As one of theimportant parts of rail transit, the time synchronization system mainlyprovides unified standard time information for subway passengers and staff, andprovides standard time to other systems. The setting of time synchronizationsystem plays an important role in ensuring the accurate timing of rail transitoperation and improving the quality of operation service.
The timesynchronization system consists of Beibeidou/GPS satellite receiver,first-level master time synchronization, second-level master timesynchronization, slave time synchronization, transmission channel and networkmanagement.
The systemscheme adopts two-level networking, and the time synchronization type is422\NTP\PTP.
