Title (EN) GAS DETECTION DEVICE AND GAS DETECTION METHOD
(FR) DISPOSITIF DE DÉTECTION DE GAZ ET PROCÉDÉ DE DÉTECTION DE GAZ
(JA) ガス検知装置及びガス検知方法
Abstract:
(EN) A gas detection unit, a distance measurement unit, and an altitude control unit are disposed in an unmanned flying body. The gas detection unit emits to the front and diagonally downward, looking from the travel direction of the unmanned flying body, detection light that is frequency modulated by a predetermined modulation frequency having a predetermined frequency as the center frequency. The gas detection unit, from the emission of the detection light, receives as first light the light that has returned from a measurement location (a location irradiated by the detection light in a tubular member for gas transportation), and inspects a gas leak at the measurement location on the basis of the received first light. The distance measurement unit measures the distance between the gas detection unit and the measurement location. The altitude control unit controls the flying altitude of the unmanned flying body on the basis of the measured distance.
(FR) L'invention concerne une unité de détection de gaz, une unité de mesure de distance, et une unité de commande d'altitude qui sont placées dans un corps volant sans pilote. L'unité de détection de gaz émet vers l'avant et en diagonale vers le bas, en regardant depuis la direction de déplacement du corps volant sans pilote, une lumière de détection qui est modulée en fréquence par une fréquence de modulation prédéterminée ayant une fréquence prédéterminée en tant que fréquence centrale. L'unité de détection de gaz, à partir de l'émission de la lumière de détection, reçoit en tant que première lumière la lumière qui a été renvoyée par un emplacement de mesure (un emplacement irradié par la lumière de détection dans un élément tubulaire de transport de gaz), et inspecte une fuite de gaz à l'emplacement de mesure sur la base de la première lumière reçue. L'unité de mesure de distance mesure la distance entre l'unité de détection de gaz et l'emplacement de mesure. L'unité de commande d'altitude commande l'altitude de vol du corps volant sans pilote sur la base de la distance mesurée.
(JA) 無人飛行体には、ガス検知部、測距部及び高度制御部が設置されている。ガス検知部は、所定の周波数を中心周波数として所定の変調周波数で周波数変調した検知光を、無人飛行体の進行方向から見て前方斜め下方に出射する。ガス検知部は、検知光の出射により、測定箇所(ガス輸送用の管状部材のうち、検知光が照射されている箇所)から戻ってきた光を第1の光として受光し、受光した第1の光に基づいて、測定箇所でのガス漏れを検査する。測距部は、ガス検知部と測定箇所の距離を測定する。高度制御部は、測定された距離に基づいて、無人飛行体の飛行高度を制御する。
