FIG. 1 is a schematic diagram illustrating the structure of an electronic device in accordance with an exemplary embodiment; fig. 2 is a schematic structural diagram of another electronic device shown in accordance with an example embodiment. As shown in fig. 1-2, the electronic device may include various types of mobile phones, tablets, and the like, and the disclosure is not limited thereto. In an embodiment, the electronic device may be provided with magnetic field disturbance devices, such as the camera module 11, the motor 12, the earpiece 13, the speaker 14, and the like shown in fig. 1, and the magnetic field disturbance devices include hard magnetic or soft magnetic materials, which can form the magnetic field disturbance area 10 shown in fig. 1 in the electronic device, and cause magnetic field disturbance to the devices located in the magnetic field disturbance area 10. In an embodiment, the electronic device may be provided with current interference devices, such as the charging module 2 shown in fig. 2, which may generate relatively large operating currents during operation, and the operating currents may form a current interference area 20 shown in fig. 2, so as to cause current interference to devices located in the current interference area 20.
For the electronic compass, since the electronic compass is easily interfered by the magnetic field interference region 10 and the current interference region 20 during the operation process, if the electronic compass is placed in the magnetic field interference region 10 or the current interference region 20, the electronic compass receives the corresponding magnetic field interference or current interference, thereby affecting the data accuracy of the electronic compass.
However, as the functions of the electronic device are increased, the demand of the user for the electronic device to be light and thin is increased, so that the available space inside the electronic device is decreased. As shown in fig. 3, after the magnetic field interference region 10 and the current interference region 20 are superimposed, there is almost no position inside the electronic device that can avoid the magnetic field interference region 10 and the current interference region 20, and therefore, no matter where the electronic compass is disposed, at least one of the magnetic field interference and the current interference may be applied, thereby affecting the accuracy of the electronic compass.
Therefore, the present disclosure improves the structure of the electronic apparatus, so that the electronic apparatus can obtain higher accuracy.
As shown in fig. 3, in the case that a magnetic field interference device and a current interference device are built in the electronic device, a first electronic compass 31 and a second electronic compass 32 may be included, wherein the first electronic compass 31 is located in the magnetic field interference region 10 generated by the magnetic field interference device and is not located in the current interference region 20 generated by the current interference device, and the second electronic compass 32 is located in the current interference region 20 and is not located in the magnetic field interference region 10.
In one embodiment, the first electronic compass 31 and the second electronic compass 32 may be connected to the same set I2C (or other types) of buses of the electronic device, and the address information of the two electronic compasses should be different to ensure that the electronic device (such as the CPU of the electronic device) can accurately distinguish the two electronic compasses.
Based on the electronic device with the improved structure, the following direction determining method as shown in fig. 4 can be adopted to determine the direction more accurately; wherein the method may comprise the steps of:
in step 402, an application scenario in which the electronic device is located is identified.
In an embodiment, when the electronic device is in different types of application scenarios, the magnetic field interference device and the current interference device are not always in an operating state, so that at least one of the first electronic compass 31 and the second electronic compass 32 has no interference or less interference, and the accuracy of the finally determined azimuth information can be improved by increasing the weight value of the undisturbed or less-interfered electronic compass.
In step 404, the weight values of the first electronic compass 31 and the second electronic compass 32 corresponding to the application scenes are determined.
In step 406, the output results of the first electronic compass 31 and the second electronic compass 32 are weighted according to the determined weight values, so as to obtain the azimuth information.
In one embodiment, the orientation information may be calculated according to the following formula:
Dcompass＝A1*Dcompass1+A2*Dcompass2
wherein D iscompassFor the final calculated orientation information, Dcompass1Is the output data of the first electronic compass 31, Dcompass2As the output data of the second electronic compass 32, a1 is a weight value corresponding to the first electronic compass 31, and a2 is a weight value corresponding to the second electronic compass 32.
In one embodiment, application scenarios may be divided into two categories: in the first application scenario, the magnetic field interference device is in an operating state, and the current interference device is in a non-operating state, at this time, the first electronic compass 31 located in the magnetic field interference region 10 may be greatly influenced, and the second electronic compass 32 located in the current interference region 20 may be slightly influenced, so that the weight value a1 corresponding to the first electronic compass 31 may be set to be smaller than the weight value a2 of the second electronic compass 32. In the second application scenario, the current interference device is in an operating state, and the magnetic field interference device is in a non-operating state, at this time, the second electronic compass 32 located in the current interference area 20 may be greatly influenced, and the first electronic compass 31 located in the magnetic field interference area 10 may be slightly influenced, so that the weight value a2 of the second electronic compass 32 may be set to be smaller than the weight value a1 corresponding to the first electronic compass 31.
In an embodiment, the first class application scenario and the second class application scenario may be divided according to whether the electronic device is in a charging state.
For example, when the electronic device is not in a charging state, the charging module 2 is not necessarily in an operating state, and thus the second electronic compass 32 is not affected by current interference, but the user has a high probability to use other functions of the electronic device, which results in the first electronic compass 31 having a high probability to be affected by magnetic field interference, and thus the weight value a1 corresponding to the first electronic compass 31 may be set to be smaller than the weight value a2 of the second electronic compass 32, for example, a1 is 0.2, and a2 is 0.8.
When the electronic device is in the charging state, the charging module 2 is inevitably in the operating state, so the second electronic compass 32 will be affected by the current interference, but the user has a smaller probability of using other functions of the electronic device, so that the first electronic compass 31 has a smaller probability of being affected by the magnetic field interference, and therefore, the weight value a1 corresponding to the first electronic compass 31 can be set to be greater than the weight value a2 of the second electronic compass 32, for example, a1 is 0.8, and a2 is 0.2.
In an embodiment, the first electronic compass 31 and the second electronic compass 32 may have the same performance, for example, the two electronic compasses may have the same brand and the same model, so as to avoid performance problems and cause a larger deviation of the output azimuth information thereof, and prevent the accuracy of the final azimuth information from being affected.
In one embodiment, a greater number of electronic compasses can be installed in the electronic device, and these electronic compasses can be classified into two categories: at least one electronic compass disposed in the magnetic field interference region 10 and at least one electronic compass disposed in the current interference region 20, but based on the above principle, corresponding weight values may be set for different types of electronic compasses in different scenes, which is not described herein again.
Corresponding to the foregoing embodiments of the orientation determining method, the present disclosure also provides embodiments of an orientation determining apparatus.
