As shown in fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides an intelligent wearable device, including a wearable device 1 and a controller 2, in some embodiments, the wearable device 1 is an intelligent watch or an intelligent bracelet, that is, an intelligent wearable device in the general sense, and is generally worn on a wrist 3 of a user, and the controller 2 is a ring and is worn on a finger 4 of the user; the wearable device 1 comprises a first body 14, a magnetic resistance 12 and a voltage detection device, wherein the magnetic resistance 12 refers to a metal or a semiconductor with a magnetic resistance effect, and the magnetic resistance effect refers to a phenomenon that the resistance value of some metals or semiconductors changes along with the change of an external magnetic field. Like the Hall effect, the magneto-resistive effect is also due to the fact that the carriers are subjected to Lorentz in a magnetic fieldThe force is generated. When the carrier reaches a steady state, the electric field force applied to the carriers at a certain speed is equal to the Lorentz force, the carriers are gathered at two ends to generate a Hall electric field, the carriers slower than the speed deflect towards the electric field force direction, and the carriers faster than the speed deflect towards the Lorentz force direction. This deflection leads to an increased drift path for the carriers. Alternatively, the number of carriers moving in the direction of the applied electric field decreases, thereby increasing the resistance. This phenomenon is called the magnetoresistance effect, and devices with the magnetoresistance effect are called magnetoresistance. The resistivity of magnetoresistive element 12 varies in dependence on the angle between the direction of current in magnetoresistive element 12 and the magnetic field strength, while in a static magnetic field with constant magnetic field strength (e.g. the earth's magnetic field), it varies only in dependence on the angle between the direction of current and the direction of magnetic field; specifically, in the static magnetic field, when the current in magnetoresistance 12 is perpendicular to the direction of the magnetic field, the resistivity of magnetoresistance 12 changes most; when the current in magnetoresistance 12 is parallel to the direction of the magnetic field, there is minimal or no change in the resistivity of magnetoresistance 12. In this embodiment, the magnetic resistance 12 is fixed in the first body 14, a fixed current exists in the magnetic resistance 12, the voltage detection device is configured to detect a voltage across the magnetic resistance 12 and generate corresponding level signal information, and the wearable device 1 searches a corresponding operation command in the preset execution list according to the level signal information and executes a corresponding preset operation; the controller 2 generates a static magnetic field, when the user wears the wearable device 1 and the controller 2, the magnetic resistance 12 is located in the static magnetic field, and the controller 2 is located at a different relative position with the wearable device 1 under the operation of the user, namely, the magnetic field direction of the static magnetic field and the fixed current in the magnetic resistance 12 form different included angles, so that the resistance value of the magnetic resistance 12 is changed, and the voltage at two ends of the magnetic resistance 12 is changed. In this embodiment, the user can interact with the smart wearable device by, for example, the wearable device 1 is a smart watch, the controller 2 is a ring, and in a naturally relaxed state, that is, when the user is not interacting with the smart watch, the finger 4 and the wrist 3 of the user are in the same plane, and at this time, the magnetic induction line in the static magnetic field produced by setting the ring is parallel to the fixed current direction in the magnetic resistance 12, that is, the resistance value of the magnetic resistance 12 is the minimum, because of the large fixed current in the magnetic resistance 12Small and constant, according to ohm's law, the voltage across reluctance 12 is also at a minimum, denoted as Vmin. When a user wears the finger 4 of the ring to bend, namely the user interacts with the smart watch, the finger 4 and the wrist 3 of the user are no longer on the same plane, the direction of the magnetic induction line in the static magnetic field manufactured by the ring is intersected with the direction of the fixed current in the magnetic resistance 12, namely the resistance value of the magnetic resistance 12 is increased, and as the size of the fixed current in the magnetic resistance 12 is not changed, the voltage at two ends of the magnetic resistance 12 is also increased according to ohm's law and is recorded as VDetection ofWherein when the direction of the magnetic sense line is perpendicular to the direction of the fixed current in magnetoresistive element 12, the resistance of magnetoresistive element 12 is maximized, and the voltage across magnetoresistive element 12 is also maximized, denoted as Vmax. Voltage detection means generates corresponding level signal information based on the detected voltage after detecting the voltage across magnetoresistive element 12. In some embodiments, the voltage detection device is in the form of a hardware device and exists in the wearable device, and after the corresponding level signal information is generated, the wearable device can directly search and execute the corresponding operation command in the preset execution list according to the level signal information, and the operation command is directly and conveniently searched and executed without being processed by a central CPU of the wearable device. In other embodiments, the voltage detection device is implemented by software programming, and further includes a CPU, where after the CPU obtains the level signal information generated by the voltage detection device, the CPU searches for a corresponding operation command in a preset execution list, then sends out the searched operation command, and finally the wearable device 1 executes the operation command. In some embodiments, a preset voltage threshold is preset, when the voltage detection device detects that the voltage across the magnetic resistance 12 is smaller than the preset voltage threshold, for example, when the finger 4 and the wrist 3 are on the same plane, the generated level signal information is a low level signal, and when the wearable device 1 obtains the low level signal, the corresponding operation command found in the preset execution list is no operation, it is determined that the user is not interacting with the smart watch, and at this time, no operation is taken. When the voltage detection device detects that the voltage at the two ends of the magnetic resistance 12 is greater than the preset voltage threshold value, the generated level signal information is a high level signal, and the wearable device 1 considers that the user sends out and makes sense when acquiring the high level signalIf the watch can perform an interactive instruction, performing a preset operation according to an operation command found in the preset execution list, for example, if the level signal information acquired by the smart watch in the screen-off state or the dormant state is a high level signal, the smart watch may turn on the screen for the user to check or operate. For another example, if the level signal information acquired by the smart watch in the bright screen state is a high level signal, information viewing or other operations can be performed, and the smart watch receives a level signal information containing the high level signal, which is similar to a conventional control instruction generated by pressing a button on an external key of the smart watch. Through the above setting, the user can realize the functions of lighting the screen 11 of the smart watch or checking the information received on the smart watch by bending the finger 4 once. In some embodiments, when two or more high-level signals occur continuously, different level signal information may be formed, the CPU performs different operations according to the number of high-level signals included in the received level signal information, that is, different operations are similar to a difference between a single click and a double click of a mouse, or similar to an instruction issued by an earphone key in the prior art, for example, when a user plays music through a smart watch, a finger 4 wearing the controller 2 bends once to issue a high-level signal to form level signal information, and when the wearable device 1 acquires the level signal information, the playing of the music is suspended according to a found operation command; continuously bending the two lower fingers 4, namely continuously sending out two high-level signals to form level signal information containing the two high-level signals, and when the wearable device 1 obtains the level signal information, switching to the next curve according to the searched operation command; the three fingers 4 are continuously bent, that is, the three high-level signals are continuously sent out, so that level signal information including the three high-level signals is formed, and when the wearable device 1 acquires the level signal information, the operation is switched to the previous bending according to the searched operation command. In other embodiments, two different preset voltage thresholds V are preset1And V2Is provided with Vmin＜V1＜V2＜VmaxCorrespondingly, the voltage detection means can also generate signals of a plurality of different levels, for example when the user is only slightly satisfiedWhen the finger 4 is slightly bent, the angle between the magnetic induction line of the static magnetic field and the current in the magnetic resistance 12 is small, the change of the resistance value of the magnetic resistance 12 is also small, and the voltage detection device detects the voltage V on the two sides of the magnetic resistance 12 at the momentDetection ofIs of size V1＜VDetection of＜V2The voltage detection device generates a first level signal to form level signal information containing the first level signal, and the wearable device 1 searches for a corresponding operation command in a preset execution list and executes corresponding preset operation after acquiring the level signal information. When the bending degree of the user's finger 4 is large or the user makes a fist, the angle between the magnetic induction line of the static magnetic field and the current in the magnetic resistance 12 is large, the change of the resistance value of the magnetic resistance 12 is also large, and the voltage detection device detects the voltage V at the two sides of the magnetic resistance 12 at this timeDetection ofIs of size V2＜VDetection of≤VmaxThe voltage detection device generates a second level signal to form level signal information including the second level signal, and the wearable device 1 searches for a corresponding operation command in the preset execution list and executes a corresponding preset operation after acquiring the level signal information. Namely, the method is equivalent to no longer simply distinguishing the high-level signal from the low-level signal, but can identify a plurality of different-size level signals and obtain corresponding operation commands according to the different-size level signals, wherein the second level signal is equivalent to the first level signal which is the high-level signal. For example, when the user bends the finger 4 slightly, the wearable device 1 finds an instruction for determining an option in the preset execution list after acquiring the level signal information including the first level signal, for example, entering viewing information, and when the user makes a fist, the wearable device 1 finds a backward instruction in the preset execution list after acquiring the level signal information including the second level signal, for example, exiting viewing information, and the user can realize an interaction process for entering the option or exiting the option with the smart watch by slightly bending the finger 4 and making a fist. In other embodiments, more than two preset voltage thresholds can be set, and accordingly, the voltage detection device can also generate various level signals, so that the interactive content is richer and more diverse.
At one endIn some embodiments, the level signal information recognized by the wearable device 1 includes not only the level signal, i.e., the high-low level signal, but also the level signal duration, i.e., the long signal or the short signal. The wearing device 1 further comprises a timing device which is always at a timing moment and serves as a timing reference. The timing device is in communication connection with the CPU, when the CPU detects that the level signal changes, for example, the level signal changes from a low level signal to a high level signal, the CPU obtains a first timing moment of the timing device, when the level signal changes again, namely, the level signal changes from the high level signal to the low level signal or changes to a higher high level signal, the CPU obtains a second timing moment of the timing device and calculates a time difference between the first timing moment and the second timing moment, wherein the time difference is the level signal duration of the high level signal, and finally the CPU integrates the level signal and the level signal duration to search a corresponding operation command in a preset execution list and executes the operation command. In some embodiments, the preset time threshold is set to T in advance1The duration of the level signal is T2When T is detected2≤T1When the signal level is detected, the CPU determines that the signal level is a short signal, similar to a conventional short-press key, and detects T2＞T1When the key is pressed, the CPU judges the level signal as a long signal, similar to the conventional long key press, and the CPU depends on the duration T of the level signal2For example, after the finger slightly bends or makes a fist, the normal state that the finger and the wrist are in the same plane is recovered, and at this time, the CPU detects the duration T of the level signal2≤T1If the CPU judges that the level signal is a short signal, the CPU executes normal interactive operation such as forward or backward movement according to the level signal, and the user still keeps the state of bending or making a fist after slightly bending the fingers or making the fist, so that the fingers are continuously contacted with the palm for a period of time, and the CPU detects the duration T of the level signal2＞T1The CPU determines the level signal as a long signal based on the level signalAnd the number executes interactive operations such as calling out a menu or turning off the machine. According to time detection, level signals are divided into long signals and short signals, so that interactive operation contents between a user and intelligent equipment are richer and more diverse, and operability is stronger.
As shown in fig. 2, in some embodiments, the wearable device 1 further includes a screen 11 and a gyroscope 13, the screen 11 and the gyroscope 13 are respectively in communication connection with the CPU, the gyroscope 13 is configured to detect an angle between the screen 11 and a horizontal plane and notify the angle to the CPU, and when the gyroscope 13 detects that the screen 11 and the horizontal plane are within a set angle range, the CPU starts the voltage detection device according to a detection result of the gyroscope 13. The gyroscope 13 is arranged to detect the included angle between the screen 11 and the horizontal plane, so as to prevent the generation of misoperation, and in some embodiments, the voltage detection device is started only when the gyroscope 13 detects that the screen 11 and the horizontal plane are within the set included angle range. When general people want to look over the information in the intelligent wrist-watch, lift up wrist 3 after the contained angle between wrist-watch screen 11 and the horizontal plane is less, when the screen 11 that detects the intelligent wrist-watch through the angle faces the people's face promptly, voltage detection device just can start, and when people hang down wrist 3 or be in the walking state, the contained angle between wrist-watch screen 11 and the horizontal plane is great, then does not start voltage detection device this moment. Through setting up gyroscope 13, intelligence wearing equipment can be in the user information of wanting to look over, just start voltage detection device when preparing to carry out interactive operation, has both reduced the possibility that takes place the maloperation when user's walking or other states, has improved the convenience that user's operation used again.
In some embodiments, the number of the controllers 2 is plural. In order to improve the richness of interactive operation contents between a user and the intelligent wearable device, a plurality of controllers 2 can be arranged and respectively worn on different fingers 4, the operation interactive principle is the same as that of only one controller 2, different included angles are formed between the current direction in the magnetic resistance 12 and the magnetic induction line direction of the magnetic field by moving the controller 2 so as to change the resistance value of the magnetic resistance 12 and further change the voltage at two ends of the magnetic resistance 12, thus the level signal information generated by the voltage detection device is different, the corresponding operation commands are also different, only when a plurality of controllers 2 are arranged, the magnetic field strength of the static magnetic field formed by the controller is different from that of the single controller 2, the adjustable range of the magnetic field strength is larger when the plurality of controllers 2 are arranged, for example, when only one controller 2 is moved and a plurality of controllers 2 are moved simultaneously, the magnetic field strengths are different, the larger the range corresponding to the voltage across the magnetic resistance 12, the more abundant the content of the level signal information generated by the voltage detection device. In some embodiments, the static magnetic field intensity of each controller 2 is set to be the same, and the interaction commands sent by moving only one controller 2 (bending one finger 4) are different from the interaction commands sent by moving two controllers 2 simultaneously (bending two fingers 4 simultaneously) or moving multiple controllers 2 simultaneously (bending multiple fingers 4 simultaneously), for example, when only bending the index finger to move one controller 2, the interaction command sent correspondingly is an operation for the intelligent wearable device to determine the current display, and when bending the index finger and the middle finger simultaneously and moving two controllers 2 simultaneously, the interaction command sent correspondingly is an operation for the intelligent wearable device to cancel the current display. In other embodiments, the static magnetic field intensity of each controller 2 is set to be different, and the corresponding issued interaction instruction is also different, for example, when only the controller 2 worn by the index finger is bent to move, the corresponding issued interaction instruction is an operation for the intelligent wearable device to determine the current display, and when only the controller 2 worn by the middle finger is bent to move, the corresponding issued interaction instruction is an operation for the intelligent wearable device to cancel the current display. Through setting up a plurality of controllers 2 for the interactive operation content between user and the intelligent wearing equipment is abundanter, has further improved interactive maneuverability.
In some embodiments, the controller 2 includes a camera communicatively coupled to the CPU. Because intelligent wearing equipment does not have the function of shooing generally, even there is the function of shooing moreover, because the restriction of its position of wearing, it is very inconvenient to use. A camera is arranged in the controller 2 for shooting, and then the shot image is transmitted to the screen 11 of the wearable device 1 in a wireless transmission mode for displaying. Because controller 2 wears on user's finger 4, it uses the intelligent wearing equipment of shooing function more easily to operate, and because its volume is less, can also shoot through stretching into some narrow regions with finger 4, enlarges the range of application who shoots. Through set up the camera in controller 2, improved intelligent wearing equipment's functionality greatly, made the user possess better operation experience.
The invention provides intelligent wearable equipment, which comprises wearable equipment 1 and a controller 2; the wearable device 1 comprises a first body 14, wherein a magnetic resistance 12 and a voltage detection device are arranged in the first body 14, a fixed current flows in the magnetic resistance 12, and the voltage detection device is used for detecting the voltage at two ends of the magnetic resistance 12; the controller 2 includes a second body; the second body is capable of generating a static magnetic field; when the user wears the wearable device 1 and the controller 2, the magnetic resistance 12 is located in the static magnetic field, the voltage detection device detects the voltage at two ends of the magnetic resistance 12 and generates corresponding level signal information, the wearable device 1 searches for corresponding operation commands in the preset execution list according to the level signal information and executes the operation commands, different instructions are sent to the wearable device 1 through the mobile controller 2, the purpose that the user can carry out rich-content human-computer interaction with the intelligent wearable device is achieved, the interaction process is very convenient and fast, and the operability is strong.
The invention also provides an operation method of the intelligent wearable device, which is applied to the intelligent wearable device and comprises the following steps:
s1: acquiring level signal information;
s2: searching an operation command corresponding to the level signal information in a preset execution list;
s3: and executing the operation command.
In the step S1 of obtaining the level signal information, in some embodiments, the wearable device is a smart watch or a smart bracelet, that is, a smart wearable device in a general sense, and is generally worn on a wrist of the user, and the controller is a ring and is worn on a finger of the user; the wearable device comprises a first body, a magnetic resistance and a voltage detection device, wherein the magnetic resistance refers to a metal or a semiconductor with a magnetic resistance effect, and the magnetic resistance effect refers to a phenomenon that the resistance value of some metals or semiconductors changes along with the change of an external magnetic field. Like the Hall effect, the magneto-resistive effect is also due to the Lorentz force that carriers experience in a magnetic fieldAnd then produced. When the carrier reaches a steady state, the electric field force applied to the carriers at a certain speed is equal to the Lorentz force, the carriers are gathered at two ends to generate a Hall electric field, the carriers slower than the speed deflect towards the electric field force direction, and the carriers faster than the speed deflect towards the Lorentz force direction. This deflection leads to an increased drift path for the carriers. Alternatively, the number of carriers moving in the direction of the applied electric field decreases, thereby increasing the resistance. This phenomenon is called the magnetoresistance effect, and devices with the magnetoresistance effect are called magnetoresistance. The change of the resistivity of the magnetic resistance is related to the included angle of the current direction in the magnetic resistance and the direction of the magnetic field and the magnetic field intensity, and is only related to the included angle of the current direction and the magnetic field direction in a static magnetic field (such as an earth magnetic field) with constant magnetic field intensity; specifically, in a static magnetic field, when a current in a magnetoresistance is perpendicular to a magnetic field direction, a resistivity of the magnetoresistance changes most; when the current in the magnetoresistance is parallel to the direction of the magnetic field, there is minimal or no change in the resistivity of the magnetoresistance. In this embodiment, the magnetic resistance is fixed in the first body, a fixed current exists in the magnetic resistance, the voltage detection device is configured to detect voltages at two ends of the magnetic resistance and generate corresponding level signal information, and the wearable device searches a corresponding operation command in the preset execution list according to the level signal information and executes a corresponding preset operation; the controller can produce the static magnetic field, and when the user wore wearing equipment and controller, wearing equipment was located the static magnetic field, and the controller is located different relative position with wearing equipment under user's operation, makes the magnetic field direction of static magnetic field and the fixed current in the magnetic resistance form different contained angles promptly, makes the resistance value of magnetic resistance change to make the voltage at magnetic resistance both ends change. In this embodiment, the user may implement the purpose of interacting with the smart wearable device by, for example, the wearable device is a smart watch, the controller is a ring, and in a naturally relaxed state, that is, when the user is not interacting with the smart watch, the finger and the wrist of the user are on the same plane, at this time, the magnetic induction line in the static magnetic field manufactured by the ring is set to be parallel to the fixed current direction in the magnetic resistance, that is, the resistance value of the magnetic resistance is minimum, and since the fixed current in the magnetic resistance is not changed, according to ohm's law, at this time, the magnetic induction line is parallel to the fixed current directionThe voltage across the resistor is also minimal, denoted as Vmin. When the finger that the user wore the ring was crooked, namely when the user interacted with the intelligent wrist-watch, user's finger and wrist were no longer in the coplanar, and the direction of the fixed current in the direction of the magnetic induction line in the static magnetic field that the ring was made was crossing with the direction in the magnetic resistance this moment, and the resistance value of magnetic resistance becomes promptly, because the size of fixed current in the magnetic resistance does not change, according to ohm's law, the voltage at magnetic resistance both ends also becomes this moment, marks as VDetection ofWherein when the direction of the magnetic induction line is perpendicular to the direction of the fixed current in the magnetic resistance, the resistance value of the magnetic resistance is maximum, and the voltage across the magnetic resistance is also maximum at this time, which is denoted as Vmax. The voltage detection device generates corresponding level signal information according to the detected voltage after detecting the voltage at two ends of the magnetic resistance.
In the step S2 of searching the operation command corresponding to the level signal information in the preset execution list, in some embodiments, the voltage detection device exists in the wearable device in the form of a hardware device, and after the corresponding level signal information is generated, the wearable device can directly search the corresponding operation command in the preset execution list according to the level signal information and execute the operation command, without processing by a central CPU of the wearable device, which is directly convenient. In other embodiments, the voltage detection device is implemented by software programming, and further includes a CPU, where after the CPU obtains the level signal information generated by the voltage detection device, the CPU searches for a corresponding operation command in a preset execution list, then sends out the searched operation command, and finally the wearable device executes the operation command. In some embodiments, a preset voltage threshold is preset, and when the voltage detection device detects that the voltage across the magnetic resistance is smaller than the preset voltage threshold, for example, when the finger and the wrist are on the same plane, the generated level signal information is a low level signal. When the voltage detection device detects that the voltage at the two ends of the magnetic resistance is greater than the preset voltage threshold value, the generated level signal information is a high level signal. In other embodiments, more than two preset voltage thresholds can be set, and accordingly, the voltage detection device can also generate various level signals, so that the interactive content is richer and more diverse.
In the step S3 of executing the operation command, in some embodiments, when the wearable device obtains the low level signal, the corresponding operation command found in the preset execution list is no operation, and it is determined that the user is not interacting with the smart watch, and no operation is taken at this time. When the wearable device obtains the high-level signal, the wearable device considers that the user sends an instruction for interacting with the smart watch, and then performs preset operation according to the operation command found in the preset execution list, for example, if the level signal information obtained by the smart watch in the screen-off state or the dormant state is the high-level signal, the smart watch is turned on for the user to check or operate. For another example, if the level signal information acquired by the smart watch in the bright screen state is a high level signal, information viewing or other operations can be performed, and the smart watch receives a level signal information containing the high level signal, which is similar to a conventional control instruction generated by pressing a button on an external key of the smart watch. Through the above setting, the user can realize the functions of lighting the screen of the intelligent watch or checking the information received on the intelligent watch by bending the finger once. In some embodiments, when two or more high-level signals occur continuously, different level signal information is formed, the CPU performs different operations according to the number of high-level signals included in the received level signal information, that is, a difference similar to a single click or a double click of a mouse, or an instruction similar to an instruction issued by an earphone key in the prior art, for example, when a user plays music through a smart watch, a finger wearing a controller bends to issue a high-level signal once to form level signal information, and when the wearable device acquires the level signal information, the wearable device pauses playing music according to a found operation command; continuously bending the two lower fingers, namely continuously sending out two high-level signals to form level signal information containing the two high-level signals, and when the wearable equipment acquires the level signal information, switching to the next curve according to the searched operation command; three fingers continuously bend, namely three high-level signals are continuously sent out to form level signal information containing the three high-level signals, and the wearable equipment acquires the level signal informationAnd when the music is played, switching to the previous music according to the searched operation command. In other embodiments, two different preset voltage thresholds V are preset1And V2Is provided with Vmin＜V1＜V2＜VmaxCorrespondingly, the voltage detection device can also generate a plurality of different level signals, for example, when a user only slightly bends a finger, the included angle between the magnetic induction line of the static magnetic field and the current in the magnetic resistance is small, the resistance value change of the magnetic resistance is also small, and the voltage detection device detects the voltage V on two sides of the magnetic resistanceDetection ofIs of size V1＜VDetection of＜V2The voltage detection device generates a first level signal to form level signal information containing the first level signal, and the wearable device searches for a corresponding operation command in a preset execution list and executes corresponding preset operation after acquiring the level signal information. When the bending degree of the fingers of the user is large or the user makes a fist, the included angle between the magnetic induction line of the static magnetic field and the current in the magnetic resistance is large, the resistance value change of the magnetic resistance is large, and the voltage V of two sides of the magnetic resistance is detected by the voltage detection deviceDetection ofIs of size V2＜VDetection of≤VmaxThe voltage detection device generates a second level signal to form level signal information containing the second level signal, and the wearable device searches for a corresponding operation command in a preset execution list and executes corresponding preset operation after acquiring the level signal information. Namely, the method is equivalent to no longer simply distinguishing the high-level signal from the low-level signal, but can identify a plurality of different-size level signals and obtain corresponding operation commands according to the different-size level signals, wherein the second level signal is equivalent to the first level signal which is the high-level signal. For example, when the user bends the finger slightly, the wearable device finds an instruction of determining an option in the preset execution list after acquiring the level signal information containing the first level signal, such as entering the viewing information, and when the user makes a fist, the wearable device finds a backward instruction in the preset execution list after acquiring the level signal information containing the second level signal, such as exiting the viewing information, and the user bends the finger slightly and makes a fist by a combination of slightlyAn interactive process of entering an option or exiting an option can be implemented with the smart watch.
In some embodiments, before the step S1 of acquiring the level signal information, the method further includes:
s01: detecting an included angle between the screen and a horizontal plane;
s02: and if the included angle is within the range of the set included angle, entering a step of acquiring level signal information.
In the step S01 of detecting the angle between the screen and the horizontal plane, in some embodiments, the wearable device further includes a screen and a gyroscope, the gyroscope is in communication connection with the CPU, and the gyroscope is used for detecting the angle between the screen and the horizontal plane and notifying the angle to the CPU.
If the angle is within the range of the set angle, the step S02 of detecting the voltages at the two ends of the magnetic resistance is performed, and when the gyroscope detects that the screen and the horizontal plane are within the range of the set angle, the CPU starts the voltage detection device according to the detection result of the gyroscope. The setting of the included angle between the gyroscope detection screen and the horizontal plane is to prevent the generation of misoperation, and in some embodiments, the voltage detection device is started only when the gyroscope detects that the screen and the horizontal plane are within the set included angle range. When general people want to look over the information in the intelligent wrist-watch, the contained angle between wrist-watch screen and the horizontal plane is less after lifting up the wrist, when the screen that detects intelligent wrist-watch through the angle promptly faces the people's face, voltage detection device just can start, and just can produce level signal information and let wearing equipment acquire, and when people hang down or be in the walking state to the wrist, the contained angle between wrist-watch screen and the horizontal plane is great, then does not start voltage detection device this moment. Through setting up the gyroscope, intelligence wearing equipment can be in the user information of wanting to look over, just start voltage detection device when preparing to carry out interactive operation, has both reduced the possibility that takes place the maloperation when user's walking or other states, has improved the convenience that user's operation used again.
In some embodiments, the step S1 of obtaining the level signal information further includes:
s11: acquiring a level signal and the level signal duration of the level signal;
s12: and forming the level signal and the corresponding level signal duration into level signal information.

The wearable device further comprises a timing device, and the timing device is always in a timing moment and used as a timing reference. The timing device is in communication connection with the CPU, when the CPU detects that the level signal changes, for example, the level signal changes from a low level signal to a high level signal, the CPU obtains a first timing time of the timing device, when the level signal changes again, namely, the level signal changes from the high level signal to the low level signal or changes to a higher high level signal, the CPU obtains a second timing time of the timing device and calculates a time difference value between the first timing time and the second timing time, wherein the time difference value is the level signal duration of the high level signal.
In the step S12 of forming the level signal and the corresponding level signal duration into the level signal information, in some embodiments, the preset time threshold is set in advance to T1The duration of the level signal is T2When T is detected2≤T1When the signal level is detected, the CPU determines that the signal level is a short signal, similar to a conventional short-press key, and detects T2＞T1When the key is pressed, the CPU judges the level signal as a long signal, similar to the conventional long key press, and the CPU depends on the duration T of the level signal2The difference is that different operation commands are found in the preset execution list, specifically, for example, after the user slightly bends the finger or makes a fist, the normal state that the finger and the wrist are in the same plane is recovered after the finger contacts the palm, and the CPU detects the duration T of the level signal2≤T1The CPU judges the level signal as a short signal, combines the short signal with the level signal to form level signal information, and then generates a level signal information according to the level signal informationThe flat signal information executes normal interactive operation such as forward or backward movement, and the user still keeps the state of bending the fingers or making a fist after bending the fingers or making a fist slightly, so that the fingers are continuously contacted with the palm for a period of time, and the CPU detects the duration T of the level signal2＞T1The CPU judges the level signal as a long signal, combines the long signal with the level signal to form level signal information, and then executes interactive operations such as menu calling or shutdown according to the level signal information. According to time detection, level signals are divided into long signals and short signals, so that interactive operation contents between a user and intelligent equipment are richer and more diverse, and operability is stronger.
In some embodiments, the step S1 of obtaining the level signal information further includes:
s13: acquiring the change frequency and amplitude of the level signal within preset time;
s14: the varying frequency and amplitude are taken as level signal information.
In the above step S13 of acquiring the variation frequency and amplitude of the level signal within the preset time, in some embodiments, when two or more high level signals continuously appear (i.e., the high level signal and the low level signal appear alternately and quickly), the CPU takes different actions according to the number of the high level signals received in a short time, that is, different operation commands are found in the preset execution list by the variation frequency and amplitude of the level signal detected within the preset time. In some embodiments, the preset time for detecting the frequency and amplitude of the level signal change is 1 s.
In the step S14 where the variation frequency and amplitude are used as the level signal information, the CPU performs different operations according to the number of high level signals received in a short time, that is, the operation is similar to the difference between a single click and a double click of a mouse, or similar to an instruction issued by an earphone key in the prior art, for example, when a user plays music through a smart watch, the front half part of a finger wearing a controller contacts a palm (which is equivalent to bending the finger) to issue a high level signal, so as to form level signal information, and when receiving the level signal information, the CPU stops playing the music according to the found operation instruction; the front half part of the finger is continuously contacted with the palm for two times, namely two high level signals are continuously sent out to form level signal information containing the two high level signals, and when the CPU receives the level signal information, the CPU is switched to the next song according to the searched operation command; and when the CPU receives the level signal information, the CPU switches to the previous song according to the searched operation command.
