DESIGN AND IMPLEMENTATION OF A SEISMIC DATA ACQUISITION PROTOTYPE SYSTEM INTENDED FOR VARIOUS APPLICATIONS

Abstract

In this work, we present a prototype of a high-precision and high-resolution seismic data acquisition system (DAQ). This system is designed for real-time monitoring, data acquisition, and visualization of seismic activity, tailored specifically for local and micro-location applications, but not limited to them. The system has various applications, including mathematical modelling of different scenarios based on collected data. These applications are relevant to geophysical research, structural health monitoring, traffic monitoring, industrial safety, household safety, and more. This prototype system acquires seismic data from the geophone or ranger seismometer connected to an analog-to-digital converter (ADC), which then transfers the data to single-board computers (SBCs). Because these SBCs possess all the capabilities of a standard PC, they ensure remote access, real-time monitoring, data acquisition, preprocessing of seismic data, and transfer of data from remote stations to the base station or server for future processing, among other functionalities. In practice, these data acquisition systems can function as standalone systems. Here, the structural components, functionality, and characteristics of this prototype system will be presented.
