Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of a content information distribution system according to the present embodiment. The content information distribution system shown in FIG. 1 has a train 10 and a ground server group 30.

  The train 10 is an n-car train in which n cars (n is a natural number) 11-1 to 11-n are connected. The vehicles 11-1 to 11-n include train information management devices 12-1 to 12-n and information distribution terminals 13-1 to 13-n.

  Train information management devices 12-1 to 12-n are connected between adjacent vehicles, and the train information management devices 12-1 to 12-n constitute a train information management system. Here, the connection interface of the train information management devices 12-1 to 12-n may be, for example, a LAN (Ethernet (registered trademark)), but is not limited thereto.

  Note that the information distribution terminals 13-1 to 13-n are not connected between adjacent vehicles, and the information distribution terminals 13-1 to 13-n of each vehicle are train information management devices 12-1 to 12-1 of each vehicle. 12-n. The information distribution terminals 13-1 to 13-n are installed in the vehicles 11-1 to 11-n and perform short-range wireless communication with the mobile terminal 20a on the vehicle located in the communicable range. The train information distributed by the information distribution terminals 13-1 to 13-n includes information from the train information management devices 12-1 to 12-n. That is, information that is completed within the train 10 is distributed from the information distribution terminals 13-1 to 13-n to the mobile terminal 20a on the vehicle. Examples of the mobile terminal 20a on the vehicle include a mobile phone, a smartphone, a game machine having a communication function, and a dedicated terminal for the content information distribution system.

  The ground server group 30 includes a content server 31 connected to the Internet 41, a train information management server 32 that communicates with the train information management device 12-n, an operation guide server 33, and an operation management system server 34.

  The content server 31 is connected to the train information management server 32, the operation guide server 33, and the operation management system server 34.

  The train information management server 32 collects and manages the train information of each train acquired through direct communication with the train information management device 12-n. The operation guidance server 33 manages information such as the status of the operation postponement input from the outside and the expected recovery time of the route. Information that cannot be automatically generated is input to the operation management system server 34 from the outside.

  “Train information” refers to information relating to the train vehicle on which the user is riding. Therefore, even within the same train, the train information is different for each vehicle. The train information includes, for example, “train number”, “train number”, “train type”, “travel position”, “state of each vehicle (for example, room temperature and congestion degree)”, and the like. “Composition number” is a number for identifying the composition of the train.

  “Boarding train information” refers to information relating to the organization of the train on which the user is riding. Therefore, if it is in the same organization, boarding train information is the same even if vehicles are different.

  “Train information” includes train position information, train operation information, train current information, and train command information. The “train position information” includes the distance from the first station, the train route, and the like. “Train operation information” includes stop station information, estimated arrival time, and the like. “Train current information” includes arrival time, number of passengers, and the like. The “train command information” includes a door opening / closing command, a stop command, and the like.

  The operation of the content information distribution system shown in FIG. 1 will be described below with reference to FIGS.

  Train content information provided by the content information distribution system is roughly classified into operation content information and advertisement / guide content information. “Operating content information” refers to content information related to train operations such as next station guidance and transfer guidance. Train information is necessary for the operation content information. “Advertisement / guidance content information” refers to, for example, advertisement information that advertises products and the like, and content information that expresses guidance information such as news, weather forecasts, stock price information, and the like as moving images or still images.

  FIG. 2 is a sequence diagram showing operations of the information distribution terminal 13-1 and the mobile terminal 20a on the vehicle until the on-board information is displayed on the mobile terminal 20a on the vehicle when getting on. FIG. 2 shows an example in which a user who has a mobile terminal 20a on the vehicle gets on the vehicle 11-1.

  “Vehicle information” refers to information that is distributed from an information distribution terminal in a vehicle to a portable terminal and displayed on the portable terminal when the user gets on. As on-board information, for example, “next station arrival guidance”, “in-vehicle situation (such as boarding rate)”, “get-off alarm”, “room temperature (in the vehicle)”, “transfer guidance”, “transfer train guidance” And “stop station guide”.

  First, the information distribution terminal 13-1 generates a connection confirmation message to be distributed to the mobile terminal 20a on the vehicle (step S1).

  When the user gets on the vehicle 11-1, the portable terminal 20a on the vehicle is generated by the information distribution terminal 13-1 by radio waves of short-range wireless communication (for example, Bluetooth (registered trademark) or Wi-Fi (registered trademark)). The received connection confirmation message is automatically received (step S2).

  When the user activates the application of the content information distribution system by operating the mobile terminal 20a on the car, a connection confirmation message is displayed on the screen of the mobile terminal 20a on the car (step S3). When the user operates the application display screen of the connection confirmation message, a connection confirmation response is made from the mobile terminal 20a on the vehicle to the information distribution terminal 13-1 (step S4), and the information distribution terminal 13-1 performs a connection process. (Step S5), the mobile terminal 20a on the vehicle and the information distribution terminal 13-1 start communication.

  One or more information distribution terminals 13-1 to 13-n are mounted on each of the vehicles 11-1 to 11-n in consideration of the communicable range of short-range wireless communication. Then, in the vicinity of the boundary between vehicles adjacent to each other (in the vicinity of the boundary of the communicable range of the information distribution terminal), the information distribution terminal of the vehicle on which the user is actually on (the portable terminal is present) and the information distribution of the adjacent vehicle In some cases, short distance wireless communication radio waves are received from both terminals, and connection confirmation messages from a plurality of information distribution terminals are received.

  In the present invention, a train number is added to the connection confirmation message, and when the user operates the connection confirmation message display screen, the train number is selected to specify the vehicle. With such a configuration, it is possible to identify a vehicle on board even in the vicinity of the boundary between adjacent vehicles.

  When the mobile terminal 20a on the car and the information distribution terminal 13-1 start communication, the mobile terminal 20a on the car periodically acquires train information from the information distribution terminal 13-1 by short-range wireless communication. (Step S6). Here, the information sent collectively from the information distribution terminal 13-1 may be the train information data itself, or a path to the train information stored as a file in the information distribution terminal 13-1. Also good.

  In addition, the information distribution terminal 13-1 acquires a formation number, a train number, etc. from the train information management apparatus 12-1. The travel position of the vehicle is also acquired from the train information management device 12-1. The mobile terminal 20a on the vehicle exists in the vehicle 11-1 by the composition number and the train number, and the position of the mobile terminal 20a on the vehicle is grasped by the traveling position of the vehicle 11-1. As described above, when the vehicle and the vehicle position are specified, if the GPS function can be switched on and off in the portable terminal 20a on the vehicle, the train number and the train number and the travel are performed even if the GPS function is turned off. The position information can be acquired from the position. As described above, in the present invention, the position information of the mobile terminal 20a on the vehicle can be acquired by specifying the vehicle on which the vehicle is on and the vehicle position.

  The “position information” refers to information on the position of the mobile terminal specified from information on the composition and vehicle in which the mobile terminal exists and information on the current position of the composition.

  In addition, the period which acquires train information from the information delivery terminal 13-1 should just be a grade which does not produce a time lag, when the onboard information produced | generated from the acquired train information is displayed. In other words, when you arrive at the station and open the door, you will see the on-board information at the time of arrival at the station instead of the on-board information at the time of traveling. It is only necessary to display on-vehicle information. This period is, for example, 1 second.

  The mobile terminal 20a on the vehicle generates a screen with a design corresponding to the mobile terminal 20a on the vehicle from the train information of the information distribution terminal 13-1 acquired in a batch by the application of the content information distribution system. Is displayed (step S7). The user selects an item from the on-vehicle information display screen (step S8).

  When an item is selected from the display screen, the mobile terminal 20a on the vehicle requests data from the information distribution terminal 13-1 (step S9), and the information distribution terminal 13-1 generates data according to the request (step S10). The generated data is transmitted to the mobile terminal 20a on the vehicle (step S11), and the content information is displayed (step S12).

  However, when the train information transmitted in step S6 is the train information data itself, the content is displayed immediately after the item selection (step S8) without requesting the data from the information distribution terminal 13-1. Is performed (step S12).

  In this way, onboard information is displayed on the mobile terminal 20a on the vehicle by the application of the content information distribution system when boarding. As the on-board information, for example, as described above, a getting-off alarm can be cited.

  The “get-off alarm” refers to the getting-off station set by the user in the application of the mobile terminal 20a on the car and the train running state received from the distribution terminal 13-1, and the mobile terminal 20a on the car. An alarm generated by an application. The current position used at this time is included in boarding train information, which is information related to the entire train organization composed of a plurality of vehicles that are currently on board. The timing at which the getting-off alarm is issued (e.g., issued 1 minute before arrival) may be configured so that the user can appropriately set it by the application.

  Further, the getting-off alarm is not limited to the sound from the speaker unit of the mobile terminal 20a on the vehicle, and the casing of the mobile terminal 20a on the car may vibrate. Or you may use together the sound from a speaker part, and the vibration (sound) of a housing | casing.

  As described above, when the on-board information distributed from the information distribution terminal 13-1 includes the getting-off alarm and the delivery of the train information is completed within the vehicle, the vehicle on board is currently communicating with the outside and using GPS or the like. Even in situations where it is difficult to acquire the position (such as when passing through a tunnel), it is possible to reliably issue a getting-off alarm at a set timing. Further, when the GPS function can be switched on and off in the portable terminal 20a on the vehicle, the getting-off alarm can be used even when the GPS function is turned off, and the power consumption of the portable terminal 20a on the vehicle is reduced. Can be suppressed.

  In this way, the mobile terminal 20a on the vehicle periodically acquires the train information from the information distribution terminal 13-1 installed for each vehicle and displays the on-board information in real time so that there is no time lag. Can be displayed on the screen of the mobile terminal 20a on the vehicle.

  Moreover, since the information delivery terminal 13-1 should just transmit the same train information to all the users collectively, without processing information etc., a user is not requested | required of login authentication. Moreover, even if it is a case where the format etc. of train information are changed, the application of the portable terminal 20a on a vehicle may be updated and it may respond | correspond to the said format.

  In the present invention, the information distribution terminal 13-1 collectively transmits the same train information to all users, but the user can select an item from the display screen of the application of the content information distribution system. Unlike a guidance display board that uniformly provides public information as it is mounted on a conventional vehicle, it is possible to provide private information according to individual users. In other words, according to the present invention, it is possible to provide private information according to each user even though the same train information is transmitted to all users at once. In addition, because it is possible to provide private information according to individual users in this way, it is also possible for users to wear earphones and use synthesized voices to provide getting-off guidance etc. according to individual users It is.

  In addition, since the train information is acquired from the information distribution terminal 13-1, the user can connect to the Internet 41 via the communication carrier network 40 while acquiring train information for generating on-board information. is there. The ground information may be acquired from the content server 31 by connecting to the Internet 41 via the communication carrier network 40. Thus, when train information is acquired from the information distribution terminal 13-1, since it can be realized by short-range wireless communication without being influenced by the line quality of the communication carrier network 40, train information can be obtained without causing a time lag. It is possible to obtain and display on-vehicle information.

  “Ground information” refers to information that is distributed from a content server to a mobile terminal via the Internet and a carrier network and displayed on the mobile terminal when the user gets on and off.

  In addition, the information distribution terminal 13-1 collectively transmits train information, and the on-vehicle information display screen is generated by the portable terminal 20a on the vehicle based on the train information. For this reason, the information distribution terminal 13-1 does not have to generate a screen corresponding to each user, and it is only necessary to transmit the same information to all users, so the load on the information distribution terminal 13-1 can be suppressed. It is. In particular, since the information distribution terminal 13-1 transmits the same information regardless of the number of connected mobile terminals, the load on the information distribution terminal 13-1 does not increase even if the number of connected mobile terminals increases. Train information can be transmitted smoothly.

  In addition, when the communication between the information distribution terminal 13-1 and the mobile terminal 20a on the vehicle is performed by proximity wireless communication as in the past, the user approaches a reader / writer or an infrared transmission unit installed at a predetermined position of the vehicle. Had to do. In the present invention, since short-range wireless communication is used, it is not necessary to approach a reader / writer or an infrared transmitter, and train information can be acquired at any position in the vehicle and on-vehicle information can be displayed. It is.

  FIG. 3 shows the content server 31 and the mobile terminal 20a on the vehicle (or the mobile terminal on the ground) until the ground information is displayed on the mobile terminal 20a (or the mobile terminal 20b on the ground) when getting on (or getting off). It is a sequence diagram which shows the operation | movement of 20b). Here, as an example, the operations of the content server 31 and the ground mobile terminal 20b until the ground information is displayed on the ground mobile terminal 20b when getting off will be described.

  When the user gets off the vehicle 11-1, the mobile terminal 20b on the ground stops short-range wireless communication with the information distribution terminal 13-1, and the communication between the mobile terminal 20b on the ground and the information distribution terminal 13-1 is a communication business. It switches to those via the user network 40.

  When the user activates the application of the content information distribution system by operating the ground mobile terminal 20b, the ground mobile terminal 20b makes a connection request to the content server 31 via the communication carrier network 40 (step S21). This connection request includes a composition number (ID) when getting on and does not include a composition number when getting off. The content server 31 that has received the connection request performs a connection process (step S22), and transmits ground information to the ground mobile terminal 20b (step S23).

  The ground mobile terminal 20b generates a screen from the received ground information and displays the ground information (step S24). The user selects an item from the ground information display screen (step S25).

  When an item is selected from the display screen, the mobile terminal 20b on the ground requests data from the content server 31 (step S26), the content server 31 generates data according to the request (step S27), and the generated data is It is transmitted to the ground portable terminal 20b (step S28), and the content information is displayed (step S29).

  As described above, the ground information is displayed on the mobile terminal 20a on the vehicle or the mobile terminal 20b on the ground by the application of the content information distribution system both when getting on and off.

  Since the formation number is added to the connection request at the time of boarding, both the ground information depending on the boarding position and the ground information not depending on the boarding position are displayed by the application of the content information distribution system.

  When getting off, since the composition number is not added to the connection request, unlike the case of getting on, only the ground information independent of the boarding position is displayed by the application of the content information distribution system. In addition, since no train information exists when getting off, no on-board information is displayed.

  The ground information includes, for example, “operation guidance for timetable disruption”, “designated station equipment guidance and transfer guidance”, “transfer train information (including delay information, etc.)”, “departure status of the latest train”, “Advertising that does not depend on the boarding position” or the like. The “delay information” refers to information about whether or not the actual train is delayed with respect to the operation schedule and the degree of delay when the train is delayed.

  For the ground information, the mobile terminal 20a on the vehicle or the mobile terminal 20b on the ground inquires of the content server 31, and the screen of the design corresponding to the mobile terminal 20a on the vehicle or the mobile terminal 20b on the ground is displayed on the mobile terminal 20a on the vehicle or Distribution is performed by responding to the mobile terminal 20b on the ground. In both cases of getting on and off the vehicle, the mobile terminal 20a on the vehicle or the mobile terminal 20b on the ground is directly connected to the content server 31 connected to the Internet 41 via the communication carrier network 40. As described above, when the ground information is acquired, if it is configured to pass through the communication carrier network 40, the railway carrier communicates to connect the mobile terminal 20a on the vehicle or the mobile terminal 20b on the ground and the communication carrier network 40. There is no need to provide additional facilities, etc., and the running cost of railway operators can be reduced.

  In addition, at the time of boarding, all the information (vehicle information) that can be acquired from the information distribution terminal 13-1 has only to be acquired from the information distribution terminal 13-1, and the information (ground information) that cannot be acquired from the information distribution terminal 13-1. It is only necessary to connect to the content server 31 at the time of acquisition.

  The advertisement included in the ground information is classified into an advertisement that depends on the traveling position of the train and an advertisement that does not depend on the traveling position of the train. The content server 31 manages the train information of each train acquired from the train information management server 32 and grasps the travel position of the train 10. Therefore, the advertisement depending on the traveling position of the train is acquired from the content server 31 based on the traveling position. The advertisement that does not depend on the traveling position of the train is the same when getting on and off.

  That is, when the composition number is added to the connection request, a dedicated page for boarding is displayed on the mobile terminal 20a on the vehicle, and when the composition number is not added to the connection request, the mobile terminal 20b on the ground is displayed. Displays a dedicated page for getting off (general information page). Thus, in the content information distribution system of the present invention, the screen generated when getting on and the screen generated when getting off are different.

  Moreover, in the content information delivery system of this Embodiment, although the train information management apparatuses are connected, the information delivery terminals are not connected. Therefore, similarly to the conventional train, the connection between the different vehicles may be only the connection between the train information management devices, and there is no need to newly provide a connection point. Therefore, even if one of the vehicles has a failure or a malfunction and it is necessary to replace the vehicle in the train formation, the replacement can be easily performed.

Embodiment 2. FIG.

In the content information distribution system shown in FIG. 4, the vehicles 11-1 to 11-n are provided with information distribution terminals and radio apparatuses 13-1a to 13-na instead of the information distribution terminals 13-1 to 13-n. ing. The mobile terminal 20a on the vehicle is connected to the communication carrier network 40 via the information distribution terminal / wireless device 13-1a.

  In FIG. 4, unlike FIG. 1, an authentication server 42 is arranged between the telecommunications carrier network 40 and the content server 31. The information distribution terminal / wireless device 13-1a is connected to the content server 31 and the Internet 41 via the authentication server 42. In addition, the authentication server 42 performs login authentication, so that it is possible to ask for consent to the terms of use before using the service.

  In this way, the information distribution terminal / radio device provided in the train can provide the connection between the portable terminal 20a on the vehicle and the content server 31. With such a configuration, all information is distributed from the information distribution terminal and wireless device 13-1a to the portable terminal 20a on the vehicle by short-range wireless communication. Even a mobile terminal that does not have a subscriber or a line contract can use the system stably.

  In the first embodiment and the present embodiment, the mobile terminal generates a screen when displaying ground information on the mobile terminal, but the present invention is not limited to this. When the ground information is displayed on the mobile terminal, the content server may generate a screen and the ground information may be displayed on the mobile terminal.
