Definitions

  • the invention relates to a system for position detection and control for working arms of mobile machines according to the preamble of claim 1.
  • the position of the working devices is usually detected indirectly by means of length sensors in cylinders of the hydraulic system or by angle sensors.
  • An example of the position detection by angle sensors is known from DE 100 00 771 Al.
  • the document describes a device for attitude control for working equipment mobile machines, which comprises a measuring device for measuring an angle which is formed between a determined by the position of the working device level and the direction of the gravitational force, an angle sensor for specifying an angle which between a through the position of the working means is formed at a certain plane and the direction of gravitational force, and a control means for controlling the angle between the plane of the working means and the direction of gravitational force so that the measured angle is made coincident with the predetermined angle.
  • a disadvantage of such systems is in particular the very limited possibility of detecting disturbances and inaccuracies, so that the possibilities for adjustment are also limited.
  • a equipped with such a detection system eg GPS, Global Positioning System.
  • a equipped with such a detection system eg GPS, Global Positioning System.
  • the transmission or detection of position coordinates and / or 'an inclination of the working device between at least one sensor and a transmitter / receiver unit is performed by a contact-free transmission of the signals by electromagnetic waves.
