Real-time production takt calculation method and system based on waveform feature matching

The invention discloses a real-time production takt calculation method and system based on waveform feature matching, and relates to the field of industrial big data processing, and the method comprises the following steps: S1, collecting original current data in real time; s2, preprocessing the original current data by using a cubic spline interpolation method, and performing resampling to obtain standard current data with a sampling time interval of t; s3, standard current waveform features are extracted, and a historical standard current waveform feature library is established and used for storing historical standard current data waveform features and equipment operation states corresponding to the historical standard current data waveform features; s4, matching the standard current waveform characteristics with historical standard current data waveform characteristics, judging the operation state of equipment, and obtaining the number of processing waveforms; s5, counting the number of processing waveform
