Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to construction / maintenance work, rail breakage / breakage between railroad stops where a normal double-track automatic block system (hereinafter referred to as a normal operation system) is implemented.
Temporary single-track operation using one of the double-track tracks that can be used when the normal operation method between stops is not possible due to a track failure due to roadbed leakage (hereinafter referred to as double-track single track operation) The present invention relates to a train operation control system that shifts to a train while ensuring the driving direction and safety of a train, and when a route is opened, a signal to that effect is displayed.

[0002]

2. Description of the Related Art In a conventional interlocking device, a train is operated between stops by a normal operation method that is determined in advance for each stop, and when a train enters or leaves a stop, a predetermined operation is performed. The course can be set only in the direction, and it is impossible to freely change the driving direction.

Therefore, in the conventional interlocking device, when performing maintenance work between the stops, the train must be suspended in order to secure a working time zone. However, stopping the train is not a method that can be easily adopted because it leads to a decline in service.

[0004] Therefore, in order to prevent the train from being suspended, maintenance work is performed by dividing the work time period between train arrivals, or at night hours when train operation intervals are sparse. I'm gone.

When a train is driven in a direction opposite to the normal driving direction from an adjacent stop to pull a vehicle stopped due to a failure between the stops to the nearest depot, etc. For line operation), a traffic signal for entering and advancing to the reverse line and a block signal for reverse line operation between stops are required. However, at present, such equipment is not installed, and in order to advance or enter a train on a reverse-tracked line, it is necessary to manually confirm the opening of the section, that is, by telephone contact, to make a meeting with the adjacent station manager such as a train stop. After confirming whether there is a train between adjacent stops or a train other than a broken car by actually walking between the stops, opening the route, that is, changing the rolling machine with a handwheel ( Hereinafter referred to as hand-turning conversion)
In addition to the locking of the rolling machine, a flag signal or a hand signal substitute is used to show a signal for instructing the crew to proceed (hereinafter referred to as a substitute hand signal).

Further, in the case where one of the tracks cannot be used in the middle of the stop in the double-track section due to the collapse of the track or the outflow of the roadbed, the train in which the track in the predetermined driving direction can be used between the adjacent stops is normally operated. It is possible to drive according to the method, and the course shown in the interlocking table can be used,
Trains that can not use the track in the specified driving direction will not be able to operate using the normal operation method, and the traffic lights listed in the interlocking table will also be unusable, so handle the rolling machine by hand,
Also, we are checking the opening of sections manually and ensuring the safety of trains between stops (hereinafter referred to as the instruction ceremony).

[0007]

However, among the above-mentioned conventional techniques, the method of performing maintenance work by dividing the work time zone and when the train arrives has a large risk of a touch accident during the work, and also at night. The method of performing maintenance work in a time zone is a so-called 3K work, and there is a drawback in that it is very difficult to secure a worker.

In addition, elimination of labor shortage, elimination of dangerous work,
It is also possible to introduce a large maintenance machine to mechanize the maintenance work in order to enable efficient maintenance work and safe train operation, but it is necessary to extend the maintenance work time for that. Yes, it is difficult to secure long working hours as the number of trains increases.

Further, in the case of pulling a vehicle stopped due to a failure between the stops to the nearest depot, etc., in the above-mentioned conventional method, section opening confirmation, switching of the turning machine, and locking are performed. It requires a skilled person to operate the train on the reverse line and it is very difficult to secure the safety of the train between the stops.

Further, in the case where the track is depressed in the middle of the stop or the roadbed flows out in the middle of the double track section, the operation using the track without the traffic signal in the normal operation system or the operation direction setting circuit is used as in the conventional case. Skilled workers are required to operate the single track without doing so, and it requires manual labor and daily training and sufficient experience in order to handle equipment abnormally in a short time.

An object of the present invention is to provide a train operation control system capable of safely performing double-track single-track operation without requiring skill.

In the train operation control system in which the interlocking device provided with the route locking means for registering the reservation of the above in the track section reservation table, is installed at each stop,
The driving direction between stops and the route to enter and exit the track used during reverse line driving are specified in advance in the interlocking diagram file, and a signal transmission line connecting interlocking devices at adjacent stops to each other and a single line operation should be performed. When the route is specified, the train operation direction is set after exchanging information for ensuring the safety of the train between the interlocking devices at the adjacent stops via the signal transmission route, and the route of the train is set. A double-track single-track operation control means for performing control based on the interlocking information defined in the interlocking diagram file and for displaying the route opening by registering the track section of the related route in the track section reservation table. It is a feature.

Further, the present invention is a track circuit unit set by dividing a track into a plurality of sections in order to detect the presence of a train such as a train when a pair of rails of the track is short-circuited by a train or the like. A track section reservation table in which track reservation information including reservation information for track setting and on-rail information of the section is registered, and a plurality of tracks to be subject to interlocking control are defined by the traffic signal type and the start / end point information.

Similar to 2, the table is a table for registering the reservation as a turning machine according to the setting of a route or work. In addition, the route configuration table 16 stores the conversion position data of the turning machine indicating the state of the route that is currently opened.

FIG. 4 was a schematic diagram of the internal wiring during normal operation, but the internal wiring diagram during double-track single-line operation is as shown in FIG.
An interlocking table based on the internal wiring diagram of FIG. 6 (herein referred to as a double-track / single-line switching control table in order to distinguish it from the interlocking table during normal operation) is as shown in FIG. 8 shows an example of a double-track single-track mode management table, FIG. 9 shows an example of a double-track single-track direction lever reservation table, and FIG.

Next, the operation when switching from the normal operation to the double-track single-track operation will be described with reference to the flowcharts of FIGS. 11 to 13. First, when the normal double-track operation is designated by the computer terminal to the double-track single-track operation in step 100 (double-track single-track switching lever "X11
In the case of handling "L"), in step 101, the line of the double-track single-track switching lever (X11N) of the double-track single-track switching control chart is referred to. Then, in step 102, the signal information (5R, 6R, 7L, which is designated in this lock column by switching the double-track single-track,
8L unlocking) and (X5R, X6R, X7L, X8L, X
9R, X10R, X17L, X18L locks), referring to the signal lever reservation table, the inside / departure traffic lights (5R, 6R, 7L, 8L) during normal operation, and the substitute / inside departures during double-track single-track operation Path (X5R, X6R, X7
L, X8L, X9R, X10R, X17L, X18L)
Validity check is performed to determine whether or not has been set, to prevent route conflict during switching, and to disallow transition to double-track single-track operation in step 103 when the on-site / departure signal has already been set. .

If the validity is OK in step 103, is there a train in the track circuit (5RT) of the track designated as the operation track for double-track single-track operation (hereinafter, designated track) in step 104? In addition, a check is made to see if there are any set routes remaining (hereinafter referred to as a conflict check), and if another train is on the designated track, the transition to the double-track single-track operation is made impossible in step 103.
Then, in step 103, after the transition to the double-track / single-track operation is disabled, the processing ends.

Next, in step 104, if the conflict check is OK and the result is OK, in step 105, the track circuit ([D3T, D2T, D1T]) of the track circuit in the designated track is in the on-line state, and the adjacent stop (Δ station) Double track Single track switch (= X12
It is requested to the adjacent stop whether or not the handling states of L) match (hereinafter, referred to as matching check).

The interlocking device of the adjacent stop is step 106.
In the above, referring to the check request information received from the interlocking device at the stop concerned, referring to the control chart for double-track single-track switching, the on-track check of the driving track (D3T, D2T, D1T) and the handling status of the double-track single-track switching lever (X12L) To check. Then, in step 107, if there is a train in the train, a response of "setting NG" is switched, and if the handling state does not match (X12N), the response of "setting is suspended" is switched. When the handling states of the levers match, the response of "OK" is returned to the station.

In step 108, the interlocking device of the station makes it impossible to switch to the double-track single-track operation when another train is on the designated track based on the response result from the adjacent stop, and switches the double-track single-track at the adjacent stop. If the handling status of the lever does not match, the transportation command or the station manager's double-track single-track switching is performed, and the transition processing is suspended until the handling status matches with this handling. If "Setting OK", the mode information is stored in the double-track single-track mode management table. Register (X11L).

Further, in step 109, the "unlock" of the signal information (5R, 6R, 7L, 8L unlocking) of the signal information shown in the lock column of the double-track single-track switching lever (X11N) of the double-track single-track switching control chart. By registering the unhandled information in the signal lever reservation table of the traffic signal instead of "lock", it is prohibited to handle the on-site / departure traffic signal during double-track single-track operation. In addition, the traffic light information (X5R, X) shown in the lock column of the double-track single-rail switching lever (X11L) in the switching control chart.
6R, X17L, X18L unlocking), the handling permission information is registered in the signal lever reservation table of the substitute route to permit handling during double-track single-track operation.

The operation after shifting to the double-track single-track operation by the double-track single-track switching lever is as shown in FIGS. 14 to 17. When the double track single track direction lever (X12R) corresponding to the designated track is designated from the computer terminal or the like in step 110,
First, in step 111, the substitute route and the reservation state of the double track single track direction lever check table are checked with reference to the driving direction locking information of the double track single track direction leverage table, and in step 112, the double track single track switching control chart. With reference to the lock column information, the status of the designated track (5RT) is checked.

Next, at step 113, the status of the designated track (D3T, D2T, D1T) being present in the interlocking device at the adjacent stop, and the double track single track operating direction (Δ), based on the lock column information of the double-track single track switching control chart. The setting information of the station (X12R) is requested by adding the check information (X12R).

In step 114, the interlocking device of the adjacent stop, which has received the check request for the driving direction of the double track single track from the interlocking device of the relevant stop, checks the existing line of the driving track based on the existing line status information of the existing line management table and the double track single line mode management table. Check the setting status of the double-track single-track by switching the two-track single-track, and check the setting status of the double-track single-track driving direction based on the driving direction control information in the direction lever reservation table. When it is confirmed that is handled by the receiving side (X12R upside down), in step 115, a response permitting the setting of the double-track single-track driving direction is returned to the interlock device at the stop.

When a permission response is returned from the interlocking device at the adjacent stop, the interlocking device at the station in question outputs the double-track single-track driving direction by registering the driving direction control information in the double-track single-track direction lever reservation table in step 116. (X12
(R inversion), and in step 117, the interlocking device of the adjacent stop is requested to check the double-track single-track driving direction, and when a response of completion of the checking is received from the interlocking device of the adjacent stop, in step 118, The opening indication is displayed on the computer terminal.

Further, the interlocking device at the adjacent stop sets the double-track single-track driving direction of the driving track by registering the driving-direction check information in the double-track single-track direction lever reservation table in step 119 based on the double-track single-track driving direction check request. Further, in step 120, the response of completion of the checking is returned and the opening of the driving direction is displayed on the computer terminal.

Next, the operation when the signal type (substitute route) and the starting point / ending point (bottom book, bottom Δ direction) are designated from the computer terminal will be described with reference to FIG. For example, when the substitute route (X5R) is requested to be set in step 130, the double track / single track interlocking table is searched in step 131, and the substitute track is described in the double track / single track switching control chart, or the signal lever reservation is made. Check the validity of whether the handleable information is registered in the table and whether the relevant double track single track lever (X12R) is handled on the exit side of the station by referring to the lock column information in the interlocking table. Prevent erroneous input of route setting.

Next, at step 132, the conversion control of the relational turning machine (21) and the control result (opening direction) of the relevant turning machine (hereinafter referred to as route checking) are performed.
As a result of the route check, when the control of the turning machine is normally completed, the route reservation of the substitute route is made based on the route division lock column information and the point information in the interlocking table in step 133, and further linked in step 134. By designating the lock column information in the table, the driving direction setting information (substitution route number) is registered in the double-track single-line direction lever reservation table to disable only the driving direction, and in step 135, the computer terminal and the substitution route are set. To show progress.

When there is a request to relocate a substitute route due to a train entry or an input from a computer terminal, the substitute route is controlled to show a stop, and there is a response indicating that the route has been shown to be a stop. At this time, the route reservation information in the track circuit reservation table and the driving direction lock information in the double-track single-track direction lever reservation table are deleted to reserve the route and cancel the reservation for the driving direction, and the display on the computer terminal is displayed before the route request. Return to the state of.

Further, the train (A) is a substitute departure route (X5
