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

The system employs a 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.

2. Smart Timekeeping Control SystemMicrocomputer controlled, fully automatic operationThe master-slave clock system employs a closed-loop control to maintain synchronization with Beijing Time. It is achieved through the coordinated operation of the master clock and the intelligent movement controller: the controller automatically scans the pointer position, tracks the master clock's operation, and promptly corrects any timing deviations caused by external factors to ensure the accuracy and reliability of the movement.

3. GPS/BeiDou Satellite Automatic Calibration SystemConnected to a system control center and satellite receiving signal equipment, it receives satellite standard time signals around the clock and in real-time, automatically synchronizes the master and slave clocks, eliminates cumulative errors, ensuring precise timekeeping.
