Abstract: A work cycle determination system for a fracking pump is provided. The work cycle determination system includes a pressure sensor adapted to generate a signal indicative of a pressure generated by the fracking pump, and a controller communicably coupled to the pressure sensor. The controller receives the signal indicative of the pressure generated by the fracking pump over a predefined period of time. The controller identifies a boundary of a work cycle within the predefined period of time by analyzing the signal. The controller also determines a peak pressure of the work cycle and a time duration of the work cycle. The controller further determines a type of the work cycle of the fracking pump based on the peak pressure and the time duration of the work cycle.
