Detailed description of the invention
The embodiment of the present application discloses a kind of measuring method and device of breathing rate, can use on an electronic device, described electronic equipment has ultrasonic transmitter and ultrasonic receiver, method described in the embodiment of the present application and the object of device are, utilize the breathing rate of ultrasonic measurement measured, to improve the accuracy of respiration rate measurement result.
Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
A kind of measuring method of breathing rate disclosed in the embodiment of the present application, as shown in Figure 1, comprises the following steps:
S101: produce firing order;
In the present embodiment, the generation of firing order can receive the instruction of user's input by electronic equipment and trigger, and such as, electronic equipment receives the phonetic order " respiration measurement " of user, thus produces firing order.
S102: respond firing order in the following manner: send ultrasound wave to the predetermined patterns of measured by the ultrasonic transmitter of electronic equipment in Preset Time;
Wherein, predetermined patterns is subjected to displacement with breathing, and such as, predetermined patterns can be chest, abdominal part and back etc.
S103: receive echo by the ultrasonic receiver of electronic equipment;
Usually, ultrasound wave, in the process propagated, if run into barrier can produce reflection, and forms echo.
S104: according to described ultrasound wave and echo, calculates the Changing Pattern of the displacement that predetermined patterns in preset time period occurs with breathing;
The specific implementation of this step see prior art, can repeat no more here.
S105: according to the Changing Pattern of described displacement, determines the breathing rate of measured.
Because measured is in the process of breathing, the positions such as chest can produce fluctuating and displacement, therefore, can pass through displacement rule over time, determine the breathing rate of measured.
Method described in the present embodiment, the fluctuating produced with its breathing with some position of measured is for measuring object, use ultrasound wave this for the comparatively responsive range finding instrument of distance, by measuring the change in displacement rule of predetermined patterns in presetting of measured, determine the breathing rate of measured, compared with the existing mode by breathing the acoustic measurement breathing rate produced, measured is without the need to deliberately increasing the weight of breathing, thus the situation about not being inconsistent with actual breathing state at utmost avoiding causing because measured deliberately increases the weight of breathing, ensure that measurement result is close to the real breathing state of measured.
Further, gauger even can measure under the state of measured's unaware, is therefore conducive to capturing the most natural breathing state of measured, thus improves the accuracy of measurement result.
The measuring method of the embodiment of the present application another breathing rate disclosed, compared with above-described embodiment, the method described in the present embodiment, will improve the accuracy of measurement result further, as shown in Figure 2, the present embodiment said method comprising the steps of:

The object of this step is, is filtered out by the clutter in ultrasound wave, to improve the accuracy of measurement result.Such as, if gauger's hand-hold electronic equipments measures the breathing rate of measured, very likely cause being mixed in ultrasound wave clutter because of the shake of gauger's hands, be therefore necessary to carry out filtering to ultrasound wave;
S204: send the ultrasound wave after filtering to the chest of measured in preset time period, wherein, the length of preset time period is at least greater than the time that described measured breathes preset times;
Such as, if preset times is 20, then the length of preset time period is at least greater than measured and breathed for 20 this times.Certainly, preset time period is longer, and the frequency of respiration that can measure is more, and the measurement result therefore obtained is more accurate.In actual applications, can according to the actual demand to measurement result, the length of setting preset time period.
S205: receive echo by least two ultrasonic receivers on described electronic equipment, described at least two ultrasonic receivers are arranged in the Different Plane of described electronic equipment;
Such as, as shown in Figure 3, ultrasonic receiver MIC can be 4, and one of them and ultrasonic transmitter are positioned at same plane, and other 3 lay respectively in the plane different from ultrasonic transmitter place plane.
S206: filtering is carried out to the echo received;
The object of echo being carried out to filtering is the clutter filtering in echo, to improve the accuracy of measurement result.
S207: respectively according to the combination that each echo at least two echos after after filtering and described ultrasound wave form, calculate the Changing Pattern of the displacement that described predetermined patterns occurs with breathing in described preset time period, obtain at least two reference change rules;
S208: according to described at least two reference change rules, determine the Changing Pattern of the displacement that described predetermined patterns occurs with breathing in described preset time period;
Particularly, according at least two reference change rules, a mean change rule can be obtained, as the final Changing Pattern determined.
Because the chest of measured is a three-dimensional spatiality, and ultrasound wave is propagated in the space (not considering the time) of three-dimensional, so, the ultrasonic receiver be arranged in Different Plane is used to receive echo, compared to the receptor using single receptor or be in a plane, the final measurement using the measurement result of multiple plane to determine to obtain has higher precision.
S209: according to the Changing Pattern of described displacement, determines the breathing rate of measured.
Method described in the present embodiment, receives the modes such as calculating by filtering, multiple spot multiaspect, can improve the accuracy of measurement result further.
