The speed control unit 22 controls the speed of the train 1 by controlling the brake device and the like according to the check result of the speed check unit 21.

  The operation when the train control information is transmitted from the ATC ground device 7 to the track circuits 1T to 3T to control the train 1 will be described.

  The branching device 6 is switched from the interlocking device 9 to the track on the track circuit 3T side, the traffic signal 10 provided at the boundary between the track circuit 3T and the track circuit 2T is set as a G display indicating progress, and the track circuit 1T and track circuit 2T are connected. When information indicating that the absolute signal 5 provided at the boundary has been changed to the R indication that is the stop indication is input to the ATC ground device 7, the control information creation unit of the 1T transmission unit 8a, the 2T transmission unit 8b, and the 3T transmission unit 8c 14 creates train control information including route information and presenting information according to the input information.

  When creating this train control information, as shown in the control information explanatory diagram of FIG. 3, the control information creation unit 14 of the 1T transmission unit 8a uses the route information 24 as information indicating continuity with the track circuit 2T. 1 ”, the track number information indicating the route is“ A2 ”, the track circuit ID is“ 1 ”, train control information indicating the progress indication is created as the indication information, and is transmitted to the track circuit 1T via the transmitter 15. . In addition, the control information creation unit 14 of the 2T transmission unit 8b uses, as the route information 24, information indicating continuity with the next track circuit “0”, number information indicating the route “A1”, and track circuit ID “2”. The train control information indicating the progress display is created as the display information and transmitted to the track circuit 2T via the transmitter 15. The control information creation unit 14 of the 3T transmission unit 8c sets the route information 24 as information indicating continuity with the track circuit 2T as “1”, the track number information indicating the route as “A1”, and the track circuit ID as “3”. Then, train control information indicating the progress display is created as the display information, and transmitted to the track circuit 3T via the transmitter 15. Here, “1” in the information indicating continuity with the next track circuit indicates that there is continuity with the next track circuit, and “0” indicates that there is no continuity with the next track circuit. “A1” indicates a localization path in which the path is from the track circuit 3T to the track circuit 2T, and “A2” indicates an inversion path in which the path is from the track circuit 1T to the track circuit 2T.

  In this state, when the train 1 enters the track circuit 1T and receives the train control information transmitted to the track circuit 1T by the receiver 16 of the on-board device 12, the control information determination unit 18 is sent from the receiver 16. The route information and the present information are extracted from the train control information, and when it is detected that “1” is specified in the information indicating the continuity with the next track circuit of the extracted route information, the extracted route information is data. The storage unit 19 temporarily stores the route information and the presenting information to the pattern creation unit 20. The pattern creation unit 20 creates a speed pattern of the train 1 by referring to the route information and current information sent from the control information determination unit 18 and the various control data and route information stored in the data storage unit 19 to check the speed of the train 1. Send to 21. The speed checking unit 21 checks the sent speed pattern against the speed of the train 1. The speed control unit 22 controls the speed of the train 1 traveling on the track circuit 1T by controlling the brake device and the like according to the check result of the speed check unit 21.

  When the train 1 is running on the track circuit 1T, for example, the train control information transmitted to the track circuit 2T due to a dielectric breakdown occurring in the rail insulation 3 provided at the boundary between the track circuit 1T and the track circuit 2T is received. When the train 1 enters the track circuit 2T from the track circuit 1T and receives the train control signal transmitted to the track circuit 2T, the control information determination unit 18 obtains the route information from the train control information received by the receiver 16. When the current information is extracted and it is detected that “0” is designated in the information indicating the continuity of the extracted route information with the next track circuit, the extracted route information is not temporarily stored in the data storage unit 19. The route information and the presenting information are sent to the pattern creating unit 20. The pattern creating unit 20 collates the number information included in the route information of the track circuit 2T and the number information included in the route information of the track circuit 1T temporarily stored in the data storage unit 19 and sends the number line of the track circuit 2T. When it is detected that the information is “A1” and the track number information of the track circuit 1T does not coincide with “A2”, the course information and the present information of the track circuit 2T are discarded and the train 1 is stopped by emergency brake control.

  On the other hand, when the train 1 enters the track circuit 3T and receives the train control information transmitted to the track circuit 3T, the control information determination unit 18 uses the train control information received by the receiver 16 to display route information and present information. Since the information is extracted and “1” is designated by the information indicating the continuity with the next track circuit of the extracted route information, the extracted route information is temporarily stored in the data storage unit 19 and the route information and the indication are displayed. Information is sent to the pattern creating unit 20 to control the speed of the train 1 according to the progress indication specified by the indication information. When the train 1 enters the track circuit 2T from the track circuit 3T and receives a train control signal transmitted to the track circuit 2T, the control information determination unit 18 determines route information from the train control information received by the receiver 16. And the presenting information are extracted, and if it is detected that “0” is specified in the information indicating the continuity of the extracted route information with the next track circuit, the extracted route information is not temporarily stored in the data storage unit 19. Then, the route information and the presenting information are sent to the pattern creating unit 20. The pattern creating unit 20 collates the sent number information of the track circuit 2T with the track information of the track circuit 2T and the track information of the track information of the track circuit 3T temporarily stored in the data storage unit 19 to check the track number of the track circuit 2T. When it is detected that the information is “A1” and the track number information of the track circuit 3T is coincident with “A1”, the train 1 is made to travel by the progress display which is the display information of the track circuit 2T.

  In this way, when the absolute traffic light 5 is in the R state, a dielectric breakdown occurs in the rail insulation between the track circuit 1T and the track circuit 2T, or the train 1 running on the track circuit 1T overruns the track circuit 2T. The train 1 traveling from the track circuit 1T to the track circuit 2T can be surely stopped even if the vehicle enters the track circuit 2T, and the positioning route and the reverse route can be changed in the track circuit 2T having the branching device 6 without adding equipment or the like. The safety of the traveling train 1 can be improved.
