Description
Technical field
The present invention proposes a kind of electric line foreign matter and disappearance intelligent video on-line monitoring system, belongs to intelligent grid skill
Art field.
Background technology
Along with the fast development of national economy, electric power has become as product indispensable in daily life and commercial production
Product, the stability of electric power transmission is the most increasing on the impact of social development.Along with run the time limit growth, transmission line of electricity and
Electric component unavoidably there will be disappearance or attachment foreign body, transmission line of electricity attachment foreign body not only can make power transmission line the limit electric discharge away from
From shortening, and during the through adjacent lines of foreign body, also can cause transmission line of electricity phase fault or open circuit, transmission line of electricity is original electrically
The disappearance of parts also can cause transmission line malfunction, causes large-area power failure, jeopardizes the safe operation of power system.Therefore need
Electric line foreign matter and disappearance thereof are monitored, it is ensured that line security stable operation.
At present, the electric line foreign matter monitoring method using manual patrol is monitored, due to the long-term work of transmission line of electricity more
Making in field, geographical conditions are various, and weather is complicated and changeable, and personal monitoring's difficulty is big, and cost is high, and inefficiency is affected by weather
Seriously.Accordingly, it would be desirable to a kind of can replace the low cost of manual inspection, high efficiency, by the less system pair of inside even from weather
Electric line foreign matter and disappearance are monitored in real time, to meet the demand of electrical network intelligent development and management.
Additionally, developing rapidly along with intelligent video technology, the most also there is employing Computer Vision mode to transmission of electricity
The technology that circuit foreign body and disappearance are monitored, Chinese patent " foreign bodies on transmission lines species detection platform " (application number:
201510650481.5), and Chinese patent " detection method of a kind of transmission line of electricity regular maintenance " (application number:
201510587530.5), all use the mode of image procossing that electric line foreign matter is detected, but the most not to transmission of electricity
The original electric component of circuit is identified, and the original electric component of transmission line of electricity is serious on electric line foreign matter detection impact；Especially
Lack the function judging the most through adjacent lines of foreign body, it is impossible to the harm to transmission line of electricity of the accurate evaluation foreign body；The most do not disappear
Except transmission line of electricity because of icing snowberg, wave, sag change on electric line foreign matter and disappearance monitoring impact, exist many lack
Fall into, be badly in need of further improving.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention proposes electric line foreign matter and disappearance intelligent video on-line monitoring
System, in real time monitoring accurate recognition electric line foreign matter and disappearance, eliminate simultaneously powerline ice-covering snowberg, wave, sag
Change electric line foreign matter and the impact of disappearance monitoring, distinguish the extent of injury of foreign body, and accordingly foreign body and disappearance are carried out
Early warning or warning, solve that tradition inspection method cost is high, efficiency is low, serious and can not monitor in real time by inside even from weather
Problem.
The technical solution adopted for the present invention to solve the technical problems is:
Described electric line foreign matter and disappearance intelligent video on-line monitoring system, including video image acquisition module (1), data

Module (3) carries out early warning；During early warning, system distinguishes the foreign body extent of injury, the foreign body less to transmission line of electricity harm, only identifies also
Carry out early warning, do not report to the police.Such as, birds are short stay on power transmission line, can't cause transmission line malfunction, and system distinguishes this
The foreign body that class hazardness is less, prevents the generation of false alarm.
If there is the disappearance of original electric component (5), then calculate position, quantity that original electric component (5) lacks,
Report to the police through communication module (3).Report to the police during original electric component (5) disappearance, be possible to prevent because electric component lacks
The generation of the accident caused, improves the stability that route runs.
Data Analysis Services module (2) according to the profile of transmission line of electricity (4) and the profile of alien material (6) in image information
In difference, identify alien material (6) the most through adjacent lines, if it is, it is alternate short to be likely to result in transmission line of electricity (4)
Road, calculates the position of alien material (6) of through adjacent lines, size, quantity, reports to the police through communication module (3).Foreign body
The generation of the major accidents such as transmission line of electricity phase fault or open circuit may be caused during through adjacent lines, identify foreign body and power transmission line
The connected relation on road, and report to the police accordingly, stability and reliability that circuit runs can be improved.
System includes hand-held set (7) and central server (8), Data Analysis Services module (2) through communication module (3) to hands
Hold machine (7) or central server (8) and send early warning and warning message, in order to operations staff and administration section can timely respond to,
Process in time.
When transmission line of electricity (4) foreign substance information is analyzed processing by Data Analysis Services module (2), eliminate transmission line of electricity
(4) icing snowberg, wave, sag change on transmission line of electricity (4) foreign body and disappearance monitoring impact.Data Analysis Services module
(2) to exist icing snowberg, wave, sag change transmission line of electricity (4) video or image information be analyzed process, identification is deposited
Icing snowberg, wave, sag change transmission line of electricity (4) geological information, in conjunction with data analysis and processing module (2) prestore defeated
Electric line (4) original video or image, analyze icing snowberg, wave, sag changes the change that causes transmission line of electricity (4), and
According to analysis result eliminate transmission line of electricity (4) because of icing snowberg, wave, sag change on foreign body and disappearance monitoring impact, keep away
Exempt from wrong report, improve foreign body and the accuracy rate of disappearance identification.
Compared with prior art, present invention have the advantage that
The method utilizing Intelligent video-image to process carries out the monitoring of electric line foreign matter and disappearance, have intelligence degree high,
The advantage such as simple to operate, with low cost, convenient for installation and maintenance；System can be run, without manual intervention, real-time online by Automatic continuous
Detection, less by inside even from weather, greatly reduce operation maintenance personnel workload.
Electric component original to transmission line of electricity and alien material make a distinction identification, it is to avoid by electric component as external different
Thing causes wrong report, improves the accuracy of monitoring foreign bodies；Original electric component disappearance is reported to the police simultaneously, be possible to prevent because of electricity
The generation of the accident that gas parts disappearance causes, improves the stability that route runs.
Distinguish the alien material extent of injury, it is judged that alien material and the connected relation of transmission line of electricity, form transmission line of electricity and go out
Grading forewarning system and warning, beneficially operations staff after existing foreign body process in time.
Electric line foreign matter and missing information are analyzed process time, eliminate powerline ice-covering snowberg, wave, sag
Change electric line foreign matter and the impact of disappearance monitoring, be effectively improved accuracy and reliability that system is run.
