NTP network time service server is a high-tech product developed independently by our company, mainly for computer, automation equipment and other network equipment. NTP network time service server receives external clock reference signals such as GPS satellite, Beidou satellite, PTP, B code, and NTP network time service server is controlled by intelligent clock source. The algorithm realizes intelligent switching of multi-clock sources and outputs high precision and reliable clock signals and clock information.
_NTP network time service server makes use of satellite bidirectional time service function to construct the whole network clock synchronization network of the whole power system and realize the whole network clock synchronization.
_NTP network time service server can construct centralized monitoring and remote maintenance of the clock synchronization system of each factory and station by using satellite bidirectional communication function, so as to improve the operation reliability of the equipment.
NTP network time service server is manufactured by surface mounting technology, controlled by high-speed chip, no hard disk and fan design, high precision, good stability, strong function, no accumulation error, not limited by environmental conditions such as regional climate, high performance-price ratio, simple operation, fully automatic and intelligent operation, free of operation and maintenance, suitable for use. No one is on duty.
_NTP network time service server has standard RS232, RS422/485, 1PPS/PPM/PPH, IRIG-B, DCF77, NTP/SNTP network time-to-time interface forms, which can meet the needs of different equipment, and is widely used in power, finance, communications, transportation, radio and television, security, petrochemical, metallurgy, water conservancy, medical, education, IT and other fields. Domain.
Main Use of NTP Network Time Server
_Display the clock to the clock display screen which the operator observes or records manually.
Devices (systems) for recording clock-related information: such as fault recorder, event sequence recorder, RTU remote control device, computer monitoring (monitoring) system, power grid pre-decision analysis system, SCADA/EMS system for dispatching at all levels, WAMS system, power billing system, water dispatching automation system. Chemical System, Power Plant Unit Control System, Power Market Trading System, Distribution Network Automation System, Load Control and Power Management System, Communication Network Monitoring System, Power Plant and Scheduling Production Information Management System, Power Enterprise Information Management System (MIS), etc.
It is necessary to record the control device (system) of its action clock, such as the computer protection device, the background system of substation monitoring system, the power grid security automatic device, etc.
The working principle is based on clock synchronization, such as lightning positioning system, synchronous phasor measurement unit (PMU), line fault traveling wave location device, etc.
Systems requiring recording data at the same time, such as protection information management machine, power grid frequency evaluation system by second, etc.
Used in relay protection test to test line longitudinal protection (high frequency phase difference protection device)
Clock Synchronization in Large LAN
Other devices (systems) requiring uniform clocks
