Zhongxin Chuangwei provides time synchronization equipment to China National Coal Xi’an Design & Engineering Co., Ltd.

Recently ， China National Coal Group Xi’an Design Engineering Co., Ltd. has issued a requirement for a time server. , Beijing Zhongxin Chuang Company is actively cooperating For users A detailed plan has been prepared, and the independently developed and manufactured products of Zhongxin Chuang have been recommended. DNTS-6 Time Server and Digital Sub-Clock As the product submitted for this tender, Zhongxin Chuang emerged victorious after a fiercely competitive bidding process, thanks to its high‑quality offerings and comprehensive after‑sales service, outshining competitors’ solutions. And out, Ultimately awarded the time server from China National Coal Group Xi’an Design Engineering Co., Ltd. Project.

China National Coal Xi’an Design Engineering Co., Ltd. was established in 1954, originally known as the Xi’an Design Institute of the Coal Industry. It is a national Class-A comprehensive design institute and currently belongs to… China National Coal Group Corporation 。

China National Coal Xi’an Design & Engineering Co., Ltd. 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 also 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.

Use simultaneously Priority can be configured on GNSS satellite receivers, supporting single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations. Each receiver can be set to time‑synchronization mode either independently or in conjunction with others.

DNTS-6 There is 1-2 one 10/100/1000M 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.
