The BKS series time synchronization system is independently developed by Yantai Clock and Watch Research Institute Co., Ltd., including large-area time systems, urban rail transit network center clock systems, high-speed railway passenger dedicated line time synchronization systems, small-area wireless clock systems, multi-level distributed time synchronization systems and other products. This series of products is suitable for subways, light rails, high-speed railways, stations, airports, ports, nuclear power plants, schools, hospitals, intelligent office buildings, high-end residential areas and other places. It adopts automatic time calibration of external standard time signals such as GPS/Beidou, Internet of Things technology, network remote monitoring, key module redundancy settings, touch screen and keyboard dual control and other technologies to synchronize the time of the equipment and provide a time benchmark for other automation equipment in the area.

Main technical features:

◎Intelligent, using Internet of Things technology, network remote monitoring, touch screen and keyboard dual control, intelligent control. Fault isolation, software and hardware redundancy and other technical measures make the system reliable.

◎Multiple standard time sources can receive standard time signals such as GPS and Beidou, and receive upper network time signals of various interface types as needed, as the standard time source of the time synchronization system, and can realize automatic switching of time sources;

◎Modular design, the main working modules realize dual hot backup, and can be hot-swapped with power on; key modules are easy to set up, expand, operate and maintain redundantly.

◎Interface standardization and diversification, using universal standard interfaces: NTP network time interface, IRIG-B code time interface, ASCII code serial communication interface, AFNOR interface, etc.;

◎High-precision time base, the base time source uses high-precision constant temperature crystal oscillator, high-precision rubidium atomic clock, etc., and the time accuracy level can reach 10-9-10-12.

◎The system adopts a distributed structure and network communication mode, and there is no need to increase the center capacity. In the later period, when the line is extended or the area such as buildings is expanded, the central master clock does not need to add any hardware or any changes, and the network management software only needs to add monitoring of new sites. Save expansion costs for users.
