DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train operation management method in a train depot, and more particularly to a train operation management method for displaying a train number of a train moving in a train depot following the movement of the train. .

[0002]

2. Description of the Related Art The basis of train management is to grasp the location of a train. For this purpose, a train location and a management number (including a train number or a train number) for identifying the train are assigned to the train. It is necessary to follow the movement of the car and display it correctly at the location where the train is located. In practice, a train operation management system has been introduced for managing a group of trains more efficiently by running a large number of trains running in a line section on a diamond street. Such a train operation management system is a total system mainly composed of an information transmission system, a route control system, and an information processing system. The route control system in this system recognizes where the train is and what the train number of the train is, and as a train based on the information of the track circuit that detects the presence or absence of the train according to the progress of the train The rationality of is confirmed.

[0003] The train number tracking method in this train operation management system utilizes the fact that the train moves in response to a change in the present status of the traffic light, and further detects the movement of the train from a change in the state of the track circuit, and detects the location of the train. The train number has been moved to Further, the train number tracking method in this train operation management system is based on the premise that the destination of the train is one for one traffic signal, and the division and the merging (two To link the knitting).

[0004]

On the other hand, in a train depot that manages trains based on the concept of train numbers rather than the concept of train numbers, the alignment of the premises is complicated, and as long as there is a traffic light, the trains are not endless. That the train is moving to
Furthermore, without having diamond data, division, merge, exchange,
Since rearrangements and additions are frequently performed, it is impossible to simply apply the train management method based on the train number tracking method in the conventional train operation management system.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a train operation management method in a train depot which performs train operation management based on a train number assigned to a train, based on an interlocking condition. Identify the control number of the train moving in the depot, detect the position of the train by the train detection signal from each track circuit in the depot, and follow the control number of the identified train to the position of the train. It is characterized by displaying and displaying and managing the train operation. Therefore, in train depots where train operations such as division, merging, replacement, rearrangement, rearrangement, etc. are frequently performed without having timetable data, only track circuits, route locks, and switches that can be used can be used. The train operation can be managed based on the formation number using only the interlocking conditions of the aircraft.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS By identifying a train management number based on a train detection signal indicating the presence or absence of a train from a track circuit in a train depot and an interlocking condition, and displaying the management number at a position accompanying the movement of the train, Operate trains in train depots without timetable data.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a system to which a train operation management method in a train depot according to one embodiment of the present invention is applied. In the figure, a display unit 11 displays a schematic diagram of track wiring in a depot yard on an interlocking panel, and also displays a signal indicator light, a driving direction indicator light, and the like, and furthermore, a display for displaying a train formation number at a train position. Equivalent to a board. Information processing unit 1
Reference numeral 2 performs information processing such as driving arrangement and operation record in a vehicle depot having no schedule data. The train tracking unit 13
Tracks trains without timetable data. That is,
The train tracking unit 13 recognizes a train by train tracking and detects a train position. The information transmission unit 14 mainly has a function of grasping all information on train operation, and has a function of transmitting information to another operation management center after information analysis. The interlocking unit 15 realizes an overall security function in the yard based on interlocking conditions in which a blocker, a switch, a traffic light and the like are arranged in the depot yard, thereby realizing a safe train. This is to ensure operation. The system monitoring unit 16 monitors whether the information processing unit 12, the train tracking unit 13, and the information transmission unit 14 are functioning normally.

Here, the method of using the respective interlocking conditions of the track circuit, the track lock and the switch and the method of tracking the knitting number in this embodiment are arranged as follows.

[0009] The track circuit is used to determine the on-rail state of the train. Also, the train number is moved to the destination of the train, triggered by a change in the state of the track circuit.・ Dropping: Trains are present ・ Lifting: Trains are not present

[0010] The track lock is used to determine whether or not the track is configured, and to determine the moving direction of the train moving when the track is configured.・ Lock: Path configuration (configuration path direction) ・ Unlock: Path not configured

The switch is used to determine the landing point of the course when the course is configured. Typically,
The normal state of the device is called localization, and other states are called inversions. Here, it is assumed that the normally open direction of the switch is the N direction, and only the N direction condition is input without inputting both the other R direction conditions. Determine the R direction.・ N-direction opening: The path is open in the N direction ・ N-direction non-opening: The path is open in the R direction

The change of the interlocking condition and the change of the train number will be described. First, when the start of the movement of the train is detected, the first inner track circuit of the moving destination falls.
That is, it is determined that the train has started moving based on the train detection signal indicating the presence of the train from the first inner track circuit.

For example, as shown in the interlocking diagram shown in FIG. 2, in the depot where the division is performed, the first and second inner track circuits of the traveling route are dropped while the moving start point of the train remains on-rail. , It is determined that only the first inner track circuit has lifted, that is, the trains A1 and A2 have been split by the train detection signal from the first inner track circuit without a train (see FIG. 2B). . In addition, it is determined that the trains A1 and A2 that were on the train have moved all trains based on the train detection signal indicating that the track circuit at the starting point of the train has been lifted and that there is no train from the track circuit at the starting point of the movement (FIG. 2). (C)).

Further, the determination of the moving section and the moving direction of the train will be described with reference to FIG. 3. The moving destination and the moving direction are determined by starting the movement of the train as a trigger. The destination will track the opening direction of the point machine sequentially from the starting point of movement,
Ask for the final destination. Further, the traveling direction of the train is determined based on the route lock to the final destination. In FIG. 3, the point machine 21 is in the normal position and the point machine 22 is in the opposite position. When the point machine 23 is in the normal position, the final destination of the train A1 of this train number is the third track.

Next, the logical expression of the composition number tracking condition in one embodiment of the present invention will be described with reference to FIG.

[0016] The final destination and the moving direction are determined by the start of the movement of the train as a trigger. And it takes time to move the composition number. Therefore, a logical expression is created based on the interlocking condition, and the composition number corresponding to the conditional expression is moved when the logical expression is satisfied. Specifically, in FIG. 4, the composition number transfer condition from line 30 to line 1 and line 2 is represented by the following logical expression. Note that each conditional expression is a conditional expression for the entire formation movement, and in the case of the divided movement, a conditional expression for the divided movement is separately prepared. The mark “*” in the conditional expression indicates that the condition is a trigger condition in which the satisfaction of the conditional expression is checked when the condition is operated.

Movement from line 30 to line 1 = * (AT lifting) AND (BT drop) AND (21TRSR lock) A
ND (21 localization) AND (22 localization) Move from line 30 to line 2 = * (AT lifting) AND
(BT drop) AND (21 TRSR chain lock) AND (21
Localization) AND (22 inversions)

Next, the basic formation number tracking operation in this embodiment will be described with reference to FIG. 5. The train starts moving, and the track circuit at the movement start point is lifted, that is, the track at the movement start point. Based on the train detection signal indicating that there is no train from the circuit, it is determined that all trains on the line have moved, and the train number of the train is moved to the final destination. Specifically, as shown in FIGS. 5A to 5C, the conditions for this movement can be expressed by the following logical expressions.

Movement from line 1 to line 2 = * (AT lifting) AND (BT drop) AND (21TRSR lock) A
ND (21 localization) AND (22 localization)

Next, the formation number tracking operation in the division and merging according to the present embodiment will be described with reference to FIG. 6. The train starts moving, and the traveling route moves while the train movement starting point remains in the on-line state. From the first and second inner track circuits fall state, only the first inner track circuit was lifted, that is, the first inner track circuit was lifted.
Based on the train detection signal indicating no train from the inner track circuit, it is determined that the train has been divided, and the train number on the final destination side among the train numbers existing at the movement start point is moved. Specifically, as shown in FIGS. 6A to 6C, the conditions for this movement can be expressed by the following logical expressions.

Movement from line 1 to line 2 = (AT fall)
AND * (BT lifting) AND (21T fall) AND (2
1TRSR chain lock) AND (21 stereotactic) AND (22 stereotactic)

When the condition for moving the formation number is satisfied and the formation number is moved, if another formation number exists at the final destination, it is determined that the trains have been merged, and the formation of the final movement destination is performed. The train number is moved without changing the train number. That is, as shown in (c) of FIG. 6, when the train number A2 of the train that has moved to the destination of the train is to be moved, if the train number A3 already exists, the trains are merged. Will be determined.

Next, the formation number tracking operation in the rearrangement according to the present embodiment will be described with reference to FIG. 7. The train starts moving and moves despite the judgment that the train that started moving has been divided. If there is only one formation number at the start point, it is determined that the train has been disassembled (divided one formation into two) due to the rearrangement, and the final movement is performed while leaving the formation number at the movement start point. The same composition number is operated first.
The condition of the movement at this time is the same as the case of the division. In other words, when the condition of the division movement is satisfied, if there are two or more knitting numbers at the movement start point, it is divided (separate two linked knittings), and only one knitting number is at the movement start point. Decompose if it exists (divide one knit into two)
And That is, as shown in (c) of FIG. 7, if the train set number A1 of the train that has moved to the destination of the train has been moved and the train set number A1 also exists at the movement start point, the train reshuffle is performed. It will be determined that it has been performed.

As shown in FIGS. 8A to 8C, when the condition for moving the composition number is satisfied and the composition number is moved, the composition number is the same as the composition number moved to the final destination. Is already present, and if two of the same train numbers A1 are arranged side by side, it is determined that the combination of the trains due to the rearrangement has been performed,
The composition number A1 of the final destination is set to one.

The present invention is not limited to the above embodiment, and needless to say, various modifications and substitutions can be made within the scope of the claims.

[0026]

As described above, according to the present invention,
In a train operation management method in a train depot that performs train operation management based on a train number assigned to a train, a management number of a train moving in the train depot is identified based on an interlocking condition, and each train in the train depot is identified. It is characterized in that the position of the train is detected by a train detection signal from the track circuit, and the train management number of the identified train is followed and displayed to manage the operation of the train. Therefore, in train depots where train operations such as division, merging, replacement, rearrangement, rearrangement, etc. are frequently performed without having timetable data, only track circuits, route locks, and switches that can be used can be used. The train operation can be managed based on the formation number using only the interlocking conditions of the aircraft.
