Title:
CLOCK SYNCHRONIZATION COMMUNICATION SYSTEM AND METHOD FOR RAIL TRAIN
Document Type and Number:
WIPO Patent Application WO/2021/063300
Kind Code:
A1
Abstract:
A clock synchronization communication system and method for a rail train, relating to the field of rail train dispatching. The system comprises a signal reception unit, a control center, and a signal distributor. The control center are respectively connected to the signal reception unit and the signal distributor, and the signal distributor is connected to at least one external base station. The signal reception unit receives a clock time synchronization source, and sends the clock time synchronization source to the control center. The control centers extracts a clock synchronization signal from the clock time synchronization source, and sends the clock synchronization signal to the signal distributor. The signal distributor sends the clock synchronization signal to the at least one external base station simultaneously, such that each base station performs clock synchronization by means of the clock synchronization signal.
