Recently, Henan Energy Group issued a procurement request for NTP time servers. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal 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 Henan Energy Group’s time server project.

Hebi Coal Chemical Company of Henan Energy and Chemical Group has completed four projects: a 600,000‑ton‑per‑year methanol plant, a 100,000‑ton‑per‑year 1,4‑butanediol plant, a 60,000‑ton‑per‑year poly(tetramethylene ether) glycol plant, and a 3,000‑ton‑per‑year succinic anhydride plant, with a total investment approaching RMB 10 billion.

Henan Energy & Chemical conducted an in-depth evaluation of the DNTS‑9 series time server independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the company expressed strong satisfaction with both our product quality and after-sales service, proceeding to place a successful order and put the system into operation.

 

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 clients.

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 across all devices on the network.

◆Device information can be displayed:
