PROBLEM TO BE SOLVED: To provide a boom posture detecting device capable of obtaining a posture of a boom even if an electric wave receiving state of a GPS device is bad.SOLUTION: A boom posture detecting device is equipped with: a GPS device 20 which measures a position of a tip end of a boom; posture detectors 31 and 32 for detecting a posture of the boom; and a computing device 40. The computing device 40 obtains a correction value for correcting detection values of the posture detectors 31 and 32 to a posture of the boom acquired from a measurement value of the GPS device 20, when the reliability of measurement of the GPS device 20 is high, and obtains the posture of the boom by correcting the detection values of the posture detectors 31 and 32 with the correction value, when the reliability of the measurement of the GPS device 20 is low. The posture of the boom can be obtained even when an electric wave receiving state of the GPS device 20 is bad and the reliability of the measurement is low.SELECTED DRAWING: Figure 2
【課題】GPS装置の電波受信状態が悪い場合でもブームの姿勢を求めることができるブーム姿勢検出装置を提供する。【解決手段】ブームの先端の位置を測位するGPS装置20と、ブームの姿勢を検出する姿勢検出器31、32と、演算装置40とを備え、演算装置40は、GPS装置20の測位の信頼性が高い場合に、姿勢検出器31、32の検出値をGPS装置20の測位値から求められるブームの姿勢に補正するための補正値を求め、GPS装置20の測位の信頼性が低い場合に、姿勢検出器31、32の検出値を補正値で補正してブームの姿勢を求める。GPS装置20の電波受信状態が悪く、測位の信頼性が低い場合でもブームの姿勢を求めることができる。【選択図】図2
