Fig. 1 is the schematic flow sheet of a kind of method of adjusting terminal touch screen anti-interference filtration module firmware parameter value that the embodiment of the present invention one provides, the method can be carried out by the device of adjusting terminal touch screen anti-interference filtration module firmware parameter value, described device can be realized by software and/or hardware, a part that can be used as terminal is built in terminal inner, also can be the stand-alone product that can carry out with terminal data communication.Referring to Fig. 1, the method specifically comprises the steps:
Step 110, in the situation that listening to terminal and adapter and connecting to charge, detect the charging current parameter value in setting-up time section.
In the present embodiment, can create watcher thread, monitor a terminal every the fixed cycle and whether set up and be connected to charge with adapter.In the situation that listening to terminal and adapter and connecting to charge, detect the charging current parameter value in setting-up time section.Wherein, charging current parameter value include but not limited to be: the range value of the charging current on each timing node in setting-up time section, each timing node at the crest value place of the crest value of the charging current in setting-up time section and/or charging current etc.In embodiments of the present invention, described crest value refers to the crest value of charging current amplitude.
Detect the charging current parameter value in setting-up time section, can be specially: obtain the charging current parameter value in the setting-up time section that the charging module of terminal reports.In embodiments of the present invention, the charging module of terminal is connected with adapter, the parameter value of adapter charging current in to the process of terminal charge can be detected.
Step 120, according to detected charging current parameter value, determine corresponding to the charging interference metric values in described setting-up time section.
After the charging current parameter value obtaining in setting-up time section, can determine that one corresponding to the charging interference metric values in described setting-up time section according to described charging current parameter value.
In the present embodiment, can first resolve obtained charging current parameter value, thereby obtain the variation characteristic of detected charging current parameter value, then according to obtained variation characteristic, determine corresponding to the charging interference metric values in described setting-up time section.
Wherein, according to obtained variation characteristic, determine corresponding to the charging interference metric values in described setting-up time section, can comprise: the distance between the variation characteristic that calculating obtains and default standards change feature, then obtain the charging interference metric values in described setting-up time section according to the distance of calculating, distance is larger, and charging interference metric values is less.
For example, in the time that the charging current parameter value in setting-up time section is the range value of the charging current on each timing node, the variation characteristic obtaining is: the period of change of the range value of charging current in setting-up time, default standards change is characterized as: in the standards change cycle of the range value of charging current, the distance between the two can utilize Euclidean distance computing formula to calculate.Certainly, those of ordinary skill in the art should be understood that and can also determine corresponding to the charging interference metric values in described setting-up time section according to detected charging current parameter value according to other modes.For example, calculate one corresponding to the charging interference metric values in described setting-up time section according to setting formula, the variable in this formula is detected charging current parameter value.For example, the range value that is the charging current on each timing node in setting-up time section at detected charging current parameter value, this formula can be set as to the mean value when the charging current range value on each timing node in setting-up time section is greater than while setting amplitude threshold, with described mean value be directly proportional change function, its functional value is the charging interference metric values in setting-up time section.

The firmware parameters value that will obtain after adjustment can be determined according to pre-stored good regulation rule.Concrete, the firmware parameters value after the determined adjustment of this rule can not be associated with original firmware parameters value that adapter connects to carry out under charge condition with determined charging interference metric values and terminal.Larger in charging interference metric values, adapter, in the larger situation of the charging annoyance level of terminal touch screen, should be adjusted the firmware parameters value of anti-interference filtration module, and anti-interference filtration module can be disturbed the charging of terminal touch screen by offset adapter.
For example, in the present embodiment, the scope of defined charging interference metric values is 0-1, in the time that determined charging interference metric values is less than 0.3, adapter is less to the charging annoyance level of terminal touch screen, now can not adjust the filter value of terminal touch screen anti-interference filtration module; When determined charging interference metric values is greater than 0.3 and while being less than 0.7, adapter is larger to the charging annoyance level of terminal touch screen, now the filter value of anti-interference filtration module can be adjusted into terminal and not connect to carry out 1.5 times of filter value under charge condition with adapter; When determined charging interference metric values is greater than 0.7 and while being less than or equal to 1, adapter is very large to the charging annoyance level of terminal touch screen, now the filter value of anti-interference filtration module can be adjusted into terminal and not connect to carry out 1.8 times of filter value under charge condition with adapter.
The technical scheme that the embodiment of the present invention provides, it is not the artificial firmware parameters value of setting based on experience value, but in the situation that listening to terminal and adapter and connecting to charge, obtain by detecting charging current parameter value the interference metric values of charging, and then according to charging interference metric values, the firmware parameters value of terminal touch screen anti-interference filtration module is adjusted, thereby the setting that makes firmware parameters value possesses good adaptivity, and compared with artificial setting firmware parameters value, can be good at reducing the impact that adapter detects the touch of terminal touch screen in charging process.
