It starts to work, the distance between concave-convex lens group camera lens and imaging screen variation delta u will be directly fed back to information centre's processing system
In system, u0With the as required image distance u of the sum of Δ u.
According to the variable for feeding back to information centre's processing system, pass through derivation formula
Corresponding laser focusing amount s at this time is calculated, and by information centre's processing system to Laser emission and autofocus system
Built-in motor send out instruction, so that it is adjusted focusing amount s at this time to corresponding value, to complete laser automatic focusing;Its
Middle F1For the natural photoimaging systems convexity focal length of lens, F2It is nature to take negative value, D for the natural photoimaging systems concave focal length of lens
Concave-convex lens distance in photoimaging systems, u are the image distance in nature photoimaging systems, f1For the concavees lens in laser focusing system
Focal length, f2For the focal length of convex lens in laser focusing system.
The laser emitter is using the adjustable laser emitter of luminous power of laser light source, the operator on ground
The case where member can be according to foreign bodies on transmission lines selects the optical power adjustment shelves of laser emitter on contact action plate in advance
Position;The beam collimator forms collimating optics unit, the laser for sending out laser emitter using at least two pieces of eyeglasses
Beam collimation, the control device of this part further include switching and being used for for adjusting the optical power adjustment of excitation-emission device luminous power
Indicate the luminous power indicator of luminous power size.At the same time, the cooling system is installed in the lower end of laser emitter, including
Cooling switch and temperature indicator two parts prevent laser emitter because of high frequency work for cooling to laser emitter
Make the high temperature generated and damages.
Above-mentioned obstacle recognition is identified using consistency profiles extraction contour of track, in the grid line being made of straight line
There are barriers, and the contour line of identification will be caused to generate mutation by Lu Zhongruo, sets the threshold value φ of mutation to know to barrier
Not, it is identified as barrier if mutation value is more than threshold value φ and draws a circle to approve the profile, if mutation value is skipped less than threshold value φ.It is above-mentioned
People, object identifying system be to be extracted to image information using consistency profiles, and be compared with information in database, identification exist
It whether there is natural person and birds within the scope of laser effect.
Consistency profiles above-mentioned it is characterized in that:Binary conversion treatment is carried out to the picture of shooting first, by the pixel on image
The gray value of point is set as 0 or 255, whole image is showed apparent black-white visual effect, then to the image of binaryzation
Be read out, carry out image scanning line by line, if image contains multiple black blocks, extract from left to right each color lump profile and only
Extract a profile.In order to improve recognition efficiency and speed, exterior contour information is only extracted, internal information is ignored, with
This reduces data processing amount.First profile point is defined and looked for profile point simultaneously, and from it, four adjacent up and down
Point starts recurrence and finds, until the point of entire profile is all searched out.The definition of the profile point, it is characterised in that if
There are one being white point in 8 consecutive points (upper and lower, left and right, upper left, lower-left, upper right, bottom right) of one stain, that is, it is considered
Profile point.
Above-mentioned identifying system be identified using OpenCV and it known others, object or barrier carry out with
Track, the emergency braking system are when the identifying system judges that there are natural person or birds within the scope of laser effect
When, emergency braking system will receive the power-off signal sent out from information centre's processing system, can quickly cut off Laser emission
The power supply of circuit switchs.The laser transmitting system only recognizes circuit when identifying system, and recognizes on circuit
There is a barrier, and unidentified emits laser to can just start LED laser pipe when people or birds.
It is above-mentioned a kind of the long-range barrier clearing device of molten electric transmission line hot-line to be cut based on laser, it is characterised in that:Supply unit
With control system, laser emitter, switch, cooling device are connected, and reliable power is provided for them.
