In FIG. 1, a position information transmitting device 100 is a device that constantly transmits position information of a position where the device itself is installed, a position information memory 10 for storing the position of the own device, and the storage contents of the position information memory 10. And a transmitter 30 for transmitting the generated position information from the antenna 40. As shown in [Table 1], the position information memory 10 stores an identification number (“123” in the case of [Table 1]) unique to each position information transmitting device 100 as information indicating the position of the own device. I have.

[Table 1]

On the other hand, the position information receiving terminal 200 is a terminal carried by the user, and receives the position information from the position information transmitting device 100 and displays the current position.
For this purpose, the position information receiving terminal 200

Similar to the position information transmitting device 101 of the third embodiment, the position information transmitting device 102 transmits an identification number and additional information as position information from the antenna 40. Here, the frequency of the radio wave emitted from the transmitter 30 is represented by fs for convenience. In the following description, a radio wave having a frequency fs is abbreviated as a radio wave fs, and a similar notation is used for a radio wave having a frequency other than fs. The transmission area of the radio wave fs emitted from the transmitter 30 by the position information transmitting device 102 may or may not overlap with the transmission area of another position information transmitting device (not shown). In addition, the position information transmitting device 102 transmits the radio wave fm transmitted from the position information host 300 (described later) to the receiver 35 via the antenna 41.
, The received data is processed by the received data processing device 25, and the data in the position information additional information memory 11 can be updated. Note that the data generation device 21 and the reception data processing device 25 can be integrated into one device. In addition, the transmitter 30 and the receiver 35 can be integrated into one transceiver, and the transmission antenna 40 and the reception antenna 41 can be shared.

On the other hand, the position information host 300 comprises a transmitting antenna 40, a transmitter 31 for transmitting a radio wave fm from the antenna 40, and an update information processing device 22 (details will be described later). Since the transmission area of the radio wave fm emitted from the transmitter 31 needs to cover all the position information transmitting devices including the position information transmitting device 102 and the position information transmitting device (not shown), the output radio wave intensity of the transmitter 31 is adjusted. Then, settings are made so as to satisfy this condition. The update information processing device 22 outputs the update information shown in [Table 5] to the transmitter 31. As shown in the table, the update information includes an identification number assigned to the position information transmitting device 102 for updating the additional information stored in the position information additional information memory 11,
The update information (update data in the table) of the additional information stored in the position information additional information memory 11 is included. The transmitter 31 transmits this update information from the antenna 40 using the radio wave fm.

[Table 5]

Next, the operation of the position information communication system according to the present embodiment will be described. When the position information host 300 needs to update the additional information related to the position of the position information transmitting device 102, the position information host 300 generates the update information by adding the identification number of the position information transmitting device 102 to the update data for the additional information. Is transmitted to the transmitter 31 and transmitted from the antenna 40 by radio waves fm. Location information transmitting device 102

The identification number included in the update information and the own identification number are collated, and if they match, the position information additional information memory 11 according to the update data included in the update information.
Update the additional information stored in.

As described above, according to the present embodiment, it is possible to update the additional information relating to the position held by the position information transmitting device 102 from the position information host 300 in real time. For this reason, the user can always obtain the latest information from the position information transmitting device 102, and can apply the position information communication system to a service that requires real-time properties. The procedure in which the position information transmitting device 102 transmits the updated contents stored in the position information additional information memory 11 and the position information receiving terminal 202 receives the transmitted position information is exactly the same as the third embodiment. Therefore, they will not be described again here.

In this embodiment, the following modifications are conceivable. That is, the position information transmitting device 102
As shown in FIG. 10, while transmitting the position information (refer to [Table 4]) using the radio wave fs intermittently (within the period “t ₂ ” shown), this position information is not transmitted. At the time (at the beginning of the “t ₁ ” period shown), the location information host 3
From 00, it is checked whether or not the update information is transmitted by the radio wave fm. If the update information is transmitted from the position information host 300, the position information transmitting device 1
No. 02 keeps the receiver 35 and the reception data processing device 35 in the reception state. By performing such time-division processing, the same frequency can be used for the radio wave fm and the radio wave fs (that is, the frequency fm = frequency fs). The power consumption of the transmitting device 102 can be reduced.

Further, the map information database used in the second embodiment may be used in this embodiment. That is,
The map information database 70 shown in FIG. 4 is provided in the position information receiving terminal 202, and the data processing device 51 (see FIG. 6)
To connect to. The data processing device 51 extracts map data corresponding to the position data specified by the collation of the position information database 15 from the map information database 70 and displays the map data on the position information additional information display device 61. By doing so, similarly to the second embodiment, the position of the user and a map indicating the position can be displayed on the screen together.

[Fifth Embodiment] FIG. 11 is a block diagram showing the configuration of a location information communication system according to the present embodiment. The same components as those shown in FIG. 9 (fourth embodiment) are the same. The code is attached. The position information transmission device 103 of the present embodiment replaces the reception data processing device 25 included in the position information transmission device 102 used in the fourth embodiment with the transmission / reception data processing attachment 26 and replaces the transmitter 30 with the transmitter 39. It is something. The position information transmitting device 103a has the same configuration and functions as the position information transmitting device 103.

As in the case of the position information transmitting device 102 of the fourth embodiment, the transmitter 39 provided in the position information transmitting device 103 transmits the position information receiving terminal 2 from the antenna 40 using the radio wave fs.
02 to the location information. In addition, in the position information transmitting device 103, the receiver 35 receives the update information transmitted from the position information host 300 via the antenna 41 by radio wave fm, and the transmission / reception data processing device 26 stores the information in the position information additional information memory 11. The updated additional information is updated with the update data included in the update information.

Here, the update information transmitted by the location information host 300 is composed of an update device number, route information and update data shown in [Table 5] as shown in [Table 6]. Among these, the update device number is an identification number assigned to the position information transmitting device whose additional information stored in the position information additional information memory 11 is to be updated. In the route information, a route to the target position information transmitting device to be updated is obtained from the arrangement of each position information transmitting device and described.
For example, in Table 6, "1", "2",
The update information is sequentially relayed to the position information transmitting device having “3” and “5”, and finally the position information transmitting device having the target identification number “6” (that is, the same number as the update device number). Will be transmitted to

[Table 6]

The transmission / reception data processing device 26 outputs the received update information to the transmitter 39, and the transmitter 39
The update information is transmitted to another position information transmitting device such as the position information transmitting device 103a using m. As described above, the transmitter 39 can transmit the radio wave fm and the radio wave fs.
Among them, the transmission area of the radio wave fs may or may not overlap with the transmission area of another position information transmitting device including the position information transmitting device 103a. On the other hand, the transmission area of the radio wave fm and the transmission area of the radio wave fm emitted by the position information host 300 need to cover at least the adjacent position information transmission device. Therefore, in the case of FIG. 11, the radio wave fm emitted by the position information transmitting device 103
The transmission area of at least the position information transmitting device 103a
Is set in advance so as to cover. Similarly, the transmission area of the radio wave fm emitted by the location information host 300 is at least the location information transmitting device 1
The output radio field intensity of the transmitter 31 (see FIG. 9) is set so as to cover “03”. The transmission area of the radio wave fm and the transmission area of the radio wave fs can be independently set by individually changing the output radio wave intensity of the transmitter 39 according to the radio wave to be transmitted.

To update the additional information stored in the positional information additional information memory 11. On the other hand, if the update device number included in the update information is not its own identification number, the transmission / reception data processing device 26 sends the received update information to the transmitter 39, and transmits the received update information according to the route information included in the update information. The update information is transferred from the antenna 40 to the next position information transmitting device via the device 39.

For example, if the identification number assigned to the position information transmitting device 103 is "1", the position information transmitting device 103 updates the position information transmitting device 103a having the identification number "2" with the update information. To transfer. Thereafter, the update information is sequentially transferred to the subsequent position information transmitting device according to the route information in the update information. Therefore, FIG.
Assuming that the position information transmitting devices 103-1 to 103-7 are given identification numbers "1" to "7", respectively, as shown in FIG. For the device 103-6, the update information is transmitted from the location information host 300 to the location information transmitting device 103-1 to 103.
-2->103-3->103-5-> 103-6, which is relayed like a bucket relay, so that the update information can be transferred to the target location information transmitting device 103-6. . Thereafter, the location information transmission device 103-6 confirms that the update device number included in the update information is the identification number assigned to itself, and stores the identification number in the location information additional information memory 11. The additional information is updated with the update data in the update information.
