Application of Vibration Fiber Optic Perimeter Alarm System in Pipeline Detection-INNO

There are various pipelines buried in the city, including transporting water, ガス, そして油. Once a leak occurs, it will inevitably cause serious ecological damage and huge economic and property losses. 現在のところ, effective and inexpensive safety monitoring methods for oil and gas pipelines before leakage are still a global challenge. 長い間, a large amount of research has been conducted both domestically and internationally on the use of stress wave method and negative pressure method for leak detection. しかし, due to the insufficient processing of detection signals by various leak detection methods, their applications are not ideal. When a leak occurs, the detection range is too large, time-consuming and laborious. さらに, negative pressure leak detection method needs to damage the pipeline structure and extend the detection head into the pipeline, which is very inconvenient.

パイプラインは、天然ガスなどの重要なシステムに不可欠な物質輸送施設です, 油, 都市暖房, そしてガス. 国民経済の発展とエネルギーと物質の輸送にとって非常に重要です. 同時に, パイプライン施設には巨額の投資があり、そのほとんどは溝の中に設置されるか、地面の下に埋められます。. 宇宙ではある程度の隠蔽性を持っています. 人為的または自然的理由により損傷した場合, タイムリーに検出するのは困難です. 可燃性および爆発性物質の漏洩は、安全上に重大な危険をもたらします。. 火災・爆発事故を起こした場合, それは多大な経済的損失をもたらすだろう, そして重大な死傷者や社会的混乱を引き起こすことさえあります.

の distributed fiber optic vibration sensing system is a very cost-effective event sensing system, which has irreplaceable advantages in long-distance applications exceeding 10km. いつもの, in applications where 分散型光ファイバー vibration sensing and video surveillance systems are linked, these two systems work independently and require independent power supply systems and independent information transmission channels. いつもの, in video surveillance systems, the cameras at each monitoring point require local power supply. When the transmission distance exceeds 10km, the power transmission system becomes a very complex and expensive system. In the Gobi, desert, sparsely populated mountains, and swamps, local power supply is basically an impossible condition to achieve.

の vibration fiber optic cable detection alarm system is a powerful perimeter alarm system. Ordinary communication optical cables are used as sensing units, and communication optical cables are used for communication. The front-end detectors are detected using a C/S (client/server) network form. The alarm center can be divided into a multi-level all fiber structure, with unlimited access to detectors. The alarm center can be interconnected through the Internet or local area network. Transfer the detected intrusion and destruction signals to the alarm center server, analyze and process the signals through alarm software, ultimately determine the alarm information, and display the alarm location on the electronic map. The alarm center is connected to a network type data collector through a local area network. Each alarm center can connect up to 128 network type data collectors. Each collector can deploy two defense zones and can set up 256 defense zones, with an effective length detection of 1000m for each defense zone. Each collector has an independent IP address, which can directly control or adjust the working status and internal parameters of the collector in the control room.
