Client: Sun Yat-sen University (SYSU) – Guangzhou, Zhuhai & Shenzhen Campuses
Industry: Higher Education / Smart Campus & Exam Administration
Solution Provided: BeiDou/NTP Time Server, Standardized Exam Room Clocks, IoT Synchronization & Management Platform
Sun Yat-sen University (SYSU), founded in 1924 by Dr. Sun Yat-sen, is one of China’s top national universities, well known as a birthplace of early revolutionary education and modern research culture. Today, SYSU operates as a comprehensive, research-oriented, and internationally recognized institution with campuses in Guangzhou, Zhuhai, and Shenzhen.
As a Ministry of Education “Double First-Class” university hosting more than 50+ national-level examinations annually, SYSU faced significant challenges in maintaining consistent and reliable time synchronization across its multi-campus network.
| Issue | Impact |
|---|---|
| Time deviation in exam halls | ±2 minutes difference risked fairness & national exam compliance |
| Multi-campus collaboration delays | Remote teaching, research labs & conferences lacked unified timing |
| Time “islands” in smart campus systems | Surveillance, e-class boards, and recording systems not synchronized |
These problems created risks in exam security, academic coordination, digital management, and compliance.
To address these challenges, SYSU partnered with SHUTAI (a brand of Changsha Tianqiong Electronic Technology Co., Ltd.) to build a unified time architecture based on BeiDou satellite time + NTP precision network synchronization.
BeiDou + 5G dual redundancy timing
Accuracy up to ≤10 nanoseconds
Complies with Education Informatization 2.0 timing security standards
Supports 5000+ network terminals including HIS, campus network, IoT, and video systems
Anti-glare LED display with HH:MM:SS precision
BeiDou/GPS/Telecom/NTP multi-source calibration
Date + Weekday display & power-off memory protection
Optional PoE version for fast deployment
Unified control across multi-campus networks
Monitoring, alerts, automatic drift correction
Real-time device status & exam mode configuration
Low-interference crystal oscillator design
Laboratory timing jitter control ＜1μs for precision instruments
| Benefit | Improvement |
|---|---|
| Exam Hall Synchronization | Time deviation reduced to ＜0.5 seconds |
| Exam Security & Fairness | 3,000+ exam rooms, zero complaints during 2023 college entrance exams |
| Cross-Campus Collaboration | Scheduling & teaching coordination efficiency +40% |
| Smart Campus Data Integration | Surveillance / e-learning / access system timestamps fully unified |
| Maintenance & Cost Efficiency | LoRa/NTP deployment reduces annual operating cost by 30%+ |
“The SHUTAI synchronization system eliminated timing discrepancies across all campuses and fully met standardized examination requirements. It is now core infrastructure for our smart campus operations.”
