Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

With the wide application of touch keys in modern life, it is particularly important to accurately identify the true state of the touch key and respond to operation. However, in the use process of the touch key, when the key is pressed and released, the key is affected by the surrounding environment, such as water drops on the touch key, or the touch key is affected by electromagnetic interference or noise interference, so that the actual state of the touch key is easily misjudged as the key is kept in an unclamped state for a long time, and no response is caused when other key operations are performed, thereby affecting the effective performance of the subsequent other key operations. The invention provides a touch key control method, a device, equipment and a storage medium, which can solve the problem that after a touch key is pressed and released, the key is misjudged to remain in an unclamped state for a long time due to noise interference or other reasons such as residual substances in the key, so that no reaction is caused when other key operations are performed, so that subsequent other key operations can be effectively performed, and the experience effect of a user is improved.

According to an embodiment of the present invention, there is provided a touch key control method embodiment, it being noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order other than that shown or described herein.

In this embodiment, a touch key control method is provided, fig. 1 is a schematic flow chart of the touch key control method according to an embodiment of the present invention, as shown in fig. 1, the flow includes the following steps:

in step S101, when the touch key is in the key-down state, the duration of the touch key being touched is recorded.

In this embodiment, when the touch key is touched, that is, the touch key is pressed, the timer automatically starts to record the corresponding pressing time.

Step S102, judging whether the duration of touching the touch key reaches the preset duration of touching.

In this embodiment, the specific value of the touch preset duration is not limited herein, and is set according to the actual application requirement. For example, the touch preset time period is 40s, which is merely illustrative.

Step S103, when the duration that the touch key is touched reaches the touch preset duration, the touch key is controlled to be in a key release state.

The touch key control method provided by the embodiment of the invention can update the key state after the key is pressed and released, so that other subsequent key operations can be effectively performed, and the problem that no reaction is caused when other key operations are performed because the key is erroneously judged to remain in the unclamped state for a long time due to noise interference or other reasons such as residual substances of the key after the key is pressed and released is solved.

In this embodiment, a touch key control method is provided, fig. 2 is a schematic flow chart of another touch key control method according to an embodiment of the present invention, as shown in fig. 2, the flow includes the following steps:

in step S201, when the touch key is in the key-down state, the duration of the touch key being touched is recorded.

Specifically, in step S201, when the touch key is in the key-down state, the touch key control method further includes:

in step S2011, the touch signal variation is calculated based on the touch signal of the touch key and the reference signal, which is the corresponding touch signal when the touch key is not pressed.

In this embodiment, the reference signal is an average value of the corresponding touch signals when the touch key is not pressed (the touch key is not touched), which is merely used as an example, and the specific value of the reference signal is determined according to the actual application requirement without being limited thereto.

In step S2012, the current key state of the touch key is determined based on the relationship between the touch signal variation and the first touch signal threshold, the first touch signal threshold being greater than the reference signal. Note that the touch keys include resistive touch keys and capacitive touch keys. The resistance type touch key changes the resistance value through the pressure of hands, so that the touch key function is realized; the capacitive touch key can change the voltage of the key by forming capacitance between the hand or other objects capable of carrying charges and the key, thereby realizing the function of touching the key. In the present embodiment, taking a capacitive touch key as an example, the touch key state is determined by the amount of capacitance change generated when the key is touched. The touch key state includes: a key-down state, a key-up state, and a key-down state.

Fig. 3 is a schematic diagram of the touch signal of the present embodiment, and as can be seen from fig. 3, the touch signal variation=touch signal-reference signal. It should be noted that, when the touch key is in the key-down state, the subsequent state of the touch key may be a key-release state or a key-long-press state, where the state is determined based on the touch signal variation, including: if the touch signal variation is not greater than the first touch signal threshold value and lasts for a period of time, the touch key is in a key release state; and if the touch signal variation is larger than the first touch signal threshold, the touch key is in a key long-press state.

Fig. 4 is a schematic flow chart of key release and key long press in this embodiment, taking a capacitive touch key as an example, as can be seen from fig. 4, t2 is an anti-shake time (a first preset duration) of touch key release, C2 is a first touch signal threshold, and the determining flow chart of key release and key long press includes: detecting a touch signal variation Diff after a certain key is pressed; if the Diff of the key is less than or equal to C2 and the time t2 is continued, the key is judged to be released; if the Diff > C2 of the key is detected, the key is judged to be pressed for a long time, and the time is counted for a long time.

Specifically, in the step S2012, the determining the current key state of the touch key based on the relationship between the touch signal variation amount and the first touch signal threshold includes:

and a step a1, judging whether the variation of the touch signal is larger than a first touch signal threshold value.

And a step a2 of recording a first duration in which the touch signal variation is continuously not greater than the first touch signal threshold value when the touch signal variation is not greater than the first touch signal threshold value.

And a step a3 of determining that the current key state of the touch key is a key release state when the first time length is longer than the first preset time length, wherein the first preset time length is the anti-shake time for releasing the touch key.

It should be noted that, in this embodiment, the values of the first touch signal threshold and the first preset duration are not limited in particular, and are determined according to the actual application requirements. For example, the first touch signal threshold is 250F and the first preset duration is 25s, for illustration only.

In this embodiment, when the touch signal variation is greater than the first touch signal threshold, a second period of time during which the touch signal variation is continuously greater than the first touch signal threshold is recorded; and when the second time length is longer than a second preset time length, determining that the current key state of the touch key is a key release state, wherein the second preset time length is the maximum pressing time length of the touch key, and the second preset time length is not longer than the touch preset time length.

It should be noted that, in this embodiment, for the key long-pressed state, a corresponding maximum pressing time length is set, when the second time length of the touch signal variation continuously greater than the first touch signal threshold reaches a second preset time length, the current key state is forcedly updated to be in a key release state, so as to overcome the problem that the key is released after the key is pressed, but the touch signal variation is reduced due to noise interference or other reasons such as residual substances in the key, but the touch signal variation is kept greater than the first touch signal threshold state, i.e. the key is kept in a long-pressed state, so that no reaction is caused when other key operations are performed. Specifically, when the duration of the long-press state meets the maximum-press duration, the corresponding touch signal variation quantity is enabled to meet the key release condition by forcedly updating the key touch signal; when the current key state of the touch key is a key release state, the touch key is controlled to be in the key release state, so that other subsequent key operations can be effectively performed.

Step S202, judging whether the duration of touching the touch key reaches the preset duration of touching. Please refer to step S102 in the embodiment shown in fig. 1 in detail, which is not described herein.

In step S203, when the duration of touching the touch key reaches the touch preset duration, the touch key is controlled to be in the key release state. Please refer to step S103 in the embodiment shown in fig. 1 in detail, which is not described herein.

In this embodiment, when the duration of the touch key being touched does not reach the touch preset duration, a step of calculating the amount of change of the touch signal based on the touch signal and the reference signal of the touch key being touched is performed. Specifically, by setting the determination and the control cycle execution mode of the key release state after the key is pressed, the misjudgment and the misjudgment of the key release state can be reduced, and the more true and accurate touch key release state can be obtained.

In this embodiment, taking a capacitive touch key as an example, determining a key-down state based on a touch signal variation includes: if the touch signal variation is not smaller than the second touch signal threshold value and lasts for a period of time, the touch key is in a key-press state. Fig. 5 is a schematic flow chart of key pressing in the present embodiment, taking a capacitive touch key as an example, as can be seen from fig. 5, t1 is an anti-shake time (a third preset duration) of the touch key pressing, C1 is a second touch signal threshold, and the determining process of the touch key pressing state includes:

step b1, detecting whether the touch key is touched.

And b2, after the touch signal of the touch key is detected, calculating the change amount of the touch signal according to the reference signal.

And b3, when the touch signal variation meets the preset key pressing condition, determining that the touch key is in a key pressing state, wherein the preset key pressing condition is that the touch signal variation is not less than a second touch signal threshold and the duration reaches a third preset duration (Diff is not less than C1 and the duration is t 1), the third preset duration is the anti-shake time of the touch key pressing, and the first touch signal threshold is less than the second touch signal threshold. The reference signal is a touch signal corresponding to a case where the touch key is not pressed (the touch key is not touched), the second touch signal threshold C1 is a touch signal corresponding to a case where the key is pressed (the touch key is touched), the first touch signal threshold C2 is a touch signal corresponding to a case where the touch key is pressed and just released, and the magnitude relation is as follows: the reference signal is less than the first touch signal threshold C2 and less than the second touch signal threshold C1.

It should be noted that, the values of the second touch signal threshold and the third preset duration are not limited in particular, and are set according to the actual requirements. According to the embodiment of the invention, the touch key pressing state can be accurately obtained through judging the touch signal variation and the preset key pressing condition.

In a specific embodiment, taking a capacitive touch key as an example, referring to fig. 6, it should be noted that in the figure, t2 is an anti-shake time (a first preset time period) for releasing the touch key, t3 is a maximum pressing time period (a second preset time period) for touching the key, t4 is a touch preset time period, and C2 is a first touch signal threshold. When the key is pressed, the flow of the touch key control method comprises the following steps:

in step c1, specific values of t3 and t4 are set according to actual requirements, where t3 is equal to or less than t4, for example, t3=30s and t4=40s.

And c2, after a certain key is detected to be pressed, firstly cleaning t2, t3 and t4 for timing, and then detecting the variation Diff of the touch signal.

Step C3, if the Diff > C2 of the key is detected, starting t3 timing and clearing t2 timing, otherwise starting t2 timing and clearing t3 timing.

Step c4, if t2 reaches the preset anti-shake time for releasing the touch key, judging that the key is released; otherwise, t4 timing is performed.

Step c5, if t3 reaches the preset maximum pressing duration of the touch key, clearing t3 time, and forcedly updating the key Baseline value (reference signal) to enable the touch signal variation Diff to be 0, namely enabling the reference signal to be equal to the touch signal, and then re-detecting the touch signal variation Diff; otherwise, t4 timing is performed.

It should be noted that, the key Baseline value is forcedly updated, and the touch signal Finger value of the key is assigned to the reference signal Baseline, that is, baseline=finger, then the touch signal diff=finger-Baseline=0 is detected again, so as to satisfy Diff being less than or equal to C2, and the key release is judged.

Step c6, if t4 reaches the preset touch duration, clearing t2 and t3, forcedly updating the key Baseline value, and then re-detecting the touch signal variation Diff; otherwise Diff is directly re-detected.

It should be noted that, in this embodiment, the key state may also be determined by presetting the number of times of scanning the key, that is, presetting the number of times of scanning the key×scanning interval=duration, which is merely illustrative. In addition, the touch key control method of the embodiment of the invention can be applied to household appliances with touch keys, such as electric fans, electric heaters and the like, and is used for accurately judging and controlling the release of the keys.

In summary, according to the touch key control method of the embodiment of the invention, when the touch key is in the key-down state, the time length of the touch key which is touched is recorded, and the recorded time length of the touch key which is touched and the touch preset time length are judged, so that the touch key is controlled to be in the key-release state when the touch preset time length is reached. The invention can solve the problem that after the key is pressed and released, the key is misjudged to be in an unclamped state for a long time due to noise interference or other reasons such as residual substances in the key, so that no reaction is caused when other key operations are performed, and update processing is performed on the key state after the key is pressed and released, so that the subsequent other key operations can be effectively performed, and the experience of a user is improved.
