Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation management system used for railways including monorails, new transportation systems, and maglev railways.

[0002]

2. Description of the Related Art As is well known, a railway vehicle (hereinafter abbreviated as a train) has a much longer braking distance than an automobile or the like, so that a railway vehicle crashes into a preceding train or enters an obstacle that has occurred on the course. There is a high possibility that an accident will occur. In order to prevent such accidents and realize safe and smooth train operation, a train operation management system for managing the operation of a plurality of trains and traffic signals has been introduced.

In a conventional train operation management system, the position of a train is detected by using a track circuit provided alongside a track. The track circuit focuses on a point where the axle of the train short-circuits between two rails, and is provided for each section divided in advance, and detects whether the short-circuit occurs in any of these sections. Thus, the section where the train is located is detected.

[0004] On the basis of the detection results of such track circuits, in a conventional train operation management system, for example, a collision accident with a preceding train or the occurrence of an accident on a route while maintaining the interval between trains at a predetermined distance or more is maintained. To prevent accidents caused by accidents.

However, as described above, the track circuit can detect the position of the train only in sections.
For this reason, in an area such as an urban area where the number of trains operated is large and the train interval is short to control the operation, it is necessary to increase the installation density of track circuits.

On the other hand, in areas with low population density away from cities, trains run at relatively high speed because the stations are long, so it is necessary to install track circuits at a certain density to prevent accidents. However, it is necessary to install many track circuits because of the long operation distance.

As described above, in the conventional train operation management system, it is necessary to install a large number of track circuits not only in an urban area but also in an area with a low population density, so that much cost is required for installation and maintenance. There was a problem.

[0008] The track circuit used in the conventional train operation management system is for detecting a train operating on two rails. For this reason, conventional train operation management systems that use track circuits cannot support new transportation systems that use monorails and tires, or transportation systems that are magnetically levitated and do not touch the ground, such as linear motor cars. Was.

Furthermore, in the conventional train operation management system, train operation commands and signal switching control are performed via a railway or a communication network provided alongside the railway.
There is a problem that maintenance and maintenance of such a communication network require a large cost.

On the other hand, in the conventional system, radio communication is used in combination, but radio communication is not an effective means in mountainous areas due to the topographical problem. Since such an area is often located far from the control device of the system, there is a problem that laying a terrestrial communication network requires too much cost compared to traffic.

[0011]

In the conventional train operation management system, in order to accurately detect the position of a train, it is necessary to lay a large number of track circuits not only in urban areas but also in areas with low population density. There is a problem that much cost is required for installation and maintenance.

[0012] In the conventional train operation management system,
Since the position of the train is detected using the track circuit, it cannot be used for new transportation systems using monorails and tires, or transportation systems that are magnetically levitated and not grounded, such as linear motor cars. There was a problem.

It is a flowchart for demonstrating the process which determines the instruction | indication with respect to the ground traffic signal 100 and the train 600 of 0.

First, in the train operation control device 700, in step 6a, the information collection control means 750a causes the information collection control means 750a to transmit each of the information transmitted from the level crossing device 200, the anemometer 300, the falling rock detection device 400, and the tunnel monitoring device 500 via the geostationary satellite 800.

0 operation command and a switching command of the ground signal 100) are transmitted to the corresponding train 600 and the ground signal 100, respectively.

On the other hand, the train 600 operates in accordance with a command from the train operation control device 700, and the ground signal 100 similarly emits a signal in accordance with the command from the train operation control device 700.

In particular, in the position information of the train, G
We are performing positioning using PS satellites. It is known that some errors occur in positioning using GPS satellites. However, in the case of a railway, since a train operates on a known track, a highly accurate train position detection is possible by matching the detected position with the known track in the processing of the operation command determining means 750b. .

It can be applied to a transportation system without any traffic, and can perform high-precision train position detection at low cost even in a long area between stations.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the train 6
Although the detection of the position information of 00 is performed using the GPS satellites, the position of the train 600 may be detected in combination with the existing track circuit.

According to this, since the reliability of the position information detected by using the GPS satellite can be confirmed, even if the position detection by the GPS satellite cannot be performed for some reason or an erroneous detection is performed, the information is not changed. Can respond.

Further, in the above embodiment, the case where the command for the train 600 and the command for the ground signal 100 are issued has been described, but the present invention is not limited to this. For example, a command may be issued to a branching device that controls point switching at a branching point. It goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0069]
