For checking the object of the invention, do following experiment in indoor:
Checking Beer-Lambert law (Beer-Lambert Law) and obtaining is used for the raw data of matching alcohol concentration and voltage logarithm value curve, and calibration slope A and intercept B value carry out the alcohol concentration value in inverting actual measurement under different voltage with this.
According to Beer-Lambert law (Beer-Lambert Law), a branch of monochromatic light exposure is in an absorbing medium surface, and by after certain thickness medium, a part of luminous energy due to Absorption of Medium, the intensity of transmitted light will weaken.The concentration of absorbing medium is larger, and the thickness of medium is larger, then light intensity weaken more remarkable,
Experimental procedure:
First the good every instrument of Installation and Debugging, accurately ensures that the FC flange-interface of air chamber is in a straight line, and opens laser instrument, the magnitude of voltage that when slow regulated attenuator changes initial, detector exports.
By preliminary experiment, we find that the laser intensity corresponding when voltage the is 4.883V error effect to experiment is less, are recorded in when not having alcohol gas, the magnitude of voltage of detector output.
Then the low concentration value that this system can detect is determined in experiment, and through testing discovery on the spot, system is that the response results of the alcohol gas of 12500ppm is good, in this, as the lower concentration values of experiment to concentration.
According to experiment low concentration value obtained above, (we adopt 0 to design standards concentration alcohol gas gradient, 12500ppm, 25000ppm ... 275000ppm is as testing the Grad taked), by calculating the alcohol content value corresponding to finite concentration gas, inject air chamber with the ethanol solution that concentration is accurately 99.7% by microsyringe.Closed air chamber, heats air chamber in outside simultaneously.Record laser continuously by air chamber by the magnitude of voltage after alcohol absorption, when voltage some values fluctuate up and down and without larger change time, can think that now alcohol is full of whole air chamber completely, the voltage of magnitude of voltage namely for this reason under alcohol concentration of correspondence.
Finally, use blowing facility that alcohol gas is blown out air chamber completely, can think when detector output voltage values with before survey magnitude of voltage when not having alcohol gas equal time, alcohol gas is blown out completely, and preparation is tested next time.
Repeat above-mentioned way, until the corresponding magnitude of voltage U of all normal concentration alcohol gas.Beer-Lambert law is utilized to demarcate A, B.
Data processing
By Labview to data analysis, fitting result is as follows:
Matching obtains
A＝-118.69301243 B＝185.91947693
Fitting a straight line is
C＝-118.69301243lnU(v)+185.91947693
Meansquaredeviationσ=2.501, coefficient R=-0.980399,
The LABVIEW program in actual measuring system that obtains thus transforms the relational expression of magnitude of voltage and alcohol concentration value:
C＝-118.69301243lnU(v)+185.91947693
In formula: v represents the frequency of light.
