Detailed Description
The present application is described in further detail below in connection with specific examples, but is not intended to be limiting. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.
In a first aspect, an embodiment of the present application provides a smart pen control method, and fig. 1 shows a flowchart of an embodiment of the smart pen control method of the present application.
Referring to fig. 1, the smart pen control method according to the embodiment of the present application includes: receiving a first induction signal; sending a first wireless charging suspension instruction which is used for stopping charging of the intelligent pen; sending a pairing request instruction, wherein the pairing request instruction is used for sending pairing information by the stylus holder; pairing information is received.
In the method for controlling the intelligent pen, when the first sensing signal is received, a first wireless charging suspension instruction for stopping charging of the intelligent pen can be sent, and a pairing request instruction can also be sent, wherein the pairing request instruction is used for sending pairing information by the stylus holder. The smart pen may receive the pairing information. Upon receiving the pairing information, pairing may be achieved. The intelligent pen control method can enable pairing of intelligent pens to be more convenient.
In this embodiment, when the smart pen and the pen holder approach to a certain distance, the smart pen and the pen holder can sense each other. When the intelligent pen senses the pen holder, one end of the intelligent pen can generate a first sensing signal. When the first sensing signal is received, one end of the intelligent pen can stop charging. The smart pen may send a pairing request instruction to the pen holder. At this time, the pen holder is a receiving end for the intelligent pen pairing. The pen holder responds to the pairing request instruction and can return pairing information. When pairing information returned by the pen holder is received, the intelligent pen can realize pairing. According to the intelligent pen control method, when the intelligent pen approaches the pen holder (receiving end) to a certain distance (communication can be achieved), automatic pairing is achieved, and the intelligent pen control method is more convenient and intelligent.
In an alternative embodiment of the present application, sending the pairing request instruction includes: and sending pairing request instructions at intervals. In this embodiment of the present application, the interval sending pairing request instruction may be sending the pairing request instruction according to a preset time interval. For example, the time interval between two adjacent pairing requests is 1s. Of course, the above-described time interval is not limited, and may be, for example, 500 ms. In this embodiment, one end of the smart pen waits for receiving pairing information returned by the pen stand in a transmission interval for transmitting a pairing request instruction. And when the pairing information is not received in the transmission interval, the pairing request instruction is transmitted again. For example, the pairing request command is transmitted at every second transmission, and the pairing information is waited for to be received in the next second transmission interval after the pairing request command is transmitted. The embodiment can reduce the running energy consumption of the intelligent pen by sending the pairing request instructions at intervals.
FIG. 2 illustrates a flow chart of another embodiment of a smart pen control method of the present application. Referring to the figure, in an alternative embodiment of the present application, when a stop condition is satisfied, the transmission of the pairing request is stopped.
For example, referring to fig. 2, when the pairing information is received, the transmission of the pairing request instruction is stopped. The smart pen receives the pairing request, and can realize pairing. Therefore, upon receiving the pairing information, the transmission of the pairing request instruction may be stopped.
Alternatively, the stop condition may be that the number of times the pairing request command is transmitted reaches a threshold value. For example, referring to fig. 2, when the number of times of sending the pairing request instruction reaches a threshold value and pairing information is not received, sending the pairing request instruction is stopped. In this embodiment, when the number of times of transmitting the pairing request instruction reaches the threshold value in the case where the pairing information is not received, the transmission of the pairing request instruction may be stopped. The problem of infinitely transmitting pairing request instructions due to failure to receive pairing information for some reason is avoided. The threshold value can be set according to different situations. For example, the threshold may be 3 times, 5 times, 8 times, etc.
In connection with the above embodiment, referring to fig. 2, when any one of the following stop conditions is satisfied, the transmission of the pairing request instruction is stopped. One is when pairing information is received. And secondly, when the number of times of sending the pairing request command reaches a threshold value.
Referring to fig. 2, the smart pen control method provided in the embodiment of the present application further includes, after receiving the pairing information: a first charging start instruction is sent, and the first charging start instruction is used for indicating the intelligent pen to start charging; and sending a second charging starting instruction which is used for starting the charging of the stylus holder.
In this embodiment, after receiving the pairing information, the smart pen initiates charging. For example, the smart pen may be triggered to initiate charging by sending a first charge initiation command. And a second charging start instruction is also sent, and the second charging start instruction is used for starting charging of the stylus holder. When the pen holder receives the second charging starting instruction, the charging function of one end of the pen holder can be started. Based on the above, the intelligent pen receives the power from the pen holder to charge. The embodiment can start charging after the intelligent pen is paired, so that automatic pairing and automatic charging are realized, and the performance of the pen is improved.
Referring to fig. 2, in the smart pen control method provided in the embodiment of the present application, when the number of times of sending the pairing request instruction reaches the threshold value and pairing information is not received,
a first charging start instruction is sent, and the first charging start instruction is used for indicating the intelligent pen to start charging; and sending a second charging starting instruction which is used for starting the charging of the stylus holder.
The above-described embodiment has explained that when the number of times of transmitting the pairing request instruction reaches the threshold value and the pairing information is not received, the transmission of the pairing request instruction is stopped. The description about the threshold value and the like will not be repeated. In this embodiment, when the number of times of sending the pairing request instruction reaches a threshold (for example, may be 3 times, 5 times, etc.), and the pairing information is not received, a first charging start instruction for indicating to start charging of the smart pen may be sent, and one end of the smart pen starts a charging function. A second charge initiation command may also be sent, the second charge initiation command being for initiating charging of the stylus holder. When the pen holder receives the second charging starting instruction, the charging function of one end of the pen holder can be started. Based on the above, the intelligent pen receives the power from the pen holder to charge. According to the embodiment, the charging can be forcedly started under the condition that the intelligent pen can not successfully receive the pairing information for many times, so that the applicability of the intelligent pen is improved.
In a second aspect, embodiments of the present application further provide a smart pen that may implement the smart pen control method of the above embodiments, where the above embodiments of the smart pen control method may be used to understand and describe the following embodiments of the smart pen.
FIG. 3 shows a schematic structural diagram of an embodiment of the smart pen of the present application. Referring to fig. 3, the smart pen 10 of the embodiment of the present application includes:

the first main control unit 12 receives the pairing information through the wireless charge receiving unit 11.
In the smart pen 10 provided in the embodiment of the present application, the wireless charging receiving unit 11 is capable of generating the first sensing signal. For example, when the smart pen 10 approaches the pen holder to a certain distance, the wireless charging receiving unit 11 of the smart pen 10 can mutually sense with the wireless charging transmitting unit at one end of the pen holder, so as to generate a first sensing signal at the wireless charging receiving unit 11. The first sensing signal may be generated based on a magnetic flux change, and the first main control unit 12 may transmit a first wireless charging suspension instruction when receiving the first sensing signal, and the first wireless charging control unit 13 stops the smart pen charging when receiving the first wireless charging suspension instruction. The first main control unit 12 may also transmit a pairing request instruction for the stylus holder to transmit pairing information through the wireless charging reception unit 11. The first main control unit 12 may receive pairing information returned from the pen holder through the wireless charging reception unit 11. Pairing can be achieved by the smart pen 10 receiving the pairing information. The intelligent pen of this application embodiment pairs more nimble, convenient.
In the present embodiment, the wireless charge receiving unit 11 is not particularly limited. For example, may include a wireless charging receiving coil. When the smart pen approaches or is inserted into the pen holder, the magnetic flux of the wireless charging receiving coil as the wireless charging receiving unit 11 changes, and a first induction signal is generated. When the first main control unit 12 receives the first sensing signal, it may send a first wireless charging suspension instruction to the first wireless charging control unit 13. For example, the first main control unit 12 sends a low-level control signal to the first wireless charging control unit 13, and the first wireless charging control unit 13 stops the charging operation of the smart pen terminal. The first main control unit 12 may also transmit a pairing request instruction through the wireless charging reception unit 11. When the first main electric control unit 12 receives pairing information returned by the pen holder based on the pairing request instruction through the wireless charging receiving unit 11, pairing can be achieved.
In an alternative embodiment of the present application, the first main control unit 12 transmits the pairing request instruction at intervals through the wireless charging receiving unit 11.
In this embodiment, the first main control unit 12 sends the pairing request instruction at intervals through the wireless charging receiving unit 11, which may be sending the pairing request instruction at preset time intervals. For example, the time interval between two adjacent pairing requests is 1s. Of course, the above-described time interval is not limited, and may be, for example, 500 ms. In this embodiment, the first main control unit 12 waits for the wireless charging receiving unit 11 to receive the pairing information returned from the pen stand in the transmission interval of the pairing request instruction. When the pairing information is not received within the transmission interval, the first main control unit 12 transmits the pairing request instruction again. For example, the first main control unit 12 transmits the pairing request command at every second transmission, and the first main control unit 12 waits for reception of the pairing information in the next second transmission interval after transmitting the pairing request command. The first main control unit 12 of this embodiment may reduce the running energy consumption of the smart pen by sending pairing request instructions at intervals.
In an alternative embodiment of the present application, the first main control unit 12 stops sending pairing requests when the stop condition is satisfied.
For example, upon receiving the pairing information, the first main control unit 12 stops transmitting the pairing request instruction. Upon receiving the pairing request, the smart pen may effect pairing. Accordingly, upon receiving the pairing information, the first main control unit 12 may stop transmitting the pairing request instruction.
Alternatively, the above-described stop condition may be that the number of times the first main control unit 12 transmits the pairing request instruction reaches a threshold value. For example, when the number of times the first main control unit 12 transmits the pairing request instruction reaches the threshold value, and the pairing information is not received, the first main control unit 12 stops transmitting the pairing request instruction. In this embodiment, in the case where the pairing information is not received, the first main control unit 12 may also stop transmitting the pairing request instruction when the number of times of transmitting the pairing request instruction reaches the threshold value. The problem of infinitely transmitting pairing request instructions due to failure to receive pairing information for some reason is avoided. The threshold value can be set according to different situations. For example, the threshold may be 3 times, 5 times, 8 times, etc.
In connection with the above embodiment, when any one of the following stop conditions is satisfied, the first main control unit 12 stops sending the pairing request instruction. One is when pairing information is received. And secondly, when the number of times of sending the pairing request command reaches a threshold value.

the first main control unit 12 sends a second charging start instruction through the wireless charging receiving unit 11, and the second charging start instruction is used for starting charging of the stylus holder.
In this embodiment, when the first main control unit 12 receives the pairing information, the first main control unit 12 transmits a first charging start instruction. The first wireless charging control unit 13 receives the first charging start instruction and starts the smart pen charging. For example, the first main control unit 12 may transmit a high-level control signal to the first wireless charging control unit 13. The first wireless charging control unit 13 starts the charging operation of the smart pen end. The first main control unit 12 may also transmit a second charge start instruction through the wireless charge receiving unit 11. The second charging start instruction is used for starting charging of the stylus holder. When the pen holder receives the second charging starting instruction, the charging function of one end of the pen holder can be started. Based on the above, the intelligent pen receives the power from the pen holder to charge. The embodiment can start charging after the intelligent pen is paired, so that automatic pairing and automatic charging are realized, and the performance of the pen is improved.
In an alternative embodiment of the present application, when the number of times of sending the pairing request instruction reaches a threshold value, and pairing information is not received,

In this embodiment, when the number of times that the first main control unit 12 further sends the pairing request instruction reaches a threshold (for example, 3 times, 5 times, etc.), and no pairing information returned by the pen holder is received, the first main control unit 12 may further send a first charging start instruction for instructing to start charging of the smart pen, and one end of the smart pen starts the charging function. For example, the first main control unit 12 may send a high-level control signal to the first wireless charging control unit 13, and the first wireless charging control unit 13 starts the charging operation of the smart pen terminal. The first main control unit 12 may also send a second charge initiation command for initiating charging of the stylus holder. When the pen holder receives the second charging starting instruction, the charging function of one end of the pen holder can be started. Based on this, the smart pen receives power from the pen holder to charge a rechargeable power source (e.g., lithium battery 14). According to the embodiment, the charging can be forcedly started under the condition that the intelligent pen can not successfully receive the pairing information for many times, so that the applicability of the intelligent pen is improved.
