Intelligent Structural Health Monitoring System

Keywords: structural health monitoring, wireless sensor networks, monitoring systems, fault diagnosis

Structural health monitoring is a new approach to provide diagnosis of the structure’s condition during its life using the sensor data. An intelligent monitoring system with wireless sensor networks can provide reliable information about the structure’s condition, replace visual inspections, provide ease of installation and configurability, save costs, and ultimately save people’s lives. The wireless sensing and networking technologies required in intelligent monitoring systems are developed. Data mining and statistical analyses are used to extract relevant information from the sensor data for damage detection. Model-based methods are studied to estimate the location and extent of damage or predict the remaining lifetime. There is a large number of possible applications including bridges, buildings, wind power turbines, ships, masts, spacecraft, forest harvesters, lift trucks, reach stackers, various crane systems, pipe systems, and amusement park rides. New business opportunities for the service sector emerge and the results can be utilized in other critical areas as well
