System and method for dig detection

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;
• and
• transition the dig status of the machine from the first state to the second state if the fault condition is not detected.
