Zhongxin Chuangwei provides NTP clock synchronization equipment to North China University of Technology.


Recently, North China University of Technology issued a requirement for a clock synchronization system. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed solution and recommended its self‑developed and manufactured DNTS‑9 model as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the time‑server project at North China University of Technology.

North China University of Technology ( North China University of Technology NCUT ), abbreviated as “Northern Industrial University,” is located in Beijing, China. It is a multidisciplinary institution of higher education that prioritizes engineering while integrating the humanities and sciences, offering undergraduate, master’s, and doctoral programs, and is Ministry of Education of the People’s Republic of China and People’s Government of Beijing Municipality A key municipal university jointly established in Beijing. 。                                                                 

North China University of Technology Developed independently by Zhongxin Chuang DNTS-9 Time Server After conducting a thorough evaluation, the results consistently exceeded the specified performance criteria, and we were highly satisfied with both our product quality and after-sales service. We proceeded with procurement and have now put the products into operation without issue.

 

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from navigation and positioning satellite systems such as GPS, BeiDou, GLONASS, and Galileo, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. When using GNSS satellite receivers, users can define priority levels and configure single-receiver/dual-receiver or single-antenna/dual-antenna setups; each receiver can be set to operate in standalone or combined timing modes. If both receivers and other available time sources lose signal, the DNTS-9 relies on its built-in temperature-compensated crystal oscillator or rubidium atomic clock to maintain accurate timekeeping and continuously provide time services to external devices.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑9 network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization for all devices on the network.
