AI Technical Summary
Technical Problem
Existing work machines face deviations in motion due to sensor detection value inaccuracies, leading to discrepancies between intended and actual postures of components like attachments, which can disrupt automated operations.
Method used
A work system incorporating a posture detector with sensors and an information acquisition device to monitor the posture of components like a boom, arm, and bucket, using three-dimensional information to calculate and compare detected and calculated postures, and transmit error signals when deviations occur.
Benefits of technology
Enables reliable monitoring of sensor detection values by evaluating deviations, ensuring accurate posture detection and preventing automated operation errors by notifying operators of discrepancies.

Abstract
Provided is a work system (1) enabling a detection value as to the posture of a detection target to be monitored. The detection target is selected from among a lower traveling body (21), an upper turning body (22), a boom (31), an arm (32), and a bucket (33). The work system (1) includes: a posture detector that detects the posture of a detection target; an information acquisition device (5) that acquires three-dimensional information of the detection target; a posture calculation part that calculates the posture of the detection target based on the acquired three-dimensional information; and a deviation calculation part that calculates a deviation between the posture detected by the posture detector and the posture calculated by the posture calculation part.
