Method for achieving unmanned aerial vehicle autonomous inspection of power transmission line by intelligent hangar

Abstract

A method for achieving unmanned aerial vehicle autonomous inspection of a power transmission line by intelligent hangar comprises the steps of determining a set intelligent hangar number range according to a performance parameter of an unmanned aerial vehicle for inspection and time for inspection each time and according to total number of pole towers needed to be inspected and positions of otherunmanned aerial vehicles and pole towers; calculating a hangar position under each condition in training rotation with regard to the number of each type of different hangars so that the sum of distance from each pole tower to the nearest hangar position is shortest and optimal hangar position is obtained; and calculating a setting crusing line according to the hangar number and position. By interconnection of the unmanned aerial vehicle intelligent hangars, the position of the intelligent hangar is designed and calculated, the unmanned aerial vehicle crusing line is designed, full-autonomous inspection of the unmanned aerial vehicle is achieved, the hands of an inspector are free, the inspection efficiency is greatly improved, automatic and intelligent operation is achieved, the inspectionprocess is simplified, and the inspection of the power transmission line is promoted to be further developed towards a full-intelligent direction.

Description

technical field [0001] The invention relates to the technical field of intelligent patrol inspection of power transmission lines, in particular to a method for realizing fully autonomous patrol inspection of drones by using a drone smart hangar. Background technique [0002] At present, the most common transmission line inspection method in my country is still manual inspection. The inspectors inspect the power lines through visual inspection with the naked eye or by personally climbing the tower. The labor intensity is high, the working conditions are difficult, and the labor efficiency is low. And difficult to manage. The scale of national grid equipment will continue to develop rapidly. From 2016 to 2002, 401,000 kilometers of new 110 kV and above lines will be added across the country. The contradiction between the increase in operation and maintenance workload and the shortage of personnel has become increasingly prominent. Relying solely on manual inspections for power ...

Problems solved by technology

[0005] However, the existing UAV transmission line inspection process must be equipped with at least 2 line inspection personnel to follow. When the UAV battery life is insufficient, they have to recycle the UAV and replace the battery pack before they can Continue drone inspections

This not only greatly increases the consumption of manpower and material resources, but also fails to realize the full autonomous inspection of transmission lines proposed by the State Grid in the future.

[0006] That is to say, there are the following problems in the current inspection of drones: (1) The autonomy and intelligence level of drone operations need to be further improved

The degree of autonomy of drone inspection operations is low and does not meet the practical requirements

(2) The cruising range of drones is short

UAV inspection must be equipped with at least 2 inspection personnel. When the power of the UAV is not enough, the UAV should be recovered in time and the battery replaced, and then continue to complete the inspection operation, which limits the UAV inspection to a certain extent. The development of detection technology
