摘要： A method of analyzing minerals received within a mining shovel bucket includes collecting data associated with ore received in the bucket, where the bucket includes at least one active sensor, where the ore includes one or more mineral, and where the ore is within a field of the active sensor. The method further includes determining a content of the minerals using the data, transmitting information relating to the content of the minerals to a decision support system, and sorting or processing the ore based on an output of the decision support system. Collecting data associated with the ores may include generating source signals, applying the source signals to the active sensor, collecting a response from the active sensor, and comparing the response with a reference or threshold. Other features are disclosed.

摘要： Systems and methods are provided for inhibiting the bridging of a work vehicle. A method adjusts a position of an implement of a work vehicle to inhibit a bridging of the work vehicle. The method includes: receiving, by a processor associated with the work vehicle, a chassis pitch angle associated with a chassis of the work vehicle from the Grade Control System; determining, by the processor, whether the chassis pitch angle is greater than a predefined threshold; receiving, by the processor, a current height of the implement relative to a grade from the Grade Control System; determining, by the processor, an offset to move the implement to a height above the grade based on the current height of the implement; and outputting, by the processor, the offset to the Grade Control System to move the implement to inhibit the bridging of the work vehicle.

摘要： To highly accurately plan a load loading operation by a working machine so that a load after the load loading operation has a target shape. A working machine operation system is a working machine operation system with a bucket, including: an operation recording unit which records a loading operation of a hydraulic excavator when a load is loaded from the bucket onto a carrier; a shape acquiring unit which acquires a shape of the load loaded on the carrier after the loading operation; a correlation calculation unit which calculates a correlation of the loading operation and the shape of the load; and a loading operation calculation unit which calculates the loading operation based on the correlation and the target shape of the load.

摘要： An excavator calibration framework comprises an excavator, a laser distance meter (LDM), and a laser reflector. The excavator comprises a chassis, linkage assembly (LA), sensor, implement, and control architecture. The LA comprises a boom, stick, and four-bar linkage (4BL) with the sensor on a 4BL dogbone linkage. The control architecture comprises a controller programmed to execute an iterative process at successive implement curl positions. The iterative process comprises generating a measured dogbone angle θDFMeasured, determining a height Ĥ and a distance {circumflex over (D)} between an implement node and the LDM, and determining an implement node position. The iterative process further comprises determining an estimated implement angle θGHEstimated, and generating a mapping equation comprising linkage angle inputs (θDFMeasured, θGHEstimated) and n unsolved 4BL linkage length and angle offset parameters. The controller is programmed to generate and solve a set of m mapping equations comprising the n unsolved parameters.

摘要： A framework comprises a laser distance meter (LDM), first and second laser reflectors at respective nodes, and an excavator including a chassis, a linkage assembly (LA) including a boom and stick, an implement including the nodes and tilting about axis TA, an implement sensor generating signal θtilt, and architecture. The LDM generates LDM distance signals DLDM and LDM angle of inclination signals θINC between the LDM and the laser reflectors. The architecture comprises LA actuators and a controller programmed to determine the TA relative to horizontal based on θtilt and execute an iterative process to curl the excavating implement and create bucket angles, align the LDM and the first node to determine a set of rotated IDV, align the LDM and the second node to determine a set of rotated IPV, and determine implement dimensions between the nodes based on the set of rotated IDV and IPV.
