Duan Jinhang identifying processing, wherein each section with regular length is known as a sliding window, which is known as sliding
The width of window needs to predefine.There is overlapping between adjacent sliding window, the latter sliding window abandons previous
First data of sliding window, and a new data are added in tail portion, rest part is identical.
As shown in fig. 7, being initialized first, into wait state, judge whether time-out, the recognizer knot if time-out
Beam, if it is not, then further determining whether to reach the sampling period.If the not up to sampling period, return is continued waiting for, and is adopted if reaching
The sample period then carries out ADC sampling to gyroscope, and the data that sampling obtains are put into sliding window after the last one data
Face.Judge whether sliding window is filled, continued waiting for if it is not, then returning, if so, a pair using following two methods is sliding
Dynamic window carries out identifying processing.If being judged as, user locks a door, and recognizer terminates；If it is not, then further determine whether for
It opens the door at family.If so, recognizer terminates；If it is not, first interrupt identification then abandoned in sliding window makes at sliding window
In discontented state, then returns and continue waiting for.Since the processing capacity of single-chip microcontroller is limited, identify that the number of operation is relatively more,
Sliding speed v can be set in practical applications, i.e., for v sliding window of arbitrary continuation, first 1 sliding window is known
Not, continuous v-1 sliding window below is abandoned.
For sliding window, following two method can be used and carry out identifying processing:
Method one is that DTW algorithm (Dynamic Time Warping, dynamic time consolidation) and two kinds of k neighbour are used in combination
Algorithm.
Need to store the locking a door of equivalent in single-chip microcontroller in advance, open the door and the sliding window mode time sequence of noise and its
Corresponding mark, as training data.When being identified, the sliding window w obtained in use and instruction are measured with DTW algorithm
Practice the distance between the time series in data, take wherein k and w form k neighbour set apart from the smallest training data.Again from
The most mark of quantity is selected in k neighbour set as identification as a result, can also directly use distance in k neighbour set minimum
Time series mark as recognition result.
Method two is the method based on artificial neural network.
Sliding window is input in feedforward neural network and is identified.The number of nodes of the input layer of feedforward neural network
It is of same size with sliding window；The number of nodes of hidden layer can be rule of thumb configured, such as may be configured as the section of input layer
The 2/3 of point quantity；Output layer includes two nodes, respectively o1And o2；Work as o1Output is 1 and o2When output is 0, it is judged as use
It locks a door at family；Work as o1Output is 0 and o2When output is 1, it is judged as that user opens the door；Other situations are then judged as noise.Feedforward Neural Networks
The training method of network is back-propagation algorithm, training set be process manually mark lock a door, open the door and Time sequence of noise, wherein
It locks a door and corresponding is labeled as o1=1 and o2=0, enabling is labeled as o1=0 and o2=1, noise is corresponding to be labeled as o1=0 and o2=
0。
Both the above method operand is larger, is suitble to use the faster single-chip microcontroller of arithmetic speed, need using longer window
Mouth width degree, can also be without using sliding window and using obtaining preferably to reflect feature that data have in this wakeup process
