Description of drawings
Fig. 1 is system of the present utility model composition diagram.
Fig. 2 is main program flow chart of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of safety control of driving when intoxicated of preventing comprises dsp controller 1, alcohol sensor 2, AD converter 3, relay 4, power interface 5, LCD touch-screen 6 and voice module 7; Alcohol sensor 2 is connected to dsp controller 1 through AD converter 3, and the signal that alcohol sensor 2 collects is sent to dsp controller 1 after AD converter 3 conversions; Dsp controller 1 is connected to relay 4, and relay 4 is connected between vehicle power and the engine starting power supply, and dsp controller 1 is judged through relay 4 to cut off the startup power supply of driving engine according to pre-set programs; Power interface 5 is connected with LCD touch-screen 6 with dsp controller 1; Vehicle power is given dsp controller 1 and 6 power supplies of LCD touch-screen by power interface 5; Dsp controller is connected with vehicle-mounted CAN bus 8, becomes one with on-vehicle control apparatus.
It is TMS320C6713 type DSP that dsp controller 1 is selected model for use; Alcohol sensor 2 is selected HS-3C type sensor for use; It is the conv of AD574A that AD converter 3 is selected model for use; Relay 4 is selected Siemens 3TH type intermediate relay for use; LCD touch-screen 6 is selected 7 cun LCD touch-screens of DUER-0700-W4R-D type for use; Voice module 7 is selected the ZY1420 voice module for use.
HS-3C type alcohol sensor uses electrochemistry type fuel cell, and characteristics are quick response, little, low in energy consumption, the miniaturized design of humiture influence.Control the action of auto activation engine system by the detected alcohol concentration of alcohol sensor, according in the blood of human body with breath in ratio (2000～2100) decision person's the drunk degree of alcohol concentration, China is 10～30g/100L (alcohol concentration in the blood) to the decision boundaries of drunken driving, when detecting BAC less than 20g/100L, normal start the engine, when reaching 20g/100L when above, just can not start the engine.
It is monolithic 12 comparison A/D convs one by one at a high speed of U.S. analog digital company (Analog) that AD converter adopts AD574A, this conv.The hybrid integrated chip that it is made up of analogous circuit and digital circuit.Can automatic zero adjustment and the auto polarity conversion, do not need peripheral buffer circuit, can be directly and 8 or 16 bit processor interfaces, can in 25Ls, finish once and change.
Phonetic alarm is selected the ZY1420 voice module for use, controls the voice memory segment control function of this voice module by level switch.
Relay adopts Siemens 3TH intermediate relay, and this relay adopts E shape iron core, the Direct Action Type motion structure of double break point bridge contact system, reliable in action; Contact is the bridge-type double-breakpoint structure, and contact material is made by the silver alloy of superior electrical property, has long service life and excellent contact reliability.This relay also meets standards such as IEC947, VDE0660, GB14048.Therefore, be used in this device and can control engine starting well.
With reference to Fig. 2, the main program of this device comprises sensor input, data acquisition, data processing, voice suggestion and driven element program etc.Wherein thereby the function of dsp controller is to drive actuating of relay control engine starting; Data acquisition program is delivered to the data that receive in the A/D converter and is handled, and digital signal is input in the dsp controller; A part is sent to the LCD touch-screen and is shown, a part compares with setting value in addition, and when it surpassed calibration value, phonetic alarm prompting chaufeur was driven dangerous, makes its enhancing your vigilance property, and the action of control relay can not start car engine simultaneously.
With reference to Fig. 2, at first system is carried out initialization, data acquisition module is handled with logic the sensor signal that receives and is judged, and alcohol concentration is shown with the LCD touch-screen.Compare through digital signal and calibration value after the AD conversion, if less than calibration value, carry out the action of relay, namely drive relay and cut off driving engine, continue then alcohol sensor is carried out data acquisition; If greater than calibration value, do not carry out the actuating of relay, continue sensor signal is gathered, the chaufeur of phonetic alarm prompting is simultaneously locked car, shut-down operation.
