(A) Processing of Mobile Device 1 FIGS. 5 to 8 are flowcharts showing the processing operation of the mobile device 1, FIGS. 5 to 7 show the flow of the entire process, and FIG. 8 shows the route search process. ing.

In a state where the guide function of the portable device 1 is activated by a predetermined operation, first, as shown in FIG. 5, the user inputs a departure place through the input unit 15 (step A11), and the destination is set. Input (Step A1)
2). Note that the input of the departure place in step A11 is as follows.
For example, when the mobile device 1 has a GPS receiving function, the current location information obtained by the GPS receiving function may be input as the departure place. When the departure place and the destination are inputted, the route search software stored in the route search software storage area 12a of the memory 12 is activated, and the route information including the halfway point from the input departure place to the destination is entered. Is searched (step A13).

Here, referring to FIG.
3 will be described in detail.

As shown in FIG. 8, it is determined whether or not the position information corresponding to the departure place specified first by the user has been received from the nearby information transmitting device 2 which is within the communication range of the portable device 1. (Step B11). If the location information corresponding to the departure place cannot be received (step B
No. 11), the user is out of the correct route, and at that time, the route is corrected by inputting a new departure place (position information at that point) (step B12). If the destination is changed at this time (No in step B13), a new destination is also input (step B14).

When the departure place and the destination are determined, the nearest transportation means is detected from the map data (step B15).
Note that, here, for the sake of simplicity, it is assumed that a train is used as transportation. The map data and a transfer guidance database described later are obtained by route search software, and may be built in the portable device 1 in advance, or may be appropriately read from an external device via a network.

Next, a transit station, a transfer station, and a means of travel to the destination are detected from the transfer guide database to the destination (step B16), and the information on the location of the information transmission device 2 at the transfer station is used to determine the way point. The information (information device type, position information) that can be obtained in step (1) is detected (step B17).

Next, the route from the departure point to the destination is divided (step B18), and for each section i (i indicates the number of divisions), information on the way point i to the way point i + 1, transportation means, passing The device information (information device type, position information) that can be acquired at the station and the waypoint i + 1 is registered in the route information storage area 12b of the memory 12 as the route information (step B1).
9). FIG. 3 shows an example of the route information.

When the route information including the waypoint from the departure point to the destination is obtained in step A13 in FIG. 5, the route guidance processing as shown in FIGS. 6 and 7 is executed. .

That is, as shown in FIG. 6, first, an information transmitting device 2 existing near the portable device 1 owned by the user.
, A communication request is issued (step A14). In this case, communication with the information transmission device 2 is performed by the short-range communication unit 20 shown in FIG. 2, and for example, Bluetooth is used as the short-range communication. If there is a response from the information transmitting device 2 to the communication request from the mobile device 1 (Yes in step A15), the mobile device 1 obtains information device type and position information transmitted from the information transmitting device 2. These are stored in the device information storage area 12c of the memory 12 as device information of the information transmitting device 2 (step A16). The information device type is information indicating the type of the information transmission device 2, and the position information is information indicating the current position of the information transmission device 2. The processing on the information transmission device 2 side will be described later with reference to FIG.

When the information device type and the position information are obtained from the information transmitting device 2 near the portable device 1, it is determined whether or not the position information matches the destination specified by the user (step A17). If the location information obtained from the information transmitting device 2 matches the destination specified by the user (Yes in step A17), it is determined that the user has arrived at the destination. Message has arrived on the display unit 16,
Alternatively, the user is notified by voice output from the voice notification unit 18 (step A18).

On the other hand, when the position information of the information transmitting device 2 does not match the destination specified by the user (step A1).
No. 7), it is determined that the user is at a passing point on the way,
At this time, it is checked whether or not the type of information device obtained from the information transmitting device 2 is “device installed in train” (step A19). As a result, when it is determined that the type of the information device is not “the device installed in the train” and that the current position has changed from the position checked last time (No in step A20), It is checked whether the device is “station-installed equipment” or “road-installed equipment” (step A21).

It is to be noted that "in-train equipment" is obtained as the information equipment type from the information transmitting device 2 in step A19 when the user is moving on a train. This will be described later with reference to FIG. In step A21, "station-installed equipment" or "road-installed equipment" is obtained from the information transmitting device 2 as the information equipment type when the user is walking on the station premises or on the road. Further, information other than the above information can be obtained as the information device type when, for example, the user is moving by car or bus, but the process at that time is omitted here.

If the type of the information device obtained from the information transmitting device 2 is “station-installed device” or “road-installed device” (Yes in step A21), the information transmitting device 2 A matching process is performed between the position information obtained together with the type and the route information registered in the route information storage area 12b of the memory 12 (step A22). If it is determined by this matching process that the route that the user is currently traveling is correct (Yes in step A23),
A message such as "This is the correct route. The next goal is XX" is displayed on the display unit 16, or
The user is notified by voice output by the voice notification unit 18 (step A24).

More specifically, in the example of FIG. 3, if the user is now at the halfway point 1 shown in the section 1, the information transmission device 2 installed at Tachikawa Station sets the information device type to “station”. "Installed equipment" and "Tachikawa station" as position information are obtained. Therefore, the section 1 described in this route information
It can be determined from the information that the user is on the correct route. However, if the user is off the route of section 1, "Tachikawa Station" cannot be obtained as position information. In such a case, it is determined that the route that the user is currently traveling is wrong.

If the route that the user is currently traveling is wrong (No in step A23), for example, a warning is given by a buzzer or vibration provided to the portable device 1 (step A25), and then the message “The route is different. Message is displayed on the display unit 16, or the user is notified by voice output from the voice notification unit 18 (step A26). Then, the place indicated by the current position information is set as the departure place (step A27), and the step A shown in FIG.
The route from the current position to the destination is re-searched by the route search process at 13.

As described above, when the user is walking on foot, the position information sequentially transmitted from the information transmitting device 2 installed in the station yard or on the road determines whether the user is traveling on the correct route. If judged and wrong,
A new route search is performed along with the notification to that effect, and if the vehicle is traveling on the correct route, guidance to the next target is notified.

If the type of information device obtained from the information transmitting device 2 in step A19 is "device installed in train", the following processing is executed.

That is, as shown in FIG. 7, when information of a station different from the station checked last time is obtained as position information from the information transmitting device 2 (No in step A28),
A matching process is performed between the position information and the route information registered in the route information storage area 12b of the memory 12 (step A29). As a result, when it is determined that the vehicle has passed the target station (No in step A30), a message such as "Passing the target station. Perform a search again" is displayed on the display unit 16. Or after the voice notification unit 18 outputs a voice to notify the user (step A31), the route from the current station to the destination is searched again by the route search processing in step A13 in FIG. Is done.

More specifically, in the example of FIG. 3, it is assumed that the user is now heading to “Shinjuku Station” at the halfway point 2 indicated by section 2. In this case, the target station is "Shinjuku Station"
However, if the vehicle accidentally passes through the station, information on the next station is sent to the portable device 1 as position information from the information transmitting device 2 installed in the train. As a result, it is determined that the vehicle has passed the target station (Shinjuku Station), and as described above, a notification such as "You have passed the target station. Perform a search again." Will be

On the other hand, if the position information indicating the station before the target station is obtained, it means that the vehicle has not passed the target station.
In such a case (Yes in step A30), it is determined whether or not the next station is the target station based on the position information at that time. If the next station is not the target station (No in step A32),
The current station name and the number of remaining stations up to the target station are displayed on the display unit 16 as a message or output as voice by the voice notification unit 18 to notify the user (step A33).

When the next station is the target station (Yes in step A32), it is determined whether or not a transfer is necessary according to the route information (step A34). Then, if a transfer is necessary (Ye in step A34)
s), a message such as "Next is XX station. Please get off. Transfer is XX line."

Communicates with you to guide you along a new route,
Anyone can go to the destination without fail.

Although the above embodiment has been described on the assumption that a train is used as a means of transportation, the same applies to a case where a bus is used, for example, and the communication with the information transmitting device 2 installed on the bus. It is also possible to provide route guidance to the destination.

Further, when using a car, when the car is running, information is received from the information transmitting device 2 installed in the car and route guidance is performed. For example, the user gets off the car on the way and walks or goes on a train. In the case of a transfer to a destination, the user can continue to receive information from another information transmission device 2 installed on a road, a train, or the like, and provide route guidance. Therefore, unlike a conventional car navigation system, a road guidance system not limited to the inside of a car can be realized.

In the above embodiment, the information transmitting device 2
Transmitted only the information device type and position information of the mobile device 1 in response to a communication request from the mobile device 1. Processing such as displaying the map along with the current position of the user is also possible.
