Since Bank XX is based on Station A, "A Station", "A Station A Ward", and "A Station I Ward", which are all sections of Station A, are registered in the station name / area name D602, and "XX Bank "
Is registered in the customer name D606, and the homepage screen of the XX Bank is registered in the various data No. D603 as “0022” as data to be displayed on the train display device in the train,
"6: 00-22: 0", which is almost the same as the operation time of each train
"0" is registered as the time designation D605. Based on the registered data, data is distributed for each relay wireless device code D601 corresponding to each station name / area name D602,
Each relay wireless device (including the local relay wireless device) that has received the data stores the data in the RAM area of the memory table shown in FIG. 8 or 7 and wirelessly transmits the data. Then, when the train 101 passing through the track 103 passes near each relay radio device, the data is received and displayed on the train display device.

It should be noted that XX Bank is not limited to all sections of Station A,
It is registered so that the data is also distributed to “Station B”, “Station A”, and “Station C”. This means that each station ("B
Station 101, "station C"), the train 101 stops and the display time on the train display device by data distribution is long, and the "station B"
Can be displayed more efficiently as a commercial because it is close to the section under the control of Station A. Efficient display will differ depending on the priority D607 based on the charging category and the like, and will be described below.

02, "A station" is displayed with a data No. "00" on the display screen in which "XX Ramen" of the customer name D606 becomes a commercial.
23 ". Also, the time designation D605 registers "10: 00-13: 00", and in this time zone, it overlaps with the time zone of XX Bank.
The priority D607 is set to “Hi
gh, “Low”, “Normal”, etc., for example, “Hi”
gh ”, the number of times of data distribution is greater than“ Low ”. For this reason, XX Bank has decided that each station ("A
Station, "B station" and "C station") have higher priority ("Hig
h)), that is, even if a high charge is registered, more efficient display can be achieved by increasing the display frequency (ie, distribution frequency) as a commercial.

As described above, the management center 201 can acquire the information around the station for each station via the Internet network 1006 and distribute the information as related information for each station. As the information around the station, the above-described commercial screen of each company's homepage or store, and further, a guide map around the station, data of public facilities, and the like are distributed as display data, and the train display device in the train or It can be displayed on the premises display device in the station premises.

In the ROM area of FIG. 8 or FIG. 7, fixed data unique to each relay wireless device (including a private relay wireless device) is stored. For example, the indoor relay wireless device 1 of FIG.
In the case of 002, out of the unique fixed data, the number of the next station is specified based on the station name D712 where the local relay radio device is installed and the traveling direction of the train passing through the station. Ascending station code D721 and descending station code D722, and ascending station time D731 and descending station time D73 indicating the time required to reach the next station.
Are transmitted at arbitrary intervals. The train 101 receives these fixed data and displays them at an arbitrary interval on the train display device to determine which station the passenger is currently passing, how long it takes to the next station, etc. Can be visually recognized.

Further, these fixed data are text format data, and the amount of data is extremely small as compared with the above-described image data of a homepage or the like. Therefore, the data is added when other display data such as the image data is transmitted. Both data may be wirelessly transmitted from the relay wireless device.

Further, since the traveling direction of the train 101 and the passing station when traveling on the track 103 are predetermined, data matching the traveling direction of the train 101 can be selected and displayed. For example, in FIGS. 11 and 7, B
In the case of a train that is scheduled to travel from station to station A and is stopped at station B, of the received fixed data, the current station name “station B”, the station name “A station” in the upward direction, and the time required to reach the station in the upward direction “40 minutes” can be displayed on the train display device.

Further, even when it is desired to make the display data different depending on the operating line, the display data can be easily made different depending on the operating line and the operating time zone because the management center performs the collective management. . In particular, since display data can be acquired and distributed using the Internet network, the display data can be changed for each operation line, operation time zone, and each station or region.

Further, a portable radio terminal such as a portable telephone of a passenger who gets on the train can receive and display various data in the train.
