▎ 摘　　要

NOVELTY - The system has a measuring sensing module connected with a data processing module through a printed circuit board (PCB) board. The data processing modules and an upper computer system are connected with each other for wireless transmission. The measurement sensing module is provided with a first measuring sensor and a second measuring sensor. USE - Used as wireless monitoring system based on variable rigidity double-spring graphene displacement sensor. ADVANTAGE - The system can transfer the displacement of the tested structure to the high stretching graphene, and the graphene resistor generated by the graphene is converted into electric signal, at last, the data is displayed in the hand of the user through the wireless transmission protocol, realizing the monitoring of the displacement. The user can be patterned according to the actual requirement, graphene as to satisfy the different range and application scene. The sliding rail is set in the shell for limiting displacement, which can effectively avoid the inclination caused by uneven stress, destabilization and so on, improving the measuring precision. The graphene unit and the connecting unit are connected by a bolt, it can realize any change of the graphene unit, which is good for the mounting and dismounting of the technician. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a wireless monitoring method based on variable stiffness double-spring graphene displacement sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the wireless monitoring system based on variable rigidity double-spring graphene displacement sensor (Drawing includes non-English language text).
