Laser gas monitoring system
In the extraction and transportation of energy sources such as oil and natural gas, methane leakage mayoccur due to the aging and corrosion of equipment or pipelines, as well as construction factors. This notonly threatens the lives and safety of on-site personnel but also causes serious enyironmental pollutionBeing able to locate the source of leakage in real time and accurately and trigger early warnings will be themost solid safety guarantee for the lives of workers and key assets.The Tongxin laser gas monitoring system integrates gas detection, video surveillance, and high-precisionPTZ, enabling all-weather, all-round, fully automatic, and long-distance non-contact methane leakagemonitoring,The maximum detection distance can reach 160 meters,significantly reducing the risk of large-scale production safety accidents. With the active defense mechanismof "early detection and early handling", this system has become a key defense line for preventing industrialproduction safety accidents and an efficient tool for safeguarding the lives and property of people aroundthe world. it is also a key cornerstone driving global sustainable development and climate governanceplaying an indispensable strategic role in promoting the realization of global environmental protection andsustainable development goals.
Technical Principle
————————
Lambert-Beer law
The absorption rate of light when passing through a gas is directly proportional to the gas concentration and the optical path length.
TDLAS
By adjusting the current and temperature of the laser, the absorption spectral lines of the target gas molecules are scanned. The laser spectrum after passing through the gas is analyzed to calculate the gas concentration. This technology has the characteristics of high selectivity and high resolution, and is not affected by other gases. It is suitable for the concentration measurement of various gases.
Safe and reliable
The housing of the camera is made of 316L stainless steel and formed by welding, which is structurally robust. The sealing strip of the end cover is made of high-quality NBR, featuring excellent waterproof performance, long service life and resistance to aging.
Multispectral monitoring
The laser methane sensor and the camera work simultaneously, providing real-time on-site images and methane concentration data. The camera uses a starlight-level high-definition core, which can still offer high-quality color images under low illumination. This enables users to observe the location of methane leakage in the fastest and most intuitive way.
Wide range，various occasions
High-precision PTZ, with a product protection level reaching IP66/IP68, enables all-round, all-time, all weather, long-distance, and large area monitoring, meeting the usage requirements of various scenarios.
High-precision area coverage
High-precision electrically controlled PTZ, with an accurate angle calculation module in conjunction with a long-life closed-loop servo motor, enables continuous cruise scanning of prone to leakage areas.
High independence
The explosion-proof gas monitoring camera, explosion-proof control box and explosion-proof junction box at the front end can operate independently to scan the area, monitor the methane concentration and issue an alarm through the sound and light alarm device even when disconnected from the back end software.
Quick response
It has high selectivity and sensitivity towards methane gas, and is minimally affected by other gases, water vapor, and dust. It has a wide temperature range, high sensitivity, and high response speed. In case of methane leakage, it immediately transmits the alarm signal. Truly achieving real-time supervision of production safety and environmental safety.
