Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 is the flow chart of the triggering method of the electronic equipment in an embodiment. The electronic equipment performing this triggering method can be the electronic equipment that mobile phone, flat board, IPAD, digital music player, Intelligent worn device etc. are provided with physical button. All illustrate for mobile phone herein. Referring to Fig. 1, this triggering method comprises the following steps.
S110, receives the request of triggering.
The request of triggering is what to be sent by the physical button of electronic equipment. Such as, when user needs to send triggering request, it has only to press physical button. Therefore, when electronic equipment is placed and is subject to external forces together with other physics, other physics are likely to and can physical button be pressed, so that physical button sends triggering request. Triggering request is used for asking trigger electronics to perform corresponding function. According to personal like, physical button can preset and trigger request function accordingly, wishes the function that electronic equipment performs when namely pressing this button. Such as, mobile phone can be waken up by the home key pressed in mobile phone, and the power key pressing mobile phone can wake mobile phone up or perform other predefined function, as started shooting, shut down, determine, cancel, dial and the function such as music.
S120, detects the waveshape signal generated by the object contacted with electronic equipment.
Detection function requires over detecting device integrated on electronic equipment and realizes. This detecting device can be photoplethysmographic detecting device or piezoelectric membrane pulse wave detection device. The waveshape signal generated by contact object on detection region can be detected by detecting device. User needs finger is pressed against the collection carrying out waveshape signal on the detection region of detecting device. Further, detection module and receiver module are wholely set, thus substantially increasing the simplicity of user operation.
S130, it is judged that whether the waveshape signal detected is pulse wave signal.
Owing to the pulse wave signal of human body has comparatively significantly wave character, as there is main ripple and dicrotic wave and meeting certain corresponding relation between main ripple and dicrotic wave. Therefore by judging namely to can determine whether whether this waveshape signal is pulse wave signal to the wave character of the waveshape signal detected. Specifically judge process is as shown in Figure 2.Referring to Fig. 2, it is judged that the step whether waveshape signal detected is pulse wave signal includes following sub-step.
S202, the waveshape signal that acquisition testing arrives.
Waveshape signal is acquired, and the time gathering signal should be greater than or equal to 0.5 second. In other embodiment, the time gathering signal can be arranged between 1.2 seconds��2 seconds. By the restriction to acquisition time, so that it is guaranteed that the waveshape signal collected at least includes a complete wave period, to facilitate follow-up waveform to judge.
S204, it is determined that the starting point of the main ripple of waveshape signal and wave crest point.
By the waveshape signal collected is carried out period divisions substantially, so that it is determined that the starting point of the main ripple of waveshape signal and wave crest point.
S206, it is judged that whether main wave-wave peak is unsaturated.
Main wave-wave peak is unsaturated refers to that in a wave period, the wave crest point of main ripple is unique one. If its wave crest point exist multiple so that crest linearly time, then judge that main wave-wave peak is saturation, i.e. cut-off state. Judge execution S208 when main wave-wave peak is unsaturated, otherwise may determine that the waveshape signal collected is not pulse wave signal, perform S150.
S208, it is judged that whether waveshape signal exists dicrotic wave.
Dicrotic wave refers to the decent being positioned at main ripple and the amplitude waveform less than main ripple. Due in the pulse wave signal of human body, for single pulse wave cycle, pulse wave has obvious main ripple, has an obvious dicrotic wave after main ripple. Therefore by whether to having in waveshape signal, dicrotic wave is equally possible preliminary judges whether waveshape signal is pulse wave signal. When waveshape signal exists dicrotic wave, perform S210, otherwise may determine that the waveshape signal collected is not pulse wave signal, perform S150.
S210, it is determined that the trough point of the dicrotic wave of waveshape signal and wave crest point.
By the waveshape signal collected being carried out single order and second order derivation, ask for maximum and minimum, so that it is determined that go out trough point and the wave crest point of dicrotic wave.
S212, it is judged that main wave-wave peak dot to the trough point of dicrotic wave interval whether within a preset time interval.
The main wave-wave peak dot of the pulse wave signal produced due to human body is generally to the interval P4 of the trough point of dicrotic wave: 120ms < P4 < 400ms. Therefore judge that the main wave-wave peak dot of the waveshape signal collected is to whether the interval of the trough point of dicrotic wave meets this condition, if so, then performs S214, otherwise may determine that the waveshape signal collected is not pulse wave signal, perform S150.
S214, it is judged that whether the ratio of dicrotic wave amplitude and main wave amplitude is in default ratio range.
Dicrotic wave amplitude and the ratio P5 of main wave amplitude that human body produces are generally: 0 < P5 < 0.42. Therefore, it is judged that whether the dicrotic wave amplitude of the waveshape signal collected and the ratio of main wave amplitude meet this condition, if then performing S216, otherwise may determine that the waveshape signal collected is not pulse wave signal, S150 is performed.
S216, it is judged that whether the upstroke slope meansigma methods at main wave-wave peak is in default slope range.
The upstroke slope average value P 2 at the main wave-wave peak of human pulse ripple is generally: 1 < P2 < 80. Therefore judging whether the upstroke slope at the main wave-wave peak of the waveshape signal collected meets this condition, if then performing S218, otherwise may determine that the waveshape signal collected is not pulse wave signal, perform S150.
S218, it is judged that in waveshape signal, within a preset time interval whether the interval at continuous two main wave-wave peaks.
In human pulse ripple signal, the interval P3 at continuous two main wave-wave peaks is generally: 334ms < P3 < 1200ms. Therefore, judging in the waveshape signal collected, whether the interval at continuous two main wave-wave peaks meets this condition, if judging that the waveshape signal collected is pulse wave signal, performing S140, otherwise may determine that the waveshape signal collected is not pulse wave signal, perform S150. Fig. 3 represents the figure of normal human pulse ripple respectively, and Fig. 4 then represents the figure of non-human pulse wave. Wherein, A represents main ripple starting point, and B represents the wave crest point of main ripple, and C represents the trough point of dicrotic wave, and D represents the wave crest point of dicrotic wave.
In other examples, it is also possible to judge to determine whether the waveshape signal collected is pulse wave signal at least one condition in S212, S214, S216 and S218. In the present embodiment, S212, S214, S216 and S218 are all judged, it is possible to improve the accuracy judged, reduce false touch rate.
S140, trigger electronics performs to trigger request function.
After confirming that the waveshape signal that detects is pulse wave signal, perform to trigger request function accordingly according to triggering request trigger electronics, as waken up, unlock, determine, cancel, start shooting, shut down, dial and music etc.
S150, does not trigger electronic equipment.
After judging that the waveshape signal detected is not pulse wave signal, electronic equipment is not triggered, such that it is able to be prevented effectively from the false triggering owing to other object collisions cause.
The triggering method of above-mentioned electronic equipment, can't carry out immediately triggering when receiving triggering request and perform to trigger request function, but can first judge that whether the waveshape signal detected is the pulse wave signal of human body, thus only electronic equipment being triggered when the waveshape signal detected is human body pulse wave signal judging, greatly reduce owing to the false touch situation of electronic equipment is occurred by other objects, reduce the false touch rate of electronic equipment, can reduce because of the false touch abrasion to electronic equipment simultaneously, improve the life-span of electronic equipment.
