Hereinafter principle of the present utility model is further elucidated with:
Cleaning Principle firstly, for seat belt and fatigue driving:
In order to driver and crew's whether wear safety belt accurately be detected, seat belt is coated reflectorized material, therefore, camera collection to image in, the brightness not being that human body fastens one's safety belt is apparently higher than other parts, the ratio (being referred to as bright spot ratio) of image processing circuit area with total image area by calculating the high-brightness region of the image collected, to judge whether seat belt is worn or vacation is fastened the safety belt, has equation below:
According to actual experiment data (as shown in table 1) to judge the wearing state of seat belt:
Table 1
In actual applications, under normal wear condition, bright spot ratio is generally higher than or equal to 7.5%, if bright spot ratio is less than 7.5%, there is vacation and wear phenomenon or do not wear seat belt；
Cleaning Principle for fatigue driving:
The state of fatigue driving Main Basis eyes detects, i.e. PERCLOS detection method (percentageofEyelidClosureoverthePupil, the abbreviation of overtime), it is defined as in the unit interval time shared by (generally taking 60S or 30S) eyes closed certain proportion (70% or 80%), meets equation below:
When, after system lock driver eye, starting to measure driver PERCLOS, i.e. the unit interval interior time shared by (taking 40 seconds herein) eyes closed certain proportion (70% or 80%)；The evaluation criteria of PERCLOS is:
Eyelid covers the area of pupil and is just calculated as eyes closed more than 70%, add up within a certain period of time eyes closed time
Eyelid covers the area of pupil and is just calculated as eyes closed more than 80%, adds up time scale shared during eyes closed within a certain period of time.
Eyelid covers the area of pupil and exceedes half and be just calculated as eyes closed, adds up time scale shared during eyes closed within a certain period of time；
Therefore, the judgement equation below of fatigue driving:
And as in figure 2 it is shown, the standard value of PERCLOS sets as illustrated, it can be seen that standard value and driving time have relation, namely different durations of driving takes corresponding PERCLOS standard value.
Hereinafter operation principle of the present utility model is described:
When after vehicle startup, entire car controller sends vehicle launch signal to central processing circuit, central processing circuit controls photographic head and light compensating lamp enters duty, certain light compensating lamp needs to step on work when environment light is not enough, image processing circuit detection driver and crew's whether wear safety belt, without wearing, testing result is sent to central processing circuit, central processing circuit then reminds driver and crew's wear safety belt by voice prompting device, if it exceeds the setting time remains without and wears or be in vacation and wear state, then central processing circuit is reminded by flashing indicating device, other vehicles are allowed to note travelling, if and not wear safety belt or be constantly in vacation and wear state, central processing circuit is sent a warning message to traffic control center by GPRS circuit, including license plate number and seatbelt wearing information；
nullDetect that driver and crew's wear safety belt is worn when speed exceedes，Safety detection warning module enters into fatigue driving detection state，Driving condition according to above-mentioned PERCLOS detection method detection driver，If there is fatigue driving state in driver，Image processing circuit is to central processing circuit output detections result，The concentration value that central processing circuit exports according to current carbon dioxide sensor exports control command to entire car controller，The vent controlling vehicle is opened，And central processing circuit controls vibrating prompt work，Thus two ways combines guarantees that driver keeps waking state，Central processing circuit and export information by voice prompting device，Allow driver and crew find safety zone parking nearby have a rest，And flashing indicating device works，Prompting surrounding vehicles maintains safe distance，If it exceeds the time set，Driver is still within fatigue state and drives，Then central processing circuit carries out, to traffic control center, report to the police (image information that this warning message should include the current vehicle trade mark and driver fatigue state) by GPRS communication module，Driver is forced to carry out rest of stopping by laws and regulations means，Unlawful practice can be punished by traffic control center accordingly，Thus strengthening the mandatory of execution.
What finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described in detail with reference to preferred embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, without deviating from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
