Regional master clock

1. The master clock and slave clocks are equipped with a master-slave distributed control structure and an integrated mechanical and electrical design.

The entire system utilizes closed-loop control.GPS/Beidou Dual-Mode Automatic Time Synchronization System→Microcomputer Monitoring System←→Master Clock Control System←→Core Drive Management System←→Subclock Real-time Feedback System←→Remote mobile operating systems and related components.

Highly integrated system package, featuring a control mainboardSMT surface mount technology process, with improved electromagnetic compatibility and enhanced stability, is currently the tower clock control system used domestically.

2. Smart Timekeeping Control SystemMicrocomputer control, fully automatic operationThe master-slave clock system employs a closed-loop control to maintain synchronization with Beijing Time. It achieves this through the coordinated operation of the master clock and an intelligent movement controller: the controller automatically scans the pointer positions, tracks the master clock's operation, sends timing signals to the corresponding stepper motors, and receives real-time feedback signals to promptly correct any timing deviations caused by external factors, ensuring the accuracy and reliability of the movement's operation.

3. GPS/BeiDou Satellite Automatic Calibration SystemThe system control center is connected to satellite receiving signal equipment, allowing for around-the-clock, real-time reception of satellite standard time signals. It compares and aligns standard time with master clock time, outputs a full-time standard time code for synchronization, and automatically synchronizes the master and slave clocks. It calibrates every second to eliminate cumulative errors and ensure precise timekeeping.
