Unmanned aerial vehicle inspection device and method for fuel gas pipeline

Abstract

The invention discloses an unmanned aerial vehicle inspection device and method for a fuel gas pipeline, relates to the field of fuel gas pipelines, and aims to solve the problems of low efficiency, difficulty in realizing inspection, high cost and susceptibility to weather environment existing in an existing natural gas pipeline inspection method. The method comprises the following steps that: aflight control module sends a control command to an unmanned aerial vehicle module, and a multi-rotor unmanned aerial vehicle flies according to the control command; a video recording module transmitsa collected digital image signal to a data receiving module through a wireless image transmission module, and transmits the collected digital image signal to an image processing module and the flightcontrol module; the image processing module splices and fuses received images, and transmits the processed images to an image analyzing module, a display module and the flight control module throughdata buses; the image analyzing module analyzes suspectable accident points, annotates the suspectable accident points on the images, broadcasts the confirmed accident points through an alarm module,and transmits the processed images to the display module for displaying; and the flight control module transmits the received image data to a data service center.

Description

Technical field [0001] The invention relates to the technical field of gas pipeline inspection, in particular to a gas pipeline drone inspection device and inspection method. Background technique [0002] As the cleanest energy source among fossil fuels, natural gas also has the advantages of high heat and energy efficiency, and is regarded as the most promising emerging high-efficiency energy. Pipeline transmission has become the preferred method of natural gas transportation due to its advantages such as low cost, safety and airtightness, large transportation volume, guaranteed quality, and easy control and management. However, natural gas is flammable and explosive. Once a pipeline leakage accident occurs, it may cause a series of disasters such as explosion, fire, poisoning, and environmental pollution. If it occurs in a residential area, it will cause more serious harm. The main reasons for leakage of natural gas pipelines include external force damage, corrosion and aging ...
