1. Master and slave clocks employ a master-slave distributed control structure, an integrated mechanical and electrical design:

The entire system utilizes a closed-loop control.GPS/BeiDou dual-mode automatic time synchronization system→Microcomputer Monitoring System←→Master Clock Control System←→Core Drive Management System←→Sub-clock Real-time Feedback System←→Remote mobile operating systems and related components.

The complete system integration is highly sophisticated; the control mainboard utilizesSMT surface mount technology process, offering improved electromagnetic compatibility and enhanced stability, is currently the most advanced in China.Please provide the Chinese content to be translated.The Tower Clock Control System.

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 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 is connected to a control center and satellite receiving signal equipment, which receives satellite standard time signals in real-time, 24/7. It compares and corrects the standard time with master clock time, outputs full-time standard synchronization time codes, and automatically synchronizes the master and slave clocks. It calibrates once every second to eliminate cumulative errors, ensuring precise timing.
