Next, the operation of this embodiment shown in FIGS. 1 and 2 will be described in detail.

First, the resident 10 who uses the automatic security system of this embodiment registers the position (longitude) of the base point 30 such as his home in the base point position management table 82 of the position information management station 80 in advance. The ID of the mobile terminal 20 carried and carried by the resident 10 (in this embodiment, the telephone number of the mobile terminal 20) is registered in the current position information calculation unit 81 of the position information management station 80, and the mobile terminal 20's If the current position information and the position of the base point 30 are far apart,
Positional information is used as data for determining whether the resident 10 carrying the mobile terminal 20 determines that the base point 30 is absent (in the present embodiment, distance data is set in units of kilometers, and is set as distance). It is registered in the absence / at-home reference data 83 of the management station 80.

When the resident 10 is at home at the base point 30, the security terminal device 40 installed at the base point 30 is in the non-security mode.

Here, it is assumed that the resident 10 goes out carrying the mobile terminal 20. When the mobile terminal 20 enters the communication area of any one of the base stations 50, the mobile terminal 20 performs a positioning request operation, and the positioning request by the positioning request operation sends the position information via the base station 50 and the mobile communication network 60. It is transmitted to the management station 80. Upon receiving the positioning request and the ID (telephone number) of the mobile terminal 20 attached to the positioning request, the location information management station 80 causes the current location information calculation unit 81 to provide the current location information (longitude) of the mobile terminal 20. To calculate. The calculation method of the current position information is any one of the methods described in FIGS. 3, 4, and 5.

The current position information calculated by the current position information calculation unit 81 is sent to the absence / at-home determination unit 84, and the absence / at-home determination unit 84 presents the current position information (longitude) and the base position management table (longitude). Distance to 82 (distance)
To calculate. And absence / at-home standard data (distance)
83 is compared with the distance, and if the distance <distance, it is determined that the resident 10 carrying the mobile terminal 20 is not at the base point 30, and if the distance ≧ distance, the resident 10 is at home at the base point 30. Or, it is out, but the base point is 30
It is determined that it is ready to return to the base point 30 immediately after going out to the vicinity of.

When the determination by the absence / at-home determination unit 84 indicates that the user is at home or out of the vicinity, the position information management station 8
0 does nothing and waits for the next positioning request.

When the determination by the absence / at-home determination unit 84 indicates absence, the absence / at-home determination unit 84 sets the base point 30.
The security mode setting signal for the security terminal device 40 is transmitted via the general public network 70.

When the security terminal device 40 receives the security mode setting signal from the absence / at-home determination unit 84 of the position information management station 80, the control unit 44 causes the security terminal device 40 to operate.
After confirming that is the non-security mode, the security terminal device 40 is set to the security mode.

The security terminal device 40 in the security mode monitors the output information of each sensor 41 and also monitors the state of each appliance 42 to detect the presence or absence of an abnormality. Then, when an abnormality such as forgetting to close the power supply or the main plug is detected from the state of each appliance 42, a control signal for closing the main plug or disconnecting the power source is output to the appliance 42, thereby Control is performed so that the abnormal state is resolved. The control result is confirmed by re-monitoring whether the abnormality has been resolved.

The security terminal device 40 in the security mode creates the above monitoring and control results as monitoring control status information, and sends the monitoring control status information to the transmission / reception unit 4
5 to the location information management station 80 via the general public network 70, and the location information management station 80 sends the status information of the monitoring control to the mobile terminal 20. The resident 10 carrying the mobile terminal 20 can confirm the result of the supervisory control by the security terminal device 40 at the base point 30 such as his / her home based on the supervisory control status information received by the mobile terminal 20.
