[Flow of mobile phone terminals during navigation processing]
FIG. 3 shows a schematic flowchart of navigation processing executed by the control unit 40 by the navigation program 49 of the memory unit 45 in the mobile phone terminal 11 of the present embodiment. Note that the flowchart of FIG. 3 shows an example of navigation processing in the case of using transportation between routes from the departure point to the destination, and in particular, the basic processing flow for the portion using transportation Is shown. In the example of the flowchart of FIG. 3, route information and map information from the departure point to the destination have already been obtained by route search in the route search server 10, and the transportation facility used in the route Get information about routes, boarding stations and station platforms, boarding / departure station information, train / car schedule information, station / home unique numbers, unique boarding / departure numbers, train unique numbers and vehicle unique numbers Such information is stored in the memory unit 45.

  In FIG. 3, the control unit 40 of the mobile phone terminal 11 performs the route information obtained from the route search result in the route search server 10 as a process of step S <b> 1 from the departure place to the boarding station of the transportation facility. Navigation using the map information and the GPS information from the GPS unit 54 is performed.

  As a result of the navigation in step S1, when the user arrives at the boarding station and confirms that the user has entered the boarding station and moved to the vicinity of the station platform, for example, based on the GPS information of the GPS unit 54, the control unit 40, as the process of step S2, through the short-range wireless communication unit 55, the station / home unique number and each unique number that are short-range wirelessly communicated from the landing RF tag 13 provided at the station platform of the station Get information on boarding / departure unique numbers.

  Next, the control unit 40 has acquired from the station / home unique number and the platform unique number already acquired by the route retrieval in the route retrieval server 10 and accumulated in the memory unit 45, and the platform RF tag 13. By comparing the station / home unique number and the boarding / departure unique number, it is determined whether or not the station platform and the boarding / exiting location where the user is present is a correct boarding place. That is, the control unit 40 determines whether or not the station / home unique number and the landing unique number in the memory unit 45 match the station / home unique number and the landing unique number from the landing RF tag 13.

  And when those numbers correspond (when it is a right boarding place), the control part 40 is the boarding through the display display of the display part 43, the sound output from the speaker 50, the vibration of a vibrator, etc., for example. After notifying the user that the field is correct, the process proceeds to step S4. On the other hand, if the numbers do not match, the control unit 40 notifies the user that the boarding place is not correct, for example, through display on the display unit 43, sound output from the speaker 50, vibration of the vibrator, or the like. At the same time, navigation for guiding the user to the correct boarding area is performed, and the process returns to step S2.

  When it is determined in step S3 that the boarding area is correct and the process proceeds to step S4, the control unit 40 performs short-range wireless communication from the train / vehicle RF tag 12 provided for each train and each vehicle. An attempt is made to acquire information on the train unique number and the vehicle unique number through the short-range wireless communication unit 55. In this example, when the process proceeds from step S3 to step S4, the acquisition of the train unique number and the vehicle unique number information is started immediately. For example, it almost coincides with the operation schedule of the scheduled train. You may make it start acquisition of the said train specific number and vehicle specific number information after time comes. As described above, if the short-range wireless communication unit 55 is not operated until the time approximately coincident with the operation schedule of the scheduled train, the battery consumption of the mobile phone terminal 11 can be reduced. In addition, when a user gives an instruction to acquire train unique number and vehicle unique number through the operation unit 44, the train unique number and vehicle unique number information from the train / vehicle RF tag 12 is stored in the short distance. You may make it start the operation | movement acquired through the wireless communication part 55. FIG.

  Then, when the user gets on the train, the train unique number and the vehicle unique number information that are short-range wirelessly communicated from the train / vehicle RF tag 12 can be acquired through the short-range wireless communication unit 55, The control unit 40 acquires from the train / vehicle RF tag 12 the train unique number and the train unique number that have already been acquired by the route search in the route search server 10 and accumulated in the memory unit 45 as the process of step S5. By comparing the train unique number and the vehicle unique number, it is determined whether the train on which the user has boarded and whether or not the vehicle is a correct train and vehicle. That is, the control unit 40 determines whether the train unique number and the vehicle unique number in the memory unit 45 match the train unique number and the vehicle unique number from the train / vehicle RF tag 12.

  When the numbers match (when the train and vehicle are correct), the control unit 40 transmits the train and vehicle through the display on the display unit 43, sound output from the speaker 50, vibration of the vibrator, and the like. After passing the message to the user to the effect, the process proceeds to step S6. On the other hand, if the numbers do not match, the control unit 40 notifies the user that the train or vehicle is incorrect, for example, through the display on the display unit 43, sound output from the speaker 50, vibration of the vibrator, or the like. In addition, navigation for guiding the user to the correct train or vehicle is performed, and the process returns to step S4. If only the train unique number matches and the vehicle unique number does not match, the user is notified that the vehicle is not the correct vehicle, and the correct vehicle is not Only the notification of whether the vehicle number arrives at the nearest place) may be performed, and the navigation for guiding the user to the correct vehicle may not be performed.

  When it is determined in step S5 that the train / vehicle is correct and the process proceeds to step S6, the control unit 40 passes through the short-range wireless communication unit 55 every time the train stops at the station. To obtain information on the station / home unique number and each landing / departure unique number for short-range wireless communication. Here, in this embodiment, whether or not the train has stopped at the station can be determined from GPS information of the GPS unit 54, for example. That is, when the control unit 40 detects that the movement of its own terminal has stopped based on the GPS information of the GPS unit 54, the control unit 40 determines that the train has stopped at the station, and the station / home-specific information is transmitted through the short-range wireless communication unit 55. The information acquisition operation of the number and each boarding point unique number is started. In addition, the information acquisition operation of the station / home unique number and the platform specific number through the short-range wireless communication unit 55 is performed when the train stops at the station based on the operation schedule of the train. May be. However, since trains do not always operate according to the operation schedule, when information acquisition is performed based only on the operation schedule, a margin of a certain time before and after the station stop time determined by the operation schedule. It is desirable to take the information acquisition operation.

  Next, when the train stops at the station or the like, the station / home unique number and the platform unique number that are short-distance wirelessly communicated from the landing / RFID tag 13 of the station platform's landing / departure are obtained from the short-distance wireless communication. When it can be acquired through the unit 55, the control unit 40, as the process of step S7, acquires the station / home unique number and the landing point unique number that have already been acquired by the route search in the route search server 10 and accumulated in the memory unit 45. And the station / home unique number acquired from the landing RF tag 13 and the landing unique number, it is determined whether the station platform / departure point at which the train currently stops is a correct getting-off point. Judgment is made. That is, the control unit 40 determines whether or not the station / home unique number and the boarding / departure unique number in the memory unit 45 match the station / home unique number and the landing / equivalent number from the landing RF tag 13.

  And the control part 40 advances a process to step S9, when those numbers correspond (when it is a correct getting-off place). On the other hand, if the numbers do not match, the control unit 40 indicates that the user has not yet arrived at the correct getting-off place through the display on the display unit 43, the sound output from the speaker 50, the vibration of the vibrator, or the like.

For example, through the display on the display unit 43, the sound output from the speaker 50, the vibration of the vibrator, etc., the route for returning to the target drop-off point and notifying the user that the target drop-off point has already passed. After performing the search again, the process returns to step S2. As a result, in step S2 and subsequent steps in this case, the same processing as described above is performed for the route after the re-search.

  If it is determined in step S7 that the vehicle is a correct getting-off place and the process proceeds to step S9, the control unit 40 acquires the nearest getting-off station nearest to the destination already acquired by route search and stored in the memory unit 45. By comparing the station / home unique number and the boarding / departure unique number with the station / home unique number and the boarding / departure unique number obtained from the above-described landing RF tag 13, the getting-off station gets off at the nearest station of the destination. It is determined whether it is a place.

  And the control part 40 advances a process to step S10, when those numbers correspond (when it is the nearest getting-off station station of a destination). On the other hand, if the numbers do not match, the control unit 40 informs the user that the station is a transfer station, for example, through display on the display unit 43, sound output from the speaker 50, vibration of the vibrator, and the like. After notifying and giving the train transfer guidance to the user, the process returns to step S2. Thereby, in step S2 and subsequent steps in this case, the same processing as described above is performed on the route after the transfer.

  If it is determined in step S9 that the station is the nearest stop station at the destination and the process proceeds to step S10, the control unit 40 then searches the route search server 10 for the route from the stop station to the destination. Navigation is performed using the route information and map information obtained as a result, and the GPS information from the GPS unit 54.
