Abstract:

The seismic exploration chip set from Cirrus Logic Company is chosen as the core component of acquisition system of the coalmine underground seismometer.The characteristic,structure and operating principle of Cirrus Logic chip set are introduced,and the hardware circuit and control software are designed for its use in coalmine seismometers.Experiment results show that the designed seismometer can meet the need of intrinsic safety,small size,low power consumption,high speed,high accuracy and portability.

Key words: intrinsic safety,seismometer,Cirrus Logic,embedded technology
