Introduction to Distributed Fiber Optic Acoustic Sensing System
A measurement system developed based on distributed fiber optic sensing technology. It is a comprehensive new distributed fiber optic sensing technology system that integrates multiple disciplines such as optics, electronics, mechanics, and digital signal processing, based on the Rayleigh scattering effect generated by optical signals during fiber optic propagation and the principle of optical time domain reflectometry (ওটিডিআর) টেকনোলজি. এই ব্যবস্থায়, optical fibers are both devices for transmitting optical signals and sensing external information. সুতরাং, they can continuously and quickly measure external acoustic and vibration information along the fiber optic cable.

Distributed fiber optic temperature sensor for substations
The fiber optic temperature measurement system used for substation temperature monitoring can accurately and timely locate temperature anomalies on a single fiber optic cable through distributed fiber optic temperature testing based on Raman scattering temperature measurement technology; একই সঙ্গে, the system is equipped with multi-level temperature alarm values and temperature rise rate alarms, displaying temperature distribution curves in real time, and providing early warning before a fire occurs. This solves the problem that existing temperature measurement systems can only passively set a temperature threshold, which is prone to misjudgment and cannot accurately locate the location of the accident point. Distributed fiber temperature testing based on Raman scattering temperature measurement technology can accurately and timely locate temperature anomalies on a single fiber; একই সঙ্গে, the system is equipped with multi-level constant temperature alarm values and temperature rise rate alarms, displaying temperature distribution curves in real time, and providing early warning before a fire occurs, greatly reducing the probability of substation fires.
Oil pipeline leakage temperature vibration host
বর্তমানে, oil and gas pipelines are an important component of petroleum and natural gas engineering. Due to corrosion, weld defects, external vibrations, and even theft and damage, pipeline leaks, damage to anti-corrosion coatings, and leaks and corrosion at pipeline connections such as flanges, threaded buckles, and packing boxes have become increasingly severe. Pipeline leakage not only causes obstruction of transportation, but also pollutes the environment and even triggers accidents such as explosions and fires, requiring a significant amount of manpower and resources for monitoring, maintenance, and management. So early prevention, timely warning, and location of pipeline leaks have very important practical significance.
একই সঙ্গে, oil and gas need to be heated during transportation to promote flow. The heating device heats the oil to a certain temperature and then transports it in pipelines. তবে, excessive heating can cause resource waste and increase the cost of oil and gas transportation. How to set heating reasonably is of great significance for energy consumption control in oil and gas engineering. The temperature of oil in pipelines will decrease, forming a temperature gradient that decreases with transportation distance. The real-time and distributed monitoring values of this temperature can serve as an important basis for heating feedback control, which plays an important role in reasonable temperature control and reducing transportation energy consumption.
The comprehensive monitoring system for oil and gas pipelines is equipped with optical cables inside the pipelines, যা ফাইবার অপটিক মনিটরিং হোস্টের সাথে সংযুক্ত. অপটিক্যাল কেবলগুলি রিয়েল টাইমে তেল ও গ্যাস পাইপলাইনের কম্পন সংকেতগুলি অনুভব করে এবং বিভিন্ন অবস্থানে তেল ও গ্যাস পাইপলাইনগুলির ফুটো অবস্থা সনাক্ত করতে ফাইবার অপটিক মনিটরিং হোস্টে প্রেরণ করে. তাদের মধ্যে অন্যতম, কম্পন সংকেত প্রধানত বহিরাগত কম্পন এবং এমনকি চুরি এবং ক্ষতি প্রতিফলিত করতে পারে.
Distributed fiber optic monitoring of water pipeline temperature
Once invaded by malicious excavation, drilling, or geological disasters causing pipeline rupture and damage, it will be destroyed and even lead to environmental pollution and economic losses. In order to maintain safety along the pipeline and prevent human or environmental damage, it is necessary to conduct real-time online monitoring of the working status of water pipes and provide timely and accurate advance alarms for threatening intrusion events. সুতরাং, pipeline safety monitoring technology plays an important role in maintaining pipeline transportation and has social and economic significance.
Distributed fiber optic temperature measurement system is a technology used for real-time measurement of temperature spatial distribution, which can be widely applied to temperature detection and fire warning in coal mines, সুড়ঙ্গ, large buildings, transmission cables, তারের ট্রে, and other areas. The distributed fiber optic temperature measurement system mainly uses the principle of spontaneous Raman scattering inside the fiber optic to measure temperature, and uses the principle of optical time domain reflection to locate and realize the temperature sensing system for measuring the temperature field.
DAS distributed fiber optic acoustic vibration monitoring
The distributed fiber optic sensing system based on the principle of phase sensitive photosensitive time-domain reflection (Φ – ওটিডিআর) has the advantages of simple structure, long detection distance, ability to locate multiple disturbances simultaneously, high resolution, and accurate positioning accuracy. It can be applied in water supply pipeline leak monitoring to detect and locate the leak location in real time without causing any damage or affecting the normal operation of the pipeline. Distributed acoustic sensing (DAS) is based on the Φ – OTDR technology, which detects the phase signal of backscattered light in the sensing fiber to achieve the detection of distributed sound or vibration signals. It not only provides sound or vibration event intensity information using phase and amplitude, but also uses linear quantitative measurement values to obtain sound time phase and frequency information.
