Abstract: A new method is disclosed for monitoring the operation of a corrugated board production plant, the method provides for detecting at least one operational parameter of a functional unit of the plant, for example a current absorbed by a motor. Then, the current value of a statistical function of the operational parameter is calculated in a current temporal window. The maximum value and the minimum value of the same statistical function are calculated based on historicized data of the operational parameter in question. By comparing the current value of the statistical function and the maximum and minimum values, a piece of information of predictive diagnostics is obtained.

Abstract: The plant for producing a corrugated board comprises one or more single facers and a double facer, as well as respective unwinders for unwinding reels of paper webs. Arranged along the production line, in suitable positions, are thermographic cameras which acquire images through which it is possible to trace the various characteristics of the cardboard, for example the moisture content thereof, detect manufacturing defects, after which it is possible to intervene on one or more process parameters so as to eliminate the causes of the defects.

Abstract: The methods provides for detecting at least one operational parameter of a functional unit of the plant and calculating a current value of at least a first statistical function of said operational parameter in a current temporal window, the current value of said first statistical function defining a first coordinate of a point of current operation of the functional unit. A step is also provided of verifying whether the point of current operation is within a range of allowable values of the first statistical function, the values contained in said range of allowable values corresponding to a correct operation of the functional unit. In case the point of current operation is outside the range of allowable values, the position is determined of the point of current operation with respect to the range of allowable values and a statistical diagnosis is provided of the cause of the deviation of the current value from the range of allowable values based on said position.
