METHOD AND APPARATUS FOR MONITORING MATERIAL REMOVAL USING MOBILE MACHINERY

摘要

A method (100-106 and 108-110) and apparatus (40, 50, 60) for monitoring in real time the removal of material from a land site (12) by a mobile machine (20). A digitized three dimensional model (104, 106) includes a model of the material to be removed and its characteristics. The instantaneous machine positon signal is generated by means (50) located in the machine (20). Loading signals are generated by the machine (20) and loading position is recorded in response to the loading signal. The invention includes a payload measurement system (65, 123) which measures each discrete load. The characteristics of the site material at the recorded loading position are correlated to the material removed from the site. A dynamic site database (66) is used to update the site (12) as material is removed and direct the machinery to a desired state.
