17, the CPU 21 creates management registration information from the guardian ID information, the protection target person ID information and the mobile mail address temporarily stored in the RAM 23 as ST18, The data is transmitted to the management server 10 through a communication line under the control of the communication control unit 24. This completes the information registration work for a pair of parents and children using the lost child prevention system.

  Note that in the button input waiting state of ST2, ST8, ST14, or ST17, if no button touch operation or address input is performed even after a predetermined time has elapsed, this information registration operation is terminated at that point. If the ID information of the wireless tag 1 cannot be read even after a predetermined time has passed in ST4 or ST10, a read end command is given to the tag reader 27 in ST19, and then this information registration work is ended. Note that the data temporarily stored in the RAM 23 is cleared with the end of the information registration work.

  On the other hand, in the management server 10, management registration work, management cancellation work, and lost child tracking work are executed in parallel.

  FIG. 7 is a flowchart showing the main part processing procedure of the CPU 31 for the management registration work. That is, the CPU 31 stands by for receiving management registration information as ST21. As described above, the management registration information is transmitted from the information terminal 2 to the management server 10 when the information registration job is executed in the information terminal 2.

  Therefore, when receiving the management registration information from the information terminal 2 via the communication line, the CPU 31 counts up the management number counter by “1” in ST22, and the parent and child that performed necessary information registration in the information terminal 2 Issue a management number for. The management number counter is reset to “0” before opening every business day.

  When the management number is issued, the CPU 31 additionally registers a record including the management number and the guardian ID information, the protection target person ID information and the mobile mail address in the received management registration information in the tracking database 12 as ST23. To do. If the tracking flag of this record is set to “1” as ST24, the CPU 31 waits for reception of the next management registration information.

  FIG. 8 is a flowchart showing the main part processing procedure of the CPU 31 for the management cancellation work. That is, the CPU 31 waits for reception of return tag information as ST31. As described above, when the wireless tag 1 is returned to the tag reader-attached tag return box 8, the return tag information is transmitted from the reader control unit 9 to the management server 10 as return tag information including the ID information of the wireless tag 1. The

  Therefore, when receiving the return tag information from the reader control unit 9 via the communication line, the CPU 31 searches the tracking database 12 with the ID information in the return tag information as ST32. Then, only when a management number record using this ID information as the guardian ID information is detected in ST33, the tracking flag of this management number record is reset to “0” in ST34. If the ID information is not protection target person ID information, the process of ST34 is not executed. Thereafter, the CPU 31 waits for reception of the next return tag information.

  FIG. 9 is a flowchart showing the main part processing procedure of the CPU 31 for the lost child tracking operation. That is, the CPU 31 checks the management number counter as ST41. When the management number counter becomes “1”, that is, after the opening of the store every business day, when the first information registration job is executed in the information terminal 2, the following processing is repeatedly executed.

  First, in ST42, the read counter A is once initialized to “0”. Next, when the read counter A is incremented by “1” in ST43, it is determined whether or not a management number A record having the value of the read counter A as a management number is stored in the tracking database 12 in ST44. .

  Here, when the management number A record is stored in the tracking database 12, the CPU 31 checks the tracking flag of this management number A record as ST45. If the tracking flag is set to “1”, the parent and child managed by this management number are present in the facility and are monitored by the lost child. Therefore, the CPU 31 performs the parent tracking process of ST46, ST47. The protection target person tracking process and the warning determination process of ST48 are sequentially executed.

  FIG. 10 is a flowchart showing the main procedure of the guardian tracking process. That is, the CPU 31 first shifts each guardian ID detection reader number of the management number A record to the previous area as ST51, and sets the current area as an empty area. Next, the CPU 31 searches the floor-embedded tag reader 6 reading the guardian ID information of the management number A record as ST52.

  As described above, when the ID information of the wireless tag 1 is read by each floor-embedded tag reader 6, the ID information and the reader number of the tag reader 6 that has read the ID information are associated with each other via a communication line. It is transmitted to the management server 10. Therefore, the CPU 31 determines whether or not the guardian ID information exists in the ID information sent from each floor surface embedded type tag reader 6, and if it exists, the reader number associated with the ID information. , The tag reader 6 detects the floor-embedded tag reader 6 reading the guardian ID information of the management number A record.

  When detecting the floor-embedded tag reader 6 reading the guardian ID information as ST53, the CPU 31 detects the floor-buried type in the current area of each guardian ID detection reader number in the management number A record as ST54. The tag reader number of the tag reader 6 is set. On the other hand, if the corresponding floor-embedded tag reader 6 cannot be detected, the CPU 31 sets the reader number “0” in the current area of each guardian ID detection reader number in the management number A record as ST55. . Thus, the CPU 31 ends the guardian tracking process.

  FIG. 11 is a flowchart showing a procedure of the protection target person tracking process. That is, the CPU 31 first shifts each protection target person ID detection reader number of the management number A record to the previous area as ST61, and sets the current area as an empty area. Next, the CPU 31 searches the floor-embedded tag reader 6 reading the protection target person ID information of the management number A record as ST62. That is, the CPU 31 determines whether or not the protection target person ID information exists in the ID information sent from each floor surface embedded type tag reader 6, and if it exists, the reader associated with the ID information. The number tag reader 6 detects the floor buried tag reader 6 that is reading the protection target person ID information of the management number A record.

  When detecting the floor-embedded tag reader 6 reading the person-to-be-protected ID information in ST63, the CPU 31 places the floor surface in the current area of each person-to-be-protected ID detection reader number in the management number A record as ST64. The tag reader number of the embedded tag reader 6 is set. On the other hand, if the corresponding floor-embedded tag reader 6 cannot be detected, the CPU 31 sets the reader number “0” in the current area of each protection target person ID detection leader number in the management number A record as ST65. To do. As described above, the CPU 31 ends the protection target person tracking process.

  FIG. 12 is a flowchart showing the procedure of the warning determination process. That is, the CPU 31 first resets the warning flag in ST71. Next, in order to recognize the current location of the guardian managed by the management number A record, the CPU 31 acquires the leader number of the current area among the guardian ID detection leader numbers of the management number A record as ST72. Here, when the leader number of the current area is not “0” in ST73, the guardian currently has the floor-embedded tag reader 6 in which the leader number of the current area is set among the guardian ID detection leader numbers. Recognize that you are in a place where there is (location recognition means).

  Then, next, in order to recognize the present location of the protection subject protected by the guardian, the CPU 31 sets the leader number of the current area among the protection subject ID detection leader numbers of the management number A record as ST74. get. Here, when the leader number of the current area is not “0” as ST75, the protection target person is the floor buried type in which the leader number of the current area is currently set among the protection target person ID detection leader numbers. It recognizes that it exists in the place where the tag reader 6 is provided (location recognition means).

  Therefore, next, the CPU 31 searches the reader database 11 as ST76 in order to determine whether or not to issue a lost child warning depending on the location of the guardian and the guardian, and thus the guardian ID detection leader number of the current area, that is, Data of a safety reader number group for the tag reader 6 that has detected the guardian ID information is acquired. Then, it is checked whether or not the protection target person ID detection reader number of the current area, that is, the reader number of the tag reader 6 detecting the protection target person ID information, exists in the safety reader number group (warning determination). means).

  As a result, when the protected person ID detection leader number of the current area exists in the safety leader number group as ST77, the relationship between the current location of the guardian and the location of the guardian is Since there is a difficult relationship, the CPU 31 ends the warning determination process without setting the warning flag.

  On the other hand, when the protection target person ID detection leader number of the current area exists in the safety leader number group in ST77, the relationship between the current location of the guardian and the location of the protection target person is lost. In ST78, the CPU 31 instructs the mail control unit 37 to create a text e-mail for notifying the guardian of the lost child warning in ST78. At this time, the embedded location information corresponding to the protection target person ID detection reader number in the current area is incorporated in the text of the mail. If the warning flag is set in ST79, the warning determination process is terminated.

  On the other hand, when the protection target person ID detection reader number in the current area is “0” in ST75, the CPU 31 detects that the protection target person ID detection reader number is continuously number of warnings Q times from ST this time as ST80. It is determined whether or not it is “0”. If the number of warnings is “0” continuously for Q times, the wireless tag 1 attached to the person to be protected has not been detected by the floor-embedded tag reader 6 for a certain period, and the person to be protected has not been detected. The CPU 31 instructs the mail control unit 37 to create a text e-mail for notifying the guardian of the lost child warning because it is in a positional relationship that is likely to get lost from the facility. Also at this time, the embedded location information corresponding to the protection target person ID detection leader number in the current area is incorporated in the text of the mail. If the warning flag is set, the warning determination process is terminated. The number of warnings Q is an integer of 1 or more and can be set arbitrarily.

  If the guard ID detection leader number in the current area is “0” in ST73, the CPU 31 sets the guard ID detection leader number in ST81 to “0” continuously for the number of warnings P from this time. It is judged whether it was "." When the warning count P is “0” continuously, the wireless tag 1 attached to the guardian is not detected by the floor-embedded tag reader for a certain period of time, so that the guardian Since it is considered that the user has left the facility without returning it, the CPU 31 instructs the mail control unit to create a text e-mail for notifying the guardian of a call warning to the mail control unit in ST82. If the warning flag is set in ST83, the warning determination process is terminated. The number of warnings P is an integer of 1 or more and can be set arbitrarily.

Returning to FIG.
When the warning determination process of ST48 is completed, the CPU 31 determines whether or not a warning flag is set in ST49. If the warning flag is set, a warning mail is transmitted, so the CPU 31 acquires a mobile mail address from the management number A record as ST50. Then, a warning mail created by the warning determination process, that is, a lost child warning mail or a call warning mail is transmitted from the access point 4 to the mobile mail address via the portable wireless control unit 5 (lost child warning means).

  Thereafter, the CPU 31 returns to the process of ST43, further increments the read counter A by “1”, and executes the processes after ST44 again. If the tracking flag F of the management number A record has been reset to “0” in ST45, and if the warning flag has not been set in ST49, the process returns to ST43 at that time and read. The counter A is further incremented by “1”, and the processing after ST44 is executed again.

  If the management number A record is not stored in the tracking database 12 in ST44, the process returns to ST42, the read counter A is initialized to “0”, and the processes after ST43 are executed again.

  In a large supermarket where a lost child prevention system having such a configuration is constructed, it is recommended that customers with parents and children use the lost child prevention system. And the parent and child who decided to use offer to the exclusive reception. Then, since the wireless tags 1 are distributed to the parent and child by the number of persons, the parental guardian operates the information terminal 2 placed near the reception to register necessary information.

  First, the radio tag 1 worn by the guardian is brought close to the antenna 28 and the guardian ID registration button is operated. Then, the ID information of the wireless tag 1 is registered as guardian ID information. Next, the wireless tag 1 worn by the child protection subject is brought close to the antenna, and the protection target ID button is operated. Then, the ID information of the wireless tag 1 is registered as protection target person ID information. Next, when the keyboard 25 is operated to input the mail address of the portable terminal (mobile phone) 3 carried by the guardian, the tracking start button is operated. Then, this mobile mail address is associated with the guardian ID information and the protection target person ID information and registered in the tracking database 12 of the management server 10.

  Thereafter, the parent and child put the wireless tag 1 on a site within 1 meter from the floor, such as shoes, socks, and trousers, and then shop in the store. By doing so, the ID information of the wireless tag 1 attached to each of the parent and the child is read by the floor-buried tag reader 6 corresponding to each location.

  For example, assume that the data shown in FIG. At this time, if both the parent and child are in the 1st floor front section, the ID information of the wireless tag 1 attached to the parent and the ID information of the wireless tag 1 attached to the child are both the reader number “4”. ”Is read by the tag reader 6. In this case, since the reader number “4” is set in the safety radar number group for the tag reader 6 with the reader number “4”, the lost child warning is not notified.

  On the other hand, if the parent is in the first floor of the first floor sales floor and the child goes up the stairs from the first floor to the second floor, the ID information of the wireless tag 1 attached to the parent is the reader number “ 4 ”is read by the tag reader 6, but the ID information of the wireless tag 1 attached to the child is read by the tag reader 6 having the reader number“ 5 ”. In this case, since the reader number “5” is not set in the safety radar number group for the tag reader 6 with the reader number “4”, a lost child warning is notified.

  That is, a text e-mail for notifying the guardian of the lost child warning is sent to the portable terminal 3 carried by the parent. This e-mail includes information “1st and 2nd floor stair landing” where the person to be protected is embedded in the tag reader 6 with the reader number “5”. It is in the vicinity of the landing of the staircase between the second floor and the second floor, and it can be grasped that it is easy to get lost.

  As described above, according to the present embodiment, it is possible to easily specify the location of the guardian wearing the wireless tag 1 and the location of the person to be protected in the facility. Then, when there is a relationship that is likely to be lost due to the relationship between the locations of the two, the guardian can be automatically notified of the lost child warning. Therefore, a highly reliable lost child prevention system can be operated.

  In this case, it is not necessary to store personal information such as a telephone number or a mail address in the wireless tag 1 attached to each of the guardian and the guardian. Therefore, it is practical and meaningful from the viewpoint of personal information protection.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.

  For example, in the above-described embodiment, the reader database 11 is provided in a safe place where the person to be protected is unlikely to get lost when there is a guardian at each place where each tag reader 6 is provided. Although the reader number of the tag reader 6 is stored, the reader number of the tag reader 6 provided in a dangerous place where the person to be protected is likely to get lost when there is a guardian in the place, is protected. A lost child warning may be issued when the installation location of the tag reader that has received the identification information of the person to be protected is a dangerous location that is likely to be lost.

  In addition, a distance between the installation location of the tag reader 6 that reads the guardian ID information and the installation location of the tag reader 6 that reads the protection subject ID information is calculated, and if this distance exceeds a certain value, a lost child warning is obtained. May be issued. For example, when the (X, Y, Z) coordinates of the reference point in the facility are (0, 0, 0), the embedment location of each tag reader 6 is represented by (X, Y, Z) coordinates and set in the reader database 11. By doing so, the distance between the reader installation locations can be easily calculated.

  In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, the constituent elements over different embodiments may be combined.
