2. Description of the Related Art FIG. 3 is a schematic block diagram of a conventional dual-system train control communication device. 10 is provided, and when the train a travels on the track T, the ground element 11 is provided at a position on the ground side where the car child 10 can face.

[0005]

This train control communication device is, for example, an ATS.
When used in the -P train control system, the distance information sent from the code processor (not shown) is transmitted from the ground element 11 via the relay 12. Therefore,
When the train a approaches the ground child 11 and the train child 10 reaches the communication area of the ground child 11, the signal received via the train child 10 is used to ensure train operation as much as possible. It is configured to be processed by the transmitter / receivers 13a and 13b formed in a dual system.

[0006]

In the transmitter / receivers 13a and 13b, the traveling pattern is generated based on the received distance information in consideration of the braking (breaking) characteristics of the train a, and the traveling pattern is passed beyond the stop target point. The train a is monitored and controlled so as not to do so.

[0007]

Although the above-mentioned ground element 11 has been shown as an example of being supplied with radio waves from the ground side, it receives electric power waves supplied from the upper side of the vehicle to obtain a power source, and the information fixed in advance is thereby obtained. In some cases, a non-powered type that transmits to the upper side of the vehicle is used.

[0008]

[0006]

[0009]

However, the above-mentioned conventional train control communication device has the following problems in order to secure train operation.
Although the transmitter and receiver mounted on the vehicle are formed in a dual system, a means for exchanging data between the ground side and the vehicle upper side,
That is, since the antenna is single, there is a problem that no countermeasure is taken for the failure of this antenna part.

[0010]

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and the purpose thereof is to improve the reliability of train operation by providing a dual antenna system. The purpose is to provide a control communication device.

[0011]

[0008]

[0012]

In order to achieve the above-mentioned object, a train control communication device according to the present invention is provided with a car top provided at a lower portion of a train traveling on a track, and the train has the track. By the ground element provided at the ground position through which the car child passes when traveling, data is transmitted from the ground side to the vehicle upper side or from the vehicle upper side to the ground side, and on the vehicle upper side,
In a train control communication device that processes transmission and reception data in a dual system, the car uppers are provided in a pair with a predetermined space therebetween, and the grounding conductors can face each other at the same time. It is characterized in that a pair is provided while maintaining.

[0013]

[0009]

[0014]

In the above structure, when the train runs on the track and approaches the ground track, all the train tracks face the ground track at the same time to transfer data. Therefore, on the upper side of the car,
The signals sent and received through each train can be processed by each system.
