Congratulations to Zhongxin Chuang on winning the bid for the clock synchronization equipment project at Linshu County People’s Hospital.

Congratulations to Zhongxin Chuang on winning the bid for the clock synchronization equipment project at Linshu County People’s Hospital.

Recently, Linshu County People’s Hospital issued a procurement announcement for a time server. Beijing Zhongxin Chuang Company proactively collaborated with the hospital to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑8 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 Linshu County People’s Hospital time‑server project.

Linshu County People’s Hospital was founded in 1949. Through the dedicated efforts of several generations, it has grown into a comprehensive Grade II-A hospital with complete functions, state-of-the-art equipment, and robust technical expertise. It is recognized as a National Baby-Friendly Hospital, a remote consultation partner of Shandong Provincial Hospital, a medical‑technical cooperation hospital of the PLA Navy General Hospital, a medical‑technical cooperation hospital of Qingdao Fuwai Hospital, a medical‑technical cooperation hospital of the PLA Rocket Force Medical Center, and a technical collaboration hospital of the Ophthalmology Hospital of the China Academy of Traditional Chinese Medicine.

Linshu County People’s Hospital conducted an in-depth evaluation of the DNTS‑8 time server 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-84-OGB 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. The DNTS-84-OGB time server obtains standard clock signal information from GPS or BeiDou geostationary satellites and transmits this information across the network, enabling devices requiring time signals—such as computers and controllers—to synchronize 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, the DNTS-84-OGB relies on its built-in temperature-compensated crystal oscillator for timekeeping, achieving a timing accuracy of up to 1E-9. The DNTS-84-OGB disseminates standard clock information via TCP/IP networks and supports multiple popular time‑broadcasting protocols, including NTP and time/UDP, as well as Zhongxinchuang’s proprietary time‑broadcast data packets 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. Additionally, the DNTS-84-OGB supports the broadcast mode of the SNTP protocol.

Product dimensions	19-inch 1U
Receiver	Built-in GPS and Beidou receiver
Built-in clock	Built-in temperature-compensated crystal oscillator; even when satellite signals are lost, it continues to output a standard time signal.
Liquid crystal display	LCD displays time in two lines of 20 characters each, showing the current time, the number of satellites, and the device’s operating status. LEDs indicate power status, satellite lock status, holdover operation, alarms, and NTP validity.
Throughput	Can handle 2,000 time requests per second per port.
Local Alarm	Supports SNMP alarms and local dry-contact alarm outputs, with a maximum current of 10 A.
Output interface	RS232/485, IRIG-B, 10M, 1PPS, 10 MHz sine wave output, BNC connector 1 PPS output, BNC connector IRIG-B code output, BNC interface IRIG-B code input, BNC interface RS232 output, supports the TL1 protocol.
Input interface	Serial port input; time can be set manually, and it can serve as an external clock source.
Timekeeping function	Even when satellite signals are lost, it must still output a standard time signal, with the temperature‑compensated crystal oscillator achieving an accuracy of better than 1 × 10⁻¹².
Encryption Verification	Provides MD5 encryption verification functionality.
Network management functions	It features comprehensive SNMP network management capabilities.
Feature Expansion	Supports expanding to select other functional modules.
Settings Management	Supports configuration and management via web pages, Telnet, and other methods.
Timekeeping Record	Time‑synchronization logs can be viewed via the web interface and Telnet; the installed software can store an unlimited number of records.
UDP operating mode	Provides the UDP broadcast protocol, enabling connection to electronic clock LED displays. You can configure at least eight UDP remote IP addresses and port numbers: Output the newly created science and technology time data packet: A total of 32 bytes, with the following details: Offset Description 00...01 year (00...99) 02...03 months (01...12) 04...05 days (01...31) 06...07 hours (00...23) 08...09 points (00...59) 10...11 seconds (always 00) 12 weeks (1-Mon, 2-Tue, ...) 13 Daylight Saving Time Flag (0-no, 1-yes) 14 String terminator, ‘\0’ 15 String terminator, ‘\0’ 16...19 32-bit CET/CST time in UNIX format 20...23 32-bit GMT time in UNIX format 24...31 All 0
