| Description | Journal: Measurement Science and Technology The perception of vibration sources can be used to detect, classify, locate, and track autonomous underwater vehicles (AUVs), which raising great importance for ocean scientific research and navy applications. Artificial lateral lines system (ALLS) is a promising technique to sense underwater vibration sources. However, most current ALLS researches focus on the perception mechanism and biomimetic sensor design. Systematic ALLS that is ready for practical applications is still an unsolved problem. To this end, a novel biomimetic sensor system is proposed in this work for the purpose of developing a practical ALLS for AUVs. In order to determine the distribution of the developed biomimetic sensors in the AUVs, hydromechanics modelling and simulation of the artificial lateral lines were implemented to investigate the pressure response mechanisms of the AUVs in terms of the position, frequency and amplitude of the vibration source(s). Subsequently, an experimental AUV was equipped with the biomimetic sensors to evaluate the performance of the vibration sources perception. Experimental tests were conducted to analyze the relationship between the measured AUV pressure and the distance, frequency and amplitude of the vibration source. Analysis results demonstrate that the experimental measurements were consistent well with simulation results. Based on the relationship between the sensor measurements and the vibration source, a neural network model was used to identify the coordinates, frequency and amplitude of the vibration source, producing an identification accuracy of 93%. Hence, the proposed ALLS is effective for vibration sources perception of AUVs. |
