  • Patent number: 10060097
    Abstract: An excavation system is disclosed for use with an excavation machine having a work tool and with an IPCC. The excavation system may have a location device configured to generate a first signal indicative of a location of the excavation machine, a display, and at least one controller in communication with the location device and the display. The controller may be configured to receive a second signal indicative of a location of the IPCC, and to cause representations of the excavation machine and the IPCC to be simultaneously shown on the display based on the first and second signals. The at least one controller may also be configured to determine a swing radius of the work tool, and to selectively cause an indication of alignment between the IPCC and the swing radius to be shown on the display based on the first signal, the second signal, and the swing radius.

  • Patent number: 9803337
    Abstract: A control system implemented for in-pit crushing and conveying (IPCC) operations employing a shovel machine and a crusher machine is provided. The shovel machine includes an implement configured to excavate a material from a worksite and load the material into a hopper of the crusher machine. The control system includes a position determination module, an excavation determination module, and a path determination module. The path determination module is configured to determine one or more travel paths, with a plurality of loading positions, for the shovel machine and the crusher machine. The plurality of loading positions is based at least in part on the relative position of the shovel machine and the crusher machine and a plurality of excavation positions, such that at each of the plurality of loading positions, the implement traverses an arc passing above the hopper.

  • Patent number: 9738202
    Abstract: A system for regulating a dump rate of a truck is disclosed. The truck is configured to carry material and dump the material in a container. The system includes a first detection module and a controller in communication with the first detection module. The first detection module generates a signal indicative of a draw down rate of the container. The draw down rate corresponds to a rate at which the material is discharged from the container. The controller determines the draw down rate of the contained based on the signal received from the first detection module. The controller further determines a level of the material within the container based on the draw down rate. The controller then regulates the dump rate of the truck based on a relationship between the level of the material within the container and a threshold level.

  • Publication number: 20130245883
    Abstract: A system for analyzing machine performance is disclosed. The system may have one or more processors and a memory. The memory may store instructions that, when executed, enable the one or more processors to identify an event for a machine that includes a desired output parameter value and send a command to a component of the machine. A command value associated with the command may be determined based on the desired output parameter value, one or more machine state parameter values, and a feedback control loop. The instructions may further enable the one or more processors to determine whether the machine requires maintenance by comparing the command value to one or more historical command values each determined based on a historical desired output parameter value and one or more historical machine state parameter values.
