With the rapid development of computer networks, network applications have become very common. Network systems in fields such as electric power, finance, communications, transportation, radio and television, security, petrochemicals, water conservancy, national defense, medical care, government agencies, etc. need to be deployed on a large scale. The scope keeps the computer's time synchronized and the clock accurate, but the computer's time is generated based on the computer's crystal oscillator oscillating at a fixed frequency. Due to the difference in crystal oscillators, computer time accumulation errors will occur. From the perspective of business impact, because of the inconsistency in time, it is impossible to infer the specific time when the business occurred. From the perspective of security impact, the logs of all devices (such as in video surveillance) must reflect accurate time, because the time is not uniform, security-related tools will be useless.
Therefore, it is very necessary to have a good standard time timing equipment. In order to adapt to the increasingly sophisticated time requirements in these fields, Jinan Weishang Electronics Co., Ltd. has carefully designed and independently developed the
series
LAN time synchronization
. The device is based on
satellite The signal is the time base, and Beidou satellite,
time source, etc. can be selected at the same time. The internationally popular
R service is embedded to synchronize all computers in the network with
/ protocol.
Controller and other equipment to achieve network clock synchronization.

Series
LAN time synchronization
There are three models to choose from:
With individual
/adaptive Ethernet ports
There are
physically isolated
/adaptive Ethernet ports
that can be configured at the same time
-physically isolated
/adaptive Ethernet ports Ports can meet the requirements of different customers. When a certain network port fails, it will not affect the normal operation of other network ports, fully ensuring data security.
LAN time synchronization
Working mode
Active
/Passive symmetrical mode: One-to-one connection, both parties can synchronize or be synchronized by the other party, the party who first sends the application to establish the connection Works in active mode and the other in passive mode. This method is suitable for configuring redundant time servers.
Client
/server mode: basically the same as active
/passive mode. The only difference is that the client can be synchronized by the server, but the server cannot be synchronized by the client.
Broadcast mode: One-to-many connection, the server actively sends out time information regardless of the mode the client is working in, and the client adjusts his or her time based on the information. At this time, the network delay is ignored, so there is a difference in accuracy. loss.
