The hand grip portion of bearing circle 4 is provided with groove 31, and groove 31 is provided with the alcohol screen test box 3 that coincide with groove 31, and alcohol screen test box 3 is fixed on the bearing circle 4 by screw.Perhaps adopt another kind of embodiment: on direction indicators cover, have a window, alcohol screen test box 3 is fixed on the window place of dish cover.When direction indicators cover is enclosed within on the bearing circle 4, as long as with 3 alignment indentation 31 of the alcohol screen test box on the direction indicators cover and embed and the same a kind of embodiment such as get final product in the groove 31.
Alcohol screen test box 3 ends are provided with mini-fan 6, alcohol screen test box 3 surfaces are laid with breather hole 7, alcohol screen test box 3 surfaces are provided with polylith heating sheet 1 and trigger switch 2 with interval mode, and the sheet 1 that wherein generates heat is HTCC ceramic heating plate or PTC ceramic heating plate, and trigger switch 2 is for triggering sheetmetal.By Fig. 2 further as can be known, produce on the ceramic heating plate 1 and alcohol screen test box 3 surperficial breather hole 7 cooresponding breather holes 11, trigger on the sheetmetal 1 and also be laid with and the cooresponding breather hole 21 of alcohol screen test box 7 surperficial breather hole cloth, so that when assembling, the breather hole 11,21 on ceramic heating plate 1 and the triggering sheetmetal 2 can be corresponding one by one with the breather hole 7 on alcohol screen test box 3 surfaces.
Fig. 3 is a schematic block circuit diagram of the present invention.Wherein control circuit comprises crystal oscillating circuit, reset circuit and jtag interface circuit etc. based on the MSP430FG4619 micro controller system.12 built-in adc circuits of micro controller system are connected with signal receiving circuit, signal receiving circuit comprise decoding circuit, with decoding circuit bonded assembly bluetooth transceiving chip, power supply etc.The alcohol detection circuit comprises trigger circuit, signal conditioning circuit, filter circuit, signal transmission circuit.Signal transmission circuit comprise encode circuit, with encode circuit bonded assembly bluetooth transceiving chip, power supply etc.
In foregoing circuit, encode circuit PT2262 coding chip, cooresponding with it decoding circuit adopts the PT2272 decoding chip.PT2262/PT2272 is the general coding-decoding circuit of low-power consumption low price that a kind of CMOS technology of Taiwan Pu Cheng company production is made.
The bluetooth transceiving chip adopts TR0700 bluetooth transceiving chip, and this chip is a radio frequency/baseband chip that is suitable for short-distance wireless communication, and integrated level height, power consumption are little, and compatible bluetooth agreement fully can embed in any equipment that needs Bluetooth function.The Ignition Control end of micro controller system is connected with automobile igniting circuit.In addition, micro controller system also is connected with voice warning circuit, lcd drive chip, voice warning circuit adopts speech chip ISD1700, and chip for driving adopts lcd drive chip HT1621, and micro controller system drives Liquid Crystal Display (LCD) by chip for driving and shows various parameters in the testing process.
The input end of trigger circuit with trigger sheetmetal 2 and be connected, the source switch relay of trigger circuit be connected on power supply and the feeder ear of generate heat sheet 1 and alcohol detection and signal transmission circuit 5 and between.After hand touched triggering sheetmetal 2, trigger circuit just can be connected the power supply of alcohol detection and signal transmission circuit 5.
Fig. 4 is the schematic circuit diagram of signal conditioning circuit 9 and filter circuit 10.Wherein the high-accuracy amplifier MAX4238 of the U.S. letter of signal conditioning circuit 9 employings company production realizes that filter circuit 10 adopts the OPA603 integrated packages.The lead-out terminal of alcohol detection sensor 8 is connected with the signal input part of signal conditioning circuit 9, and signal conditioning circuit 9 is connected with filter circuit 10, and the mouth of filter circuit 10 is connected with encode circuit.
If after having drunk the chaufeur of wine and entering operator's compartment, chaufeur grasps the hand grip portion that touches bearing circle 4, the triggering sheetmetal 2 on alcohol screen test box 3 surfaces is responded to by body capacitance, start triggering circuit, and the relay energized by trigger circuit, so alcohol detection circuit and signal transmission circuit, heating sheet 1, fan 6 must be established beginning work by cable.After a period of time, heating and fan 6 at heating sheet 1 rotate under the negative pressure state that forms, a large amount of sweat steam that send from the centre of the palm enter in the alcohol screen test box 3 by breather hole 7, because alcohol content becomes specific proportionate relationship with the voltage signal that alcohol sensor 8 detects the back generation, after alcohol sensor 8 heating, survey controller and the gas signal that alcohol sensor 8 is surveyed is detected with regard to beginning.After alcohol gas sensor MQ3 detects alcohol, it is become voltage signal input signal conditioning circuit amplify, send into the encode circuit coding after the wave circuit filtering after filtration again, the data behind the coding are by the emission of bluetooth transceiving chip.
Bluetooth transceiving chip in the signal receiving circuit receives the alcohol detection data that send from the transceiving chip on the bearing circle 4, after the decoding circuit decoding, 12 ADCs built-in by micro controller system are converted to digital signal, by micro controller system to signal differentiate, relatively after, judge that whether the alcohol detection signal is above setting value.Suppose that alcohol content does not exceed standard, LCD Panel shows current alcohol concentration, and simultaneously normal indicator lamp lights, and control relay is inoperative, and automobile starts thereupon; Otherwise, then carrying out sound and light alarm, control relay cuts off the ignition device power supply, and navigating mate can't start automobile, fundamentally realizes controlling and drives when intoxicated.
