Abstract

Design and Development of software controlled stand-alone instruments have been identified as the most vital component of national and international programs on earthquake hazard and risk management. For in depth investigation and studies, the development of precise instruments designed around computer is emerging very fast. Interfacing of personal computer with seismic instrument is an important design task. A design technique based on minimum hardware has been worked out around the parallel printer interface of computer. Hardware and Software for this purpose has been designed to make the instrument interact with computer through parallel port interface. Incorporation of software for seismic signal analysis has been considered the extremely powerful tool to view and analyze seismic data collected by seismic instruments. In this paper efforts have been made to describe the various design aspects for interfacing of Seismic Data Recorder and Analyser to computer through parallel printer port and computation steps incorporated in the software tool for seismic data analysis.
