DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train control device, and more particularly to a train control device employing an in-car signal system.

[0002]

2. Description of the Related Art Conventionally, a train control system employing an in-car signal system employs a track circuit system in which a rail on which a train travels is divided into fixed sections and the divided rail is part of an electric circuit. ing. That is, the track circuit type in-vehicle signaling system is configured such that signal indication information is transmitted from the ground equipment to the separated rails.

A train running on the above-mentioned rail is provided with a vehicle child (antenna) for receiving signal display information from the rail, and a signal display always received via the vehicle child. An on-board device for processing information is provided. The on-board device continuously presents (displays) the received signal display information in the vehicle (cab) to notify a staff (driver) of the information, and based on the received signal display information, A
It is configured such that TS (automatic train control device) control and ATC (automatic train control device) control are performed.

[0004] In the train control apparatus of the above-mentioned construction, the ground signal can be removed, so that equipment costs can be reduced and maintenance and management costs can be reduced. Regardless of the surrounding conditions of the driving section, the signal indication can always be confirmed, and for example, the signal indication can be confirmed even in dense fog. Since it is possible to easily confirm the change of the signal display, the security is higher than the terrestrial signal system in which a traffic signal is installed on the ground, and the transport efficiency can be improved. There is a feature that there is no possibility of erroneous recognition of a signal because the signal indication in the inside of the block section occupied by the train (in the direction in which the train travels) is not seen.

However, in the above-mentioned conventional in-vehicle signal type train control device, since the driver cannot recognize the boundary of the block section in advance, it is necessary to provide a warning sign, and As in the case of the signaling method, it is not possible to recognize in advance the operating conditions of the inner block section, so that it is necessary to provide a notice signal. Furthermore, since track circuits are continuously installed and the number of track circuits increases, there is a drawback that equipment costs increase and maintenance management costs increase.

The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide an in-car signal type train control device capable of reducing the overall cost. .

[0007]

In order to achieve the above object, a train control device according to the present invention is a train control device comprising an on-board device and a ground device, wherein the on-board device is an on-board device. When it is detected that a train equipped with has entered a predetermined wireless communication area, performs a display in the vehicle based on the signal display information transmitted by radio from the ground device, the ground device, A predetermined length of the track on which the train travels is defined as a predetermined wireless communication area, and predetermined signal indication information is transmitted by wireless communication to the train in the predetermined wireless communication area. . In addition, the travel control of the train from the predetermined wireless communication area to the next predetermined wireless communication area is performed by measuring distance information from the previously input predetermined wireless communication area to the next predetermined wireless communication area and measuring. It is performed based on the travel distance information of the train. And
The ground equipment is characterized by being connected by radio communication with an adjacent ground equipment. Further, the wireless communication between the on-board device and the ground device is performed by adding predetermined identification information.
