It is a figure which shows the example of the route information which 2 hold | maintains. FIG. 8 is a diagram showing an example of route information held by the sign apparatus (sign ID: 20101) 2 corresponding to the floor moving means shown in FIG.

  It is assumed that the destination selected by the user is “restaurant A (identification ID of the corresponding sign device 2: 10213)” on the second floor shown in FIG.

  In this case, according to the route information shown in FIG. 7A, the sign device 2 (identification ID: 10101) passes next on the route to the destination “restaurant A” (identification ID: 10213). It can be seen that the route information “45 (northwest)” indicating the “direction” to the marking device 2 (shown in FIG. 3 as the labeling device having the identification ID: 10103) is held.

  Next, according to the route information shown in FIG. 7B, the sign device (identification ID: 10103) 2 uses the next sign for the route to the destination “restaurant A” (identification ID: 10213). It can be seen that the route information “45 (northwest)” indicating “direction” to the device 2 (shown in FIG. 3 as a marker device having an identification ID: 20101) is held.

  Further, as shown in FIG. 8, the sign device (identification ID: 20101) 2 corresponding to the floor moving means (in this case, the elevator) 2 is the sign device 2 that passes next on the route to the destination “restaurant A”. It can be seen that the route information of “second floor (2F)” indicating the destination is held instead of the value as “direction” to

  Further, in the sign device 2 corresponding to the destination, it is assumed that no value is set in the “direction” of the route information to the destination in the route information held by the self-sign device 2, and in the route information shown in FIG. , “−”.

  The data communication unit 21 performs wireless communication, acquires destination information and route information from the management device 4 or another sign device 2, and stores them in the data storage unit 20.

  In addition, when the data communication unit 21 performs wireless communication and receives a guidance request from the user terminal 3, the data communication unit 21 transmits destination information to the user terminal 3 that has made the guidance request. When the data communication unit 21 receives a destination name (identification information) desired to be guided from the user terminal 3, the data communication unit 21 transmits route information corresponding to the received destination name to the user terminal 3 that has requested the guidance.

  As shown in FIG. 5, the user terminal 3 is a terminal carried by a user who is to receive guidance, the guidance information display device 30, a direction acquisition unit 310 that acquires the direction in which the user terminal 3 is facing, And a display portion 311 on which information is displayed. The user terminal 3 is a terminal such as a mobile phone or a PDA (Personal Data Assistance). As the identification ID of the user terminal 3, MAC address information of the data communication unit 32, a mobile phone number of the user terminal 3, a unique number of the mobile terminal, and the like are used.

  The data storage unit 31 stores the destination information, the selected destination, the identification ID of the sign device in communication, the route information, etc. acquired via the data communication unit 32.

  The data communication unit 32 performs wireless communication with the sign device 2 located at the shortest distance with the own user terminal 3 and stores the acquired information in the data storage unit 31. When the data communication unit 32 communicates with the new marker 2, the data communication unit 32 stores the acquired data in the data storage unit 31 and updates the data.

  When the destination selection / determination unit 33 acquires the destination information from the sign device 2, the destination selection / determination unit 33 displays a list of destinations included in the destination information on the display unit 311. When the user selects a destination requesting guidance from the displayed list of destinations, the identification ID of the marking device 2 corresponding to the destination is selected as the selected destination via the data communication unit 32. Send to. Further, the identification ID of the sign device 2 corresponding to the selected destination is stored in the data storage unit 31.

  In addition, the destination selection / determination unit 33 includes the direction calculation unit 34 and the guidance display processing unit 35 when the sign device 2 with which the data communication unit 32 communicated is the sign device 2 corresponding to the selected destination. The processing is stopped and a predetermined message is displayed on the display unit 311.

  The direction calculation unit 34 acquires the direction α (the direction to the next sign device 2 corresponding to the selected destination) from the route information stored in the data storage unit 31. Then, based on the direction α and the direction β of the user terminal 3 acquired by the direction acquisition unit 310, the display angle θ of the guidance arrow is calculated.

  The direction β of the user terminal 3 is represented by an angle shown counterclockwise from the reference axis indicating the front of the user terminal 3.

  The direction calculation unit 34 acquires the direction β of the user terminal 3 from the direction acquisition unit 310 every time the update timer 36 notifies the elapse of a predetermined time. Then, the difference (α−β) between the direction α of the route information stored in the data storage unit 31 and the direction β of the user terminal 3 is obtained and set as the display angle θ. When the difference (α−β) is negative, 360+ (α−β) is set as the display angle θ.

  For example, if the direction α of the route information is “45” and the direction β of the user terminal 3 is “270”, the display angle θ is “135”, and if the direction β of the user terminal 3 is “0”. , The display angle θ is “45”.

  The guidance display processing unit 35 generates display data of a guidance arrow that is tilted counterclockwise by the display angle θ from the reference axis that indicates the front of the user terminal 3 and displays the display data on the display unit 311.

  The update timer 36 detects a predetermined elapsed time (for example, 5 seconds) and notifies the direction calculation unit 34 of it.

  The direction acquisition unit 310 is implemented by a known electronic compass function, and acquires the direction β facing the user terminal 3 every predetermined time.

  The display unit 311 is implemented by a known display unit function, and displays a guidance arrow generated by the guidance display processing unit 35.

  In the user terminal 3, when the data communication unit 32 moves to a communicable range of the sign device 2, the data communication unit 32 communicates with the sign device 2, acquires route information of the selected destination, and sends it to the data storage unit 31. Store. Further, when communication with the new sign device 2 becomes possible, new route information is acquired. The direction calculation unit 34 calculates the display angle θ while a value is set in the direction of the route information stored in the data storage unit 31, and the guidance display processing unit 35 displays an arrow tilted at the display angle θ. Repeat the process of displaying.

  In this embodiment, the destination selection / determination unit 33 determines that the vicinity of the destination has been reached, but the direction calculation unit 34 sets a value in the direction of the route information stored in the data storage unit 31. If not, it is determined that the sign device 2 that has transmitted the route information corresponds to the destination, and the calculation process of the display angle θ and the display process of the guidance arrow are terminated. Good.

  When it is determined that the vehicle is approaching the destination, the guidance display processing unit 35 displays a message such as “near the destination” on the display unit 311.

  As shown in FIG. 9, when the user terminal 3 is within the communicable range of the two sign devices 2, the data communication unit 32 stores the route information acquired from the sign device 2a that is already communicating. Continue to hold in part 31. Then, when the user moves in the overlapping communicable range and the user terminal 3 comes to be located in the radio wave reception range of the sign device 2b, the data communication unit 32 starts communication with the sign device 2b, Route information is acquired from the marking device 2b and the data storage unit 31 is updated. This is because if the route information is updated immediately after entering the communicable range with the sign device 2b, the display switching timing of the guidance arrow on the display unit 311 is too early and appropriate guidance cannot be performed.

  FIG. 10 is a diagram illustrating an example of a block configuration of the management device 4 and the data generation device 5.

The information is received and stored in the route information storage unit 42, and the update information of the route information is transmitted to the corresponding marking device 2.

  The management device 4 receives the destination information and the route information transmitted from the data generation device 5 and stores them in the destination information storage unit 41 and the route information storage unit 42, respectively.

  When the data distribution unit 43 transmits the destination information and the route information to the sign device 2P on each floor, the sign device 2P transmits these pieces of information to the sign device 2C under the network. The data distribution unit 43 may collectively transmit information to all the labeling devices 2 of the indoor guidance system 1, or may individually transmit information to a specific labeling device 2. Alternatively, the labeling device 2P may transmit information to the marker device 2C located nearby, and the marker device 2C that has received the information may transfer the information to another marker device 2C.

  The data generation device 5 is a device that generates data used in the indoor guidance system 1, and includes a sign device information generation unit 50, a destination information generation unit 51, a route information generation unit 52, and a data output unit 53. With.
