发明名称 HYDRAULIC CYLINDER STROKE OPERATION DIAGNOSIS ASSISTING DEVICE AND HYDRAULIC CYLINDER STROKE OPERATION DIAGNOSIS ASSISTING METHOD
摘要 A hydraulic cylinder stroke operation diagnosis assisting device includes: movable portions that are sequentially supported by a vehicle body in a rotatable manner; a hydraulic cylinder between the vehicle body and each movable portion or between the movable portions to support the movable portions in a rotatable manner; a stroke sensor in the hydraulic cylinder to measure a stroke length of the hydraulic cylinder; a reset sensor measuring a reference reset point in which a value of the stroke length measured by the stroke sensor is reset; a stroke end detection unit detecting a stroke end position of the hydraulic cylinder; a calibration unit calibrating the measured value of the stroke length when the reference reset point and/or the stroke end position are detected; and a monitor displaying at least the measured value of the stroke length and a calibration state by the calibration unit.

主权项 1. A hydraulic cylinder stroke operation diagnosis assisting device comprising: movable portions that are sequentially supported by a vehicle body in a rotatable manner; a hydraulic cylinder that is disposed between the vehicle body and each movable portion or between the movable portions so as to support the movable portions in a rotatable manner; a stroke sensor that is disposed in the hydraulic cylinder so as to measure a stroke length of the hydraulic cylinder; a reset sensor that measures a reference reset point in which a value of the stroke length measured by the stroke sensor is reset; a stroke end detection unit that detects a stroke end position of the hydraulic cylinder; a calibration unit that calibrates the measured value of the stroke length when the reference reset point and/or the stroke end position are detected; and a monitor that displays at least the value of the stroke length measured by the stroke sensor and a calibration state by the calibration unit on a screen.
