  Note that the area A10, the area A11, the EV button B4, and the ES button B5 are not displayed even when there is no transfer to the route displayed in the area A7. When there are a plurality of transfers on the route displayed in the area A7, a plurality of areas A10, A11, EV button B4, and ES button B5 are displayed.

The operator of the station terminal 30 inputs necessary assistance information to each input field of the input screen SC1. The processor 31 stores the input assistance information in the RAM 33 or the like.
Moreover, the operator of the station terminal 30 may input assistance information by inputting position terminal information. The location terminal information is input as follows, for example. The station terminal 30 acquires position terminal information from a IC (integrated circuit) provided in the position terminal 40 by short-range wireless communication or the like. Alternatively, for example, the station terminal 30 acquires the position terminal information from a barcode including the position terminal information displayed on the position terminal 40 using a scanner or a camera. The location terminal information includes the location terminal ID of the location terminal 40. The location terminal information may also include other assistance information. Other assistance information is input in advance by an operator of the location terminal 40, for example. For example, the operator of the location terminal 40 inputs various types of assistance information into the location terminal 40 in advance by inputting various types of assistance information including gender, equipment used, boarding station, alighting station, departure time or other assistance information. It saves the time and effort of speaking to station staff. Also, station staff can save time and effort to manually input various assistance information.
If the location terminal information is input when the processor 31 is in the standby state in steps S301 to S317, the processor 31 determines Yes in step S302 and proceeds to step S320.
In step S320, the processor 31 stores assistance information included in the location terminal information input in the standby state in steps S301 to S317 in the RAM 33 or the like. Then, the processor 31 controls the touch panel 36 to display the assistance information in each corresponding column of the input screen SC1. For example, the processor 31 displays the location terminal ID included in the assistance information in the area A13. The processor 31 returns to step S301 after step S320.

If the search button B1 is operated when the processor 31 is in the standby state of steps S301 to S317, the processor 31 determines Yes in step S303 and proceeds to step S305. However, when the search button B1 is operated in a state where the boarding station and the getting-off station are not input in the area A3 and the area A4, the processor 31 determines No in step S303 without determining Yes.
In step S321, the processor 31 causes the touch panel 36 to display several routes that meet the conditions as candidates based on the contents input to the areas A3 to A6. The route is a combination of trains that travel from the boarding station to the getting-off station. For example, the processor 31 acquires search candidates from the center server 10 or the station server 20. In this case, the center server 10 or the station server 20 searches for candidates based on the operation database. Alternatively, the processor 31 may search for candidates based on the operation database stored in the auxiliary storage device 34. Then, the processor 31 displays the candidate on the touch panel 36.
Note that when the area A6 is blank, the center server 10 or the station server 20 searches for a candidate, assuming that a predetermined time after the current time is input, for example. Alternatively, when the area A6 is blank, the center server 10 or the station server 20 searches for route candidates that indicate at which station the train is to be transferred without specifying the boarding time and the boarding train.

The operator of the station terminal 30 selects one from the candidates displayed on the touch panel 36.
In step S322, the processor 31 waits for selection of the candidate displayed in step S321. If the candidate displayed in step S321 is selected, the processor 31 determines Yes in step S322 and proceeds to step S323. At this time, the processor 31 stores information on the selected candidate in the RAM 33 or the like. The information is assistance information.

  In step S323, the processor 31 controls the touch panel 36 to update the display on the touch panel 36. That is, the processor 31 stops displaying the candidate displayed in step S321. Then, the processor 31 returns the display on the touch panel 36 to the input screen SC1 as shown in FIG. At this time, the processor 31 displays information on the candidate selected in step S322 in the area A7 of the input screen SC1. Furthermore, the processor 31 displays the area A10, the area A11, the EV button B4, and the ES button B5 as necessary. The processor 31 returns to step S301 after step S323.

If the EV button or the ES button is operated when the processor 31 is in the standby state in steps S301 to S317, the processor 31 determines Yes in step S304 and proceeds to step S324. However, the processor 31 does not determine Yes in step S303 when the EV button or the ES button is operated in a state in which information about the train that the person being assisted is scheduled to ride is not displayed in the area A7. It determines with No.
In step S324, the processor 31 acquires the position of the elevator when the operated button is an EV button. Then, the processor 31 acquires the position of the escalator when the operated button is the ES button. The processor 31 acquires information indicating the position of the elevator or escalator from the center server 10 or the station server 20, for example. Alternatively, the processor 31 acquires information indicating the position of the elevator or escalator from the station database stored in the auxiliary storage device 34.

  In step S325, the processor 31 displays the vehicle number and the door number in the area A8 and the area A9, or the area A10 and the area A11, based on the information acquired in step S324.

The operator of the station terminal 30-1 operates the transmission button B6 when the necessary assistance information has been input. Note that the operator does not need to fill in all the fields of the input screen SC1. The processor 31 transmits assistance information such as operating the send button B6 when the processor 31 is in the standby state of steps S301 to S317. If the operation has been performed, it is determined as Yes in step S305, and the process proceeds to step S319.
In step S326, the processor 31 generates an update request. The update request includes the assistance information input on the input screen SC1 and the assistance ID associated with the assistance information, that is, the assistance ID displayed in the area A2. The update request requests the center server 10 to update the assistance database by registering the assistance information in the assistance database. After generating the update request, the processor 31 instructs the communication interface 35 to transmit the update request to the center server 10. Upon receiving this instruction, the communication interface 35 transmits the update request to the center server 10. The transmitted update request is received by the communication interface 15 of the center server 10. The processor 31 returns to step S301 after step S326.

  On the other hand, in step S <b> 101 of FIG. 3, the processor 11 of the center server 10 waits for information to be received by the communication interface 15. If the information is received, the processor 11 determines Yes in step S101 and returns to step S101. Furthermore, the processor 11 newly generates a process or a thread. Then, the processor 11 starts processing starting from step S102 by the process or thread. That is, the processor 11 executes the process starting from step S102 in parallel or in parallel with the process of step S101.

  In step S102, the processor 11 determines whether or not the information received in step S101 is an update request. If the received information is an update request, the processor 11 determines Yes in step S102 and proceeds to step S103.

  In step S103, the processor 11 updates the assistance database by registering assistance information included in the received update request in the assistance database. That is, the processor 11 stores the assistance information included in the received update request in the assistance database in association with the assistance ID included in the update request. Note that when the assistance information associated with the same assistance ID as the assistance ID has already been stored in the assistance database, the processor 11 overwrites the already stored assistance information with the assistance information included in the update request, for example. To do.

  In step S104, the processor 11 transmits an assistance information notification to the station server 20 such as each necessary station. The assistance information notification includes assistance information and assistance ID included in the received update request. The assistance information notification notifies the user that assistance is required and information about the assistance. The necessary stations are, for example, the boarding station, the getting-off station, and the transfer station indicated by the assistance information. After generating the assistance information notification, the processor 11 instructs the communication interface 15 to transmit the assistance information notification to the station server 20 such as each necessary station. Upon receiving this instruction, the communication interface 15 transmits the assistance information notification to each station server 20. The transmitted assistance information notification is received by the communication interface 25 of each station server 20. After the process of step S104, the processor 11 ends the process or thread that is executing this process.

  On the other hand, in step S <b> 201 of FIG. 5, the processor 21 of the station server 20 waits for information to be received by the communication interface 25. If the information is received, the processor 21 determines Yes in step S201 and returns to step S201. Furthermore, the processor 21 newly generates a process or a thread. Then, the processor 21 starts processing starting from step S202 by the process or thread. That is, the processor 21 executes the process starting from step S202 in parallel or in parallel with the process of step S201.

  In step S202, the processor 21 determines whether or not the information received in step S201 is an assistance information notification. If the received information is the assistance information notification, the processor 21 determines Yes in step S202 and proceeds to step S203.

  In step S203, the processor 21 transmits the received assistance information notification to the necessary station terminal 30. Necessary station terminals 30 are, for example, the station terminals 30 used by the station staff in charge of assistance among the station terminals 30 whose installed stations indicated by the installed station information stored in the auxiliary storage device 24 are used. . The station server 20 stores the station terminal 30 in advance, for example. The processor 21 instructs the communication interface 25 to transmit the assistance information notification to each necessary station terminal 30. Upon receiving this instruction, the communication interface 25 transmits the assistance information notification to each station terminal 30. The transmitted assistance information notification is received by the communication interface 35 of each station terminal 30. After the process of step S203, the processor 11 ends the process or thread that is executing this process.

  On the other hand, if the assistance information notification is received when the processor 31 of the station terminal 30 is in the standby state of steps S301 to S317 in FIGS. 7 and 8, the processor 31 determines Yes in step S306 of FIG. Proceed to step S327.

  In step S327, the processor 31 generates an image corresponding to the assistance screen SC2 as shown in FIG. 11 based on the assistance information notification received in the standby state in steps S301 to S317. Then, the processor 31 instructs the touch panel 36 to display the generated image. In response to this instruction, the touch panel 36 displays an assistance screen SC2. However, if the assistance screen SC2 corresponding to the same assistance ID as the assistance ID included in the assistance information notification has already been displayed, the processor 31 displays the assistance screen SC2 instead of newly displaying it. The contents of the assistance screen SC2 being updated are updated based on the assistance information notification. The processor 31 returns to step S301 after step S327.

FIG. 11 is a diagram illustrating an example of an assistance screen SC2 displayed at the station ST2 that is a transfer station. The assistance screen SC2 is a screen for reporting assistance information. In FIG. 11, elements similar to those in FIG. 10 are denoted by the same reference numerals as in FIG.

In the area A21, it is displayed what number the cared person gets (rides) at the boarding station.
In the area A22, it is displayed how many doors of the vehicle displayed on the area A21 by the person being assisted (boarded) at the boarding station.
The area A23 is displayed on the station terminal 30 at the transfer station and the exit station. In the area A <b> 23, a scheduled time until a train that the attendant intends to get off reaches the use station indicated by the use station information stored in the auxiliary storage device 34 is displayed. For example, in the area A23 of the station terminal 30-2, the scheduled time until the train on which the person being assisted is arriving at the station ST2, which is a transfer station, is displayed. Further, for example, in the area A23 of the station terminal 30-3, the scheduled time until the train on which the person being assisted is arriving at the station ST3 which is the exit station is displayed. However, the scheduled time displayed in area A23 is the time when the train arrives at the time of the street.
The area A24 is displayed on the station terminal 30 at the transfer station and the exit station. In the area A24, the scheduled time until the train that the attendant is to get off arrives at the use station indicated by the use station information and the scheduled time when the train arrives at the use station are displayed. Note that, unlike the region A23, the scheduled time displayed in the region A24 is calculated based on the position information of the person being assisted. Similarly, the scheduled time displayed in the area A24 is calculated based on the position information of the person being assisted.
The area A25 is displayed on the station terminal 30 at the boarding station and transfer station. In the area A25, a scheduled time until a train scheduled for the person being assisted arrives at the use station indicated by the use station information is displayed. For example, in the area A23 of the station terminal 30-1, a scheduled time until the trained person to arrive at the station ST1 that is the boarding station is displayed. Further, for example, in the area A23 of the station terminal 30-2, a scheduled time until a trainee who is scheduled to transfer and rides arrives at the station ST2 as a transfer station is displayed.
In the area A26, the gender of the person being assisted is displayed.
In the area A27, the position terminal ID of the position terminal 40 possessed by the person being assisted is displayed.
In the area A28, an instrument used by the person being assisted is displayed.
In the area A29, necessary assistance contents are displayed.
In the area A30, transmission items input by other station staff are displayed. The area A30 is also a field for inputting items to be transmitted to other station staff.
In the assistance screen SC2, a part of the assistance information can be input. For example, assistance information can be input to the area A10, the area A11, the area A30, and the like.

  The completion button B7 is a button that is operated by the operator of the station terminal 30 when the assistance at the station where the station terminal 30 is used is completed among the assistances indicated by the assistance ID displayed in the area A2.

  The station staff operating the station terminal 30 can know the assistance information by looking at the assistance screen SC2 as described above.

Then, when the processor 31 is in the standby state of steps S301 to S317, if it is a predetermined time before the arrival time of the train on which the caregiver gets on and off, it is determined as Yes in step S307 and step S328 is performed. Proceed to The arrival time of the train on which the person being assisted gets on / off is the time at which the train on which the person assisted gets arrives at the station where the station terminal 30 is used and the train on which the person being assisted is on the station terminal 30. It is time to arrive at the station used. That is, the case where the predetermined time has elapsed from the arrival time of the train on which the caregiver gets on and off is the case where the time displayed in the area A23 or the area A24 is equal to or less than the predetermined time and the time displayed in the area A25. This is a case where becomes less than a predetermined time. Therefore, for example, at the station ST1 which is the boarding station, the processor 31 of the station terminal 30-1 determines that the trained person who is going to board the train arrives at the station ST1 at a predetermined time before step S307. It determines with Yes. Further, for example, at the station ST3 which is a disembarking station, the processor 31 of the station terminal 30-3, when a predetermined time before the time when the trained person to get off arrives at the station ST3, step S307. It determines with Yes. Then, in ST2 which is a transfer station, the processor 31 of the station terminal 30-2 receives a case where a predetermined time has elapsed from the time when the trainee who is scheduled to get off for the transfer arrives at the station ST2, and In step S307, “Yes” is determined twice, when a predetermined time has elapsed from the time at which the trainer who is going to board for the transfer arrives at the station ST2. Note that the processor 31 of the station terminal 30 of the transfer station determines Yes in step S307 when the predetermined time has elapsed from the time when the trainee who is scheduled to get off for the transfer arrives. If it is a predetermined time before the time at which the trainer who is going to board for the transfer arrives at the station ST2, Yes may not be determined in step S307.
The processor 31 performs the determination in step S307 using different criteria depending on whether it is determined that the diagram is disturbed or not. For this reason, the processor 31 needs to determine whether or not the diagram is disturbed. For example, the processor 31 determines whether the diagram is disturbed based on the information transmitted from the center server 10 or the station server 20 and indicating whether the diagram is disturbed. Alternatively, the processor 31 determines that the diagram is disturbed when the difference between the time displayed in the area A23 and the time displayed in the area A24 is equal to or greater than a predetermined time. Even when the person being assisted is on a different train from the schedule, the difference between the time displayed in the area A23 and the time displayed in the area A24 may be a predetermined time or more. Therefore, also in this case, the processor 31 determines that the diagram is disturbed.
If the processor 31 determines that the diagram is not disturbed, in step S307, the time displayed in the area A23 is equal to or shorter than the predetermined time and the time displayed in the area A25 is equal to or shorter than the predetermined time. If it is determined that the predetermined time has elapsed from the arrival time of the train on which the person being assisted gets on and off. On the other hand, when the processor 31 determines that the diagram is disturbed, in step S307, the time displayed in the area A24 is equal to or shorter than the predetermined time, and the time displayed in the area A25 is the predetermined time. In the following cases, it is determined that a predetermined time has passed from the arrival time of the train on which the person being assisted gets on and off. In addition, when the processor 31 determines that the diagram is disturbed, even when the time displayed in the area A25 is equal to or shorter than a predetermined time, the processor 31 is a predetermined time before the arrival time of the train on which the person gets on and off. It is not necessary to determine that it has become. This is because when the schedule is disturbed, there is a possibility that the train to be boarded does not come on Diamond Street, and even if the train arrives on Diamond Street, the person being assisted may not be able to get on the train.

In step S328, the processor 31 notifies that a predetermined time has elapsed from the arrival time of the train on which the person being assisted gets on and off. For this purpose, the processor 31 controls the speaker 37 to sound an alarm, for example. Moreover, the processor 31 may vibrate the vibrator with which the station terminal 30 is provided. Further, the processor 31 may change the display content of the touch panel 36. The display content includes, for example, a character string indicating that a train on which a caregiver gets on and off is approaching. The display content includes, for example, a list of items necessary for assistance. What is necessary for assistance is, for example, a board for getting on and off the train with a wheelchair. The processor 31 returns to step S301 after step S328.
The station staff who heard the alarm can know that a predetermined time has passed since the arrival time of the train on which the person being assisted gets on and off. And the station employee who heard the alarm confirms the assistance screen SC2, and starts assistance. And for example, the station staff of the station ST1 who confirmed the assistance screen SC2 displayed on the station terminal 30-1 assists the person being assisted based on the assistance information displayed on the assistance screen SC2. For example, the station staff at the station ST1 assists the target person to go up and down the stairs and board the stairs. Then, when the station staff at the station ST1 completes the assistance at the station ST1 for the non-assistant, the station staff performs an operation indicating completion of assistance, such as operating the completion button B7.
For example, the station staff of the station ST2 who confirmed the assistance screen SC2 displayed on the station terminal 30-2 assists the person being assisted based on the assistance information displayed on the assistance screen SC2. For example, the station staff at the station ST2 assists the target person to get on and off the train accompanying the transfer and to and from the stairs. Then, when the station staff at the station ST2 completes the assistance at the station ST2 for the non-assistant, the station staff performs an operation indicating completion of assistance, such as operating the completion button B7.
Further, for example, the station staff at the station ST3 confirming the assistance screen SC2 displayed on the station terminal 30-3 assists the person being assisted based on the assistance information displayed on the assistance screen SC2. For example, the station staff at the station ST3 assists the target person to get off and get on and off the stairs. Then, when the station staff at the station ST3 completes assistance at the station ST3 for the non-assistant, the station staff performs an operation indicating completion of assistance, such as operating the completion button B7.

If an operation indicating completion of assistance is performed when the processor 31 is in the standby state in steps S301 to S317, the processor 31 determines Yes in step S308 and proceeds to step S329.
In step S329, the processor 31 generates a first completion notification. The first completion notification includes the assistance ID displayed in the area A2, the station ID included in the used station information, and the getting-off station information. The getting-off station information is information indicating whether or not the station indicated by the station ID is a getting-off station. The first completion notification indicates that the assistance at the station indicated by the station ID has been completed for the assistance indicated by the assistance ID. After generating the first completion notification, the processor 31 instructs the communication interface 35 to transmit the first completion notification to the station server 20 installed at the station where the station terminal 30 is used. Upon receiving this instruction, the communication interface 35 transmits the first completion notification to the station server 20. The transmitted first completion notification is received by the communication interface 25 of the station server 20. The processor 31 returns to step S301 after step S329.

On the other hand, if the first completion notification is received, the processor 21 of the station server 20 determines Yes in step S201 of FIG. 5 and proceeds to step S202.
If the received information is not an assistance information notification, the processor 21 determines No in step S202 and proceeds to step S204.

According to the assistance system 1 of the embodiment, the station terminal 30 displays the expected time at which the train on which the person being assisted is arriving. The estimated time is derived by the center server 10 based on the position information of the position terminal 40 possessed by the person being assisted. Therefore, the station staff can know when the train on which the person being assisted arrives at the station by looking at the predicted time displayed on the station terminal 30 even when the schedule is disturbed. Accordingly, the station staff can easily determine when to start preparation for assistance for the person being assisted.
Moreover, the station terminal 30 displays the estimated arrival time of the train based on the position information of the position terminal 40 possessed by the person being assisted. For this reason, even if the station staff does not input the departure time of the train on which the person being assisted gets on the input screen SC1, the station staff at the transfer station and the getting-off station can know the estimated arrival time. In addition, even when the attendant takes time for assistance and the attendant gets on a different train from the schedule, the station staff at the transfer station and the departure station can know the estimated arrival time.
As described above, the assistance system 1 according to the embodiment is more accurate, quicker, and more convenient than information transmission using paper or the like.

  According to the assistance system 1 of the embodiment, the person being assisted can request help from a station staff or the like by operating the help button when a problem occurs. When the help button is operated, the station terminal 30 of the target station notifies that there is a person who is seeking help. The target station is based on the position of the position terminal 40 possessed by the person being assisted, and is, for example, the station where the train on which the person being assisted is present or the next station to be stopped. The station terminal 30 displays the time until the person being assisted arrives based on the position of the position terminal 40 possessed by the person being assisted. Therefore, the person being assisted can ask the station staff for unscheduled assistance, etc. even when the operation is abnormal, such as a timetable disruption. In addition, the station staff can easily know that unscheduled assistance is necessary by looking at the station terminal 30.

  According to the assistance system 1 of the embodiment, when the person being assisted is seeking help in the station, the station terminal 30 notifies that the person being assisted is in the station. Therefore, the station staff can easily know that help is also required for the caregiver in the station. The person being assisted can also ask for help when there are no station staff around.

The embodiment described above can be modified as follows.
In the above embodiment, the resumption of the interrupted assistance is based on an operation on the station terminal 30. That is, in the above embodiment, the center server 10 resumes assistance in step S128 in response to receiving the resume request. However, a mode in which assistance is automatically resumed when help is completed may be employed. That is, for example, the processor 11 of the center server 10 restarts the assistance specified by the assistance ID after the process of step S126, similarly to step S128. In this case, for example, the second completion notification includes an assistance ID for assistance to be resumed, that is, an assistance ID displayed in the area A50. Alternatively, the processor 11 may specify an assistance ID for assistance to be resumed from the help ID with reference to the assistance database.

  In the above embodiment, the assistance system 1 displays the assistance screen SC2 and the help screen SC3 on the station terminal 30 used by the station staff. However, the assistance system 1 may display the assistance screen SC2 and the help screen SC3 on the terminal used by the crew of the train. In this case, the crew can respond to help and the like.

When the positioning accuracy of GNSS is sufficiently high, the center server 10 may specify the boarding position of the person being assisted by acquiring the position information of the position terminal 40. In addition, the boarding position of the person being assisted includes the number of the vehicle on which the person being assisted is riding, the number of the door close to the person being assisted, and the like. In this case, the station staff does not need to input the area A8 to the area A11. For example, the processor 11 of the center server 10 specifies the boarding position of the person being assisted in step S111 based on the position information included in the received position notification. In step S113 or S124, the processor 11 generates the first time notification or the second time notification as including boarding position information indicating the boarding position of the person being assisted. On the other hand, when the first time notification is received, the processor 31 of the station terminal 30 adds the vehicle number and the door to the area A21 and the area A22 or the area A10 and the area A11 based on the boarding position information in step S330. Display the number. When the second time notification is received, the processor 31 of the station terminal 30 displays the vehicle number and the door number in the area A45 based on the boarding position information in step S335.
In this case, even when the person being assisted moves inside the vehicle after getting on, the station terminal 30 displays the boarding position after the person being assisted moves. Therefore, the station staff in charge of assistance at the transfer station or the getting-off station can wait at the position where the attendant gets off the train even if the attendant moves inside the car after boarding, by looking at the station terminal 30. it can.

The location terminal 40 may acquire location information using a method other than GNSS. For example, the location terminal 40 is a positioning system using an access point such as IMES (Indoor MEssaging System), Wi-fi or a mobile base station, a positioning system using a beacon using BLE (Bluetooth (registered trademark) low energy), etc. For example, a system that acquires position information based on radio waves transmitted from base stations other than artificial satellites is used. Alternatively, the location terminal 40 may use other positioning methods such as DR (dead reckoning). In addition, if an IMES transmitter, an access point such as Wi-fi, a mobile base station, a BLE beacon or other base station is installed indoors such as in a tunnel, the assistance system 1 can be used even when the train is indoors. Can be used. In addition, the assistance system 1 can be used in a subway or the like.
Further, the location terminal 40 may acquire its location information by using GNSS and other methods in combination. Thereby, the precision of position information can be raised. In addition, said base station is installed in each train, Based on the relative position from each said base station, the position terminal 40 exists in which vehicle of the said train, and the position terminal 40 of which door of the said vehicle You may specify whether it is nearby.

  For example, the location terminal 40 may include a plurality of help buttons corresponding to help contents. In this case, the location terminal 40 generates a help request including the help content. The help content may be, for example, wanting to go to the toilet, get off the train, get on the train or seek other help. The help information notification transmitted by the center server 10 includes the help content. The help content is also displayed on the help screen SC3.

  The location terminal 40 may be provided with a chat function or a call function for talking with a railway staff. For example, the location terminal 40 executes a chat function or a call function in response to the help button being operated. As a result, the person being assisted can tell the staff what kind of help is required. The attendant or the like instructs the transmission destination of the help information notification to the center server 10 as necessary based on the information obtained by the conversation with the person being assisted. In response to this, the center server 10 transmits a help information notification to the station server 20 of the station based on the instruction. Moreover, the said staff etc. instruct | indicate the center server 10 to include a help content in a help information notification as needed based on the information obtained by the conversation with a caregiver. Alternatively, the staff member or the like instructs the center server 10 not to transmit the help information notification when it is determined that the problem can be solved only by the conversation. In addition, the said staff gives said instruction | indication to the center server 10 by operating the terminal etc. which can communicate with the center server 10, for example. The terminal transmits information including the instruction content to the center server 10 based on the operation.

  The position terminal 40 may be capable of performing the same operation as when the help button is operated by voice recognition. In this case, it is easy to ask for help even for people who have difficulty in moving their fingers.

  The position terminal 40 may include an acceleration sensor. Then, the position terminal 40 may include information on acceleration or speed obtained by the acceleration sensor in the position notification. In this case, in step S111, the center server 10 may use the acceleration or speed in addition to the position information to determine the time at which the train on which the person being assisted arrives at each station.

You may install the GNSS receiver which receives a GNSS signal and measures a position in each train. Moreover, you may install a GNSS receiver in each station.
When a GNSS receiver is installed in a train, the position of the position terminal 40 in the vehicle can be measured with high accuracy by measuring the relative coordinates between the GNSS receiver and the position terminal 40. . Thereby, the center server 10 can specify in which vehicle in the train the position terminal 40 is located and which door is located nearby.
Further, when a GNSS receiver is installed at a station, by measuring the relative coordinates between the GNSS receiver and the position terminal 40, the position of the position terminal 40 in the station can be measured with high accuracy. Can do. Thereby, the center server 10 can specify which train the position terminal 40 is near, which vehicle is near, and which door is near.
The calculation of the relative position as described above is performed, for example, when the position terminal 40 receives information transmitted from the GNSS receiver. Then, the location terminal 40 transmits the measurement result to the center server 10. Alternatively, the center server 10 that has received the information transmitted from the location terminal 40 and the information transmitted from the GNSS receiver performs calculation based on the two pieces of information.

There may be a plurality of station servers 20 in one station.
One station server 20 may be shared by a plurality of stations. In this case, for example, the station server 20 shared by the stations ST1 and ST2 operates as the station server 20-1 and the station server 20-2.
The center server 10 may include some or all of the functions of the station server 20. In this case, the center server 10 may perform the same operation as the station server 20 instead of the station server 20. In this case, there may be a station where the station server 20 is not installed.
Further, the station server 20 may have some or all of the functions of the center server 10.
From the above, the center server 10 or the station server 20 is an example of a station service server. Alternatively, the center server 10 and the station server 20 cooperate to operate as a station service server.

The center server 10, the station server 20, or the station terminal 30 may perform part of the processing of the location terminal 40.
A part of the processing of the station terminal 30 may be performed by the center server 10 or the station server 20.
