Description
Technical field
The present invention relates to a kind of calibrating installation, a kind of meteorology optical fiber sensor temperature being easily installed and overhauling
Calibrating installation.
Background technology
The certainty of measurement of temperature sensors of high precision is affected by manufacturing the many factors such as process deviation, encapsulation stress,
In order to reach the accuracy Design requirement of chip, it is necessary to the temperature sensor chip after Preliminary screening, encapsulation is calibrated.
The structure of existing temperature sensor calibration system, including temperature calibration system, thermometric instruments；Temperature correction
System is for gathering the measurement data of chip to be calibrated, and thermometric instruments is for gathering the operating ambient temperature of chip to be calibrated
Data.
The major defect of this structure is:
(1) thermometric instruments must be high-precision, and cost is high.
(2), in calibration process, the temperature probe of thermometric instruments is difficult to be combined well with chip to be calibrated and have
Same temperature environment.
(3) requiring that chip to be calibrated and test probe are immersed in liquid environment, building of this calibration environment is more complicated,
And owing to needs change calibration temperature to liquid heating, prover time is longer.
The Chinese invention patent application of Application No. 200810044099.X disclosed in 23 days June in 2010, it invents wound
Entitled " the calibration system of temperature sensor chip and the calibration steps " made, it includes test board, temperature calibration system；Test
Temperature sensor reference chip and chip to be calibrated it is provided with on plate；Each chip is by unified digital interface and temperature correction system
System connects communication.The temperature calibration system of the present invention, reads each chip to be calibrated and reference chip by unified digital interface
Temperature value；Each chip to be calibrated gathers data simultaneously, it is achieved that multi-chip data collection synchronous is calibrated, it is possible to be greatly improved number
According to collecting efficiency, reduce chip the detection calibration time, reduce calibration cost.Have simple in construction, easily build, prover time
Short, calibration efficiency is high, low cost and automaticity advantages of higher.
But, above-mentioned patent application is suitable only for the calibration of temperature sensor chip, and temperature sensor finished product needs again to seal
Dress, the temperature after encapsulation needs comparison again, calibration.It addition, after temperature sensor uses a period of time, can aging, drift
Deng.Therefore, it is also desirable to again calibrate.
At present, temperature sensor, in meteorology detects, carries important function, detects in outdoor temperature, extreme environment temperature
Degree detects has irreplaceable effect.The basic functional principle of Fibre Optical Sensor is through light by the optical signal from light source
Fine send into manipulator, after making parameter to be measured and interacting with the light entering modulator zone, cause optical property (strong such as light of light
Degree, wavelength, frequency, phase place, polarization state etc.) change, become the signal source modulated, send into optical detection through optical fiber
Device, is demodulated, it is thus achieved that measured parameter.Thus there is the advantage of a series of uniqueness, and as good in electrical insulation capability, electromagnetism interference energy
Power is strong, Noninvasive, high sensitivity, easily realizes the remote monitor to measured signal, and corrosion-resistant, explosion-proof, light path has flexible
Qu Xing, it is simple to couple with computer.It can be in place that people does not reaches (such as high-temperature region or the area that is pernicious to people, such as core
Radiation area), play the knowledge effect of people, and the physiological limits of people can also be surmounted, outside the sense organ of recipient is not felt by
Boundary's information.Therefore, Fibre Optical Sensor application in meteorology detects is more and more extensive.
The Chinese invention patent application of Application No. 201010576244.6 disclosed in 15 days June in 2011, it invents wound
Entitled " calibrating device for temperature sensor " made, it includes cavity, is full of heat-conduction medium, is provided with in cavity in cavity
Heater and temperature sensor, described heat-conduction medium is gas, is additionally provided with fan in cavity, and cavity is provided with temperature to be calibrated
Degree sensor insertion hole, temperature sensor to be calibrated is inserted and is provided with temperature sensor clamping device to be calibrated at hole.Fan is located at
Middle part in cavity, described heater is arranged around fan；Be additionally provided with air inlet and gas outlet on cavity, air inlet be provided with into
Valve, gas outlet is provided with air outlet valve, and the position of air inlet is located proximate to fan than gas outlet；Gas outlet and the ventilation in cavity
Road connects, the top suitable for reading within the cavity of described ventilating duct.
But, owing to temperature sensor and temperature sensor to be calibrated be not in same temperature field, therefore the temperature spot of detection has
Institute's difference, causes calibration data not accurate enough, and error is big.It addition, hot blast directly blows to temperature sensor surface, further result in
Temperature data test error is bigger than normal.
