The requirement of this project was to design and develop an advanced structural health monitoring system. This device will be used to determine the health of various critical structures like Railway carriages, Aircraft frames, Ship hulls etc. It uses high frequency sound waves to check for Fatigue and Stress/Strain.
The heart of the system is the Intel Arria10 FPGA. It is used to generate a high frequency test signal which is fed to the piezo electric transducers fixed on the structure under test. The transducers convert the signal into a high frequency soundwave which is transmitted through the structure. Other Piezo Electric sensors pick up the transmitted signal and send it back to the FPGA. The FPGA does signal processing based on an advanced algorithm and analyzes the signal to find out the health of the structure under test.
