Description

Description: [Industrial field of application] The present invention relates to a train operation management method capable of safely carrying out repair work and inspection work of railway lines.

[Prior Art] Conventionally, repair work and inspection work of track circuits, communication equipment, electric power equipment, etc. along a railway line have been carried out between the operation of commercial trains and after the last train.

However, because it depends on the monitoring of the actual work on the safety site side, an accident may occur if a train other than the planned timetable is operated. Therefore, in order to prevent an accident, the ground signal equipment is controlled for safety and the train is stopped for a long time in a wide section.

[Problems to be Solved by the Invention] As described above, the conventional train operation management method secures safety by monitoring the site side, and since the ground signal equipment is manually controlled, the safety is high. There is a problem in that it is not sufficient and the train operation is seriously hindered.

The present invention has been made to solve the above problems, and an object thereof is to obtain a train operation management method capable of automatically ensuring the safety of workers and minimizing the obstacles of train operation. To do.

[Means for Solving the Problems] A train operation management method according to the present invention is a track circuit installed along a running track of a train to detect the presence of a train in each section, and a safety facility connected to the track circuit. Including the ground signal equipment for ensuring the safety of trains, station control equipment installed in each station to control security equipment, and connected to the station control equipment, track circuit and via the station control equipment The central control device for exchanging information with the ground signal equipment is provided, and the station control device collates train schedule information and planned track closure information preset in the central control device, and When the schedule information conflicts with the track closure information, the train is stopped by driving and controlling the ground signal equipment.

[Operation] In the present invention, the central control unit automatically and reliably controls the ground signal equipment based on the line blockage information based on the repair and inspection work plan.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a block diagram showing a train operation management device to which an embodiment of the present invention is applied. (1) is a train, (2) is a track circuit composed of a plurality of sections for detecting the on-rail position of the train (1), (3) is a signal transmission line connected to each section of the track circuit (2).

(4) is a ground signal equipment connected to the track circuit (2) through the signal transmission path (3), and includes security equipment such as traffic lights. (5) is a plurality of station control devices installed in each station to control the security equipment, and connected with an input / output device (not shown) such as a CRT display, an indicator lamp, a console including a switch and a keyboard. Has been done.

(6) is an information transmission line connected to each station control device (5),
(7) is a station controller (5) via the information transmission path (6)
The central control unit (8) is connected to the central control unit (8), and is an input / output unit including a console for exchanging information with the central control unit (7).

Next, an embodiment of the present invention will be described with reference to the explanatory views of FIG. 1 and FIG.

First, the central control unit (7) is connected via the input / output unit (8).
The train schedule information (1a) to (1d) shown in Fig. 2
At the same time, the planned track closure information (10) based on the repair and inspection work as shown by the shaded area is set while confirming the time and position information on the display device that displays the train timetable information. The timetable information (1a) to (1d) and the line blockage information (10) are transmitted to each station control device (5) via the information transmission path (6) in correspondence with its management section.

The station control device (5) collates scheduled timetable information (including operating time and position information) for each train with the roadway blockage information, and if both sides match without conflict, the route configuration information is transmitted to the ground signal. It is input to the equipment (4) and the operation of the train (1) is permitted through the signal transmission path (3) for each section of the track circuit (2).

Also, for example, as shown in the line block information (10) corresponding to the shaded area in FIG. 1, at 12:20 in the section between B station and C station.
When repair / inspection work is performed from 1 minute to 12:50, the line blockage time zone changes for each section, so the timetable information of the preceding train (1b) and the timetable information of the following train ( 1c) does not conflict with the track closure information (10). Therefore, trains in the section between B station and C station, including trains scheduled to operate according to the timetable information (1b) and (1c),
Everything operates as planned, there is no stoppage and there is no problem.

On the other hand, as shown in the broken line in the repair / inspection work plan, when the section range and time zone of the line blockage information are set wide, the station controller (5) sets the line blockage set by the central controller (7). Trains that check information and timetable information (1b) and (1c) and conflict with track closure information, that is, timetable information (1b)
The train according to (1c) and (1c) is stopped by driving and controlling the ground signaling equipment (4) before entering the closed track section.

At this time, like a train running on the timetable information (1b),
Conflict time with line blockage information, that is, stop time (12:20 to 12: 5
It is desirable to stop at station B when 0) is long, and when the conflict time with the track closure information, that is, the stop time (12:40 to 12:50) is short, as in the case of a train that operates on timetable information (1c). It is desirable to approach and stop just before the line block section. However, in this case, both trains may be stopped at the B station, and the conflicting section or conflicting time may be reliably avoided.

If the construction time is extended during the repair / inspection work, new line blockage information is immediately set in the central control unit (7) via the input / output unit (8).

Similarly, since the operation of the train (1) for each section is automatically controlled based on the line blockage information set in the central control unit (7), even if the monitoring on the site side is insufficient. The repair and inspection work can be performed safely.

In addition, the station control device (5) and the central control device (7) can surely manage the line closed section, so that the obstacle to the train operation can be suppressed to the minimum.

[Advantages of the Invention] As described above, according to the present invention, a train circuit that is installed along a running track of a train and detects the presence of the train in each section, and a security facility connected to the track circuit are provided. Ground signal equipment to ensure the safety of the station, station control equipment installed for each station to control the security equipment, and connected to the station control equipment, track circuit and ground signal equipment via the station control equipment. With a central control unit for exchanging information between
The station control device collates the train timetable information preset by the central control device with the planned track closure information, and if the train schedule information conflicts with the track closure information, drives and controls the ground signal equipment. Since the train is stopped by doing so, there is an effect that a highly efficient train operation management method capable of suppressing obstacles in train operation and safely performing track maintenance work can be obtained.
