Detailed Description

The embodiment of the invention provides a control method of a reversible intelligent watch, the reversible intelligent watch and a storage medium, which are used for avoiding the situation that when a user uses the reversible intelligent watch, a PPG (photo graphic processing) module on the reversible intelligent watch damages eyes of the user, and reducing the power consumption of the reversible intelligent watch.

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. The embodiments based on the present invention should fall into the protection scope of the present invention.

It can be understood that the reversible smart watch according to the embodiment of the present invention may be worn directly on the wrist of the user or on the ankle of the user. The smart watch that can overturn is not only a hardware equipment, more can realize powerful intelligent function through software support and data interaction, high in the clouds interaction, for example: the intelligent watch has a calculation function, a positioning function and an alarm function, and can be connected with other turnable intelligent watches and various terminals.

It should be noted that, as shown in fig. 1a, which is a schematic diagram of an embodiment of the reversible smart watch in an embodiment of the present invention, the reversible smart watch may include a support 101, a host 102, and a rotation element 103, where the support 101 is connected to the host 102 and the rotation element 103, the host 102 is capable of rotating relative to the support 101, and the host 102 may be provided with a photoplethysmography PPG module 1021.

The PPG module 1021 may include three light emitters, namely a first light emitter, a second light emitter, and a third light emitter. The first light emitter is used for emitting infrared light which is invisible, the infrared light is used for detecting whether an object to be detected exists in front of the reversible intelligent watch or not, and detecting whether the object to be detected is a living body or not under the condition that the object to be detected exists; the second light emitter is used for emitting red light signals, the third light emitter is used for emitting green light signals, the red light and the green light flash in real time, and the red light signals and the green light signals can detect the heart rate of the living body under the condition that the infrared light determines that the object to be detected is the living body.

It should be noted that the first surface 1022 of the host 102 is provided with the protruding portion 1023, the first surface 1022 is a surface deviating from the display surface of the host 102, and the display surface is a surface where the display screen is located;

further, PPG module 1021 is disposed on second side 10231 of protrusion 1023, where second side 10231 of protrusion 1023 faces away from first side 1022 of host 102;

furthermore, the support 101 is provided with a through hole 1011 matching with the protrusion 1023, so that when the host 102 rotates relative to the support 101 and the host 102 is attached to the support 101, the protrusion 1023 can be accommodated in the through hole 1011, that is, when the rotation state of the host 102 relative to the support 101 is a closed state, the PPG module 1021 can be accommodated in the through hole 1011.

Therefore, when the user wears the reversible watch on the arm, the PPG module 1021 in the reversible watch can be attached to the skin of the arm of the user, and the light emitter in the PPG module 1021 can emit light signals to the skin of the user, so that the functions of living body detection/heart rate detection and the like are realized. . Of course, the reversible watch may be worn at other positions of the user, and is not limited herein.

Optionally, the reversible smart watch may further include a hall sensor 104.

The hall sensor 104 is used for acquiring a potential interruption result to detect a rotation state of the host 102 relative to the bracket 101.

It is understood that the rotation state of the main body 102 relative to the stand 101 may be a closed state or a non-closed state. The rotation state of the host 102 relative to the support 101 may be detected by a hall sensor, and may be determined according to an angle between the host 102 and the support 101, or according to a distance between a center point of the host 102 and a center point of the support 101, which is not described in detail herein.

When the rotation state of the host 102 relative to the support 101 is a non-closed state, if the PPG module 1021 is in a working state, the light emitter in the PPG module 1021 emits a light signal. A user, especially a child, may look at the light emitter of the PPG module 1021 all the time due to curiosity, which may cause the light signal emitted by the light emitter to damage the eyes of the child. And when the rotation state of the host 102 relative to the support 101 is a non-closed state, the PPG module cannot contact with the skin of a human body, and the optical signal emitted by the optical emitter cannot be used for performing living body detection or heart rate detection, etc., so that the power consumption loss of the flip watch can be caused by the constant start.

It is understood that in the reversible smart watch shown in fig. 1a, the host 102 is in a closed state with respect to the rotation of the stand 101.

Optionally, as shown in fig. 1b, the turning state of the host of the reversible smart watch relative to the stand is a closed state according to an embodiment of the present invention.

In the following, the technical solution of the present invention is further described in an embodiment, as shown in fig. 2, which is a schematic view of an embodiment of a method for controlling a reversible smart watch according to an embodiment of the present invention, where the reversible smart watch includes a support and a host, the host can rotate relative to the support, and a photoplethysmography PPG module is disposed on the host, and the method may include:

201. and detecting the rotating state of the host relative to the bracket.

Optionally, the reversible smart watch may detect the rotation state of the host with respect to the support, which may include, but is not limited to, the following implementation manners:

implementation mode 1: the reversible intelligent watch obtains a potential interruption result through the Hall sensor; the turnable intelligent watch obtains the rotation state of the host relative to the support according to the potential interruption result.

It should be noted that the hall sensor is a magnetic field sensor manufactured according to the hall effect. The hall effect is a phenomenon of magnetoelectric effect, which was discovered by hall in 1879 when studying the conductive mechanism of metals. Later, semiconductors, conductive fluids, etc. have been found to have hall effect, which is much stronger than that of metals, so that various hall elements, including hall sensors, made by using hall effect are widely used in industrial automation technology, detection technology, information processing, etc.

It is understood that the hall sensor can acquire a potential triggering result and also can acquire a potential interruption result. The potential trigger result can be triggered by a rising edge or a falling edge; the potential interruption result may be a rising edge triggered interruption or a falling edge triggered interruption, and is not particularly limited herein. The rising edge trigger refers to that the potential is changed from low to high to trigger output change; the rising edge triggered interruption refers to interruption of the process that the potential is changed from low to high to trigger output change; the falling edge trigger refers to that the potential is changed from high to low to trigger output change; the falling edge triggered interruption refers to interruption of the process that the potential changes from high to low to trigger output change.

The reversible intelligent watch obtains a potential interruption result through the Hall sensor, and can obtain the rotation state of the host relative to the support according to the potential interruption result in time.

Optionally, the reversible smart watch obtains a rotation state of the host with respect to the stand according to the potential interruption result, and may include: when the potential interruption result is that the interruption is triggered by the rising edge, the turnable intelligent watch determines that the rotation state of the host relative to the bracket is a non-closed state; when the potential interruption result is that the falling edge triggers interruption, the turnable intelligent watch determines that the rotation state of the host machine relative to the support is a closed state.

Implementation mode 2: the turnable intelligent watch obtains an angle between the host and the bracket; and detecting the rotation state of the host relative to the bracket according to the angle.

It should be noted that the reversible smart watch can obtain the distance between the center point of the host and the rotating member, the distance between the center point of the support and the rotating member, and the distance between the center point of the host and the center point of the support; the intelligent wrist-watch that should overturn according to these three distances and collude the pythagorean theorem, can obtain the angle between this host computer and this support.

It will be appreciated that the host center point is determined from the shape of the host, and similarly, the stent center point is determined from the shape of the stent. In particular, the shape of the host generally conforms to the shape of the stent.

For example: if the shape of the host is circular, the center point of the host can be the center of the circle; if the host is rectangular, the center point of the host can be the center of the rectangle, namely the intersection point of the diagonals; if the shape of the host computer is other irregular shapes, the center point of the host computer may be the center of gravity or the center of mass of the other irregular shapes, which is not limited herein.

Optionally, the intelligent wrist-watch that can overturn detects the rotation state of this host computer relative this support according to this angle, can include: when the angle is smaller than a preset angle threshold value, determining that the rotation state of the host relative to the bracket is a closed state; and when the angle is larger than or equal to the preset angle threshold value, determining that the rotating state relative to the bracket is a non-closing state.

It should be noted that the preset angle threshold may be obtained by the reversible smart watch in a large amount of first experimental data, that is, the preset angle threshold may be set before the reversible smart watch leaves the factory.

For example, assume that the predetermined angle threshold is 30 degrees (abbreviated: °). If the turnable intelligent watch obtains that the angle between the host and the support is 12 degrees, and the 12 degrees are smaller than 30 degrees, the turnable intelligent watch can determine that the host is in a closed state relative to the rotation state of the support; if the intelligent watch capable of overturning obtains that the angle between the host and the support is 63 degrees, and the 63 degrees are larger than 30 degrees, the intelligent watch capable of overturning can determine that the rotating state relative to the support is a non-closed state.

Implementation mode 3: the turnover intelligent watch obtains a first distance between the host and the support through a distance sensor; and detecting the rotating state of the host relative to the bracket according to the first distance.

Wherein, the distance sensor is arranged on the host. In fact, the first distance that the reversible smartwatch acquires via the distance sensor may be a distance between a host center point and a support center point.

Optionally, when the first distance is smaller than a first preset distance threshold, the reversible smart watch determines that the rotation state of the host relative to the bracket is a closed state; and when the distance is greater than or equal to the first preset distance threshold, determining that the rotating state of the host relative to the bracket is a non-closing state.

It should be noted that the first preset distance threshold may be obtained by the reversible smart watch in a large amount of second experimental data, that is, the first preset distance threshold may be set before the reversible smart watch leaves the factory.

For example, assume that the predetermined distance threshold is 1 centimeter (cm). If the reversible intelligent watch obtains that the first distance between the host and the support is 0.2cm through the distance sensor, and the 0.2cm is smaller than 1cm, the reversible intelligent watch can determine that the host is in a closed state relative to the support in a rotating state; if the turnable intelligent watch obtains that the first distance between the host and the support is 1.5cm through the distance sensor, and the 1.5cm is larger than 1cm, the turnable intelligent watch can determine that the host is in a non-closed state relative to the rotation state of the support.

It can be understood that the implementation manners 1-3 in step 101 may be combined with each other to form a new implementation manner, and the new implementation manner is also within the protection scope of the present invention, and will not be described herein in detail

Optionally, after step 101, the method may further include: the smart watch can turn over to output first prompt information.

Wherein, this first prompt information is used for the rotation state of the host computer relative support that the suggestion user should overturn in the intelligent wrist-watch.

Optionally, the reversible smart watch outputs the first prompt message, which may include but is not limited to the following implementation manners:

implementation mode 1: the intelligent watch can turn over and output first prompt information in a voice mode.

It should be noted that the voice may be set before the smart watch leaves the factory, or may be set by the user according to the preference of the user, which is not specifically limited herein.

Implementation mode 2: the intelligent wrist-watch that can overturn outputs first suggestion information in the form of flashing light.

It should be noted that the flashing light may flash with a monochromatic light, or alternatively flash with a colored light, and is not limited herein.

The following are exemplary: the single-color light twinkling can indicate that the rotating state of the host computer relative to the bracket is a closed state; the alternate flashing of the colored lights can indicate that the main machine is in a non-closed state relative to the rotating state of the bracket.

Implementation mode 3: the intelligent watch can turn over to output first prompt information in a vibration mode.

The vibration may be intermittent vibration or continuous vibration, and is not particularly limited herein.

The following are exemplary: the intermittent vibration can indicate that the rotation state of the main machine relative to the bracket is a closed state; the continuous vibration can indicate that the rotation state of the main machine relative to the bracket is a non-closed state.

Implementation mode 4: the intelligent wrist-watch that can overturn sends first prompt information to the terminal equipment that should overturn the intelligent wrist-watch relevance.

It should be noted that, in implementation 4, a user using a terminal device can conveniently master the flip state of the smart watch in real time, so as to take corresponding measures.

It can be understood that the voice form, the flashing light form and the vibration form are convenient for a user to intuitively know the rotating state of the host in the reversible intelligent watch relative to the support. In particular, the implementation manners 1 to 4 may be combined with each other to form new implementation manners, which are also within the protection scope of the present invention and will not be described in detail herein.

202. And when the rotation state of the host relative to the support is a non-closing state, the PPG module is closed.

It should be noted that the PPG module has a PPG function.

The PPG function is an infrared nondestructive detection technology for detecting blood volume change in living tissues by using a photoelectric conversion technology. When a light beam of a certain wavelength is applied to the surface of the finger tip skin, each heartbeat, the contraction and expansion of the blood vessels affects the transmission of light (e.g., light passing through the fingertip in transmission PPG) or the reflection of light (e.g., light from the vicinity of the surface of the wrist in reflection PPG). When light is transmitted through the skin tissue and then reflected to the light sensor, there is some attenuation of the light. The absorption of light by the tissues like muscles, bones, veins and other connections is substantially constant (provided that there is no substantial movement of the measurement site), but the arteries will be different and naturally also vary due to the pulsation of the blood in the arteries. When the optical sensor converts an optical signal into an electrical signal, the absorption of light by the artery is changed, but the absorption of light by other tissues is basically unchanged, and the obtained signal can be divided into a Direct Current (DC) signal and an Alternating Current (AC) signal. The reversible intelligent watch can reflect the characteristic of blood flow according to the AC signal.

It is understood that, in the process of turning off the PPG module by the flip smart watch, instead of turning off the second light emitter and the third light emitter of the PPG module at the same time, the second light emitter may be turned off first and then the third light emitter may be turned off, or vice versa.

In the embodiment of the invention, the rotation state of the host relative to the bracket is detected; and when the rotation state of the main machine relative to the support is a non-closed state, the PPG module is closed. The intelligent watch can be turned over to judge the rotation state of the host of the intelligent watch relative to the support; and when the rotation state is a non-closing state, closing the PPG module. The method can avoid the situation that the PPG module on the reversible intelligent watch damages the eyes of the user when the user uses the reversible intelligent watch, and can reduce the power consumption of the reversible intelligent watch.

As shown in fig. 3, which is a schematic view of another embodiment of a method for controlling a reversible smart watch according to an embodiment of the present invention, the reversible smart watch includes a support and a host, the host can rotate relative to the support, and a photoplethysmography PPG module is disposed on the host, and the method may include:

301. and detecting the rotating state of the host relative to the bracket.

302. And when the rotation state of the host relative to the support is a non-closing state, the PPG module is closed.

It should be noted that steps 301 to 302 are similar to steps 201 to 202 shown in fig. 2 in this embodiment, and are not described again here.

303. When the rotation state of the main machine relative to the support is a closed state, the PPG module is started and is controlled to emit light signals.

In some embodiments, when the reversible watch is turned on, the PPG module is automatically triggered to turn on, providing convenience for the module to detect the living body/heart rate.

Besides, when the PPG module is in a working state, if the rotation state of the host of the reversible watch relative to the support is detected to be a non-closed state, the reversible watch can close the PPG module, so that the eyes of a user can be protected, and the power consumption of the reversible watch can be saved, so that the service life of the reversible watch can be prolonged.

It is understood that when the rotation state of the host computer relative to the support is a closed state, the PPG module may be in an operating state all the time, that is, the first light emitter in the PPG module continuously emits infrared light signals, and the second light emitter continuously emits red light signals and/or the third light emitter continuously emits green light signals.

However, if the rotation state of the host relative to the support is a closed state, and the user cannot see the optical signal emitted by the optical emitter in the PPG module, the optical signal cannot be generated to cause a certain damage to the eyes of the user, so that the flip watch can start the PPG module and control the PPG module to emit the optical signal when determining that the rotation state of the host relative to the support is the closed state, so as to detect whether an object to be detected exists in front of the flip watch, and detect whether the object to be detected is a living body when determining that the object to be detected exists.

Optionally, the smart watch that can overturn controls this PPG module to emit optical signals, may include: controlling a first light emitter of the PPG module to emit an infrared light signal; if the reversible intelligent watch detects that the object to be detected has pulse waves according to the reflected signals of the infrared light signals acquired by the PPG module, the object to be detected is determined as a living body.

The presence of the pulse wave is a basis for determining the object to be measured as a living body.

Optionally, if the reversible smart watch detects that the object to be detected has a pulse wave according to the reflected signal of the infrared light signal acquired by the PPG module, the object to be detected is determined to be a living body, which may include: the reversible intelligent watch acquires a reflection signal of the infrared light signal according to the PPG module; when the signal value of the reflected signal is greater than a preset signal threshold value, the reversible watch determines that an object to be detected exists; and the reversible watch detects that the object to be detected has pulse waves according to the reflection signals, and then determines the object to be detected as a living body.

It should be noted that, after the reflection signal of this infrared light signal that the PPG module was gathered, should can overturn the wrist-watch through the magnitude of signal value and predetermined signal threshold value of this comparison reflection signal to judge whether there is the sheltering object in this wrist-watch the place ahead of should overturning, at this moment, should shelter from the object and be the object that awaits measuring, and this object that awaits measuring can be the living body, also can be non-living body, does not do specific limit here.

If the signal value of the reflection signal is larger than a preset signal threshold value, the reversible watch can determine that a shielding object exists in front; if the signal value is less than or equal to the predetermined signal threshold, the reversible watch may determine that an obstructing object is not present in front.

It can be understood that the preset signal threshold may be selected by collecting the wearable device in a large amount of third experimental data, that is, the preset signal threshold is set before the wearable device leaves the factory, and details are not described here.

Optionally, the method may further include: and when the signal value is less than or equal to the preset signal threshold value, the reversible watch closes the PPG module.

It is understood that, since the non-living body is not present with a pulse wave, when the signal value is less than or equal to the preset signal threshold, the reversible watch may turn off the PPG module, so as to reduce power consumption of the reversible watch.

Optionally, the method may further include: when the signal value is smaller than or equal to the preset signal threshold value, the reversible watch outputs second prompt information and receives a first instruction input by a user, wherein the second prompt information is used for prompting that no object to be detected exists in front of the user; the wearable device is controlled to enter a standby state or a shutdown state according to the first instruction.

It can be understood that the first instruction is used to control the wearable device to enter a standby state or a power-off state, the first instruction may be a voice instruction, and may be a key instruction, and the key instruction may be an entity key instruction or a virtual key instruction, which is not limited specifically herein.

Optionally, the reversible watch detects that the object to be measured has a pulse wave according to the reflection signal, and then determines the object to be measured as a living body, which may include: the reversible watch acquires a second distance between the reversible watch and the object to be detected; when the second distance of the reversible watch is within the second preset distance range, the pulse wave of the object to be detected is detected according to the reflection signal, and then the object to be detected is determined as a living body.

It should be noted that the explanation of the second preset distance threshold in step 303 is similar to the explanation of the first preset distance threshold in step 101, and details are not described here.

It can be understood that there may be a plurality of objects that await measuring in the place ahead of the intelligent wrist-watch that can overturn, if should can overturn the intelligent wrist-watch and confirm the object that awaits measuring in certain extent, then, should overturn the intelligent wrist-watch and can detect the pulse wave in comparatively accurate object that awaits measuring to reduce the false retrieval rate.

In the embodiment of the invention, the rotation state of the host relative to the bracket is detected; when the rotation state of the host relative to the support is a non-closed state, closing the PPG module; when the rotation state of the host relative to the support is a closed state, the PPG module is started and is controlled to emit light signals. The intelligent watch can be turned over to judge the rotation state of the host of the intelligent watch relative to the support; closing the PPG module under the condition that the rotation state is a non-closed state; and in the case that the rotation state is a closed state, activating the PPG module and controlling the PPG module to emit a light signal. The method can avoid the condition that the PPG module on the reversible intelligent watch damages the eyes of the user when the user uses the reversible intelligent watch, can reduce the power consumption of the reversible intelligent watch, and can determine the object to be detected as the living body through the PPG module.

As shown in fig. 4, which is a schematic view of another embodiment of a method for controlling a reversible smart watch according to an embodiment of the present invention, the reversible smart watch includes a support and a host, the host can rotate relative to the support, and a photoplethysmography PPG module is disposed on the host, and the method may include:

401. the rotating state of the main machine relative to the bracket is detected.

402. And when the rotation state of the host relative to the support is a non-closing state, the PPG module is closed.

403. When the rotation state of the host relative to the support is a closed state, the PPG module is started and is controlled to emit light signals.

It should be noted that steps 401 to 403 are similar to steps 301 to 303 shown in fig. 3 in this embodiment, and are not described again here.

404. Controlling a second light emitter of the PPG module to emit a red light signal and/or a third light emitter to emit a green light signal to detect the heart rate of the living subject.

It can be understood that the intelligence wrist-watch that can overturn can adopt the green glow to detect the rhythm of the heart of living body usually, and the reason that this intelligence wrist-watch that can overturn adopts the green glow to detect the rhythm of the heart is that the signal that the intelligence wrist-watch that can overturn obtained with the green glow can be than the signal amplitude of change that obtains with ruddiness is big, and the ability that influences with the anti ambient light of green glow is better than the ability that influences with the anti ambient light of red light. So, the intelligence that can overturn wrist-watch adopts the green glow to detect the signal to noise ratio of rhythm of the heart than adopting the red light to detect the signal to noise ratio of rhythm of the heart high, and the signal to noise ratio is higher, and the external world is less to the interference that can overturn intelligence wrist-watch detects the rhythm of the heart, and the rhythm of the heart that should overturn intelligence wrist-watch detected is more accurate.

Optionally, the reversible smart watch controls the second light emitter of the PPG module to emit a red light signal, and/or the third light emitter to emit a green light signal, to detect the heart rate of the living subject, which may include but is not limited to the following implementations:

implementation mode 1: after waiting for a preset duration, the reversible smart watch controls the second light emitter of the PPG module to emit a red light signal, and/or the third light emitter emits a green light signal to detect the heart rate of the living body.

It should be noted that, when the reversible smart watch determines the object to be measured as a living body, the reversible smart watch may detect the heart rate of the living body after a period of time. Namely, the reversible intelligent watch has a certain time delay function.

Implementation mode 2: the second light emitter of this PPG module of smart watch direct control that can overturn sends red light signal to according to the red light reflection signal detects the heart rate of this live body periodically, and/or, the third light emitter of this PPG module of smart watch direct control that should overturn sends green light signal, with according to the green light reflection signal detects the heart rate of this live body periodically.

It should be noted that, when the smart watch that can overturn determined the object to be measured as the living body, this smart watch that can overturn can detect the heart rate of this living body periodically.

Illustratively, the reversible smart watch controls the second light emitter of the PPG module to emit a red light signal, detecting the heart rate of the living subject at 17 pm on a wednesday.

Implementation mode 3: after waiting for preset duration, the second light emitter of the smart watch capable of overturning controls the PPG module to emit red light signals so as to periodically detect the heart rate of the living body according to the red light reflection signals, and/or the third light emitter of the smart watch capable of overturning controls the PPG module to emit green light signals so as to periodically detect the heart rate of the living body according to the green light reflection signals.

Implementation mode 4: the second light emitter of this PPG module of smart watch control that can overturn sends red light signal, and/or, the green light signal of third light emitter transmission detects the heart rate of this live body with first frequency.

It will be appreciated that the first frequency lies within a first predetermined frequency range. The first preset frequency range may be composed of a first preset frequency threshold and a second preset frequency threshold, and the first preset frequency threshold is smaller than the second preset frequency threshold.

It should be noted that, the condition that the value of this first frequency need satisfy can overturn the intelligent wrist-watch and can detect the rhythm of the heart on the living body.

For example, assuming that the first predetermined frequency range is (20hz, 30hz) and the third frequency is 25Hz and is within (20hz, 10hz), the reversible smart watch controls the second light emitter of the PPG module to emit a red light signal, and detects the heart rate of the living body at the frequency of 25 Hz.

Optionally, after step 404, the method may further include, but is not limited to, the following implementation:

implementation mode 1: when this rhythm of the heart is located preset rhythm of the heart within range, will record and save with this rhythm of the heart.

The preset heart rate range is an interval formed by a first preset heart rate threshold value and a second preset heart rate threshold value, the first preset heart rate threshold value is smaller than the second preset heart rate threshold value, and the preset heart rate range is generally set to (60 times/minute and 100 times/minute).

Implementation mode 2: and when the heart rate is out of the preset heart rate range, outputting third prompt information.

Wherein, this third prompt information is the intelligent wrist-watch that can overturn according to this rhythm of the heart, for the relevant suggestion that the user provided.

Optionally, when this rhythm of the heart is located this and predetermines the rhythm of the heart scope outward, the intelligent wrist-watch that can overturn outputs third prompt message, can include: when the heart rate is less than or equal to a first preset heart rate threshold value, outputting first sub-prompt information; and outputting second sub-prompt information when the heart rate is greater than or equal to a second preset heart rate threshold value.

It can be understood that, when the heart rate is less than or equal to the first preset heart rate threshold, the reversible smart watch may determine that the living body is in the tachycardia state, and the output first sub-prompt information may remind the user to detect the thyroid function of the user; when this rhythm of heart is more than or equal to the second and predetermines the rhythm of heart threshold value, this intelligent wrist-watch that can overturn can judge that this live body is in bradycardia state, and the sub-tip information of second of output can be the reason that the suggestion user detected this live body rhythm of heart and hang down to take corresponding measure.

There are three reasons for the low heart rate: the first is vagal hyperfunction, which, when excited, releases a substance called "acetylcholine" at the distal ends of the vagus nerve, causing a hypopnea; the second is sick sinus syndrome, which is a sick heart manifestation and can be the heart rate hypo caused by coronary heart disease, cardiomyopathy and other diseases; the third is a severe atrioventricular block that causes a too slow heartbeat, thereby causing a too low heart rate.

In the embodiment of the invention, the rotation state of the host relative to the bracket is detected; when the rotation state of the host relative to the support is a non-closed state, closing the PPG module; when the rotation state of the main machine relative to the support is a closed state, the PPG module is started and is controlled to emit light signals. The intelligent watch can be turned over to judge the rotation state of the host of the intelligent watch relative to the bracket; closing the PPG module under the condition that the rotation state is a non-closed state; and in the case that the rotation state is a closed state, activating the PPG module and controlling the PPG module to emit a light signal. The method can avoid the situation that the PPG module on the reversible intelligent watch damages the eyes of the user when the user uses the reversible intelligent watch, can reduce the power consumption of the reversible intelligent watch, and can detect the heart rate of the living body through the PPG module under the situation that the object to be detected is the living body.

In general, RF circuit 610 includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 610 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), general Packet Radio Service (GPRS), code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), long Term Evolution (LTE), email, short Messaging Service (SMS), etc.

The memory 620 may be used to store software programs and modules, and the processor 680 may execute various functional applications and data processing of the reversible smart watch by executing the software programs and modules stored in the memory 620.

Further, the memory 620 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 630 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the reversible smart watch. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also referred to as a touch screen, may collect touch operations of a user (e.g., operations of the user on the touch panel 631 or near the touch panel 631 by using any suitable object or accessory such as a finger or a stylus) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 631 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 680, and can receive and execute commands sent by the processor 680. In addition, the touch panel 631 may be implemented using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 630 may include other input devices 632 in addition to the touch panel 631. In particular, other input devices 632 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

Further, the touch panel 631 may cover the display panel 641, and when the touch panel 631 detects a touch operation thereon or nearby, the touch operation is transmitted to the processor 680 to determine the type of the touch event, and then the processor 680 provides a corresponding visual output on the display panel 641 according to the type of the touch event. Although in fig. 6, the touch panel 631 and the display panel 641 are two separate components to implement the input and output functions of the reversible smart watch, in some embodiments, the touch panel 631 and the display panel 641 may be integrated to implement the input and output functions of the reversible smart watch.

WiFi belongs to short distance wireless transmission technology, and the smart watch that can overturn can help the user to receive and dispatch email, browse the webpage and visit streaming media etc. through WiFi module 670, and it provides wireless broadband internet access for the user. Although fig. 6 shows a WiFi module 670, it is understood that it is not an essential component of the reversible smartwatch and may be omitted entirely as needed within the scope that does not alter the essence of the invention.
