Intelligent seat is in listening mode, and when there being user to use, it is soft that pressure transducer 22 detects user contact Pressure during pad 10, and this pressure is converted into digital signal, i.e. pressure sensor signal, microprocessor module 23 detects pressure Transducing signal, switches to mode of operation, otherwise, then judges that no user is sat on the seat, keeps listening mode.Attitude transducer 21 detect seat attitudes vibration and are translated into digital signal, as shown in figure 5, with intelligent seat support center as initial point, Set up coordinate system xyz, the acceleration measuring in attitude transducer 21 measures the accekeration (a on tri- direction of principal axis of xyz_x, a_y, a_z), take on the occasion of when be positive along coordinate axess, taking during negative value is along coordinate axess negative sense, the gyroscope measurement in attitude transducer 21 Go out the magnitude of angular velocity (GYR_X, GYR_Y, GYR_Z) on tri- direction of principal axis of xyz, take on the occasion of for clockwise, taking negative value to be inverse Clockwise, microprocessor module 23 is to accekeration (a_x, a_y, a_z) and magnitude of angular velocity (GYR_X, GYR_Y, GYR_Z) counted Calculate, concrete calculating process is as follows：

To accekeration (a_x, a_y, a_z) decomposed, respectively obtain

Pitch angle：

Left and right rolling angle：

GYR_Z in angular velocity value (GYR_X, GYR_Y, GYR_Z) is integrated, and obtains anglec of rotation λ₀；

Obtain attitude angle data ω₀、And λ₀, and as shown in figure 5, direction direction shown in arrow along along Fig. 5 is just Value, i.e. ω₀Angle layback direction be on the occasion of,Angle Right deviation direction is on the occasion of λ₀Angle clockwise direction be on the occasion of.

Because the geographic area that measurement is located is different, vibrations or ambient temperature are different, and attitude transducer 21 detects There is certain deviation with actual value in accekeration and magnitude of angular velocity, therefore calculated attitude angle data is deposited with truthful data In certain deviation, the attitude angle data of output contains substantial amounts of noise, accordingly, it would be desirable to extract signal in noise, that is, Need to find a kind of wave filter having optimum linear filtering characteristic, this wave filter, when signal is simultaneously entered with noise, is exporting Signal can be reappeared out by end as accurately as possible, and noise is subject to maximum suppression.

Kalman filter is adopted, Kalman filter is the recursive filtering for time-varying linear systems in the present embodiment Device, this system can be described with the Differential Equation Model comprising quadrature variable, and this wave filter is by the measurement in past Estimation difference is merged into the error to estimate future in new measurement error, observes data by system input and output, to system State carries out optimal estimation.Kalman filter operation principle is as shown in fig. 6, detailed process is as follows：

Kalman filter can be represented with a linear random differential equation：

X (k)=A X (k-1)+B U (k)+W (k) (3)

System measurement equation is expressed as：

Z (k)=H X (k)+V (k) (4)

Wherein, X (k) is the system mode in k moment, and U (k) is the controlled quentity controlled variable to system for the k moment, A and B is systematic parameter, For Multi-model System, they are matrix, and Z (k) is the measured value in k moment, and H is the parameter of measuring system, for many measurement systems System, H is matrix, and W (k) and V (k) represents process and the noise of measurement respectively, and they are assumed to white Gaussian noise, their association Variance is Q, R respectively, and assumes that they do not change with system state change.

Kalman filter system work process is as follows：

System mode is k now, according to the model of system, can be predicted and be occurred in shape based on the laststate of system State：

X (k | k-1)=A X (k-1 | k-1)+B U (k) (5)

In formula (5), and X (k | k-1) it is the result predicted using laststate, X (k-1 | k-1) it is the optimum knot of laststate Really, U (k) is the controlled quentity controlled variable of status praesenss, and due to not having controlled quentity controlled variable, this value is 0.

Represent covariance with P：

P (k | k-1)=A P (k-1 | k-1) A '+Q (6)

In formula (6), P (k | k-1) is X (k | k-1) corresponding covariance, and P (k-1 | k-1) is X (k-1 | k-1) corresponding association Variance, A ' represents the transposed matrix of A, and Q is the covariance of systematic procedure.Formula (5), (6) are in Kalman filter to system Prediction.

Next step, in conjunction with predictive value and measured value, obtains the optimization estimated value X (k | k) of status praesenss (k)：

X (k | k)=X (k | k-1)+Kg (k) (Z (k)-H X (k | k-1)) (7)

Wherein Kg is Kalman gain：

Kg (k)=P (k | k-1) H '/(H P (k | k-1) H '+R) (8)

Optimum estimated value X (k | k) is obtained under k-state by formula (7), next step updates the association of X under k-state (k | k) Variance：

P (k | k)=(I-Kg (k) H) P (k | k-1) (9)

Wherein I is 1 matrix, because model is single measurement, I=1.When system enters k+1 state, and P (k | k) it is exactly formula P (6) (k-1 | k-1), system update process is realized by autoregressive operation.

It is assumed that measured value is even variation in the present embodiment, from microcosmic, self-consistentency at short notice, and do not have Any artificial control, thus A=1, because there is no controlled quentity controlled variable, U (k)=0, the data of sensor measurement output is subject to temperature Or the impact waved, the noise of generation is the white Gaussian noise that a summation is 0, thus H=1, therefore, Kalman filter system System work process equation can be reduced to following form：

X (k | k-1)=X (k-1 | k-1) (10)

P (k | k-1)=P (k-1 | k-1)+Q (11)

X (k | k)=X (k | k-1)+Kg (k) (Z (k)-X (k | k-1)) (12)

Kg (k)=P (k | k-1)/(P (k | k-1)+R) (13)

P (k | k)=(1-Kg (k)) P (k | k-1) (14)

When system enters k+1 state, P (k | k) is P in formula (11) (k-1 | k-1), that is, pass through autoregressive operation Realize system update process.

In the present embodiment, the input signal of input Kalman filter is attitude angle data ω₀、And λ₀, be output as through Cross denoising stable attitude angle data ω,And λ.Intelligent seat is pressed certain time interval detection seat attitude and is become Change, in the present embodiment, choose 5 minutes for a time interval, after the kinestate denoising that time interval previous moment detects Attitude angle data be ω 0,With λ 0, the attitude angle number of degrees after the kinestate denoising that time interval later moment in time detects According to for ω 1,With λ 1, prestore in memory module or angle threshold that user is set by threshold setting module is as ω th、With λ th,Represent in memory module and prestore or diagonally forward that user is set by threshold setting module 27 Angle judges angle threshold, and angle threshold is on the occasion of microprocessor module 23 by stable angle-data and represents anterior-posterior horizontal State, the numerical value 0 of left and right horizontal state and the last rotation angle value obtaining compare and draw current pose, further , stable angle-data is set by threshold value by microprocessor module 23 with angle threshold default in memory module or user The angle threshold putting module settings is compareed, the corresponding attitude information of the different amplitude of output, and this threshold value is to be built based on statistics Vertical, concrete differentiation process is as follows：
