A method is provided for dynamically monitoring material quality in a comminution system comprising a material crushing stage and a discharge stage. An imaging device captures images of comminuted material in the discharge stage, and characteristic features are extracted from the captured image for analysis with respect to at least one boundary condition. Output signals are accordingly generated corresponding to a determined comminution state of the comminuted material in the discharge stage. In one example, a crushing gap in the crushing stage is adjusted if the comminution state indicates material (or an amount of material) above a threshold size in the discharge stage. In another example, pre-screen settings in a pre-screen stage of the comminution system are adjusted if the comminution state indicates material (or an amount of material) below a threshold size in the discharge stage. Other comminution states and responses may, e.g., correspond to non-compliant material shapes, etc.

Quality monitoring and controls for a comminution system using imaging of material in a discharge stage

A system and method are provided for work cycle tracking for a self-propelled work vehicle having an integrated or drawn/pushed implement, for example comprising a scraper, and a loading container for receiving material worked thereby. First sensors generate data corresponding to operating parameters of the work vehicle, and second sensors generate data corresponding to operating parameters of the implement. Data storage includes, for each of various work states associated with the work cycle, correlations between operating parameters, of the work vehicle and/or implement, and a start or completion of the respective work state. A controller determines a current work state of the various work states associated with the work cycle based on current input data from the first and second sets of sensors, with respect to the stored correlations, and generates one or more output signals based on the determined work state.

A mobile work machine includes a frame, a material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame, and a control system configured to receive an indication of a detected object, determine a location of the object relative to the material loading system, and generate a control signal that controls the mobile work machine based on the determined location.

Machine dump body control using object detection

A control method to operate a scraper over ground, the control method comprising: receiving a signal indicative of a desired attack angle between a cutting edge of the scraper and the ground; receiving a height control signal to control a cutting edge height; receiving one or more measuring signals from one or more sensors, calculating a measured attack angle based on the one or more measuring signals; comparing the measured attack angle and the desired attack angle; and outputting at least one control signal commanding movement of a bowl of the scraper based on the height control signal and a result of the comparing the measured attack angle and the desired attack angle.

Scraper control method

A loading vehicle detects the position of a receiving vehicle relative to the loading vehicle and determines whether the receiving vehicle is to be repositioned. If so, it sends a repositioning message to the receiving vehicle and receives acknowledgement that the loading vehicle has remote control of the positioning mechanisms in the receiving vehicle. A loading vehicle operator input is detected and a position control signal is sent to the receiving vehicle to reposition it relative to the loading vehicle.

Loading vehicle and receiving vehicle control

A method and system of using real-time control for a work machine to determine strategies for operating the work machine is disclosed. The method may comprise accessing a real-time cutting time; accessing a first productivity rate, accessing a payload data; analyzing the cutting time; determining an operating strategy based at least on changes in the cutting time and the payload data; and either executing the operating strategy or notifying an operator to execute the operating strategy.

A material type identifier identifies a type of material loaded into a dump truck. When the dump truck is unloaded, a flow rate identification system identifies a flow rate of material exiting the dump truck. A flow rate controller automatically controls the tailgate actuator based on a desired flow rate of material exiting the dump body of the dump truck.

A speed control system to control retardation energy of a vehicle and a method of controlling retardation energy of a vehicle are provided. The system includes an energy storage device configured to absorb and store the retardation energy of the vehicle. The energy storage device includes a power absorption limit determined at least partially by a temperature and a state of charge of the energy storage device. The system further includes a non-energy-storing retarder configured to absorb the retardation energy of the vehicle and a controller configured to route the retardation energy to the energy storage device up to the power absorption limit and route a remaining portion of the retardation energy to the non-energy-storing retarder.

Systems and methods are described for identifying a behavior of a machine. A computer system receives a signal indicative of operation of a field machine and applies a deep learning algorithm to identify a pattern in a collection of signals stored on a computer-readable memory. The collection of signals includes the received signal indicative of operation of the field machine and other signals. A series of targeted tests are performed using a test machine while monitoring a signal indicative of operation of the test machine. A behavior is identified during the series of targeted tests that produces a signal that matches the pattern identified by the deep learning algorithm. An occurrence of the behavior is then automatically identified in the field machine in response to detecting the pattern in the received signal indicative of operation of the field machine.

A fluid control system that has a fluid assembly with a piston defined within a chamber, an electrical system having a motor configured to selectively reposition the piston, a controller in communication with the electrical system, and a sensor in communication with the controller to identify a fluid pressure value. Wherein, the controller identifies a desired fluid pressure range and selectively repositions the piston with the motor until the fluid pressure value is within the desired fluid pressure range.
