10. 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.

18. The comparative investigation of the characteristics of deformation and AE were conducted and the results are presented as followed: 1. The characteristics of rock AE are correlated to the strength, joints, cracks, and the size and hardness of crystalline grain. 2. The sequence of AE can be divided into four phases: beginning phase, tempestuousness phase, drop phase and dreariness phase. The loss and the duration of the phases are correlated to the rock character and flaws in the rock. 3. The AE rate characteristics are not almost concordant with the AE energy rate. 4. Besides the homogeneity, the strength of rock contributes the activity of AE. The higher the strength is, the lower the activity is. 5. There is a dreariness phase before the failure of most kinds of rock. 6. Whether the precursor is obvious is correlated to rock the character, and the precursor of AE rate is more apparent than the precursor of AE energy rate comparatively.
