Adaptive pipelining of vibroacoustic signals in the problems of equipment condition monitoring

An adaptive algorithm for measuring and processing of the signals in a wide frequency range, which use pipelining of the channel selection at the lines level, at the level of analog-to-digital converter structure, and paralleling of the measurement processes at different lines, has been developed and realized in the article.

Application of these algorithms enables to increase the productivity considerably and to bring the frequency of measurement and diagnostics within the scope of a certain fieldbus up to 7,5 acts per second in case the selection length equals 400 ms and the hardware is absolutely self-supervisory. Consequently application of these algorithms enables reduction of time of response of statistical delta modulation to the change in diagnosed equipment condition.

Developed algorithms have been applied in the COMPACS^® systems used at dozens of Russian enterprises. These systems have established a reputation as fast and high-reliability measurement complexes to solve the problems of diagnostics and monitoring.
