1. A control method for a control unit configured for predicting a deterioration in a component part of a passenger moving system having the control unit, the control method for the control unit comprising:
activating at least one sensor in communication with the component part;
performing data acquisition to acquire data from the at least one sensor; and
processing the data;
repeating said processing step over a first specified time period;
triggering a command signal to initiate a maintenance operation and generating a predictive alert, both in response to the processed data reaching a predetermined threshold;
continuously checking measured values from the acquired data to identify any outlier data values that exceed the predetermined threshold, said checking step occurring simultaneously with said step of processing the data; and
immediately filtering out the outlier data values so that they are not processed in, and do not influence, said processing step.
