Abstract

PURPOSE:To make smooth train operation possible by extending a border toward the side of a preceding current feeding section, when a train is not in the assigned sections of a substation which divides a line into a plurality, and by extending the border to the side of a preceding train, till the distance up to the border being on the side of the preceding train becomes a stoppable distance, when a train is on the line. CONSTITUTION:Each of a plurality of substations 1, 2,... along a line has a plurality of current feeding sections assigned. A border of a current feeding section assigned is moved upstream or downstream, by causing a border varying switch controller 9 to control border varying switches 5. A plurality of train position detecting devices 9 along the line detect the existence of trains in each current feeding section every moment, and input them into the border varying switch controller 9. When a train is not in sections assigned, the upstream-side border is moved to the upstream side. Besides, when a preceding train 6 and the following train 7 are on the line, for example, downstream borders of individual trains 6 and 7 are extended up to stoppable distances of the trains 6 and 7. Consequently, individual trains are operated smoothly at specified speeds.

Field of the Invention The present invention arranges a plurality of substations so as to divide a line, and changes the boundaries between the substations by switching boundary variable switches to control the power supply range of each substation. As a result, it is possible to realize smooth train operation on a magnetically levitated railway that operates smoothly, without being affected by route conditions or substation installation conditions, and with a simple boundary variable algorithm. The present invention relates to a boundary variable switch control method and device in a magnetic levitation railway.

2. Description of the Related Art Recently, in the field of railways, a plurality of substations are arranged so as to divide a line, and the boundaries between the substations are changed by switching boundary variable switches to change the power supply range of each substation. Magnetically levitated railways are being put to practical use that can be operated smoothly by controlling them.

In this type of magnetic levitation railway, the speed of the train is controlled not by controlling the train itself but by controlling the power supply frequency on the track side. The control of the power supply frequency is performed by using the converter installed in each substation.

In other words, controlling the speed of the train means controlling the converter of the substation. Therefore, only one train can be supplied from one substation. Then, on the actual route, the entire process is divided into a plurality of substations and a plurality of trains are operated.

By the way, in such a magnetic levitation railway, when two different substations are currently supplying power to different trains, a train behind the train enters the substation supplying power to the train ahead. Can not. Therefore, even if the trains are sufficiently distant from each other, the train at the rear must stop at the boundary with the substation at the front.

Further, when the train is traveling at a speed v, if the normal deceleration is a, in order to stop, S = v ² / (2
The distance a) is required. Therefore, in order to stop at the boundary, it is necessary to decelerate before the position of v ² / (2a) before the boundary.

However, because of the boundaries between substations,
Decelerating the train or stopping the train is a disorder of the schedule. Further, in order to prevent the schedules from being disturbed, it is necessary to keep a sufficient schedule interval from the beginning, which prevents efficient train operation.

The boundary variable switch control realizes smooth train operation by efficiently changing the boundaries between the substations without decelerating or stopping at the boundaries of the substations.

The conventional boundary variable switch control is performed for each substation, and roughly follows the boundary variable algorithm as follows. (A) If a train is located at the self substation and a preceding train is also located at the next substation, the position of the train located at the self substation is the same as that of the next substation. The boundary between the substation and the next substation is extended to the side of the next substation (extension) before it has to slow down to stop before the boundary.

(B) There is no train at the substation,
If there is a train at the front substation, extend the boundary between the substation and the front substation to the front substation side (welcome).

(C) Even if there is a train at the substation,
If there is no train at the next substation, or if there is no train at either the own substation or the front substation, the boundary is not changed.

However, in such a conventional control method, when the distance between the substations is shorter than the distance at which deceleration is started due to the boundary, or when the trains are on the way between the short substations, the distance between the trains is sufficient. There is a problem that subsequent trains will be slowed down by the substation boundary even if they are separated from each other.

Hereinafter, such a problem will be described with reference to FIG. FIG. 6 is a schematic diagram showing a train position and a state of the boundary variable switch when the boundary variable switch is controlled by the conventional method.

As shown in FIG. 6, the substation 1, the substation 2, the substation 3, and the substation 4 are arranged so as to divide the route. The substation 1, the substation 2, the substation 3, and the substation 4 is switched by the boundary variable switch 5 through the boundary variable switch 5, and thrust is obtained by the power supplied from the substation 1, the substation 2, the substation 3, and the substation 4 through the boundary variable switch 5, and the preceding train 6 and the succeeding train Train 7 is designed to run.

First, in FIG. 6A, the preceding train 6
However, when the power supply range of the substation 3 shifts to the power supply range of the substation 4, the substation 3 is in a state where no train is present. Then, since the train is located at the front substation 2, the substation 3 tries to move the boundary between the front substation 2 and the front substation 2 in the conventional boundary variable algorithm. Figure 6
In (a), since the boundary between the substation 2 and the substation 3 is just at the substation 2 side, the boundary of the substation 3 is not changed in this state.

Further, in FIG. 6B, for the succeeding train 7, the point A directly below the substation 3 is the boundary position, and when the distance between the substation 2 and the substation 3 is short, the succeeding train 7 and the point A are shown. When the distance is shorter than the stoptable distance by m, the succeeding train 7 is forced to decelerate. In the conventional boundary variable algorithm, the substation 3 does not change the boundary of the substation 3 because the condition for changing the boundary is not satisfied.

Further, in FIG. 6 (c), the succeeding train 7
However, when moving from the substation 2 to the power supply range of the substation 3, the substation 3 has the succeeding train 7, the next substation 4 has the preceding train 6, and the succeeding train 7 is the substation. 3 and substation 4
Since the distance to the boundary between the substations is short and the vehicle is decelerating, the boundary variable switch 5 is controlled so as to move the boundary between the substation 3 and the substation 4 to the substation 4 side. After the boundary variable switch 5 is controlled, the deceleration applied to the succeeding train 7 is released.

In FIG. 6, solid squares indicate that the boundary variable switch 5 is closed, and squares indicate that the boundary variable switch 5 is open. As described above, in the conventional boundary variable algorithm, even if the distance between the preceding train 6 and the following train 7 is sufficient, in the state shown in FIG. 6B, deceleration is caused by the substation boundary. There is a problem.

[0019]

As described above, in the conventional boundary variable switch control method in the magnetic levitation railway, when the substation interval is shorter than the distance at which deceleration is started by the boundary, a short substation is inserted. There was a problem that when the trains were in the form of trains, even if the trains were sufficiently separated from each other, the following trains received a deceleration due to the substation boundary.

An object of the present invention is to control the boundary variable switch so as to secure a required distance for each train, or to control the boundary variable switch so that the boundary variable switch position after passing the train is a boundary. An extremely reliable variable boundary switch control method for a magnetic levitation railway that can realize smooth train operation without being affected by route conditions or substation installation conditions and by a simple boundary variable algorithm. And to provide a device.

[0021]

In order to achieve the above-mentioned object, a plurality of substations are arranged so as to divide a route, and the boundaries between the substations are changed by switching boundary variable switches. In a method of controlling a boundary variable switch in a magnetic levitation railway, which smoothly operates a train by controlling a power supply range of a substation, first, in the invention according to claim 1, in the invention according to claim 1, If there is no train in the section, the boundary between the substation and the substation in front of it is extended to the front substation side, and the substation in which the train is in the section is connected to the preceding train. The boundary variable switch is controlled to extend the boundary to the side of the preceding train when the distance to the boundary is less than the stopable distance of the train.

Further, in the invention according to claim 2, when the train is not present in the corresponding section of the line divided for each substation, the substation on the boundary between the substation and the substation on the front side is the front substation. For substations that extend to the station side and have trains in the relevant section, when the trains pass the boundary variable switch,
The boundary variable switch is controlled so that the boundary variable switch position becomes a boundary.

On the other hand, by arranging a plurality of substations so as to divide the route and changing the boundary between the substations by switching the boundary variable switch to control the power supply range of each substation, a smooth train In the control device for the boundary variable switch in the magnetic levitation type railway that performs the operation, first, in the invention according to claim 3, train position detecting means for detecting the position of the train and outputting a signal, and train position detecting means Train position recognition means for recognizing the position of the train by the output signal, boundary position recognition means for recognizing the boundary position by the state of the boundary variable switch, train position recognized by the train position recognition means, and recognition by the boundary position recognition means If there is no train in the corresponding section of the line divided for each substation, the boundary between the substation and the substation in front of If the distance to the boundary with the preceding train is less than the stopable distance of the train, the boundary will be extended to the preceding train side. Boundary position determining means for determining the boundary position, and a boundary variable switch for controlling the boundary position determined by the boundary position determining means to be selected, and a control output for controlling opening / closing control signal to the boundary variable switch. And means.

Further, in the invention according to claim 4, train position detecting means for detecting the position of the train and outputting a signal, and train position recognizing means for recognizing the position of the train by the output signal from the train position detecting means. , The boundary position recognizing means for recognizing the boundary position by the state of the boundary variable switch, and the train position recognized by the train position recognizing means and the boundary position recognized by the boundary position recognizing means are divided for each substation. If there is no train in the relevant section of the route, the boundary between the substation and the substation in front of it is extended to the front substation side, and the substation in which the train is Is a boundary position determined by the boundary position determining means and a boundary position determining means for determining the boundary position so that the boundary variable switch position becomes the boundary when Select boundary variable switch controlled so, and a control output unit for controlling outputting a switching control signal to the boundary variable switch.

[0025]

Therefore, first, in the boundary variable switch control method and apparatus for the magnetic levitation railway according to the first and third aspects of the present invention, the train is present in the corresponding section of the line divided for each substation. If not, extend the boundary between the substation and the front substation to the front substation side (pick up), and when the distance to the boundary with the preceding train is less than the stopable distance of your train, move the boundary to the preceding train. By extending to the side, the distance to the train boundary will always be longer than the stoppable distance unless the distance between the trains is too short, resulting in the deceleration or stop of the following train at the substation boundary. Never.

Further, in the boundary variable switch control method and apparatus for the magnetic levitation railway according to the inventions of claims 2 and 4, the train is not present in the corresponding section of the line divided for each substation. In this case, the boundary between the substation and the front substation is extended (greeted) to the front substation side, and when the train passes through the variable boundary switch, the boundary variable switch that has passed is opened and the position is defined as the boundary. As a result, the distance to the train boundary is almost equal to the distance between trains. Therefore, if the distance between trains is longer than the stoppable distance, the distance to the train boundary is always larger than the stoppable distance. It will also be longer and will not slow down or stop subsequent trains due to substation boundaries.

An open / close control signal is output to the variable switch 5.

As described above, the distance to the train boundary is always longer than the stoptable distance + the margin distance unless the distance between the trains is too short. Therefore, the train decelerates or stops following the substation boundary. Is not done.

Next, this point will be described more specifically with reference to FIG. FIG. 4 is a schematic diagram showing a train position and a state of the boundary variable switch 5 when the boundary variable switch 5 is controlled by the above method.

In FIG. 4 (a), when the preceding train 6 moves from the power supply range of the substation 3 to the power supply range of the substation 4, the substation 3 is in a state where no train is present in the corresponding section. Therefore, the substation 3 moves the boundary between the substation 2 and the front substation 2 to the front substation 2 side, and the state shown in FIG. 4B is obtained.

In FIG. 4C, for the succeeding train 7, when the point A directly below the substation 3 is the boundary position, the substation 2
~ When the distance between the substations 3 is short, before the distance between the following train 7 and the point A becomes shorter than the stoppable distance + the margin distance, the substation 3

Since the succeeding train 7 extends the boundary before the distance to the boundary becomes shorter than the stoptable distance + surplus distance, the distance to the boundary is always longer than the stoptable distance + surplus distance. Therefore, the following train 7 at the substation boundary
Will not slow down or stop.

In FIG. 4, the solid squares indicate that the boundary variable switch 5 is closed, and the squares indicate that the boundary variable switch 5 is open. As described above, in the present embodiment, the plurality of substations 1 and 2 are arranged so as to divide the route, and the boundary variable switch 5 is provided at the boundary between the substations 1 and 2.
The position of the trains 6 and 7 is controlled by the control device of the boundary variable switch in the magnetic levitation railway that smoothly operates the trains 6 and 7 by changing the power supply ranges of the substations 1 and 2 by changing the positions of the trains 6 and 7. Position detecting device 8 for detecting a signal and outputting a signal, a train position input means 91 for inputting an output signal from the train position detecting device 8, and a boundary variable switch state input means for inputting an open / closed state signal of each boundary variable switch 5. 92, a train position recognition means 93 for recognizing the positions of the trains 6, 7 by an output signal from the train position input means 91, a boundary position recognition means 94 for recognizing a boundary position by an output signal from the boundary variable switch state input means 92, Roads divided for each substation based on the train position recognized by the train position recognition means 93 and the boundary position recognized by the boundary position recognition means 94. If there is no train in that section, the boundary between the substation and the substation in front of it is extended to the front substation side, and if the train is in that section, the preceding train 6 The distance to the boundary with is own train 7
When the distance is equal to or less than the stopable distance + the allowance distance (fixed), the boundary position is determined by the boundary position determining means 95 and the boundary position determining means 95 for determining the boundary position so as to extend the boundary toward the preceding train 6 side. The boundary variable switch controller 9 including the switch selecting means 96 for selecting the boundary variable switch 5 to be controlled as described above and the switch control output means 97 for outputting the opening / closing control signal to the boundary variable switch 5 selected by the switch selecting means 96. It is composed.

Therefore, it is possible to realize smooth train operation without being influenced by the route conditions and the installation conditions of the substation and by the simple boundary variable algorithm.
As a result, the distance to the train boundary will always be longer than the distance that can be stopped unless the distance between trains is too short. When the train is short, when the train is in the form of sandwiching a short substation, even if the trains are sufficiently separated,
It is possible to solve the problem that the following train 7 receives a deceleration due to the substation boundary.

Next, a second embodiment of the present invention will be described. Since the structure of the boundary variable switch control device in the magnetic levitation railway according to the second embodiment is similar to the structure of FIGS. 1 and 2 described above, its illustration is omitted here and only different parts will be described here. .

That is, this embodiment is different from the first embodiment only in the function of the boundary position determining means 95 in the boundary variable switch controller 9. The boundary position determining means 95 of the present embodiment corresponds to a line divided for each substation based on the train position recognized by the train position recognizing means 93 and the boundary position recognized by the boundary position recognizing means 94. If there is no train in the section, extend the boundary between the substation and the substation in front of it to the substation side in front, and for the substation in which the train is in the section,
When the train passes through the boundary variable switch 5, the boundary position is determined so that the boundary variable switch position becomes the boundary.

Next, a control method in the boundary variable switch control device of the present embodiment having the above configuration will be described with reference to the flow chart shown in FIG. 3 (b). In FIG. 1, the train position detection device 8 detects the positions of the trains 6 and 7, and the signals thereof are input to the boundary variable switch controller 9. The boundary variable switch controller 9 recognizes the positions of the trains 6 and 7 by the input signal from the train position detecting device 8,
Opening / closing control of the variable boundary switch 5 is performed according to the situation.

That is, in the boundary variable switch controller 9, the train position input means 91 inputs the train position signal, and the boundary variable switch state input means 92 inputs the open / closed state signal of each boundary variable switch 5.

Next, the train position recognizing means 93 recognizes the positions of the trains 6 and 7 by the train position signal from the train position inputting means 91, and the boundary position recognizing means 94 recognizes the boundary variable switch state inputting means 92. The boundary position is recognized by the open / close state signal of each boundary variable switch 5 from.

Next, in the boundary position determining means 95, the lines divided for each substation based on the train position recognized by the train position recognizing means 93 and the boundary position recognized by the boundary position recognizing means 94. If there is no train in that section, the boundary between the substation and the substation in front of it is extended to the front substation side, and if the train is in the section, the When the variable switch 5 is passed, the boundary position is determined so that the boundary variable switch position becomes the boundary.

Then, the switch selection means 96 selects the boundary variable switch 5 to be controlled so as to reach the boundary position determined by the boundary position determination means 95, and the switch control output means 97 further selects the selected boundary. An open / close control signal is output to the variable switch 5.

As described above, the distance to the train boundary is always longer than the stoptable distance + the margin distance unless the distance between the trains is too short. Therefore, the train decelerates or stops following the substation boundary. Is not done.

Next, this point will be described more specifically with reference to FIG. In FIG. 5A, the preceding train 6
However, when the power supply range of the substation 3 shifts to the power supply range of the substation 4, the substation 3 is in a state where no train is present. Therefore, the substation 3 moves the boundary with the front substation 2 to the front substation 2 side, and becomes a state as shown in FIG. 5B.

In FIG. 5 (c), when the train passes through the variable boundary switch 5, control is performed so that the variable boundary switch 5 that has passed through becomes the boundary. Therefore, the boundary between the substations 3 and 4 is the boundary variable switch 5 located in the immediate rear of the preceding train 6. That is, the boundary for the succeeding train 7 is almost equivalent to that of the preceding train 6, and if the distance between the preceding train 6 and the succeeding train 7 is sufficient, the succeeding train 7 will not decelerate.

In FIG. 5, 1 indicates that the boundary variable switch 5 is closed, and □ indicates that the boundary variable switch 5 is open. As described above, in the present embodiment, the plurality of substations 1 and 2 are arranged so as to divide the route, and the boundary variable switch 5 is provided at the boundary between the substations 1 and 2.
The position of the trains 6 and 7 is controlled by the control device of the boundary variable switch in the magnetic levitation railway that smoothly operates the trains 6 and 7 by changing the power supply ranges of the substations 1 and 2 by changing the switching of Position detecting device 8 for detecting a signal and outputting a signal, a train position input means 91 for inputting an output signal from the train position detecting device 8, and a boundary variable switch state input means for inputting an open / closed state signal of each boundary variable switch 5. 92, a train position recognition means 93 for recognizing the positions of the trains 6, 7 by an output signal from the train position input means 91, a boundary position recognition means 94 for recognizing a boundary position by an output signal from the boundary variable switch state input means 92, Roads divided for each substation based on the train position recognized by the train position recognition means 93 and the boundary position recognized by the boundary position recognition means 94. If there is no train in that section, the boundary between the substation and the substation in front of it is extended to the front substation side, and if the train is in the section, the Boundary position determining means 95 that determines the boundary position so that the boundary variable switch position becomes the boundary when passing through the variable switch 5, and the boundary variable switch that controls the boundary position to be the boundary position determined by the boundary position determining means 95. Switch selection means 96 for selecting 5;
Switch control output means 9 for outputting an opening / closing control signal to the boundary variable switch 5 selected by the switch selection means 96.
And a boundary variable switch controller 9 of 7.

Therefore, it is possible to realize smooth train operation without being influenced by the route conditions and the installation conditions of the substation and by the simple boundary variable algorithm.
As a result, the distance to the train boundary is almost equal to the distance between trains. Therefore, if the distance between trains is longer than the distance that can be stopped + the surplus distance, the distance to the train boundary is stopped at any time. It becomes longer than possible distance + margin distance,
As in the past, when the distance between substations is shorter than the distance at which deceleration starts due to boundaries, when trains are in the form of sandwiching a short substation, even if the trains are sufficiently separated, subsequent trains 7
It is possible to solve the problem that is subject to deceleration due to substation boundaries.

The present invention is not limited to the above embodiments, but can be implemented in the same manner as described below. In the first embodiment, the boundary position determining means 95 divides each substation based on the train position recognized by the train position recognizing means 93 and the boundary position recognized by the boundary position recognizing means 94. If there is no train in the corresponding section of the route, the boundary between the substation and the substation in front of it is extended to the front substation side, and the preceding train is the substation where the train is in the section. The case where the boundary position is determined so as to extend the boundary to the side of the preceding train 6 when the distance to the boundary with 6 is equal to or less than the stoptable distance of the own train + the allowance distance has been explained. However, it is not an essential requirement for the present invention.

A plurality of substations are arranged so as to divide the route, and a boundary between the substations is changed by switching a boundary variable switch to control a power supply range of each substation, thereby smoothing the operation. In a controller for a boundary variable switch in a magnetically levitated railway that operates a train, a train position detecting unit that detects the position of the train and outputs a signal, and a train position is recognized by an output signal from the train position detecting unit. A train position recognition means, a boundary position recognition means for recognizing a boundary position based on the state of the boundary variable switch, a train position recognized by the train position recognition means, and a boundary position recognized by the boundary position recognition means. Based on the above, if there is no train in the corresponding section of the line divided for each substation, the boundary between the substation and the substation in front of At the substation where the train is located in the relevant section, the boundary is extended to the preceding train side when the distance to the boundary with the preceding train is less than the stopable distance of the own train. Boundary position determining means for determining the boundary position, and a boundary variable switch for controlling the boundary position determined by the boundary position determining means to be selected, and a control for outputting an opening / closing control signal to the boundary variable switch.
