Description

  The present invention relates to a train management system that manages train presence.

  In conventional railroads, the train tracks are divided into several blocks, and each block is managed so that only one train can enter, thereby preventing a train collision. For this reason, each block 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 contrast, recently, a train control system called ATACS (Advanced Train Administration and Communications System) 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 controller is installed on the train, and the ground controller (base unit) is installed on the ground. The ID of the ground element of a predetermined block among the plurality of blocks installed along the track is read, and the position of the ground element specified by the ID and the speed accumulation by the speedometer from that point By calculating the travel distance, the current position of the train is always detected, and the position information is transmitted to the ground control device. Based on this position information, the ground control device transmits the position information of the preceding train and information indicating the stop limit based on the route to the on-board control device.
The on-board controller creates a brake pattern signal based on the received information and performs brake control. The brake pattern signal is a pattern signal indicating speed control characteristics, and when the train approaches the preceding train, the brake is automatically applied to avoid a collision. According to such ATACS, it is possible to reduce costs and improve safety compared to train control using a conventional track circuit, and it is possible to improve transportation efficiency by performing appropriate interval control. .

Conventionally, for example, Patent Document 1 has been proposed as a technique for managing a train line using a wireless distance measuring method.

  In ATACS, a plurality of control areas (bases) are set on a trajectory, base devices as the ground control devices are provided in the respective control areas, and each base device manages the existing lines of each control area. . The control area is further divided into a plurality of blocks, and a ground unit having an ID is installed in a predetermined block among the plurality of blocks.

In such a train management system, if a base unit is turned off due to maintenance or failure, etc., and the train is running during that time, on-line management is performed in the control area of the base unit. It will disappear. For this reason, when the power supply is turned on again and the base device is restored, there is a problem that the position of the train in the control area cannot be grasped.
For this reason, for example, when there is a train that has entered from another control area while the power is off, when the base device recovers, the position of the train that has entered cannot be immediately grasped, and the preceding train is located closer to the train. If there is a risk of collision, there is a risk of collision.

In addition, since the on-line management information until then is reset when the power of the base device is turned off, for example, when there is a train that is turned off due to staying in the control area of the base device that is turned off, There was a problem that it was impossible to grasp the delayed train when returning.
Accordingly, it is an object of the present invention to obtain a train management system that can reliably perform on-line management of all trains in all control areas even when a base device is down in ATACS.

A train management system according to the present invention is a train management apparatus that manages train management information in all sections and a train that is provided for each predetermined section of the track and that transmits one or more trains in the section from the train. based on the identification information managed for each segment, a plurality of ground train control unit that transmits the train identification information managed for respective sections in the on-rail management device, provided before SL for each line of the boundary of each section detects the train identification information of the train passing through the border, the detected train identification information provided and train identification information detection apparatus to be transmitted to the on-rail management device, the on-rail management device, transmitted from the ground train control unit The train management information is updated based on the train identification information, and when the ground control device is out of order, the train management is performed based on the train identification information transmitted from the train identification information detection device. It is characterized in updating the information.

  According to the present invention, since the train identification information detection device is provided at the boundary of each section (base) and the detection information is directly transmitted to the on-line management device, the base device goes down or train communication fails. In the meantime, the trains in each section can be reliably managed during that time, and the positions of all the trains can be immediately grasped when recovered.

Embodiments of the present invention will be described below with reference to the drawings.

The ID4 train is about to enter base C from outside the system. The arrow attached to each train 2 indicates the traveling direction. Although not shown, each of the bases A, B, and C is divided into a plurality of blocks, and a ground unit having an ID in a predetermined block among the plurality of blocks is installed on the ground. Shall.

  FIG. 2 is a configuration diagram of the train 2. As shown in the figure, the train 2 is equipped with an on-board control device 3, a wireless communication device 4, and a train ID transmitter 5 for transmitting the ID of the own train. Although not shown in the drawings, a ground ID detector, a speedometer, a storage device, and the like are mounted.

  In FIG. 1, a train 2 detects the ID of each ground element by a ground element ID detector, and wirelessly transmits the position information calculated based on the ID of the ground element and the train ID to the base unit. The base device transmits the position information of the preceding train of the train to the train based on the ground element ID and the train ID. Based on this, the train creates a brake pattern signal. At the same time, the base device creates on-line management information indicating which block each train in the base is on, and transmits it to the on-line management device 6 provided according to the present embodiment via the transmission path 7. To do. The standing line management device 6 creates the standing line train ID management table 8 from the standing line management information transmitted from each of the base devices A1, B1, and C1, and grasps the positions of all the trains in the system.

  In the train ID management table 8, the train 2 with ID 1 is at the base A, the train 2 with ID 2 and ID 3 is at the base B, the train 2 with ID 5 is at the base C, and the ID 4 that has entered It is described that the train 2 is present.

  In the present embodiment, a train ID detection device 9 is installed on the boundary of each base and on the ground of the staying block. The ID detection device 9 detects a train ID entering or leaving the base, and transmits the ID information to the on-line management device 6 via the transmission paths 10 and 7. The ID detection device 9 includes a transponder or the like, and detects a train ID transmitted from the train ID transmitter 5 of the train 2.
