[Summary of Invention]
The present invention utilizes the fact that a predetermined stop position (station, stop) is set for a vehicle. In other words, the present invention can distinguish the vehicle from other vehicles if it is known at which stop position the vehicle on which the passenger is boarding, so the content corresponding to the vehicle is The principle is that it can be delivered to the passengers of the vehicle. In other words, the present invention is based on the premise that the vehicle stops at a predetermined stop position and the content corresponding to the vehicle can be different for each vehicle. However, the present invention does not prevent a plurality of vehicles having the same corresponding content from being sporadically or accidentally present.

  In the present invention, content refers to information associated with a vehicle. The content according to the present invention is typically data including characters, sounds, images, and the like related to advertisements posted on vehicles. Further, the content may include a hyperlink such as a URL (Uniform Resource Locator) and guide other content (such as an advertiser's website) different from the content. Further, when a plurality of advertisements are posted on a certain vehicle, the content may be information associated with the plurality of advertisements.

[Embodiment]
FIG. 1 is a diagram showing an overall configuration of a content distribution system according to an embodiment of the present invention. The content distribution system 10 of this embodiment is an example in which the present invention is applied to a railway. The content distribution system 10 includes a wireless communication terminal 100, transmitters 201 to 20n, a server device 300, and a content database 400. Server apparatus 300 and wireless communication terminal 100 are connected via network N1 and communicate with each other. The network N1 may be a network in which a plurality of networks (for example, the Internet and a mobile communication network) having different communication protocols are combined.

In the present embodiment, the vehicles C1, C2, C3, and C4 are connected and operated to constitute a train. Here, the train refers to a unit of a unit representing a plurality of connected vehicles. That is, the train shown in FIG. 1 has a four-car train. In addition, the train organization in the present invention may be, for example, a one-car train (single train).
In addition, advertisements are posted on the vehicles C1 to C4, respectively. In the present embodiment, the advertisement is different for each vehicle. The advertisement is assumed to be a printed matter such as a poster or a sticker. The advertisement is for advertising a product or service, but the content is not particularly limited.

  In this embodiment, the stop position of the train on the platform P1 of the station where the train stops is determined in advance, and the train is operated to stop at the stop position. In this case, each vehicle constituting the train also stops at a predetermined stop position. That is, the stop position is a position where the vehicle stops. In addition, when distinguishing a certain train and another train, a stop position may be grasped in a wider range (that is, station unit) than a position where the vehicle stops.

  The transmitters 201 to 20n are installed on the platform P1. Here, the value of n corresponds to the train organization. The value of n is, for example, at least 4 or more if the train operates in a 4-car train, but is assumed to be 4 (that is, the same number as the vehicle) in this embodiment. The transmitters 201 to 204 are installed so as to correspond to the stop positions of the vehicles. For example, the transmitter 201 corresponding to the vehicle C1 is installed at a position closer to the vehicle C1 stopped at a predetermined stop position than the other transmitters 202 to 204. Similarly, when the train stops at a predetermined stop position, the transmitter nearest to the vehicle C2 is the transmitter 202. The transmitters 201 to 204 may be installed at any position such as a pillar, a floor surface, or a so-called platform door of the platform P1, but are preferably installed as close as possible to each stopped vehicle.

  Each of the transmitters 201 to 204 repeatedly transmits a signal including position information indicating the nearest stop position. The position information here is data that can specify the station, the platform, and the stop position, and is an example of the stop position information according to the present invention. As the transmitters 201 to 204, for example, a base station that forms a femtocell, a transmitter that complies with other short-range wireless communication schemes with which the wireless communication terminal 100 can communicate, a wireless LAN (Local Area Network) access point, and the like Can be used. In addition, the transmitters 201 to 204 may use a so-called acoustic watermark technique to transmit the position information by superimposing (that is, modulating) the position information on the sound. An example of acoustic watermarking is acoustic OFDM (Orthogonal Frequency-Division Multiplexing).

  FIG. 2 is a diagram illustrating a data structure of position information transmitted from the transmitters 201 to 204. As shown in FIG. 2, the position information of the present embodiment is data obtained by connecting a station ID and a stop position ID. The station ID is data corresponding to the station name, but may be replaced with an appropriate number. Stop position ID is data showing the position which divided the platform in some ranges with respect to the moving direction of a train, and represents the stop position mentioned above. The stop position ID is typically a number in the case of “first car” and “second car” assigned to each vehicle.

  The server device 300 is a server device that acquires content from the content database 400 and distributes the content to the wireless communication terminal 100. The content database 400 is a database (hereinafter referred to as “DB”) that stores a plurality of contents. The content DB 400 may be a storage device independent of the server device 300, or may be configured as a part of storage means (for example, a storage unit 320 described later) provided in the server device 300.

The storage unit 320 includes storage means (such as a hard disk) corresponding to an auxiliary storage device, and stores data used by the control unit 310. The first communication unit 330 is a communication interface for connecting to the network N1, and transmits and receives data to and from the wireless communication terminal 100. On the other hand, the second communication unit 340 is a communication interface for connecting to the content DB 400 and transmitting / receiving data.

  The content DB 400 stores content in association with vehicle information. Here, the content is information associated with the advertisement posted on the vehicle. Here, the vehicle information refers to information representing a vehicle, and is information for distinguishing between a vehicle on which a certain advertisement is placed and a vehicle on which another advertisement is placed. Therefore, the vehicle information is information that can distinguish each vehicle (that is, what number of eyes) when a different advertisement is posted for each vehicle of a certain train. On the other hand, when a common advertisement is posted on each vehicle of a certain train, the vehicle information only needs to be information that can distinguish the train (not each vehicle). Moreover, time information (information for specifying the time) and information for specifying the station corresponding to the stop position or its route may be added to the vehicle information as necessary.

The wireless communication terminal 100 is possessed by a user who uses a train, and is, for example, a mobile phone or a smartphone. The wireless communication terminal 100 receives and outputs the content stored in the content database 400 via the network N1 and the server device 300.

  FIG. 4 is a block diagram illustrating a hardware configuration of the wireless communication terminal 100. As illustrated in FIG. 4, the wireless communication terminal 100 includes a control unit 110, a storage unit 120, a first communication unit 130, a second communication unit 140, a positioning unit 150, an acceleration sensor 160, and a display unit 170. A voice input / output unit 180 and an operation unit 190.

  The control unit 110 includes an arithmetic processing unit and a memory, and controls the operation of each unit of the wireless communication terminal 100 by executing a program stored in advance. The program executed by the control unit 110 reproduces (that is, outputs) an application program (hereinafter referred to as “vehicle identification application”) for identifying a vehicle on which the user is boarded (hereinafter referred to as “boarding vehicle”). ) Application program (hereinafter referred to as “playback application”). The control unit 110 has a clock function and can recognize the time. The storage unit 120 includes storage means (flash memory or the like) corresponding to an auxiliary storage device, and stores data used by the control unit 110. In this embodiment, the memory | storage part 120 has memorize | stored timetable data and route map data other than the program corresponded to the vehicle specific application mentioned above and the reproduction | regeneration application.

  The first communication unit 130 is a communication interface for connecting to the network N1, and transmits and receives data to and from the server device 300. The second communication unit 140 is a communication interface for receiving position information transmitted from the transmitters 201 to 204. The second communication unit 140 is preferably configured to detect the strength (electric field strength) of signals transmitted from the transmitters 201 to 204.

  The positioning unit 150 is a module that acquires positioning information by a predetermined positioning method. Here, the positioning information refers to information indicating the position of the wireless communication terminal 100, for example, data representing the position by a combination of latitude and longitude. The positioning information is an example of terminal location information according to the present invention. The positioning method used by the positioning unit 150 is, for example, a GPS (Global Positioning System) method, but any method can be used as long as information that can be identified with the position of the wireless communication terminal 100 is obtained. Good. The positioning unit 150 supplies the acquired position information to the control unit 110.

  The acceleration sensor 160 detects acceleration acting on the wireless communication terminal 100. The acceleration sensor 160 is preferably a so-called triaxial acceleration sensor that can detect accelerations in three directions orthogonal to each other. The acceleration sensor 160 supplies acceleration data representing the detected acceleration to the control unit 110.

  The display unit 170 includes a display medium such as a liquid crystal display and a driving unit thereof, and displays an image corresponding to the content when the content including the image is output. The audio input / output unit 180 includes a microphone and a speaker, and acquires and reproduces audio. The audio input / output unit 180 reproduces audio corresponding to the content when content including audio is output. The voice input / output unit 180 generates voice data based on the acquired voice and supplies the voice data to the control unit 110. The operation unit 190 includes input means for accepting a user operation, and supplies operation data corresponding to the accepted operation to the control unit 110. The operation unit 190 may be a keypad (or a keyboard), or may be a touch screen provided on the display medium of the display unit 170.

  As described above, the storage unit 120 stores timetable data and route map data. The timetable data is data describing the departure and arrival times of trains for each station. Route map data is data describing the position information of routes operated by a train for each route. That is, the route map data is data describing which route is operating at which position. The route map data is data representing the position operated by each route by a combination of latitude and longitude. The train operates on a predetermined route according to a time preset by timetable data. The structure of these data is as follows.

  FIG. 5 is a diagram illustrating a data structure of timetable data. As shown in FIG. 5, the timetable data is data in which a station ID, a route ID, a train ID, and a departure / arrival time are described in association with each other. Station ID is the same data as what is contained in the positional information which the transmitters 201-204 transmit. The route ID is a character string or number that identifies the route on which the train operates, and the train ID is a character string or number that identifies the train (not the vehicle). The departure / arrival time is a numeric string representing the time when the train arrives or departs. By referring to such timetable data, the wireless communication terminal 100 can identify which train on which route and at which station. The departure / arrival time here is sufficient if at least one of the arrival time and the departure time is described, and both need not be described.

  FIG. 6 is a diagram illustrating a data structure of route map data. The route map data is data in which a route ID and position information are associated with each other as shown in FIG. The route ID is data similar to that included in the timetable data described above. The position information is data describing the latitude and longitude of a plurality of positions on the route. By referring to such route map data, the wireless communication terminal 100 can specify the route when the train on which the user is riding is traveling.

  FIG. 7 is a schematic map for explaining routes and positions represented by route map data. The example of FIG. 7 shows a case where there are a route A and a route B that are operated by a train, and these intersect (overlap) at a position P1. Here, it is assumed that there is a station at the position P1. That is, the route A and the route B are routes including the same stop station, and are routes including the same stop position. When the user is on a train and the positioning information acquired by the user terminal indicates the position P1, the wireless communication terminal 100 specifies whether the route of the train is the route A or the route B. I can't. That is, when the train on which the user is boarding is stopped at the station, the wireless communication terminal 100 may erroneously recognize the route of the train. However, if the train departs and positioning information of other positions different from the position P1 (for example, positions P2 and P3) can be acquired, the wireless communication terminal 100 can specify the train route.

  Note that the positioning information acquired by the wireless communication terminal 100 does not always accurately indicate the position of the wireless communication terminal 100, and may include an error. Therefore, when the route is specified by the positioning information, the wireless communication terminal 100 may make it difficult for erroneous recognition to occur by performing positioning a plurality of times. Moreover, it can be said that the difference between the positions of the route A and the route B is generally smaller as the position is closer to the station (that is, the intersecting position). Therefore, when the route is specified by the positioning information, the wireless communication terminal 100 may perform positioning after a predetermined time (1 to several minutes) has elapsed since the train departed.

  The wireless communication terminal 100 uses such timetable data and route map data when executing the vehicle identification application. Note that the timetable data and route map data may be data constituting a part of the vehicle identification application. The timing at which the wireless communication terminal 100 executes the vehicle identification application may be determined according to a user operation, or may be the timing at which position information transmitted by the transmitters 201 to 204 is detected. In the case of the former example, the user performs an operation of instructing execution of the vehicle identification application at the timing of arrival at the station or the timing of getting on the vehicle.

  FIG. 8 is a functional block diagram showing a functional configuration of the vehicle identification application. The control unit 110 of the wireless communication terminal 100 executes the vehicle identification application, thereby recognizing the recognition unit 111, the identification unit 112, the transmission unit 113, the reception unit 114, the output unit 115, the acquisition unit 116, and the detection unit 117 illustrated in FIG. A function equivalent to is realized. Note that the functions corresponding to the acquisition unit 116 and the detection unit 117 are not essential functions.

  The recognition unit 111 recognizes position information (that is, stop position information) transmitted from the transmitters 201 to 204. When the recognizing unit 111 acquires the signal transmitted from the transmitters 201 to 204 via the second communication unit 140, the recognizing unit 111 recognizes this and obtains data corresponding to the position information. That is, the recognition unit 111 functions as a recognition unit according to the present invention by cooperating with the second communication unit 140. When the signal can be acquired from the plurality of transmitters 201 to 204, the recognition unit 111 compares the strength of each signal, and the signal having the highest strength is a signal transmitted from the nearest transmitter. I reckon.

  The specifying unit 112 functions as specifying means according to the present invention. The identification unit 112 identifies the boarding vehicle based on the position information recognized by the recognition unit 111. The specifying unit 112 can refer to timetable data and route map data in order to specify the boarding vehicle. More specifically, the specifying unit 112 specifies a station ID from the position information recognized by the recognizing unit 111, and specifies a train to / from the station when specifying a vehicle based on timetable data. In addition, when there are a plurality of trains having the same departure and arrival times at the same station, the specifying unit 112 uniquely identifies the train by referring to the route map data and further specifying the route. In this case, the specifying unit 112 can specify the train not after the train is stopped at the predetermined stop position but after the departure. When the boarding vehicle is specified in this way, the specifying unit 112 generates vehicle information representing the boarding vehicle. The vehicle information is data obtained by combining the train ID and the stop position ID, and represents which vehicle of which train the user is on.

The transmission unit 113 transmits the vehicle information generated by the specifying unit 112 to the server device 300 via the first communication unit 130. That is, the transmission unit 113 performs control necessary for the first communication unit 130 to transmit vehicle information. The receiving unit 114 receives the content transmitted from the server device 300 according to the vehicle information transmitted by the transmitting unit 113 via the first communication unit 130. That is, the receiving unit 114 performs control necessary for the first communication unit 130 to receive content.
That is, in this embodiment, the transmission means according to the present invention is realized by the cooperation of the transmission unit 113 and the first communication unit 130. Similarly, the receiving means according to the present invention is realized by the cooperation of the receiving unit 114 and the first communication unit 130.

  The output unit 115 functions as output means according to the present invention. The output unit 115 outputs the content received by the receiving unit 114 to each unit corresponding to the content. The output unit 115 causes the display unit 170 to display an image when the content includes an image, and causes the audio input / output unit 180 to reproduce the audio when the content includes audio.

  The acquisition unit 116 acquires positioning information (that is, terminal position information) via the positioning unit 150. That is, the acquisition unit 116 functions as an acquisition unit according to the present invention by cooperating with the positioning unit 150. The acquisition unit 116 acquires positioning information in response to an instruction from the specifying unit 112. In a case where the boarding vehicle is stopped at a station where the boarding vehicle is present, the specifying unit 112 acquires positioning information to the acquiring unit 116 after a predetermined time has elapsed when there are a plurality of trains having the same arrival and departure times at the station. Instruct. The acquiring unit 116 acquires positioning information in response to this instruction and supplies the positioning information to the specifying unit 112.

  The detection unit 117 acquires acceleration data via the acceleration sensor 160. That is, the detection unit 117 performs control necessary for the acceleration sensor 160 to supply acceleration data. The detection unit 117 functions as a detection unit according to the present invention by cooperating with the acceleration sensor 160. The detection unit 117 can acquire acceleration data in response to an instruction from the reception unit 114.

  The receiving unit 114 suspends the control for receiving the content when a state in which wireless communication with the network N1 cannot be performed (a so-called out-of-service state) continues for a predetermined time, such as when the train is a subway. Such interruption is performed to reduce power consumption. The receiving unit 114 determines whether or not the acceleration represented by the acceleration data has changed in a predetermined pattern as a trigger for resuming the control for receiving the content. Here, the predetermined pattern refers to a pattern that is characteristic when an out-of-service state is removed. Such a pattern is, for example, an acceleration pattern when the train decelerates (or stops) by applying a brake, and is hereinafter referred to as a “stop pattern”. The train generally decelerates when it approaches the station. At this time, if a base station for connecting to the network N1 is provided at the station, the wireless communication terminal 100 becomes capable of wireless communication as it approaches the station. When detecting the stop pattern described above, the detection unit 117 notifies the reception unit 114 to that effect. The receiving unit 114 resumes control for receiving the content in response to this notification.

  The configuration of the content distribution system 10 is as described above. Under this configuration, the wireless communication terminal 100 executes the vehicle identification application, identifies the user's boarding vehicle, and transmits vehicle information to the server device 300. When receiving the vehicle information, the server device 300 acquires content stored in association with the vehicle information from the content DB 400. When the server device 300 acquires the content, the server device 300 distributes the content to the wireless communication terminal 100. When receiving the content, the wireless communication terminal 100 executes the playback application and prompts the user to play the content.

  FIG. 9 is a flowchart illustrating a process executed by the vehicle identification application by the wireless communication terminal 100. As shown in FIG. 9, the control unit 110 of the wireless communication terminal 100 first determines whether or not the position information transmitted from the transmitters 201 to 204 has been recognized (step S1). When the position information cannot be recognized, the control unit 110 determines whether or not the period during which the position information cannot be recognized continues for a predetermined time (step S11), and attempts to recognize the position information until the predetermined time is reached. The process is repeated (steps S1 and S11). When the period during which position information cannot be recognized continues for a predetermined time, control unit 110 determines that the user has not boarded the vehicle (step S12), and ends the vehicle specifying application.

  When the position information can be recognized, the control unit 110 determines whether or not the user has boarded (step S2). This determination is made by determining whether or not the vehicle has started. Specifically, control unit 110 detects that the vehicle has started when it detects a pattern of acceleration at the time of departure of the vehicle (a pattern of acceleration from a stopped state; hereinafter referred to as “departure pattern”), and the user gets on board It is considered that it did. In addition, when the departure pattern is not detected, the control unit 110 determines whether or not the period in which the departure pattern is not detected continues for a predetermined time (for example, several minutes) (step S11), and the predetermined time continues. Until then, the processes in and after step S1 are repeated. In addition, the control part 110 memorize | stores each positional information, when positional information can be recognized twice or more in the process of step S1 performed multiple times. If the departure pattern is not detected for a predetermined time, the control unit 110 determines that the user has not boarded the vehicle (step S12), and ends the vehicle specifying application, as in the case where the position information cannot be recognized.

  When detecting the departure pattern, control unit 110 extracts specific position information from the recognized position information (step S3). At this time, when a plurality of pieces of position information are recognized, the control unit 110 extracts the position information recognized immediately before detecting the departure pattern. The user may be walking on the platform before boarding or moving between vehicles before departure. In such a case, the wireless communication terminal 100 may recognize position information at various positions. Therefore, by performing such extraction, the control unit 110 can more accurately identify the user's boarding vehicle. In addition, when there are a plurality of position information recognized immediately before the departure pattern is detected, the control unit 110 extracts the position information detected by the highest intensity signal. Note that the control unit 110 can omit the process of step S3 if there is only one recognized position information.

  When the position information is extracted, the control unit 110 specifies the user's boarding vehicle based on the extracted position information (step S4). The method for specifying the boarding vehicle is as described with reference to FIGS. When the boarding vehicle is specified, control unit 110 transmits vehicle information representing the specified boarding vehicle to server device 300 (step S5).

  Thereafter, the control unit 110 determines whether or not content has been received (step S6). When the content is received, the control unit 110 activates the playback application (step S7). At this time, for example, the control unit 110 causes the display unit 170 to display a message such as “Do you want to view information related to the advertisement posted on this vehicle?” In advance, and play after obtaining the user's permission. You may launch the app. In addition, when the user views the content or actually purchases a product or the like through so-called online shopping, the control unit 110 may notify the server device 300 to that effect. The server apparatus 300 may collect the notifications and collect the advertisement price from the advertiser.

  On the other hand, when the content cannot be received, the control unit 110 attempts to receive the content until a predetermined time has elapsed (step S8). When the period during which content cannot be received continues for a predetermined time, control unit 110 temporarily suspends the process for receiving content (step S9). And the control part 110 restarts the process after step S8, when the predetermined conditions for restart are satisfy | filled (namely, when the stop pattern mentioned above is detected).

  As described above, according to the content distribution system 10, it is possible to distribute content related to a vehicle to passengers without providing special equipment in the vehicle. Thereby, the user can obtain more information about the advertisement posted on the vehicle. Further, the transmitters 201 to 20n do not need to change the information to be transmitted according to the train or time of arrival, and need only continue to transmit the same information.

  In addition, according to the content distribution system 10, since the position of the user can be specified in units of vehicles, not in units of trains, even if different advertisements are posted for each vehicle, content corresponding to each vehicle Can be delivered. Furthermore, according to the content distribution system 10, even if a different advertisement is posted for each train or for each route, content corresponding to each vehicle can be distributed.

In the present invention, the vehicle is not limited to a train. The vehicle according to the present invention may be any vehicle as long as it operates while stopping at a predetermined stop position, and may be a bus or a tram, for example.

(Modification 2)
The present invention does not preclude implementation when the same advertisement is placed on a train on the same route. In such a case, the present invention can be implemented without using the above-described route ID. Similarly, the present invention does not preclude implementation when the same advertisement is placed on each train vehicle. In such a case, the present invention can be implemented without using the stop position ID described above.

(Modification 3)
In the present invention, some methods for determining whether to resume control for receiving content do not use acceleration. For example, whether or not the wireless communication terminal according to the present invention restarts the control depending on whether or not wireless communication with the server device is possible (that is, whether or not a signal having a strength necessary for communication can be received). It may be judged.

(Modification 4)
In the present invention, a method for determining that the user has not boarded the vehicle (see step S12 in FIG. 9) uses a so-called pedometer function (a function for measuring the number of steps of the user). For example, when the wireless communication terminal according to the present invention has the function of a pedometer, when the user walks more than a predetermined number of steps since the position information was last recognized, the user did not get on the vehicle. May be.

(Modification 5)
The recognition means according to the present invention may not use communication. For example, when the wireless communication terminal according to the present invention has a photographing function (that is, a digital camera), the recognition means is realized by reading an image (bar code, two-dimensional code, etc.) obtained by encoding stop position information. May be.

(Modification 6)
In the present invention, when there are a plurality of routes including the same stop position, the determination of the route may be performed by accepting a user operation without being performed by the wireless communication terminal itself. For example, in the case illustrated in FIG. 7, the wireless communication terminal displays a screen for confirming to the user, “Which route is boarding route A or route B?” And accepts the user's operation. May be.

(Modification 7)
The present invention is grasped not only as a wireless communication terminal and a content distribution system including the same, but also as a method for realizing them and a program for causing a computer to realize the functions shown in FIG. Such a program may be provided in the form of a recording medium such as an optical disk storing the program, or may be provided in the form of being downloaded to a computer via a network such as the Internet, and installed and made available. Is something that can be done.
