Zhongxin Chuangwei provides a precision clock to the Shanghai Railway Bureau.

Recently The Shanghai Railway Bureau has released a time server. of the Demand , Beijing Zhongxin Chuang Company is actively cooperating For users A detailed plan has been prepared, and products independently developed and manufactured by Zhongxin Chuang have been recommended. DNTS- 82-RGB Clock Server As the product submitted for this tender, Zhongxin Chuang stood out by defeating competitors’ offerings thanks to its high‑quality products and comprehensive after‑sales service, ultimately… Awarded by the Shanghai Railway Bureau NTP server device Project 。

China Railway Shanghai Bureau Group Co., Ltd. is… China State Railway Group Co., Ltd. of large railway transport enterprises under management One of the 18 bureaus, commonly referred to as the “Shang Bureau.” It is located along the southeastern coast in the middle and lower reaches of the Yangtze River. Its jurisdiction and railway lines are primarily distributed in… Shanghai 、 Jiangsu 、 Zhejiang 、 Anhui and other regions. The area boasts a thriving industrial and agricultural sector, as well as robust domestic and international trade. With a dense population and abundant tourism resources, it is the busiest railway bureau in the country in terms of both passenger and freight transport.

Shanghai Railway Bureau To China–Singapore Innovation Independently developed DNTS- 82-RGB Clock Server Conduct an in-depth evaluation and arrive at the final results. All are superior to the parameter requirements. ， And Regarding our company’s product quality and after-sales service Also quite satisfied. ， Procured successfully and put into use. ！

Developed by Beijing Zhongxinchuang Technology Co., Ltd. DNTS-82-RGB A time server is a high-tech, intelligent device that can operate independently and is based on… High-precision clock synchronization server compliant with the NTP/SNTP protocol. DNTS-82-RGB The time server from Standard clock signal information is obtained from GPS or BeiDou geostationary satellites and transmitted over the network, enabling devices that require time synchronization—such as computers and controllers—to align with the standard clock. When both GPS and BeiDou receivers are used, a priority can be configured; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver has a signal, DNTS-8… 4 -OGB uses a built-in temperature-compensated crystal oscillator for timekeeping, with timing accuracy reaching 1E-9. DNTS-82-RGB Using standard clock information via TCP/IP network transmission, DNTS-8 4 -0GB supports multiple popular time‑synchronization protocols, such as NTP and time/UDP, and also accommodates custom‑defined time‑broadcast packets over a configurable UDP port. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. DNTS-82-RGB Also supports The broadcast operating mode of the SNTP protocol.
