Main Benefits

Efficiency

Outperforms foot search by 5x times

Accuracy

Detected leaks are referenced to GPS coordinates (high fidelity RTK GPS is also supported)

Increased safety

Applicable at unsafe and hazardous environments without compromising the safety of staff or equipment

Automation

Fully automated and repeatable surveys

Precision

Laser detector LMm is sensitive only to methane, so no false readings of other gases are possible

Reporting

Fully automated reporting

How it works

> Mount the methane-leak-detection kit onto DJI M600 drone

> Plan survey mission with UgCS

> Receive data during flight

> Generate a report with detected methane leak locations
 

The system consists of the M600 integrated with laser methane detector LMm by PERGAM. The full integration is ensured by adding the onboard UgCS data logger to the system.

Application Notes

Case Studies

Methane leak detection

Customer: Conexus Baltic Grid, JSC

Goal: Locate methane leaks.

Technology: integrated Laser Methane detector by PERGAM with a drone equipped with a laser altimeter.

Flight control: UgCS with True Terrain Following mode.

Result: Methane leaks can be located during the drone's inspection flight. Methane level data is being logged with precise GPS coordinates of drone's autopilot.

The Integrated System

Laser Methane Detector

Laser Methane Detector by PERGAM is sensitive only to methane, so no false readings of other gases are possible. It is a class 3R eye-safe laser.

The concept is based on Infrared Absorption Spectroscopy. Laser light in the spectral range of 1,65 μm is emitted. The laser light is reflected in the background and captured back in the instrument. The outgoing and incoming signals are compared with a built-in reference cell. If methane gas is present along the laser path, the laser light is partially absorbed. An algorithm calculates the gas concentration in ppm×m (parts per million multiplied by meter). The value is instantly transferred to the remote control (RC) of the drone pilot and to UgCS software.

UgCS Data Logger

UgCS Data Logger is the key element that enables the full integration of the drone, laser methane detector, and ground control software UgCS. The onboard UgCS Data Logger, designed by SPH Engineering, saves the gas detector’s data in .txt format and transfers them instantly to the remote control of the drone pilot and to the desktop software UgCS. This allows operators to detect leaks in real time and ensure faster response time.

The UgCS Data Logger enables also to add a laser altimeter to enable the flight in True Terrain Following mode, which enables the drone (UAV) to accurately follow the terrain during the flight, based on data received from the laser altimeter. True Terrain Following enables the drone to fly at constant AGL altitude without a need to import precise Digital Elevation Model (DEM) height-map into UgCS.

The Drone

Currently, the UgCS Data Logger is compatible with DJI M600 and M600 Pro. It is a durable system which offers extended flight time (up to 25 minutes) and a 5-kilometre-long range of data transmission.

UgCS

Smooth operation is ensured by UgCS software, developed by SPH Engineering in Riga, Latvia. Besides supporting most industrial drones on the market, it offers several productivity-enhancing innovations: automatic Photogrammetry, Facade scan, and Search pattern tools. Most importantly for methane detection, UgCS software allows for the drone to be flown at a constant height, even over rough and mountainous areas, as its 3D maps and terrain-following mode can cope with any kind of landscape. UgCS's drone mission planning software also provides tools for the easy creation and calculation of flight paths, and for the interpretation of acquired data in a user-friendly manner.
