Description

  The present invention relates to a train operation support system capable of partially releasing a track closure accompanying maintenance work in a railway and supporting a smooth operation of the train.

  Maintenance work such as correction of track misalignment (gauge, street, height, level, flatness, etc.), rail replacement, and ballast (gravel) replacement is performed using a maintenance vehicle. Such a maintenance vehicle performs work while traveling on a track on which a normal train or vehicle (hereinafter referred to as a train or the like) travels.

  However, some maintenance vehicles, unlike ordinary trains, run without short circuiting the track circuit (insulated running). In this case, the track circuit cannot detect the presence of the maintenance vehicle, There is a possibility of collision with trains.

  For this reason, an in-vehicle device having a GPS (Global Positioning System) function or an in-vehicle device having an ID (IDentifier) tag reading function is mounted on the maintenance vehicle, and the position (latitude and longitude) of the maintenance vehicle is detected by the GPS function. And a system that detects the position of a maintenance vehicle using position detection by reading an ID tag installed on the ground side and avoids a collision with a train or the like (for example, Patent Document 1). And 2).

JP 2007-237817 A JP 2008-247216 A

  However, in the existing line detection systems of Patent Documents 1 and 2, it is necessary to mount an in-vehicle device having a GPS function and an ID tag reading function on a maintenance vehicle, which results in an expensive system as a whole.

  In addition, when using a maintenance vehicle that performs insulated running in maintenance work without performing presence line detection as in Patent Documents 1 and 2, for safety, the entire range of movement of the maintenance vehicle (the maintenance vehicle is a garage) There is a need to close the tracks until leaving and returning.

  In this way, the track closure of the maintenance work range is usually performed at night when there is no train operation, so it does not interfere with normal train operation, but it operates at night such as freight trains and night trains. The train cannot proceed to the maintenance work range until the maintenance work is completed.

  However, depending on the line section, there may be a secondary line (retreat line) that temporarily retracts the maintenance vehicle during maintenance work, and the maintenance vehicle actually exists on such a secondary line. Even if this is the case, the location of the maintenance vehicle cannot be specified, so it is not possible to allow overtaking or passing of freight trains or night trains, and support smooth operation of freight trains or night trains. There was a problem that it was not possible.

  The subject of this invention is providing the train operation assistance system which can support the smooth operation of a train.

In order to achieve the above object, the present invention provides:
In the train operation support system that supports the smooth operation of trains,
A terminal carried by a maintenance vehicle operator who transmits a route setting request from a departure point to an arrival point where the maintenance vehicle travels, and transmits a route release request when the maintenance vehicle arrives at the arrival point. Equipment,
When the route setting request is received from the terminal device, the route of the requested route is closed and the route setting of the maintenance vehicle is registered, the route release request is received from the terminal device, and the registration is A maintenance control server that maintains track closure at the arrival point and releases other track closures in some cases;
Equipped with a,
The maintenance control server receives a route cancellation request from the terminal device when the starting point is a main line and the arrival point is a sub-main line, and if there is registration, the maintenance control server The track closure is maintained and other track closures are released .

  When the maintenance control server receives the route cancellation request from the terminal device and there is a registration that the track closure is a request from the maintenance vehicle, the maintenance vehicle may be at the arrival point. As you can see, maintaining the track closure at the arrival point and releasing the other track closures can partially release the track closures associated with the maintenance work, overtaking or passing other trains, Since it is possible to pass through a section where the track is originally closed, smooth operation of the train can be supported.

When the maintenance control server receives a route cancellation request from the terminal device when the arrival point is a retractable number line, and there is a registration that the track closure is a request from the maintenance vehicle, Since it can be seen that the maintenance vehicle is at the arrival point (secondary line such as a secondary main line), maintenance work can be performed by maintaining the closed line on the retreatable line and releasing the main line from being closed. It is possible to partially cancel the track closure that accompanies the train, so that other trains passing or passing each other can pass through the section where the track was originally closed, thus supporting the smooth operation of the train Can do.

Preferably, the maintenance control server receives a route cancellation request from the terminal device when a train approaches the section where the track is closed, and the arrival is received when there is a registration. The track closure at the point is maintained and the other track closures are released.
If the maintenance control server receives a route cancellation request from the terminal device when the train approaches the track closing section, and there is a registration that the track closing is a request from the maintenance vehicle, the maintenance vehicle Since it can be seen that there is a track at the arrival point, keep the track closed at the arrival point and release the other track closures, so that when the train approaches the track closed section, the track closure associated with the maintenance work will be closed. It can be partially released, and other trains passing or passing each other can pass through a section that is originally closed, so that smooth operation of the train can be supported.

Preferably, the maintenance control server maintains the track closure at the arrival point, releases other track closures, and the train is on the requested route. The track closing is not performed even when the route setting request is received from the terminal device.
The maintenance control server keeps track closed at the arrival point, and in the state where other track closures are released, it can be seen that the maintenance vehicle is on the secondary line (reservation line). If a train is present at the station, even if a route setting request is received from the terminal device 1, it is possible to avoid a collision with the train by passing the train as it is without closing the track.

  According to the present invention, a maintenance vehicle worker transmits a route setting request from a departure point to an arrival point where the maintenance vehicle travels, and transmits a route cancellation request when the maintenance vehicle arrives at the arrival point. The terminal device carried by the terminal device, and when the route setting request is received from the terminal device, the route of the requested route is closed and the route setting of the maintenance vehicle is registered, and the route cancellation request is received from the terminal device, And when there is the registration, it can be understood that the maintenance vehicle is located at the arrival point by providing the maintenance control server that maintains the track closure at the arrival point and releases other line closures. The track closure due to maintenance work can be partially released, and other trains passing or passing each other can pass through the section where the track was originally closed. Branch It can be.

[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 an operator of the maintenance vehicle has performed a route setting request operation (step S21). For example, an operator of the maintenance vehicle operates the terminal device 1 so as to designate a starting point and an arrival point of the route and transmit a route setting request to the maintenance control server 2.

  When the terminal device 1 determines that the maintenance vehicle operator has not operated the route setting request (step S21: No), the terminal device 1 returns to step S21, and the maintenance vehicle operator performs the route setting request operation. If it is determined that it has been performed (step S21: Yes), a route setting request is transmitted to the maintenance control server 2 via the communication network N (step S22).

  Then, the terminal device 1 determines whether or not the communication unit 15 has received a notification of completion of route setting from the maintenance control server 2 (step S23), and notifies the completion of route setting from the maintenance control server 2. If it is determined that it has not been received (step S23: No), the process returns to step S23, and if it is determined that a notification of completion of route setting has been received from the maintenance control server 2 (step S23: Yes), the display unit 13 A display to the effect that the course setting has been completed is performed (step S24).

  For example, the worker of the maintenance vehicle confirms that the setting of the course is completed on the display unit 13 of the terminal device 1, and then advances the maintenance vehicle from the starting point to set the course. Drive to the arrival point.

The terminal device 1 determines whether or not an operator of the maintenance vehicle has performed a route cancellation request operation (step S25). For example, if the maintenance vehicle travels on the route set and arrives at the arrival point, and the arrival point is a secondary main line (reservation line) that can be temporarily saved, In order not to hinder the train operation, the terminal device 1 is operated so as to promptly transmit a route cancellation request to the maintenance control server 2 to partially cancel the track closure, and then the arrival point. Perform maintenance work at
Of course, if the arrival point is not a secondary main line that can be temporarily saved (save line) or the like, maintenance work is performed with the track closed without performing a route cancellation request operation.

  When the terminal device 1 determines that the maintenance vehicle operator has not operated the route cancellation request (step S25: No), the terminal device 1 returns to step S25, and the maintenance vehicle operator performs the route cancellation request operation. When it is determined that it has been performed (step S25: Yes), a route cancellation request is transmitted to the maintenance control server 2 via the communication network N (step S26).

  Finally, the terminal device 1 determines whether or not the communication unit 15 has received a notification of completion of route cancellation from the maintenance control server 2 (step S27), and notification of completion of route cancellation from the maintenance control server 2 If it is determined that a notification of completion of route cancellation has been received from the maintenance control server 2 (step S27: Yes), the display unit 13 returns to step S27. A message to the effect that the cancellation of the course has been completed is displayed (step S28).

  For example, if the worker of the maintenance vehicle confirms that the display unit 13 of the terminal device 1 indicates that the course has been released, the maintenance vehicle cannot move the maintenance vehicle any further. Stay on the spot (arrival point).

[2-2. Description of operation of maintenance control server 2 when route setting request is received]
Here, the operation of the maintenance control server 2 will be described with reference to the flowchart of FIG. FIG. 3 is a flowchart showing an example of the operation when the maintenance control server 2 receives the route setting request.

  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 S31). If the maintenance control server 2 determines that the route setting request has not been received from the terminal device 1 (step S31: No), the process returns to step S31.

  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 S31: Yes), the maintenance control server 2 receives the route setting request from the maintenance vehicle. Whether or not (step S32).

  For example, whether or not the received route setting request is from a maintenance vehicle may be determined by checking transmission source information, information added to the route setting request, or the like. Other known techniques may also be used.

  When the maintenance control server 2 determines that the received route setting request is from the maintenance vehicle (step S32: Yes), it registers that the route setting is a request from the maintenance vehicle ( Step S33), the route is closed based on the received route setting request (Step S34).

  For example, to register that the route setting is a request from the maintenance vehicle, the maintenance control server 2 is provided with a flag indicating whether the route setting is a request from the maintenance vehicle, and the route setting is the maintenance. If it is a request from the vehicle, the flag is set (registered) to “1”.

  On the other hand, when the maintenance control server 2 determines that the received route setting request is not from the maintenance vehicle (step S32: No), the route is closed based on the received route setting request (step S34). ).

  In addition, when the route setting is not a request from the maintenance vehicle, the maintenance control server 2 sets a flag indicating whether the route setting is a request from the maintenance vehicle to “0” as necessary. It may be set (cancelled).

  Finally, the maintenance control server 2 transmits a notification that the setting (track closing) based on the route setting request is completed to the terminal device 1 (step S35).

  For example, as shown in FIG. 4A, when the maintenance vehicle MT41 is on the departure point SP41 and the maintenance vehicle operator performs a route setting request operation to the arrival point AP41, FIG. As shown in (b), the maintenance control server 2 registers that the route setting is for a maintenance vehicle, and then turns the branching device PT41 to the inverted position to set the route. Carry out track closing LL41 of the course.

  Then, for example, as shown in FIG. 4B, the worker of the maintenance vehicle MT41 confirms that the setting of the course has been displayed on the display unit 13 of the terminal device 1, Maintenance vehicle MT41 is caused to travel as shown by arrow MV41 from departure point SP41 to arrival point AP41.

[2-3. Description of the operation of the maintenance control server 2 when the route cancellation request is received]
Here, the operation of the maintenance control server 2 will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing an example of the operation when the maintenance control server 2 receives the course cancellation request.

  The maintenance control server 2 determines whether or not the communication unit 25 has received a route cancellation request from the terminal device 1 (step S51). If the maintenance control server 2 determines that the route cancellation request has not been received from the terminal device 1 (step S51: No), the process returns to step S51.

  On the other hand, when the maintenance control server 2 determines that the route cancellation request has been received from the terminal device 1 (step S51: Yes), the maintenance control server 2 indicates that the track closure related to the received route cancellation request is for maintenance. It is determined whether there is a registration indicating that the request is from the vehicle (step S52).

  For example, the maintenance control server 2 determines whether or not a flag indicating whether or not the route setting is a request from the maintenance vehicle is set (registered).

  When the maintenance control server 2 determines that there is a registration that the track closure related to the route cancellation request received from the terminal device 1 is a request from the maintenance vehicle (step S52: Yes), the maintenance vehicle Since it is known that the line is at the arrival point, the line closing at the arrival point is maintained, the other line closing is canceled (step S53), and the line closing related to the route cancellation request received from the terminal device 1 is maintained. When it is determined that there is no registration indicating that the request is from the service vehicle (step S52: No), all the track closures are released (step S54).

  Finally, the maintenance control server 2 transmits a notification that the cancellation of the setting (track closing) based on the route cancellation request is completed to the terminal device 1 (step S55).

  For example, as shown in FIG. 6, when the maintenance vehicle MT41 is in line with the arrival point AP61 and the maintenance vehicle operator performs a route cancellation request operation, the maintenance control is performed as shown in FIG. The server 2 confirms the registration that the track closure is a request from the maintenance vehicle, then switches the branching device PT61 to a fixed position and cancels the set route, and the track closure LL61 of the arrival point AP61. While releasing other track closures.

  Then, for example, as shown in FIG. 6, the maintenance control server 2 partially cancels the track closure, secures the course of the overtaking train TR61, and then passes the train TR61 as indicated by the arrow MV61. Let At this time, since the track closure LL61 of the arrival point AP61 is maintained, smooth operation of the train TR61 is supported and the safety of the maintenance vehicle MT41 is ensured.

  As described above, the maintenance vehicle operator who transmits the route setting request from the departure point to the arrival point where the maintenance vehicle travels, and transmits the route cancellation request when the maintenance vehicle arrives at the arrival point. When the route setting request is received from the terminal device 1 to be carried and the route setting request is received from the terminal device 1, the route of the requested route is closed, the route setting of the maintenance vehicle is registered, and the route release request is received from the terminal device 1 And if there is a registration, it can be seen that the maintenance vehicle is at the arrival point, so that the maintenance control server 2 that maintains the track closure at the arrival point and releases other track closures is provided. As a result, it is possible to partially cancel the track closure due to maintenance work, so that other trains passing or passing each other can pass through the section where the track is originally closed. Service It is possible to assistance.

  In the description of the embodiment, when the maintenance control server 2 receives the route cancellation request and confirms registration that the route setting is made by the maintenance vehicle, the maintenance vehicle is on the arrival point. Therefore, while closing the track at the arrival point and releasing other track closures, when the arrival point is a secondary main line (retractable number line), the terminal device 1 issues a route cancellation request. When receiving and confirming the registration that the course setting is due to the maintenance vehicle, keep the track closed at the arrival point (retractable number line such as the secondary main line) and cancel the other (main line) track closed Also good.

  In this case, the track closure associated with the maintenance work can be partially canceled, and other trains passing or passing each other can pass through the section that was originally closed. Smooth operation can be supported.

  In the description of the embodiment, when the maintenance control server 2 receives the route cancellation request and confirms registration that the route setting is made by the maintenance vehicle, the maintenance vehicle is on the arrival point. It is understood that the track closing at the arrival point is maintained and other track closings are released, but when a train approaches the track closing section, a route cancellation request is received from the terminal device 1 and the route setting is performed. When the registration is confirmed by the maintenance vehicle, the track closing at the arrival point may be maintained and the other track closing may be released.

  In this case, when the train approaches the track closing section, the track closing associated with the maintenance work can be partially canceled, and the other train that is overtaking or passing is originally closed. Since it can pass through a section, smooth operation of a train can be supported.

  Further, in the description of the embodiment, in order to support smooth operation of the train, the maintenance vehicle is temporarily retracted to the secondary line (retreat line), overtakes, or passes another train passing by. However, after passing the train, if necessary, the maintenance vehicle operator operates the route setting request again, confirms the completion of the route setting, and then advances the maintenance vehicle. Maintenance work can be continued.

  In such a course setting request again, the maintenance control server 2 keeps track closing at the arrival point and releases other track closures because the maintenance vehicle is at the arrival point. If the train is still on the requested route, the track may not be closed even if the route setting request is received from the terminal device 1.

  In this case, in the state where the track closure at the arrival point is maintained and the other track closures are released, it can be seen that the maintenance vehicle is located on the secondary main line (retreat line). Even if a track is still in place, even if a route setting request is received from the terminal device 1, it is possible to avoid a collision between the maintenance vehicle and the train by reliably passing the train without closing the track. can do.
