Claim 8:
9. A system for planning the maintenance of a plant for shredding metal waste, the plant comprising:
at least one inlet for metal waste to be shredded;
at least one outlet for shredded metal waste;
at least one working chamber interposed between said at least one inlet and said at least one outlet;
shredding means for shredding said metal waste placed in said working chamber; and
motor means operatively connected with said shredding means;
wherein the system further includes:
sensor means operatively associated with said motor means and/or with said shredding means for monitoring within a predetermined time span at least one working parameter connected to a wear of said motor means and/or of said shredding means; and
at least one data processing unit operatively connected to said sensor means, said at least one data processing unit including:
data storage means for storing for a predetermined period of time the values of said at least one working parameter detected by said sensor means; and
an artificial intelligence software program that includes instructions to carry out the following steps:
calculating, based on said stored values, a standard deviation and a moving average thereof;
processing, based on the calculated standard deviation and moving average, a trend prediction value of said at least one working parameter in a predetermined prediction time period; and
calculating, based on said stored values and said trend value, a damage percentage probability value of said motor means and/or of said shredding means in said predetermined prediction time period;
so as to allow a plant manager to plan the maintenance of said motor means and/or of said shredding means during closure times of the system if said damage percentage probability value is above a predetermined threshold value.
