Structural health monitoring sensor development for the Imote2 platform

摘要

The declining state of civil infrastructure has motivated researchers to seek effective methods for real-time structural health monitoring (SHM). Decentralized computing and data aggregation employing smart sensors allow the deployment of a dense array of sensors throughout a structure. The Imote2, developed by Intel, provides enhanced computation and communication resources that allow demanding sensor network applications, such as SHM of civil infrastructure, to be supported. This study explores the development of a versatile Imote2 sensor board with onboard signal processing specifically designed for the demands of SHM applications. The components of the accelerometer board have been carefully selected to allow for the low-noise and high resolution data acquisition that is necessary to successfully implement SHM algorithms.
