Leaky bucket for supervision in industrial processes

摘要

A method for reacting to disturbances that occur in industrial processes includes the steps of extracting information regarding occurrence of disturbances from an industrial process, transmitting the extracted information to a disturbance filter which includes a leaky bucket having a defined disturbance step and floor and ceiling height for the disturbances, and triggering an alarm when occurrence of disturbances in the industrial process falls without the defined disturbance step and floor and ceiling height. The present invention also provides a rigorous method of setting parameters within a leaky bucket algorithm.
