DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a construction / maintenance work, a breakage of a rail, and the like between stops where a normal double track automatic block system (hereinafter referred to as a normal operation system) is being implemented.
Temporary single-track operation using one of the available double-track tracks (hereinafter referred to as double-track single-track operation) when the normal operation method between stops is impossible due to a track failure due to roadbed outflow, etc. The present invention relates to a train operation control system for performing a shift to a train while ensuring the driving direction and safety of a train and, when a route is opened, a signal indicating that fact.

[0002]

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

[0003] Therefore, in the conventional interlocking device, when performing maintenance work or the like between stops, the train must be suspended in order to secure a working time zone. However, suspending a train leads to a decline in service and is not an easily adopted method.

[0004] Therefore, in order to avoid the suspension of the train, the work time is divided and maintenance work is performed between trains, or maintenance work is performed during nighttime when train operation intervals are sparse. Have gone.

When a train is driven in a direction opposite to a normal driving direction from an adjacent stop to pull a vehicle stopped due to a failure between the stops to a nearest depot, etc. In this case, a traffic signal for entering / leaving the reverse-operated track and a block signal for reverse-track operation between stops are required. However, at present, such facilities are not installed, and in order to make the train enter and enter the reverse-operated track, it is necessary to manually confirm the opening of the section, that is, to talk with the adjacent station manager to stop the train etc. by telephone communication. After confirming whether there is no train between adjacent stops or whether there is a train other than the faulty vehicle by walking between the stops, the route is opened, that is, the turning machine is turned by the handwheel ( (Hereinafter referred to as hand-turning)
In addition to locking the points, a method of presenting a signal instructing the crew to proceed by a flag signal or a hand signal substitute (hereinafter, referred to as a substitute hand signal) is used.

Further, in the case where one of the tracks is unusable due to the collapse of the track or the outflow of the roadbed in the middle of the stop in the double track section, the train in which the track in the predetermined driving direction can be used between the adjacent stop and the normal train is used. It is possible to drive by the method and the course described in the interlocking table can be used,
Trains that cannot use the track in the prescribed driving direction will not operate according to the normal operation method, and the traffic signals listed in the interlocking table will also be unusable.
In addition, the section opening confirmation by hand and ensuring the safety of the train between the stops by hand (hereinafter referred to as the guidance ceremony) are performed.

However, of the above-mentioned prior arts, the method of performing maintenance work between trains by dividing the work time zone has a high risk of tentacle accident during work, The method of performing the maintenance work during the time period is a so-called 3K work, and has a drawback that it is very difficult to secure work personnel.

[0008] In addition, eliminating labor shortage, eliminating dangerous work,
In order to enable efficient maintenance work and safe train operation, it is possible to introduce a large maintenance machine and mechanize the maintenance work.However, it is necessary to extend the maintenance work time. Yes, as the number of trains increases, it is difficult to secure long working hours.

[0009] In the case of towing a vehicle that has stopped due to a failure between stops, to a nearby depot or the like, the above-described conventional method involves confirming section opening, switching a switch, and locking. In addition, it requires human resources to train the trains, and it is very difficult to secure train safety between stops.

Also, in the case of a collapse of a track or an outflow of a roadbed in the middle of a stop in a double track section, a conventional operation method using a line without a traffic signal or a driving direction setting circuit is used. Skilled personnel are required to perform single-line operation without performing such operations, and manual handling in the event of equipment failure requires a short period of time and requires regular training and sufficient experience.

FIG. 4 is a schematic diagram of the premises wiring during the normal operation, but the premises wiring diagram during the double-track single-line operation is as shown in FIG.
FIG. 7 shows an interlocking table based on the premises wiring diagram of FIG. 6 (herein, referred to as a double-track single-line switching control chart in order to distinguish it from the interlocking table during normal operation). 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. 10 shows an example of a double-track single-track existing track management table.

Next, the operation when switching from the normal operation to the double-track single-track operation will be described with reference to the flowcharts in FIGS. First, in step 100, when the computer terminal designates normal double-track operation to double-track single-track operation (double-track single-track switching "X11
L)), in step 101, reference is made to the row of double-track single-track switching lever (X11N) in the control chart for double-track single track switching. Then, in step 102, the signal information (5R, 6R, 7L,
8L unlocked) and (X5R, X6R, X7L, X8L, X
9R, X10R, X17L, X18L locks), refer to the signal lever reservation table, and use the inside and departure traffic lights during normal operation (5R, 6R, 7L, 8L), and the inside and departure during substitute single-track operation. Course (X5R, X6R, X7
L, X8L, X9R, X10R, X17L, X18L)
Is checked to determine whether or not the route has been set, and route conflicts during switching are prevented. If the on-site / departure signal has already been set, the transition to double-track single-track operation is disabled in step 103. .

If the validity is OK in step 103, in step 104, is there a train on the track circuit (5RT) of the line designated as the operating line during double-track single-track operation (hereinafter referred to as the designated line)? In addition, a check is made as to whether or not the set route remains (hereinafter, referred to as a conflict check). If another train is present on the designated track, the transition to the double-track single-track operation is disabled in step 103.
Then, after the transition to the double-track single-track operation is disabled in step 103, the process ends.

Next, if the contention check is performed in step 104 and the result is OK, then in step 105, the track state of the track circuit ([D3T, D2T, D1T]) in the designated track, the adjacent stop (△ station) Double track single track switch lever (= X12
A request is made to the adjacent stop to determine whether or not the handling conditions in L) match (hereinafter referred to as a match check).

[0032] The interlocking device at the adjacent stop stops at step 106.
In the above, referring to the control diagram for double-track single-track switching based on the check request information received from the interlocking device at the stop, handling status of the operating track (D3T, D2T, D1T) and double-track single-track switching lever (X12L) To check. Then, in step 107, if there is a train on the train, a response of "setting NG" is switched to a double track single track, and if the handling state does not match (X12N), a response of "setting pending" is returned. If the leverage states match, a response of "setting OK" is returned to the station.

In step 108, the interlocking device of the station disables the transition to the double-track single-track operation when another train is on the designated track according to the response result from the adjacent stop, and switches the double-track single track to the adjacent stop. If the handling status does not match, switch the transportation command or double-track single-track of the station manager, and suspend the transition process until the handling status matches by this handling. If the setting is OK, the mode information is stored in the double-track single-track mode management table. (X11L) is registered.

Further, in step 109, the "unlock" of (5R, 6R, 7L, 8L unlock) of the traffic signal information shown in the lock column of the double-track single-track switching lever (X11N) in the double-track single-track switching control chart is performed. By registering the handling disabled information in the signal lever reservation table of the traffic signal in place of "lock", the handling of the on-site / departure traffic signal during double-track single-track operation is prohibited. Also, the traffic signal information (X5R, X5R, X5R, X5) shown in the lock column of the double-track single-track switching lever (X11L) in the switching control chart.
6R, X17L, X18L unlocked), the handling during double-track single-track operation is permitted by registering handleable information in the signal lever reservation table of the substitute route.

The operation after shifting to the double-track single-track operation by the double-track single-track switching lever is as shown in FIGS. In step 110, when a double-track single-track lever (X12R) corresponding to the designated track is designated by a computer terminal or the like,
First, in step 111, the substitute route and the reservation state in the double-track single-track direction are checked by referring to the driving direction lock information in the double-track single-track lever reservation table, and in step 112, the double-track single-track switching control chart is performed. Of the specified line (5RT) is checked with reference to the lock column information of the above.

Next, at step 113, based on the lock column information of the control diagram for switching to a single track, the state of the specified track (D3T, D2T, D1T) on the interlocking device at the adjacent stop, and the driving direction of the single track (△). The setting status of the station (X12R) is requested by adding the check information (X12R).

In step 114, the interlocking device at the adjacent stop, which has received the check request for the double-track single-track driving direction from the interlocking device at the stop, determines whether the operating line is on-track based on the on-rail status information in the on-rail management table, and the double-track single-track mode management table. The double-track single-track switching is used to check the setting state, and the double-track single-track driving direction is checked according to the driving direction control information in the direction lever reservation table, and that there is no train between adjacent stops and the double-track single-track driving direction When it is confirmed that is handled by the receiving side (X12R inversion), in step 115, a response permitting the setting of the double-track single-track driving direction is returned to the interlocking device at the stop.

When the interlocking device of the adjacent stop returns a permission response, the interlocking device of the station changes the driving direction of the double-track single-track by registering the driving direction control information in the double-track single-track lever reservation table in step 116. (X12
R), and in step 117, a request is made to the interlocking device at the adjacent stop to check the double-track single-track driving direction. Opening display is performed on the computer terminal.

In addition, the interlocking device at the adjacent stop registers the driving direction check information in the double-track single-track lever reservation table in step 119 based on the double-track single-track driving direction check request, thereby setting the double-track single-track driving direction of the driving track. Then, in step 120, a response indicating that the checking has been completed 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 / landing point (lower or lower) are designated from a computer terminal or the like will be described with reference to FIG. For example, when the setting of the substitute route (X5R) is requested in step 130, the multi-track single-track interlocking table is searched in step 131, and the substitute route is described in the multi-track single-track switching control chart or the signal leverage reservation is performed. The validity check is performed to see whether the information that can be handled is registered in the table, and whether the double-track single-track lever (X12R) is handled on the exit side of the △ station by referring to the lock column information of the link table. Prevent erroneous input of course setting.

Next, in step 132, the change control of the relevant switch (21) and the confirmation of the control result (opening direction) of the relevant switch (hereinafter referred to as "path check") are performed.
As a result of the route check, when the control of the point machine is normally completed, a route reservation of a substitute route is made in step 133 based on the route division lock column information and the landing point information in the interlocking table. According to the specification of the lock column information in the table, the driving direction setting information (alternate route number) is registered in the double-track single-line lever reservation table, so that only the driving direction cannot be released. In step 135, the computer terminal and the substitute route are substituted. A progress announcement is made.

When there is a request for re-establishment of the substitute route by entering the train or input from the computer terminal, the stop route is controlled on the substitute route, and there is no response to the effect that the route has become the stop condition. When 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 erased, the route reservation and the driving direction reservation are canceled, and the display on the computer terminal is displayed before the route request. To the state of.

Also, the train (A) has a substitute departure route (X5
R), when entering the destination track circuit (5RT), the direction lock management information (track information of the entered train (track circuit name)) is registered in the track management table to perform double track single track operation. The direction lock is performed, and the on-rail information is transferred to the interlocking device of the adjacent stop, so that the adjacent stop is locked in the double-track single-track driving direction.

Similarly, the track circuit information (D3
T, D2T, D1T), the train is tracked in the middle of the stop, and when the train is no longer in the middle of the stop, that is, when the vehicle enters the stop yard via the substitute parking route (X1R) of the adjacent stop, the double track of the adjacent stop is performed. The direction lock management information in the single-line direction lever reservation table is deleted, the double-track single-track operation direction is unlocked, and a request for unlocking the double-track single-track operation direction is made to the interlocking device at the stop.

Further, when there is a request for unlocking the double-track single-track operation direction from the interlocking device at the adjacent stop, the direction lock management information in the double-track single-track lever reservation table at the stop is erased to unlock the double-track single-track drive direction. I do.

Next, the operation when the double-track single-track operation is designated to the double-track operation will be described with reference to FIG. First, when the transition to the double-track operation is designated in step 140, in step 141, the substitute departure route (X5
R, X6R, X9R, X10R)
L, X8L, X17L, X18L) are not set, and in step 142, the track circuits (5RT, U1T, U2T, U3T,
[D3T, D2T, D1T, 4LT]) Checking the presence of a track and switching to a double track single track, and a double track single track switch (= X12N) at the adjacent stop (△ station) specified in this lock column is at the same position (N side). Check the handling status to see if it is handled. If the check is OK, the mode information in the double-track single-track mode management table is deleted. However, if a substitute route has already been set, or if another train is present on the designated track, the operation proceeds to double-track operation in step 143. Transfer is not allowed. However, if there is a faulty train in the middle of the station, to be able to drive a rescue train,
An emergency switching function is provided, and when this function is handled, the operation is forcibly switched to double-track single-track operation or double-track operation.

Next, in step 144, based on the (5R, 6R, 7L, 8L unlocked) information among the signal information shown in the lock column of the double-track single-track switching lever (X11N) in the switching control chart, By registering the handleable information in the signal leverage reservation table of 取 扱 い, the handling of the on-site / departure signal at normal times is permitted, and step 145 is performed.
, Substitute routes (X5R, X6R, X7L, X8
Based on the L, X9R, X10R, X17L, and X18L chain lock) information, the non-handleable information is registered in the leverage reservation table of the substitute route, thereby prohibiting the handling of the substitute route in the normal operation mode.
