Abstract:
Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur Positionsbestimmung einer Kinematik (110, 115, 120) einer bevorzugt hydraulischen Maschine, wobei die Kinematik (110, 115, 120) gegenüber einem die Positionsbestimmung durchführenden Maschinenbereich (105) peripher angeordnet ist, und wobei es zu Betriebssituationen der Maschine kommt, in denen zwischen der Kinematik (110, 115, 120) und dem die Positionsbestimmung durchführenden Maschinenbereich (105) keine signaltechnische Verbindung möglich ist, und wobei insbesondere vorgesehen ist, dass die Position der Kinematik (110, 115, 120) anhand eines von dem die Positionsbestimmung durchführenden Maschinenbereich (105) durchgeführten direkten signaltechnischen Messverfahrens (230, 235, 240, 245) ermittelt wird, dass die Position der Kinematik (110, 115, 120) in Betriebssituationen der Maschine, in denen keine signaltechnische Verbindung möglich ist, anhand eines indirekten Messverfahrens (210, 215, 220, 225) ermittelt wird, wobei anhand des direkten Messverfahrens (230, 235, 240, 245) und anhand des indirekten Messverfahrens (210, 215, 220, 225) ermittelte Positionsdaten zur Positionsbestimmung der Kinematik (110, 115, 120) gemeinsam ausgewertet werden.
Abstract:
The controller controls drive quantities of actuators (BMS, AMS, BKS, LDM, RDM, TNM) that follows drive quantity command values generated depending upon the manipulated variables of a plurality of operation means (11, 12, 13, 14, 15, 16). For this purpose, the ratio of said operation quantities to said drive quantity command values is changed depending upon an operation mode flow rate data (41), the drive quantity command values are individually weighted for the same quantity of said manipulated variable depending upon a priority mode weight data (42), at least two energy sources (FR, RP) are provided as an energy source for driving the actuators, and the timing and the amount for supplying energy from the energy source are separately controlled depending upon a pump utilization data (43) and a tilted pump plate control data (44). These control data are suitably calculated and determined (inclusive of look-up table processing) each time depending upon the operation mode of said operation means, and the selection mode of operation mode selecting switch (21) and priority mode selecting switch (22).
Abstract:
A site-aware controller and various sensors determine if objects are located within a safety dome surrounding a machine such as a construction vehicle. The site-aware controller compares data from the various sensors to determine if the machine or independently moveable implements located on the machine are capable of impacting objects within the safety dome and/or travel of the machine into restricted areas. Detection of objects within the safety dome can trigger alerts (e.g., visual and/or audible) to an operator of the machine of a particular situation. Detection of objects within the safety dome can also prevent further movement of the machine or independently moveable implements located on the machine to prevent impacting the objects. The system can also prevent movement of the machine into restricted areas.
Abstract:
An operator controllable machine is retrofitted to be operator controlled or to be automatically controlled. An electrical joystick output is provided by a manually actuated joystick control, including a joystick, to a machine control in the manually controlled machine. An interface is added between the joystick control and the machine control to permit an external source, such as a GPS receiver or a laser receiver, to apply an electrical automatic control output to the machine control, as well. The interface includes a number of optical isolation circuits and a microprocessor. The isolated microprocessor output is supplied to the machine control, which produces valve control signals to control the hydraulic valves of the machine. The application of hydraulic fluid to the hydraulic cylinders of the machine is then controlled by either the joystick control output or the automatic control output. In an intermediate range of joystick movement, the hydraulic cylinders of the machine are controlled by both outputs, resulting in a smooth transition between manual and automatic operation.

Abstract:
A method for trouble diagnosis of a working machine capable of performing a trouble diagnosis by mutually transmitting and receiving signals by communication equipment installed in the working machine and an information control center, comprising a first step for generating a first signal on the trouble of the working machine by the working machine and transmitting the first signal from the working machine to the information control center through the communication equipment, a second step for generating a second signal for specifying a trouble position in the information control center based on the first signal when the first signal is transmitted and transmitting the second signal from the information control center to the working machine through the communication equipment, and a third step for notifying an operator of the trouble information on the first and second signals.
