Description

[0001] Train speed improvement system and method therefor [

[0001] The present invention relates to a train speed improvement system and method, and more particularly, to a railway speed improvement system and a train speed improvement system capable of improving a train speed as a whole by shortening the time required for starting with a simple and efficient structure .

The purpose of the automatic train operation of the train is to ensure that the train is operated according to the set target speed in each service area, and that it is stopped accurately and safely at the designated location in the station and that the service is efficient and safe between the stations .

The automatic operation of such a train can be carried out without a driver. Even if there is a driver, the driver does not interfere principally with the operation of the train, and only a minimum task of performing the braking of the train is given only in an emergency situation.

On the other hand, in the case of the Communication Based Train Control (CBTC) which is operated by wireless communication, the protection of the train is performed by Automatic Train Protection (ATP) Is carried out in an Automatic Train Operation (ATO).

The ATP sets the ATP speed profile or ATP rate limit considering various factors such as the speed limit of the train in each section, the stopping point according to the movement authority, and the safety braking model. The speed limit is transmitted to the ATO. The ATO generates the ATO speed profile in consideration of various factors such as the ride comfort and the tack factor, so that the limit does not exceed the limit when the train is operated.

The train then measures the current speed and commands the train to decelerate to follow the ATO velocity profile the train was created in. As a result, the train travels according to the generated ATO velocity profile.

1 is a graph for explaining control of a train speed according to the prior art.

In FIG. 1, T1 is the current time, Tw is the time when the train exceeds the ATP speed limit for warning (ATP speed limit for warning), T2 is the time when the train is in the ATP speed limit for emergency braking It points to overtime.

A train typically travels along an ATO velocity profile (not shown), but if the ATP velocity profile or ATP rate limit is exceeded, the ATP can trigger an emergency break to eventually stop the train.

In general, the ATP rate limit is the ATP rate limit for alarms and the ATP rate limit for emergency braking, and the ATP rate is limited to the driver or manager Deliver a warning.

However, if the speed of the train exceeds the ATP speed limit for emergency braking due to no follow-up due to the delivered warning, the ATP activates emergency braking to stop the train.

That is, if the train travels at the train speed as shown in FIG. 1, the ATP sends a warning signal to the driver or manager at Tw, and the ATP at T2 sends the emergency braking command to the train. Then, the train is stopped by emergency braking.

Thus, in a typical train automatic transmission system, based on the ATP rate limit generated by the ATP, the ATO generates an ATO velocity profile, and a propulsion or braking command such that the train follows the ATO velocity profile without exceeding the ATP speed limit To ensure the safety of the train.

In the above system, it is general to give a large safety margin when ATO velocity profile is generated so as not to cause emergency braking during the operation of the train.

Therefore, it is inevitable to adopt a conservative driving method in which the interval between the set value and the allowable limit increases. In other words, although the train can be operated at a higher speed, it is inevitable to operate at a lower speed because of the possibility of emergency braking.

In this type of operation in the conventional system, the number of times the train is operated on the line is reduced, resulting in an inefficient operating efficiency in terms of economy.

Accordingly, measures for solving such problems are disclosed in Korean Patent Office No. 10-2009-0081848, Korean Patent Office Application No. 10-2011-0107128, Korean Patent Office No. 10-2013-0014544, Korean Patent Office Application No. 10-2013-0101975, and the like.

However, in the case of the related art including the above-mentioned document, in order to improve the train speed, a rather complicated system must be applied. In this case, considering that a lot of loss can be generated both costly and controllably , It is required to develop a technology that can improve the overall train speed by shortening the start-up time by a simple and efficient structure.

Referring to these drawings, the train speed improvement system according to the present embodiment is a simple and efficient structure that can shorten the time required for starting, thereby improving the train speed as a whole. The train speed improvement system includes a plurality of unit trains 100a to 100c , Docking modules 111 and 112 provided in the unit trains 100a to 100c and docked or undocked with neighboring unit trains 100a to 100c and a controller 150 for controlling them have.

The unit trains 100a to 100c are units constituting a train. Of course, the unit trains 100a to 100c do not mean one train, but can be implemented with two or more train trains.

The unit trains 100a to 100c are schematically shown in Fig. 7 is only one example for explaining the present invention, and the shape of the unit trains 100a to 100c need not be the same as in Fig. That is, the scope of the present invention is not limited to the shape of the drawings.

The unit trains 100a to 100c include a passenger compartment 101 and an engine compartment 122 connected to the passenger compartment 121. [ The passenger-side cabin room 121 is much larger than the engine room 122.

On the other hand, passengers can not enter and leave the passenger compartment 121 and the engine room 122 of the existing train. However, in this embodiment, when the first and second unit trains 100a and 100b are undocked, the passenger in the first unit train 100a must move to the second unit train 100b, 121 and the engine room 122 are provided with a passenger movable door 123 for moving the passenger.

The passenger movable door 123 may be a sliding door that is automatically turned on / off, but it may be a hinged door.

Docking modules 111 and 112 are provided in all unit trains 100a to 100c. The docking modules 111 and 112 are provided in the unit trains 100a to 100c and are docked or docked with neighboring unit trains 100a to 100c.

In the present embodiment, the docking method between a plurality of unit trains 100a to 100c is applied by a one-row docking method in which docking is performed from the rear.

The docking modules 111, 112 are shown somewhat exaggerated to highlight the docking modules 111, 112.

The docking modules 111 and 112 include a first docking unit 111 provided at the front of the unit trains 100a to 100c and a plurality of unit trains 100a to 100c provided at the rear of the unit trains 100a to 100c, And a second docking unit 112 to which the first docking unit 111 is docked. At this time, the docking modules 111 and 112 may be applied to a relay system.

Meanwhile, in the train speed improvement system according to the present embodiment, for example, a train is operated by a running method, thereby improving the overall train speed.

For example, referring to FIGS. 2 to 6, the first and second unit trains 100a and 100b, which are docked with each other, are docked with each other to enter the second platform 162 from the first platform 161, Assuming that the unit train 100c is stopped on the second platform 162, the first unit train 100a continues to run without being stopped, is docked with the third unit train 100c started in advance, Only the second unit train 100b stops on the second platform 162 so that the passenger can board or descend. As described above, when the first unit train 100a is used as a reference, the speed of the train can be improved because the first unit train 100a is continuously running without stopping. For this control, .

In this embodiment, when the first and second unit trains 100a and 100b, which are docked together and operated together, enter the second platform 162 from the first platform 161, The third unit train 100c stopped at the second platform 162 while the two unit trains 100a and 100b are undocked is started and the first unit train 100a is continuously operated without being stopped And is controlled to be docked with the already started third unit train 100c.

At this time, when the first and second unit trains 100a and 100b are docked, the controller 150 maintains the original speed of the first unit train 100a while the speed of the second unit train 100b is Decelerated and then stopped at the second platform 162. [

In particular, when the first and second unit trains 100a and 100b are undocked, the controller 150 causes the notification unit 140 to move the passenger in the first unit train 100a to the second unit train 100b, And the like. The notification unit 140 may be a voice announcement. That is, since the first unit train 100a does not stop, the passenger in the first unit train 100a must move to the second unit train 100b, and the controller 150 controls the notification.

The controller 150 in charge of this role may include a central processing unit 151, a memory 152, a memory circuit 152, and a support circuit 153.

When the first and second unit trains 100a and 100b which are docked together and operated together in the present embodiment enter the second platform 162 from the first platform 161, The third unit train 100c stopped at the second platform 162 while the second unit trains 100a and 100b are undocked is started and the first unit train 100a is continuously stopped And may be one of various computer processors that can be industrially applied to control the third unit train 100c that has already been started while being docked.

The memory 152 (MEMORY) is connected to the central processing unit 151. The memory 152 may be a computer-readable recording medium and may be located locally or remotely, and may be any of various types of storage devices, such as random access memory (RAM), read-only memory (ROM), floppy disk, hard disk, At least one or more memories.

A support circuit 153 (SUPPORT CIRCUIT) is coupled with the central processing unit 151 to support the typical operation of the processor. Such a support circuit 153 may include a cache, a power supply, a clock circuit, an input / output circuit, a subsystem, and the like.

In this embodiment, when the first and second unit trains 100a and 100b, which are docked together and operated together, enter the second platform 162 from the first platform 161, The third unit train 100c stopped at the second platform 162 while the two unit trains 100a and 100b are undocked is started and the first unit train 100a is continuously operated without being stopped And is controlled to be docked with the already started third unit train 100c.

At this time, when the first and second unit trains 100a and 100b, in which the controllers 150 are docked and operated together, enter the second platform 162 from the first platform 161, The third unit train 100c stopped on the second platform 162 while the trains 100a and 100b are undocked starts to run and the first unit train 100a continues to run without stopping, A series of processes for controlling the third unit train 100c to be docked may be stored in the memory 152. [ Typically, a software routine may be stored in the memory 152. The software routines may also be stored or executed by other central processing units (not shown).

Although processes according to the present invention are described as being performed by software routines, it is also possible that at least some of the processes of the present invention may be performed by hardware. As such, the processes of the present invention may be implemented in software executed on a computer system, or in hardware such as an integrated circuit, or in combination of software and hardware.

Hereinafter, a train speed improvement method according to the present embodiment will be described.

First, the first unit train 100a and the second unit train 100b are docked to enter the second platform 162 from the first platform 161 (S11), as shown in FIGS.

The controller 150 controls the operation of the notification unit 140 so that the passengers in the first unit train 100a move to the second unit train 100b as shown in Figure 3 before entering the second platform 162 completely (S12). The traveling passenger is a passenger to get off the second platform 162.

Next, the docked first and second unit trains 100a and 100b are docked as shown in FIG. 4 (S13). At this time, when the first and second unit trains 100a and 100b are undocked, the first unit train 100a maintains the original speed, while the speed of the second unit train 100b is reduced, (162).

Next, as shown in FIG. 5, the third unit train 100c stopped on the second platform 162 starts to start (S14).

Then, as shown in FIG. 6, the first unit train 100a is docked with the third unit train 100c that has already started without being stopped (S15). After that, the second unit train 100b is reduced in speed And stops at the second platform 162.
