1. The master clock and slave clocks utilize a master-slave distributed control structure, featuring an integrated mechanical and electrical design.

The entire 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 control, fully automatic operationThe master and slave clock system utilizes a closed-loop control to maintain synchronization with Beijing Time. This is achieved through the coordinated efforts of the master clock and an intelligent movement controller: the controller automatically scans the pointer positions, tracks the master clock's operation, and promptly corrects timing deviations caused by external factors, ensuring the movement's accuracy and reliability.

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 synchronizing the master and slave clocks, eliminating cumulative errors, and ensuring precise timing.
