Congratulations to Shaanxi Changqing Energy & Chemical on the procurement of newly developed time synchronization equipment.

Recently, Shaanxi Changqing Energy and Chemicals Published Time server The procurement announcement, with Beijing Zhongxin Chuang Company actively cooperating. For users A detailed plan has been prepared, and products independently developed and manufactured by Zhongxin Chuang have been recommended. DNTS-7 series Type As the product submitted for this tender, Zhongxin Chuang stood out by defeating competitors’ offerings thanks to its high‑quality products and comprehensive after‑sales service, ultimately… Awarded to Shaanxi Changqing Energy & Chemical Co., Ltd. Time server Project 。

Shaanxi Changqing Energy & Chemical Co., Ltd. was established in On January 18, 2010, a large-scale modern coal‑chemical enterprise was jointly established through investment by Xuzhou Mining Group Co., Ltd., Shaanxi Coalfield Geological Group Co., Ltd., Nanjing Chengzhi Clean Energy Co., Ltd., and Shanghai Baosteel Gas Co., Ltd., with a registered capital of RMB 1.5 billion.

The company is primarily engaged in the development and construction of coal-to-methanol projects and their downstream product lines. Annual production capacity… The first phase of the 1.5-million-ton methanol project, a 600,000-ton-per-year methanol facility, required an investment of approximately RMB 4 billion and entered commercial operation in May 2013. The second phase, a 900,000-ton-per-year methanol plant, is currently under construction with an estimated investment of about RMB 6 billion.

Shaanxi Changqing Energy and Chemicals To China–Singapore Innovation Independently developed DNTS-7 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. ！

The network time server developed by Beijing Zhongxinchuang Technology Co., Ltd. DNTS-7 is a high‑tech, intelligent, stand‑alone time server based on the NTP/SNTP protocols. It obtains standard clock signals from GPS geostationary satellites and disseminates this information across the network, enabling devices that require precise timing—such as computers and controllers—to synchronize with the standard clock. Standard clock data is transmitted over TCP/IP networks, and DNTS-7 supports multiple popular time‑distribution protocols, including NTP and time/UDP, as well as custom‑defined time‑broadcast 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, DNTS‑7 supports the broadcast mode of the SNTP protocol.
