Zhongxin Chuangwei provides time synchronization equipment to Jinzhou Petrochemical.


Zhongxin Chuangwei provides time synchronization equipment to Jinzhou Petrochemical.

 

Recently, China Jinzhou Petrochemical issued a tender for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its independently developed DNTS‑8 time server along with digital sub‑clocks as the bid‑winning products. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality offerings and comprehensive after‑sales service, ultimately securing the Jinzhou Petrochemical time‑server project.

China National Petroleum Corporation Jinzhou Petrochemical Company is a key refining and petrochemical enterprise under China National Petroleum Corporation. Enterprise . Located in Liaoxi Corridor , facing south Bohai Bay , the city of Jinzhou where it is located is Western Liaoning region the central city, the Beijing–Shenyang, Beijing–Harbin, and Beijing–Datong railways, and Beijing–Shenyang Expressway The city boasts convenient sea, land, and air transportation.

Jinzhou Petrochemicals The company conducted an in-depth evaluation of the DNTS-8 time server, independently developed by Zhongxin Chuang. The results exceeded all specified performance parameters, and the company expressed strong satisfaction with both our product quality and after-sales service, proceeding smoothly with procurement and deployment.

 

 

The DNTS-8 time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high precision. The DNTS-8 time server obtains standard clock signal information from GPS geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. When all receivers lose signal, the DNTS-8 relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-8 uses standard clock information transmitted over TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP; it can also accommodate custom‑defined time‑broadcast packets from Zhongxinchuang Technology, with 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-8 supports the broadcast mode of the SNTP protocol.
