Technical field

The present invention relates to transmission of electricity corridors to monitor field, supervises more particularly to a kind of transmission of electricity corridor screen of trees based on air remote sensing Examining system.

Background technique

Transmission line of electricity is energy transport lifeblood needed for carry national product and life, is the important composition of network system The safe and stable operation of part, transmission line of electricity is particularly important to national product and power grid operation.

With the raising of Transmission Line Design and construction level, the facilities such as bird-resistant, arrester, on-line monitoring are installed to Position and people afforest the reinforcement for consciousness of protecting a forest, and the trees in corridor of transmitting electricity, which are increasingly becoming, influences transmission line safety operation Big problem.Transmit electricity trees in corridor to the threat of transmission line of electricity from its own relative to conductor height safe distance not It is enough, cause the phase fault of route to the direct contact of conducting wire or the mediate contact under wind action so as to cause trees, And cause to trip.It is serious also to cause broken string, the occurrence of falling bar.It is huge not only generation to be operated normally to this route It influences, more likely influences the normal operation of entire power grid.

Aerial remote sens ing technique is the remote electromagnetic wave information for obtaining object using certain technical equipment and system, And the technology analyzed and applied according to the feature of electromagnetic wave.Airborne LIDAR is a kind of active earth observation systems, is nine Grow up and put into an emerging technology of commercial applications at the beginning of the ten's by western countries first.Its integrated laser ranging skill Art, computer technology, Inertial Measurement Unit (IMU)/DGPS differential position are in one, and the technology is in three-dimensional spatial information Aspect is obtained in real time and produces important breakthrough, provides a kind of completely new technology to obtain high-spatial and temporal resolution geospatial information Means.High-precision earth's surface digital elevation model can be generated after related software data processing in airborne LIDAR data (DEM) and tree crown surface number model (DSM).

It has the characteristics that high degree of automation, is influenced that small, data are with short production cycle, precision is high by weather.

It is directed to such case, a kind of transmission of electricity corridor screen of trees monitoring system based on air remote sensing of the present invention is, it can be achieved that defeated The real-time monitoring of electric corridor screen of trees.

Summary of the invention

The present invention is by constructing a kind of transmission of electricity corridor screen of trees monitoring system based on air remote sensing, by aviation aircraft (1) the airborne LiDAR (2) carried carries out the earth's surface trees multiecho detection of wide area, and detection result is passed through communication module (3) data processing module (4) on ground is transferred to by earth's surface digital elevation model (DEM) and tree crown surface number model (DSM) analytical calculation obtains region height distribution data, then folds region height distribution data input grid power transmission GIS Add analysis module (5) to be overlapped analysis, show that at a distance from transmission line of electricity, overlay analysis result is inputted for transmission of electricity corridor trees Data management module (6) realizes transmission of electricity corridor trees data management of sequence variation at any time at a distance from transmission line of electricity, simultaneously It is compared with according to the early warning value of transmission line safety distance setting, reaches early warning value and send alarm signal immediately.Alarm letter Number include transmission of electricity corridor trees at a distance from transmission line of electricity and grid locational coordinate, is mentioned for transmission of electricity corridor screen of trees cleaning work For technical support.

Detailed description of the invention
