Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic structural diagram of an intelligent wearable device according to an embodiment of the present invention.
As shown in fig. 1, the intelligent wearable device comprises a housing 10, wherein a rotating shaft hole 11 is formed in the housing 10; a rotating shaft 12 penetrates through the rotating shaft hole 11, and a magnet 13 with opposite magnetism is fixedly arranged at one end of the rotating shaft 12 positioned in the shell 10; the housing 10 is also provided therein with a magnetic sensor 14 corresponding to the suspension of the magnet 13 having opposite magnetism, and a control circuit 15 electrically connected to the magnetic sensor 14.
Wherein, there may be a certain diameter difference between the outer diameter of the rotation shaft 12 and the inner diameter of the rotation shaft hole 11 to ensure the normal rotation of the rotation shaft 12 while preventing particles in the air from entering the inside of the housing 10.
Alternatively, one or more pairs of magnets of opposite magnetic properties may be provided at the end of the rotatable shaft 12 within the housing 10. When a plurality of pairs of magnets of opposite magnetic properties are secured, each pair of magnets of opposite magnetic properties is oppositely secured to the rotating shaft 12, and the magnetic properties of adjacent magnets of opposite magnetic properties are opposite. The magnet 13 having opposite magnetism generates a change in magnetic field as the rotary shaft 12 rotates, and the magnetic sensor 14 outputs a level signal according to the change in magnetic field. Further, the control circuit 15 can recognize the rotation direction of the rotation shaft based on the level signal.
In embodiments of the present invention, the sensitivity of the rotation direction detection can be adjusted by adjusting the logarithm of the magnets on the rotation shaft 12 that are opposite in magnetism. When the rotating shaft 12 is connected with a pair of magnets with opposite magnetism, the minimum rotation radian required for judging the rotation direction is min (alpha, pi-alpha), namely, the rotating shaft only needs to rotate by a min (alpha, pi-alpha) angle, and the control circuit 15 can determine the rotation direction; where α is the phase difference of the level signals output from the control circuit 15. When the rotating shaft 12 is connected with N pairs of magnets with opposite magnetism, the minimum rotating radian required for judging the rotating direction is min (alpha, pi-alpha)/N; wherein N is a positive integer. The more the number of magnet pairs, the higher the sensitivity of the magnetic sensor 14 to detect changes in magnetic field, and the particular number may depend on the control sensitivity requirements of the smart wearable device.
Alternatively, the magnetic sensor 14 comprises two magnetic sensing sub-modules, a first magnetic sensing sub-module and a second magnetic sensing sub-module. In order to ensure that a level signal can be generated according to the magnetic field change generated when the magnet 13 with opposite magnetism rotates along the rotating shaft 12, the first magnetic sensing sub-module and the second magnetic sensing sub-module are oppositely arranged in the shell 10, and the connecting direction of the first magnetic sensing sub-module and the second magnetic sensing sub-module cannot be consistent with the direction of the rotating shaft 12. Preferably, the direction of the connection line of the first magnetic sensing sub-module and the second magnetic sensing sub-module can be parallel to a certain tangential direction when the rotating shaft 12 rotates, and further, the first magnetic sensing sub-module and the second magnetic sensing sub-module can detect magnetic field change at the position with the most obvious magnetic field change, so that a foundation is laid for improving the direction detection efficiency of the control circuit 15.
Alternatively, as shown in fig. 1b, the first and second magnetic sensing sub-modules may output level signals generated according to magnetic field changes through the first and second output pins 141 and 142 in the magnetic sensor 14, respectively. Because the connecting line direction of the first magnetic sensing sub-module and the second magnetic sensing sub-module is not parallel to the rotating shaft 12, and a certain distance exists between the first magnetic sensing sub-module and the second magnetic sensing sub-module, a certain phase difference exists between signals of level signals output by the first magnetic sensing sub-module and the second magnetic sensing sub-module.
Optionally, as shown in fig. 1b, the control circuit 15 comprises a first input pin 151 and a second input pin 152. When the magnetic sensor 14 is electrically connected to the control circuit 15, the first output pin 141 is connected to the first input pin 151, and the second output pin 142 is connected to the second input pin 152.
After the control circuit 15 receives the level signals output by the magnetic sensor 14 through the first output pin 141 and the second output pin 142 through the first input pin 151 and the second input pin 152, it can further identify the rotation mode of the rotation shaft 13 in the rotation operation according to the level signals and perform operation control on the smart wearable device according to the rotation mode of the rotation shaft 13 in the rotation operation.
Optionally, a rotating head 16 is fixed at one end of the rotating shaft 13 located outside the housing 10, and it is more convenient to rotate the rotating shaft 13 through the rotating head 16. The rotary head 16 and the rotary shaft 13 may be provided in combination or integrally. When assembled, the swivel head 16 may be a cap-like structure mounted on the swivel shaft 13.
The intelligent wearing equipment that this embodiment provided has offered a pivot hole on intelligent wearing equipment's shell, has a rotation axis to wear to locate this pivot hole. One end of the rotating shaft positioned in the shell is fixedly provided with a magnet with opposite magnetism; and a magnetic sensor corresponding to the magnetic body with opposite magnetism is suspended in the shell. The magnetic sensor may sense a change in magnetic field when the magnet having the opposite magnetic property rotates along with the rotation shaft to output a level signal. Below the magnetic sensor, a control circuit is provided to which the magnetic sensor is electrically connected. The control circuit can identify the rotation mode of the rotating shaft in rotation operation according to the level signal output by the magnetic sensor and perform operation control on the intelligent wearable device according to the rotation mode. The intelligent wearing equipment that this embodiment provided, accessible simple structure realizes the complicated operation control to intelligent wearing equipment, has solved among the prior art, intelligent wearing equipment switch structure complicacy, occupation space great defect, is favorable to intelligent wearing equipment's miniaturization.
It should be noted that, the smart device provided by the present invention includes, but is not limited to, wearable devices such as smart watches, smart bracelets, smart glasses, smart clothes, and the like, and will not be described herein.
Fig. 2 is a flowchart of a method for controlling an intelligent wearable device according to an embodiment of the present invention. The control method is used for controlling the intelligent wearable device corresponding to the figure 1. As shown in fig. 2, the control method includes:
step 201, receiving a level signal output by the magnetic sensor according to the magnetic field change when the magnet with opposite magnetism rotates along with the rotating shaft.
Step 202, according to the level signal output by the magnetic sensor, the rotation mode of the rotating shaft in the rotation operation is identified.
And 203, performing operation control on the intelligent wearable device according to the rotation mode of the rotation shaft in the rotation operation.
For step 201, the rotation of the rotation axis is initiated when the user wants to control the smart wearable device, and the user can rotate through the rotator head on the rotation axis. When the rotating shaft rotates, the magnet with opposite magnetism fixedly arranged on the rotating shaft also rotates along with the rotating shaft, so that the magnetic field nearby the magnetic sensor is changed. After the magnetic sensor detects the magnetic field change, the magnetic field change can be converted into a level signal and the level signal can be output.
In step 202, if the level signal output from the magnetic sensor changes, it can be determined that the magnetic field near the magnetic sensor changes, that is, that the magnet fixed on the rotation shaft and having opposite magnetism has a rotation operation. Further, the rotation mode of the rotating shaft in the rotation operation can be identified by analyzing the level signal.
Alternatively, the rotation manner of the rotation shaft in the rotation operation may be embodied by the direction in which the rotation shaft rotates in sequence in the rotation operation and the number of successive rotations in each direction. Wherein, the combination between different rotation directions and the combination between different continuous rotation times in each rotation direction can generate different rotation modes. For example, rotating 3 times in a clockwise direction is one way of rotation; the rotation is carried out for 2 times continuously in the clockwise direction and 2 times continuously in the anticlockwise direction, and the rotation belongs to another rotation mode; the rotation in the clockwise direction is 1 time, and the rotation in the anticlockwise direction is 3 times, and the method belongs to another rotation mode.
Wherein the direction of rotation includes a clockwise direction or a counterclockwise direction. The number of successive rotations in each direction, i.e. the number of successive rotations with the direction unchanged.
For the continuous rotation times, from the angle of the control circuit, the continuous rotation times are times when the control circuit continuously detects signal jump corresponding to the same rotation direction; for example, after 1 signal transition corresponding to the clockwise direction is detected, 3 signal transitions corresponding to the clockwise direction are continuously detected, and it is determined that the number of rotations of the rotation shaft in the clockwise direction is 4 in the rotation operation. The number of rotations is the number of minimum angles in which the rotation direction can be detected, included in the total rotation angles of the continuous rotations, from the viewpoint of the rotation axis; for example, the control circuit can detect that the minimum angle of the rotation direction is 30 °, and if the rotation shaft is rotated continuously in the counterclockwise direction by 90 °, it can be determined that the rotation number of rotations of the rotation shaft in the counterclockwise direction is 3 times in the rotation operation.
For step 203, after determining the rotation manner of the rotation shaft in the rotation operation, the operation type corresponding to the rotation operation may be determined according to the rotation-based manner.
Alternatively, the operation types corresponding to the rotation operation may include, but are not limited to: a wake-up type, a volume up/down type, a page forward/backward type, a photo/video type, or a quick on/off mute type, each of which identifies a control operation for the smart wearable device.
Alternatively, the correspondence relationship between the rotation manner and the operation type corresponding to the rotation operation may be preset. For example, the clockwise direction rotates 2 times continuously, and the counterclockwise direction rotates 2 times continuously, corresponding to the wake-up type; continuously rotating for 3 times in the clockwise direction, and corresponding to the volume increment type; the clockwise rotation 1 time corresponds to the type of page flip after, and so on. Based on this, after determining the rotation manner of the rotation shaft in the rotation operation, the correspondence relationship may be queried, and the operation type corresponding to the determined rotation manner may be determined.
After determining the operation type corresponding to the rotation operation, the operation control identified by the operation type can be performed on the intelligent wearable device. For example, when the operation type is determined to be a wake type, the smart wearable device in the standby state may be awakened. For example, when the operation type is determined to be a volume up/down type, the play volume of the smart wearable device may be increased/decreased. For another example, when the operation type is determined to be the front/back page turning type, the content currently displayed by the intelligent wearable device may be turned.
According to the intelligent wearable device control method, after receiving the level signal output by the magnetic sensor according to the magnetic field change when the magnet with opposite magnetism rotates along with the rotating shaft, the rotating mode of the rotating shaft in the rotating operation is identified according to the level signal output by the magnetic sensor, and the intelligent wearable device is operated and controlled based on the rotating mode of the rotating shaft in the rotating operation. And then under intelligent wearing equipment simple structure's prerequisite, realize the complicated operation control to intelligent wearing equipment through the discernment to rotatory mode, solved among the prior art, intelligent wearing equipment switch structure is complicated, occupation space is great defect, is favorable to intelligent wearing equipment's miniaturization.
Fig. 3 is a flowchart of another intelligent wearable device control method according to an embodiment of the present invention. The control method is used for controlling the intelligent wearable device corresponding to the figure 1. As shown in fig. 3, the control method includes:
step 301, receiving a level signal output by the magnetic sensor according to the magnetic field change when the magnet with opposite magnetism rotates along with the rotating shaft.
Step 302, according to the level signal output by the magnetic sensor, the direction in which the rotation shaft rotates in turn in the rotation operation and the number of continuous rotations in each rotation direction are identified.
Step 303, determining a corresponding operation type according to the direction in which the rotation shaft rotates in turn in the rotation operation and the continuous rotation times in each rotation direction.
Step 304, performing operation control identified by the operation type on the intelligent wearable device.
For step 301, optionally, in order to analyze the rotation direction of the rotation shaft, a magnetic sensor is provided that is composed of a first magnetic sensing sub-module and a second magnetic sensing sub-module. The first magnetic sensing sub-module outputs a level signal through a first output pin of the magnetic sensor, and the second magnetic sensing sub-module outputs a level signal through a second output pin of the magnetic sensor.
Preferably, the connecting line direction of the first magnetic sensing sub-module and the second magnetic sensing sub-module is parallel to a tangential line direction when the rotating shaft rotates. Further, the first magnetic sensor sub-module and the second magnetic sensor sub-module can detect a magnetic field change at a position where the magnetic field change is most noticeable when the magnet having opposite magnetism rotates along with the rotation axis.
In this embodiment, the first magnetic sensor sub-module points in the direction of the second magnetic sensor sub-module, and coincides with the tangential direction when the rotation axis rotates clockwise. In the following steps, the method for determining the rotation direction is described on the premise that the method is not described in detail.
Alternatively, in this embodiment, the magnetic sensor may be a hall sensor capable of outputting a square wave level signal according to a magnetic field change, and accordingly, the hall sensor includes a first hall detection sub-module and a second hall detection sub-module.
Optionally, for step 302, identifying a rotation mode of the rotation shaft in the rotation operation according to the level signal output by the magnetic sensor includes identifying a direction in which the rotation shaft rotates in sequence in the rotation operation and a number of consecutive rotations in each rotation direction according to the level signal output by the magnetic sensor.
Alternatively, identifying the direction in which the rotation shafts sequentially rotate in the rotation operation may be achieved by: firstly, when signal jump is detected, detecting an output pin with signal jump in a first output pin and a second output pin of a magnetic sensor; and secondly, the current rotation direction of the rotating shaft in the rotation operation can be identified according to the level difference of the level signal output by the output pin generating the signal jump and the other output pin.
Optionally, if the output pin where the signal jump occurs is the first output pin corresponding to the first magnetic sensing submodule, and the level difference between the level signals output by the first output pin and the level signals output by the second output pin is zero, determining that the current rotation direction of the rotating shaft is in a counterclockwise direction at the moment when the signal jump occurs; and if the level difference between the first output pin and the second output pin is not zero, determining that the current rotation direction of the rotating shaft is clockwise at the moment when the signal jump occurs.
If the output pin with the signal jump is a second output pin corresponding to the second magnetic sensing sub-module and the level difference between the level signals output by the second output pin and the level signals output by the first output pin is zero, determining that the current rotation direction of the rotating shaft is clockwise at the moment of the signal jump; and if the level difference of the level signals output by the second output pin and the first output pin is not zero, determining that the current rotation direction of the rotating shaft is anticlockwise at the moment when the signal jump occurs.
Alternatively, identifying the number of successive rotations of the rotary shaft in each rotation direction of the rotary operation may be achieved by: and recording the number of continuous signal jump in the current rotation direction as the rotation number in the current rotation direction. For example, when a signal transition is detected for the first time, it is determined that the rotation direction of the rotation shaft at the time of the signal transition is clockwise, and the number of rotations in the clockwise direction is recorded as 1. If the signal jump is detected for the second time, the direction of the rotating shaft is judged to be clockwise when the signal jump is detected, and the number of times of rotation in the clockwise direction is recorded to be 2. If the rotation direction of the rotation shaft is counterclockwise when the signal jump is detected for the third time and the rotation direction of the rotation shaft is clockwise when the signal jump is detected for the fourth time, the number of times of counting is repeated in the clockwise direction, namely, the number of times of rotation in the clockwise direction is recorded as 1.
For step 303, optionally, the direction in which the rotation shaft rotates in turn in the rotation operation and the correspondence of the number of successive rotations in each rotation direction to the operation type are pre-configured in the control circuit. After the rotation operation is detected, the operation type corresponding to the rotation operation can be determined by inquiring the corresponding relation according to the direction of sequential rotation in the rotation operation and the continuous rotation times in each rotation direction.
Optionally, if the detected rotation operation in the standby state includes at least one rotation in a clockwise direction and at least one rotation in a counterclockwise direction, it may be determined that the operation type corresponding to the rotation operation is a wake-up type.
In an optional embodiment, if a rotation operation is detected in the wake-up state, the operation type corresponding to the rotation operation may be determined to be a volume up/down type, a front/back page turning type, a photo/video recording type, or a fast on/off mute type according to a direction of sequential rotation in the rotation operation and a number of continuous rotations in each rotation direction.
For example, if the rotation mode of the rotation shaft during the rotation operation is one rotation in the clockwise direction, it may be determined that the operation type corresponding to the rotation operation is the volume increasing type; the rotation mode of the rotation shaft in the rotation operation process is counterclockwise rotation once, and the operation type corresponding to the rotation operation can be determined as the volume reduction type.
For example, if the rotation mode of the rotation shaft in the rotation operation process is clockwise two times of continuous rotation, the operation type corresponding to the rotation operation can be determined to be a front page turning type; the rotation mode of the rotation shaft in the rotation operation process is that the rotation shaft rotates anticlockwise twice continuously, and the operation type corresponding to the rotation operation can be determined to be the page-turning-back type.
For example, if the rotation mode of the rotation shaft in the rotation operation process is that the rotation shaft rotates three times clockwise continuously, the operation type corresponding to the rotation operation can be determined to be a photographing type; the rotation mode of the rotation shaft in the rotation operation process is that the rotation shaft rotates anticlockwise three times continuously, and the operation type corresponding to the rotation operation can be determined to be a video type.
For another example, if the rotation mode of the rotation shaft in the rotation operation process is clockwise four times of continuous rotation, the operation type corresponding to the rotation operation can be determined to be a quick opening mute type; the rotation mode of the rotating shaft in the process of the rotation operation is anticlockwise continuous rotation four times, and the operation type corresponding to the rotation operation can be determined to be a quick closing mute type.
Of course, the correspondence between the rotation mode and the operation type of the rotation shaft in the rotation operation process is only used for example, and the technical solution of the embodiment of the present invention is not limited. In the actual control process, the corresponding relation between the rotation mode and the operation type can be set by user definition.
In this embodiment, the above-mentioned determination of the operation type corresponding to the rotation operation according to the direction of the sequential rotation in the rotation operation and the number of continuous rotations in each rotation direction may be applied to application scenarios with multiple control requirements. For example, the application scenario of the multiple control requirements may be: a user reads news through a news client installed on the intelligent wearing equipment while playing background music through a music player installed on the intelligent wearing equipment; in this scenario, the user needs to turn a page of the content displayed by the news client, and also needs to control the playing volume of the music player. For example, the application scenario of the multiple control requirements may also be: in the process of reading the mail or the short message, the content of the mail or the short message needs to be subjected to screen capturing; in this scenario, the user needs to perform page-turning control on the content displayed by the mail or the short message, and needs to perform photographing control on the intelligent wearable device.
In another optional embodiment, when the control method of the intelligent wearable device is applied to an application scene with a single control requirement, the volume up/down type, front/back page turning type, photographing/video recording type or quick opening/closing mute type corresponding to the rotating operation can be determined directly according to the direction of sequential rotation in the rotating operation. Wherein each specific operation type is associated with an application currently running on the smart wearable device.
For example, in the process that a user uses a multimedia application program such as audio and video playing or a radio provided by the intelligent wearable device, if a rotation operation of the rotation axis clockwise is detected, an operation type corresponding to the rotation operation is a volume increasing type; if a rotation operation of the rotation shaft counterclockwise is detected, the operation type corresponding to the rotation operation is a volume reduction type.
For example, in the process that a user uses an address book, a mail, a short message, a map or other application programs needing to be read provided by the intelligent wearable device, if a rotation operation of a rotation shaft clockwise is detected, an operation type corresponding to the rotation operation is a front page turning type; if the rotation operation of the rotation shaft anticlockwise is detected, the operation type corresponding to the rotation operation is a page-backward type.
For example, in a process that a user uses a camera provided by the intelligent wearable device, if a rotation operation of the rotation shaft clockwise is detected, an operation type corresponding to the rotation operation is a photographing type; if a rotation operation of the rotation shaft anticlockwise is detected, the operation type corresponding to the rotation operation is a video recording type.
For another example, when the intelligent wearable device receives a reminding bell, if a rotation operation of the rotating shaft clockwise is detected, an operation type corresponding to the rotation operation is a silence closing type; if the rotation operation of the rotation shaft anticlockwise is detected, the operation type corresponding to the rotation operation is a mute-on type.
For step 304, each operation type described in the previous step may identify an operation control, for example, the wake type identifies the smart wearable device in the wake standby state; the volume up/down type identifier controls the volume of the intelligent wearable device; the front/back page turning type identifier performs page turning operation on the content displayed by the intelligent wearable equipment; the photographing/video recording type identifier captures a screen of content displayed by the intelligent wearing equipment or photographs the content through a camera of the intelligent wearing equipment; the quick on/off mute type identifier quickly turns on or off a telephone ring when the smart wearable device receives a telephone request or quickly turns off or turns on a reminder ring when the smart wearable device alarm clock receives other message reminders.
Optionally, when the method is applied to an application scene with a single control requirement, if the rotation operation of the rotating shaft in the clockwise direction is detected and the volume increase type corresponding to the rotation operation is determined, the volume increase amplitude can be determined according to the continuous rotation times of the rotating shaft in the clockwise direction; and increasing the playing volume of the intelligent wearable device according to the volume increasing amplitude. If the rotation operation of the rotating shaft in the anticlockwise direction is detected and the volume reduction type corresponding to the rotation operation is determined, determining the volume reduction amplitude according to the continuous rotation times of the rotating shaft in the anticlockwise direction; and according to the volume reduction amplitude, reducing the playing volume of the intelligent wearable device.
Wherein, the corresponding relation between the rotation direction and the volume increase or decrease, and the corresponding volume adjustment amplitude of each rotation are preconfigured in the control circuit. For example, rotating clockwise corresponds to an increase in volume and rotating counterclockwise corresponds to a decrease in volume. For example, the sound volume is increased by 10DB once in a clockwise direction and the sound volume is decreased by 10DB once in a counterclockwise direction.
Optionally, when the method is applied to an application scene with a single control requirement, if a rotation operation of the rotating shaft in a clockwise direction is detected and the front page turning type corresponding to the rotation operation is determined, the page turning number can be determined according to the continuous rotation times of the rotating shaft in the clockwise direction; and forward page turning is carried out on the content displayed by the intelligent wearable equipment according to the page turning number. If the rotation operation of the rotating shaft in the anticlockwise direction is detected and the type of the backward page turning corresponding to the rotation operation is determined, the page turning number can be determined according to the continuous rotation times of the rotating shaft in the anticlockwise direction; and performing backward page turning on the content displayed by the intelligent wearable equipment according to the page turning number.
The corresponding relation between the rotation direction and the front page turning or the back page turning and the page turning number corresponding to each rotation are also preconfigured in the control circuit. For example, rotating one time clockwise corresponds to back page turning and rotating one time counterclockwise corresponds to front page turning. It should be noted that, in the embodiment, the "forward page turning or backward page turning" may be up-down page turning or left-right page turning, which is not limited by the embodiment of the present invention.

And then under intelligent wearing equipment simple structure's prerequisite, realize the complicated operation control to intelligent wearing equipment through the discernment to rotatory mode, solved among the prior art, intelligent wearing equipment switch structure is complicated, occupation space is great defect, is favorable to intelligent wearing equipment's miniaturization.
Fig. 4 is a flowchart of another control method of an intelligent wearable device according to an embodiment of the present invention. The control method is used for controlling the intelligent wearable device corresponding to the figure 1. As shown in fig. 4, the control method includes:
step 401, receiving a level signal output by the magnetic sensor according to a magnetic field change when the magnet with opposite magnetism rotates along with the rotating shaft.
Step 402, according to the level signal output by the magnetic sensor, the direction of the rotation shaft rotating in turn in the rotation operation is identified.
Step 403, if the intelligent wearable device is in a standby state, and the rotation axis sequentially rotates in a clockwise direction to a counterclockwise direction or from the counterclockwise direction to the clockwise direction in a rotation operation within a preset period, and the rotation times in the clockwise direction and the counterclockwise direction are set times, determining that the operation type is a wake-up type.
Step 404, performing wake-up control on the intelligent wearable device.
The specific embodiments of step 401 and step 402 may refer to the descriptions in the examples of fig. 2 and 3, and are not repeated here.
For step 403, the preset duration may be 5 seconds or 3 seconds of initialization, or may be user-defined. The direction of rotation within the preset period of time is changed from the clockwise direction to the counterclockwise direction, or from the counterclockwise direction to the clockwise direction, i.e., the rotation operation in which the direction of the rotation shaft is changed. The number of times can be initialized to at least one time or can be set by user definition.
In an alternative embodiment, the wake-up type is rotated at least once in a clockwise direction and then at least once in a counter-clockwise direction within 5 seconds, or rotated once in a counter-clockwise direction and then in a clockwise direction. That is, when the smart wearable device is in the standby state, if a rotation operation in which the occurrence direction of the rotation shaft is changed is once detected within 5 seconds, it may be determined that the operation type is a wake-up operation. In this embodiment, the number of times the rotation shaft rotates in each direction is not limited, and the operation type may be determined to be the wake-up type as long as a change in the rotation direction is detected. For example, after the rotation shaft rotates once in the clockwise direction within 5 seconds and rotates once in the counterclockwise direction, the operation type may be determined to be the wake-up type.
In another alternative embodiment, the rotation mode corresponding to the wake type may be customized by the user. For example, the user a sets the rotation mode corresponding to the wake-up type to rotate 3 times counterclockwise after rotating at least once clockwise within 3 seconds. For example, the B user sets the rotation mode corresponding to the wake-up type to rotate 3 times in the clockwise direction within 5 seconds, and then rotate 3 times in the counterclockwise direction. In the embodiment, the user can set the rotation mode of the intelligent wearing equipment in the personalized wake-up standby state, so that the privacy security in the personal intelligent wearing equipment can be protected. In addition, the user limits the rotation times in each direction, so that the trouble caused by misoperation can be well avoided, and the user experience is further improved.
According to the intelligent wearable device control method, after receiving the level signal output by the magnetic sensor according to the magnetic field change when the magnet with opposite magnetism rotates along with the rotating shaft, the rotating direction of the rotating shaft in the rotating operation is identified according to the level signal output by the magnetic sensor. When the intelligent wearable device is in a standby state, the corresponding wake-up type of the rotation operation can be determined based on the change of the rotation direction in the preset time, and then the intelligent wearable device is waken up. Therefore, under the condition that the intelligent wearable device does not have a wake-up button, the wake-up control function is realized through the combined use of the rotary switch function, so that the intelligent wearable device structure can be simpler. According to the technical scheme, the defects that in the prior art, the switch structure of the intelligent wearing equipment is complex and the occupied space is large are overcome, miniaturization of the intelligent wearing equipment is facilitated, and user experience is improved.
