본 발명은 고온고압 배관의 3차원 변위를 실시간으로 측정하는 고온고압 배관의 3차원 변위측정기 및 이를 이용한 감시방법에 관한 것으로, 특히 화력, 열병합, 원자력 발전소 및, 석유화학 플랜트 등에 설치되는 고온고압 배관의 3차원 변위를 실시간으로 측정하여 가동중 배관이 움직이는 위치를 정량적으로 평가하고, 위험 상황을 미리 확인하여 배관 사고를 미연에 방지할 수 있을 뿐만 아니라, 배관의 3축 변위를 측정할 수 있어 유한요소법을 통한 배관의 변형해석 및 응력해석과 비교 평가하여 배관의 거동을 예측할 수 있는 기초자료도 제공하는 고온고압 배관의 3차원 변위측정기 및 이를 이용한 감시방법에 관한 것이다.The present invention relates to a three-dimensional displacement measuring device of a high temperature and high pressure pipe for measuring the three-dimensional displacement of the high temperature and high pressure pipe in real time, and a monitoring method using the same, in particular, high temperature and high pressure pipe installed in thermal power, cogeneration, nuclear power plants, petrochemical plants, etc. By measuring the three-dimensional displacement of the pipe in real time, it is possible to quantitatively evaluate the position of the moving pipe during operation, to check the danger situation in advance, and to prevent the pipe accident in advance, as well as to measure the three-axis displacement of the pipe. The present invention relates to a three-dimensional displacement measuring apparatus for high-temperature and high-pressure pipes and a monitoring method using the same, which also provide basic data for predicting pipe behavior by comparing and evaluating the pipe deformation and stress analysis.

예를 들어 화력, 열병합, 원자력 발전소 및 각종 석유화학 플랜트 등에는 다양한 사이즈의 고온고압 파이프 배관이 설치되어 있으며, 이 고온고압 파이프 배관의 거동 변위를 항상 감시하도록 되어 있는바, 종래 고온고압 배관의 거동은 정비 기간에 배관을 지지하는 행거와 연결된 게이지 측정기로부터 배관의 초기위치를 기록한 후, 가동에 따른 배관의 거동을 이 배관의 수직방향(즉, y축의 한 방향)만을 측정함에 따라 3축 방향으로 거동하는 배관 변위를 정확하게 확인할 수 없었다.For example, thermal power plants, cogeneration, nuclear power plants, and various petrochemical plants are equipped with high-temperature, high-pressure pipe piping of various sizes. Records the initial position of the pipe from the gauge measuring instrument connected to the hanger supporting the pipe during the maintenance period, and then measures the behavior of the pipe according to its operation in the three-axis direction by measuring only the vertical direction of the pipe (ie one direction of the y-axis). It was not possible to accurately identify the behavior of the pipe displacement.

또한 종래에는 가동중 배관의 거동을 확인하기 위해서는 현장에 가서 위험한 위치에 설치된 행거의 게이지 측정기로부터 변위를 계산함으로써 배관의 처짐량 등과 같은 변위를 알 수 있기 때문에 배관의 변위측정에 상당히 불편하고, 그 데이타의 신뢰성도 문제점이 있었다.In addition, conventionally, in order to check the behavior of the pipe during operation, it is inconvenient to measure the displacement of the pipe because the displacement, such as the amount of deflection of the pipe, can be known by calculating the displacement from the gauge measuring device of the hanger installed in a dangerous position. The reliability was also a problem.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 고온고압 배관이 3축 방향으로 거동되는 정량적 자료를 얻을 수 있으면서 배관계의 유한 해석결과와 비교 평가하여 배관의 거동을 정확하게 예측할 수 있을 뿐만 아니라, 이로 인해 배관의 안정성 보장과 관리의 편이성이 향상되고, 원거리에서 배관의 거동을 모니터링할 수 있으며, 네트워크를 통해 원하는 장소에서도 확인할 수 있는 고온고압 배관의 3차원 변위측정기 및 이를 이용한 감시방법을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, it is possible to accurately estimate the pipe behavior by comparing and evaluating the results of finite analysis of the piping system while obtaining quantitative data that the high temperature and high pressure pipe behaves in three axes. In addition, this ensures the stability of pipes and improves the ease of management, monitors the behavior of the pipes at a long distance, and can monitor the desired location through the network. The purpose is to provide.

상기와 같은 목적을 달성하기 위한 본 발명은 고온고압 배관 주변에 설치되어 이 배관의 3축 거동 변위를 측정하기 위하여 수직각도와 평면각도를 측정하는 고정축에 설치되는 2개의 엔코더와 , 거리를 측정하는 변위센서, 이 변위센서를 보호하는 외형케이스로 이루어져 있다.In order to achieve the above object, the present invention is installed around a high temperature and high pressure pipe, and two encoders installed on a fixed shaft measuring vertical and plane angles in order to measure the 3-axis movement displacement of the pipe, and measure a distance. It consists of a displacement sensor and an outer case protecting the displacement sensor.

또한, 발명은 측정부에서 상기 변위측정기로부터 배관의 3축 변위를 측정하여 이를 데이타 획득 시스템을 통하여 비교검토 평가 프로그램이 설치된 중앙제어실에서 전송된 데이타를 해석결과와 비교하여 실시간으로 평가할 수 있으며, 응급시 경고 등으로 관리자에게 알려줄 수 있도록 되어 있다.In addition, the present invention can measure the three-axis displacement of the pipe from the displacement measuring unit in the measuring unit and compare it with the analysis results in real time by comparing the data transmitted from the central control room equipped with a comparative review evaluation program through the data acquisition system, The city can be notified to administrators by warnings.

이하, 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 3차원 변위측정기가 고온고압 배관에 설치된 상태도 이고, 도 2는 본 발명의 3차원 변위측정기의 상세 사시도이다.1 is a state diagram in which the three-dimensional displacement measuring instrument according to the present invention is installed in a high temperature and high pressure pipe, and FIG. 2 is a detailed perspective view of the three-dimensional displacement measuring instrument of the present invention.

본 발명에 따른 변위측정기(1)는 고온고압 배관(2) 주변에 설치되어 이 배관(2)의 3축 거동변위를 측정하기 위하여 고정축(3)에 설치되어 수직각도(φ)와 평면각도(θ)를 측정하는 2개의 엔코더(4)와 거리(r)를 측정하는 변위센서(5; LVDT(Linear Variable Differential Transformer)), 이 변위센서(5)를 보호하는 외형케이스(6)로 이루어진 구조로 되어 있다.Displacement measuring device 1 according to the present invention is installed around the high temperature and high pressure pipe (2) is installed on the fixed shaft (3) to measure the three-axis behavior displacement of the pipe (2) vertical angle (φ) and plane angle two encoders 4 for measuring (θ), a displacement sensor 5 (Linear Variable Differential Transformer (LVDT)) for measuring the distance r, and an outer case 6 for protecting the displacement sensor 5 It is structured.

이와 같이, 본 발명은 고온고압 배관의 3차원 변위를 측정하는 변위측정기(1)로서, 이 변위측정기(1)는 도 1과 같이 고온고압 배관(2) 주변에 설치된다.As described above, the present invention is a displacement measuring device 1 for measuring the three-dimensional displacement of the high temperature and high pressure pipe, the displacement measuring device 1 is installed around the high temperature and high pressure pipe 2 as shown in FIG.

그리고, 배관(2)의 거동을 평가하기 위해 이 배관(2)을 따라 유동하는 증기방향, 즉 배관(2)의 축방향은 Z축으로 정의하고, 배관(2)에 설치된 행거(8)방향, 즉 처짐이 발생되는 배관(2)의 수직방향을 Y축으로 정의하며, 오른손 법칙에 따라 X축을 정의한다.In order to evaluate the behavior of the pipe 2, the steam direction flowing along the pipe 2, that is, the axial direction of the pipe 2, is defined as the Z axis, and the hanger 8 direction provided in the pipe 2 is defined. That is, the vertical direction of the pipe (2) in which deflection occurs is defined as the Y axis, and the X axis is defined according to the right hand rule.

한편, 도 3은 배관의 3차원 변위를 측정하기 위한 변위측정기(1)의 개략적 설명을 위한 도면으로서, 공간상의 한 점을 표시함에 있어 3차원 좌표계를 사용하는데, 3차원 배관(2)의 변위를 측정하기 위해서는 원점(0)인 한 고정점과 다른 이동점(A)에 대한 거리(r)를 측정하기 위해서는 도 4와 같은 구면좌표계가 적합하다.On the other hand, Figure 3 is a view for explaining the displacement measuring device 1 for measuring the three-dimensional displacement of the pipe, a three-dimensional coordinate system is used to display a point in space, the displacement of the three-dimensional pipe (2) The spherical coordinate system as shown in FIG. 4 is suitable for measuring a distance r between one fixed point, which is the origin (0), and another moving point (A).

따라서, 도 4와 같이 원점(0)으로부터 거리(r)와 중심 평면으로부터 이동점(A)까지 수직각도(φ), 정사영면에서 수평각도(θ)가 측정되면, 공간상의 이동점(A)의 벡터를 계산할 수 있다.Therefore, as shown in FIG. 4, when the vertical angle φ from the origin 0 to the distance r and the center plane to the moving point A and the horizontal angle θ at the orthographic plane are measured, the moving point A in space is measured. We can calculate the vector of.

즉, 도 3과 같이 2개의 각(Φ, θ)과 거리(r)를 측정하게 되면, 공간상의 이동점(A)은 직교좌표를 가지게 되므로, 고정원점(0)으로부터 이동점(A)까지의 거리를 실시간으로 모니터링 하기 위해서 도 2와 같이 2개의 엔코더(4)와 변위센서(5)를 갖추면 되는 것이다.That is, when measuring the two angles (Φ, θ) and the distance r as shown in Figure 3, since the moving point A in space has a rectangular coordinate, from the fixed origin (0) to the moving point (A) In order to monitor the distance in real time, as shown in FIG. 2, two encoders 4 and displacement sensors 5 may be provided.

예를 들어, 이동점(A)은 유니버셜 조인트와 같은 지지점을 이용하여 자유모멘트(Moment Free)를 유지하게 하고, 고정원점(0)에서 2개의 엔코더(4)로부터 각도 (θ, φ)를 측정하며, 변위센서에서 거리(r)를 측정하여 상기 이동점(A)의 변위를 3차원으로 측정하게 된다.For example, the moving point A keeps the moment free using a support point such as a universal joint, and measures the angles θ and φ from two encoders 4 at a fixed origin (0). The distance r is measured by the displacement sensor to measure the displacement of the moving point A in three dimensions.

한편, 상기 변위측정기(1)는 거리(r)를 측정하기 위해 변위센서(5)를 적용하였으며, 수직각도(φ)와 수평각도(θ)를 측정하기 위해 2개의 엔코더(4)가 설치되어 있고, 내부의 변위센서 봉(7)을 보호하기 위해 알루미늄으로 가공하여 경질 도금 처리된 외형케이스(6)가 장착되어 있다.On the other hand, the displacement measuring device 1 is a displacement sensor 5 is applied to measure the distance (r), two encoders (4) are installed to measure the vertical angle (φ) and horizontal angle (θ) In order to protect the displacement sensor rods 7 therein, the outer case 6, which is hardened and processed by aluminum, is mounted.

그리고, 도 5는 본 발명에 따른 변위측정기를 이용한 변위 감시방법을 도시한 구성 블럭도로서, 배관(2)에 증기가 흐르게 되면 이 배관은 3차원 변위가 이루어지게 되고, 이를 측정부(100)의 변위측정기(1)로 감지하여 3차원 변위를 데이터 획득 시스템(102)을 통해 배관(2)을 운용하는 중앙제어실(101)로 전송시키며, 이 중앙제어실(101)의 데이터 유한해석 결과비교 프로그램(103)을 통해 실시간으로 배관(2)의 평가를 수행하여 응급상황에 대한 경고 등으로 관리자에게 인식시킬 수 있도록 되어 있다.And, Figure 5 is a block diagram showing a displacement monitoring method using a displacement measuring instrument according to the present invention, when the steam flows in the pipe (2) is a three-dimensional displacement of the pipe is made, this measuring unit 100 The three-dimensional displacement is sensed by the displacement measuring instrument 1 of the control system 101 and the data is transmitted to the central control room 101 operating the pipe 2 through the data acquisition system 102. The data finite analysis result comparison program of the central control room 101 is compared. Through 103, the evaluation of the pipe 2 is performed in real time, so that the manager can be recognized as a warning about an emergency situation.

즉, 본 발명은 고온고압 배관(2)의 3차원 변위를 측정한 데이터를 전송과 처리를 수행하기 위하여 측정된 데이터를 실시간으로 원거리 모니터링 하기 위해서는 설치된 장소로부터 데이터 획득 시스템(102; DAS(Data Acquisition System))을 통해 배관을 운용하는 중앙제어실(101)까지 연결한다. That is, the present invention provides a data acquisition system 102 (DAS) from a location where data is installed to remotely monitor the measured data in real time in order to transmit and process data measured for three-dimensional displacement of the high temperature and high pressure pipe 2. System)) to the central control room 101 that operates the pipe.

상기 데이터 획득 시스템(102)은 아날로그 신호를 디지털 신호로 전환하여 중앙제어실(101)까지 데이터의 손실 없이 원거리까지 전달되도록 구성하여야 한다. 전송방식은 데이터 측정시간 간격이 크고, 환경에 의한 데이터 손실을 최소화 하기 위해 RS232 방식과 RS485 방식을 적용하였다.The data acquisition system 102 should be configured to convert the analog signal into a digital signal to be transmitted to the central control room 101 to a long distance without loss of data. The transmission method has a large data measurement time interval, and RS232 and RS485 methods are applied to minimize data loss due to the environment.
