发明名称 Method for monitoring the work cycle of mobile machinery during material removal
摘要 The invention is a method for monitoring a work cycle of a mobile machine on a land site. The mobile machine has a bucket and a body that is adapted to rotate about a fixed point of reference. The method includes the steps of determining an angular velocity of the body, determining the body is stopped based on the angular velocity, determining a duration of time the body is stopped, and determining the work cycle in response to the duration of time the body is stopped.
