<p>A system for machine condition monitoring through vibration analysis. At least one vibration sensor (9), amplifying and digitizing means (7) and a microprocessor with associated memory (18) are combined into a local initial data processing unit disposed adjacent to the machine for forming and storing vibration data in the form of time series. These time series are periodically transferred via remote communication means (17, 15, 14) to a control monitoring unit (1) for further processing of the time series. For this purpose, the control monitoring unit (1) includes frequency analysis means (22), pattern recognition means (23) and associated computer equipment. Hereby, each local initial data processing unit can be operated without human surveyance.</p> |
