Sensori di temperatura a fibra ottica INNO ,sistemi di monitoraggio della temperatura.
Il sistema di monitoraggio online della temperatura distribuito in fibra ottica è attualmente una tecnologia avanzata per il monitoraggio non elettrico degli oleodotti. Conduce il monitoraggio distribuito online della temperatura degli oleodotti ed è collegato in parallelo da varie apparecchiature di monitoraggio degli oleodotti alla rete locale del sistema completo di monitoraggio online degli oleodotti. I dati di allarme e le informazioni sulla temperatura vengono caricati sul server centrale tramite segnali di rete.
Nella fase iniziale di danni e perdite dell'oleodotto, è possibile determinare, rilevare e segnalare la posizione specifica, variazioni di temperatura, e altri dati informativi sui punti di allarme per le perdite degli oleodotti per la prima volta, fornire mezzi affidabili e solidi di acquisizione di informazioni per i dipartimenti di utilizzo e gestione degli oleodotti per individuare e analizzare tempestivamente possibili eventi di infrazione e danni alla linea, e fornire efficaci garanzie di sicurezza per il funzionamento sicuro del sistema di oleodotti.
Il gas naturale nei gasdotti è altamente compresso. Quando si verifica una perdita, il gas naturale all'interno del gasdotto fuoriesce dalla rottura e poi si espande rapidamente. Durante questo processo, il gas naturale assorbirà una grande quantità di calore circostante, portando ad un forte calo della temperatura vicino al sito di rottura.
IL fibra ottica distribuita Il sistema di monitoraggio delle perdite della pipeline presenta i seguenti vantaggi tecnici:
Solidità
The system has a very high temperature measurement and positioning speed. In order to improve measurement time, the advantage of high-speed weak signal processing technology is adopted, with a minimum single measurement time of 1 second and fast response speed.
Distribution characteristics
The distributed fiber optic pipeline leakage monitoring system can provide continuous dynamic monitoring of temperature changes at points every 0.5 meters within a range of more than ten kilometers, and can set temperature alarm values at any level.
Progressività
The distributed fiber optic pipeline leakage monitoring system is currently the most advanced distributed temperature measurement product with the highest performance indicators, strongest functionality, massima affidabilità, and most advanced technology in the world. High performance components are selected for key components, and the core algorithm has been rigorously tested.
precisione
The temperature resolution of the system reaches 0.5 ℃, with a temperature accuracy of 1 ℃ and a spatial resolution of 0.5m.
flessibilità
The system adopts real-time online monitoring mode; The time for uploading alarm signals from any point within the monitoring range to the fire alarm controller shall not exceed 30 secondi.
The monitoring system provides a continuous dynamic monitoring signal, and the system can set multi-level temperature point alarms. The system supports multi-level alarms, come l'allarme iniziale alle 30 ℃, early alarm at 40 ℃, e le misure adottate a 50 ℃. The temperature parameters of the alarm points can be set according to different environments; There are multiple alarm methods with differential temperature control, and the alarm parameters can be set in zones according to customer needs, with flexible alarm methods.
compatibilità
The system host adopts an open communication protocol and provides a communication interface to connect with the workstation. The disaster prevention alarm workstation in the central control room displays all information such as temperature curve, alarm position, and alarm temperature in Chinese graphic and textual format.
The system can be connected to other control devices such as PC and fire alarm systems through output forms such as RS232, RS485, relè incorporati, RJ45, or other industrial protocols, to perform sound and light alarms, and the signal output is accurate and complete.
Sicurezza
The distributed fiber optic pipeline leakage monitoring system has a safety record function, which can store historical data within one year and can be effectively audited.
Single end operation, remote diagnosis, and the lowest level of system remote diagnosis can be provided by specialized engineers through the local area network; If the optical fiber is damaged, the DTS system can immediately locate the damaged point and fuse it through the fiber fusion splicer without stopping the measurement, which is very important for effective online monitoring.
The intrinsic safety of the detection optical cable is achieved by using optical signals, which will not cause mutual electromagnetic interference with the power cable.
User software
Provide a user-friendly and easy-to-use distributed fiber optic temperature monitoring application software. Il software comprende principalmente moduli funzionali come il monitoraggio della temperatura, allarme antincendio, e visualizzazione visiva.
Visualizzazione della curva della temperatura
Il sistema può visualizzare la curva di distribuzione della temperatura in tempo reale dell'intero cavo ottico, e quando c'è una temperatura anomala in una determinata posizione, la curva può mostrare se la temperatura in quella posizione aumenta o diminuisce.
Distributed Fiber Optic Long Oil and Gas Pipeline Safety Monitoring System
Long distance oil and gas pipelines are mostly distributed in deserted areas such as the wilderness, and are susceptible to external human damage and sudden natural disasters (such as earthquakes, landslides, ecc.), resulting in pipeline rupture and oil and gas leakage accidents. Due to the characteristics of high temperature, alta pressione, infiammabilità, and explosiveness of oil and gas pipelines, 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 even more unimaginable.
Tecnologia di rilevamento in fibra ottica, with its ability to achieve long-distance passive distributed sensing, is very suitable for the safety monitoring market demand of long oil and gas pipelines. Its on-site non electric detection, wide coverage range, and high positioning accuracy are currently recognized as the best technical solution.
Our company has launched a distributed fiber optic oil and gas pipeline safety warning system to meet the demand for safety monitoring and early warning applications in long-distance oil and gas pipelines, providing a solution to ensure the safe operation of oil and gas pipelines. Multi parameter comprehensive perception of potential risks along the pipeline, using deep learning algorithms to analyze and identify threat events along the pipeline, making the safe operation management of oil and gas pipelines more intelligent, orderly, in tempo reale, and efficient.
