Founded in 1912, Changsha No.1 High School is the earliest provincial public high school in Hunan Province and is directly affiliated with the Hunan Provincial Department of Education. The school is a nationally recognized model institution, holding multiple honors including:
National Model Senior High School
National Youth Science & Technology Innovation Talent Training Experimental School
National Modern Educational Technology Experimental School
National Civilized Campus
National Defense Education Demonstration School
National Psychological Health Education Featured School
As one of China’s most prestigious secondary schools, Changsha No.1 High School undertakes large-scale national and provincial examinations every year, including the National College Entrance Examination (Gaokao).
With increasingly stringent supervision of national examinations, the school needed to fully comply with the “National Standards for Standardized Examination Centers” issued by the Ministry of Education.
The legacy timing system in exam rooms suffered from signal latency, inconvenient calibration, and inconsistent time displays, posing potential risks during high-stakes examinations such as Gaokao and academic proficiency tests.
To ensure absolute time consistency, exam fairness, and operational efficiency, the school initiated a comprehensive upgrade to a high-precision, campus-wide time synchronization system.
We designed and deployed a customized solution tailored to standardized examination environments.
✅ Multi-Source Time Synchronization
BeiDou satellite, GPS, and network (NTP) triple time sources
Automatic redundancy switching
Long-term accuracy: ≤ 0.1 seconds per year
✅ Intelligent Digital Clock Terminals
LED translucent display panels with high visibility
24/7 continuous operation
Built-in power-off memory to preserve accurate time after outages
✅ Centralized Management Platform
Real-time monitoring of 2,000+ terminals
Automatic alerts for abnormal status or deviations
Remote management via web and mobile interfaces
Zero Time Deviation:
During the 2024 National College Entrance Examination, all 89 standardized examination rooms across the campus achieved perfect time synchronization.
Enhanced Supervision Efficiency:
Proctors and administrators were able to verify time consistency in real time using a mobile app.
Improved Examination Integrity:
Examination irregularities decreased by 67% year-on-year, while random inspections by disciplinary authorities achieved a 100% compliance rate.
Ensured strict compliance with national examination standards
Strengthened exam fairness through unified, authoritative time control
