Zhongxin Chuangwei provides a precision clock for the Wuyang Expressway in Hubei Province.

Zhongxin Chuangwei provides a precision clock for the Wuyang Expressway in Hubei Province.

Recently, the Hubei Wuyang Expressway issued a request for time‑server equipment. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑6 model as the bid‑winning solution. 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 Beidou timing‑equipment project on the Hubei Wuyang Expressway.

The Wuhan–Yangxin Expressway is one of the key projects in the development of the Yangtze River Midstream Urban Agglomeration and forms part of the Ningde–Wuhan section of the national highway network. In December 2018, with approval from the Provincial Development and Reform Commission, a “equity partnership + BOT + general contracting” model was adopted. Huangshi Dongchu Investment Group, in collaboration with China Energy Construction Group Gezhouba Company, established Hubei Huangshi Wuyang Expressway Development Co., Ltd. (Wuyang Expressway Company) to advance the project’s construction.

Hubei Wuyang Expressway conducted an in-depth evaluation of the DNTS‑6 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the client expressed high satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The network time server DNTS-61E-GB, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone time server based on the NTP/SNTP protocols. The DNTS-61E-GB obtains standard clock signal information from GPS or BeiDou geostationary satellites and transmits this information over the network, enabling devices that require time signals—such as computers and controllers—to synchronize with the standard clock. Standard clock information is transmitted via the TCP/IP network, and the DNTS-61E-GB supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast data packets 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-61E-GB supports the broadcast mode of the SNTP protocol.

The DNTS-61E-GB has one 10/100M adaptive Ethernet port.
