Network timing server is for computers, automation devices, such as time calibration and development of high-tech equipment, the product can be from GPS satellites (BeiDou satellites, CDMA, B-code interface, PTP) to obtain the standard time signals, will be these signals through a variety of interfaces (NTP/SNTP, serial port, B-code, PTP, Pulse) to the equipment in the automation system that needs time information (computer, protection device, fault recorder, event sequence recording device, safety automation device, remote RTU), so that there is a standard time source in the system, thus achieving the time consistency of the whole system.
HR series network timing server internal ARM embedded system technology production, to high-speed chip control, no hard disk and fan design, high precision, good stability, strong function, no accumulation of error, not subject to the geographical climate and other environmental conditions, cost-effective, simple operation, fully automatic intelligent operation, free of operation and maintenance, and suitable for unattended. The product can provide precise standard time signal and time stamping service for computer network system, electric power automation system, water conservancy automation system, e-commerce system, online B2B system and database preservation and maintenance system, etc. It has been successfully applied in the fields of government, finance, communication, transportation, broadcasting, security, electric power, water conservancy, national defense, medical treatment, education and IT.
Two, network timing server product features:
◆ High precision, serial/pulse up to 30ns, NTP client better than 2ms, time synchronization fast.
◆ Dual-CPU simultaneous work, 32-bit CPU dual-core processor, using DSP/CPLD to complete the real-time high-speed processing;
◆ Expandable unlimited number of independent physical isolation of the 10/100M network port (each port has an independent MAC address), each port can be flexibly configured for use in different subnets and physical isolation network;
◆ The network server can be used in a variety of different networks and physical isolation network;
The network server can be used in a variety of different networks and physical isolation of the network.
◆ As a first-class time server, it can provide time service for tens of thousands of clients, servers and workstations at the same time.
