Shifts to the estimated arrival time calculation process. Here, once “inspection” is set, this setting is not changed until instruction information for instructing deletion of the dispatcher is input from the management terminal 30.

  In the dispatcher management table 256 shown in FIG. 9, the status type “other” indicates a status other than “moving” and “inspection” described above, and for example, position information could not be acquired. Shall be stored in the case.

Hereinafter, with reference to FIG. 27, the predicted arrival time calculation process in step S <b> 147 will be described.
FIG. 27 is a ladder chart showing the procedure of predicted arrival time calculation processing. In this process, steps S181 to S183 indicate a process executed in cooperation with the control unit 41 of the map data providing server 40 and a predetermined program stored in the storage unit 44.

  First, the estimated arrival time request information having the position information of the terminal identification information read in step S151 as the movement start position and the position information read in step S154 or S156 as the target position is provided as map data. It is transmitted to the server 40 (step S161).

  When the map data providing server 40 receives the predicted arrival time request information transmitted from the terminal management server 20 (step S181), the map data providing server 40 includes the position information of the movement start position and the target position included in the predicted arrival time request information. Based on the route search based on this, the time required for the movement from the movement start position to the target position is calculated (step S182). Then, this calculated time is transmitted to the terminal management server 20 as an estimated arrival time (step S183), and the processing of the map data providing server 40 is terminated.

  On the other hand, when the predicted arrival time transmitted from the map data providing server 40 is acquired (step S162), the terminal management server 20 uses the predicted arrival time as the transit point arrival predicted time and the failure point arrival predicted time, and the location information It associates with the terminal identification information set as the acquisition target and stores it in the estimated arrival time management table 257 (step S163).

  Next, the failure location management table 255 is referred to, and it is determined whether or not “failure location direct” is set as the route type of the failure location ID corresponding to the terminal identification information (step S164). Here, when it is determined that “failure position direct” is set as the route type (step S164; Yes), the process immediately proceeds to step S148 in FIG.

  In addition, when it is determined that “direct location of failure” is not set as the route type (step S164; No), information stored in the “name of destination” or “route distance” (facility identification information or Km) is read (step S165), and the kilometer corresponding to the read information is read based on the railway facility management table 252 and the like (step S166). Needless to say, when a specific kilometer is stored as the via kilometer, this value is read as it is.

  Subsequently, the nearest kilometer of the terminal identification information set as the location information acquisition target is read from the terminal location management table 254 (step S167), and the kilometer of this terminal identification information is read in step S166. The distance between the two positions is calculated from the difference from the distance corresponding to the via route, and this distance is the means of entry or travel from the via distance to the obstacle location (eg walking, tracked car, rail cart, etc.) The time required for the movement from the place of entry or the passing kilometer to the obstacle position is calculated (step S168). It should be noted that the speed of the moving means from the place of entry or the via route to the obstacle position is set in advance as setting information, but is not limited to this, and the speed of the moving means is instructed from the management terminal 30 It is good.

  Subsequently, the time calculated in step S168 is added to the estimated arrival time stored in the estimated transit point arrival time in the dispatcher management table 256 (step S169), and this added value is added to the dispatcher management table 256. (Step S170), the process proceeds to step S148 in FIG.

  Returning to FIG. 25, in step S148, it is determined whether all the terminal identification information stored in the dispatcher management table 256 has been read. If it is determined that all the terminal identification information has not been read (step S148). S148; No), the process returns to step S143 again, and the next terminal identification information is read from the dispatcher management table 256.

  On the other hand, when it is determined in step S148 that all terminal identification information has been read (step S148; Yes), this process ends. In addition, this process is always performed at the time of operation of the terminal management server 20, whereby the current position information is acquired from the mobile phone 10 possessed by the dispatcher every acquisition time T2.

In this way, it is possible to estimate the time required for the maintenance personnel to move from the current location to the maintenance target facility (failure location), so that it is possible to prepare a work plan and to operate the maintenance personnel quickly and efficiently. Can be done automatically.
In addition, even if there is a railway facility that should be routed to the maintenance target facility, it is possible to calculate the travel time from the current position of the maintenance staff to the relay position and the travel time from the relay position to the maintenance target facility, respectively. Since it is possible, the movement time from the current position of the maintenance staff to the maintenance target facility can be calculated more accurately.
Furthermore, since it is possible to check the status of the maintenance work based on the status type determined based on the distance between the positions indicated by the current location information of the mobile phone 10 and the location information of the maintenance target facility, maintenance personnel Can be operated quickly and efficiently.

  As described above, the management terminal 30 stores the fault location management table 255, the dispatcher management table 256, and the estimated arrival time management table 257 stored in the DB unit 25 of the terminal management server 20 under the control of the control unit 31. The acquired record can be acquired, and the acquired record can be displayed on the display unit 33.

  FIG. 28 is a diagram illustrating an example of information related to the state of the dispatcher displayed on the display unit 33. Here, similarly to the display area A7 in FIG. 24, records relating to the fault position and the via position are displayed in a list in the display area A11. When a specific fault position is specified from the displayed fault position, this designation is performed. A record relating to the dispatcher relating to the fault location is acquired from the dispatcher management table 256 and the terminal management table 253 of the terminal management server 20 and displayed in the display area A12.

  In addition, the state of the caller (terminal identification information) displayed in the display area A12 is acquired from the caller management table 256 and displayed in the display area A13. Furthermore, records corresponding to the route position and the obstacle position kilometer about the dispatcher, the via position arrival prediction time, the failure position arrival prediction time, etc. are acquired from the failure position management table 255 and the arrival prediction time management table 257, It is displayed in the display area A14. In the case of going straight to the fault location, the same values as the fault location are displayed for the “about kilometer” and the “predicted arrival time” of the destination.

  In FIG. 28, a state update button B9 is an operation button for instructing update of the “state” displayed in the display area A13. When the state update button B9 is pressed via the operation unit 32, the control unit 31 transmits to the terminal management server 20 state update request information for instructing update of the state of the caller (terminal detailed information) displayed in the display area A12. Hereinafter, an operation when the state update button B9 is pressed will be described with reference to FIG.

  FIG. 29 is a ladder chart showing the procedure of the process (state update process) related to the update of the dispatched person's state. In this process, steps S191 to S194 are processes executed in cooperation with the control unit 31 of the management terminal 30 and a predetermined program stored in the storage unit 34, and steps S201 to S207 are a terminal management server. 20 shows processing executed in cooperation with 20 control units 21 and a predetermined program stored in the storage unit 24. As a premise of this process, it is assumed that the screen shown in FIG.

  First, when the state update button B9 is pressed through the operation unit 32 and this operation signal is input (step S191), the state of the dispatcher (terminal identification information) displayed in the display area A12 of the display unit 33 is displayed. Status request information for requesting update is transmitted to the terminal management server 20 (step S192).

  In the terminal management server 20, when the status update request information transmitted from the management terminal 30 is received (step S201), the terminal identification information indicated by the status update request information is set as a position information acquisition target (step S202). ), The process proceeds to the terminal position acquisition process in step S203. In addition, since the terminal location information acquisition process of step S203 is the same process as step S14 (refer FIG. 14) mentioned above, description is abbreviate | omitted.

  Subsequently, based on the terminal identification information set as the position information acquisition target, a state determination process (step S204) and an estimated arrival time calculation process (step S205) are performed. Note that the state determination process and the predicted arrival time calculation process in steps S204 and S205 are the same as those in step S146 (see FIG. 26) and step S147 (see FIG. 27) described above, and thus description thereof is omitted.

  After step S205, a record corresponding to the terminal identification information indicated by the status update request information is read from the terminal location management table 254, the caller management table 256, and the estimated arrival time management table 257 (step S206). After being transmitted as update information to the management terminal 30 (step S207), the processing of the terminal management server 20 ends.

  On the other hand, when the status update information transmitted from the terminal management server 20 is received in the management terminal 30 (step S193), various information of the terminal detailed information displayed on the display unit 33 is updated according to the status update information. At the same time, the position and display of the icon image superimposed on the map data are updated (step S194), and this process ends.

  Thus, since the position information and status of the (terminal identification information) related to the caller can be updated in accordance with the instruction from the user, the status of the contestant can be monitored in real time.

  As described above, various types of information related to the mobile phone 10 and the railway facility existing at the position related to the maintenance target area instructed from the management terminal 30 are read from the DB unit 25 of the terminal management server 20 and the display unit of the management terminal 30 Since it is possible to specify maintenance personnel suitable for the maintenance target facility, the maintenance personnel can be operated quickly and efficiently.

  The detailed configuration and detailed operation of the railway maintenance support system 100 in the above embodiment can be changed as appropriate without departing from the spirit of the present invention.

  For example, in the above embodiment, each table stored in the DB unit 25 of the terminal management server 20 can be referred to by all the management terminals 30. However, the present invention is not limited to this, and the failure location management table 255, dispatcher management For the record associated with the registered branch office name as in the table 256, access control may be performed so that only a request from the management terminal 30 belonging to the corresponding branch office name can be referred to. In this case, it is preferable to control so that all tables stored in the DB unit 25 can be referred to in response to a request from the management terminal 30a provided in the operation headquarters.

  Moreover, in the said embodiment, although the map data provision server 40 was set as the structure provided with the map data DB part 45, not only this but the terminal management server 20 is good also as an aspect provided with the map data DB part 45.

  In the above-described embodiment, the mobile phone 10 is used as the mobile communication terminal. However, the mobile phone 10 is not limited to this and may be a PDA (Personal Digital Assistant) having a GPS function, a notebook computer, or the like. Moreover, the terminal management server 20 is good also as an aspect which acquires present position information from a portable communication terminal using networks, such as the internet.

  In the above embodiment, a specific railway facility is designated as the maintenance target facility (failure location). ) May be designated as the inspection target section. In this case, it is possible to specify the inspection target section by setting the starting point side of the inspection target section as a via position (passing kilometer distance) and the end point side as a desired kilometer distance. For example, a route in the event of an earthquake, etc. It is possible to provide support for inspection work in the tunnel.

  When the maintenance target facility is designated as the inspection target section, the work state of the dispatcher is based on the records stored in each table stored in the DB unit 25 of the terminal management server 20 in the form shown in FIG. It may be displayed. In this figure, the kilometer related to a specific route that is subject to maintenance is displayed as a reference axis, and the terminal detailed information and work related to the worker in the section are located at the position corresponding to the kilometer that is the section to be inspected. Various information indicating the state is displayed (see display areas A15 to A18 in the figure).

  Below the display areas A15 to A18, a chart representing the work state is displayed corresponding to each worker (see the charts C1 to C4 in the figure). The work state is determined based on the current position information of the mobile phone 10 possessed by the dispatcher and the position information of the obstacle position (via position), as in the above embodiment, and the position (about kilometer) that has already passed. The display formats are different as “inspected” and “not inspected”, respectively, for the unpassed positions. In addition, as a section where no inspection is performed, an “inspection unnecessary” section is represented in a display format different from the above “inspected” and “not inspected” (see chart C5). In addition, when inspecting a predetermined section, it moves in a specific direction (upward direction or downward direction) along the route. Therefore, the direction corresponding to this movement direction is displayed as arrows in the display areas A15 to A18. It is displayed in conjunction with the working state.

  As described above, the display mode as shown in FIG. 30 makes it possible to intuitively grasp the state of maintenance work in a predetermined section on the route. The display mode is not limited to this.

  In the above-described embodiment, the terminal management server 20 calculates the predicted arrival time. However, the present invention is not limited to this, and may be calculated by each management terminal 30. In this case, there is a possibility that the amount of traffic exchanged between each management terminal 30 and the map data providing server 40 will increase, and the predicted arrival times for the same worker may be calculated redundantly. Therefore, a mode in which the terminal management server 20 performs control as in the above-described embodiment is preferable.

  In the above embodiment, the predicted arrival time from the current position of the worker to the failure position is provided only to the management terminal 30. However, the present invention is not limited to this. For example, it is transmitted to the cellular phone 10 of the worker. It is good also as an aspect.
