팬터그래프 집전판의 손상위치 검측장치{System for detecting the damaged position of Pantograph using thermal imaging camera}System for detecting the damaged position of Pantograph using thermal imaging camera}

본 발명은 팬터그래프 집전판의 검측장치에 관한 것으로, 구체적으로는 전기철도차량에 설치되어 팬터그래프의 집전판이 전차선과 접촉하여 집전 할 때 열화상 카메라를 이용하여 집전판의 발열 상태를 감시하고 집전판의 손상위치를 효과적으로 검측하는 팬터그래프 집전판의 손상위치 검측장치에 관한 것이다.The present invention relates to an apparatus for detecting a pantograph collector plate. Specifically, the present invention relates to a pantograph collector plate, and specifically, installed in an electric railway vehicle to monitor a heat generation state of a collector plate by using a thermal imaging camera when the collector plate of the pantograph is collected in contact with a vehicle line. The present invention relates to an apparatus for detecting a damage position of a pantograph collector plate which effectively detects a damage position.

전기철도차량의 집전장치인 팬터그래프에 전력을 공급하기 위하여 선로를 따라 설치한 전선로와 전선로를 지지하는 공작물을 포함하여 전차선로라고 한다. 전차선로에는 가선 방법에 따라 다양한 형태가 있으며 국내에서는 가공 전차선로가 대부분이다.It is called tram line including electric wire line installed along the line to supply electric power to pantograph which is current collector of electric railway vehicle and workpieces supporting the line. There are various types of electric railway lines depending on the method of railway line, and most of them are processed railway lines in Korea.

전기철도차량의 상부에 설치된 전차선으로부터 전기철도차량 운행에 필요한 전력을 공급받기 위하여 전기철도차량의 상측에는 전차선으로부터 공급되는 전력을 집전하는 집전판을 포함하는 팬터그래프가 설치된다.A pantograph including a current collector plate for collecting electric power supplied from an electric railway line is installed on the upper side of the electric railway vehicle in order to receive electric power required for the operation of the electric railway vehicle from an electric tank line installed on an upper portion of the electric railway vehicle.

따라서 전기철도차량은 고속으로 이동하면서 전기에너지를 전차선으로부터 공급받아야 하므로, 운행 중에 안정적으로 전기에너지 집전을 수행하기 위해서 팬터그래프의 집전판은 상기 전차선과 양호한 접촉 상태를 유지하여야 한다.Therefore, the electric railway vehicle must receive the electric energy from the electric cable while moving at a high speed. Therefore, the collector plate of the pantograph must maintain good contact with the electric wire to perform stable electric energy collection during operation.

전차선로는 팬터그래프와 양호한 접촉상태를 유지하여야 하나 전차선로의 터널 구간의 높낮이, 오버랩구간, 전기철도차량 운행에 따른 풍향, 전기철도차량의 기계적 떨림, 전차선의 파동 등 다양한 원인에 의해 기계적 비접촉 상태가 일어나게 된다.The tram line should maintain good contact with the pantograph, but the mechanical non-contact condition is caused by various reasons such as the height of the tunnel section of the tram line, the overlap section, the wind direction due to the operation of the electric railway vehicle, the mechanical vibration of the electric railway vehicle, and the wave of the tramline. Get up.

팬터그래프와 전차선 사이에 기계적인 비접촉 상태가 이루어지는 이선현상이 발생되게 됨으로써, 전차선과 팬터그래프의 집전판 사이에 전기가 순간적으로 끊어져 전기철도차량에 공급되는 전기에너지 품질이 저하될 뿐만 아니라 아크 방전이 발생하여 전차선 또는 집전판에 직접적으로 기계적 손상을 가져오게 된다.As a two-wire phenomenon occurs in which a mechanical non-contact state is generated between the pantograph and the tramline, electricity is temporarily cut off between the tramline and the current collector plate of the pantograph, thereby deteriorating the electric energy quality supplied to the electric railway vehicle and generating arc discharge. Mechanical damage will occur directly on the tank line or current collector.

이상과 같이 팬터그래프 집전판이 전차선과 접촉되어 집전하는 경우 전차선과의 집전 중 기계적 마모현상이 발생하여 전차선보다 강도가 상대적으로 약한 집전판이 마모되므로 이를 주기적으로 교환하고 있다.As described above, when the pantograph current collector plate is in contact with the tank line, the current collector plate is mechanically worn during the current collection with the tank line, and thus the current collector plate is weaker than the tank line.

이때 팬터그래프는 속도대역, 설계사양에 따라 다양한 부품으로 구분될 수 있으나, 전차선과의 접촉하는 집전판은 마모하는 소모품으로 쉽게 교환 할 수 있는 부품으로 그 재질은 카본계열, 금속-카본계열 및 금속 계열이 사용되고 있다.In this case, the pantograph can be divided into various parts according to the speed band and design specifications, but the current collector plate in contact with the electric cable line can be easily replaced with worn consumables.The material is carbon series, metal-carbon series and metal series. Is being used.

집전판과 전차선의 국부적인 마모를 방지하기 위해 상기 전차선은 시공 시에 좌우로 편위 되어 있고, 집전판은 상기 전차선으로부터 지속적인 전력을 공급받기위해 상기 전차선의 좌우 편위 넓이 이상의 넓이로 구성된다. In order to prevent local wear of the current collector plate and the catenary, the catenary is biased left and right during construction, and the collector plate is configured to have an area larger than the left and right deviations of the catenary to receive continuous power from the catenary.

따라서 팬터그래프 집전판은 전차선과의 집전시에 좌우 편위에 의해서 고르게 마모되어야 하나 집전시에 아크, 집전판의 결함, 전차선로의 편위가 고르지 않은 이유로 인해 국부적인 마모 혹은 발열이 발생 할 수 있다.Therefore, the pantograph collector plate should be worn evenly due to the left and right deviations in the current collector with the tank line, but local wear or heat generation may occur due to the arc, the defect of the current collector plate, and the irregularity of the tank line during the current collector.

또한, 팬터그래프의 집전판은 마모하는 소모품으로 교환 하도록 되어 있으나 현재 고속철도에서는 속도향상에 따라 집전판의 마모가 빠르게 발생하여 교체 주기가 빨라지고, 전기철도차량 운행 중 집전판의 국부적 마모로 인한 결함이 발생하는 등 집전판의 손상으로 인해 이선아크가 발생하는 문제점이 있다.In addition, the current collector plate of the pantograph is to be replaced with worn consumables, but in the current high-speed railway, the wear of the current collector plate occurs quickly according to the speed improvement, and the replacement cycle is accelerated, and defects are caused by local wear of the current collector plate during operation of the electric railway vehicle. There is a problem that a second arc occurs due to damage to the current collector plate.

집전판은 국부적인 마모가 아닌 전반적인 마모로 되어야 하나 국부적인 마모가 발생할 경우 전차선과의 마찰로 인해 아크나 경점이 발생하게 되는 등 문제가 발생되고 있어 이러한 국부적 마모 상태를 효율적으로 모니터링 할 수 있는 장치의 개발이 필요한 실정이다. The current collector plate should be general wear, not local wear. However, if local wear occurs, problems such as arcing or hard spots are generated due to friction with the vehicle lanes. The development of the situation is necessary.

본 발명은 상기한 사안을 감안하여 발명된 것으로 팬터그래프의 집전판의 발열 상태를 열화상카메라로 감시하여 연속적으로 발열 되는 부분을 검출하여 국부적 손상위치를 판별하는 팬터그래프 집전판의 손상위치 검측장치를 제공한다.The present invention has been made in view of the above-described problem, and provides a device for detecting a damage location of a pantograph collector plate by detecting a portion that is continuously generated by monitoring a heat generation state of a current collector plate of a pantograph by detecting a continuously generated part. do.

Characterized in that it comprises a monitoring unit.

또한, 상기 열화상카메라는 팬터그래프의 일측에 설치되어 집전판의 좌우편위 모두를 검측하도록 열적 감지를 일으킬 수 있는 가로축으로 긴 측정부분을 집중적으로 모니터링하는 것을 특징으로 한다.In addition, the thermal imaging camera is installed on one side of the pantograph is characterized by intensively monitoring the long measuring portion in the horizontal axis that can cause thermal sensing to detect both the left and right deviation of the current collector plate.

또한, 상기 모니터링부는 팬터그래프의 집전판을 상기 열화상카메라와 비디오카메라를 통해 모니터링하여 상기 집전판의 열적이상과 이선아크의 발생 위치를 동시에 판단하는 것을 특징으로 한다.The monitoring unit may monitor the current collector plate of the pantograph through the thermal imaging camera and the video camera to simultaneously determine the thermal abnormality of the current collector plate and the occurrence position of the second arc.

또한, 상기 모니터링부는 상기 팬터그래프의 측정부분 중 국부적으로 연속적인 열이 발생될 경우 자동으로 국부 범위를 누적 기록하고, 설정된 누적 한계값을 넘는 국부 범위를 판단하여 알람하는 것을 특징으로 한다.The monitoring unit may automatically accumulate and record a local range when a local continuous heat is generated among the measurement portions of the pantograph and determine a local range exceeding a set cumulative limit value to alarm.

본 발명의 팬터그래프 집전판의 손상위치 검측장치에 의하면, 전기철도차량 운행 중에 팬터그래프 집전판의 발열 상태를 연속적으로 검측하여 집전판의 측정 부분 중 발열이 연속적으로 나는 부분을 판단하여 사전에 집전판의 손상을 방지 할 수 있다.According to the apparatus for detecting the damage position of the pantograph collector plate of the present invention, the heating state of the pantograph collector plate is continuously detected during the operation of an electric railway vehicle to determine a portion of the measurement plate of the collector plate that generates heat continuously in advance. It can prevent damage.

또한 전기철도차량의 속도가 향상됨에 따라 빠르게 진행하는 팬터그래프의 집전판의 부분마모, 크랙 등을 전기철도차량 운행 중에 판별이 가능하고, 운행 후 필요시 의심 되는 부분의 점검을 용이하게 할 수 있다.In addition, as the speed of the electric rail vehicle is improved, partial wear and cracks of the current collector plate of the pantograph which are rapidly progressing can be discriminated during the operation of the electric rail vehicle, and the inspection of the suspected parts can be facilitated if necessary after the operation.

우선 도 1에 도시된 바와 같이, 본 발명에 의한 팬터그래프 집전판의 손상위치 검측장치는 전기철도차량 상부에 팬터그래프의 일측에 설치되어 상기 팬터그래프의 집전판을 촬영하는 열화상카메라(110) 및 비디오카메라(120)를 구비하고, 전기철도차량 내부에 전기철도차량의 속도 및 운행거리를 획득하는 DAQ(210)와 상기 DAQ(210), 열화상카메라(110) 및 비디오카메라(120)의 출력 값을 신호처리 후 상기 신호처리한 데이터를 송신안테나를 통하여 무선 송신하는 컨트롤러(220)를 구비하며, 전기철도차량 외부에 상기 컨트롤러(220)로부터 수신받은 신호처리된 데이터를 분석하여 팬터그래프의 이상 발열 상태를 검측하는 모니터링부(300)를 포함하여 이루어진다.First, as shown in Figure 1, the damage position detection apparatus of the pantograph collector plate according to the present invention is installed on one side of the pantograph on the top of the electric railway vehicle to shoot the thermal imaging camera 110 and the video camera to photograph the collector plate of the pantograph (120) and output values of the DAQ (210) and the DAQ (210), the thermal imaging camera (110) and the video camera (120) for acquiring the speed and travel distance of the electric railway vehicle in the electric railway vehicle. And a controller 220 for wirelessly transmitting the signal processed data through a transmission antenna after signal processing, and analyzing the signal processed data received from the controller 220 outside the electric railway vehicle to determine an abnormal heat generation state of the pantograph. It comprises a monitoring unit 300 to detect.

상기 열화상카메라(110)는 전기철도차량 상부에 팬터그래프의 집전판을 향하여 전기철도차량 운행방향의 전방 또는 후방에 설치되어 상기 팬터그래프의 열적 이미지를 촬영한다. The thermal imaging camera 110 is installed in the front or rear of the electric railway vehicle running direction toward the current collector plate of the pantograph on the electric railway vehicle to take a thermal image of the pantograph.

도 2는 팬터그래프의 일측에서 상기 팬터그래프를 촬영하는 상기 비디오카메라(120)의 촬영 영상으로 가로 세로 축의 눈금자를 통하여 이선아크에 발생 지점을 나타내준다. FIG. 2 is a photographed image of the video camera 120 photographing the pantograph on one side of the pantograph, and shows a generation point on the second arc through the ruler of the horizontal and vertical axes.

그러나 상기 집전판은 크랙이나 국부 마모가 되면 집전 시 뿐만 아니라 전차선이 접촉하지 않는 이선시에도 열이 발생하게 되므로 열적 이미지 분석을 통한 집전판의 마모를 확인 할 필요성이 있다.However, when the current collector plate is cracked or locally worn, heat is generated not only at the time of current collection but also at the second wire where the electric vehicle lines do not contact, so it is necessary to confirm the wear of the current collector plate through thermal image analysis.

따라서 상기 비디오카메라(120)는 이러한 집전판과 전차선이 동적으로 접촉하는 모든 면 중에서 특히 아크가 많이 발생하는 곳을 검측하기 위해 사용하고, 상기 열화상카메라는(110)는 열화상은 열적으로 균일하지 못한 면을 찾아 이를 비교하여 집전 상태 모니터링 혹은 집전판의 이상여부를 판단할 수 있다.Therefore, the video camera 120 is used to detect a lot of arcs occur especially in all the surfaces in which the current collector plate and the chariot line is in dynamic contact, the thermal imaging camera 110 is thermally uniform thermal By finding and comparing the failures, it is possible to monitor the current collector status or determine whether the current collector board is abnormal.

또한 상기 집전판은 크랙이나 국부 마모가 되면 집전 시 뿐만 아니라 전차선이 접촉하지 않을 때에도 열이 발생하게 되므로, 상기 열화상카메라(110)는 팬터그래프의 전방 또는 후방에 설치하여 집전 시 집전판에서 발생하는 아크를 모니터링 하는 것이 아니라 국부적으로 온도가 가장 높은 부분을 판단하는 기능을 한다.In addition, since the current collector plate is cracked or worn out locally, heat is generated not only at the time of current collection but also when the electric cable is not in contact with the current collector plate. Rather than monitoring the arc, the function is to determine the highest temperature locally.

상기 열화상카메라(110)는 상기 집전판의 좌우편위 모두를 검측하도록 충분한 이격거리와 민감도를 갖도록 설치되어야 한다.The thermal imaging camera 110 should be installed to have sufficient separation distance and sensitivity to detect both left and right deviations of the current collector plate.

이 경우 상기 집전판은 그 길이가 좌우로 300mm 이상이고, 상기 집전판과 접촉하는 전차선은 그 접촉되는 부위의 편위가 좌우 200mm 이며, 전차선과 집전판이 접촉하여 달리는 동안은 좌우편위의 한계값은 250mm 로 측정된다.In this case, the current collector plate has a length of 300 mm or more in the left and right, the tank line in contact with the current collector plate has a left and right deviation of 200 mm, the limit value of the left and right deviation while the tank line and the current collector plate is running in contact with Is measured.

따라서 상기 열화상카메라(110)는 도 3에 도시된 바와 같이, 팬터그래프의 열적 감지를 일으킬 수 있는 가로축으로 긴 점선으로 표시된 측정부분(A)을 집중적으로 촬영할 수 있도록 조정하는 것이 바람직하다.Therefore, as shown in FIG. 3, the thermal imaging camera 110 may be adjusted to intensively photograph the measurement portion A indicated by a long dotted line on the horizontal axis, which may cause thermal sensing of the pantograph.

상기 모니터링부(300)는 전기철도차량 상부에 설치한 상기 열화상카메라(110)를 현시하고 실시간으로 모니터링하는데, 이때 상기 모니터링부(300)는 팬터그래프의 측정부분(A)에서 국부적으로 연속적인 열이 발생될 경우 자동으로 국부 범위를 누적 기록하게 되고, 이때 설정된 누적 한계값을 넘는 수치의 국부 범위를 신속하게 알람하여 필요시 전기철도차량에 운행 이후 점검할 수 있다.The monitoring unit 300 manifests and monitors the thermal imaging camera 110 installed in the upper portion of the electric railway vehicle in real time, wherein the monitoring unit 300 is a local continuous heat in the measuring portion (A) of the pantograph. If this occurs, the local range is automatically recorded and accumulated, and at this time, the local range of the value exceeding the set cumulative limit value can be quickly alarmed and checked after operation in the electric railway vehicle if necessary.
