Technical field
The utility model relates to distributed optical fiber temperature sensor technology, particularly a kind of distributed fiber temperature sensing network.
Background technology
Distributed optical fiber temperature sensor (Distributed Temperature Sensor; Abbreviation DTS) ultimate principle is: the end at sensor fibre injects laser pulse; Energy exchange takes place in thermal vibration and photon interaction owing to the fibre core molecule when laser pulse is propagated in optical fiber, has produced Raman scattering.Wherein, Raman's anti-Stokes light is very sensitive to temperature, because the velocity of propagation of photon in optical fiber be certain, and the time delay of the Raman's anti-Stokes light through detecting back-propagating; The accurate temperature information in the positioning optical waveguides just, thus realized distributed fiber temperature sensing.
Compare with traditional inductance inductive transducer, DTS has the advantage of many brilliances: as sensing media, one-shot measurement just can obtain thousands of somes temperature informations along fiber distribution with optical fiber itself, has realized the measurement of continuous distribution formula, has reduced uncertainty of measurement; Far measuring distance, Measuring Time is short, is fit to remote real-time monitoring; Highly sensitive, measuring accuracy is high, and rate of false alarm, rate of failing to report are low; Corrosion-resistant, water-fast, fire-resistant, electromagnetic interference (EMI) is immune, reliability is high, maintenance cost is low.Therefore, distributed optical fiber temperature sensor has all obtained application more and more widely in a lot of fields.
Its weak point is: because the coverage of separate unit DTS main frame is that limited (for example certain DTS main frame has 2 kilometers of 4 monitoring channels, each channel monitorings; Maximum can only be monitored 8 kilometers line type temperatures and distributed), in practical application, often can not satisfy the demands (for example subway tunnel, raceway groove cable thermometric need tens kilometers easily).
