Abstract: A method of operating a cable handling system of a longwall mining machine having a shearer movable along a pan line to mine material along a mine face, the cable handling system including: i) a service line configured to carry one or more supply lines to the shearer for facilitating shearer operation, ii) a plurality of interconnected trays to accommodate the service line, iii) a plurality of sensor nodes distributed along a length of the service line, and iv) a plurality of transceivers distributed along a length of the pan line, the method comprising: a) sensing orientation, acceleration and/or position data of the service line using the plurality of sensor nodes, b) using the plurality of transceivers to receive the orientation, acceleration and/or position data from the plurality of sensor nodes and to transmit the orientation, acceleration and/or position data to a controller, and c) detecting, by the controller, an actual or imminent failure mode of the service line using analysis of the orientation, acceleration and/or position data from the plurality of the sensor nodes.

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.
