On-line inspection method for infrared temperature sensing device of unmanned aerial vehicle power equipment

Abstract

The invention relates to an on-line inspection method for an infrared temperature sensing device of unmanned aerial vehicle power equipment. An unmanned aerial vehicle is utilized to patrol and inspect power high-voltage equipment, when an infrared thermal imaging probe in a compound eye probe detects that the heating temperature of certain power high-pressure equipment reaches an overheating fault early warning value, the unmanned aerial vehicle gives an alarm to a remote control system and flies over a standard inspection temperature calibrator for temperature calibrating, if the calibratingerror is within an allowable negative deviation range, a control module gives an fault early warning of the overheated power high-pressure equipment, a thermal imaging image of the overheated fault equipment is displayed on a display screen, and a worker is reminded to take measures as soon as possible to eliminate faults. The on-line inspection method for the infrared temperature sensing deviceof the unmanned aerial vehicle power equipment has the advantages that temperature measurement detection can be automatically carried out on the power high-pressure equipment, and powerful guarantee is provided for the safe and economic operation of the power high-pressure equipment of transformer substations.

Description

technical field [0001] The invention relates to the field of power equipment operation and maintenance, in particular to an online inspection method for infrared temperature sensing devices of unmanned aerial vehicle power equipment. Background technique [0002] There are currently three ways to inspect the overheating fault of traditional electric high-voltage equipment: 1) Power off the high-voltage equipment, and do corresponding electrical tests such as DC resistance, leakage, insulation, and withstand voltage; 2) The staff carry infrared thermal imaging When the equipment goes to the substation or the ground of the high-voltage transmission line, manual temperature measurement and scanning are performed on the high-voltage equipment one by one and section by section; 3) UAV flight inspection with an infrared temperature measurement probe. [0003] The above three technical solutions all have different disadvantages. The first type: power failure is required; the secon...

Problems solved by technology

The first type: power failure is required; the second type: manual operation is required, the workload is large, the speed is slow, and the efficiency is low, and it is impossible to perform on-site calibration of the infrared temperature measurement equipment used; the third type: when the infrared temperature measurement Faults or quality problems of the equipment itself lead to inaccurate temperature measurement, and it is impossible to calibrate the temperature of the infrared temperature measurement equipment used on site, which may cause misjudgment, and changes in the terrain along the flight, such as temporary occurrences such as kites When there are obstacles such as balloons, branches growing on high slopes, bamboo branches, etc., or when dangerously close to electric high-voltage equipment, it cannot automatically avoid and fly away, which may cause serious personal and equipment safety accidents.
