Abstract
Description
1-1.水質管理ユニットの構成
図1に示される水質管理ユニット110は、水質管理システム100と、複数の水質センサ30(図1に示す例では、水質センサ30A,30B)と、を備える。
制御装置10の入力ポート20は、1つの水槽90に対して1つ用意される。例えば、制御装置10Aの入力ポート20Aは水槽90Aに対応して設けられ、制御装置10Aの入力ポート20Bは水槽90Bに対応して設けられる。入力ポート20に接続された水質センサ30は、入力ポート20に対応する水槽90内に設置され、水槽90内の飼育水の水質を測定する。例えば、制御装置10Aの入力ポート20Aに接続された水質センサ30は、制御装置10Aの入力ポート20Aに対応する水槽90A内に設置され、水槽90A内の飼育水の水質を測定する。また、制御装置10Aの入力ポート20Bに接続された水質センサ30は、制御装置10Aの入力ポート20Bに対応する水槽90B内に設置され、水槽90B内の飼育水の水質を測定する。同様に、制御装置10B,10C,10D,10E,10Fの入力ポート20は、それぞれ水槽91A,91B,92A,92B,93A,93B,94A,94B,95A,95Bに対応して設けられる。
制御装置10は、予め定められた測定条件が成立した場合に、制御装置10に接続された水質センサ30による水質の測定を行う。測定条件は、測定時期を定める条件である。測定条件は、予め設定された測定条件と、外部(例えば記憶端末40)からの指示を受けた場合に成立する条件と、を含む。測定条件の設定は、例えば記憶端末40、より具体的には図5に示す表示画像にて行われる。測定条件は、上述した測定形態ごとに設定される。
制御装置10は、複数の水槽90にそれぞれ設置される水質センサ30と接続可能とされている。制御装置10は、水質センサ30が着脱可能に接続される入力ポート20を複数備える。制御装置10は、入力ポート20に接続された水質センサ30の測定値を受信し、測定値を受信した入力ポート20の識別情報および測定値を相互に関連づけて記憶し、外部に出力する。この制御装置10によれば、水質センサ30の測定値、および測定値を受信した入力ポート20の識別情報を相互に関連づけて記憶し、外部に出力することができる。このため、1つの制御装置10で、複数の水槽90での測定値に基づく水質情報を、水槽90ごとに区別して管理することができる。したがって、この構成によれば、コストの上昇を抑制し、作業者の労力を低減しつつ、複数の水槽90での水質に関する情報を管理することできる。
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。また、上述した実施形態や後述する実施形態の様々な特徴は、矛盾しない組み合わせであればどのように組み合わされてもよい。
