▎ 摘　　要

NOVELTY - The monitoring and response system has a microfluidic dielectrophoresis system, a reduced oxidation graphene sensor system, a XR-2206 function generator system, a 8051 microprocessor and an optical coupler system (25) that are connected together. USE - Hydrogen leakage monitoring and response system for a hydrogen mixing system for mixing hydrogen and natural gas. ADVANTAGE - The hydrogen leakage monitoring and response system ensures safe mixing of hydrogen and natural gas. The microfluidic dielectrophoresis system avoids forming of the graphene sheet aggregate. The system has enhanced sensor sensing characteristics removing the oxygen-containing group and defect contained in the oxidation. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a hydrogen leakage monitoring and response system diagram of hydrogen mixing system. 1First connecting plate 2Second connecting plate 13PLC control system 25Optical coupler system 29Processing terminal 31Hydrogen pipeline
