[0018] In order to make the purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] In addition, the terms "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0020] In order to solve the problem of high hardware resource cost or difficulty in ensuring the safety of accessory information in the related art accessory identification method, the first embodiment of the present application provides an accessory identification method applied to an electronic device, the electronic device is provided with a magnetic strength detection element, which can be an element integrated in the electronic device itself or an element additionally installed during detection, and the magnetic strength detection element can be a Hall sensor or other sensor with a magnetic field strength detection function. The present embodiment takes a linear Hall sensor as an example for description. As shown in FIG. 1, the basic flowchart of the accessory identification method provided by the present embodiment includes steps 101 to 103:

[0021] In step 101, when it is detected that the target accessory is located at a preset target position of the electronic device, target magnetic strength representation data is generated based on the magnetic field strength of the magnetic component in the target accessory responding to the magnetic strength detection element.

[0022] Specifically, the embodiment performs accessory recognition based on magnetic field strength detection. A linear Hall sensor can be used to detect the magnetic field strength. As shown in FIG. 2, when the position of the magnet 10 changes, the Hall sensor 20 detects a change in the magnetic field strength, and the output magnetic strength characteristic data also changes accordingly. Thus, a magnetic component such as a magnet can be arranged in different accessories, so that when different accessories are located at the set position of the electronic device, the distance between the magnetic component in the different accessories and the linear Hall sensor or the relative position of the linear Hall sensor is different, so that the linear Hall sensor can output different magnetic strength characteristic data, which can be voltage data or current data, etc. The embodiment takes voltage data as an example for illustration. For example, as shown in FIG. 3, if the magnet 10 in the first accessory 1 is located to the left of the linear Hall sensor 20 of the electronic device 2, and the distance between the magnet 10 and the linear Hall sensor 20 is 2 mm, the linear Hall sensor 20 detects that the magnetic field strength is -2.5 GS, and outputs a voltage value of 500 mV. For the second accessory 3 in FIG. 4, the magnet 10 is located above the linear Hall sensor 20 of the electronic device 2, and the distance between the magnet 10 and the linear Hall sensor 20 is 0 mm, so the linear Hall sensor 20 detects that the magnetic field strength is 0 GS, and outputs a voltage value of 1500 mV. For the third accessory 4 in FIG. 5, the magnet 10 is located to the right of the linear Hall sensor 20 of the electronic device 2, and the distance between the magnet 10 and the linear Hall sensor 20 is 3 mm, so the linear Hall sensor 20 detects that the magnetic field strength is 3 GS, and outputs a voltage value of 3000 mV. The linear Hall sensor can be integrated with an analog-to-digital converter (ADC), so that the voltage value representing the magnetic field strength can be directly obtained. If the ADC is not integrated, the digital voltage data obtained by the ADC can be converted.

[0023] In some embodiments of the embodiment, before the magnetic strength detection element generates the target magnetic strength characteristic data based on the magnetic field strength of the magnetic component in the target accessory, the method further includes: detecting the magnetic field strength of the magnetic component in the target accessory in real time based on the magnetic strength detection element to obtain corresponding first voltage data; and if the first voltage data is within a preset voltage threshold range, determining that the target accessory is located at the preset target position of the electronic device.

[0024] Specifically, in the embodiment, a fixed position is provided on the electronic device, and when detection is needed, the target accessory is placed on the fixed position, so that different accessories have the same reference point. In the embodiment, the linear Hall sensor is used to detect whether each accessory is in the fixed position. The magnetic field strength of each magnet in the accessory used in the related scene when the accessory is in the fixed position is detected in advance, and a corresponding voltage value is output, so that a voltage threshold range is obtained. When accessory recognition is needed, the magnetic field strength of the magnet in the target accessory is detected in real time, and when the voltage value representing the magnetic field strength is in the voltage threshold range, it is determined that the target accessory is in the preset fixed position of the electronic device. Meanwhile, in the embodiment, the magnetic strength representation data obtained when the target accessory is in the fixed position is matched subsequently, and is matched with the voltage threshold range. The target magnetic strength representation data that does not belong to the target magnetic strength representation data is filtered out, so that the accuracy of the subsequent matching data can be improved.

[0025] In some other embodiments of the present embodiment, before the magnetic strength detection element generates the target magnetic strength representation data in response to the magnetic field strength of the magnetic component in the target accessory, the method further includes: detecting the magnetic field strength of the reference magnetic component in the reference accessory in the target position based on the magnetic strength detection element to obtain reference magnetic strength representation data; and if the reference magnetic strength representation data meets the magnetic strength representation data range associated with the reference magnetic component, performing the operation of generating the target magnetic strength representation data in response to the magnetic field strength of the magnetic component in the target accessory based on the magnetic strength detection element.

[0026] Specifically, in the embodiment, in order to ensure the accuracy and reliability of the detected magnetic strength representation data, the linear Hall sensor can be calibrated before magnetic strength detection, that is, a reference accessory is selected, the magnetic strength of the reference magnetic component in the reference accessory is detected based on the linear Hall sensor, and then the output reference magnetic strength representation data is matched with the magnetic strength representation data range associated with the reference magnetic component. If the reference magnetic strength representation data is in the magnetic strength representation data range, it is determined that the calibration is successful, and the subsequent operation of generating the target magnetic strength representation data in response to the magnetic field strength of the magnetic component in the target accessory can be performed.

[0027] Further, in some embodiments of the present embodiment, when the number of target magnetic strength representation data is multiple, the magnetic strength detection element generates the target magnetic strength representation data in response to the magnetic field strength of the magnetic component in the target accessory, including: detecting the magnetic field strength of the magnetic component in the target accessory when the target accessory is in different directions based on the magnetic strength detection element to obtain multiple target magnetic strength representation data; and / or, according to a preset detection number, and based on the magnetic strength detection element, detecting the magnetic field strength of the magnetic component in the target accessory when the target accessory is in the same direction to obtain multiple target magnetic strength representation data.

[0028] Specifically, in the embodiment, when the target accessory is in the preset fixed position, the detected magnetic strength characteristic data can be one or more, i.e., one detection based on the linear Hall sensor can obtain one magnetic strength characteristic data; and in order to improve the accuracy of detection, multiple detections can be performed to obtain multiple magnetic strength characteristic data, wherein, when multiple magnetic strength characteristic data are needed, the magnetic strength of the magnetic component in the same orientation can be detected a preset number of times based on the linear Hall sensor, or the magnetic strength of the magnetic component can be detected from multiple orientations, or the two methods can be combined for detection, wherein the target accessory in multiple orientations is in the preset fixed position, i.e., the target accessory can be rotated by a preset angle.

[0029] Step 102, matching the target magnetic strength characteristic data with the preset accessory index table.

[0030] Specifically, in the embodiment, when the target accessory is in the preset fixed position, the detected magnetic strength characteristic data can be one or more, i.e., one detection based on the linear Hall sensor can obtain one magnetic strength characteristic data; and in order to improve the accuracy of detection, multiple detections can be performed to obtain multiple magnetic strength characteristic data, wherein, when multiple magnetic strength characteristic data are needed, the magnetic strength of the magnetic component in the same orientation can be detected a preset number of times based on the linear Hall sensor, or the magnetic strength of the magnetic component can be detected from multiple orientations, or the two methods can be combined for detection, wherein the target accessory in multiple orientations is in the preset fixed position, i.e., the target accessory can be rotated by a preset angle.

[0031] In some embodiments of the embodiment, when the number of target magnetic strength characteristic data is multiple, matching the target magnetic strength characteristic data with the preset accessory index table comprises: screening the multiple target voltage data to obtain multiple first target voltage data; calculating the mean of the multiple first target voltage data to obtain second target voltage data; and matching the second target voltage data with the preset accessory index table.

[0032] Specifically, in the embodiment, when the number of target magnetic strength characteristic data obtained when the target accessory is in the preset fixed position of the electronic device is multiple, the obtained magnetic strength characteristic data can be screened to select a preset number of target magnetic strength characteristic data or to select target magnetic strength characteristic data with high reference, and then the first target magnetic strength characteristic data obtained by screening is subjected to mean calculation to obtain second target magnetic strength characteristic data, and finally the second target magnetic strength characteristic data is queried in the preset accessory index table; or, each first target magnetic strength characteristic data obtained by screening can be directly matched with the accessory index table, and the magnetic strength characteristic data range with the highest occurrence frequency in the matching result is used as the reference.

[0033] Further, in some embodiments of the present embodiment, the plurality of target voltage data is filtered to obtain a plurality of first target voltage data, including: calculating the sum of absolute values of differences between each target voltage data and the remaining target voltage data to obtain a plurality of sum of absolute values; comparing each sum of absolute values with a preset threshold value respectively; if there is a target sum of absolute values greater than the threshold value, the corresponding target voltage data is removed to obtain a plurality of first target voltage data.

[0034] Specifically, in the present embodiment, in order to ensure the referenceability of the mean value calculation result, data in the plurality of target magnetic strength characteristic data that is greatly different from other target magnetic strength characteristic data can be filtered out. For example, each target magnetic strength characteristic data is subtracted from the remaining target magnetic strength characteristic data, then the absolute values of each difference value corresponding to each target magnetic strength characteristic data are summed to obtain a plurality of sum of difference absolute values, then each sum of difference absolute values is compared with a pre-set threshold value, and finally the target magnetic strength characteristic data corresponding to the sum of difference absolute values greater than the threshold value is removed; or the target magnetic strength characteristic data corresponding to the maximum sum of difference absolute values in the plurality of sum of difference absolute values is removed.

[0035] Further, in some other embodiments of the present embodiment, after the target magnetic strength characteristic data is matched with the preset accessory index table, it further includes: if the target magnetic strength characteristic data does not match the corresponding magnetic strength characteristic data range in the accessory index table, outputting prompt information that the target accessory is in an abnormal state.

[0036] Specifically, in the present embodiment, if the corresponding magnetic strength characteristic data range is not matched in the accessory index table, it indicates that the accessory can be damaged or the detected magnetic strength characteristic data is abnormal (such as being interfered by other magnetic objects, etc.), and the prompt information that the accessory is in an abnormal state can be outputted to remind the relevant personnel to perform abnormal troubleshooting.

[0037] Step 103, determining the accessory identification information corresponding to the matched magnetic strength characteristic data range as the identification information of the target accessory.

[0038] Specifically, in the embodiment, when the magnetic field strength characteristic data detected according to the target accessory located at the fixed position of the electronic device matches the corresponding magnetic field strength characteristic data range in the accessory index table, the accessory identification information corresponding to the magnetic field strength characteristic data range is determined as the identification information of the target accessory. For example, when the magnetic field strength characteristic data range [1498, 1502] is matched in the accessory index table according to the voltage value 1500 mV, it is determined that the target accessory is the second accessory. Similarly, any connected normal accessory can be identified according to different voltage values. Thus, the accessory identification method based on magnetic field strength detection provided in the embodiment can detect whether an accessory is connected and identify different types of accessories. Moreover, the magnetic field strength detection element and the magnetic component can be hidden and installed, so that the accessory-related information cannot be easily stolen, which is beneficial to ensure the safety of the accessory information. Meanwhile, the hardware implementation of the identification method is simple, and only needs to set the magnetic field strength detection element on the electronic device side and the magnetic component on the accessory side, so the overall cost is low and too much volume is not occupied. Furthermore, the judgment accuracy of the magnetic detection element such as the Hall sensor is high (up to + / - 0.05 mm), so the identification of multiple accessories can be realized in a small size.

[0039] Based on the technical solution of the embodiment of the application, when it is detected that the target accessory is located at the preset target position of the electronic device, the target magnetic field strength characteristic data is generated based on the magnetic field strength of the magnetic component in the target accessory responding to the magnetic field strength detection element. The target magnetic field strength characteristic data includes voltage data. The target magnetic field strength characteristic data is matched with the preset accessory index table. The accessory index table includes the mapping relationship between the magnetic field strength characteristic data range and the accessory identification information. The accessory identification information corresponding to the matched magnetic field strength characteristic data range is determined as the identification information of the target accessory. Through the implementation of the solution of the application, the magnetic field strength of the magnetic component in the accessory is detected to obtain the corresponding magnetic field strength characteristic data, and then the identification information of the accessory is obtained by looking up the table according to the magnetic field strength characteristic data. Thus, the identification method can hide the identification information of the accessory, which is beneficial to ensure the safety of the accessory information. Meanwhile, compared with the related art, the identification method does not need too many hardware resources, only needs to install the magnetic field strength detection element on the electronic device and the magnetic component on the accessory, so the hardware resource cost is effectively saved.

[0040] The method in FIG. 6 is a refined accessory identification method provided by an embodiment of the application. The accessory identification method includes:

[0041] Step 601: Real-time detection of the magnetic field strength of the magnetic component in the target accessory to obtain the corresponding first magnetic field strength characteristic data.

[0042] Step 602: If the first magnetic field strength characteristic data is in the preset threshold range, it is determined that the target accessory is located at the preset target position of the electronic device.

[0043] Step 603, generating a plurality of second magnetic strength characterization data in response to the magnetic field strength of the magnetic component in the target accessory;

[0044] Step 604, screening the plurality of second magnetic strength characterization data to obtain a plurality of third magnetic strength characterization data;

[0045] Step 605, calculating the mean of the plurality of third target magnetic strength characterization data to obtain target magnetic strength characterization data;

[0046] Step 606, matching the target magnetic strength characterization data with a preset accessory index table;

[0047] Step 607, determining the accessory identification information corresponding to the matched magnetic strength characterization data range as the identification information of the target accessory.

[0048] It should be understood that the size of the serial number of each step in the embodiment does not mean the order of execution of the steps, and the execution order of each step should be determined by its function and inherent logic, and should not constitute the only limitation on the implementation process of the embodiment of the application.

[0049] Based on the above technical solutions of the embodiment of the application, by detecting the magnetic field strength of the magnetic component in the target accessory in real time, when the voltage value representing the magnetic field strength is within the preset voltage threshold range, it is determined that the target accessory is in the preset fixed position of the electronic device, a plurality of voltage values detected when the target accessory is in the fixed position are obtained, the obtained voltage values are screened to select a preset number of target voltage values or select target voltage values with high reference, then the target voltage values obtained by screening are subjected to mean value calculation, and finally the target voltage mean value is queried in the preset accessory index table. If the corresponding voltage range is matched in the accessory index table, the accessory identification information corresponding to the voltage range can be determined as the identification information of the target accessory. Through the implementation of the application, it can be detected whether the accessory is connected, and different types of accessories can be identified. Since the magnetic strength detection element and the magnetic component can be hidden and installed, the accessory related information cannot be easily stolen, which is beneficial to ensure the safety of the accessory information. At the same time, the hardware implementation of the identification method is simple, only the magnetic strength detection element needs to be arranged on the electronic device side and the magnetic component needs to be arranged on the accessory side, the overall cost is low, and too much volume is not occupied. Furthermore, the judgment accuracy of the magnetic detection element such as the Hall sensor is high, and a plurality of accessories can be identified in a small size.
