Congratulations to the Second People’s Hospital of Henan Province on its procurement of the Zhongxin Chuangshi clock synchronization equipment project.

Congratulations to the Second People’s Hospital of Henan Province on its procurement of the Zhongxin Chuangshijie clock synchronization equipment project.

 

Recently, the Second People’s Hospital of Henan Province issued a procurement announcement for time servers. Beijing Zhongxin Chuang Company proactively collaborated with the hospital to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑84‑OGBC 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 Renmin University of China in Beijing.

Henan Provincial Second People’s Hospital (Affiliated Hospital of Henan Medical College) is a tertiary general hospital integrating medical care, education, scientific research, rehabilitation, and preventive health services. It commenced operations on October 16, 2011. The hospital currently employs nearly 700 staff members, including over 80 with senior professional titles, more than 130 with intermediate titles, and over 60 holding doctoral or master’s degrees. The planned site covers 300 mu, with an overall capacity of 2,000 beds; the first phase comprises a building area of over 56,000 square meters. At present, 820 beds are in operation, and the hospital offers departments such as Emergency Medicine, Internal Medicine, Surgery, Obstetrics and Gynecology, Pediatrics, Neonatal Intensive Care Unit (NICU), Oncology, Otorhinolaryngology, Intensive Care Unit (ICU), Dermatology, Traditional Chinese Medicine, Rehabilitation Medicine, Integrated Traditional Chinese and Western Medicine for Infertility, Anesthesiology, the Operating Room, the Laboratory, Radiology, Pathology, and the Functional Monitoring Department. The facility is equipped with advanced diagnostic and therapeutic equipment, including a GE 256‑row, 512‑slice CT scanner, a Philips DSA system, Siemens 3.0T and 1.5T MRI scanners, spiral CT scanners, and digital radiography (DR) systems.

Henan Provincial Second People’s Hospital conducted an in-depth evaluation of the DNTS‑8 time server independently developed by Zhongxin Chuang. The results exceeded all 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-84-OGBC time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is a high-tech, intelligent, stand-alone clock synchronization server that operates based on the NTP/SNTP protocols and delivers high-precision time. The DNTS-84-OGBC can obtain standard clock signal information from GPS or BeiDou geostationary satellites, as well as from CDMA networks. This information is transmitted across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize with the standard clock. Additionally, when using GPS, BeiDou, and CDMA receivers, users can define priority levels; by default, BeiDou takes precedence, with GPS as a backup and CDMA last. If all three receivers lose signal, the DNTS-84-OGBC switches to its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-84-OGBC transmits standard clock information over TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, while also accommodating custom time‑broadcast data packets defined by Zhongxinchuang Technology, with configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC-123 and RFC-37. Furthermore, the DNTS-84-OGBC supports the broadcast mode of the SNTP protocol.
