Removable gas detection cell 1 of the present utility model can be changed by certain access times, pulls down sensor cover 9, backs out screw and just can take down removable gas detection cell 1 replacing.When using or change removable gas detection cell 1, need import a string correction codes, to keep the state of removable gas detection cell a calibration.
As shown in Figure 6, gas detection cell realizes proofreading and correct by external calibration equipment, and this work is by factory or service centre's operation, and the user does not need to do.Wherein removable gas detection cell is connected on the calibration equipment, use the alcohol gas of various criterion concentration in order respectively, blow alcohol gas from removable gas detection cell, after having blown at every turn, calibration equipment and removable gas detection cell cooperate, produce outputs such as voltage, electric current or frequency, deliver to the chip assembly of calibration equipment and handle, the hexadecimal code of a correction usefulness can appear in calibration equipment.
It below is a kind of feasible correction example, after at first proofreading and correct by the concentration order, in the control panel of calibration equipment, check the correction codes menu, the correction codes (concentration is that the correction of 0.1 ‰ BAC is drawn according to test result calculations by test macro) of top five kinds of concentration gases occurs.Can provide the correction codes (ID code) of five kinds of these removable gas detection cell under the alcohol gas concentration on the control panel simultaneously, the correction codes of removable gas detection cell is six sections sexadecimal numbers, the first five section is the correction codes of five kinds of concentration gases, and the final stage system-computed draws.
The correction codes form of removable gas detection cell is:
Xxxx-xxxx-xxxx-xxxx-xxxx-xxxx (x is the sexadecimal number)
For example:
1111-2222-3333-4444-5555-ABFC
Wherein 1111 is the correction codes that produce according to the alcohol gas data of 0.2 ‰ BAC concentration
2222 is correction codes of the alcohol gas of 0.2 ‰ BAC concentration
3333 is correction codes of the alcohol gas of 0.5 ‰ BAC concentration
4444 is correction codes of the alcohol gas of 0.8 ‰ BAC concentration
5555 is correction codes of the alcohol gas of 2.0 ‰ BAC concentration
ABFC is the correction codes of the interior CPU of calibration equipment circuit according to the correction codes generation of five kinds of concentration, and concentration progressively raises, and six groups of numerical value are progressively to increase.
The correction codes ID of this removable gas detection cell is output on paper, printed material or the imprinting material, and shown in Fig. 7 (a) and Fig. 7 (b), is marked on the wrappage of removable gas detection cell or on the removable gas detection cell.
This correction codes is represented resistance or the magnitude of voltage of removable gas detection cell under each concentration, otherwise knows resistance or magnitude of voltage under certain concentration point, just can instead release current gas concentration.
Each removable gas detection cell is being fixed with resistance value under the concentration or voltage, and resistance fixing under a plurality of concentration or magnitude of voltage are demarcated, and becomes the standard scale of each removable gas detection cell, and this process is called calibration or proofreaies and correct.Removable gas detection cell is added round-off error at the resistance or the magnitude of voltage of individual concentration point, above said correction codes.
Each removable gas detection cell has special-purpose correction codes, cannot change use.The correction codes of each removable gas detection cell must this removable gas detection cell of coupling.
The alcohol concentration scope of removable gas detection cell is proofreaied and correct by top method according to client's needs, shows or prints the setting of realization alcohol correction data, and do not need to be provided with the data that memory device is stored correction again on gas detection cell.
As shown in Figure 8, do not need when the user operates to go adjustment with alcohol gas again, only need after the removable gas detection cell installation, one group of code of input just can use on screen.Using method: when the user connects the back (socket, blowpipe and the removable gas detection cell that comprise 20Pin) that finishes with hardware, start shooting to be introduced into system's adjustment master menu of this gas measurement instrument, enter again alcohol screen test be provided with in emat sensor menu more.
Just entered this menu, screen top shows is the correction codes of the sensor of old removable gas detection cell, be that 0 to F touch digit order number and control touch the position below, use the felt pen touch screen, with the correction codes on this removable gas detection cell packing: xxxx-xxxx-xxxx-xxxx-xxxx-xxxx, as above the 1111-2222-3333-4444-5555-ABFC in the example is input on the screen, after (middle "-" need not import) all is totally lost, determine by twice " OK " continuously, cover the data of old removable gas detection cell, withdraw from this menu automatically.Just the correction codes of input is stored in the storer of gas measurement instrument information process unit, and the storer of information process unit is also stored the testing time of gas measurement instrument, parameters and the password that the user is provided with simultaneously.Accomplish the maximum projects of same memory stores, avoided in removable gas detection cell, being provided with the cost increase that storer brings, the connection complexity of each unit, the problem of software programming inconvenience.
Because each removable gas detection cell was all done the test in the resistance value of 4 concentration point before dispatching from the factory, formed standard scale, removed to test tested gas with this yardstick, just can instead release current gas concentration.
Be stored in the correction codes in the storer of information process unit of gas measurement instrument, exactly the standard scale of the demarcation under factory mode.Therefore new removable gas detection cell is changed and is finished, and just keeps the state of removable gas detection cell a calibration, just can use, and need not the user and demarcates in each concentration more again.Used replaceable gas detection cell can be with behind calibration equipment calibration again, new correction codes is input to just can repeats in the information process unit repeatedly to use.
Above-mentioned example, input method are that touch-screen is input to this gas measurement instrument, actual button or the photoscanner input that also may adopt instrument.Correction codes also can adopt the form of bar code, also can imprinting on subsidiary CD.
In the embodiment of above utility model, the program by calibration equipment and software cooperates, and with the printable output of correction codes, can replace the patch memory on the replaceable gas detection cell of the smart measuring instrument of traditional wine, provides cost savings and volume.Simultaneously, the utility model is with function integrations such as slot machine (or machine for punching the card), alcohol content measuring technique and MP3 players, with heating data acquisition, the treatment technology combination of low power consumption sensor, draw the gas measurement instrument of a kind of novel structure, precision height, multi-functional, replaceable gas detection cell.Attendant printer function and MP3 power amplifier can be play mobile film function and throw in as building advertisement.It finishes popular demand by charge unit and information process unit cooperating.
Above with reference to description of drawings preferred embodiment of the present utility model, those skilled in the art do not break away from essence of the present utility model and spirit, can have multiple flexible program to realize the utility model.The above only is the preferable feasible embodiment of the utility model, is not so limits to interest field of the present utility model, and the equivalence that all utilization the utility model instructionss and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
