  FIG. 1 shows a navigation system 1 according to this embodiment. The navigation system 1 is a system that shows a route (route) that the user U moves on foot or the like and navigates (guides) the user U. For example, the navigation system 1 navigates the user U from the entrance of a place where a seat serving as a navigation area is provided to a designated seat in a venue with a designated seat such as a theater, a movie theater, or a concert venue.

  As shown in FIG. 1, the navigation system 1 includes a check-in machine 10, a route distribution machine 20, a lighting device 30, and a terminal 40. Among these configurations, the check-in machine 10, the route distribution machine 20, and the lighting device 30 are devices that are installed in advance in a venue where navigation is performed. The terminal 40 is a device carried by the user U as a navigation target, and specifically corresponds to a smartphone or the like.

  The check-in machine 10 checks in the user U with the terminal 40. Check-in is a procedure for entering a venue such as a theater, a movie theater, or a concert venue. The check-in machine 10 includes a housing, and is installed at a position slightly away from the place where the seat is provided, for example, immediately after entering the venue.

  The route distributor 20 is a device that calculates a route for navigating the user U. The route distributor 20 has a housing and is installed at the entrance / exit of a place where a seat, which is a navigation area, is provided. Note that a plurality of entrances / exits of the place may be provided, and a plurality of route distributors 20 may be provided for each entrance / exit. When a plurality of route distributors 20 are provided, information can be transmitted and received between the route distributors 20, and information stored in the route distributor 20 described later is synchronized to distribute all routes. Is stored in the machine 20.

  The lighting device 30 is a device that navigates the user U by lighting up. That is, the lighting device 30 performs display indicating the route. The lighting device 30 is positioned and provided in an area where navigation is performed. For example, the lighting device 30 is positioned and embedded in a passage where a seat is provided. A plurality of lighting devices 30 are provided, and the lighting devices 30 provided on the route of the user U are lit. As shown in FIG. 1, identifiers (“101”, “102”, “AA”, “AB”, etc.) corresponding to the embedded position are set in the lighting device 30. Although not shown in FIG. 1, the lighting device 30 is also embedded at the position where the route distributor 20 is provided. The user U can grasp how to move to his designated seat by referring to the lighting. That is, the navigation system 1 is a system related to navigation using the lighting device 30. Note that the lighting device 30 is not necessarily included in the navigation system 1 as a component of the present invention (that is, the navigation system 1 can be realized as an invention that does not include the lighting device 30).

  An outline of navigation of the user U by the navigation system 1 will be described. The user U entering the venue holds his / her terminal 40 over the check-in machine 10. Thereby, a check-in process is performed. Subsequently, the user U walks to the location of the route distributor 20 and holds his / her terminal 40 over the route distributor 20. After that, when the user U enters a place where a seat, which is a navigation area, is provided, the lighting device 30 provided on the route to the designated seat of the user U is lit, indicating the route to the user U.

  Subsequently, functions of the check-in machine 10, the route distributor 20, the lighting device 30, and the terminal 40 included in the navigation system 1 according to the present embodiment will be described with reference to FIG. As shown in FIG. 2, the check-in machine 10 includes a check-in processing unit 11.

  The check-in processing unit 11 is a unit that receives a check-in request from the terminal 40 and performs check-in processing. The check-in processing unit 11 performs short-range wireless communication with the terminal 40 and performs check-in processing. For example, near field communication such as NFC (Near Field Communication) having a communication distance of about several centimeters to several tens of centimeters is used for the near field wireless communication. As described above, the short distance wireless communication is performed by the user U holding the terminal 40 over the check-in machine 10 (the distance between the terminal 40 and the check-in machine 10 becomes a communicable distance).

  The check-in processing unit 11 receives a check-in request from the terminal 40. The check-in request includes check-in information including reserved seat information that specifies the reserved seat of the user U of the terminal 40. When the check-in processing is completed, the check-in processing unit 11 distributes the designated seat information included in the check-in information received from the terminal 40 and information indicating the check-in time that is the time when the check-in is performed. To the machine 20. The reserved seat information is information corresponding to the destination of the user U. Information indicating the check-in time is information used to calculate the moving speed of the user U.

  Note that the check-in machine 10 and the route distribution machine 20 are connected by wire or wireless so that information can be transmitted and received between them. Further, information for identifying the terminal 40 such as a terminal ID is set in the terminal 40 in advance. When information is transmitted / received between the terminal 40 and the check-in machine 10 and the route distributor 20, information specifying the terminal 40 is also transmitted / received. In the check-in machine 10 and the route distributor 20, Processing can be performed for each terminal 40.

  As shown in FIG. 2, the route distributor 20 includes a route creation unit 21, a recreation determination unit 22, a recreation control unit 23, a route transmission unit 24, and a lighting time correction determination unit 25. Has been.

  The route creation unit 21 is display information acquisition means for acquiring display information indicating the display position and time for each of the plurality of users U by the lighting device 30. The route creation unit 21 acquires information indicating the departure place, destination, and departure time of the user U, calculates the route of the user U based on the acquired information, and displays the information by the lighting device 30 according to the route. Display information is created (acquired) by calculating the position and the time of. The route creation unit 21 acquires information indicating the moving speed for each user U, and calculates the display time by the lighting device 30 based on the moving speed indicated by the information. The route creation unit 21 acquires display information that also indicates a display method (for example, display color in the present embodiment) other than the display position and time.

  FIG. 3 shows display information created by the route creation unit 21. As shown in FIG. 3, the display information is information in which a current location flag, a route, a lighting color, a scheduled lighting time, a scheduled passing time, an actual passing time, and a scheduled turn-off time are associated with each other. Each record of display information (corresponding to one line in FIG. 3) corresponds to one lighting device 30. Moreover, it corresponds to the lighting device 30 corresponding to the route of the user U in order from the top of the display information.

  The current location flag is a flag indicating the current location of the user. At the time of route creation, the current location flag is provided at the location of the route distributor 20 that is the departure location. Also, information indicating the position of the route distributor 20 that is the departure point is stored in the current location flag column of the first record of the display information, and the destination ( Information indicating the corresponding position of the reserved seat of the user U is stored. The route is an identifier of the lighting device 30 that is lit. The lighting color is the lighting color of the lighting device 30. For example, five colors of white, red, blue, yellow, and green are used as lighting colors. The scheduled lighting time is a time when lighting of the lighting device 30 is started. The scheduled passage time is a time when the user U is scheduled to pass the position of the lighting device 30. The actual passage time is a time when the user U actually passes the position of the lighting device 30. The scheduled turn-off time is the time when the lighting device 30 is turned off.

  The route creation unit 21 creates display information as follows. The route creation unit 21 receives the reserved seat information and information indicating the check-in time transmitted from the check-in machine 10. In addition, the route creation unit 21 performs short-range wireless communication with the terminal 40. The short-distance wireless communication here is, for example, one having a communication distance of about several cm to several tens of cm such as NFC. As described above, the short distance wireless communication is performed by the user U holding the terminal 40 over the route distributor 20 (the distance between the terminal 40 and the route distributor 20 becomes a communicable distance). The route creation unit 21 sets the time when the short-range wireless communication is started with the terminal 40 as the time when the user U reaches the position of the route distributor 20.

  The route creation unit 21 specifies the lighting device 30 that is the destination of the route from the reserved seat information. The route creation unit 21 stores the lighting device 30 that is the destination of the route in advance corresponding to each seat, and performs the above specification based on the information. The route creation unit 21 calculates a route to the identified destination using the position of the lighting device 30 provided at the same place as the position of the own device 20 as a departure point. The route creation unit 21 stores a positional relationship (adjacent relationship) between the lighting devices 30 in advance, and calculates a route based on the information. The calculation of the route is performed using, for example, a conventional technique. As a result of the calculation, the identifier and the order of the lighting device 30 on the route to the destination are obtained. That is, information corresponding to the route of the display information shown in FIG. 3 (the order of the identifiers of the lighting devices 30) is obtained.

  Further, the route creation unit 21 calculates the moving speed of the user U as follows. The route creation unit 21 subtracts the check-in time from the time when the user U arrives at the position of the route distributor 20, thereby calculating the time (Y seconds) required to move from the check-in device 10 to the route distributor 20. calculate. The route creation unit 21 divides the distance (X (m)) from the check-in machine 10 to the route distributor 20 stored in advance by this time (Y (seconds)) to obtain a moving speed (average walking speed) ( X / Y (m / sec)) is calculated.

  The route creation unit 21 calculates the estimated transit time of the position of each lighting device 30 on the route calculated as described above based on the calculated moving distance. First, the route creation unit 21 sets the estimated transit time for the current location (the position of the route distributor 20, the position of the lighting device 30 of “100” in the example of FIG. 3) as the time of reaching the position of the route distributor 20. To do. Subsequently, the route creation unit 21 divides the distance (D) between the lighting device 30 to be calculated and the previous lighting device 30 on the route by the calculated moving speed (S). The time (T = D / S) required from the lighting device 30 to the lighting device 30 to be calculated is calculated. The route creation unit 21 stores the distance (D) between the lighting devices 30 in advance. The scheduled passage time of each lighting device 30 is calculated by adding the time to the scheduled passage time of the previous route distributor 20.

  In the example of FIG. 3, the distance (D1) from the position of the lighting device 30 of “100” (position of the route distributor 20) to the position of the lighting device 30 of “101” that is the next lighting device 30 is the moving speed. Divide by (S) and calculate the time (T1 = D1 / S, 5 seconds) required until the lighting device 30 of “101”. The calculated passage time of the lighting device 30 of “101” is calculated as 20:00:05 by adding the calculated 5 seconds to the scheduled passage time of 20:00 of the lighting device 30 of “100”. Further, the distance (D2) from the position of the lighting device 30 of “101” to the position of the lighting device 30 of “102” that is the next lighting device 30 is divided by the moving speed (S), and the lighting device of “102” The time taken to 30 (T1 = D2 / S, 2 seconds) is calculated. The calculated passage time of the lighting device 30 of “102” is calculated as 20:00:07 by adding the calculated 2 seconds to the scheduled passage time 20:00:05 of the lighting device 30 of “101”. In this way, the planned transit time is sequentially calculated up to the lighting device 30 at the destination.

  The route creation unit 21 calculates the scheduled turn-off time of the lighting device 30 by adding a preset fixed value (for example, 5 seconds) to the scheduled passage time of each lighting device 30. In addition, the route creation unit 21 determines the lighting device 30 (for example, “100”, “100” in the example of FIG. 3) within a preset time (for example, within 10 seconds) from the scheduled passage time of the first lighting device 30. The scheduled lighting time of the lighting devices 30) of “101”, “102”, and “103” is the time when the position of the route distributor 20 is reached. Alternatively, the scheduled lighting time of a predetermined number (for example, five) of lighting devices 30 from the beginning on the route may be the time when the position of the route distributor 20 is reached. Thus, the first few devices start lighting at the same time.

  The route creation unit 21 sets the scheduled lighting time of each of the lighting devices 30 thereafter as the scheduled lighting time of each of the lighting devices 30 in the order of the route after the first lighting device 30. For example, in the example of FIG. 3, the scheduled lighting times of the lighting devices 30 of “104”, “105”, “106”... Are the scheduled lighting times of the lighting devices 30 of “100”, “101”, “102”. To do. That is, every time one lighting device 30 is turned off, the next lighting device 30 is turned on.

  The route creation unit 21 sets the lighting color to a preset color. The lighting color candidates are determined with priorities. For example, the first priority is white, the second is red, the third is blue, the fourth is yellow, and the fifth is green. The route creation unit 21 sets the lighting color as the lighting color with the first priority. The route creation unit 21 sets the actual passing time of the first lighting device 30 (the lighting device 30 at the position of the route distributor 20) as the time when it reaches the position of the route distributor 20. Other actual transit times are left blank. As described above, the route creation unit 21 creates display information.

  The route creation unit 21 outputs the created display information to the re-creation determination unit 22 as temporary route display information. Also, the route creation unit 21 re-creates display information (reroute execution) when an instruction is received from the re-creation control unit 23. The re-creation will be described later.

  The re-creation determination unit 22 is a determination unit that compares the display information of each of the plurality of users U created by the route creation unit 21 to determine whether or not the route needs to be recalculated. The re-creation determination unit 22 stores display information (determined route display information) actually used for the navigation of the user U. Display information that is actually used is display information transmitted from the route transmission unit 24 to the terminal 40 (and the following correction is not approved) or transmitted from the route transmission unit 24 to the terminal 40 as described later. The display information is approved after the scheduled lighting time and the scheduled lighting time are corrected.

  When the display information of the provisional route is input from the route generation unit 21, the re-creation determination unit 22 compares the input display information with the stored display information on another user U. Specifically, the re-creation determination unit 22 determines the lighting color of each lighting device 30 in the provisional route display information and the time zone from the scheduled lighting time to the scheduled lighting time relating to another user U stored therein. It is determined whether all the display information of the route overlaps the lighting color of each lighting device 30 and the time zone from the scheduled lighting time to the scheduled lighting time. Note that if any part of the time zone overlaps, it is determined that the part overlaps. The above determination is to determine whether or not lighting by the lighting device 30 relates to a plurality of route displays (whether or not lighting by the lighting device 30 overlaps a plurality of routes).

  If the re-creation determination unit 22 determines that the display information of the temporary route does not overlap with the display information of any confirmed route, the re-creation determination unit 22 stores the display information of the temporary route as the display information of the determined route and the route transmission unit 24. Output to. If the re-creation determination unit 22 determines that the display information of the temporary route overlaps with the display information of any confirmed route, the re-creation determination unit 22 changes the lighting color of the display information of the temporary route to the next priority color. For example, if it is determined that duplication has occurred in white with the first priority, the lighting color is changed to red with the second priority. The re-creation determination unit 22 performs the above-described overlap determination again using the display information whose lighting color is changed as the display information of the temporary route.

  If the re-creation determination unit 22 determines that the display information of the temporary route does not overlap with the display information of any confirmed route, the re-creation determination unit 22 stores the display information of the temporary route as the display information of the determined route and the route transmission unit 24. Output to. If the re-creation determination unit 22 determines that the display information of the temporary route overlaps with the display information of any confirmed route, the re-creation determination unit 22 further changes the lighting color of the display information of the temporary route to the next priority color. The same determination as above is performed.

  The re-creation determination unit 22 determines that the display information of the provisional route overlaps with the display information of any confirmed route even when the above determination is made for all the lighting colors (colors of the last priority order). Then, it is determined that the route needs to be recalculated, and the fact is notified to the recreation control unit 23.

  The re-creation control unit 23 is a re-calculation control unit that controls to re-calculate the route based on the determination by the re-creation determination unit 22. When the re-creation control unit 23 receives notification from the re-creation determination unit 22 that the route re-calculation is necessary, the re-creation control unit 23 instructs the route creation unit 21 to re-create the route (requests re-routing). .

  When the route creation unit 21 receives a route re-creation instruction from the re-creation control unit 23, the route creation unit 21 calculates a route different from the route determined to overlap with the display information of the confirmed route related to another user U, and creates a new route. Generate display information. The route creation unit 21 outputs the recreated display information to the recreation determination unit 22 as display information of the temporary route. The re-creation determination unit 22 performs the same processing as described above for the re-created display information.

  The route transmission unit 24 is a unit that transmits the display information of the confirmed route input from the re-creation determination unit 22 to the terminal 40. The route transmission unit 24 transmits display information to the terminal 40 by a method similar to the method by which the route creation unit 21 communicates with the terminal 40, that is, short-range wireless communication such as NFC. For example, the route transmission unit 24 may transmit display information to the terminal 40 by leaving the terminal 40 held over the route distributor 20. Therefore, for example, when the transmission of the display information is completed, a sound or an image indicating that may be output so that the user U can grasp that the display information has been transmitted to the terminal 40.

  The lighting time correction determination unit 25 is a unit that determines whether to approve or reject (reject) the corrected display information transmitted from the terminal 40 as the correction route approval request. The corrected display information is display information in which the terminal 40 corrects the scheduled lighting time and the scheduled light-off time of the display information created by the route creation unit 21 as described above. The corrected display information will be described later in more detail. The lighting time correction determination unit 25 receives the corrected display information transmitted from the terminal 40. Information transmission / reception with the terminal 40 at this time is performed by wireless communication such as Bluetooth (registered trademark) or wireless LAN.

  The lighting time correction determination unit 25 refers to the display information relating to another user U stored by the re-creation determination unit 22, and the lighting color and the scheduled lighting time of each lighting device 30 in the received corrected display information. Whether or not the time zone from the scheduled lighting time to the scheduled lighting time overlaps with the lighting color of each lighting device 30 and the time zone from the scheduled lighting time to the scheduled lighting time of all the display information of the confirmed route relating to another user U to decide. This determination is performed in the same manner as the determination by the re-creation determination unit 22.

  When the lighting time correction determination unit 25 determines that the corrected display information does not overlap with any of the confirmed route display information, the lighting time correction determination unit 25 approves the corrected display information. In that case, the lighting time correction determination unit 25 causes the re-creation determination unit 22 to store the corrected display information as display information of the confirmed route instead of the display information before correction. At this time, the record (information on the part that the user has passed) before the record provided with the current location flag may be discarded and stored in the re-creation determination unit 22. For example, in the example of the display information in FIG. 4, records whose routes are “100” to “103” may be discarded. Thereby, the risk of route duplication can be reduced. Further, when the corrected display information is approved, the lighting time correction determination unit 25 transmits information indicating that the corrected display information is approved to the terminal 40.

  If the lighting time correction determination unit 25 determines that the corrected display information overlaps with the display information of any confirmed route, the lighting time correction determination unit 25 rejects the corrected display information. In that case, the lighting time correction determination unit 25 transmits information indicating that the corrected display information is denied to the terminal 40.

  As shown in FIG. 2, the lighting device 30 includes a lighting unit 31 and a passage detection signal transmission unit 32.

  The lighting unit 31 is a unit that performs lighting that is a display indicating a route. For example, the lighting unit 31 includes a light. The light can be lit (emitted) in a plurality of colors corresponding to the above-described lighting colors. Note that the light itself may be capable of lighting in multiple colors, or the light itself is a single color (white light), and a film corresponding to the lighting color is provided, and lighting in multiple colors is possible by controlling the lighting position. May be possible. The lighting unit 31 receives a control signal from the terminal 40 and performs lighting in the lighting color and time zone indicated by the control signal.

  The passage detection signal transmitter 32 has passed through the position of the terminal 40 (the user U who carries it) (the position above the position where the terminal 30 is embedded) (the terminal 40 is connected to the terminal 30). It is means for transmitting a passage detection signal used for detecting that the position has been reached. The signal is, for example, a signal for IMES (Indoor Messaging System), and a conventional signal is used. The passage detection signal transmission unit 32 always transmits a passage detection signal. Alternatively, the passage detection signal transmission unit 32 may transmit the passage detection signal when the lighting unit 31 is lit.

  As illustrated in FIG. 2, the terminal 40 includes a check-in request unit 41, a route reception unit 42, a device control unit 43, a device passage detection unit 44, and a lighting time correction unit 45. Note that the terminal 40 may have a function that a smartphone or the like normally has, in addition to the function according to the present embodiment.

  The check-in request unit 41 is means for requesting the check-in machine 10 to check in. The check-in request unit 41 stores check-in information in advance by registering the user U of the terminal 40 or the like. For example, when the terminal 40 is held over the check-in machine 10 and communication with the check-in machine 10 becomes possible, the check-in request unit 41 makes a check-in request to the check-in machine 10. The check-in request unit 41 includes check-in information in the check-in request.

  The route receiving unit 42 is means for receiving display information for performing navigation by the lighting device 30 from the route distributor 20. For example, when the terminal 40 is held over the route distributor 20 and communication with the route distributor 20 becomes possible, the route receiver 42 communicates with the route distributor 20. Thereafter, when display information is transmitted from the route distributor 20, the route receiving unit 42 receives the display information. The route receiving unit 42 outputs the received display information to the device control unit 43 and the lighting time correction unit 45.

  The device control unit 43 is means for controlling lighting of the lighting device 30 based on the display information input from the route receiving unit 42 or the lighting time correction unit 45. The device control unit 43 performs lighting in the color indicated by the lighting color from the time indicated by the scheduled lighting time to the time indicated by the scheduled light-off time with respect to the lighting device 30 whose identifier is indicated in the route of the display information. Send a control signal. The transmission of this control signal is performed by short-range wireless communication, for example. Specifically, it is performed by short-range wireless communication with a communication distance of about several meters to several tens of meters such as Bluetooth. Since the display information may be corrected, the device control unit 43 transmits a control signal to the lighting device 30 immediately before the time indicated in the scheduled lighting time. The device control unit 43 transmits a control signal for starting lighting at the time indicated by the scheduled lighting time (at the timing) to the lighting device 30, and at the time indicated by the scheduled light-off time (at the timing). ) It is good also as transmitting the control signal which complete | finishes lighting.

  The device passage detection unit 44 is passage information acquisition means for acquiring passage information indicating a passage time when the user U has passed through the display position of the lighting device 30 (the position of the lighting device 30 on the route). The device passage detection unit 44 receives a passage detection signal transmitted from the lighting device 30 and detects that it has passed the position of the lighting device 30. Specifically, the detection is performed as follows. The device passage detection unit 44 receives the IMES signal, performs positioning of the terminal 40 based on the signal, and acquires information indicating the latitude and longitude of the terminal 40. The device passage detection unit 44 compares the latitude and longitude, which are positions obtained by positioning, with the latitude and longitude, which are positions of the lighting device 30 on the route. The device passage detection unit 44 detects that the position of the lighting device 30 has passed when it is determined that the difference between the positions (the distance between the positions) is smaller than a preset threshold value. For the detection, the device passage detection unit 44 acquires information indicating the latitude and longitude that are the positions of the lighting devices 30 on the route in advance (for example, receives at the same time as the display information). The device passage detection unit 44 uses the time when the passage is detected as the passage time. When the device passage detection unit 44 acquires the passage information indicating the passage time for each lighting device 30 as described above, the device passage detection unit 44 outputs the passage information of the lighting device 30 to the lighting time correction unit 45.

  Note that the positioning of the terminal 40 by the device passage detection unit 44 may be performed by a method other than the reception of the passage detection signal transmitted from the lighting device 30. The detection of the passage of the position of the lighting device 30 may be performed by a method other than the positioning of the terminal 40 itself. For example, it is good also as setting it as the structure which transmits the beacon for passage detection from the lighting device 30, and detecting the passage of the position of the lighting device 30 based on reception of the said beacon.

  The lighting time correction unit 45 is a function of display information acquisition means that recalculates the lighting time of the lighting device 30 (display by the lighting device 30) based on the passage information acquired by the device passage detection unit 44. When the passage information indicating the passage time for each lighting device 30 is input from the device passage detection unit 44, the lighting time correction unit 45 receives the passage information from the route reception unit 42 as shown in FIG. 4. It adds to the column of the actual passage time of the record corresponding to the lighting device 30 concerned. In addition, the lighting time correction unit 45 moves the current location flag of the display information to a record to which the actual passing time is added. When the actual passage time is input, the lighting time correction unit 45 compares the planned passage time for the lighting device 30 in the display information (scheduled passage time corresponding to the inputted actual passage time) with the inputted actual passage time. When it is determined that they match, the lighting time correction unit 45 does not recalculate the lighting time of the lighting device 30.

  When it is determined that they do not match (for example, the scheduled transit time and the actual transit time where the route of the display information in FIG. 4 is hatched with a diagonal line rising to the right of “104”), the lighting time correction unit 45 Thus, the lighting time of the lighting device 30 is recalculated. First, the lighting time correction unit 45 calculates the difference between the scheduled passage time and the actual passage time for which the above-mentioned mismatch is determined in the display information. Subsequently, the lighting time correction unit 45 converts all the records after the record in which the mismatch is determined in the display information (records related to the position after the position of the record in which the mismatch in the route is determined) with the above difference. to correct. For example, the difference is calculated by subtracting the scheduled passage time from the actual passage time determined to be inconsistent, and thereafter, the difference is added to the scheduled passage time of all records to perform correction. In the example of FIG. 4, in the record whose route is “104”, the actual passage time is 1 second ahead of the scheduled passage time, so 1 second is added to the scheduled passage time of the subsequent records.

  The lighting time correction unit 45 recalculates the scheduled turn-off time based on the actual passage time for the record for which the above mismatch is determined. For example, the lighting time correction unit 45 recalculates and corrects the scheduled turn-off time of each lighting device 30 by adding a preset fixed value (for example, 5 seconds) to the actual passing time. The fixed value may be the same value as the value added to the scheduled transit time in order to calculate the scheduled turn-off time in the route creation unit 21. In addition, the lighting time correction unit 45 performs the planned lighting time and the scheduled light extinction in the same manner as the method by the route creation unit 21 based on the corrected planned passage time for all the records after the record for which the discrepancy is determined. Recalculate and correct the time. The hatched portion of the display information shown in FIG. 4 with the downward slanting diagonal line is a recalculated portion.

  The lighting time correction unit 45 transmits the display information corrected as described above to the route distributor 20 as a correction route approval request. At this time, transmission / reception of information to / from the route distributor 20 is performed by wireless communication such as Bluetooth or wireless LAN as described above. In response to the transmission, the lighting time correction unit 45 receives information on the approval result of the corrected display information from the route distributor 20. When the lighting time correction unit 45 receives the information indicating that the corrected display information is approved from the route distribution machine 20, the lighting time correction unit 45 inputs the corrected display information to the device control unit 43 and replaces the display information before correction. Control based on the corrected display information. When the lighting time correction unit 45 receives information indicating that the corrected display information has been rejected from the route distribution machine 20, the lighting time correction unit 45 does not perform the above processing. That is, the control by the display information before correction is continued. This is because if the lighting device 30 is not lit, the user U can reduce the walking speed, and in this case, there is no need to force correction. The functional configuration of the navigation system 1 has been described above.

  FIG. 5 shows a hardware configuration of the check-in machine 10 and the route distribution machine 20 according to the present embodiment. As shown in FIG. 5, the check-in machine 10 and the route distributor 20 are a central processing unit (CPU) 101, a RAM 102 and a read only memory (ROM) 103 that are main storage devices, and a short distance for performing short distance wireless communication. The wireless communication module 104, the antenna 105, and an auxiliary storage device 106 such as a hard disk are configured as devices including hardware. The functions of the check-in machine 10 and the route distribution machine 20 described above are exhibited by the operation of these components by a program or the like.

  FIG. 6 shows a hardware configuration of the terminal 40 according to the present embodiment. As shown in FIG. 6, the terminal 40 includes hardware such as a CPU 401, a RAM 402 and a ROM 403 that are main storage devices, an operation module 404, a short-range wireless communication module 405, an antenna 406, and a display 407. The functions of the terminal 40 described above are exhibited by the operation of these components by a program or the like. The above is the configuration of the navigation system 1 according to the present embodiment.

  Subsequently, processing executed in the navigation system 1 will be described with reference to the flowcharts of FIGS. 7 and 8. This process is performed when the user U carrying the terminal 40 enters a venue including a navigation area such as a place where a seat is provided.

  In this process, first, the user U holds the terminal 40 over the check-in machine 10, and a check-in process is performed between the terminal 40 and the check-in machine 10 (S01). The check-in request unit 41 of the terminal 40 requests the check-in machine 10 to check in. In the check-in machine 10, the check-in processing unit 11 receives the check-in request and performs the check-in process. The reserved seat information acquired by the check-in processing unit 11 and the information indicating the check-in time are transmitted to the route distributor 20 (S02).

  When the check-in process is completed, the user U moves from the location of the check-in machine 10 to the location of the route distributor 20 installed near the designated seat of the user U, for example. Then, the terminal 40 is held over the route distributor 20 by the user U, and short-distance wireless communication is performed between the terminal 40 and the route distributor 20 (S03). In the route distributor 20, the route creation unit 21 detects that the terminal 40 has reached the position of the route distributor 20 by the start of short-range wireless communication, and the time when the short-range wireless communication is started is determined by the user U. The time when the position of the route distributor 20 is reached is set (S03).

  Subsequently, the route creation unit 21 creates provisional route display information based on the reserved seat information, the check-in time, and the time when the route distributor 20 is reached (S04). The created provisional route display information is output from the route creation unit 21 by the re-creation determination unit 22. Subsequently, the re-creation determination unit 22 compares the display information input from the route creation unit 21 with the stored display information relating to another user U, and the lighting device 30 indicated by the display information. The overlapping of the lighting color and lighting time zone is determined (S05). If it is determined that there is an overlap (there is an overlap in S05), then whether or not the lighting color can be changed by the re-creation determination unit 22 (whether or not the current lighting color is the last priority color) ) Is determined (S06). When it is determined that the lighting color can be changed (the current lighting color is not the last priority color) (S06 can be changed), the re-creation determination unit 22 uses the lighting color of the display information of the provisional route. Is changed to the next priority color (S07), the display information after the change is again determined to be duplicated (S05), and the same processing is performed thereafter.

  If it is determined that the lighting color cannot be changed (the current lighting color is the last priority color) (cannot be changed in S06), the re-creation determination unit 22 notifies the re-creation control unit 23 to that effect. Be notified. Subsequently, the recreation control unit 23 that has received the notification instructs the route creation unit 21 to recreate the route (S08). Subsequently, the route creation unit 21 that has received the instruction calculates a route that is different from the route that has been determined to be duplicated, generates new display information (S04), and the same processing is performed thereafter.

  If it is determined in S05 that there is no duplication (no duplication in S05), then the re-creation judgment unit 22 stores the display information of the provisional route as the display information of the confirmed route and outputs it to the route transmission unit 24 Is done. Subsequently, the route transmission unit 24 transmits the display information of the confirmed route to the terminal 40 (S09). In the terminal 40, the display information transmitted from the route distributor 20 is received by the route receiver 42. The received display information is output from the route receiving unit 42 to the device control unit 43 and the lighting time correction unit 45.

  Subsequently, the lighting of the lighting device 30 is controlled by the device control unit 43 based on the display information (S11 in FIG. 8). In the lighting device 30, the lighting unit 31 performs lighting according to the control. With reference to the lit lighting device 30, the user U can grasp the route to the destination.

  In addition, a passage detection signal is transmitted from the passage detection signal transmitter 32 of the lighting device 30. In the terminal 40, the device passage detection unit 44 receives the passage detection signal and detects that the device has passed the position of the lighting device 30. The time at which the passage is detected is the passage time, and passage information indicating the passage time (actual passage time) of the lighting device 30 is output from the device passage detection unit 44 to the lighting time correction unit 45 (S12). If the device passage detection unit 44 detects the passage of all the lighting devices 30 corresponding to the display information (YES in S13), the user U has arrived at the destination and the processing ends.

  When the passage of all the lighting devices 30 corresponding to the display information is not detected by the device passage detection unit 44 (NO in S13), the lighting time correction unit 45 performs the scheduled passage of the lighting device 30 in the display information. The time and the actual transit time are compared, and it is detected whether there is a difference between them (S14). If it is determined that there is no difference between them (no difference in S14), the lighting time of the lighting device 30 is not recalculated by the lighting time correction unit 45, and the lighting of the lighting device 30 based on the display information by the device control unit 43 is performed. This control is repeated (S15, S11).

  When it is determined that there is a difference between them in S14 (there is a difference in S14), the lighting time correction unit 45 recalculates the lighting time of the lighting device 30. Subsequently, the corrected display information is transmitted to the route distributor 20 as a correction route approval request by the lighting time correction unit 45. In the route distributor 20, the lighting time correction determination unit 25 receives the approval request and determines whether to approve or reject the corrected display information (S16). If the determination is denied (S16 is denied), the lighting time correction determination unit 25 transmits information to that effect to the terminal 40. In the terminal 40, the lighting time correction unit 45 receives the information to that effect, discards the corrected display information, and repeats the lighting control of the lighting device 30 based on the display information before correction by the device control unit 43. Performed (S17, S11).

  When approved by the determination in S16 (approval of S16), the display information corrected by the lighting time correction determination unit 25 is stored in the re-creation determination unit 22 as display information of the confirmed route instead of the display information before correction. In addition, information indicating approval is transmitted to the terminal 40. In the terminal 40, the lighting time correction unit 45 receives the information to that effect, and the corrected display information is input to the device control unit 43. Subsequently, the lighting control of the lighting device 30 based on the corrected display information by the device control unit 43 is performed (S18, S11). The above is the process executed by the navigation system 1.

  As described above, in the present embodiment, the display information of each of the plurality of users U (the plurality of terminals 40) is compared to determine whether route recalculation is necessary. Accordingly, when there is a possibility that the routes of a plurality of users U are confused, the route is recalculated. Thereby, according to this embodiment, the mixing equivalence of the route | root of several users U can be prevented, and appropriate navigation can be performed.

  In the present embodiment, since the navigation is performed by turning on the lighting device 30 embedded in the place where the navigation is performed, the user U walks while looking at the navigation screen of a mobile terminal such as a smartphone (so-called walking smartphone) ) Can be prevented. Therefore, the danger caused by such walking can be prevented.

  Moreover, display information may be created from information indicating the departure place, destination, and departure time of the user U as in the present embodiment. According to this structure, display information can be acquired reliably and this invention can be implemented reliably. However, the navigation system 1 may acquire display information calculated by another device or system.

  Moreover, it is good also as producing display information based on the moving speed for every user U like this embodiment. According to this structure, display information can be made appropriate according to the moving speed of the user U. Further, the moving speed of the user U may be determined not only based on the speed between the check-in machine 10 and the route distributor 20 but also based on the user's attributes and the like. However, it is not always necessary to consider the moving speed for each user U, and the display information may be created on the assumption that the moving speed of the user U is uniform. If the moving speed of the user U is not based on the speed between the check-in machine 10 and the route distribution machine 20, the check-in machine 10 and the route distribution machine 20 are in the same casing. (May be the same device).

  Moreover, it is good also as detecting the passage of the position of the lighting device 30 of the user U like this embodiment, and recalculating the display time of the lighting device 30 (correction | amendment of display information) according to it. According to this structure, display information can be made appropriate according to the movement state of the user U. However, it is not always necessary to recalculate the display time of the lighting device 30, and the display information created first may be used until the end of navigation.

  Moreover, it is good also as making one lighting device 30, such as lighting of multiple colors, perform lighting by a plurality of different display methods as in this embodiment. According to this configuration, it is possible to further prevent confusion between routes of a plurality of users U. However, it is not always necessary to cause one lighting device 30 to perform lighting by a plurality of methods. Further, the plurality of different display methods are not necessarily limited to colors, and may be any method as long as the user U can recognize that the display methods are different.

  In the present embodiment, the navigation target location is a venue with a designated seat such as a theater, a movie theater, or a concert venue. However, any location can be used as long as the lighting device 30 can be installed. It may be a target.
