System and method for dig detection

摘要

A system for determining an operational state of a machine is provided. The system includes an implement position sensor configured to generate a position signal indicative of a position of an implement. The system further includes a pressure sensor configured to generate a pressure signal indicative of a pressure of a cylinder of the machine. The system also includes a controller communicably coupled to the implement position sensor and the pressure sensor. The controller is configured to receive the position signal and the pressure signal. The controller is further configured to determine a weight of a payload of the machine based on the received signals. Further, the controller is configured to determine a dig status of the machine based, at least in part, on a rate of change of the weight of the payload and the position of the implement.

1. A system for determining an operational state of a machine, the system comprising:
an implement position sensor configured to generate a position signal indicative of a position of an implement; a pressure sensor associated with a cylinder, the cylinder coupled to the implement, the pressure sensor configured to generate a pressure signal indicative of a pressure of the cylinder; and a controller is communicably coupled to the implement position sensor and the pressure sensor, the controller configured to:
receive the position signal indicative of the position of the implement;receive the pressure signal indicative of the pressure of the cylinder;determine a weight of a payload of the machine based on the received position and the pressure signal;determine a dig status of the machine based, at least in part, on a rate of change of the weight of the payload and the position of the implement, wherein the dig status comprises any one of: a first state corresponding to an unknown operation associated with the implement, and a second state corresponding to a dig operation not being performed by the implement;identify the first state as the dig status of the machine;detect if a fault condition is associated with at least one of the received position signal and the pressure signal; andtransition the dig status of the machine from the first state to the second state if the fault condition is not detected.
