Embodiment
The in-situ calibration device of the utility model optical fiber temperature measurement system comprises following structure, hereinafter will be described in detail this with reference to accompanying drawing.
Extremely shown in Figure 2 as Fig. 1, the utility model comprises closed container 1, place detection optical fiber 2 to be calibrated in the closed container 1, semiconductor cooler 3 controlled circuit 5 controls, the actual temperature that temperature measuring equipment 4 is surveyed in the closed container 1, and deliver to control circuit 5, and show by display device 6, also can pass through printing equipment 7 real time prints.
Closed container 1 can be placed 8 to 10 meters detection optical fiber to be calibrated 2, and its internal temperature is by the decision that is provided with of control circuit 5.
Temperature measuring equipment 4 is housed in the closed container 1, and temperature measuring equipment 4 is given control circuit 5 with the Temperature Feedback of the closed container 1 that detects.
The semiconductor cooler 3 that is screwed is housed above the closed container 1, semiconductor cooler 3 under the control of control circuit 5, heat or the closed container 1 that freezes in air, the air in the closed container 1 makes the interior temperature of its temperature and closed container 1 consistent heat transferred detection optical fiber 2.
The in-situ calibration device of this optical fiber temperature measurement system can provide the steady temperature value of 2 above high precision (≤± 0.5 ℃).
The step of the in-situ calibration device of concrete this optical fiber temperature measurement system of operation is as follows:
At first detection optical fiber 2 to be calibrated is put into this device closed container 1, open the power knob among Fig. 3 then, power light is bright, this caliberating device is started working, click the button that is provided with on Fig. 3, this device is in the demarcation temperature set status, by regulating increasing on Fig. 3, subtract button, adjust set temperature value to the steady temperature value of desire demarcation, click the button that is provided with on Fig. 3 once more, this caliberating device is in normal operating conditions, treat that display device shown in Figure 4 reaches after the set temperature value 15 minutes, temperature in the closed container reaches constant, this moment, caliberating device temperature displayed value was exactly the temperature value of detection optical fiber 2 to be calibrated, and the temperature value of this section detection optical fiber 2 that optical fiber temperature measurement system is measured is adjusted into caliberating device temperature displayed value and promptly finishes once and demarcate printable as required this temperature value, according to the actual conditions need of work, can demarcate by said process the multistage detection optical fiber of a plurality of positions of temp measuring system.
This method is one section detection optical fiber that optical fiber temperature measurement system is to be calibrated, places in the device with steady temperature value by control circuit control, thereby detection optical fiber section to be calibrated is in the known standard temperature environment.Temperature value by this section detection optical fiber that optical fiber temperature measurement system is shown is adjusted to this standard temperature value and promptly finishes demarcation to system then.Can demarcate the detection optical fiber many places as required; But this method also field-checking has been used the positional precision and the temperature measurement accuracy of the relevant thermometric section of optical fiber temperature measurement system a period of time of after.
The isoperibol of this caliberating device is made of the closed container of definite shape, certain volume, the temperature of this closed container is made of semiconductor cooler 3, temperature measuring equipment 4, control circuit 5, display device 6 (as shown in Figure 4) and printing equipment 7, can set the temperature of closed container 1 by control circuit 5, and show temperature in the closed container 1 in real time, and can pass through this temperature of printer real time print by display device 6 (charactron).
