Embedded Shock and Vibration monitoring system is considered to be the most effective method for analyzing the performance of the underwater vehicle and also for early fault detection. Shocks and vibrations of underwater vehicles cause the systems sometimes malfunction, faulty and sometimes fail. To avoid the failure of the systems the shocks and vibrations of the vehicle is to be evaluated and controlled. For monitoring these parameters a sophisticated monitoring system is required. The main aim of this work is Development and Testing of an embedded FPGA based 3-axis simultaneous shock and vibration system for monitoring of shocks and vibrations in the underwater vehicle. The shock and vibration monitoring system consists of piezoelectric accelerometers which perform well over the wide range of temperature and resists damage due to severe shocks and vibrations to acquire the vibration signals. This project proposes a data acquisition system to monitor and analyze the shock and vibration data along the three axes (horizontal, vertical, axial).During the real time mode the system can be used to monitor either shock or vibration signals from accelerometer representing the shock or vibration data along the three axes is recorded and stores in the NAND flash memories. During the offline mode, data will be retrieved to PC through USB. Retrieved data will be processed and plots will be created using MATLAB.
