Zhongxin Chuangwei provides clock synchronization equipment for the Xue Family Courtyard.

Zhongxin Chuangwei provides clock synchronization equipment for the Xue Family Courtyard.

Recently, the Xuejia Courtyard issued a request for a time server. Beijing Zhongxin Chuang promptly collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑7 time server as the bid‑winning product. 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 Xuejia Courtyard’s time‑synchronization server project.

The Xue Family Courtyard was built in the mid-Qing Dynasty, facing south and oriented north–south. It is a three‑courtyard, four‑sided compound covering an area of 1,011.60 square meters. The extant buildings, arranged along the central axis, include, in sequence: the southern wing, the entry hall, the hall’s upper story, and the northern building.

Xuejia Courtyard conducted an in-depth evaluation of the DNTS-7 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and they expressed high satisfaction with both our product quality and after-sales service, ultimately proceeding with a successful purchase and deployment.

The DNTS-7 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-7 obtains standard time information from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and provides standard time services 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 synchronize with international standard time.

When using GNSS satellite receivers simultaneously, priority can be configured; the system supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations, with each receiver capable of operating in standalone or combined timing modes.

The DNTS-7 features 1 to 4 adaptive 10/100/1000 Mbps Ethernet ports, with physical isolation between ports to ensure data security. All ports can be configured on the same subnet or on different subnets, providing redundancy—failure of one port will not affect the normal operation of the others. Each Ethernet port must be assigned an independent IP address.
