Signal can obtain beats/per minute by R-R algorithms.It can obtain every by characteristic processing for acceleration and angular speed
The maximum and minimum value of group data (for example can be with one minute for one group).With reference to the data of daily workout, to acceleration and
The data of angular speed and heart rate set up training storehouse.Daily training include stand, run, walk, stair activity, forward fall,
The activities such as lateral tumble.After training storehouse to set up, when being submitted to for next Monitoring Data in master control.Pass through detection algorithm foundation
Train in storehouse and compare, obtain judged result.
Specifically, the data of daily workout here refer in advance it is known now whether fall in the case of obtain various
Acceleration information, angular velocity data and heart rate data under training, by acceleration information, angular velocity data and heart rate data with being
One-to-one relationship is set up between no tumble, an array can be regarded as, based on the principle that can be previously obtained up to a hundred
Thousands of groups of arrays, in actual applications, after the acceleration information, angular velocity data and heart rate data of user is got, pass through
Detection algorithm judges that this group of data and which array prestored are closest, closest in array whether tumble result is exactly
Final judged result.
As a kind of preferred embodiment, processing module 3 is specifically for judging whether acceleration of motion is more than default acceleration
Spend threshold value and whether heart rate signal is more than default heart rate threshold, if it is, judging that user falls, otherwise, it is determined that user does not have
Fall.
Certainly, it can also judge whether user falls by way of threshold value is set respectively here to simplify algorithm,
Directly judge whether acceleration of motion is more than predetermined acceleration threshold value and whether heart rate signal is more than default heart rate threshold, only
When acceleration of motion is more than predetermined acceleration threshold value and heart rate signal is more than default heart rate threshold, just it is judged to falling, otherwise,
Judge that user does not fall, equally improve the accuracy of judgement.
