Specific implementation mode
Currently, in using the touch key-press of charge migration method control chip, it is provided with touch key-press and benchmark electricity
Hold.For each touch key-press, there are corresponding inductance capacitance Cp for corresponding metal keyboard.It is arranged when on same chip
When there are multiple touch key-press, the corresponding switching circuit of touch key-press is closed by time-multiplexed mode successively, is touched with detecting
Touch whether button is triggered.
There is one-to-one switching circuit therewith in each touch key-press, be closed in switching circuit and touched without finger
When touch key-press, is charged to reference capacitance Cx by inductance capacitance Cp, made a reservation for until the voltage on reference capacitance Cx reaches one
Value, calculates the time of entire charging process.Capacitance C on fingerfingerThe parasitism of (hereinafter referred to as Cf) between human body and the earth
Capacitance, when finger touches touch key-press, the capacitance on Cp becomes Cp+Cf.At this point, when Cp charges to reference capacitance Cx,
Since the capacitance on Cp increases, the charging time shortens.In the prior art, sentenced by the variable quantity in charging time
Whether disconnected touch key-press is triggered.
In practical applications it is found that Cp is usually smaller to the charging time data of Cx, may cannot be used directly at data
Reason.In practical applications, sampling time data (namely the obtained Cp of sampling is to charging time of Cx) are usually amplified place
Reason, sampling time data are multiplied with the amplification coefficient of setting.Therefore, it is that basis is put when judging whether to occur key-press event
Big treated sampling time data judge.
However, due to the influence of the factors such as temperature, humidity, electronic device loss, touch key-press is caused to control chip system
After running a period of time, sampling time data may change.When being triggered there are touch key-press, touch key-press
May because of amplified sampling time data beyond presetting range, lead to not normally to judge touch key-press whether by
Triggering.
In embodiments of the present invention, by setting first threshold so that first threshold is not more than theoretical maximum time data
And the difference of executeaaafunction data.Therefore, when being triggered there are touch key-press, it can effectively avoid acquisition time data beyond pre-
The case where first setting range, occurs, and then can effectively judge whether touch key-press is triggered.
It is understandable to enable above-mentioned purpose, feature and the advantageous effect of the present invention to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of invention is described in detail.
An embodiment of the present invention provides a kind of touch key-press signal processing methods, referring to Fig.1, below by way of specific steps into
Row is described in detail.
Step S101 obtains sampling time data.
In specific implementation, the corresponding reality of some touch key-press in touch key-press control chip system can be obtained
Sampling time.
In practical applications it is found that corresponding to i-th of touch key-press, when the corresponding switching circuit of i-th of touch key-press closes
When conjunction, corresponding inductance capacitance Cpi charges to reference capacitance Cx.At this point, i-th of touch key-press corresponding actual samples time
For：During inductance capacitance Cpi acquisition charge migration to reference capacitance Cx, the voltage of reference capacitance Cx is raised to pre- from 0V
If the duration of voltage.
In embodiments of the present invention, the actual samples time of acquisition can be that touch key-press i is corresponding when secondary poll
Sampling time.In practical applications, can with predetermined period to touch key-press control chip system in all touch key-press into
Row poll, within each period, all touch key-press are polled once.
In embodiments of the present invention, the actual samples time got is usually smaller, consequently, to facilitate calculating, usually may be used
It is multiplied with preset amplification coefficient with the actual samples time that will be got, using obtained product as sampling time data.
Step S102 is filtered the sampling time data, obtains filtering time data.
In practical applications, in existing touch key-press control chip system, sampling time data can be filtered
Processing, obtains filtering time data.Later, according to the difference of filtering time data and baseline time data, with preset difference value into
Row compares, and whether detection touch key-press is triggered.To the main purpose that sampling time data are filtered, when being to sampling
Between the dither signal of moment occurs in data interference signal and touch key-press when being triggered be filtered.
In specific implementation, when being filtered to sampling time data, median filter method may be used to adopting
Sample time data is filtered, and can also be filtered to sampling time data using average value filtering method.
It is understood that in practical applications, other filter processing methods can also be used to sampling time data
It is filtered, as long as when moment in sampling time data can occur interference signal and touch key-press are triggered
Dither signal is filtered.For example, using infinite-duration impulse response (Infinite Impulse Response, IIR)
Filter processing method etc..The filter processing method provided in above-described embodiment of the embodiment of the present invention is only limitted to filter processing method
It illustrates, protection scope of the present invention is not construed as limiting.
With reference to Fig. 2-, give in the embodiment of the present invention a kind of being filtered effect to multiple repairing weld time data
Schematic diagram.
As can be known from Fig. 2, there are larger interference, corresponding signals for the sampling time data 21 got in step S101
Amplitude changes greatly.After being filtered to sampling time data 21, filtering time data 22 are obtained.By sampling time data 21
Be compared with filtering time data 22, it is known that filtering time data 22 are more smooth, corresponding signal amplitude variation compared with
It is small.
Step S103, detects whether the touch key-press is triggered.
In specific implementation, it when whether detection touch key-press is triggered, is realized by decision logic, you can with
The corresponding baseline time data of touch key-press filtering time data corresponding with the touch key-press are subtracted each other, by obtained difference with
Preset difference value is compared.When the difference of baseline time data and filtering time data be more than preset difference value, then can determine that the touch
Button is triggered once；Conversely, when the difference of baseline time data and filtering time data is not more than preset difference value, judge that this is touched
Button is touched not to be triggered.
For example, touch key-press i corresponds to filtering time data Ti, and the corresponding baseline time data of touch key-press i are T0, △
T is preset difference value.(T0-Ti) is compared with △ T, if T0-Ti ＞ △ T, judge that touch key-press i is triggered once；If
T0-Ti≤△ T then judge that touch key-press i is not triggered.
It should be noted that in practical applications, controlling chip system for the same touch key-press, corresponding to each
One-to-one baseline time data can be arranged in touch key-press, an identical base can also be arranged to all touch key-press
Line time data.The setting of baseline time data can be set according to actual application demand, for example, can first pass through in advance
Self-checking obtains baseline time data.The embodiment of the present invention does not carry out the acquisition process of specific baseline time data specific
Description.
In embodiments of the present invention, when detecting that touch key-press is triggered, the touch key-press can be obtained and continuously touched
The number of hair.When the touch key-press is M times by the number of continuous trigger, then it can be determined that the touch key-press has triggering thing
Part；It, then can be in conjunction with the touch key-press is several times next time or later when the touch key-press is less than M by the number of continuous trigger
No the case where being triggered, to judge that the touch key-press whether there is trigger event.
It is not to judge that the touch key-press has triggering thing immediately that is, when detecting that touch key-press is triggered
Part, but judge the touch key-press whether by continuous trigger.Only when the touch key-press is by continuous trigger, the touch is just judged
There are trigger events for button.
In other words, it is that there are areas to judge whether touch key-press is triggered and judges touch key-press with the presence or absence of trigger event
It is other, in a cycle being polled to all touch key-press, it can be determined that whether some touch key-press is triggered；And
It judges whether trigger event, then needs in the M period being polled to all touch key-press, judge the touch key-press
Whether it is triggered.If in the M period being polled to all touch key-press, when which is triggered, then may be used
To judge the touch key-press, there are trigger events.
In practical applications, may occur the case where trigger event erroneous judgement in the presence of caused by the factors such as interference.
And in embodiments of the present invention, according to touch key-press by the number of continuous trigger to determine whether there are trigger event, so as to
To avoid the erroneous judgement of the trigger event caused by interference.
In other words, for touch key-press, there are trigger events and the concept that be two different that is triggered.Work as judgement
There are when trigger event, touch key-press is by continuous trigger M times；When judgement is triggered, touch key-press may only be triggered 1
It is secondary, it is also possible to multiple by continuous trigger.Only by continuous trigger M times, just judge that there are trigger events for touch key-press.
In specific implementation, M can be set according to actual application scenarios.For example, setting M=3.
In embodiments of the present invention, when detecting that touch key-press is not triggered, step S104 can be executed.
Step S104 reduces the amplification coefficient when the filtering time data are more than preset first threshold.
In specific implementation, when detecting that filtering time data are more than preset first threshold, then it can reduce amplification
Coefficient.Reduction adjustment is carried out to amplification coefficient, can be when detecting that touch key-press is not triggered next time, execution once subtracts
The operation of small amplification coefficient, until obtained filtering time data are not more than first threshold.
From in the above embodiment of the present invention it is found that the sampling time data obtained in step S101 can be touch key-press i
Corresponding sampling time data when secondary poll.After getting when time poll corresponding sampling time data, Ke Yigen
According to the corresponding sampling time data of preceding n times poll before secondary to carrying out filter processing when secondary sampling time data, worked as
The corresponding filtering time data of sampling time data of secondary poll.In practical applications, N is positive integer.For example, N=4.
In embodiments of the present invention, when being adjusted to amplification coefficient, it can detect that touch key-press does not have next time
When being triggered, reduce amplification coefficient.And so on, until when n-th detects that touch key-press is not triggered, according to subtracting
When the filtering time data that amplification coefficient after small obtains are not more than first threshold, stopping is adjusted amplification coefficient.
For example, N=1, then when time after next time, stopping is adjusted amplification coefficient.
In embodiments of the present invention, first threshold can meet following condition：X≤Y-Z；Wherein, X is first threshold, and Y is
Presupposition theory maximum time data, Z are the executeaaafunction data judged when touch key-press is triggered.Presupposition theory maximum time number
Can be according to Y：It is capable of detecting when corresponding maximum time data when touch key-press is triggered.When judgement touch key-press is triggered
Executeaaafunction data can first pass through multiple measurement data and calculate to obtain in advance.For example, can be touched according to 100 touch key-press
Corresponding sampling time data when hair, averaged empirically time data.
With reference to Fig. 3, a kind of waveform signal of existing filtering time data when not being adjusted to amplification coefficient is given
Figure.
In Fig. 3, at T1 moment~T2 moment, filtering time data continue to increase with the variation of time.The T2 moment~
T3 moment, filtering time data remain unchanged.At T3 moment~T4 moment, touch key-press is triggered.At this point, can be with from Fig. 3
Find out, at T3 moment~T4 moment, touch key-press is triggered, and filtering time data when touch key-press is triggered have exceeded software
Program presets range, at this point, software program can not normally judge whether touch key-press is triggered.
In embodiments of the present invention, with reference to Fig. 4, give in the embodiment of the present invention a kind of being adjusted amplification coefficient
The waveform diagram of filtering time data afterwards.
In Fig. 4, at T1 moment~T2 moment, filtering time data continue to increase with the variation of time.The T2 moment~
The T3 moment detects therefore filtering time data gradually reduce amplification coefficient more than first threshold so that after reduction
The filtering time data that amplification coefficient obtains are not more than first threshold.At T3 moment~T4 moment, filtering time data are kept not
Become.At T4 moment~T5 moment, touch key-press is triggered.At this point, as can be known from Fig. 4, when touch key-press is triggered, filtering time
Data are not departing from the range that presets of software program, and therefore, whether software program normally can judge touch key-press
It is triggered.
It can be seen that in embodiments of the present invention, when not detecting that touch key-press is triggered, and filtering time data are big
When preset first threshold, reduce amplification coefficient so that the filtering time data obtained according to the amplification coefficient after reduction are not
More than first threshold.By setting first threshold so that first threshold is no more than theoretical maximum time data and executeaaafunction number
According to its difference.Therefore, when being triggered there are touch key-press, it can effectively avoid acquisition time data from exceeding and preset range
Situation occurs, and then can effectively judge whether touch key-press is triggered.
In specific implementation, when detecting that touch key-press is not triggered, and filtering time data are less than preset second
