【発明の属する技術分野】
本発明は、発電所や各種プラントに設備された配管や機器等の設備の空間的位置（３次元座標）を計測することによって設備の健全性を評価する設備健全性評価方法と評価装置、及び同装置によって得られた３次元座標を用いて行う設備補修工法に関する。
【０００２】
【従来の技術】
発電プラント等には、配管や機器等の設備が多数設置されている。これらの設備は、運転中の熱や負荷によって生じる応力や変形が許容値以内にあることを確認する必要がある。
【０００３】
この確認は従来、配管・機器の解析モデルを作成し、計算機による解析によって行われている。しかしながら、解析を実施する際には、配管・機器の座標データ誤差、解析上の仮定等により算出結果も、誤差を含んでいる可能性があるため、発生応力や変形を正確に知ることは困難である。
【０００４】
【発明が解決しようとする課題】
本発明は、上記課題を解決するためになされたもので、配管・機器等の設備運転中の熱や負荷によって生じる移動量と応力を正確に知ることのできる設備健全性評価方法及び評価装置、及びこの評価方法または評価装置を用いた設備補修工法を提供することを目的とする。
【０００５】

【０００６】

【０００７】
請求項３の発明は、設備健全性評価装置に関する発明であって、所定室を含む複数の室にわたって設置される設備と、運転中及び停止中の前記設備の形状に関する画像データと前記設備上に設定された座標基準点の３次元座標とを入力される入力部と、前記画像データと前記基準座標点３次元座標から前記設備上の評価点の３次元座標を算出し設備運転中の評価点の３次元座標と設備停止中の評価点の３次元座標から評価点の移動量を算出しこの移動量によって設備の健全性を判定する演算・判定部と、判定の結果を表示する表示部と、前記基準座標点の３次元座標と評価点の３次元座標を保存する保存部とを備えた設備健全性評価装置において、前記所定室の開口部に、所定室内３次元座標と所定室外３次元座標とを関連付ける３次元座標連結点を設けることを特徴とする。
【００１４】
【発明の実施の形態】
図１〜図９を参照して本発明の第１の実施の形態を説明する。図１は本実施の形態の設備健全性評価方法を示す流れ図であり、図２は設備健全性評価装置のハードウエア構成図である。
図１に示すように、まず画像データ取得装置、例えばフィルムカメラ，デジタルカメラ等により設備の画像データを取得する（ステップＳＡ１）。
【００１５】
次に例えば図３に示す座標基準装置を設備の表面に設置して座標基準点を設定する（ステップＳＡ２）。なお、本座標基準装置は、次のステップにて行う３次元座標取得を容易に行えるような図柄を有している。
【００１６】
次に、座標基準点の３次元座標を、角測量法原理を利用した測量装置セオドライトや、巻尺等による測定により算出する（ステップＳＡ３）。
ステップＳＡ１で取得された設備の画像データと、ステップＳＡ３で算出された座標基準点３次元座標は、図２に示した設備健全性評価装置の入力部１に入力される。
【００１７】
次に、設備健全性評価装置の演算・判定部２において、座標基準点の３次元座標を基準として、画像データ取得装置にて取得された画像データ内の設備上の評価点３次元座標を算出する（ステップＳＡ４）。評価点は健全性評価の必要に応じて設備上に１個ないし複数とる。
【００１８】
ここで図４を参照して、３次元座標取得のための写真測量法を説明する。図４に示すように対象物１，２，３が配置されており、対象物３の点Ａの３次元座標を算出するものとする。
【００１９】
まず、カメラ位置１，２において、対象物の写真を撮影する。その時、対象物は、図に示すように写真１，２上に投影される。
図５に示すように、写真１，２上の点に座標系（Ｘ1 ，Ｙ1 ）、（Ｘ2 ，Ｙ2 ）を取る。そして、写真１，２の座標系（Ｘ1 ，Ｙ1 ）、（Ｘ2 ，Ｙ2 ）を含む全体の座標系を（Ｘ，Ｙ，Ｚ）とする。カメラの焦点距離をｆ、カメラ１とカメラ２とのＸ方向の距離をαとすると、写真１の座標系原点は全体座標系では（０，０，ｆ）、写真２の座標系原点は全体座標系では（α，０，ｆ）に位置することになる。他方、写真１上のＢ1 点と写真２上のＢ2 点の座標を、それぞれの写真座標上でＢ１（ｘ1 ，ｙ1 ），Ｂ2 （ｘ2 ，ｙ2 ）とすると、全体座標系では、Ｂ1 （ｘ1 ，ｙ1 ，ｆ），Ｂ２（ｘ2 ，ｙ2 ，ｆ）となる。
【００２０】
図５において、点Ｂ2 を写真１上に平行移動させた点をＢ2 ’とすると、三角形Ｏ1 Ｂ1 Ｂ2 ’と三角形ＡＯ1 Ｏ2 は相似であるので、座標間に以下の関係が成り立つ。
【００２１】
【数１】

Figure 0003837259
【００２２】
以上のように、カメラの焦点距離ｆ及びカメラ位置間隔αが分かっており、点Ｂ1 と点Ｂ2 の写真上での座標が求められれば、Ａ点の３次元座標を算出することができる。
このようにして算出された設備上の評価点の３次元座標は、健全性評価装置の保存部３に保存される（ステップＳＡ５）。
【００２３】
図６に停止中及び運転中の設備の状態を示す。運転中は、例えば配管内流体の温度が上昇するため、設備は停止状態とは異なった形状になり、評価点の座標値が変化する。そこで、図６に示すように、適切な位置に評価点を予め設定し、それらの評価点の停止中のデータを全て取得しておき、健全性評価装置の保存部３に保存しておく。その後、運転状態での全評価点の座標値を取得し、同様に保存部３に保存する（ステップＳＡ５）。
図７に保存部３に保存される設備の停止中及び運転中の評価点の３次元座標データ例を示す。
【００２４】
次に、保存部３に保存された停止中及び運転中の３次元座標データを演算・判定部２にて比較し、運転中座標−停止中座標＝移動量 の算術式から移動量を算出する（ステップＳＡ６）。この移動量によって設備の健全性を判定する場合には、図１のステップＳＡ７，８を経ずに、この移動量を表示部４に表示する（ステップＳＡ９）。表示例を図８に示す。
応力によって判定する場合には、演算・判定部２において有限要素法等を使用して、評価点の移動量から設備の応力を算出する（ステップＳＡ７）。
【００２５】
次に、上記にて算出された各評価点における発生応力と設備の材料、使用温度等から決定される許容応力とを、演算・判定部２において比較して判定し（ステップＳＡ８）、発生応力が許容応力を上回っていれば、設備が危険な状態である可能性が高いとして、表示部４に表示し操作者に光，音等によるアラームを発して設備の状態確認を促す（ステップＳＡ９）。算出された応力値と許容応力及び判定の表示例を図９に示す。
【００２６】
次に、図10を参照して本発明の第２の実施の形態を説明する。この図に示されたステップＳＢ１からＳＢ６までは図１に示されたステップＳＡ１からＳＡ７までと同じである。本実施の形態においては、図２に示した演算・判定部２に３次元ＣＡＤデータ作成機能と３次元ＣＡＤ応力判定機能を持たせる。
【００２７】
このような構成とした設備健全性評価方法及び装置により、運転中及び停止中の設備の３次元座標を保存部３から受け取り、設備の３次元ＣＡＤデータを演算・判定部２にて作成する（ステップＳＢ７）。また、演算・判定部２において設備に発生している応力を算出し（ステップＳＢ６）、その結果と前記の３次元ＣＡＤデータを用いて３次元ＣＡＤ応力を判定する（ステップＳＢ８）。表示部４は、許容応力を上回っている設備部位の色を変化させ表示し（ステップＳＢ９）、操作者へ視覚的に伝達する。
【００２８】
次に図11を参照して本発明の第３の実施の形態を説明する。本実施の形態においては、前述した設備の３次元座標取得に写真測量法ではなくレーザ光線を用いる。すなわち、レーザ光線を設備へ発射しその反射光を受信することにより、そのレーザ発射角度と反射レーザ受信角度、及びレーザ発射位置とレーザ受信位置の距離から三角測量法を用いて、設備の３次元座標を算出する。このようにすることにより、座標基準装置の設置が困難である高所部や高放射線量のため人間が近づけない場所等についても、設備の３次元座標を取得することができる。
【００２９】
座標基準装置は、図12に符号５として示すように設備に塗装等として予め取り付けておくことにより、座標基準装置の設置が困難である高所部や高放射線量により人間が近づけない場所等についても、設備の３次元座標を取得することができる。
【００３０】
図13に本発明の第５の実施の形態を示す。
プラント内に設置される配管はプラント内の密閉空間である各室を貫通し、ポンプ，弁等の機器に接続されている。このような場合、各室に設置された設備は、各室における３次元座標空間とプラント全体における３次元座標空間を有している。しかし通常、設備の３次元座標測定は各室毎の座標を基に実施されており、異なる室に設置されている設備の座標は関連づけられていない。このため、ポンプ等の交換により配管配置を変更する際に室の内外を貫通している配管の位置を正確に合わせることは困難である。
【００３１】
そこで本実施の形態においては、所定室の開口部に座標基準装置５の取り付けられた３次元座標連結点を設け、所定室内外から画像データを取り込み、連結点の３次元座標を内外の座標空間の関連づけに使用する。このようにすることによって所定室内外の３次元座標を統合することができる。また、このように３次元座標連結点を設けることにより、所定室の内外にわたって設置されている設備の補修に際して配管や機器の位置合わせを容易に行うことができる。
【００３２】
図14に第６の実施の形態を示す。本実施の形態は校正装置に関する。
図14に示す校正装置はＬ1 、Ｌ2 、Ｈ寸法を予め厳密に測定されており、設備健全性評価の前に、校正装置のＬ1 、Ｌ2 、Ｈ寸法を設備健全性評価装置にて測定し、予め測定されている寸法と比較を行い、設備健全性評価装置の校正を行う。こうすることによって、設備の形状を正確に測定し、健全性について正しい判定を下すことができる。
【００３３】
【発明の効果】
本発明によれば、プラント停止中及び運転中の設備の３次元座標から設備の移動量を算出し、またその移動量から設備に発生している応力を求め許容応力値と比較するので、設備の健全性を正確に評価することができプラントの信頼性向上を図ることができる。

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a flowchart showing a facility soundness evaluation method according to the present embodiment, and FIG. 2 is a hardware configuration diagram of a facility soundness evaluation apparatus.
As shown in FIG. 1, first, image data of equipment is acquired by an image data acquisition device such as a film camera or a digital camera (step SA1).
[0015]
Next, for example, the coordinate reference device shown in FIG. 3 is installed on the surface of the equipment to set the coordinate reference point (step SA2). In addition, this coordinate reference | standard apparatus has a pattern which can perform the three-dimensional coordinate acquisition performed at the next step easily.
[0016]
Next, the three-dimensional coordinates of the coordinate reference point are calculated by measurement using a surveying device theodolite using the principle of angle surveying, a tape measure, or the like (step SA3).
The equipment image data acquired in step SA1 and the coordinate reference point three-dimensional coordinates calculated in step SA3 are input to the input unit 1 of the equipment soundness evaluation apparatus shown in FIG.
[0017]
Next, the calculation / determination unit 2 of the equipment soundness evaluation apparatus calculates the evaluation point three-dimensional coordinates on the equipment in the image data acquired by the image data acquisition apparatus based on the three-dimensional coordinates of the coordinate reference point. (Step SA4). One or more evaluation points are taken on the facility as necessary for soundness evaluation.
[0018]
Here, referring to FIG. 4, a photogrammetry method for obtaining three-dimensional coordinates will be described. As shown in FIG. 4, the objects 1, 2, and 3 are arranged, and the three-dimensional coordinates of the point A of the object 3 are calculated.
[0019]
First, a photograph of the object is taken at camera positions 1 and 2. At that time, the object is projected onto the photographs 1 and 2 as shown in the figure.
As shown in FIG. 5, coordinate systems (X 1 , Y 1 ) and (X 2 , Y 2 ) are taken at points on the photographs 1 and 2. The entire coordinate system including the coordinate systems (X 1 , Y 1 ) and (X 2 , Y 2 ) of the photos 1 and 2 is defined as (X, Y, Z). If the focal length of the camera is f and the distance between the camera 1 and the camera 2 in the X direction is α, the origin of the coordinate system of Photo 1 is (0, 0, f) in the global coordinate system, and the origin of the coordinate system of Photo 2 is the whole. In the coordinate system, it is located at (α, 0, f). On the other hand, the coordinates of B 1 point on Picture 1 and Picture 2 on the B 2 points, B1 on each photo coordinates (x 1, y 1), the B 2 (x 2, y 2) to the entire coordinates In the system, B 1 (x 1 , y 1 , f) and B 2 (x 2 , y 2 , f) are obtained.
[0020]
5, 'When, triangle O 1 B 1 B 2' points obtained by translating the point B 2 on Photo 1 B 2 because the triangle AO 1 O 2 is a similar, the following relationship between coordinates Holds.
[0021]
[Expression 1]
Figure 0003837259
[0022]
As described above, if the focal length f and the camera position interval α of the camera are known and the coordinates of the points B 1 and B 2 on the photograph are obtained, the three-dimensional coordinates of the point A can be calculated. .
The three-dimensional coordinates of the evaluation points on the equipment thus calculated are stored in the storage unit 3 of the soundness evaluation apparatus (step SA5).
[0023]
FIG. 6 shows the state of the equipment during stoppage and operation. During operation, for example, since the temperature of the fluid in the pipe rises, the equipment has a shape different from that in the stopped state, and the coordinate value of the evaluation point changes. Therefore, as shown in FIG. 6, evaluation points are set in advance at appropriate positions, and all data at the time when the evaluation points are stopped are acquired and stored in the storage unit 3 of the soundness evaluation apparatus. Thereafter, the coordinate values of all evaluation points in the operating state are acquired and similarly stored in the storage unit 3 (step SA5).
FIG. 7 shows an example of three-dimensional coordinate data of evaluation points stored in the storage unit 3 while the equipment is stopped and in operation.
[0024]
Next, the calculation / determination unit 2 compares the three-dimensional coordinate data stored in the storage unit 3 while stopped and during operation, and calculates the amount of movement from the arithmetic expression of coordinates during operation-coordinate during stop = movement amount. (Step SA6). When determining the soundness of the facility based on the amount of movement, the amount of movement is displayed on the display unit 4 without going through steps SA7 and SA8 in FIG. 1 (step SA9). A display example is shown in FIG.
When determining by the stress, the calculation / determination unit 2 uses the finite element method or the like to calculate the stress of the equipment from the amount of movement of the evaluation point (step SA7).
[0025]
Next, the calculation / determination unit 2 compares and determines the generated stress at each evaluation point calculated above and the allowable stress determined from the material of the equipment, the operating temperature, and the like (step SA8). If the value exceeds the allowable stress, it is considered that the equipment is likely to be in a dangerous state, and the information is displayed on the display unit 4 and an alarm by light, sound, etc. is issued to the operator to prompt the equipment status confirmation (step SA9). . A display example of the calculated stress value, allowable stress, and determination is shown in FIG.
[0026]
Next, a second embodiment of the present invention will be described with reference to FIG. Steps SB1 to SB6 shown in this figure are the same as steps SA1 to SA7 shown in FIG. In the present embodiment, the calculation / determination unit 2 shown in FIG. 2 has a three-dimensional CAD data creation function and a three-dimensional CAD stress determination function.
[0027]
With the equipment soundness evaluation method and apparatus configured as described above, the three-dimensional coordinates of the running and stopped equipment are received from the storage unit 3, and the three-dimensional CAD data of the equipment is created by the calculation / determination unit 2 ( Step SB7). Further, the stress generated in the equipment is calculated in the calculation / determination unit 2 (step SB6), and the three-dimensional CAD stress is determined using the result and the three-dimensional CAD data (step SB8). The display unit 4 changes and displays the color of the facility part that exceeds the allowable stress (step SB9), and visually transmits it to the operator.
[0028]
Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, a laser beam is used instead of the photogrammetry method for acquiring the three-dimensional coordinates of the equipment described above. That is, by emitting a laser beam to the equipment and receiving the reflected light, the three-dimensional measurement of the equipment is performed using the triangulation method from the laser emission angle and the reflected laser reception angle, and the distance between the laser emission position and the laser reception position. Calculate the coordinates. By doing so, it is possible to acquire the three-dimensional coordinates of the equipment even at a high place where it is difficult to install the coordinate reference device or a place where a human cannot approach due to a high radiation dose.
[0029]
As shown by reference numeral 5 in FIG. 12, the coordinate reference device is attached to the equipment in advance as a paint or the like, so that it is difficult to install the coordinate reference device or places where humans cannot approach due to a high radiation dose. Also, the three-dimensional coordinates of the equipment can be acquired.
[0030]
FIG. 13 shows a fifth embodiment of the present invention.
Piping installed in the plant penetrates each chamber, which is a sealed space in the plant, and is connected to equipment such as a pump and a valve. In such a case, the equipment installed in each room has a three-dimensional coordinate space in each room and a three-dimensional coordinate space in the entire plant. However, usually, the three-dimensional coordinate measurement of equipment is performed based on the coordinates of each room, and the coordinates of equipment installed in different rooms are not related. For this reason, it is difficult to accurately align the position of the pipe penetrating the inside and outside of the chamber when the pipe arrangement is changed by exchanging the pump or the like.
[0031]
Therefore, in the present embodiment, a three-dimensional coordinate connection point to which the coordinate reference device 5 is attached is provided at an opening of a predetermined room, image data is taken in from the outside of the predetermined room, and the three-dimensional coordinates of the connection point are set in an internal and external coordinate space. Used for association. By doing so, the three-dimensional coordinates inside and outside the predetermined room can be integrated. In addition, by providing the three-dimensional coordinate connection point in this way, it is possible to easily align the pipes and equipment when repairing the facilities installed inside and outside the predetermined chamber.
[0032]
FIG. 14 shows a sixth embodiment. The present embodiment relates to a calibration apparatus.
Calibration apparatus shown in FIG. 14 is previously precisely measured L 1, L 2, H dimensions, prior to the equipment integrity assessment, the L 1, L 2, H dimensions of the calibration device to the equipment integrity assessment device Then, compare with the pre-measured dimensions and calibrate the equipment soundness evaluation device. By doing so, it is possible to accurately measure the shape of the equipment and make a correct judgment on soundness.
[0033]
【The invention's effect】
According to the present invention, the amount of movement of the equipment is calculated from the three-dimensional coordinates of the equipment when the plant is stopped and in operation, and the stress generated in the equipment is obtained from the amount of movement and compared with the allowable stress value. It is possible to accurately evaluate the soundness of the plant and improve the reliability of the plant.
