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.

The complete system integrates highly, with a control mainboard utilizingSMT surface mount technology process, offering enhanced electromagnetic compatibility and stronger 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 control, fully automatic operationThe master-slave clock system employs closed-loop control to maintain synchronization with Beijing Time. It accomplishes this 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, sends timing signals to the corresponding stepper motors, and receives real-time feedback signals to promptly correct timing deviations caused by external factors, ensuring the accuracy and reliability of the movement's operation.

3. GPS/Beidou Satellite Automatic Calibration SystemThe system connects to a central control center and a satellite signal receiving device, enabling real-time, around-the-clock reception of satellite standard time signals. It compares and corrects standard time with master clock time, outputs a full-time standard timecode for synchronization, and automatically synchronizes master and slave clocks, recalibrating every second to eliminate cumulative errors and ensure time accuracy.
