As the breadth and depth of computer applications continue to increase, there are more and more types of equipment and services in the network, and the number of servers is also increasing day by day. Traditionally, the time used by various servers and network devices is provided by the device's internal clock. Since the clock error of servers and network equipment is inevitable, although this error is not large every day, a large time difference will appear after a period of accumulation, resulting in inconsistent time among servers and network equipment in the network. For some important industries, this time inconsistency is fatal. Based on the above considerations, Jinan Weishang Electronics Co., Ltd. has independently developed a high-precision and high-stability network synchronization clock. Time sources such as />,
B,
, and rubidium atomic clocks synchronize the time of all servers and network devices in the network through the
protocol.
(
r, Network Time Protocol) is an international standard protocol for time synchronization in the network. It adopts the
/rr mode.
The client uses the
protocol to Get the accurate time from
server
server
.
Server
Server
The time of the server usually comes from an authoritative time source, such as atomic clock,
clock, time server on
, etc.
Not only corrects the time, but also can continuously track time changes and automatically adjust, so that clients using the
protocol can obtain reliable and accurate time synchronization from the network.
Network Synchronous Clock

Network synchronized clock
Timing scheme
Solution
: Clock synchronization of a single time server on the LAN
The device uses the received
/ Beidou information (serial port
+) as the time source, through
/ The protocol synchronizes all computers, routers, switches, intelligent controllers and other equipment in the network to realize network timing. Most operating systems come with their own services, and you just need to make some settings. Our company also provides
client software, and the installation and operation can also be synchronized.
Solution
: Redundant clock synchronization of two time servers in the LAN
The entire network is configured with a time synchronization system, consisting of two
master clocks, switches, networks and clients . Two
master clocks are placed in the switch cabinet of the computer room to provide timing to clients on the entire network in a
/ protocol. The two
master clocks are interconnected through
B code to work in redundant hot standby mode, which improves the reliability of the system.
Jinan Weishang is a professional manufacturer of
network synchronized clocks
. The equipment has a three-year free warranty and lifetime maintenance.
