Acoustic Signal Acquisition System Based on Wireless Sensor Networks and Compressed Sensing Theory
In this paper the limitations of the existing acoustic signal acquisition system have been analyzed, a novel acoustic signal acquisition system based on wireless sensor networks(WSN) has been proposed. The hardware structure and software design has been described in detail. The compressed sensing theory and the compression algorithm are also introduced. We use the system to collect the crawling voice of granary castaneum adults. The results show that the proposed system is reasonable and feasible, and with the data compression algorithm based on compressed sensing theory, the proposed system can effectively implement the remote, real-time, reliable transmission of high-volume acoustic signal measurements.
