Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention installs a ground control device for each section in which a train control track is a section obtained by dividing a track on which a train travels by a predetermined length, and the ground control device is used to stay in its own control range. The present invention relates to a train control method and device for calculating a stop limit position of a running train.

[0002]

2. Description of the Related Art Generally, in order to manage the operation of a train, a ground control device is installed in each section in which a section of a track divided by a predetermined length is set as a control range of the train. The ground control device performs information communication with a train existing in its own control range by radio or the like to take in position information of the train and give control information to the train.

The ground control device is usually provided in a station, and can grasp the train position when the train is in its own control range. Further, the ground control device is connected to another ground control device having a control range in an adjacent section by a signal line so that information communication can be performed.

By the way, the ground control device periodically calculates the stop limit position of the train when the train is in its own control range. The calculation cycle is, for example, about 1 second. When there are multiple trains in the control range, the stop limit position is calculated for each train. In order to calculate the stop limit position, train position information and track condition information such as rolling device condition and track condition are required. The ground control device obtains the train position information for calculating the stop limit position and the track condition information such as the rolling device condition and the track condition from the interlock device.

When the ground control device judges that the calculated stop limit position of the train existing in the own control range exceeds the own control range, that is, the control range boundary with the adjacent ground control device, the train advances. The adjacent ground control device with the next section as the control range is asked to transmit the train presence information and track condition information in the next section via the signal line, and the stop limit position of the train in the own control range is calculated. There is.

[0006]

In the prior art, in order to calculate the stop limit position of a train entering the control range of an adjacent ground control device, the on-rail status and the track condition of the train are received from the adjacent ground control device. There is a need to. The amount of information communication between ground controllers increases. For example, several tens of kbps is required.

However, there is a problem in that the capacity of the signal line between the existing ground control devices is small and the train stop limit position cannot be accurately calculated.

An object of the present invention is to reduce the stoppage limit position of a train entering the control range of an adjacent ground control device even if the amount of information communication between the ground control devices is reduced and the capacity of the signal line between the ground control devices is small. An object of the present invention is to provide a train control method and device that can be accurately calculated.

[0009]

The feature of the present invention resides in that the ground control device advances the train when it determines that the calculated stop limit position of the train existing in the own control range exceeds the own control range. The position calculation request for the stop limit position of the train is transmitted to the adjacent ground control device whose control range is the next section, and the stop limit position of the train calculated by the adjacent ground control device is received. Specifically, the position calculation request only requires the train ID and train position information.

According to the present invention, since the amount of information communication for calculating the stop limit position can be reduced, the capacity of the signal line between the ground control devices can be reduced, and eventually the train stops even with the signal line between the existing ground control devices. The limit position can be calculated accurately.

The position information 106 is wirelessly transmitted to the ground side. The position information 106 transmitted from the train 103 is received by the ground-side wireless transmission device 104 and added to the ground control device 101.

When the ground control device 101 inputs the position information 106, it recognizes the current position of the train 103 and calculates a stop limit (stop limit position) 110 for the train 103. The stop limit 110 is a limit point at which the train 103 can travel safely without danger of colliding with another train or derailing.

The ground control device 1 is used to calculate the stop limit 110.
Positions of other trains recognized in 01 and state information of track equipment are used.

As described above, the stop limit position 110 of the train 103 existing in the control range A of the ground control device 101 is calculated by the ground control device 102 having the adjacent section B where the train 103 enters as the control range. Therefore, the amount of data communicated between the ground control devices 101 and 102 is only the train stop limit position calculation request signal or the stop limit position information, and the train position required to calculate the stop limit within the conventional adjacent control range. It can be significantly reduced as compared with a signal or a route opening state signal.
