Oil and natural gas pipeline inspection application

Leakage of oil and natural gas pipelines may cause serious accidents such as fire and explosion, posing great threats to the surrounding environment and personnel. The laser methane detector carried by the drone can be used to monitor whether there is a leak in the pipeline along the line, find and deal with the leak point in time, and avoid explosion and environmental pollution.

Flying over the complex terrain and environment, the pipeline line is comprehensively inspected, which ensures the comprehensiveness and accuracy of detection while increasing the scope of pipeline safety monitoring. Leakage monitoring can be achieved without entering hazardous areas, ensuring the safety of workers. Automation, remote control, save labor costs, improve inspection efficiency.

Application advantage

1. Non-contact detection: The laser methane telemeter adopts non-contact detection technology to avoid the safety hazards of traditional detection methods.

2. Real-time monitoring and remote control: Through real-time data transmission and remote monitoring system, to achieve real-time monitoring and early warning of gas leakage, improve the level of safety protection.

3. High precision and high sensitivity: It has the characteristics of high precision and high sensitivity, and can accurately detect trace methane leakage.

4. Suitable for complex environment: the drone laser methane telemeter can detect gas in a variety of complex environments.

5. Reduce labor costs: reduce the need for manual inspection and reduce labor costs.

6. Data traceability and analysis: Statistics and analysis are carried out on the data collected during the detection process to provide data support for safety management and decision-making.

Product composition

1- Laser methane telemeter LC30 Pro

Compared with the traditional electrochemical sensor detection method, the laser methane telemeter can realize non-contact measurement and quickly find the trace methane gas in the air. The maximum detection distance can reach 150 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 almost no maintenance and calibration of field measurements. Support the collaboration of DJI H20 series cameras to take high-definition visible and infrared photos at the location of recording methane concentration outliers.

The laser transmitting and receiving module is integrated inside the probe, and the receiving unit inside the probe contains the signal receiving circuit, the amplifying circuit, and the processing circuit. The central processor uses dual processors, one is a DSP processor for floating point operation, which can accurately and high-speed test the gas concentration, and the other processor is used for the functional control of the entire system, state detection, communication and so on.

The measurement laser is emitted after the collimator is twice concentrated to ensure that the diameter of the spot is less than 20cm outside 150M, and ensure that the light signal sent is strong enough to reduce the interference of sunlight on the received light signal and improve the signal-to-noise ratio.

The outer part of the probe is composed of a three-axis head, a measuring laser hole, an indication laser hole and a receiving window. The specific position is shown in the figure below

2- Software monitoring platform

The ground station software is used for route planning, which can easily realize middle and long distance pipeline inspection. During the inspection process, the current inspection status can be viewed in real time. In case of leakage, the system will automatically alarm and record data to generate inspection reports.

1. Home Page

As shown in the following figure, the main page is divided into three areas: model display, device identification, and login account.

Model display: When the remote control is connected to the drone, the corresponding model picture can be displayed in this area.

Device identification: When the methane device or DJI H20 series camera is connected to the aircraft, this area can display the identified device. Due to the slow startup speed of DJI SDK, the device recognition is slightly delayed, please wait patiently for the device recognition to appear.

Login area: Only after entering the correct account, you can access the subsequent page of the app. You can change the password, exit, and change the login account in the account operation. The interface after successful login is shown in the following figure.

2. Operate the page

The laser methane app software is developed based on DJI MSDK5.5, and the operation page is mainly composed of sdk controls, camera display, map display and function buttons as shown in the following figure.

Product advantage

1. High integration, small size, light weight.

2. Advanced TDLAS sensor technology, high sensitivity, high measurement accuracy, low detection limit, fast response speed, stable performance.
