Proposal for an industrial structural health monitoring system based in ultrasound signal

After the development of SHM technology during the last two decades, it can be considered as a quite mature technology. This paper introduces the way to build an industrial SHM system implemented for aeronautical application, wind power generators or similar sectors. The proposal introduces the equipment on board an aircraft or on a wind generator blade. The industrial SHM system operates with Lamb waves, piezoelectric transducers, PAMELA SHM™ like electronic architecture, industrial computers and wireless communications systems. The processing of the signals obtained in the ultrasound tests is carried out on board the aircraft, more specifically in the industrial computers with pattern recognition algorithm based on fuzzy logic. The SHM system on board aircrafts or wind farms must improve the performance and reduce the maintenance costs to ensure its viability.
