Zusammenfassung: | Disclosed is an overhead transmission line communication system using distributed acoustic sensing. According to the system, a transmitter converts a sensing signal received from a plurality of sensors installed to sense a status of an overhead transmission line from the overhead transmission line and an optical fiber composite overhead line (OPGW) connected between transmission towers into a vibration signal of the corresponding frequency and inject the sensing signal into optical cable in OPGW. A receiver measures the vibration signal transmitted through the OPGW optical cable through distributed acoustic sensing (DAS), converts the vibration signal into a corresponding digital signal, and transmits the digital signal to the server which monitors the overhead transmission line.
분포형 음향 센싱을 이용한 가공송전선로 통신 시스템이 개시된다. 이 시스템에서, 송신부는 송전탑들 사이에 연결되어 있는 가공송전선로와 광섬유 복합 가공지선(OPGW) 중 가공송전선로의 상태를 센싱하기 위해 설치된 복수의 센서로부터 수신되는 센싱 신호를 대응되는 주파수의 진동 신호로 변환하여 OPGW 내의 광케이블에 주입한다. 수신부는 분포형 음파 센싱(DAS)을 통해 OPGW의 광케이블을 통해 송신되는 진동 신호를 측정하여 대응되는 디지털 신호로 변환하여 가공송전선로에 대한 감시를 수행하는 서버로 전달한다. |
