Description

【０００１】
【発明の属する技術分野】
本発明は、乳温管理装置の作動監視装置及びその監視方法に関し、特に監視結果を通信端末に送信することにより、乳温管理装置の異常を速やかに知ることができることを特徴とするものである。
【０００２】
【従来の技術】
乳牛から搾乳された生乳は、バルククーラーと呼ばれる貯蔵タンクに入れられて、保存される。該バルククーラーは、貯蔵タンクと冷凍機を組み合わせたもので、搾乳された生乳を予め定められた温度に保ち、生乳の集乳までの間の細菌の繁殖や、腐敗を防止するものである。前記バルククーラーを用いた生乳の集乳工程は図１２に示すようになされる。即ち、細菌の繁殖を防止するために、バルククーラー内部の洗浄ＰＳ１が行なわれ、その後、初回の搾乳ＰＳ２１によってバルククーラー内に受け入れられた生乳は保冷ＰＳ３され、次回の搾乳ＰＳ２２まで予め定められた温度に保たれる。次回の搾乳ＰＳ２２が終了すると前記と同様に生乳は保冷ＰＳ３され、以後複数回（２乃至４回）の搾乳が行なわれる。その後、生乳が集乳Ｇされ、バルククーラーが空になると前記同様にしてバルククーラー内部の洗浄ＰＳ１が行なわれる。
【０００３】
前記洗浄は、一般的には、集乳後にぬるま湯洗浄、アルカリ洗浄及び酸洗浄、すすぎ、殺菌剤循環がなされ、各洗浄時には洗浄時間、洗浄温度が定められている。また、搾乳時及び保冷時には、周知のＨＡＣＣＰ（Hazard Analysis and Critical Control Points）システムに準拠した所定の時間における生乳の温度の推奨値が提示されている。このような従来のバルククーラーは、貯蔵タンク内の生乳の温度変化をデータロガーなどで収集し、そのデータを参照して、生乳の安全性を確認しているに留まっている。そのために、前記データから貯蔵タンク内の生乳の温度変化が異常であった場合、保存されている生乳の品質が問題であることを知ることができるが、その生乳を廃棄せねばならず、酪農家は多大な損失を被る。このような被害を防止し、細菌の繁殖を防止するために、生乳が集乳された後にバルククーラー内を洗浄、殺菌する技術が公知である（例えば特許文献１参照。）。
【０００４】
また、冷凍機等の故障あるいは／及び停電によりクーラーの温度が上昇することもある。このようなクーラーの温度上昇に対する警報装置として「冷却貯蔵庫の温度警報装置」に関する技術も公知である（例えば特許文献２参照。）。この警報装置は、庫内温度を検出するセンサと、このセンサの出力に基づいて警報装置（ブザー、ランプ）を制御する制御装置（マイクロコンピュータ）とから成り、この制御装置（マイクロコンピュータ）は庫内温度が設定温度より高い第１の高温警報温度に達し、且つ、その状態が所定の警報除外時間の経過まで継続された場合に警報装置（ブザー、ランプ）を駆動すると共に、第１の高温警報温度より高い第２の高温警報温度に達した場合は、警報除外時間の経過を待つこと無く、警報装置（ブザー、ランプ）を駆動するものである。

【発明が解決しようとする課題】
しかし、バルククーラー内を洗浄、殺菌する洗浄方法として例えば、アルカリ洗浄が知られているが、該アルカリ洗浄では、操作ミスまたは洗浄機の故障により洗浄時にクーラー内の温度が所定の温度に達せず、充分な殺菌ができないという問題が生じることがあった。また、搾乳は、生乳が集乳されるまでの間に複数回なされるのが一般的である。そのため、生乳の受け入れ時には、先に搾乳された生乳は、バルククーラー内で冷却されているが、新たに搾乳された生乳は温度が高く、冷却されている生乳に新たに搾乳された生乳が混入されると、バルククーラー内の生乳の温度は一時的に上昇する。その後バルククーラーにより冷却されて所定の温度に低下する。新たな生乳の混入によってバルククーラー内の生乳の温度は変化するが、停電の場合、クーラーが故障している場合、冷凍機のスイッチの入れ忘れなどの操作ミス等により、生乳の保冷時にバルククーラー内の生乳の温度が上昇したままになると、生乳が腐敗する場合がある。あるいは、洗浄後にクーラーが故障している場合や、あるいは操作ミスによりバルククーラー内の温度が低下しないような場合もある。また、過冷却によってバルククーラー内の生乳が凍結する場合もある。このように、バルククーラーは生乳の品質を保持するために、バルククーラーの洗浄、生乳の受け入れ、その保冷など、多岐に及ぶ動作態様がある。特に、生乳の追加などによりバルククーラー内の生乳の温度は一時的に上昇することがあり、単純にバルククーラー内の生乳の温度上昇を測定するのでは生乳の品質を保持することができない。即ち、その作動情況を監視して異常な状態になった時のみ、速やかに酪農家に通知すると同時に、場合によっては集乳業者や検査機関にも連絡することが重要である。
【０００７】
冷却貯蔵庫が異常な状態になった時に通知する技術として前記、特許文献２に開示されている冷却貯蔵庫の温度警報装置では、庫内温度が設定温度より高くなった場合に、ブザー、ランプにより警報を発することができる。しかし、酪農家は、クーラーの洗浄時や生乳の搾乳時、保冷時にクーラーの傍にいて、その動作状態を常時監視することが困難である。特に農作業時や夜間の就眠中にその問題がある。したがって、バルククーラー内の生乳の温度が上昇した時、あるいは過冷却になった時に、これを速やかに知ることができる乳温管理装置の作動監視装置及びその監視方法の開発が望まれていた。
【０００８】
本発明は、かかる問題を解決して、酪農家が乳温管理装置の傍にいなくとも乳温管理装置の作動監視ができ、装置の異常時にその異常を速やかに知ることのできる乳温管理装置の作動監視装置及びその監視方法を提供することを目的としてなされたものである。

【発明の実施の形態】
まず、発明の理解を容易にするために、本発明の概略について説明する。本発明は、乳温管理装置の作動監視装置及びその監視方法に関し、所定の監視時間内に、予め定められた温度範囲から外れた時に、警報を発するものである。処理を、洗浄監視処理と、受け入れ監視処理と、保冷監視処理とに分けて、各処理毎に第１の監視情報あるいは／及び前記第１の監視情報より緊急度の高い第２の監視情報を通信端末に送信するものである。
【００３２】
図１により本発明の実施形態の構成について説明する。バルククーラー２を用いた乳温管理装置は、バルククーラー制御手段１により、生乳３の温度を制御すると共に、洗浄、殺菌の制御を行なう周知の乳温管理装置である。バルククーラー２内の液体（生乳または洗浄液または排液）の温度及びバルククーラー２が設置されている室内の温度を測定する温度測定手段４がＡ／Ｄ変換器５に接続されている。なお、図１では図示を省略してあるが、洗浄液が注入／排水される注入口及び排水口の近く、及びバルククーラー２の底部近くに生乳の温度を測定する前記温度測定手段４が、それぞれ設置される場合もある。パーソナルコンピュータ（以下作動監視制御手段と称する）６は、その内部にＲＡＭ、ＲＯＭ、複数のタイマーを備え、前記Ａ／Ｄ変換器５及びバルククーラー制御手段１のほかに、表示手段７、キーボード８、モデム９、プリンタ１２が接続されている。更にモデム９は、周知のインターネット接続網１０に接続され、周知のインターネット接続サービスを利用してパーソナルコンピュータ６から通信端末（携帯電話機、パーソナルコンピュータ、携帯通信端末など）１１及び工場あるいは／及び検査機関１３に電子メールを送信することができる。又、前記作動監視制御手段６は、前記通信端末からのデータを、モデム９を介して受信する受信手段を備えている。前記Ａ／Ｄ変換器５、パーソナルコンピュータ６、表示手段７、キーボード８、モデム９、プリンタ１２は、停電時に備えて図示していない無停電電源が接続されているようにしてもよい。
【００３３】
作動監視制御手段６には、温度測定手段４から得たデータがデータ格納手段の一つであるＲＡＭに、また、図２又は図７に示す監視時間、監視温度及び監視情報を含む作動監視データがデータ格納手段の一つであるＲＯＭに、それぞれ格納されている。前記温度測定手段４から得た測定直後のデータは、Ａ／Ｄ変換器５によりディジタルデータに変換され、データ格納手段の一つであるＲＡＭに格納される。なお、Ａ／Ｄ変換器５は、後述するデータの比較処理が可能なように、測定直後のデータが読み出せる機能を備えているものであれば、データの蓄積機能を備えた周知のデータロガーなどであってもよい。
【００３４】
また、作動監視制御手段６の図示していない前記ＲＯＭには、以下の処理プログラムが格納されていて、図示していないＣＰＵ（中央処理装置）により実行される。前記処理プログラムとは、前記ＲＡＭに格納された温度測定手段４から得た測定データと前記監視温度を比較する比較処理プログラム（比較処理手段）、前記乳温管理装置の洗浄時の作動を監視する洗浄監視処理プログラム、前記乳温管理装置の生乳受け入れ時の作動を監視する受け入れ監視処理プログラム、前記乳温管理装置の生乳受け入れ後の保冷時の作動を監視する保冷監視処理プログラムである。以下、前記洗浄監視処理プログラム、受け入れ監視処理プログラム、保冷監視処理プログラムを作動監視制御プログラムと称する。なお、前記以外に、インターネットに接続し、通信端末１１や工場あるいは検査機関１３との間で電子メールを送受信する処理プログラム及び入出力機器の制御処理プログラムは、周知のプログラムであり、作動監視制御手段６の前記ＲＯＭに格納されていて、前記ＣＰＵ（中央処理装置）により実行される。
【００３５】
作動監視制御手段６には、バルククーラー制御手段１が接続され、信号線１ａを介してバルククーラー制御手段１からバルククーラー２の状態、即ち、バルククーラー２の洗浄工程、生乳の受け入れ工程、あるいは生乳の保冷工程の何れかの状態信号が送信される。これ以外に、作動監視制御手段６とバルククーラー制御手段１を接続せず、バルククーラー制御手段１の制御状態に応じて操作者がキーボード８からコマンドを入力し、あるいはファンクションキーを押下して前記作動監視制御プログラムを起動するようにしてもよい。また、酪農家により異なる搾乳回数や洗浄回数などは、予め定めておいて、ファンクションキーを押下して選択するようにしてもよく、あるいは前記キーボード８から入力するようにしてもよい。
【００３６】
次に、前記実施形態の構成により実施される第１の実施形態について説明する。第１の実施形態は、処理の途中の一定時間経過後に第１の監視情報又は第２の監視情報を発するものである。そして、洗浄監視処理では、洗浄開始後から洗浄終了時までの間の乳温管理装置内の温度を監視し、終了時に第１の監視情報か、第２の監視情報を通信端末に送信する。受け入れ監視処理では、生乳を投入後の生乳の温度を監視し、第１の時間経過時に第１の監視情報を、生乳を投入後の第２の時間経過時に第２の監視情報を通信端末に送信する。保冷監視処理では、生乳を投入完了後の生乳の温度を監視し、所定の温度範囲を超えた時、所定の時間経過後に第２の監視情報を携帯あるいは固定通信端末（以下、携帯電話機として説明する。）に送信する。
【００３７】
第１の実施形態における作動監視制御手段６で使用するデータ構造を図２により説明する。前記作動監視制御手段６のＲＯＭに格納されている監視時間欄、監視温度欄及び監視情報欄の（ｔ１乃至ｔ４）、（ＴＵ、ＴＬ、ＴＵ１乃至ＴＵ３、ＴＬ１乃至ＴＬ３）及び監視情報からなる作動監視データ（第１の情報、第２の情報）は、処理欄に示す洗浄監視処理、受け入れ監視処理、保冷監視処理で使用される。監視情報欄のＴＯは、測定対象温度である。また、監視時間（ｔ１乃至ｔ４）、監視温度（ＴＵ、ＴＬ、ＴＵ１乃至ＴＵ３、ＴＬ１乃至ＴＬ３）及び監視情報に括弧内に付加されて記述されている値、あるいは監視情報の表し方は、一例であって、これ以外の値あるいは表し方であってもよい。また、監視情報は、第１の監視情報と第２の監視情報とがあり、第２の監視情報は、第１の監視情報より緊急度の高い情報である。即ち、酪農家が重大な損害を被る可能性のある障害が発生したことを示し、携帯電話機１１に電子メールを送信する時に、第１の監視情報と第２の監視情報とを、例えば「注意」、「警告」などの具体的な情報で表す。なお、第１の監視情報Ｌ１が出力されたのち、該第１の監視情報Ｌ１が消去されていなくとも、第２の監視情報Ｌ２が出力される条件が成立した場合には、第１の監視情報Ｌ１を消去して第２の監視情報Ｌ２が出力される。
【００３８】
第１の実施形態における発明の理解を容易にするために図３乃至図５を用いて前記洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理における監視情報を得る方法について説明する。図３乃至図５において、横軸は時間を、縦軸は乳温管理装置内の生乳等の液体の温度を表し、第１の監視情報と第２の監視情報を、それぞれＬ１、Ｌ２で表す。また、洗浄監視処理の処理開始時におけるバルククーラー２内の液体の温度をＴｂ、受け入れ監視処理及び保冷監視処理の処理開始時における生乳の温度をＴＳ０で表す。
【００３９】
まず、洗浄監視処理について図３により説明する。符号イ、ロ、ハは、洗浄監視処理の例を示すものである。洗浄の開始ｔｓから終了ｔｅまでの時間をｔ４とする。洗浄開始ｔｓから洗浄終了ｔｅまでの時間ｔ４の間に乳温管理装置内の液体の温度（最高値）が温度Ｔ７（上限温度ＴＵ）以下であって、該温度Ｔ７より低い温度Ｔ８（下限温度ＴＬ）を超える場合には、第１の監視情報Ｌ１が洗浄終了ｔｅ時に作動監視制御手段６から出力される。又、洗浄開始後から洗浄終了時までの間に乳温管理装置内の液体の温度（最高値）が温度Ｔ８以下の場合には、第２の監視情報Ｌ２が洗浄終了ｔｅ時に作動監視制御手段６から出力される。
【００４０】
例えば、符号イで示す洗浄例では、洗浄開始ｔｓから洗浄終了ｔｅまでの時間ｔ４の間に乳温管理装置内の液体の温度（最高値）が温度Ｔ７を超えている。かかる場合には第１の監視情報Ｌ１及び第２の監視情報Ｌ２何れも出力されない。即ち、洗浄が正常に終了している。又、符号ロで示す洗浄例では、洗浄開始ｔｓから洗浄終了ｔｅまでの時間ｔ４の間に乳温管理装置内の液体の温度（最高値）が温度Ｔ８を超えているが、温度Ｔ７以下である。かかる場合には洗浄終了ｔｅ時に第１の監視情報Ｌ１が出力される。即ち、洗浄が不完全で、「注意」を要する監視情報が出力される。又、符号ハで示す洗浄例では、洗浄開始ｔｓから洗浄終了ｔｅまでの時間ｔ４の間に乳温管理装置内の液体の温度温度（最高値）が温度Ｔ８以下となっている。かかる場合には洗浄終了ｔｅ時に前記第１の監視情報より緊急度の高い第２の監視情報Ｌ２が出力される。即ち、洗浄が不完全で、「警告」を要する監視情報が出力される。
【００４１】
次に受け入れ監視処理について図４により説明する。符号イ、ロ、ハ、ニは、受け入れ監視処理の例を示すものである。バルククーラー２に生乳を投入（搾乳開始）後、時間ｔ１経過時（例えば搾乳開始から２時間後）において、生乳の温度が温度Ｔ１（図２に示す上限温度ＴＵ１）以上、あるいは前記温度Ｔ１より低い温度Ｔ２（図２に示す下限温度ＴＬ１）以下である場合（第１の受け入れ温度範囲ＴＳ１外）には、第１の監視情報Ｌ１が、前記時間ｔ１経過時に作動監視制御手段６から後述するように出力される。又、バルククーラー２に生乳を投入（搾乳開始）後、時間ｔ１より長い時間ｔ２経過時（例えば搾乳開始から３時間後）において、生乳の温度が前記温度Ｔ１より低い温度Ｔ３（図２に示す上限温度ＴＵ２）以上、あるいは前記温度Ｔ３より低い温度Ｔ４（図２に示す下限温度ＴＬ２）以下である場合（第２の受け入れ温度範囲ＴＳ２外）には、第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が、前記時間ｔ２経過時に作動監視制御手段６から出力される。なお、前記下限温度ＴＬ１と下限温度ＴＬ２とは、等しくてもよい。
【００４２】
例えば、符号イで示す受け入れ監視処理では、バルククーラー２に生乳を投入開始後、時間ｔ１経過時において、生乳の温度が前記温度Ｔ１以上となっていて、第１の受け入れ温度範囲ＴＳ１外である。かかる場合には時間ｔ１経過時に第１の監視情報Ｌ１が出力される。即ち、生乳の温度が「注意」を要する温度になっていて、「注意」を要する監視情報Ｌ１が出力される。又、バルククーラー２に生乳を投入開始後、時間ｔ２経過時において、生乳の温度が前記温度Ｔ３以上となっていて第２の受け入れ温度範囲ＴＳ２外である。かかる場合には時間ｔ２経過時に第２の監視情報Ｌ２が出力される。即ち、生乳の温度が「警告」を要する温度になっていて、「警告」を要する監視情報Ｌ２が出力される。
【００４３】
符号ロで示す受け入れ監視処理では、バルククーラー２に生乳を投入開始後、時間ｔ１経過時において、生乳の温度が前記温度Ｔ１未満であって、温度Ｔ２を超えていて、第１の受け入れ温度範囲ＴＳ１内である。かかる場合には時間ｔ１経過時に監視情報は出力されない。しかし、バルククーラー２に生乳を投入開始後、時間ｔ２経過時において、生乳の温度が前記温度Ｔ３以上となっていて第２の受け入れ温度範囲ＴＳ２外である。かかる場合には時間ｔ２経過時に第２の監視情報Ｌ２が出力される。即ち、生乳の温度が「警告」を要する温度になっていて、「警告」を要する監視情報Ｌ２が出力される。
【００４４】
符号ハで示す受け入れ監視処理では、バルククーラー２に生乳を投入開始後、時間ｔ１経過時において、生乳の温度が前記温度Ｔ１未満であって、温度Ｔ２を超えていて、第１の受け入れ温度範囲ＴＳ１内である。かかる場合には時間ｔ１経過時に監視情報は出力されない。また、バルククーラー２に生乳を投入開始後、時間ｔ２経過時においても、生乳の温度が前記温度Ｔ３未満であって、温度Ｔ４を超えていて、第２の受け入れ温度範囲ＴＳ２内である。かかる場合にも時間ｔ２経過時に監視情報は出力されない。即ち、符号ハで示す受け入れ監視処理におけるバルククーラー２の作動は正常である。
【００４５】
符号ニで示す受け入れ監視処理では、バルククーラー２に生乳を投入開始後、時間ｔ１経過時において、生乳の温度が前記温度Ｔ２以下となっていて、第１の受け入れ温度範囲ＴＳ１外である。かかる場合には時間ｔ１経過時に第１の監視情報Ｌ１が出力される。即ち、生乳の温度が「注意」を要する温度になっていて、「注意」を要する監視情報Ｌ１が出力される。又、バルククーラー２に生乳を投入開始後、時間ｔ２経過時において、生乳の温度が前記温度Ｔ４以下となっていて第２の受け入れ温度範囲ＴＳ２外である。かかる場合には時間ｔ２経過時に第２の監視情報Ｌ２が出力される。即ち、生乳の温度が「警告」を要する温度になっていて、「警告」を要する監視情報Ｌ２が出力される。
【００４６】
次に保冷監視処理について図５により説明する。符号イ、ロ、ハ、ニ、ホ、へは、保冷監視処理の例を示すものである。バルククーラー２に生乳を投入完了後、生乳の温度が温度Ｔ５（図２に示す上限温度ＴＵ３）以上、あるいは前記温度Ｔ５より低い温度Ｔ６（図２に示す下限温度ＴＬ３）以下（保冷温度範囲ＴＳ３外）になった後、時間ｔ３（例えば３０分）経過時に前記該保冷温度範囲ＴＳ３外の時に、監視情報Ｌ２が、時間ｔ３経過時に作動監視制御手段６から後述するように出力される。なお、前記下限温度ＴＬ１と下限温度ＴＬ２と下限温度ＴＬ３とは、等しくてもよい。
【００４７】
例えば、符号イで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ１において、温度Ｔ５以上になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過時の時刻ｔｂ１においても前記温度Ｔ５を超える保冷温度範囲ＴＳ３外である。かかる場合には監視情報Ｌ２が時間ｔ３経過時に作動監視制御手段６から出力される。
【００４８】
符号ロで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ１において温度Ｔ５以上になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過後の時刻ｔｂ１において前記温度Ｔ５未満であり、温度Ｔ６を超える保冷温度範囲ＴＳ３内になった場合である。かかる場合には監視情報Ｌ２は作動監視制御手段６から出力されない。
【００４９】
符号ハで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ２において温度Ｔ６以下になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過後の時刻ｔｂ２において前記温度Ｔ５未満であり温度Ｔ６を超える保冷温度範囲ＴＳ３内である。かかる場合には監視情報Ｌ２は作動監視制御手段６から出力されない。
【００５０】
符号ニで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ２において温度Ｔ６以下になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過後の時刻ｔｂ２において温度Ｔ６以下のまま保冷温度範囲ＴＳ３外である。かかる場合には監視情報Ｌ２が時間ｔ３経過時作動監視制御手段６から出力される。
【００５１】
符号ホで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ１において温度Ｔ５以上になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過後の時刻ｔｂ１において温度Ｔ６以下となり保冷温度範囲ＴＳ３外である。かかる場合には監視情報Ｌ２が作動監視制御手段６から出力される。
【００５２】
符号ヘで示す保冷監視処理では、バルククーラー２に生乳を投入完了後、生乳の温度が、時刻ｔａ２において温度Ｔ６以下になり保冷温度範囲ＴＳ３外になった後、時間ｔ３経過後の時刻ｔｂ２において温度Ｔ５以上となり保冷温度範囲ＴＳ３外である。かかる場合には監視情報Ｌ２が作動監視制御手段６から出力される。
【００５３】
以下、作動監視制御手段６の動作について図６を用いて説明する。なお、バルククーラー２の洗浄、受け入れ、保冷の動作は、バルククーラー制御手段１により周知の方法でなされるものであり、その説明を省略する。前記各監視処理に先立ち、温度測定手段４によりバルククーラー２内及びバルククーラー２が設置されている室内の温度がＡ／Ｄ変換器５によりディジタル信号に変換されている。なお、バルククーラー２内の温度測定手段４は、受け入れ監視処理、保冷監視処理においては、少なくとも１個は生乳の温度を測定するものである。測定された温度データは、作動監視制御手段６内部のデータ格納手段であるＲＡＭに格納される（ステップＳ１）。なお、温度測定手段４は、バルククーラー２内の温度以外に、バルククーラー２が設置されている室内の温度を測定するようにして生乳の管理データとして使用してもよい。また測定された温度データと共に測定された時刻も格納するようにしてもよい。時刻データを得ることにより、障害が発生した時の管理情報として使用できるほか、周知のＨＡＣＣＰシステムに使用することができる。
【００５４】
前記温度データが格納される速度は、監視処理に支障のない速度、例えば、１ポイント／１乃至５分であればよい。かかる場合、搾乳された生乳を２日に１回集乳するものとすると、４８時間分のデータを蓄積できればよく、１つの温度測定手段４について最大２８８０ポイントのデータ格納容量があればよい。この容量は、通常の低価格のデータロガーでも実現できる容量であり、ＲＡＭ容量の少ないパソコンを用いて低価格な乳温管理装置の作動監視装置を実現することができる。
【００５５】
バルククーラー制御手段１が接続されている信号線１ａを介してバルククーラー制御手段１からバルククーラー２の状態、即ち、バルククーラー２の洗浄工程、生乳の受け入れ工程、あるいは生乳の保冷工程の何れかの状態信号が作動監視制御手段６に送信されるものとして説明するが、これ以外に、作動監視制御手段６とバルククーラー制御手段１を接続せず、バルククーラー制御手段１の制御状態に応じて操作者がキーボード８からコマンドを入力し、あるいはファンクションキーを押下して前記作動監視制御プログラムを起動するようにしてもよい。
【００５６】
バルククーラー制御手段１から送信されたバルククーラー２の状態、即ち、バルククーラー２の洗浄工程、生乳の受け入れ工程、あるいは生乳の保冷工程の何れかの状態信号が受信されると、洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムが作動監視制御手段６により実行される。なお、前記ステップＳ１のデータ格納処理は、洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムが実行されると同時に開始するようにしてもよい。また、前記洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムは、それぞれ単独に実行できるようにしてもよく、あるいは、洗浄監視処理と、複数回の受け入れ監視処理及び保冷監視処理を連続して実行するようにしてもよい。
【００５７】
まず、洗浄監視処理について説明する。なお、上記のようなバルククーラー２を用いた乳温管理装置は、洗浄工程においては、通常水洗工程、アルカリ洗浄工程、酸洗浄工程、殺菌工程があり、各工程において、所定の処理がなされる。通常、通常水洗、アルカリ洗浄、殺菌は毎回行われ、酸洗浄は、アルカリ洗浄２乃至３回程度に１回の頻度でアルカリ洗浄後に行なわれる。以下、洗浄時の工程における作動を監視する洗浄監視処理及び監視方法の説明では、前記アルカリ洗浄について説明するが、酸洗浄工程についても投入される液体が酸性液である点を除き、アルカリ洗浄同様の監視処理であるので、酸洗浄については説明を省略する。また、通常水洗工程、殺菌工程での処理については、監視処理はなされない。洗浄監視処理では、まずステップＳ５において、洗浄の終了を判定する。かかる判定は、状態信号を判別して洗浄が終了するまで待つようにしてもよく、あるいは、予め洗浄時間が予め分っている場合には、作動監視制御手段６内のタイマーで洗浄時間ｔ４を監視してもよい。
【００５８】
洗浄が終了するとステップＳ６に進み、それまでＲＡＭに格納した洗浄時のバルククーラー２内の液体の温度を判別する。該判別処理は、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のようになされる。即ち、ＲＯＭ内に格納されている、図２に示したような判別条件（監視時間欄、監視温度欄及び監視情報欄の（ｔ４）、（ＴＵ、ＴＬ）の作動監視データと、それまでＲＡＭに格納した洗浄時のバルククーラー２内の温度データとが逐次比較される。あるいは、洗浄時のバルククーラー２内の温度をＲＡＭに格納する時に、既に格納されている温度データと比較して、常に最高温度のみをＲＡＭ内に保持するようにしてもよい。かかる場合には、ＲＡＭ容量が低減できる。作動監視制御手段６の処理負担が少ない洗浄時には常に最高温度のみを検出するプログラムを実行しても処理速度の低減にはならない。あるいは、前記比較処理プログラムの実行は、ＲＡＭにデータが格納される毎に逐次実行するようにしてもよい。かかる場合には洗浄の終了と同時に結果が得られ、障害の発生の感知が迅速にできる。
【００５９】
前記比較処理プログラムにより、洗浄開始から、終了までの間のバルククーラー２内の液体の温度データが、予め定められた温度Ｔ７（上限温度）を超えているか、温度Ｔ７以下であって温度Ｔ８（下限温度）を超えているか、あるいは温度Ｔ８以下であるかを判定する。そしてステップＳ７に進み、温度Ｔ７を超えている場合には洗浄が正常である情報がＲＡＭに格納され、受け入れ監視処理に戻る。温度Ｔ７以下であって温度Ｔ８を超えている場合には第１の監視情報「注意」が作成され、温度Ｔ８以下の場合には第２の監視情報「警告」が作成されて、それぞれＲＡＭに格納されて、ステップＳ２５に進む。
【００６０】
また、ステップＳ２５以下の処理は、当該洗浄監視処理以外の、受け入れ監視処理、保冷処理にも共通に使用される。ステップＳ２５において、前記監視情報を携帯電話機１１に送信するにあたり、送信回数をゼロにして、ステップＳ２６で待機タイマーをセットする。該待機タイマーは、前記第１の監視情報又は第２の監視情報を携帯電話機１１に送信後、所定の時間経過しても前記第１の監視情報又は第２の監視情報が消去されない時に、再度、前記第１の監視情報又は第２の監視情報を携帯電話機１１に送信するためのタイマーであって、例えば５分間の待機時間を設定する。該再送信は、作動監視制御手段６内の再送信プログラム（再送信手段）で以下のようになされる。
【００６１】
即ち、ステップＳ２６からステップＳ２７に進み、該ステップＳ２７において、前記作成された第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報を携帯電話機１１に周知の電子メールで送信し、前記待機タイマーをスタートする。ステップＳ２８では前記待機タイマーがタイムアップしたかを監視し、所定の待機時間が経過した場合ステップＳ２９に進む。ステップＳ２９では、第１の監視情報又は第２の監視情報を送信後の携帯電話機１１からの応答を監視する。そして携帯電話機１１から応答があった場合には前記第１の監視情報又は第２の監視情報が消去される。ここで、携帯電話機１１からの応答とは、前記ステップ２７にて送信された電子メールを酪農家が見たことを作動監視制御手段６に通知するものである。かかる通知は、携帯電話機１１から送信された電子メールを解読するプログラムを作動監視制御手段６に格納し、このプログラムの実行により電子メールで送信された第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報の内容を解読し、酪農家からの通知であると判断するようにしてもよい。あるいは、携帯電話機１１から応答せずに、作動監視制御手段６のキーボードあるいは、ファンクションキーを押下して電子メールを見たことを作動監視制御手段６に入力するようにしてもよい。
【００６２】
ステップ２９において前記第１の監視情報又は第２の監視情報が消去されていない場合には、ステップＳ３０に進み、消去されている場合には受け入れ監視処理に戻る。ステップＳ３０では、前記携帯電話機１１に送信した回数を＋１し、ステップＳ２６に戻る。なお、前記ステップＳ３０において、予め定められた送信回数に達した場合、あるいは、送信回数に関係なくステップ２７において監視情報を送信するときに、作動監視制御手段６によって図示していないサイレン、ブザー等の音により、あるいはランプなどで異常であることを報知するようにしてもよい。また、送信回数は、同一として管理してもよく、あるいは第１の監視情報と第２の監視情報それぞれ別に管理してもよい。
【００６３】
次に、受け入れ監視処理について説明する。該受け入れ監視処理において、作動監視制御手段６により、ステップＳ８でタイマー１及びタイマー２を予め定められた値、例えば図２で示した監視時間ｔ１（２時間）、ｔ２（３時間）がＲＯＭから読み出され、それぞれタイマーに設定される。バルククーラー２に生乳を投入開始後にステップＳ９で前記タイマー１及びタイマー２がスタートされる。ステップＳ１０において作動監視制御手段６は、タイマー１のタイムアップを監視し、所定の監視時間ｔ１に達するとステップＳ１１に進み、その時におけるバルククーラー２内の生乳の温度が、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のように比較される。
【００６４】
即ち、ステップＳ１１では、生乳を投入開始後の第１の時間（監視時間ｔ１）経過時に、作動監視制御手段６により、図２で示した温度ＴＵ１と温度ＴＬ１がＲＯＭから、また監視時間ｔ１経過時の生乳の温度データがＲＡＭから、それぞれ読み出される。比較処理プログラムにより、監視時間ｔ１経過時の生乳の温度が、前記温度ＴＵ１未満であって前記温度ＴＵ１より低い温度ＴＬ１超える第１の受け入れ温度範囲ＴＳ１内であるか範囲外であるかが判定される。生乳の温度が前記第１の受け入れ温度範囲ＴＳ１外の時には、ステップＳ１２に進み第１の監視情報が作成され、生乳の温度が前記第１の受け入れ温度範囲ＴＳ１内の時には監視情報は作成されず正常である情報が、それぞれの結果をＲＡＭに格納され、それぞれステップＳ１３に進む。
【００６５】
ステップＳ１３では、前記監視情報の有無を判断し、第１の監視情報が作成されている場合には、ステップＳ１５で該第１の監視情報、送信時刻、監視処理の種別が携帯電話機１１に周知の電子メールで送信されステップＳ１４に進む。また、第１の監視情報が作成されていない場合には、ステップＳ１４に進む。
【００６６】
作動監視制御手段６は、ステップＳ１４でタイマー２のタイムアップを監視し、所定の監視時間ｔ２に達するとステップＳ１６に進み、その時におけるバルククーラー２内の生乳の温度が、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のように比較される。即ち、ステップＳ１６では、生乳を投入開始後の第２の時間（監視時間ｔ２）経過時に、作動監視制御手段６により、図２で示した温度ＴＵ２と温度ＴＬ２がＲＯＭから、また監視時間ｔ２経過時の生乳の温度データがＲＡＭから、それぞれ読み出される。比較処理プログラムにより監視時間ｔ２経過時の生乳の温度が前記温度ＴＵ２未満であって前記温度ＴＵ２より低い温度ＴＬ２を超える第２の受け入れ温度範囲ＴＳ２内であるか範囲外であるかが判定される。生乳の温度が前記第２の受け入れ温度範囲ＴＳ２内の時には監視情報は作成されず正常である情報がＲＡＭに格納され、受け入れ監視処理を終了する。生乳の温度が前記第２の受け入れ温度範囲ＴＳ２外の時にはステップＳ１７に進み、第２の監視情報が作成されてＲＡＭに格納される。そして前記洗浄監視処理で述べたと同様にして、ステップＳ２５以降の処理がなされる。但し、ステップＳ２７では第１の監視情報は送信されない。
【００６７】
次に、保冷監視処理について説明する。該保冷監視処理は、前記受け入れ監視処理が終了すると同時に開始される。該保冷監視処理において、作動監視制御手段６により、ステップＳ１８でタイマー３を予め定められた値、例えば図２で示した監視時間ｔ３（３０分）がＲＯＭから読み出され、タイマー３に設定されると共に、図２で示した温度ＴＵ３と温度ＴＬ３がＲＯＭから読み出される。ステップＳ１９では、バルククーラー２に生乳を投入完了後の生乳の温度データがＲＡＭから逐次読み出され、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のように比較される。即ち、生乳を投入完了後、比較処理プログラムにより生乳の温度が前記温度ＴＵ３未満であって前記温度ＴＵ３より低い温度ＴＬ３を超える第３の受け入れ温度範囲ＴＳ３内であるか範囲外であるかが判定される。生乳の温度が前記第３の受け入れ温度範囲ＴＳ３外の時には、ステップＳ２０に進み、生乳の温度が前記第３の受け入れ温度範囲ＴＳ３内の時にはステップＳ１９に戻り生乳の温度が監視される。
【００６８】
ステップＳ２０では、前記タイマー３がスタートされる。ステップＳ２１において作動監視制御手段６は、タイマー３のタイムアップを監視し、前記所定の監視時間ｔ３に達するとステップＳ２２に進み、その時におけるバルククーラー２内の生乳の温度が、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のように比較される。即ち、生乳を投入完了後、前記監視時間ｔ３経過時の生乳の温度が前記温度ＴＵ３未満であって前記温度ＴＵ３より低い温度ＴＬ３を超える第３の受け入れ温度範囲ＴＳ３内であるか範囲外であるかが判定される。生乳の温度が前記第３の受け入れ温度範囲ＴＳ３外の時には、ステップＳ２３に進み、第２の監視情報が作成された後に、ステップＳ２５に進む。生乳の温度が前記第３の受け入れ温度範囲ＴＳ３内の時には監視情報は作成されず正常である情報が作成され、それぞれＲＡＭに格納され、ステップＳ２４において前記タイマ３はクリアされ、ステップＳ１８に戻る。第２の監視情報が作成され、ステップＳ２５に進んだ場合には前記洗浄監視処理で述べたと同様にして、ステップＳ２５以降の処理がなされる。なお、タイマー３のタイムアップ以前に生乳の温度が前記第３の受け入れ温度範囲ＴＳ３内となった場合に、前記タイマー３をクリアするようにしてもよい。かかる場合には、タイマー３のスタート開始以降、生乳の温度を監視する処理を付加する。
【００６９】
以下、第１の実施形態におけるバルククーラー２の洗浄工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６によりバルククーラー２の洗浄工程において、その作動が以下のようにして監視される。該洗浄監視工程では、洗浄開始から終了までの間、温度測定手段４により得られたバルククーラー２内の液体の温度データが作動監視制御手段６のＲＡＭに格納される。そして該作動監視制御手段６により、洗浄終了時においてＲＯＭに予め格納されている監視温度データと前記温度測定手段４により得た、ＲＡＭに格納されている洗浄中のバルククーラー２内の液体の温度データ（あるいは最高温度）とが比較手段により比較される。該比較結果が、温度ＴＵ以下であって、温度ＴＵより低い温度ＴＬを超えている場合には第１の監視情報が、前記温度ＴＬ以下の場合には前記第１の監視情報より緊急度の高い第２の監視情報が作成される。そして第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報が携帯電話機１１に電子メールで送信されてバルククーラー２の洗浄工程における作動が監視される。
【００７０】
次に、第１の実施形態におけるバルククーラー２の受け入れ監視工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６により受け入れ監視工程において、その作動は以下のようにして監視される。該受け入れ監視工程では、バルククーラー２に生乳を投入開始後、バルククーラー２内の生乳の温度データが作動監視制御手段６のＲＡＭに格納される。また、バルククーラー２に生乳を投入開始後、タイマー監視が開始され、該タイマーが第１の時間ｔ１を経過した時バルククーラー２内の生乳の温度が測定される。該タイマーが第１の時間ｔ１を経過した時における生乳の温度データと前記ＲＯＭ内の監視温度データとが比較手段で比較される。該比較結果が、前記温度ＴＵ１未満であって前記温度ＴＵ１より低い温度ＴＬ１を超える第１の受け入れ温度範囲ＴＳ１内であるか範囲外であるかを検出する。その結果、前記第１の受け入れ温度範囲外となった時に第１の監視情報が作成されＲＡＭに格納される。
【００７１】
第１の監視情報が作成されている場合には、第１の監視情報と共に、送信回数、送信時の時刻、監視処理の種別が含まれている情報が携帯電話機１１に送信される。その後、前記バルククーラー２に生乳を投入開始後に開始されたタイマーが、第１の時間ｔ１より長い第２の時間ｔ２を経過した時、バルククーラー２内の生乳の温度が測定される。該第２の時間ｔ２を経過した時における生乳の温度データと前記ＲＯＭ内の監視温度データとが比較手段で比較される。該比較結果が、前記温度ＴＵ２未満であって前記温度ＴＵ２より低い温度ＴＬ２を超える第２の受け入れ温度範囲ＴＳ２内であるか範囲外であるかを検出する。その結果、前記第２の受け入れ温度範囲外となった時に前記第１の監視情報より緊急度の高い第２の監視情報が作成されてＲＡＭに格納される。そして第２の監視情報と共に、送信時刻、送信回数、監視処理の種別が携帯電話機１１に送信されてバルククーラー２の受け入れ監視工程における作動が監視される。
【００７２】
次に、第１の実施形態におけるバルククーラー２の保冷監視工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６により保冷監視工程において、その作動は以下のようにして監視される。該保冷監視工程では、バルククーラー２に生乳を投入完了後、バルククーラー２内の生乳の温度データがＲＡＭに格納されると共にＲＯＭ内の監視温度データとバルククーラー２内の生乳の温度データとが比較手段で比較される。該比較結果が、温度ＴＵ３未満であって、前記温度ＴＵ３より低い温度ＴＬ３を超える保冷温度範囲ＴＳ３内であるか範囲外であるかを検出する。その結果、前記保冷温度範囲ＴＳ３外になった時にタイマー監視を開始する。該タイマーが第３の時間ｔ３を経過した時、バルククーラー２内の生乳の温度が測定され、前記保冷温度範囲ＴＳ３外の時に、監視情報が作成されＲＡＭに格納される。そして監視情報と共に、送信時刻、送信回数、監視処理の種別が携帯電話機１１に送信されてバルククーラー２の保冷監視工程における作動が監視される。前記監視情報が作成されない場合にはタイマーはクリアされ、ＲＯＭ内の監視温度データとバルククーラー２内の生乳の温度とが比較手段で比較される処理が続行される。
【００７３】
なお、工場及び／または検査機関１３には、ＲＡＭに格納された各種監視処理時の室温、乳温、洗浄時のバルククーラー２内の液体の温度、携帯電話機１１への送信履歴等を送信し、生乳の管理情報として用いるようにしてもよい。その結果、本発明の乳温管理装置の作動監視装置及びその監視方法は、周知のＨＡＣＣＰシステムに適用することができる。
【００７４】
次に、前記実施形態の構成により実施される第２の実施形態について説明する。第２の実施形態は、洗浄監視処理、受け入れ監視処理、保冷監視処理、環境監視処理の各処理の間中、いつでも第１の監視情報又は第２の監視情報を発するものである。即ち、洗浄監視処理では、洗浄開始後から洗浄終了時までの間、液温（洗浄液及び排液の温度）を監視し、液温が所定の温度範囲外となる異常が発生した場合に、直ちに第１の監視情報か、第２の監視情報を通信端末に送信する。また、受け入れ監視処理では、初回受け入れと、次回以降の受け入れとで異なる監視処理を行い、生乳を投入開始後、生乳の温度が所定の温度範囲外となった場合に、直ちに第１の監視情報か、第２の監視情報を通信端末に送信する。更に、保冷監視処理及びバルククーラーが設置されている室内温度を監視する環境監視処理では、生乳の温度および室内温度が所定の温度範囲外となった場合に、直ちに第１の監視情報か、第２の監視情報をいつでも通信端末に送信する。何れの場合の処理でも作動監視制御手段６には、温度測定手段４から得たデータが、データ格納手段の一つであるＲＡＭに格納されているようにするのが望ましい。
【００７５】
第２の実施形態における作動監視制御手段６で使用するデータ構造を図７により説明する。前記作動監視制御手段６のＲＯＭに格納されている監視時間欄、監視温度欄及び監視情報欄の（ｔ１乃至ｔ４）、（ＴＵ、ＴＬ、ＴＦ、ＴＳ、ＴＯ）及び監視情報からなる作動監視データ（第１の情報、第２の情報）は、処理欄に示す洗浄監視処理、受け入れ監視処理、保冷監視処理、環境監視処理で使用される。監視情報欄のＴＯは、測定対象温度である。また、監視時間（ｔ１乃至ｔ４）、監視温度（ＴＵ、ＴＬ、ＴＦ、ＴＳ）及び監視情報に括弧内に付加されて記述されている値、あるいは監視情報の表し方は、一例であって、これ以外の値あるいは表し方であってもよい。また、監視情報は、第１の監視情報と第２の監視情報とがあり、第２の監視情報は、第１の監視情報より緊急度の高い情報である。即ち、酪農家が重大な損害を被る可能性のある障害が発生したことを示し、通信端末１１（以下、携帯電話機として説明する。）に電子メールを送信する時に、第１の監視情報と第２の監視情報とを、例えば「注意」、「警告」などの具体的な情報で表す。なお、次回受け入れ処理において、搾乳回数が多い場合には、第３の時間ｔ３以降に、第４の時間ｔ４を設けてもよく、係る場合には、例えば前記第３の時間ｔ３と同様な時間を設定してもよく、あるいは、それ以外の時間を設定してもよい。また、図８乃至図１０の第１の監視情報Ｌ１が出力されたのち、該第１の監視情報Ｌ１が消去されていなくとも、第２の監視情報Ｌ２が出力される条件が成立した場合には、第１の監視情報Ｌ１を消去して第２の監視情報Ｌ２が出力される。
【００７６】
第２の実施形態における発明の理解を容易にするために図８乃至図１０を用いて前記洗浄監視処理、受け入れ監視処理、保冷監視処理、環境監視処理の各処理における監視情報を得る方法について以下に説明する。図８乃至図１０において、横軸は時間を、縦軸は乳温管理装置内の生乳あるいは液体の温度を表し、第１の監視情報と第２の監視情報を、それぞれＬ１、Ｌ２で表す。また、洗浄監視処理の処理開始時におけるバルククーラー２内の液体の温度をＴｂ、受け入れ監視処理及び保冷監視処理の処理開始時における生乳の温度をＴＳ０で表す。
【００７７】
まず、洗浄監視処理について図８により説明する。符号イ、ロ、ハ、ニは、洗浄監視処理ＰＳ１（図１２参照）の例を示すものである。洗浄開始ｔｓから洗浄終了ｔｅまでの間にバルククーラー２内の液温が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超える場合には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。又、洗浄開始ｔｓから洗浄終了ｔｅまでの間に液温が下限温度ＴＬ以下である場合には、第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。ここで、液温は、洗浄液と排液とがそれぞれ独立に監視され、該洗浄液と排液には上限温度と下限温度がそれぞれ定められており、前記洗浄液と排液とは、前記それぞれの上限温度と下限温度とにより、それぞれ独立した第１の監視情報と第２の監視情報が出力される。図８においては、洗浄液の監視処理として説明し、排液の監視処理は、監視温度が異なるのみで、その他は同一であり、その説明を省略する。前記洗浄液と排液は、洗浄開始時には両液の温度が低い場合がある。かかる場合には図８で示すように、洗浄開始ｔｓから一定時間ｔｈだけ洗浄監視処理の開始を遅らせるようにプログラムしてもよい。
【００７８】
図８において、符号イで示す洗浄例では、洗浄開始ｔｓから点Ｐ０で示す時刻まで洗浄液の温度が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超えている。一定時間ｔｈ迄は、前記のように洗浄監視処理はなされず、監視情報は出力されない。一定時間ｔｈから点Ｐ０で示す時刻までの間は前記条件が成立しており、一定時間ｔｈにおいて第１の監視情報Ｌ１が直ちに出力される。即ち、洗浄が不完全で、「注意」を要する監視情報が出力される。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。そして点Ｐ０で示す時刻から洗浄終了ｔｅまでの間は上限温度ＴＵを超えているので第１の監視情報Ｌ１及び第２の監視情報Ｌ２何れも出力されない。
【００７９】
符号ロで示す洗浄例では、洗浄開始ｔｓから洗浄終了ｔｅまでの間、洗浄液の温度が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超えている。かかる場合、一定時間ｔｈにおいて第１の監視情報Ｌ１が直ちに出力される。即ち、洗浄が不完全で、「注意」を要する監視情報が出力される。一度監視情報が出力されると、前記同様に所定時間が経過するまで同一の監視情報は出力されない。前記所定時間が経過するまでに送信された前記監視情報が消去されていない場合には再度同一の監視情報が送信される。
【００８０】
符号ハで示す洗浄例では、洗浄開始ｔｓから点Ｐ２で示す時刻まで洗浄液の温度が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超えている。一定時間ｔｈ迄は、前記のように洗浄監視処理はなされず、監視情報は出力されない。一定時間ｔｈから点Ｐ２で示す時刻までの間は前記条件が成立しており、一定時間ｔｈにおいて第１の監視情報Ｌ１が直ちに出力される。即ち、洗浄が不完全で、「注意」を要する監視情報が出力される。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。また、点Ｐ２で示す時刻から点Ｐ３で示す時刻までの間は、洗浄液の温度が下限温度ＴＬ以下となっている。かかる場合、点Ｐ２で示す時刻において第２の監視情報Ｌ２が直ちに出力される。即ち、洗浄が不完全で、「警告」を要する監視情報が出力される。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。更に、点Ｐ３で示す時刻から洗浄終了ｔｅまでの間は、洗浄液の温度が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超えている。かかる場合、点Ｐ３で示す時刻において第１の監視情報Ｌ１が直ちに出力される。
【００８１】
符号ニで示す洗浄例では、洗浄開始ｔｓから点Ｐ１で示す時刻まで洗浄液の温度が上限温度ＴＵ以下であって、該上限温度ＴＵより低い下限温度ＴＬを超えている。一定時間ｔｈ迄は、前記のように洗浄監視処理はなされず、監視情報は出力されない。点Ｐ１で示す時刻は、一定時間ｔｈ以前であり、一定時間ｔｈから洗浄終了ｔｅまでの間は上限温度ＴＵを超えているので第１の監視情報Ｌ１及び第２の監視情報Ｌ２何れも出力されない。
【００８２】
次に受け入れ監視処理について図９により説明する。符号イは受け入れ監視処理ＰＳ２（図１２参照）の例を示すものである。初回の搾乳ＰＳ２１での受け入れ監視処理と次回の搾乳ＰＳ２２での受け入れ監視処理とは、監視時間、監視温度、監視回数が図７に示すように異なるのみで、その処理は同一であり、初回の搾乳ＰＳ２１の受け入れ監視処理を符号ＰＳ２として説明し、次回の搾乳ＰＳ２２についての受け入れ監視処理については、その説明を省略する。
【００８３】
バルククーラー２に生乳を投入開始後（搾乳開始時刻ｔｓ）から搾乳が終了する時刻ｔ１迄の第１の時間が経過するまで（乳牛の数によって異なる）に、生乳の温度が上限温度ＴＵ１未満であって該上限温度ＴＵ１より低い第１の温度ＴＦ１以上、あるいは下限温度ＴＬ１を超え、かつ該下限温度ＴＬ１より高い第２の温度ＴＳ１以下の時には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、生乳の温度が上限温度ＴＵ１以上、あるいは下限温度ＴＬ１以下の時には、前記第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。なお、前記下限温度ＴＬ１と第２の温度ＴＳ１とは、等しくてもよい。また、搾乳終了時には、キーボード８等から搾乳終了を入力するようにしてもよく、または予め酪農家の規模に応じて設定するようにしておいてもよい。
【００８４】
同様にして、搾乳終了時刻ｔ１から時刻ｔ２迄の第２の時間（例えば３０分）が経過するまでに、生乳の温度が上限温度ＴＵ２未満であって該上限温度ＴＵ２より低い第１の温度ＴＦ２以上、あるいは下限温度ＴＬ２を超え、かつ該下限温度ＴＬ２より高い第２の温度ＴＳ２以下の時には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、生乳の温度が上限温度ＴＵ２以上あるいは下限温度ＴＬ２以下の時には、前記第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。なお、前記下限温度ＴＬ２と第２の温度ＴＳ２とは、等しくてもよい。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。
【００８５】
同様にして、時刻ｔ２から時刻ｔ３迄の第３の時間（例えば３０分）が経過するまでに、生乳の温度が上限温度ＴＵ３未満であって該上限温度ＴＵ３より低い第１の温度ＴＦ３以上、あるいは下限温度ＴＬ３を超え、かつ該下限温度ＴＬ３より高い第２の温度ＴＳ３以下の時には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、生乳の温度が上限温度ＴＵ３以上、あるいは下限温度ＴＬ３以下の時には、前記第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。なお、前記下限温度ＴＬ３と第２の温度ＴＳ３とは、等しくてもよい。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。
【００８６】
同様にして、時刻ｔ３から時刻ｔ４迄の第４の時間（例えば６０分）が経過するまでに、生乳の温度が上限温度ＴＵ４未満であって該上限温度ＴＵ４より低い第１の温度ＴＦ４以上、あるいは下限温度ＴＬ４を超え、かつ該下限温度ＴＬ４より高い第２の温度ＴＳ４以下の時には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、生乳の温度が上限温度ＴＵ４以上、あるいは下限温度ＴＬ４以下の時には、前記第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。なお、前記下限温度ＴＬ４と第２の温度ＴＳ４とは、等しくてもよい。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。時刻ｔ４以降は、保冷処理ＰＳ３（図１２参照）が開始される。
【００８７】
例えば、符号イで示す受け入れ監視処理では、（搾乳開始時刻ｔｓ）から時刻ｔ４の第４の時間が経過するまで以下のような処理がなされる。即ち、第１の時間経過内で予め定められた上限温度ＴＵ１、下限温度ＴＬ１、第１の温度ＴＦ１、第２の温度ＴＳ１を参照して、生乳の温度が前記温度のどこにあるか比較される。図９においては、生乳の温度は、搾乳開始時刻ｔｓから点Ｐ０で示す時刻まで上限温度ＴＵ１以上である。かかる場合には搾乳開始時刻ｔｓに第２の監視情報Ｌ２が直ちに出力される。また、搾乳開始時刻ｔｓには酪農家がバルククーラー２の傍にいて監視している場合が多く、かかる場合には、搾乳開始直後の前記第２の監視情報Ｌ２は出力しないようにしてもよい。かかる処理は、前記洗浄処理同様に、受け入れ監視処理の開始を遅らせるようにプログラムしてもよい。
【００８８】
点Ｐ０で示す時刻から点Ｐ１で示す時刻までは、生乳の温度は、上限温度ＴＵ１未満であるが第１の温度ＴＦ１以上である。かかる場合には点Ｐ０で示す時刻に第１の監視情報Ｌ１が直ちに出力される。さらに点Ｐ１で示す時刻から点Ｐ２で示す時刻までは、生乳の温度は、第１の温度ＴＦ１未満であって、第２の温度ＴＳ１を超えている。かかる場合には監視情報は出力されない。しかし、点Ｐ２で示す時刻から点Ｐ３で示す時刻までは、生乳の温度は、第２の温度ＴＳ１以下であるが下限温度ＴＬ１を超えている。かかる場合には点Ｐ２で示す時刻に第１の監視情報Ｌ１が直ちに出力される。そして点Ｐ３で示す時刻から時刻ｔ１までは、生乳の温度は、下限温度ＴＬ１以下である。かかる場合には点Ｐ３で示す時刻に第２の監視情報Ｌ２が直ちに出力される。前記何れの場合においても一度監視情報が出力されると、所定時間（例えば５分）が経過するまで同一の監視情報は出力されない。以下同様にして、第２の時間、第３の時間、第４の時間が経過するまで、それぞれの時間内において定められた上限温度ＴＵｎ、下限温度ＴＬｎ、第１の温度ＴＦｎ、第２の温度ＴＳｎを参照して、生乳の温度が前記温度のどこにあるか比較される。但し、ｎ＝２、３、４である。
【００８９】
次に保冷監視処理ＰＳ３（図１２参照）について図１０により説明する。符号イ、ロ、ハは、保冷監視処理の例を示すものである。初回または次回以降の受け入れ処理後の時刻ｔｓから、次回受け入れ処理または集乳が開始される時刻ｔｅまでの間に、生乳の温度が上限温度ＴＵ未満であって該上限温度ＴＵより低い第１の温度ＴＦ以上、あるいは下限温度ＴＬを超え、かつ該下限温度ＴＬより高い第２の温度ＴＳ以下の時には、第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、生乳の温度が上限温度ＴＵ以上、あるいは下限温度ＴＬ以下の時には、前記第１の監視情報Ｌ１より緊急度の高い第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。一度監視情報が出力されると、所定時間が経過するまで同一の監視情報は出力されない。なお、前記下限温度ＴＬと第２の温度ＴＳとは、等しくてもよい。
【００９０】
例えば、符号イで示す保冷監視処理では、前記初回または次回以降の受け入れ処理後の時刻ｔｓ後、生乳の温度が、点Ｐ０で示す時刻に、前記上限温度ＴＵ未満であって該上限温度ＴＵより低い第１の温度ＴＦ以上となり、その後、点Ｐ１で示す時刻に上限温度ＴＵ以上になり、時刻ｔｅで次回受け入れ処理または集乳が開始されるものである。かかる場合、点Ｐ０で示す時刻に第１の監視情報得Ｌ１が直ちに作動監視制御手段６から出力される。また、点Ｐ１で示す時刻に第２の監視情報得Ｌ２が直ちに作動監視制御手段６から出力される。前記何れの場合においても一度監視情報が出力されると、所定時間（例えば５分）が経過するまで同一の監視情報は出力されない。
【００９１】
符号ロで示す保冷監視処理では、前記初回または次回以降の受け入れ処理後の時刻ｔｓ後、次回受け入れ処理または集乳が開始されるまで、生乳の温度は、前記第１の温度ＴＦ未満であって、第２の温度ＴＳを超えているので監視情報は作動監視制御手段６から出力されない。
【００９２】
符号ハで示す保冷監視処理では、前記初回または次回以降の受け入れ処理後の時刻ｔｓ後、生乳の温度は点Ｐ２で示す時刻に前記第２の温度ＴＳ以下であって前記下限温度ＴＬを超えており、その後、点Ｐ３で示す時刻に下限温度ＴＬ以下になり、時刻ｔｅで次回受け入れ処理または集乳が開始されるものである。かかる場合、点Ｐ２で示す時刻に第１の監視情報Ｌ１が直ちに作動監視制御手段６から出力される。また、点Ｐ３で示す時刻に第２の監視情報Ｌ２が直ちに作動監視制御手段６から出力される。前記何れの場合においても一度監視情報が出力されると、所定時間（例えば５分）が経過するまで同一の監視情報は出力されない。
【００９３】
環境監視処理は、前記保冷処理のように、初回または次回以降の受け入れ処理後から次回受け入れ処理または集乳が開始される時刻ｔｅまでの間の処理が監視されるものではなく、常時監視されるものである。前記保冷処理とは、監視時間と監視温度が図７に示すように異なるのみで、判定処理は同様であり、その説明を省略する。
【００９４】
以下、作動監視制御手段６の動作について図１１を用いて説明する。なお、バルククーラー２の洗浄、受け入れ、保冷の動作は、バルククーラー制御手段１により周知の方法でなされるものであり、その説明を省略する。前記各監視処理に先立ち、温度測定手段４により、バルククーラー２内の洗浄液、排液、生乳の温度、及びバルククーラー２が設置されている室内の温度がＡ／Ｄ変換器５によりディジタル信号に変換されている。なお、温度測定手段４は、洗浄処理において洗浄液、排液の温度をそれぞれ測定し、受け入れ監視処理、保冷監視処理において生乳の温度を測定し、また環境監視処理においてバルククーラー２が設置されている室内の温度を測定する。
【００９５】
測定された前記温度データは、作動監視制御手段６内部のデータ格納手段であるＲＡＭに格納される（ステップＳ１）。測定された温度データと共に測定された時刻も格納するようにしてもよい。時刻データを得ることにより、障害が発生した時の管理情報として使用できるほか、周知のＨＡＣＣＰシステムに使用することができる。前記温度データが格納される速度は、監視処理に支障のない速度、例えば、１ポイント／１乃至５分であればよい。かかる場合、集乳された生乳を２日に１回収集するものとすると、４８時間分のデータを蓄積できればよく、１つの温度測定手段４について最大２８８０ポイントのデータ格納容量があればよい。この容量は、通常の低価格のデータロガーでも実現できる容量であり、ＲＡＭ容量の少ないパソコンを用いて低価格な乳温管理装置の作動監視装置を実現することができる。
【００９６】
バルククーラー制御手段１が接続されている信号線１ａを介してバルククーラー制御手段１からバルククーラー２の状態、即ち、バルククーラー２の洗浄工程、生乳の受け入れ工程、あるいは生乳の保冷工程の何れかの状態信号が作動監視制御手段６に送信されるものとして説明するが、これ以外に、作動監視制御手段６とバルククーラー制御手段１を接続せず、バルククーラー制御手段１の制御状態に応じて操作者がキーボード８からコマンドを入力し、あるいはファンクションキーを押下して前記作動監視制御プログラムを起動するようにしてもよい。
【００９７】
バルククーラー制御手段１から送信されたバルククーラー２の状態、即ち、バルククーラー２の洗浄工程、生乳の受け入れ工程、あるいは生乳の保冷工程の何れかの状態信号が受信されると、洗浄監視処理、受け入れ監視処理、保冷監視処理、環境監視処理の各処理プログラムが作動監視制御手段６により実行される。なお、前記ステップＳ１のデータ格納処理は、洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムが実行されると同時に開始するようにしてもよい。また、前記洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムは、それぞれ単独に実行できるようにしてもよく、あるいは、洗浄監視処理と、複数回の受け入れ監視処理及び保冷監視処理を連続して実行するようにしてもよい。さらに、環境監視処理は、前記各処理と平行してなされるようにマルチタスク処理されることが望ましく、又、バルククーラー制御手段１から送信されたバルククーラー２の状態に応じて開始される洗浄監視処理、受け入れ監視処理、保冷監視処理の各処理プログラムとは独立して、常時作動しているようにしてもよい。
【００９８】
まず、洗浄監視処理について説明する。なお、上記のようなバルククーラー２を用いた乳温管理装置は、洗浄工程においては、通常、集乳後にぬるま湯洗浄（水洗工程）、アルカリ洗浄（アルカリ洗浄工程）及び酸洗浄（酸洗浄工程）、すすぎ、殺菌剤循環（殺菌工程）がなされ、前記各工程において、所定の処理がなされる。通常、通常水洗、アルカリ洗浄は毎回行われ、酸洗浄はアルカリ洗浄２乃至３回毎に１回の頻度でアルカリ洗浄後に行なわれることが多い。以下洗浄監視処理及び、洗浄工程における作動を監視する、作動監視方法の説明では、前記アルカリ洗浄について説明するが、酸洗浄工程についても投入される液が酸性液である点を除き、アルカリ洗浄同様の監視処理であるので、酸洗浄については説明を省略する。また、通常水洗工程、殺菌工程での処理については、監視処理はなされない。洗浄監視処理では、まずステップＳ５において、洗浄の終了を判定する。かかる判定は、状態信号を判別して洗浄が終了するまで待つようにしてもよく、あるいは、洗浄時間が予め分っている場合には、作動監視制御手段６内のタイマーで洗浄時間ｔ４を監視してもよい。
【００９９】
洗浄が終了していない場合にはステップＳ６に進み、乳温管理装置内の洗浄液と排液の温度を測定し、該温度をそれぞれ定められた上限温度と下限温度とにより判定し、それぞれ独立した第１の監視情報と第２の監視情報が後述するように出力される。該データの判別処理は、作動監視制御手段６内の比較処理プログラム（比較手段）で以下のようになされる。即ち、ＲＯＭ内に格納されている、図７に示したような判別条件（監視時間欄、監視温度欄及び監視情報欄の（ｔ４）、（ＴＵ、ＴＬ））の作動監視データと、前記乳温管理装置内の洗浄液と排液の温度データとが逐次比較される。温度データが逐次比較される結果、該温度データをＲＡＭに格納しなくてもよく、かかる場合にはＲＡＭ容量が低減できる。なお、後日の管理データとして該温度データをＲＡＭに格納してもよい。また、温度データが逐次比較されることによって、洗浄液と排液の温度がすぐに得られ、洗浄時の障害の発生が迅速に感知できる。
【０１００】
前記比較処理プログラムにより、洗浄開始から、終了までの間、洗浄液と排液の温度が、予め定められた上限温度ＴＵを超えている（正常）か、該上限温度ＴＵ以下であって下限温度ＴＬを超えている、あるいは下限温度ＴＬ以下（異常）にあるかを判定する。そして異常の場合にはステップＳ７に進み、正常の場合には前記ステップＳ６の判定を繰り返す。ステップＳ７では、上限温度ＴＵ以下であって下限温度ＴＬを超える場合には第１の監視情報「注意」が作成され、下限温度ＴＬ以下の場合には第２の監視情報「警告」が作成されて、それぞれＲＡＭに格納されて、ステップＳ２５に進む。
【０１０１】
以下のステップＳ２５以下の処理は、当該洗浄監視処理以外の、受け入れ監視処理、保冷処理、環境監視処理にも共通に使用される。ステップＳ２５において、前記監視情報を携帯電話機１１に送信するにあたり、送信回数をゼロにして、ステップＳ２６で待機タイマーをセットする。該待機タイマーは、前記第１の監視情報又は第２の監視情報を携帯電話機１１に送信後、所定の時間経過しても前記第１の監視情報又は第２の監視情報が消去されない時に、再度、前記第１の監視情報又は第２の監視情報を携帯電話機１１に送信するためのタイマーであって、例えば５分間の待機時間を設定する。該再送信は、作動監視制御手段６内の再送信プログラム（再送信手段）で以下のようになされる。
【０１０２】
即ち、ステップＳ２６からステップＳ２７に進み、該ステップＳ２７において、前記作成された第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報を携帯電話機１１に周知の電子メールで送信し、前記待機タイマーをスタートする。ステップＳ２８では前記待機タイマーがタイムアップしたかを監視し、所定の待機時間が経過した場合ステップＳ２９に進む。ステップＳ２９では、第１の監視情報又は第２の監視情報を送信後の携帯電話機１１からの応答を監視する。そして携帯電話機１１から応答があった場合には前記第１の監視情報又は第２の監視情報が消去される。ここで、携帯電話機１１からの応答とは、前記ステップＳ２７にて送信された電子メールを酪農家が見たことを作動監視制御手段６に通知するものである。かかる通知は、携帯電話機１１から送信された電子メールを解読するプログラムを作動監視制御手段６に格納し、このプログラムの実行により電子メールで送信された第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報の内容を解読し、酪農家からの通知であると判断するようにしてもよい。あるいは、携帯電話機１１から応答せずに、作動監視制御手段６のキーボードあるいは、ファンクションキーを押下して電子メールを見たことを作動監視制御手段６に入力するようにしてもよい。
【０１０３】
ステップＳ２９において前記第１の監視情報又は第２の監視情報が消去されていない場合には、ステップＳ３０に進み、前記携帯電話機１１に送信した回数を＋１し、ステップＳ２６に戻る。なお、前記ステップＳ３０において、予め定められた送信回数に達した場合、あるいは、送信回数に関係なくステップＳ２７において監視情報を送信するときに、作動監視制御手段６によって図示していないサイレンあるいは、ランプなどで異常であることを報知するようにしてもよい。また、送信回数は、第１の監視情報と第２の監視情報とで同一として管理してもよく、あるいは第１の監視情報と第２の監視情報それぞれ別に管理してもよい。
【０１０４】
ステップＳ２９において前記第１の監視情報又は第２の監視情報が消去されている場合には、ステップＳ３１に進む。ステップＳ３１更にステップＳ２４は、後述する受け入れ監視処理で使用され、当該洗浄監視処理ではスキップされ、ステップＳ５に戻り洗浄の終了を判定する。ステップＳ５において洗浄が終了している場合には洗浄監視処理を終了し、その後、生乳が投入される場合には受け入れ監視処理が行なわれる。
【０１０５】
次に、受け入れ監視処理について説明する。該受け入れ監視処理において、作動監視制御手段６により、ステップＳ８で初回受け入れ処理かが判定され、初回受け入れ処理の場合にはステップＳ１０に進み、次回受け入れ処理の場合にはステップＳ９に進む。ステップＳ１０では、初回受け入れ処理か次回受け入れ処理かによって、それぞれ異なる監視タイマーがセットされる。例えば、初回受け入れ処理の場合には、図７で示した監視時間ｔ２（３０分）、監視時間ｔ３（３０分）、監視時間ｔ４（６０分）、がＲＯＭから読み出され、それぞれ別々のタイマーに設定される。なお、監視時間ｔ１は、酪農家の規模により異なり、監視タイマーを設けて予め酪農家の規模に応じて監視時間ｔ１を設定するようにしてもよく、あるいは、搾乳終了時にキーボード８等から搾乳終了コマンドを入力するようにしてもよい。また、次回受け入れ処理の場合には、図７で示した監視時間ｔ２（６０分）、監視時間ｔ３（６０分）がＲＯＭから読み出され、それぞれ別々のタイマーに設定される。初回受け入れ処理同様に、監視時間ｔ１は、酪農家の規模により異なり、監視タイマーを設けて予め酪農家の規模に応じて監視時間ｔ１を設定するようにしてもよく、あるいは、搾乳終了時にキーボード８等から搾乳終了コマンドを入力するようにしてもよい。
【０１０６】
そして、ステップＳ１１で前記監視時間ｔ１の監視タイマーがスタートされ、ステップＳ１２に進み、バルククーラー２内の生乳の温度が監視される。ステップＳ１２では、所定時間が終了するまでの間、生乳の温度を判定し、異常の場合にはステップＳ１３に進み、正常の場合にはステップＳ１２に戻り、引き続いて生乳の温度が作動監視制御手段６内の比較処理プログラム（比較手段）で判定される。
【０１０７】
即ち、前記ステップＳ１０で設定されたタイマーが作動している間の前記監視時間ｔ１内において、予め定められた上限温度ＴＵ未満であって該上限温度ＴＵより低い第１の温度ＴＦ以上、あるいは下限温度ＴＬを超え、かつ該下限温度ＴＬより高いか等しい第２の温度ＴＳ以下（以下第１基準と称する）であるかが判定され、この第１基準になった時にステップＳ１３に進む。また、予め定められた上限温度ＴＵ以上あるいは下限温度ＴＬ以下（以下第２基準と称する）であるかが判定され、この第２基準になった時にもステップＳ１３に進む。なお、ステップＳ１２で生乳の温度を監視している間にステップＳ１０で設定されたタイマーがタイムアップした場合には、ステップＳ１０に戻り、それぞれの監視時間内において予め定められた監視温度（ＴＵ、ＴＬ、ＴＦ、ＴＳ）に応じてバルククーラー２内の生乳の温度が監視される。
【０１０８】
ステップＳ１３では、前記第１基準の時に第１の監視情報が、第２基準の時に第２の監視情報が作成され、作動監視制御手段６のＲＡＭに格納されるとともに、ステップＳ２５に進む。ステップＳ２５以降は、ステップＳ３１を除いて前記洗浄監視処理で説明したのと同様な処理がなされる。即ち、監視時間ｔ１においては、生乳の搾乳開始から、終了までの時間ｔ１の間に、前記第１基準または、第２基準になったかが判定される。ステップＳ１３で監視情報が作成されると、前記洗浄監視処理で述べたステップＳ２５以降の処理がなされ、ステップＳ２７では、前記ステップＳ１３で作成された監視情報が作動監視制御手段６から直ちに出力される。当該受け入れ監視処理では、ステップＳ３１の処理が以下のようにしてなされる。即ち、ステップＳ３１では、前記ステップＳ１０でセットされ、ステップＳ１１でスタートされた監視タイマーの終了判定がなされ、該タイマーが終了している場合にはステップＳ２４に進み、それ以外にはステップＳ１２に戻りバルククーラー２内の生乳の温度が監視され、データの判定が続けられる。
【０１０９】
ステップＳ２４では、監視タイマーをクリアして受け入れ監視処理に戻る。そして、ステップＳ８に進み、前記同様にして、初回受け入れ処理の場合にはステップＳ１０に進む。前記監視時間ｔ１の監視タイマーに続いて監視時間ｔ２の監視タイマーが選択され、設定される。その後、生乳の搾乳が終了してから、時間ｔ２までの間、前記第１基準または、第２基準になったかが判定される。以下、時間ｔ２が経過してから時間ｔ３まで、時間ｔ３が経過してから時間ｔ４まで、前記同様にステップＳ１１以降の処理が繰り返されて全ての監視タイマーが使用されて初回受け入れ処理が終了する。初回受け入れ処理が終了した場合には、後述する保冷監視処理に進む。また、次回受け入れ処理が開始されると、次回受け入れ処理用の監視タイマーが前記と同様にしてステップＳ９で順次選択され、設定され、初回受け入れ処理と同様な処理がなされる。
【０１１０】
次に、保冷監視処理について説明する。該保冷監視処理は、前記受け入れ監視処理が終了すると開始される。該保冷監視処理においては、ステップＳ１８で当該処理の終了が判定される。該終了判定は、次回受け入れ処理が開始された時、あるいは、集乳が開始された時に保冷監視処理が終了したと判定される。かかる次回受け入れ処理が開始された時、あるいは、集乳が開始された時の信号は、バルククーラー制御手段１から送信されたバルククーラー２の状態信号を検知してもよく、あるいは、バルククーラー制御手段１の制御状態に応じて操作者がキーボード８からコマンドを入力し、あるいはファンクションキーを押下して前記終了判定をするようにしてもよい。保冷監視処理が終了した場合には当該処理を終了し、それ以外はステップＳ１９に進み、生乳の温度を判定し、異常の場合にはステップＳ２０に進み、正常の場合にはステップＳ１９に戻り、引き続いて生乳の温度が作動監視制御手段６内の比較処理プログラム（比較手段）で判定される。
【０１１１】
即ち、前記ステップＳ１９で、予め定められた上限温度ＴＵ未満であって該上限温度ＴＵより低い第１の温度ＴＦ以上、あるいは下限温度ＴＬを超え、かつ該下限温度ＴＬより高いか等しい第２の温度ＴＳ以下（以下第１基準と称する）であるかが判定され、この第１基準になった時にステップＳ２０に進む。また、予め定められた上限温度ＴＵ以上、あるいは下限温度ＴＬ以下（以下第２基準と称する）であるかが判定され、この第２基準になった時にもステップＳ２０に進む。
【０１１２】
ステップＳ２０では、前記第１基準の時に第１の監視情報が、第２基準の時に第２の監視情報が作成され、作動監視制御手段６のＲＡＭに格納されるとともに、ステップＳ２５に進み、前記洗浄監視処理で述べたステップＳ２５以降の処理がなされ、ステップＳ２７では、前記ステップＳ２０で作成された監視情報が作動監視制御手段６から直ちに出力される。当該保冷監視処理では、ステップＳ３１、ステップＳ２４の処理は、スキップされる。
【０１１３】
以下、第２の実施形態におけるバルククーラー２の洗浄工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６によりバルククーラー２の洗浄工程において、その作動が以下のようにして監視される。該洗浄監視工程では、洗浄開始から終了までの間、洗浄液と排液の温度データを温度測定手段４により得る。前記温度データは、作動監視制御手段６のデータ格納手段の一つであるＲＡＭに格納される。データ格納手段の一つであるＲＯＭに予め格納されている図７に示した監視温度と前記バルククーラー２内の洗浄液及び排液の前記温度データとが、作動監視制御手段６の比較処理プログラム（比較手段）で比較される。前記洗浄液と排液の温度が、それぞれ定められた上限温度ＴＵ（例えば洗浄液は７０℃、排液は４０℃）以下であって下限温度ＴＬ（例えば洗浄液は６５℃、排液は３５℃）を超えている場合には第１の監視情報を、前記下限温度ＴＬ以下となっている場合には前記第１の監視情報より緊急度の高い第２の監視情報が作成され、第１の監視情報又は第２の監視情報と共に、送信時の時刻、送信回数、監視処理の種別が含まれている情報が携帯電話機１１に電子メールで送信されてバルククーラー２の洗浄工程における作動が監視される。
【０１１４】
次に、第２の実施形態におけるバルククーラー２の受け入れ監視工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６により受け入れ監視工程において、その作動は以下のようにして監視される。該受け入れ監視工程では、バルククーラー２に生乳を投入開始後、バルククーラー２内の生乳の温度データが作動監視制御手段６のＲＡＭに格納される。バルククーラー２に生乳を初回投入及び次回以降投入開始後において、前述したようなタイマー監視が開始される。バルククーラー２内の生乳の温度を前記温度測定手段４により得て、データ格納手段の一つであるＲＯＭに予め格納されている図７に示した監視温度と前記バルククーラー２内の生乳の温度データとが、作動監視制御手段６の比較処理プログラム（比較手段）で比較される。
【０１１５】
前記タイマー監視されている時間内において予め定められた上限温度ＴＵ未満であって該上限温度より低い第１の温度ＴＦ以上、あるいは下限温度ＴＬを超え、かつ該下限温度ＴＬより高いか等しい第２の温度ＴＳ以下である場合に第１の監視情報が作成される。また、前記タイマー監視されている時間内において予め定められた上限温度ＴＵ以上または下限温度ＴＬ以下である場合に第１の監視情報より緊急度の高い第２の監視情報が作成される。前記作成された情報は、送信時の時刻、送信回数、監視処理の種別が含まれている情報と共に携帯電話機１１に電子メールで送信されてバルククーラー２の受け入れ工程における作動が監視される。
【０１１６】
次に、第２の実施形態におけるバルククーラー２の保冷監視工程における作動を監視する、作動監視方法について以下に説明する。作動監視制御手段６により保冷監視工程において、その作動は以下のようにして監視される。該保冷監視工程では、バルククーラー２に生乳を投入完了後の所定時間（例えば２時間）経過後から次回搾乳開始あるいは集乳までの間、バルククーラー２内の生乳の温度を前記温度測定手段４により得て、データ格納手段の一つであるＲＯＭに予め格納されている図７に示した監視温度と前記バルククーラー２内の生乳の温度データとが、作動監視制御手段６の比較処理プログラム（比較手段）で比較される。
【０１１７】
予め定められた上限温度ＴＵ（例えば７℃）未満であって該上限温度より低い第１の温度（例えば６℃）以上、あるいは下限温度（例えば２℃）を超え、かつ該下限温度より高いか等しい第２の温度（例えば３℃）以下である場合に第１の監視情報が、予め定められた前記上限温度以上、または下限温度以下である場合に第１の監視情報より緊急度の高い第２の監視情報が作成される。前記作成された情報は、送信時の時刻、送信回数、監視処理の種別が含まれている情報と共に携帯電話機１１に電子メールで送信されてバルククーラー２の保冷監視工程における作動が監視される。
【０１１８】
前記第１の実施形態、第２の実施形態において、作動監視制御手段の近くに操作者がいる場合には前記第１の監視情報の送信をせず、前記第２の監視情報のみを送信するようにしてもよい。あるいは、前記第１の監視情報又は第２の監視情報は、何れか一方、あるいは両方を送信するようにしてもよい。かかる場合には操作者が、処理が開始される前に予めキーボード８からコマンドを入力し、あるいは送信する前記第１の監視情報又は第２の監視情報を決定するファンクションキーを押下して決定してもよい。更に、搾乳終了時間は、酪農家の乳牛の数により異なるので、処理が開始される前に予めキーボード８から搾乳終了時間を入力し、あるいは搾乳終了時間を決定するファンクションキーを選択して押下してもよい。また、夏期などの温度が高温の時には監視温度範囲を狭めてもよく、かかる変更を周囲温度の変化により行うようにしてもよい。
【０１１９】
【発明の効果】
本発明の乳温管理装置の作動監視装置によれば、作動監視制御手段には周知のパーソナルコンピュータを使用し携帯電話機等の携帯通信端末に電子メールを送信することにより、既に設置されている乳温管理装置を改造する必要がないか、あるいはその改造を少なくすることができる。また、その通知形態が、周知の電子メールであることから、周知のプログラムを使用でき、作動監視装置のプログラム開発が容易になる。更に、近年の携帯電話機及びパーソナルコンピュータは低価格であり、乳温管理装置の作動監視装置が低価格に実現できる。そして常に携帯されている携帯電話機に乳温管理装置の異常を通知することで事故を未然に防止でき、本装置により生乳が腐敗するなどして酪農家等に多大な損害を被ることが防止される。
【０１２０】
また、本発明の乳温管理装置の作動監視方法によれば、動作態様に応じて監視処理を、乳温管理装置の洗浄時の作動を監視する洗浄監視処理、前記乳温管理装置の生乳受け入れ時の作動を監視する受け入れ監視処理、前記乳温管理装置の生乳受け入れ後の保冷時の作動を監視する保冷監視処理、乳温管理装置が設置されている周囲温度を監視する環境監視処理とに分けた。そして、各監視処理に応じて独立した監視時間と監視温度を設定し、それぞれの処理毎に監視情報を作成する。そして、乳温管理装置の作動が異常になった時には、携帯電話機に直ちに、あるいは所定時間経過時に通報することにより、酪農家が乳温管理装置から離れた場所にいても乳温管理装置の作動状態に対応した異常を知ることができる。その結果、バルククーラーに収納されている生乳が腐敗するなどして酪農家等に多大な損害を被ることが防止される。

The present invention relates to an operation monitoring device for a milk temperature management device and a monitoring method therefor, and in particular, by transmitting a monitoring result to a communication terminal, the abnormality of the milk temperature management device can be quickly known. .
[0002]
[Prior art]
Raw milk extracted from dairy cows is stored in a storage tank called a bulk cooler. The bulk cooler is a combination of a storage tank and a refrigerator, and keeps milked raw milk at a predetermined temperature to prevent bacterial growth and spoilage until the raw milk is collected. The milk collection process using the bulk cooler is performed as shown in FIG. That is, in order to prevent the growth of bacteria, washing PS1 inside the bulk cooler is performed, and then the raw milk received in the bulk cooler by the first milking PS21 is kept cold PS3 and predetermined until the next milking PS22. Kept at temperature. When the next milking PS22 is completed, the raw milk is cooled PS3 in the same manner as described above, and thereafter, milking is performed a plurality of times (2 to 4 times). Thereafter, when the raw milk is collected G and the bulk cooler is emptied, cleaning PS1 inside the bulk cooler is performed in the same manner as described above.

In general, the washing is performed with warm water washing, alkali washing and acid washing, rinsing, and disinfectant circulation after milk collection, and a washing time and a washing temperature are determined at each washing. Moreover, the recommended value of the temperature of the raw milk in the predetermined time based on the well-known HACCP (Hazard Analysis and Critical Control Points) system is shown at the time of milking and cold preservation. In such a conventional bulk cooler, the temperature change of raw milk in the storage tank is collected by a data logger or the like, and the safety of the raw milk is confirmed by referring to the data. Therefore, if the temperature change of the raw milk in the storage tank is abnormal from the above data, it can be known that the quality of the stored raw milk is a problem, but the raw milk must be discarded, The house suffers a huge loss. In order to prevent such damage and prevent bacterial growth, a technique for cleaning and sterilizing the inside of the bulk cooler after raw milk is collected is known (for example, see Patent Document 1).
[0004]
Moreover, the temperature of the cooler may rise due to a failure of the refrigerator or / and a power failure. As a warning device for such a temperature rise of the cooler, a technique related to a “cooling storage temperature warning device” is also known (for example, see Patent Document 2). This alarm device is composed of a sensor for detecting the internal temperature and a control device (microcomputer) for controlling the alarm device (buzzer, lamp) based on the output of the sensor. This control device (microcomputer) is a warehouse. When the internal temperature reaches the first high temperature alarm temperature higher than the set temperature and the state continues until the predetermined alarm exclusion time elapses, the alarm device (buzzer, lamp) is driven and the first high temperature alarm temperature is reached. When the second high temperature alarm temperature higher than the alarm temperature is reached, the alarm device (buzzer, lamp) is driven without waiting for the alarm exclusion time to elapse.

[Problems to be solved by the invention]
However, as a cleaning method for cleaning and sterilizing the inside of the bulk cooler, for example, alkali cleaning is known. However, in the alkali cleaning, the temperature in the cooler does not reach a predetermined temperature at the time of cleaning due to an operation error or a failure of the cleaning machine. In some cases, sufficient sterilization cannot be performed. In addition, milking is generally performed a plurality of times before raw milk is collected. Therefore, at the time of accepting raw milk, the raw milk previously milked is cooled in the bulk cooler, but the freshly milked raw milk has a high temperature, and the freshly milked raw milk is mixed into the cooled raw milk. Then, the temperature of the raw milk in the bulk cooler temporarily rises. Thereafter, it is cooled by a bulk cooler and lowered to a predetermined temperature. The temperature of raw milk in the bulk cooler changes due to the mixing of new raw milk, but in the event of a power failure, if the cooler is broken, or if the cooler is faulty, for example, an operator error such as forgetting to switch on the refrigerator, etc. If the temperature of the raw milk remains elevated, the raw milk may rot. Alternatively, there are cases where the cooler has failed after cleaning, or the temperature inside the bulk cooler does not decrease due to an operation error. Moreover, the raw milk in the bulk cooler may freeze due to overcooling. Thus, in order to maintain the quality of raw milk, the bulk cooler has a wide variety of operation modes such as washing the bulk cooler, receiving raw milk, and keeping it cool. In particular, the temperature of raw milk in the bulk cooler may rise temporarily due to the addition of raw milk, and the quality of raw milk cannot be maintained by simply measuring the temperature rise of raw milk in the bulk cooler. In other words, it is important to notify a dairy farmer promptly only when an abnormal state is observed by monitoring the operating situation, and at the same time, in some cases, contact a milk collector or an inspection organization.
[0007]
As a technique for notifying when the cooling storage is in an abnormal state, the above-described temperature alarm device for the cooling storage disclosed in Patent Document 2 uses a buzzer and a lamp to warn when the temperature inside the storage becomes higher than the set temperature. Can be issued. However, it is difficult for a dairy farmer to be constantly monitoring the operating state of the cooler when cleaning the cooler, when milking fresh milk, or when keeping it cool. This is especially true during farming and at night during sleep. Therefore, it has been desired to develop an operation monitoring device and a monitoring method for the milk temperature management device that can quickly know when the temperature of the raw milk in the bulk cooler rises or becomes supercooled.
[0008]
The present invention solves such a problem, and even if the dairy farmer is not near the milk temperature management device, the operation of the milk temperature management device can be monitored, and the abnormality can be quickly known when the device is abnormal. The object of the present invention is to provide a device operation monitoring device and a monitoring method therefor.

Note that, after the first monitoring information L1 is output, the first monitoring information L1 is output if the condition for outputting the second monitoring information L2 is satisfied even if the first monitoring information L1 is not deleted. The information L1 is deleted and the second monitoring information L2 is output.
[0038]
In order to facilitate understanding of the invention in the first embodiment, a method for obtaining monitoring information in each of the cleaning monitoring process, the acceptance monitoring process, and the cold insulation monitoring process will be described with reference to FIGS. 3 to 5, the horizontal axis represents time, the vertical axis represents the temperature of a liquid such as raw milk in the milk temperature management device, and the first monitoring information and the second monitoring information are represented by L1 and L2, respectively. . Further, Tb represents the temperature of the liquid in the bulk cooler 2 at the start of the cleaning monitoring process, and TS0 represents the temperature of raw milk at the start of the receiving monitoring process and the cold insulation monitoring process.
[0039]
First, the cleaning monitoring process will be described with reference to FIG. Symbols a, b, c indicate examples of cleaning monitoring processing. The time from the start ts of cleaning to the end te is defined as t4. During a time t4 from the cleaning start ts to the cleaning end te, the temperature (maximum value) of the liquid in the milk temperature management device is equal to or lower than the temperature T7 (upper limit temperature TU) and is lower than the temperature T7 (lower limit temperature). When exceeding (TL), the first monitoring information L1 is output from the operation monitoring control means 6 at the end of cleaning. In addition, when the temperature (maximum value) of the liquid in the milk temperature management apparatus is equal to or lower than the temperature T8 between the start of cleaning and the end of cleaning, the second monitoring information L2 is the operation monitoring control means at the end of cleaning. 6 is output.
[0040]
For example, in the cleaning example indicated by symbol a, the temperature (maximum value) of the liquid in the milk temperature management device exceeds the temperature T7 during the time t4 from the cleaning start ts to the cleaning end te. In such a case, neither the first monitoring information L1 nor the second monitoring information L2 is output. That is, the cleaning is completed normally. Further, in the cleaning example indicated by symbol (b), the temperature (maximum value) of the liquid in the milk temperature management device exceeds the temperature T8 during the time t4 from the cleaning start ts to the cleaning end te, but at the temperature T7 or lower. is there. In such a case, the first monitoring information L1 is output at the end of cleaning. That is, monitoring information that is incompletely cleaned and requires “caution” is output. Further, in the cleaning example indicated by the symbol C, the temperature (maximum value) of the liquid in the milk temperature management device is equal to or lower than the temperature T8 during the time t4 from the cleaning start ts to the cleaning end te. In such a case, second monitoring information L2 having a higher degree of urgency than the first monitoring information is output at the end of cleaning. That is, monitoring information that is incompletely cleaned and requires a “warning” is output.
[0041]
Next, the acceptance monitoring process will be described with reference to FIG. Symbols a, b, c, and d indicate examples of acceptance monitoring processing. After feeding raw milk into the bulk cooler 2 (starting milking), when the time t1 has elapsed (for example, 2 hours after the start of milking), the temperature of the raw milk is equal to or higher than the temperature T1 (upper limit temperature TU1 shown in FIG. 2) or from the temperature T1 When the temperature is lower than the low temperature T2 (the lower limit temperature TL1 shown in FIG. 2) (outside the first acceptance temperature range TS1), the first monitoring information L1 is described later from the operation monitoring control means 6 when the time t1 has elapsed. Is output as follows. In addition, after the raw milk is put into the bulk cooler 2 (milking is started), when a time t2 longer than the time t1 has elapsed (for example, 3 hours after the milking starts), the temperature of the raw milk is lower than the temperature T1 (see FIG. 2). When the temperature is equal to or higher than the upper limit temperature TU2) or lower than the temperature T4 lower than the temperature T3 (lower limit temperature TL2 shown in FIG. 2) (outside the second acceptance temperature range TS2), the first monitoring information L1 indicates the degree of urgency. The high second monitoring information L2 is output from the operation monitoring control means 6 when the time t2 has elapsed. The lower limit temperature TL1 and the lower limit temperature TL2 may be equal.
[0042]
For example, in the acceptance monitoring process indicated by symbol (a), the raw milk temperature is equal to or higher than the temperature T1 at the elapse of time t1 after the start of charging raw milk into the bulk cooler 2, and is outside the first acceptance temperature range TS1. . In such a case, the first monitoring information L1 is output when the time t1 has elapsed. That is, the temperature of raw milk is a temperature that requires “caution”, and monitoring information L1 that requires “caution” is output. In addition, after the start of charging raw milk into the bulk cooler 2, when the time t2 has elapsed, the temperature of the raw milk is equal to or higher than the temperature T3 and is outside the second receiving temperature range TS2. In such a case, the second monitoring information L2 is output when the time t2 has elapsed. That is, the temperature of raw milk is a temperature that requires a “warning”, and monitoring information L2 that requires a “warning” is output.
[0043]
In the acceptance monitoring process indicated by symbol (b), the temperature of the raw milk is less than the temperature T1 and exceeds the temperature T2 when the time t1 elapses after the start of charging raw milk into the bulk cooler 2, and the first acceptance temperature range. Within TS1. In such a case, monitoring information is not output when time t1 has elapsed. However, after the start of charging raw milk into the bulk cooler 2, when the time t2 has elapsed, the temperature of the raw milk is equal to or higher than the temperature T3 and is outside the second acceptance temperature range TS2. In such a case, the second monitoring information L2 is output when the time t2 has elapsed. That is, the temperature of raw milk is a temperature that requires a “warning”, and monitoring information L2 that requires a “warning” is output.
[0044]
In the acceptance monitoring process indicated by reference symbol C, the raw milk temperature is less than the temperature T1 and exceeds the temperature T2 when the time t1 elapses after the start of charging raw milk into the bulk cooler 2, and the first acceptance temperature range. Within TS1. In such a case, monitoring information is not output when time t1 has elapsed. In addition, even after time t2 has elapsed after starting to feed raw milk into the bulk cooler 2, the temperature of the raw milk is less than the temperature T3 and exceeds the temperature T4, and is within the second receiving temperature range TS2. Even in such a case, the monitoring information is not output when the time t2 has elapsed. That is, the operation of the bulk cooler 2 in the reception monitoring process indicated by the symbol C is normal.
[0045]
In the acceptance monitoring process indicated by symbol D, the raw milk temperature is equal to or lower than the temperature T2 when the time t1 elapses after the raw milk is put into the bulk cooler 2, and is outside the first acceptance temperature range TS1. In such a case, the first monitoring information L1 is output when the time t1 has elapsed. That is, the temperature of raw milk is a temperature that requires “caution”, and monitoring information L1 that requires “caution” is output. In addition, after the start of charging raw milk into the bulk cooler 2, when the time t2 has elapsed, the temperature of the raw milk is equal to or lower than the temperature T4 and is outside the second receiving temperature range TS2. In such a case, the second monitoring information L2 is output when the time t2 has elapsed. That is, the temperature of raw milk is a temperature that requires a “warning”, and monitoring information L2 that requires a “warning” is output.
[0046]
Next, the cold insulation monitoring process will be described with reference to FIG. Symbols a, b, c, d, e indicate examples of cold insulation monitoring processing. After the raw milk is charged into the bulk cooler 2, the temperature of the raw milk is not less than the temperature T5 (upper limit temperature TU3 shown in FIG. 2) or lower than the temperature T5 (lower limit temperature TL3 shown in FIG. 2) (cooling temperature range TS3). When the time t3 (for example, 30 minutes) elapses, the monitoring information L2 is output from the operation monitoring control means 6 as described later when the time t3 elapses. The lower limit temperature TL1, the lower limit temperature TL2, and the lower limit temperature TL3 may be equal.
[0047]
For example, in the cold insulation monitoring process indicated by symbol (a), after the raw milk is completely charged into the bulk cooler 2, the temperature of the raw milk becomes equal to or higher than the temperature T5 at time ta1 and is outside the cold insulation temperature range TS3. Even at the time tb1, it is outside the cold insulation temperature range TS3 exceeding the temperature T5. In such a case, the monitoring information L2 is output from the operation monitoring control means 6 when the time t3 has elapsed.
[0048]
In the cold insulation monitoring process indicated by symbol (b), after the raw milk has been charged into the bulk cooler 2, the temperature of the raw milk becomes equal to or higher than the temperature T5 at time ta1 and is outside the cold insulation temperature range TS3, and then at time tb1 after the elapse of time t3. This is a case where the temperature falls below the temperature T5 and falls within the cold insulation temperature range TS3 exceeding the temperature T6. In such a case, the monitoring information L2 is not output from the operation monitoring control means 6.
[0049]
In the cold insulation monitoring process indicated by symbol C, after the raw milk has been charged into the bulk cooler 2, the temperature of the raw milk becomes equal to or lower than the temperature T6 at time ta2 and is outside the cold insulation temperature range TS3, and then at time tb2 after the elapse of time t3. It is in the cold insulation temperature range TS3 that is lower than the temperature T5 and exceeds the temperature T6. In such a case, the monitoring information L2 is not output from the operation monitoring control means 6.
[0050]
In the cold insulation monitoring process indicated by symbol D, after the raw milk has been charged into the bulk cooler 2, the temperature of the raw milk falls below the temperature T6 at time ta2 and is outside the cold insulation temperature range TS3, and then at time tb2 after the elapse of time t3. It is outside the cold insulation temperature range TS3 with the temperature T6 or less. In such a case, the monitoring information L2 is output from the operation monitoring control means 6 when the time t3 has elapsed.
[0051]
In the cold insulation monitoring process indicated by reference sign (E), after the raw milk is completely charged into the bulk cooler 2, the temperature of the raw milk becomes equal to or higher than the temperature T5 at time ta1 and outside the cold insulation temperature range TS3, and then at time tb1 after the elapse of time t3. It becomes temperature T6 or less and is outside the cold insulation temperature range TS3. In such a case, the monitoring information L2 is output from the operation monitoring control means 6.
[0052]
In the cold insulation monitoring process indicated by reference numeral, after the raw milk is charged into the bulk cooler 2, the raw milk temperature falls below the temperature T6 at time ta2 and falls outside the cold insulation temperature range TS3, and then at time tb2 after time t3 has elapsed. It becomes temperature T5 or more and is outside the cold insulation temperature range TS3. In such a case, the monitoring information L2 is output from the operation monitoring control means 6.
[0053]
Hereinafter, the operation of the operation monitoring control means 6 will be described with reference to FIG. Note that the operations of cleaning, receiving, and keeping the bulk cooler 2 are performed by the bulk cooler control means 1 by a well-known method, and the description thereof is omitted. Prior to each monitoring process, the temperature measuring means 4 converts the temperature in the bulk cooler 2 and the room in which the bulk cooler 2 is installed into a digital signal by the A / D converter 5. Note that at least one of the temperature measuring means 4 in the bulk cooler 2 measures the temperature of raw milk in the acceptance monitoring process and the cold insulation monitoring process. The measured temperature data is stored in RAM which is data storage means inside the operation monitoring control means 6 (step S1). The temperature measuring means 4 may be used as raw milk management data so as to measure the temperature in the room in which the bulk cooler 2 is installed in addition to the temperature in the bulk cooler 2. Further, the measured time may be stored together with the measured temperature data. By obtaining time data, it can be used not only as management information when a failure occurs, but also in a well-known HACCP system.
[0054]
The speed at which the temperature data is stored may be a speed that does not hinder the monitoring process, for example, 1 point / 1 to 5 minutes. In such a case, assuming that the milk that has been milked is collected once every two days, it is sufficient that data for 48 hours can be accumulated, and there is only a need for a data storage capacity of a maximum of 2880 points for one temperature measuring means 4. This capacity is a capacity that can be realized even with a normal low-cost data logger, and an operation monitoring device for a low-cost milk temperature management device can be realized using a personal computer with a small RAM capacity.
[0055]
The state of the bulk cooler 2 from the bulk cooler control means 1 via the signal line 1a to which the bulk cooler control means 1 is connected, that is, any of the washing process of the bulk cooler 2, the receiving process of raw milk, or the cold-retaining process of raw milk However, the operation monitoring control means 6 and the bulk cooler control means 1 are not connected to each other according to the control state of the bulk cooler control means 1. The operation monitoring control program may be started by an operator inputting a command from the keyboard 8 or pressing a function key.
[0056]
When the state signal of the state of the bulk cooler 2 transmitted from the bulk cooler control means 1, that is, the state of any of the cleaning process of the bulk cooler 2, the raw milk receiving process, or the raw milk cooling process, is received. Each processing program of the acceptance monitoring process and the cold insulation monitoring process is executed by the operation monitoring control means 6. The data storage process in step S1 may be started simultaneously with the execution of the cleaning monitoring process, the reception monitoring process, and the cold insulation monitoring process. In addition, the cleaning monitoring process, the reception monitoring process, and the cold insulation monitoring process may be executed independently, or the cleaning monitoring process and a plurality of reception monitoring processes and cold insulation monitoring processes are continuously performed. May be executed.
[0057]
First, the cleaning monitoring process will be described. In addition, the milk temperature management apparatus using the bulk cooler 2 as described above has a normal water washing process, an alkali washing process, an acid washing process, and a sterilization process in the washing process, and a predetermined process is performed in each process. . Usually, water washing, alkali washing, and sterilization are performed every time, and acid washing is performed after alkali washing at a frequency of about once every two to three times. Hereinafter, in the description of the cleaning monitoring process and the monitoring method for monitoring the operation in the cleaning process, the alkali cleaning will be described, but the acid cleaning process is the same as the alkali cleaning except that the liquid to be added is an acidic liquid. Therefore, the explanation of the acid cleaning is omitted. Moreover, about the process in a normal water washing process and a sterilization process, a monitoring process is not made | formed. In the cleaning monitoring process, first, in step S5, the end of cleaning is determined. This determination may be made by waiting until the cleaning is completed by discriminating the state signal, or when the cleaning time is known in advance, the cleaning time t4 is set by the timer in the operation monitoring control means 6. You may monitor.
[0058]
When the cleaning is completed, the process proceeds to step S6, and the temperature of the liquid in the bulk cooler 2 during the cleaning stored in the RAM is determined. The determination processing is performed as follows by the comparison processing program (comparison means) in the operation monitoring control means 6. That is, the operation condition monitoring data stored in the ROM as shown in FIG. 2 (monitoring time column, monitoring temperature column and monitoring information column (t4), (TU, TL)) Is sequentially compared with the temperature data in the bulk cooler 2 at the time of cleaning, or when the temperature in the bulk cooler 2 at the time of cleaning is stored in the RAM, compared with the temperature data already stored, In this case, the RAM capacity can be reduced, and a program that always detects only the maximum temperature is executed at the time of cleaning with a light processing load on the operation monitoring control means 6. However, the processing speed is not reduced, or the comparison processing program may be executed sequentially every time data is stored in the RAM. Upon termination of results obtained, sensing the occurrence of a fault can be quickly.
[0059]
According to the comparison processing program, the temperature data of the liquid in the bulk cooler 2 from the start to the end of the cleaning exceeds a predetermined temperature T7 (upper limit temperature) or is equal to or lower than the temperature T7 and the temperature T8 ( It is determined whether the lower limit temperature is exceeded or the temperature is equal to or lower than T8. In step S7, if the temperature exceeds T7, information indicating that the cleaning is normal is stored in the RAM, and the process returns to the acceptance monitoring process. When the temperature is equal to or lower than the temperature T7 and exceeds the temperature T8, the first monitoring information “Caution” is generated. When the temperature is equal to or lower than the temperature T8, the second monitoring information “warning” is generated. Then, the process proceeds to step S25.
[0060]
In addition, the processes in and after step S25 are commonly used for the reception monitoring process and the cold insulation process other than the cleaning monitoring process. In step S25, when transmitting the monitoring information to the mobile phone 11, the number of transmissions is set to zero, and a standby timer is set in step S26. The standby timer again when the first monitoring information or the second monitoring information is not erased even after a predetermined time has passed after the first monitoring information or the second monitoring information is transmitted to the mobile phone 11. A timer for transmitting the first monitoring information or the second monitoring information to the mobile phone 11, for example, sets a waiting time of 5 minutes. The retransmission is performed by the retransmission program (retransmission means) in the operation monitoring control means 6 as follows.
[0061]
That is, the process proceeds from step S26 to step S27. In step S27, information including the time of transmission, the number of times of transmission, and the type of monitoring process is included together with the generated first monitoring information or second monitoring information. Is transmitted to the mobile phone 11 by a well-known e-mail, and the standby timer is started. In step S28, it is monitored whether the standby timer has expired. If a predetermined standby time has elapsed, the process proceeds to step S29. In step S29, the response from the mobile phone 11 after transmitting the first monitoring information or the second monitoring information is monitored. When there is a response from the mobile phone 11, the first monitoring information or the second monitoring information is deleted. Here, the response from the mobile phone 11 is to notify the operation monitoring control means 6 that the dairy farmer saw the e-mail transmitted in the step 27. For this notification, a program for decoding the e-mail transmitted from the mobile phone 11 is stored in the operation monitoring control means 6, together with the first monitoring information or the second monitoring information transmitted by e-mail by the execution of this program. The contents of the information including the time of transmission, the number of transmissions, and the type of monitoring process may be decoded to determine that the notification is from the dairy farmer. Alternatively, instead of responding from the mobile phone 11, it is possible to input to the operation monitoring control unit 6 that the electronic mail is viewed by pressing the keyboard or function key of the operation monitoring control unit 6.
[0062]
If the first monitoring information or the second monitoring information is not erased in step 29, the process proceeds to step S30. If it is erased, the process returns to the acceptance monitoring process. In step S30, the number of times of transmission to the mobile phone 11 is incremented by 1, and the process returns to step S26. In step S30, when the predetermined number of transmissions is reached, or when monitoring information is transmitted in step 27 irrespective of the number of transmissions, a siren, a buzzer, etc. not shown by the operation monitoring control means 6 You may make it alert | report that it is abnormal by the sound of this, or with a lamp | ramp. Further, the number of transmissions may be managed as the same, or may be managed separately for the first monitoring information and the second monitoring information.
[0063]
Next, the acceptance monitoring process will be described. In the acceptance monitoring process, the operation monitoring control means 6 causes the timers 1 and 2 to have predetermined values such as the monitoring times t1 (2 hours) and t2 (3 hours) shown in FIG. Read out and set to each timer. After starting to feed raw milk into the bulk cooler 2, the timer 1 and the timer 2 are started in step S9. In step S10, the operation monitoring control unit 6 monitors the time-up of the timer 1. When the predetermined monitoring time t1 is reached, the operation monitoring control unit 6 proceeds to step S11, and the temperature of the raw milk in the bulk cooler 2 at that time is determined in the operation monitoring control unit 6. The comparison processing program (comparison means) compares as follows.
[0064]
That is, in step S11, when the first time (monitoring time t1) after starting to feed raw milk has elapsed, the operation monitoring control means 6 changes the temperature TU1 and the temperature TL1 shown in FIG. The raw milk temperature data is read from the RAM. The comparison processing program determines whether the temperature of the raw milk when the monitoring time t1 elapses is within the first acceptance temperature range TS1 that is less than the temperature TU1 and exceeds the temperature TL1 that is lower than the temperature TU1. The When the temperature of raw milk is outside the first acceptance temperature range TS1, the process proceeds to step S12 and first monitoring information is created. When the temperature of raw milk is within the first acceptance temperature range TS1, no monitoring information is created. Information that is normal is stored in the RAM for each result, and the process proceeds to step S13.
[0065]
In step S13, the presence / absence of the monitoring information is determined. If the first monitoring information is created, the first monitoring information, the transmission time, and the type of the monitoring process are known to the mobile phone 11 in step S15. The process proceeds to step S14. If the first monitoring information has not been created, the process proceeds to step S14.
[0066]
The operation monitoring control means 6 monitors the time-up of the timer 2 in step S14. When the predetermined monitoring time t2 is reached, the operation monitoring control means 6 proceeds to step S16, and the temperature of the raw milk in the bulk cooler 2 at that time is The comparison processing program (comparison means) compares as follows. That is, in step S16, when the second time (monitoring time t2) after starting to feed raw milk has elapsed, the operation monitoring control means 6 causes the temperature TU2 and the temperature TL2 shown in FIG. The raw milk temperature data is read from the RAM. It is determined by the comparison processing program whether the temperature of the raw milk when the monitoring time t2 has elapsed is within the second acceptance temperature range TS2 that is less than the temperature TU2 and exceeds the temperature TL2 that is lower than the temperature TU2, or is outside the range. . When the temperature of the raw milk is within the second acceptance temperature range TS2, monitoring information is not created and normal information is stored in the RAM, and the acceptance monitoring process is terminated. When the raw milk temperature is outside the second acceptance temperature range TS2, the process proceeds to step S17, where second monitoring information is created and stored in the RAM. Then, in the same manner as described in the cleaning monitoring process, the processes after step S25 are performed. However, the first monitoring information is not transmitted in step S27.
[0067]
Next, the cold insulation monitoring process will be described. The cold insulation monitoring process is started simultaneously with the completion of the acceptance monitoring process. In the cold insulation monitoring process, the operation monitoring control means 6 reads a predetermined value of the timer 3 in step S18, for example, the monitoring time t3 (30 minutes) shown in FIG. At the same time, the temperature TU3 and the temperature TL3 shown in FIG. 2 are read from the ROM. In step S19, the temperature data of the raw milk after completion of charging the raw milk into the bulk cooler 2 is sequentially read from the RAM, and compared with the comparison processing program (comparison means) in the operation monitoring control means 6 as follows. That is, after the raw milk is completely charged, the comparison processing program determines whether the raw milk temperature is within the third acceptance temperature range TS3 that is lower than the temperature TU3 and exceeds the temperature TL3 that is lower than the temperature TU3. Is done. When the temperature of raw milk is outside the third receiving temperature range TS3, the process proceeds to step S20. When the temperature of raw milk is within the third receiving temperature range TS3, the process returns to step S19 and the temperature of raw milk is monitored.
[0068]
In step S20, the timer 3 is started. In step S21, the operation monitoring control unit 6 monitors the time-up of the timer 3. When the predetermined monitoring time t3 is reached, the operation monitoring control unit 6 proceeds to step S22, and the temperature of the raw milk in the bulk cooler 2 at that time is changed to the operation monitoring control unit 6. In the comparison processing program (comparison means), comparison is made as follows. That is, after the raw milk is completely charged, the temperature of the raw milk when the monitoring time t3 has elapsed is within the third acceptance temperature range TS3 that is less than the temperature TU3 and exceeds the temperature TL3 that is lower than the temperature TU3. Is determined. When the raw milk temperature is outside the third acceptance temperature range TS3, the process proceeds to step S23, and after the second monitoring information is created, the process proceeds to step S25. When the temperature of the raw milk is within the third acceptance temperature range TS3, monitoring information is not created but normal information is created and stored in the RAM. The timer 3 is cleared in step S24, and the process returns to step S18. When the second monitoring information is created and the process proceeds to step S25, the processes after step S25 are performed in the same manner as described in the cleaning monitoring process. Note that the timer 3 may be cleared when the temperature of the raw milk falls within the third acceptance temperature range TS3 before the timer 3 expires. In such a case, processing for monitoring the temperature of raw milk is added after the start of the timer 3.
[0069]
Hereinafter, an operation monitoring method for monitoring the operation in the cleaning process of the bulk cooler 2 in the first embodiment will be described. In the cleaning process of the bulk cooler 2, its operation is monitored by the operation monitoring control means 6 as follows. In the cleaning monitoring step, the temperature data of the liquid in the bulk cooler 2 obtained by the temperature measuring unit 4 is stored in the RAM of the operation monitoring control unit 6 from the start to the end of cleaning. Then, by the operation monitoring control means 6, the monitoring temperature data stored in advance in the ROM at the end of cleaning and the temperature of the liquid in the bulk cooler 2 during cleaning stored in the RAM, obtained by the temperature measuring means 4. The data (or maximum temperature) is compared by the comparison means. When the comparison result is equal to or lower than the temperature TU and exceeds the temperature TL lower than the temperature TU, the first monitoring information is more urgent than the first monitoring information when the temperature is equal to or lower than the temperature TL. High second monitoring information is created. In addition to the first monitoring information or the second monitoring information, information including the time of transmission, the number of times of transmission, and the type of monitoring processing is transmitted to the mobile phone 11 by e-mail, and in the cleaning process of the bulk cooler 2 Operation is monitored.
[0070]
Next, an operation monitoring method for monitoring the operation in the acceptance monitoring process of the bulk cooler 2 in the first embodiment will be described below. In the reception monitoring process, the operation is monitored as follows by the operation monitoring control means 6. In the acceptance monitoring step, the temperature data of the raw milk in the bulk cooler 2 is stored in the RAM of the operation monitoring control means 6 after starting the feeding of the raw milk into the bulk cooler 2. In addition, after starting to put raw milk into the bulk cooler 2, timer monitoring is started, and when the timer passes the first time t1, the temperature of the raw milk in the bulk cooler 2 is measured. The temperature data of raw milk when the timer has passed the first time t1 and the monitored temperature data in the ROM are compared by the comparison means. It is detected whether the comparison result is within the first acceptance temperature range TS1 that is less than the temperature TU1 and exceeds the temperature TL1 that is lower than the temperature TU1. As a result, when the temperature falls outside the first acceptance temperature range, first monitoring information is created and stored in the RAM.
[0071]
When the first monitoring information has been created, information including the number of transmissions, the time of transmission, and the type of monitoring processing is transmitted to the mobile phone 11 together with the first monitoring information. Thereafter, when the timer started after starting the feeding of raw milk into the bulk cooler 2 has passed a second time t2 longer than the first time t1, the temperature of the raw milk in the bulk cooler 2 is measured. The temperature data of the raw milk when the second time t2 has passed and the monitored temperature data in the ROM are compared by the comparison means. It is detected whether the comparison result is within or outside the second acceptance temperature range TS2 that is less than the temperature TU2 and exceeds the temperature TL2 that is lower than the temperature TU2. As a result, when the temperature falls outside the second acceptance temperature range, second monitoring information having a higher degree of urgency than the first monitoring information is created and stored in the RAM. Along with the second monitoring information, the transmission time, the number of transmissions, and the type of the monitoring process are transmitted to the mobile phone 11, and the operation of the bulk cooler 2 in the reception monitoring process is monitored.
[0072]
Next, an operation monitoring method for monitoring the operation of the bulk cooler 2 according to the first embodiment in the cold insulation monitoring step will be described below. In the cold insulation monitoring step, the operation is monitored by the operation monitoring control means 6 as follows. In the cold insulation monitoring step, after the raw milk is completely charged into the bulk cooler 2, the temperature data of the raw milk in the bulk cooler 2 is stored in the RAM, and the monitored temperature data in the ROM and the temperature data of the raw milk in the bulk cooler 2 are stored. Comparison is made by the comparison means. It is detected whether the comparison result is less than the temperature TU3 and within the cold insulation temperature range TS3 exceeding the temperature TL3 lower than the temperature TU3. As a result, timer monitoring is started when the temperature is outside the cold insulation temperature range TS3. When the timer elapses for the third time t3, the temperature of the raw milk in the bulk cooler 2 is measured, and when it is outside the cold insulation temperature range TS3, monitoring information is created and stored in the RAM. Along with the monitoring information, the transmission time, the number of transmissions, and the type of the monitoring process are transmitted to the mobile phone 11, and the operation of the bulk cooler 2 in the cold insulation monitoring process is monitored. When the monitoring information is not created, the timer is cleared, and the process of comparing the monitoring temperature data in the ROM with the raw milk temperature in the bulk cooler 2 is continued.
[0073]
The room and / or milk temperature, the temperature of the liquid in the bulk cooler 2 at the time of cleaning, the transmission history to the mobile phone 11 and the like are transmitted to the factory and / or the inspection organization 13. It may be used as management information for raw milk. As a result, the operation monitoring device and the monitoring method of the milk temperature management device of the present invention can be applied to a well-known HACCP system.
[0074]
Next, a second embodiment implemented by the configuration of the embodiment will be described. In the second embodiment, the first monitoring information or the second monitoring information is issued at any time during the cleaning monitoring process, the reception monitoring process, the cold insulation monitoring process, and the environment monitoring process. That is, in the cleaning monitoring process, the liquid temperature (the temperature of the cleaning liquid and the drained liquid) is monitored from the start of cleaning to the end of cleaning, and immediately when an abnormality occurs that causes the liquid temperature to be outside the predetermined temperature range. The first monitoring information or the second monitoring information is transmitted to the communication terminal. Also, in the acceptance monitoring process, different monitoring processes are performed for the first acceptance and the acceptance after the next, and when the raw milk temperature is out of the predetermined temperature range after the start of feeding raw milk, the first monitoring information is immediately obtained. Alternatively, the second monitoring information is transmitted to the communication terminal. Further, in the cold monitoring process and the environmental monitoring process for monitoring the room temperature where the bulk cooler is installed, when the temperature of raw milk and the room temperature are outside the predetermined temperature range, the first monitoring information or the first 2 monitoring information is transmitted to the communication terminal at any time. In any case, it is desirable that the operation monitoring control means 6 stores data obtained from the temperature measurement means 4 in a RAM which is one of the data storage means.
[0075]
A data structure used by the operation monitoring control means 6 in the second embodiment will be described with reference to FIG. Operation monitoring data consisting of (t1 to t4), (TU, TL, TF, TS, TO) and monitoring information stored in the ROM of the operation monitoring control means 6 in the monitoring time column, the monitoring temperature column and the monitoring information column. The (first information, second information) is used in the cleaning monitoring process, the acceptance monitoring process, the cold insulation monitoring process, and the environment monitoring process shown in the processing column. TO in the monitoring information column is the temperature to be measured. In addition, the monitoring time (t1 to t4), the monitoring temperature (TU, TL, TF, TS), the value added in parentheses to the monitoring information, or the way of expressing the monitoring information is an example, Other values or representations may be used. The monitoring information includes first monitoring information and second monitoring information, and the second monitoring information is information with a higher degree of urgency than the first monitoring information. That is, it indicates that a failure that may cause serious damage to the dairy farmer has occurred, and when the e-mail is transmitted to the communication terminal 11 (hereinafter referred to as a mobile phone), the first monitoring information and the first The second monitoring information is expressed by specific information such as “caution” and “warning”. In the next acceptance process, when the number of milking is large, a fourth time t4 may be provided after the third time t3. In such a case, for example, the same time as the third time t3. May be set, or other time may be set. Further, after the first monitoring information L1 shown in FIGS. 8 to 10 is output, even if the first monitoring information L1 is not deleted, the condition for outputting the second monitoring information L2 is satisfied. Deletes the first monitoring information L1 and outputs the second monitoring information L2.
[0076]
In order to facilitate understanding of the invention in the second embodiment, a method for obtaining monitoring information in each of the cleaning monitoring process, the acceptance monitoring process, the cold insulation monitoring process, and the environmental monitoring process will be described below with reference to FIGS. Explained. 8 to 10, the horizontal axis represents time, the vertical axis represents the temperature of raw milk or liquid in the milk temperature management device, and the first monitoring information and the second monitoring information are represented by L1 and L2, respectively. Further, Tb represents the temperature of the liquid in the bulk cooler 2 at the start of the cleaning monitoring process, and TS0 represents the temperature of raw milk at the start of the receiving monitoring process and the cold insulation monitoring process.
[0077]
First, the cleaning monitoring process will be described with reference to FIG. Symbols a, b, c, and d show examples of the cleaning monitoring process PS1 (see FIG. 12). When the liquid temperature in the bulk cooler 2 is not more than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU between the cleaning start ts and the cleaning end te, the first monitoring information L1 is immediately Output from the operation monitoring control means 6. Further, when the liquid temperature is equal to or lower than the lower limit temperature TL between the cleaning start ts and the cleaning end te, the second monitoring information L2 is immediately output from the operation monitoring control means 6. Here, as for the liquid temperature, the cleaning liquid and the drainage liquid are monitored independently, and the upper limit temperature and the lower limit temperature are determined for the cleaning liquid and the drainage liquid, respectively. The first monitoring information and the second monitoring information that are independent from each other are output based on the temperature and the lower limit temperature. In FIG. 8, the cleaning liquid monitoring process will be described. The drain liquid monitoring process is the same except that the monitoring temperature is different, and the description thereof will be omitted. The cleaning liquid and drainage liquid may have a low temperature at the start of cleaning. In such a case, as shown in FIG. 8, it may be programmed to delay the start of the cleaning monitoring process by a predetermined time th from the cleaning start ts.
[0078]
In FIG. 8, in the cleaning example indicated by symbol a, the temperature of the cleaning liquid is equal to or lower than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU from the start of cleaning ts to the time indicated by the point P0. Until the predetermined time th, the cleaning monitoring process is not performed as described above, and monitoring information is not output. The condition is satisfied from the predetermined time th to the time indicated by the point P0, and the first monitoring information L1 is immediately output at the predetermined time th. That is, monitoring information that is incompletely cleaned and requires “caution” is output. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. Since the upper limit temperature TU is exceeded from the time indicated by the point P0 until the cleaning end te, neither the first monitoring information L1 nor the second monitoring information L2 is output.
[0079]
In the cleaning example indicated by symbol B, the temperature of the cleaning liquid is not more than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU from the start of cleaning ts to the end of cleaning te. In such a case, the first monitoring information L1 is immediately output at a certain time th. That is, monitoring information that is incompletely cleaned and requires “caution” is output. Once the monitoring information is output, the same monitoring information is not output until a predetermined time elapses as described above. If the monitoring information transmitted before the predetermined time has not been deleted, the same monitoring information is transmitted again.
[0080]
In the cleaning example indicated by the symbol C, the temperature of the cleaning liquid is not more than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU from the start of cleaning ts to the time indicated by the point P2. Until the predetermined time th, the cleaning monitoring process is not performed as described above, and monitoring information is not output. The condition is satisfied from the predetermined time th to the time indicated by the point P2, and the first monitoring information L1 is immediately output at the predetermined time th. That is, monitoring information that is incompletely cleaned and requires “caution” is output. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. Further, the temperature of the cleaning liquid is equal to or lower than the lower limit temperature TL from the time indicated by the point P2 to the time indicated by the point P3. In such a case, the second monitoring information L2 is immediately output at the time indicated by the point P2. That is, monitoring information that is incompletely cleaned and requires a “warning” is output. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. Furthermore, from the time indicated by point P3 to the end of cleaning te, the temperature of the cleaning liquid is not more than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU. In such a case, the first monitoring information L1 is immediately output at the time indicated by the point P3.
[0081]
In the cleaning example indicated by symbol D, the temperature of the cleaning liquid is not more than the upper limit temperature TU and exceeds the lower limit temperature TL lower than the upper limit temperature TU from the start of cleaning ts to the time indicated by the point P1. Until the predetermined time th, the cleaning monitoring process is not performed as described above, and monitoring information is not output. The time indicated by the point P1 is before a certain time th, and since the upper limit temperature TU is exceeded from the certain time th to the cleaning end te, neither the first monitoring information L1 nor the second monitoring information L2 is output. .
[0082]
Next, the acceptance monitoring process will be described with reference to FIG. A symbol a indicates an example of the acceptance monitoring process PS2 (see FIG. 12). The acceptance monitoring process at the first milking PS21 and the acceptance monitoring process at the next milking PS22 differ only in the monitoring time, the monitoring temperature, and the number of times of monitoring as shown in FIG. The acceptance monitoring process of milking PS21 is demonstrated as code | symbol PS2, and the description is abbreviate | omitted about the acceptance monitoring process about next milking PS22.
[0083]
The temperature of the raw milk is less than the upper limit temperature TU1 until the first time elapses (starting from milking start time ts) to the time t1 when milking ends until the first time elapses (depending on the number of cows). When the temperature is equal to or higher than the first temperature TF1 lower than the upper limit temperature TU1 or higher than the lower limit temperature TL1 and lower than the second temperature TS1 higher than the lower limit temperature TL1, the first monitoring information L1 is immediately monitored and controlled. 6 is output. Further, when the temperature of raw milk is not less than the upper limit temperature TU1 or not more than the lower limit temperature TL1, the second monitoring information L2 having a higher degree of urgency than the first monitoring information L1 is immediately output from the operation monitoring control means 6. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. The lower limit temperature TL1 and the second temperature TS1 may be equal. At the end of milking, the end of milking may be input from the keyboard 8 or the like, or may be set in advance according to the scale of the dairy farmer.
[0084]
Similarly, the first temperature TF2 where the temperature of the raw milk is lower than the upper limit temperature TU2 and lower than the upper limit temperature TU2 until the second time (for example, 30 minutes) from the milking end time t1 to the time t2 elapses. The first monitoring information L1 is immediately output from the operation monitoring control means 6 when it is above or below the second temperature TS2 that exceeds the lower limit temperature TL2 and is higher than the lower limit temperature TL2. Further, when the temperature of raw milk is not less than the upper limit temperature TU2 or not more than the lower limit temperature TL2, the second monitoring information L2 having a higher degree of urgency than the first monitoring information L1 is immediately output from the operation monitoring control means 6. The lower limit temperature TL2 and the second temperature TS2 may be equal. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed.
[0085]
Similarly, the temperature of raw milk is lower than the upper limit temperature TU3 and lower than the upper limit temperature TU3 by a third time (for example, 30 minutes) from time t2 to time t3, Alternatively, the first monitoring information L1 is immediately output from the operation monitoring control means 6 when the temperature exceeds the lower limit temperature TL3 and is equal to or lower than the second temperature TS3 higher than the lower limit temperature TL3. In addition, when the temperature of raw milk is equal to or higher than the upper limit temperature TU3 or lower than the lower limit temperature TL3, the second monitoring information L2 having a higher degree of urgency than the first monitoring information L1 is immediately output from the operation monitoring control means 6. The lower limit temperature TL3 and the second temperature TS3 may be equal. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed.
[0086]
Similarly, the temperature of the raw milk is lower than the upper limit temperature TU4 and lower than the upper limit temperature TU4 by a fourth time (for example, 60 minutes) from time t3 to time t4, Alternatively, when the temperature exceeds the lower limit temperature TL4 and is equal to or lower than the second temperature TS4 higher than the lower limit temperature TL4, the first monitoring information L1 is immediately output from the operation monitoring control means 6. Further, when the temperature of raw milk is equal to or higher than the upper limit temperature TU4 or lower than the lower limit temperature TL4, the second monitoring information L2 having a higher degree of urgency than the first monitoring information L1 is immediately output from the operation monitoring control means 6. The lower limit temperature TL4 and the second temperature TS4 may be equal. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. After time t4, the cold insulation process PS3 (see FIG. 12) is started.
[0087]
For example, in the acceptance monitoring process indicated by the symbol a, the following process is performed until the fourth time from the milking start time ts to the time t4 elapses. That is, with reference to the upper limit temperature TU1, the lower limit temperature TL1, the first temperature TF1, and the second temperature TS1 that are set in advance within the first time, the raw milk temperature is compared with the temperature. . In FIG. 9, the temperature of raw milk is equal to or higher than the upper limit temperature TU1 from the milking start time ts to the time indicated by the point P0. In such a case, the second monitoring information L2 is immediately output at the milking start time ts. In many cases, the milking start time ts is monitored by the dairy farmer beside the bulk cooler 2, and in such a case, the second monitoring information L2 immediately after the start of milking may not be output. . Such a process may be programmed to delay the start of the acceptance monitoring process, similar to the cleaning process.
[0088]
From the time indicated by the point P0 to the time indicated by the point P1, the temperature of the raw milk is lower than the upper limit temperature TU1 but higher than the first temperature TF1. In such a case, the first monitoring information L1 is immediately output at the time indicated by the point P0. Furthermore, from the time indicated by the point P1 to the time indicated by the point P2, the temperature of the raw milk is lower than the first temperature TF1 and higher than the second temperature TS1. In such a case, monitoring information is not output. However, from the time indicated by the point P2 to the time indicated by the point P3, the temperature of the raw milk is equal to or lower than the second temperature TS1, but exceeds the lower limit temperature TL1. In such a case, the first monitoring information L1 is immediately output at the time indicated by the point P2. And from the time shown by point P3 to time t1, the temperature of raw milk is below lower limit temperature TL1. In such a case, the second monitoring information L2 is immediately output at the time indicated by the point P3. In any case, once the monitoring information is output, the same monitoring information is not output until a predetermined time (for example, 5 minutes) elapses. In the same manner, the upper limit temperature TUn, the lower limit temperature TLn, the first temperature TFn, and the second temperature determined within each time until the second time, the third time, and the fourth time elapse. With reference to TSn, it is compared where the temperature of raw milk is at said temperature. However, n = 2, 3, and 4.
[0089]
Next, the cold insulation monitoring process PS3 (see FIG. 12) will be described with reference to FIG. Symbols a, b, and c show examples of the cold insulation monitoring process. The first milk temperature is lower than the upper limit temperature TU and lower than the upper limit temperature TU from the time ts after the first or next receiving process to the time te when the next receiving process or milk collection is started. When the temperature is equal to or higher than the temperature TF, or exceeds the lower limit temperature TL and equal to or lower than the second temperature TS higher than the lower limit temperature TL, the first monitoring information L1 is immediately output from the operation monitoring control means 6. In addition, when the temperature of the raw milk is equal to or higher than the upper limit temperature TU or lower than the lower limit temperature TL, the second monitoring information L2 having a higher degree of urgency than the first monitoring information L1 is immediately output from the operation monitoring control means 6. Once the monitoring information is output, the same monitoring information is not output until a predetermined time has elapsed. The lower limit temperature TL and the second temperature TS may be equal.
[0090]
For example, in the cold insulation monitoring process indicated by symbol (i), the temperature of raw milk is less than the upper limit temperature TU at the time indicated by the point P0 after the time ts after the first or next acceptance process, and from the upper limit temperature TU. The temperature becomes equal to or higher than the low first temperature TF, and then becomes equal to or higher than the upper limit temperature TU at the time indicated by the point P1, and the next receiving process or milk collection is started at time te. In such a case, the first monitoring information acquisition L1 is immediately output from the operation monitoring control means 6 at the time indicated by the point P0. Further, the second monitoring information acquisition L2 is immediately output from the operation monitoring control means 6 at the time indicated by the point P1. In any case, once the monitoring information is output, the same monitoring information is not output until a predetermined time (for example, 5 minutes) elapses.
[0091]
In the cold insulation monitoring process indicated by symbol B, the temperature of raw milk is less than the first temperature TF until the next receiving process or milk collection is started after the time ts after the first or next receiving process. Since the second temperature TS is exceeded, the monitoring information is not output from the operation monitoring control means 6.
[0092]
In the cold insulation monitoring process indicated by the symbol C, after the time ts after the first or next acceptance process, the temperature of the raw milk is equal to or lower than the second temperature TS at the time indicated by the point P2 and exceeds the lower limit temperature TL. After that, at the time indicated by the point P3, the temperature becomes lower than the lower limit temperature TL, and the next receiving process or milk collection is started at the time te. In such a case, the first monitoring information L1 is immediately output from the operation monitoring control means 6 at the time indicated by the point P2. Further, the second monitoring information L2 is immediately output from the operation monitoring control means 6 at the time indicated by the point P3. In any case, once the monitoring information is output, the same monitoring information is not output until a predetermined time (for example, 5 minutes) elapses.
[0093]
The environmental monitoring process is not always monitored from the first or next receiving process until the time te when the next receiving process or the collection of milk is started, as in the case of the cold insulation process. Is. The cooling process is the same as the determination process except that the monitoring time and the monitoring temperature are different as shown in FIG. 7, and the description thereof is omitted.
[0094]
Hereinafter, the operation of the operation monitoring control means 6 will be described with reference to FIG. Note that the operations of cleaning, receiving, and keeping the bulk cooler 2 are performed by the bulk cooler control means 1 by a well-known method, and the description thereof is omitted. Prior to each of the monitoring processes, the temperature measuring means 4 converts the temperature of the cleaning liquid, waste liquid, raw milk in the bulk cooler 2 and the temperature in the room where the bulk cooler 2 is installed into a digital signal by the A / D converter 5. It has been converted. The temperature measuring means 4 measures the temperature of the cleaning liquid and the waste liquid in the cleaning process, measures the temperature of raw milk in the acceptance monitoring process and the cold insulation monitoring process, and the bulk cooler 2 is installed in the environmental monitoring process. Measure the room temperature.
[0095]
The measured temperature data is stored in a RAM which is data storage means inside the operation monitoring control means 6 (step S1). The measured time may be stored together with the measured temperature data. By obtaining time data, it can be used not only as management information when a failure occurs, but also in a well-known HACCP system. The speed at which the temperature data is stored may be a speed that does not hinder the monitoring process, for example, 1 point / 1 to 5 minutes. In such a case, assuming that the collected raw milk is collected once every two days, it is sufficient that data for 48 hours can be accumulated, and there is only a need for a data storage capacity of a maximum of 2880 points for one temperature measuring means 4. This capacity is a capacity that can be realized even with a normal low-cost data logger, and an operation monitoring device for a low-cost milk temperature management device can be realized using a personal computer with a small RAM capacity.
[0096]
The state of the bulk cooler 2 from the bulk cooler control means 1 via the signal line 1a to which the bulk cooler control means 1 is connected, that is, any of the washing process of the bulk cooler 2, the receiving process of raw milk, or the cold-retaining process of raw milk However, the operation monitoring control means 6 and the bulk cooler control means 1 are not connected to each other according to the control state of the bulk cooler control means 1. The operation monitoring control program may be started by an operator inputting a command from the keyboard 8 or pressing a function key.
[0097]
When the state signal of the state of the bulk cooler 2 transmitted from the bulk cooler control means 1, that is, the state of any of the cleaning process of the bulk cooler 2, the raw milk receiving process, or the raw milk cooling process, is received. Each processing program of the acceptance monitoring process, the cold insulation monitoring process, and the environment monitoring process is executed by the operation monitoring control means 6. The data storage process in step S1 may be started simultaneously with the execution of the cleaning monitoring process, the reception monitoring process, and the cold insulation monitoring process. In addition, the cleaning monitoring process, the reception monitoring process, and the cold insulation monitoring process may be executed independently, or the cleaning monitoring process and a plurality of reception monitoring processes and cold insulation monitoring processes are continuously performed. May be executed. Furthermore, it is desirable that the environment monitoring process is a multitask process performed in parallel with each of the above processes, and the cleaning is started in accordance with the state of the bulk cooler 2 transmitted from the bulk cooler control means 1. You may make it operate | move constantly, independently of each processing program of a monitoring process, an acceptance monitoring process, and a cold storage monitoring process.
[0098]
First, the cleaning monitoring process will be described. In addition, the milk temperature management apparatus using the bulk cooler 2 as described above usually has a warming water washing (water washing process), an alkali washing (alkaline washing process), and an acid washing (acid washing process) after milk collection in the washing process. Rinse, bactericidal agent circulation (sterilization step) is performed, and in each of the steps, predetermined processing is performed. Usually, water washing and alkali washing are usually carried out every time, and acid washing is often carried out after alkali washing at a frequency of once every 2 to 3 alkali washings. In the following description of the cleaning monitoring process and the operation monitoring method for monitoring the operation in the cleaning process, the alkali cleaning will be described, but the acid cleaning process is the same as the alkali cleaning except that the liquid to be added is an acidic liquid. Therefore, the explanation of the acid cleaning is omitted. Moreover, about the process in a normal water washing process and a sterilization process, a monitoring process is not made | formed. In the cleaning monitoring process, first, in step S5, the end of cleaning is determined. This determination may be made by waiting until the cleaning is completed by determining the state signal, or when the cleaning time is known in advance, the cleaning time t4 is monitored by the timer in the operation monitoring control means 6. May be.
[0099]
If the cleaning has not been completed, the process proceeds to step S6, where the temperature of the cleaning liquid and the drainage in the milk temperature management device is measured, and the temperatures are determined based on the determined upper limit temperature and lower limit temperature, respectively. The first monitoring information and the second monitoring information are output as will be described later. The data discrimination processing is performed as follows by the comparison processing program (comparison means) in the operation monitoring control means 6. That is, the operation monitoring data stored in the ROM as shown in FIG. 7 (monitoring time column, monitoring temperature column and monitoring information column (t4), (TU, TL)), and the milk The temperature data of the cleaning liquid in the temperature management device and the drainage liquid are sequentially compared. As a result of the sequential comparison of the temperature data, the temperature data need not be stored in the RAM. In such a case, the RAM capacity can be reduced. The temperature data may be stored in the RAM as management data for the later date. Further, by sequentially comparing the temperature data, the temperature of the cleaning liquid and the drainage liquid can be obtained immediately, and the occurrence of a failure during cleaning can be quickly detected.
[0100]
According to the comparison processing program, the temperature of the cleaning liquid and the drainage liquid is higher than a predetermined upper limit temperature TU (normal) or lower than the upper limit temperature TU and lower limit temperature TL from the start to the end of cleaning. Or whether it is below the lower limit temperature TL (abnormal). If abnormal, the process proceeds to step S7, and if normal, the determination in step S6 is repeated. In step S7, when the temperature is lower than the upper limit temperature TU and exceeds the lower limit temperature TL, the first monitoring information "Caution" is created, and when the temperature is lower than the lower limit temperature TL, the second monitoring information "Warning" is created. Are respectively stored in the RAM, and the process proceeds to step S25.
[0101]
The processes after step S25 below are also used in common for the acceptance monitoring process, the cold insulation process, and the environment monitoring process other than the cleaning monitoring process. In step S25, when transmitting the monitoring information to the mobile phone 11, the number of transmissions is set to zero, and a standby timer is set in step S26. The standby timer again when the first monitoring information or the second monitoring information is not erased even after a predetermined time has passed after the first monitoring information or the second monitoring information is transmitted to the mobile phone 11. A timer for transmitting the first monitoring information or the second monitoring information to the mobile phone 11, for example, sets a waiting time of 5 minutes. The retransmission is performed by the retransmission program (retransmission means) in the operation monitoring control means 6 as follows.
[0102]
That is, the process proceeds from step S26 to step S27. In step S27, information including the time of transmission, the number of times of transmission, and the type of monitoring process is included together with the generated first monitoring information or second monitoring information. Is transmitted to the mobile phone 11 by a well-known e-mail, and the standby timer is started. In step S28, it is monitored whether the standby timer has expired. If a predetermined standby time has elapsed, the process proceeds to step S29. In step S29, the response from the mobile phone 11 after transmitting the first monitoring information or the second monitoring information is monitored. When there is a response from the mobile phone 11, the first monitoring information or the second monitoring information is deleted. Here, the response from the mobile phone 11 is to notify the operation monitoring control means 6 that the dairy farmer has seen the electronic mail transmitted in step S27. For this notification, a program for decoding the e-mail transmitted from the mobile phone 11 is stored in the operation monitoring control means 6, together with the first monitoring information or the second monitoring information transmitted by e-mail by the execution of this program. The contents of the information including the time of transmission, the number of transmissions, and the type of monitoring process may be decoded to determine that the notification is from the dairy farmer. Alternatively, instead of responding from the mobile phone 11, it is possible to input to the operation monitoring control unit 6 that the electronic mail is viewed by pressing the keyboard or function key of the operation monitoring control unit 6.
[0103]
If the first monitoring information or the second monitoring information has not been deleted in step S29, the process proceeds to step S30, the number of times transmitted to the mobile phone 11 is incremented by 1, and the process returns to step S26. When the predetermined number of transmissions is reached in step S30, or when monitoring information is transmitted in step S27 regardless of the number of transmissions, a siren or lamp not shown by the operation monitoring control means 6 is shown. You may make it alert | report that it is abnormal. The number of transmissions may be managed as the same for the first monitoring information and the second monitoring information, or may be managed separately for the first monitoring information and the second monitoring information.
[0104]
If the first monitoring information or the second monitoring information has been deleted in step S29, the process proceeds to step S31. Step S31 Further, step S24 is used in an acceptance monitoring process described later, skipped in the cleaning monitoring process, and returns to step S5 to determine the end of cleaning. If the cleaning is completed in step S5, the cleaning monitoring process is ended. After that, when raw milk is introduced, an acceptance monitoring process is performed.
[0105]
Next, the acceptance monitoring process will be described. In the acceptance monitoring process, the operation monitoring control means 6 determines whether or not the initial acceptance process is performed in step S8. In the case of the initial acceptance process, the process proceeds to step S10, and in the case of the next acceptance process, the process proceeds to step S9. In step S10, different monitoring timers are set depending on whether the initial acceptance process or the next acceptance process. For example, in the case of the initial acceptance process, the monitoring time t2 (30 minutes), the monitoring time t3 (30 minutes), and the monitoring time t4 (60 minutes) shown in FIG. Set to Note that the monitoring time t1 varies depending on the size of the dairy farmer, and a monitoring timer may be provided to set the monitoring time t1 in advance according to the scale of the dairy farmer. A command may be input. In the case of the next acceptance process, the monitoring time t2 (60 minutes) and the monitoring time t3 (60 minutes) shown in FIG. 7 are read from the ROM and set to separate timers. Similar to the initial acceptance process, the monitoring time t1 varies depending on the size of the dairy farmer, and a monitoring timer may be provided to set the monitoring time t1 in advance according to the scale of the dairy farmer. For example, a milking end command may be input.
[0106]
Then, in step S11, a monitoring timer for the monitoring time t1 is started, the process proceeds to step S12, and the temperature of raw milk in the bulk cooler 2 is monitored. In step S12, the temperature of the raw milk is determined until the predetermined time ends, and if abnormal, the process proceeds to step S13, and if normal, the process returns to step S12. 6 is determined by the comparison processing program (comparison means).
[0107]
That is, within the monitoring time t1 during the operation of the timer set in step S10, the temperature is not less than a first temperature TF that is lower than the predetermined upper limit temperature TU and lower than the upper limit temperature TU, or the lower limit. It is determined whether the temperature is higher than or equal to the lower temperature TL and is equal to or lower than a second temperature TS (hereinafter referred to as a first reference). When the first reference is reached, the process proceeds to step S13. Further, it is determined whether the temperature is equal to or higher than a predetermined upper limit temperature TU or lower than a lower limit temperature TL (hereinafter referred to as a second reference), and the process proceeds to step S13 when the second reference is reached. If the timer set in step S10 has expired while the temperature of raw milk is being monitored in step S12, the process returns to step S10, and a predetermined monitoring temperature (TU, The temperature of the raw milk in the bulk cooler 2 is monitored according to TL, TF, TS).
[0108]
In step S13, the first monitoring information is created at the time of the first reference, and the second monitoring information is created at the time of the second reference, stored in the RAM of the operation monitoring control means 6, and the process proceeds to step S25. After step S25, processing similar to that described in the cleaning monitoring process is performed except for step S31. That is, at the monitoring time t1, it is determined whether the first reference or the second reference is satisfied during the time t1 from the start of milking to the end. When the monitoring information is created in step S13, the processing after step S25 described in the cleaning monitoring processing is performed. In step S27, the monitoring information created in step S13 is immediately output from the operation monitoring control means 6. . In the acceptance monitoring process, the process of step S31 is performed as follows. That is, in step S31, it is determined whether or not the monitoring timer set in step S10 and started in step S11 is terminated. If the timer has expired, the process proceeds to step S24. Otherwise, the process returns to step S12. The temperature of raw milk in the bulk cooler 2 is monitored, and data determination is continued.
[0109]
In step S24, the monitoring timer is cleared and the process returns to the acceptance monitoring process. Then, the process proceeds to step S8, and similarly to the above, the process proceeds to step S10 in the case of the initial acceptance process. Following the monitoring timer at the monitoring time t1, a monitoring timer at the monitoring time t2 is selected and set. Then, after milking of raw milk is complete | finished, it is determined whether it became the said 1st reference | standard or the 2nd reference | standard until time t2. Thereafter, from time t2 to time t3, from time t3 to time t4, the processing from step S11 is repeated in the same manner as described above, all the monitoring timers are used, and the initial acceptance processing is completed. . When the initial acceptance process is completed, the process proceeds to a cold insulation monitoring process to be described later. When the next acceptance process is started, the monitoring timer for the next acceptance process is sequentially selected and set in step S9 as described above, and the same process as the first acceptance process is performed.
[0110]
Next, the cold insulation monitoring process will be described. The cold insulation monitoring process is started when the acceptance monitoring process ends. In the cold insulation monitoring process, the end of the process is determined in step S18. The end determination is determined that the cold insulation monitoring process is ended when the next receiving process is started or when milk collection is started. The signal when the next receiving process is started or when the collection of milk is started may detect the state signal of the bulk cooler 2 transmitted from the bulk cooler control means 1, or the bulk cooler control. Depending on the control state of the means 1, an operator may input a command from the keyboard 8 or press a function key to make the end determination. When the cold insulation monitoring process ends, the process ends. Otherwise, the process proceeds to step S19, where the temperature of raw milk is determined. If abnormal, the process proceeds to step S20. If normal, the process returns to step S19. Subsequently, the temperature of raw milk is determined by a comparison processing program (comparison means) in the operation monitoring control means 6.
[0111]
That is, in the step S19, the second temperature that is lower than the predetermined upper limit temperature TU and lower than the first upper limit temperature TU is equal to or higher than the first temperature TF, exceeds the lower limit temperature TL, and is higher than or equal to the lower limit temperature TL. It is determined whether the temperature is equal to or lower than the temperature TS (hereinafter referred to as a first reference), and when the first reference is reached, the process proceeds to step S20. Further, it is determined whether the temperature is equal to or higher than a predetermined upper limit temperature TU or lower than the lower limit temperature TL (hereinafter referred to as a second reference), and the process proceeds to step S20 when the second reference is reached.
[0112]
In step S20, the first monitoring information is generated at the time of the first reference, and the second monitoring information is generated at the time of the second reference, and is stored in the RAM of the operation monitoring control means 6, and the process proceeds to step S25. The processing after step S25 described in the cleaning monitoring processing is performed. In step S27, the monitoring information created in step S20 is immediately output from the operation monitoring control means 6. In the cold insulation monitoring process, the processes of step S31 and step S24 are skipped.
[0113]
Hereinafter, the operation monitoring method for monitoring the operation in the cleaning process of the bulk cooler 2 in the second embodiment will be described. In the cleaning process of the bulk cooler 2, its operation is monitored by the operation monitoring control means 6 as follows. In the cleaning monitoring step, temperature data of the cleaning liquid and drainage liquid is obtained by the temperature measuring means 4 from the start to the end of cleaning. The temperature data is stored in a RAM which is one of the data storage means of the operation monitoring control means 6. The monitoring temperature shown in FIG. 7 and stored in advance in a ROM, which is one of the data storage means, and the temperature data of the cleaning liquid and the drainage liquid in the bulk cooler 2 are compared with each other in the comparison processing program ( Comparison is made by the comparison means). The temperature of the cleaning liquid and the drained liquid is not more than a predetermined upper limit temperature TU (for example, 70 ° C for the cleaning liquid and 40 ° C for the drained liquid) and the lower limit temperature TL (for example, 65 ° C for the cleaning liquid and 35 ° C for the drained liquid). The first monitoring information is generated when the temperature exceeds the lower limit temperature TL, and the second monitoring information having a higher degree of urgency than the first monitoring information is generated when the temperature is lower than the lower limit temperature TL. Alternatively, along with the second monitoring information, information including the time of transmission, the number of transmissions, and the type of monitoring processing is transmitted to the mobile phone 11 by e-mail, and the operation of the bulk cooler 2 in the cleaning process is monitored.

The first monitoring information is created when the temperature is equal to or lower than the temperature TS. Further, second monitoring information having a higher degree of urgency than the first monitoring information is created when the temperature is not less than a predetermined upper limit temperature TU or less than a lower limit temperature TL within the time monitored by the timer. The created information is transmitted to the mobile phone 11 by e-mail together with information including the time of transmission, the number of times of transmission, and the type of monitoring process, and the operation in the receiving process of the bulk cooler 2 is monitored.
