Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1A is a flow diagram illustrating a noise detection method according to an exemplary embodiment, and FIG. 1B is a scene diagram illustrating a noise detection method according to an exemplary embodiment; the noise detection method can be applied to a terminal, and the terminal in the disclosure can be any intelligent terminal with an internet access function, for example, a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), and the like can be embodied.
The terminal can access the router through the wireless local area network and access the server on the public network through the router. As shown in fig. 1A, the noise detection method includes the following steps 101-102:
in step 101, when the key signal transmitter does not transmit a signal, the key signal received by the key signal receiver is detected.
In an embodiment, for the mutual capacitance type key, in the scanning stage of normal operation, the key signal transmitter Tx sensor transmits a signal at a certain frequency, and correspondingly, the key signal receiver Rx sensor receives the signal, so as to trigger the key to implement a corresponding function.
In the embodiment of the present disclosure, a detection phase is added for the key signal transmitter, and the scanning phase and the detection phase are alternately performed in a set time period, for example, the scanning phase lasts for a first time period, then the detection phase lasts for a second time period, and then the scanning phase is performed again.
In one embodiment, theoretically, when the key signal transmitter does not transmit a signal, the key signal receiver should not detect a signal, and thus if a signal is detected at the key signal receiver, it can be determined that the interference noise signal is currently present.
In step 102, it is determined that interference noise exists based on a relationship between the key signal and a preset key signal threshold.
In one embodiment, a key signal threshold is set for the detection phase, and then the presence of interference noise is determined based on the relationship between the key signal received by the key signal receiver and the key signal threshold.
For example, a key signal greater than or equal to a key signal threshold may determine that a first noise signal is present, and if the key signal is less than the key signal threshold, a second noise signal may be determined to be present. It is apparent that the first noise signal is larger than the second noise signal. For the second noise signal, it is negligible in the embodiment of the present disclosure because it is small. For the first noise signal, since it is large, it may cause false triggering of the key, so the key signal threshold may be adjusted when the first noise signal is detected.
In an exemplary scenario, as shown in fig. 1B and fig. 1C, a smartphone with mutually-compatible keys is taken as an example for illustration, and in the scenario shown in fig. 1B and fig. 1C, the smartphone is included as a terminal.
The key of the smart phone is a mutual-capacitance key, that is, the key comprises a Tx transmitter and an Rx receiver, wherein the Tx transmitter enters a detection stage of a set time period after a scanning stage of the set time period, the Tx transmitter transmits a signal at a certain frequency in the scanning stage, and the Rx receiver detects a received signal; in the detection phase, the Tx transmitter does not transmit a signal, and the Rx receiver continues to detect the received key signal. And comparing the received key signal with a preset key signal threshold, and determining that interference noise exists when the key signal is greater than or equal to the key signal threshold.
Please refer to the following embodiments for details of how to detect noise.
Therefore, according to the method provided by the embodiment of the disclosure, when the key signal emitter does not emit a signal, the key signal received by the key signal receiver is detected, and the key signal is compared with the preset key signal threshold value, so as to determine whether an interference noise signal exists, and determine whether the key is in a strong interference environment, so that anti-interference adjustment can be timely made for interference, the problem that the key is easily triggered by mistake due to interference noise in the related art is solved, and the probability of key false triggering is reduced.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
FIG. 2 is a flow diagram illustrating another method of noise detection in accordance with an exemplary embodiment; in this embodiment, an example of how to adjust the key signal threshold is described by using the above method provided in the embodiment of the present disclosure, as shown in fig. 2, the method includes the following steps:
in step 201, the preset percentage is read.
In one embodiment, the terminal has a percentage, e.g. 30%, 50%, pre-stored therein for calculating the second signal threshold.
In step 202, a second signal threshold is calculated based on the percentage and the first signal threshold.
In an embodiment, the second signal threshold is higher than the first signal threshold, and the second signal threshold may be calculated by increasing a corresponding percentage based on the first signal threshold.
In step 203, the key signal threshold is set from the current first signal threshold to the calculated second signal threshold.
In an embodiment, the key signal threshold is set to the second signal threshold calculated in the previous step.
In the embodiment of the present disclosure, through the above step 201 and 203, the second signal threshold may be calculated based on a preset percentage, which is simple and easy to operate, wherein the percentage may be set based on an empirical value.

in step 301, the application currently using the antenna is determined.
In one embodiment, different APPs use antennas, and the interference caused by the different APPs is different. For example, the interference signal generated by the antenna used in the call process is different from the interference signal generated by the navigation APP using the antenna.
In an embodiment, the terminal obtains the magnitude of interference signals caused in different APP using processes based on experience in advance, and sets corresponding key signal thresholds respectively based on different interference signals, and stores the corresponding key signal thresholds correspondingly.
In step 302, the corresponding relationship between the application program and the signal threshold is read, and the signal threshold corresponding to the current application program is determined as the second signal threshold.
In an embodiment, the terminal reads a pre-stored correspondence between an APP and a signal threshold to determine a second signal threshold corresponding to the current APP.
In step 303, the key signal threshold is set from the current first signal threshold to the second signal threshold.
In the embodiment of the present disclosure, through the above step 301 and step 303, the second signal threshold corresponding to the current APP may be determined based on the corresponding relationship between the preset APP and the signal threshold, and this way can obtain a more accurate second signal threshold, so as to effectively avoid the interference signal for different APPs.

in step 401, the type of the current terminal is determined.
In one embodiment, the terminals are different, and the antennas thereof are different, for example, the positions of the antennas may be different, and the interference suffered by the keys at different positions is different; for another example, the thickness of the cover glass also affects the setting of the signal threshold, when the cover glass is thin, the signal is strong, and the signal threshold can be set to be high; when the cover glass is thick, the signal is weak, and the signal threshold can be set lower.
In one embodiment, based on experience, various types of terminal correspondence with signal thresholds may be stored in the terminal.
In step 402, the corresponding relationship between the type of the terminal and the signal threshold is read, and the signal threshold corresponding to the type of the current terminal is determined as the second signal threshold.
In an embodiment, the terminal determines the second signal threshold by reading a pre-stored correspondence between the terminal type and the signal threshold.
In step 403, the key signal threshold is set from the current first signal threshold to the second signal threshold.
In the embodiment of the present disclosure, through the steps 401 and 403, the second signal threshold corresponding to the current terminal type may be determined based on the preset corresponding relationship between the terminal type and the signal threshold, and the second signal threshold obtained in this way better conforms to the respective characteristics of the terminals, so as to effectively avoid the interference signal for different types of terminals.
In the above embodiment, when the terminal detects that the antenna function is turned off, the current signal threshold may be set from the second signal threshold to the first signal threshold, where the first signal threshold is the default signal threshold.
