▎ 摘　　要

NOVELTY - The system has a fiber optic sensor is arranged on the outside of the gas pipeline. The output end of the optical fiber sensor is connected to the input end of the monitoring host. The output end of the monitoring host is connected to the input end of the terminal. The output terminal of the monitoring host is also connected to the input terminal of the alarm module. The input terminal of the display screen is connected with the output terminal of the monitoring host. USE - Portable optical fiber sound wave monitoring system. ADVANTAGE - The optical fiber sound wave monitoring system adopts the graphene advantages of small volume, light weight and so on, it has good application value in monitoring and security, at the same time, facing the complex signal, using linear instantaneous hybrid model, analyzing and identifying the signal, parameter measurement, accurately extracting the target signal when necessary, realizing good noise-reducing and impurity-removing effect, and the detection effect is more rapid and obvious. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of portable optical fiber sound wave monitoring system. (Drawing includes non-English language text).
