地殻変動連続観測データ収録システムの紹介

Abstract

This manuscript introduces the data acquisition system for the continuous observation of crustal movements. The data-logger named "RL4220" was developed by us to be most suitable for our purpose. Using the RL4220, we can collect data automatically from remote places with certainty. With EWS, data collected are transformed into files of three different formats. The first of them is the "WIN format file" to be distributed. The second is to be preserved. The last is to be displayed on monitor screens. Files of the first and second format are stored in the RAID system and are able to be accessed with inter-networking.
