Zhongxin Chuangwei provides precise clock synchronization for Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology.


Zhongxin Chuangwei provides precise clock synchronization for Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology.

 

Recently, Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology, issued a request for a time server. Beijing Zhongxin Chuang Company 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 highly competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the time‑synchronization server project at Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology.

Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology, is located at No. 1095 Jiefang Avenue, Wuhan, Hubei Province (Main Campus); No. 501 Gaoxin Avenue, East Lake New Technology Development Zone, Wuhan, Hubei Province (Guanggu Campus); and No. 288 Xintian Avenue, Caidian District, Wuhan, Hubei Province (China–France New City Campus). Founded in 1900, it is a tertiary hospital integrating medical care, education, and scientific research.

Tongji Hospital, affiliated with Tongji Medical College of Huazhong University of Science and Technology, 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 the hospital expressed high satisfaction with both the product’s quality and our after-sales service, leading to a successful procurement 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 being set to time‑synchronization mode either independently or in conjunction with others.

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, and the system supports redundancy—failure of one port will not affect the operation of the others. Each Ethernet port must be assigned an independent IP address.
