摘要： A system receives a plurality of data samples associated with a control valve with each of the plurality of data samples associated with a setpoint and a position. A first subset of the data samples that are in a control zone associated with normal operation of the control valve is determined. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to a minimum position of the plurality of data samples and (iii) have setpoints less than their associated positions, an alert associated with a low obstruction is indicated. In a case that a second subset of the data samples are determined to be (i) not in the first subset and (ii) close to the maximum position of the plurality of data samples and (iii) have setpoint greater than their associated position, an alert is indicated.

摘要： A system includes at least one sensor for sensing at least one of vibration, pressure, acceleration, deflection, or movement within a reciprocating engine and a controller. The controller is configured to receive a raw signal from the at least one sensor, derive a filtered knock signal using predictive frequency bands by applying a filter, derive an absolute filtered knock signal from the filtered signal, identify a maximum of the absolute filtered knock signal for each engine cycle, predict a peak pressure value of each of one or more engine cycles using the identified maximums of the absolute filtered signal and a predictive model, and adjust operation of the reciprocating engine based on the predicted peak pressure values.

摘要： Systems and methods for examining a route inject one or more electrical examination signals into a conductive route from onboard a vehicle system traveling along the route, detect one or more electrical characteristics of the route based on the one or more electrical examination signals, apply a filter to the one or more electrical characteristics, and detect a break in conductivity of the route responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route and other causes for changes in the electrical characteristics.
