The method, the device, the watch and the storage medium for identifying the magnetic device category provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

With the development of communication technology, the functions in the wristwatch are increasing. The watch can detect the magnetic field and the change of the magnetic field of the position of the Hall sensor through the Hall sensor, so that different functions, such as watch strap detection, are realized.

In the related art, the hall sensor is an integrated sensor which takes the hall effect as the working basis and consists of a hall element and an accessory circuit thereof, and can detect the magnetic field and the change of the magnetic field at the position of the hall sensor. Different functions, such as watch band detection, can be realized through the collocation detection of the Hall sensor and different magnetism. The key principle is as follows: the magnetic fields of materials and sizes are different, the external magnetic fields are vector fields, and the different magnetic fields are identified through the Hall sensor, so that different states are distinguished; for example, the different magnetic fields differ in intensity, and the watch can distinguish between different magnetic types by different intensity thresholds, so that the watch can determine whether to link with the wristband based on the magnetic types.

However, disturbances of magnetic fields exist everywhere in life, such as: soft magnetism generated by current during internal operation, strong magnetic field hard magnetic interference such as external magnetism, and the like. Meanwhile, the magnetic function used for identification can have the scene of being magnetized and demagnetized under certain conditions, and if the state of judgment of the Hall sensor is relatively more, the interference scene can cause false triggering and even false judgment of the originally set judgment threshold value, and the user experience is affected. Thus, the accuracy of the watch in performing functions through the magnetic components is poor.

In the identification method, the identification device, the watch and the storage medium provided by the application, as the watch can correct the magnetic field background noise corresponding to the magnetic device in the watch through the correction amount; therefore, under the condition that the watch has magnetic field interference, the watch can correct magnetic field background noise corresponding to the magnetic device, the watch can determine the first magnetic field increment based on the corrected magnetic field background noise, judge whether the first magnetic field increment belongs to the first magnetic field increment range, and further determine the type of the mounted watchband or execute the function of matching the type of the target magnetic device corresponding to the first magnetic field increment range, so that the accuracy of the watch executing the function through the magnetic component is improved.

The identification method provided in the embodiment of the present application may be implemented by an identification device, where the identification device may be a wristwatch, and the wristwatch includes a watchband, where the watchband includes a magnetic device, or a functional module in the wristwatch. The technical scheme provided in the embodiment of the present application will be described below by taking a wristwatch as an example.

An embodiment of the application provides an identification method, and fig. 1 shows a flowchart of the identification method provided by the embodiment of the application. As shown in fig. 1, the identification method provided in the embodiment of the present application may include the following steps 201 to 204.

Step 201, when the watch is not mounted with a watchband, the watch acquires a first magnetic field strength of the watch.

In this application embodiment, the wrist-watch can acquire first magnetic field strength through hall sensor.

The first magnetic field strength is the sum of the magnetic field strengths of the magnetic components in the wristwatch through magnetic field interference.

Illustratively, the magnetic components in the watch may include at least one of: magnet, loudspeaker and motor are inhaled to magnetism.

Optionally, in an embodiment of the present application, the first magnetic field strength includes a first magnetic field strength vector.

Illustratively, in connection with FIG. 1, as shown in FIG. 2, the above-described step 201 may be implemented by the following step 201 a.

Step 201a, the watch obtains first magnetic field intensity information of a magnetic device in the watch through a Hall sensor in the watch, and maps the first magnetic field intensity information to a coordinate system of the watch to obtain a first magnetic field intensity vector.

The first magnetic field strength may be, for example, a sum of vectors of magnetic field strengths of the magnetic device after the magnetic field disturbance.

Optionally, in this embodiment of the present application, after the watch acquires the first magnetic field strength of the magnetic device through the hall sensor, the watch may compare the first magnetic field strength with a first preset threshold, and if the first magnetic field strength is greater than or equal to the first preset threshold, the watch does not use the first magnetic field strength, and reacquires the first magnetic field strength until the first magnetic field strength parameter is less than the first preset threshold.

It should be noted that, because the first magnetic field strength is obtained through the magnetic attraction magnet, the loudspeaker, the motor and other hard magnetic devices in the watch, the magnetic field strength corresponding to the magnetic devices is usually smaller, and if the first magnetic field strength obtained by the watch is greater than or equal to the first preset threshold value, the first magnetic field strength parameter obtained by the watch is inaccurate.

Optionally, in the embodiment of the present application, the watch may save the first magnetic field strength if the first magnetic field strength parameter is less than a first preset threshold.

In this embodiment of the present application, the first magnetic field strength information includes a magnitude and a direction of a magnetic field strength.

In the embodiment of the application, the watch can calibrate a coordinate system based on the Hall sensor.

Illustratively, the hall sensor is taken as a reference point, the origin of coordinates is set by the center position of the hall sensor, the vertical upward direction perpendicular to the hall sensor is taken as a Z-axis, the horizontal direction parallel to the hall sensor is taken as an X-axis, and the horizontal direction perpendicular to the X-axis is taken as a Y-axis.

The absolute value of each axis in the coordinate system represents the magnitude of the magnetic field in the direction, and the positive and negative values represent the direction.

In this embodiment of the present application, the first magnetic field strength vector may be stored in the watch in a coordinate form.

For example, assuming that the first magnetic field strength information is that the magnetic field direction is the vertically upward direction and the magnetic field strength is 10, the first magnetic field strength vector may be (0, 10).

In this embodiment of the application, the wrist-watch can map magnetic field strength information to the coordinate system to obtain the magnetic field strength vector, so that the wrist-watch can confirm first magnetic field correction based on the magnetic field strength vector, reduced the calculated amount of wrist-watch, promoted the computational efficiency that the wrist-watch confirmed.

Step 202, when the difference value between the first magnetic field intensity and the magnetic field background noise is greater than or equal to a preset value, the watch determines a correction amount according to the difference value.

In this embodiment of the present application, the magnetic field noise is a magnetic field strength of at least one magnetic device in the wristwatch, which is not interfered by a magnetic field.

In an embodiment of the present application, the magnetic device may include at least one of the following: hard magnetic devices such as magnetism attraction, a loudspeaker, a motor and the like are arranged in the watch.

Optionally, in an embodiment of the present application, the magnetic field interference may include at least one of: hard magnetic interference and soft magnetic interference.

Illustratively, the environment of the watch is changed, and there is a strong magnetism in the environment, and the strong magnetism has a large magnetic field strength, so that strong magnetic interference, namely the hard magnetic interference, occurs to the magnetic devices in the watch; or magnetic field interference generated by large-current operation in the watch, namely the soft magnetic interference.

In this embodiment of the present application, the electronic device may obtain the magnetic field noise vector corresponding to the magnetic field noise through the above step 201 a.

Illustratively, assuming that the coordinates corresponding to the first magnetic field intensity vector are (X1, Y1, Z1), and the coordinates corresponding to the magnetic field noise vector corresponding to the magnetic field noise is (X3, Y3, Z3), the first magnetic field correction amount is (Xfix, yfix, zfix); wherein xfix=x1-X3; fix=y1-Y3; zfix=z1-Z3.

And 202, correcting the magnetic field noise based on the correction amount by the watch to obtain the second magnetic field intensity.

In this embodiment of the present application, the wristwatch may process the magnetic field noise based on the correction amount to obtain the second magnetic field strength parameter.

For example, assuming that the vector corresponding to the magnetic field noise floor is (X1, Y1, Z1) and the correction amount is (X5, Y5, Z5), the vector corresponding to the second magnetic field strength parameter is (Xv, yv, zv); wherein xv=x1+x5, yv=y1+y5, zv=z1+z5.

Alternatively, in the embodiment of the present application, as shown in fig. 3 in conjunction with fig. 1, the above step 202 may be specifically implemented by the following step 202 a.

Step 202a, when the first condition is satisfied, the wristwatch corrects the magnetic field noise based on the correction amount, and obtains the second magnetic field strength.

In an embodiment of the present application, the above meeting the first condition includes any one of the following:

the watch is not provided with a watchband;

it can be understood that after the watchband is installed, the correction and compensation process is stopped, no matter whether the outside is interfered or not, the correction and compensation process cannot be reflected in the use of the user, and therefore the use experience of the user is guaranteed.

Furthermore, the watchband is not arranged on the watch; or after the watchband is installed on the watch, under the condition that the watch is disconnected from the watchband, the watch can correct the magnetic field noise based on the current magnetic field environment, so that the accuracy of the magnetic field noise can be ensured.

The first magnetic field strength is less than a first threshold value;

it will be appreciated that, based on the above embodiments, it is known that the first magnetic field strength is smaller than the first threshold value, which indicates that the first magnetic field strength is normal, and the wristwatch can correct and compensate for the noise of the magnetic field.

The watch is not provided with a watchband, the first magnetic field intensity is smaller than a first threshold value, and the deviation between the first magnetic field intensity and the magnetic field intensity in the current environment of the watch is larger than or equal to a second threshold value.

For example, when the watch is not provided with a watchband and the first magnetic field strength does not exceed the first threshold value, the watch can read the magnetic field strength in the current environment in real time and compare with the magnetic field noise, and when the deviation between the magnetic field strength in the current environment and the magnetic field noise does not exceed ±50, the magnetic device in the watch is considered to be undisturbed, and when the deviation between the magnetic field strength in the previous environment and the magnetic field noise exceeds ±50, the magnetic device in the watch is considered to be disturbed, and the watch can correct and compensate the magnetic field noise.

In this embodiment of the application, the wrist-watch can revise the magnetic field noise floor based on first condition, has promoted the magnetic field noise floor and has revised the diversification and the flexibility of scene.

Step 203, in the case of a wristwatch with a watchband installed, the wristwatch acquires a third magnetic field strength of the wristwatch, and determines a first magnetic field increment based on the third magnetic field strength and the second magnetic field strength.

In this embodiment of the present application, the third magnetic field strength parameter is a magnetic field strength detected by the wristwatch after the wristwatch is mounted with the watchband.

It will be appreciated that after the wristwatch is fitted with the wristband, the magnetic field strength detected by the hall sensor will change due to the proximity of the new magnetic component, and the wristwatch can obtain the magnetic field strength of the magnetic component in the proximity of the hall sensor, i.e. the third magnetic field strength.

For example, since the band of the wristwatch contains magnetic components such as a magnet, the intensity of the magnetic field detected by the hall sensor must be increased when the band approaches the wristwatch.

Optionally, in the embodiment of the present application, the watch may set a magnetic field strength acquisition time, so that the hall sensor may automatically acquire the magnetic field strength of the magnetic device in the watch and the magnetic field strength of the magnetic device after the magnetic field interference periodically.

The third magnetic field strength may be a third magnetic field strength vector, for example.

In the embodiment of the application, the watch may determine the difference between the third magnetic field intensity vector and the second magnetic field intensity vector as the first magnetic field increment.

For example, the watch may store the third magnetic field strength vector and the second magnetic field strength vector in the watch by way of three-dimensional coordinates; for example, if the three-dimensional coordinates corresponding to the second magnetic field intensity vector are (X1, Y1, Z1), the three-dimensional coordinates corresponding to the third magnetic field intensity vector are (X2, Y2, Z2), the first magnetic field increment is (Xadd, yadd, zadd), where xadd=x2—x1; yadd=y2-Y1; zadd=z2-Z1.

Step 204, the watch determines the type of the watchband installed according to the first magnetic field increment range or performs the function of matching the target magnetic device category corresponding to the first magnetic field increment range.

In this embodiment of the present application, the first magnetic field increment range includes a first magnetic field increment.

In this embodiment of the present application, the first magnetic field increment range may be stored in first information, where the first information may include N second magnetic field increment ranges, and N is a positive integer.

Illustratively, the watch may store N second magnetic field increment ranges in the form of a table.

It will be appreciated that the magnetic properties of the interior of the wristband may vary with respect to the increase in magnetic field due to differences in shape, direction of magnetization, size, etc. The watch can record the magnitude of each different watchband magnetic field increment and the magnetic type corresponding to the magnitude of the watchband magnetic field increment through simulation and actual measurement, and records the magnetic type into a table, and can be specifically shown in the following table 1

Magnetic type	X-axis	Y-axis	Z-axis
				Magnetism a	Xa1<X<Xa2	Ya1<Y<Ya2	Za1<Z<Za2
Magnetism b	Xb1<X<Xb2	Yb1<Y<Yb2	Zb1<Z<Zb2
				Magnetism c	Xc1<X<Xc2	Yc1<Y<Yc2	Zc1<Z<Zc2
Magnetism d	Xd1<X<Xd2	Yd1<Y<Yd2	Zd1<Z<Zd2

TABLE 1

It should be noted that, because there is a tolerance fluctuation in the magnetic dimensions, the increment of the magnetic field caused by each watchband is not generally fixed, so in table 1, the increment of each axis corresponding to each magnetic type is generally not a constant value, but a fluctuation range, and the wristwatch can determine the specific watchband type by identifying whether the first increment of the magnetic field falls within the range of the above comparison table.

In this embodiment of the present application, different types of magnetism may correspond to different system topics, and after the watch changes the watchband, the watch may determine the magnetic type of the watchband according to table 1 above, and further determine the function corresponding to the magnetic type.

Illustratively, the above-described functions may be: updating the system theme in the watch.

For example, assuming that the system theme corresponding to the magnetism a is a leisure theme, after the wristwatch is linked with the watchband containing the magnetism a, the wristwatch may update the system theme in the current wristwatch to the leisure theme; after the watchband of the watch is updated to the watchband containing the magnetism b, and the system theme corresponding to the magnetism b is the sports theme, the watch can update the leisure theme to the operation theme after the watch is linked with the watchband containing the magnetism b.

In the method for identifying the category of the magnetic device provided by the embodiment of the application, the watch can acquire the first magnetic field intensity of the watch under the condition that the watch is not provided with the watchband; determining a correction amount according to the difference value when the difference value between the first magnetic field intensity and the magnetic field background noise is larger than or equal to a preset value; correcting the magnetic field noise based on the correction amount to obtain a second magnetic field intensity; acquiring a third magnetic field strength of the watch when the watch is provided with the watchband, and determining a first magnetic field increment based on the third magnetic field strength and the second magnetic field strength; the type of the watchband to be mounted is determined according to the first magnetic field increment range or a function of matching the category of the target magnetic device corresponding to the first magnetic field increment range is executed. Wherein the first field increment range comprises a first field increment. In the scheme, the watch can correct the magnetic field background noise corresponding to the magnetic device in the watch through the correction amount; therefore, under the condition that the watch has magnetic field interference, the watch can correct magnetic field background noise corresponding to the magnetic device, the watch can determine the first magnetic field increment based on the corrected magnetic field background noise, judge whether the first magnetic field increment belongs to the first magnetic field increment range, and further determine the type of the mounted watchband or execute the function of matching the type of the target magnetic device corresponding to the first magnetic field increment range, so that the accuracy of the watch executing the function through the magnetic component is improved.

Optionally, in an embodiment of the present application, as shown in fig. 4 in conjunction with fig. 1, before step 204, the identification method provided in an embodiment of the present application further includes the following step 301.

Step 301, the watch matches the first magnetic field increment with N second magnetic field increment ranges.

In this embodiment of the present application, each of the N second magnetic field increment ranges corresponds to a magnetic device class, and N is a positive integer.

In this embodiment of the present application, each of the N magnetic device types corresponds to at least one function in the wristwatch.

In this embodiment of the present application, the first magnetic field increment range is one of N second magnetic field increment ranges.

In this embodiment of the present application, after obtaining the first magnetic field increment, the watch may traverse N second magnetic field increment ranges based on the first magnetic field increment, so as to find a first magnetic field increment range that matches the first magnetic field increment.

In this embodiment of the application, the wrist-watch can confirm the first magnetic field increment scope that matches with first magnetic field increment from N second magnetic field increment scope to the wrist-watch can confirm the magnetism device category that the magnetism device in the watchband corresponds, and then confirms the function in the wrist-watch, so, has promoted the flexibility that the wrist-watch confirmed the function in the wrist-watch.

Optionally, in an embodiment of the present application, as shown in fig. 5 in conjunction with fig. 1, before step 204, the method for identifying a magnetic device class provided in an embodiment of the present application further includes the following steps 401 and 402.

Step 401, the watch obtains magnetic field offset between magnetic field noise floor and magnetic field noise floor after magnetic field interference.

In this embodiment of the present application, the above magnetic field offset is a magnetic field offset generated by a magnetic device after magnetic field interference in a coordinate system.

For example, the watch may detect the magnetic intensity vector of the magnetic device after the magnetic field disturbance by the hall sensor.

The magnetic field offset is also the sum of the magnetic field offsets of the magnetic devices in the watch arrangement.

Illustratively, assuming that the magnetic strength vector of the magnetic device after the magnetic field disturbance is (X4, Y4, Z4), the magnetic strength vector of the magnetic device, that is, the vector of the first magnetic strength is (X1, Y1, Z1), the magnetic field offset is (Xoffset, yoffset, zoffset); wherein xoffset=x4—x1; yoffset=y4—y1; zoffset=z4-Z1.

Step 402, the watch updates N preset magnetic field increment ranges according to the magnetic field offset, and obtains the N second magnetic field increment ranges.

In this embodiment of the present application, after the watch obtains the magnetic field offset, the watch may superimpose the magnetic field offset on N preset magnetic field increment ranges, so as to obtain N second magnetic field increment ranges.

It will be appreciated that if the magnetic type lookup table of table 1 is still used, the identification error of the watchband type and even the loss of function may be caused. In the case where the disturbance offset is already known, the wristwatch can generate a new magnetic type lookup table from the magnetic field offset, as shown in table 2.

Magnetic type	X-axis	Y-axis	Z-axis
				Magnetism a	Xa1+X offset <X<Xa2+X offset	Ya1+Y offset <Y<Ya2+Y offset	Za1+Z offset <Z<Za2+Z offset
Magnetism b	Xb1+X offset <X<Xb2+X offset	Yb1+Y offset <Y<Yb2+Y offset	Zb1+Z offset <Z<Zb2+Z offset
				Magnetism c	Xc1+X offset <X<Xc2+X offset	Yc1+Y offset <Y<Yc2+Y offset	Zc1+Z offset <Z<Zc2+Z offset
Magnetism d	Xd1+X offset <X<Xd2+X offset	Yd1+Y offset <Y<Yd2+Y offset	Zd1+Z offset <Z<Zd2+Z offset

TABLE 2

In the embodiment of the application, the updated magnetic type comparison table is superimposed with the magnetic field interference offset on the original basis, and the new comparison table is used for judging, so that the influence of interference on type judgment can be eliminated.

In the embodiment of the application, when certain interference exists outside the Hall device by introducing the magnetic field offset, the magnetic field can be corrected and compensated, so that the normal function is ensured.
