With the rapid development of modern society, higher requirements for high-precision time and frequency have been put forward, especially the development of modern digital communication networks and the construction of information highways. Many political, cultural, technological and social information coordination have been established. Based on strict time synchronization, time synchronization equipment is urgently needed in fields such as communications, electric power, radio and television, transportation, financial securities, computer networks, production line operation and management, and national defense.
The time server
uses the global positioning satellite (
) signal as the time reference source.
The time base contained in the satellite signal is synchronized with the coordinated global time (
), and the long-term frequency stability reaches the level of the cesium atomic clock
, which is equivalent to
30,000 years. Slow seconds. Using this signal as a time base to adjust the local time can eliminate the time accumulation deviation caused by the low accuracy of the local clock and greatly improve the timing accuracy of the server. Weishang products use professional
timing receivers, which have fast satellite collection speed and reliable locking.
Protocol (
r) is an internationally accepted network timing protocol. Its principle is that the client initiates a time poll to the server every once in a while. According to a certain filtering algorithm, the time deviation between the server and the client and the propagation delay caused by network transmission are calculated. According to these two parameters Adjust the client's local time to be consistent with the server's. Compared with other time calibration protocols, the
protocol can eliminate the impact of network propagation delay and therefore can provide high-precision timing services. For specific protocol descriptions, please refer to the latest standard documents
R3 and
R3. Weishang products are compatible with various versions such as
/3/.
Weishang products have a variety of models to choose from,
We have
adaptive Ethernet ports,
We have
Adaptive Ethernet ports
There are
adaptive Ethernet ports. The network ports are physically isolated from each other. When one network port fails, it will not affect other The network port works normally and data security is fully guaranteed.
The address can be set to the same network segment or different network segments, and two network ports can be set to the same address
for backup.
