図3は、本実施形態に係る管理システム1の一例を示す機能ブロック図である。管理システム1は、管理装置3と、制御装置30と、制御装置40とを含む。
図4は、実施形態に係る排土場DPAの一例を模式的に示す図である。図4に示すように、排土場DPAに複数の排土位置Mが設定される。排土位置Mは、無人車両2の排土作業が実施される位置である。無人車両2は、走行コースデータに基づいて排土位置Mに走行し、排土位置Mに排土する。
図5は、実施形態に係る通知装置50の一例を模式的に示す図である。通知装置50は、表示装置を含む。図5に示すように、進入禁止エリアARが表示装置に表示される。図5に示す例において、進入禁止エリアARの輪郭を示す点線が表示装置に表示される。なお、進入禁止エリアARが特定の色で表示装置に表示されてもよい。表示装置は、運転者が進入禁止エリアARを認識できる表示形態で表示すればよい。これにより、運転者は、進入禁止エリアARの位置を確認することができる。
図6は、実施形態に係る管理方法の一例を示すフローチャートである。進入禁止エリア設定部3Bは、進入禁止エリアARを設定する(ステップS1)。
以上説明したように、本実施形態によれば、進入禁止エリアARを有人車両9に通知する通知部3Dが設けられる。進入禁止エリアARが通知装置50の表示装置に表示されることにより、有人車両9の運転者は、進入禁止エリアARに進入しないように運転操作することができる。進入禁止エリアARに有人車両9が進入した場合、通知装置50から規定の通知形態で警報が出力されることにより、運転者は、有人車両9が進入禁止エリアARに進入したことを認識し、進入禁止エリアARから出るように運転操作することができる。無人車両2の作業エリアに有人車両9が進入することが抑制されるため、作業現場の安全性の低下が抑制される。
図7は、コンピュータシステム1000の一例を示すブロック図である。上述の管理装置3、制御装置30、及び制御装置40のそれぞれは、コンピュータシステム1000を含む。コンピュータシステム1000は、CPU(Central Processing Unit)のようなプロセッサ1001と、ROM(Read Only Memory)のような不揮発性メモリ及びRAM(Random Access Memory)のような揮発性メモリを含むメインメモリ1002と、ストレージ1003と、入出力回路を含むインターフェース1004とを有する。上述の管理装置3、制御装置30、及び制御装置40のそれぞれの機能は、プログラムとしてストレージ1003に記憶されている。プロセッサ1001は、プログラムをストレージ1003から読み出してメインメモリ1002に展開し、プログラムに従って上述の処理を実行する。なお、プログラムは、ネットワークを介してコンピュータシステム1000に配信されてもよい。
上述の実施形態において、進入禁止エリアARに有人車両9が進入した場合、管理装置3は、進入禁止エリアARに存在する無人車両2の走行を停止してもよい。
