Description

Description: Object of the Invention [Industrial application field] The present invention relates to a route control method and a route control device in a ground-driven primary magnetic levitation railway.

[Prior Art] Conventionally, block control has been performed in order to prevent collision between trains and to shorten the train operation interval as much as possible. Blocking control is a control method in which only one person is present in a given block section and safety is ensured by preventing the following train from entering.In general electric railways, fixed block and moving block are known. ing.

The fixed route is based on only the position of the preceding train, and the moving route is controlled by signal display or ATC in consideration of the speed of the following train. In any of the control methods, a configuration in which the position of the preceding train is detected by a track circuit is adopted, and the track circuit is configured for each block section predetermined based on the braking distance or idle running distance of the succeeding train. I was Therefore, the unit of the block section is fixed even though it is a moving block.

On the other hand, in the terrestrial primary drive type magnetic levitation railway, when performing block control, in addition to conditions such as braking distance, there is also a condition that only one train can enter the feeding section by one power conversion substation. It needs to be satisfied. Therefore, the unit of the block section is determined based on the feed section by the power conversion substation.

[Problems to be Solved by the Invention] For this reason, it is necessary to increase the number of power conversion substations in order to shorten the block section in the terrestrial primary drive type maglev train by applying the block control in the conventional general electric railway. Therefore, there is a problem such as an increase in equipment cost, and it has been difficult to realize. As a result, in the magnetically levitated railway of the ground primary drive type, the block section becomes extremely long, and there is a problem that it is not possible to realize efficient operation at train operation intervals particularly near a station or the like.

On the other hand, recently, as a propulsion method for the terrestrial primary drive type magnetic levitation railway, a plurality of switches provided on the electric wire between the power conversion substations are controlled to improve the propulsion efficiency, etc. Propulsion control has been proposed. However, this is only a proposal as a propulsion system on an experimental line, and a technology related to block control required for a practical line has not been invented yet.

It is also necessary to consider security measures in the event of a feeding failure in the primary levitation magnetic levitation railway.

The present invention is a terrestrial primary drive type magnetic levitation railway,
In order to control the operation at efficient train operation intervals, we apply the proposed propulsion control of the feeder section variable type, and pay due attention to the safety aspects of the practical line, a new and optimal The present invention has been completed for the purpose of providing a route control method and a route control device in a ground-based primary drive type magnetic levitation railway.

Configuration of the Invention [Means for Solving the Problems] A block control method for a ground-based primary drive type magnetic levitation railway according to the present invention, which has been made to achieve the above object, comprises two or more systems that are excited from separate feeding systems. Induction coil groups are alternately arranged on the ground, and a plurality of boundary section switches for varying the boundaries of the feeder sections from adjacent power conversion substations are provided for each of the feeder systems. Ground primary drive system for controlling train operation while changing the switching state of the switch as the train progresses, and controlling blockage so that no two or more trains exist in the feeder section by the same power conversion substation A block control method in a magnetic levitation railway, comprising determining a feeding section of each power conversion substation for each feeding system from an open / closed state of each boundary segment switch, and different power conversion when compared between the feeding systems. Substation When Interval overlap, adopts the structure which is characterized in that the end conditions for the block section determines the end closer to the succeeding train of the overlapping portion.

In addition, the block control device in the primary terrestrial drive type magnetic levitation railway of the present invention includes two or more induction coil groups that are alternately arranged on the ground and are excited from separate feeding systems, and an adjacent power conversion substation. A plurality of boundary section switches that are arranged between the power supply sections and change the boundaries of the feeder sections for each feeder system according to their own open / closed state; train position detecting means for detecting the position of the train; Switching state changing means for changing the opening / closing state of the boundary section switch according to the direction and the position, and from the opening / closing state of each boundary section switch, the feeding section of each power conversion substation for each feeding system. If the feeding sections of different power conversion substations overlap when the feeding sections for different feeding systems are compared with each other, the closer to the subsequent train of the overlapping portion, If the end on the side is the end condition when determining the feeder section, Based on the end conditions of the feeder section and the direction and position of the train, based on the end conditions of the feeder section, the following trains so that there are no more than two trains in the feeder section by the same power conversion substation And a block control means for executing a block control on.

[Operation] According to the block control method in the terrestrial primary drive type magnetic levitation railway of the present invention, a configuration is adopted in which two or more induction coil groups excited from separate feeding systems are alternately arranged on the ground. Accordingly, even when one feeder system fails and train operation control by the feeder system becomes impossible, the train operation control can be performed by another feeder system. Also,
The configuration that variably controls the boundaries of the feeder sections from adjacent power conversion substations while changing the open / closed state of multiple boundary section switches as the train progresses, enables efficient operation of the train, Second, it can save power.

In performing such a variable boundary control of a feeder section that is excellent in terms of security and efficiency, for example, when there is a difference in the switching time when the switching state of the boundary segment switch is changed, a different power supply There may be times when feeder sections overlap. In addition, even if the induction coil groups excited by different feeding systems are alternately arranged, a different power supply overlapping section having a half of the induction coil length may be generated just above the boundary section switch.

However, in the block control method of the present invention, the feeder section of each power conversion substation for each feeder system is determined based on the open / closed state of each boundary section switch, and different power conversion substations are used when the feeder systems are compared. If the feeder section overlaps, the end of the overlapping section nearer to the next train is used as the end condition when determining the section to be closed. Secure and efficient train operation intervals can be ensured accurately while satisfying the essential block control conditions of the ground-based primary drive type magnetic levitation railway, which controls the block so that there are no more than two trains in the section. . Also,
The configuration to determine the overlapping section operates so as to ignore the power failure section that occurred partially, so that it is possible to perform block control corresponding to the section that should be truly blocked, and there is no train at all,
In addition, it is possible to prevent the occurrence of a blank section in which the user is blocked even though there is no need to block.

Further, in the block control device in the terrestrial primary drive type magnetic levitation railway of the present invention, the induction coil group of two or more systems, the plurality of boundary section switches, the train position detecting means, and the switching state changing means having the above-described configuration are provided. Efficient and efficient train operation from the viewpoint of power saving, and by adopting the feeder section determining means for each feeder system, feeder section end condition determining means and block control means also having the above-described configuration, It is excellent in efficiency and safety, and it is possible to accurately secure the optimal train operation interval for the ground-based primary drive type magnetic levitation railway with no blank section.

In the final block control using the block control method and the block control device of the present invention, as shown as case 1 in FIG. When the train is located within the section, only the block section 1 shown in the drawing, that is, only the single feeder section where the preceding train is on the line is blocked. Further, as shown in Case 2, when the preceding train is located in the different power supply overlapping section due to the first power conversion substation and the second power conversion substation, the block section 2 shown in FIG. All feeder sections by the second power conversion substation are blocked. Then, as shown in Case 3, the second
In the case where the preceding train is located in a single feeder section of the power conversion substation, the block section 3 shown in the figure is closed, and the rear end of the different power supply overlapping section is the end.

However, the present invention is not limited to this, and yet another feature necessary for taking advantage of these features is that the block control devices CTL01, CTL12
In particular, a unique method of determining a block section is adopted in the block control by the system, and the system is completed as a whole.

Therefore, a method of determining the characteristic block section will be described with reference to the flowchart of FIG. 4 using the block control device CTL12 as an example.

The block control device CTL12 is a unit BSS12 between power conversion substations.
Information Qos concerning the open / closed state of each of the boundary segment switches OSA, OSB, and OSC in the unit is fetched (step S1), and each feeder system L
Feeding section for A, LB, LC by first power conversion substation SS1
The power supply section SEC2 A, SEC2 B, SEC2 C by SEC1 A, SEC1 B, SEC1 C and the second power conversion substation SS2 is determined (step S2). In the present embodiment, the determination in step S2 also has one feature. It is simply each boundary segment switch OSA, OSB,
In addition to referring to only the information Qos relating to the open / closed state of the OSC, in addition to this information Qos, each system is determined to be a range where power can be fed starting from one of the power conversion substations SS1 and SS2. . Therefore, if there is a section corresponding to a power failure in each system, it is correctly determined as a power failure section.

Then, the feeder section SEC1 by the first power conversion substation SS1
A, SEC1 B, SEC1 C are compared, and the end condition EPfor SS2 closest to the second power conversion substation SS2 is calculated (step S

S5).

If the different power supply overlapping section SEC1 & 2 does not exist, the block condition determining end condition EPfor CTL in the unit BSS12 between the power conversion substations is changed to the feeding section of the first power conversion substation SS1.
The end condition Pfor SS2 of SEC1 A, SEC1 B, and SEC1 C is determined (step S6).

On the other hand, if different power supply overlapping section SEC1 & 2 exists,
The end condition EPfor CTL for determining a block section in the unit BSS12 between power conversion substations is set to the second end that is the end of the different power supply overlapping section SEC1 & 2 and closer to the subsequent train TRnext.
The end condition Pfor SS1 of the feeder section SEC2 A, SEC2 B, SEC2 C of the power conversion substation SS2 is determined (step S7).

Then, based on the block section determination end condition EPfor CTL determined in step S6 or step S7, further based on information on the preceding train TRforward, information QDIA on operation schedules and the like, information QST on station position, etc. Then, a block control process is executed to prevent the presence of two or more trains in the feeder section by the same power conversion substation (step S8).

The switching status of each of the boundary segment switches OSA, OSB, and OSC of No. 1 to No. 3 in the unit BSS12 between power conversion substations is determined by the feeder system LA, L
Assume that B and LC are in the state shown in the middle table. In the upper part of the figure, the closed circle indicates “closed (C)”,
Open circles represent “open (O)”.

In this case, SEC1 A is set to section 1 by step S2 described above.
~ Interval 3, SEC1 B is determined as Interval 1-2, SEC1 C is determined as Interval 1, SEC2 A is determined as Interval 4, SEC 2 is determined as Interval 3-Interval 4, and SEC2 C is determined as Interval 4. Will be.

Then, each section 1 serving as a basis for the determination processing in step S5
The feeding state in section 4 is determined as shown in the lower part. In the lower part, the corresponding power conversion substations are represented by symbols “SS1” and “SS2”, and a power outage state where no power is supplied from any of them is represented by symbol “X”.

That is, in the section 1, since each of the systems A, B, and C is fed from the first power conversion substation SS1, it is determined that the system is the sole feeding section SEC1 by the first power conversion substation SS1, and the section 4 Is also determined to be a single feeder section SEC2 by the second power conversion substation SS2. On the other hand, for section 2, system A, B
The system is fed from the first power conversion substation SS1, but only the C system is not fed from any of the power conversion substations SS1 and SS2. It is determined that it is a single feeder section SEC1 by SS1.
And, for section 3, the A system is the first power conversion substation
Since power is supplied from SS1 and the system B is supplied from the second power conversion substation SS2 and the system C is not supplied from any of the power conversion substations SS1 and SS2, it is determined that the different power supply overlapping section SEC1 & 2. .

As a result, in the example of FIG. 5, the determination in step S5 is “YE
S '', the process proceeds to step S7, and the block section determination end condition EPfor within the power conversion substation unit BSS12.
The second power conversion substation SS, where CTL is the end of the different power supply overlapping section SEC1 & 2 and is the end close to the next train TRnext
2 Feeding section SEC2 A, SEC2 B, SEC2 C end condition Pfor SS1
Is determined.

In the subsequent block control process in step S8,
As described in the section of [Action] based on FIG. 1, the block section is determined based on the position PTR of the preceding train TRforward, and the stepless speed control instruction signal SATC for the ATC of the succeeding train TRnext is determined. Is output.

As described above, according to this embodiment, the failure occurs in the boundary segment switches OSA, OSB, and OSC due to the adoption of two or more feeder systems called the seamount triple feeder system, and a partial power failure occurs. Even if a section occurs, there is no hindrance to train operation. In addition, a configuration is employed in which the switch control devices OSC01 and OSC12 perform variable control of the feeder section, thereby enabling highly efficient train operation control. Further, the advantage of this boundary variable control is that the block section can also be made variable, which also enables the succeeding train to proceed further forward. By adopting a unique block control, especially a unique block section determination method, this system was completed as a whole, enabling high-efficiency control in terms of train operation intervals, and secondary power consumption. This enables highly efficient operation control from the viewpoint of safety, and sufficient and accurate considerations are given to safety.

As a result, the magnetic levitation railway, which is expected as a transportation system for the next generation, can greatly meet the demands for efficiency and security in practical use of a system employing the primary ground drive system.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various embodiments may be employed without departing from the scope of the invention.
