Testing of wind turbine towers using wireless sensor network and accelerometer

Structural Health Monitoring (SHM) is commonly used in the health assessment of wind turbines. The system is installed during construction of the structure and consists of wired sensors connected to a central data acquisition unit via cables. In most cases, the data acquisition unit is located on the wind turbine itself. SHM is verified by comparison of results over time from wireless sensor systems. This study presents the Supervised Event Server Health Monitoring System (SESHMS) as a relatively simple, economical wireless system for use within the arena of structural health assessment.
