Based on the above hardware structure, various embodiments of the electronic pen control method of the present invention are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of an electronic pen control method.
A first embodiment of the present invention provides an electronic pen control method, including the steps of:
with the rapid development of science and technology, various electronic devices are increasingly widely applied to daily life of people. For example, an active electronic pen applied to a touch screen device such as a tablet computer generally determines a user intention by presetting various sensors such as a pressure sensor and an acceleration sensor in hardware, and then switches an operation state inside the electronic pen. However, the mode of judging the practical intention of the user only by the sensor often has a misjudgment situation, for example, if the acceleration sensor is preset in the active electronic pen, if the user puts the electronic pen on a backpack, the backpack shakes up and down when walking, the acceleration sensor misjudgment is caused, and the working mode of the active electronic pen is started; or the pressure sensor is preset in the active electronic pen and is extruded by other articles in the backpack, so that misjudgment of the pressure sensor can be caused, and the working mode is started. Both of the above two situations cause unnecessary power consumption of the electronic pen, thereby causing a technical problem of false triggering of the working mode of the electronic pen.
In order to solve the problems, the invention preliminarily judges the use intention of the user on the electronic pen by detecting the acceleration data, further judges the use intention of the user on the electronic pen by analyzing the change rate of the acceleration in the acceleration data, thereby adjusting the dormant state of the electronic pen, converting the dormant state into the working state with normal energy consumption so as to start more functions, more accurately judging the use intention of the user, avoiding unnecessary consumption of electric quantity caused by misjudging the use intention of the user, prolonging the service life of the electronic pen and finally solving the technical problem of mistriggering of the working mode of the electronic pen. The invention is applied to the electronic pen.
Step S10, when the electronic pen is in a dormant state, detecting acceleration data of the electronic pen;
the acceleration sensor may be a change rate of acceleration, an angular change amount of acceleration, a change rate of the angular change amount of acceleration, or the like.
In this embodiment, an acceleration sensor may be preset in the electronic pen, and acceleration data may be obtained through the acceleration sensor, and the number of the preset sensors is not limited in this embodiment. If the current electronic pen is set to be the active capacitive pen, the capacitive pen is in a dormant state. When a user directly or indirectly initiates an operation which can be sensed by an acceleration sensor in the capacitive pen to the capacitive pen, the acceleration sensor senses the current action of the user, detects the current acceleration data and sends the current acceleration data to a main control module in the capacitive pen. And the main control module receives the acceleration data sent by the acceleration sensor, and can preliminarily judge that the user has the current use intention. It is understood that the power switch of the capacitive stylus is turned on before step S10. In addition, in addition to the acceleration sensor, other types of sensors such as a pressure sensor may be preset in the capacitive pen to further detect the user's intention. And each power consumption state of the capacitive pen can be defined as different power consumption levels, for example, the sleep state is defined as a first power consumption level, and the working state is defined as a second power consumption level. Specifically, a user firstly presses a power switch key on the capacitance pen, a bistable control circuit in the capacitance pen detects state switching of the power switch key, current output is switched to another stable state, and a field effect transistor MOSFET of the power switch is driven to electrify an acceleration sensor, a booster circuit and a main control circuit in the capacitance pen so as to complete startup operation. After the capacitive pen is started, the capacitive pen is in an energy-saving state, and the main control circuit detects the state of the acceleration sensor at any time. When the user picks up the capacitance pen, the acceleration sensor senses the current action of the user and acquires the current acceleration change rate.
Step S20, judging whether the acceleration change rate of the electronic pen is larger than a preset first threshold value according to the acceleration data;
the preset first threshold is a critical value used for determining the current use intention of the user according to the acceleration change rate, and is set based on the preset use habit of the user, and can be flexibly set according to the actual situation, which is not specifically limited in this embodiment.
In this embodiment, since the acceleration data sensed by the current acceleration sensor may be generated by a user's misoperation, such as a user placing a pen in a bag and shaking the pen to cause movement of the pen, the user's intention of use needs to be further confirmed to eliminate the misoperation. And the preset acceleration sensor sends the current acceleration change rate to the main control circuit. When the main control circuit receives the acceleration change rate, the main control circuit compares the acceleration change rate with a preset first threshold value.
Step S30, if the acceleration rate is greater than the preset first threshold, switching the electronic pen from the sleep state to the working state.
In this embodiment, if the main control circuit in the capacitive pen determines that the change rate of the acceleration sent by the acceleration sensor is greater than the preset first threshold, it may be determined that the user currently needs to use the capacitive pen, adjust the current energy consumption state, and switch the sleep mode in which the capacitive pen is located to the standard working mode; and if the acceleration change rate is judged to be less than or equal to the preset first threshold value, the current dormant state is not changed. In addition, the use intention of the user can be further judged according to other numerical values in the acceleration data or whether a code printing signal sent by the touch screen device is detected.
The invention provides an electronic pen control method. The electronic pen control method detects acceleration data of an electronic pen when the electronic pen is in a dormant state; judging whether the acceleration change rate of the electronic pen is greater than a preset first threshold value or not according to the acceleration data; and if the acceleration change rate is greater than the preset first threshold value, switching the electronic pen from the dormant state to the working state. Through the mode, the electronic pen using intention of the user is preliminarily judged by detecting the acceleration data, the electronic pen using intention of the user is further judged by analyzing the acceleration change rate in the acceleration data, so that the sleep state of the electronic pen is adjusted and converted into the normal energy-consuming working state to start more functions, the user using intention of the user can be judged more accurately, unnecessary consumption of electric quantity caused by misjudgment of the user using intention is avoided, the using time of the electronic pen is prolonged, and the technical problem that the working mode of the electronic pen is triggered by mistake is finally solved.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for controlling an electronic pen according to a second embodiment of the present invention.
Based on the first embodiment shown in fig. 2 described above, in the present embodiment, step S20 includes:
step S21, if the acceleration rate is greater than the preset first threshold, determining whether an angle variation in the acceleration data is greater than a preset second threshold;
the preset second threshold is a critical value used for further determining the current use intention of the user according to the angle variation, and is set based on the preset use habit of the user, and can be flexibly set according to the actual situation, which is not specifically limited by the embodiment.
In this embodiment, the capacitive stylus is currently in a sleep state. If the main control circuit in the capacitive pen judges that the acceleration change rate is larger than a first threshold preset according to the use habit of the user, whether the angle change amount of the acceleration in the acceleration data is larger than a preset second threshold is further judged.
Step S22, if the angle variation is greater than a preset second threshold, switching the electronic pen from the sleep state to a working state;
in this embodiment, if the main control circuit in the capacitive pen determines that the acceleration angle variation in the acceleration data is greater than the preset second threshold, it may be determined that the current user has an intention to use the capacitive pen, so that the sleep state at this time is switched to the standard working state for the user to use the capacitive pen normally.
Step S23, if the angle variation is not greater than the preset second threshold, not changing the current sleep state of the electronic pen.
In this embodiment, if the main control circuit in the capacitive pen determines that the acceleration angle variation in the acceleration data is less than or equal to the preset second threshold, the current situation may be that the user puts the capacitive pen in a bag and shakes the capacitive pen during walking, rather than a scenario that the user takes the pen to prepare for writing, so that it may be determined that the current user does not have an intention to use the capacitive pen, based on maintaining the current sleep state.
Further, not shown in the figure, in the present embodiment, the step S22 includes:
step a, if the angle variation is larger than the preset second threshold, judging whether the variation rate of the angle variation in the acceleration data is larger than a preset third threshold;
the preset third threshold is a critical value for further determining the current use intention of the user according to the change rate of the angle change amount, and is set based on the preset use habit of the user, and can be flexibly set according to the actual situation, which is not specifically limited in this embodiment.
In this embodiment, if the capacitive pen determines that the angle variation in the current acceleration data is greater than the preset second threshold, the change rate of the angle variation in the acceleration data is further determined, and the value of the change rate is compared with a preset third threshold based on the use habit of the user, so as to further confirm the use intention of the user and avoid the situation that the user opens the working state of the capacitive pen due to misoperation.
B, if the change rate is larger than the preset third threshold, switching the electronic pen from the dormant state to a working state;
in this embodiment, if the main control circuit in the capacitive pen determines that the change rate of the angle change in the acceleration data is greater than the preset third threshold, it may be determined that the user currently has an intention to use the capacitive pen, and the current sleep mode is switched to the operating state, so that the user can use the capacitive pen normally.
And c, if the change rate is not greater than the preset third threshold, not changing the current sleep state of the electronic pen.
In this embodiment, if the main control circuit in the capacitive pen determines that the change rate of the angle change in the acceleration data is less than or equal to the preset third threshold, it may be determined that the user does not currently have an intention to use the capacitive pen, and the current acceleration generation cause may be caused by a user's misoperation, so that the current sleep state of the capacitive pen is continuously maintained.
The invention provides an electronic pen control method. The electronic pen control method further confirms the current use intention of the user by judging whether the angle variation is larger than a preset second threshold value, so that the misjudgment rate of switching the electronic pen from a non-working state to a working state is reduced; the current use intention of the user is further confirmed by judging whether the change rate of the angle change is greater than a preset third threshold value, so that the condition that the user triggers the working state of the electronic pen by mistake is avoided to the greatest extent, and the service life of the electronic pen is prolonged.
Not shown in the drawings, a third embodiment of the electronic pen control method according to the present invention is provided based on the first embodiment shown in fig. 2. In the present embodiment, step S20 includes:
step d, if the acceleration rate of change in the acceleration data is greater than the preset first threshold, starting a code printing signal detection path in the electronic pen, and judging whether a code printing signal is detected;
the code printing signal is a specific signal used for matching and sent out outwards when the touch screen equipment such as a flat plate is in a working state.
In this embodiment, if the main control circuit in the capacitive pen determines that the acceleration change rate in the current acceleration data is greater than the preset first threshold, a code printing signal detection path for detecting a screen end code printing signal sent by the touch screen device, such as a tablet, in a normal working state is opened, so as to further determine whether the current user brings the capacitive pen close to the touch screen device.
Step e, if the code printing signal is detected, switching the electronic pen from the dormant state to a working state;
in this embodiment, if the main control circuit of the capacitive pen currently detects a screen end code printing signal sent by the touch screen device in the operating state, it may be determined that the user currently brings the capacitive pen close to the touch screen device, that is, it is determined that the user currently has an intention to use the capacitive pen, so that the capacitive pen is switched from the current sleep state to the operating state, so that the user can use the capacitive pen conveniently.
And f, if the code printing signal is not detected, not changing the current sleep state of the electronic pen.
In this embodiment, if the main control circuit of the capacitive pen does not detect a screen end code printing signal sent by the touch screen device in the operating state, it may be determined that the user does not approach the capacitive pen to the touch screen device currently, that is, it is determined that the user does not have an intention to use the capacitive pen currently, so that the current sleep mode is continuously maintained to reduce unnecessary energy consumption.
Further, in this embodiment, step S20 includes:
step g, if the code printing signal is detected, acquiring a current power consumption parameter based on the code printing signal;
in this embodiment, after the capacitive pen detects a screen end code printing signal sent by the tablet, an instruction for acquiring the current power consumption parameter is triggered. The main control circuit obtains the power consumption grade corresponding to the current operation scene. Wherein, the power consumption level is used for describing the power consumption level of the operation scene in the device. The power consumption parameters may include performance parameters and behavior parameters. And the main control circuit matches the acquired current behavior parameters and current performance parameters with the standard behavior parameters and the standard performance parameters corresponding to the preset energy consumption levels to determine the power consumption level of the current internal operation state of the capacitive pen.
And h, determining that the current power consumption state is the dormant state according to the current power consumption parameters, and switching the electronic pen from the dormant state to a working state.
In this embodiment, after matching the current behavior parameter and the current performance parameter with the standard behavior parameter and the standard performance parameter corresponding to each preset power consumption level, the main control circuit determines that the current power consumption state of the capacitive pen is the sleep state corresponding to the first power consumption level, and switches the sleep state to the standard working state corresponding to the second power consumption level, so that the user can use the function of the electronic pen normally.
Further, in this embodiment, after step S20, the method further includes:
step i, judging whether the code printing signal is detected within a preset first time length or not;
the preset first duration is a time threshold for triggering whether the capacitive pen performs state switching based on the code printing signal in the working state, and the specific duration value can be flexibly set according to the actual situation, which is not limited in this embodiment.
In this embodiment, at this time, the capacitive pen is in the standard operating state, and in order to further reduce unnecessary energy consumption, a first duration is preset, and it is determined whether a code printing signal sent by another device is received within the first duration after the capacitive pen is switched to the standard operating state.
Step j, if the code printing signal is not detected within the preset first time period, switching the electronic pen from the working state to the dormant state, and closing the code printing signal detection path;
in this embodiment, within a preset first time period after the capacitive pen is in the standard working state, if the code printing signal sent by the tablet is not detected, the standard working state is switched to the sleep state. Specifically. The preset first time duration is set to be twenty minutes, if a user does not contact the capacitive pen with the flat plate in the working state within twenty minutes after the capacitive pen is in the standard working state, namely, the user fails to receive a screen end code printing signal sent by the flat plate, a main control circuit in the capacitive pen switches the current standard working state to the dormant state, and closes a specific channel for detecting the code printing signal, so that energy consumption during the period when the user is not in use is reduced.
And k, if the code printing signal is detected within the preset first duration, the current working state of the electronic pen is not changed.
In this embodiment, within a preset second time period after the capacitive pen is in the standard working state, if a screen end code printing signal sent by the tablet is detected, it can be determined that the capacitive pen still needs to be used by the current user, so that the current standard working state is continuously maintained for normal use by the user.
Further, in this embodiment, after step j, the method further includes:
step l, judging whether the acceleration data is detected within a preset second time length;
the preset second time length is a time threshold used for judging whether the capacitive pen is in a sleep state after the preset first time length, and the specific time length value can be flexibly set according to the actual situation, which is not limited in this embodiment.
In this embodiment, it can be understood that the capacitive pen is switched to the sleep state because the capacitive pen does not receive the code printing signal within the preset first time period, and at this time, the path for detecting the code printing signal is closed. In order to further reduce unnecessary energy consumption, a second time duration is preset, and whether the acceleration data sent by the acceleration sensor is received or not is continuously judged within a third time duration after the capacitive pen is switched from the standard working state to the dormant state.
Step m, if the acceleration data is not detected within the preset second duration, switching the electronic pen from the dormant state to a power-off state;
in this embodiment, within a preset second time period after the capacitive pen is in the sleep state, if acceleration data sent by the acceleration sensor is not detected, it can be determined that the current user does not have an intention to use the capacitive pen, and the current sleep state is switched to the power-off state, so that energy consumption is reduced to the maximum extent.
And n, if the acceleration data are detected within the preset second time length, repeating the steps, and judging whether the acceleration change rate of the electronic pen is greater than a preset first threshold value or not according to the acceleration data.
In this embodiment, within a preset second time period after the capacitive pen is in the sleep state, if the acceleration data sent by the acceleration sensor is detected, the execution scenario of step S10 is satisfied, and step S20 and the subsequent operations are repeatedly executed.
The invention provides an electronic pen control method. The electronic pen control method further controls the opening and closing of a channel for detecting the coding signal based on the acceleration change rate, so that the electronic pen can more accurately determine whether the current user has the intention of using the device, and the standard working mode is started when the user needs to use the electronic pen at present, thereby avoiding unnecessary energy consumption caused by the fact that the user mistakenly touches the electronic pen to start the working state in advance; determining the power consumption grade through the power consumption parameters, so that the equipment can accurately judge the current power consumption condition; when the electronic pen is controlled to be switched from the standard working state to the dormant state and the power-off state by presetting the first time length and the code printing signal as well as the second time length and the acceleration data, and unnecessary power consumption is further reduced.
