Furthermore, when data such as a map of a station is stored in the nonvolatile memory 38, the CPU 35 may correct the estimation result of the current position of the mobile terminal using the map data.

  The state estimation process is a process for estimating the state of the station staff possessing the mobile terminal 3. The CPU 35 estimates whether or not a predetermined task is appropriately executed as the station staff state. For example, the CPU 35 estimates the state of the station staff based on the detection history acquired from the mobile terminal 3 and the current position of the station staff possessing the mobile terminal 3 estimated by the position estimation process.

  Specifically, the CPU 35 acquires station staff work information, which is information indicating a work schedule of station staff for each station, from the operation management server 2 or other devices. The CPU 35 recognizes the work of the day determined for each station staff by referring to the station staff work information. There are various types of business such as “train entry confirmation”, “home safety confirmation”, “ticket gate service”, and “information”. Each business has a predetermined position on the station or on the platform. Each business has a predetermined action pattern. Specifically, in the task of “train entry confirmation”, it is stipulated that an action such as pointing confirmation is performed at a predetermined position on the platform.

  The CPU 35 determines whether or not the current position of the station staff possessing the mobile terminal 3 estimated by the position estimation process is a position corresponding to the determined work. In addition, the CPU 35 determines whether or not the detection history acquired from the mobile terminal 3 is a pattern corresponding to a predetermined job. Specifically, the CPU 35 determines whether or not the current position of the station staff possessing the portable terminal 3 estimated by the position estimation process is a predetermined position on the platform corresponding to the “train entry confirmation” task. In addition, it is determined whether or not the detection history acquired from the mobile terminal 3 has a pattern corresponding to the pointing indication confirmation of the “train entry confirmation”.

  When the CPU 35 determines that the current position of the station staff possessing the mobile terminal 3 estimated by the position estimation process is not a position corresponding to the determined work, or the detection history acquired from the mobile terminal 3 is determined. If it is determined that the pattern does not correspond to the given job, it is determined that the predetermined job is not properly executed. In other words, the CPU 35 determines that the current position of the station staff possessing the mobile terminal 3 estimated by the position estimation process is a position corresponding to the determined work, and the detection history acquired from the mobile terminal 3 is If it is determined that the pattern corresponds to the predetermined job, it is determined that the predetermined job is being executed appropriately.

  The notification information generation process is a process of generating notification information to be notified to a station staff possessing the mobile terminal 3. The notification information is information notified to the station staff, and includes, for example, some corresponding instruction or communication items. The notification information is, for example, information indicating an instruction to follow a staff member who is not performing work and a position to follow.

  When the CPU 35 determines that the predetermined job is not properly executed in the above state estimation process, the CPU 35 instructs the other station staff's portable terminal 3 to enter the follow-up of the job not being executed, In addition, notification information indicating the position of the follow destination is generated.

  The information providing process is a process of transmitting notification information to the mobile terminal 3. The CPU 35 transmits the notification information based on the position indicated by the notification information generated by the notification information generation process (that is, the position where the follow service is performed), the result of the position estimation process, and the result of the state estimation process. To decide. The CPU 35 transmits notification information to the determined mobile terminal 3.

  For example, the CPU 35 determines whether or not it is possible to follow the work of other station staff for each station staff who possesses the mobile terminal 3 (whether or not to follow). For example, the CPU 35 determines whether or not the station staff possessing the mobile terminal 3 can follow in accordance with the importance set in advance for each job. For example, the CPU 35 determines that a station employee who performs a task whose importance is less than a predetermined value can be followed. In addition, the CPU 35 may determine whether or not follow-up is possible depending on whether or not there is a station staff who is performing similar operations nearby. In addition, the CPU 35 may cause the station staff to follow another business by causing another station staff to follow the work performed by a certain station staff. For example, the CPU 35 may convert the importance level lower when there are a plurality of station employees performing the same business nearby, or may change the importance level according to the time zone.

  CPU35 transmits alerting | reporting information with respect to the portable terminal 3 of the station employee who is close to the position of a follow destination and the possibility of a follow is possible. In addition, the CPU 35 does not transmit the notification information to the mobile terminal 3 possessed by the station staff who is closest to the follow destination position and can be followed or not, but notifies the plurality of mobile terminals 3 in the order of close to the follow destination position. It may be configured to transmit information.

  The information providing device 4 is associated in advance with the mobile terminal 3 operated at the station where the information providing device 4 is installed. The information providing apparatus 4 sequentially executes the position estimation process and the state estimation process based on the information from the associated mobile terminal 3. Thereby, CPU35 grasps | ascertains sequentially the present position and state of a station employee who possesses the portable terminal 3. FIG. Further, when there is information to be notified to the station staff, the CPU 35 executes the notification information generation process and the information provision process. Thereby, CPU35 produces | generates alerting | reporting information, determines the transmission destination of the produced | generated alerting | reporting information, and transmits alerting | reporting information to the determined portable terminal 3. FIG.

  The information providing device 4 may be provided for each of a plurality of stations, and may be configured to be associated in advance with the mobile terminal 3 operated at the plurality of stations.

  FIG. 4 is an explanatory diagram for explaining a state on the platform 41 of the station where the train stops. FIG. 5 shows an example of a table indicating the position and state of each station employee in the example shown in FIG. The information providing apparatus 4 stores the table of FIG. 5 in, for example, the nonvolatile memory 38 or the RAM 37.

On the platform, there are station staff having a mobile terminal 3A (terminal ID: XXXA), station staff having a mobile terminal 3B (terminal ID: XXXB), and station staff having a mobile terminal 3C (terminal ID: XXXC). Further, it is assumed that there is a station employee having a mobile terminal (terminal ID: XXXD to XXXF) not shown in the station. The CPU 35 of the information providing device 4 performs a position estimation process and a state estimation process, thereby performing a process scheduled process for each mobile terminal, a process result indicating whether the process scheduled process is being appropriately executed, a current position, Then, it is determined whether or not follow is possible, and the table of FIG. 5 is sequentially updated.

  For example, if the CPU 35 determines that the job scheduled for processing is being executed appropriately, the CPU 35 sets the processing result to “OK”. On the other hand, when the CPU 35 determines that the job to be processed is not properly executed, the CPU 35 sets the processing result from “OK” to “NG”.

  Further, the CPU 35 sequentially updates the current position according to the result of the position estimation process. The current position is, for example, information indicating the floor such as “1F” and “2F”, information indicating the position on a certain first axis on the horizontal plane, and the first position in the direction perpendicular to the first axis on the horizontal plane. Information indicating the position on two axes is combined.

  In addition, the CPU 35 sequentially updates whether or not to follow according to the result of the state estimation process.

  The CPU 35 refers to the table of FIG. 5 and determines whether or not the processing result “NG” has occurred. When the processing result of “NG” occurs, the CPU 35 generates notification information for requesting other station staff to follow, and transmits the notification information to the portable terminal 3 possessed by a nearby station staff who can follow.

  Next, the operation of the information providing apparatus 4 when specifically requesting other station staff to follow the work will be described with reference to the examples of FIGS.

  The CPU 35 acquires operation information from the operation management server 2. The operation information is information indicating a train operation state on the railway. For example, the operation information indicates that it is a predetermined time before the train arrives. When the operation information indicating that the train arrives is obtained, the CPU 35 refers to the table in FIG. 5 and determines whether or not the station staff possessing each station service terminal 3 is executing a predetermined task. Further, the CPU 35 acquires timetable information indicating a predetermined train arrival and departure time, recognizes the time when the train arrives based on the timetable information, and refers to the table in FIG. 5 before a predetermined time before the train arrives. Further, a configuration may be adopted in which it is determined whether or not the station staff possessing each station service terminal 3 is executing a predetermined job.

  As a result of determining whether or not the station staff possessing each station service terminal 3 is performing a predetermined task, the CPU 35 is assigned to the station staff having the portable terminal 3B to which “safety confirmation on the home” is assigned as the task scheduled to be processed. Suppose that it is determined that a predetermined job is not being executed. In this case, the CPU 35 generates notification information that instructs the station staff having the mobile terminal 3 </ b> B to perform the business and to assist (follow) the business of “safety confirmation on the home”.

  Furthermore, the CPU 35 specifies the mobile terminal 3 that is close to the position where the station staff having the mobile terminal 3B is scheduled to perform business and is capable of following. According to the example of FIGS. 4 and 5, the CPU 35 specifies the mobile terminal 3 </ b> C. The CPU 35 transmits notification information to the specified mobile terminal 3C. Thereby, CPU35 makes the station employee who has 3 C of portable terminals follow the station staff who has the portable terminal 3B.

Further, the information providing apparatus 4 determines whether or not the station staff possessing each mobile terminal 3 is performing a predetermined job based on information transmitted from the plurality of mobile terminals 3. If it is determined that the predetermined job is not being executed, the information providing device 4 instructs the mobile terminal 3 of the station staff located near the location to give an instruction to follow the job and the position to follow. Send information. Thereby, the information provision apparatus 4 can provide the information for making it correspond instead to the nearby station staff when the predetermined | prescribed operation | work is not performed.

  Further, the information providing apparatus 4 estimates the congestion situation in the station premises or on the platform from the movement of the station staff, and transmits notification information to the mobile terminal 3 instructing to collect the station staff at the crowded location according to the congestion situation. It may be a configuration.

  For example, the CPU 35 of the information providing device 4 estimates the congestion situation near the station staff who owns the mobile terminal 3 based on the detection result of the walking sensor 17 acquired from the mobile terminal 3. For example, based on the detection result, the CPU 35 detects a specific operation such as the frequency of movement of the station staff carrying the mobile terminal 3, the speed of movement, the distance of movement, or running. CPU35 calculates the score which shows a congestion degree for every portable terminal 3 based on specific operation | movement, such as the frequency of movement of the station employee who carries the portable terminal 3, the speed of movement, the distance of movement, and running. CPU35 transmits the alerting | reporting information which instruct | indicates to gather in the vicinity of the portable terminal 3 whose score exceeded the predetermined threshold value with respect to the portable terminal 3 whose score does not exceed the predetermined threshold value. Thereby, CPU35 can distribute a station employee according to a congestion condition.

  Further, for example, the CPU 35 of the information providing device 4 may estimate whether or not an impact has been applied to the station staff possessing the mobile terminal 3 based on the detection result of the walking sensor 17 acquired from the mobile terminal 3. For example, when an acceleration of a predetermined value or more is detected in the detection result of the walking sensor 17, the CPU 35 determines that some abnormality has occurred, such as a station employee carrying the mobile terminal 3 receiving violence or falling. When the CPU 35 determines that such an abnormality has occurred, the CPU 35 transmits notification information instructing to go to the location where the abnormality has occurred to the mobile terminal 3 near the location where the abnormality has occurred. Thereby, CPU35 can make a nearby station employee perform confirmation of abnormality.

  In addition, the CPU 35 may be configured to generate a trajectory of movement of the station staff possessing the mobile terminal 3 based on the detection result of the walking sensor 17 acquired from the mobile terminal 3. By generating such a trajectory, it can be determined whether the station staff is moving along a predetermined route.
