Structural monitoring system based on the impedance method using wireless sensor networks.
The diagnosis and early detection of structural damage is essential to improve the structural integrity and provide suitable maintenance actions able to prevent possible future catastrophes. By performing impedance tests, severity and location of structural deterioration can be predicted before the damage reaches to a critical state. The capacity of these tests to characterize different types of structural damage in comparison to other methodologies has been demonstrated after more than one decade of research. However, the traditional wire-based monitoring systems are expensive, inefficient and difficult to implement. Wireless Structural Sensing is a monitoring system which provides a significant cost reduction and ease of application. The use of a wireless sensor network able to perform impedance tests eradicates the need for deployment and maintenance of long cables. Additionally, the system can be remotely controlled optimizing the life-cycle maintenance of a structure.
The proposed solution is based on monitoring the integrity of a structure using electromechanical impedance tests.
Piezoelectric materials are used as actuators to provide driving signals on the structure as well as sensing providing a self-diagnostic component minimizing maintenance and inspection cycles.
The wireless data collection from these tests makes posible a remote analysis able to predict the location and severity of posible damages in the structure.
Through a continuous monitoring of a structure a more efficient maintenance can be performed to improve its safety.
