Design of Automatic Analysis System for Microtremor Characteristic Waveform

The microtremor carries information closely related to the shallow crust media, and we can take advantage of the microtremor to do site evaluation and nondestructive testing, etc. We design a automatic analysis system of the microtremor characteristic waveform, for the convenience of field data scrapers and waveform characteristic analysis in the field microtremor exploration experiment. The system uses mathematical calculation software Matlab to write the corresponding program for microtremor recording data intime domain and frequency domain analysis, and uses object-oriented C# programming language design software interface. The system can realize the signal characteristic waveform quantization processing, characteristic waveform automatic picking, data file and results graphics automatically generating. The application results show that the automatic analysis system of the microtremor characteristic waveform can analyze the mierotremor, which can meet the actual needs of users.
