Study on Signals Processing in State Detection of Tunnel Excavation Equipment's Cutter Head

Abstract:

In the period of real time mechanical analysis and life style detection to the excavation tunnel equipment's cutter head, it is a necessity for the signals sensed by detection unit to be pretreatment processed. It closely concerns with the accuracy and validity of whole mechanical analysis results. By analyzing the features of all possible interference, this paper gives a study on signals initial processing applying method of digital filter and blind signal extraction. Simulation results show that the proposed scheme is effective enough to the mechanical analysis task.
