Detailed Description
The following description of the technical solutions in the embodiments of the present invention will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. 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.
[ First embodiment ]
Referring to fig. 1, a first embodiment of the present invention provides a reset control method for a touch key. The reset control method of the touch key comprises the following steps: acquiring an actual capacitance value of a touch key in real time; controlling the touch key to execute a reference capacitance value resetting operation according to the relation between the actual capacitance value and the capacitance noise value under the condition that the actual capacitance value is smaller than a key threshold value; wherein the key threshold is greater than the capacitance noise value.
It can be understood that, under the condition that the actual capacitance value is smaller than the key threshold, whether the use environment where the touch key is located changes can be judged according to the relation between the actual capacitance value and the capacitance noise value, so that when the use environment of the touch key changes, the touch key is controlled to execute the reference capacitance value resetting operation, the problem that the reference capacitance value of the touch key is influenced by the use environment to change, and the touch capacitance of a finger cannot trigger a corresponding air conditioner control instruction, so that the touch key of the display panel is insensitive or the touch key cannot respond is avoided.
For example, when the user's finger does not touch the touch key, the actual capacitance value is the reference capacitance value. When electromagnetic interference exists around the display panel, the actual capacitance value changes in a waveform on the basis of the reference capacitance value, and the peak value of the waveform is the noise capacitance value. When the user touches the touch key, the actual capacitance value is the sum of the reference capacitance value and the finger capacitance.
Further, when the actual capacitance value is smaller than the key threshold, controlling the touch key to execute the reference capacitance value reset operation according to the relation between the actual capacitance value and the capacitance noise value comprises: if the actual capacitance value is larger than the capacitance noise value, acquiring the duration time when the actual capacitance value is larger than the capacitance noise value, and recording the duration time as a first duration time; and controlling the touch key to execute a reference capacitance value resetting operation according to the first time length.
It can be understood that, in the case that the actual capacitance value is smaller than the key threshold, if the actual capacitance value is longer than the capacitance noise value, the reference capacitance value of the touch key is raised, so that the touch key is insensitive or the touch key cannot respond. Therefore, in the case where the actual capacitance value is larger than the capacitance noise value, it is necessary to monitor the duration for which the actual capacitance value is larger than the capacitance noise value.
Further, controlling the touch key to execute the reference capacitance value resetting operation according to the first time length includes: and if the first time length is equal to a first time length threshold value, resetting the current reference capacitance value of the touch key to an initial reference capacitance value, and resetting the first time length.
It can be understood that if the duration of the actual capacitance value being greater than the capacitance noise value is equal to the first time threshold, it is indicated that the current reference capacitance value of the touch key has been raised, so that a reference capacitance value resetting operation needs to be performed on the touch key, and the current reference capacitance value of the touch key is reset to the initial reference capacitance value, so as to ensure that the touch key can detect the touch capacitance of the finger, and trigger a corresponding air conditioner control instruction according to the touch capacitance of the finger. After the current reference capacitance value of the touch key is reset to the initial reference capacitance value, the reset operation is completed, so that the first time is cleared to zero.
Further, in the process of obtaining the first duration, the reset control method of the touch key further includes: and if the actual capacitance value is smaller than or equal to the capacitance noise value, resetting the first duration.
It can be understood that, in the process of obtaining the first duration, if the actual capacitance value is less than or equal to the capacitance noise value, it is indicated that the current actual capacitance value has recovered to be normal, and it is not necessary to continuously accumulate the first duration, so that the first duration is cleared.
Further, the reset control method of the touch key further comprises the following steps: under the condition that the actual capacitance value is larger than or equal to the key threshold value, acquiring the duration time that the actual capacitance value is larger than or equal to the key threshold value, and recording the duration time as a second duration time; and controlling the touch key to execute the reference capacitance value resetting operation according to the second duration.
It can be understood that if the actual capacitance value is greater than or equal to the key threshold, it is determined that the touch key is pressed. The duration of the pressed touch key can be known by acquiring the duration that the actual capacitance value is greater than or equal to the key threshold, so that the intention of the user to press the touch key at the time can be distinguished according to the duration of the pressed touch key, and whether the reference capacitance value is reset or a corresponding air conditioner control instruction is executed is judged.
Further, controlling the touch key to execute the reference capacitance value resetting operation according to the second duration includes: and if the second time length is equal to a second time length threshold value, resetting the current reference capacitance value of the touch key to an initial reference capacitance value, and resetting the second time length.
It can be understood that if the second duration is equal to the second duration threshold, it is determined that the user presses the touch key for the long press operation at this time, so as to reset the reference capacitance value, so that the current reference capacitance value of the touch key is reset to the initial reference capacitance value, and the second duration is cleared.
Further, after the touch key is powered on, if the actual capacitance value is smaller than the key threshold, the duration that the actual capacitance value is smaller than the key threshold is obtained and is recorded as a third duration; and if the third duration is equal to a third duration threshold, resetting the current reference capacitance value of the touch key to an initial reference capacitance value, and resetting the third duration.
It will be appreciated that after the touch key is powered up, if the actual capacitance value is less than the key threshold, it is determined that no key has been pressed. By acquiring the duration that the actual capacitance value is smaller than the key threshold, the current reference capacitance value of the touch key can be reset to the initial reference capacitance value under the condition that the third duration is equal to the third duration threshold, so that the automatic reset of the reference capacitance value of the touch key is realized, and the user does not need to manually trigger the reset operation of the reference capacitance value of the touch key.
Further, the reset control method of the touch key further comprises the following steps: acquiring the use environment and the corresponding resolution of the touch key in real time; and adjusting the key threshold according to the resolution.
It can be understood that by acquiring the use environment and the corresponding resolution of the touch key in real time, when the use environment of the touch key changes, the key threshold can be adjusted according to the resolution corresponding to the use environment, so that the problem that the key is insensitive due to the fact that a set of fixed key threshold is not suitable after the use environment changes is avoided.
For example, the display panel key determines whether the corresponding touch key is pressed according to the capacitance change of the touch key. Each touch key has a corresponding touch threshold, the touch threshold is a capacitance value, when a user's finger touches the touch key, if the capacitance value of the touch key is larger than the touch threshold, the line controller confirms that the user's finger touches the touch key, and if the capacitance value of the touch key is smaller than the touch threshold, the line controller considers that the touch key is not pressed.
The touch capacitance value of the display panel is continuously reduced due to the change of the use environment, the bad use habit of the user, the aging and damage of the display panel. When the capacitance value of the display panel key is too small and cannot reach the set threshold value, the phenomenon that the touch of the display panel key is insensitive or the touch is completely failed occurs, and great trouble is caused to users.
In one implementation, the touch chip automatically recognizes a value of another resolution to be performed after detecting a change in the use environment. Environmental changes are handled by setting a set of key thresholds at various resolutions which may change, and the situation that the key is insensitive due to inapplicability of the key thresholds after the changes can be avoided.
[ Second embodiment ]
The second embodiment of the invention provides a reset control device for a touch key. Referring to fig. 2, the reset control apparatus 200 of the touch key includes: the acquisition module 210 and the control module 220. The acquiring module 210 is configured to acquire an actual capacitance value of the touch key in real time; the control module 220 is configured to control the touch key to execute a reference capacitance value reset operation according to the relationship between the actual capacitance value and the capacitance noise value when the actual capacitance value is smaller than a key threshold; the key threshold is greater than the capacitance noise value.
In a specific embodiment, the obtaining module 210 and the control module 220 are mutually matched to implement the reset control method of the touch key provided in the first embodiment, and the same technical effects can be achieved, so that repetition is avoided, and detailed description is omitted here.

The air conditioner comprises a display panel provided with touch keys, and the air conditioner executes the reset control method of the touch keys provided by the first embodiment and executes reference capacitance value reset operation on the touch keys of the display panel.
