Abstract

A method operates an automatic train control system which has an electronic signal box, a balize and a frequency track circuit. To configure the train control system so as to be constructed from components of the European train control system and of the frequency track circuit without substantial additional development effort, the balize is acted upon by indicator messages of a first type of the electronic signal box via an actuation module for modular elements having an addressable memory for the number of currently free block route segments. Indicator messages of a third type are created from indicator messages of a second type. A functional relationship between the addresses of the memory and code information of the frequency track circuit is taken into account during the creation of the third indicator messages. A transmitter of the frequency track circuit is acted upon as a result of the third indicator messages.

First claim

The invention claimed is:

1. A method for operating an automatic train control system containing an electronic interlocking connected to a balise and a frequency track circuit, which comprises the steps of:
actuating the balise via an operating module for modular elements by means of pointer telegrams of a first kind, namely first pointer telegrams, of the electronic interlocking, the operating module having an addressable memory for a number of currently clear block sections;
creating pointer telegrams of a third kind, namely third pointer telegrams, from pointer telegrams of a second kind, namely second pointer telegrams, of the electronic interlocking, wherein a functional relationship between addresses of the addressable memory and code information of the frequency track circuit is taken in to account for creating the third pointer telegrams; and
actuating at least one transmitter of the frequency track circuit via a relay arrangement in response to the third pointer telegrams.

2. The method according to claim 1 , which further comprises:
providing a Chinese train control system (CTCS) level 2 pointer telegrams as the first pointer telegrams; and
providing a European train control system level 2 pointer telegrams as the second pointer telegrams;
providing a CTCS balise as the balise; and
using a bijective function for creating the third pointer telegrams.

3. The method according to claim 1 , which further comprises converting the first pointer telegrams into communications telegrams in a telegram converter.

4. The method according to claim 1 , which further comprises feeding the third pointer telegrams to a digital input/output device in which operating signals for the relay arrangement are generated.

5. An automatic train control system, comprising:
an electronic interlocking generating pointer telegrams of a first kind, namely first pointer telegrams, and pointer telegrams of a second kind, namely second pointer telegrams;
a balise connected to said electronic interlocking;
a frequency track circuit connected to said electronic interlocking and having at least one transmitter;
an operating module for modular elements connected to said electronic interlocking, said operating module having an addressable memory for a number of clear block sections and having said balise as one of said modular elements;
a pointer telegram creator connected to said electronic interlocking, said pointer telegram creator creating the pointer telegrams of a third kind, namely third pointer telegrams taking a functional relationship between addresses of said addressable memory and code information of said frequency track circuit into account;
a relay arrangement connected to said at least one transmitter of said frequency track circuit; and
a digital input/output device connected to said pointer telegram creator, said digital input/output device generating operating signals for said relay arrangement disposed downstream of said digital input/output device.

6. The train control system according to claim 5 , wherein in a case of the first pointer telegrams as Chinese train control system level 2 (CTCS-L2) pointer telegrams and the second pointer telegrams as European train control system level 2 (ETCS-L1) pointer telegrams, said pointer telegram creator is implemented such that the third pointer telegrams are created from the second pointer telegrams according to a bijective function, and said balise is a CTCS balise.

7. The train control system according to claim 5 , further comprising a telegram converter, said operating module is connected to said electronic interlocking via said telegram converter.

8. The train control system according to claim 5 , wherein the first pointer telegrams are Chinese train control system level 2 pointer telegrams and the second pointer telegrams are European train control system level 2 pointer telegrams.
