Misura della potenza elettrica assorbita da diverse stazioni sismiche

Abstract

The use of seismic recorders in a monitoring network requires a knowledge of certain characterizing parameters that indicate the performance and consequent reliability of the value measurements provided for various fields of experimental seismology. These parameters are normally indicated in the datasheets drafted by the manufacturers, which are used for reference when choosing a recorder to meet the requirements of each specific application, from both the technical and financial perspectives. Among the parameters of most interest to seismic stations is electrical power absorption. Knowledge of this parameter facilitates appropriate sizing of the photovoltaic panel-based power system in order to ensure continuous operation of remote seismic stations regardless of weather conditions.
The present work involved measuring the electrical power absorption under different recorder operating conditions to verify both the accuracy of the values reported in the datasheets, and to compare the different devices being used at our Institute. Correlation of the results with the experimental setups under which the seismic data loggers operated also made it possible to optimize the software settings for a prototype recorder under development by our team, in order to regulate certain functional blocks with the aim of minimizing power consumption.
