This paper presents an innovative approach based on hardware and
software to develop a multichannel seismic monitoring and data
acquisition embedded system. The hardware was designed by using basic
electronic components and integrated circuits. It consists of two parts,
signal processing and microcontroller circuits. The signal processing
circuit is a combination of preamplifier, low-pass filter, gain control,
high-pass filter, dc offset, and clipper circuits. The proposed data
acquisition system is able to record data at a sampling rate of 300 μs,
with 10-bit resolution. It has three modes: real-time monitoring,
continuous recording, and seismic refraction. The detected seismic
signals were filtered using analog filters, which are low pass with 1
kHz and high pass with 2 Hz. A universal serial bus was utilized to
communicate between the hardware and the personal computer. A graphical
user interface based on windows operating system was developed using
Microsoft.NET Framework for transferring, processing, and analyzing the
data. The system was tested and experimental results showing the
performance of the proposed system were presented. Earth scientists can
use this system for educational seismic experiments. It can be easily
modified and used for other engineering applications.
