Unified Precision Time System is intended for precise time synchronization with all systems that require time synchronization and time displaying for the staff and passengers.
The system synchronizes the central time server (Central Master Clock) time with Coordinated Universal Time and then all slave clocks are synchronized with the central time server of the system.
Unified precision time system consists of:
- one central time server (Central Master Clock) situated in OCC;
- Slave Master Clocks situated on the all stations;
- Digital/Analogue Slave Clocks, situated on the stations, in the OCC, depots, service-and-office building, etc.
Implementation of the Unified precision time system will allow to synchronize operation of all systems, provide simultaneous performing of the control commands for different systems from OCC as well as to carry out logging of all systems operation in universal time.
