Abstract: The present disclosure is directed to a payload calculation system for use with a work implement having at least two linkage members. The payload calculation system may have at least one state sensor configured to measure a state of the at least two linkage members. The payload calculation system may also have a processing device in communication with the at least one state sensor. The processing device may account for changes in a center of gravity of each of the at least two linkage members. The processing device may also be configured to use the at least one state sensor to determine a mass of a payload moved by the work implement.

Abstract: A data acquisition system for an excavation machine having a power source configured to drive a tool through a work cycle is disclosed. The data acquisition system may have a first sensor associated with the power source to generate a first signal indicative of a performance of the power source, and a second sensor associated with the tool to generate a second signal indicative of a performance of the tool. The data acquisition system may also have a controller in communication with the first and second sensors. The controller may be configured to record the first and second signals, and partition the work cycle into a plurality of segments. The controller may be further configured to link the performance of the power source and the performance of the tool together with one of the plurality of segments during which the associated first and second signals were recorded.

Abstract: A payload monitoring system for an excavation machine is disclosed. The payload monitoring system may have a tool, a first sensor configured to generate a first signal indicative of a velocity of the tool, and a second sensor configured to generate a second signal indicative of a lift force of the tool. The payload monitoring system may also have a controller in communication with the first sensor and the second sensor. The controller may be configured to record the velocity and the lift force of the tool during a work cycle based on the first and second signals, and partition the work cycle into a plurality of segments including a loaded moving segment. The controller may also be configured to determine a period of time within the loaded moving segment during which the velocity of the tool is substantially constant, and calculate a payload of the tool based on the lift force recorded during the period of time.

Abstract: A control system for an excavation machine is disclosed. The control system may have a work tool movable to perform an excavation work cycle, at least one sensor configured to monitor a speed of the work tool and generate a signal indicative of the monitored speed, and a controller in communication with the at least one sensor. The controller may be configured to record the monitored speed of the work tool during each excavation work cycle, and compare the signal currently being generated to a maximum speed recorded for a previous excavation work cycle. The controller may be further configured to partition a current excavation work cycle into a plurality of segments based on the comparison.

Abstract: The present disclosure is directed to a payload calculation system for use with a work implement. The payload calculation system may have a state sensor configured to measure a state of the work implement. The payload calculation system may further have a processing device configured to calculate a mass of a payload moved by the work implement. The processing device may be configured to use the measured state to compensate the calculation of the mass for centrifugal, inertial, and frictional forces of the work implement caused by the work implement rotating about a vertical pivot.
