Precise Timing, Intelligent Collaboration -- Building Time and Frequency Infrastructure for Next-Generation Intelligent Transportation Systems

Beidou Bontec provides high-precision and high-reliability time synchronization and navigation and positioning solutions for the intelligent transportation field, covering intelligent networked vehicles (V2X), highway intelligent toll collection systems, high-speed railway communication and dispatching platforms and urban intelligent signal control. We build a safe and reliable time and frequency foundation through IEEE 1588v2 Precision Time Protocol (PTP), TSN deterministic network, anti-jamming GNSS positioning and combined navigation technologies. The product supports domestic software and hardware platforms to meet the demand for nanosecond synchronization and stable timekeeping for key applications such as automatic driving edge sensing, high-speed vehicle-road coordination, and unified scheduling of station control centers. Together with BDMonitor network-wide visualization platform, it realizes intelligent and distributed management of transportation infrastructure.

Unified Time and Frequency Solutions for the Intelligent Transportation Industry

Time Synchronization Requirements for Urban Traffic with Multiple Accuracy Levels

Intelligent transportation system has nanosecond, microsecond and millisecond demands, corresponding to V2X, signal control, video forensics and other services. The demand for PTP/NTP/physical timing methods varies significantly among different services, and all scenarios must be covered by the unified benchmark + hierarchical access strategy.

Common pain points in the current network

Urban traffic control, high-speed and rail scenarios generally have problems such as large generation span of equipment, mixed timing systems, missing monitoring, and inconsistent time across security domains, which lead to second or even minute deviations between different systems and make it difficult to support stable operation of key services.
