Description
Technical field
The present invention relates to alcoholicity of exhaled gas detector (abbreviation alcohol content tester) Calibration Technology field, more particularly to
A kind of alcohol content tester calibrating installation that proof-spirit gas is produced using dry type alcohol gas and alcohol content tester calibrating side
Method.
Background technology
Alcohol content tester is traffic police instrument, belongs to a kind of measurement instrument, only by metrological service calibrating simultaneously
Obtaining the alcohol content tester of calibration certificate just has legitimacy.How alcohol content tester is examined and determineFirstly the need of there is proof-spirit gas
Body.It is divided into two kinds currently used for the proof-spirit gas of calibrating：Dry gas and moisture.So-called moisture, is simulated by wet type alcohol
The proof-spirit gas that device is produced.So-called dry gas, is the proof-spirit gas being mounted in steel cylinder prepared using weight method, by
There is no moisture, therefore referred to as dry gas in such alcohol gas.Because dry gas source tracing method is simple, therefore, our national regulations are used
Ethanol (alcohol) gas has card one-level gas reference material as the standard of tracing to the source in air.Dry gas is in steel cylinder with molar concentration
It is under certain atmospheric pressure, certain temperature conditionss, accordingly, it would be desirable to which molar concentration is changed in actual use to measure
Into mass concentration, by vertification regulation requirement, the concentration range of the proof-spirit gas used in calibrating alcohol content tester is：(0.1~
0.6) mg/L, three different proof-spirit gas concentrations and air (alcohol concentration is 0mg/L) totally four concentration conduct
Detectable concentration；Temperature in view of characteristics of contaminated respiratory droplets gas is generally 34 DEG C, and exhaled gas temperature can influence measurement result, therefore,
Needed proof-spirit gas thermostatic during calibrating to 34 DEG C ± 0.5 DEG C；Further, since the volume of characteristics of contaminated respiratory droplets gas, flow, exhaling
Measurement result can be influenceed by going out the factors such as time, be required according to vertification regulation, and the sample introduction flow of proof-spirit gas is not less than 15L/
Min, flow is adjustable, and the flowed fluctuation of sample introduction process is no more than 4%, meanwhile, the standard from alcohol content tester calibrating installation out
Gas should be able to simulate the exhalation process of human body, it is desirable to which the parameter such as volume, flow and expiratory duration of exhaled gas can basis
It is required that setting.
There is the alcohol content tester calibrating installation for meeting requirements above in the market.Referring to Fig. 1, a kind of existing
Alcohol content tester calibrating installation is made up of the computer 100 and main frame 200 for being mounted with control software, and main frame 200 passes through with computer 100
USB connecting lines are communicated, wherein, main frame includes：Power module, RS232 serial ports turns USB communication module, FPGA control
Device (PLC) processed, a heating tube, a mass flow controller (Mass Flow Controller, MFC), several electromagnetism
Valve, a large barometer and connecting tube；Several steel cylinders outside the main frame 200 are located to be connected to by corresponding magnetic valve
MFC。
During the existing alcohol content tester calibrating installation work：
By large barometer come the atmospheric value of measure field to be changed to molar concentration；The gas that a certain steel cylinder comes out
Body is directly heated by the heating tube of an about 30cm length, it is desirable to which the temperature of gas outlet is constant at 34 DEG C；Adjusted by MFC
Save expiratory gas flow, volume and expiratory duration.At least four alcohol concentration is needed during due to calibrating, to save cost, the program is only
The parameters such as gas flow are controlled using a MFC, select the steel cylinder gas of certain concentration all the way to pass through MFC by controlling magnetic valve
And heating tube, finally reach detected alkograph.There is problems with the program：
1st, the heating tube of 30CM length directly heats proof-spirit gas and is difficult to reach stationary temperature.The program uses diameter
Parcel heating wire is directly heated outside about 10mm, the copper pipe that wall thickness is about 1mm or so, because the heat of alcohol gas and copper pipe is passed
Lead that coefficient (thermal conductivity factor) is relatively low, and it is 3 seconds that at least 1.2L proof-spirit gas is most short by time of copper pipe, up to 15
Second, it is difficult to reach from room temperature (18 DEG C~28 DEG C) 34 DEG C ± 0.5 DEG C of control accuracy within the so short time.Due to general temperature
The heat capacity ratio for spending detection probe is larger, it is difficult to the temperature of the proof-spirit gas at quick directly detection inlet and outlet, so that
It is difficult to control heating process by feeding back, when room temperature changes between 18 DEG C~28 DEG C, the program from principle for it is difficult
It is constant at 34 DEG C ± 0.5 DEG C with the temperature for ensureing exit.
2nd, as shown in figure 1, steel cylinder 1, steel cylinder 2, steel cylinder 3, with steel cylinder 4 this four roads gas a MFC is shared, by controlling electromagnetism
Valve makes the proof-spirit gas in different steel cylinders enter the MFC to select different gas circuits, before being had when being changed due to gas circuit
The gas residue of one concentration, accordingly, it would be desirable to carry out gas washing.This can cause several point defects：First, switching steel cylinder gas is washed every time
Gas can cause time of measuring long；Secondly, gas washing can waste proof-spirit gas costly；3rd, gas washing can not be complete
The gas remained in wash clean pipeline, influences measurement accuracy；Finally, magnetic valve more or less has leakage, and multiple magnetic valves are very
Card is difficult to ensure without leakage or failsafe, gas is likely to result in when there is unconspicuous failure and is used with, measurement effect is influenceed.
3rd, computer and corresponding control software are needed, computer connects main frame by USB connecting lines, by sending control command
To control the parts such as MFC, magnetic valve, heating tube, it is well known that USB connections are after repeatedly plug, and it is unreliable to contact, often
Go offline, if gone offline when measuring, MFC, magnetic valve and heating tube will be out of control, caused to hold, blow that it is tight to cannot stop etc.
Weight failure.
4th, the alcohol gas of various concentrations needs to be selected on computer software, needs to be preheated after choosing, and waits
Time is short then more than ten seconds, long then a few minutes, less efficient.
5th, need to select corresponding gas concentration on computers before measurement every time, then perform gas washing, start the operation such as air blowing,
Four concentration operation interfaces are difficult to differentiate, and easily get wrong.
Therefore, it is necessary to design a kind of new alcohol content tester calibrating installation and use new alcohol content tester calibration method
To solve the above problems.
