Description

  The present invention relates to a track maintenance work support system capable of improving safety and improving work efficiency when requesting route setting during maintenance work on a railway.

  In the track maintenance work of the management section by the conventional centralized control system (CTC: Centralized Traffic Control), the field worker and the transport commander make a meeting, the transport commander operates the train centralized control device, Measures such as track closure and branching switch to prevent other trains from entering.

  However, since such measures depend on the attention of the transport commander, there is a risk of human error.

  For this reason, a maintenance work plan or the like is registered in the server in advance, and a route setting request is transmitted to the server using a terminal device (for example, a tablet terminal) that can be carried by a field worker when the maintenance work is performed. In addition, a track maintenance work support server, a system, and the like that improve safety by eliminating artificial traps by setting a direct route are disclosed (for example, see Patent Document 1).

[2. Explanation of operation]
A specific operation of the system 100 according to the embodiment of the present invention will be described in detail with reference to FIGS. Hereinafter, for the convenience of explanation, the processing mainly performed by the control unit of the terminal device 1 or the maintenance control server 2 will be described using “terminal device 1” and “maintenance control server 2” as the main subjects of the processing.

[2-1. Description of operation of terminal device 1]
Here, operation | movement of the terminal device 1 is demonstrated using the flowchart of FIG.
The terminal device 1 determines whether or not the field worker has performed this selection operation using the signal of the wiring schematic diagram displayed on the display unit (step S21).

  For example, as shown in FIG. 3, the display unit 13 of the terminal device 1 displays a wiring schematic diagram of a station premises or the like where maintenance work is performed, and in the vicinity of the on-site signal of “XX” in the wiring schematic diagram. Shows the signal levers 2LB, 2LC and 2LD of this in-field signal.

  When the terminal device 1 determines that this selection operation is not performed using a signal (step S21: No), the process returns to step S21, and when it is determined that this selection operation is performed using a signal (step S21: Yes), A route setting request by the selected signal lever is transmitted to the maintenance control server 2 (step S22).

  For example, the field worker selects a signal lever to which a route setting request is to be made from among a plurality of signal levers arranged in the wiring schematic displayed on the display unit 13 of the terminal device 1 as shown in FIG. Make a course setting request. More specifically, the signal lever is selected by clicking or tapping the signal lever 2LC, and a course from the main line “XX” to the third line is requested.

  Then, the terminal device 1 determines whether or not information on the branching device linked with the maintenance control server 2 has been received (step S23), and determines that information on the branching device or the like interlocking has not been received. (Step S23: No), it returns to Step S23, and when it is determined that the information of the linked branching device etc. has been received (Step S23: Yes), all the branches that are switched in conjunction with the course setting based on the received information Information such as a vessel is displayed so as to be identifiable (step S24).

For example, as shown in FIG. 4, the terminal device 1 uses all the branches that are switched in conjunction with the signal lever based on the information received as a result of requesting the route setting by selecting the signal lever 2LC by the field worker. In order to recognize the device etc., it is a rectangular identifier as shown in PT401, PT402, PT403, PT404, PT405, PT406, PT407, PT408, PT409 and PT410, and surrounds the branching device etc. on the display unit 13 of the terminal device 1. Display.
Further, the terminal device 1 displays the requested route RT41 (the route that travels from the main line of "XX direction" to the third line) with a thick line or a different display color so that it can be identified to the field worker.

  That is, the field worker selects all the branching devices to be switched in conjunction with the selected signal lever, specifically the branching devices PT401 to PT403 directly related to the requested route RT41, and the requested route. The information of the branching devices PT404 to PT410 that are not directly related (unintentionally) to RT41 and the requested route RT41 can be identified from the screen displayed on the display unit 13 of the terminal device 1.

  For this reason, it is possible to confirm not only the specific branching devices PT401 to PT403 to be converted but also other branching devices PT404 to PT410 that are switched in conjunction with each other. It can be grasped and safety can be improved when a course setting request is made during maintenance work.

  In addition, since all branching devices that are switched in conjunction with the selected signal lever, specifically, branching devices that are not directly related (unintended) to the requested route RT41 can be identified, unnecessary signals can be identified. This selection operation can be reduced and the work efficiency of the maintenance work can be improved.

  For example, at the maintenance work site having the interlocking relationship shown in FIG. 5, in order for a field worker to set a certain course, it is necessary to change four branching devices No. 21, 24, 25, and 26, etc. For this reason, it is assumed that it is necessary to select two signal levers, a signal lever 1LB of the in-field signal device and a signal lever 6L of the departure signal device.

  Then, when the field worker selects the signal lever 1LB of the on-site signal device on the screen of the terminal device 1, the display unit 13 of the terminal device 1 has 21, 21, 24, 25 based on the interlocking table shown in FIG. The information which 4 branching devices etc. of No. and No. 26 change in conjunction is displayed.

  In this case, the four turnouts No. 21, No. 24, No. 25, No. 26, etc., necessary for setting a certain course, can be converted at once by only selecting the signal lever 1LB of the on-site signal. I understand. For this reason, it can be recognized that it is not necessary to select the signal lever 6L of the departure signal substantially (the signal lever to which the three branching devices of No. 24, No. 25, No. 26, etc. are switched). The number of selection operations can be reduced, and the work efficiency of maintenance work can be improved.

  In this state, the terminal device 1 determines whether or not the field worker has operated the course change execution request displayed on the display unit 13 (step S25), and does not perform the change execution request operation. When it judges (step S25: No), it returns to step S21 and waits until it receives the selection as a signal for a course setting request again.

  For example, as shown in FIG. 4, when the field worker operates by clicking or tapping the “cancel” icon BT42 displayed on the display unit 13 of the terminal device 1, the process returns to step S21 and again sets the course. Wait until a request signal request is accepted. In addition, the mobile terminal 1 transmits “cancel route setting request” to the maintenance control server 2.

  On the other hand, when the terminal device 1 determines that the field worker has performed an operation of the course change execution request displayed on the display unit 13 (step S25: Yes), all of the terminal devices 1 that are switched in conjunction with the selected signal lever are used. The change execution request for the branching unit is transmitted to the maintenance control server 2 (step S26).

  For example, as shown in FIG. 4, when the site worker operates by clicking or tapping the “conversion execution request” icon BT41 displayed on the display unit 13 of the terminal device 1, the square identifier in FIG. A conversion execution request for converting all the branching devices and the like (PT401 to PT410) enclosed and enclosed is transmitted to the maintenance control server 2.

  That is, the field worker selects all the branching devices (PT401 to PT410) displayed on the display unit 13 of the terminal device 1 in accordance with the selected signal lever (PT401 to PT410) and the requested route RT41. If it is determined that there is no safety problem, a conversion execution request is transmitted to the maintenance control server 2 to determine the course, and if it is determined that there is a problem, a conversion execution request is made. Instead, by selecting the signal for the route setting request again, the safety can be improved when the route setting request is made during the maintenance work.

[2-2. Description of operation of maintenance control server 2]
Here, the operation of the maintenance control server 2 will be described with reference to the flowchart of FIG.

  The maintenance control server 2 determines whether or not the communication unit 25 has received a route setting request from the terminal device 1 (step S61). If the maintenance control server 2 determines that the route setting request has not been received from the terminal device 1 (step S61: No), the process returns to step S61.

  On the other hand, when the maintenance control server 2 determines that the route setting request has been received from the terminal device 1 (step S61: Yes), the maintenance control server 2 has received the route setting request, specifically selected. Based on the signal lever, reference is made to the interlocking chart information stored in advance in the database 26, and information such as all the branching devices that are switched in conjunction with the selected signal lever is extracted (step S62). Information on all the branching devices and the like that are switched in conjunction with the signal lever that has been transmitted is transmitted to the terminal device 1 (step S63).

  Then, the maintenance control server 2 determines whether or not the cancellation of the route setting request has been received from the terminal device 1 (step S64), and determines that the cancellation of the route setting request has been received from the terminal device 1 (step S64). S64: Yes), the process returns to step S61, and if it is determined that no cancellation of the route setting request has been received from the terminal device 1 (step S64: No), the process proceeds to step S65.

  Finally, the maintenance control server 2 determines whether or not a conversion execution request is received from the terminal device 1 (step S65), and determines that no conversion execution request is received from the terminal device 1 (step S65). : No), it returns to step S65, and when it is determined that a conversion execution request has been received from the terminal device 1 (step S65: Yes), conversion instructions for all branching devices and the like that are converted in conjunction with the selected signal lever Is transmitted to a train centralized control device (not shown) (step S66), and the train centralized control device (not shown) performs switching of a branching unit or the like.

  As described above, in the track maintenance work support system that directly sets the route using the terminal device carried by the field worker, the route setting request and the change execution request for selecting the signal lever on the display screen of the display unit are transmitted. In addition, a terminal device that displays the received information on the display unit, and a branching device that is switched in conjunction with the requested route based on the preset linkage chart information when a route setting request is received from the terminal device Information is transmitted to the terminal device to be displayed, and when a conversion execution request is received from the terminal device, a maintenance control server that transmits a switching instruction such as a branching device to the train centralized control device is set in advance. Based on the linkage chart information, information on all the branching devices that are switched in conjunction with the route setting is displayed on the display unit, so it is possible to grasp in advance the unintended switching of the branching devices, etc. Come, it is possible to improve safety during maintenance work during the course setting request.

  In addition, since information on all the branching devices that are switched in conjunction with the selected signal lever can be identified from the screen displayed on the display unit of the terminal device, all the branching devices that are switched in conjunction with each other In particular, because it is possible to identify branching devices that are not directly related (unintentionally) to the requested route, it is possible to perform the same branching device conversion as when many signal levers are selected with only a small number of signal levers. Therefore, the selection operation of unnecessary signals can be reduced, and the work efficiency of maintenance work can be improved.

(Modification 1)
[3-1. Clear indication of effective range of signal lever]
In the description of the embodiment, a signal lever to which a route setting request is to be made is selected from a plurality of signal levers arranged in a schematic wiring diagram displayed on the display unit 13 of the terminal device 1, and a route setting request is made. However, depending on the size of the display unit 13 of the terminal device 1, for example, when the wiring schematic is displayed on the terminal device 1 having a relatively small display screen such as a tablet terminal, the signal arranged in the wiring schematic The size of the lever (signal lever name) is also relatively small.

  When the size of the signal lever (signal lever name) placed in the wiring schematic is reduced, the position where the field worker taps (including clicks and touches) slightly shifts. In some cases, adjacent signal levers may be selected by mistake, and operability may become a problem.

  For example, even if the intention is to select the signal lever 2LC of the in-field signal device in FIG. 3, the adjacent signal lever 2LD may be erroneously selected.

  Of course, in such a case, the signal lever to be selected can be surely selected by enlarging and displaying the periphery of the signal lever. If you do not check the entire wiring diagram without displaying it in a reduced size, you will not be able to grasp information about all branching devices that are switched in conjunction with the selected signal lever, so you must repeat the screen scaling operation. Therefore, work efficiency will deteriorate.

  For this reason, while displaying the effective range (enclosed with a frame) of operation, such as a tap with respect to the signal lever displayed on the display part 13, on the terminal device 1, and when operating the effective range with a tap etc., as operation with respect to a signal lever It may be recognized.

  For example, the terminal device 1 operates the three signal levers 2LB, 2LC, and 2LD of the in-field traffic signal of “XX direction” in the wiring schematic diagram of FIG. 4 as shown in an enlarged view EX71 of the broken line portion of FIG. The effective ranges DM71, DM72, and DM73 are displayed surrounded by a frame, and when the effective range is operated with a tap or the like, it is recognized as an operation for the signal levers 2LB, 2LC, and 2LD.

  As shown in FIG. 7, the effective ranges DM71, DM72, and DM73 surrounded by the frame are wider than the size of the signal levers 2LB, 2LC, and 2LD. Can be improved.

  In other words, since the effective range of operations such as taps for specific signal levers can be known, it is possible to prevent other adjacent signal levers from being operated, to prevent erroneous operations due to tap mistakes, and to be safe when requesting route setting during maintenance work. Work efficiency can be improved.

(Modification 2)
[3-2. Priority of effective range of signal lever]
In the description of the modified example 1, as shown in FIG. 7, the effective ranges DM71, DM72, and DM73 of the operation may overlap each other due to the size of the display screen. For this reason, priority may be given to the effective range of operation, and an erroneous operation may be prevented.

  For example, as illustrated in FIG. 8A, when the operation effective ranges DM81, DM82, and DM83 overlap each other, the terminal device 1 displays the operation effective range DM82 on the display screen in the overlapped portion on the display screen. The effective ranges DM81 and DM83 are displayed on the back of the effective range DM82, thereby giving priority to the effective range DM82 over other effective ranges.

  That is, in FIG. 8A, the terminal device 1 recognizes an operation of the operation effective range DM82 when an overlapping portion between the operation effective range DM82 and the operation effective ranges DM81 and DM83 is operated.

  In FIG. 8A, the effective range of the operation may be filled so that the priority (front and back) can be easily distinguished instead of surrounding the effective range of the operation with a frame.

  Further, as shown in FIG. 8B, the effective operation ranges DM84, DM85, and DM86 may be enclosed by a figure such as an ellipse so as not to overlap each other.

  Further, as shown in FIG. 8C, the overlapping portions DC81 and DC82 of the operation effective ranges DM87, DM88, and DM89 may be excluded from the operation effective range as dead zones.

  In other words, prioritizing, ignoring, and avoiding duplication of the overlapping part of the effective range of operation can suppress erroneous operations due to tap mistakes, improving safety when requesting route setting during maintenance work and improving work efficiency. Can be improved.

In the description of the embodiment, the interlocking chart information is stored in the maintenance control server 2, but the interlocking chart information may be stored in the storage unit 14 on the terminal device 1 side.
That is, when the route setting request for selecting the signal lever on the display screen is operated, the terminal device 1 is switched in conjunction with the requested route based on the linked chart information stored in the storage unit 14 in advance. Information on the branching device or the like is displayed on the display unit, and when the route change execution request is operated, the change execution request is transmitted to the maintenance control server 2 together with the information on the branching device or the like. Then, the maintenance control server 2 transmits to the train centralized control device a switching instruction such as a branching switch that is switched in conjunction with the received information.

In this case, information on all the branching devices and the like that are switched in conjunction with the course setting based on the link chart information stored in the storage unit 14 on the terminal device 1 side is displayed on the display unit. Since a route setting request is not transmitted to the maintenance control server 2, the received route setting request is processed in the maintenance control server 2, and a branching device or a switch that is switched in accordance with the requested route. Thus, the load of the maintenance control server 2 can be reduced.
However, when the interlocking chart information is stored in the storage unit 14 on the terminal device 1 side, not all the interlocking chart information is stored from the relationship of the storage capacity of the storage unit 14 of the terminal device 1, but the maintenance work is performed. It is preferable to store only the linked chart information in advance.

In the description of the embodiment, the terminal device 1 displays information such as a branching device that is switched in accordance with the requested route based on the interlocking chart information on the display unit, but the maintenance control server 2 The display unit 23 may display information such as a branching device that is switched in conjunction with the requested route based on the interlocking chart information.
In this case, on the maintenance control server 2 side, since information on all the branching devices that are switched in conjunction with the route setting is displayed on the display unit 23, all the branching devices that are switched in conjunction with the route setting, etc. Can be grasped.

In the description of the embodiment and the like, the terminal device 1 displays information such as a branching device that is switched in accordance with the requested route based on the interlocking chart information on the display unit. On the maintenance control server 2 side, information indicating whether the switching of the branching device or the like that is switched in conjunction based on the interlocking chart information may be displayed on the display unit.
For example, an arrow is displayed in a direction in which the branching device or the like is switched as information indicating whether the switching of the branching device or the like is a localization or an inversion.

In addition, as information on whether the switch of the branching device is localized or inverted, not only the arrow is displayed in the direction of the switching of the branching device, but the arrow is color-coded according to the localization or inversion. May be. Alternatively, square identifier frames as shown in PT401, PT402, PT403, PT404, PT405, PT406, PT407, PT408, PT409, and PT410 in FIG. 4 may be displayed in different colors.
For example, when a branching device or the like is changed to a fixed position, it is displayed in blue. Of course, the inside of the square identifier in FIG. 4 may be filled with blue or yellow.

  In this case, information on the switching direction of all branching devices that are switched in conjunction with the route setting is displayed on the display unit, and information on the switching direction of all branching devices that are switched in conjunction with the route setting. Therefore, it is possible to grasp in advance information on the direction of change of an unintended branching device and the like, and it is possible to improve safety when a route setting request is made during maintenance work.

  In the description of the embodiment, on the terminal device 1 that can be carried by a field worker, information on all the branching devices and the like that are switched in conjunction with the route setting is displayed based on the preset interlocking chart information. The function to receive train schedule data, the function to display the schedule according to the train schedule data received, and to register the work plan, and to confirm the train schedule data and work plan confirmed two days before the work execution Then, information on all the branching devices and the like that are switched in conjunction with the route setting may be displayed on the maintenance area terminal having a function of finally checking whether or not the maintenance work is performed.

  In this case, at the stage of inputting the work details (work planning stage), information on the direction of change of all branching devices that are switched in conjunction with the course setting is displayed on the display unit, and is linked with the course setting. Therefore, it is possible to grasp the information on the direction of change of unintended turnouts, etc. in advance, and to ensure safety when setting a course during maintenance work. Can be improved.

  In the description of the embodiment and the like, the terminal device 1 (or the maintenance control server 2) displays on the display section information such as a branching device that is switched in accordance with the requested route based on the interlocking chart information. However, an audio output unit may be provided to notify information on all the branching devices that are switched in conjunction with the signal lever selected by the audio output.
