Embodiment
A kind of electric line foreign matter intrusion detection intelligent early-warning method, electric line foreign matter intrusion detection scene photo such as Fig. 1
It is shown, including shaft tower 1, transmission line of electricity 2, insulator 3 and monitoring all-in-one 4.Monitoring all-in-one 4 uses existing product, such as
The vertical ST-NTMS-EICD of gold three, fierce look peace Q2A-CAM-4G.Basic structure is the combination of solar panel and camera system.
Monitoring all-in-one 4 is positioned over correct position on shaft tower 1, is generated electricity and is powered for video camera by solar panel, video camera pair
Transmission line of electricity 2 and its near zone are monitored, and are able to detect that the dangerous informations such as the foreign matter of invasion transmission line of electricity 2, and pass through
Monitored picture is transferred to background monitor by the mode of wireless telecommunications in real time.
Electric line foreign matter intrusion detection monitor picture simulation drawing as shown in Fig. 2 the screen 5 including background monitor,
It is transmission line of electricity A phase lines 6, transmission line of electricity B phase lines 7, transmission line of electricity C phase lines 8, invasion foreign matter 9, yellow prewarning area 10, orange pre-
Police region domain 11, red early warning region 12.
The screen 5 of background monitor is modeled into a plane right-angle coordinate, and is divided into several square tiles,
Each fritter to that should have a coordinate (Xn, Yn), for determine transmission line of electricity plane rectangular coordinates equation Y=Y (X) and
Invade the coordinate (X of foreign matter0,Y0).When whether system monitoring exceeds safely to the size for when having foreign body intrusion, first determining whether foreign matter
Value.When size exceeds safety value, corresponding early warning action is performed；Otherwise, without early warning.When foreign matter size exceedes safety value
When, foreign matter is further calculated from a distance from transmission line of electricity 2 and making corresponding alarm mode or not early warning.When distance is less than
At 3 meters, start red early warning；When distance is 3-5 meters, start orange early warning；When distance is within 5-7 meters, start yellow early warning；
When distance is more than 7 meters, without early warning.According to《People's Republic of China's professional standard electrical safe working order》Regulation, each electricity
The transmission line of electricity of pressure grade has respective safe distance, and such as 220KV transmission line safeties distance is 3 meters, 330KV transmission lines of electricity
Safe distance is 4 meters, and 500KV transmission line safeties distance is 5 meters.Certainly, the position nearer apart from transmission line of electricity distance is dangerous
Property is also higher.3 meters, 5 meters and 7 meters are set in this invention to be intended merely to explain this method for early warning as warning limit, in reality
In the engineering of border, the warning limit tallied with the actual situation should be set out according to the voltage class and periphery situation of transmission line of electricity.
A kind of electric line foreign matter intrusion detection intelligent early-warning method of the present invention, can be transmission line of electricity 2 and invasion foreign matter 9
Represented with the form of coordinate, and intelligent prediction policy is made from the horizontal range of transmission line of electricity 2 according to invasion foreign matter 9.
The present invention is to calculate to invade the size of foreign matter and its spacing with transmission line of electricity in actual field using math equation
From method.
Concrete operating principle is as follows：
(1), the screen 5 of background monitor is modeled in the plane right-angle coordinate with several grids, monitored picture
All positions can be represented with equation in coordinates and point.So, transmission line of electricity center is that can be expressed as a Y on X
One- place 2-th Order function：Y (X)=AX2+ BX+C, invasion foreign matter 9 can be expressed as (X0,Y0)。
Wherein：X represents abscissa, and Y represents ordinate, and A, B, C are coefficients.
(2), when having detected foreign body intrusion, the size first to foreign matter is identified, and method is as follows：
A, each point coordinates (X for determining foreign matter boundary1, Y1)、(X2, Y2)……(X2, Yn)。
B, therefrom filter out X-axis, the maximum of Y-axis, minimum value Xmax、Xmin、YmaxAnd Ymin, and its corresponding four points
(Xmax, Yn1)、(Xmin, Yn2)、(Xn1, Ymax) and (Xn2, Ymin)。
C, respectively calculating (Xmax, Yn1) and (Xmin, Yn2) the distance between 2 points
(Xn1, Ymax) and (Xn2, Ymin) the distance between 2 points
D, compare dxAnd dyBoth sizes, take higher value as the approximation of foreign matter maximum gauge.
(3), judge whether foreign matter can cause danger to transmission line of electricity.Harm of the foreign matter to transmission line of electricity most serious is typically
The short circuit that foreign matter bridges wire and caused, according to the spacing of the two-phase of transmission line of electricity 2, is set as 1 meter in the present invention, can set foreign matter
Safe diameter be 0.5 meter.Set when foreign matter maximum gauge is less than 0.5 meter, danger will not be caused to transmission line of electricity 2, therefore
Without early warning；Conversely, suitable early warning scheme should be further determined that.Due in foreign matter in the air flotation process state have it is not true
Qualitative, the maximum gauge calculated according to the state at a certain moment is possible to not be the actual maximum of foreign matter, therefore should set
Put repetition monitoring calculation program：, should when ought monitor foreign matter, and calculate the maximum gauge for obtaining quarter in some time less than 0.5 meter
The delay 0.1 second simultaneously continues to calculate the maximum gauge of subsequent time foreign matter；It is maximum straight that once a certain moment calculates obtained foreign matter
Footpath should just further determine that early warning scheme more than 0.5 meter, otherwise constantly should be delayed and calculate, until foreign matter leaves monitoring sight
Scope.
(4), when the maximum gauge for calculating foreign matter is more than 0.5 meter, a progress is answered to calculate foreign matter from transmission line of electricity 2
Minimum distance.It can be obtained according to point to the range formula of straight line, foreign matter is from being point (X with a distance from transmission line of electricity0,Y0) arrive straight line Y (X)
=AX2+ BX+C distance is：
(5), the beeline according to foreign matter from transmission line of electricity, it is determined that appropriate early warning scheme or not early warning.
A, work as D<At 3 meters, red early warning is triggered；
B, when 3<D<At 5 meters, orange early warning is triggered；
C, when 5<D<At 7 meters, yellow early warning is triggered；
D, work as D>At 7 meters, without early warning.
Above-described prediction policy is that the extent of injury of transmission line of electricity is adapted with invasion foreign matter, different early warning
Information can help duty personnel to make correct judgement and counter-measure.When foreign matter enters monitored picture but without labeled
When, duty personnel need not just check the monitored picture；Yellow is marked as successively when foreign matter, it is orange and red when, duty personnel
Attention degree should accordingly be improved；On the other hand, the foreign matter for small volume without endangering transmission line of electricity, system can be with
Automatic shield information, it is to avoid frequent starting early warning or wrong report.
