BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile body position reporting device, and more particularly to a mobile body position reporting device using GPS reception and a public telephone line.

[0002]

2. Description of the Related Art GPS (Global Positioning System)
The satellite is originally a military satellite that covers the entire world of the United States, but by receiving GPS signals from several GPS satellites at the same time, it is possible to accurately know its own position on the earth. It has been used as a system to inform the driver of the current position of a car.

The original function of GPS is a positioning system using an orbiting satellite of the earth, and it is possible to specify an accurate position and time at that time. In the case of a navigation system for automobiles, for example, GPS reception becomes insufficient (because a GPS signal can be received from only one GPS satellite) while passing through a tunnel or a high-rise building street. For example, by combining the means for knowing the current position of the car using inertia and geomagnetism, and by adding map information to determine the exact self-position, display the self-position on the map on the display, and further route to the destination The function to search is added.

Conventionally, the current position of the self known in this way is mainly known by the self, and it is not important to inform other people. Therefore, in order to inform others of the current position of oneself, there is no choice but to use a mobile radio or a mobile phone and bother to make a voice (or data) contact.

In order to solve this problem, a moving object having a mobile radio is connected to each other by a method as shown in FIG.
An example described in Japanese Patent No. 67 has been proposed. In FIG.
A signal from the GPS satellite 30 is received by the GPS receiving unit 3 and the self-position information is stored in the data control unit 21.
When the T switch 31 is pressed and voice information is transmitted from the microphone 20 from the transmission unit 32, self-position information is automatically transmitted.

On the other hand, the position information (data) and the voice information are separated from the signal received by the receiving unit 33 by the separating unit 34, the voice information is output from the speaker 35, and the position information of the communication partner is decoded by the decoding unit 36. , Is displayed on the display unit 37.

An example described in Japanese Patent Laid-Open No. 223586/1988, which is shown in FIG. 3, has been proposed between moving bodies having mobile radio. In FIG. 3, the GPS signal is G
The PS receiving unit 3 receives and the self position is calculated by the calculating unit 5,
The self-position information (data) is stored in the storage unit 6. When the voice information is mainly transmitted / received by the voice unit 40, the transmission / reception unit 25, and the antenna 26, the self-position information can be exchanged with each other as necessary.

[0008]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the case of 6067 or Japanese Patent Laid-Open No. 63-223586, self-position information by GPS reception can be exchanged between mobile units having mobile radio, but there is a problem that a third party cannot access this position information. .

An object of the present invention is to provide a mobile unit position notification device which can freely access position information from a mobile unit from anywhere at any time.

[0010]

A mobile body position reporting device according to the present invention includes a current position information detecting means for receiving a signal from a GPS satellite and detecting its own current position as current position information, and the current position information. And position information transmitting means for reading out the current position information from the position information storing means, adding the individual identification number of itself, and transmitting it as position information with identification via a public telephone line. It is characterized by

DESCRIPTION OF THE PREFERRED EMBODIMENTS The operation of the present invention is as follows.
Position information from mobiles will be comprehensively managed through public telephone lines so that it can be accessed freely by third parties.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a mobile unit position notification device according to the present invention, and the same parts as those in FIGS. In addition, overlapping description is omitted.

In FIG. 1, GP from GPS satellite 30
The S signal is received by the GPS receiving unit 3 via the GPS antenna 1. At this time, since GPS reception imposes a heavy burden (power consumption) on a portable (moving) device, three types of reception methods can be selected: constant reception, scheduled reception by the timer 4, and reception only when necessary.

From the received GPS signal, the position and time control unit 5 calculates the position and the time at that position,
Write to memory 6 along with any other general information. This memory 6 always writes the latest information, and if the GPS signal cannot be received when necessary, the memory 6
It has a function to read and use the information written in and to store some information so that multiple pieces of information can be sent at one time.

The information read from the memory 6 is added with an individual serial number (for example, a telephone number may be used) for identifying itself by the serial number adding section 9, and the cellular phone antenna 2 is fed from the cellular phone transmitting section 10. To send. In this case as well, in order to save power consumption during transmission, three types of transmission methods can be selected: constant transmission, scheduled transmission by the timer 11, and transmission only when necessary.

When a call is required, the other party's call is received by the mobile phone receiving unit 7 via the mobile phone antenna 2, and the transmission / reception control unit 8 controls the GPS receiving unit 3 and the mobile phone transmitting unit 10.
Etc. are controlled to make a call.

In FIG. 2, a pedestrian 16 and a running car 1
7, current position information and the like from mobiles such as trains 18 are transmitted from the base station antenna 20 through the telephone station 12 to the management center 13
Are sorted (stored) based on the (individual identification) serial number (telephone number) of the mobile unit. Third party (eg, telephone subscriber 1
4 or the personal computer terminal 15) can freely access the current position of the mobile body and other information based on the serial number (telephone number) via the subscriber telephone line and the telephone station 12.

[0019]

As described above, according to the present invention, the information such as the current position of the mobile body can be freely accessed by a third party through the public telephone line (individual identification) based on the serial number (telephone number). There is.
