Description

DTS optical fiber winding pattern forming device {Device of forming winding pattern of DTS optical cable}

The present invention relates to a device for winding a target optical fiber member in a distributed temperature sensing (DTS) system using an optical fiber as a temperature sensor.

More specifically, the present invention relates to an apparatus for winding a target optical fiber member having a length of, for example, about 4 km, at a predetermined interval, but winding the wound portion to have a predetermined pattern that is not twisted with each other on a horizontal plane.

In general, distributed temperature sensing (DTS) is a technology that measures the temperature of a certain area using the scattering phenomenon of an optical fiber, and uses the optical fiber itself as a temperature sensor. That is, the temperature of the optical fiber itself is measured at regular intervals in the section where the optical fiber is installed.

Since optical fiber is a medium that transmits light, DTS can measure temperature relatively accurately without being affected by high voltage current or magnetic field. It has the characteristic of being able to detect quickly.

In general, the DTS system measures the temperature using a so-called Raman scattering phenomenon, which is a type of backscattered light. That is, after irradiating a laser to the optical fiber, the temperature is inferred by analyzing the backscattered light that loses or gains energy among the light scattered from the laser.

[FIG. 1] is an exemplary diagram showing the backscattered light characteristics of the DTS system. Referring to FIG. 1, the temperature of the optical fiber can be calculated at regular intervals by using the ratio between the temperature-insensitive stroke signal and the temperature-sensitive anti-stroke signal through Raman scattering. can

[Fig. 2] is an exemplary diagram showing the response characteristics of the backscattered light of the DTS system. Referring to [Fig. 2], the temperature value can be calculated corresponding to the signal magnitude of the backscattered light, and depending on the arrival time of the reflected backscattered light after the laser is irradiated to the optical fiber (eg, 10ns, 20ns, 30ns, 40ns) The location of the calculated temperature (eg 1m, 2m, 3m, 4m) is known (1m = 10ns). In this case, the propagation speed and refractive index of light in the optical fiber are used to calculate the position.

3 is an exemplary diagram schematically illustrating the internal configuration of a general DTS system. Referring to FIG. 3 , the signal generating member 40 generates a trigger signal (eg, a 25 kHz square wave signal) and provides it to the laser output member 50 . In accordance with this trigger signal (eg, a 25 kHz square wave signal), the laser output member 50 irradiates a laser, and the laser irradiates the laser to the target optical fiber member 10 so as to pass through the reference optical fiber member 60 .

Back-scattered light with respect to the laser is generated from the target optical fiber member 10 , and the back-scattered light reaches the light receiving member 20 via the reference optical fiber member 60 . The light receiving member 20 acquires an optical signal (stroke signal) of a stroke wavelength of the Raman band and an optical signal (anti-stroke signal) of an anti-stroke wavelength from the backscattered light.

Meanwhile, the signal generating member 40 not only generates a trigger signal (eg, a 25 kHz square wave signal) and provides it to the laser output member 50 , but also generates a clock signal (eg, a 200 MHz square wave signal) to the AD converter member (30) is provided. The AD converter member 30 samples the stroke signal and the anti-stroke signal provided from the light receiving member 20 by a clock signal (eg, 200 MHz) to generate a series of digital values (backscattered light data). . The signal processing member 70 may obtain the temperature at regular intervals along the optical fiber by analyzing the backscattered light data generated by the AD converter member 30 .

Referring to FIG. 2 , a laser pulse is generated at a cycle of 1/25 kHz = 40 usec according to the trigger signal and transmitted to the target optical fiber member 10 . When the light receiving member 20 receives the backscattered light generated by the laser pulse and provides it to the AD converter member 30 , the AD converter member 30 samples at a 10 nsec period according to a 100 MHz clock signal to receive a plurality of A digital value, ie, a sequence of digital values, is provided to the signal processing member 70 . This digital value sequence is a plurality of digital values obtained by the AD converter member 30 A/D converting the stroke signal and the anti-stroke signal according to the clock signal at a period of 10 nsec. The signal processing member 70 calculates a temperature value at intervals of 1 m from the digital value sequence.

Such a DTS system is being used for fire monitoring of power facilities and power lines, battery fire monitoring of ESS systems, and tunnel fire monitoring.

On the other hand, it is important to make the temperature sensing interval small in the DTS system. In general, the temperature sensing interval is about 50 cm to 1 m.

However, while the target optical fiber member 10 winds the target portion of the temperature measurement object, a phenomenon in which the target optical fiber member 10 is twisted occurs, so that the target optical fiber member 10 is accurately aligned with the temperature measurement object in the corresponding area. There is a problem in that the reliability of temperature sensing decreases due to the non-contact.
