Abstract
Description
ここでマシンガイダンスは、トータルステーション(TS:Total Station)、GNSS(Global Navigation Satellite System)等の計測技術を利用して作業機械の操作を支援する技術である。このマシンガイダンスによれば、オペレータの操作を適切に支援して、作業効率、安全性、作業精度を向上することができる。
図1は、本発明の第1実施形態に係る作業支援システム1を示す図であり、図2は、ブロック図である。
この作業支援システム1は、作業機械である油圧ショベル2において、マシンガイダンスの機能によりこの油圧ショベル2を操作するオペレータの操作を支援する。
ここで油圧ショベル2は、無限軌道により自走する本体3にブーム4、アーム5、バケット6が順次設けられる。なお作業支援システム1は、油圧ショベルに限らず、例えば地盤改良に使用する作業機械等、土木、建築の作業に使用される各種作業機械を広く適用することができる。
また検出装置11A、11B、11C、11Dのセンサには、IMU(INERTIAL MEASUREMENT UNIT)センサが適用される。しかしながらセンサは、IMUセンサに限らず、3軸以外のセンサを適用するようにしてもよく、姿勢情報を検出可能な種々の構成を広く適用することができる。またセンサは、直接、可動部の姿勢を検出する情報を取得可能な構成に限らず、例えば地表までの距離を測距する測距用センサのように、間接的に可動部の姿勢を検出可能な構成を広く適用することができる。
また検出装置11A、11B、11C、11Dの電源に係る電池には、乾電池が適用されるものの、種々の一次電池、二次電池を広く適用することができる。
さらに検出装置11A、11B、11C、11Dは、本体装置12からの要求により電池の残量情報を検出して本体装置12に通知する。ここで電池の残量検出は、例えば端子電圧により検出する場合、内部抵抗により検出する場合等、種々の検出手法を広く適用することができる。
なお支援情報には、例えばバケット6の先端位置から施工目標までの距離情報が適用される。
ここで作業計画の情報は、例えば作業計画を管理する管理用コンピュータよりダウンロードして取得することができ、またこの携帯情報端末装置13に直接入力して形成することができる。
無線通信部21は、制御部25の制御による無線通信によるデータ通信により、検出装置11A、11B、11C、11D、携帯情報端末装置13との間で各種のデータを送受し、さらに油圧ショベル2から水温等の情報を取得する。
画像表示部23は、例えば液晶表示パネル等により構成され、本体3に搭乗したオペレータに各種の画像情報を通知する。
なおこの支援情報の提供は、例えば施工目標までの棒グラフ状のセグメント表示により実行することができるものの、加工目標までの数字による距離表示等、種々の手法を適用することができる。またバケット6の先端が施工目標に近づくに従って音程が変化するように警報音を発生して聴覚により確認可能に支援情報を提供する。
なお支援情報の提供は、携帯情報端末装置13により実行してもよい。
制御部25は、始動スイッチとしてのイグニッションキーの操作(IG-ON)により油圧ショベル2が動作を開始すると、この処理手順を開始し、検出装置(センサ機器)11A、11B、11C、11Dから電池の残量情報を取得する(残量情報取得ステップ:SP2)。
制御部25は、この取得した残量情報により電池情報記憶部24の記録を更新する(SP3)。
ここで図4は、この制御部25による電池情報記憶部24の更新処理を示す図表である。なお図4においては、検出装置11A、11B、11C、11Dをそれぞれセンサ1、2、3、4により示す。
また制御部25は、それまで電池情報記憶部24に記録して保持していた残量情報と、ステップSP2で取得した残量情報とにより単位時間当たりの残量減少量を計算し、電池情報記憶部24の記録を更新する。この図4の例では、検出装置11A、11B、11C、11Dでそれぞれ単位時間当たりの残量減少量は、4%/h、2%/h、2%/h、4%/hである。
また制御部25は、電池残量を単位時間当たりの残量減少量で割り算し、電池残時間を算出して更新する。この図4の例では、検出装置11A、11B、11C、11Dでそれぞれ電池残時間は、10時間、15時間、23時間、10時間である。
図5は、この制御部25の処理の説明に供する図である。制御部25は、作業計画の情報に設定された作業開始予定時刻、作業終了予定時刻、作業中止予定時刻及び作業再開予定時刻から、油圧ショベル2による作業が連続する時間を検出し、マシンガイダンス利用想定時間帯に設定する。またこのマシンガイダンス利用想定時間帯を日毎に集計し、マシンガイダンス利用想定時間の合計時間を算出する。
また電池交換に要する時間以上、油圧ショベル2による作業が予定されていない時間帯に、電池交換に要する時間により電池交換可能な作業休止時間帯を設定する。
なお作業機械の作業計画の情報を、例えば複数の作業機械の作業計画を管理する管理用コンピュータ等の外部情報機器より取得するようにしてもよい。このようにすれば、例えば複数の作業機械を管理する管理装置から作業計画の情報を取得して、複数の作業支援システムで電池を適切に管理することができる。
また17日、18日、19日、20日のマシンガイダンス利用想定時間の合計時間(MG合計時間)は、それぞれ7時間、6時間、6時間、4時間である。
図5の例では、この処理手順に係る処理を17日の就業開始時に実行していることになり、17日及び18日のマシンガイダンス利用想定時間の合計時間が7時間、6時間であり、電池残時間が10時間(図4)であることにより、図6に示すように、検出装置11A、11B、11D(センサ1、2、4)については、18日の就業直後の電池交換可能な作業休止時間帯を検出して電池交換時期に設定する。また検出装置11Cについては、続く19日及び20日のマシンガイダンス利用想定時間の合計時間が6時間、4時間であり、電池残時間が23時間であることにより、19日の電池交換可能な作業休止時間帯を電池交換時期に設定する。
なおこれらにより図3の処理手順においては、ステップSP4-SP5の処理が、電池の残量情報及び作業機械の作業計画の情報に基づいて、電池の交換時期を予測する予測ステップである。
これに対してお知らせの時刻となっている場合、画像表示部23、音声出力部22、携帯情報端末装置13を介して電池交換時期を通知する(通知ステップ:SP7)。
なおこのお知らせの時刻は、事前に設定された通知のための時間だけ、電池交換時期より遡った時点であり、例えばオペレータが事前に設定した時間が適用される。
この表示画面の下部に、電池交換時期の通知を示すメッセージが表示される。なおこのメッセージの表示は、電池交換時期の通知であることを示す「電池交換時期のお知らせ」に続いて、対応する交換時期を示す「2020/08/18 8:00~9;00の間に」が表示され、電池交換する検出装置を特定する「センサ1、センサ2、センサ4」が表示され、さらに「電池交換を行って下さい」のメッセージが表示される。
また携帯情報端末装置13においても、音声により電池交換を通知するようにしてもよい。
このように携帯情報端末装置を介して電池の交換時期を通知すれば、オペレータが作業機械に搭乗していない場合でも交換時期を通知することができる。
以上、本発明の実施に好適な具体的な構成を詳述したが、本発明は、本発明の趣旨を逸脱しない範囲で、上述の実施形態の構成を種々に変更することができる。
