In accompanying drawing be only some embodiments of the present invention, for those of ordinary skill in the art, do not paying
On the premise of going out creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is one aerial line inspection tour system structural representation of the present invention;
Fig. 2 is that image acquisition device collection picture frequency determines schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly
Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than
Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, the aerial line inspection tour system of the present embodiment, including: unmanned plane 1 and ground control to set
Standby 2, unmanned plane 1 is provided with: image acquisition device 11, wireless communicator 12 and airborne computer 13.Airborne electricity
Brain 13 connects image acquisition device 11 and wireless communicator 12 respectively, and is controlled with ground by wireless communicator 12
Control equipment 2 connects, and the airborne computer 13 for unmanned plane 1 communicates with GCU 2.Wherein, nothing
Line communicator 12 uses 4G signal processing.
Airborne computer 13 includes flight path by what wireless communicator 12 received GCU 2 transmission
Control instruction, and control unmanned plane 1 along flight path fly.In flight course, image acquisition device 11 will
Circuit image along flight path collection transmits extremely airborne computer 13 and stores.Airborne computer 13 call wire simultaneously
The coordinate position of road image, and by the fault picture of the circuit image that gathers and wherein pre-stored or incipient fault
Images match, if the match is successful, is passed the coordinate position of circuit image and correspondence thereof by wireless communicator 12
Transport to GCU 2.Wherein, images match can be in the way of using similarity mode, and similarity reaches
More than 80% i.e. thinks to break down or incipient fault in position corresponding to this circuit image, and is passed by this circuit image
Transport to GCU 2.
The aerial line inspection tour system of the present embodiment uses the mode that unmanned plane 1 and GCU 2 combine,
GCU 2 controls unmanned plane 1 and flies by given line, and receives the event that unmanned plane 1 collection is returned
Barrier image, incipient fault image and coordinate thereof, thus it is accurately positioned fault or incipient fault generation position.And
And determine whether that the work of fault and incipient fault is performed by the airborne computer 13 of unmanned plane 1, it is not necessary to people
Work checks each frame circuit image before GCU 2 one by one, significantly reduces cost of labor.
In the present embodiment, image acquisition device 11 determines the frequency of image acquisition according to flight speed and field range
Rate so that the circuit image of all collections is stitched together and can constitute the image of omnidistance circuit.As in figure 2 it is shown,
Field range is d, and after flying distance s, field range just covers another section of circuit, s/v=t, image acquisition
Device 11 t interval time gathers a width circuit image, and wherein v is flight speed, in order to ensure all collections
Circuit image is stitched together and can constitute the image of omnidistance circuit, and s is less than or equal to d so that adjacent twice collection
Circuit image has one section of circuit overlap.Wherein interval t gathers a width circuit image can be t bat interval time
Taking the photograph a photo, it is also possible to be high-definition camera, interval time, t extracted a two field picture.
In the present embodiment, airborne computer 13 is additionally operable to obtain unmanned plane 1 and aerial line from image acquisition device 11
Real-time distance, and keep real-time distance more than electrical shock safety distance.Specifically, the taking the photograph of image acquisition device 11
Shadow or the focus process essence taken pictures are exactly the process of range finding, can measure between aerial line and unmanned plane 1
Distance, when airborne computer 13 is asked, this distance is sent to airborne computer 13.Electrical shock safety distance just like
Lower standard: not less than 5m during voltage 500KV under air normal humidity (40%), during voltage 220KV
Not less than 3m, not less than 1.5m during voltage 110KV.
Airborne computer 13 is provided with a preset distance more than above-mentioned electrical shock safety distance, to control unmanned plane
1 is remained above this preset distance with aerial line, so will not cause unmanned plane at certain because of the fluctuating of aerial line at a moment
The distance with aerial line of 1 is less than electrical shock safety distance, thus avoids unmanned plane 1 Danger Electric shock risk.
Due to weather, such as: sleety weather, air humidity is relatively big, and air is easier to puncture, therefore
GCU 2 is used for the weather condition of real-time query overhead transmission line region completely, and according to air
The current electrical shock safety distance that humidity calculates, and by the electrical shock safety distance of calculating by wireless communicator 12
Transmission is to airborne computer 13.Electrical shock safety distance increases with the increase of air humidity, and concrete calculation can
Identical percentage ratio is increased, such as: humidity increases to 60% from 40% with the percentage ratio that increases by humidity,
Add 20%, then current electrical shock safety distance the most at least increases the electrical shock safety distance under standard humidity
20%.
In the present embodiment, GCU 2 for obtaining the seat of each built on stilts transmission tower according to aerial line map
Mark, and be arranged in order to form flight path by predetermined starting point and terminating point.Unmanned plane 1 aloft flies
Straight line, the aerial line between 2 is also straight line, so can guarantee that unmanned plane 1 can fly along overhead transmission line.
In the present embodiment, GCU 2 is for sending to airborne computer 13 by wireless communicator 12
Fixed point acquisition instructions, airborne computer 13 controls fault picture or the incipient fault image that unmanned plane 1 flies to specify
Corresponding coordinate points, GCU 2 controls unmanned plane 1 in real time and flies, and controls image acquisition device 11
Adjusting focal length is to shoot detail pictures.Image acquisition device 11 adjusting focal length is controlled especially by airborne computer 13,
So can obtain fault picture or the detail of incipient fault image, in order to manually make the most precisely
Judgement.
In the present embodiment, image acquisition device 11 includes: infrared camera or thermal camera, can clap at night
Take the photograph.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all the present invention's
Within spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
