Scope of Application
The PRS-7921 Comprehensive
processing unit can be used as the intermediate hub between the online
monitoring equipment in the station and the higher-level dispatch
monitoring system. It receives data sent by the online monitoring device
in real time, aggregates, displays, processes, analyzes and stores the
data, implements control of the online monitoring device, and carries
out standardized communication with higher-level system.
Advantages
01
Human-computer interface
A user-friendly graphical human-machine interface is provided via the WEB or CS client,, which has functions of data configuration, browsing, debugging, and data export.
02
Convenient communication modeling
The 61850 scd modeling tool is provided for one-stop model modification and import, station communication modeling, and one-click export of upward communication scd file to the main station.
03
Data transmission, processing and storage
It supports the comprehensive processing unit to call the real-time monitoring data of online monitoring device, and supports the main station system to call the real-time monitoring data of comprehensive processing unit. The unit processes the received data, and supports the list, graphic display and query of historical data.
04
Monitoring device management
It can manage and configure the basic information of online monitoring device under its supervision, including the device type, communication parameters, and fixed values, and it also supports real-time reception and forwarding of the fixed values of online monitoring device issued by the main station system.
05
Self-inspection and self-recovery
It can improve the self-inspection information and send it to the main station, record the operation logs and self-recover from abnormal conditions, and the stored data will not be lost.
06
System configuration and maintenance
Equipped with engineering configuration tools, it supports remote maintenance of the main station system using SSH, telnet, and remote debugging tools.
