If gauger's hand-hold electronic equipments measure the respiratory rate of measured, it is most likely that cause to surpass because of the shake of gauger's hand
Clutter is mixed into sound wave, it is therefore necessary to be filtered to ultrasonic wave；
S204：Within a preset period of time to the chest of measured send it is filtered after ultrasonic wave, wherein preset time
The length of section breathes the time of preset times at least more than the measured；
For example, if preset times are 20, the length of preset time period be at least greater than measured's breathing 20 this when
Between.Certainly, preset time period is longer, and the respiration rate that can be measured is more, therefore obtained measurement result is more accurate.
In practical applications, the length of preset time period can be set according to the actual demand to measurement result.
S205：Back wave is received by least two ultrasonic receivers on the electronic equipment, described at least two
Ultrasonic receiver is arranged in the Different Plane of the electronic equipment；
For example, as shown in figure 3, ultrasonic receiver MIC can be 4, one of them is located at same with ultrasonic transmitter
One plane, other 3 be located at where ultrasonic transmitter in different plane.
S206：The back wave received is filtered；
The purpose that back wave is filtered is to filter out the clutter in back wave, to improve the accurate of measurement result
Property.
S207：Respectively according at least two back waves after filtered each back wave and the ultrasonic wave group
At combination, calculate the changing rule of the predetermined patterns occur with breathing in the preset time period displacement, obtain
At least two reference change rules；
S208：According at least two reference changes rule, the predetermined patterns described in the preset time period are determined
The changing rule of the displacement occurred with breathing；
Specifically, a mean change rule can be obtained, as what is determined according at least two reference change rules
Final changing rule.
Because the chest of measured is a three-dimensional spatiality, and ultrasonic wave is in three-dimensional space (when not considering
Between) in propagated, so, back wave is received using the ultrasonic receiver that is arranged in Different Plane, compared to using list
A receiver or for the receiver in a plane, the final survey determined using the measurement result of multiple planes
Measuring result has higher precision.
