Founded in 1956, Gong'an No. 3 High School is a key provincial model high school in Jingzhou, Hubei. With over 3,000 students and faculty members and a campus spanning multiple academic and living zones, the school is recognized for its strong academic culture and the guiding spirit of “Self-improvement, Collaboration, Dedication, and Excellence.”
To support its modernization goals and ensure a unified learning environment, the school initiated a complete upgrade of campus time synchronization infrastructure.
Before the upgrade, outdated and decentralized clocks caused:
| Problem | Impact |
|---|---|
| Time differences across buildings | Class transitions & exams easily disrupted |
| Manual adjustments & inconsistent displays | Increased staff workload and operational inefficiency |
| No unified monitoring or fault detection | Higher maintenance cost + unreliable performance |
The school needed a secure, centralized, synchronized time system that ensured accuracy, visual consistency, and easy management across all zones.
SHUTAI implemented a customized “One Core – Multi-Terminal” architecture tailored to campus operations.
Built-in high-stability crystal oscillator (10⁻¹²–10⁻⁹ frequency stability)
IEEE 1588 precision synchronization & NTP/Network time broadcast
Millisecond-level accuracy across the entire campus network
| Area | Equipment | Features |
|---|---|---|
| Teaching Buildings / Corridors / Playgrounds | DH2248 LED Digital Clock | 200m visibility, HH:MM:SS format, date & weekday display, auto-calibration; compliant with national exam room standards (2017/2023) |
| Auditorium / Administration | R16W-E Silent Analog Clock | Elegant aesthetic, battery-free design, silent movement suited for academic environments |
| Sports Field / Outdoor Square | 86” Outdoor Smart Display | Real-time exam countdown, class schedule, emergency broadcast & alerts |

After one academic year of operation:
| Outcome | Achievement |
|---|---|
| System accuracy | ＜10 milliseconds synchronization campus-wide |
| Operational reliability | 99.8% device uptime |
| Cost efficiency | Maintenance cost reduced by 45% annually |
| Exam management | Zero timing errors during key exams |
| Staff workload | Remote management reduces manual work significantly |
