CORRECTION METHOD OF VERTICAL POSITION OF OPERATION DEVICE OF OPERATION MACHINE AND OPERATION DEVICE POSITION DETECTOR OF OPERATION MACHINE

摘要

PURPOSE: To make it possible to obtain accurately the vertical positions of a working device. ;CONSTITUTION: A vertical position operator 52 of a controller 50 and a front and rear position operator 54 obtain vertical positions of a bucket 22 and front and rear positions of a turning body 14 based on output signals of potentiometers 34, 40 and 46. A correction value storage circuit 56 stores up and down positions of the bucket 22 in a bucket maximum dump position and an arm miximum dump position as correction value so that an operator can control a set switch 62. An interpolating correction value operator 64 of a bucket position correction 58 obtains correction value between two correction values through an interpolation method based on two correction value stored by the correction value storage circuit 56, and it is provided to an up and down position correction operator 66. The vertical position correction operator 66 corrects up and down positions of the bucket 22 obtained by the vertical position operator 52 by using correction value outputted from the interpolating correction value operator 64.;COPYRIGHT: (C)1995,JPO
