Design and realization of multi-channel wireless data acquisition system for laboratory-scale experiments on structural health monitoring

Abstract

In this paper, we present the design steps of a low cost multi-channel accelerometer system accompanied with an open-source data acquisition software. Hardware part of the system, named KACC, is composed of battery powered tri-axial MEMS accelerometers that use IEEE 802.15.1 protocol for data transmission. The software part, named PyKACC, is developed under Python (c) open-source environment and handles initiation of data acquisition, data synchronization and data logging. The developed system is tested for synchronization and reliability via shake-table tests and results are presented.
