Abstract

A method and system for determining whether a bracelet is separated from the wrist. The method comprises the following steps: determining, by means of a range sensor (5), a distance between a rear surface (3) of a bracelet to the nearest surface to the rear surface (3) of the bracelet, and feeding the numerical value of the distance back to a controller, such that the controller can determine whether the bracelet is being worn. The above technical solution enables automatic determination of a state of a bracelet including an off-wrist state, an on-wrist state, and an incorrectly-worn state, particularly the incorrectly-worn state. When a bracelet is in the incorrectly-worn state, inaccurate measurement data is obtained when operation modules of the bracelet are activated, causing a user to misjudge their own physical condition, and leading to potentially serious consequences. The technical solution of the present invention enables determination of whether a bracelet is in the off-wrist state or on-wrist state, and furthermore, whether the bracelet is being worn in a correct manner, thereby enabling a user to have accurate knowledge of their own various physical parameters, facilitating arrangement of exercises, and improving health.

In the following description, numerous specific details are set forth However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced without omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be employed. In other instances, various aspects of the invention may be <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt;

[0019] As shown in the schematic diagram of the prior art wristband shown in FIG. 1, the head 1 has a touch screen 2, and the touch screen 2 is attached with three touch channels A, B, and C to display content on the touch screen. When the finger sequentially slides from the touch channel A, the touch channel B, and the touch channel C (ie, slides from left to right), switching from the first interface to the second interface on the touch display screen can be realized. When the fingers are ordered from the touch channel. , touch channel B and touch Touching channel A (ie, sliding from right to left) 吋, the transition from the third interface to the fourth interface on the touch display screen can be realized. The second interface may be the third interface, or may not be the third interface; the fourth interface may be the first interface, or may not be the first interface, that is, the left and right sliding movements of the finger (the above must be sequentially touched) The three touch channels can realize the conversion of the interface of the wristband. Of course, it can also be implemented not only to realize the function of converting the above-mentioned wristband interface, but also to implement other functions, such as a left sliding screen, a right sliding screen, and the like. Reference numeral 3 in Fig. 1 denotes a reverse side 3 opposite to the touch display screen 2 and in proximity or contact with the wrist, and a heart rate detector 4 is disposed on the reverse side 3. When the heart rate detection module 吋, the heart rate detector 4 can be activated to detect the pulse of the user or the operator. The wristband of the prior art described in FIG. 1 needs an artificial heart rate detection module or other modules to achieve the corresponding functions after being worn. When the wristband is removed, the heart rate detection module or other must be manually closed. The module can save power by turning off the corresponding function; or, the heart rate detection module of the wristband and other modules are always in the state of being activated, and the wristband still consumes a large amount of power even if it is not worn.

[0020] Here, the "sleep state" is defined, and the sleep state is to remove the functions of the wristband display function and the distance sensor function (such as step counting, heart rate detection function, sleep monitoring, GPS positioning function, WIFI positioning function). Etc.) All turned off. Define the "working status" as the status of all the functional modules that the starter ring has.

[0021] As shown in FIG. 2, in order to solve the above problems of the prior art, a distance sensor 5 is disposed beside the heart rate detector 4 of the reverse side 3, and the distance sensor 5 can detect between the reverse side 3 of the smart bracelet and the human skin. The distance includes a controller, the distance sensor 5 and the heart rate detector 4 are connected to the controller, wherein the controller presets a distance range between the user wearing the wristband and the back surface of the wristband 3 and the surface of the user's skin. The preset range includes at least a reasonable distance (for example, less than or equal to 3 mm), an over distance (such as (3, 8] mm), and an unworn distance (for example, greater than 8 mm), and the reasonable distance is a reasonable wearing of the wristband by the user. a distance between the opposite side of the wristband and the user's skin. The distance is that the user does not wear or wear the wristband properly, and the distance between the opposite side of the wristband and the user's skin is greater than the reasonable distance. The maximum value is less than or equal to a certain threshold (the threshold value may be the farthest distance from the skin according to the heart rate sensor in the test phase according to the heart rate sensor, or may be in the experimental stage, the user a distance range in which the wristband 佩戴 is the farthest distance from the skin on the reverse side of the skin, and the unworn distance is a distance range in which the distance between the reverse side of the bracelet and the user's skin is greater than the threshold; The controller also presets the user Reasonable heart rate (such as 50-120 beats / min or other reasonable range, the reasonable range includes at least the heart rate of the human sleep sputum and the heart rate of the user's strenuous exercise).

[0022] As shown in FIG. 3, the method for determining whether the bracelet is handed off is as follows:

[0023] Step 1: The distance sensor 5 is used to determine the distance of the back surface of the wristband 3 from the surface closest to the back surface 3 of the bracelet, and the distance value is fed back to the controller.

[0024] Step 2: The controller compares the distance value with the preset range; if the distance value is in the unworn distance, the process proceeds to step 3; if the distance value is in the above-mentioned over distance, then the process proceeds to Step 4; if the distance value is within the above reasonable distance, then proceeds to step 5;

[0025] Step 3: If the distance value is in the above-mentioned unworn distance, the controller determines that the wristband is in the off-hand state, and when in the off-hand state, the controller controls the wristband to make the bracelet Dormancy

Preferably, the dormant state is to turn off all functions except the wristband display function and the distance sensor function (such as step counting, heart rate detection function, sleep monitoring, GPS positioning function, WIFI positioning function, etc.). status;

[0026] Step 4: If the distance value is at the above-mentioned super-distance, the controller activates the heart rate detector 4, and the heart rate detector 4 detects the heart rate value of the object closest to the back surface of the wristband 3, if The heart rate value is in the range of the preset user heart rate value. Then, it is determined that the wristband is in an unworn state, and the controller controls the touch display screen 2 to display “not worn”. The controller controls the vibrator vibration and/or the alarm alarm of the wristband; if the heart rate value is not within the preset user heart rate value range, determining that the wristband is in the off-hand state, the controller controls the wristband Go to sleep state;

[0027] Step 5: If the distance value is within the reasonable distance, the controller activates the heart rate detector 4, and the heart rate detector 4 detects the heart rate value of the object closest to the back surface 3 of the wristband. If the heart rate value is in the preset user heart rate value range, then it is determined that the wristband is in a wearing state, and the wristband is in an active state mode; if the heart rate value is not in the preset user heart rate The value range determines that the wristband is in a hand-off state, and the controller controls the wristband to enter a sleep state.

[0028] When the touch display screen 2 displays "not worn", the user adjusts the wearing mode and then proceeds to step one above. The distance sensor can determine the distance value to be detected. [0029] Through the above technical solution, it is possible to automatically determine the state in which the wristband is in a state of "off hand", "wearing state" and "not wearing", especially the state of "not wearing", the wristband is not worn. In a good state, when the various working modules of the wristband are activated, the measured data is inaccurate, causing the user to misjudge the physical condition of the user, which has serious consequences. The technical solution can be “away from the hand”. The judgment of the state "and the wearing state" determines whether the wristband is properly worn when wearing the wristband. Based on this, the user can more accurately grasp the various parameters of the body, which is beneficial to the reasonable adjustment of the movement mode. Come to good health.
