Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

Currently, electronic devices are generally provided with control keys, and most of the electronic devices adopt a control key in a physical spring mode, and meanwhile, some electronic devices also adopt a control key in a hall sensor mode. As shown in fig. 1, in an electronic device integrated with an audio function, a plurality of different control positions may be switched by a control key to perform different audio control, for example, the control of mute, vibration, and ringing may be implemented by switching the control key to the different control positions. Alternatively, the control key for realizing the mute, vibration, and response switching control may be referred to as a "three-stage key", which can realize the function switching of three gear positions of the upper, middle, and lower three control positions.

The three-section type key adopts the same mechanical key to realize three key functions. The mechanical key is simple to realize, can not be interfered by the outside and is stable, but the mechanical key is large in structure, occupies a large structural space and is poor in waterproofness. The Hall sensor type key structure is smaller, the waterproof performance of the whole machine can be enhanced, but if the Hall sensor type key is adopted, the calculation is easy to deviate when being interfered, and the identification result is inaccurate.

In order to solve the problems, the inventor discovers through long-term research and proposes a method, a device, an electronic device and a storage medium for determining the key positions, which are provided by an embodiment of the application, by performing interference detection on the double Hall sensors and performing key position identification according to the detected interference result, the accuracy of identification can be improved. The specific method for determining the key position is described in detail in the following embodiments.

The working principle of the hall sensor will be described below.

The hall sensor is a magnetic field sensor made according to the hall effect. Hall effect is one of the magnetoelectric effects, which was found in 1879 when investigating the conductive mechanism of metals. It was found that semiconductors, conductive fluids, and the like have such effects, and that the hall effect of semiconductors is much stronger than that of metals, and various hall elements made by using such phenomena are widely used in industrial automation technology, detection technology, information processing, and the like. Hall effect is a fundamental approach to study the performance of semiconductor materials. The important parameters such as the conductivity type, the carrier concentration and the carrier mobility of the semiconductor material can be judged through the Hall coefficient measured by a Hall effect experiment.

As is known from the principle of the hall effect, the magnitude of the hall potential depends on: rh is a Hall constant, which is related to the semiconductor material; i is the bias current of the Hall element; b is the magnetic field intensity; d is the thickness of the semiconductor material.

For a given hall device, UH will depend entirely on the measured magnetic field strength B when the bias current I is fixed.

One hall element generally has four lead-out terminals, two of which are input terminals for the bias current I of the hall element, and the other two are output terminals for the hall voltage. If the two output terminals form an outer loop, a hall current is generated. In general, the setting of the bias current is usually given by an external reference voltage source; if the precision requirement is high, the reference voltage source is replaced by a constant current source. In order to achieve high sensitivity, some Hall elements are provided with a coating alloy with high magnetic permeability on a sensing surface; the Hall potential of the sensor is larger, but saturation occurs at about 0.05T, and the sensor is only suitable for being used under low-limit and small-range conditions.

As shown in fig. 2, when a control current I is applied across the semiconductor sheet and a uniform magnetic field of magnetic induction B is applied in the vertical direction of the sheet, a hall voltage of potential difference UH is generated in the direction perpendicular to the current and magnetic field.

The magnetic field has a Hall semiconductor chip through which a constant current I is passed from A to B. Under the action of lorentz force, the electron current of I is shifted to one side when passing through the hall semiconductor, and the sheet generates a potential difference in the CD direction, which is a so-called hall voltage.

The hall voltage varies with the intensity of the magnetic field, the stronger the magnetic field, the higher the voltage, the weaker the magnetic field, the lower the voltage, the smaller the hall voltage value, usually only a few millivolts, but the voltage can be amplified by an amplifier in the integrated circuit to be enough to output a stronger signal. If the hall ic is made to perform sensing, mechanical means are required to change the magnetic induction. For example, a rotating impeller may be used as a switch for controlling the magnetic flux, and when the impeller blades are in the air gap between the magnet and the hall ic, the magnetic field deviates from the integrated chip and the hall voltage is extinguished. Thus, the change of the output voltage of the Hall integrated circuit can indicate a certain position of the impeller driving shaft, and the Hall integrated circuit chip can be used as an ignition timing sensor by utilizing the working principle. The Hall effect sensor belongs to a passive sensor, and can work only by an external power supply, so that the Hall effect sensor can detect the running condition of low rotating speed.

As shown in fig. 3 and 4, in the embodiment of the present application, a control key (not shown) may be disposed on a middle frame of the electronic device, and a first hall sensor, a second hall sensor, and a magnet may be disposed in the middle frame of the electronic device, where the control key is used to switch between a plurality of control positions to drive the magnet to move between the first hall sensor and the second hall sensor. It can be understood that, the above-mentioned button structure of electronic equipment through the control position of switching control button, can drive the position of change magnet between first hall sensor and second hall sensor, and the change of magnet position can change the magnetic flux between magnet and the first hall sensor and the magnetic flux between magnet and the second hall sensor to can confirm the control position that the control button was switched according to the size of the magnetic flux that first hall sensor sensed and the size of the magnetic flux that the second sensor sensed, in order to carry out the control adjustment of electronic equipment's corresponding function.

As an implementation manner, a sliding block can be further arranged in the middle frame of the electronic device, the magnet is arranged on the sliding block, and the sliding block is connected with the control key. Based on the above, when the control buttons are switched to move in a plurality of control positions, the sliding block can be enabled to move along with the movement, and accordingly, the sliding block can drive the magnet to move, so that the magnet is driven to move between the first Hall sensor and the second Hall sensor.

As an example, the plurality of control positions may include an upper, middle, and lower three control positions, corresponding to the "upper" control position for controlling silence, corresponding to the "middle" control position for controlling vibration, corresponding to the lower control position for controlling ringing, the control key may be switched in the upper, middle, and lower three control positions in response to a toggle operation triggered by a user, and accordingly, the magnet may be moved up and down back and forth between the first hall sensor and the second hall sensor based on the switching of the control key, staying in the fixed three positions to achieve the control of silence, vibration, or implementation of the ringing function.

As shown in fig. 5, in the electronic device, the first hall sensor and the second hall sensor are connected to the AP end of the access point through an IIC protocol (IIC is a synchronous half duplex communication mode, and is composed of two communication signal lines, namely, a data line SDA and a clock line SCL), so as to realize data transmission, and meanwhile, each of the first hall sensor and the second hall sensor has an interrupt output port connected to the AP, so that the switch control key wakes up the AP to perform state detection under the standby condition. Alternatively, the first hall sensor and the second hall sensor may be linear hall sensors.

Referring to fig. 6, fig. 6 is a flowchart illustrating a method for determining a key position according to an embodiment of the present application. The method is used for carrying out interference detection on the double Hall sensors and carrying out recognition of the key positions according to the detected interference results, so that the recognition accuracy can be improved. In a specific embodiment, the key position determining method is applied to the key position determining apparatus 200 shown in fig. 16 and the electronic device 100 (fig. 17) provided with the key position determining apparatus 200. The specific flow of the present embodiment will be described below by taking an electronic device as an example, and it will be understood that the electronic device applied in the present embodiment may include a smart phone, a tablet computer, a wearable electronic device, and the like, which is not limited herein. In this embodiment, a control key is provided on a middle frame of the electronic device, where a first hall sensor, a second hall sensor and a magnet are provided in the middle frame, the control key is used to switch between a plurality of control positions so as to drive the magnet to move between the first hall sensor and the second hall sensor, and the method for determining the key position specifically includes the following steps:

Step S110: the current first Hall quantity acquired by the first Hall sensor is acquired, and the current second Hall quantity acquired by the second Hall sensor is acquired.

It can be understood that when the control key is located at a certain control position among the plurality of control positions, the magnet is correspondingly located at a certain position between the first hall sensor and the second hall sensor, and then the magnet can generate a hall effect with the first hall sensor and the second hall sensor respectively at the position, and then the first hall sensor can acquire the hall quantity of the first hall sensor and the magnet, which is used as the current first hall quantity, and the second hall sensor can acquire the hall quantity of the second hall sensor and the magnet, which is used as the current second hall quantity. Alternatively, the hall quantity may include a hall voltage or a hall potential.

In this embodiment, the electronic device may acquire the current first hall amount acquired by the first hall sensor, and acquire the current second hall amount acquired by the second hall sensor. The current first hall amount acquisition parameter and the current second hall amount acquisition parameter should be the same, for example, the current first hall amount acquisition time and the current second hall amount acquisition time should be the same, the current first hall amount acquisition temperature and the current second hall amount acquisition temperature should be the same, and the present first hall amount acquisition temperature and the present second hall amount acquisition temperature should be the same, which is not limited herein.

Step S120: and determining an interference result based on the current first Hall amount and the current second Hall amount, wherein the interference result comprises the presence or absence of external magnetic field interference.

In this embodiment, in the case where the current first hall amount and the current second hall amount are obtained, the interference result may be determined based on the current first hall amount and the current second hall amount, where the interference result includes the presence or absence of external magnetic field interference.

In some embodiments, the electronic device may obtain and store in advance a preset first hall amount in the case where the control key is the same as the control position where the control key is currently located and there is no external magnetic field interference (the first hall sensor collects in the case where there is no external magnetic field interference), and may obtain and store in advance a preset second hall amount in the case where the control key is the same as the control position where the control key is currently located and there is no external magnetic field interference (the second hall sensor collects in the case where there is no external magnetic field interference). Based on the above, under the condition that the current first Hall amount and the current second Hall amount are obtained, the current first Hall amount and the preset first Hall amount can be compared, the current second Hall amount and the preset second Hall amount are compared, if the comparison result represents that the current first Hall amount is matched with the preset first Hall amount, and the current second Hall amount is matched with the preset second Hall amount, the interference result can be determined to be that no external magnetic field interference exists; if the comparison result indicates that the current first Hall quantity is not matched with the preset first Hall quantity, and/or the current second Hall quantity is not matched with the preset second Hall quantity, the interference result can be determined to be that the external magnetic field interference exists.

In some embodiments, under the condition that the current first hall amount and the second current hall amount are obtained, difference calculation can be performed on the current first hall amount and the current second hall amount to obtain a current hall amount difference value, sum calculation is performed on the current first hall amount and the current second hall amount to obtain a current hall amount sum value, and whether the interference result is external magnetic field interference or not is determined based on the current hall amount difference value and the current hall amount sum value.

Step S130: and determining a target control position corresponding to the control key from the plurality of control positions based on the interference result, the current first Hall amount and the current second Hall amount.

In this embodiment, in the case of obtaining the interference result, the target control position corresponding to the control key may be determined from a plurality of control positions based on the interference result, the current first hall amount, and the current second hall amount.

As an example, assuming that the plurality of control positions includes three control positions of up (up), middle (middle), down (down), a target control position corresponding to the control key may be determined from among the control position up, the control position middle, and the control position down based on the interference result, the current first hall amount, and the current second hall amount, for example, the control position up is determined as a target control position, the control position down is determined as a target control position, and the like, without limitation.

In some embodiments, in the case of obtaining the interference result, a position calculation manner corresponding to the interference result may be determined, and the current first hall amount and the current second hall amount are calculated based on the position calculation manner corresponding to the interference result, so as to determine a target control position corresponding to the control key from the plurality of control positions. Optionally, if the disturbance result is that there is no external magnetic field disturbance, a first position calculation mode with which there is no external magnetic field disturbance may be determined, and the current first hall amount and the current second hall amount are calculated based on the first position calculation mode, so as to determine a target control position corresponding to the control key from the plurality of control positions. The disturbance results are that the external magnetic field disturbance exists, a second position calculation mode with the external magnetic field disturbance exists can be determined, and the current first Hall quantity and the current second Hall quantity are calculated based on the second position calculation mode, so that a target control position corresponding to the control key is determined from a plurality of control positions.

According to the method for determining the key position, the current first Hall quantity acquired by the first Hall sensor is acquired, the current second Hall quantity acquired by the second Hall sensor is acquired, the interference result including the existence of external magnetic field interference or the absence of external magnetic field interference is determined based on the current first Hall quantity and the current second Hall quantity, and the target control position corresponding to the control key is determined from a plurality of control positions based on the interference result, the current first Hall quantity and the current second Hall quantity, so that interference detection is carried out on the double Hall sensors, key position identification is carried out according to the detected interference result, and the accuracy of identification can be improved.

Step S240: and determining the interference result based on the current Hall amount difference value and the current Hall amount sum value, wherein the interference result comprises the presence or absence of external magnetic field interference.

In this embodiment, in the case where the current hall amount difference value and the current hall amount sum value are obtained, the interference result may be determined based on the current hall amount difference value and the current hall amount sum value, that is, the presence of the external magnetic field interference or the absence of the external magnetic field interference may be determined based on the current hall amount difference value and the current hall amount sum value.

In some embodiments, the electronic device may acquire and store a preset hall amount difference value (a difference value between a hall amount acquired by the first hall sensor in the absence of the external magnetic field interference and a hall amount acquired by the second hall sensor in the absence of the external magnetic field interference) in which the control key is the same as the control position in which the control key is currently located, and in the absence of the external magnetic field interference, and may acquire and store a preset hall amount sum value (a sum value of a hall amount acquired by the first hall sensor in the absence of the external magnetic field interference and a hall amount acquired by the second hall sensor in the absence of the external magnetic field interference) in which the control key is the same as the control position in which the control key is currently located.

Referring to fig. 8, fig. 8 is a flowchart illustrating step S240 of the method for determining a key position shown in fig. 7. The following details the flow shown in fig. 8, and the method may specifically include the following steps:

step S241: and determining a relation between the current Hall quantity difference value and a calibrated Hall quantity difference value range corresponding to each of the plurality of control positions as a first relation, wherein the calibrated Hall quantity difference value range is determined based on a difference value and an interference difference margin between calibrated Hall quantities acquired by the first Hall sensor and the second Hall sensor respectively at the same control position of the plurality of control positions.

Optionally, the electronic device may preset and store a calibrated hall difference value range corresponding to each of the plurality of control positions, where the calibrated hall difference value range is determined based on a difference value between calibrated hall amounts acquired by the first hall sensor and the second hall sensor at the same control position of the plurality of control positions and an interference difference margin. Alternatively, the interference difference margin may be determined based on empirical values.

In some embodiments, as shown in table 1, it is assumed that the plurality of control positions include three control positions of up (up), middle (middle), and down (down), and in the context of electronic device production or post calibration, the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position up are a (the unit may be voltage mv) and d, the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position middle are b and e, and the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position down are c and f. Then, the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position up is a-d, the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position middle is b-e, and the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position down is c-f.

	Up (up)	Middle (middle)	Lower (Down)
				First Hall sensor	a	b	c
Second Hall sensor	d	e	f
				Hall difference	a-d	b-e	c-f

Further, as shown in the following table 2, assuming that the interference difference margin is n1, the calibrated hall difference value range corresponding to the control position up is a-d-n1 to a-d+n1, wherein a-d-n1 is the calibrated hall difference value minimum corresponding to the control position up, and a-d+n1 is the calibrated hall difference value maximum corresponding to the control position up; the range of the calibrated Hall difference value corresponding to the control position middle is from b-e-n1 to b-e+n1, wherein b-e-n1 is the minimum difference value of the calibrated Hall quantity corresponding to the control position middle, and b-e+n1 is the maximum difference value of the calibrated Hall quantity corresponding to the control position middle; the range of the calibrated Hall difference value corresponding to the control position down is from c-f-n1 to c-f+n1, wherein c-f-n1 is the minimum difference value of the calibrated Hall quantity corresponding to the control position down, and c-f+n1 is the maximum difference value of the calibrated Hall quantity corresponding to the control position down. Based on this, the calibrated hall difference value range corresponding to each of the plurality of control positions includes: a-d-n 1-a-d+n1, b-e-n 1-b-e+n1, and c-f-n 1-c-f+n1.

					Up (up)	n1	a-d	a-d-n1	a-d+n1
Middle (middle)	n1	b-e	b-e-n1	b-e+n1
					Lower (Down)	n1	c-f	c-f-n1	c-f+n1

As an example, assume a=127, b=94, c=52, d=50, e=86, f=127, n1=15. Then, the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position up is a-d=127-50=77, the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position middle is b-e=94-86=8, and the difference between the calibrated hall amounts respectively collected by the first hall sensor and the second hall sensor at the control position down is c-f=52-127= -75. The range of the calibrated Hall difference corresponding to the control position up is a-d-n 1-a-d+n1=77-15-77+15=62-92, the range of the calibrated Hall difference corresponding to the control position middle is b-e-n 1-b-e+n1=8-15-8+15= -7-23, and the range of the calibrated Hall difference corresponding to the control position down is c-f-n 1-c-f+n1= -75-15 to-75+15= -90 to-60. At this time, the calibrated hall difference value ranges corresponding to the respective control positions include: 62-92, -7-23 and-90 to-60.

In this embodiment, when the current hall amount difference value is obtained, the current hall amount difference value may be compared with the calibrated hall amount difference value ranges corresponding to the plurality of control positions, respectively, so as to determine a relationship between the current hall amount difference value and the calibrated hall amount difference value ranges corresponding to the plurality of control positions, and use the relationship as the first relationship. Alternatively, the first relationship may include that the current hall amount difference is within the corresponding calibrated hall amount difference range, or that the current hall amount difference is not within the corresponding calibrated hall amount difference range.

In some embodiments, when the current hall amount difference is obtained, the current hall amount difference may be simultaneously compared with the calibrated hall amount difference ranges corresponding to the plurality of control positions, respectively, or the current hall amount difference may be sequentially compared with the calibrated hall amount difference ranges corresponding to the plurality of control positions, respectively, and the like, which is not limited herein.

In some embodiments, comparing the current hall quantity difference value to the calibrated hall quantity difference value range may include: comparing the current Hall quantity difference value with the calibrated Hall quantity minimum difference value in the calibrated Hall quantity difference value range to judge whether the current Hall quantity difference value is equal to or larger than the calibrated Hall quantity minimum difference value in the calibrated Hall quantity difference value range, and comparing the current Hall quantity difference value with the calibrated Hall quantity maximum difference value in the calibrated Hall quantity difference value range to judge whether the current Hall quantity difference value is smaller than or equal to the calibrated Hall quantity maximum difference value in the calibrated Hall quantity difference value range.

Step S242: determining a relationship between the current hall amount and value and the calibrated hall amount and value range corresponding to each of the plurality of control positions as a second relationship, wherein, the calibrated hall amount and value range is determined based on a sum value and an interference sum value margin between calibrated hall amounts respectively acquired by the first hall sensor and the second hall sensor at a same control position of the plurality of control positions.

Alternatively, the electronic device may preset and store a calibrated hall amount and a value range corresponding to each of the plurality of control positions, where the calibrated hall amount and the value range are determined based on a sum value and an interference sum value margin between the calibrated hall amounts acquired by the first hall sensor and the second hall sensor at the same control position among the plurality of control positions.

As an example, assume a=127, b=94, c=52, d=50, e=86, f=127, n2=20.

Alternatively, the second relationship may include that the current hall amount and value is within the corresponding calibrated hall amount and value range, or that the current hall amount and value is not within the corresponding calibrated hall amount and value range.

In some embodiments, in the case of obtaining the current hall amount and value, the current hall amount and value may be simultaneously compared with the calibrated hall amount and value ranges respectively corresponding to the plurality of control positions, or the current hall amount and value may be sequentially compared with the calibrated hall amount and value ranges respectively corresponding to the plurality of control positions, or the like, which is not limited herein.

In the present embodiment, in the case where the first relationship and the second relationship are obtained, the interference result may be determined based on the first relationship and the second relationship, that is, it may be determined whether there is external magnetic field interference or no external magnetic field interference based on the first relationship and the second relationship.

As an example, assuming that the current first hall amount is 120 and the current second hall amount is 55, the current hall amount difference is 120-55=65, the current hall amount sum is 120+55=175, wherein the current hall amount difference 65 is in the range of the calibrated hall difference value range 62-92 corresponding to the control position up, the current hall amount sum 175 is in the range of the calibrated hall difference value range 157-197 corresponding to the control position up, and the interference result is determined to be that no external magnetic field interference exists. Assuming that the current first hall quantity is 137 and the current second hall quantity is 60, the current hall quantity difference value is 137-60=77, and the current hall quantity sum value is 137+60=237, wherein the current hall quantity difference value 77 is in the range of the calibrated hall quantity difference value range 62-92 corresponding to the control position up, the current hall quantity sum value 237 is not in any calibrated hall quantity sum value range, and the interference result is determined to be that the external magnetic field interference exists.

Step S250: and determining a target control position corresponding to the control key from the plurality of control positions based on the interference result, the current first Hall amount and the current second Hall amount.

The specific description of step S250 is referred to step S130, and will not be repeated here.

Compared with the method for determining the key position shown in fig. 6, the method for determining the key position further performs difference calculation on the current first hall amount and the current second hall amount to obtain a current hall amount difference value, performs sum calculation on the current first hall amount and the current second hall amount to obtain a current hall amount sum value, and determines an interference result based on the current hall amount difference value and the current hall amount sum value, so that accuracy of the determined interference result can be improved.

Referring to fig. 9, fig. 9 is a flowchart illustrating a method for determining a key position according to an embodiment of the present application. The method is applied to the electronic device, a control key is arranged on a middle frame of the electronic device, a first hall sensor, a second hall sensor and a magnet are arranged in the middle frame, the control key is used for switching among a plurality of control positions so as to drive the magnet to move between the first hall sensor and the second hall sensor, a flow shown in fig. 9 is described in detail, and the method for determining the key position specifically comprises the following steps:

Step S310: the current first Hall quantity acquired by the first Hall sensor is acquired, and the current second Hall quantity acquired by the second Hall sensor is acquired.

Step S320: and determining an interference result based on the current first Hall amount and the current second Hall amount, wherein the interference result comprises the presence or absence of external magnetic field interference.

The specific description of step S310 to step S320 refer to step S110 to step S120, and are not described herein.

Step S330: if the interference result is that no external magnetic field interference exists, calculating a difference value between the current first Hall quantity and the current second Hall quantity to obtain a current Hall quantity difference value.

In this embodiment, if it is determined that the interference result is that no external magnetic field interference exists, a difference value between the current first hall amount and the current second hall amount may be calculated, so as to obtain a current hall amount difference value.

Step S340: and determining a calibration Hall difference value range where the current Hall difference value is located from calibration Hall difference value ranges corresponding to the control positions respectively as a target calibration Hall difference value range, wherein the calibration Hall difference value range is determined based on the difference value and the interference difference margin between the calibration Hall quantities acquired by the first Hall sensor and the second Hall sensor at the same control position in the control positions respectively.

In some embodiments, the electronic device may preset and store a calibrated hall difference value range corresponding to each of the plurality of control positions, where the calibrated hall difference value range is used as a criterion of the current hall difference value. Therefore, in this embodiment, when the current hall amount difference is obtained, the current hall amount difference may be compared with the calibrated hall amount difference ranges corresponding to the plurality of control positions, respectively, the calibrated hall amount difference range in which the current hall amount difference is located may be determined from the calibrated hall amount difference ranges corresponding to the plurality of control positions, and the calibrated hall amount difference range in which the current hall amount difference is located may be determined as the target calibrated hall amount difference range.

As an example, assume that the calibrated hall difference value ranges corresponding to the respective plurality of control positions include: 62-92, -7-23 and-90-60, wherein the current first Hall amount is 120, the current second Hall amount is 55, the current Hall amount difference is 120-55=65, and 62-92 can be determined from 62-92, -7-23 and-90-60 as a target calibration Hall difference value range.

Step S350: and determining a control position corresponding to the target calibration Hall difference value range from the plurality of control positions as the target control position.

In this embodiment, in the case of determining the target calibration hall difference value range, it is possible to determine the control position corresponding to the target calibration hall difference value range from among the plurality of control positions, and determine the control position corresponding to the target calibration hall difference value range as the target control position.

In some embodiments, in the case of determining the target calibration hall amount difference range, the target control position corresponding to the target calibration hall amount difference range may be determined based on a correspondence relationship between the plurality of control positions and the plurality of calibration hall amount differences, where the plurality of control positions have a one-to-one correspondence relationship with the plurality of calibration hall amount differences.

As an example, assume that the plurality of control positions includes three control positions of up (up), middle (middle), down (down), and that the control position up corresponds to the calibrated hall-difference value range 62 to 92, the control position middle corresponds to the calibrated hall-difference value range-7 to 23, and the control position down corresponds to the calibrated hall-difference value range-90 to-60. If the current first Hall quantity is 120 and the current second Hall quantity is 55, the current Hall quantity difference value is 120-55=65, the target calibration Hall quantity difference value range is 62-92, and the target control position is the control position up.

It can be understood that when the target control position is determined, the target control position is obtained by subtracting two hall amounts, and is not easily influenced by an external magnetic field, in other words, when the external magnetic field of the electronic device is close to the magnet, the external magnetic field can simultaneously generate a hall effect with the first hall sensor and the second hall sensor, so that the difference value of the hall amounts acquired by the first hall sensor and the second hall sensor at the current moment is approximate to the hall difference value acquired when no magnet is interfered at the current moment, even if the external magnetic field is interfered, the target control position can still be accurately determined, and the anti-interference performance is improved.

Compared with the method for determining the key position shown in fig. 6, in the method for determining the key position, in this embodiment, when the interference result is determined that there is no magnet interference, difference calculation is performed on the current first current hall amount and the current second hall amount, a current hall amount difference value is obtained, a calibrated hall difference value range in which the current hall amount difference value is located is determined as a target calibrated hall difference value range from calibrated hall difference value ranges corresponding to a plurality of control positions, wherein the calibrated hall difference value range is determined based on difference values and interference difference margins between calibrated hall amounts acquired by the same control positions of the first hall sensor and the second hall sensor in the plurality of control positions, and a control position corresponding to the target calibrated hall difference value range is determined as a target control position from the plurality of control positions, so that the final target control position can be determined by a difference value calculation mode of double hall sensors under the condition that no interference is determined, and the anti-interference performance of the determined target control position is improved.

Step S430: and if the interference result is that the external magnetic field interference exists, determining an interference form corresponding to the external magnetic field interference, wherein the interference form comprises stable interference or unstable interference.

In this embodiment, if it is determined that the external magnetic field interference exists as a result of the interference, an interference form corresponding to the external magnetic field interference may be determined, where the interference form includes stable interference or unstable interference, that is, it may be determined whether the interfering magnetic interference is stable interference or unstable interference.

In some embodiments, the electronic device may be preset with preset state information corresponding to the stable interference in the interference form, and if it is determined that the external magnetic field interference exists as the interference result, the current state information of the electronic device may be determined, and the current state information may be compared with the preset state information to determine whether the current state information matches the preset state information, if so, the stable interference in the interference form may be determined, and if not, the unstable interference in the interference form may be determined.

Referring to fig. 11, fig. 11 is a flowchart illustrating step S430 of the method for determining a key position shown in fig. 10. The following details about the flow shown in fig. 11, the method may specifically include the following steps:

step S431: and if the interference result is that the external magnetic field interference exists, acquiring a plurality of reference Hall quantities acquired by a reference Hall sensor according to a preset time interval, wherein the reference Hall sensor is the first Hall sensor or the second Hall sensor.

In this embodiment, if it is determined that the interference result is that there is external magnetic field interference, a plurality of reference hall amounts acquired by a reference hall sensor according to a preset time interval may be acquired, where the reference hall sensor may be a first hall sensor hall second hall sensor.

In some embodiments, the first hall sensor or the second hall sensor may be determined as the reference hall sensor at random, or the first hall sensor or the second hall sensor may be determined as the reference hall sensor by polling, or the first hall sensor or the second hall sensor may be determined as the reference hall sensor by fixing, etc., without limitation.

In some embodiments, the electronic device may preset a time interval as a preset time interval, and preset a target number of reference hall amounts required, based on which, in a case that it is determined that the interference result is that there is external magnetic field interference, the reference hall sensor may be controlled to acquire the reference hall amounts according to the preset time interval based on the target number, so as to obtain a plurality of reference hall amounts.

Step S432: and calculating the average value of the reference Hall quantities to obtain the average value of the reference Hall quantities.

In the present embodiment, in the case where a plurality of reference hall amounts are obtained, an average value calculation may be performed on the plurality of reference hall amounts to obtain a reference hall amount average value.

As an embodiment, in the case of obtaining a plurality of reference hall amounts, a sum value may be calculated for the plurality of reference hall amounts to obtain a reference hall amount sum value, and then the reference hall amount sum value is divided by a target number corresponding to the plurality of reference hall amounts to obtain a reference hall amount average value.

As an example, assuming that the plurality of reference hall amounts includes 50, 51, the reference hall amount average value is 50.5.

Step S433: and calculating the difference value between the reference Hall quantity average value and the reference Hall quantity acquired last time to obtain a reference Hall quantity difference value.

In this embodiment, in the case of obtaining the reference hall amount average value, the reference hall amount average value and the reference hall amount obtained last time may be subjected to difference calculation to obtain the reference hall amount difference value. Alternatively, the reference hall amount difference may be an absolute value of a difference between the reference hall amount average value and the reference hall amount acquired last time.

In some embodiments, in the case of obtaining the reference hall quantity average value, the difference value may be calculated by subtracting the reference hall quantity obtained last time from the reference hall quantity average value, to obtain the reference hall quantity difference value; alternatively, the reference hall amount difference may be obtained by subtracting the reference hall amount average value from the reference hall amount obtained last time, which is not limited herein.

In some embodiments, it may be based onAnd calculating the average value of the reference Hall quantity and the reference Hall quantity acquired last time to obtain a reference Hall quantity difference value, wherein diff is the reference Hall quantity difference value.

Step S434: and determining the interference form based on the reference Hall quantity difference value and a stable interference threshold value.

In some embodiments, the electronic device may preset and store a stable interference threshold, where the stable interference threshold is used as a basis for determining the reference hall amount difference. Therefore, in the present embodiment, in the case of obtaining the reference hall amount difference value, the reference hall amount difference value may be compared with the stable interference threshold value to obtain a magnitude relation between the reference hall amount difference value and the stable interference threshold value, and based on the magnitude relation, it is determined whether the interference is in the form of stable interference or unstable interference.

As an implementation manner, if the reference hall quantity difference is smaller than the stable interference threshold, the interference form can be determined to be stable interference; if the reference hall amount difference is equal to or greater than the stable interference threshold, it may be determined that the interference is in the form of unstable interference.

As an example, assume that the plurality of reference hall amounts includes 50, 51, and the stable interference threshold is 1. Then the reference hall quantity average is 50.5, the reference hall quantity difference may be 51-50.5=0.5, and since 0.5 < 1, it may be determined that the interference is in the form of stable interference.

Step S440: if it is determined that the disturbance is in the form of the stable disturbance, the target control position is determined from the plurality of control positions based on the first hall amount and the second hall amount.

In the present embodiment, if it is determined that the external magnetic field interference exists as a result of the interference, the target control position may be determined from the plurality of control positions based on the first hall amount and the second hall amount.

In some embodiments, if it is determined that the disturbance result is that there is an external magnetic field disturbance, a position calculation manner corresponding to the presence of the external magnetic field disturbance may be determined, and the first hall amount and the second hall amount are calculated by the position calculation manner corresponding to the presence of the external magnetic field disturbance, so as to determine the target control position from the plurality of control positions.
