Train operation control apparatus, operation management apparatus, train control system, and train operation method

An operation management apparatus comprising:

• a storage unit capable of storing position information on a plurality of trains acquired from a ground control apparatus that collects the position information on the plurality of trains;
• and
• a control unit to, when position information on a first train is not acquired from the ground control apparatus for a specified period, instruct a second train that is a train traveling behind the first train to change a mode to a rescuing mode in which train operation is performed at a specified speed, and instruct the first train to change a mode to a rescued mode in which train operation is performed with a train interval between the first train and the second train being adjusted to a specified train interval, wherein
• on the basis of the position information on the first train, the control unit controls a point machine to cause the first train to enter a refuge track, and when the first train stops at a specified movement authority limit on the refuge track, the control unit instructs the first train to change a mode to a refuge mode in which a stop state on the refuge track is continued, and instructs the second train to change a mode to a normal mode that corresponds to a normal operation state.

A train control system comprising:

• an operation management apparatus to, when position information on a first train is not acquired for a specified period from a ground control apparatus that collects position information on a plurality of trains, instruct a second train that is a train traveling behind the first train to change a mode to a rescuing mode in which train operation is performed at a specified speed, and instruct the first train to change a mode to a rescued mode in which train operation is performed with a train interval between the first train and the second train being adjusted to a specified train interval;
• the second train to, while operating in the rescuing mode, measure a train interval between the first train and the second train using a range sensor, calculate a head position of the first train using information on a train length of the first train and information on the measured train interval, transmit information on the head position of the first train to the operation management apparatus, and perform train operation at the specified speed using movement authority limit information acquired from the operation management apparatus;
• and
• the first train to, while operating in the rescued mode, measure a train interval between the first train and the second train using a range sensor, and perform train operation such that the measured train interval becomes equal to a specified train interval.
