Product Description
The T620 NTP Time Server supports the NTP and SNTP network synchronization protocols and is a high-precision, large-capacity, and highly secure clock product. The device hardware is designed with redundancy architecture, and the high-precision clock is directly sourced from the atomic clocks of various satellites in the GNSS system. It tames the local clock source through signal analysis to achieve precise maintenance of the local clock after satellite signal loss.
The device software utilizes multiple anti-interference detection and identification algorithms developed by Beidou Bontai to detect signal anomalies caused by interference and malicious attacks on GPS signals. With its unique embedded hardware design and efficient Linux operating system, it can flexibly expand various clock signal outputs.
It fully supports the latest NTP time synchronization protocols, MD5 secure encryption protocols, and certificate encryption protocols, achieving network time accuracy at the microsecond level. It also supports TOD, 10MHz, 1PPS, log recording, USB port for upgrade and download, and dry contact alarm functions. Together with Beidou Bontai's independently developed unified network time monitoring software, it easily realizes network time synchronization and effective monitoring.
The T620 NTP Network Time Server can be widely used in various fields, including government, defense, finance, securities, insurance, mobile communications, cloud computing, e-commerce, energy and power, oil and petrochemicals, industrial automation, intelligent transportation, security, smart cities, and the Internet of Things.
System Architecture
The T620 NTP Network Time Server innovatively integrates seamless switching technology for reference sources, high-precision Time Interval Counter (TIC) technology, and adaptive precision frequency measurement and control technology. It adopts a modular design and consists of a Beidou receiver, GPS receiver, high-performance industrial-grade motherboard, human-machine interface and monitoring management unit, local clock disciplining unit, output interface module, and power module.
The core of the T620 NTP Network Time Server is composed of a 64-bit high-performance CPU, high-speed FPGA, and high-stability oscillator (rubidium atomic clock or OCXO). It utilizes Linux for real-time multitasking parallel processing and scheduling.
