Then, each of the detection devices 30-1 to 30-n transmits the generated congestion status information to the server 20. Each of the detection devices 30-1 to 30-n recognizes the congestion status in the vehicle and sends the congestion status information to the server 20 every time the train of the vehicle on which the detection device is installed leaves at least each station. It is desirable to send.

  2 is a block diagram showing an example of the configuration of each device constituting the image display system 100 shown in FIG. 1, wherein (a) is a block diagram showing the configuration of the server 20, and (b) is a mobile terminal 10-. 1 is a block diagram showing a configuration of 1. FIG.

  Referring to FIG. 2A, the server 20 includes a database 21, a communication unit 22, and a control unit 23.

  The database 21 stores each of the station name information of a plurality of stations in association with each of a plurality of station IDs that identify each of the plurality of stations. Further, the database 21 includes a vehicle-by-vehicle congestion state information table, an identifier information table, and a timetable information table.

  3 is a diagram illustrating an example of a configuration of a table included in the database 21 illustrated in FIG. 2, (a) is a diagram illustrating a configuration of a congestion status information table for each vehicle, and (b) is a configuration of an identifier information table. FIG. 8C is a diagram showing a configuration of a timetable information table.

  The congestion status information table for each vehicle is generated for each of a plurality of train IDs. As shown in FIG. 3A, in the congestion status information table for each vehicle, the vehicle ID is associated with the congestion rate of the vehicle identified by the vehicle ID.

  The identifier information table is generated for each of a plurality of station IDs. As shown in FIG. 3B, in the identifier information table, the vehicle ID, the identifier information, and the exit information indicating the position of the ticket gate or stairs at the station identified by the station ID are associated with each other.

  In the identifier information table, the exit information has a value of “0” or “1”, and “1” indicates the position of the ticket gate or the stairs. Therefore, in the example shown in FIG. 3B, the vehicle identified by the vehicle ID “2” is the vehicle closest to the ticket gate or the stairs.

  In addition, it is assumed that each of the plurality of identifiers indicated by each of the plurality of identifier information in the identifier information table is displayed at the entrance of each of the plurality of vehicles on the platform of the station. Each of the plurality of identifiers is different in shape, pattern, and the like, for example.

  As shown in FIG. 3C, in the timetable information table, a train ID is associated with a plurality of station IDs for identifying stations at which the train identified by the train ID stops and departure times of the stations. ing. In the example shown in FIG. 3C, the train with the train ID “001” departs from the station identified by the station ID “0005” at “12:45”, and then at the station ID “0006”. The identified station will depart at “12:50”.

  Referring to FIG. 2A again, the communication unit 22 has a wireless communication function. The communication unit 22 receives the congestion status information transmitted from each of the detection devices 30-1 to 30-n and outputs the received congestion status information to the control unit 23. In addition, the communication unit 22 receives the selection information transmitted from each of the mobile terminals 10-1 to 10-n and outputs the received selection information to the control unit 23. Note that the selection information includes boarding station name information that is station name information of a boarding station, getting-off station name information that is station name information of a station to get off, and time information. In addition, the communication unit 22 receives the identifier information output from the control unit 23 and transmits the received identifier information to the portable terminal that is the transmission source of the selection information.

  The control unit 23 receives the congestion status information output from the communication unit 22. And the control part 23 updates the congestion rate of the congestion condition information table classified by vehicle based on the received congestion condition information. Specifically, the control unit 23 sets the congestion rate corresponding to the vehicle ID added to the congestion status information in the congestion status information table for each train ID added to the received congestion status information. Update to the value indicated by the information. Further, the control unit 23 receives the selection information output from the communication unit 22. Then, the control unit 23 extracts at least one identifier information from the identifier information table based on the boarding station name information, the getting-off station name information, the time information, and the predetermined selection condition included in the received selection information. Then, the control unit 23 outputs the extracted identifier information to the communication unit 22. Here, the detail of the operation | movement which the control part 23 extracts identifier information is demonstrated.

  FIG. 4 is a flowchart for explaining an operation in which the control unit 23 of the server 20 shown in FIG. 2 extracts identifier information.

  The control unit 23 refers to the timetable information table, and the departure time of the station ID corresponding to the boarding station name information is later than the time indicated by the time information, and the station ID corresponding to the getting-off station name information is included. Among the train IDs in the row, the train ID having the earliest departure time of the station ID corresponding to the boarding station name information is specified (step S1). For example, when the timetable information table has the contents shown in FIG. 3C, the station ID corresponding to the boarding station name information is “0005”, the time indicated by the time information is “12:46” If the station ID corresponding to the station name information is “0007”, the train ID “002” is specified. This specifying method is an example, and the train ID may be specified by another method.

  Next, the control unit 23 selects a vehicle ID corresponding to the exit information value “1” as a selected vehicle ID from the identifier information table of the station ID corresponding to the getting-off station name information (step S2). For example, when the station ID identifier information table corresponding to the getting-off station name information has the contents shown in FIG. 3B, the vehicle ID “2” is selected as the selected vehicle ID. In the following description, the identifier information table of the station ID corresponding to the getting-off station name information is simply referred to as an identifier information table.

  Next, the control unit 23 extracts the congestion rate corresponding to the selected vehicle ID from the congestion status information table for each train ID identified in step S1 (step S3). For example, when the congestion status information table for each train ID identified in step S1 has the contents shown in FIG. 3A and the selected vehicle ID is “2”, the control unit 23 sets the congestion rate “65”. Will be extracted.

  And the control part 23 determines whether the extracted congestion rate is more than a predetermined threshold value (step S4).

  As a result of the determination in step S4, if the extracted congestion rate is greater than or equal to a predetermined threshold, the control unit 23 determines whether or not all vehicle IDs have been selected as selected vehicle IDs in the identifier information table (step S5). ).

  As a result of the determination in step S5, when all the vehicle IDs have not been selected as the selected vehicle IDs in the identifier information table, the control unit 23 displays the exit information of the vehicle IDs not selected as the selected vehicle ID in the identifier information table. A vehicle ID having a value closest to the vehicle ID corresponding to 1 is selected as a new selected vehicle ID (step S6). For example, when the identifier information table has the contents shown in FIG. 3B and the selected vehicle ID is “2”, the control unit 23 sets the vehicle ID “1” and the vehicle ID “3” as the new selected vehicle ID. Will be selected as.

  And it changes to operation | movement of step S3.

  On the other hand, as a result of the determination in step S5, when all the vehicle IDs have been selected as the selected vehicle IDs in the identifier information table, the control unit 23 determines from the identifier information table that the identifier corresponding to the exit information value “1”. Information is extracted (step S7). For example, when the identifier information table has the contents shown in FIG. 3B, the control unit 23 extracts the identifier information b.

  If the extracted congestion rate is smaller than a predetermined threshold as a result of the determination in step S4, the control unit 23 extracts identifier information corresponding to the selected vehicle ID from the identifier information table (step S8). .

  In addition, when two vehicle ID is selected as selection vehicle ID in step S6, two congestion rates are extracted in step S3. In this case, if the two extracted congestion rates are both smaller than a predetermined threshold value, two identifier information corresponding to each of the two selected vehicle IDs may be extracted. Alternatively, any one of the two selected vehicle IDs may be selected by some method, and only the identifier information corresponding to the selected selected vehicle ID may be extracted.

  Further, as a result of the determination in step S5, when all the vehicle IDs have been selected as the selected vehicle ID in the identifier information table, the threshold value may be increased by a predetermined width and the operations in steps S2 to S6 may be repeated again. .

  The position measuring unit 13 of the mobile terminal 10-1 detects the floor number of the current position of the mobile terminal 10-1 (step S41). Then, the position measuring unit 13 outputs floor information indicating the floor to the control unit 17. Here, the position measurement unit 13 not only measures the current position of the mobile terminal 10-1 by receiving a GPS signal, but also receives a signal from an access point of a wireless LAN (Local Area Network). The current position of the mobile terminal 10-1 may be measured with

  Next, the input unit 14 receives an input of the number of floors from which the operator gets off the elevator from the operator of the mobile terminal 10-1 (step S42). Then, the input unit 14 outputs floor information indicating the received floor number to the control unit 17.

  Next, the control part 17 receives the floor information output from the position measurement part 13 as boarding floor information, and receives the floor information output from the input part 14 as alighting floor information.

  Next, the control unit 17 generates selection information including the received boarding floor information and getting-off floor information, and outputs the generated selection information to the communication unit 15.

  The communication unit 15 that has received the selection information output from the control unit 17 transmits the received selection information to the server 20 (step S43).

  The communication unit 22 of the server 20 receives the selection information transmitted from the mobile terminal 10-1 and outputs the received selection information to the control unit 23.

  The control unit 23 that has received the selection information output from the communication unit 22 has at least the congestion status information table for each elevator included in the database 21 based on the boarding floor name information and the getting-off floor name included in the received selection information. One elevator ID is selected (step S44). For example, when the elevator congestion status information table has the contents shown in FIG. 7, it is assumed that the number of floors indicated by the boarding floor name information is 4 and the floor number indicated by the getting-off floor name information is 1. In this case, elevators with elevator IDs “1” and “2” can be selected, but the congestion rate corresponding to elevator ID “2” is lower than the congestion rate corresponding to elevator ID “1”. Therefore, the control unit 23 selects the elevator ID “2”.

  Next, the control unit 23 extracts identifier information corresponding to the elevator ID selected in step S44 from the congestion status information table by elevator (step S45). Then, the control unit 23 outputs the extracted identifier information to the communication unit 22.

  The communication unit 22 that has received the identifier information output from the control unit 23 transmits the received identifier information to the mobile terminal 10-1 (step S46).

  Subsequent operations in steps S47 to S50 are the same as those in steps S26 to S29 described with reference to FIG.
