1. Что такое оптоволоконное зондирование

Fiber optic sensing is a measurement approach that uses light traveling in optical fibers to infer температура, напряжение, вибрация, and acoustic energy. В отличие от электрических датчиков, optical fibers are диэлектрик и невосприимчив к электромагнитным помехам, allowing measurement over tens of kilometers with high accuracy and safety. На практике, a single cable can act as a continuous sensor or host multiple discrete sensing points, feeding data to an interrogator that converts optical effects into engineering values.

For Malaysian operators—utilities, масло & газ, транспорт, and data centers—fiber optic sensing delivers robust performance in high-humidity rooms, outdoor substations, coastal corridors, and lightning-prone zones where conventional sensors struggle.

2. How Fiber Optic Sensors Work

Optical fibers guide light through a glass core. When temperature or strain changes, the optical properties of the fiber shift slightly. Interrogators detect these minute changes and translate them into physical measurements in real time.

• Точечное зондирование (например, ВБР): An encoded grating reflects a narrow wavelength; any thermal or strain change shifts that wavelength.
• Распределенное зондирование (например, ДТС/ДАС): The entire fiber is the sensor. Backscattered signals (Рамановский, Бриллюэн, или Рэлей) are analyzed along the fiber length to produce a continuous temperature or acoustic/vibration profile.

Because the sensor is glass and the signal is light, the system is electrically safe, lightning-tolerant, and compatible with HV environments—ideal for substations and rail traction power where EMI is significant.

3. Types of Fiber Optic Sensing (ВБР, ДТС, ТО)

3.1 Волоконная решетка Брэгга (ВБР)

Датчики ВБР are discrete points written into the fiber that reflect specific wavelengths. When the grating experiences temperature or strain, the reflected wavelength shifts predictably. FBGs are compact, мультиплексируемый, and precise, делая их пригодными для мониторинг горячих точек трансформатора, structural strain on bridges, and equipment condition tracking. In power applications, FBG probes are commonly packaged for safe placement near windings or on busbars to track thermal behavior with fast response.

3.2 Распределенное измерение температуры (ДТС)

ДТС measures temperature continuously along the fiber using Raman or Brillouin backscatter. One fiber can monitor kilometers of assets with meter-level resolution. Typical Malaysian use cases include underground cable corridors, масло & газопроводы, tunnel fire detection, and data center underfloor temperature mapping. DTS excels where you need continuous coverage rather than point readings.

3.3 Распределенное акустическое зондирование (ТО)

ТО converts standard fiber into a continuous acoustic/vibration sensor by analyzing coherent Rayleigh backscatter. It detects footsteps, third-rail tampers, pipeline encroachments, or transformer acoustic patterns. В Малайзии, DAS is valuable for railway right-of-way security, perimeter monitoring at critical facilities, and real-time intrusion or leak detection.

4. Advantages in Malaysian Conditions

• иммунитет к электромагнитным помехам: Reliable near HV switchgear, тяговая мощность, and large drives.
• Long-reach coverage: Monitor assets over tens of kilometers with one interrogator.
• Tropical robustness: Glass sensors are corrosion-free and stable in high humidity.
• Безопасность: Dielectric sensors eliminate conductive paths in high-voltage or hazardous zones.
• Low maintenance: Minimal recalibration; no drift from electrical interference.
• Multi-parameter capability: Температура, напряжение, and acoustic events in one architecture.

5. Applications of Fiber Optic Sensing in Malaysia

Malaysia’s infrastructure spans coastal corridors, dense cities, industrial estates, and rainforest terrain. Fiber optic sensing delivers high resilience and actionable visibility across these varied environments.

5.1 Power Grid and Transformer Monitoring

Utilities and large industrial campuses deploy FBG and distributed sensing to improve reliability and safety. Для силовые трансформаторы in substations and traction power systems, мы рекомендуем флуоресцентный оптоволоконный датчик температуры or FBG-based hot-spot sensing for температура обмотки и сердечника due to immunity to electromagnetic fields and fast response under load swings. Optical probes placed at critical locations provide precise thermal insights, while DAS can listen for acoustic anomalies associated with mechanical looseness or partial discharge signatures.

• Track hot-spot temperature and correlate with load to prevent insulation stress.
• Combine transformer vibration and acoustic patterns for early anomaly detection.
• Extend coverage to cable tunnels and switch rooms using DTS for fire and overheating detection.

Data is integrated into SCADA or condition-monitoring dashboards via Modbus TCP, МЭК 61850 шлюзы, or OPC UA—supporting Malaysian utility workflows and compliance audits.

5.2 Масло & Gas Pipelines and Terminals

DTS and DAS are widely used to monitor long pipelines for утечки, температурные отклонения, вмешательство третьей стороны, and intrusion. Coastal terminals benefit from corrosion-proof, intrinsically safe sensing with continuous coverage. Operators receive event localization in real time to shorten response windows and reduce environmental risk.

5.3 Railways and Smart Transportation

DAS along track corridors detects trespass, cable theft, rockfalls, and abnormal vibration. In metro tunnels, DTS enhances fire detection and ventilation control. Fiber sensors also monitor traction substations and third-rail segments where EMI challenges conventional electrical sensors.

5.4 Civil Infrastructure and Bridges

FBG networks measure напряжение, tilt, and thermal expansion on bridges, viaducts, and high-rise structures. Engineers can identify early fatigue or settlement and plan maintenance without disrupting traffic. DTS adds continuous обнаружение пожара in tunnels and enclosed spaces.

5.5 Water Resource, Flood, and Landslide Monitoring

Distributed sensing supports levee seepage detection, dam surveillance, slope movement alerts, and floodplain temperature mapping. The long reach and passive nature of the fiber cable make it ideal for remote or lightning-prone sites during monsoon seasons.

5.6 Data Centers and Industrial Automation

DTS monitors underfloor hot zones, overhead trays, and battery rooms, while FBG probes provide precise temperature at racks or busways. Optical sensing improves resilience for facilities facing rapid capacity growth in Greater Kuala Lumpur, Penang, Johor, and Sarawak.
