Abstract
An intelligent optical fiber tactile sounding system and a method thereof, and belongs to the field of intelligent optical fiber sensing. The system includes a flexible optical fiber tactile sensing array, a photoelectric detection system, an intelligent pressure analysis software and an acoustic emission system; a small-scale distributed tactile sensing array is constructed by embedding a fiber-core mismatched optical fiber interferometric sensor into a flexible substrate material and performing sensing region division for an asymmetrical structure with an optical fiber structure as a delimiting line; a tactile sensor transmits tactile signals to the photoelectric detection system in the form of optical signals, the photoelectric detection system inputs these pressure signals into the intelligent pressure analysis software to determine a region and a size of a tactile source, and then sends an instruction to the acoustic emission system to enable the acoustic emission system to emit different sounds.
