  By such a method, the user can easily know the current position on the route in the portable display device 10. Furthermore, in the portable display device 10, the user can easily know that the transfer station or the getting-off station is approaching, and it is possible to avoid overtaking and the like.

(Timetable information, current position display processing and warning processing by timekeeping section and GPS detection section)
Next, an example of warning processing using latitude and longitude information from the GPS detection unit 23 in the portable display device 10 in addition to the timetable information and the time measurement unit will be described below with reference to the drawings. FIG. 9 is a flowchart illustrating an example of warning processing using a GPS detection unit in the portable display device according to the embodiment of the present invention.

  Note that the flowchart of FIG. 9 is substantially the same as the flowchart of FIG. 4 in steps S11 to S14 and step S16, and the description of the common description is omitted, and only the differences are described.

  That is, the control unit 13 of the portable display device 10 acquires timetable information and the like from the server device S and the like and stores them in the internal storage unit 15 as a result in steps S11 to S14. Next, the control unit 13 of the portable display device 10 performs current position display and warning display using latitude and longitude information from the GPS detection unit 23 in addition to current time information and timetable information from the time measuring unit 22. . That is, the control unit 13 of the portable display device 10 performs a comparison process according to the selected route, boarding station, getting-off station, date and time information of the specified timetable information and the time information from the current time measuring unit 22. (Step S14). Thereafter, for example, in the route 4 of FIG. 6, the position of the train on the current route is displayed on the screen according to the time information from the time measuring unit 22.

That is, the control unit 13 obtains corresponding position information from the time information in the timetable information corresponding to the time information from the time measuring unit 22. That is, as position information by the time measuring unit 22,
Boarding station "Tokyo Station" 12:08
Current position 12:33
The remaining time until arrival at the transfer station is "11 more minutes"
Transfer station "Ogikubo" 12:44
Arrival station "Mitaka station" 12:54
Is shown.

On the other hand, the control unit 13 reads the latitude / longitude information from the GPS detection unit 23 and evaluates the current position (GPS). That is, the control unit 13 uses the route map data included in the timetable information in the internal storage unit 15 and the latitude / longitude information of the station data,
Latitude / longitude information of Tokyo station The latitude / longitude information of Ogikubo station is read, and the two latitude / longitude information and the latitude / longitude information from the GPS detector 23 are compared to calculate which position on the position display screen 18 is obtained. Arrange (step S21).

As a result, for example, the current position (GPS) on the position display screen 18 of FIG. 10 is shown. Here, the current position (GPS) is shown closer to Tokyo Station than the current position (clock) determined from the current time information of the timekeeping unit 22, and it can be seen that the train is behind the timetable.

  Here, the control unit 13 calculates the position of the current process (GPS) in what percentage of the entire process, and multiplies the remaining process% by the total required time, for example, the remaining time until transfer. Is "16 minutes remaining", and in order to display this, the image generation unit 24 generates image information of the remaining time.

  As a result, the user should have run the train 11 minutes before arrival at Ogikubo Station at the transfer station, but the actual train is running 16 minutes before arrival at Ogikubo Station at the transfer station. It can recognize that it is late.

  After that, the control unit 13 warns on a warning screen as shown in FIG. 8 when the time to warn is reached, and in this case, the warning method as described above is possible.

  Further, when the time to warn is reached, the control unit 13 determines how much the position information from the GPS detection unit 23 matches the position information indicated by the time information of the time measuring unit 22 and the timetable information. It is determined whether there is any delay (step S22). If this delay is less than a predetermined value (e.g., about 10 minutes), the control unit 13 considers that the delays match and performs warning processing using the warning screen as shown in FIG. 8 or the warning method as described above. .

  However, if the delay is equal to or greater than a predetermined value (for example, approximately 10 minutes), the control unit 13 regards that the delays do not coincide with each other, and sets the communication unit 27 built in the main body as shown in the flowchart of FIG. Then, the access processing to the server device S on the Internet is performed (step S31). Then, the control unit 13 downloads, from the server device S, delay information, accident information, related time information, etc. regarding the delayed route to the internal storage unit 15 or the like (step S32). Next, the control unit 13 displays the delay information about the route in the internal storage unit 15, the accident information (“There is a personal accident at Asagaya Station, which is a delay of 10 minutes”), related time information, etc. FIG. As shown in FIG. 5, the screen is displayed (step S33).

  At this time, if there is an instruction of the “related timetable” icon by the operation of the operation unit 21 by the user, the related timetable is displayed on the screen, so that the user can obtain time information for recovering the delay of the train. It becomes possible to browse.

  It should be noted that the timing of the processing for accessing the server device S when there is a certain delay in step S22 is also preferably performed before the timing for determining whether or not the time to warn in step S16 has been reached. is there. Thereby, the control part 13 always monitors the delay of a train, and will start access to the server apparatus S if the delay more than fixed time generate | occur | produces.

  As described above, in the mobile display device 10, warning processing using the latitude / longitude information from the GPS detection unit 23 in addition to the timetable information and the timekeeping unit is suitable. With the portable display device 10 that performs this processing, the user can know the delay time of the train from the position on the route according to the current time and the latitude and longitude information from the GPS detection unit 23. Furthermore, it becomes possible to obtain information such as the cause of the train delay, and by browsing the related time information, it is possible to know a method for recovering the delay.
