Audio Signal and Troubleshooting System Based on Wireless Sensor

Min Shen, Zhiling Tang


To explore the application of audio signal in the troubleshooting system, a sound detection system was designed. The system consists of three parts: voice acquisition node, aggregation node and host computer monitoring software. Time protocol synchronization (TPSN) algorithm was used to realize the synchronization between nodes. The algorithm and the trilateration method were applied to the system. The applications of the sound detection system in the field of fault sound source localization were realized.Wireless sensor networks were used in sound detection systems, which had many advantages. On the one hand, complicated wiring was avoided. It had the advantages of easy to set up and easy to move.On the other hand, some self-organizing and adaptive features in wireless sensor networks and some methods of synchronization and localization could be introduced. Thewhole system was more flexible and its application was more extensive.Using monitoring software, users can remotely access to the scene of the voice signal.The results showed that the system had high transmission rate, stable operation and small positioning error. Therefore, it has good application prospects.
