Congratulations to China General Nuclear Power Group on the procurement of the Zhongxin Chuangshijie clock synchronization equipment project.

 

Congratulations China General Nuclear Power Group Procurement of New-Creation Clock Synchronization Equipment Project

 

    

 

 

    

Recently, China General Nuclear Power Group issued a procurement announcement for time servers. Beijing Zhongxin Chuang Company actively collaborated to prepare a detailed proposal for the client and recommended products independently developed and manufactured by Zhongxin Chuang. As the product submitted for this tender, the DNTS-84-OGB model emerged victorious after a fiercely competitive bidding process. Thanks to its high‑quality performance and comprehensive after‑sales service, Zhongxin Chuang outperformed competitors’ offerings and was ultimately selected for China General Nuclear Power Group’s time‑server project.

China General Nuclear Power Group (abbreviated as CGN; English abbreviation: CGN, formerly the China Guangdong Nuclear Power Group, is headquartered in Shenzhen, Guangdong Province, and is a centrally administered state-owned enterprise controlled by the State-owned Assets Supervision and Administration Commission of the State Council. CGN has grown and strengthened alongside China’s reform and opening-up process and the development of the nuclear power industry.
    China General Nuclear Power Group (CGN) is guided by the mission of “developing clean energy to benefit humanity.” Over more than four decades of growth, it has established a 6+1 industrial framework, with operations spanning nuclear energy, nuclear fuel, new energy, non-power nuclear technologies, digitalization, technology-driven environmental protection, and industrial finance. CGN operates two mainland‑listed platforms and three Hong Kong‑listed platforms.

China General Nuclear Power Group To China–Singapore Innovation Independently developed DNTS-8 Time server Conduct an in-depth evaluation and arrive at the final results. All Exceeds the parameter requirements And Regarding our company’s product quality and after-sales service Also quite satisfied. Procured successfully and put into use.

 

       

 

 

  Developed by Beijing Zhongxinchuang Technology Co., Ltd. The DNTS-84-OGB time server is a high‑tech, intelligent, stand‑alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high‑precision timekeeping. It can obtain standard time‑signal information from GPS or BeiDou geostationary satellites, as well as from CDMA networks, and transmit this information across the network. Devices requiring time synchronization—such as computers and controllers—can thereby align themselves with the standard time signal. Additionally, when using GPS, BeiDou, and CDMA receivers, users can define priority levels; by default, BeiDou is prioritized, with GPS serving as a backup, and CDMA as an alternative. Finally ; When all three receivers are without signal, The DNTS-84-OGB uses a built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. DNTS-8 4 -0GB uses standard clock information transmitted over a TCP/IP network. The DNTS‑84‑0GB supports multiple popular time‑distribution protocols, such as NTP and time/UDP, and also accommodates custom‑defined time‑broadcast packets on configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. Additionally, the DNTS‑84‑0GB supports the broadcast mode of the SNTP protocol.
