Apparatus and method for determining and displaying the position of a work implement

摘要

An apparatus and method for determining and displaying a position of a work implement of a work machine in a site coordinate system is provided. First and second position sensors mounted on the work implement determine the position of the first and second position sensors and produce first and second position signals, respectively. A pitch sensor connected to the work implement senses a pitch of the work implement and responsively produces a pitch signal. A site database contains a digitized model of the work site defined by actual work site data. A controller is coupled to the first and second position sensors and the pitch sensor. The controller receives the first and second position and pitch signals, determines the position of the work implement in the site coordinate system as a function of the first and second position signals and the pitch signal, and updates the actual work site data as a function of the position of the work implement. A display, coupled to the controller, displays the position of the work implement and the digitized model of the work site. The display includes a representation of a front view of the work implement and a representation of the surface of the work site. The representation of the work implement is displayed horizontally level relative to the display.
