Electric capacity, FPGA driving multichannel CDC (capacitance values converter) measurement be chosen region capacitance write down Cxy, corresponding to it
Pressure value is Fxy, scan successively and measure the capacitance of Intelligent cushion all areas, just obtain an automobile driver in intelligence
Pressure-plotting model M on energy automobile cushion.According to human physilogical characteristic, the ischium structure below basin bone can bear to compare
Larger pressure.Therefore preferably cushion pressure distribution should be that maximum pressure appears in the portion that seat contacts with ischium section
Position, pressure are gradually reduced centered on ischium section to surrounding, and pressure minimum appears in the portion of thigh and seat edge contact
Position, the pressure-plotting model M' of a standard sitting posture is established with this.Calculating standard sitting posture pressure-plotting model M' and measurement
Pressure-plotting model M Euclidean distance D=| M-M'|, using D as measurement pressure-plotting model to normal pressure distributed model
Departure degree basis for estimation.If having exceeded permission threshold value D' by D is calculated to be considered as human pilot sitting posture nonstandard,
Car body controller is then sent information to by bluetooth module, reminds driver to adjust sitting posture caused tired in driving procedure to mitigate
Labor.
Step 5：In driving procedure, FPGA driving high-speed ADC measurement piezoelectric membranes are defeated by corresponding signal processing circuit
The signal of collection is sent to microprocessor by the signal gone out, FPGA, and processor carries out basic function DB4 small echo to the signal of collection
Decompose, extract the heart rate after wavelet decomposition and breath signal.The fatigue state of human body of every five minutes measure is set,
Then the breathing of t and heart rate frequency are respectively a (t) and h (t), and the average breathing and heart rate frequency in five-minute period are
WithCalculate heart rate and the standard variance of breathing is respectivelyWith
WithBreathing and degree of fluctuation of the heart rate within this period of time are reflected respectively.General human pilot is in three when driving
Kind of state is normal, fatigue and neighbouring fatigue state.In normal state, heart rate, respiration wave are larger；Under critical fatigue state,
Breathing and heart rate volatility very little；Under fatigue state, heart rate volatility is gentle and has downward trend, breathes no significant change.So work asWithWhen be considered as human pilot and critical tired state occur, face once detecting human pilot
Boundary's fatigue state, intelligent automobile cushion send a signal to car body controller by bluetooth module, it is proposed that human pilot parking rest.
The utility model forms a flexibility by using PVDF piezoelectric membranes, flexible capacitor thin film and flexible circuit
Main seat body, four alcohol sensors are arranged on around main seat body, and these sensors pass through the mediate contact with tested personnel
Every physical parameter of human body is obtained, and each of tested personnel is calculated using FPGA and microprocessor signal handling capacity
Item physiological status.
When taking up, moved because the blood supply of human leg's artery and people's breathing cause that faint body can be produced, this
Slightly weak body is moved after being transmitted to piezoelectric membrane and may result in piezoelectric membrane output generation piezo-electric effect, and faint body movement signal is turned
Electric signal is melted into, ultimately results in the change of charge amplifier output voltage.This series of change is converted into numeral by high-speed ADC
Signal, because high-speed ADC is sampled with higher use frequency to this signal, it ensure that the complete of signal.Because breathing is believed
Number and the energy of heart rate signal concentrate on different frequency bands, remove outside noise using wavelet transformation can, and separate
Go out heart rate and breath signal.
Because the body weight of human body has been acted on intelligent mattress, the deformation of flexible capacitor thin film output, this shape result in
Become the change that result in electric capacity self capacity value, because different regional stresses is of different sizes, pass through all electricity of scanning survey
Capacitance, with regard to stress distribution of the human body on intelligent automobile cushion can be measured.In order to ensure the different densities pressure inside capacitor thin film
The connectivity of force snesor, the arrangement mode of 9*9,5*5,3*3 number these three density is have chosen in unit area, it is so horizontal
To and longitudinal flexible conductive tape can be directly connected between the array of pressure sensors of these three different density, extraction is led
Electric adhesive tape is connected to multiway analog switch, and the switching of microprocessor control analog switch selects each electrode, utilizes the electric capacity of multichannel
Digital quantizer measures all capacitances.
Alcohol sensor places four summits of Intelligent cushion respectively, and it can measure the alcohol concentration in air, is tested
If amount people drinks, due to the volatilization of alcohol, alcohol concentration can produce change around it.Due to being mounted with four sensings
Device, if the people to drink is not on Intelligent cushion, but the other positions in automobile, then due to alcohol volatilization center not
Again within four alcohol sensors, bigger difference just occurs in the output voltage of four alcohol sensors.Pass through this side
Formula just can differentiate it is that human pilot is drunk or other passengers drink.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as the scope of protection of the utility model.
