図1は、本実施形態における農業支援システム1000の構成例を模式的に示す図である。図2は、サーバコンピュータ100の概略的なハードウェア構成を例示するブロック図である。農業支援システム1000は、サーバコンピュータ100(以下、「サーバ100」と表記する)と、1以上の端末装置200とを備える。複数の農業機械300が、有線または無線のネットワーク60を介して農業支援システム1000に互いに通信可能に接続され得る。図1に、3台の農業機械300がネットワーク60を介して農業支援システム1000に接続される接続例が示されている。ただし、農業支援システム1000に接続される農業機械300の台数は任意である。農業支援システム1000は、通信遅延の低減またはネットワーク負荷の分散の観点から、1以上のエッジコンピュータをさらに備えていてもよい。本実施形態において、サーバ100の一部が制御装置として機能する。
サーバ100は、農業機械300から離れた場所に設置されたコンピュータであり得る。サーバ100は、通信装置10と、制御装置20と、記憶装置30とを備える。これらの構成要素は、バスを介して相互に通信可能に接続される。サーバ100は、リクエスト信号を処理したり、農業機械300が実行する農作業のスケジュールを管理したり、ストレージに格納されたデータを活用して農業を支援したりするクラウドサーバとして機能し得る。
図3は、端末装置200の概略的なハードウェア構成を例示するブロック図である。
図4は、本実施形態における農業機械300の外観の例を示す斜視図である。図5は、作業機400が装着された状態の農業機械300の例を模式的に示す側面図である。本実施形態における農業機械300は、作業機400が装着された状態の農業用トラクタ(作業車両)である。農業機械300は、トラクタに限定されず、また作業機400が装着されている必要もない。
まず、農業機械300による自動走行の動作の例を説明する。
本実施形態における農業機械300は、農業機械300に搭載された記憶装置に記録された作業スケジュールに従って圃場間の移動、各圃場での農作業を自動で実行する。作業スケジュールは、複数の作業日にわたって行われる複数の農作業に関する情報を含む。具体的には、作業スケジュールは、作業日ごとに、どの時刻に、どの農業機械が、どの圃場で、どの農作業を行うかを示す情報を含むデータベースであり得る。作業スケジュールは、ユーザが端末装置200を用いて入力した情報に基づいて、サーバ100のプロセッサ21によって作成され得る。以下、作業スケジュールの作成方法の例を説明する。
本実施形態における農業支援方法は、サーバ100の制御装置20に実装される。図14は、本実施形態における農業支援方法の一例による手順を示すフローチャートである。当該農業支援方法は、端末装置200または操作端末153からの農作業の支援要請を待つことと(ステップS10)、支援先の圃場における農作業の種類に応じて農作業の支援をさせる農業機械300を決定することと(ステップS20)、農業機械300による農作業の支援の完了を待つことと(ステップS30)、課金情報を端末装置200または操作端末153に送信することと(ステップS40)を含む。
次に、図15Aおよび図15Bを参照してサーバ100(主に制御装置20)および農業機械300の動作の例を説明する。以下で説明する、農業支援システム1000に接続される1以上の農業機械300は、第1農業機械300Aおよび第2農業機械300Bを含む。ただし、1以上の農業機械300は3以上の農業機械を含み得る。
先ず、第2農業機械300Bの操作端末153から制御装置20に第1リクエスト信号が送信される。第1リクエスト信号は、農作業の支援を要求した第2農業機械300Bの位置情報を含んでいる。
制御装置20は、第2農業機械300Bの位置情報及び記憶装置30に記憶されている環境地図を参照し、第2農業機械300Bが位置する圃場F1を特定する。また、制御装置20は、作業スケジュールを参照し、例えば保管場所510に停止している1以上の農業機械300の中から作業支援させる農業機械を決定する。
制御装置20は、第1リクエスト信号に応答して、第1農業機械300Aを第2農業機械300Bが位置する圃場F1に移動させる指令を含む第2リクエスト信号を、制御装置180Aに送信する。例えば、制御装置20は、保管場所510に停止している第1農業機械300Aの制御装置180Aに、圃場F1の位置情報を含む第2リクエスト信号を送信する。
制御装置20は、作業支援させる農業機械を決定すると、作業支援させる農業機械を決定したことを第2農業機械300Bに通知する。
第2農業機械300Bは、目標経路R2aが変更されるまでは、目標経路R2aに沿って圃場F1内を自動走行して農作業を行っている。制御装置180Bは、制御装置20からの通知を受け取ると、圃場F1における第2農業機械300Bの自動運転に必要な目標経路を変更する。制御装置180Bは、制御装置20からの通知を受け取ると、圃場F1における目標経路R2aを目標経路R2bに変更する。
制御装置180Aは、第2リクエスト信号を受信すると、第1農業機械300Aに圃場F1に移動させるための制御を開始する。制御装置180Aは、制御装置20から第2リクエスト信号を受信すると、第1農業機械300Aが支援先である圃場F1における農作業を行うための目標経路R1を作成する。
制御装置180Aは、第1農業機械300Aを目標経路R1に沿って自動走行させる。制御装置180Aは、第1農業機械300Aが開始地点ST1に到達すると、インプルメントを作動させて、開始地点ST1から第1農業機械300Aに作業を開始させる。制御装置180Aは、操舵装置106などの動作を制御することによって、目標経路R1に沿って進行方向に第1農業機械300Aを自動で走行させながら作業させる。
制御装置180Bは、第2農業機械300Bを目標経路R2bに沿って自動走行させる。制御装置180Bは、操舵装置106などの動作を制御することによって、目標経路R2bに沿って進行方向に第2農業機械300Bを自動で走行させながら作業させる。
