As shown in fig. 1, fig. 1 is a flowchart illustrating an anti-interference method according to an exemplary embodiment, which may be used in a touch terminal, and includes the following steps 101 to 102:
in step 101, interference noise during a charging process of a touch terminal is detected.
In step 102, if the interference noise meets the preset interference condition, sequentially calling the hopping frequencies in the preset hopping frequency set to work with the optimal hopping frequency, where the optimal hopping frequency is the working frequency of the interference noise within the acceptable noise range, and the hopping frequencies in the preset hopping frequency set are sorted based on the number of times of the selected optimal hopping frequency in the historical charging process.
In the embodiment of the present disclosure, the touch terminal may be an electronic device with a touch function, such as a smart phone, a tablet computer, a PDA (Personal Digital Assistant), an e-book reader, and a multimedia player. The touch screen of the touch terminal may be a capacitive touch screen.
In the charging process of the touch terminal, whether interference noise caused by charging exists or not can be detected. Specifically, the existence and the strength of the interference noise can be judged by detecting the difference or the size of sampling data, and the sampling data is capacitance sensing data on the capacitance touch sensor acquired by the sampling circuit. The preset interference condition is a preset condition for judging whether frequency hopping operation is performed, and if the interference noise meets the preset interference condition, the abnormal touch operation condition occurs in the charging process. For example, the preset interference condition may be that the interference noise is not within an acceptable noise range. If the interference noise is within the acceptable noise range, the frequency hopping operation is not needed, and if the interference noise is not within the acceptable noise range, the frequency hopping frequencies in the preset frequency hopping frequency set are sequentially called to work at the optimal frequency hopping frequency.
In an optional implementation manner, before detecting the interference noise in the charging process of the touch terminal, it may be further determined whether the touch terminal enters a charging state, if so, the interference noise in the charging process of the touch terminal is detected, otherwise, the interference noise is not detected.
In this embodiment, after the touch terminal is connected to the charging device, the charging device charges the battery of the touch terminal through the power supply, and at this time, the touch terminal enters the charging mode. Only after the touch terminal enters the charging mode, the interference noise in the charging process of the touch terminal is detected, and resource waste caused by real-time detection is avoided.
Further, after the touch terminal is judged to enter the charging state, whether the screen is in a bright screen state or whether an operation instruction of a user to the screen is detected can be judged, if yes, interference noise in the charging process of the touch terminal is detected, and otherwise, the interference noise is not detected.
In this embodiment, since the screen is generally in the screen-off state when the user does not operate the screen, and when the screen is lighted up, it indicates that the user may operate the screen, whether the screen is in the screen-on state may be used as the trigger condition for the frequency hopping operation, or whether the user operates the screen may be directly used as the trigger condition for the frequency hopping operation. In the charging process of the touch terminal, if the screen is not lightened or an operation instruction of a user on the screen is not detected, interference detection can be avoided, and normal charging is not influenced; when the screen is lightened or an operation instruction of the user to the screen is detected, the interference detection is carried out, so that the resource waste caused by the interference detection in the whole charging process is avoided.
When the interference noise is detected to meet the preset interference condition, the frequency hopping frequencies in the preset frequency hopping frequency set can be called in sequence to work at the optimal frequency hopping frequency. The optimal hopping frequency is a hopping frequency selected from a preset hopping frequency set, and the hopping frequency is an operating frequency when the interference noise is within an acceptable noise range.
The preset frequency hopping frequency set at least comprises one frequency hopping frequency, and the frequency hopping frequencies in the preset frequency hopping frequency set are sequenced based on the number of times of the selected optimal frequency hopping frequency in the historical charging process. In the embodiment, the frequency of the selected optimal frequency hopping frequency in the historical charging process is counted, and the frequency hopping frequencies are arranged in the sequence from high to low, so that the preset frequency hopping frequency set is obtained.
As can be seen from the above embodiments, because the frequency hopping frequencies in the preset frequency hopping frequency set are ordered based on the number of times of the selected optimal frequency hopping frequency in the historical charging process, when the interference noise meets the preset interference condition, the frequency hopping frequencies in the preset frequency hopping frequency set are sequentially called, so that the optimal frequency hopping frequency can be quickly found, the touch terminal can resume normal operation as soon as possible, and convenience is brought to the user.
For the update time of the preset frequency hopping frequency set, the update operation of the preset frequency hopping frequency set may be performed before the charging or after the charging is finished. For example, the method further comprises: and counting the frequency of the optimal frequency hopping frequency selected from the preset frequency hopping frequency set according to the optimal frequency hopping frequency selected in the charging process, and reordering the frequency hopping frequencies in the preset frequency hopping frequency set based on the counting result. Therefore, after the charging is finished, the updating of the preset frequency hopping frequency set can be realized.
In an example, the touch terminal is connected with a plurality of charging devices, and the optimal frequency hopping frequency and the selected frequency in the charging process are recorded, so that the preset frequency hopping frequency set is updated according to the selected frequency hopping frequency.
In this embodiment, the preset frequency hopping set is obtained based on the optimal frequency hopping selected in the charging process of the touch terminal and the plurality of charging devices. Different charging devices share one preset frequency hopping frequency set, only one preset frequency hopping frequency set needs to be recorded in the touch terminal, and storage space is saved.
In another example, the historical charging process is a process in which the touch terminal is charged by the same charging device, and a corresponding preset frequency hopping frequency set is set for different charging devices, and before the touch terminal sequentially calls frequency hopping frequencies in the preset frequency hopping frequency set to work at an optimal frequency hopping frequency, the method further includes:
and identifying the charging equipment connected with the touch terminal.
And acquiring a preset frequency hopping frequency set corresponding to the charging equipment according to the identification result.
The correspondence between the identification information of the charging device and the preset frequency hopping frequency set may be prestored. When the identification information of the charging device connected with the touch terminal is identified and obtained, a preset frequency hopping frequency set corresponding to the obtained identification information can be searched from the corresponding relation.
In this embodiment, different charging devices are provided with corresponding preset frequency hopping frequency sets, and each preset frequency hopping frequency set is obtained based on the selected optimal frequency hopping frequency in the process that the touch terminal is charged by the same charging device. Because the optimal frequency hopping frequencies corresponding to different charging devices may be different, a corresponding preset frequency hopping frequency set is set for different charging devices, so that the selection efficiency of the optimal frequency hopping frequency can be improved, and the optimal working frequency can be quickly found for working.
In an alternative implementation, after determining the optimal frequency hopping frequency, the fingerprinting module may be informed to operate at the optimal frequency hopping frequency.
Due to the capacitive fingerprint technology, the measurement principle is consistent with that of the capacitive touch screen technology. It is also disturbed by charging equipment noise. However, when the usage scenarios of the two modules are compared, the process of touching the fingerprint identification module by the user is very short, so that the fingerprint identification module does not have enough time to perform the frequency hopping operation. After the optimal frequency hopping frequency is determined, the fingerprint identification module can be informed to work at the optimal frequency hopping frequency, and the fingerprint identification module is synchronously adjusted, so that the defects of slow response and unstable identification of the fingerprint identification module in the charging process of the touch terminal are avoided.
The fingerprint identification module is a module for fingerprint identification, and the specific identification technology can adopt the identification technology in the related technology, which is not described in detail herein.
The various technical features in the above embodiments can be arbitrarily combined, so long as there is no conflict or contradiction between the combinations of the features, but the combination is limited by the space and is not described one by one, and therefore, any combination of the various technical features in the above embodiments also belongs to the scope disclosed in the present specification.
As shown in fig. 2, fig. 2 is a flowchart illustrating another interference rejection method according to an exemplary embodiment of the present disclosure, the method includes the following steps 201 to 206:
in step 201, an interference noise during a charging process of the touch terminal is detected.
In step 202, it is determined whether the interference noise meets a preset interference condition, and if the interference noise does not meet the preset interference condition, the method returns to step 201 to continue detecting the interference noise in the charging process of the touch terminal. If the interference noise satisfies the preset interference condition, step 203 is entered.
In step 203, a charging device connected to the touch terminal is identified.
In step 204, a preset frequency hopping frequency set corresponding to the charging device is obtained according to the identification result.
The optimal frequency hopping frequency is the working frequency when the interference noise is within the acceptable noise range, and the frequency hopping frequencies in the preset frequency hopping frequency set are sorted based on the number of times of the optimal frequency hopping frequency selected in the historical charging process. The historical charging process is a process in which the touch terminal is charged by the same charging device. And setting corresponding preset frequency hopping frequency sets for different charging devices.
In step 205, the hopping frequencies in the preset hopping frequency set are sequentially called to operate at the optimal hopping frequency.
Wherein the optimal frequency hopping frequency is an operating frequency at which interference noise is within an acceptable noise range.
In step 206, after determining the optimal frequency hopping frequency, the fingerprinting module is informed to operate at the optimal frequency hopping frequency.
As can be seen from the above embodiments, because the frequency hopping frequencies in the preset frequency hopping frequency set are ordered based on the number of times of the selected optimal frequency hopping frequency in the historical charging process of the touch device and the charging device, when the interference noise meets the preset interference condition, the frequency hopping frequencies in the preset frequency hopping frequency set are sequentially called, so that the optimal frequency hopping frequency can be quickly found, and the touch terminal can resume normal operation as soon as possible. Meanwhile, after the optimal frequency hopping frequency is determined, the fingerprint identification module is informed to work at the optimal frequency hopping frequency, and the defects of slow response and unstable identification of the fingerprint identification module in charging of the touch terminal can be avoided.
