Overview:
With computer technology, network communications technology
and power system protection and automatic control technology, automation of the
substation operation has improved continuously, greatly reducing the human
operator accidents, so that the unmanned substation gradually become possible,
and has become a power industry System trend of development. Has achieved a
production run equipment at the scene of data, sent to the remote state of the
dispatch center, dispatch center can also be the site of the remote control and
regulation equipment, which is often called the telemetry, remote, remote
control and remote tune. As the unmanned substation if it only has four remote
is not enough, because the dispatch center can not understand the situation
caused some safety precautions such as "fire prevention, anti-theft" could not
be realized, therefore substation still need someone guard day and night. With
computer technology, multimedia technology and the rapid development of
communication technology, images, sound and other multimedia digital signal
processing and long-distance transmission technology has been quite mature,
mature technology that will power the introduction of automated scheduling
system, in the remote base On the fifth increase in remote - remote vision, and
achieve security, fire protection, import and export management, will realize
the true sense of "unmanned."
In order to strengthen the re-substation and
unmanned substations in production safety, anti-theft security, fire control and
other aspects of the comprehensive management level, to achieve the goal of a
first-class, more and more power companies are considering building a
centralized remote video monitoring system. It can all substation on the scene
to conduct real-time video monitoring, the substation will be monitored, as the
main control room, high-pressure rooms, equipment, broken electrical appliances,
isolation switch, outdoor venues such as the scene image through communications
networks to collect real-time transmission Control Station or local dispatch
center at the same time can be conducted in accordance with a variety of digital
video, stored in the server after the call. The important substation, the
Council leadership and staff scheduling can be through corporate computer
networks, using desktop computer, real-time video monitoring of the substation
or call digital video.
In recent years, power companies in the
province-wide computer information gradually building wide-area network, the
substation is to build long-range surveillance images in the computer
information WAN one of the important applications.
Power system within the
complex types of production equipment, the number of huge, wide geographical
distribution, artificial maintenance difficulties. At the same time, increase
efficiency and cut personnel to meet the requirements of modern management,
production at the closed-circuit television monitoring system in reliability,
ease of use and easy to maintain, especially for remote monitoring in a higher
demand. At the same time, the power system of information network construction
in the quality and speed of the network system is among the best, which is based
on the application of video surveillance network has provided good conditions.
Based on the embedded video server, mainly used in unmanned substations, the
Electric Power Bureau / plant comprehensive monitoring system, on-site
production scheduling command system and to disasters and emergencies emergency
treatment. To ensure that the monitoring equipment in the building of reliable
operation and the safety of personnel.
Second, the network topology:

analog video surveillance digital collection, image compression, monitoring data
processing, alarm signals in the collection, transmission networks, and other
functions. It could be the front-end analog signal processing at the same time
as the real-time digital high-definition images released to the network, users
can achieve more at the same time monitoring the same or different images of the
scene, really video sharing
2, several Taiwan with the back-end
monitoring software for monitoring the computer components, software reference
section V.
Most of the conditions within the network has its own
substation E1 lines, images can monitor the use of E1 lines to transmit to the
centralized control center. E1 bandwidth to 2 Mbps, so I can transfer up to
eight real-time image.
Fourth, the system advantages
1, you can
use the station has been the transfer E1 lines image.
2, good stability,
not Dead, the use of embedded operating system.
3, free from virus
attacks, the system uses VXWORKS operating system, WINDOWS system of the virus
can not be invaded.
4, functional and high integration, a dynamic IP

the different camera plans Like the surveillance, easy-to-use, and can take
photographs, images loop, and other settings.
2, and video playback
Software in the video has done a great improvement, software does not
play in the case of video can also be carried out, great save CPU resources, a
P4 computer can also record images 30 to 40 channel.
To enhance the
flexibility of video, software also provides a wide range of video, a mobile
video, automatic video, video manually, a single video, pre-point video, alarm,
such as video.
Mobile video is moving when the video server to the scene
detected in the automatic image campaign on the situation recorded (for example,
some people through the camera before, the server will automatically record to
the local computer).
Automatic video automatic video means that the
software installed in the video server time, when the client's computer systems
are running into the time set automatically after the time period that this time
the images recorded.
Video video manually using manual means, only
through artificial controls can play a role, which set a user-to manual recorder
then only for users to stop it, it will stop the video.
