The optical fiber for temperature calibration is winded on the red copper constant temperature box circular shaft; a thermistor of the temperature sensor detects the temperature of a red copper mould; the semiconductor refrigerator is placed at the bottom of the red copper mould for heating and refrigerating control; and a radiator is placed at the bottom of the refrigerator for radiation.
Description
Technical field:
The utility model is about a kind of fiber optic temperature calibration constant temperature box, is applicable to the power cable optical fiber temperature measurement system.
Background technology:
In temperature-measuring system of distributed fibers, the measurement of fiber optic temperature is to record to the Raman scattering temperature effect according to the back of the optical time domain reflection principle of optical fiber and optical fiber, in order to record the temperature of optical fiber each point, need one section optical fiber and be in the canonical reference that the stationary temperature state calculates as optical-fiber temperature measuring.The stability of constant temperature fiber optic temperature and precision are high more, and the measurement of fiber optic temperature is just accurate more, handle so need a fiber optic temperature calibration constant temperature box that optical fiber is carried out constant temperature.
At present, optical fiber is carried out constant temperature generally adopts electrical heating type water logging bubble to handle, one section optical fiber is immersed in the water, the temperature sensor water temperature detection, the temperature of electrical heating control water, this mode electrical heating power is bigger, because adopt liquid constant temperature, configuration aspects more complicated, working service are got up also cumbersome.
The utility model content:
The utility model purpose is to provide a kind of fiber optic temperature calibration constant temperature box, and it can reduce the volume of existing fiber attemperating unit, improves temperature control method.
The technical solution of the utility model is: a kind of fiber optic temperature calibration constant temperature box is characterized in that: comprise constant temperature lid plate, red copper constant temperature box circular shaft, temperature sensor, semiconductor cooler and heating radiator; Its connected mode is, on the red copper constant temperature box circular shaft temperature sensor is installed, temperature sensor is installed in red copper constant temperature box circular shaft surface, Temperature Scaling section optical fiber is wound on the red copper constant temperature box circular shaft, semiconductor cooler places red copper constant temperature box bottom, and heating radiator places the another side of semiconductor cooler.
The beneficial effects of the utility model are: fiber optic temperature calibration constant temperature box adopts the red copper material, and it is constant evenly effectively to guarantee to calibrate fiber optic temperature, and volume is little, simple in structure, easy care.
Description of drawings:
Fig. 1 is the one-piece construction figure of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The explanation of mark among Fig. 1: 1-constant temperature lid plate, 2-red copper constant temperature box circular shaft, 3-temperature sensor, 4-semiconductor cooler, 5-heating radiator.
As shown in Figure 1, the utility model embodiment fiber optic temperature calibration constant temperature box is made up of constant temperature lid plate 1, red copper constant temperature box circular shaft 2, temperature sensor 3, semiconductor cooler 4 and heating radiator 5.Temperature sensor peace 3 is contained in red copper constant temperature box circular shaft 2 surfaces, and Temperature Scaling section optical fiber is wound on the red copper constant temperature box circular shaft 2, and semiconductor cooler 4 places red copper constant temperature box bottom, and heating radiator 5 places the another side of semiconductor cooler 4.
Temperature sensor 3 is surveyed red copper constant temperature box temperature, and the external control card is done the pid algorithm processing according to red copper temperature value and set temperature value, by 4 work of driving circuit control semiconductor cooler; Semiconductor cooler 4 places constant temperature box below, and by hot transfer principle control constant temperature box temperature, the control temperature value is by the output of pid algorithm control refrigerator, make the constant temperature box temperature constantly and set temperature value draw close; The one side of simultaneously generating heat during semiconductor cooler work refrigeration, and can exchange, thereby can carry out the two-way temperature control of heating and cooling to the constant temperature box, heating radiator 5 places the refrigerator another side to play the energy emission effect.
