Fig. 2 illustrates a control method for preventing near field transmission misidentification provided in an embodiment of the present application, which is applied to a control system and an electronic device for preventing near field transmission misidentification provided in an embodiment of the present application, and is implemented by software and/or hardware of the control system and the electronic device. An embodiment of the method will now be described by way of example with reference to the powered toothbrush 100 shown in figure 1 above. It should be understood that the following examples are only for illustrating the working process of the method, and are not specific limitations on the application objects of the method.
As shown in fig. 2, the method includes steps S01 to S04. The specific realization principle of each step is as follows:
s01: and the near field transmission card searching source sends out a first card searching signal at the beginning of the first card searching period.
The first card-seeking period is a predetermined time interval, which is 0.125 seconds in some embodiments, and may be a value between 40 and 50 milliseconds in some embodiments.
In one embodiment of the present application, a card-seeking module 111 in handle 110 of electric toothbrush 100 sends a card-seeking signal at the beginning of the first card-seeking cycle. Specifically, the card seeking chip 1111 in the card seeking module 111 sends a card seeking signal to the surrounding space of the card seeking module 111 through the card seeking coil 1112 at the beginning of the first card seeking period.
S02: if the first feedback signal is not received within the card searching time, changing the initial state of the card searching failure mark into a first state; determining the card searching period as the first card searching period; the first feedback signal is a signal sent back by the near field transmission tag in response to the card seeking signal.
For the control system, the card searching time length is the time length from sending a card searching signal to the near field transmission tag from the near field transmission card searching source to receiving a feedback signal sent by the near field transmission tag. Specifically, in the electric toothbrush 100 shown in fig. 1, the card searching time is a time between when the card searching module 111 sends a card searching signal and when the card searching module receives a feedback signal generated and sent by the NFC tag in response to the card searching signal. It should be understood that the card-searching time period can be obtained through testing, and the time period can also be an average value of a plurality of testing results, and can also be a product of a testing value and an adjusting coefficient. Typically, the adjustment factor is greater than 1. The card seek duration is typically a value between 40 and 50 milliseconds. The card searching time length can be less than or equal to the first card searching period, and preferably the two are equal.
In some embodiments, the card seeking duration is equal to the first card seeking period.
In other embodiments, the card search duration is less than the first card search period.
The card-seeking failure flag may be a variable in a program executed by the controller 112, or may be a state of a designated storage location in a memory readable and writable by the controller 112, or a combination of states of a plurality of designated storage locations, which is not specifically limited in this application. In a specific example, the card-searching failure flag may be a flag bit, where 0 is an initial state of the flag bit, and if the card-searching fails once, the flag bit is incremented by 1 to become the first state. If the card searching is successful for the second time, the flag bit is cleared, and the initial state is returned. In some implementations, if there is a third card search, if the card search fails again, the flag bit is incremented by 1, i.e., the flag bit is 2, which may also be regarded as the second state of the flag bit. If there are more card searches, analogize in the above way.
In some embodiments, the state of the card-seeking failure flag is changed to be incremented from 0, or may be decremented from a certain value, such as 10 in the initial state, 9 in the first state, and 8 in the second state.
In some embodiments, a feedback signal flag is set in the near field transmission source to identify whether a feedback signal is received. In particular, the feedback signal flag can be controlled by the card searching module 111 or the controller 112, and the present application is not limited thereto. The flag bit of the feedback signal has two states of 0 and 1, and the initial state is 0. And after the near field transmission source receives the feedback signal, changing the state of the flag bit of the feedback signal into 1. And after sending a card searching signal, detecting the flag bit of the feedback signal in the card searching time, if the flag bit of the feedback signal is 0, indicating that the feedback signal is not received, otherwise, indicating that the feedback signal is received.
In an embodiment of the present application, if the card seeking module 111 does not receive a feedback signal sent by the NFC tag in response to the card seeking signal within the card seeking duration after the card seeking module 111 sends the card seeking signal, the controller 112 changes the card seeking failure flag from the initial state to the first state, and in a specific embodiment, changes the flag bit from 0 to 1. Meanwhile, the card seeking period is determined as the first card seeking period, that is, the card seeking module 111 sends a card seeking signal to the surrounding space periodically in the first card seeking period.
S03: and the near field transmission card searching source sends a second card searching signal after the first card searching period.
In an embodiment of the present application, the timing is started after the card searching module 111 sends out the first card searching signal, and when the duration of the first card searching period is reached, the card searching module 111 sends out the second card searching signal to the surrounding space.
In some embodiments, the card seeking module 111 periodically sends the second card seeking signal to the surrounding space in the first card seeking period. It should be understood that the first card-searching signal and the second card-searching signal may be card-searching signals of the same frequency or different frequencies, or may be card-searching signals carrying the same data content or carrying different data contents. The first card-seeking signal and the second card-seeking signal are used herein only for distinguishing the purpose or timing of sending the card-seeking signal, and are not limited to the card-seeking signal itself.
S04: if a second feedback signal is received within the card searching time length, changing the card searching failure mark into an initial state; the second feedback signal is a signal sent back by the near field transmission tag in response to the second card seeking signal; and changing the card searching period into a second card searching period.
The second card searching period is a preset time interval. In some embodiments, the first card-seeking period is much smaller than the second card-seeking period. In other embodiments, the second card-seeking period is at least 8 times the first card-seeking period.
The first feedback signal and the second feedback signal are used herein only for distinguishing the purpose or timing of the feedback signal, and are not limited to the frequency of the feedback signal itself or the data content carried by the feedback signal.
In an embodiment of the application, if the card seeking module 111 receives the second feedback signal within a second preset time period after the card seeking module 111 sends the card seeking signal again, that is, after the second card seeking signal is sent, the card seeking module 111 determines that the card seeking result is that an NFC tag is nearby, and the controller 112 sets the card seeking failure flag to the initial state. In a specific embodiment, the card-searching failure flag may be a flag bit, and 0 is the initial state of the flag bit. In some embodiments, the initial state of the flag bit is determined when the second feedback signal is received within the card-seeking duration, regardless of the current state of the flag bit. In a specific embodiment, the initial state is a connected flag, and setting the card-searching failure flag to the initial state may be writing the connected flag of the NFC card in a specified storage location. In another embodiment, the write failure flag of the card-seeking failure flag is cleared.
It should be understood that, in the embodiment of the present application, a near field transmission card seeking source and a near field transmission tag are provided, where the near field transmission card seeking source sends a card seeking signal according to a certain card seeking period, the card seeking period includes a first card seeking period and a second card seeking period, and a card seeking failure flag is set in the near field transmission card seeking source; after the near field transmission card searching source sends out a first card searching signal when the first card searching period begins, if the first feedback signal is not received within the card searching time, whether the first feedback signal is not received is judged to be misjudged by sending a second card searching signal and detecting whether the second feedback signal is received.
On one hand, when the first feedback signal is not received within the card searching duration, the card searching failure flag is set to be in a first state, and the communication between the current near field transmission card searching source and the near field transmission label is marked to be in an uncertain state; and after sending a second card searching signal, under the condition of receiving a second feedback signal, changing the card searching failure mark into an initial state, and marking that the communication between the current near field transmission card searching source and the near field transmission label is in a stable communication state. Therefore, the communication states of the near field transmission card searching source and the near field transmission label are marked by adopting the card searching failure mark, and when the first feedback signal is not received, the card searching failure mark is set to be in the first state, so that the situation that the near field transmission card searching source immediately judges that the near field transmission label is separated from the communication range of the near field transmission card searching source when the near field transmission card searching source accidentally does not receive the feedback signal of the near field transmission label can be avoided, and the misjudgment of the near field transmission caused by the interference of accidental near field transmission errors can be prevented. When the method is applied to the electric toothbrush, because misjudgment of the electric toothbrush and near field transmission errors are prevented, the method plays a role in avoiding unnecessary error prompt and energy consumption loss caused by the unnecessary error prompt.
On the other hand, by setting two different card searching periods, when the card searching failure marks are in different states, the near field transmission card searching source searches the card by adopting the corresponding card searching period, so that the energy consumption of the near field transmission card searching source is adapted to the communication state of the near field transmission card searching source, and the energy consumption of the near field transmission card searching source can be flexibly adjusted according to the communication state of the near field transmission card searching source. When the method is applied to the electric toothbrush, the effects of reducing the power consumption of the electric toothbrush and prolonging the service life of the electric toothbrush can be achieved.
In some embodiments, in step S03, the card seeking module 111 sends a second card seeking signal to the surrounding space in a first card seeking cycle. That is, the card-seeking module 111 sends the second card-seeking signal to the surrounding space a plurality of times. If the second feedback signal is not received within the card searching time after the second card searching signal is sent each time, the card searching failure flag is set to the second state, and in a specific example, the card searching failure flag is increased by 1. In some implementations, the secondary card searching still fails and still cannot ensure that the reliable confirmation brush head is taken away, so a tertiary card searching mechanism can be further arranged to ensure the accuracy of the result. If the card-searching still fails for three times, the brush head is really taken away, and the card is not misread. In some embodiments, if the card-seeking duration is equal to the first card-seeking period, and the duration of the three card-seeking mechanisms is half of the second card-seeking period, the second card-seeking period needs to be at least 8 times greater than the first card-seeking period. In a specific embodiment, the second card seeking period is 1 second.
On the basis of the above embodiment of the control method for preventing the near field transmission from being recognized incorrectly in fig. 2, fig. 3 shows another implementation manner provided by the embodiment of the present application, and as shown in fig. 3, the method further includes the following steps:
s05: and if the first feedback signal is received within the card searching time length after the first card searching signal is sent out, taking the second card searching period as the card searching period.
In one embodiment of the present application, step S05 may be performed after step S01.
In an embodiment of the application, if the card seeking module 111 receives the first feedback signal within the card seeking duration after the card seeking module 111 sends the card seeking signal, the card seeking module 111 determines that the card seeking result is that an NFC tag exists nearby. At this time, the second card seeking period is taken as the card seeking period, that is, the card seeking module 111 sends a card seeking signal to the surrounding space period periodically in the second card seeking period. The same steps included in the embodiment shown in fig. 3 and the embodiment shown in fig. 2 are not described in detail here, and please refer to the corresponding description of the embodiment shown in fig. 2.
On the basis of the above embodiment of the control method for preventing the near field transmission from being recognized incorrectly in fig. 2, fig. 4 shows another implementation manner provided by the embodiment of the present application, and as shown in fig. 4, the method further includes the following steps:
s06: if the second feedback signal is not received within the card searching time after the second card searching signal is sent out, changing the card searching failure mark into an initial state; and changing the card searching period into the second card searching period.
In one embodiment of the present application, step S06 may be performed after step S03.
In an embodiment of the present application, the card searching module 111 sends the card searching signal again, that is, after sending the second card searching signal, the second feedback signal is not received within the card searching duration, and the card searching module 111 determines that there is no NFC tag nearby, that is, the brush head has been removed, and then the card searching module 111 changes the card searching failure flag to the initial state. It can be understood that after the secondary card searching failure is confirmed, if the third card searching judgment is not performed, the card searching failure flag is restored to be in the initial state, and the influence on the subsequent operation is avoided. The same steps included in the embodiment shown in fig. 4 and the embodiment shown in fig. 2 are not described in detail here, and please refer to the corresponding description of the embodiment shown in fig. 2.
In some embodiments, the electric toothbrush 100 may also prompt the user that the NFC card connection has been disconnected by turning on a prompt message. In one particular example, the electric toothbrush includes a plurality of indicator lights; the controller 112 starts a prompt message, including: the controller 112 controls a plurality of indicator lights to flash in turn, for example, to prompt in a ticker manner.
Fig. 5 is a flowchart illustrating an embodiment of the present invention for controlling the near field transmission error recognition prevention, wherein the control method is applied to the electric toothbrush 100, and the card seeking chip 1111 of the toothbrush handle sends a first card seeking signal to the surrounding space through the card seeking coil 1112 at the beginning of a first card seeking cycle.
At this time, if there is a brush head 120 nearby, the tag chip of the NFC tag 121 in the brush head receives the first card seeking signal through the tag coil, and the tag chip generates a feedback signal through a preset program and transmits the feedback signal to the surrounding space through the tag coil.
After the card seeking chip 1111 receives the first feedback signal sent by the NFC tag 121 through the card seeking coil 1112, the card seeking chip 1111 notifies the controller 112, and the controller 112 determines that the card seeking result is that there is an NFC tag 121 nearby, that is, there is a brush head 120 nearby. The controller 112 sets the card-search failure flag to the initial state.
And the card searching device takes the second card searching period as a card searching period and carries out next card searching after the second card searching period.
The time length from the time when the card searching module 111 sends the card searching signal to the time when the card searching module receives the feedback signal sent by the NFC tag can be obtained through testing, and the time length is used as the card searching time length. It should be understood that the card search time period may be equal to or less than the first card search period.
If the card searching module 111 does not receive the first feedback signal sent by the NFC tag 121 in response to the first card searching signal within the card searching duration, the controller 112 sets the card searching failure flag to be in the first state, and the card searching module sends the card searching signal again, that is, the second card searching signal.
If the card seeking module 111 does not receive the second feedback signal sent by the NFC tag 121 in response to the second card seeking signal within the card seeking duration after the card seeking module 111 sends the second card seeking signal, it is determined that the card seeking result is that there is no NFC tag nearby. In some embodiments, the controller controls a plurality of indicator lights to flash in turn, for example, to prompt in a ticker fashion.
If the card seeking module 111 receives the second feedback signal sent by the NFC tag 121 within the card seeking duration after the card seeking module 111 sends the second card seeking signal, the card seeking module 111 determines that the card seeking result is that an NFC tag is nearby, and the controller sets the card seeking failure flag to the initial state.
It should be understood that, by the control method for preventing the near field transmission misidentification provided by the embodiment of the application, on one hand, a stable NFC card searching method can be provided, so that the situation that prompt information is triggered due to accidental card reading failure to cause misunderstanding of a user is avoided; on the other hand, the power consumption of the electric toothbrush can be reduced, and the service life of the electric toothbrush is prolonged.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
