摘要： An apparatus for controlling a material feed system of a paver is disclosed. The material feed system includes a feeder conveyor and a spreader auger. The apparatus includes a sensor that monitors the amount of material at the edge of the screed and responsively produces an actual material height signal. A rotary switch produces a desired material height signal indicative of a desired amount of material at the edge of the screed. A controller receives the actual and desired material height signals, determines a desired rotational speed of the auger in response to the difference between the signal magnitudes, and produces a command signal to rotate the auger at the desired speed. An electrohydraulic system receives the command signal and rotates the auger at the desired rotational speed.

摘要： Methods and systems are provided for performing protocol conversions in an environment including a work machine having one or more modules coupled to one or more data links. Such methods and systems may leverage one or more gateways to perform tunneling, translating, and bridging operations. Tunneling processes may include receiving a message from a source module in a first protocol, encapsulating the message within transmission units of a second protocol, and transmitting the encapsulated message via the second protocol. Translating processes may include receiving, by the gateway, a message in a first data link protocol including a parameter identifier. The gateway may match the parameter identifier with a parameter identifier included in a translation table and scale associated parameter data using a scale factor corresponding to a second data link protocol. The gateway may then provide the scaled parameter data to a module using the second data link protocol.

摘要： A control device for operating a machine is disclosed. The control device includes a joystick having a central axis and being universally moveable along a first and second axis in a plane perpendicular to the central axis, and a rotatable operator control station that houses the joystick. A joystick position sensor senses the position of the joystick and responsively generates a set of operator command signals corresponding to the displacement and direction of the joystick from the central axis in the first and second axis. A operator station position sensor senses the rotational position of the operator station and responsively generates a position signal. A controller receives the operator command and position signals, and responsively transposes the function of the joystick axis to correspond to the orientation of the machine.

摘要： In one aspect of the present invention, a control system for a floating screed assembly for an asphalt paving machine is disclosed. The screed assembly includes a main screed and extension screed unit. An electrohydraulic device extends and retracts, as well as, raises and lowers the extension screed unit relative to the main screed unit. The electrohydraulic device additionally pivots the extension screed unit relative to the main screed unit about a horizontal axis. Position sensors produce position signals in response to the position of the extension screed unit. A controller receives the position signals and produces command signals to control the extending, retracting, and pivoting of the extension screed unit to a desired position.
