One Example of Mobile Hardware Platform for Sound Acquisition in Industrial Environment

In this paper we propose one possible solution of microprocessor hardware platform for acquisition of sound signals from coal mill in thermal power plant. Proposed platform is based on Raspberry Pi 3B microcomputer, running Raspbian operating system. Sound acquisition is performed by command-line sound recorder arecord, which is part of the software package available with this operating system. Experimental results showed that this platform provides recordings comparable to recordings acquired by professional sound recorder, for particular application.
