Title:
GROUND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/195317
Kind Code:
A1
Abstract:
The present invention provides a novel ground device for achieving coordinated opening-closing control of a platform door and a vehicle door. A ground control system 30 performs polling with ground devices 50 serving as a primary station and a train 2 serving as a secondary station. A ground device 50b, which is a ground device 50 of the ground device system 30, carries out polling at a first communication frequency and obtains train position information from the train 2. When the train 2 reaches a close-to-arrival range, including the stopping position in a station, the ground device 50b changes the communication frequency from the first communication frequency to a higher frequency second transmission frequency. Then the coordinated opening-closing control instruction information received from the platform door control device 60 is transmitted to the train 2 by polling, and the vehicle-side state information obtained from the train 2 by polling is transmitted to the platform door control device 60.
