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

The complete system employs a closed-loop control, including a GPS/BeiDou dual-mode automatic timing system, microcomputer monitoring system, master clock control system, movement drive management system, subordinate clock real-time feedback system, and remote mobile operation system, among others.

2. Intelligent Timekeeping Control System: Microcomputer controlled, fully automatic operation. The master-slave clock system employs closed-loop control to maintain synchronization with Beijing Time. The coordinated work of the master clock and the intelligent movement controller accomplishes this: the controller automatically scans the pointer position, tracks the master clock's operation, and promptly corrects timing deviations caused by external factors to ensure the accuracy and reliability of the movement.

3. GPS/Beidou Satellite Auto-Calibration System: Connects to the system control center and satellite signal receiving equipment, providing all-weather, real-time reception of satellite standard time signals. It automatically synchronizes the master and slave clock times, eliminating cumulative errors, and ensuring precise timekeeping.
