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

There are various pipelines buried in the city, including transporting water, 가스, 그리고 기름. Once a leak occurs, it will inevitably cause serious ecological damage and huge economic and property losses. 현재, effective and inexpensive safety monitoring methods for oil and gas pipelines before leakage are still a global challenge. For a long time, 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. 하지만, 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. 게다가, negative pressure leak detection method needs to damage the pipeline structure and extend the detection head into the pipeline, which is very inconvenient.

Pipelines are essential material transportation facilities for important systems such as natural gas, 기름, urban heating, 그리고 가스. It is of great significance for the development of the national economy and the transportation of energy and materials. 동시에, pipeline facilities have a huge investment and are mostly located in trenches or buried below the ground. 그들은 공간에서 어느 정도 은폐성을 가지고 있습니다.. 인간 또는 천재지변에 의하여 훼손된 경우, 적시에 탐지하기가 어렵습니다.. 가연성, 폭발성 물질이 누출되면 안전에 큰 위험이 발생합니다.. 화재나 폭발사고가 발생하는 경우, 막대한 경제적 손실을 가져올 것이다, 심각한 인명피해와 사회혼란을 초래하기도 합니다..

그만큼 distributed fiber optic vibration sensing system is a very cost-effective event sensing system, which has irreplaceable advantages in long-distance applications exceeding 10km. 대개, in applications where 분산 광섬유 vibration sensing and video surveillance systems are linked, these two systems work independently and require independent power supply systems and independent information transmission channels. 대개, 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.

그만큼 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.
