Description

TECHNICAL FIELD [0001] The present invention relates to a method and a system for arraying a wire using a drone,

The present invention relates to a wire guiding method using a drone.

Conventionally, as a cabling method for crossover or replacement of a power distribution line and a communication line, there is a method in which a ground worker places a replacement cable on a ground and a column on each pole and communication pole in a line work section, (rope), the rope is pulled up by the column operator and then fixed on the insulator on the wire.

Such a conventional method requires workers to be placed on the ground and the column respectively in units of electric poles, and the above-mentioned operation must be repeated for each of the power distribution lines and communication lines installed in the electric pole, It is required to pull all the work to the main line and to pull the power line which is installed between Jeonju (telecommunication) and Jeonju (telecommunication) with a great force so as to maintain a tense state. Therefore, There was a problem that the safety and the safety were very weak.

In order to solve such problems, a multi-functional approach of power technology 9 has been proposed. Multifunctional elevated line method of Power New Technology No. 9 relates to a device and a method which can simultaneously (line and long line) and simultaneously change 2 ~ 4 lines of power distribution line (communication cable) by using a power line during power distribution.

However, even in the case of using the multifunctional approach method of Power New Technology No. 9, the problem is that the workers must spread the tow rope to the floor, and then the workers must lift the rope up to the pole and mount the rope on the pole. There is still this long problem.

KR10-1443255B1

In the present invention, workers are required to reduce the labor of laying ropes on the floor and lifting them up to the pole in order to cut or replace wires to distribution lines and communication lines, and also to reduce the preparation rope lead time required to lead extra high voltage wires. In addition, we want to solve the problem of safety accidents caused by workers installing ropes.
