Zhongxin Chuangwei provides a time synchronization server for Tianfu Airport.

Recently ， Tianfu Airport issued a requirement for a time server. Beijing Zhongxin Chuang Company responded proactively by preparing a detailed proposal for the customer and recommended its own independently developed and manufactured product. The DNTS‑6 time server, as the product submitted for this tender, underwent a fiercely competitive bidding process. Relying on its high‑quality products and comprehensive after‑sales service, Zhongxin Chuang emerged victorious over its competitors. The manufacturer’s products stand out. And Out, ultimately winning the Tianfu Airport Time Server Project.

Tianfu Airport ， Located in Sichuan Province, China Chengdu City Jianyang City Lujia Town Airport Avenue (belongs to Chengdu Eastern New Area Construction scope), located north of Chengdu’s city center 50 kilometers, northwest of Chengdu Shuangliu International Airport Located 50 kilometers northeast of Jianyang city center, it is a 4F‑class international airport, an international aviation hub, one of the highest‑rated airports along the Silk Road Economic Belt, and the primary hub of the Chengdu International Aviation Hub. 。

Tianfu Airport Developed independently by Zhongxin Chuang DNTS-6 Time Server Conduct an in-depth evaluation and arrive at the final results. All are superior to 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-6 It is an intelligent, high-precision device. NTP network time server. DNTS- 6 Network Time Service Server from Standard time information is obtained from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and standard time services are provided 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 thereby synchronize with international standard time. When using GNSS satellite receivers, priority settings can be defined, and configurations supporting single‑receiver/dual‑receiver and single‑antenna/dual‑antenna modes are available; each receiver can be configured individually or in combination to operate in timing mode.

DNTS-6 There is 1-2 one 10/100 adaptive Ethernet ports, with physical isolation between ports to ensure data security; they can all be configured on the same subnet or on different subnets and feature redundancy—failure of one port will not affect the normal operation of the others. Each Ethernet port must be assigned an independent IP address.
