Description

  The present invention relates to a position monitoring system, a position monitoring apparatus, a position monitoring method, and a mobile terminal, and more particularly, to a position monitoring system, a position monitoring apparatus, a position monitoring method, and a mobile terminal for ensuring the safety of a child who is out.

  In recent years, crimes such as taking away children on the way home from schools and private schools and kidnapping cases have increased rapidly, and the environment surrounding children has deteriorated. Under such circumstances, the child has a mobile phone terminal with a built-in GPS positioning function and an effort to strengthen the child's surveillance system around the area by the patrol of the guard, and the location of the child when the parent is out Measures to prevent children from getting involved in incidents, such as providing services that can be confirmed, are strongly desired.

  In particular, a child monitoring system using a mobile terminal with a built-in GPS positioning function has been well known as an effective monitoring system due to recent improvements in GPS positioning functions. An example of such a monitoring system is disclosed in Japanese Patent Laid-Open No. 2006-171970 (Patent Document 1).

  The technique disclosed in Japanese Patent Application Laid-Open No. 2006-171970 is a monitoring system for ensuring the safety of children, and includes a portable mobile terminal provided to a child and a regional terminal installed in the region. I have. The mobile terminal stores monitoring range information set by a guardian such as a parent, and monitors the location of the terminal itself using a built-in GPS positioning function. When the position of the terminal is out of the range defined by the monitoring range information, a notification signal is transmitted to that effect and the position information of the terminal is transmitted to the mobile phone terminal possessed by the parent. The notification signal transmitted from the mobile terminal is received by a regional terminal installed in the vicinity. The regional terminal that has received the notification signal notifies the supervisor of the regional terminal of the presence of a child such as a lost child by issuing an alarm sound. The supervisor of the regional terminal performs a transmission operation of a response signal to the notification signal in order to find a child. When the response signal is received, the mobile terminal that has transmitted the notification signal sounds an alarm sound with the built-in speaker. A warning sound is emitted from the mobile terminal possessed by the child, so that the surrounding people can easily find the child.

  Japanese Patent Application Laid-Open No. 2004-227384 discloses a technique for monitoring an unexpected movement of a movable object using a mobile terminal incorporating a GPS positioning function, which is not a child monitoring system but can be applied as a child monitoring system. It is disclosed in the gazette (patent document 2).

  The technique disclosed in Japanese Patent Application Laid-Open No. 2004-227384 is a mobile phone terminal held by an owner when a movable object such as a car or a bag moves due to theft or the like regardless of the intention of the owner. This is a system that directly reports to that effect, and is characterized by notifying without passing through a third party such as an alarm center or a service center. The slave unit having the GPS positioning function monitors the storage of the initial position information and the subsequent position movement in accordance with an instruction from the mobile phone terminal of the owner of the movable object that is the master unit. The child device that has detected that it has moved a certain distance from the initial position calls the parent device via the mobile phone line, and notifies the responding parent device of the moved position and the alarm signal.

  In addition, before 2000 when SA (Selective Availability), which is a measure for intentionally reducing the positioning accuracy of GPS, is cancelled, the positioning accuracy of GPS cannot be expected, and therefore, Japanese Patent Laid-Open No. 7-298350 ( As disclosed in Japanese Patent Application Laid-Open No. 2000-287265 and Japanese Patent Application Laid-Open No. 2000-287265 (Patent Document 4), the present invention relates to a lost child prevention device or a leftover prevention device that identifies the positional relationship between mobile terminals using received electric field strength. There was technology. According to these publications, the master unit measures the received electric field strength of the radio wave emitted from the slave unit. Then, in the master unit that has identified that the mutual distance between the master unit and the slave unit is more than a certain distance, an indication or warning to that effect has been issued, the accompanying child has left, and the belongings have been dropped. It is to inform you that it has been.

Can receive the notification and know the location of the child device. In particular, the technique disclosed in Japanese Patent Application Laid-Open No. 2006-171970 is effective in terms of being able to ask for support from surrounding people. However, in such a conventional monitoring system, the parents are not always relieved.

  Because even if the parent knows where the child is, he only knows the fact that he is there and is more worried about whether the child is in a safe situation or not. Therefore, if the child device possessed by the child is a mobile phone terminal, further actions such as making a call to confirm the situation are required. In addition, although the technology disclosed in Japanese Patent Application Laid-Open No. 2006-171970 is able to seek support from the people around it, the people are only third parties, so it is not always safe as a parent's feelings. There should be no.

  Further, when the mutual distance between the master unit and the slave unit is more than a certain distance as in the techniques disclosed in JP-A-7-298350 and JP-A-2000-287265, the master unit is notified to that effect. It is premised that both of them are acting together. Therefore, it is not effective in a situation where a person having a terminal to be monitored does not always act with a person having a terminal to be monitored. Also, there was no way to confirm the unidentified location of the monitored person even if the person who accompanied the action was accompanied.

  The present invention solves the problems that cannot be solved by the conventional monitoring system as described above, and can truly relieve the parent, a position monitoring system and position monitoring for ensuring the safety of children on the go An apparatus, a position monitoring method, and a mobile terminal are provided.

  FIG. 1 is a network configuration diagram showing the overall configuration of the first embodiment of the present invention.

  In FIG. 1, a monitoring apparatus 101 according to the present invention is installed in a network 100. The network 100 is based on a mobile communication network, and the monitoring device 101 may be installed along with a device constituting the ground network of the mobile communication network, or installed on the Internet connected to the mobile communication network. May be.

  The mobile terminal 301 is a mobile terminal to be monitored, and the mobile terminal 302 is a person related to the person holding the mobile terminal to be monitored, for example, a child of a group who goes to and from school together, It is a mobile terminal held by a child, another child's parent, a school teacher, or the like. Each mobile terminal 301, 302 has a communication function with the monitoring device 101 via a mobile communication network and a GPS positioning function. Each mobile terminal 301, 302 receives radio waves from GPS satellites 201 to 203 according to positioning start conditions described later, measures the latitude and longitude of the location where it is located, and reports the measurement results to the monitoring device 101. . The mobile terminals 301 and 302 are desirably mobile phone terminals having a GPS positioning function, but are not limited thereto.

  When the abnormal state of the mobile terminal 301 to be monitored is identified, the terminal 401 is a notification destination terminal that notifies that fact. A mobile phone terminal is desirable from the viewpoint of receiving notification of an abnormal state, but it may be a PC (personal computer) capable of IP communication via the Internet.

  The first embodiment configured as described above sets a monitoring condition in the monitoring device 101, monitors a mobile terminal to be monitored in accordance with the monitoring condition, and identifies an abnormal state in the terminal 401. Notice. The monitoring condition is set and changed by a person who has authority to set and change the monitoring condition.

  First, monitoring conditions set in the monitoring apparatus 101 will be described.

  FIG. 2 is a block configuration diagram showing the configuration of the monitoring apparatus 101 according to the present invention.

  In FIG. 2, the communication unit 110 manages communication with the mobile terminals 301 and 302 and the terminal 401 via the network 100. The monitoring data storage unit 120 stores monitoring conditions set by operations described later as monitoring data for each mobile terminal to be monitored. The position search unit 120 compares the position information received from the mobile terminals 301 and 302 with the monitoring conditions stored in the monitoring data storage unit 120, and outputs the presence / absence of an abnormal state. The control unit 140 is a control device such as a CPU (Central Processing Unit), sets monitoring data in the monitoring data storage unit 120, obtains a search execution instruction and a search result for the position search unit 130, and communicates via the communication unit 110. It controls overall control operations of the monitoring apparatus 101 such as communication control with the mobile terminals 301 and 302 and the terminal 401. The CPU controls the control operation by reading and executing a program stored in a memory such as a ROM (Read Only Memory) (not shown).

  Parents and other guardians can set and change conditions for monitoring children's behavior by accessing the monitoring device 101. The terminal used for setting the monitoring conditions may be a mobile phone terminal or a PC. By accessing the monitoring apparatus 101, the setting condition for monitoring instructed from the monitoring apparatus 101 is input.

  FIG. 3 is an example of data content showing an example of the content of the monitoring data set in the monitoring data storage unit 120 of the monitoring device 101.

In the monitoring data, monitoring condition data and notification destination information are set corresponding to the mobile terminal 301 to be monitored. First, the monitoring terminal information 121 of the mobile terminal 301 to be monitored is set. And as corresponding monitoring condition data, area information 122 for specifying the monitoring area, time information 123 for specifying the monitoring time, related terminal information 124 for specifying the related mobile terminal 302 accompanying the monitoring terminal in the monitoring area, In addition, the allowable distance information 125 between the mobile terminal 301 to be monitored and the related mobile terminal 302 is set. The notification destination information 126 is information for specifying a notification destination to notify that when an abnormal state occurs in the monitored action.
The monitoring terminal information 121 and the related terminal information 124 are set using a telephone number, but the monitoring apparatus 101 corresponds to the telephone number by referring to a database (not shown) managed in the mobile communication network after the setting is completed. The terminal identification information (terminal ID assigned to the terminal) is acquired separately and managed together with the telephone number.

  The area information 122 sets a normal movement route of the mobile terminal 301 to be monitored. For example, it is possible to arbitrarily set a predetermined action route such as when going to school, leaving school, or going to a cram school, a play place with a friend in a park or the like, or going out. In the setting, the terminal used for setting the monitoring condition is set by plotting the route on the map displayed from the monitoring device 101. The monitoring device 101 stores the start point and the end point plotted on the map and the route between them in association with a plurality of latitude and longitude information.

  The time information 123 specifies the start and end of monitoring and the monitoring interval time between them. For example, if it is “at the time of school attendance”, the time of leaving home every morning and the time of arrival at school and the interval between them will be monitored at intervals of 5 minutes. Specify to monitor at minute intervals. In particular, as the end time, a time sufficient to reach the destination is set, and if the destination is not reached even after the set time has elapsed, it is regarded as one element of an abnormal state. As described above, the time information 123 can be appropriately specified according to the behavior pattern.

  The related terminal information 124 sets the telephone number of the mobile terminal 302 that accompanies the current behavior of the mobile terminal 301 to be monitored. For example, the telephone number of the mobile terminal held by each group member at the time of attending school, leaving school, or a play friend when playing in a park is set.

  The permissible distance information 125 defines the permissible distance between the monitored mobile terminal 301 and the related mobile terminal 302. The monitoring apparatus 101 calculates the distance between the mobile terminal 301 to be monitored and the related mobile terminal 302, and identifies whether it is within the set allowable distance. When the allowable distance is exceeded, it is considered as one element of abnormal state. If this allowable distance is not set, if the distance between the monitored mobile terminal 301 and the related mobile terminal 302 is, for example, within 10 meters as a default value, the related mobile terminal 302 is monitored. It is determined that it exists in the vicinity. The permissible distance information 125 can be used as a parameter that is arbitrarily set according to the action pattern, such as 5 meters when going out in a crowd in the city and 20 meters when playing in a park.

  The notification destination information 126 sets at least the telephone number and email address of the parent of the child holding the mobile terminal 301 to be monitored. Depending on the behavior pattern, a school teacher or a friend's parent can be additionally set.

  FIG. 4 is a block diagram showing the structure of the mobile terminals 301 and 302 according to the present invention. In this embodiment, the mobile terminals 301 and 302 are mobile phone terminals having a GPS positioning function, but in FIG. 4, the monitoring device 101 is connected via the GPS unit 320 that performs GPS positioning according to the present invention and the mobile communication network. Only the communication unit 310 that communicates with the control unit 330 and the control unit 330 that executes various types of control described below according to the present invention are illustrated.

  Next, the operation of the first embodiment of the present invention will be described with reference to FIG. FIG. 5 is a flowchart for explaining the control operation in the monitoring apparatus 101 according to the first embodiment of the present invention.

  Based on the monitoring data stored in the monitoring data storage unit 120, the monitoring apparatus 101 monitors the monitoring time for each registered mobile terminal 301 to be monitored (S501). When the monitoring start time or the monitoring interval time set in the monitoring condition data is reached (S502: Yes), a positioning instruction signal is sent to the monitoring target mobile terminal 301, and the position information measured by the mobile terminal 301 is moved. Received and acquired by a response signal from the terminal 301 (S503). At this time, by including the terminal ID of the monitoring target mobile terminal 301 managed together with the telephone number in the positioning instruction signal, it is possible to specify the mobile terminal that is the target of the positioning instruction. On the other hand, the position information corresponding to the mobile terminal 301 instructed for positioning is identified by the terminal ID included in the response signal from the mobile terminal 301.

  Subsequently, in the position search unit 130, the monitoring apparatus 101 compares the area information 122 set in the monitoring condition data with the position information received from the mobile terminal 301, and the position of the mobile terminal 301 is the position on the normal route. It is determined whether or not (S504). At this time, the error between the position specified from the latitude and longitude information set as the area information 122 and the position based on the position information received from the mobile terminal 301 is in the horizontal direction (90 degrees left and right with respect to the traveling direction). 10m is acceptable.

  In this normal route determination, when it is determined that the normal route is deviated (S504: No), the monitoring device 101 is accompanied by the mobile terminal 301 set in the related terminal information 124 of the monitoring condition data. The mobile terminal 302 identification information is sent, a positioning instruction signal is sent to the accompanying mobile terminal 302, and the location information measured by the mobile terminal 302 is received as a response signal from the mobile terminal 302, Obtain (S505). Also in this case, the mobile terminal 302 is designated by the terminal ID of the accompanying mobile terminal 302, and the position information corresponding to the mobile terminal 302 instructed by the terminal ID included in the response signal from the mobile terminal 302 is obtained. Identify. When there are a plurality of mobile terminals set in the related terminal information 124 of the monitoring condition data, a positioning instruction signal is transmitted to all the mobile terminals, and position information is acquired from all the mobile terminals.

  Subsequently, the monitoring apparatus 101 calculates the distance between the two based on the position information of the monitoring target mobile terminal 301 and the position information of the accompanying mobile terminal 302 (S506). As a result of the distance calculation, it is identified whether or not both are located within the distance set as the allowable distance 125 of the monitoring condition data (S507). When the allowable distance 125 is not set in the monitoring condition data, the positional relationship between the two is determined based on a default value (for example, 5 meters).

  As a result, when it is identified that the monitored mobile terminal 301 is away from the accompanying mobile terminal 301, the monitored mobile terminal 301 leaves the normal route and is also away from the accompanying mobile terminal 302. It is determined that the person is in an abnormal state (S507: No), and the occurrence of the abnormal state is notified to the notification destination set in the notification destination information 126 of the monitoring condition data (S510). This notification sends a message call to notify the abnormal state to the telephone number set in the notification destination information 126 of the monitoring condition data, and attaches map information identifying the location where the abnormal state has occurred to the e-mail address. By sending an email.

  In S504, if the normal route is found (S504: Yes), or if the mobile terminal 302 that accompanies in S507 is identified in the vicinity even if the normal route is off (S507: Yes), the monitoring process is performed. continue. If the continuous monitoring process identifies that the mobile terminal 301 has reached the destination (S508: Yes), the monitoring process ends. In other words, if the position information reported by the mobile terminal 301 is the position information corresponding to the monitoring end point set in the area information 122 of the monitoring condition data by continuous monitoring, the mobile terminal 301 reaches the destination. Judge that

  If the destination has not been reached in the processing of S508 (S508: No), the monitoring end time set in the time information 123 of the monitoring condition data is compared with the current time (S509).

  Since the monitoring end time is set to a time sufficient for the mobile terminal 301 to reach the destination, the abnormal state from the viewpoint of the passage of time is identified. That is, even when the mobile terminal 301 is located on the normal route but does not reach the destination within the monitoring end time (S509: Yes), it is determined as an abnormal state due to some factor. Even when this abnormal state is determined, the notification process of S510 is executed, a message call for notifying the abnormal state is sent to the telephone number set in the notification destination information 126 of the monitoring condition data, and the e-mail address is also sent. Send an email with map information identifying the location where the abnormal condition occurred (location information received when the abnormal condition is determined).

  If the monitoring end time has not elapsed (S509: No), the process returns to S501 to check the time until the next monitoring time is reached, and the above-described processing is repeated.

  The first embodiment has been described above with reference to the flowchart shown in FIG. 5, but the following modifications and application examples can also be applied.

  First, in the determination processing of S509, when the mobile terminal 301 is located on the normal route but does not reach the destination within the monitoring end time, the location information of the accompanying mobile terminal 302 is specifically identified. Not like that. However, in this case as well, the monitoring apparatus 101 transmits a positioning instruction signal to the accompanying mobile terminal 302 to acquire the position information, and in the notification processing of S510, the position information of the accompanying mobile terminal 302 and the movement of the monitoring target The position information of both the position information with the terminal 301 may be included in the notification information.

  Further, following the processing of S503, a positioning instruction may be issued to all related mobile terminals including the accompanying mobile terminal 302 set in the related terminal information 124 of the monitoring condition data at this time. That is, in the flowchart shown in FIG. 5, the process of S505 may be performed after the process of S503. If such processing is performed, the location information and monitoring target of the accompanying mobile terminal 302 are not included in the notification processing of S510 even if the location information acquisition processing of the accompanying mobile terminal 302 is not performed after the determination processing of S509. Both pieces of position information of the position information with the mobile terminal 301 can be included in the notification information.

  Further, in the processing of S510, at the same time notifying the occurrence of an abnormal state to the notification destination set in the notification destination information 126 of the monitoring condition data, simultaneously from the monitoring device 101 to the monitoring target mobile terminal 301 and the accompanying mobile terminal 302, Each terminal ID may be specified to transmit an alarm signal, and the mobile terminal 301 or 302 that has received the alarm signal may emit an alarm sound.

  As described above, in the first embodiment of the present invention, the mobile terminal 301 to be monitored leaves the set route, and there is no accompanying person and the monitoring end time has elapsed. Even when the destination is not reached, it is determined as an abnormal situation, and only in such a case is notified to a preset notification destination. Therefore, since only a really urgent state is notified, the parent of the child carrying the monitoring target mobile terminal 301 set as the notification destination is the monitoring target mobile terminal 301 or the accompanying mobile terminal 302. You can immediately check the situation and take necessary measures by calling. In addition, when an alarm sound is generated in the mobile terminals 301 and 302, the accompanying mobile terminal 302 owner immediately notices that the mobile terminal 301 to be monitored is not in the vicinity for early detection. Measures can also be taken.

  Next, a second embodiment according to the present invention will be described. In the second embodiment, a parent terminal set among related mobile terminals grasps the mutual positional relationship, and notifies a predetermined terminal when an abnormal state is identified. This is an embodiment in which no device is installed. This embodiment is suitable for behavior monitoring in a form in which a senior student who is a leader holds a parent terminal and leads a junior student in a small group such as a group attending school.

  Although the mobile terminal 601 (parent terminal) is assumed to be a mobile phone terminal, in FIG. 7, a GPS unit 620 that performs positioning by GPS according to the present invention, a communication unit 610 that communicates with the terminal 401 via a mobile communication network, A short-range wireless communication unit 640 represented by Bluetooth, a memory 660 for storing monitoring condition data and positioning information, a timer 650 for measuring time, a speaker 670 for generating an alarm, a display unit 680 for performing various displays, and the present invention Only the control unit 630 that executes various controls described later is shown. The control unit 630 is a control device such as a CPU (Central Processing Unit) and controls a control operation by reading and executing a program stored in a memory such as a ROM (Read Only Memory) (not shown).

  The mobile terminal 602 has the same configuration, but the GPS unit 620 may not be provided.

  FIG. 8 shows a content information example (a) of monitoring condition data in the present embodiment, which is stored in the memory 660 of the mobile terminal 601 (parent terminal), and a positioning information storage example in which positioning data is stored in time series ( b).

  Unlike the monitoring data in the first embodiment shown in FIG. 3, in this embodiment, the monitoring condition data is stored in each mobile terminal. The individual information fields are almost the same as the information fields described in FIG.

  The area information 801 shown in FIG. 8A is information for specifying the monitoring area, the related terminal information 802 is information for specifying the mobile terminal 602 of the child terminal accompanying the mobile terminal 601, and the notification destination information 803 is the monitoring destination information 803. This is information for specifying a notification destination to notify when an abnormal state occurs in the action being performed.

  Area information 801 sets a normal movement route of the mobile terminal 601. For example, a predetermined action route such as when going to school or leaving school is set. In setting, a map of the monitoring target area downloaded separately from the map server, PC, or the like to the mobile terminal 601 is displayed and set by plotting the route on the map. The mobile terminal 601 stores the start point and end point plotted on the map and the route between them as area information 801 in association with a plurality of latitude and longitude information.

  The related terminal information 802 sets identification information of the short-range wireless communication unit 640 of the mobile terminal 602 that is a child terminal that accompanies the behavior of the mobile terminal 601 of the parent terminal. In setting, the communication establishment setting by the short-range wireless communication with the mobile terminal 602 is set in advance, and is set as the identification information of the short-range wireless communication unit 640 capable of communication at that time. The telephone number of the mobile terminal 602 is also set in correspondence with this identification information (short-range wireless ID). It is also possible to set the name of the child holding the child terminal.

  The notification destination information 803 sets the telephone number and email address of the parent of the child holding the mobile terminal 601. You can also add school teachers and friends.

  The mobile terminal 601 for which the above-described monitoring condition data has been set in advance and the mobile terminal 602 which is a child terminal thereof are given to the child when going to and from school.

  Next, the operation of the second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a flowchart for explaining a control operation in the mobile terminal 601 in the second embodiment of the present invention.

  First, the monitoring application program of the mobile terminal 601 is activated (S901). This activation is premised on an operation by the holder of the mobile terminal 601, but it may be a timer activation based on a preset time or may be separately activated by a remote operation from a mobile phone terminal held by a guardian. Further, a master device (not shown) that performs short-distance communication with the mobile terminal 601 to be held by the child is always installed in a school, a cram school, or at home, and the mobile terminal 601 is connected to the master device. You may make it identify that it left | separated from a school, a cram school, or a home by having cut | disconnected near field communication, and may start a monitoring application program on that occasion. In this case, it is desirable that the short-range communicable range between the mobile terminal 601 and the master device is 10 to 50 meters.

  When the monitoring application program is started, positioning by the GPS satellites 201 to 203 is performed in the GPS unit 620 by the programmed periodic operation, and the latitude and longitude information of the positioning result is sequentially stored in the memory as shown in FIG. 8B. (S902). Further, the short-range wireless communication unit 640 communicates with the surrounding mobile terminal 602 to acquire the short-range wireless ID (S903).

  When the above operation is completed, the monitoring condition data set in the memory 660 is referred to and it is determined whether or not the measured position information is within the range set in the area information 801 (S904). At this time, the error between the position specified from the latitude and longitude information set as the area information 801 and the position measured is allowed to be about 10 meters in the lateral direction (90 degrees to the left and right with respect to the traveling direction).

  If it is determined that the route is not deviated from the normal route (S904: Yes), the short-range wireless ID of the peripheral mobile terminal 602 set in the related terminal information 802 of the monitoring condition data and the peripheral mobile terminal 602 acquired by the processing of S903 are displayed. The short-range wireless IDs of the short-range wireless communication units 640 are compared to confirm the presence of all the surrounding mobile terminals 602 (S905).

  In the process of S905, the presence of all the surrounding mobile terminals 602 is confirmed (S905: Yes). If the destination has not yet been reached (S906: No), the process returns to the process of S902 and the next cycle. Repeat positioning by movement.

  On the other hand, when comparing the short-range wireless ID of the peripheral mobile terminal 602 set in the related terminal information 802 of the monitoring condition data in the confirmation processing of S905 and the short-range wireless ID of the mobile terminal 602 acquired in the processing of S903, When it is identified that the short-range wireless ID has not been acquired from all the surrounding mobile terminals 602 (S905: No), a first alarm is issued from the speaker 670 (S907). The first alarm is an alarm notifying that the mobile terminal 602 that is a child terminal to accompany is not in the vicinity. At this time, the identification information of the mobile terminal 602 that is not in the vicinity is displayed on the display unit 680. The identification information displayed at this time is preferably the name of the child holding the child terminal and the telephone number of the mobile terminal 602 set in correspondence with the short-range wireless ID.

  With this first alarm, it is possible to immediately confirm the presence of a child who has left the group, and if the child can be found within the viewing distance, the child can be returned to the group. Even if it cannot be found within the viewing distance, by making a call using the telephone number of the mobile terminal 602 displayed on the display unit 680, it is possible to immediately contact the unknown person, You can easily return to the group.

  If the destination has not yet been reached after issuing the first alarm (S906: No), the process returns to the process of S902 to repeat positioning in the next periodic operation.

  If it is determined in step S904 that the route is out of the normal route (S904: No), the short-range wireless ID of the surrounding mobile terminal 602 set in the related terminal information 802 of the monitoring condition data and the processing in step S903 are acquired. The short-range wireless IDs of the mobile terminals 602 are compared to confirm the presence of all the surrounding mobile terminals 602 (S908).

  If the presence of all the surrounding mobile terminals 602 is confirmed in the processing of S908 (S908: Yes), a second alarm is issued from the speaker 670 to notify that the normal route is off (S909). At this time, the display unit 680 displays the normal route and the current position information together with the map.

  Although such a situation is unlikely to occur in the daily route to and from school, it is effective for behavior monitoring when the purpose of use is hiking or going out, and children go to a land that is small in groups and is not familiar with geography. This second alarm can immediately return to the original normal route.

  If the destination has not yet been reached after issuing the second alarm (S906: No), the process returns to the process of S902 and the positioning in the next periodic operation is repeated.

  Furthermore, when it is determined that the route is out of the normal route in the process of S904 (S904: No), and it is determined in the process of S908 that all the surrounding mobile terminals 602 are not present (S908: No), the route is removed from the normal route. It is determined that there is an abnormal state in which the person has been disconnected and has become only one person, and an abnormality notification is sent to the notification destination set in the notification destination information 803 of the monitoring condition data (S910). This abnormality notification transmits an e-mail with a content notifying that an abnormal state is attached, with a map attached by plotting a route based on the positioning information accumulated since the monitoring application program is started. The display unit 680 of the mobile terminal 602 displays an alarm message explaining a coping method such as telephone contact with the parent.

  If it is determined in the determination processing of S906 that the position information of the measured location is the route end point set in the area information 801 of the monitoring condition data, it is determined that the destination has been reached (S906: Yes) and the monitoring application Ends program processing.

  In the second embodiment described above, the control operation of the mobile terminal 601 that is the parent terminal has been mainly described. However, the mobile terminal that is a child terminal that always communicates with the mobile terminal 601 by short-range wireless communication. The control operation as shown in FIG.

  FIG. 10 is a flowchart for explaining the operation of the monitored application program executed in the child terminal accompanying the parent terminal as an application example in the second embodiment.

  The mobile terminal 602, which is a child terminal, is provided with an alarm generation function, and an alarm is issued at the child terminal when the child terminal is away from the parent terminal.

  First, the monitored application program of the mobile terminal 602 is activated (S1001). This activation is premised on an operation by the holder of the mobile terminal 602, but it may be a timer activation based on a preset time or may be separately activated by a remote operation from a mobile phone terminal held by a guardian. In addition, a master device (not shown) that performs short-range communication with the mobile terminal 602 that the child has at all times is installed in a school, school, home, etc., and the mobile terminal 602 is connected to this master device. You may make it identify that it left | separated from a school, a cram school, or a home by having cut | disconnected near field communication, and may start a monitoring application program on that occasion. In this case, it is desirable that the short-range communicable range between the mobile terminal 602 and the master device is 10 to 50 meters.

  When the monitored application program is started, the communication is established by acquiring the short-range wireless ID on the mobile terminal 601 side during communication with the short-range wireless communication unit of the mobile terminal 601 that is the parent terminal (S1002). (S1003: Yes). This operation is repeated until the application program ends (S1004: No).

  If the process of S1003 leaves the mobile terminal 601 and communication with the mobile terminal 601 cannot be established, and the short-range wireless ID on the mobile terminal 601 side cannot be acquired (S1003: No), the third Is issued (S1005). The third warning is to warn the holder of the mobile terminal 602 that the user has left the group. At this time, the telephone number of the parent terminal may be displayed on the display unit.

  If there is a group within the viewing distance, it is possible to return to the group immediately. Even if the group is not found within the viewing distance, it is easy to contact the leader of the group by making a call using the phone number of the parent terminal displayed on the display. You can go back to the group.

  As described above, in the second embodiment of the present invention, the first alarm is issued when it is identified that the child terminal that accompanies in the middle of the normal route has left the group. With this first alarm, it is possible to immediately confirm the presence of a child who has left the group and return the child to the group. If the group's action route deviates from the normal route and the accompanying child terminal is in the vicinity, a second alarm is issued. At this time, since the normal route and the current position information are displayed on the display unit together with the map, it is possible to immediately return to the original normal route by this second alarm. When an abnormal state in which the route is off the normal route and only one person is identified, an abnormality notification is sent to a preset notification destination such as a parent. This abnormality notification is an e-mail with contents indicating that it is in an abnormal state, to which a map showing the past action paths is attached. In addition, an alarm message explaining a coping method such as telephone contact with the parent is displayed on the display unit. Thereby, even if an abnormal state occurs, accurate communication and necessary measures can be taken.

  Next, a third embodiment according to the present invention will be described. In the third embodiment, the parent terminal set among the related mobile terminals grasps the mutual positional relationship, and when the abnormal state is identified, the parent terminal copes with the monitoring device installed in the network. It is embodiment which asks for assistance. This embodiment is suitable for behavior monitoring in such a way that teachers and other leaders hold the parent terminal and lead many students when acting in large groups at school events such as excursions and social tours.

In the mobile terminal information 1403, the telephone numbers of the parent terminal 801 (0) and the child terminals 801 (1) to 801 (n) constituting the mobile terminal group 800, the names of the holders, and the like are registered. Identification information (mobile terminal ID) of each mobile terminal acquired separately is also included. In the notification destination information 1404, a telephone number, an e-mail address, and the like that can specify the terminal 501 of the standby party are registered. Further, a password for accessing the monitoring terminal 701 from the terminal 501 during the monitoring operation may be included.

  FIG. 15 shows the positional relationship for recording the positional relationship between the monitoring condition data (a), the positioning data (b), and the child terminals 801 (1) to 801 (n) set in the memory 860 of the parent terminal 801 (0). It is an example of data content which shows an example of the content of information (c).

  In the monitoring condition data shown in FIG. 15 (a), area information 1501 specifies information for an action scheduled area, and child terminal information specifies each of the child terminals 801 (1) to 801 (n) constituting the mobile terminal group 800. Information and notification destination information 1505 is contact information of a guardian or the like of a lead person who has a child terminal, and assumes a telephone number.

  Area information 1501 sets a scheduled action route for the mobile terminal group 800. For example, if it is a school trip, a daily action route is set. In the setting, a map of the monitoring target area downloaded separately from the map server or PC to the parent terminal 801 (0) is displayed, and the route is plotted on the map. The parent terminal 800 (0) stores the start and end points plotted on the map and the route between them as area information 1501 in association with a plurality of latitude and longitude information.

  The short distance wireless ID 1502 of the child terminal information sets identification information of the short distance wireless communication unit 840 included in each of the child terminals 801 (1) to 801 (n). In setting, the communication establishment setting by short-range wireless communication with each of the child terminals 801 (1) to 801 (n) is performed in advance, and is set as identification information of the short-range wireless communication unit 840 capable of communication at that time. The telephone number 1503 of the child terminal is also set in correspondence with this identification information (short-range wireless ID).

  Note that the configurations of the child terminals 801 (1) to 801 (n) have the same configuration as that shown in FIG. 13, but it is not necessary to have the data and information shown in FIG. However, identification information of the short-range wireless communication unit 840 of each of the mobile terminals 801 (0) to 801 (n) constituting the mobile terminal group 800 is set. In the setting, communication establishment setting by short-range wireless communication with each of the mobile terminals 801 (0) to 801 (n) is performed in advance, and identification information of the short-range wireless communication unit 840 capable of communication at that time is set.

  Next, referring to FIG. 16 and FIG. 17, the mobile terminals 801 (0) to 801 (n) constituting the mobile terminal group 800 in the third embodiment of the present invention confirm the positions of the mobile terminals. The short-range wireless communication performed for the purpose will be described.

  FIG. 16 is a conceptual diagram for explaining short-range wireless communication performed for confirming the location of mobile terminals in the third embodiment of the present invention.

  FIG. 16A is a conceptual diagram schematically showing the position of each mobile terminal and an area where short-range wireless communication is possible. In FIG. 16 (a), M represents a parent terminal, a to i represent each child terminal, and circumferences 1601 to 1610 around it represent areas where short-distance wireless communication of each terminal is possible. For example, the short-range wireless communicable area of the parent terminal M is indicated by a circle 1601, the short-range wireless communicable area of the child terminal a is indicated by a circle 1602, and the short-range wireless communicable area of the child terminal b is indicated by a circle 1603. Similarly, the short-range wireless communication areas of the child terminals c to i are indicated by circumferences 1603 to 1610. As shown in FIG. 16 (a), the short-range wireless communication areas of the parent terminal M and the child terminals a to h overlap with any area, and short-range wireless communication with any terminal is possible. is there. On the other hand, the short-distance wireless communicable area of the child terminal i does not overlap with the short-distance wireless communicable area of any terminal, indicating that the child terminal i is away from other terminals. In addition, although the short-range wireless communicable area is assumed to be about 10 to 15 meters around the own terminal, it can be appropriately changed according to the behavior form.

  FIG.16 (b) is a table | surface which shows the relationship with the terminal in which the short distance wireless communication in each terminal in the condition in Fig.16 (a) is possible. For example, the parent terminal M can perform near field communication with the child terminals a, b, and c, and the child terminal a can perform near field communication with the parent terminal M and the child terminal d. In the same manner, a partner terminal of short-range wireless communication capable of each of the child terminals b to i is shown. Therefore, the child terminal i indicates that there is no partner terminal capable of short-range wireless communication as described with reference to FIG. 16 (a) and 16 (b) only illustrate the situation at a certain point in time, and the positional relationship of each terminal changes sequentially with the action.

  FIGS. 16C and 16D are schematic diagrams illustrating signal format examples in short-range wireless communication performed between terminals.

  FIG. 16C shows a format example of a response request signal. As will be described later, FIG. 16C is a signal for obtaining a response signal from a terminal that has received this signal. The terminal that transmits this response request signal includes the short-range wireless communication ID of its own terminal in the signal so that it can be identified from which terminal the received terminal has requested the response.

  The terminal that has received the response request signal performs the following two operations.

  The first operation is an operation for returning a response signal in response to the response request signal. The response signal is included in the received response request signal, as shown in FIG. 16 (d), so that it can be identified from which terminal the response signal is received from which terminal. A response signal including the short-range wireless ID that has been stored in the field of the request source ID and the short-range wireless ID of the own terminal in the response source ID is returned.

  The second operation is an operation of relaying the received response request signal. In this case, the short-range wireless ID of the own terminal is added to the short-range wireless ID included in the received response request signal and transmitted. Accordingly, in the relayed response request signal, a plurality of short-range wireless IDs are included in the request source ID. Each time relaying is performed, the request source ID sequentially includes the short-range wireless ID of the relayed terminal.

  Next, conditions for transmission / reception of the response request signal and the response signal will be described. This condition is provided so that the response request signal and the response signal are not unnecessarily transmitted and received between the terminals.

  The response request signal is transmitted for the position confirmation operation, and is periodically transmitted by the parent terminal. The response signal is finally received by the parent terminal to grasp the positional relationship between the terminals.

  The child terminal that has received the response request signal and returned the response signal in response to the response signal no longer needs to respond in the position confirmation period, and discards the response request signal received after the response signal is returned.

  On the other hand, when receiving the response signal, the request source ID is checked for the presence of the short-range wireless ID of the terminal itself. If the short-distance wireless ID of the own terminal is included in the request source ID, it is a response signal to the response request signal relayed and transmitted, and the received response signal is relayed and transmitted. That is, the operation of transmitting the same signal is performed without any processing. When the short-distance wireless ID of the own terminal is not included in the request source ID, the response signal is a response signal to the response request signal relayed by another terminal, and the response signal is discarded in the terminal.

  The outline of the position confirmation operation of each terminal using the response request signal and the response signal will be described with reference to FIG.

  FIG. 17 is a sequence diagram illustrating an outline of an operation for performing position confirmation using a response request signal transmitted from the parent terminal and a response signal returned from each terminal in the third embodiment. In FIG. 17, M represents a parent terminal, and a to i represent child terminals. Further, the positional relationship of each terminal is as described with reference to FIGS. 16 (a) and 16 (b).

  As described above, the position confirmation operation of each terminal constituting the mobile terminal group 800 is executed by the parent terminal. Then, the response request signal transmitted from the parent terminal M is received by the child terminal a, the child terminal b, and the child terminal c that exist in an area where the parent terminal M can perform near field communication. The operations at the child terminal a, the child terminal b, and the child terminal c from which the response request signals are received will be sequentially described.

  Receiving the response request signal (s1700) transmitted from the parent terminal M, the child terminal a returns a response signal (s1701) including “M” as the request source ID and “a” as the response source ID. This response signal (s1701) is received by the parent terminal M. “M” and “a” are short-range wireless IDs of the parent terminal M and the child terminal a, respectively. The same applies to the following description.

Further, the child terminal “a” adds the short-range wireless ID “a” of its own terminal to the request source ID of the response request signal received from the parent terminal M, and makes a response request with “M · a” as the request source ID. Relay transmission of signal (s1702). Terminals existing in an area where the short-distance wireless communication of the child terminal a is possible are the parent terminal M and the child terminal d. In the parent terminal M, the response request signal (s1702) transmitted from the child terminal a is ignored. (If received, it is discarded.)
The response request signal (s1702) transmitted from the child terminal a is received by the child terminal d, and in the child terminal d, a response signal (s1703) including “M · a” as the request source ID and “d” as the response source ID. ). Further, the child terminal d adds the short-range wireless ID “d” of its own terminal to the request source ID of the response request signal received from the child terminal a, and uses “M · a · d” as the request source ID. The response request signal (s1704) is relayed and transmitted.

  The response request signal (s1704) transmitted by the child terminal d is received by the child terminal a, but the child terminal a has already returned a response signal (s1701) to the response request signal (s1700) from the parent terminal M. Therefore, the response request signal (s1704) received from the child terminal d is ignored.

  The response request signal relayed by the child terminal a and the child terminal d does not perform any further operation.

  The response signal (s1703) returned from the child terminal d is received by the child terminal a. The child terminal “a” relays and transmits this response signal (s 1703) since the short-distance wireless ID of its own terminal is included in the request source ID of the response signal (s 1703). The response signal (s1703) relay-transmitted from the child terminal a is received by the parent terminal M.

  Based on the response source ID of the response signal (s1701) received from the child terminal a and the response signal (s1703) received by relaying the child terminal a from the child terminal d, the parent terminal M is in the vicinity of the parent terminal M. It can be identified that the child terminal d exists within the distance wireless communication range and the child terminal d exists within the short-range wireless communication range of the child terminal a.

  Similarly, the response request signal (s1710) transmitted from the parent terminal M is received by the child terminal b, the response request signal (s1712) relayed by the child terminal b is received by the child terminal e, and the child terminal e relays. The transmitted response request signal is received as a response request signal (s1714) at the child terminal g, and is received as a response request signal (s1717) at the child terminal h.

  Similarly, the response request signal (s1720) transmitted by the parent terminal M is received by the child terminal c, and the response request signal (s1722) relayed by the child terminal c is received by the child terminal f.

  Then, the parent terminal M can identify the positional relationship of each child terminal from the response signals (s1711, s1713, s1715, s1718, s1721, s1723) from each child terminal with respect to the response request signal. The positional relationship between the identified child terminals is stored as shown in FIG. Further, the parent terminal M knows that it has not received a response signal from the child terminal i.

  These signal processes will be described later. It is executed by the monitored application operation of the child terminal. At that time, the signal identification processing is performed by the signal processing unit included in the short-range wireless communication unit 840 of FIG.

  The operation of the third embodiment of the present invention in which the lead terminal holding the operation as described above is held by the lead person and the lead terminal is held by the lead person will be described with reference to FIGS.

  FIG. 18 is a flowchart for explaining the operation of the monitored application program performed in the child terminals 801 (1) to 801 (n) in the present embodiment. The main part of this operation is the same as that described in the above-mentioned operation of short-range wireless communication.

  The position monitoring operation of the child terminals 801 (1) to 801 (n) performed by the parent terminal 801 (0) will be described later with reference to FIG. 19, but the parent terminal 801 (0) periodically requests the response request described above. A signal is transmitted to the surroundings, and a response signal returned from each of the child terminals 801 (1) to 801 (n) existing within the reception range of the response request signal including the response request signal relayed by the child terminal is received. Thus, the positions of the child terminals 801 (1) to 801 (n) constituting the mobile terminal group 800 are grasped.

  In each of the child terminals 801 (1) to 801 (n), the monitored application program operates during the action. This activation is premised on an operation by the lead person holding each of the child terminals 801 (1) to 801 (n). However, a timer start based on a preset time may be used, or a parent held by the lead person may be separately provided. It may be activated by remote operation from the terminal 801 (0).

  Each of the child terminals 801 (1) to 801 (n) constantly monitors reception of signals by short-range wireless communication (s1802). If no signal is received within a predetermined time (s1811: YES), it means that there is no other terminal that accompanies the terminal, and the mobile terminal group 800 has been left. Since it is in the state, alarm B is generated at the terminal (s1812). The setting of the specified time assumes a state in which a response request signal cannot be received continuously several times, for example, in a position monitoring operation that is regularly performed by the parent terminal 801 (0). Further, the position monitoring operation periodically performed by the parent terminal 801 (0) assumes a time interval of about 5 minutes or 10 minutes. Alarm B warns that the terminal has left the group.

  When a short-range wireless communication signal is received (s1802: YES), it is identified whether the signal is a response request signal or a response signal (s1803).

  If it is a response request signal, it is confirmed whether or not the response signal has been returned in the same cycle (s1804). If the response request signal is received after returning the response signal (s1804: YES), the received response request signal is discarded (s1805) and ignored. In other words, the response request signal is slightly shifted in time when the short-range wireless communication area overlaps with a large number of terminals due to the relay transmission of other terminals that have received the response signal and returned the response signal. Therefore, it will be received from a large number of terminals. Since the response signal need only be returned once in the same period, only the response process for the response request signal received first is executed.

  Therefore, if the response signal has not been returned yet (s1804: NO), the above-described response signal return processing (s1806) and response signal relay processing (s1807) are executed.

  On the other hand, if the received short-range wireless communication signal is a response signal, it is confirmed whether or not it is a response signal to the response request signal relayed by the terminal itself (s1808). That is, it is identified by whether or not the short-range wireless ID of the terminal itself is included in the request source ID of the received response signal.

  If the short-range wireless ID of the terminal itself is not included (s1808: NO), the response signal is discarded (s1809) and ignored. If the short-range wireless ID of the own terminal is included (s1808: YES), the response signal is relayed and transmitted as it is (s1810).

  Each of the child terminals 801 (1) to 801 (n) repeats the above operation until the monitored application program ends.

  The operation of the third embodiment of the parent terminal 801 (0) that monitors the positions of the child terminals (1) to 801 (n) in this way will be described with reference to FIG.

  FIG. 19 is a flowchart for explaining the operation of the monitoring application program performed in the parent terminal 801 (0) in the present embodiment.

  This activation is premised on an operation by the lead person holding the parent terminal 801 (0), but may be a timer activation based on a preset time.

  When the monitoring application program is activated (s1900) and the monitoring cycle is reached (s1901: YES), the parent terminal 801 (0) measures the position of the own terminal by the GPS satellites 201 to 203. The positioning position information is stored in the memory 860 in time series as positioning data as shown in FIG. 15B (s1902). At this time, the operation of the scheduled position report to the monitoring device 701 is also included, but this scheduled position report uses 1 hour to 2 hours as a report interval, and the positioning data accumulated in the memory 860 so far is used for the scheduled position report. It transmits to the monitoring apparatus 701 collectively.

  Subsequently, the above-described response request signal is transmitted by short-range wireless communication, and the operation of confirming the position of each of the child terminals 801 (1) to 801 (n) is performed (s1903).

  Until a response signal is received from all the child terminals 801 (1) to 801 (n) after the response request signal is transmitted, a slight time is counted by a timer (s1904), and the response signal is received after the lapse of the time. The operation is continued as if (s1905).

  As described with reference to FIGS. 16 and 17, the positional relationship between the child terminals 801 (1) to 801 (n) is grasped based on the response signals received from the child terminals 801 (1) to 801 (n). Then, as shown in FIG. 15C, it is stored in the memory 860 as positional relationship information (s1906).

  Subsequently, the presence / absence of a child terminal that does not return a response signal is confirmed from the positional relationship information (s1907). As a result, when it is confirmed that there is a child terminal that does not return a response signal (s1907: NO), the child terminal information is specified and a positioning request is made to the monitoring device 701 (s1908). Then, the alarm A is issued at the terminal (s1909). This alarm A displays that there is a child terminal that has left the group and information of the holder of the child terminal (name, phone number of the child terminal).

  Therefore, the lead person who is the holder of the parent terminal 801 (0) can specify the holder of the child terminal that has left the group due to the occurrence of the alarm A. Further, by separately receiving from the monitoring device 701 a response to the request for positioning of the child terminal requested to the monitoring device 701, the current position of the child terminal that has left can be specified. Based on such information, the lead person can easily search for the holder of the child terminal that has left, and can deal with it before it becomes important. For example, by calling the child terminal and instructing to return to the group by teaching the positional relationship between the child terminal and the group, the sub-leader may pick up the holder of the child terminal that has left it can.

  Next, the third embodiment of the present invention using the parent terminal 801 (0), the child terminals 801 (1) to 801 (n), the monitoring device 701, and the standby terminal 501 on the school side described above. The overall operation will be described with reference to FIG.

  FIG. 20 is a sequence diagram showing the mutually related operations of the parent terminal 801 (0), the child terminals 801 (1) to 801 (n), the monitoring device 701, and the terminal 501 in the present embodiment.

  FIG. 20A is a sequence diagram for explaining an operation based on a scheduled report of positioning results executed by the parent terminal 801 (0) described in correspondence with step s1902 of FIG.

  The parent terminal 801 (0) transmits the positioning data that has been stored in the memory 860 until then to the monitoring device 701 by the scheduled position report (s2000). The monitoring apparatus 701 performs route display processing of the positioning data transmitted from the parent terminal 801 (0), and plots the route on which the parent terminal 801 (0) has moved on the map (s2001). The map information subjected to the route display processing is notified to the terminal 501 (s2002). For example, if the monitoring device 701 and the terminal 501 are not connected, an e-mail attached with this map information is periodically sent to the terminal 501. Further, when the terminal 501 is connected to the monitoring device 701 and displays a specific route display screen on the WEB, this map information is periodically updated and displayed. In this way, the terminal 501 can confirm the periodic position and movement route of the group on the map.

  FIG. 20B is a sequence diagram illustrating the operation when the parent terminal 801 (0) specifies the child terminal information and issues a positioning request to the monitoring apparatus 701, which is described in correspondence with step s1908 in FIG. It is.

  When the parent terminal 801 (0) confirms the existence of a child terminal that has left the group during the position monitoring operation of the child terminals 801 (1) to 801 (n), the positioning automatically identifies the child terminal. A request can be sent to the monitoring device 701. The parent terminal 801 (0) can arbitrarily specify a child terminal and make a positioning request to the monitoring apparatus 701.

  When the parent terminal 801 (0) specifies the child terminal information (for example, telephone number information) and makes a positioning request to the monitoring device 701 (s2010), the monitoring device 701 determines the child terminal from the specified child terminal information. The terminal ID of the device is identified, and the positioning instruction is transmitted by designating the terminal ID (s2011). The child terminal that has received the positioning instruction performs GPS positioning using the GPS satellites 201 to 203 and reports the positioning result to the monitoring device 701 (s2012). Receiving the positioning result report from the child terminal, the monitoring device 701 performs processing for plotting the positioning data on the map, and transmits the positioning result information to the parent terminal 801 (0) (s2013). The parent terminal 801 (0) can know the position information of the requested child terminal by displaying the positioning result information (s2014).

  FIG. 20C is a sequence diagram for explaining the operation of processing executed when the standby-side terminal 501 wants to arbitrarily confirm the position of the group.

  For example, when a school official who has sent out a school trip uses the terminal 501 on the standby side, the position information of all members of the school trip group at that time can be grasped.

  The terminal 501 connects to the monitoring apparatus 701, and makes a positioning request for confirming the position of the group using a specific menu on the WEB (s2020). The monitoring apparatus 701 reads all mobile terminal information corresponding to the group ID shown in FIG. 14, designates the terminal ID, and transmits a positioning instruction (s2021). The parent terminal 801 (0) and the child terminals 801 (1) to 801 (n) that have received the positioning instruction perform GPS positioning using the GPS satellites 201 to 203 and report the positioning result to the monitoring device 701. (S2022, s2023). Upon receiving the positioning result reports from the parent terminal 801 (0) and the child terminals 801 (1) to 801 (n), the monitoring device 701 performs processing for plotting the positioning data on a map, and displays the positioning result information on the terminal It is transmitted to 501 (s2024). The terminal 501 can know the positional information of all the requested groups by displaying the positioning result information (s2025).

  As described above, according to the third embodiment of the present invention, the positional relationship by the short-range wireless communication between the parent terminal 801 (0) and the child terminals 801 (1) to 801 (n). Therefore, even if a large number of people are acting like a school excursion group, the child terminal that has left the group is connected to the parent terminal 801 (0) held by the leader. The existence of the student to be held is displayed immediately, and actions for ensuring the safety of the child's actions can be taken quickly. On the other hand, even when a school official who sent out a school excursion group waits at school, it is possible to grasp the behavior of the group one by one, so it has a remarkable effect on the management of the behavior schedule and the prediction and handling of abnormal behavior Play.
