Qingdao No.37 Middle School

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

The system employs a closed-loop control.GPS/BeiDou dual-mode automatic time synchronization system→Microcomputer Monitoring System←→Mother Clock Control System←→Core Drive Management System←→Subclock Real-Time Feedback System←→Remote mobile operating systems and parts.

2. Smart Timekeeping Control SystemMicrocomputer control, fully automatic operationThe master-slave clock system employs closed-loop control to maintain synchronization with Beijing Time. It operates through the coordinated efforts of the master clock and an intelligent core controller: the controller automatically scans the pointer positions, tracks the master clock's operation, and promptly corrects timing deviations caused by external factors to ensure the core'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 synchronizes the master and slave clocks, eliminates cumulative errors, and ensures precise timing.
