Special structures for coherent FBG group and fiber MZI
sensors are designed. For weak signals or strongly interferenced
signals, winding method, flat layout method, special coated fiber method
or spring separation method, solid separation method are proposed, and
the recognition ability for object signals is improved. The physical
features of the object signals are extracted from various aspects by the
parameters analysis such as maximum amplitude, RMS, ringing count,
pulse count, event count and duration, by the waveform transform
analysis such as Fourier analysis, AR spectrum analysis and
joint-time-frequency analysis, and by statistic analysis of the
parameters analysis results or waveform transform analysis results. And
the features of different object signals are extracted when the optical
fiber sensing systems are applied for railway location, axel counter,
fence destruction monitoring and pipe destruction monitoring. Auto-recognition
of the railway location signals with coherent FBG sensing system is
realized by a linear discrimination function based on Fisher criterion.
And auto-recognition of the fence destruction signals with a
MZI sensing system demodulated by a 3×3 coupler is realized by a LMBP
neural network.
