Referring to fig. 1, fig. 1 is a flowchart illustrating a method for identifying a model of a wristband according to an embodiment of the present disclosure.
The specific steps may include:
s101: detecting the change of the environmental magnetic field data of the equipment body;
wherein, this embodiment can be applied to wrist wearing equipment such as intelligent wrist-watch, intelligent bracelet, and above-mentioned wrist wearing equipment can include equipment principal and detachable wrist strap, the wrist strap that equipment was worn to the wrist is provided with magnet, the magnet diverse that sets up in the wrist strap of each model. As a possible embodiment, a magnet may be provided at a connection position of the wrist band and the device body.
S102: judging whether the original wrist strap connected with the equipment main body is replaced or not according to the change of the environmental magnetic field data; if yes, entering S103; if not, the process goes to S101;
before this step, can judge that the wrist strap of being connected with the equipment main part is former wrist strap, can be provided with magnet on the former wrist strap, environmental magnetic field data can change when former wrist strap is dismantled from the equipment main part, and environmental magnetic field data also can change when former wrist strap is changed for new wrist strap, and consequently this step can judge whether former wrist strap is changed according to the change of the environmental magnetic field data of equipment main part in the time of predetermineeing. The Hall sensor can be arranged in the equipment main body, and then the Hall sensor is utilized to detect the magnetic field data.
As a possible implementation manner, a threshold value for replacing the wrist strap is preset for this embodiment, and whether the original wrist strap is replaced is determined based on the threshold value: detecting the variation of the environmental magnetic field data of the equipment main body; judging whether the variation of the environmental magnetic field data of the equipment main body is larger than a threshold value or not; if yes, the original wrist strap connected with the equipment main body is judged to be replaced.
S103: acquiring magnetic field data of a new wrist strap currently connected with the equipment main body;
the step is established on the basis that the original wrist strap which is originally connected with the equipment main body is judged to be detached from the equipment main body, the environmental magnetic field data can be continuously acquired, and then the magnetic field data of the new wrist strap is determined based on the environmental magnetic field data.
Specifically, after the original wrist strap is detached from the device main body, the device main body may have a situation that the wrist strap is not connected for a period of time, and at this time, the numerical value of the environmental magnetic field data may become smaller; when installing new wrist strap to the equipment main part on, the numerical value of environmental magnetic field data can increase, and the environmental magnetic field data that the former wrist strap produced is different with the environmental magnetic field data that new wrist strap produced.
In order to improve the detection accuracy, the present embodiment may acquire actual magnetic field data of the wristband connecting position of the device body within a preset time period; and setting the average value of the actual magnetic field data in a preset time length as the magnetic field data of the new wrist strap currently connected with the equipment main body. In this embodiment, after it is determined that the original wristband connected to the device body is replaced, a preset time is delayed before magnetic field data of a new wristband currently connected to the device body is acquired, so that the step of acquiring magnetic field data of the new wristband currently connected to the device body is performed after the preset time is delayed.

The wrist equipment of wearing that this embodiment provided includes wrist strap and equipment main part, and the wrist strap is provided with magnet, and when the wrist strap was installed in equipment main part, equipment main part can realize that the wrist strap is changed and is detected and wrist strap model detects according to magnetic field data. Above-mentioned process need not user input wrist strap model, can confirm the wrist strap model of new wrist strap according to the corresponding relation of magnetic field data and wrist strap model, can automated inspection wrist strap model.
Referring to fig. 2, fig. 2 is a schematic view of a magnetizing direction of a magnet according to an embodiment of the present application, fig. 2 shows 4 magnetizing directions, where N denotes an N pole of the magnet, S denotes an N pole of the magnet, and an arrow denotes a magnetic induction line direction. In the example shown in fig. 2, the magnets of the same size and material are distinguished by the magnetizing direction, so that the distinction of 4 kinds of magnets can be realized. For magnets with the same material and the same magnetizing direction, the larger the volume is, the higher the magnetic induction intensity is, so that the magnets can be distinguished by different magnet volumes. For magnets with the same magnetizing direction and magnet volume, the magnets can be distinguished by different magnet materials. For example, the BHmax (maximum energy product) of NdFeB is 5 to 12 times that of ferrite magnet and 3 to 10 times that of AlNiCo magnet.
Can realize the differentiation of different magnets through the combination based on these three kinds of factors of direction of magnetizing, magnet volume and magnet material, and then realize the differentiation of multiple wrist strap model, specific compound mode as follows:
The thickness and space of the wristband are limited, and the number that can be achieved by only volume division of the magnets is limited. Assuming that the embedding of the wrist strap is satisfied at the same time, the magnetic induction difference of any axis is more than M, and the magnets with different volumes are V1, V2, V3 and V4 which have 4 sizes respectively. By combining 4 different charging directions (e.g., N1, N2, S1, and S2) for these 4 sizes, 16 magnet types can be used to distinguish different bracelets, namely:
N1V1；N1V2；N1V3；N1V4；
N2V1；N2V2；N2V3；N2V4；
S1V1；S1V2；S1V3；S1V4；
S2V1；S2V2；S2V3；S2V4。
For the same size magnet, assume that the magnetic induction of ferrite magnet is B1, alnico magnet is B2, and the magnetic induction of ndfeb is B3. By combining the 3 different magnets with 4 different magnetizing directions (e.g., N1, N2, S1, and S2), 12 types of magnets can be used to distinguish different wristbands:
N1B1；N1B2；N1B3；
N2B1；N2B2；N2B3；
S1B1；S1B2；S1B3；
S2B1；S2B2；S2B3。
For magnets of the same charging direction, different magnet volumes (e.g., V1 and V2) and different magnet materials (e.g., B1, B2, and B3) can produce the following 12 combinations for distinguishing different watchbands:
V1B1；V1B2；V1B3；
V2B1；V2B2；V2B3；
V1B1；V1B2；V1B3；
V2B1；V2B2；V2B3。
Taking 4 kinds of magnetizing directions, 3 kinds of magnet volumes and 3 kinds of magnet materials as examples, 4x3x 3-36 combinations can be generated.
As a possible embodiment, the present embodiment may install a magnet for each wristband in the following manner: combining the magnetizing directions of the types A, the volumes of the types B of magnets and the materials of the types C of magnets to obtain a plurality of different magnet parameter configuration schemes; mounting a respective magnet to a wristband of the wrist-worn device according to the magnet parameter configuration scheme such that each wristband type has a unique corresponding magnet parameter configuration scheme. Wherein, the direction of magnetizing, magnet volume and magnet material homoenergetic influence the magnetic field data that magnet produced, and the magnet parameter that each wrist strap model corresponds can be obtained through the combination of above three kinds of factors to this embodiment, can realize the matching of multiple wrist strap model through this mode.
Referring to fig. 3, fig. 3 is a flowchart of a method for determining a wristband type of a new wristband according to magnetic field data according to an embodiment of the present application, which is further described in S104 in the corresponding embodiment of fig. 1, and the wristband type may be determined in the following manner:
s301: comparing the magnetic field data of the new wrist strap with the reference magnetic field data of a plurality of preset wrist straps to obtain the magnetic induction intensity difference value of each preset wrist strap and the new wrist strap;
s302: setting the preset wrist strap with the minimum magnetic induction intensity difference value as an alternative wrist strap;
s303: judging whether the difference value of the magnetic induction intensity of the new wrist strap and the alternative wrist strap is smaller than or equal to a preset value; if yes, entering S304; if not, the flow is ended.
S304: and setting the wrist strap model of the new wrist strap as the wrist strap model of the alternative wrist strap.
In the above embodiment, reference magnetic field data of a plurality of preset wristbands may be preset, and the actually detected magnetic field data of the new wristband is compared with the reference magnetic field data, so as to determine the wristband type of the new wristband according to the similarity of the magnetic field data.
As a feasible implementation manner, the three-axis hall sensor may be used in the device main body to collect magnetic field data, and accordingly, it may be determined whether the magnetic induction difference is smaller than or equal to a preset value by the following method, including:
determining an X-axis magnetic induction difference value, a Y-axis magnetic induction difference value and a Z-axis magnetic induction difference value of the new wristband and the alternative wristband; judging whether the X-axis magnetic induction difference value is smaller than or equal to a first X-axis preset value or not to obtain a first judgment result; judging whether the Y-axis magnetic induction difference value is smaller than or equal to a first Y-axis preset value or not to obtain a second judgment result; and judging whether the Z-axis magnetic induction difference value is less than or equal to a first Z-axis preset value or not, and obtaining a third judgment result. If the first judgment result, the second judgment result and the third judgment result are yes, judging that the difference value of the magnetic induction intensity of the new wrist strap and the alternative wrist strap is smaller than or equal to the preset value; and if the first judgment result, the second judgment result and the third judgment result are not yes, judging that the difference value of the magnetic induction intensity of the new wrist strap and the alternative wrist strap is larger than the preset value.
In order to avoid the model identification error caused by the shake when the new wristband is mounted on the device main body, the embodiment can also perform judgment for many times in the following manner:
after determining the difference value of the magnetic induction of the X axis, the difference value of the magnetic induction of the Y axis and the difference value of the magnetic induction of the Z axis of the new wristband and the alternative wristband, the method further comprises the following steps: judging whether the X-axis magnetic induction difference value is larger than a second X-axis preset value or not to obtain a fourth judgment result; wherein the second X-axis preset value is greater than the first X-axis preset value; judging whether the Y-axis magnetic induction difference value is larger than a second Y-axis preset value or not to obtain a fifth judgment result; wherein the second Y-axis preset value is greater than the first Y-axis preset value; judging whether the Z-axis magnetic induction difference value is larger than a second Z-axis preset value or not to obtain a sixth judgment result; wherein the second Z-axis preset value is greater than the first Z-axis preset value. And if the fourth judgment result, the fifth judgment result and the sixth judgment result are yes, judging that the new wrist strap is a wrist strap with an unknown model. If the first judgment result, the second judgment result, the third judgment result, the fourth judgment result, the fifth judgment result and the sixth judgment result are not yes, updating the cycle number, and judging whether the cycle number is greater than a cycle threshold value; if yes, judging that the new wrist strap is the wrist strap of unknown type, or judging that the magnetic field change in the environment is triggered by mistake; and if not, re-entering the step of acquiring the magnetic field data of the new wrist strap currently connected with the equipment main body.
The flow described in the above embodiment is explained below by a smart watch in practical use. The wrist strap of the intelligent watch is the watchband.
Most of the current intelligent watches need users to select favorite dial pictures and themes in hundreds of dial applications by themselves. Some smartwatches can utilize the hall sensor in the bracelet to detect whether the bracelet is packed into the watchband at the built-in magnet of bracelet. But conventional hall sensor can only distinguish whether the wrist strap state is put into to the bracelet, can't distinguish whether the wrist strap of difference is put into to the bracelet. How to conveniently help consumers to match with various dials and watchbands becomes a real demand of wearing products.
In order to solve the problem that exists among the above-mentioned correlation technique, this application provides a can dismantle watchband automated inspection's scheme, and embedded magnet in the watchband of this scheme utilizes the adaptation of the different watchbands of triaxial hall sensor detection in the intelligent wrist-watch. The intelligent watch is matched with different watchbands, and automatically switches to the watch face picture and the theme of adaptation, so that the inconvenience of manually selecting the watch face and the theme by a consumer is avoided.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a smart watch according to an embodiment of the present disclosure, where the smart watch may include, but is not limited to, a microprocessor MCU, a graphics processor, a memory, a speaker, a microphone, a button, a motor, a display module, a power management module, a rechargeable battery, a motion health sensor module, a wireless communication module, and a three-axis hall sensor. The microprocessor MCU is an operation control part of the intelligent wearable device and can finish the operations of instruction fetching, instruction execution, information exchange with an external memory and a logic component and the like. The graphics processor can draw the graphics content and drive the display module to perform graphics display. The memory may store various applications and associated data. The display module may display information of the system processing module, such as pictures, videos, UIs, and the like. The wireless communication module may be, but is not limited to, a bluetooth module, a WiFi module, a 4G mobile communication module, etc., through which the terminal device can make a connection with an external device (a mobile phone) or a network (e.g., the internet). The exercise health sensor module includes, but is not limited to, an acceleration sensor, a gyroscope, a PPG heart rate sensor, etc., which detects the user's exercise and health data. The three-axis hall sensor is used to detect the magnetic induction at the X, Y, Z three axes of the different magnets embedded in the wristband.
Referring to fig. 5, fig. 5 is a schematic diagram of components of an intelligent watch provided in the present embodiment, in fig. 5, 501 is a three-axis hall sensor, 502 is a watch case, 503 is a magnet, 504 is a watch band, and 505 is a watch band rotation axis. Triaxial hall sensor can set up the position that is close to the watchband at intelligent wrist-watch mainboard, and this embodiment can be close to the regional embedding magnet of watchband pivot at the watchband. The minimum volume of the magnet can be determined according to the distance d between the three-axis Hall sensor and the magnet and the sensitivity of the three-axis Hall sensor. The watchband is far away from the watch body by more than 1cm, and the variation of the magnetic induction intensity is larger than a threshold value M of triggering the three-axis Hall sensor (in order to avoid the influence of false triggering and an environmental magnetic field, M is generally 200-300 uT). The position of the three-axis Hall sensor is fixed, and in order to ensure that the Hall sensor can accurately identify the magnetic induction intensity of different magnets, the larger the distance d is, the larger the volume of the needed magnet is. After the minimum volume of the magnet is determined, the embodiment can design the specific appearance of the magnet according to the width and the style of the watchband. The embodiment can be used for embedding corresponding different magnets in watchbands of each type (such as color or type). MCU judges the watchband model that the user used at present through the different magnet of triaxial Hall sensor discernment.
The determination for different magnets is as follows: the magnetic induction intensity of different magnets read by the three-axis Hall sensor in the watchband is at least different in a certain axis and is larger than a threshold value M. By combining three factors of magnetizing direction, magnet volume and magnet material, more than one hundred magnets with obvious magnetic induction difference in X, Y, Z three axes can be realized.
Referring to fig. 6, fig. 6 is a flowchart illustrating watchband detection and fitting provided in the embodiment of the present application, which specifically includes the following steps:
s610: detecting the variation of the environmental magnetic induction intensity by a three-axis Hall sensor;
s620: and if the variation of the environmental magnetic induction intensity is larger than the threshold value M, sending an interrupt signal to the MCU.
Before receiving the interrupt signal, the MCU can be in a sleep state, and the Hall sensor sends the interrupt signal to the MCU to wake up the MCU to execute subsequent operation.
S630: the MCU starts a timer T and delays the waiting time T.
Wherein, the time for assembling the watchband can be reserved for the user through the delayed waiting.

specifically, the selected one of the plurality of sets of difference values with the smallest difference value includes an X-axis magnetic induction difference value | Δ Mx |, a Y-axis magnetic induction difference value | Δ My |, and a Z-axis magnetic induction difference value | Δ Mz |.
