A cost effective three-axis accelerometer for building structure health monitoring

摘要

To ensure critical structures safety operation, the building structure monitoring system is needed. The accelerometers and temperature sensors are usually used to achieve reliable inspection of structures. The main goal of this work is the realization of a customized building structure health monitoring, based on three 1-axis accelerometers, Gateway, analog to digital converter (ADC), and data logger. The proposed Building Structure Health Monitoring Device (BSHMD) achieves the features of low cost by using three 1-axis accelerometers with the data synchronization problem being solved, and easily installation and removal. Furthermore, we develop a packet acquisition program to receive the sensed data and then classify it based on IP address, time, and date. Compared with 3-axis accelerometer, our proposed 1-axis accelerometers based device achieves 64.3% cost saving. Compared with previous structural monitoring device, the BSHMD achieves 89% area saving. Therefore, with using the proposed device, the real-time diagnosis system for building damage monitoring can be conducted effectively.
