DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic train control device for controlling the running speed of a train by receiving train control information transmitted from a ground device to a track circuit by an on-board device of the train, and an automatic train control device. About the method.

[0002]

2. Description of the Related Art A conventional automatic train control device is an automatic train control on-board device (hereinafter referred to as an "on-vehicle device") mounted on a train 22 like an automatic train control system 200 shown in FIG.
Call. ) 21 and an automatic train control ground device (hereinafter, referred to as a rail) installed in each track section of the track circuit 24 as a rail.
Called "ground equipment." ) 23. And
In the conventional automatic train control device, according to the ordinary railway operation rules, the absolute stop signal of the track section where the last vehicle of the preceding train exists and the allowable stop signal of the track section behind this section are different. Mandatory. The absolute stop signal is a signal in which, when the continuation train enters the absolute stop section which is the track section where the last vehicle of the preceding train is present, the continuation train applies an emergency brake to make an emergency stop, and is usually no signal. The permissible stop signal is a signal transmitted from the ground device so that when the continuation train enters the permissible stop section which is a track section one section behind the absolute stop section, the continuation train applies a brake and stops in the permissible stop section. And is usually a signal. Further, in the conventional automatic train control device of the non-insulated track circuit system without electrical boundary equipment such as a resonance circuit at each boundary of each track section, the allowable stop signal is one section behind the absolute stop section. It cannot be transmitted to the track section, and is further transmitted to the track circuit one section behind.
Therefore, the orbital section that is one section behind the absolute stop section must be the absolute stop section, and the allowable stop section that can transmit the allowable stop signal is one section behind the section.

Accordingly, the track sections 24a to 24 shown in FIG.
As shown in e, in the track circuit 24 divided into a predetermined track section length and used as a part of the electric circuit, the track section 24a where the last vehicle of the preceding train 22 'exists is the first absolute stop section, The track section 24b is a second absolute stop section, and the track section 24c is an allowable stop section. That is, when the continuation train 22 enters the permissible stop section 24c, it must receive the service brake signal 01, apply the service brake, and stop in this section, and stop in the second absolute stop section 24b or the first absolute stop. When entering the section 24a, an emergency brake must be applied and an emergency stop must be performed.

[0004] In the on-board device 21 of the automatic train control system 200 shown in FIG.
Receives an allowable speed signal including a service brake signal from each track section of the track circuit 24, transmits the received allowable speed signal to the receiver 21b, and the receiver 21b transmits the allowable speed signal to the speed checker 21d. Send. Further, the speed generator 21c receives an actual traveling speed signal from the wheel, and transmits the received traveling speed signal to the speed checker 21d and the speedometer. When the permissible speed signal indicates the permissible speed, the speed checker 21d compares the actual running speed with the permissible speed, applies a brake so as to run at or below the permissible speed, and reduces the running speed. If the permissible speed signal is a service brake signal, control is performed so that the service brake is applied and the vehicle stops within the permissible stop section. Also,
If the receiving antenna 21a does not receive the allowable speed signal from the track circuit 24 and the speed checker 21d does not receive the allowable speed signal, the speed checker 21d determines that the allowable speed signal is an absolute stop signal and performs emergency braking. It controls so that emergency stop is performed.

[0005]

As described above, in the conventional automatic train control system 200, the track section one section behind the track section in which the last vehicle of the preceding train exists is defined as an absolute stop section, and The track section behind the section had to be set as an allowable stop section. For this reason, the train interval is widened by the length of the absolute stop section and the allowable stop section, resulting in a loss of the train interval. Also, when performing high-density operation, it is necessary to subdivide the track circuit in order to recover this train interval loss and shorten the train interval,
This has led to an increase in the number of track circuits.

SUMMARY OF THE INVENTION It is an object of the present invention to receive information on an allowable stop section transmitted from a ground device to a track section behind one section of an absolute stop section by an on-board device of a train, and allow a part of the absolute stop section to be allowed to stop.

The track section 14a where the last vehicle of the preceding train 12 'exists is a first absolute stop section that is a no-signal section, and the track section 14b that is one section behind the first absolute stop section is a second absolute stop section that is a second signal-free section. This is an absolute stop section, and the track section 14c one section behind the second absolute stop section is an allowable stop section information receiving section in which the continuing train 12 receives the allowable stop section entry signal and the allowable stop section length signal. The permissible stop section entry signal indicates that the continuation train 12

Therefore, it is not necessary to secure the allowable stop section alone,
The track circuit 14 can be effectively used. Further, the train interval can be shortened, and the train delay when train operation is disrupted can be reduced. In addition, since it is not necessary to subdivide the track circuit when the operation interval between trains is reduced due to high-density operation, the number of track circuits can be reduced.
