  FIG. 7 is a block diagram illustrating a configuration example of the mobile phone 2 of FIG. The control unit 71 controls each unit via the input / output bus 73 and controls the overall operation of the mobile phone 2. The communication unit 72 communicates with various devices via the communication network 13 and outputs received packets to the control unit 71. The memory 74 is composed of a non-volatile flash memory, stores information such as a registered telephone number, and notifies, for example, that the monitoring target person who has been transmitted from the center device 11 has entered the danger area. E-mails containing messages to be stored are stored. The LCD 75 displays various information based on instructions from the control unit 71. For example, the LCD 75 displays a message for notifying the monitoring person that the monitoring target person has entered the danger area. The input unit 76 includes a numeric keypad, a cross key, and the like, and receives input from a user (monitor) of the mobile phone 2. The speaker 77 and the microphone 78 operate when the control unit 71 is executing the call mode, and the speaker 77 receives the voice transmitted from another telephone or the like from the control unit 71 via the input / output bus 73. The microphone 78 collects the speech of the user of the mobile phone 2 and outputs it to the control unit 71 via the input / output bus 73.

  The configuration of the PHS terminal 4 is basically the same as the configuration of the mobile phone 2.

  Next, the operation of the monitoring system in FIG. 4 will be described. First, the setting process of the personal computer 1 for setting a dangerous area will be described with reference to the flowchart of FIG.

  In step S <b> 11, the control unit 61 accesses the center device 11 when the monitor 64 operates the keyboard 64 or the like and is instructed to set a dangerous area, and inputs the ID of the monitoring target person input by the monitor. Send. That is, prior to using this monitoring system, the monitor needs to register information regarding the monitoring target person in the center apparatus 11. The center device 11 stores the danger area set by the supervisor (personal computer 1) in association with the issued ID.

  In step S12, the control unit 61 displays the menu page transmitted from the center apparatus 11 on the position information display unit 31 including a CRT.

  FIG. 9 is a diagram illustrating an example of the menu page displayed in step S12. As shown in the figure, for example, a button 91 that is operated when setting attribute information (dangerous area) for the first time and a button 92 that is operated when changing the setting of already set attribute information are displayed. , Move the cursor 93 to select.

  In step S13, the control unit 61 determines whether or not initial setting of attribute information is selected (the button 91 is selected in FIG. 9), and determines that initial setting of attribute information is selected. If YES in step S14, the flow advances to step S14 to execute attribute information setting processing. If the control unit 61 determines in step S13 that setting attribute information has not been selected, that is, a change in setting has been selected (button 92 in FIG. 9 has been selected), step S15. Then, the attribute information setting change process is executed. And a process is complete | finished after the process of step S14 or step S15.

  Next, detailed processing of the attribute information setting processing of the personal computer 1 executed in step S14 of FIG. 8 will be described with reference to the flowchart of FIG.

  In step S <b> 31, the control unit 61 accesses the attribute information setting page stored in the center device 11 and displays the map information of the area selected by the monitor on the position information display unit 31.

  FIG. 11 is a diagram illustrating an example of the map information displayed in step S31. For example, as shown in the figure, a map is displayed, and the supervisor can set the dangerous area E by operating the cursor 93 with the mouse 65 and dragging. Further, the danger area E may be set by clicking by the supervisor for each predetermined section.

  In step S32, the control unit 61 determines whether or not a dangerous area has been input from the supervisor. As described above, the control unit 61 returns to step S31 until it is determined that the dangerous area has been input by dragging or the like. Repeat the process. If the control unit 61 determines that the dangerous area has been input, the control unit 61 proceeds to step S33 and instructs the monitoring device 11 to set the input area as the dangerous area. The input information regarding the dangerous area is transmitted from the communication unit 33 to the center device 11 via the communication network 13 together with the ID.

  In step S34, the control unit 61 determines whether or not it is instructed to end the setting of the attribute information (dangerous area). If it is determined that the instruction is not instructed, the control unit 61 returns to step S31 and performs the subsequent processing. Run repeatedly. On the other hand, when it is determined in step S34 that the setting is instructed, the control unit 61 executes the processes after step S14 in FIG.

  In the above, the process executed in step S14 of FIG. 8 has been described, but also in step S15, a dangerous area is set by the same process as in FIG. That is, in the center apparatus 11, map information corresponding to the transmitted ID and having already set a dangerous area is read and displayed on the position information display unit 31 of the personal computer 1. The monitor operates the mouse 65 or the like on the displayed map information to set a dangerous area and transmits it to the center device 11. In the center device 11, the update is registered with the changed danger area. Thus, the supervisor can easily set the dangerous area. Alternatively, the center device 11 may be accessed from the mobile phone 2 and the dangerous area may be set by the processing as described above.

  Next, the attribute information (dangerous area) registration process of the center apparatus 11 will be described with reference to the flowchart of FIG.

  In step S41, the center control device 21 determines whether or not an ID has been transmitted from the personal computer 1, and waits until it is determined that the ID has been transmitted. If the center control device 21 determines that the ID has been transmitted, the center control device 21 proceeds to step S42 and transmits a menu page. The menu page is transmitted to the personal computer 1 via the communication network 13, and the screen shown in FIG. 9 is displayed on the position information display unit 31 of the personal computer 1.

  Then, in step S43, the center control device 21 sets the setting information (map) registered in the storage device 42 in association with the ID in response to the selection of new dangerous area registration or risk area setting change. Information) is read out and transmitted from the center communication device 22. The map information is transmitted to the personal computer 1 via the communication network 13. Thereby, in the personal computer 1, for example, the map information as shown in FIG. 11 is displayed, and the supervisor can set the dangerous area.

  In step S44, the center control device 21 determines whether or not the setting of the dangerous area has been instructed, and waits until instructed. If the center control device 21 determines that the setting has been instructed, the center control device 21 proceeds to step S45, sets a dangerous area, and registers it in the storage device 42 in association with the ID. Thus, in the case of new registration, the designated area is registered as a dangerous area, and in the case of setting change, the dangerous area is updated and registered with the designated area.

  In step S46, the center control device 21 determines whether or not the setting has been completed in the personal computer 1, returns to step S44 until the setting is completed, and repeats the subsequent processing. On the other hand, in the personal computer 1, when the setting of the attribute information is finished, the process is finished.

  In this monitoring system, the monitor can change the security mode by accessing a predetermined page of the center device 11 from the mobile phone 2. For example, assume that the security mode is on when monitoring the position of the person being monitored, and the security mode is off when not monitoring. Next, processing of the mobile phone 2 that changes the security mode will be described with reference to the flowchart of FIG.

  In step S71, when the supervisor operates the input unit 76 and instructs to change the security mode, the control unit 71 accesses a predetermined page stored in the center device 11 accordingly.

  In step S <b> 72, the control unit 71 controls the communication unit 72 to transmit the ID of the monitoring target person input from the input unit 76 by the monitoring person to the center device 11. The center apparatus 11 that has received the ID confirms the current mode state based on the ID of the person to be monitored, and transmits a page for the monitor to select the setting to the mobile phone 2.

  In step S <b> 73, the control unit 71 that has received the setting page transmitted from the center device 11 displays the security mode setting page on the LCD 75.

  FIG. 14 is a diagram illustrating an example of a setting page displayed on the LCD 75. As shown in the figure, for example, the supervisor can turn on the security mode by operating the first button of the numeric keypad constituting the input unit 76 and turn it off by operating the second button.

  In the setting page as shown in FIG. 14, when the security mode is input from the supervisor, the control unit 71 transmits the input security mode to the center apparatus 11 in step S74. Through the processing as described above, the supervisor can easily change the security mode. Naturally, the monitor can access the center apparatus 11 from the personal computer 1 and change the security mode, as described above.

  Next, a series of processing of the monitoring system of FIG. 4 will be described with reference to the flowcharts of FIGS. 15 to 17 and FIG. First, the position detection process of the position detection device 12 will be described with reference to the flowchart of FIG.

  In step S <b> 81, the position detection device 12 detects the current position of the monitoring target person based on the position information of the receiving terminal receiving the radio wave output from the PHS terminal 4. That is, receiving terminals that receive radio waves from the PHS terminal 4 are installed at various positions, and the plurality of receiving terminals are connected to the position detection device 12 by wire. In step S <b> 82, the position detection device 12 transmits the detected position information of the monitoring subject to the center device 11 via the communication network 13.

  Next, the monitoring process of the center apparatus 11 will be described with reference to the flowchart of FIG.

  In step S91, the center control device 21 determines whether or not the position information transmitted from the position detection device 12 is information related to a monitoring target person whose security mode is on. The center control apparatus 21 waits until it is determined that the information is related to the monitoring target person whose security mode is on. If the center control apparatus 21 determines that the information is related to the monitoring target person whose security mode is on, the process proceeds to step S92. Is received (captured).

  In step S93, the center control device 21 reads the registered setting information (map information in which the dangerous area is set). In step S94, the center control device 21 matches the notified current position information of the monitoring target person with the map information in which the dangerous area is set.

  In step S95, the center control apparatus 21 determines whether or not the monitoring target person exists in the dangerous area as a result of the matching executed in step S94. If the center control apparatus 21 determines that the monitoring target person does not exist in the dangerous area, the center control apparatus 21 returns to step S91. The subsequent processing is repeatedly executed. On the other hand, if it is determined in step S95 that the monitoring target person is present in the dangerous area, the center control device 21 enters the warning mode, and in step S96, the PHS terminal 4 possessed by the monitoring target person enters the dangerous area. Send warning information to notify you.

  Further, in step S97, the center control device 21 reads the telephone number or mail address of the monitor's mobile phone 2 registered in advance as a notification destination from the storage device 42, and the monitoring target person enters the danger area. Is sent to the mobile phone 2 via the communication network 13.

  Further, in step S98, the center control device 21 notifies the personal computer 1 possessed by the monitor via the communication network 13 of warning information for notifying that the monitoring target person has entered the danger area. . When a plurality of notification destinations to be notified in step S97 and step S98 are registered, the center control device 21 notifies all the notification destinations that the monitoring target person exists in the dangerous area.

  In step S99, the center control device 21 determines whether or not the cancellation of the warning mode is instructed from the personal computer 1 or the cellular phone 2, and returns to step S96 until it is determined that the cancellation is instructed. The subsequent processing is repeatedly executed. That is, warning information is transmitted to the PHS terminal 4, the mobile phone 2, and the personal computer 1 every predetermined time until the warning mode is canceled.

  If the center control device 21 determines in step S99 that the personal computer 1 or the mobile phone 2 has instructed to cancel the warning mode, the center control device 21 proceeds to step S100 and cancels the warning mode. For example, when the monitoring person confirms the safety of the monitoring target person based on the notified position information of the monitoring target person, the mobile phone 2 instructs the center device 11 to cancel the warning mode.

  Next, warning output processing of the PHS terminal 4 will be described with reference to the flowchart of FIG. In step S111, the control unit of the PHS terminal 4 determines whether warning information has been transmitted from the center apparatus 11, and waits until it is determined that it has been transmitted. If the control unit determines that the warning information has been transmitted, the control unit proceeds to step S112 and displays it.

  FIG. 18 is a diagram illustrating an example of warning information displayed on the PHS terminal 4 owned by the person to be monitored. As shown in the figure, for example, when the monitoring subject is a child, a message such as “I am about to leave the area of action determined by the school. Please return immediately” is displayed. Further, when the monitoring subject is an elderly person, for example, a message such as “Do not enter from here” is displayed. The person to be monitored who has confirmed such a message confirms that he / she is in the dangerous area and leaves the dangerous area.

  Then, the process returns to step S111, and for example, warning information is repeatedly displayed at predetermined intervals until the warning mode is canceled in the center apparatus 11.

  Next, warning information output processing of the mobile phone 2 will be described with reference to the flowchart of FIG.

  The processes of steps S121 and S122 are the same as the processes of the PHS terminal 4 described with reference to the flowchart of FIG. 17 (the processes of steps S111 and S112). That is, in step S121, the control unit 71 determines whether warning information has been transmitted from the center apparatus 11, and waits until it is determined that it has been transmitted. If the control unit 71 determines that the warning information has been transmitted from the center device 11, the control unit 71 proceeds to step S 122 and displays it on the LCD 75.

  FIG. 20 is a diagram illustrating an example of warning information displayed on the mobile phone 2. As shown in the figure, when the monitoring subject is a child, for example, a message such as “Ichiro is going out of the action area. Please deal with it” is displayed. Further, since the position of the monitoring target person is also displayed, the monitoring person who has confirmed this message goes to check the place where the monitoring target person is located even when he / she is out, or the PHS terminal 4 possessed by the monitoring target person. You can take measures such as calling.

  When confirming the safety of the monitoring target person, the monitoring person instructs the center apparatus 11 to cancel the warning mode. In step S123, the control unit 71 determines whether or not canceling the warning mode is input from the input unit 76. The control unit 71 returns to step S122 until it is determined that the cancellation of the warning mode has been input, and continues to display the warning information.

  On the other hand, in step S123, if the control unit 71 determines that the monitoring person has confirmed that the monitoring target person is safe and has input from the input unit 76 to cancel the warning mode, the control unit 71 proceeds to step S124 and displays warning information. Is deleted, and the center apparatus 11 is instructed to cancel the warning mode.

  In the above, the warning information output process of the mobile phone 2 has been described with reference to the flowchart of FIG. 19, but the same process is executed in the personal computer 1 to display the warning information. For example, warning information as shown in FIG. 21 is displayed on the position information display unit 31 of the personal computer 1.

  In FIG. 21, a map of an area around a point where the monitoring target person is present is displayed in the approximate center of the position information display unit 31, and the position of the monitoring target person is designated by the position display pointer 101. Also, below the map, a message such as “Ichiro is in the danger area. Please take action” is displayed.

  In the above, although the terminal which the monitoring subject has is a PHS terminal, any terminal may be used as long as the position can be detected. For example, when the person to be monitored has a mobile phone, the position can be specified by the principle of so-called triangulation. Further, even when the monitoring subject has a GPS terminal, the position detection device 12 can receive the position information transmitted from the GPS terminal and specify the position.
