Embodiment 1

[0028] This embodiment provides a gas leakage detection method, please refer to figure 1 , the gas leak detection method comprises the following steps:

[0029] Step S1: Control the UAV to fly along the set flight trajectory in the area to be measured, and detect the concentration of the gas to be measured at the point where the UAV flies;

[0030] Step S2: When the concentration of the gas to be measured at a certain point is detected, synchronously judge whether the detected concentration of the gas to be measured is greater than zero, if yes, go to step S3; if not, go back to step S1, and carry out Detection of the gas concentration value at the next position point; if no concentration value greater than zero is detected until the drone completes the flight of the set flight trajectory, it is determined that there is no gas leakage in the area to be measured;

[0031] Step S3: When the concentration value detected in step S2 is greater than zero, control the UAV to fly aro...

Abstract

The invention provides a gas leakage detection method and detection system, which relate to the technical field of gas detection and are used to solve the problem that the location of the gas leakage source cannot be detected in time in the prior art. Wherein the gas leakage detection method includes: controlling the unmanned aerial vehicle to fly along the set flight trajectory in the area to be measured, and detecting the concentration of the gas to be measured; synchronously judging whether the detected concentration value is greater than zero, and if so, controlling the unmanned aerial vehicle The man-machine flies around the point where the concentration value is greater than zero, detects the concentration of the gas to be measured around the point where the concentration value is greater than zero, finds the point with the largest concentration value, and takes the point with the largest concentration value as the point to be tested The leakage source of the gas; if not, return to the previous step, if no concentration value greater than zero is detected until the drone completes the flight of the entire set flight trajectory, then it is determined that there is no leakage of the gas to be measured in the area to be measured. The gas leakage detection method provided by the invention is used for gas leakage detection of gas equipment.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas leakage detection method and detection system. Background technique [0002] With the development and utilization of various resources, some gas resources are widely used in various fields, but because some of the gases are inherently dangerous, such as toxicity or flammability, once leaked, it is likely to cause accidents. For example, methane can be used as fuel in domestic and industrial production, but high concentrations of methane can suffocate people or cause explosions. Therefore, how to detect whether there is a gas leak and deal with it in time is particularly important. [0003] At present, one of the more common gas leakage detection methods is to install a gas concentration detection device and a positioning device on the UAV, and at the same time set a terminal control device on the ground for controlling the operation of the UAV. When detecting gas le...
