The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In some embodiments of the present invention, a charging interference processing method is provided, and with reference to fig. 1, the method includes:
step 101, detecting that a mobile terminal is in a charging state, and determining whether the mobile terminal is in a fast moving state.
When the mobile terminal is detected to be in the charging state, whether the mobile terminal is in the fast moving state is determined firstly to distinguish charging on vehicles such as a high-speed rail and charging in a conventional commercial power scene, so that special frequency hopping processing is carried out on charging interference on the vehicles such as the high-speed rail, and the problem of large noise interference is solved.
And 102, when the mobile terminal is in a fast moving state, performing first frequency hopping processing according to common-mode noise transmitted by a charging data line. Under the common mode noise of the same frequency, a first amplitude range of the common mode noise triggering frequency hopping in the first frequency hopping processing is larger than a second amplitude range of the common mode noise triggering frequency hopping in the second frequency hopping processing.
Here, when the mobile terminal is in a charging state and in a fast moving state, it may be determined that the mobile terminal is charged on a vehicle such as a high-speed rail, and since a power source is unstable on the vehicle such as the high-speed rail, noise is large, if a conventional frequency hopping process is adopted, a problem of a disordered frequency hopping will occur, which causes a problem of a disordered and insensitive touch screen. In this step, when the mobile terminal is in a charging state and in a fast moving state, a first frequency hopping process is performed according to the common mode noise transmitted by the charging data line, wherein under the common mode noise of the same frequency, a first amplitude range of the common mode noise triggering frequency hopping in the first frequency hopping process is larger than a second amplitude range of the common mode noise triggering frequency hopping in the second frequency hopping process, that is, when the mobile terminal is charged on a vehicle such as a high-speed rail, the mobile terminal can only hop frequency when the common mode noise exceeds the first amplitude range triggering frequency hopping, and compared with the frequency hopping process of a conventional commercial power scene, the amplitude range of the common mode noise triggering frequency hopping is increased, the noise amplitude which can be tolerated is increased, the occurrence of the random frequency hopping is avoided, and the problems of a touch screen, such as a random hop point, insensitivity and the like are.
And 103, when the mobile terminal is not in a fast moving state, performing second frequency hopping processing according to the common-mode noise transmitted by the charging data line.
Here, when the mobile terminal is in a charging state and is not in a fast moving state, it can be determined that the current charging scene is a conventional commercial power scene, and then second frequency hopping processing is performed according to common-mode noise transmitted by the charging data line, so that the problem of touch screen jumping caused by the common-mode noise during charging of the conventional commercial power scene can be avoided.
According to the charging interference processing method provided by the embodiment of the invention, when the mobile terminal is in a charging state and in a fast moving state, namely when the mobile terminal is charged on vehicles such as a high-speed rail, frequency hopping can be carried out only when the common-mode noise exceeds a first amplitude range for triggering frequency hopping, and the first amplitude range is larger than a second amplitude range for triggering frequency hopping when a conventional commercial power scene is charged, so that the amplitude range of the common-mode noise for triggering frequency hopping is enlarged, the tolerable noise amplitude is improved, the occurrence of random frequency hopping is avoided, the problems of random hop points, insensitive touch screen and the like are avoided, and the user experience is improved.
Further, the number of the operating frequency bands of the touch ICs in the first frequency hopping processing is greater than the number of the operating frequency bands of the touch ICs in the second frequency hopping processing.
Here, the touch IC in the first frequency hopping process is pre-divided into a first preset number of operating frequency bands, and the touch IC in the second frequency hopping process is pre-divided into a second preset number of operating frequency bands, where the first preset number is greater than the second preset number.
At this time, when the mobile terminal is in a charging state and is in a fast moving state, the first frequency hopping processing is performed according to the common mode noise transmitted by the charging data line, the number of the working frequency bands of the touch IC in the first frequency hopping processing is larger than that of the touch IC in the second frequency hopping processing, that is, when the mobile terminal is charged on a vehicle such as a high-speed rail, the number of the selectable frequency bands of the touch IC is larger, which is more beneficial to the processing of the noise.
Optionally, the step 102 includes:
step 1021, detecting the frequency and amplitude of the common mode noise when the mobile terminal is in a fast moving state.
Here, when the mobile terminal is in a charging state and in a fast moving state, that is, when charging on a vehicle such as a high-speed rail, the frequency and amplitude of the common mode noise are detected in order to determine whether to perform frequency hopping of the touch IC.
Step 1022, in a first preset number of working frequency bands divided in advance, a first working frequency band corresponding to the frequency of the common mode noise and an amplitude corresponding to the first working frequency band are determined.
Here, the touch IC is pre-divided into a first preset number of operating frequency bands, and the first preset number is greater than the second preset number. In this step, in a first preset number of working frequency bands, a first working frequency band corresponding to the common mode noise and an amplitude corresponding to the first working frequency band are determined, so as to determine whether to perform frequency hopping of the touch IC and a working frequency band selected when performing frequency hopping of the touch IC.
And 1023, when the amplitude of the common mode noise is detected to be larger than the amplitude corresponding to the first working frequency band, outputting an instruction that the touch IC jumps to other working frequency bands except the first working frequency band for working.
When the amplitude of the common mode noise is detected to be larger than the amplitude corresponding to the first working frequency band, an instruction that the touch IC jumps to other clean working frequency bands except the first working frequency band for working is output, and noise interference is avoided. And the first preset number is larger than the second preset number, so that the touch IC has more selectable frequency bands, and is more favorable for processing noise. Based on the above, at this time, under the common mode noise of the same frequency, the first amplitude range of the common mode noise triggering frequency hopping in the first frequency hopping processing is larger than the second amplitude range of the common mode noise triggering frequency hopping in the second frequency hopping processing, that is, the amplitude corresponding to the first working frequency band is larger than the amplitude corresponding to the second working frequency band corresponding to the frequency of the common mode noise in the second frequency hopping processing, so that the amplitude range of the common mode noise triggering frequency hopping is enlarged, the tolerable noise amplitude is improved, the occurrence of random frequency hopping is avoided, and the problems of random hop points and insensitivity of the touch screen are avoided.
The step 103 includes:
and step 1031, when the mobile terminal is not in a fast moving state, detecting the frequency and amplitude of the common mode noise.
Here, when the mobile terminal is in a charging state and is not in a fast moving state, that is, when the mobile terminal is charged in a normal commercial power scene, the frequency and amplitude of the common mode noise are detected, so as to determine whether to perform frequency hopping of the touch IC.
Step 1032, in a second preset number of working frequency bands divided in advance, determining a second working frequency band corresponding to the frequency of the common mode noise and an amplitude corresponding to the second working frequency band.
Here, the touch IC is pre-divided into a second preset number of operating frequency bands, and the first preset number is greater than the second preset number. In this step, in a second preset number of working frequency bands, a second working frequency band corresponding to the common mode noise and an amplitude corresponding to the second working frequency band are determined, so as to determine whether to perform frequency hopping of the touch IC and a working frequency band selected when performing frequency hopping of the touch IC.
Step 1033, when it is detected that the amplitude of the common mode noise is greater than the amplitude corresponding to the second operating frequency band, outputting an instruction that the touch IC jumps to other operating frequency bands except the second operating frequency band; wherein the first preset number is greater than the second preset number.
When the amplitude of the common mode noise is detected to be larger than the amplitude corresponding to the second working frequency band, an instruction that the touch IC jumps to other clean working frequency bands except the second working frequency band for working is output, and noise interference is avoided.
