▎ 摘  要

NOVELTY - The system has an upper layer polyethylene glycol terephthalate film (3) arranged on an upper surface of a graphene film (2). A surface of a graphene film (2) is provided with two copper electrodes (21) that are arranged together in parallel. An optical signal output end of a fiber Bragg grating sensor strip (1) is connected with an optical signal input end of an optical fiber grating sensing demodulator (6) through an optical jumper. The copper electrodes are connected with anode and cathode ends of a composite film input power supply (7). USE - Optical fiber grating and graphene film based icing monitoring and ice melting integrated system. ADVANTAGE - The system can synchronously monitor icing and ice melting process in real time with flexible allocation, and has high accuracy and high efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an optical fiber grating and graphene film based icing monitoring and ice melting integrated system.
