《施工現場》
図1は、第1の実施形態に係る車両管理装置による管理対象となる施工現場の例を示す図である。
第1の実施形態に係る施工現場Gは、切土場G1と盛土場G2とを有する。切土場G1と盛土場G2とはそれぞれ一般道路によって接続される。切土場G1と盛土場G2にはそれぞれ作業機械M1が配備される。作業機械M1は、掘削、盛土、土砂の運搬、地盤の整形、地盤の締固めなどの作業を行う。作業機械M1の例としては、油圧ショベル、ブルドーザ、ホイールローダ、ロードローラなどが挙げられる。また施工現場GではダンプトラックM2が切土場G1と盛土場G2との間を走行する。ダンプトラックM2は、切土場G1で掘削された土砂を盛土場G2へ運搬する。
図2は、第1の実施形態に係る車両管理装置の構成を示す概略ブロック図である。
第1の実施形態に係る車両管理装置10は、ダンプトラックM2が切土場G1に接近したときに、切土場G1に配備される作業機械M1のオペレータにダンプトラックM2の接近を通知し、ダンプトラックM2が盛土場G2に接近したときに、盛土場G2に配備される作業機械M1のオペレータにダンプトラックM2の接近を通知するシステムである。
車両管理装置10は、ダンプトラックM2のコンピュータから位置データを取得し、当該位置データに基づいてダンプトラックM2の切土場G1または盛土場G2への接近の有無を判定する。車両管理装置10は、ダンプトラックM2が切土場G1または盛土場G2へ接近していると判定した場合、作業機械M1のコンピュータにダンプトラックM2の接近を示す情報を出力する。

図7は、第1の実施形態に係る車両管理装置によるエリアの設定方法を示すフローチャートである。図8は、第1の実施形態に係るエリアの設定画面の表示例を示す図である。
施工現場Gの管理者は、まず出力すべき情報ごとに、図7に示す方法で各エリアAを設定する。
図9は、第1の実施形態に係る車両管理装置による情報の出力方法を示す第1のフローチャートである。図10は、第1の実施形態に係る車両管理装置による情報の出力方法を示す第2のフローチャートである。図9に係るフローチャートは、車両管理装置10が情報を出力するか否かを判定する処理を示し、図10に係るフローチャートは、車両管理装置10が各種情報を出力する処理を示す。
車両管理装置10が、エリアAに基づく情報の出力処理を開始すると、位置受信部102は、ダンプトラックM2のコンピュータからダンプトラックM2の位置を示す位置データを受信する(ステップS11)。次に、内外判定部103は、受信した位置データに基づいて、エリア記憶部201が記憶する各出力情報レコードの出力判定エリアA1および方向判定エリアA2について、ダンプトラックM2が進入したか否かを判定する(ステップS12)。
また、進入記録部104は、進入記憶部202が記憶するトラックIDとレコードIDの組み合わせのうち、関連付けられた進入時刻からすでにタイムアウト時間が経過しているものを、進入記憶部202から削除する(ステップS14)。
情報出力レコードの出力の種別が「作業機械M1に出力」を含む場合(ステップS17:YES)、通知情報出力部106は、その情報出力レコードに関連付けられた出力先の作業機械M1を特定する(ステップS18)。そして、通知情報出力部106は、その情報出力レコードに関連付けられた情報の内容を示す通知情報を、特定した作業機械M1のコンピュータに出力する(ステップS19)。他方、情報出力レコードの出力の種別が「作業機械M1に出力」を含まない場合(ステップS17:NO)、通知情報出力部106は、通知情報を、作業機械M1のコンピュータに出力しない。
情報出力レコードの出力の種別が「ダンプトラックM2に出力」を含む場合(ステップS20:YES)、通知情報出力部106は、その情報出力レコードに関連付けられた情報の内容を示す通知情報を、出力判定エリアA1に進入したダンプトラックM2のコンピュータに出力する(ステップS21)。他方、情報出力レコードの出力の種別が「ダンプトラックM2に出力」を含まない場合(ステップS20:NO)、通知情報出力部106は、通知情報をダンプトラックM2のコンピュータに出力しない。
情報出力レコードの出力の種別が「作業量の更新」を含む場合(ステップS22:YES)、作業量記録部107は、その情報出力レコードに関連付けられた情報の内容、すなわち作業種別を特定し、当該作業種別に関連付けられた作業量を作業量記憶部203から読み出す(ステップS23)。作業量記録部107は、読み出した作業量に、出力判定エリアA1に進入したダンプトラックM2の積載量を加算することで、作業量を算出する(ステップS24)。土砂の積載量は、例えばダンプトラックM2の最大積載量に基づいて定められてもよいし、ダンプトラックM2の種類ごとに定められていてもよいし、トラックスケール等による計測に基づいて定められてもよい。そして、作業量記録部107は、ステップS23で特定した作業種別に関連付けられた記憶する作業量を算出した作業量に上書きする更新指示を、作業量記憶部203に出力する(ステップS25)。他方、情報出力レコードの出力の種別が「作業量の更新」を含まない場合(ステップS22:NO)、作業量記録部107は、更新指示を作業量記憶部203に出力しない。

このように、第1の実施形態に係る車両管理装置10は、ダンプトラックM2の出力判定エリアA1への進入方向が所定方向である場合に、所定の情報を出力するか否かを決定する。これにより、管理者は、情報を出力すべき地点を含む道路の近傍に、通行方向の異なる他の道路がある場合にも、情報を出力すべき方向を指定することで、適切に情報を出力することができる。
なお、第1の実施形態に係る車両管理装置10は、ダンプトラックM2の出力判定エリアA1への進入方向が所定方向である場合に、情報を出力するが、これに限られない。例えば、他の実施形態に係る車両管理装置10は、ダンプトラックM2の出力判定エリアA1への進入方向が所定方向でない場合に、情報を出力してもよい。この場合、車両管理装置10は、ダンプトラックM2が進入した出力判定エリアA1に係るレコードIDが、当該ダンプトラックM2のトラックIDに関連付けられて進入記憶部202に記憶されている場合に、情報を出力せず、ダンプトラックM2が進入した出力判定エリアA1に係るレコードIDが、当該ダンプトラックM2のトラックIDに関連付けられて進入記憶部202に記憶されていない場合に、情報を出力する。
第1の実施形態に係る車両管理装置10は、出力判定エリアA1および方向判定エリアA2としてそれぞれ円形のエリアAを設定し、このエリアAへのダンプトラックM2の進入の有無に基づいて情報を出力する。これに対し、第2の実施形態に係る車両管理装置10は、1つの円形のエリアAを2つの扇形のエリアAに分割し、分割されたエリアAに基づいて情報の出力の要否を決定する。
図11は、第2の実施形態に係るエリア記憶部が記憶する情報の例を示す図である。

車両管理装置10のエリア設定部101は、エリアAの設定指示を受信すると、図12のステップS101からステップS103の処理を実行する。図12のステップS101からステップS103の処理は、図7のステップS01からステップS03の処理と同じである。
このように、第2実施形態に係る車両管理装置10は、出力判定エリアA1および方向判定エリアA2を、それぞれ共通の中心点を有する扇形の領域として設定する。これにより、第2実施形態に係る車両管理装置10は、第1の実施形態と同様に、情報を出力すべき地点を含む道路の近傍に、通行方向の異なる他の道路がある場合にも、適切に情報を出力することができる。
第1の実施形態に係る車両管理装置10は、出力判定エリアA1および方向判定エリアA2としてそれぞれ円形のエリアAを設定する。これに対し、第3の実施形態に係る車両管理装置10は、方向判定エリアA2と表示エリアA3とを設定し、これらの情報に基づいて出力判定エリアA1を自動的に特定する。
エリア設定部101は、方向判定エリアA2の中心座標および直径、ならびに表示エリアA3の中心座標および直径の入力を受け付ける。このとき、エリア設定部101は、出力判定エリアA4の中心座標および直径の入力を受け付けない。なお、表示エリアA3の中心座標は、車両の目的地点の一例である。
例えば、エリア設定部101は、施工現場Gの周辺の地図、方向判定エリアA2を表すサークルCおよび表示エリアA3を表すサークルCを含む設定画面を、コンピュータに出力する。このとき、出力判定エリアA1を表すサークルCは設定画面上に表示されてもよいし、表示されなくてもよい。方向判定エリアA2を表すサークルCおよび表示エリアA3を表すサークルCは、中心ハンドルC1と、境界ハンドルC2とを有する。一方、出力判定エリアA1を表すサークルCが表示される場合、当該サークルCは中心ハンドルC1と、境界ハンドルC2とを有しない。
エリア設定部101は、方向判定エリアA2および表示エリアA3の中心座標および直径を設定すると、方向判定エリアA2と表示エリアA3とを結ぶ線分を所定の比で分割した点Pの座標を算出する。エリア設定部101は、当該点Pを中心座標とし、方向判定エリアA2と同じ直径を有する円形のエリアを、出力判定エリアA1に決定する。
このように、第3実施形態に係る車両管理装置10は、出力判定エリアA1が、方向判定エリアA2の中心点と表示エリアA3の中心点とを結ぶ線分上の地点を含むエリアAとして設定される。これにより、第3実施形態に係る車両管理装置10は、出力判定エリアA1を自動で設定することができる。
第1の実施形態に係る車両管理装置10は、出力判定エリアA1および方向判定エリアA2としてそれぞれ円形のエリアAを設定し、このエリアAへのダンプトラックM2の進入の有無に基づいて情報を出力する。これに対し、第4の実施形態に係る車両管理装置10は、出力判定エリアA1に進入する前の位置情報に基づいて情報の出力の要否を決定する。

位置記録部109は、位置受信部102が受信したダンプトラックM2の位置データを、そのダンプトラックM2のトラックIDと、その位置データの取得時刻とに関連付けて、位置記憶部205に記憶させる。
位置記憶部205は、ダンプトラックM2のトラックIDと、位置データと、位置データの取得時刻とを関連付けて記憶する。つまり、位置記憶部205は、ダンプトラックM2ごとに位置データの時系列を記憶する。
また、第4の実施形態に係る車両管理装置10は、エリア設定部101の構成、およびエリア記憶部201が記憶する情報が第1の実施形態と異なる。第4の実施形態に係る車両管理装置10は、方向判定エリアA2を設定しない。図16は、第4の実施形態に係るエリア記憶部が記憶する情報の例を示す図である。図17は、第4の実施形態に係るエリアの設定画面の表示例を示す図である。
第4の実施形態に係るエリア記憶部201は、方向判定エリアA2に係る情報を記憶せず、代わりに出力判定エリアA1の進入方向を記憶する。
エリア設定部101は、出力判定エリアA1の中心座標、直径および進入方向、ならびに表示エリアA3の中心座標および直径の入力を受け付ける。
例えば、エリア設定部101は、図17に示すように、施工現場Gの周辺の地図、出力判定エリアA1を表すサークルCおよび表示エリアA3を表すサークルCを含む設定画面を、コンピュータに出力する。出力判定エリアA1を表すサークルCは、中心ハンドルC1および境界ハンドルC2に加えて、矢印C5を有する。矢印C5は、ドラッグ操作によって中心ハンドルC1回りに回転する。管理者は、コンピュータを操作し、矢印C5の方向を設定することで、出力判定エリアA1の進入方向を設定する。
図18は、第4の実施形態に係る車両管理装置による情報の出力方法を示す第1のフローチャートである。第4の実施形態に係る車両管理装置による情報の出力方法を示す第2のフローチャートは、図10と同じものであるため、省略する。
車両管理装置10が、エリアAに基づく情報の出力処理を開始すると、位置受信部102は、ダンプトラックM2のコンピュータからダンプトラックM2の位置を示す位置データを受信する(ステップS211)。位置記録部109は、受信した位置データを、ダンプトラックM2のトラックIDと、取得時刻とに関連付けて、位置記憶部205に記憶させる(ステップS212)。
このように、第4実施形態に係る車両管理装置10は、ダンプトラックM2が出力判定エリアA1に位置するときに、位置記憶部205が記憶する位置データに基づいて、ダンプトラックM2の出力判定エリアA1への進入方向が所定方向であるか否かを判定する。これにより、第4の実施形態に係る車両管理装置10は、方向判定エリアA2の設定をすることなく、情報を出力すべき地点を含む道路の近傍に、通行方向の異なる他の道路がある場合にも、適切に情報を出力することができる。
第4の実施形態に係る車両管理装置10は、位置データの時系列に基づいて、出力判定エリアA1への進入方向を特定する。これに対し、第5の実施形態に係る車両管理装置10は、方位データに基づいて出力判定エリアA1への進入方向を特定する。
図19は、第5の実施形態に係る車両管理装置の構成を示す概略ブロック図である。
第5の実施形態に係る車両管理装置10は、第1の実施形態の構成に加え、方位受信部110をさらに備える。方位受信部110は、ダンプトラックM2のコンピュータから、ダンプトラックM2が向く方位を示す方位データを受信する。第5の実施形態におけるエリアAの設定方法は、第4の実施形態と同じである。方位データは、例えばダンプトラックM2のコンピュータが備える電子コンパスにより取得される。
図20は、第5の実施形態に係る車両管理装置による情報の出力方法を示す第1のフローチャートである。第5の実施形態に係る車両管理装置による情報の出力方法を示す第2のフローチャートは、図10と同じものであるため、省略する。
車両管理装置10が、エリアAに基づく情報の出力処理を開始すると、位置受信部102は、ダンプトラックM2のコンピュータからダンプトラックM2の位置を示す位置データを受信する(ステップS311)。また、方位受信部110は、ダンプトラックM2のコンピュータからダンプトラックM2の向く方位を示す方位データを受信する(ステップS312)。
このように、第5実施形態に係る車両管理装置10は、ダンプトラックM2が出力判定エリアA1に位置するときに、方位データに基づいて、ダンプトラックM2の出力判定エリアA1への進入方向が所定方向であるか否かを判定する。これにより、第5の実施形態に係る車両管理装置10は、方向判定エリアA2の設定をすることなく、情報を出力すべき地点を含む道路の近傍に、通行方向の異なる他の道路がある場合にも、適切に情報を出力することができる。
以上、図面を参照して一実施形態について詳しく説明してきたが、具体的な構成は上述のものに限られることはなく、様々な設計変更等をすることが可能である。
上述した実施形態においては、ダンプトラックM2の走行に基づいて情報を出力する場合について説明したが、これに限られない。例えば、他の実施形態においては、他の車両の走行に基づいて情報を出力してもよい。
