Referring to fig. 1, fig. 1 is a flowchart of an ECG data acquisition method provided in an embodiment of the present application, where an execution subject of the embodiment may be a processor of a wrist-worn device, and the steps implemented when the processor calls a computer program in a memory include:

s101: it is determined whether a body composition detection instruction input by the user is received.

The body composition detection instruction is used for detecting impedance data of a user, the user can input the body composition detection instruction through a key or a touch component of the wrist-worn device, and the user can also input the body composition detection instruction through other terminals (such as a mobile phone or a remote controller).

S102: and judging whether the rotating piece rotates to a preset position according to data collected by the position detection sensor.

The embodiment can acquire data collected by the position detection sensor according to a preset period, and then judge whether the rotating member rotates to a preset position according to the data collected by the position detection sensor. If the rotating piece rotates to a preset position, it indicates that the wrist-worn equipment needs to acquire physical sign data; if the rotating member does not rotate to the preset position, the processor can enter a sleep state and can also start other functions, such as music playing, sleep detection, motion monitoring and the like.

S103: if the body composition detection instruction input by the user is not received and the rotating piece rotates to the preset position, the electronic switch is controlled to communicate the conductive electrode with the ECG sensor, and the ECG sensor is used for collecting ECG data through the conductive electrode.

If the body composition detection instruction input by the user is not received and the rotating member rotates to the preset position, which indicates that the user may have cardiac discomfort at the moment, the ECG data acquisition process can be directly entered at the moment. Specifically, the processor may control the electronic switch to communicate the conductive electrode with the ECG sensor, thereby acquiring ECG data via the conductive electrode using the ECG sensor. The present embodiment may also present an ECG sensor enabling operation, the enabled ECG sensor acquiring corresponding ECG data through the conductive electrodes. In particular, the user may place the wrist and fingers on the conductive electrodes so that the ECG sensor acquires the user's ECG data through the conductive electrodes.

The present embodiment utilizes the data collected by the position detection sensor to determine the rotation position of the rotating member, and when the rotating member rotates to the preset position, it indicates that the user has a need to collect the physical sign data. The embodiment can also judge whether a body composition detection instruction input by a user is received, if the body composition detection instruction input by the user is not received, and the rotating piece rotates to the preset position, the conductive electrode is controlled to be communicated with the ECG sensor, and the ECG sensor is used for collecting ECG data through the conductive electrode. When the heart of the user is uncomfortable, the ECG data can be acquired by adjusting the rotating piece, and the convenience of the ECG data acquisition process can be improved.

By way of further introduction to the above embodiments, the processor may further implement the following operations: if a body composition detection instruction input by a user is received and the rotating piece rotates to a preset position, the electronic switch is controlled to communicate the conductive electrode with the bio-impedance sensor, and the bio-impedance sensor is used for acquiring impedance data through the conductive electrode. The present embodiment may also have an operation of enabling the bio-impedance sensor, and the enabled bio-impedance sensor may collect corresponding impedance data through the conductive electrode. In particular, the user may place the wrist and fingers on the conductive electrodes so that the bio-impedance sensor collects impedance data of the user through the conductive electrodes.

In this embodiment, the sequence of the two actions of "receiving a body composition detection instruction" and "rotating the rotating member to the preset position" in the impedance data acquisition process is not limited. Specifically, the present embodiment may preset a first delay time, if the action of "the rotating member rotates to the preset position" is executed first, it may be determined whether a body composition detection instruction is received within the first delay time after the rotating member rotates to the preset position, if so, an operation flow of "controlling the electronic switch to communicate the conductive electrode with the bioimpedance sensor, and acquiring impedance data through the conductive electrode" is performed, otherwise, an operation flow of "controlling the electronic switch to communicate the conductive electrode with the ECG sensor, and acquiring ECG data through the conductive electrode" is performed. The embodiment can also preset second delay time, if the action of receiving the body composition detection instruction is executed first, whether the rotating member rotates to the preset position within the second delay time after the body composition detection instruction is received can be judged, if yes, the operation flow of controlling the electronic switch to communicate the conductive electrode with the biological impedance sensor and acquiring impedance data through the conductive electrode by using the biological impedance sensor is started, and if not, the user is reminded to rotate the rotating member or the received body composition detection instruction is judged to be an invalid instruction.

Further, the ECG sensor and the bio-impedance sensor may multiplex the conductive electrodes, thereby reducing the number of conductive electrodes in the wrist-worn device. For example, the conductive electrodes include at least one multiplexed electrode; when the rotating piece rotates to a preset position, the multiplexing electrode is connected with the electronic switch.

On the basis of using the multiplexing electrode, the processor can control the electronic switch to communicate the multiplexing electrode with the ECG sensor; the processor may also control the electronic switch to communicate the multiplexed electrodes with the bio-impedance sensor.

Taking the example that an ECG sensor needs 3 conductive electrodes to acquire ECG data and a bioimpedance sensor needs 4 conductive electrodes to acquire impedance data, the conductive electrodes include a first conductive electrode, a second conductive electrode, a third conductive electrode and a fourth conductive electrode.

Referring to fig. 2, fig. 2 is a schematic diagram of a first electrode multiplexing circuit provided in the embodiment of the present application, in which the first conductive electrode, the second conductive electrode, and the third conductive electrode are all multiplexing electrodes, and when the rotating member rotates to a preset position, the fourth conductive electrode is communicated with the bio-impedance sensor. The ECG sensor may acquire ECG data using the first, second, and third conductive electrodes, and the bioimpedance sensor may acquire impedance data using the first, second, third, and fourth conductive electrodes.

Referring to fig. 3, fig. 3 is a schematic diagram of a second electrode multiplexing circuit provided in the embodiment of the present application, in which the first conductive electrode, the second conductive electrode, the third conductive electrode, and the fourth electrode are all multiplexing electrodes. The ECG sensor may acquire ECG data using any three of the first, second, third and fourth conductive electrodes, and the bioimpedance sensor may acquire impedance data using the first, second, third and fourth conductive electrodes. As a possible implementation, in the manner shown in fig. 3, if it is required to control the conductive electrode to communicate with the ECG sensor, the electronic switch may control the first conductive electrode, the second conductive electrode and the third conductive electrode to communicate with the ECG sensor respectively; if the conductive electrode needs to be controlled to be communicated with the biological impedance sensor, the electronic switch can control the first conductive electrode, the second conductive electrode and the third conductive electrode to be respectively communicated with the biological impedance sensor. Above-mentioned wrist wears equipment and still includes the mainboard, and the mainboard is provided with the electrically conductive elastic component of being connected with electronic switch to and the electrically conductive elastic component of second of being connected with biological impedance sensor, the casing that wrist wore equipment is provided with first trompil and second trompil. When the rotating member rotates to a preset position, the first conductive elastic member penetrates through the first opening to be connected with the third conductive electrode, and the second conductive elastic member penetrates through the second opening to be connected with the fourth conductive electrode. By the above mode, the physical sign data sensor can acquire data only through the conductive electrode when the rotating piece rotates to the preset position, and the detection reliability is improved. The first conductive elastic element and the second conductive elastic element can be conductive elastic sheets or conductive elastic thimbles.

In the electrode multiplexing circuit shown in fig. 2 and 3, the processor can send a control signal to the electronic switch according to the rotation position of the rotating member, so that the electronic switch switches the normally open contact no (normal open) and the normally closed contact nc (normal close), and further adjusts the communication between the conductive electrode and the ECG sensor and the bioimpedance sensor. Further, the first conductive electrode and the second conductive electrode may be disposed at a wearing contact portion of the wrist-worn device, such as a lower surface of a lower shell of the wrist-worn device; the third conductive electrode and the fourth conductive electrode may be disposed at non-wearable contact portions of the wrist-worn device, such as a rotating element, a key, a wrist band, an upper surface of the upper case, a lower surface of the upper case, and the like. The wearing contact part is a part of the wrist-worn device contacting with the body of the user when the wrist-worn device is worn, and the non-wearing contact part is a part of the wrist-worn device not contacting with the body of the user when the wrist-worn device is worn.

As a further introduction to the corresponding embodiment of fig. 1, the steps implemented when the processor invokes the computer program in the memory further comprise: if a user-defined instruction input by a user is received, updating target operation corresponding to a preset position according to the user-defined instruction; the target operation is an operation executed when the body composition detection instruction input by the user is not received and the rotating member rotates to the preset position.

Through the mode, the operation can be realized when the rotating piece is rotated to the preset position by user definition. For example, if the user updates the target operation corresponding to the preset position to the ECG data acquisition operation through the custom instruction, and if the body composition detection instruction input by the user is not received and the rotating member rotates to the preset position, the executed operations include: the control electronics switch communicates the conductive electrode with the ECG sensor and acquires ECG data via the conductive electrode using the ECG sensor. If the user updates the target operation corresponding to the preset position into the impedance data acquisition operation through the user-defined instruction, if the rotating member rotates to the preset position, the executed operation comprises the following steps: the control electronic switch communicates the conductive electrode with the bioimpedance sensor and the bioimpedance sensor is utilized to collect impedance data through the conductive electrode. If the user updates the target operation corresponding to the preset position to the body temperature data acquisition operation through the user-defined instruction, if the rotating member rotates to the preset position, the executed operation comprises the following steps: the control electronic switch is used for communicating the conductive electrode with the temperature sensor and collecting body temperature data through the conductive electrode by using the temperature sensor.

As a possible implementation, the steps implemented when the processor calls the computer program in the memory further include: if a body composition detection instruction input by a user is received, controlling an electronic switch to communicate the conductive electrode with the bio-impedance sensor; judging whether the impedance data acquired by the biological impedance sensor is valid data; if yes, controlling a memory to store impedance data acquired by the biological impedance sensor; if not, controlling a display screen to display prompt information; the prompt information comprises information for prompting the pressing position of the finger and/or information for prompting the rotating piece to rotate to the preset position. According to the embodiment, after the user inputs the body composition detection instruction, the user can be guided to detect the impedance data, the user who is not familiar with the impedance data acquisition function can be helped to complete the operation, and the user experience is improved.

The above embodiments are described below with reference to a wristwatch having a vital sign data detecting function in practical applications, and the rotating member is a bezel of the wristwatch when the wrist-worn device may be a wristwatch.

The watch may include a processor, a graphics processor, a memory, a wireless communication module, a motion sensor, a position detection sensor, an ECG sensor, a bio-impedance sensor, a conductive electrode, and a bezel (equivalent to the rotating member above). The ECG sensor can measure ECG data through three conductive electrodes LA (Left Arm), RA (Right Arm), and RLD (Right Leg Driver). Two conductive electrodes LA and RLD are respectively arranged on the bottom shell of the watch, and a conductive electrode RA is arranged on a bezel or a key. If the watch is worn by the left hand of the user, the wrist of the left hand is in contact with the conductive electrodes LA and RLD, and the conductive electrodes RA of the watch frame or the keys are pressed by fingers of the right hand, so that the ECG data of the user can be measured by the ECG sensor, and the ECG data can be displayed on the display screen or the mobile phone end after being processed by the processor. The bio-impedance sensor measures the impedance of the human body through four electrodes of FIR, FVR, FIL and FVL. The processor can calculate physical sign information such as body fat rate, water content rate, muscle mass and the like of the user through a body composition algorithm by combining the measured impedance data with information such as age, sex, height, weight and the like of the user. Taking the configuration shown in FIG. 2 as an example, RLD and FIL may correspond to a first conductive electrode, LA and FVL may correspond to a second conductive electrode, RA and FIR may correspond to a third conductive electrode, and FVR may correspond to a fourth conductive electrode. The first conductive electrode, the second conductive electrode and the third conductive electrode can be used as measuring electrodes of ECG data and impedance data at the same time, and the processor controls the first conductive electrode, the second conductive electrode and the third conductive electrode to be communicated with the ECG sensor or the bioimpedance sensor respectively through the electronic switch.

Further, the case and the display of the wristwatch can be fixed elements on the wristwatch, and the bezel can be assembled to the case by a positioning and connecting mechanism such as a snap fit, and the bezel can rotate relative to the case and the display. The watch ring can be provided with a rotary mark for indicating the rotary position of the watch ring; the cover glass or the shell of the display screen is provided with a gear mark for indicating the rotation position of the bezel relative to the shell. Referring to fig. 4, fig. 4 is a schematic view of a gear identifier of a housing according to an embodiment of the present disclosure, where a first position and a second position respectively correspond to a gear identifier, 401 in fig. 4 is a rotation identifier of a bezel, 402 is a gear identifier corresponding to the first position of the housing, 403 is a gear identifier corresponding to the second position, and 404 is a key of the housing.

The watch dial defaults to displaying the current time. When the bezel is rotated to a first position (i.e., the preset position in the above) by the user, the amount of change in magnetic induction detected by the three-axis hall sensor is greater than a preset threshold T (considering the false triggering for preventing slight rotation, the present embodiment sets the threshold to T ═ 200uT), and an interrupt signal is output to wake up the processor. After the processor detects the interrupt and the sensor data sent by the three-axis Hall sensor, the processor judges that the bezel in the current state rotates to the first position, and the processor enters a corresponding sign detection function, wherein the sign detection function comprises an electrocardiogram measurement function and a body composition measurement function. When the bezel rotates to the second position, the magnetic induction intensity variation detected by the three-axis Hall sensor is larger than a preset threshold T, and an interrupt signal is output to wake up the processor. After the processor detects the interrupt and the sensor data sent by the three-axis Hall sensor, the processor judges that the bezel in the current state rotates to the second position, and the processor can enter other modes such as a motion detection mode and a flight mode.

If the user rotates the dial to the gear mark corresponding to the first position of the shell, the dial can be judged to be rotated to the first position, and the electrocardiogram measuring function is started. After the bezel is rotated to the first position, if a body composition detection instruction input by a user is received, a body composition detection function is started.

After the electrocardiogram measuring function is started, the processor controls the electronic switch, and then the conductive electrodes of the watch ring and the watch case are communicated with the ECG sensor, so that the ECG sensor collects ECG data. The processor can control the display screen to display a picture of the ECG measurement state, and store the ECG data acquired by the ECG sensor in the memory, and simultaneously draw an electrocardiogram on the display screen. The processor can prompt the user that the measurement is finished after enough ECG data is collected through the ECG sensor, and sends the ECG data to the mobile phone terminal APP through Bluetooth. The user can check the complete electrocardiogram of the measurement by using the APP at the mobile phone end, and generates analysis and suggestions aiming at the electrocardiogram. After the body composition detection function is started, the processor controls the conductive electrode switching circuit, and then the conductive electrodes of the bezel and the watch case are communicated with the biological impedance sensor, so that the biological impedance sensor collects impedance data. The processor can store the impedance data acquired by the biological impedance sensor in the memory, and operate the human body composition algorithm to calculate the impedance data to obtain the current body composition information of the user.

Referring to fig. 5, fig. 5 is a schematic diagram of a connection manner of conductive electrodes of a watch according to an embodiment of the present disclosure, the watch includes a bezel 510, an insulating partition 520, an upper case 530, a bottom case 531, a key 540, a first conductive elastic member 550 and a second conductive elastic member 551 located on the upper case, a first conductive electrode 560, a second conductive electrode 561, a third conductive electrode 562, a fourth conductive electrode 563, an electrode contact 570 of the third conductive electrode, and an electrode contact 571 of the fourth conductive electrode. The outer surface and the inner surface of the sapphire glass of the heart rate lens of the watch bottom shell are plated with communicated conductive films, and the first conductive electrode and the second conductive electrode can be the conductive films. The outer surface of the heart rate lens is at the contact position of the watch and the wrist skin. The heart rate lens inner surface is communicated with the main board through a conductive elastic piece or other conductive materials with good conductive performance. The ECG and bioimpedance sensors and related circuit components are located on the motherboard. The wrist skin thus forms an electrical path between the first conductive electrode, the second conductive electrode, and the ECG sensor and the bioimpedance sensor. The third conductive electrode and the fourth conductive electrode can be the outer surfaces of the metal watch ring, an insulating partition exists between the third conductive electrode and the fourth conductive electrode, and the outer surface of a complete watch ring is divided into two conductive electrodes through the two insulating partitions. The inner surface of the metal bezel is plated with an insulating layer except the electrode contact region, and only the electrode contact keeps good conductivity. When the bezel rotates to a set first position or a set second position, the main board penetrates through the opening at the corresponding position of the upper shell through the conductive elastic piece and is contacted with the electrode contact at the corresponding position of the bezel. The skin of the finger thus forms an electrical path with the ECG and bioimpedance sensors through the third and fourth conductive electrodes.

As a feasible implementation manner, the position detection sensor in the watch may be a three-axis hall sensor, the three-axis hall sensor is disposed on a motherboard below the bezel, a magnet may be embedded in a specific position in the bezel, and magnetic field data collected by the three-axis hall sensor changes in a process that the magnet rotates along with the bezel, so that the detection of the rotation position of the bezel may be realized. The three-axis Hall sensor can detect the change of a surrounding XYZ three-axis magnetic field and can send an interrupt signal to the processor according to a set magnetic field change quantity threshold value. The minimum variable quantity of the uniaxial magnetic induction intensity detectable by the triaxial Hall sensor is 3 uT.

Further, this embodiment can bury magnet in the bezel according to the quantity and the position of triggering the gear, can also adjust magnet size, magnet position, magnet quantity and the position of placing of triaxial hall sensor on the mainboard according to the practical application demand. For example, the first position of the watch is a position corresponding to 9 o ' clock, the second position is a position corresponding to 11 o ' clock, the gear mark of the casing comprises a default gear mark corresponding to 9 o ' clock, a first gear mark corresponding to 11 o ' clock, and a second gear mark corresponding to 7 o ' clock, and the three-axis hall sensor can be placed near the projection of the default gear mark on the main board. Magnet size, magnet quantity and magnet position all can influence the magnetic induction around the triaxial hall sensor, therefore this embodiment can adjust magnet size, magnet quantity and magnet position so that when triaxial hall sensor detects the rotatory sign and rotates respectively to default position, primary importance and second location, there is obvious difference XYZ triaxial magnetic induction. In this embodiment, 1 large magnet may be embedded at the 9 o 'clock position of the bezel, and a plurality of small magnets may be embedded in the 7-11 o' clock range. The magnetic field trigger threshold, the trigger area and the false touch prevention threshold of three gears of 7 o ' clock, 9 o ' clock and 11 o ' clock can be calibrated in the embodiment. The magnetic field trigger threshold is a magnetic field threshold for judging that the rotating identifier of the bezel rotates to a certain gear identifier, and the trigger area is an area corresponding to the rotating position of the bezel for judging that the rotating identifier of the bezel rotates to a certain gear identifier (for example, if the rotating identifier of the bezel points to an area from 6 o 'clock to 40 o' clock to 7 o 'clock, the rotating identifier is judged to rotate to a second position corresponding to 7 o' clock). The false touch prevention threshold is a safety margin set for preventing the identification confusion of a plurality of gear identifiers, and taking the second gear identifier corresponding to 7 o ' clock as an example, the magnetic induction intensities of the three axes XYZ and the three axes of 20 minutes at the left and right of the second gear identifier corresponding to 7 o ' clock, namely the magnetic induction intensities of M720x, M720y, M720z at 7 o ' clock and the magnetic induction intensities of M640x, M640y and M640z at 6 o ' clock and 40 o ' clock can be marked. In the same way, default gears corresponding to the 9 o ' clock position are marked to identify the magnetic induction of the three axes XYZ and z at the positions of 20 degrees left and right, the magnetic induction of the 9 o ' clock position is M920x, M920y, M920z, and the magnetic induction of the 8 o ' clock position is M840x, M840y and M840 z. To prevent false triggering, the size and position of the magnet are adjusted to ensure that the magnetic induction intensity of the 8-point 40 position and the magnetic induction intensity of the 7-point 20 position detected by the three-axis Hall sensor have enough safety margin. Namely: i M840x-M720x | >. Δ Mx, | M840y-M720y | >. Δ My, | M840z-M720z | >. Δ Mz. In this embodiment, Δ Mx ═ Δ My ═ Δ Mz ═ 200 uT. The delta Mx is the X-axis safety margin, the delta My is the Y-axis safety margin, and the delta Mz is the Z-axis safety margin.

Referring to fig. 6, fig. 6 is a flowchart of a method for acquiring physical sign data by using a watch according to an embodiment of the present application, where an implementation process of the embodiment may be: a user rotates the bezel, and if the magnetic induction intensity change value is larger than a preset threshold T of the three-axis Hall sensor, the three-axis Hall sensor detects and triggers an output interrupt signal so as to wake up the processor; and the processor reads the three-axis magnetic induction intensity value of the current sensor of the three-axis Hall sensor and judges the rotating position of the bezel. If the watch ring rotates to the first position, entering a process of starting an electrocardiogram measurement function; if the bezel rotates to the second position, the user-defined functions are entered, such as running outdoors, displaying a payment two-dimensional code and the like; and if the bezel rotates to other positions, the processor enters a sleep state and controls the three-axis Hall sensor to enter a low-power-consumption detection mode.

Referring to fig. 7, fig. 7 is a flowchart of ECG data acquisition based on a watch according to an embodiment of the present application, which includes the following steps:

s701: the processor controls the electronic switch to communicate the first conductive electrode, the second conductive electrode, and the third conductive electrode with the ECG sensor.
