Description
Technical field
The present invention relates to a kind of touch key-press more particularly to a kind of jamproof processing methods of membrane keyboard, and use
The electric appliance of the processing method.
Background technology
Touch key-press is widely used in various operating terminals at present, such as air-conditioning, electromagnetic oven, gas water-heating furnace product
Operation display board etc. uses touch key-press to design, and the application of touch key-press is more universal, is wanted to its reliability, anti-interference
Ask higher.
And the detection of touch key-press at present is mainly that capacitive way detection is on the high side, capacitive way is detected by power-supply fluctuation shadow
Sound is larger, and a main cause of power-supply fluctuation is power consuming load variation, and if loading demand has large change suddenly, then power supply has
Significant change, at this time button detection will be interfered by one, it is possible to cause button detection abnormal, occur button can not discharge or
The case where error detection.For having used for product of the individual chip to handle touch key-press task, software and hardware may needle
More by force to button anti-interference process ability（Since the chip is only responsible for processing touch key-press task, basic resource is all filter
Wave algorithm is prepared）, but for having used master control IC to be detected touch key-press, since task run is more, may just not have
So more software and hardware resources go to reinforce anti-interference process.
Invention content
In order to solve drawbacks described above existing in the prior art, the present invention proposes a kind of jamproof processing side of membrane keyboard
Method includes the following steps：
Step 1, it monitors whether that a button is pressed while thering is load to change；If no, continuing to monitor；If so, under then continuing
One step；
Step 2, the button detection variable quantity summation for all buttons that other are not pressed divided by the number of button calculated are calculated
Amount obtains variation average value Q；
Step 3, the original detection a reference value C that average value Q is added to the button being pressed will be changedoldOn, form new detection a reference value
Cnew；
Step 4, with new detection a reference value CnewCarry out the detection that button is released.Specifically, in the step 4 will by by
Under the real-time detected value F of button subtract new detection a reference value CnewIt is determined as that button discharges when less than button release value B, it is no
Then button is not released.
In one embodiment, the load variation is lit for backlight.
The present invention also protects the electric appliance using the jamproof processing method of above-mentioned membrane keyboard.Including air-conditioning, electromagnetic oven, combustion gas
Water heater, smoke exhaust ventilator, refrigerator and washing machine etc..
The change in detection signal amount of other buttons not being pressed, finds out flat caused by the present invention is changed by computational load
Mean value, and the average value is applied in the change in detection signal amount for the button being pressed, by the error detection signal of load variation
It eliminates, to improve the reliability of button, and the realization method of this method is also relatively simple, and cost is relatively low.
Description of the drawings
With reference to embodiment and attached drawing, the present invention is described in detail, wherein：
Fig. 1 is the flow chart of the present invention.
Specific implementation mode
As shown in Figure 1, the present invention is to load changed scene and be by can correspondingly light backlight after key pressing and cause
Example, to be described in detail.
First, each parameter of touch key-press is illustrated：The effective threshold value A of button（Fixed value）, button release value B（Gu
Definite value）, button a reference value C, detected value D when hand is pressed, detected value E when backlight lights, real-time detected value F are examined when backlight does not work
Measured value G.
In the prior art, when judge the real-time detected value F of button subtract button a reference value C be more than the effective threshold value A of button
When, then it is assumed that by key pressing it is effective, later, when judge the real-time detected value F of button subtract button a reference value C less than button release
When value B, just think that button releases.Therefore, under normal circumstances, hand pushes button when operation, meets formula (F-C)>A, hand
Then meet formula (F-C) when release<B, at this moment touch key-press is normal response.It is likely that there are abnormal conditions, i.e., hand is pressed
After lower, after responding button, backlight is lit, that is, load changes, and power supply has fluctuation, button detection signal to change,
After hand unclamps, real-time detected value F or bigger, it is possible to can not meet formula (F-C)<B eventually leads to button and always can not
Release, button occur abnormal.
But be intended to calculate light backlight after caused button detection variable quantity, i.e. E-G, to eliminate this load variation
Caused influence is more difficult, because it is not invariable, and backlight can not possibly be actively lighted by software come special
It goes to calculate the variation magnitude, because just it can not possibly be allowed to light by somehow or other during using the product by the user.If examining
Worry lights this moment of backlight when hand pushes button and goes to calculate variable quantity and infeasible, because being possible to miss at this time
The variable quantity that handle presses generation is considered as caused by backlight changes.
But common product has several touch key-press, and although the detected value of each button is different, backlight variation
Cause the detected value of each button also different afterwards, obtained by multi-group data test analysis, each button generates variable quantity
It is not much different, there is referentiability.Then, the present invention passes through using after some touch key-press is pressed and lights backlight
Calculate the detection variable quantity summation of other touch key-press not being pressed, then divided by these press bond number, you can obtain a back of the body
Light variation causes button detection variation average value Q, after having some touch key-press to press, variation average value Q is forcibly supplied to it
Former button a reference value ColdOn, i.e., new button a reference value meets formula Cnew=Cold+ Q, the then variation of button detection at this time are（F-
Cnew）, the value very little can meet less than B, the touch key-press will be released at this time, can normal response.It presses every time
When button, the detected value of button is handled using this method, then can effectively eliminate influences caused by backlight lightening.
This method not only limits to a kind of backlight this load, can also eliminate caused by other predictable load variations
Interference signal, by above-mentioned processing method treated touch key-press, reliability has obtained significant raising.
Meanwhile the present invention also protects and uses above-mentioned processing method to realize the jamproof electric appliance of button, these electric appliance packets
Include air-conditioning, electromagnetic oven, gas water-heating furnace, smoke exhaust ventilator, refrigerator and washing machine etc..
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
