Primary and Seconadry Clock, Synchronous Time Server, Standard Time Synchronization System

1,The Compas synchronous clock system is a system that uses GPS and Beidou satellites to
accurately control the time source and achieve synchronous operation of multiple clock devices.
Widely used in public places that require high temporal consistency, such as subways, airports,
hospitals, and schools.
2,The synchronous clock system has the characteristics of high precision, strong
stability, and easy maintenance. It can ensure that all devices display the same
time, avoiding various problems and inconveniences caused by time errors.
3,A synchronous clock system typically consists of a master clock, NTP standard time server, time
code allocator, and various forms of sub clocks. The main clock provides a standard time signal,
the sub clock receives and displays the time, and the time allocation network is responsible for
transmitting and managing the time signal.

WORKING PRINCIPLE
1. The central master clock receives standard time signals from GPS, Beidou, 4G, and other sources;
2. Transmit standard time signals to various sub clock devices through signal splitting output interface devices
and transmission lines;
3. Simultaneously providing unified standard time signals to other software systems through signal splitting
output interface devices;
4. Provide standard time signals to the local area network through NTP servers or monitoring computer 10/100M
network cards;
5. Synchronize the time of other communication systems within the entire network with the time of the
synchronous clock system, thereby achieving a unified time standard for all systems within the entire project;
6. The system standard configuration can include 512 analog and digital sub clocks, with a maximum
communication distance of 1200 meters. Repeaters can be added if the distance exceeds 1200 meters;
Communication adopts RJ45 interface and AC 220V power supply; NTP server interfaces with other systems
based on Ethernet TCP/IP interface protocol.
