Telemetry device with camera function, drone and inspection method for gas leakage

Abstract

The invention discloses a telemetering device with a camera shooting function, an unmanned aerial vehicle and a gas leakage inspection method. The inspection method is carried out through the unmannedaerial vehicle, the unmanned aerial vehicle is provided with the telemetering device with the camera shooting function, wherein the camera shooting device of the telemetering device with the camera shooting function is installed on a telemetering instrument, an image center of an image information shot by the camera shooting device is kept the same as a detection center of a gas concentration information of the telemetering instrument, so that the inspection method can obtain an area to be inspected, the unmanned aerial vehicle is controlled to fly in the area to be inspected to obtain an inspection information of the telemetering device with the camera shooting function, the gas leakage is determined according to the gas concentration information, a gas leakage position is preliminarilydetermined according to a pose and position coordinates of the unmanned aerial vehicle and a pose information of a cloud deck, the position of the gas leakage is further determined by combining the image information in the same direction as the gas concentration information recorded by the capture camera shooting device, so that positioning accuracy of the leakage position is improved while the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gas leakage inspection, in particular to a telemetry device with a camera function, an unmanned aerial vehicle, and a gas leakage inspection method that can improve inspection accuracy. Background technique [0002] At present, the maintenance work of gas companies on pipelines is to use geographic information system and hand-held terminals to conduct manual inspections, and the second is to use vehicle-mounted detectors to conduct inspections. Both methods require manual visits to the site. Due to the wide distribution of natural gas pipelines, As a result, the inspection workload is heavy, the inspection data is scattered, and the pipeline is generally in good working condition, and the inspection personnel are very easy to relax their vigilance, resulting in leakage. [0003] The unmanned aircraft is referred to as "UAV" for short, and the English abbreviation is "UAV". It is an unmanned aircraft contr...
