Changjun Xiangfu Middle School, established in 1956, is a modern, standardized, garden-style full secondary school located in the core area of Changsha-Zhuzhou-Xiangtan, managed by the Changsha Municipal Education Bureau. The campus spans 110 acres with over 290 faculty members and more than 3,800 students. With over 60 years of educational heritage, the school continues to cultivate talents rooted in the Huxiang culture.
Facing increasingly stringent requirements for standardized educational examinations, Changjun Xiangfu Middle School sought to ensure uniform exam timing and enhance exam organization efficiency. The existing traditional clock system suffered from large manual calibration errors and unstable signals, failing to meet the strict demands of critical exams such as the National College Entrance Examination (Gaokao) and other provincial assessments.
Comprehensive Coverage: Installed across all teaching buildings, exam rooms, and administrative offices to ensure campus-wide synchronized time.
Multi-Mode Timing Technology: Supports BeiDou/GPS satellite signals, 4G network, WiFi, and Ethernet as time sources with automatic redundant switching. This guarantees stable operation even under extreme conditions like network outages or weak signals.
Visual Time Management: Features red and white LED digital tube displays with adjustable brightness. The clocks show full date and time formats including year, month, day, weekday, hours, minutes, and seconds for clear readability.
Intelligent Operation & Maintenance: Built-in power outage memory allows clocks to resume accurate timing after power restoration. Power-over-Ethernet (PoE) design simplifies wiring and suits various installation environments.
Enhanced Time Accuracy: Exam room clocks achieve zero deviation relative to the National Time Service Center, fully meeting the time synchronization requirements of Gaokao’s electronic monitoring systems.
Improved Management Efficiency: Centralized management platform enables remote control of all clocks, reducing manual calibration needs and lowering maintenance costs by 60%.
Guarantee of Exam Fairness: During the 2024 Gaokao and multiple mock exams, the system delivered zero timing errors, effectively eliminating exam disputes related to clock inconsistencies.
