The information of all inputs passes through microprocessor 5, is processed, handles.Controlled and shone according to the data of photosensitive sensor 4
The automatic opening of bright lamp 6 and angle adjustment；
According to the positional information of driver's face, the shooting orientation of the regulation camera 3 of camera position adjuster 8 is utilized.
Judge the timing of driver's emotional lability in microprocessor 5, motor vehicle refusal igniting is controlled using ignition controller 9.
Its device is specific as shown in Fig. 2 in-car mainly include left front illuminating lamp 10, right front lamp 11, and camera 3 is left
Rearview mirror 13, right rear view mirror 14, steering wheel 15, pilot set 16, the passenger side seat 17 and car door 18.
Pressure sensor 1 is arranged under pilot set 16, and sensed pressure judges whether there is driving on pilot set 16
Member, if any then automatically turning on Intelligent voice dialog system 7.
Photosensitive sensor 4 perceives in-car light intensity, and illuminating lamp 6 is made up of left front illuminating lamp 10 and right front lamp 11,
Left front illuminating lamp 10 and right front lamp 11 are positioned on the upper left side and upper right side of driver's cabin, bad at night or in-car light
In the case of automatically turn on, camera 3 is preferably gathered image information.

Reference picture 3, according to the utility model, after driver gets on the bus, pressure sensor 1 perceives the pressure on seat,
Automatically turn on Intelligent voice dialog system 7.Automatically turn on Intelligent voice dialog system 7 can shuffle go out laughing at of first prestoring
Words, or broadcast first sad story.Or based on the question content to prestore, engaged in the dialogue at random with human pilot, right
In the content of words, happy thing, sad thing can be related to as the case may be.Such as following scene：
Scene one：Intelligent voice dialog system 7：" your good owner, it is very happy to meet again！Why may I ask your mood of today
Sample”
Problem answers synchronously show can there is several options on liquid crystal display 19, and driver inputs in selection way
The answer of the asked questions.
Scene two：Intelligent voice dialog system 7：" your good owner, it is very happy to meet again！Why may I ask your mood of today
Sample" if driver replies the in high mood of today, possible Intelligent voice dialog system 7 can ask：" owner runs into today
What happy thing, could share with me, it is a robot that not see me ".Next may say：" owner,
You want to go to where" and then may ask that " you intend go there what does”
Scene three：Intelligent voice dialog system 7：" Hello, hello by owner, and I has learned to tell funny stories recently, owner I say
Listened to you ".Then can ask：" owner, you think that I say how”.Next may ask：" owner, you are disagreeable
People whom isMe is stealthily told, I can never tell others ".It may finally allow driver to imitate most to beg for
Some features of the people detested.
During, all facial expression informations are gathered using camera 3, this information is delivered into microprocessor 5 is carried out
Human facial expression recognition, analysis, processing.Thus judge whether the driver can now drive, when driver speaks, voice meeting
Being identified at once, voice will be immediately encoded, and turn into the digital document of a compression, wherein all useful information are included,
All will be by Intelligent Recognition.
In dialog procedure, the facial expression of driver will carry out head portrait acquisition by camera 3, then pass through detection
Module is detected to the image of input, and the possible orientation of face is scanned in the picture, identify, positioned.Pass through inspection
Survey module and obtain the face-image without background, and have indignation using this as research object, the basic mood of people, detest, probably
Fear, it is happy, it is sad and surprised.And the human facial expression recognition system in microprocessor 5, it is to resolve into the facial expression of driver
Multiple Facial action units, these independent facial units can not represent any emotion, but utilize combinations thereof special
Sign can carry out the identification of some facial expressions.
For example, if driver has only affected greater zygomatic muscle when laughing at, then, now driver is exactly certainly phoney,
Because a sincere smile is in addition to greater zygomatic muscle, also orbicular muscle of eye can also be affected.Other expressions are in this approach
It can judge.When the expression for identifying driver is sad, angry or abnormal exciting.Voice system will be reported：
" sorry, you do not allow now to drive " and close automobile engine now.
The method of speech recognition is after microphone collects acoustic information, first by voice signal be converted to electric signal be added in it is micro-
The input of processor, by pretreatment, pretreatment is the pre-filtering processing that voice signal is carried out before sampling, suppresses signal
Interference components in each frequency；Speech model is established further according to the characteristic voice of people, the voice signal of input is analyzed, and takes out
Required feature is taken, establishes the template needed for speech recognition on this basis.System will be according to speech recognition in identification process
Model, by the sound template deposited in system compared with the feature of the voice signal inputted, according to certain search and
Matching strategy, find out a series of optimal templates with inputting voice match.Then according to the definition of this template, by tabling look-up just
The recognition result of system can be provided.
Human facial expression recognition technical basis expression storehouse, expression storehouse not only can provide material for Expression Recognition algorithm, and
Foundation can be provided for the performance test of various algorithms.The method of human facial expression recognition is to catch identification people first with camera
Face, then system to form face-image pixel analyze.It is compared the shading value of each pixel with consecutive points
Compared with region of the lookup shading value to surrounding in radiomutation.In the feature of brow ridge, eyes or other projections.System will be sketched the contours
Go out the position of each this pixel.Specific algorithm is:It is empty that the head portrait that the first step collects to shooting figure first carries out color
Between conversion, row pixel and row pixel are set.Second step：Compareed with the expression storehouse of system, calculate average and covariance.3rd
Step：Calculate barycenter and deflection angle.4th step：Find out the border of image-region.5th step：Seek origin coordinates.6th step：Enter
The matching of row template, produce the gray level image of a covering face.
In the entire system, intelligent voice system, human facial expression recognition system and automobile engine triplicity are got up,
In order to accurately collect the facial information of people, the special front that camera 3 is arranged on to driver.In order to facilitate night
Image information can be preferably collected, one illuminating lamp is installed respectively on the upper left side of automobile cab and upper right side, illuminated
Used in the case that situation is bad.
Fig. 4 is the utility model on-board engine firing circuit figure, main to include by crystal oscillator X1, ceramic disc capacitor C1
Clock oscillation circuit is formed with ceramic disc capacitor C2, clock oscillation circuit provides clock signal for LPC2103.Electrochemical capacitor C4 and electricity
Hinder R1 composition LPC2103 electrification reset circuits.On-board engine firing circuit is installed on motor vehicle.Mainly by relay RL1,
Triode Q1, resistance R2 and wait structure crystal diode D1 form, when relay in coil without it is electric when, off-state touch
Point is that normally opened contact, the contact of closure state are normally-closed contacts, when the information judged via human facial expression recognition system is this
Driver fails by test, and when disapproving operating motor vehicles, microprocessor control relay makes its contact be disconnection form, hair
Motivation can not be activated, conversely, when human pilot has passed through test, when allowable drivers drive, microprocessor control relay
Device contact is closed form, now lights a fire, starts function to be activated.
