  • Machine to-machine communication system for payload control
    Patent number: 8386134
    Abstract: A method for enhancing payload control is disclosed. The method includes removing material during a plurality of work cycles with at least one loading machine and associating the loading machine relative to at least one haulage machine. The method also includes determining the relative locations of the loading machine and the haulage machine and, during the plurality of work cycles, loading removed material into the haulage machine with the loading machine. The method also includes determining payload and payload distribution within the haulage machine at least before a last work cycle of the plurality of work cycles and communicating to the loading machine, via a machine-to-machine communication system, the amount and position within the haulage machine of additional payload desired in at least the last work cycle of the plurality of work cycles for desired payload and payload distribution.
