Sichuan Daying High School is a Provincial Level-I Demonstration Senior High School (Leading Type) in Sichuan Province and a Tsinghua University High-Quality Student Source School.
Founded in 1939, the school was renamed Sichuan Daying High School in 1998 following the establishment of Daying County. The campus is located in Penglai Town, Daying County, at the golden midpoint of the Chengdu–Chongqing economic corridor. It occupies more than 280 acres, with a total building area of over 120,000 square meters.
The school serves nearly 7,300 students and employs 468 faculty and staff, including:
4 Senior Professors
8 Special-Grade Teachers
146 Senior Teachers
Since its founding, the school has graduated over 57,000 students, with more than 26,000 admitted to higher-education institutions, including 4,600 to key universities. In recent years, 9 students have been admitted to Tsinghua University and Peking University, reflecting the school’s outstanding academic performance.
As a major examination center hosting high-stakes provincial and national examinations, Sichuan Daying High School required a high-precision, highly reliable, and centrally managed time synchronization system.
Traditional clock systems presented challenges such as:
Inconsistent time across examination rooms
Manual calibration inefficiencies
Potential risks to examination fairness and compliance
To meet standardized examination site requirements, the school sought a professional solution capable of ensuring millisecond-level synchronization across all examination rooms.
High Accuracy
Examination clocks must maintain extremely small time deviations to ensure fairness and compliance.
High Stability
The system must operate reliably under various environmental and network conditions, without interruption during examinations.
Centralized Management
Remote monitoring and management capabilities are required to allow real-time status checks and rapid fault handling.
