Time synchronization products
(
Timing instrument
, Beidou time synchronization device
, time synchronization product generator) overview< br/> . Introduction
The
time synchronization products
produced by Jinan Weishang Electronics Co., Ltd. are mainly targeted at the application characteristics of power systems. They adopt a flexible plug-in card design, adopt a redundant structure, and support dual power supplies. Hot backup, dual system hot backup and dual B hot backup, with high-precision timing performance and superior timing performance, can be grouped together or individually.
The device provides a variety of timing signals, including: pulse, serial timing messages,
B (DC, AC
code),
, network timing and other timing interface types include : Various timing signals and interface types such as optical fiber,
R level,
level, null contact and network port can be flexibly selected and configured.
The device is suitable for various networking modes such as basic mode, mutual backup mode, master-slave mode and master-standby mode. It is mainly used in the main station system centered on the dispatching automation system and the sub-station system centered on power station monitoring (including power plants, substations, switch stations, etc.) to provide stable, reliable and high-precision time information.
. Main functional features
The device has the duality of main clock and extended clock. The equipment clock source can be flexibly configured, and it can be configured with Beidou or
satellite input board, which can be used as the main clock system application. The configuration code input board or network board can be used as an extended clock application.
This product can receive Beidou and
satellite signals at the same time, realize Beidou satellite and
dual system redundancy backup, provide long-term time stamp information, synchronize and provide external timing, and can also use external input sources ( Including
B (
and network timing) to synchronize the time base and provide external timing. When neither the satellite source nor the external clock source is available, the system's internal clock control algorithm stably provides high-speed timing within a certain period of time. Precision time information. The advanced clock control algorithm automatically selects the tracking source and switches the tracking source losslessly. Beidou and
satellite sources or between satellite sources and external input sources can automatically switch to input two
code information to achieve dual system redundancy backup and provide time stamp information. The two code sources can be automatically switched and lossless switching can be achieved.
Specific features are as follows:
Flexible configuration, supports hot-swappable function
Dual power supply redundant hot backup

,
,
, self-programming pulse and
and
Code etc.
AC code
High amplitude is
3~
continuously adjustable, low amplitude meets
~
modulation ratio requirements
Output types include: optical fiber,
R, empty contact, etc.
Can support
R and
level formats. The message output baud rate can be configured. The message format can be configured. Select the configuration and can also customize it according to user requirements
It has the functions of cycle measurement, power frequency clock and power frequency clock difference output. The cycle measurement accuracy is
weeks and the power frequency clock difference measurement accuracy
.
All signal output ports are photoelectrically isolated and the electromagnetic anti-interference meets the
/ time synchronization system standard requirements of the power system.
