Abstract

In this study, an embedded data logger for realtime data transmission and signal storage of the seismic acceleration measurement data has been investigated. A database was planned in order to transform mini-SEED and QSCD20 formats among the data structure required for recording, storage and transmission of data in National disaster prevention system, and the sensor module, Global Positioning System(GPS) module and the power board were integrated by designing a 24bit Analog-Digital Converter(ADC) circuit on the main board. The developed data logger could record, save and transmit the measurement data more sensitively as over-sampled data, where a threshold-type trigger method was applied. The firmware to be installed in the data logger was developed to process time synchronization using GPS, AD transformation and the storage/transmission of multi-format data structure. This was designed to have a high portability to the existing seismic acceleration measurement system along with the web interface for operating environment configuration of the data logger, and the data transformation, storage/transmission and the rate of data transmission according to required specifications were tested, compared and verified. The design of the embedded platform developed in this study is expected to expand the applicability of the existing seismic acceleration measurement sensor and the integrated management system of seismic acceleration measurement data.
