Zhongxin Chuangwei provides NTP clock synchronization equipment to the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine.

Zhongxin Chuangwei provides NTP clock synchronization equipment to the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine.

Recently, the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine issued a request for a clock synchronization system. Beijing Zhongxin Chuang Company responded proactively by developing a detailed solution and recommending its self‑developed and manufactured DNTS‑9 model 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 time‑server project at the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine.

The Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine (Jiangxi Provincial Hospital of Traditional Chinese Medicine and Jiangxi Provincial Orthopedic Hospital) is a Grade III, Level A TCM hospital. It serves as the leading and central institution for TCM medical care, education, research, and preventive health services in Jiangxi Province.

Jiangxi University of Traditional Chinese Medicine Affiliated Hospital conducted an in-depth evaluation of the DNTS‑9 time server, which was independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the hospital expressed high satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from navigation and positioning satellite systems such as GPS, BeiDou, GLONASS, and Galileo, and provides standard time services over the network via NTP/SNTP or other network protocols. In addition to serving as a primary-level network time synchronization device, the DNTS-9 can also function as a secondary-level time server, enabling more effective time synchronization in large-scale network environments. It can supply precise standard time signals to systems requiring accurate timing, including distributed networks, computer security systems, file management systems, e‑commerce systems, online B2B platforms, and cloud database storage and maintenance. The DNTS-9 has been successfully deployed in government, finance, mobile communications, public security, petroleum, electric power, transportation, industrial, and national defense sectors. Installation and operation of the DNTS-9 are extremely straightforward: simply connect the satellite receiving antenna and link the network port to a network switch to achieve time synchronization across all devices on the network.
