The wireless vibration monitoring using conventional Nyquist sampling techniques is costly in terms of power consumption, as it generates lots of data that need to be processed. To overcome this issue, compressive sensing (CS) can be employed, which directly acquires the signal in compressed form and hence reduces power consumption. The compressive measurements so generated can easily be transmitted to the base station and the original signal can be recovered there using CS reconstruction algorithms to diagnose the faults. However, the CS reconstruction is very costly in terms of computational time and power. Hence, this conventional CS framework is not suitable for diagnosing the machinery faults in real time. In this paper, a bearing condition monitoring framework is presented based on compressed signal processing (CSP). The CSP is a newer research area of CS, in which inference problems are solved without reconstructing the original signal back from compressive measurements. By omitting the reconstruction efforts, the proposed method significantly improves the time and power cost. This leads to faster processing of compressive measurements for solving the required inference problems for machinery condition monitoring. This gives a way to diagnose the machinery faults in real-time. A comparison of proposed scheme with the conventional method shows that the proposed scheme lowers the computational efforts while simultaneously achieving the comparable fault classification accuracy.<\/jats:p>","DOI":"10.3390\/s20010319","type":"journal-article","created":{"date-parts":[[2020,1,6]],"date-time":"2020-01-06T10:34:46Z","timestamp":1578306886000},"page":"319","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Machine Condition Monitoring Framework Using Compressed Signal Processing"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7411-7787","authenticated-orcid":false,"given":"Meenu","family":"Rani","sequence":"first","affiliation":[{"name":"Centre for VLSI and Nanotechnology, VNIT Nagpur, Nagpur 440010, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjay","family":"Dhok","sequence":"additional","affiliation":[{"name":"Centre for VLSI and Nanotechnology, VNIT Nagpur, Nagpur 440010, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raghavendra","family":"Deshmukh","sequence":"additional","affiliation":[{"name":"Centre for VLSI and Nanotechnology, VNIT Nagpur, Nagpur 440010, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"990","DOI":"10.1109\/TIM.2011.2179819","article-title":"Rotational machine health monitoring and fault detection using EMD-based acoustic emission feature quantification","volume":"61","author":"Li","year":"2012","journal-title":"IEEE Trans.
