Close algorithm and carry out face and eye recognition, estimate driver gestures angle using the methods of geometrical face model, and combine vehicle-mounted letter
The information of vehicles that breath module provides judges whether driver has and plays the associative operation behaviors such as steering wheel, is finally obtained according to behavioural analysis
The driver status threshold value arrived, the fatigue of comprehensive descision driver, divert attention or the state grade of anxious state of mind.
The state grade judged result of driver status judge module 13 is divided into three major types according to degree of danger, and they are
Well, it is bad and very bad, at the same it is good with it is bad between again segment out two state grades, it is bad with it is very bad
Between also segment out two state grades, so come to seven state grades.By taking driver fatigue state type as an example, if
Driver regains consciousness, then is " good " state；When feature of the driver with slight fatigue, but driving is not brought very big
Influence, then well to arrive two grades of bad；Start to change normally on vehicle when the fatigue of driver starts to be reacted to
When driving behavior, then be " bad " state；When the fatigue state of driver is increasingly severe, then it is presented as bad to very not
Two grades between good；When the fatigue state of driver continues deterioration and reached almost to lose normal driving ability, then for " very
It is bad " state.
The state grade that the driver status warning module 14 is sent according to driver status judge module determines needs
The alarm mode taken, and signal is passed into new line display module and sound alarm module.

Audible alarm module can start audible alarm.
Fig. 2 is block diagram alarm energy post display schematic diagram, is named as " energy post ".According to driver from well to very
Seven grades of bad state, devise seven width figures altogether.Every width figure is made up of three energy posts, with each energy of the change of state
Amount post can gradually change color, and energy post figure can be in complete green, Fig. 2 (a)；Complete orange Fig. 2 (d)；And between complete red Fig. 2 (g) constantly
Switch, energy post display representative " good " state in Fig. 2 (a), energy post display representative " bad " state, Fig. 2 (g) in Fig. 2 (d)
The display of middle energy post represents " very bad " state, Fig. 2 (b) energy posts into Fig. 2 (f) show represent respectively from " good " to
" bad " arrives the state of " very bad " change, example：Energy post color is green, green, yellow in Fig. 2 (b), and energy post in Fig. 2 (c)
Color is green, yellow, yellow, illustrates that " bad " state that Fig. 2 (c) is represented is more serious than " bad " state that Fig. 2 (b) is represented.
Driver status transition logic figure is illustrated in figure 3, describes the process of driver status transformation.Come back and show mould
The judged result that the energy post shown in block can provide according to driver status judge module dynamically changes color, if necessary sound
Sound alarm module can also start.By taking driver fatigue state type as an example, when driver status judge module judges driver's shape
State grade is " good ", then three energy posts are all green；When driver status judge module judges driver status for " no
It is good " and continue 5 seconds, 1 energy post begins to change into crocus, if driver status continues to remain " bad " and continues 5
Second, second energy post is changed into crocus, if the state duration of " bad " reaches 15 seconds, three energy posts are changed into
Crocus, afterwards, when driver status is judged as " good " and continues 5 seconds, 1 energy post becomes green again again, works as driving
Member's state continues to preserve " good " when reaching 5 seconds, and second energy post also becomes green again, and this " good " state continues 5 seconds again, and three
Root energy post is all changed into green again.
When three energy posts are all crocus, driver status judge module gives " bad " state and holding 5 again
Second, an energy post can be changed into red, if driver status continues as " bad " and continues 5 seconds, second energy post can become
Red, by that analogy, if the state duration of " bad " reaches 15 seconds, three energy posts are changed into red, driver's shape
State enters " very bad " state；When driver status enter " very bad " state, i.e.,：Energy post is three red columns, and
And continue driver status in 3 seconds and do not improve also, then three energy posts start to flash, and driver does not react still after flicker 3 seconds,
Then sound early warning is sent while energy post flashes.
