TRAIN SECURITY SYSTEM

Japanese Patent JP2017193234

A

PROBLEM TO BE SOLVED: To provide a train security system to set an optimum lock amount in consideration of an occupancy ratio and a travelling state of a vehicle in calculating an approach lock section distance and a lock time from an actual speed of the vehicle using a ground device and an on-vehicle device.SOLUTION: A train security system includes a vehicle 1 that travels on a rail track 9 and is equipped with an on-vehicle device 15 for controlling the travelling, and a ground device 16 for communicating with the on-vehicle device 15 and controlling a travelling track. A wheel 5 of the vehicle 1 includes a tachometer generator 6, and the on-vehicle device 15 includes a storage part 2, an on-vehicle arithmetic part 3, an on-vehicle transmission/reception part 4, an on-vehicle transmission/reception antenna 7 for a ground element, and an on-vehicle transmission/reception antenna 8 for radio communication. The ground device 16 includes a switch 11, a signal device 10, the ground element 13, a ground transmission/reception antenna 12, and an interlocking device 14. The on-vehicle arithmetic part 3 calculates a brake distance of the vehicle and a switch lock time using geographical information and occupancy ratio statistical information acquired from the storage part 2, and a current speed of the vehicle 1 acquired from the tachometer generator 6, and outputs them to the interlocking device 14.SELECTED DRAWING: Figure 1
