Pipeline transportation is one of the international transportation methods for goods, which uses underground pipelines to transport crude oil, gaaska dabiiciga ah, refined oil, slurry, coal slurry and other media to their destination. Compared to other transportation methods, it has the advantages of large capacity, unrestricted by climate and other ground factors, continuous operation, iyo qiimo jaban, and has become an important way for oil and gas transportation. Due to the fact that long-distance oil and gas pipelines are mostly distributed in deserted areas such as the wilderness, they are susceptible to external human damage (such as drilling holes to steal oil, iwm.) and sudden natural disasters (such as earthquakes, landslides, iwm.), resulting in pipeline fractures and oil and gas leakage accidents; Also, due to the shallow burial of pipelines, they are often threatened by various construction activities when passing through residential areas, as incidents of damage and pipeline excavation caused by barbaric construction often occur. Oil and gas pipelines have the characteristics of high temperature, high pressure, flammability, and explosiveness. Once a leak occurs, it not only shuts down the pipeline, but also seriously pollutes the environment, posing a serious threat to the lives and property of local people. If it causes the combustion and explosion of leaked oil and gas, the consequences are unimaginable. Gudbinta dhuumaha waxay leedahay faa'iidooyin badan sida dhaqaalaha, hufnaan, badbaadada, iyo xasiloonida, waxaana lagu mariyaa daabulka dareeraha sida saliidda, gaaska dabiiciga ah, iyo biyaha. Iyadoo horumarka joogtada ah ee dhaqaalaha bulshada iyo farsamada, Tuubooyinka dhigista ayaa si weyn loo isticmaalay. Nidaamyada dhuumaha ayaa si weyn looga isticmaalaa goobaha warshadaha sida batroolka, biraha, biyaha magaalada, iyo gaaska dabiiciga ah. Arrinta ilaalinta badbaadada dhuumaha ayaa sidoo kale si isa soo taraysa uga muuqata dadka hortooda. Dhuumaha waxaa lagu aasay dhulka hoostiisa sanadka oo dhan waxayna u nugul yihiin daxalka, dhaawac daal, ama daadinta, Taas oo aan kaliya keenin khasaare dhaqaale oo baaxad leh balse sidoo kale wasakhaysa deegaanka. Sidaa darteed, studying effective pipeline leak detection techniques is extremely important for ensuring the safe transportation of pipelines.

Advantages of Distributed Fiber Optic Pipeline Temperature Measurement System

Cabbiraadda heerkulka agagaarka dhuumaha si loo go'aamiyo in dillaacu dhacay iyo in kale waa hab caadi ahaan la isticmaalo. Si kastaba ha ahaatee, cabbirka heerkulka dhaqameedku waa habka cabbiraadda hal dhibic, iyo la socodka xaaladda dhuumaha waxay u baahan tahay in la geeyo tiro badan oo ah dareemayaasha heerkulka, taasoo dhib u keenta dhismaha iyo dayactirka. Nidaamka cabbiraadda heerkulka qaybsan ee fiber optic waa nidaam dareen ah oo la sameeyay sannadihii ugu dambeeyay ee cabbiraadda waqtiga-dhabta ah ee qaybinta heerkulka goobta.. Fiber optic waa dhexdhexaad ah gudbin iyo dhexdhexaad ah labadaba, iyo saamaynta heerkulka dib u firdhinta Raman waxaa loo isticmaali karaa in lagu cabbiro heerkulka fiber-waqtiga dhabta ah; Isticmaalka tignoolajiyada milicsiga-waqtiga-Domain-ka indhaha ayaa si sax ah u heli kara dhibcaha cabbirka. Nidaamkani wuxuu cabbiri karaa qaybinta heerkulka masaafada dheer gudaha waqti gaaban. Sababtoo ah mugga yar ee fiber-ka indhaha, Habka cabbirku ma saameyn doono qaybinta goobta heerkulka asalka ah. Isla markaana, waxa kale oo ay leedahay sifooyinka ka hortagga ololka, ka hortagga qaraxa, iska caabin daxalka, iyo caabbinta faragelinta korantada. Sidaa darteed, Nidaamka cabbiraadda heerkulka qaybsan fiber indhaha waxay leedahay rajooyin codsi oo wanaagsan oo ku saabsan tignoolajiyada la socodka qulqulka dhuumaha.
Nidaamka cabbiraadda heerkulka fibre optic-ga ee ku salaysan tignoolajiyada kala firdhisanaanta Raman ayaa hadda si weyn loogu isticmaalaa nidaamka la socodka daadinta dhuumaha. The oil and gas pipeline leakage monitoring system mainly consists of a distributed fiber optic temperature measurement host and corresponding temperature measurement optical cables, which continuously and linearly monitor the temperature of the pipeline in real-time, thereby monitoring the pipeline leakage situation. The entire monitoring system is connected to the pipeline SCADA system through its temperature measurement control host communication interface or dry contact relay terminals, and is responsible for providing alarm information and operation and fault signals to it.
When a leak occurs in a certain part of the pipeline, the system monitors a sharp change in temperature and quickly identifies the risk; By monitoring the gradual temperature changes of a certain section of pipeline over a period of time, it can be determined that there is an abnormal risk of leakage in the pipeline. The system can accurately locate the location of faults, repair pipeline faults, shorten time, and improve economic benefits for customers.

The oil pipeline fiber optic leak detection online safety monitoring system developed by FJINNO uses the IFDTS-SO distributed fiber optic temperature measurement system, which is installed in a cabinet and can be simultaneously connected to the upper service computer for comprehensive monitoring of the oil pipeline status. Combined with software display, sound and light, network, SMS and other alarm methods, it provides reliable guarantees for the safe operation of oil pipelines. The online monitoring system for oil pipeline fiber optic leakage detection consists of SRDTS-SO distributed fiber optic temperature measurement system, signal transmission unit, and signal processing unit. The signal transmission unit is one core of communication fiber laid along the oil pipeline.

Function of Distributed Fiber Optic Sensing System for Leakage Detection of Oil Pipeline Fiber Optic

1. Oil pipeline leakage detection: By implementing temperature monitoring around optical cables, the purpose of oil pipeline leakage detection is achieved;

2. Abnormal alarm: When the detected temperature exceeds the set range, an alarm message will be prompted and operation suggestions will be given;

3. Differential temperature alarm: The alarm parameters support manual setting, output relay alarm signals and alarm positioning information, and achieve differential temperature alarm;

4. Alarm zone setting: The system can program the length and alarm points of the alarm area as a whole, and can be flexibly adjusted according to the on-site situation;

5. Data analysis: storing, querying, and analyzing historical data;

6. Remote access: The system can connect to industrial Ethernet and transmit data to various levels of management departments to achieve remote access.
