DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a first embodiment of the present invention will be described with reference to FIG.

A GPS signal from a GPS satellite 6 is received by a GPS antenna 1 built in a school bag (or a school bag) which is carried by a child or a student shown in FIG. 1 and sent to a GPS receiver 2. The GPS receiver 2 obtains its own position and current time using GPS signals, and sends these data to the communication controller 3. The communication controller 3 outputs to the mobile phone 4 a signal for controlling the formatting of the data to be transmitted to the central management station 5 and the transmission of the mobile phone 4 based on the input data. In addition to the above-mentioned self-position and current time, self-identification code and error correction coding can be added to the formatted transmission data. This transmission data is also output from the communication controller 3 to the mobile phone 4. The mobile phone network 7 installed on the ground is used for the communication path from the mobile phone 4 to the central management station 5. The mobile phone 4 transmits the transmission data to the central management station 5 in a burst manner (once per hour) in bursts under the control of the communication controller 3. The central management station 5 receives the transmission data from all the subscribers' school bags, and records and updates the data.

The home 8 of the kindergarten or student inquires the central management station 5 about the whereabouts of the kindergarten or student (that is, the location of the school bag) by telephone or e-mail (or may go directly to the central management station 5).

The central management station 5 notifies the home 8 of the latest whereabouts of children and students.

Note that the communication controller 3 also has a power-on / off control function for the GPS receiver 2 and the mobile phone 4 in order to reduce power consumption. It is possible to turn on the GPS receiver 2 and the mobile phone 4 in accordance with the data transmission, and turn off the power until the next transmission after the transmission is completed.

The communication controller 3 also has a communication protocol control function for transmitting data to the saturation management station 5.

Next, a second embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 2, a portable satellite communication terminal (such as a portable satellite telephone as planned in the Iridium Project) 204 is used instead of the portable telephone 4 of FIG. Further, a communication satellite 201 is used instead of the mobile phone network 7 of FIG.

Then, the central control station 5 also receives data from the communication satellite 201. In this embodiment, compared to the embodiment of FIG. 1, a satellite communication line is used instead of a mobile telephone network installed on the ground, and therefore the system of the present invention is expected to exert its effect most effectively. At the time of occurrence, the communication path from the school bag to the Central Management Bureau is excellent in survivability.

[0023]

As is apparent from the above description, according to the present invention, the following effects can be obtained.

The first effect is that the kindergarten children and elementary and junior high school students who have a school bag do not know their current position.
The home of children and elementary school children is to know the current location of children and elementary and junior high school students.

The reason is that the GPS built in the school bag
This is because the receiver can automatically determine the position with high accuracy (about 100 m) and notify the obtained position to the homes of children and elementary and junior high school students via the mobile phone network and the central management station.

The second effect is that the kindergarten children and elementary and junior high school students who carry the school bag do not have to do anything. (Even when it is difficult to keep calm in the event of a disaster such as an earthquake), your school bag can automatically notify you of your location at regular intervals.

The reason is that the communication controller incorporated in the school bag automatically transmits the position of the school bag and the current time to the central management station at regular intervals.
