Distributed Identical Grating Sensing System Oriented to Equipment Intelligent Sense in Cloud Manufacturing

Abstract : The intelligent sense of equipment is a key link in cloud manufacturing. Identical fiber Bragg gratings (FBG) have a flexible multiplexing number and are unaffected by the laser’s bandwidth. A distributed identical grating system oriented to cloud manufacturing equipment’s intelligent sense is developed by combining wavelength tunable laser and broadband laser source in this paper. The system collects the reflect spectroscopy to calculate the center wavelength of each FBG by Gaussian fitting. Some optimization is also done to the Gaussian fitting algorithm to increase the demodulation speed in this paper. In the system, 100 reflective FBGs of only 0.1 % reflection with the interval space of 5 m are connected to a long fiber. All the central wavelengths and positions of the FBGs can be measured. The results show that the linearity of the center wavelength with temperature is up to 99.8 % in range of −10 °C to 60 °C.
