Modeling the optimal parameters for a remote sensing device

Study of Wind Speed Effect on Laser Detection in Natural Gas Pipeline Leaking

“…Among them, laser technology is widely used by researchers because of its high sensitivity and quick response. In order to reduce the impact of various ground disturbances, Bushmeleva et al [9] proposed a computer model for detecting natural gas pipeline leakage by lidar, calculated the radar parameters and selected the optimal value, and make it applied to remote sensing aircraft. Li Zhengwen et al [10] put forward the airborne natural gas pipeline leak monitoring infrared laser radar technology, and employed the noise equivalent concentration theory to obtain good detection sensitivity, in order to eliminate the interference of external environment factors to some extent.…”

“…Yu Dianqiang et al [11] improved the existing electrochemical and infrared optical sensors and developed a tunnel CH 4 /H 2 S leakage laser detection instrument. Although laser technology can detect natural gas pipeline leakage [9][10][11] effectively, the pipeline leakage has a certain influence on the laser detection process, so it is pretty important to know the diffusion characteristics of natural gas pipeline leakage. Fu Jiqiang [12] numerically simulated steady and unsteady leakage process of overhead gas pipeline when natural gas pipeline are perforated, and analyzed the influence of the leakage flow rate and speed of gas diffusion law.…”
