검측지점 표시 기능을 갖는 광학용 메탄가스 검지 장치Optical methane gas detector with detection point display
본 발명은 검측지점 표시 기능을 갖는 광학용 메탄가스 검지 장치에 관한 것이며, 더욱 상세하게는 검사하고자 하는 지점을 사용자가 육안으로 확인할 수 있도록 해주는 것이다. The present invention relates to an optical methane gas detection device having a detection point display function, and more specifically to allow the user to visually check the point to be inspected.
일반적으로 특정 파장의 레이저광은 임의의 가스에 흡수되는 특징을 가지고 있다. In general, laser light having a specific wavelength has a characteristic of being absorbed by an arbitrary gas.
이러한 레이저광의 특징을 이용한 광학식 레이저 수광 장치는 원거리에서도 가스의 누출 유무를 검출할 수 있다. The optical laser receiving apparatus using the characteristics of the laser beam can detect the presence or absence of gas leakage even at a long distance.
예를 들어 설명하면, He-Ne 레이저에 의하여 조사되는 레이저광의 3.39㎛에는 3.3922㎛(λ1)와 3.3912㎛(λ2)와 같은 두 개의 파장이 존재하며 이중 λ1은 메탄에 강하게 흡수되고, λ2는 메탄에 조금밖에 흡수되지 않는 특성이 있다. For example, two wavelengths such as 3.3922 μm (λ1) and 3.3912 μm (λ2) exist at 3.39 μm of the laser light irradiated by the He-Ne laser, and λ 1 is strongly absorbed by methane and λ 2 is methane. There is a characteristic that is absorbed only slightly.
이러한 특징을 이용한 종래 레이저 기반 원격 메탄 누설 검출을 위한 방법 및 장치(미국등록특허 US 7,075,653 B1호 2006. 07. 11)는 동조 다이오드 레이저로부터 방출된 반사광을 탐지하는 광 검출기와 결합된 검출 회로 소자를 포함하는 레이저 메탄 가스 검정기가 포함되어 있다. Conventional laser-based remote methane leak detection method and apparatus (US Pat. No. 7,075,653 B1 2006. 07. 11) employs a detection circuit element coupled with an optical detector for detecting reflected light emitted from a tuning diode laser. Included is a laser methane gas analyzer.
레이저 메탄 가스 검정기는 레이저변조와 제어 신호를 합성하는 레이저 소스 모듈과 전자 모듈을 함유하는 레이저 발광 장치 서브시스템, 광 검출기, 광 검출기의 출력에서 흡수된 신호 정보를 추출하는 전자 부품을 함유한 신호 처리 모듈, 시스템 제어부, 사용자 인터페이스 모듈인 LCD 문자 디스플레이 또는 음성 출력 장치를 포함하며, 광 전송부와 문자 디스플레이와 포함시켜 손에 들 수 있는 건으로 일반적인 패키징이 된다. The laser methane gas analyzer is a laser processing module that combines laser modulation and control signals, a laser light emitting device subsystem containing an electronic module, a photo detector, and an electronic component that extracts the absorbed signal information from the output of the photo detector. It includes a module, a system control unit, an LCD character display or a voice output device, which is a user interface module, and is included in the optical transmission unit and the character display.
그리고 레이저 배터리 팩을 구비한 숄더 또는 허리 장착 장치를 더 포함하고 있다. And a shoulder or waist mounting device having a laser battery pack.
또한, 건과 숄더는 광섬유와 전선이 배꼽모양의 케이블에 의해 연결된다. In addition, the gun and shoulder are connected to the optical fiber and the wire by a navel-shaped cable.
따라서 종래 원거리에서 메탄가스의 누출 여부를 검측하는 방법은 2개의 파장을 갖는 레이저를 검측하고자 하는 지역에 조사한 후 가스에 반사되는 레이저의 파장 변화를 검사함으로써 해당 가스가 누출되는지를 판단할 수 있다. Therefore, in the conventional method for detecting the leakage of methane gas at a long distance, the laser beam having two wavelengths may be irradiated to the area to be detected, and then the change of the wavelength of the laser reflected by the gas may be determined to determine whether the gas is leaked.
상기에서와 같이 메탄가스의 누출여부를 원거리에서 검측할 수 있는 종래 광학식 메탄가스 검지 방법에 이용되는 장치는 메탄가스에 레이저를 조사한 후 메탄가스에 반사되는 레이저를 수광하는 레이저 수광 장치와, 레이저 수광 장치에 의해 수광된 레이저를 분석하는 신호 분석 장치로 구분되어 있으며, 레이저 수광 장치와 신호 분석 장치는 케이블을 통해 연결되어 있다. As described above, the apparatus used in the conventional optical methane gas detection method capable of detecting the leakage of methane gas at a long distance includes a laser light receiving device that receives a laser reflected on the methane gas after irradiating a laser to the methane gas, and a laser light receiving It is divided into a signal analysis device for analyzing the laser received by the device, the laser light receiving device and the signal analysis device is connected via a cable.

In addition, the apparatus used in the conventional optical methane gas detection method that can be detected at a long distance has a problem that it is not possible to know which point is currently detected because the detection laser is invisible.
이러한 문제점을 해결하기 위하여 원거리에서 검측할 수 있는 종래 광학식 메탄가스 검지 방법에 이용되는 장치는 가시광선 영역의 레이저(적색 또는 녹색)를 추가로 장착하여 이용하고 있다. In order to solve this problem, the apparatus used in the conventional optical methane gas detection method that can be detected from a long distance is additionally equipped with a laser (red or green) in the visible light region.
그러나 원거리에서 검측할 수 있는 종래 광학식 메탄가스 검지 방법에 이용되는 장치에 장착된 레이저 포인터는 날씨가 밝을 경우 사용자가 원거리에서 육안으로 식별하기 어려운 문제점이 있었다.
