It should be noted that, in the embodiments, the components denoted by the same reference numerals perform the same operation, and thus the repeated description may be omitted.

FIG. 1 is a conceptual diagram of the information processing system in this embodiment. 1A shows an example of the configuration of the information processing system, and FIG. 1B shows a terminal device 3 and trains A, B,... For a series of stations a1, a2,. An example of the positional relationship of is shown.

This information processing system includes one or more information processing devices 1, a server device 2, and one or more terminal devices 3.

The information processing device 1 is installed in a train, for example, and is connected to the server device 2 via the Internet. The terminal device 3 is installed in a station or carried by each passenger and is connected to the server device 2 via the Internet. However, the information processing device 1 may be installed in, for example , a bus , and may be installed as long as it is a vehicle for public transportation.

Generally, the information processing device 1, the server device 2, and the terminal device 3 installed at a station can be realized by dedicated computers or general-purpose computers such as a computer system 900 described later. The terminal device 3 carried by a passenger is, for example, a mobile terminal such as a smartphone, a tablet, or a mobile PC. However, implementation means and types of each device are not limited.

The information processing apparatus 1, and the terminal device 3 carried by a passenger, for example, by using a position detecting function of the GPS receiver or radio communications networks, it is possible to obtain position information about the device itself. The terminal device 3 installed in the station stores, for example, position information regarding the station.

A train generally refers to a vehicle or a train of vehicles traveling on a track such as a railroad. The train referred to in the present embodiment is, for example, a public transport train such as a train, subway, or monorail. Similarly, a bus is a public transportation bus that operates on certain routes.

In the example of FIG. 1A, the information processing device 1 is installed in a train A including a plurality of vehicles A1, A2,.... The same information processing device 1 is installed in the train B and the like. Here, “A”, “B” and the like are train identifiers (hereinafter sometimes referred to as “train ID”) that identify each train, and “A1”, “A2”,... Is a vehicle identifier (hereinafter sometimes referred to as “vehicle ID”) for identifying each vehicle. In the case of a one-car train, the vehicle ID may be the same as the "train ID". Each ID is, for example, a serial number such as “1”, “2”, “3”,... Or a unique array composed of numbers/symbols selected according to a predetermined rule (or randomly). Used.

The vehicle A1 has one or more (two in this case) entrances/exits, and sensors s1 for detecting a passenger getting in and out of the vehicle A1 at or near each entrance. s2 is provided. The vehicle A2 also has two entrances and exits, and similar sensors s3 and s4 are provided at or near each entrance and exit. The following vehicles A3, A4,... Have the same configuration.

Preferably, a sensor s5 for detecting movement of a person between the vehicles is further provided at one of the pair of through-holes (here, the through-hole on the vehicle A1 side) facing each other with the connecting portion between the two vehicles A1 and A2 sandwiched therebetween. It is provided. Similarly, a sensor s6 for detecting movement of a person between the vehicles is further provided at one of the pair of through-holes (here, the through-hole on the vehicle A2 side) facing each other with the connecting portion between the two vehicles A2 and A3 sandwiched therebetween. It may be provided, or a similar sensor may be provided between the two vehicles following it.

Each of the sensors s1, s2,... Is usually an infrared sensor (or laser sensor), an image sensor (for example, CCD, CMOS, etc.), or the like. In the case of the infrared sensor, for example, by using a plurality of sensor elements, it is possible to determine the moving direction (passing/alighting) of the passenger based on the deviation of the detection timing by each sensor element. In the case of an image sensor, for example, by extracting a characteristic image of a person (for example, a facial image) in a frame and comparing the positions of the characteristic images between frames, the same image processing is performed to detect the movement of the person. Can be distinguished. However, any type of sensor can be used as long as it can detect passengers getting on and off and movement.

Next, an outline of the operation of the information processing system configured as above will be described.

The information processing device 1 acquires, for example, the passenger count related information relating to the passenger count of the vehicles A1, A2,... With the sensors s1, s2,.

The passenger number related information is usually transmitted in pairs with vehicle IDs (A1, A2,...) Which identify the vehicles A1, A2,. When there is a single vehicle, the transmission of the vehicle ID may be omitted.

The number of passengers of the vehicles A1, A2,... Is the number of passengers of the entire vehicles A1, A2,... That is, the number of passengers of the train A, or the number of passengers of each vehicle A1, A2,.

The information relating to the number of passengers is calculated, for example, based on the number of passengers and the number of passengers getting off at each station. Preferably, based on the number of passengers on each vehicle A1, A2,... And the number of passengers getting off from each vehicle A1, A2,..., And the number of passengers moving between the vehicles A1, A2,. Passenger number related information is calculated for each.

Therefore, the timing at which the information processing device 1 acquires the passenger count related information is during the period when the train is stopped at the station (or from the opening and closing of the entrance/exit gate), and the timing of transmitting the passenger count related information. Is usually when the train leaves the station (or when the boarding gate is closed) or later.

The server device 2 receives and stores the pair of vehicle ID and passenger number related information transmitted by each information processing device 1, and transmits the passenger number related information in response to the inquiry including the vehicle ID from the terminal device 3. To do.

The terminal device 3 transmits an inquiry including the vehicle ID to the server device 2 and receives the passenger count related information.

The vehicle ID is acquired, for example, from the search result of the timetable search. The timetable search is a search regarding a diagram (scheduled operation) of a train or a bus, such as route search and transfer guidance.

In the timetable search, inputs such as departure station, arrival station, time (departure time or arrival time) are generally accepted, and as a search result, multiple trains operating between the departure station and the departure station at or around the time. You can get schedule information about buses and buses. The operation schedule information includes, for example, a train ID, one or more vehicle IDs, arrival times, transfer times, and the like. However, the form of the timetable search and the content of the search result are not limited to this.

The terminal device 3 normally receives the passenger count related information at a predetermined timing.

The timing at which the terminal device 3 receives the information relating to the number of passengers is, for example, a series of stations along the track between the terminal device 3 and the trains A, B,... (Station IDs for identifying each station are “a1”, “a2”). It is decided by what kind of positional relationship there is with respect to ",...".

For example, as shown in FIG. 1B, when the terminal device 3 is located at the station a3 and trains A, B,... Travel from the station a1 toward the station a3, the number of passengers of the train A is related. The timing at which the information is received by the terminal device 3 is typically when the train A leaves the previous station 2a. However, it is not limited to this as long as the train A arrives at the station.

In order to receive the passenger number related information when the train A departs from the previous station 2a, for example, the terminal device 3 itself sends an inquiry including the train ID “A” to the server device 2 at a predetermined timing. It suffices to transmit and receive the passenger number related information of the train A (terminal-initiated, that is, pull type). The predetermined timing in this case is, for example, an appropriate timing (for example, at the arrival station) within the period in which the train A is stopping at the previous station a2. However, it may be an appropriate timing before arriving at the previous station 2a.

Alternatively, the information regarding the number of passengers of the train A transmitted (broadcast) by the server device 2 at a predetermined timing may be received (server initiative, that is, push type). The predetermined timing in this case is usually the timing when the train A leaves the previous station a2, but if the train A that left the previous station a2 arrives at the station, Not exclusively. This allows you to know the status of the next train.

The terminal device 3 outputs the vacant vehicle information regarding the vacant vehicle based on the received passenger count related information. The vacant vehicle information will be described later.

In addition, the terminal device 3 acquires the arrival time or the transfer time from the search result of the timetable search, and further outputs a reminder at a timing related to the acquired time.

The timing related to the time is just that time or an appropriate timing before that time (for example, a predetermined time such as one minute before the arrival or when the train departs from the previous station).

Next, each element which comprises this information processing system is demonstrated.

FIG. 2 is a block diagram of the information processing device 1 according to the present embodiment. The information processing device 1 includes a storage unit 11, a processing unit 12, and a transmission unit 13. The processing unit 12 includes an acquisition unit 121.

The storage unit 11 stores, for example, an identifier (for example, an IP address or a MAC address) for identifying the information processing device 1 itself, and a train ID (for example, the information for identifying the train on which the information processing device 1 is mounted. When the processing device 1 is installed in the train A, the train ID “A”) and the like are stored.

Further, the storage unit 11 has a correspondence relationship between the sensors and the vehicles, for example, a correspondence relationship between the sensors s1, s2,... And the vehicles A1, A2,. The sensor/vehicle correspondence information indicating whether it is provided) is stored. The sensor/vehicle correspondence information is, for example, a set of a pair of a sensor ID and a vehicle ID. The pair of sensor ID and vehicle ID is, for example, “s1” and “A1”, “s2” and “A1”, “s3” and “A2”, and “s4”. Pair with “A2”, and so on.

Further, the storage unit 11 stores operation schedule information regarding a train or the like on which the information processing device 1 is mounted. For example, the storage unit 11 of the information processing device 1 mounted on the train A stores operation schedule information regarding the operation of the train A. This operation schedule information includes, for example, the vehicle ID (“A”) of the train A, the station IDs (“a1”, “a2”,...) Of the stations a1, a2,... At which the train A stops, and the stations a1, a2. , Information about arrival times at stations, departure times from each station a1, a2,...

Further, the storage unit 11 also stores position information of each station where the train or the like stops, for example, position information of each station a1, a2,... Shown in FIG. The position information is, for example, a set of pairs of station IDs (“a1”, “a2”,...) And position information (x1, y1,), (x2, y2),. The position information is usually position coordinates such as latitude and longitude, but any kind of information may be used as long as it is information indicating the position of a station.

The processing unit 12 performs acquisition of various information, determination processing regarding acquisition timing of various information, and the like.

The acquisition unit 121 acquires the train ID and the sensor/vehicle correspondence information from the server device 2, and stores the sensor/vehicle correspondence information in the storage unit 11.

The acquisition unit 121 also acquires train operation schedule information and stop station position information from the server device 2, and stores the train operation schedule information and stop station position information in the storage unit 11. Note that the acquisition timing is usually before the start of operation of the train, but is not limited to this as long as it is an appropriate timing.

In addition, the acquisition unit 121 acquires the passenger number related information regarding the number of passengers of the vehicle by the sensor. Note that the sensor may or may not be included in the acquisition unit 121.

Preferably, the acquisition unit 121 calculates the passenger count related information based on the number of passengers in the vehicle (for example, the vehicle A1) at each station (for example, the stations a1, a2,...) And the number of passengers getting off from the vehicle. Therefore, the acquisition timing of the passenger number related information is usually the period from the arrival of the train at each station to the departure of the station.

When the above-mentioned vehicles are a plurality of vehicles (for example, vehicles A1, A2, ...) which constitute one train (for example, train A), acquisition part 121 has each vehicle at each station (for example, stations a1, a2, ...). Based on the number of passengers to and from each vehicle, and the number of passengers moving between vehicles, passenger-number-related information is calculated for each of a plurality of vehicles constituting one train.

However, the number of people moving between vehicles need not be acquired. That is, the acquisition unit 121 may calculate the passenger count related information for each of a plurality of vehicles constituting one train, based on the number of passengers in each vehicle at each station and the number of passengers getting off from each vehicle.

The transmission unit 13 transmits the passenger count related information acquired by the acquisition unit 121 to the server device 2. When the passenger number related information is the passenger number related information regarding the number of passengers for each vehicle, the transmission unit 13 transmits the passenger number related information in pairs with the vehicle ID that identifies each vehicle. The transmission timing of the passenger number related information is usually when the train leaves the station, but may be later than this.

Similar operation schedule information is stored for the train B and other trains. The server storage unit 21 also stores a set of pairs of vehicle IDs and passenger number related information, which will be described later.

The server reception unit 22 receives the pair of the vehicle ID and the passenger count related information transmitted by the transmission unit 13 of the information processing device 1.

The server processing unit 23 performs processing such as accumulating the received information in the server storage unit 21.

The server storage unit 231 stores the pair of the vehicle ID and the passenger count related information received by the server reception unit 22 in the server storage unit 21.

In response to the inquiry including the vehicle ID from the terminal device 3, the server transmission unit 24 transmits the passenger number related information paired with the vehicle ID (terminal initiative). More specifically, the inquiry from the terminal device 3 includes, in addition to the vehicle ID, a terminal ID for identifying the terminal device 3, and the server transmission unit 24 determines that the number of passengers paired with the vehicle ID. The related information is acquired from the server storage unit 21, and the acquired passenger number related information is transmitted to the terminal device 3 corresponding to the terminal ID.

Alternatively, the server transmission unit 24 may transmit the passenger count related information at a predetermined timing (server initiative). The predetermined timing is usually when the train leaves the station or when the door of the entrance/exit is closed. For example, as described above, when the train leaves the station, when the pair of the vehicle ID and the passenger count related information is transmitted by the transmitter 13 of the information processing device 1 mounted on the train, Immediately after the terminal receiving unit 33 receives the pair with the passenger number related information, the server transmitting unit 24 may multicast the received pair of the vehicle ID and the passenger number related information to each terminal device 3. ..

Specifically, the terminal reception unit 32 receives an execution instruction regarding the input of the arrival station and the inquiry about the vacant vehicle. In response to this, the terminal processing unit 34 first sets the arrival station, then detects the current position using, for example, the position detection function of the GPS receiver or the wireless communication network, and sets the detected current position. The corresponding station is set as the departure station, and the current time is set as the departure time. The departure station and the departure time may be input by the user in addition to the arrival station.

The terminal search unit 341 transmits a request for the operation schedule information corresponding to the input or set destination station to the external device such as the server device 2 via the terminal transmission unit 36, and the operation via the terminal reception unit 33. Receive appointment information. The terminal search unit 341 performs a timetable search using the received operation schedule information, so that the search results regarding the plurality of trains and buses operating between the departure and arrival stations at the time or before and after the time are displayed. can get.

The search results include, for example, train IDs related to one or more trains that are options when the user selects a train to be boarded, vehicle IDs related to one or more trains forming the train, arrival times, transfer times, and the like. Has been. However, the procedure of the timetable search and the content of the search result are not limited to this.

The terminal acquisition unit 342 acquires the vehicle ID from the search result by the terminal search unit 341. Specifically, for example, each vehicle that constitutes the next train (a train having a departure time closest to the input time; also referred to as a "next train. In the example of FIG. 1B, a train A)" Vehicle ID (for example, “A1”, “A2”,...) Of In addition to this, the train ID (for example, “B”) of the next train (also referred to as “one train after another. Train B in the example of FIG. 1B”) may be further acquired. Further, train IDs after the trains may be acquired one after another.

(Step S501) The acquisition unit 121 of the information processing device 1 acquires the operation information of the train A and the position information of the stop station from the server device 2 before starting the operation of the train (for example, the train A), and stores it in the storage unit 11. Store.

(Step S502) The processing unit 12 sets an initial value 1 to a variable i indicating which stop station the next station is. Note that the starting station is the first stop station.

(Step S503) The processing unit 12 determines whether or not the train A equipped with the information processing device 1 has arrived at the i-th station. Specifically, for example, the acquisition unit 121 acquires the current time from, for example, the MPU or the like that configures the processing unit 12, and further acquires the position information of the train A using a GPS receiver or the like. The processing unit 12 uses the current time and position information acquired by the acquisition unit 121, and the position information of each station a1, a2,... It may be determined whether A arrives at the i-th station. When the train A arrives at the i-th station, the process proceeds to step S503, and when it does not arrive, the same determination is repeated.

(Step S504) The acquisition unit 121 obtains passenger number related information (Fi) regarding the number of passengers (at the time of leaving the i-th station) of each of the vehicles A1, A2,... , Are acquired (hereinafter, this process may be referred to as “passenger number related information (Fi) acquisition process”).

FIG. 6 is a flowchart regarding details of a partial operation (passenger number related information (Fi) acquisition processing) of the information processing device 1 according to the present embodiment.

(Step S601) The acquisition unit 121 acquires the station ID (for example, “ai”) of the i-th station from the operation schedule information or the like stored in the storage unit 11, for example.

(Step S602) Based on the signals from the sensors s1, s2,..., The acquisition unit 121 determines whether or not any of the sensors has detected the passage of a person. Specifically, for example, each sensor s1, s2,... Shows "0" when the passage of a person is not detected, and changes from "0" to "1" when the passage of a person is detected. If such a signal is output, and the signal from any of the sensors indicates “1”, the acquisition unit 121 can determine that the sensor has detected the passage of a person. If any sensor detects the passage of a person, the process proceeds to step S603, and if not, the process proceeds to step S607.

(Step S603) The acquisition unit 121 acquires the vehicle ID (for example, “Aj”) corresponding to the ID of the sensor from the sensor/vehicle correspondence information stored in the storage unit 11. For example, when the sensor, that is, the sensor that detects the movement of a person is the sensor s2, the vehicle ID “A1” associated with the sensor ID “s2” is acquired.

(Step S604) The acquisition unit 121 determines whether or not the passage of a person detected by the sensor in step S602 is due to a boarding. Specifically, for example, if each of the sensors s1, s2,... Is an infrared sensor having a plurality of sensor elements, the moving direction of the person, that is, getting on or off, is determined based on the time difference between the signals from each sensor element. Can be determined. Further, if each of the sensors s1, s2,... Is an image sensor, the same determination can be performed by image processing. If the detected passage of the person is due to the boarding, the process proceeds to step S605. If not, the process proceeds to step S605.

(Step S605) The acquisition unit 121 counts up (also referred to as increment) the number of passengers (eg, Pij) in the vehicle Aj at the station ai. For example, when the vehicle ID “A1” is acquired in step S603 and it is determined in step S604 that the vehicle is a passenger, the number of passengers Pi1 who board the vehicle A1 at the station ai is counted up. Then, it returns to step S602.

(Step S606) The acquisition unit 121 counts up the number of people (eg, Qij) getting off the vehicle Aj. For example, when the vehicle ID “A1” is acquired in step S603 and it is determined in step S604 that the vehicle is not a passenger, the number of passengers Qi1 getting off from the vehicle A1 at the station ai is counted up. Then, it returns to step S602.

(Step S607) The acquisition unit 121 determines whether or not the train A departs from the station ai. Whether or not the vehicle has started can be determined in the same manner as the determination as to whether or not the vehicle has arrived in step S503 described above. If the train A has departed from the station ai, the process proceeds to step S608, and if not, the process returns to step S602.

(Step S608) In general (except when i=1), the acquisition unit 121 generally has information on the number of passengers at the time of departure from the previous station (for example, the station a(i-1) immediately before the station ai) ( Vehicles at the time of departure from station ai based on F(i-1)) and the number of passengers and the number of passengers aboard each vehicle A1, A2,... At station ai (for example, Pi1 and Qi1, Pi2 and Qi2,... ). Calculate the number of passengers for each (Ri1, Ri2,... ). The passenger number related information (F(i-1)) at the time of departure from the front station a(i-1) is acquired from the storage unit 11.

For example, the number of passengers Ri1 of the vehicle A1 at the time of departure from the station ai is greater than the number of passengers R(i-1)1 of the vehicle A1 at the time of departure from the previous station a(i-1) to the vehicle A1 at the station ai. It can be obtained by adding the number of persons Pi1 and subtracting the number of getting-off persons Qi1 from the vehicle A1 at the station ai. Similarly, the number of passengers Ri2 of the vehicle A2 is obtained by adding the number of passengers Pi2 to the number of passengers R(i-1)2 and subtracting the number of passengers getting off Qi2.

In the case of i=1, there is no "previous station a0" or "passenger number related information F0" at the station a0, but for convenience, the number of passengers may be calculated as R01=R02,.

That is, the passenger count related information F1 at the time of departure from the station a1 is calculated based on the number of passengers and the number of passengers aboard each vehicle A1, A2,... At the station a1 (for example, P11 and Q11, P12 and Q12,... ). It

(Step S609) The acquisition unit 121 configures the passenger count related information Fi at the time of departure from the station ai by associating the ID “ai” of the station ai with the passenger counts Ri1, Ri2,... For each vehicle obtained in step S608. To do. The configured passenger count related information Fi is accumulated in the storage unit 11 by the processing unit 12, for example, and is used when configuring the next passenger count related information F(i+1). Further, the acquisition unit 121 may total the number of passengers Ri1, Ri2,... For each vehicle, and may include the total number of passengers, that is, the total number of passengers of the train A in the passenger number related information Fi.

In the above flow, the number of passengers Pij boarded up is counted up in step S605, and the number of passengers Qij boarded down is counted up in step S606. Instead of individually counting up the two variables Pij and Qij in this way, for example, one variable is used. The number of passengers Rij may be counted up in step S605, but may be counted down in step S606.

Then, it returns to the flowchart of FIG.

(Step S505) The transmission unit 13 transmits the passenger count related information Fi acquired by the acquisition unit 121 to the server device 2.

FIG. 10 is a data structure diagram regarding the passenger count related information Fi transmitted by the transmission unit 13. (A) shows the passenger number related information F2 for each vehicle A1, A2... When leaving the station a2, and (B) shows the passenger number related information F1 for each vehicle B1, B2,... When leaving the station a1. An example is shown.

The passenger number related information Fi is, for example, a station ID “ai”, one or more vehicle IDs “A1”, “A2”,... Corresponding to the station ID, and one or more corresponding to each of the one or more vehicle IDs. And the number of passengers Ri1, Ri2,.

The passenger number related information Fi may further include the total number of passengers that is the total number of passengers R1, R2,... For each vehicle, that is, the total number of passengers of the train A, and corresponds to each of one or more vehicle IDs. It may include one or more passengers, and one or more passengers corresponding to each vehicle ID.

In the present embodiment, the pair of the station ID “ai”, the one or more vehicle IDs “A1”, “A2”,... And the one or more passengers is called the passenger count related information Fi. , The number of passengers associated with one vehicle ID may be referred to as passenger number related information. In that case, the transmission unit 13 associates a set of vehicle ID and passenger number related information with the station ID. Will be sent.

(Step S506) The processing unit 12 increments the variable i.

(Step S507) The processing unit 12 determines whether or not the i-th station is the terminal station of the train A based on the operation schedule information stored in the storage unit 11. If the i-th station is the terminal station of the train A, the operation is terminated, and if it is not the terminal station, the process returns to step S503.

FIG. 7 is a flowchart for explaining the operation of server device 2 in the present embodiment.

(Step S701) The server processing unit 23 determines whether or not a predetermined end event (for example, a power-off operation, interruption of another process, etc.) has occurred. If the end event has occurred, the operation is terminated, and if not, the process proceeds to step S702.

(Step S702) The server processing unit 23 determines whether or not the server receiving unit 22 has received the passenger number related information Fi (or the station ID and a set of a pair of the vehicle ID and the passenger number related information associated therewith). Determine whether. If the server reception unit 22 receives the passenger count related information Fi, the process proceeds to step S703, and if not, the process proceeds to step 704.

(Step S703) The server storage unit 231 receives the passenger count related information Fi (or the station ID and the set of a pair of the vehicle ID and the passenger count related information associated with the station ID) received by the server reception unit 22, for example. The data is stored in the server storage unit 21 in the manner as shown in FIG.

FIG. 11 is a data structure diagram related to the passenger count related information accumulated in the server storage unit 21. The passenger number related information accumulated in the server storage unit 21 includes a vehicle ID, one or more station IDs corresponding to the vehicle ID, and one or more passenger numbers corresponding to each of the one or more station IDs. The passenger number related information accumulated in the server storage unit 21 may further include, for example, the total number of passengers of each train A, B,... (The total number of passengers of each car), or one or more stations. It may include one or more passengers for each ID, and one or more passengers for each station ID. In that case, as for the total number of passengers, the information processing device 1 may calculate the total number of passengers of each vehicle and transmit the total number of passengers to the terminal device 3, or the terminal device 3 may receive each vehicle from the information processing device 1. You may add up the number of passengers. Then, it returns to step S701.

(Step S704) The server processing unit 23 determines whether the server receiving unit 22 has received an inquiry including the vehicle ID. When the server receiving unit 22 receives the inquiry, the process proceeds to step S705, and when not received, the process returns to step S701.

(Step S705) The server transmission unit 24 acquires the passenger count related information corresponding to the vehicle ID from the server storage unit 21 and transmits it to the terminal device 3 which is the transmission source of the inquiry. The inquiry from the terminal device 3 further includes, in addition to the vehicle ID, a terminal ID for identifying the terminal device 3 itself, and the passenger count related information is transmitted to the terminal device 3 corresponding to the terminal ID. It Then, it returns to step S701. For example, in response to an inquiry including the vehicle IDs "A1", "A2",..., Of the passenger number related information shown in FIG. 11, the portion corresponding to the vehicle IDs "A1", "A2",. To be done. In addition to this, the part corresponding to the train ID “A” (all vehicles) may also be transmitted. However, of the passenger number related information corresponding to the vehicle IDs “A1”, “A2”,... (And the train ID “A”), the portion corresponding to the station ID of the station that has already passed is excluded from the transmission target. Good.

FIG. 8 is a flowchart for explaining the operation of terminal device 3 in the present embodiment.

(Step S801) The terminal processing unit 34 determines whether or not the terminal receiving unit 32 has received an inquiry about an empty vehicle. If the terminal accepting unit 32 accepts the inquiry about the vacant vehicle, the process proceeds to step S802, and if not, the same determination is repeated.

The terminal reception unit 32 receives, for example, an input of a destination station (destination station) and an execution instruction regarding an inquiry about an empty vehicle via an input device such as a keyboard or a touch panel. The terminal reception unit 32 may further receive the departure station, the departure time, the arrival time, and the like.

(Step S802) The terminal processing unit 34 acquires position information indicating the current position using a GPS receiver or the like, and acquires time information indicating the current position from the built-in MPU or the like.

(Step S803) The terminal acquisition unit 342 determines, for example, that the station corresponding to the acquired position information is the departure station and the current time indicated by the time information is the departure time, the departure station, the departure time, and the terminal reception unit 32. A timetable search is carried out based on the arrival station received. In the timetable search, for example, operation schedule information regarding a plurality of trains operating between the departure and arrival stations at or around the time indicated by the time information is acquired from the server device 2. Then, based on the acquired operation schedule information, the train IDs of a plurality of trains that are options, the vehicle IDs of one or more vehicles that configure each train, the arrival time of each train at the arrival station, and the one train The train station, train transfer time, etc. are searched.

(Step S804) The terminal acquisition unit 342 determines the vehicle ID (for example, the vehicle ID “A1”, “A2”,... Of the next train A, the vehicle ID “B1”, “of the next train B” from the result of the timetable search. B2″,... Etc.) are acquired. Alternatively, for example, the terminal output unit 35 outputs the identification information of the plurality of trains A, B,... Which are options via an output unit such as a display or a speaker, and the terminal reception unit 32 outputs the plurality of trains A, B. The terminal acquisition unit 342 may acquire the vehicle ID of the selected train by accepting an operation of selecting one of the selected trains.

(Step S805) The terminal transmission unit 36 transmits an inquiry including the vehicle ID acquired by the terminal acquisition unit 342 to the server device 2.

(Step S806) The terminal processing unit 34 determines whether or not the terminal receiving unit 33 has received the passenger count related information corresponding to the vehicle ID. When the terminal receiving unit 33 receives the passenger number related information corresponding to the vehicle ID, the process proceeds to step S807, and when not received, the same determination is repeated.

(Step S807) Based on the passenger count related information received by the terminal receiving unit 33, the terminal output unit 35 outputs vacant vehicle information regarding an vacant vehicle through an output device such as a display or a speaker.

(Step S808) For example, the terminal processing unit 34 determines whether or not the terminal receiving unit 32 has received a train selection via an input unit such as a keyboard or a touch panel. Alternatively, when the terminal device 3 is a mobile terminal such as a smartphone, the terminal processing unit 34 may determine whether or not the user got on the train based on the position information from the GPS receiver or the like. When the terminal reception unit 32 receives the selection of the train, or when the user gets on the train, the process proceeds to step S809, the terminal reception unit 32 does not receive the selection of the train, and the user has not boarded the train. In that case, the same determination is repeated.

(Step S809) The terminal acquisition unit 342 further acquires the time when the train arrives at the arrival station or the transfer station (arrival time or transfer time) from the result of the timetable search by the terminal search unit 341. For example, when the train A is selected or when the user gets on the train A, the time when the train A arrives at the arrival station or the transfer station is acquired from the operation schedule information of the train A included in the search result. It

(Step S810) The terminal processing unit 34 acquires position information indicating the current position and time information indicating the current position.

(Step S811) The terminal processing unit 34 determines whether or not the train (for example, the train A) is close enough to the arrival station or the transfer station so as to satisfy a predetermined condition. The predetermined condition is, for example, a condition regarding a distance, specifically, a condition such that “the distance between the train and the arrival station or the transfer station is less than (or less than) a threshold”, or a condition regarding time, Is a condition such as "the time until the train arrives at the arrival station or the transfer station is less than or equal to a threshold value (or less than the threshold value)". If the train is close enough to the arrival station or the transfer station to satisfy a predetermined condition, the process proceeds to step S812, and if not, the process returns to step S801.

(Step S812) The terminal output unit 35 is, for example, a bell sound or a song, or “Soon to arrive” or “Next station” at a timing related to the time (arrival time or transfer time) acquired by the terminal acquisition unit 342. Please switch to a fast train with "." The timing associated with the time of day is usually just at that time, or before that time (eg, a certain time before one minute before arrival, when the train departs from the previous station, etc.). Then, it returns to step S801.

Hereinafter, a specific operation example of the information processing system according to the present embodiment will be described. The following description is an example and does not limit the invention. In addition, the description of the above items may be omitted.

A conceptual diagram of the information processing system is shown in FIG. The terminal device 3 is a mobile terminal in this example, and is carried by a user.

It is assumed that the current time is 7:09, and the user is walking toward the platform of the station a3 where trains A, B,...

The schedule information of trains A, B,... Is shown in FIG. The next train A at station a3 departs at 7:14 and goes to XX, and is about to arrive at station a2, which is one station ahead. Train B, which is leaving one after another, is bound for XX at 7:19 and is running toward the station a1 two stations ahead.

When the train A arrives at the station a2, in the information processing device 1 mounted on the train A, the acquisition unit 121 detects the passenger count related information F2 regarding the passenger count of each vehicle A1, A2,... The process of acquiring by s1, s2,... Starts.

That is, the storage unit 11 stores, for example, operation schedule information regarding the train A, sensor/vehicle correspondence information, passenger number related information F1 regarding the number of passengers of each vehicle A1, A2,... At the time of departure from the station a1. First, the acquisition unit 121 acquires the ID “a2” of the station a2 from the operation schedule information.

Next, the acquisition unit 121 determines whether or not one of the sensors detects the passage of a person based on the signals from the sensors s1, s2,.... For example, when the sensor s1 detects the movement of a person, the vehicle ID “A1” associated with the sensor ID “s1” is acquired. When the sensor s3 detects the movement of a person, the vehicle ID “A2” associated with the sensor ID “s3” is acquired.

Next, the acquisition unit 121 determines whether the detected passage of a person is a boarding or alighting. Then, in the case of boarding, the number of passengers in the vehicle corresponding to the acquired vehicle ID is counted up.

For example, if the sensor s1 detects a passenger, the number of passengers P11 in the vehicle A1 at the station a1 is counted up. If the sensor s3 detects a passenger in the station a1, the number of passengers in the vehicle A2 at the station a1. P12 is counted up.

On the other hand, when the passing of the person is a get-off, the acquisition unit 121 counts up the number of people getting off from the vehicle corresponding to the acquired vehicle ID.

For example, when the sensor s1 detects the disembarking of a person, the dismount number Q11 of the vehicle A1 at the station a1 is counted up, and when the sensor s3 detects the disembarking of the person, the dismount number of the vehicle A2 at the station a1. Q12 is counted up.

The number of passengers P11, P12,... and the number of people getting off Q11, Q12,... Are stored in, for example, the storage unit 11, and the initial values of all of them are zero.

The above processing is continued while the train A is stopped at the station a1.

When the current time is 7:10, train A departs from station a2. At the same time, the train B arrives at the station a1.

When the train A departs from the station a2, the acquisition unit 121 departs from the station a2 based on the number of passengers and the number of disembarking passengers for each vehicle A1, A2,... At the station a2 (for example, P11 and Q11, P12 and Q12,... The passenger count related information F2 for each vehicle A1, A2,... At that time is calculated, for example, by the following procedure.

First, the acquisition unit 121 adds the passenger count P2j to the passenger count R1j of the vehicle Aj at the time of departure from the station a1 and subtracts the getting-off passenger count Q2j to obtain the passenger count R2j of the vehicle Aj at the departure from the station a2. Ask.

That is, for example, the number of passengers R21 of the vehicle A1 at the time of departure from the station a2 is obtained by adding the number of passengers P11 to the number of passengers R11 of the vehicle A1 at the time of departure from the station a1, and subtracting the number of passengers getting off Q11. Similarly, the number of passengers R22 of the vehicle A2 at the time of departure from the station a2 is obtained by adding the number of passengers P12 to the number of passengers R12 of the vehicle A2 at the time of departure from the station a1, and subtracting the number of passengers getting off Q12.

Therefore, for example, when R11=25 and P21=12 and Q21=6, R12=30 and P22=17 and Q22=9,..., The number of passengers R21=R11+P11−Q11=31, the number of passengers R22=R12+P22−Q22. =38, and so on.

Next, the acquisition unit 121 associates the ID “a2” of the station a2 with the number of passengers R21, R22,... Obtained as described above, so that the station a2 as shown in FIG. 10A, for example. The passenger number related information F2 for each vehicle A1, A2,... The configured passenger count related information F2 is accumulated in the storage unit 11 by, for example, the processing unit 12, and is used when configuring the next passenger count related information F3.

Next, the transmission unit 13 transmits the passenger count related information F2 acquired by the acquisition unit 121 as described above to the server device 2.

In the server device 2, when the server receiving unit 22 receives the passenger count related information F2, the server storage unit 231 stores the passenger count related information F2 in the server storage unit 21. Thus, in the server storage unit 21, for example, in the passenger count related information shown in FIG. 11, the portions corresponding to the vehicle IDs “A1”, “A2”,... And the station ID “a2”, that is, A1 and A pair of a2 and R21 (=31), a pair of A2 and a2 and R22 (=38),... Are stored.

When the train B arrives at the station a1, in the information processing device 1 mounted on the train B, the acquisition unit 121 detects the passenger count related information F1 regarding the passenger count of each vehicle B1, B2,... The process of acquiring by s1, s2,... Starts.

That is, the storage unit 11 stores, for example, operation schedule information about the train B, sensor/vehicle correspondence information, and the like. First, the acquisition unit 121 acquires the ID “a1” of the station a1 from the operation schedule information. ..

Next, the acquisition unit 121 determines whether or not one of the sensors detects the passage of a person based on the signals from the sensors s1, s2,.... For example, when the sensor s2 detects the movement of a person, the vehicle ID "B1" associated with the sensor ID "s2" is acquired. When the sensor s4 detects the movement of a person, the vehicle ID "B2" associated with the sensor ID "s4" is acquired.

Next, the acquisition unit 121 determines whether the detected passage of a person is a boarding or alighting. Then, in the case of boarding, the number of passengers in the vehicle corresponding to the acquired vehicle ID is counted up. For example, when the sensor s2 detects a passenger riding on a person, the number of passengers P11 on the vehicle B1 at the station a1 is counted up, and when the sensor s4 detects a passenger riding on a person, the number of passengers riding on the vehicle B2 at the station a1. P12 is counted up.

On the other hand, when the passing of the person is a get-off, the acquisition unit 121 counts up the number of people getting off from the vehicle corresponding to the acquired vehicle ID. For example, when the sensor s2 detects a person getting off the vehicle, the number of persons getting off Q11 from the vehicle B1 at the station a1 is counted up, and when the sensor s4 has detected a person getting off, the number of persons getting off from the vehicle B2 at the station a1. Q12 is counted up.

The number of passengers P11, P12,... and the number of people getting off Q11, Q12,... Are stored in, for example, the storage unit 11, and the initial values of all of them are zero. Further, when the station a1 is the starting station, there are usually no people getting off, so the number of people getting off Q11, Q12,...

The above processing is continued while the train B is stopped at the station a1.

When the current time is 7:11, train B departs from station a1. When the train B departs from the station a1, the acquisition unit 121 departs from the station a1 based on the number of passengers and the number of disembarking passengers for each of the vehicles B1, B2,... At the station a1 (for example, P11 and Q11, P12 and Q12,...) The passenger count related information F1 for each vehicle B1, B2,... At that time is calculated, for example, by the following procedure.

First, the acquisition unit 121 determines the number of passengers R1j of the vehicle Bj at the time of departure from the station a1 by subtracting the number of passengers Q1j from the number of passengers P1j. For example, the number of passengers R11 of the vehicle B1 at the time of departure from the station a1 can be obtained by subtracting the number of disembarking passengers Q11 from the number of passengers P11. Similarly, the number of passengers R12 of the vehicle B2 at the time of departure from the station a1 is obtained by subtracting the number of passengers getting off Q12 from the number of passengers P12.

Therefore, for example, when P11=18 and Q11=0, P12=13 and Q12=0,..., R11=P11−Q11=18, R12=P12−Q12=13,.

Next, the acquisition unit 121 associates the ID "a1" of the station a1 with the number of passengers Ri1, Ri2,... Obtained as described above, so that the station a1 as shown in FIG. 10B, for example. The passenger count related information F1 for each vehicle B1, B2,... The configured passenger count related information F1 is accumulated in the storage unit 11 by, for example, the processing unit 12, and is used when configuring the next passenger count related information F2.

Next, the transmission unit 13 transmits the passenger count related information F1 acquired by the acquisition unit 121 as described above to the server device 2.

In the server device 2, when the server receiving unit 22 receives the passenger count related information F1, the server storage unit 231 stores the passenger count related information F1 in the server storage unit 21. As a result, in the server storage unit 21, for example, in the passenger count related information shown in FIG. 11, portions corresponding to the vehicle IDs “B1”, “B2”,... And the station ID “a1”, that is, B1 and A pair of a1 and R11 (=18), a pair of B2 and a1 and R12 (=27),... Are stored.

Therefore, when the current time has passed 7:11, the server storage unit 21 stores the passenger count related information shown in FIG. At this time, it is assumed that the user arrives at the platform of the station a3 and performs an operation for inquiring about an empty vehicle.

In the terminal device 3, when the terminal accepting unit 32 accepts the inquiry, the terminal processing unit 34 first acquires the position information indicating the current position using a GPS receiver and the time information indicating the current position. get.

Next, the terminal acquisition unit 342 uses the station corresponding to the acquired position information as the departure station and the current time indicated by the time information as the departure time, the departure station, the departure time, and the arrival time received by the terminal reception unit 32. Do a timetable search based on the station.

Specifically, the terminal acquisition unit 342 acquires, from the server device 2, operation schedule information regarding a plurality of trains operating between the departure and arrival stations at or before the time indicated by the time information. Then, based on the acquired operation schedule information, train IDs of a plurality of trains to be selected, vehicle IDs of one or more vehicles constituting each train, arrival time of each train at the arrival station, and one train to another Search for train transfer stations and transfer times.

Next, the terminal acquisition unit 342 determines the vehicle ID (for example, the vehicle ID “A1”, “A2” of the next train A,..., The vehicle ID “B1 of the next train B” from the result of the timetable search as described above. ,"B2",...)). The terminal transmission unit 36 transmits an inquiry including the vehicle ID acquired by the terminal acquisition unit 342 to the server device 2.

In the server device, the server reception unit 22 receives the inquiry transmitted from the terminal device 3, and the server transmission unit 24 outputs the passenger count related information corresponding to the vehicle ID included in the inquiry via the server processing unit 23. It is acquired from the server storage unit 21 and transmitted to the terminal device 3.

In the terminal device 3, when the terminal receiving unit 33 receives the passenger number information corresponding to the vehicle ID, the terminal output unit 35 displays the vacant vehicle information regarding the vacant vehicle on the display or the basis based on the passenger number related information.
