DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] A preferred embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings. Note that the present disclosure is not limited to the following description, and can be modified as appropriate without departing from the gist of the present disclosure. In addition, in this specification and drawings, components having substantially the same functions are denoted by the same reference numerals, and duplicated descriptions are omitted.

[0012] In the present disclosure, in a boarding information collection system, information on passengers' (users') train boarding histories (hereinafter referred to as boarding information) is collected in a server (passenger support server 30 described later) at any time. Then, in the passenger support system (user support system), various services are provided to passengers using the collected boarding information. First, the configuration of the boarding information collection system that collects the boarding information will be described below as a first embodiment. Next, the configuration of a passenger support system that provides various services using the boarding information will be described as embodiments 2 to 5.

[0013] Embodiment 1 (Configuration of the ride information collection system) The configuration of the ride information collecting system according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing the configuration of the ride information collecting system according to the first embodiment.

[0014] 1, a ride information collecting system 1 according to the first embodiment includes an information distribution device 10 installed in a vehicle 101, a mobile terminal 20 carried by a passenger, and a passenger support server 30 (corresponding to an information processing device in this disclosure) that collects ride information. Although not shown, the information distribution device 10, the mobile terminal 20, and the passenger support server 30 each have a communication device that communicates with an external device using a predetermined communication method. The information distribution device 10 and the mobile terminal 20, and the mobile terminal 20 and the passenger support server 30 are connected to each other so as to be able to communicate with each other via the communication device.

[0015] 1 representatively illustrates one information distribution device 10 and one mobile terminal 20, the number of information distribution devices 10 installed is not limited as long as the information distribution device 10 is installed so as to be able to distribute information to all mobile terminals 20 present in the vehicle 101. For example, only one information distribution device 10 may be installed in one vehicle 101, or multiple information distribution devices 10 may be installed. Also, the number of mobile terminals 20 may correspond to the number of passengers aboard the vehicle 101.

[0016] The information distribution device 10 distributes information to the surrounding mobile terminals 20 by wireless communication. For example, the information distribution device 10 is a beacon device that distributes information using Bluetooth (registered trademark). The communication method between the information distribution device 10 and the mobile terminals 20 is not limited, and various known communication methods such as Wi-Fi (registered trademark) may be used in addition to the above-mentioned Bluetooth. However, it is preferable that the information distribution device 10 communicates at a short distance (for example, 10 m or less) like the above-mentioned beacon device so as not to distribute information to the mobile terminals of passengers outside the vehicle (for example, the mobile terminals of passengers on the platform of a station). In this case, it is preferable that a plurality of information distribution devices 10 are installed in one vehicle 101 so that information can be distributed to all the mobile terminals 20 present in the vehicle 101.

[0017] In the first embodiment, the information distribution device 10 distributes train identification information of the train and the vehicle in which the information distribution device 10 is installed to the mobile terminal 20. The train identification information is information for identifying at least the train, and includes, for example, vehicle number information indicating the vehicle number uniquely assigned to each vehicle, vehicle formation number information indicating the vehicle formation, operation information including the starting station, the terminal station, and the passing time of each station between the starting station and the terminal station, and date and time information indicating the current date and time (i.e., the date and time of distribution of the train identification information). The contents of the train identification information are not limited to the above example. The train identification information only needs to be configured to be able to identify at least the train, and the specific configuration may be arbitrary. The specific configuration of the train identification information may be appropriately set by the designer, provider, etc. of the boarding information collection system 1. For example, in the above example, since the train identification information includes the vehicle number information, not only the train but also the vehicle can be identified by the train identification information.

[0018] The information distribution device 10 is provided with operation information from, for example, a control device installed in a train that controls train operation management. The operation information is information related to train operation, and includes, in addition to the information included in the train identification information described above, for example, train type information indicating the type of train (local, express, limited express, etc.), train location information indicating the current location of the train, and next station information indicating the next station. The information distribution device 10 configures train identification information from the operation information and distributes it to the mobile terminal 20. Here, if a display device that provides operation information and the like to passengers is installed in the vehicle 101, the above-mentioned control device transmits operation information to the display device, so the information distribution device 10 may be installed next to the display device and receive operation information from the control device together with or via the display device. Note that the method by which the information distribution device 10 receives operation information is not limited to the above example. For example, the information distribution device 10 may directly receive operation information from a traffic control system outside the train (on the ground) by wireless communication via a base station installed at a station or along the line.

[0019] The information distribution device 10 transmits train identification information at predetermined intervals (e.g., intervals of about several hundred milliseconds) to the mobile terminal 20 as needed. The transmission interval of the train identification information may be set arbitrarily by the designer, provider, etc. of the boarding information collection system, but in order to reliably transmit train identification information to the mobile terminal 20 of a passenger who rides for only one station, it is preferable to set the time interval to a time interval shorter than the travel distance of the train between one station (e.g., intervals of about several hundred milliseconds as described above).

[0020] The mobile terminal 20 is a terminal having a communication function, and is, for example, a general-purpose device such as a smartphone or a tablet PC. Alternatively, the mobile terminal 20 may be a dedicated terminal for the services according to the first embodiment and the second to fifth embodiments described later. When the mobile terminal 20 is a dedicated terminal, the railway operator can lend the mobile terminal 20 to passengers, thereby making it possible to provide these services to passengers who do not have a terminal such as a smartphone, or to travelers from overseas. Note that, in FIG. 1, only the functions of the mobile terminal 20 related to the collection of boarding information according to the first embodiment are illustrated. In addition to the functions illustrated, the mobile terminal 20 has various functions that a general mobile terminal has, such as a display unit that displays information and an input unit that accepts operation input.

[0021] The mobile terminal 20 has a boarding information generating unit 201 as one of its functions. When the mobile terminal 20 is carried by a passenger and brought into the vehicle 101, the mobile terminal 20 wirelessly communicates with the information distribution device 10 and receives train identification information. The boarding information generating unit 201 assigns its own mobile terminal identification information to the train identification information received from the information distribution device 10. The mobile terminal identification information is information for identifying the mobile terminal 20, and is, for example, information about a MAC (Media Access Control) address assigned to the mobile terminal 20. Note that the mobile terminal identification information is not limited to information about the MAC address, and may be any information that can identify the mobile terminal 20, and the specific content of the information may be arbitrary.

[0022] The train identification information received by the mobile terminal 20 (i.e., the train identification information corresponding to the train on which the passenger carrying the mobile terminal 20 has boarded) and the mobile terminal identification information assigned (associated) to the train identification information are information indicating the boarding history of the passenger carrying the mobile terminal 20, i.e., correspond to the boarding information. In other words, the boarding information generating unit 201 assigns its own mobile terminal identification information to the train identification information and associates the two, thereby generating boarding information for the passenger carrying the mobile terminal 20.

[0023] The mobile terminal 20 communicates with a passenger assistance server 30 provided on the ground via a communication network, and transmits the boarding information generated by the boarding information generating unit 201 to the passenger assistance server 30. The mobile terminal 20 generates boarding information every time it receives train identification information from the information distribution device 10, and transmits the boarding information to the passenger assistance server 30 as needed. Therefore, the mobile terminal 20 transmits the boarding information to the passenger assistance server 30 as needed while it is inside the vehicle 101 (i.e., while a passenger carrying the mobile terminal 20 is on board the vehicle 101), but does not transmit the boarding information to the passenger assistance server 30 while it is outside the vehicle 101 (i.e., before the passenger carrying the mobile terminal 20 gets on board the vehicle 101 and after he gets off the vehicle 101).

[0024] The function of the ride information generating unit 201 can be realized by installing a dedicated application on the mobile terminal 20. That is, the ride information generating unit 201 is configured with a processor such as a CPU (Central Processing Unit) or a DSP (Digital Signal Processor) and a storage element such as a memory, and the processor executes arithmetic processing according to a predetermined program stored in the storage element, thereby realizing the function of the ride information generating unit 201. When the application is installed or used, the passenger may consent to providing attribute information (such as name, age, telephone number, and email address). If consent is obtained, the passenger's attribute information provided in advance may be managed in the passenger support server 30. Alternatively, if consent is obtained, when the mobile terminal 20 transmits ride information to the passenger support server 30, attribute information previously stored in the mobile terminal 20, such as a telephone number, may be transmitted together.

[0025] The passenger support server 30 is a server for managing passenger boarding information and providing passengers with various services using the passenger information. The passenger support server 30 has, as one of its functions, a boarding information DB (DataBase) 301 for storing boarding information. Note that FIG. 1 illustrates only the functions of the passenger support server 30 related to the collection of boarding information according to the first embodiment. In addition to the functions illustrated, the passenger support server 30 has various functions that a general server has, such as a display unit for displaying information and an input unit for accepting operational input.

[0026] The boarding information DB301 is configured with a non-volatile storage device such as an HDD (Hard Disk Drive) or a flash memory. The boarding information DB301 manages the boarding history of passengers by storing the boarding information transmitted from the mobile terminal 20 (i.e., storing the mobile terminal identification information and the train identification information in association with each other). The boarding information DB301 stores the boarding information for the multiple mobile terminals 20 present in the vehicle 101 every time the boarding information is transmitted from the mobile terminal 20. In this way, the boarding information is successively accumulated in the boarding information DB301.

[0027] In this case, it is preferable that the boarding information DB301 manages the boarding information for each mobile terminal identification information in the chronological order in which it was received. This makes it possible to manage the boarding history for each mobile terminal 20 (i.e., for each passenger) corresponding to the mobile terminal identification information, and makes it easy to refer to the boarding history of a specific passenger. As described above, the mobile terminal 20 transmits boarding information to the passenger support server 30 only while the mobile terminal 20 is in the vehicle 101. Therefore, by referring to the boarding information DB301, it becomes possible to identify the boarding date and time, disembarking date and time, and boarding section of the passenger who owns the mobile terminal 20, based on the boarding information first received in a certain time period, the boarding information last received, and information on the date and time when the information distribution device 10 distributed the train identification information contained in the boarding information.

[0028] The above describes the configuration of the ride information collecting system 1. In the following embodiments 2 to 5, the passenger support server 30 provides various services to passengers using the ride information collected by the above-described ride information collecting system 1. These services will be described in detail below.

[0029] Embodiment 2 (Simplifying reporting of lost items) (Passenger Support System Configuration) The configuration of a passenger support system that realizes a service for simplifying the reporting of items left behind on trains will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the configuration of a passenger support system related to the reporting of items left behind on trains according to the second embodiment.

[0030] Referring to FIG. 2, the passenger assistance system 2 (user assistance system 2) includes a mobile terminal 20a, a passenger assistance server 30a (corresponding to an information processing device in this disclosure), and a lost property management system 40. The mobile terminal 20a is the same terminal as the mobile terminal 20 that transmits ride information to the passenger assistance server 30 in the ride information collection system 1 shown in FIG. 1. The passenger assistance server 30a is the same device as the passenger assistance server 30 in the ride information collection system 1 shown in FIG. 1. In FIG. 2, for the mobile terminal 20a and the passenger assistance server 30a, only functions for realizing the service according to the second embodiment are illustrated, and since the functional configuration is different from that shown in FIG. 1, these are formally assigned different reference numerals. Although not illustrated, the mobile terminal 20a, the passenger assistance server 30a, and the lost property management system 40 have communication devices that communicate with external devices using a predetermined communication method. The mobile terminal 20a and the passenger assistance server 30a, and the passenger assistance server 30a and the lost property management system 40 are connected to each other so as to be able to communicate with each other via the communication device.

[0031] The mobile terminal 20a has, as its functions, an input unit 203, a notification information generating unit 205, a display unit 207, and a display control unit 209.

[0032] The input unit 203 is an interface that accepts various operational inputs from passengers. The input unit 203 is configured with an input device such as a touch panel, a button, and / or a keyboard. If the mobile terminal 20a has a voice input function, the input unit 203 may be configured with a microphone. In the second embodiment, when a passenger reports to a railway operator that he or she has left an item on a train, the passenger inputs information indicating the characteristics of the lost item (type, color, shape, etc.) from the input unit 203 (hereinafter, referred to as lost item information). The input unit 203 provides the input lost item information to the report information generation unit 205.

[0033] The report information generating unit 205 generates report information, which is information about reporting lost items, by adding its own mobile terminal identification information to the lost item information provided by the input unit 203. The report information generating unit 205 transmits the generated report information to the lost item inquiry unit 303 of the passenger support server 30a, which will be described later.

[0034] The display unit 207 visually displays various types of information under the control of the display control unit 209. The display unit 207 is configured by various types of known display devices, such as a liquid crystal display device or an organic EL (Electro Luminescence) display device.

[0035] The display control unit 209 controls the display of the display unit 207 and causes the display unit 207 to display various information. In the second embodiment, the display control unit 209 causes the display unit 207 to display guidance when lost-item information is input from the input unit 203. In this case, if the input unit 203 is configured with a touch panel, the input unit 203 and the display unit 207 may be integrated as a display device with a touch sensor, and the display control unit 209 may cause the display unit 207 to display an input screen for lost-item information. In addition, the display control unit 209 causes the display unit 207 to display information on the result of an inquiry to the lost-item management system 40 about the presence or absence of a lost item (hereinafter referred to as inquiry result information), which is transmitted from the lost-item inquiry unit 303 of the passenger support server 30a described later.

[0036] The passenger support server 30a has, as its functions, a boarding information DB 301 and a lost property inquiry unit 303. The boarding information DB 301 is the same as the boarding information DB 301 shown in Fig. 1, and stores boarding information of passengers.

[0037] When the lost property inquiry unit 303 receives the report information from the report information generation unit 205 of the mobile terminal 20, it refers to the boarding information DB 301 to obtain the train identification information associated with the mobile terminal identification information included in the report information. That is, the lost property inquiry unit 303 obtains the train identification information of the train on which the passenger who reported the lost property (i.e., the passenger who possesses the mobile terminal 20a that sent the report information) was riding. The lost property inquiry unit 303 transmits the obtained train identification information and the lost property information included in the report information received from the mobile terminal 20a to the lost property management DB comparison unit 403 of the lost property management system 40 described later, and inquires whether there is a lost property corresponding to the lost property information.

[0038] The lost item inquiry unit 303 also receives information on the inquiry result (hereinafter referred to as inquiry result information) from the lost item management DB comparison unit 403 of the lost item management system 40, which will be described later. The lost item inquiry unit 303 then transmits the inquiry result information to the display control unit 209 of the mobile terminal 20a. As described above, in the mobile terminal 20a, the display control unit 209 causes the display unit 207 to display the received inquiry result information. This notifies the passenger of the inquiry result to the lost item management system 40 regarding the lost item reported by the passenger.

[0039] The lost property inquiry unit 303 may obtain the contact information (e.g., telephone number, email address, etc.) of the mobile terminal 20a by inquiring of the carrier of the mobile terminal 20a based on the mobile terminal identification information (e.g., MAC address) transmitted from the mobile terminal 20a. Alternatively, if the mobile terminal identification information transmitted from the mobile terminal 20a includes information on the contact information as passenger attribute information, the lost property inquiry unit 303 may transmit inquiry result information to the mobile terminal 20a based on the information on the contact information.

[0040] The lost property management system 40 is a system owned by a railway operator, and manages information about items left on trains. The lost property management system 40 has a lost property management DB 401 and a lost property management DB collation unit 403 as its functions.

[0041] The lost property management DB 401 is configured with a non-volatile storage device such as a HDD or a flash memory. The lost property management DB 401 is a database that stores lost property information and train identification information of the train in which the lost property related to the lost property information was found, in association with each other. The lost property management DB 401 stores lost property information and train identification information as needed by the railway operator when a property is left on a train.

[0042] When the lost property management DB comparison unit 403 receives the train identification information obtained from the boarding information DB 301 (i.e., the train identification information indicating the boarding history of the passenger who reported the lost property) and the lost property information included in the report information sent from the mobile terminal 20a from the lost property inquiry unit 303 of the passenger assistance server 30a, it compares these pieces of information with the train identification information and the lost property information stored in the lost property management DB 401. If the lost property management DB 401 stores the corresponding train identification information and the lost property information, the lost property management DB comparison unit 403 determines that there is a match. On the other hand, if the lost property management DB 401 does not store the corresponding train identification information and the lost property information, the lost property management DB comparison unit 403 determines that there is no match.

[0043] The lost property management DB matching unit 403 transmits information on the matching result to the lost property inquiry unit 303 of the passenger assistance server 30a as inquiry result information. At this time, if the matching result is "matched", the lost property management DB matching unit 403 transmits, as the inquiry result information, information that the reported lost property is registered in the lost property management DB 401, information on the storage location of the lost property, and information on the specific contact information for picking up the lost property. On the other hand, if the matching result is "not matched", the lost property management DB matching unit 403 transmits, as the inquiry result information, information that the reported lost property is not registered in the lost property management DB 401. As described above, the inquiry result information is transmitted to the mobile terminal 20a via the lost property inquiry unit 303 of the passenger assistance server 30a and is displayed.

[0044] The above-described report information generating unit 205 and display control unit 209 of the mobile terminal 20a, the lost property inquiry unit 303 of the passenger support server 30a, and the lost property management DB matching unit 403 of the lost property management system 40 are configured by a processor such as a CPU or DSP, and a storage element such as a memory. The above-described functions are realized by the processor executing arithmetic processing according to a predetermined program stored in the storage element. The functions of the report information generating unit 205 and the display control unit 209 of the mobile terminal 20a may be realized by a passenger who wishes to receive the service according to the second embodiment installing a dedicated app on the mobile terminal 20a. In other words, a program or app for realizing each of the above-described functions can be created and implemented in an information processing device such as a server or a mobile terminal. The program or app may be distributed via a network. Alternatively, a computer-readable recording medium in which such a program or app is stored may be provided. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like.

[0045] The configuration of the passenger assistance system 2 according to the second embodiment has been described above. Note that the configuration shown in Fig. 2 is merely one example of the configuration of the passenger assistance system 2, and the passenger assistance system 2 may be configured so as to realize each of the functions described above as a whole, and the specific configuration may be arbitrary. For example, the passenger assistance server 30a and the lost property management system 40 may be configured integrally, and each function of the passenger assistance server 30a may be implemented in the lost property management system 40.

[0046] (Information processing method in passenger support system) The processing procedure of the information processing method in the passenger support system 2 described above will be described with reference to Fig. 3. Fig. 3 is a flow diagram showing the processing procedure of the information processing method in the passenger support system 2 according to the second embodiment. Note that the details of each process shown in Fig. 3 have already been explained when explaining the configuration of the passenger support system 2 with reference to Fig. 2, so detailed explanations will be omitted here.

[0047] In the information processing method in the passenger support system 2 according to the second embodiment, first, the mobile terminal 20a acquires lost property information (step S101). Next, the mobile terminal identification information is added to the acquired lost property information to generate report information (step S103). Next, the generated report information is transmitted to the passenger support server 30a (step S105). The processes shown in steps S101 to S105 correspond to the processes executed by the report information generation unit 205 of the mobile terminal 20a described with reference to FIG. 2.

[0048] Next, the passenger assistance server 30a refers to the boarding information DB 301 and acquires the train identification information associated with the mobile terminal identification information included in the report information (step S107). Next, the acquired train identification information and the lost property information included in the report information are transmitted to the lost property management system 40 (step S109). The processes shown in steps S107 and S109 correspond to the processes executed by the lost property inquiry unit 303 of the passenger assistance server 30a described with reference to FIG. 2.

[0049] Next, in the lost property management system 40, the train identification information and the lost property information included in the report information obtained from the boarding information DB 301 of the passenger assistance server 30a are compared with the train identification information and the lost property information registered in the lost property management DB 401 (step S111). Next, the query result information is sent to the passenger assistance server 30a (step S113). The processes shown in steps S111 and S113 correspond to the processes executed by the lost property management DB comparison unit 403 of the lost property management system 40 described with reference to FIG. 2.

[0050] Next, the passenger support server 30a transmits the inquiry result information to the mobile terminal 20a (step S115). The process shown in step S115 corresponds to the process executed by the lost property inquiry unit 303 of the passenger support server 30a described with reference to FIG.

[0051] Next, the inquiry result information is displayed on the mobile terminal 20a (step S117). That is, the passenger who reported the lost item is notified of the result of inquiring the lost item management system 40 of the railway operator about the presence or absence of the lost item. The process shown in step S117 corresponds to the process executed by the display control unit 209 of the mobile terminal 20a described with reference to FIG. 2.

[0052] The processing procedure of the information processing method according to the second embodiment has been described above.

[0053] As described above, according to the passenger assistance system 2 of embodiment 2, when a passenger wishes to report a lost item and inputs the lost item information, the passenger assistance server 30a identifies the train identification information of the train the passenger was riding on, and checks whether or not the passenger has left any items behind based on the train identification information.

[0054] Conventionally, when reporting lost property, passengers themselves had to input information about the train they left the property on. However, passengers do not always remember the exact time they boarded the train, and may not be able to identify the train they were on.

[0055] In contrast, according to the passenger support system 2 according to the second embodiment, as described above, when reporting a lost item, the passenger only needs to input information about the lost item, and does not need to input information about the train. This simplifies the process of reporting a lost item, and improves passenger convenience.

[0056] In addition, when the lost property management system 40 manages lost property by car, not by train, by configuring the train identification information to include car number information as in the example described above in the first embodiment, it becomes possible to identify the car in which the passenger was riding and to check whether or not there is any lost property in that car in the lost property management system 40. This makes it possible to check lost property more accurately.

[0057] Embodiment 3 (Notification of riding with an infected person) (Passenger Support System Configuration) A configuration of a passenger support system that realizes a service of notifying passengers of a ride with an infected person will be described with reference to Fig. 4. Fig. 4 is a block diagram showing a configuration of a passenger support system related to a ride with an infected person notification according to a third embodiment.

[0058] Referring to FIG. 4, the passenger support system 3 (user support system 3) includes a mobile terminal 20b, a passenger support server 30b (corresponding to an information processing device in this disclosure), and an infected person management system 50. The mobile terminal 20b is the same terminal as the mobile terminal 20 that transmits ride information to the passenger support server 30 in the ride information collection system 1 shown in FIG. 1. The passenger support server 30b is the same device as the passenger support server 30 in the ride information collection system 1 shown in FIG. 1. In FIG. 4, for the mobile terminal 20b and the passenger support server 30b, only functions for realizing the service according to the third embodiment are illustrated, and since the functional configuration is different from that shown in FIG. 1, these are formally assigned different symbols. Although not illustrated, the mobile terminal 20b, the passenger support server 30b, and the infected person management system 50 have communication devices that communicate with external devices using a predetermined communication method. The mobile terminal 20b and the passenger assistance server 30b, and the passenger assistance server 30b and the infected person management system 50 are connected to each other via the communication device so as to be able to communicate with each other.

[0059] The infected person management system 50 is a system that manages information about infected persons with a specific infectious disease (for example, an infectious disease designated in the Infectious Diseases Act, such as COVID-19). The infected person management system 50 has, as its functions, an infected person management DB 501 and an infected person notification information generation unit 503.

[0060] The infected person management DB 501 is configured with a non-volatile storage device such as a HDD or a flash memory. The infected person management DB 501 stores information about infected people. The infected person management DB 501 stores at least mobile terminal identification information of the mobile terminal 20 possessed by the infected person and information about the date and time when the infection was discovered (hereinafter referred to as infection discovery date and time information) in association with each other as information about the infected person. The infected person management DB 501 may further store, as information about the infected person, information such as the contact information (telephone number, email address, etc.) of the infected person, address, age, and sex. Every time an infected person occurs, information about the infected person is registered in the infected person management DB 501 as needed by, for example, a medical professional such as a doctor who has confirmed the infection.

[0061] The infected person notification information generating unit 503 generates information for notifying the passenger support server 30b of an infected person (hereinafter referred to as infected person notification information). Specifically, when a new infected person is discovered and information about the infected person is registered in the infected person management DB 501, the infected person notification information generating unit 503 acquires mobile device identification information and infection detection date and time information about the newly infected person from the infected person management DB 501, and generates infected person notification information consisting of these pieces of information. The infected person notification information generating unit 503 transmits the generated infected person notification information (i.e., the mobile device identification information and infection detection date and time information) to the passenger notification unit 305 of the passenger support server 30b described later.

[0062] The passenger support server 30b has, as its functions, a boarding information DB 301 and a fellow passenger notification unit 305. The boarding information DB 301 is the same as the boarding information DB 301 shown in Fig. 1, and stores the boarding information of passengers.

[0063] When the passenger notification unit 305 receives the infected person notification information from the infected person notification information generating unit 503 of the infected person management system 50, the passenger notification unit 305 identifies passengers who were on the same train as the infected person corresponding to the infected person notification information based on the boarding information stored in the boarding information DB 301. Specifically, the passenger notification unit 305 refers to the boarding information DB 301 and checks whether there is boarding information corresponding to the mobile terminal identification information included in the received infected person notification information. At this time, the passenger notification unit 305 identifies a period that goes back by the incubation period of the target infectious disease from the date and time when the infection was detected indicated in the infection detection date and time information based on the infection detection date and time information included in the received infected person notification information. Then, the passenger notification unit 305 checks whether there is boarding information corresponding to the period based on information about the date and time when the train identification information was delivered included in the train identification information. In other words, the passenger notification unit 305 checks whether there is boarding information for the period from when the infected person was infected to when the onset of symptoms occurred through the incubation period.

[0064] If there is corresponding boarding information, the passenger notification unit 305 identifies the train identification information included in the boarding information. The passenger notification unit 305 further refers to the boarding information DB 301 and identifies other mobile terminal identification information associated with the same train identification information as the identified train identification information. This identifies the mobile terminal identification information of the mobile terminal 20b of the passenger who was on the same train as the infected person. The passenger notification unit 305 transmits a notification (hereinafter, referred to as a passenger notification) to the mobile terminal 20b corresponding to the identified mobile terminal identification information that the passenger was on the same train as the infected person. The passenger notification unit 305 may obtain the contact information (e.g., telephone number, email address, etc.) of the mobile terminal 20b by inquiring of the carrier of the mobile terminal 20b based on the mobile terminal identification information (e.g., MAC address) included in the boarding information. Alternatively, if the mobile terminal identification information includes information on the contact information as the passenger's attribute information, the passenger notification unit 305 may transmit the passenger notification to the mobile terminal 20b based on the information on the contact information.

[0065] On the other hand, if there is no corresponding boarding information, the passenger notification unit 305 determines that the infected person did not board the train during the corresponding period, and ends the process.

[0066] The mobile terminal 20b has, as its functions, a display unit 207 and a display control unit 209. The display unit 207 and the display control unit 209 are configured with the same hardware as the display unit 207 and the display control unit 209 of the mobile terminal 20a according to the second embodiment, and have the same functions. That is, the display unit 207 visually displays various information under the control of the display control unit 209. In addition, the display control unit 209 controls the display of the display unit 207, and causes the display unit 207 to display various information. Specifically, in the third embodiment, the display control unit 209 causes the display unit 207 to display a passenger notification transmitted from the passenger notification unit 305 of the passenger support server 30b.

[0067] The display control unit 209 of the mobile terminal 20b, the passenger notification unit 305 of the passenger support server 30b, and the infected person notification information generation unit 503 of the infected person management system 50 described above are configured with a processor such as a CPU or DSP, and a storage element such as a memory. The processor executes arithmetic processing according to a predetermined program stored in the storage element, thereby realizing each of the above functions. The function of the display control unit 209 of the mobile terminal 20b may be realized by a passenger who wishes to receive the service according to the third embodiment installing a dedicated app on the mobile terminal 20b. In other words, it is possible to create a program or app for realizing each of the above functions and implement it in an information processing device such as a server or a mobile terminal. The program or app may be distributed via a network. Alternatively, a computer-readable recording medium in which such a program or app is stored may be provided. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like.

[0068] The configuration of the passenger support system 3 according to the third embodiment has been described above. Note that the configuration shown in Fig. 4 is merely one example of the configuration of the passenger support system 3, and the passenger support system 3 may be configured so as to realize each of the functions described above as a whole, and the specific configuration may be arbitrary. For example, the passenger support server 30b and the infected person management system 50 may be configured integrally, and each function of the passenger support server 30b may be implemented in the infected person management system 50.

[0069] (Information processing method in passenger support system) The processing procedure of the information processing method in the passenger support system 3 described above will be described with reference to Fig. 5. Fig. 5 is a flow diagram showing the processing procedure of the information processing method in the passenger support system 3 according to the third embodiment. Note that the details of each process shown in Fig. 5 have already been explained when explaining the configuration of the passenger support system 3 with reference to Fig. 4, and therefore detailed explanations will be omitted here.

[0070] In the information processing method in the passenger support system 3 according to the third embodiment, first, infected person notification information is generated in the infected person management system 50 (step S201). Next, the generated infected person notification information is transmitted to the passenger support server 30b (step S203). The processes shown in steps S201 and S203 correspond to the processes executed by the infected person notification information generation unit 503 of the infected person management system 50 described with reference to FIG. 4.

[0071] Next, in the passenger support server 30b, passengers who rode in the same train as the infected person corresponding to the infected person notification information are identified based on the boarding information stored in the boarding information DB301. Specifically, the boarding information DB301 is referenced to confirm the presence or absence of boarding information corresponding to the mobile terminal identification information included in the infected person notification information (step S205). At this time, based on the infection detection date and time information included in the infected person notification information, the presence or absence of boarding information during the period going back by the incubation period of the target infectious disease from the date and time of infection indicated in the infection detection date and time information is confirmed. Then, if the corresponding boarding information exists, the boarding information DB301 is further referenced to identify other mobile terminal identification information associated with the same train identification information as the train identification information included in the identified boarding information (step S207). A passenger who possesses a mobile terminal 20b corresponding to the identified mobile terminal identification information is identified as a passenger who rode in the same train as the infected person corresponding to the infected person notification information.

[0072] Next, a passenger notification is transmitted to the mobile terminal 20b corresponding to the specified mobile terminal identification information (step S209). The process shown in steps S205 to S209 corresponds to the process executed by the passenger notification unit 305 of the passenger support server 30b described with reference to FIG.

[0073] Next, the portable terminal 20b displays a passenger-sharing notification (step S211). That is, the portable terminal 20b of the target passenger displays a message indicating that the passenger was on the same train as a person infected with a predetermined infectious disease. The process shown in step S211 corresponds to the process executed by the display control unit 209 of the portable terminal 20b described with reference to FIG. 4.

[0074] The processing procedure of the information processing method in the passenger support system 3 according to the third embodiment has been described above.

[0075] As described above, according to the passenger assistance system 3 of the third embodiment, the passenger's mobile terminal 20b is notified that the passenger was on the same train as a person infected with a predetermined infectious disease. Therefore, the passenger who received the notification can pay attention to his / her physical condition management thereafter and can maintain his / her health. In addition, the passenger can take measures to prevent the passenger from further infecting a third party by considering himself / herself as an infected person, such as refraining from going out, thereby preventing the spread of infection in society. In addition, in the passenger assistance system 3, if the passenger applies for the provision of services related to the passenger assistance system 3, for example by installing an app, the passenger assistance system 3 automatically transmits a passenger assistance notification to the passenger when it is found that the passenger is on the same train as a person infected with a predetermined infectious disease, even if the passenger does not request the transmission of the passenger assistance notification (for example, a so-called PUSH notification is sent). In other words, the passenger can receive the passenger assistance notification without performing any special operation, which is very convenient.

[0076] In the above-described configuration example, the train on which the infected person was riding was identified based on the boarding information, and passengers riding on the train were identified, but as described in the first embodiment, if the train identification information includes car number information and is configured to be able to identify the car 101, the car 101 on which the infected person was riding and the passengers riding on the car 101 may be identified. Then, the mobile terminal 20b of the identified passenger may be notified that the passenger was riding on the same car 101 as the infected person. This makes it possible to more accurately identify passengers who were riding near the infected person. Embodiment 4 (Delivery of Delay Certificate) (Passenger Support System Configuration) A configuration of a passenger support system that realizes a service for distributing delay certificates will be described with reference to Fig. 6. Fig. 6 is a block diagram showing a configuration of a passenger support system related to the distribution of delay certificates according to the fourth embodiment.

[0077] Referring to FIG. 6, the passenger support system 4 (user support system 4) includes a mobile terminal 20c, a passenger support server 30c (corresponding to an information processing device in this disclosure), and a traffic management system 60. The mobile terminal 20c is the same terminal as the mobile terminal 20 that transmits the ride information to the passenger support server 30 in the ride information collection system 1 shown in FIG. 1. The passenger support server 30c is the same device as the passenger support server 30 in the ride information collection system 1 shown in FIG. 1. In FIG. 6, for the mobile terminal 20c and the passenger support server 30c, only functions for realizing the service according to the fourth embodiment are illustrated, and since functional configurations different from those shown in FIG. 1 are illustrated, they are formally assigned different reference numerals. Although not illustrated, the mobile terminal 20c, the passenger support server 30c, and the traffic management system 60 have communication devices that communicate with external devices in a predetermined communication format. The mobile terminal 20c and the passenger support server 30c, and the passenger support server 30c and the traffic management system 60 are connected to each other so as to be able to communicate with each other via the communication devices.

[0078] The traffic control system 60 is a system owned by a railway operator, and is a system that manages information related to train operations, such as position information of trains running on the line and information on delays from the timetable. The traffic control system 60 has a delay notification information generating unit 601 as one of its functions. Note that FIG. 6 illustrates only the functions of the traffic control system 60 for realizing the service according to the fourth embodiment. Although not illustrated, the traffic control system 60 has various functions that a general train traffic control system has, in addition to the delay notification information generating unit 601.

[0079] When a delay that meets the criteria for issuing a delay certificate occurs in a train operation, the delay notification information generating unit 601 generates information (hereinafter referred to as delay notification information) for notifying the passenger assistance server 30c of the delay. The delay notification information includes at least train identification information of the train where the delay occurred and information about the delay certificate for the delay. The delay notification information generating unit 601 transmits the generated delay notification information to a delay certificate distribution unit 307 of the passenger assistance server 30c, which will be described later.

[0080] The passenger support server 30c has, as its functions, a boarding information DB 301 and a delay certificate distribution unit 307. The boarding information DB 301 is the same as the boarding information DB 301 shown in Fig. 1, and stores the boarding information of passengers.

[0081] When the delay certificate distribution unit 307 receives delay notification information from the delay notification information generation unit 601 of the traffic management system 60, it identifies the mobile terminal 20c to which the delay certificate is to be distributed, based on the boarding information stored in the boarding information DB 301. Specifically, the delay certificate distribution unit 307 refers to the boarding information DB 301 and identifies the mobile terminal identification information associated with the train identification information included in the delay notification information. The mobile terminal 20c corresponding to the mobile terminal identification information is the target for distribution of the delay certificate.

[0082] The delay certificate distribution unit 307 transmits information about the delay certificate to the mobile terminal 20c corresponding to the identified mobile terminal identification information. The delay certificate distribution unit 307 may acquire the contact information (e.g., telephone number, email address, etc.) of the mobile terminal 20c by inquiring of the carrier of the mobile terminal 20c based on the mobile terminal identification information (e.g., MAC address) included in the boarding information. Alternatively, if the mobile terminal identification information includes information about the contact information as passenger attribute information, the delay certificate distribution unit 307 may transmit information about the delay certificate to the mobile terminal 20c based on the information about the contact information.

[0083] The mobile terminal 20c has, as its functions, a display unit 207 and a display control unit 209. The display unit 207 and the display control unit 209 are configured with the same hardware and have the same functions as the display unit 207 and the display control unit 209 of the mobile terminal 20a according to the second embodiment. That is, the display unit 207 visually displays various information under the control of the display control unit 209. Furthermore, the display control unit 209 controls the display of the display unit 207 and causes the display unit 207 to display various information. Specifically, in the fourth embodiment, the display control unit 209 causes the display unit 207 to display information about the delay certificate transmitted from the delay certificate distribution unit 307 of the passenger support server 30c.

[0084] The display control unit 209 of the mobile terminal 20c, the delay certificate distribution unit 307 of the passenger support server 30c, and the delay notification information generation unit 601 of the traffic management system 60 described above are configured with a processor such as a CPU or DSP, and a storage element such as a memory. The processor executes arithmetic processing according to a predetermined program stored in the storage element, thereby realizing each of the above functions. The function of the display control unit 209 of the mobile terminal 20c may be realized by a passenger who wishes to receive the service according to the fourth embodiment installing a dedicated app on the mobile terminal 20c. In other words, it is possible to create a program or app for realizing each of the above functions and implement it in an information processing device such as a server or a mobile terminal. The program or app may be distributed via a network. Alternatively, a computer-readable recording medium in which such a program or app is stored may be provided. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like.

[0085] The configuration of the passenger support system 4 according to the fourth embodiment has been described above. Note that the configuration shown in Fig. 6 is merely one example of the configuration of the passenger support system 4, and the passenger support system 4 may be configured so as to realize each of the functions described above as a whole, and the specific configuration may be arbitrary. For example, the passenger support server 30c and the traffic management system 60 may be configured integrally, and each function of the passenger support server 30c may be implemented in the traffic management system 60.

[0086] (Information processing method in passenger support system) The processing procedure of the information processing method in the passenger support system 4 described above will be described with reference to Fig. 7. Fig. 7 is a flow diagram showing the processing procedure of the information processing method in the passenger support system 4 according to the fourth embodiment. Note that the details of each process shown in Fig. 7 have already been explained when explaining the configuration of the passenger support system 4 with reference to Fig. 6, so detailed explanations will be omitted here.

[0087] In the information processing method in the passenger support system 4 according to the fourth embodiment, first, delay notification information is generated in the traffic management system 60 (step S301). Next, the generated delay notification information is transmitted to the passenger support server 30c (step S303). The processes shown in steps S301 and S303 correspond to the processes executed by the delay notification information generating unit 603 of the traffic management system 60 described with reference to FIG. 6.

[0088] Next, the passenger support server 30c identifies the mobile terminal 20c to which the delay certificate is to be distributed based on the boarding information stored in the boarding information DB 301. Specifically, the boarding information DB 301 is referenced to identify the mobile terminal identification information associated with the train identification information included in the delay notification information (step S305). The mobile terminal 20c corresponding to the extracted mobile terminal identification information is to be distributed with the delay certificate.

[0089] Next, information about the delay certificate is transmitted to the mobile terminal 20c corresponding to the extracted mobile terminal identification information (step S307). The processes shown in steps S305 and S307 correspond to the processes executed by the delay certificate distribution unit 307 of the passenger support server 30c described with reference to FIG.

[0090] Next, information about the delay certificate is displayed on the mobile terminal 20c (step S309). That is, the delay certificate is notified to and displayed on the mobile terminal 20c of the passenger who was on the delayed train. The process shown in step S309 corresponds to the process executed by the display control unit 209 of the mobile terminal 20c described with reference to FIG. 6.

[0091] The processing procedure of the information processing method in the passenger support system 4 according to the fourth embodiment has been described above.

[0092] As described above, according to the passenger assistance system 4 of the fourth embodiment, when a delay occurs, information about a delay certificate is delivered to the mobile terminal 20c of a passenger who was on the train on which the delay occurred. At this time, if the passenger has applied for a service related to the passenger assistance system 4, for example by installing an app, the information about the delay certificate is automatically delivered to the passenger even if the passenger does not request the transmission of the delay certificate (for example, a so-called PUSH notification is sent). Therefore, the complicated procedure for obtaining a delay certificate is not necessary, and passenger convenience can be improved.

[0093] Embodiment 5. (Distribution of text data for in-car announcements) (Passenger Support System Configuration) A configuration of a passenger support system for realizing a service for distributing text data of in-car announcements will be described with reference to Fig. 8. Fig. 8 is a block diagram showing a configuration of a passenger support system for a service for distributing text data of in-car announcements according to the fifth embodiment.

[0094] Referring to FIG. 8, the passenger support system 5 (user support system 5) includes a mobile terminal 20d, a passenger support server 30d (corresponding to an information processing device in this disclosure), and an in-car broadcasting management system 70. The mobile terminal 20d is the same terminal as the mobile terminal 20 that transmits ride information to the passenger support server 30 in the ride information collecting system 1 shown in FIG. 1. The passenger support server 30d is the same device as the passenger support server 30 in the ride information collecting system 1 shown in FIG. 1. In FIG. 8, for the mobile terminal 20d and the passenger support server 30d, only functions for realizing the service according to the fifth embodiment are illustrated, and functional configurations different from those shown in FIG. 1 are illustrated, so that they are formally assigned different reference numerals. Although not illustrated, the mobile terminal 20d, the passenger support server 30d, and the in-car broadcasting management system 70 each have a communication device that communicates with an external device in a predetermined communication format. The mobile terminal 20d and the passenger support server 30d, and the passenger support server 30d and the in-car broadcast management system 70 are connected to each other via the communication device so as to be able to communicate with each other.

[0095] The mobile terminal 20d has, as its functions, an input unit 203, a request notification information generating unit 211, a display unit 207, and a display control unit 209.

[0096] The input unit 203 is configured with the same hardware as the input unit 203 of the mobile terminal 20a according to the second embodiment, and has the same functions. That is, the input unit 203 is an interface that accepts various operational inputs by passengers. In the fifth embodiment, when a passenger misses an in-car announcement and wants to check the contents later, the passenger inputs information (hereinafter, referred to as request information) indicating that the passenger desires delivery of text data of the in-car announcement. The request information includes at least information (hereinafter, referred to as language designation information) that designates the language of the text data to be delivered. The input unit 203 provides the input request information to the request notification information generating unit 211. Note that, as an example, the following will describe a case where a passenger on a train requests delivery of text data of an in-car announcement made during the ride. However, the fifth embodiment is not limited to such an example, and the passenger may request delivery of text data of an in-car announcement made during the ride after getting off the train.

[0097] The request notification information generating unit 211 generates request notification information for notifying the passenger support server 30d of a request for delivery of in-car broadcast text data by adding its own mobile terminal identification information to the request information provided by the input unit 203. The request notification information generating unit 211 transmits the generated request notification information to an in-car broadcast text data delivery unit 309 of the passenger support server 30d, which will be described later.

[0098] The display unit 207 and the display control unit 209 are configured with the same hardware as the display unit 207 and the display control unit 209 of the mobile terminal 20a according to the second embodiment, and have the same functions. That is, the display unit 207 visually displays various information under the control of the display control unit 209. Furthermore, the display control unit 209 controls the display of the display unit 207, and causes the display unit 207 to display various information. Specifically, in the fifth embodiment, the display control unit 209 causes the display unit 207 to display a guide when the request information is input from the input unit 203. At this time, when the input unit 203 is configured with a touch panel, the input unit 203 and the display unit 207 may be integrally configured as a display device with a touch sensor, and the display control unit 209 may cause the display unit 207 to display an input screen for the request information. Furthermore, the display control unit 209 causes the display unit 207 to display text data of the in-car broadcast distributed from an in-car broadcast text data distribution unit 309 of the passenger support server 30d described later.

[0099] The passenger support server 30d has, as its functions, a boarding information DB 301 and an in-car broadcast text data delivery unit 309. The boarding information DB 301 is the same as the boarding information DB 301 shown in Fig. 1, and stores the boarding information of passengers.

[0100] When the in-car broadcast text data distribution unit 309 receives the request notification information from the request notification information generation unit 211 of the mobile terminal 20d, it requests the in-car broadcast management system 70 to acquire the text data of the in-car broadcast. Specifically, the in-car broadcast text data distribution unit 309 refers to the boarding information DB 301 and acquires the train identification information associated with the mobile terminal identification information included in the received request notification information. The in-car broadcast text data distribution unit 309 then transmits the acquired train identification information and the language designation information included in the request notification information to the in-car broadcast text data distribution unit 707 of the in-car broadcast management system 70 described later, and requests acquisition of the text data of the in-car broadcast made in the train corresponding to the train identification information (i.e., the train identification information indicating the train on which the passenger carrying the mobile terminal 20d who has requested the distribution of the in-car broadcast text data is riding).

[0101] Furthermore, the in-car broadcast text data distribution unit 309 receives the text data of the in-car broadcast that it has requested to acquire from the in-car broadcast management system 70. Then, it transmits the text data of the in-car broadcast to the display control unit 209 of the mobile terminal 20d that has transmitted the request notification information. As a result, as described above, the requested text data of the in-car broadcast is displayed on the display unit 207 of the mobile terminal 20d under the control of the display control unit 209.

[0102] The in-car broadcast text data delivery unit 309 may acquire the contact information (e.g., a telephone number, an email address, etc.) of the mobile terminal 20d by inquiring of the carrier of the mobile terminal 20d based on the mobile terminal identification information (e.g., a MAC address) transmitted from the mobile terminal 20d. Alternatively, if the mobile terminal identification information transmitted from the mobile terminal 20d includes information on the contact information as passenger attribute information, the in-car broadcast text data delivery unit 309 may transmit the in-car broadcast text data to the mobile terminal 20d based on the information on the contact information.

[0103] The in-car broadcasting management system 70 is a system owned by a railroad operator, and converts past in-car broadcasts into text data and manages them. The in-car broadcasting management system 70 has, as its functions, a voice translation unit 701, a translation unit 703, an in-car broadcast DB 705, and an in-car broadcast text data distribution unit 707.

[0104] Audio information related to the in-car announcement made by the crew is input to the audio translation unit 701 of the in-car announcement management system 70. For example, the in-car announcement equipment is configured so that when the audio information input from the in-car announcement microphone is transmitted to the speaker in the vehicle, it is also transmitted to the audio translation unit 701. The audio translation unit 701 translates the audio information and generates text data for the in-car announcement. Since various known voice recognition technologies may be used for the transcription process by the audio translation unit 701, detailed explanations thereof will be omitted here. For example, machine learning may be used for the transcription process. The audio translation unit 701 provides the generated text data to the translation unit 703 and the in-car announcement DB 705.

[0105] The translation unit 703 translates the text data generated by the speech translation unit 701 into another language. For example, when an in-car announcement is made in Japanese and the speech translation unit 701 generates text data in Japanese, the translation unit 703 translates the Japanese text data to generate text data in English, Chinese, Korean, or the like. The language into which the translation unit 703 translates may be appropriately set by the designer, provider, or the like of the passenger support system 5 according to the main nationalities, etc. of foreigners expected to use the route that is the target of the service according to the fifth embodiment. Since various known machine translation techniques may be used for the translation process by the translation unit 703, detailed explanations thereof will be omitted here. For example, machine learning may be used for the translation process. The translation unit 703 provides the generated text data in another language to the in-car announcement DB 705.

[0106] The in-car announcement DB705 is composed of a non-volatile storage device such as a HDD or a flash memory. The in-car announcement DB705 is a database in which text data of in-car announcements made during operation of each train is stored. The in-car announcement DB705 is provided with the text data of the in-car announcements generated by the voice translation unit 701 and the text data generated by the translation unit 703, which is translated into another language. The in-car announcement DB705 is also provided with train identification information from the operation management system. The in-car announcement DB705 stores the above text data in association with the train identification information. At this time, the in-car announcement DB705 also stores time information when the in-car announcement was made. The in-car announcement DB705 stores the text data whenever an in-car announcement is made in the train.

[0107] When the in-car broadcast text data distribution unit 707 receives the train identification information (i.e., the train identification information indicating the boarding history of the passenger who requested the distribution of the in-car broadcast text data) acquired from the boarding information DB 301 and the language designation information included in the request notification information from the in-car broadcast text data distribution unit 309 of the passenger support server 30d, it refers to the in-car broadcast DB 705 and acquires the in-car broadcast text data corresponding to the information. The corresponding in-car broadcast text data is the text data associated with the received train identification information (i.e., the text data of the in-car broadcast broadcast in the train corresponding to the received train identification information) and is the text data in the language corresponding to the received language designation information. At this time, the in-car broadcast text data distribution unit 707 identifies the time period during which the passenger carrying the mobile terminal 20d is aboard based on information about the date and time when the train identification information was distributed, which is included in the received train identification information, and acquires the in-car broadcast text data corresponding to the time period.

[0108] The in-car broadcast text data distribution unit 707 transmits the acquired in-car broadcast text data to the in-car broadcast text data distribution unit 309 of the passenger support server 30d. As described above, the in-car broadcast text data is transmitted to the mobile terminal 20d and displayed on the mobile terminal 20d. At this time, the in-car broadcast text data corresponding to the time period during which the passenger who owns the mobile terminal 20d is aboard is transmitted, so that the passenger who requested the distribution of the in-car broadcast text data can receive the text data of the in-car broadcast made while he or she is aboard.

[0109] The display control unit 209 and the request notification information generating unit 211 of the mobile terminal 20d, the in-car broadcast text data distribution unit 309 of the passenger support server 30d, and the in-car broadcast text data distribution unit 707 of the in-car broadcast management system 70 described above are configured by a processor such as a CPU or a DSP, and a storage element such as a memory. The processor executes arithmetic processing according to a predetermined program stored in the storage element, thereby realizing each of the above functions. The functions of the display control unit 209 and the request notification information generating unit 211 of the mobile terminal 20d may be realized by a passenger who wishes to receive the service according to the fifth embodiment installing a dedicated app on the mobile terminal 20d. In other words, a program or app for realizing each of the above functions can be created and implemented in an information processing device such as a server or a mobile terminal. The program or app may be distributed via a network. Alternatively, a computer-readable recording medium in which such a program or app is stored may be provided. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like.

[0110] The configuration of the passenger support system 5 according to the fifth embodiment has been described above. Note that the configuration shown in Fig. 8 is merely one example of the configuration of the passenger support system 5, and the passenger support system 5 may have any specific configuration as long as it is configured to realize each of the functions described above as a whole. For example, the passenger support server 30d and the in-car broadcasting management system 70 may be configured integrally, and each function of the passenger support server 30d may be implemented in the in-car broadcasting management system 70.

[0111] (Information processing method in passenger support system) The processing procedure of the information processing method in the passenger support system 5 described above will be described with reference to Fig. 9. Fig. 9 is a flow diagram showing the processing procedure of the information processing method in the passenger support system 5 according to the fifth embodiment. Note that the details of each process shown in Fig. 9 have already been explained when explaining the configuration of the passenger support system 5 with reference to Fig. 8, so detailed explanations will be omitted here.

[0112] In the information processing method in the passenger support system 5 according to the fifth embodiment, first, in the in-car broadcast management system 70, the in-car broadcast is translated into a voice, and the text data is stored in the in-car broadcast DB 705 in association with train identification information indicating the train in which the in-car broadcast was made (step S401). The text data of the in-car broadcast is translated into another language, and the translated text data is stored in the in-car broadcast DB 705 in association with train identification information indicating the train in which the in-car broadcast was made (step S403). The processes shown in steps S401 and S403 correspond to the processes executed by the voice translation unit 701 and the translation unit 703 of the in-car broadcast management system 70 described with reference to FIG. 8, respectively. Note that, for the sake of convenience, in FIG. 9, the processes shown in steps S401 and S403 are described as being executed once each before other processes, but in reality, the processes shown in steps S401 and S403 are executed at any time every time an in-car broadcast is made, regardless of other processes.

[0113] Next, the request information is acquired in the mobile terminal 20d (step S405). Next, the mobile terminal identification information is added to the acquired request information, thereby generating request notification information (step S407). Next, the generated request notification information is transmitted to the passenger support server 30d (step S409). The processes shown in steps S405 to S409 correspond to the processes executed by the request notification information generating unit 211 of the mobile terminal 20d described with reference to FIG. 8.

[0114] Next, the passenger support server 30d requests the in-car broadcasting management system 70 to acquire text data of the in-car broadcast based on the received request notification information. Specifically, the boarding information DB 301 is referenced to acquire train identification information associated with the mobile terminal identification information included in the request notification information (step S411). The acquired train identification information and the language designation information included in the request notification information are then transmitted to the in-car broadcasting management system 70 (step S413). The processes shown in steps S411 and S413 correspond to the processes executed by the in-car broadcasting text data distribution unit 309 of the passenger support server 30d described with reference to FIG. 8.

[0115] Next, the in-car broadcast management system 70 refers to the in-car broadcast DB 705 and acquires in-car broadcast text data corresponding to the received train identification information and language designation information (step S415). At this time, based on the date and time information at which the train identification information included in the received train identification information was distributed, the time period during which the passenger carrying the mobile terminal 20d is on board is identified, and the in-car broadcast text data corresponding to that time period is acquired. Next, the acquired in-car broadcast text data is transmitted to the passenger support server 30d (step S417). The processes shown in steps S415 and S417 correspond to the processes executed by the in-car broadcast text data distribution unit 707 of the in-car broadcast management system 70 described with reference to FIG. 8.

[0116] Next, the passenger support server 30a transmits the received in-car broadcast text data to the mobile terminal 20d (step S419). The process shown in step S419 corresponds to the process executed by the in-car broadcast text data delivery unit 309 of the passenger support server 30d described with reference to FIG.

[0117] Next, the text data of the received in-car announcement is displayed on the mobile terminal 20d (step S421). The process shown in step S421 corresponds to the process executed by the display control unit 209 of the mobile terminal 20d described with reference to FIG.

[0118] The processing procedure of the information processing method according to the fifth embodiment has been described above.

[0119] As described above, according to the passenger support system 5 of the fifth embodiment, text data of in-car announcements made during the ride is delivered to passengers who have requested the delivery of the text data of the in-car announcements. At this time, the passenger only needs to input the request information, and does not need to specify the train they are riding on. Therefore, for example, if a passenger misses an in-car announcement, the passenger can obtain the text data of the in-car announcement made on the train they are riding on through a simple procedure. In addition, since passengers can also obtain text data translated into other languages, the service related to the passenger support system 5 is also useful for overseas travelers who are not accustomed to hearing Japanese audio, for example.

[0120] In the above-mentioned configuration example, the in-car broadcasting management system 70 identifies the time period during which the passenger is aboard, and distributes text data of in-car broadcasts made during that time period. However, there may be cases where the passenger wants to check a specific in-car broadcast during that time period. In such a case, if text data of all in-car broadcasts during that time period is distributed, the passenger will have to search for the desired text data from among them, which may be cumbersome. Therefore, when the passenger inputs the request information, the passenger may be able to specify the text data of the in-car broadcast to be distributed. For example, in the in-car broadcasting management system 70, the text data of the in-car broadcast may be stored in association with the station names before and after the point where the in-car broadcast was made, the time when the in-car broadcast was made, and / or the type of the in-car broadcast (in-car broadcast regarding information on the next station (arrival time, transfer, etc.), in-car broadcast regarding a delay, etc.), and the display control unit 209 in the mobile terminal 20d may display a screen on the display unit 207 to input these items as a guide for inputting the request information. That is, the request information may include information about these input items (i.e., information specifying text data of a specific in-car broadcast). This allows the in-car broadcast text data distribution unit 309 of the passenger support server 30d to obtain the text data of the specified in-car broadcast from the in-car broadcast management system 70 based on the information specifying the text data of the specific in-car broadcast included in the request information, and distribute it to the mobile terminal 20d, so that the passenger can receive only the text data he or she desires. In this way, passengers can specify text data of a specific in-car broadcast when inputting request information, thereby further improving passenger convenience.

[0121] In the above-mentioned configuration example, the passenger assistance system 5 is configured such that the text data of the in-car announcement translated into other languages ​​is managed in the in-car announcement management system 70 and the text data in multiple languages ​​can be distributed, but the configuration of the passenger assistance system 5 is not limited to this example. The passenger assistance system 5 may be configured such that only the text data in the language in which the in-car announcement is made is managed in the in-car announcement management system 70 and only the text data related to the language can be distributed. According to this configuration, the function of the translation unit 703 is not required, so that the in-car announcement management system 70 can be configured more simply and the costs associated with building and operating the in-car announcement management system 70 can be reduced. However, considering the convenience of travelers from overseas, it is preferable to configure the passenger assistance system 5 so that the text data in multiple languages ​​can be distributed, as in the above-mentioned configuration example.

[0122] (Modifications, supplements, etc.) Although the preferred embodiment of the present disclosure has been described in detail above with reference to the attached drawings, the technology according to the present disclosure is not limited to such examples. It is clear that a person having ordinary knowledge in the technical field to which the present disclosure belongs can conceive of various modified examples within the scope of the technical ideas described in the claims, and it is understood that these also naturally belong to the technical scope of the present disclosure. For example, the technology according to the present disclosure can take the following forms in addition to the above-described embodiments.

[0123] For example, in the above-described first embodiment, the train identification information is configured to include information for identifying the train and the cars constituting the train, but the present disclosure is not limited to such an example. For example, when a plurality of information distribution devices 10 are installed in the vehicle 101, the train identification information may further include information for identifying the installation positions of the information distribution devices 10 in the vehicle 101. In this case, the train identification information further includes information for identifying an area in the vehicle 101 (i.e., an area corresponding to an area in which the information distribution device 10 can distribute the train identification information). In other words, by using the boarding information including the train identification information, it becomes possible to know in which area in the vehicle 101 the passenger, who is the holder of the mobile terminal 20, is / was riding.

[0124] When such riding information is used, when identifying the vehicle 101 in which the passenger who reported the lost property was riding in the second embodiment, it is possible to identify the area in the vehicle 101 in which the passenger was riding. Therefore, the location where the lost property is thought to have been left behind is identified in more detail, so that the lost property management system 40 can perform inquiries with higher accuracy. Similarly, when such riding information is used, when identifying the vehicle 101 in which the infected person was riding in the third embodiment, it is possible to identify the area in the vehicle 101 in which the infected person was riding. In addition, when identifying passengers who were riding in the same vehicle 101 as the infected person, it is possible to identify not only whether they were riding in the same vehicle 101, but also whether they were riding near the infected person in the vehicle 101. Therefore, when notifying that they were riding in the same vehicle as the infected person, it is possible to provide a more detailed notification including information about the distance from the infected person.

[0125] Also, for example, in the above-mentioned third and fourth embodiments, the passenger-sharing notification and information on the delay certificate are automatically delivered to the passengers by so-called PUSH notification, but the present disclosure is not limited to such examples. For example, in the third embodiment, when a request (inquiry) is received from a passenger, the passenger support server 30c may identify the train on which the passenger was riding based on the boarding information, and further determine whether or not an infected person was riding on the train based on the boarding information, and if it is determined that the passenger was riding on the train, the passenger-sharing notification may be delivered to the passenger who made the request. Similarly, for example, in the fourth embodiment, when a request is received from a passenger, the passenger support server 30c may determine whether or not the passenger is riding on / had been riding on a train for which a delay certificate is issued based on the boarding information, and if it is determined that the passenger is eligible for issuance, information on the delay certificate may be delivered to the passenger.

[0126] Moreover, the services according to the second to fifth embodiments described above may be provided to passengers individually, or two or more of these services may be provided simultaneously. When a plurality of services according to the second to fifth embodiments are provided to passengers, these services may be provided by installing an app that realizes the group of services to be provided in an integrated manner on a mobile terminal carried by the passenger. This eliminates the need for passengers to install apps related to each service, and passengers only need to install the apps once, making it possible to enjoy the services without performing cumbersome tasks. Furthermore, when or after installing apps for providing some or all of the services according to the second to fifth embodiments on a mobile terminal, passengers may be able to select the services they wish to receive from the apps. This makes it possible for passengers to enjoy only the services they desire.
