摘要： A method of using a touch screen control panel to input and display data to control excavation by an excavator includes the steps of: (1) providing a display panel with a touch-sensitive screen at a position accessible to an operator; (2) inputting data by touching the display panel to define a desired contour of the excavated surface; (3) displaying on the display panel information representing the desired contour of the excavated surface; and (4) controlling movement of the excavator bucket to excavate the desired contour of the excavated surface. The display panel displays a sequence of screens that convey information to the operator and permit the operator to select operational modes and to input data to define the control parameters for the various operational modes.

摘要： A control system is disclosed that controls the position of a grading implement of a construction machine according to a site plan. The control system has three basic components: a stationary tracking station, a computer connected to the tracking station, and an implement controller attached to the construction machine. The tracking station measures a distance and an azimuth (horizontal) angle to a remote target located on the construction machine and communicates that position information to the computer. The computer consults a stored site plan to determine what elevation is desired at that position and calculates a corresponding zenith (vertical) angle, and communicates the desired zenith angle to the tracking station. The tracking station in turn positions a zenith-reference laser beam at the desired zenith angle. The implement controller senses the zenith-reference laser beam and adjusts the grading implement relative to the zenith-reference laser beam until its desired position is obtained.

摘要： A position sensing apparatus and method useful for surveying, marking, and grading implement sensing and control is disclosed. The position sensing apparatus includes two laser reference stations, each of which projects a laser beam that periodically sweeps in a plane across the area to be surveyed. Each time a laser beam strikes the opposite reference station, a radio timing signal is broadcast by that reference station. The position sensing apparatus also includes a portable sensing station that comprises a laser beam receiver, a radio reciever, and a programmed computer. The planar position of the portable sensing station relative to the reference stations is computed by a triangulation technique based on the relative timing of detection of the laser beams by the laser beam receiver and the reception of the radio timing signals by the radio receiver. Elevation is determined according to the height at which one of the laser beams strikes the laser beam receiver.

摘要： A grade rod and method of operation for use in a surveying system employing a laser beam which is rotated in a plane. A flexible tape formed with a graduated scale is mounted for movement in a loop within the housing. A slider on the tape carries a pair of closely spaced-apart light detectors as well as electronic circuitry which discriminates between laser beam pulses and sunlight. Output signals from the circuitry on the slider are fed into a control circuit in the housing through a flexible cable which is carried in a traveling loop. Scale indicators are mounted for movement with the slider along a fixed scale which is provided on the housing, and a manually operated cursor is mounted for movement along the housing. The control circuit includes means for driving the tape and slider in a search mode until a light pulse from the laser hits a detector, and then in a track mode for centering the detectors on the plane of the laser beam. A circuit is provided for returning the slider to its home position should the beam be interrupted for a period of time, and also for returning the slider to its home position should no laser beam be detected. A stutter-start circuit is employed for operation in a track mode for a short time period after activation before switching to the search mode.
