英文摘要 | Sound waves are the most straightforward way of communication existing in nature. A tremendous amount of funds, manpower, and time are spent, however, when high-end technologies are involved to facilitate signal tracking of acoustic waves. As a result, a design that realizes directional signal tracking of acoustic waves via the advantages of the grey system theory is proposed in this paper. This article consists of three parts. First, a set of sound collecting sensors capable of reception in sixteen directions is fabricated from piezoelectric devices. The sensors sample the collected analog signal data and convert it to a digital signal for further analysis, operation, and processing, with the eigenvalue of the signal source acquired simultaneously. Second, the obtained eigenvalue is analyzed by utilizing the grey relational grade according to the grey system theory to calculate the sound targets in sixteen directions. Third, output control is implemented by fuzzy control on the target to be controlled with feedback from the position sensor. In the end, these three parts are integrated to make a signal-tracing system that is fast, highly accurate, and resilient to disturbance. |
