Specifically, in one embodiment, the output intent of Fetal Heart Rate of the invention as shown in figure 1, including：
Step 110, in fetal rhythm monitoring, deflection angle of the display screen relative to reference planes is obtained.
Reference planes are the planes chosen for the deflection angle information of determination display screen.Reference planes can be horizontal flat Face, perpendicular or other reference planes.
Deflection angle refers to the angle that display screen turns over relative to reference planes, that is, the plane where display screen and reference The angle formed between plane.More specifically, deflection angle is that display screen is axial along ultrasonic probe with respect to reference planes Deflection angle.
For example, it is reference planes to choose horizontal plane, when display screen is in horizontality, deflection angle is 0 degree；When aobvious When display screen is in vertical state, deflection angle is 90 degree.
When mobile or rotary ultrasonic ripple probe searches fetal rhythm position, display screen rotates relative to reference planes, display screen Current location forms deflection angle with reference planes.
The correlation data calculation that deflection angle can collect according to sensor obtains, for example, being adopted according to gravity sensor The acceleration information collected is calculated.
By obtaining deflection angle of the display screen relative to reference planes, the aobvious of display screen can be judged according to the deflection angle Show whether content is clearly visible relative to pregnant woman.
Step 130, judge in the whether default angular range of deflection angle, if it is not, step 150 is then performed, if so, then returning Step 110 is back to, and Fetal Heart Rate is exported by display screen.
Deflection angle can be the angle being rotated in the clockwise direction or the angle rotated in the counterclockwise direction. If the angle rotated in the counterclockwise direction for just, the angle being rotated in the clockwise direction be it is negative, then default angular range be Just between deflection angle and negative bias gyration, for example, default angular range is spent between 45 degree for -45.
When the deflection angle of acquisition is in default angular range, human eye is can clearly to see the content in display clearly , then in this case, pregnant woman is by checking display screen, you can knows the Fetal Heart Rate of fetus.
When the deflection angle of acquisition is not in default angular range, human eye is difficult the display content for seeing display screen, special It is not pregnant woman, when carrying out fetal rhythm monitoring, it has not been convenient to move, and fetal heart rate signal is easily influenceed in moving process, need Re-start the positioning of fetal rhythm position.Therefore, Fetal Heart Rate is exported by display screen, pregnant woman can not be made to know Fetal Heart Rate in time, In this case, then need to export Fetal Heart Rate by the way of voice broadcast.
Step 150, the Fetal Heart Rate that voice broadcast obtains.
The Fetal Heart Rate of acquisition refers to the Fetal Heart Rate shown by display screen.Turned over when display screen with respect to reference planes When deflection angle is not in default angular range, the Fetal Heart Rate that should be shown display screen is defeated in a manner of voice broadcast Go out the Fetal Heart Rate.
In order to save power supply, in voice broadcast Fetal Heart Rate, display screen can be closed.
The output intent of the Fetal Heart Rate of the present invention, by obtaining deflection angle of the display screen with respect to reference planes, and judge Whether the deflection angle is in default angular range, if it is not, the Fetal Heart Rate that then voice broadcast obtains, takes this, when display screen phase When the angle of deflection for reference planes exceedes default angular range, i.e., display screen is in sightless angle relative to pregnant woman When spending region, Fetal Heart Rate is exported by way of voice broadcast, pregnant woman is known Fetal Heart Rate in time, enables Fetal Heart Rate signal Effectively it is conveyed to pregnant woman.
In addition, the output intent of the Fetal Heart Rate of the present invention, only when display screen does not exist with respect to the deflection angle of reference planes When in default angular range, Fetal Heart Rate is just exported in a manner of voice broadcast, without sending voice always, influences pregnant woman's Mood.
In one embodiment, as shown in Fig. 2 step 110 includes：
Step 111, in fetal rhythm monitoring, display screen acceleration caused by gravity is obtained by gravity sensor.
Gravity sensor is the sensor that acceleration caused by gravity is converted to electric signal.
When display screen tilts, because the effect meeting in an inclined direction generation one by gravity is added caused by gravity Speed, the i.e. component of acceleration of weight acceleration in an inclined direction.
Display screen can be collected relative to the incline direction of reference planes because gravity causes by weight sensor Acceleration.
Step 113, deflection angle of the display screen relative to reference planes is obtained according to acceleration calculation.
Deflection angle is obtained according to acceleration and weight acceleration.
In the present embodiment, deflection angle of the display screen with respect to reference planes is obtained by gravity sensor.
In one embodiment, as shown in figure 3, the output intent of the Fetal Heart Rate of the present invention also includes：
Step 310, if deflection angle is in default angular range, between the shelter and display screen above acquisition display screen Distance.
When deflection angle is in default angular range, i.e., when display screen is in visible angular regions, pass through display Screen output Fetal Heart Rate.
But when display screen is blocked by obstructions, pregnant woman can not see the display content on display screen, therefore, obtain The distance between shelter and display screen above display screen, judge whether display screen is blocked, to determine whether to take other Mode export Fetal Heart Rate, more effectively to export Fetal Heart Rate.
The distance between shelter and display screen can detect to obtain by sensor, for example, being obtained by range sensor.
Step 330, whether the distance for judging to obtain exceedes default distance threshold, if it is not, step 350 is then performed, if so, Then it is back to step 110.
Default distance threshold refers to, when can be clearly seen the display content of display screen, between shelter and display screen Lowest distance value.For example, default distance threshold can be 1 centimetre.
When the distance of acquisition exceedes in default threshold range, then it represents that shelter does not shelter from aobvious on display screen Show content.In this case, Fetal Heart Rate is without reporting, but is shown by display screen.
When the distance of acquisition is less than default distance threshold, represent that shelter has sheltered from display screen, pregnant woman can not see Display content on clear display screen, then need to export Fetal Heart Rate by way of voice broadcast.
Step 350, the Fetal Heart Rate that voice broadcast obtains.
When the distance between shelter and display screen are less than default distance threshold, exported by way of voice broadcast Fetal Heart Rate.
In the Fetal Heart Rate that voice broadcast obtains, screen display can be closed, to save energy consumption.
In the present embodiment, when display screen relative to the deflection angle of reference planes in default angular range when, i.e., it is logical When crossing display screen output Fetal Heart Rate, when display screen is blocked by obstructions, by obtaining the shelter above display screen with showing The distance between display screen, and whether default distance threshold is exceeded according to the distance of acquisition, to judge whether to broadcast by voice The mode of report exports Fetal Heart Rate, takes this, and no matter how pregnant woman operates, and can effectively export Fetal Heart Rate, pregnant woman is worked as in time Preceding Fetal Heart Rate.
In one embodiment, as shown in figure 4, step 310 includes,
Step 311, if deflection angle is in default angular range, command range sensor sends light to the top of display screen Pulse simultaneously receives the light pulse being reflected back by shelter.
If deflection angle, in default angular range, CPU command ranges sensor sends light to the top of display screen Pulse, to start range sensor.
When the light pulse of transmission runs into the shelter above display screen, range sensor is reflected back.
Step 313, light pulse sent according to range sensor and receive time interval between the light pulse that is reflected back and The speed of light pulse, the distance between shelter and display screen is calculated.
Give one example below, illustrate the process for obtaining distance between shelter and display screen:
Time during range sensor transmission light pulse is t1, and time when receiving the light pulse being reflected back by shelter is t2, Then send light pulse and receive light pulse between time interval be t=t2-t1, the speed of light pulse is v, then shelter and The distance between display screen is d=t*v/2.
In the present embodiment, the distance between the display screen and shelter are obtained by the range sensor.
In one embodiment, as shown in figure 5, step 150 includes：
Step 151, fetal heart rate signal is obtained.
When monitoring Fetal Heart Rate, the ultrasonic probe of fetal rhythm monitoring device is placed on to the belly of pregnant woman, passes through ultrasonic wave Pop one's head in and send ultrasonic signal to the belly of pregnant woman, after ultrasonic signal reaches the fetal rhythm in her abdominal, return to ultrasound and return Ripple signal, and ultrasound echo signal is received by ultrasonic probe.Wherein, the ultrasonic signal is after motion fetal rhythm modulation Ultrasonic signal.
Ultrasound echo signal is demodulated, and it is handled, obtains fetal heart rate signal.
Step 153, extract the characteristic parameter of fetal heart rate signal and handled, obtain fetal heart rate signal intensity.
Characteristic parameter is the parameter for characterizing signal waveform form, for example, the spy such as the amplitude of signal, cycle and energy Levy parameter.
Fetal heart rate signal is fetal rhythm waveform signal, the methods of passing through Fourier transform, from fetal rhythm waveform signal extract it is a kind of or More than one characteristic parameter, by the processing to extracting characteristic parameter, calculate, obtain fetal heart rate signal intensity.
Step 155, fetal heart rate signal intensity is judged whether in the range of default intensity threshold, if so, then performing step 157, if otherwise performing 159.
When intensity threshold scope refers to that ultrasonic probe detects accurate fetal rhythm position, the strength range of fetal heart rate signal.
When fetal heart rate signal intensity is not in default intensity threshold scope, show fetal heart rate signal intensity difference, now ultrasonic wave The position of probe detection, it is not the position where fetal rhythm.
When fetal heart rate signal intensity is in the range of default intensity threshold, show that fetal heart rate signal intensity is good, now, ultrasonic wave Probe has found fetal rhythm position.
Step 157, fetal heart rate signal is handled to obtain Fetal Heart Rate, and voice broadcast Fetal Heart Rate.
Fetal heart rate signal is waveform signal, extracts the envelope signal of fetal heart rate signal, by calculate the frequency of the envelope signal and Fetal Heart Rate is obtained, or Fetal Heart Rate is obtained by extracting the frequency of fetal heart rate signal.
If fetal heart rate signal intensity belongs in default threshold range, then it represents that ultrasonic probe has found fetal rhythm position, can Carry out the report of Fetal Heart Rate.
If fetal heart rate signal intensity is not belonging in default threshold range, then it represents that the position of ultrasonic probe detection at present is simultaneously It is not the position where fetal rhythm, then without the report of Fetal Heart Rate, to avoid exporting invalid Fetal Heart Rate.
Step 159, the prompting that audio carries out fetal heart rate signal intensity is played.
When pregnant woman finds fetal rhythm, ultrasonic wave can be moved according to the prompting audio of the fetal heart rate signal intensity of current broadcasting The position of probe, takes this, and is quickly found out the location of fetus fetal rhythm.
Audio can include voice or prompt tone.Fetal Heart Rate signal intensity can be reported by playing voice, for example, reporting The voice such as " signal difference ", " lattice of signal 1 ".Prompt tone can be such as " drop drop ", " too " etc. sound.
Pregnant woman can be according to the audio prompt sent, and the position where quickly knowing current ultrasonic probe is not fetal rhythm institute Position, and mobile ultrasonic probe to find fetal rhythm position again.
The present embodiment is by judging fetal heart rate signal intensity whether in default strength range, if playing audio and entering The prompting of row fetal heart rate signal intensity, if not existing, the intensity of voice broadcast fetal heart rate signal, take this, on the one hand can improve fetal rhythm The accuracy of rate detection, on the other hand, pregnant woman is helped to be quickly found out the location of fetal rhythm.
In one embodiment, step 157 includes：Handled to obtain Fetal Heart Rate to fetal heart rate signal, and during according to first Between cycle voice broadcast Fetal Heart Rate, step 159 includes：Audio, which is played, according to the second time cycle carries out carrying for fetal heart rate signal intensity Show.Wherein, the time span in the cycle very first time was more than for the second time cycle.
When fetal heart rate signal intensity is weak, the prompting that audio carries out fetal heart rate signal intensity is played according to the second time cycle, Take this, fetal heart rate signal quality is prompted by short period frequency, be advantageous to the placement that pregnant woman quickly obtains current ultrasonic probe Whether position is accurate, and according to the position of audio prompt, in time adjustment ultrasonic probe.
When fetal heart rate signal intensity is strong, Fetal Heart Rate is reported according to the cycle very first time, takes this, is broadcast by long period frequency Report Fetal Heart Rate, on the one hand, time enough is reserved for the acquisition of Fetal Heart Rate, for example, the reserved time for calculating Fetal Heart Rate, the opposing party Face, can also avoid too frequently reporting Fetal Heart Rate makes pregnant woman sound mood agitation.
In one embodiment, step 1571 includes：
Step 1571, fetal heart rate signal is handled to obtain Fetal Heart Rate, and judges Fetal Heart Rate whether in default number range, If so, step 473 is performed, if it is not, then performing step 475.
Refer to Fetal Heart Rate number range when fetal heartbeat is normal in default number range.For example, the default numerical value Scope is 110~160bpm.
Step 1573, voice broadcast Fetal Heart Rate.
Step 1575, judge Fetal Heart Rate be in default abnormal number range, if so, then perform step 473, if it is not, Fetal Heart Rate is not reported then.
When judging Fetal Heart Rate not in default number range, in addition to the inaccurate possibility of detecting location, also may be used It can be that the Fetal Heart Rate is too high or too low, that is, be possible to fetus and exception occur, in this case, then need to report Fetal Heart Rate, so that Pregnant woman can know that abnormal situation occurs in fetus in time.
If Fetal Heart Rate is in default abnormal number range, then it represents that Fetal Heart Rate is too high or too low, and fetus is likely to occur different Often, then need to carry out voice broadcast, if Fetal Heart Rate is not in default abnormal number range, then it represents that the Fetal Heart Rate is invalid measurement Value, without practical significance, without voice broadcast.
Abnormal number range refers to corresponding Fetal Heart Rate scope during fetal abnormality, and it includes the first abnormal number range and Two abnormal number ranges.
First abnormal number range and the second abnormal number range correspond to Fetal Heart Rate it is too high or too low when number range. For example, if Fetal Heart Rate, in the default first abnormal number range, Fetal Heart Rate is too high；If Fetal Heart Rate is abnormal default second In number range, then Fetal Heart Rate is too low.
By step 471 to step 175, the degree of accuracy that Fetal Heart Rate is reported can be improved.
