Apparatus and method for assisting hydraulic cylinder stroke initial calibration work
The present invention includes a stroke sensor which is arranged on a hydraulic cylinder and measures a stroke length of the hydraulic cylinder; a rotary encoder and a magnetic force sensor which measure a reset reference point to reset a value of the stroke length measured by the stroke sensor; a stroke end detection processing unit which detects a stroke end position of the hydraulic cylinder; a calibration processing unit which calibrates the measured value of the stroke length when the reset reference point and/or the stroke end position is detected; an HMI monitor which displays an entire work machine mounted with the hydraulic cylinder when an initial calibration work for the hydraulic cylinder is carried out; and a highlight display processing unit that highlights a moving portion to drive a hydraulic cylinder to be calibrated along with an indication of a driving direction.
