Unified Time and Frequency Solutions for the Intelligent Transportation Industry
This solution proposes a unified time and frequency solution for intelligent transportation, taking T830 clock server as the core and constructing a three-layer architecture of "core-transmission-access". It realizes sub-microsecond to millisecond level grading precision timing through multi-reference source intelligent source selection algorithm and PTP/NTP dual engine. The solution supports multiple scenarios such as urban traffic management, intelligent high-speed, rail transportation, vehicle-road coordination, etc., is compatible with the stock network, evolves smoothly, and provides unified monitoring and operation and maintenance means to build a highly reliable, engineered and unified time reference for the intelligent transportation system.
