An embodiment of the present invention provides an indoor temperature control method based on a laser device, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of an indoor temperature control method based on a laser device according to the present invention.
In this embodiment, the indoor temperature control method based on the laser device includes the following steps:
step S10: a plurality of light pulses emitted by a laser device are acquired, and a reference light pulse is selected from the plurality of light pulses through a reference optical fiber.
It is easy to understand that the execution main body of the embodiment may be an indoor temperature control device based on a laser device having functions of image processing, data processing, network communication, program operation, and the like, or may be other computer devices having similar functions, and the embodiment is not limited thereto.
It will be appreciated that the reference fiber may be a section of fiber made of glass or plastic, which may serve as a light conducting means for transmitting a plurality of light pulses emitted by the laser device, wherein the reference fiber may be a quartz fiber having a length of about 12 meters, or the like.
Further, in order to accurately obtain the reference light pulse, before the step of obtaining the plurality of light pulses emitted by the laser device and selecting the reference light pulse from the plurality of light pulses through the reference optical fiber, the optical fiber length value of the optical fiber is also required to be obtained, and then whether the optical fiber length value meets a preset optical fiber length threshold is judged, and when the optical fiber length threshold does not meet the preset optical fiber length threshold, the optical fiber is intercepted according to the preset optical fiber length threshold, so that the reference optical fiber and the like are obtained.

Assuming that the optical fiber length value of the optical fiber is 150 meters and the preset optical fiber length threshold value is 13 meters, the optical fiber length value is greater than the preset optical fiber length threshold value, the optical fiber needs to be intercepted according to the preset optical fiber length threshold value to obtain an optical fiber of 13 meters, and the obtained optical fiber of 13 meters is used as a reference optical fiber and the like.
It should be noted that, in order to be able to accurately detect the temperature, the reference optical fiber may be placed in a thermostatic water bath device, the temperature may be set according to user definition, and may be a constant temperature of 20 degrees, and the like, wherein the filling liquid in the thermostatic water bath may be an oily liquid, and the present embodiment is not limited.
In a specific implementation, obtaining a plurality of optical pulses emitted by a laser device needs to first perform Wavelength Division Multiplexing (WDM), then input the optical pulses passing through the WDM into a reference optical fiber, and select a reference optical pulse from the plurality of optical pulses through the reference optical fiber, where the WDM may be disposed inside the laser device, and the laser device may be a pulse laser, and the like.
It can be understood that the wavelength division multiplexing is a technology of combining optical carrier signals (carrying various information) with two or more different wavelengths together at a transmitting end through a Multiplexer (also called a Multiplexer), and coupling the optical carrier signals into the same optical fiber of an optical line for transmission; at the receiving end, the optical carriers with various wavelengths are separated by a Demultiplexer (also called a Demultiplexer or Demultiplexer), and then the optical carriers are further processed by an optical receiver to recover the original signal, etc., wherein the wavelength division multiplexing can support 150 optical waves with different wavelengths to be transmitted simultaneously, and the maximum data transmission rate of each optical wave reaches 10Gb/s, etc.
Step S20: and processing the reference light pulse to obtain backward Stokes light and backward anti-Stokes light.

In this embodiment, it is necessary to process the reference light pulse through the optical switch, and then transmit the processed reference light pulse to the sensing fiber, where the light pulse transmits backward scattering light at each point inside the reference fiber and the sensing fiber, and finally, backward stokes light and backward anti-stokes light, etc. can be determined according to the backward scattering light.
An optical switch is an optical device with one or more selectable transmission ports, and functions to physically switch or logically operate optical signals in an optical transmission line or an integrated optical circuit, wherein the optical switch may be a four-channel switch, which controls the on and off of four channels, or a two-channel switch, which controls the on and off of two channels, and so on.
The sensing optical fiber can convert the physical quantity of non-optical signals into optical signals, the optical signals are sensed and transmitted by the optical fiber and finally converted into the measured physical quantity, and the optical fiber is used for measuring the physical quantities such as temperature, pressure, displacement, speed, voltage, current, concentration of molten liquid and the like.

The fiber distribution temperature information may be the absolute temperature at the measurement point, etc.
The step of determining the optical fiber distribution temperature information according to the backward stokes light and the backward anti-stokes light may be to perform wavelength division multiplexing processing on the backward stokes light to obtain a first wavelength signal, perform signal conversion on the first wavelength signal to obtain a first light intensity curve, then perform wavelength division multiplexing processing on the backward anti-stokes light to obtain a second wavelength signal, perform signal conversion on the second wavelength signal to obtain a second light intensity curve, and then determine the optical fiber distribution temperature information and the like according to the first light intensity curve and the second light intensity curve.
In the specific implementation, the backward stokes light and the backward anti-stokes light pass through two output ends of the WDM, then enter an Avalanche Photodiode (APD), are collected and operated by a high-speed collection card, and are converted by an analog-to-digital converter to obtain light intensity curves of the stokes light and the anti-stokes light, namely a first light intensity curve and a second light intensity curve.
Further, in order to obtain accurate optical fiber distribution temperature information, the step of determining the optical fiber distribution temperature information according to the first light intensity curve and the second light intensity curve may be to obtain a first optical power of the first light intensity curve and a second optical power of the second light intensity curve, and then calculate the optical fiber distribution temperature information and the like according to the first optical power and the second optical power and through a preset temperature distribution formula.

wherein h is Planck constant, k is Boltzmann constant, v is Raman frequency shift amount in the optical fiber, t is set temperature, PSIs a first optical power, PAST is the fiber distribution temperature information for the second optical power.
Where V is the propagation velocity of light in the fiber, E is the energy of the pump light pulse, and SASThe scattering coefficient, S, of the backward anti-Stokes Raman scattered light per unit length in the optical fiberSThe scattering coefficient, alpha, of backward Stokes Raman scattered light per unit length in an optical fiber0For the loss factor, alpha, of backscattered light per unit length in an optical fibreASLoss factor of backward anti-Stokes Raman scattered light per unit length in optical fiber, alphasL is the distance from a certain measuring point on the optical fiber to the measuring starting point.
