Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a train traffic management system equipped with a traffic display panel, and particularly to a train traffic control system that allows train information to be always reliably obtained in a distributed train traffic management system. Relating to tracking devices.

[Prior art]

In the conventionally used centralized train operation management system, management is performed by a single computer, and the information for each train existing in its memory area is stored separately for each train. This is the only train information.

Therefore, as each train moves, it is possible to centrally manage the tracking of each train.
There was no risk of any problems with the operation display, etc.

However, in the distributed train operation management system that has been put into practical use in recent years, the train operation section is divided into multiple sections centered around stations, etc.
Each control section is treated as an independent control section, and computers and other control devices distributed in each section independently track trains in each control section to obtain train information. When a train passes through a boundary between the two, it is necessary to exchange train information regarding the train between the control devices of these adjacent control sections.

However, in such a distributed system, the operation of each control device is completely independent, and the timing of acquiring train information is completely unrelated to each other. In the process of handing over trains, train information about the same train may temporarily exist in both control devices, or train information about the same train may be missing from both control devices. As a result, conventional distributed systems have had the disadvantage that they tend to cause problems in the overall train operation management, such as abnormalities in the display operation of the operation display panel in the central control device.

[Purpose of the invention]

An object of the present invention is to eliminate the drawbacks of the conventional distributed system described above, and to solve the problem that even when a train passes through the boundary between adjacent control sections, train information regarding the train concerned is missing, or information on multiple trains is displayed at the same time. To provide a train tracking device which can always obtain continuous correct train information without being detected.

[Summary of the invention]

In order to achieve this object, the present invention prevents train information from being missing by providing an overlapping portion in adjacent control sections, and thereby solves the problem caused by duplicate detection of derived train information. This problem is solved by setting the overlapping part of the train in a track section where the train travel direction is always limited to a fixed direction.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a train tracking device in a train operation management system according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a system configuration diagram of a distributed operation management system to which a train tracking device according to the present invention is applied. In the figure, 1a to 1c are station control devices, 2a to 2c are interlocking devices, and 3a to 3d are A transmission device, 4 is a transmission line, 5 is a central processing unit, 6 is an operation display board, 7 is a route setting table, 8 is a train, and 9 is a track.

Each of the station control devices 1a to 1c is installed at a necessary location such as a railway station, has its own transmission device 3a to 3c, and is coupled to the loop transmission path 4 via these, and is 1
Information can be exchanged with the central processing unit 5 via the communication device 3d and the transmission device 3d. And these station control devices 1a to 1c
has its own timetable information, and tracks when the train 8 is present in the control section assigned to it on the track 9, and outputs route control output based on the timetable information to the corresponding interlocking devices 2a to 2a. Output to 2c. In addition, in parallel with this, these station control devices 1a to 1c are connected to the respective interlocking devices 2a to 1c.
Track location information (ON/OFF of each track circuit) via 2c
OFF) and signal status information, and transmits these together with train tracking information (train number and position of the train) within the self-controlled section to each transmission device 3a to 3c.
The signal is sent to the loop transmission line 4 via the .

Connected to the central processing unit 5 are an operation display board 6 for displaying the operation status of the entire line (track position, train number, etc.) as man-machine equipment, and a route setting console 7 for control. The train tracking information transmitted above from each station control device 1a to 1c is taken in and displayed on the operation display panel 6 to enable overall operation management.

Therefore, in such a distributed system, the track 9 is divided into control sections corresponding to each of the station control devices 1a to 1c, but each of the station control devices 1a to 1c has a loop transmission path 4.
By receiving the data flowing above, it is possible to grasp the overall condition of the track 9 and know the condition of the adjacent control section. It is possible to exchange train tracking information when the train exits from one control section to an adjacent control section, and to continuously track the train.

However, if this continues as it is, duplication or omission of train tracking information will occur as explained in the above-mentioned conventional example, but in this embodiment, as explained below, the duplication or omission of information is prevented. be able to.

Therefore, first, a section is found between each station on the track 9 where the running direction of the train is always limited to a fixed direction, and each station control device 1a to 1 is located within this section.
The boundaries of the control sections defined by each of c are located so that they are adjacent to each other. In addition, on a railway line with a double-track configuration, for reasons such as train operation, there are always sections in the up and down direction of the train, such as between stations, where the running direction of the train is always limited to a certain direction. Therefore, there is no difficulty in satisfying the above conditions. In FIG. 1, such sections are indicated by Z _ab and Z _bc , the control sections of each station control device 1a to 1c are indicated by ZA, ZB, and ZC, and their boundaries are indicated by B _ab and B _bc .

Next, as shown in Figure 2, within the sections Z _ab and Z _bc in which the running direction of the train is determined to be one direction, the respective control sections ZA, ZB, and ZC are defined, and the respective boundaries Bab and Bbc are defined. new control sections ZA', ZB', ZC' having these superimposed sections L _ab , L _bc , L _ba , L _cb are set, and these newly set control sections ZA' , ZB', and ZC' are the control sections of the station control devices 1a, 1b, and 1c, respectively. Then, if the overlapping sections L _ab and L _bc are set to be longer than a predetermined length, the train 8 can move between these sections L _ab or L bc.
When a train passes through L _bc , it is always detected redundantly by the station control devices 1a and 1b, or 1b and 1c, so that information regarding this train will not be missing.

On the other hand, in parallel with this, the process shown in FIG. 3 is added to the train tracking information acquisition process by the central processing unit 5.

Therefore, now, at time t ₁ , train 8 is in the control section ZA' near A station, and then at time t 2, train 8 is in the control section ZA' near A station, and then at time t ₂ , train 8 is in the control section _ZA
, and then enters the control section ZB' at time _t3 . Then, the train tracking information regarding the train 8 obtained by the station control device 1a at this time is expressed as Ta,
Similarly, if the train tracking information obtained by the station control device 1b is Tb, the train tracking information Ta is calculated when the train 8 enters the control zone ZA' of the station control device 1a, as shown in FIG. From time t ₁ onwards, from time t ₂
It exists on the loop transmission line 4 during the period from passing through the superimposed section L _ab to exiting the control section ZA' at time _t3 .

On the other hand, as shown in FIG. 42, the train tracking information Tb enters the superimposed section L _ab at time t ₂ , then exits the superimposed section L _ab at time t ₃ , and enters the controlled section ZB by the station control device 1b. ′, then this interval
It appears on the loop transmission line 4 until it passes through ZB'.

Therefore, as is clear from FIG. 4 1 and 2, when the train 8 moves from the control zone ZA' to ZB', the same train 8 moves during the period from time t ₂ to t ₃ .
The two types of train tracking information Ta and Tb always appear overlappingly on the loop transmission line 4, and no matter how the timing of information acquisition by the respective station control devices 1a and 1b is, the train tracking information Ta and Tb None of these will ever be missing.

On the other hand, the train tracking information Ta or Tb existing on the loop transmission line 4, or both of them, is transmitted to the transmission device 3.
d to the central processing unit 5 and processed as data representing the operating status of the train 8. Through the process shown in FIG. 3, which is part of this processing process, the train tracking information Ta and Tb are the overlapping interval L _ab
out of these two train tracking information Ta and Tb, only the information Tb located ahead in the running direction in this overlap section L _ab is extracted as the only train tracking information regarding train 8. , other information Ta is erased, and as a result, the tracking information regarding the train 8 in the central processing unit 5 is always continuous at any timing, as shown in FIG. 4. , and it will be obtained as the only one. Note that the process shown in FIG. 3 at this time is such that the superimposed section L _ab is set within the section Z _ab in which the running direction of the train is always limited to one direction, as explained in FIG. Guaranteed by

The above operation is such that train 8 starts from the control section ZB'.
The same is true when moving towards ZC'; in this case, the overlapping section L _bc is set within the one-way traveling section Z _bc , and this ensures the processing in Figure 3, causing overlap. This is accomplished by making it possible to extract unique information from the information provided.

Note that the above operation is for the uplink,
Needless to say, the same applies to the down line.

Therefore, according to this embodiment, no matter how the train 8 operates, the central processing unit 5 can ensure that the train tracking information regarding this train 8 is not lost and can be grasped as unique. is possible,
It is possible to eliminate the possibility of problems occurring in operation management, such as abnormalities occurring in the display on the operation display panel 6.

〔Effect of the invention〕

As explained above, according to the present invention, a distributed system can be created using a simple configuration in which a superimposed section is provided in the control section controlled by each station control device, and this superimposed section is set not only on the track but also on a specific section that exists. Since it is possible to prevent train tracking information from being lost and to reliably extract unique information from duplicated information, this method eliminates the drawbacks of the conventional technology.
Easily and at low cost create a decentralized train operation management system that eliminates operational management problems in the central processing unit, such as abnormal displays on the operation display panel, and can always perform accurate train operation management. can be provided.
