プラントに設置された計器室に接続される一次側ケーブルと、前記プラントに設置された複数の機器にそれぞれ接続される複数の二次側ケーブルとを中継する複数の中継器の配線設計を支援するプラント設計支援装置であって、
前記プラントの配置図における、前記計器室の設置位置、前記機器の設置位置、及び、前記一次側ケーブルが設置可能な領域を示す一次側ケーブル設置領域をプラント設計情報として取得するとともに、前記中継器の配線設計に関する中継器配線設計条件を取得する情報取得部と、
前記情報取得部にて取得された前記プラント設計情報及び前記中継器配線設計条件に基づいて、前記配置図における前記中継器の設置位置と、前記中継器に接続される前記機器の割当とを決定する決定部と、を備える。
図1は、プラント設計支援システム1及びプラント10の一例を示す全体図である。プラント設計支援システム1は、プラント10の設計、特にプラント10に設置される中継器14の配線設計を支援するためのシステムとして機能する。プラント10は、例えば、天然ガスプラント、石油精製プラント、化学処理プラント、発電プラント、製鉄プラント等の任意のプラントであり、これらの例に限られない。
図2は、プラント設計支援装置2の一例を示すブロック図である。プラント設計支援装置2は、プロセッサ等により構成される制御部20と、HDD、SSD、メモリ等により構成される記憶部21と、ネットワーク4との通信インターフェースである通信部22と、キーボード、マウス等により構成される入力部23と、ディスプレイ等により構成される表示部24とを備える。なお、入力部23及び表示部24は省略されてもよい。
以下、プラント設計支援システム1による一連の動作について説明する。一連の動作は、プラント設計支援装置2の各部(プラント設計支援プログラム210により実行されるプラント設計方法の各工程)と、設計者端末装置3とが連携することで実行される。
本発明は上述した実施形態に制約されるものではなく、本発明の主旨を逸脱しない範囲内で種々変更して実施することが可能である。そして、それらはすべて、本発明の技術思想に含まれるものである。
図16は、中継器配線設計処理の第1の変形例を示す機能説明図である。第1の変形例では、ステップS1331にて、決定部202が、一次側ケーブル設置領域の外形線101と、仮想枠100とが交差する2つの交点102同士を結ぶことで交差線分103を機器13毎に生成する際、図16に示す機器13F、13Gのように、交差線分103F、103Gを一次側ケーブル設置領域の外形線101に沿って生成する。そのため、機器13Gに対する交差線分103Gは、図16に示すように、外形線101の角部分に沿うように2つの交点102Gが結ばれることで折れ線状に生成される。なお、外形線101が湾曲部分を有する場合には、交差線分103は、湾曲状に生成されてもよい。また、図16の例では、重複線分104Cは、直線状に生成されているが、複数の交差線分103が角部分や湾曲部分で重複している場合には、重複線分104Cについても折れ線状や湾曲状に生成されてもよい。
図17は、中継器配線設計処理の第2の変形例を示す機能説明図である。上記実施形態では、ステップS1331にて、交差線分103は、一次側ケーブル設置領域の外形線101と、仮想枠100とが交差する2つの交点102同士を結ぶことで生成されるものとして説明した。その際、交差線分103は、機器13と同じ側に位置する一次側ケーブル設置領域の外形線101と、仮想枠100とが交差する交点(同じ側の交点)同士を結ぶことで機器13と同じ側に生成されてもよいし、機器13と反対側に位置する一次側ケーブル設置領域の外形線101と、仮想枠100とが交差する交点(反対側の交点)同士を結ぶことで機器13と反対側に生成されてもよい。その結果として、中継器14の設置位置P2は、機器13に対して一次側ケーブル設置領域と同じ側に決定されてもよいし、機器13に対して一次側ケーブル設置領域と反対側に決定されてもよい。
図18は、中継器配線設計処理の第3の変形例を示す機能説明図である。第3の変形例では、ステップS1333にて、決定部202が、機器グループ105毎に重複線分104の内側に中継器14の設置位置P2を決定する際、機器グループ105に含まれる複数の機器13を中継器14にそれぞれ接続したときの二次側ケーブル16の長さを合計した合計値に基づいて、中継器14の設置位置P2を決定する。そのため、図18に示す機器13A~13Cに対する中継器14Eの設置位置P2は、図10に示す中継器14Aの設置位置P2(重複線分104Aの中点)に比較して、機器13C側に設置される。なお、決定部202は、二次側ケーブル16の各ケーブル長さを合計した合計値が短くなるように中継器14の設置位置P2を決定してもよい。さらに、決定部202は、その合計値が最小値となるように中継器14の設置位置P2を決定してもよい。
図19は、中継器配線設計処理の第4の変形例を示す機能説明図である。第4の変形例では、一次側ケーブル設置領域のうち、中継器14を設置することを禁止する領域を示す中継器設置禁止領域106が、例えば、プロットプラン図500に記録される。そして、決定部202は、その中継器設置禁止領域106を除外した一次側ケーブル設置領域に対して中継器14の設置位置P2を決定する。
図20は、中継器配線設計処理の第5の変形例を示す機能説明図である。上記実施形態では、その他の処理例として、決定部202が、信号の属性毎に、中継器14の設置位置P2と、機器13の割当とを決定するものとして説明した。第5の変形例では、一次側ケーブル設置領域に対して設置可能な信号の属性を示す設置可能信号属性が、例えば、プロットプラン図500に記録される。そして、決定部202は、一次側ケーブル設置領域に対して設定された設置可能信号属性が示す信号の属性に対応する一次側ケーブル15がその一次側ケーブル設置領域に設置されるように、中継器14の設置位置P2と、機器13の割当とを決定する。
図21は、中継器配線設計処理の第6の変形例を示す機能説明図である。第6の変形例では、二次側ケーブル16を設置することが禁止された領域を示す二次側ケーブル設置禁止領域107が、例えば、プロットプラン図500に記録される。そして、決定部202は、その二次側ケーブル設置禁止領域107を二次側ケーブル16が通過しないように、中継器14の設置位置P2を決定する。
