In step S34, the control section 61
It is determined whether or not it is instructed to end the setting of the attribute information (dangerous area). If it is determined that the instruction has not been instructed, the process returns to step S31, and the subsequent processes are repeatedly executed. On the other hand, when it is determined in step S34 that an instruction to end the setting has been issued, the control unit 61 executes the processing of step S14 and subsequent steps in FIG.

The processing executed in step S14 of FIG. 8 has been described above.
Also in 15, the danger area is set by the same processing as in FIG. That is, in the center device 11, the map information corresponding to the transmitted ID and in which the dangerous area is already set is read out, and displayed on the position information display section 31 of the personal computer 1. The monitor operates the mouse 65 or the like on the displayed map information to set a danger area, and transmits the danger area to the center apparatus 11. In the center device 11, the information is updated and registered according to the changed dangerous area. In this way, the observer can easily set the danger area. Alternatively, the center device 11 may be accessed from the mobile phone 2 and a dangerous area may be set by the above-described processing.

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

In step S41, the center control device 21 determines whether or not the 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 process proceeds to step S42, and transmits the 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 section 31 of the personal computer 1.

In step S43, the center controller 21 sets the registration registered in the storage device 42 in association with the ID in response to selection of new registration of a dangerous area or change of setting of a dangerous area. Information (map 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. As a result, in the personal computer 1, for example, map information as shown in FIG. 11 is displayed, and the observer can set a 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 the instruction is given. If the center control device 21 determines that the setting has been instructed, the process proceeds to step S
In step 45, a dangerous area is set, and registered 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 by the designated area.

In step S46, the center control device 21 determines in the personal computer 1 whether or not the setting has been completed.
4 and the subsequent processes are repeatedly executed. on the other hand,
When the setting of the attribute information is completed in the personal computer 1, the processing is completed.

In this monitoring system, the observer
Change the security mode from the mobile phone 2 to the center device 11
Can be changed by accessing a predetermined page.
For example, assume that the security mode is on when monitoring the position of the person to be monitored, and that the security mode is off when not monitoring. Next, FIG.
The process of the mobile phone 2 for changing the security mode will be described with reference to the flowchart of FIG.

In step S71, the control section 71
When the observer operates the input unit 76 and instructs to change the security mode, a predetermined page stored in the center device 11 is accessed accordingly.

The control section 71 determines in step S72

Next, a series of processes 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 S81, the position detecting device 1
2 detects the current position of the monitoring target 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 the radio waves of the PHS terminal 4 are installed at various positions, and the plurality of receiving terminals are connected to the position detecting device 12 by wire.
Then, in step S82, the position detecting device 12
Transmits the detected position information of the monitoring target person to the center device 11 via the communication network 13.

Next, the monitoring process of the center device 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 relating to a monitoring target whose security mode is on. Center control device 21
Waits until it is determined that the information is related to the monitored person whose security mode is on. If it is determined that the information is related to the monitored person whose security mode is on, the process proceeds to step S92 and receives the information ( take in).

In step S93, the center control device 21 reads the registered setting information (map information in which a dangerous area is set). Then, 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 device 21 obtains the result of the matching executed in step S94,
It is determined whether or not the monitoring target exists in the dangerous area. If it is determined that the monitoring target does not exist in the dangerous area, step S91 is performed.
And the subsequent processing is repeatedly executed. On the other hand, when the center control device 21 determines in step S95 that the monitored person is in the dangerous area, the center control device 21 enters the warning mode. In step S96, the PHS terminal 4 of the monitored person enters the dangerous area. Send warning information to notify that

The center control device 21 determines in step S
At 97, the telephone number and the mail address of the mobile phone 2 of the observer registered in advance as the notification destination are read from the storage device 42, and the warning information for notifying that the monitored person has entered the dangerous area, The data is transmitted to the mobile phone 2 via the communication network 13.

Further, in step S98, the center control device 21 sends, via the communication network 13, warning information to the personal computer 1 of the monitor to notify that the monitor target has entered the dangerous area. To notify. 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 has been instructed from the personal computer 1 or the mobile phone 2, and continues until the center controller 21 determines that the cancellation has been instructed. Returning to S96, the subsequent processing is repeatedly executed. That is, the warning information is transmitted to the PHS terminal 4, the mobile phone 2, and the personal computer 1 at predetermined time intervals until the warning mode is released.

If the center control device 21 determines in step S99 that the personal computer 1 or the mobile phone 2 has instructed to release the warning mode, the process advances to step S100 to release the warning mode. For example, when the observer confirms the safety of the monitored person based on the notified position information of the monitored person, the mobile phone 2 instructs the center device 11 to release the warning mode.

Next, the warning output process 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 or not warning information has been transmitted from the center device 11, and waits until it is determined that warning information has been transmitted. And
When the control unit determines that the warning information has been transmitted,
Proceed to step S112 to display it.

FIG. 18 shows the PHS terminal 4 of the person to be monitored.
FIG. 5 is a diagram showing an example of warning information displayed on a screen. As shown in the figure, for example, when the monitoring target is a child, a message such as "I am about to leave the action area determined by the school. Please return immediately" is displayed. If the monitoring target is an elderly person, the message is, for example, "Do not enter from here." The monitoring subject who confirms such a message confirms that he / she is in the dangerous area, and leaves the dangerous area.

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

Next, with reference to the flowchart of FIG. 19, a process of outputting the warning information of the mobile phone 2 will be described.

The processing of steps S121 and S122 is the same as the processing of the PHS terminal 4 (the processing of steps S111 and S112) described with reference to the flowchart of FIG. That is, step S121
In, the control unit 71 determines whether or not the warning information has been transmitted from the center device 11, and waits until it is determined that the warning information has been transmitted. When determining that the warning information has been transmitted from the center device 11, the control unit 71 proceeds to step S122 and displays it on the LCD 75.

FIG. 20 is a diagram showing an example of warning information displayed on the mobile phone 2. As shown in FIG. As shown in the figure, when the monitoring target is a child, a message such as "Ichiro is going out of the action area. Please take action" is displayed. In addition, since the position of the monitoring target is also displayed, the monitoring target who confirms this message can go to the place where the monitoring target is located, even if the user is out, or use the PHS terminal 4 of the monitoring target. You can take countermeasures such as calling.

When the safety of the monitored person is confirmed, the monitored person instructs the center device 11 to cancel the warning mode. Then, in step S123, the control unit 71 determines whether or not cancellation of the warning mode has been input from the input unit 76. The control unit 71 proceeds to step S12 until it determines that cancellation of the warning mode has been input.
Return to step 2 and continue to display the warning information.

On the other hand, in step S123, the control unit 71 checks the safety of the
If it is determined that the warning mode has been released from step 6, the process proceeds to step S124, where the display of the warning information is erased, and the center apparatus 11 is instructed to release the warning mode.

In the above, the output processing of the warning information of the portable telephone 2 has been described with reference to the flowchart of FIG. 19, but the same processing is executed also in the personal computer 1, and the warning information is displayed. And
The position information display section 31 of the personal computer 1 includes:
For example, warning information as shown in FIG. 21 is displayed.

In FIG. 21, a map of the area around the point where the monitoring target is located is displayed substantially at the center of the position information display section 31, and the position of the monitoring target is indicated by the position display pointer 1.
It is specified by 01. Also, at the bottom of the map, "Ichiro is in a danger area. Please take action."
Is displayed.

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

[0077]

As described above, according to the present invention, the observer can easily and surely confirm that the monitored person has entered the dangerous area. Further, since it is not necessary to constantly monitor the moving monitoring target person, the labor of the monitoring person can be reduced.
