Congratulations to the Shandong Provincial Police General Hospital on its procurement of Zhongxin’s clock synchronization equipment.

Congratulations Shandong Provincial Police General Hospital has procured a new‑generation clock synchronization device.

Recently, Shandong Provincial Police General Hospital A procurement notice for a time server has been issued. Beijing Zhongxin Chuang Company has actively collaborated to prepare a detailed proposal for the user and recommended a product independently developed and manufactured by Zhongxin Chuang. As the bidding product for this round, the DNTS‑9 model underwent a fiercely competitive tender process. Relying on its high‑quality products and comprehensive after‑sales service, Zhongxin Chuang outperformed competitors and ultimately secured the project at the Shandong Provincial Police General Hospital.

Shandong Provincial Police General Hospital [1] Located at No. 134 Yingxiongshan Road, Jinan City, it is a non-profit, Grade II-A general hospital.

Shandong Provincial Police General Hospital To China–Singapore Innovation Independently developed DNTS-9 Time server Conduct an in-depth evaluation and arrive at the final results. All Exceeds 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. The DNTS‑9 is an advanced, intelligent, high‑precision NTP network time server. It 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. Devices on the network that require time synchronization—such as personal computers, servers, and controllers—can thereby synchronize with international standard time.

Use simultaneously The GNSS satellite receiver allows priority settings and supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations; each receiver can be configured to operate in timing mode either independently or in conjunction with others. When both receivers and all other available time sources lose signal, the DNTS‑9 relies on its built-in temperature‑controlled crystal oscillator or rubidium atomic clock for holdover, continuously providing time services to external users.

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 provides high‑precision standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors.

The DNTS-9 network time server is extremely easy to install and use: simply connect the satellite receiving antenna and plug the network port into a network switch, and you can achieve time synchronization across all devices on the network.
