5. Key Features of Kexin Tower Clock1) Time Indication Function: Features hour, minute, and second hands (or two hands) for time indication.2) Smart Drive Features: 1-32 drive platters, platter diameter 1-10 meters.3) Auto-calibration Feature: The mother-child clock system employs a closed-loop control, with the movement providing feedback on its timekeeping, and automatically calibrating.4) Automatic Time Synchronization Feature: In the event of a power outage, the memory unit automatically retains the sub-clock data, and automatically syncs back to standard time upon power restoration within 6 months.5) Smart Lighting Function: Automatic on/off of lighting equipment.6) Power Failure Compensation Function: The smart core continues to operate normally within 12-24 hours after a power outage, ensuring the clock does not stop during power outages. Automatically adjusts to standard time within 6 months after power is restored.7) Safety Protection Features: The entire system is powered by a 12V DC safe voltage, providing users with effective safety protection.8) Maintenance-Free Feature: The entire tower clock system is designed for longevity with a reasonable structure, requiring no manual maintenance.9) GPS Satellite Time Synchronization Function: Real-time reception of time signals from GPS satellites, outputting full-time standard synchronized time codes (including date and time), and automatically synchronizing master clock time to eliminate cumulative errors and ensure time accuracy.10) Synchronization Time Feature: The master clock system can provide standard synchronization time signals to other systems.11) Microcomputer Monitoring Function: The computer utilizes an Intel 64-bit dual-core processor in conjunction with self-developed monitoring hardware and software systems, enabling comprehensive remote control of the master-slave clock system. It also allows for monitoring and adjustment of functions such as timekeeping and chime.12) Smart Alarm Function: Automatically plays high-fidelity CD-quality music for time announcements, using the standard British Big Ben chime. Customizable time announcement content is available. The alarm amplifier can be automatically scheduled to turn on and off.13) Multi-media Time Announcement Function: Utilizing our independently developed multi-media time announcement software, featuring powerful functions and flexible operation, the music library is rich in content. Users can change the time announcement settings at any time, announcing any music or voice at any desired time, such as: at 6 AM playing the "The East is Red" music, at 7 AM playing the "Big Ben" music; on May 1st International Labor Day, playing "We Workers Have Strength"; on October 1st National Day, playing "The March of the Volunteers"; during the Spring Festival, playing festive music or advertising phrases like "XX Group extends New Year's greetings to the people of the city, wishing them...".
