Audio Signal and Troubleshooting System Based on Wireless Sensor

Abstract

<p class="0abstract"><span lang="EN-US">To explore</span><span lang="EN-US"> the application of audio signal in the troubleshooting system, a sound detection system </span><span lang="EN-US">wa</span><span lang="EN-US">s designed. The system consists of three parts: voice acquisition node, aggregation node and host computer monitoring software. Time protocol synchronization </span><span lang="EN-US">(</span><span lang="EN-US">TPSN</span><span lang="EN-US">)</span><span lang="EN-US"> algorithm </span><span lang="EN-US">wa</span><span lang="EN-US">s used to realize the synchronization between nodes. The algorithm and the trilateration method </span><span lang="EN-US">we</span><span lang="EN-US">re applied to the system. The application</span><span lang="EN-US">s</span><span lang="EN-US"> of the sound detection system in the field of fault sound source localization </span><span lang="EN-US">we</span><span lang="EN-US">re realized.</span><span lang="EN-US">Wireless sensor networks </span><span lang="EN-US">we</span><span lang="EN-US">re used in sound detection systems, which ha</span><span lang="EN-US">d</span><span lang="EN-US"> many advantages. On the one hand, complicated wiring </span><span lang="EN-US">wa</span><span lang="EN-US">s avoided. It ha</span><span lang="EN-US">d</span><span lang="EN-US"> the advantages of easy to set up and easy to move.</span><span lang="EN-US">On the other hand, some self-organizing and adaptive features in wireless sensor networks and some methods of synchronization and localization c</span><span lang="EN-US">ould</span><span lang="EN-US"> be introduced. The</span><span lang="EN-US">whole system</span><span lang="EN-US"> was</span><span lang="EN-US"> more flexible</span><span lang="EN-US"> and i</span><span lang="EN-US">ts application </span><span lang="EN-US">wa</span><span lang="EN-US">s more extensive.</span><span lang="EN-US">Using monitoring software, users can remotely access to the scene of the voice signal.</span><span lang="EN-US">The results show</span><span lang="EN-US">ed</span><span lang="EN-US"> that the system ha</span><span lang="EN-US">d</span><span lang="EN-US"> high transmission rate, stable operation and small positioning error. Therefore, it has good application prospects.</span></p>
