ことを特徴とする作業システムが提供される。
<システムの概要>
図1は作業システム100の適用例を示す模式図である。作業システム100は、作業機1と、作業機1に電力を供給する給電装置20とを備える。作業機1は、家屋に隣接した作業エリア(芝地)WAの芝刈り作業を行う。本実施形態の作業機1は、刈り取った芝を回収する機能を有しておらず、刈り取った芝は作業エリアWA上に放置されて肥料とされる。なお、作業機1は刈り取った芝を回収する機能を有していてもよく、例えば、回収袋に刈り取った芝を送り出す機構を有していてもよい。
図2は作業機1の構成及び給電装置20からの作業機1の受電態様を示す模式図(給電装置20の立面図)である。
図3は、作業システム100の回路構成を示すブロック図である。給電装置20の制御部23は、処理部24と、RAM、ROM等の記憶部25と、外部デバイスと処理部24との信号の送受信を中継するインタフェース部(I/F部)26と、を含む。処理部24は、CPUに代表されるプロセッサであり、記憶部25に記憶されたプログラムを実行し、通信部27で受信した制御指示等に基づいて、各送電部22の稼働期間等の動作を制御する。
作業システム100の動作例について再び図1を参照して説明する。作業機1は例えば管理サーバ30からの作業開始指示を受信することにより、作業エリアWAにおける芝刈り作業を開始する。作業機1は、自律的に動作し、作業エリアWA内で自走して芝刈り作業を行う。
給電装置20及び作業機1をリースするサービス形態の場合、サービスを利用するユーザに対して、作業機1で消費された電力(つまり給電装置20から給電した電力)に比例したランニングコストを課金するビジネスを想定することができる。課金量を設定するため、管理サーバ30は作業機1の消費電力を監視し、リース先のユーザに関する課金情報を生成してもよい。図4は管理サーバ30の処理部31が実行する処理例を示している。作業機1が送電区域20aにおいて給電装置20から電力の供給を受けた場合、制御部10は受電力量として電力センサ7bによる計測結果を保存し、作業機1の個体情報と共に管理サーバ30へ送信する。
給電装置20は、送電部22の送電方向を変更可能な機構を有していてもよい。図5はその一例を示す。同図の給電装置20は、支持体21にモータ等のアクチュエータを有する可動部28が設けられており、可動部28は送電部22を軸28aを回動中心として回動させる。制御部23は可動部28を駆動して送電部22の向きを変更することでその送電方向を変更する。
第一実施形態では、作業機1として芝刈り機を例示したが、除雪機、耕運機、建機等、他の種類の作業機にも作業システム100を適用可能である。また、作業エリアWAには複数の作業機、或いは、複数種類の作業機が配置されていてもよい。
管理サーバ30は、制御部10から2種類の電力の計測結果を取得(受信)する(S11)。S12で、管理サーバ30はS11で取得した情報に基づき、課金量を示す課金情報を生成する。課金量は、例えば、受電力の大きさに比例して多くされ、送電力量の大きさに比例して少なくされる。S13で管理サーバ30はデータベース32aを更新する。ここでは、S11で受信した作業機1A~1Cの個体情報に対応するユーザの情報をS12で生成した課金情報で更新する。データベース32aに記憶された課金情報は、その後、ユーザに課金量を請求する際に用いられる。
作業エリアWAに隣接して有人作業エリアを設けてもよい。図12はその一例を示すレイアウト図である。有人作業エリアWBの周囲には、給電装置20は配置されず、送電のための電波が少ない作業領域とされている。作業エリアWAには、作業機1A、1Bが配置されているが、これらは例えば遠隔操作により動作し、或いは自律式の動作とされる。これにより、作業エリアWAを無人の作業エリアとすることができる。
