    • A payload monitoring system (50) for an excavation machine (10) is disclosed. The payload monitoring system may have a tool (16), a first sensor (64) configured to generate a first signal indicative of a velocity of the tool, and a second sensor (62B) configured to generate a second signal indicative of a lift force of the tool. The payload monitoring system may also have a controller (60) 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.
    • 公开了一种用于挖掘机(10)的有效载荷监视系统(50)。 有效载荷监视系统可以具有工具(16),第一传感器(64),其被配置为产生指示工具的速度的第一信号;以及第二传感器(62B),其被配置为产生指示升力的第二信号 的工具。 有效载荷监视系统还可以具有与第一传感器和第二传感器通信的控制器(60)。 控制器可以被配置为基于第一和第二信号在工作循环期间记录工具的速度和提升力,并且将工作周期划分成包括加载的移动段的多个段。 控制器还可以被配置为确定加载的运动段内的时间段,在该时间段期间刀具的速度基本上是恒定的,并且基于在该时间段期间记录的升力来计算工具的有效载荷。
