Abstract
Automated methods and systems for analyzing data associated with an industrial process parse data entries received from devices in an industrial process, such as a mail or paper processing system. The parsing can include applying state machines to the data to identify events and produce output relating to the process for which the data is being analyzed. Statistical measures are computed for the output from each of the state machines. The statistical measures are compared to design limits. Output is displayed to the user in a format that facilitates interpretation of the data.
Claims4
A method for identifying overlapped pages in an overlap portion of a turnover sequencer in a paper processing system, the method comprising:
- (a) reading a plurality of time-tagged data entries from a plurality of machines in a mail or paper processing system;
- (b) in a first state, applying a pattern matching algorithm to each time-tagged data entry for identifying a lead edge of a sheet of paper at an inside entry photocell or an outside entry photocell of the turnover sequencer;
- (c) in response to detecting a sheet of paper at the inside entry photocell, transitioning to a second state for detecting a sheet of paper at the outside entry photocell;
- and
- (d) in the second state, in response to detecting a sheet of paper at the outside entry photocell, transitioning to a third state for producing output indicating the presence of overlapped pages in the turnover area of the turnover sequencer.
