Time Sync for Rail-Transit and Emergency Public Services
Unified time bases and BeiDou positioning-and-timing terminals for high-speed rail, metro, airports, urban rail, emergency command centres and on-board terminals.
Sector Overview
For high-speed rail, metros, airports, urban transit, emergency command centres, and onboard terminals, Yinzhong delivers unified time bases and BeiDou positioning-and-timing terminals.
Rail Timing Needs
- Signalling (CBTC / ATC / ATS) — ms-grade headway ordering
- ISCS — power / comms / fire / PSD unified
- PIS / PA / Display — time-slaved
- AFC — cross-station consistency for clearing
- Operations — dispatch timestamp as legal evidence
Airport Timing Needs
- FIDS unified with PA, PSDs, gates
- ATC high-precision time for tracks and flow
- Security / boarding — passage timestamp traceability
- Baggage handling — key-node timestamps
Yinzhong Stack
Stations / platforms
- YZ-9810 master + LED digital clock network
- Sub-clocks in hall, platform, equipment rooms
- Display slaved to PA / PIS / FIDS
Control centre
- ISCS master integration
- Signalling network timing
- Video surveillance consistency
Onboard / airborne
- BeiDou PNT modules
- Position + time dual output
Multiple time sources across stations, signalling, dispatch centres and on-board terminals drift apart
Emergency command, city-brain and smart-streetlight platforms need a unified, traceable time tag
On-board terminals must hold high-accuracy time and position through GNSS-denied environments such as tunnels and bridges
Legacy timing equipment lacks the vibration, wide-temperature and EMI tolerance required for vehicle-mounted use
Vehicle-Mounted Timing & Positioning
YZ-7202 BeiDou vehicle terminal delivers time sync, positioning and status reporting under vehicle conditions
Unified Station Time
Master + slave clocks unify time displays across stations, terminals, control towers and emergency centres
Multi-Source Resilience
Satellite + long-wave + network multi-source ingest with seamless switchover for tunnels and bridges
Smart-City Backbone
Provides a unified time foundation for smart streetlights, city brains and traffic-signal control
YZ-7202 BeiDou Vehicle Terminal
High-precision BeiDou positioning, timing and status reporting for rail-transit vehicles, emergency vehicles and special-purpose vehicles.
