The synchronized clock
is composed of
Beidou satellite receiving unit,
highly stable crystal oscillator frequency source,
(programmable logic device) and
3 It is composed of a time unit, a display and system management unit, a power supply unit, a network communication unit, and setting and special timing software composed of a single-chip microcomputer.
The time source can be configured
, Beidou timing receiver (user optional), rubidium atomic clock or constant temperature crystal oscillator (user optional). This machine not only has a network port, but also provides users with four channels
R3 interface can meet the time adjustment needs of devices that cannot access the Internet.
This device is an intelligent network time server that works based on standard
/ protocols. All devices in the network that support the
/ protocol, such as computers, routers, etc., can synchronize with the standard time source from this server. Two
R network ports are configured, based on standard
/protocol and
/adaptive.
Jinan Weishang Electronics Co., Ltd.’s products are produced using surface mount technology, controlled by high-speed chips, without hard disks and fan designs, with high precision, good stability, strong functions, no accumulated errors, and are not affected by regional climate, etc. It has the characteristics of limited environmental conditions, high cost performance, simple operation, fully automatic intelligent operation, and maintenance-free, and is suitable for unattended operation. The device can provide precise standard time signals and time stamp services for computer networks, computer application systems, process control management systems, e-commerce systems, online BB systems, and database storage and maintenance systems.
Function of synchronized clock
The panel can display:
①Hour, minute, second, year, month and day Beijing time.
② Positioning and status information (longitude, latitude, positioning valid
/invalid and the number of satellites currently received).
③ Beidou
(
) status information.
The clock device receives
dual redundant time sources with Beidou satellites to provide a unified standard time for each node of the network. It has a dual network port network timing function that is physically isolated from the network. Applicable to a variety of operating systems (
/routers
workstations
/servers, etc.).
Beidou
(
)
\Time source is automatically selected, preferred
. That is, you can automatically choose to receive Beidou or receive to synchronize the local clock. The default is to receive
synchronization when powered on.
3 Internal configuration
A highly stable constant-temperature crystal oscillator is used as the frequency source and has a timekeeping function.
There are six
indicator lights, respectively indicating:
light
whether the working status of the
satellite is received (normal, flashing once per second, abnormal or not positioned) When the connection is normal, it goes out)
Light
Network link status (when not connected to the Internet, it goes out; when the link is normal, it stays on)
Light
The internal working status of the network module (when it is normal, it lights up for one second, When it is abnormal to be off for one second, it flashes quickly)
Lamp
Internal frequency source
/The working status of the local clock (flashes once per second when normal).
When selecting to receive
satellite synchronization, location information (latitude, longitude and altitude) can be automatically sent to
every minute.
If the
satellite input position information cannot be received during
satellite mode, it can also be passed through the
compatible machine (< br/>Environment) Enter the location information of the receiving point.
Support standard
/protocol,
/Ethernet adaptive.
There are a variety of output interfaces, which are suitable for both network environments and time correction of other external devices (computers, servers, large clock displays, etc.). The output interfaces are as follows:
R network interface two channels
, R3 interface four channels,
second pulse (
level) one channel.
Supports network time protocols:
,
,
,
, and is compatible with the dedicated client time correction software configured on this server.
Time server-side setting software: dedicated
address and network parameter setting software to ensure network reliability and security.
Key operations can view internal status information and various working parameters such as date and location.
Fully modular plug-and-play structure design supports hot-swappable boards, flexible configuration, and easy maintenance. It also provides convenience for adding timing ports during future on-site network reconstruction and expansion.
