The lubricants' parameters monitoring and data collecting

Abstract

This approach is focused on Machine Intelligence for Diagnosis Automation, a research program, which promotes « preventative maintenance in manufacturing plants through the development of a fully automated prototype for oil analysis and fault prediction. The prototype is based on Artificial Intelligence (A.I.) software and online hardware ». Monitoring the condition of lubricants requires the examination of the physical, chemical and additive states, which maintain the quality of the lubricants, which is necessary for the proper functioning of the equipment. A lubricant monitoring program, especially from a qualitative point of view, will need to focus on both machine tool wear and degradation of lubricants, as well as on detecting and describing abnormal working conditions for both lubricants and machine parts. This goal can be satisfied by examining all the oils used in a company by completing laboratory tests to generate steps and acceptance classes, as well as unplanned contingency analyzes. These laboratory tests can be concentrated and classified into technology-based data sheets based on test-based information and test results, ultimately constituting consistent databases needed to generate monitoring and prevention reports. Data on the condition of the oil parameters used in the hydraulic system for lubricating machine tools have been collected during six months. The data as matrix organized, with 258648 rows (observations) and 21 columns (parameters).

An approach of classification and parameters estimation, using neural network, for lubricant degradation diagnosis

“…The data are matrixed, with 258648 rows (observations) and 21 columns (parameters). The parameters are presented in Table 1, [12].…”

“…Table 2. Data collected-the first 30 from 258648 rows and all columns of the database, are showed, [12] Experiments and in-situ trials have been carried out considering the basis of data usage using on-line analysis, which means efficiency and reproducibility, [10].…”
