Description

  The present invention relates to a train management system and method for managing each train when a plurality of trains are merged and divided.

In conventional railroads, a train is divided into several sections and managed so that only one train enters each section, thereby preventing a train collision. For this reason, each section is provided with a track circuit that detects the presence or absence of a train by short-circuiting the rails by the train axle.
In such a train management system using a track circuit, when one train is merged with one or more other trains to form a new train (hereinafter referred to as a merge train), this merge train It was technically difficult to manage the operation. It is also difficult to manage each train when the merged train or one train is divided into a plurality of trains. Conventionally, for example, Patent Document 1 has been proposed for a system for managing a vehicle moving in a vehicle base.

On the other hand, recently, a train control system called Advanced Train Administration and Communications System (ATACS) is being researched and developed. In ATACS, the train itself detects the position of the train, which was conventionally performed by the track circuit. The on-board control device is installed on the train and the ground control device is installed on the ground. Detects the current position of the train by reading the ID of the ground unit installed on the track, and transmits the position information to the ground control device. The ground control device manages each train based on the position information sent from each train, and also provides the on-board control device of each train with the position information of the preceding train of each train and the information indicating the stop limit based on the route. Send. The on-board controller creates a brake pattern signal based on the received information and performs brake control. As shown in FIG. 7, the brake pattern signal is a pattern signal indicating the speed control characteristic with the travel distance l (or time) on the horizontal axis and the speed v on the vertical axis, and automatically when the train approaches the preceding train. The brake can be applied to avoid collision. According to such ATACS, cost can be reduced and safety can be improved compared to conventional train control using a track circuit, and transportation efficiency can be improved by performing appropriate interval control. .

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing in principle a train management system and method according to an embodiment of the present invention. This embodiment manages the merged train and the divided train when the trains are merged and divided in the above-described train control system using ATACS.
In FIG. 1 (a), a train 1 of trains is waiting on a track 5 branched from the track 4. This train 1 has a train ID: 1 as ID information. On the other hand, another train 2 travels in the direction of the arrow on the track 5, and this train 2 enters the track 5 from the track 4 and merges with the train 1. This train 2 has a train ID: 2 as ID information. In this state, the ground control device 6 as the train management device communicates with the train 1 and the train 2 individually, manages the train 1 based on the train ID: 1, and trains 2 based on the train ID: 2. Is managing. Note that the block (section) including the line 5 is managed by the ground control device 6 as a block having an attribute that can be merged and divided in ATACS. When performing merge / split control, first determine whether the current train 1 and train 2 are in the merge / split allowed block, confirm that they are in that block, and then perform the merge / split control. ing.

  Each of the train 1 and the train 2 includes one on-board control device, detects the position of the own train by reading the ground element ID, and transmits this position information to the ground control device 6. The ground control device 6 divides the track on which each train travels into a plurality of blocks each having an attribute and manages the data on the data. Based on the position information from each train, the ground control device 6 transmits, for example, the position information and stop limit information of the preceding train to each train according to the attribute information of the block in which the train is currently located. Each train creates, for example, a brake pattern signal based on these information and controls its own train.

  FIG. 1 (b) shows a state in which the train 1 and the train 2 are merged on the track 5 to become one train 10. At this time, communication between the ground control device 6 and the onboard control device of the train 2 is stopped, and only communication between the ground control device 6 and the onboard control device of the train 1 is performed. Further, the ID of this merged train 10 is train ID: 1 (2) obtained by adding train ID: 2 to train ID: 1. Thereafter, the ground control device 6 manages the merged train 10 based on the train ID: 1 (2). In the merge train 10, train 1 is a main train and train 2 is a slave train. This master-slave relationship may be either the train 1 or 2, but generally the train on the origin side is the master. The operation switch in the cab of each train 1 and 2 can be switched to forward, backward, or middle after merging, but mainly based on the state of each operation switch or a predetermined train You may do it.

  FIG. 2 shows a state where three trains of train 1, train 2 and train 3 are merged into one merged train 20. The ID of train 3 is train ID: 3. In this case, the main train is the train 1, the trains 2 and 3 are slave trains, the communication between the ground control device 6 and the on-board control devices of the train 2 and the train 3 is stopped, and the ground control device 6 and the train Only communication with one on-vehicle controller is performed. The ID of the merged train 20 is train ID: 1 (2) (3) obtained by adding train ID: 2 and train ID: 3 to train ID: 1.

FIG. 3 shows a message format of information transmitted from the on-board controller of each train before the merge to the ground controller, and information transmitted from the on-board controller of the main train to the ground controller after the merge.
In FIG. 1-3 show the message | telegram information transmitted from the on-board controller of each train before merger. No. 20-31 shows the message | telegram information transmitted from the onboard control apparatus of the main train after merger. No. From 27 to 31, the number of merged trains and the ID information of the slave train are transmitted. Thus, after the merger, the master train always transmits the ID of the slave train to the ground control device. Thereby, since the ground control apparatus 6 manages the merged train and also manages the slave train formed in this merged train, each train after the merged train is divided into a plurality of trains can be continuously managed. .

  FIG. 4 shows a state where the merged train 10 of FIG. 1 (b) is divided into a train 1 and a train 2. In this case, train 1 and train 2 are the main trains. In addition, the ID of train 1 is train ID: 1, and the ID of train 2 is train ID: 2. The ground control device 6 communicates with each on-board control device of the train 1 and the train 2. Similarly, when the merged train 20 in FIG. 2 is divided into train 1, train 2, and train 3, each train becomes a main train, and each train has a train ID: 1, train ID: 2, train ID: 2. Will have.

FIG. 5 shows a method of transmitting information between the trains 1, 2, and 3 in the case of the merged train 20 of FIG.
In FIG. 5, each of the trains 1, 2, 3 is provided with an on-board control device 7, an information transmission device 8, a wireless device 9, an on-board child 11, a speedometer 12 and a cab 13. Each information transmission device 8 of each train is connected in series so that information can be transmitted between the trains.

  When controlling this merged train 20, each train 1, 2, 3 always keeps track of the connection relationship between each train in the merged train, the train length and the top position of each train, so that each train is always You can calculate and grasp the position of your train. For this purpose, the on-board control device 7 of the trains 1, 2, and 3 transmits and receives the above connection relationship and the train length of each train through the information transmission device 8. In addition, the on-board controller 7 of the train 1 calculates the leading position of the merged train 20 and controls the merged train 20 such as brake control. At the same time, the on-board controller 7 of the train 1 distributes the head position of the merged train 20 to the trains 2 and 3 by the information transmission device 8, and the on-board controller 7 of the trains 2 and 3 And the head position of the own train is calculated based on the connection relationship between the train length and the train length of the own train.

  In this way, the trains 1, 2, and 3 in the merged train 20 always know the position of the own train, so that the merged train 20 is divided and control is continued when control in a new train is started. It can be performed. That is, in the ATACS, when starting the control of each train, it is necessary to first know the position of each train. For that purpose, the vehicle element needs to detect the ground element and read its ID. According to the present embodiment, since necessary information is transmitted between the trains using the information transmission device 8, control can be started immediately after the division without waiting for the detection of the ground element.

  FIG. 6 shows an example of the connection relationship in the merged train 20, and the train 1 recognizes that the 0 train is connected to the front and the 2 trains are connected to the traveling direction. In addition, train 2 recognizes that one train is connected forward and one train is connected to the traveling direction, and train 1 is connected two trains forward and zero after the train. Recognize.

According to the present embodiment described above, when a plurality of trains are merged into a single train, this is obtained by adding ID information of another train to the ID information of one train in this merged train. Since it is managed as ID information of the merged train, it is possible to manage each train before the merge in ATACS and easily manage the merged train after the merge.
In addition, when the merged train is divided into a plurality of trains, the ID information of each divided train is managed as the ID information of the train, so the merge train is managed in ATACS, and each train after the division Can be easily managed.

Moreover, since each train in the merged train always calculates the position of its own train by communicating information with each other, ATACS can immediately start managing each train without detecting the ground element after the division.
Further, when merging / dividing trains, first, it is determined whether or not each train is in the merging / dividing permission block, so that it can be distinguished from merging due to unexpected contact such as collision.
