Description

本発明は、各種プラント機器からなるプラントの３次元ＣＡＤモデルの作成システム及び作成方法に関する。   The present invention relates to a creation system and creation method for a three-dimensional CAD model of a plant composed of various plant devices.

各種プラント、例えば、原子力プラントは、加熱冷却機器、配管、弁、ポンプ、サポート等の各種プラント機器を有し、それらのプラント機器が相互に接続されプラントを構成している。   Various plants, for example, nuclear power plants, have various plant equipment such as heating / cooling equipment, piping, valves, pumps, and supports, and these plant equipments are connected to each other to constitute a plant.

このようなプラントを設計する際、複数のプラント機器の配置設計は、各プラント機器の設計情報をもとに、３次元ＣＡＤ作成システムにより３次元ＣＡＤモデルを作成することによりおこなわれている。   When designing such a plant, the layout design of a plurality of plant devices is performed by creating a three-dimensional CAD model by a three-dimensional CAD creation system based on design information of each plant device.

一方、これらのプラント機器を現場に設置した後、３次元計測装置により設置されたプラント機器を計測し、プラント機器の設置状況を確認することがおこなわれている。その際、設計時の３次元ＣＡＤモデルが３次元計測装置により計測されたプラント機器の位置情報と異なる場合は、設計時の３次元ＣＡＤモデルを修正することもおこなわれている（特許文献１）。   On the other hand, after these plant devices are installed on site, the plant devices installed by a three-dimensional measuring device are measured to check the installation status of the plant devices. At that time, when the 3D CAD model at the time of design is different from the position information of the plant equipment measured by the 3D measuring device, the 3D CAD model at the time of design is also corrected (Patent Document 1). .

この実測３次元位置データにより修正された３次元ＣＡＤモデルは、プラント改造検討時に周囲の構造物と計画中の構造物との干渉チェック、搬出入ルートの確認に利用可能であり、プラント改造計画の一助となっている。   The 3D CAD model corrected by the measured 3D position data can be used to check the interference between surrounding structures and the planned structure and to check the loading / unloading route when considering plant remodeling. It has helped.
