Description

The present invention relates to a train control device for operation management, a railway vehicle equipped with the device, and a train control method.

Regarding train control related to operation management, for example, Patent Document 1 discloses the following techniques. "An operation management system including a plurality of ground elements provided in a predetermined section and an on-board device mounted on a plurality of vehicles and communicating with the ground element when passing through the ground element. The approach distance between the plurality of vehicles is calculated based on the distance information between the ground elements, the relative distance information between the ground element and the vehicle, and the train length of the vehicle, and the approach distance between the own train and the own train is calculated. When the nearest train is in the same direction, the distance information between the ground elements and the relative distance information between the ground element and the nearest train ahead is added, and the relative distance information between the ground element and the own train is added. And the train length of the front nearest train is subtracted to calculate the approach distance between the own train and the front nearest train, and the calculated approach distance is allowed in advance between the own train and the front nearest train. When the distance between the train and the train is less than or equal to the allowable inter-vehicle distance, different types of alarms are notified between the own train and the nearest train ahead. "
As a result, the approach of the vehicle is detected more accurately to provide a highly safe train system.

Japanese Unexamined Patent Publication No. 2016-137876

The track of a train can be divided into a plurality of blocks. Here, when a track circuit is used, the block is a traveling path portion covered by the track circuit corresponding to the block. When an accelerator counter (axle counter) is used instead of the track circuit, this block is used as a traveling path portion covered by the accelerator counter corresponding to the block.

If a train is on a block, the track circuit covering the block will fall. On the contrary, when the train moves from the block to another block, the track circuit is lifted.

However, if the track circuit covering the block includes a turnout, the lock of the block section cannot be released until the train passes through the track circuit.

In that case, the train entering the block covered by the track circuit will always stop because the unlocking of the block section covering the track circuit cannot be released until the train passes through the track circuit. , Causes a decrease in train operation rate (operation efficiency).

Further, also in Patent Document 1, neither disclosure nor suggestion is made regarding the above-mentioned problems and means for solving the problems.

As a result of diligent studies by the inventor of the present application with respect to the above-mentioned problems, the present invention was conceived, and an object of the present invention is to secure safety for train operation accompanied by locking and unlocking of a traveling path. The above is to provide train control technology that improves the operating rate of trains.

The train control device according to the present invention includes a storage unit for storing train position information, a runway information that defines a train runway as a connected structure of blocks having a predetermined range, and a control state for each block, and a train. The block is provided with a processing unit that obtains the on-line position information from the position and driving direction information and the traveling path information and executes the locking and unlocking of the block based on the on-line position information and the control state of each block, and the block is a turnout. In the case of, the block is set by the opening direction of the turnout and the starting point of the turnout or the release point position determined by the vehicle contact limit of the train in the block, and the first logical block and the first logical block. It is composed of a second logical block adjacent to the first logical block, and when the processing unit detects that the train has passed the first logical block from the train position information, the block with the turnout is unlocked. It is characterized by locking.

According to the present invention, it is possible to improve the operating rate of a train while ensuring safety for the operation of a train accompanied by locking and unlocking of a traveling path.

It is a figure which shows the table which summarized the item which is related to the equipment, etc. existing on the runway (track). It is a figure explaining the method of subdividing (dividing) a block with a turnout into a logical block.

Hereinafter, examples of the present invention will be described as embodiments for carrying out the present invention with reference to the drawings.

However, the present invention is not limited to the examples shown below, and various modifications and modifications by those skilled in the art can be made within the scope of the technical idea disclosed in the present specification. Further, in the drawings for explaining the examples, those having the same function may be designated by the same reference numerals, and the repeated description thereof may be omitted.

FIG. 1 is a schematic view showing an example of the configuration of equipment on a traveling path (track) including the inside of a train as a target of train control according to an embodiment of the present invention.

The train 100 is equipped with an on-board device 102, and the on-board device 102 transmits and receives information to and from the ground system 101.

In FIG. 1, the track 103 on which the train travels is divided into certain sections in a form corresponding to the track circuit, and is represented as blocks 03G to 25G. Further, S0001C, S0101C and S0201C are the course names of each orbit.
Further, for example, station 1 (106) is located at the positions of blocks 05G and 15G, and station 2 (107) is located at the position of blocks 17G.

W0101a and W0101b indicate a turnout installed at each branch point composed of a block 03G or a block 13G and a line between them, and similarly, W0102a and W0102b are a line between the block 04G or the block 14G and both. W0103a and W0103b indicate the turnouts installed at each turnout composed of and, and W0103a and W0103b indicate the turnouts installed at each turnout composed of the block 14G or the block 23G and the line between them. ..
The branch path will be described later with reference to FIG. 3 by taking W0101b surrounded by a dashed-dotted line circle as an example.

FIG. 2 is a diagram showing a table summarizing items related to equipment and the like existing on a traveling path (track). In the train control according to the present invention, a CBTC (Communications-Based Train Control) method is used, but when the CBTC method fails, a non-CBTC method (a conventional track circuit or accelerator counter method) is used.

For example, regarding the "inside course", the "starting point" is block 12G, the "landing point" is block 15G, the "number" for identification indicates the course, S0101C-15G, and the turnout related to the "lock" is W0101. , W0102 and W0103, 13G, 14G and 15G for the block related to "signal control" in "signal control or check lock", and 13G and 14G for the block related to "path" in "path division lock" ( (For non-CBTC system) or 13G-A, 13G-NB, 13G-NC and 14G (for CBTC system).

Further, as an example of the "turnout", the "number" for identification is W0101a-W0101b, and the block related to "signal control" in "signal control or check lock" is 13G (in the case of non-CBTC method). Or 13G-NB, 13G-RB (in the case of CBTC method).
In the case of the CBTC method, 13G-A, 13G-NB, 13G-NC and 13G-RB indicate a logical block obtained by further dividing the block 13G, which will be described later.

FIG. 3 is a diagram illustrating a method of subdividing (dividing) a block with a turnout into logical blocks.
On the left side of FIG. 3, a part of the orbit 103 with the turnout 105 surrounded by the alternate long and short dash line is shown. This corresponds to the part circled by the alternate long and short dash line in FIG. In addition, in FIG. 3, the operation direction is shown not as a forward direction / a reverse direction but as an R direction / L direction (according to the paper surface) for convenience.

The track 103 is branched into two tracks, a main line and a lateral line, by the turnout mechanism of the turnout 105.

Release points 1 to 3 are positions determined according to the turnout and the vehicle contact limit on the main line and the lateral line. Here, the “clearance” indicated by the “x” mark in FIG. 3 indicates the vehicle contact limit point.

The release point 1 is localized (N) with respect to the main line and opposite (R) with respect to the side line in the L direction, and its position is set at the start position of the turnout. The release point position may be shifted to the front side of the start position of the turnout with a margin.

The release point 2 is localized (N) with respect to the main line in the R direction, and the position thereof is a position obtained from the vehicle contact limit point (clearance) with respect to the main line. The release point position may be shifted to a side beyond the obtained position with a margin.

The release point 3 is an inverse position (R) with respect to the main line in the R direction, and the position thereof is a position obtained from the vehicle contact limit point (clearance) with respect to the lateral line. The release point position may be shifted to a side beyond the obtained position with a margin.

According to the present invention, a block with a turnout is further subdivided into logical blocks to divide the block with a turnout, thereby speeding up the unlocking of the block section with the turnout and improving the operating rate of train operation.

On the right side of FIG. 3, a logical block in which a block with a turnout is further divided and subdivided is shown. Each logical block (13G-A, 13G-NB, 13G-NC, 13G-RB and 13G-RC) is a block with a turnout based on the opening direction of the turnout and the release points 1 to 3 above. It is subdivided and set as follows.

First, in the trajectory in the R direction, the trajectory of the main line from the start point of the block with the turnout to the release point 1 is defined as the logic block 13GA.

Next, a logic block 13G-NB is formed between the release points 1 and 2 and a logic block 13G-RB is formed between the release points 1 and 3 with a branch point.

Further, the trajectory of the main line from the release point 2 to the end point of the block with the turnout is defined as the logic block 13G-NC, and the trajectory of the lateral line from the release point 3 to the end point of the block with the turnout is the logic block 13G-RC. And.

As a result, the block with the turnout is composed of the logical block with the turnout (13G-NB and 13G-RB) and the logical block adjacent to the logical block (13G-A, 13G-NC and 13G-RC). Will be done. Further, the length of these logical blocks can be set shorter than the train length.

With this divided logic block, if a train traveling in the R direction passes through the logic block 13G-NB and enters the logic block 13G-NC, or passes through the logic block 13G-RB and enters the logic block 13G-RC. It is possible to unlock the block with the turnout by entering.

Further, if a train traveling in the L direction passes through the logic block 13G-NB on the main line side and enters the logic block 13G-A, or passes through the logic block 13G-RB on the siding side and passes through the logic block 13G-RB. If you enter A, you will be able to unlock the block with the turnout.

As described above, the present invention further subdivides a block with a turnout into logical blocks to speed up unlocking of a block section with a turnout and improve the operating rate of train operation. To enable.

Next, train control when a train operates on a track in which blocks are divided in a form including the above-mentioned logical blocks will be described.
The ground device 101 is based on the train position information received from the on-board device 102 of the train 100 and the train operating direction (forward or reverse direction) with respect to the identification code of the block corresponding to the head position in the traveling direction of the train 100. Creates and retains (stores) current position information. The train position information may be acquired not only by the on-board device 102 but also by the ground device 101 itself.

Further, in the ground device 101, the train 100 traveling in the R direction of FIG. 3 is a logical block with a turnout 105 (logical block 13G-NB or 13G-RB shown in FIG. 3) based on the on-line position information. When it is detected that the player has passed the release point position (release point 2 or release point 3 shown in FIG. 3) and entered the next block (logic block 13G-NC or 13G-RC shown in FIG. 3), the relevant block is detected. Unlock the logical block section with the turnout 105. The passage detection of the release point position of the train is not limited to the ground device 101, but may be detected by the on-board device 102 or a turnout at the site.

Here, in order to perform the train control function (operation mode) for train operation according to the present invention, the ground device 101 is, for example, from a storage unit and a processing unit (both) as a part of its configuration. A train control device configured (not shown) can be provided.
