Train control system and handover method in train control system

摘要

A ground control apparatus is provided with: a train speed calculation unit that calculates train speed by using train present track position information notified from a train; a predicted passage time calculation unit that calculates a predicted passage time at a previously-stored H/O point based on the H/O point, the calculated train speed, and brake performance; a wireless CH reservation unit that performs processing of reserving a wireless CH of a H/O target wireless base station based on usage of a wireless channel allocated to the H/O target wireless base station and the calculated predicted passage time; and a wireless CH reservation result notification unit that notifies a reservation result of the wireless CH reservation unit to a H/O source wireless base station.
