|1. (WO2017195315) ON-BOARD DEVICE AND GROUND SYSTEM|
|Applicants:||KYOSAN ELECTRIC MFG. CO., LTD.
|Title:||ON-BOARD DEVICE AND GROUND SYSTEM|
The purpose of the present invention is to properly ascertain the track range where a train can be present even with another train coupled thereto, and achieve safe travel control of the train, and more particularly to achieve safe travel control in relief operations performed by a relief train. In an on-board control unit 21 of an on-board device 20, a coupling detection unit 216 detects the coupling of a disabled train 2 to a train. If coupling is detected by the coupling detection unit 216, a train occupancy range calculation unit 213 updates train length information 227 using the number of cars of the disabled train 2, and then calculates train occupancy range information using the updated train length information 227. Furthermore, if coupling of the disabled train 2 to the train is detected by the coupling detection unit 216, a travel control unit 214 controls the running and stopping of the train with the disabled train 2 coupled thereto.
