摘要： PROBLEM TO BE SOLVED: To solve the problem that there is a possibility where, in case where a non-electrically-insulated track circuit is used when a train is present in a control boundary track circuit, a logic section connected with a transmitter cannot detect a timing at which a logic section connected with a receiver sets an ATC telegram message of the outer track circuit of the control boundary track circuit to be "not yet transmitted" and transmits the ATC telegram message to the control boundary track circuit regardless of the ATC telegram message is transmitted to the outer track circuit.
SOLUTION: Adjacent logic sections in a digital ATC device are connected with each other via a dedicated LAN. A train entering side logic section is connected with the transmitter in the control boundary track circuit. A train exiting side logic section is connected with a receiver. The train entering side logic section transmits the content of a TD telegram message, which is transmitted to the transmitter via the dedicated LAN, to the train exiting side logic section. The train entering side logic section verifies the content of the TD telegram message which the train exiting side logic section received from the receiver.

摘要： PROBLEM TO BE SOLVED: To provide a digital ATC system which does not infringe or change a control frequency zone of a ground device (train detection, crossing control and the like) related to existing train control, and has no usage restriction of a frequency zone of a digital ATC signal carried to an on-vehicle device.

To the digital ATC signal which a train 30 receives during traveling on a track circuit 1T, the information of the digital ATC signal 2a which the next track circuit 3T should receive is added. Therefore, when entering the track circuit 3T, the train 30 can receive the digital ATC signals without problems even if the frequency zone of the digital ATC signal received by the previous track changes.
