Application of MYUAV Methane Leak Inspection in Industrial Parks

Industrial park methane leakage monitoring background

As drone technology continues to develop, its applications in industrial fields are becoming more and more widespread. As an emerging detection method, drone methane leakage inspection has the advantages of fast speed, high efficiency, and strong safety, which provides a strong guarantee for the safe production of industrial parks.

Methane is a common flammable and explosive gas, and the risk of leakage in park pipelines and other facilities cannot be ignored. Traditional methane leakage detection methods mainly rely on manual inspections, which have problems such as limited coverage, slow detection speed, and high safety risks. Therefore, how to improve the efficiency and safety of methane leak detection has become an important challenge facing the industry. Through the methane leakage detection equipment carried by the drone, the gas concentration along the pipeline can be monitored in real time, hidden leakage hazards can be discovered, and the safe operation of the pipeline can be ensured.

LC30 Pro(5G) Laser Methane Telemeter

Compared with traditional electrochemical sensor detection methods, the LC30 Pro (5G) laser methane remote meter can achieve non-contact measurement and quickly detect trace amounts of methane gas in the air. The longest detection distance is up to 220 meters, and it is not affected by environmental factors such as temperature, humidity, and pressure, and has very high stability. It has the characteristics of high sensitivity, high measurement accuracy, low detection limit, fast response speed and requires almost no maintenance and calibration of on-site measurements.

System composition

The L30Pro (5G version) laser methane detector can currently be mounted on DJI M300RTK and M350RTK drones. The methane concentration data collected by the sensor can be transmitted to the remote control APP through various transmission methods such as 5G module and DJI SDK. The web page is displayed.

Detection principle

The TDLAS principle of tunable semiconductor laser absorption spectroscopy is used. Based on the absorption properties of the methane molecular structure for light of a specific wavelength, when a laser beam passes through a methane air mass, the degree of absorption of light by the absorption spectrum lines of the methane molecules is analyzed to calculate the air mass. Methane concentration.

Software function

1.Web page

Carry out unified monitoring and management of methane data. It has the functions of calling map, 3D/2D/plan view switching, 3D flight trajectory display, color block value display, real-time data display, mark points and measurements, abnormal area statistics, quick positioning, query history, and report export.

2.APP side

During the inspection process, the drone status and methane measurement data can be viewed in real time. In the event of a pipeline leak, the terminal device will automatically alarm and record the data (time, coordinates, leakage concentration, on-site photos) so that an inspection report can be automatically generated later. Open the Android desktop icon and enter the LaserMethane app login interface.

Media library view

Pictures and videos are displayed in categories, and file names are displayed in forward and backward order. Each time you enter the media library, the files in the camera will be automatically updated.

Route function

The route editing interface can edit and modify the route. After the route is uploaded, the drone can perform automatic flight inspection and wait for updates.

Real-time curve viewing

Check the curve value in real time and monitor the maximum concentration value and real-time concentration value that appear in this methane detection. Data can be output 50 times per second. In order to facilitate the observation of instantaneous concentration values, it is recommended to turn on the real-time curve function during the flight of the drone.

equipment control

Click the "PSDK" button to perform menu settings and achieve precise control of the PTZ.

history record

During the route flight, once a methane gas leak exceeding the threshold is detected, the drone will automatically take photos and record relevant information such as the current concentration value, number of abnormal data, longitude and latitude coordinates. You can switch to view the history records of different times by clicking on the time name, or you can pop up the operation box by long pressing to upload data to the server and delete data.
