図1は、本実施形態に係る施工管理システム1を模式的に示す図である。施工管理システム1は、施工計画の導出及び施工の進捗状況の可視化の一方又は両方を実施する。施工管理システム1は、コンピュータシステム2を含み、土木の施工現場3の施工計画及び施工管理を実施する。施工現場3において、作業機械が稼働する。作業機械は、例えば、施工現場3の切土、盛土、又は整地が可能な建設機械4と、土砂を運搬可能な運搬車両5とを含む。
次に、建設機械4について説明する。GPS衛星6を含むGPS(Global Positioning System:全地球測位システム)により、グローバル座標系(XgYgZg座標系)における建設機械4の車両本体の位置を示す絶対位置が検出される。建設機械4に設けられた検出装置により、ローカル座標系(XYZ座標系)における建設機械4の車両本体に対する作業部材の刃先の位置を示す相対位置が検出される。車両本体の絶対位置と、車両本体と作業部材の刃先との相対位置とに基づいて、作業部材の刃先の絶対位置が算出される。
図9は、ドローン10を模式的に示す図である。ドローン10は、施工現場3の上空を飛行可能な無人航空機である。ドローン10により、施工現場3の測量が行われる。ドローン10は、プロペラ10Pを有する無人ヘリコプターである。ドローン10は、フレーム部材10Fと、フレーム部材10Fに支持されたカメラ11と、フレーム部材10Fに設けられたプロペラ10Pとを有する。プロペラ10Pが回転することにより、ドローン10は飛行する。ドローン10は、予め決められた飛行ルートと自身の現在位置とを対比しながら、飛行ルートに沿って自動飛行するものでもよいし、地上の操作者が保持した無線操縦機からの無線信号により遠隔操作され、操作者の意図する飛行ルートを飛行するようなものでもよい。ドローン10のカメラ11により、施工現場3の現況地形が空撮される。カメラ11で取得された現況地形の画像データは、後述する記憶装置102に記憶される。記憶装置102に記憶された画像データは、無線又は有線によって、記憶装置102から、地上のコンピュータにダウンロードされる。コンピュータにダウンロードされた画像データは、コンピュータに組み込まれた変換ソフトウェアによって施工現場3の現況地形を示す3次元現況地形データに変換される。これにより、3次元現況地形データが取得される。なお、ドローン10の記憶装置102に変換ソフトウェアを記憶させ、ドローン10が有するプロセッサ101によって3次元現況地形データが生成されてもよい。
図10は、施工管理システム1のハードウエア構成を示す図である。コンピュータシステム2は、CPU(Central Processing Unit)のようなプロセッサ201と、ROM(Read Only Memory)又はRAM(Random Access Memory)のような内部メモリ及びハードディスク装置のような外部メモリを含む記憶装置202と、キーボード、マウス、及びタッチパネルのような入力デバイスを含む入力装置203と、フラットパネルディスプレイ装置のような表示装置及びインクジェットプリンタのような印刷装置を含む出力装置204と、有線通信機器又は無線通信機器を含む入出力インターフェース回路205と、を有する。
図11は、施工管理システム1を示す機能ブロック図である。コンピュータシステム2は、施工計画データ算出部20と、施工実績データ取得部21と、現況地形データ取得部22と、モードデータ取得部23と、設計地形データ取得部24と、原単位データ取得部25と、施工条件データ取得部26と、変動要因データ取得部27と、施工計画データ出力部28と、遠隔制御部29とを有する。
現況地形データ取得部22は、施工現場3の現況地形を示す現況地形データを取得する。現況地形データは、ドローン10に設けられたカメラ11で検出される。現況地形データ取得部22は、現況地形データをドローン10のカメラ11から、例えば無線で取得する。なお、現況地形データ取得部22は、建設機械4又は建設機械4とは別の車両に搭載されているステレオカメラから現況地形データを取得してもよいし、3次元レーザスキャナ装置から現況地形データを取得してもよい。
設計地形データ取得部24は、施工現場3の設計地形を示す設計地形データを取得する。設計地形は、施工会社12において作成される。設計地形データ取得部24は、設計地形データを施工会社12の情報端末13からインターネットを介して取得する。
原単位データ取得部25は、施工現場3を施工する作業機械の条件を示す原単位データを取得する。原単位データは、原単位データベース31に記憶されている。原単位データ取得部25は、原単位データを原単位データベース31から取得する。
施工条件データ取得部26は、施工現場3の施工条件を示す施工条件データを取得する。施工条件は、施工会社12において設定された事項を含む。施工条件データは、施工条件データベース32に記憶されている。施工条件データ取得部26は、施工条件データを施工条件データベース32から取得する。
変動要因データ取得部27は、施工現場3の変動要因を示す変動要因データを取得する。変動要因データは、施工現場3の自然環境のような変動要因を含み、施工の作業効率に影響を与える。変動要因データは、変動要因データベース33に記憶されている。変動要因データ取得部27は、変動要因データを変動要因データベース33から取得する。
施工実績データ取得部21は、施工現場3の施工実績を示す施工実績データを取得する。施工実績データは、建設機械4が実施した施工実績を示すデータである。建設機械4は、自己の施工実績データを取得する。建設機械4は、現況地形に接触する作業部材440の刃先440pの絶対位置の軌跡又はクローラの走行軌跡に基づいて、現況地形を検出可能である。建設機械4は、刃先440pの絶対位置から検出される現況地形と目標形状である設計地形とを比較して、設計地形に対してどれくらい作業(土砂の切土又は盛土)が進んだのかを示す施工実績データを取得可能である。施工実績データ取得部21は、施工実績データを建設機械4から無線で取得する。なお、コンピュータシステム2が、建設機械4から現況地形データを取得し、現況地形と設計地形とを比較することによって、施工実績データを取得してもよい。なお、施工実績データ取得部21は、建設機械4又は建設機械4とは別の車両に搭載されているステレオカメラにより検出された現況地形と設計地形とを比較することによって施工実績データを取得してもよいし、3次元レーザスキャナ装置により検出された現況地形と設計地形とを比較することによって施工実績データを取得してもよい。
モードデータ取得部23は、施工の優先項目を示すモードデータを取得する。モードデータの詳細は後述する。施工の優先項目は、施工現場3の作業者Ma又は施工会社12の作業者Mbによって選択される。作業者Maは、携帯端末7の入力装置703又は情報端末8の入力装置803を操作して、施工の優先項目を入力する。作業者Mbは、情報端末13の入力装置133を操作して、施工の優先項目を入力する。モードデータ取得部23は、施工の優先項目を示すモードデータを、携帯端末7、情報端末8、及び情報端末13の少なくとも一つから、例えばインターネットを介して取得する。
施工計画データ算出部20は、現況地形データ取得部22で取得された現況地形データと、設計地形データ取得部24で取得された設計地形データと、原単位データ取得部25で取得された原単位データとに基づいて、施工現場3の施工計画を示す施工計画データを算出する。
施工計画データ出力部28は、施工計画データ算出部20で算出された施工計画データを出力する。施工計画データ出力部28は、結果データベース34に施工計画データを出力する。以下の説明においては、施工計画データ出力部28を単にデータ出力部28と称することもある。
サポートセンター14の情報端末15は、コンピュータシステム2の施工計画データ算出部20と同等の機能を実行可能である。例えば、情報端末15は、施工計画データ算出部20が実行可能な3次元画像データの生成を実行可能である。情報端末15は、施工計画データ算出部20の代わりに、建設機械4から取得した施工実績データを3次元画像データに加工すること、施工会社12において作成された設計図面である2次元設計地形データ又は3次元設計地形データを3次元画像データに変換することを実行可能である。生成された3次元画像データは、入出力インターフェース回路155及びコンピュータシステム2を介して、携帯端末7及び情報端末8に送信される。
また、コンピュータシステム2は、設計地形データに基づいて、建設機械4を遠隔操作するための制御信号を出力する遠隔制御部29を有してもよい。遠隔制御部29は、建設機械4をリモートコントロールする。施工現場3からの要望により設計地形が変更された場合、遠隔制御部29は、変更後の設計地形データに基づいて、建設機械4を遠隔操作するための制御信号を出力することができる。
次に、施工管理システム1を用いる施工管理方法について説明する。図12は、施工計画方法を示すフローチャートである。
以上説明したように、本実施形態によれば、施工計画データ出力部28は、表示装置704に、現況地形データ、設計地形データ、施工範囲データ、切土計画データ、及び盛土計画データの少なくとも二つを並べて3次元表示させる。したがって、施工前の施工計画のうち、現況地形データ、設計地形データ、施工範囲データ、切土計画データ、及び盛土計画データの少なくとも二つが対比された状態で視覚化されるので、作業者又は管理者は施工計画を感覚的に迅速に把握することができる。そのため、施工現場の生産性の向上を図ることができる。
図2から図6を参照して説明したように、建設機械4は、車両本体400と、車両本体400に対して相対移動する作業部材440とを有する。作業部材440は、現況地形に接触する刃先400pを有する。建設機械4は、刃先440pの絶対位置に基づいて、現況地形を検出するプロセッサ401(ブレード制御装置401A、バケット制御装置401B)を有する。車両本体400の絶対位置は、GPS受信器406によって検出される。建設機械4は、車両本体400に対する刃先440pの相対位置を検出する検出装置420(420A、420B)を備えている。車両本体400の絶対位置と、検出位置420の検出結果とに基づいて、刃先440pの絶対位置が求められる。刃先440pによって施工現場3が施工され、現況地形が形成される。すなわち、刃先440pの絶対位置が分かることにより、現況地形の表面のあるメッシュ点の絶対位置が分かる。したがって、プロセッサ401は、刃先440pの絶対位置を検出することによって、現況地形を検出することができる。
施工管理システム1の第2の実施形態について説明する。上述の実施形態と同様、本実施形態に係る施工管理システム1は、施工現場の現況地形を示す現況地形データを取得する現況地形データ取得部22と、施工現場の設計地形を示す設計地形データを取得する設計地形データ取得部24と、現況地形データと設計地形データとを照合して、施工現場の施工計画を示す施工計画データを算出する施工計画データ算出部20と、施工現場の施工実績を示す施工実績データを取得する施工実績データ取得部21と、施工計画データ出力部28と、を備える。
施工管理システム1の第3の実施形態について説明する。図36は、本実施形態に係る施工管理システム1の一例を示す模式図である。上述の実施形態と同様、施工現場3において、建設機械4が稼働する。作業者Maは、携帯端末7を所持する。
施工管理システム1の第4の実施形態について説明する。図39は、本実施形態に係る施工管理システム1の一例を示す模式図である。設計地形データは、施工会社12又はサポートセンター14において作成される。
