Fig. 1 is a flowchart of a key control method according to an embodiment of the present invention, as shown in fig. 1, the method mainly includes the following steps:

s101, obtaining a key pressure value.

In particular, some existing electrical devices or electronic devices are usually provided with a plurality of keys or buttons, and the specific types of the keys in the embodiment of the present invention are not limited, and include touch keys or mechanical keys. It can be understood that by setting the pressure sensing device at the key position, when the user presses the key, the magnitude of the key pressing force, that is, the key pressure value, can be obtained.

S102, determining an adjustment step value according to the key pressure value.

The adjustment step value refers to the numerical variation of the parameter controlled by the key, and it can be understood that the absolute value of the index value of the adjustment step value is herein. According to different types of parameters corresponding to the control of the keys, corresponding adjustment step values are different, and the adjustment step values can be integer values or decimal values, which are not limited by the embodiment of the invention.

Specifically, the adjustment step value may be determined by table lookup or online real-time calculation according to the key pressure value, which is not limited in the embodiment of the present invention. It can be understood that the key pressure values are different, and the corresponding adjustment step values may be the same or different, and the adjustment step values and the key pressure values may be linearly related or may be any functional relationship, which is not limited in the embodiment of the present invention. For example, the larger the key pressure value, the larger the adjustment step value.

S103, obtaining the current value of the parameter controlled by the key, and adjusting the current value of the parameter to the target value according to the adjustment step value.

The parameters corresponding to control may also be different according to the types of the keys, for example, the parameters corresponding to control of the temperature adjusting key are temperature, the parameters corresponding to control of the time adjusting key are time, and the embodiment of the invention is not limited to this. It will be appreciated that the type of values or the range of values of the parameters controlled by the different keys will also be different.

Specifically, the current value of the parameter corresponding to the control of the pressed key is obtained, and then the current value is adjusted to the target value by combining the adjustment step value. For example, the step value is adjusted by adding or subtracting the step value based on the current value to obtain the target value. It should be noted that, the target value may be set in advance by the user, or the value obtained by the user by pressing a key to adjust arbitrarily, which is not limited in the embodiment of the present invention. In addition, adjusting the current value of the parameter to the target value according to the adjustment step value includes, but is not limited to, an addition or subtraction operation, a multiplication or division operation, and the like.

In the process of pressing the key, the key may be pressed for a long time or pressed for a short time, and the value is adjusted based on the current value after the adjustment step value is determined by the detected key pressure value. The process may be to press the key once to perform a numerical adjustment, or continuously perform a numerical adjustment according to a pressure change with an increase of the pressing duration, which is not limited in the embodiment of the present invention. It can be understood that any mode of determining the adjustment step value according to the key pressure value and then adjusting the current value of the parameter to the target value according to the adjustment step value is within the scope of the technical scheme of the embodiment of the invention.

In this embodiment, the key pressure value may be obtained by detecting the pressing force of the key in real time, and then the adjustment step value is determined according to the key pressure value, so that the pressing force of the key and the change amount of the value may be associated, so that the adjustment step value of the value change is adjusted in real time by changing the pressing force of the key, and then the current value of the parameter corresponding to the control of the key and the adjustment step value are further processed to obtain the target value, so that the step value of the parameter adjustment may be adaptively changed for the parameters in different adjustment ranges, so as to shorten the time of parameter adjustment, improve the efficiency of parameter adjustment, and further improve the experience effect of the user.

Optionally, fig. 2 is a flowchart of another key control method according to an embodiment of the present invention, as shown in fig. 2, on the basis of fig. 1, an adjustment step value is determined according to a key pressure value, including: comparing the key pressure value with a plurality of preset pressure ranges in a preset database, and determining the preset pressure range in which the key pressure value is located; and determining an adjustment step value according to the preset pressure range in which the key pressure value is positioned, wherein the adjustment step value corresponds to the preset pressure ranges one by one and is positively correlated with the average pressure value corresponding to the preset pressure ranges. Therefore, the control method mainly includes the steps of:

s201, obtaining a key pressure value.

S202, comparing the key pressure value with a plurality of preset pressure ranges in a preset database, and determining the preset pressure range in which the key pressure value is located.

The preset database can be preset by a user or inside the system, and is different according to different parameters corresponding to control of specific keys. It can be understood that, according to the difference of the adjustment ranges of the parameters controlled by the keys and the difference of the adjustment precision of the parameters, the number of the preset pressure ranges in the corresponding preset library is also different, which is not limited by the embodiment of the present invention, and can be selectively set by a person skilled in the art according to the actual requirements.

Specifically, a preset database of key pressure values is pre-established, the preset database comprises a plurality of preset pressure ranges, and then the obtained key pressure values are respectively compared with the preset pressure ranges one by one, so that the preset pressure range in which the key pressure values are located can be determined. It can be understood that the preset pressure range is composed of a pressure lower limit value and a pressure upper limit value, and the multiple preset pressure ranges are not overlapped, and meanwhile, the sizes of the multiple preset pressure ranges can be the same or different, the embodiment of the invention is not limited to the above, and the preset pressure ranges can be set according to actual conditions. For example, the preset database includes a plurality of preset pressure ranges of (0 n,0.5 n), [0.5n,0.8 n), [0.8n,1.2 n), [1.2n,1.6 n), [1.6n,2 n), [2n,10 n), and the like.

S203, determining an adjustment step value according to a preset pressure range where the key pressure value is located, wherein the adjustment step value corresponds to the preset pressure ranges one by one, and the average pressure values corresponding to the preset pressure ranges are positively correlated.

Each preset pressure range corresponds to an adjustment step value, so that after the preset pressure range where the key pressure value is located is determined, the adjustment step value of the parameter corresponding to the control of the key at the moment, which needs to be adjusted and changed, can be further determined. The average pressure value corresponding to the preset pressure range can be determined according to the pressure lower limit value and the pressure upper limit value of the preset pressure range, if the average pressure value is larger, the adjustment step value corresponding to the preset pressure range is larger, and if the average pressure value is smaller, the adjustment step value corresponding to the preset pressure range is smaller. Further, the larger the key pressure value is, the larger the adjustment step value is, the smaller the key pressure value is, and the smaller the adjustment step value is, so that the size of the adjustment step value can be changed by changing the magnitude of the force pressing the key.

S204, obtaining the current value of the parameter controlled by the key, and adjusting the current value of the parameter to the target value according to the adjustment step value.

In this embodiment, the key pressure value can be obtained by detecting the pressing force of the key in real time, and then the obtained key pressure value is respectively compared with a plurality of preset pressure ranges one by one to determine the preset pressure range in which the key pressure value is located at the moment, and the current value of the control parameter corresponding to the key is adjusted according to the adjustment step value determined by the preset pressure range, so that the value of the parameter reaches the target value, the parameter adjustment efficiency is improved, and the experience effect of the user is further improved.

It should be noted that, the adjustment step value is determined according to the preset pressure range where the key pressure value is located, at this time, the key may be pressed for a long time or pressed for a short time, so long as the detected key pressure value meets the preset requirement, the current value is adjusted according to the determined adjustment step value, and it can be understood that, once the key is pressed, the value of the parameter controlled by the key is adjusted once.

For example, the parameter corresponding to the control of the key is temperature, the adjustable range of the corresponding temperature is (0 ℃ and 220 ℃), each pair of increasing keys corresponding to the temperature is pressed once, by collecting the corresponding key pressure values in the pressing process, it can be determined that the preset pressure ranges where the key pressure values are located are determined by comparing with a plurality of preset pressure ranges in a preset database, for example, 20 ℃, the current temperature value is known to be 100 ℃, and the temperature value is adjusted to be 120 ℃ after the key is pressed. It should be noted that, since the pressure value cannot be kept completely constant during the pressing of the key by the user, the obtained key pressure value may be the maximum key pressure value during each key pressing.

Optionally, fig. 3 is a flowchart of a control method of a key according to another embodiment of the present invention, as shown in fig. 3, on the basis of fig. 1, an adjustment step value is determined according to a key pressure value, including: determining a step length adjustment speed value according to the key pressure value; calculating a first duration for which the key pressure value remains unchanged; and calculating an adjustment step value in real time according to the step adjustment speed value and the first duration, wherein the adjustment step value is a mathematical function related to the step adjustment speed value and the first duration. Therefore, the control method mainly includes the steps of:

s301, obtaining a key pressure value.

S302, determining a step length adjustment speed value according to the key pressure value.

The step adjustment speed value refers to an adjustment step value corresponding to a fixed time, for example, the step adjustment speed value is increased by 5 every 100ms, i.e. the step adjustment speed value is 5/100ms, which is not limited in the embodiment of the present invention.

Specifically, the step adjustment speed value may be determined by table lookup or online real-time calculation according to the key pressure value, which is not limited in the embodiment of the present invention. It can be understood that the key pressure values are different, and the corresponding step adjustment speed values may be the same or different, and the step adjustment speed values and the key pressure values may be linearly related or may be any functional relationship, which is not limited by the embodiment of the present invention. For example, the larger the key pressure value, the larger the step adjustment speed value.

S303, calculating the first duration time for which the key pressure value is kept unchanged.

Specifically, in the process of pressing the key, the key pressure value may change in real time, and different key pressure values may be timed by a timing device in the control system to obtain a first duration time for which the key pressure value remains unchanged.

S304, calculating an adjustment step value in real time according to the step adjustment speed value and the first duration, wherein the adjustment step value is a mathematical function related to the step adjustment speed value and the first duration.

Specifically, the adjustment step value is a mathematical function of the step adjustment speed value and the first duration, including but not limited to, adjustment step value = step adjustment speed value. For example, in the process of pressing the key, the key pressure value is kept unchanged all the time, the step length adjustment speed value corresponding to the key pressure value is determined to be 5/100ms through table lookup, and meanwhile, the duration of the key pressure value kept unchanged is 200ms, so that the adjustment step length value of the parameter corresponding to the control of the key can be calculated to be 10.

It can be understood that if the key pressure value changes in real time during the continuous pressing process of the key, the corresponding step adjustment speed value also changes in real time, and the corresponding adjustment step value corresponding to different time periods can be determined by calculating the corresponding first duration time for different key pressure values, that is, in this process, the adjustment step value of the parameter corresponding to the control of the key changes, and the specific change trend is positively correlated with the key pressure value.

S305, obtaining the current value of the parameter controlled by the corresponding key, and adjusting the current value of the parameter to the target value according to the adjustment step value.

Specifically, according to the adjustment step value obtained by calculation in the above steps, the current value is increased or decreased according to the change trend of the adjustment step value until the key is pressed, and the parameter value controlled by the key correspondingly reaches the target value. It will be appreciated that in this process, the speed of change of the value of the parameter controlled by the key is the same as the step adjustment speed value, and the step adjustment speed value is positively correlated with the key pressure value, so that the greater the key pressure value, the faster the speed of change of the value of the parameter controlled by the key, and the smaller the key pressure value, the slower the speed of change of the value of the parameter controlled by the key.

For example, if a certain parameter is to be adjusted from 1 to 720, the adjustment speed is +1/100ms if the user touches the device lightly, and if the finger pressing force is increased, the adjustment speed is automatically adjusted to +15/100ms or higher, so that the parameter can be quickly adjusted, the parameter adjustment time is shortened, the operation efficiency is improved, and the experience effect of the user is further improved.

In this embodiment, the key pressure value may be obtained by detecting the pressing force of the key in real time, then determining the step length adjustment speed value for the key pressure value, and meanwhile, calculating the first duration time for which the key pressure value remains unchanged, so that the adjustment step length value may be calculated in real time according to the specific functional relationship between the step length adjustment speed value and the first duration time, and further, the current value of the key corresponding to the control parameter may be adjusted, so that the value of the parameter reaches the target value, the efficiency of parameter adjustment is improved, and further, the experience effect of the user is improved.

Optionally, fig. 4 is a flowchart of a control method of a key according to another embodiment of the present invention, as shown in fig. 4, on the basis of fig. 3, a step adjustment speed value is determined according to a key pressure value, including: comparing the key pressure value with a plurality of preset pressure ranges in a preset database, and determining the preset pressure range in which the key pressure value is located; and determining a step length adjusting speed value according to a preset pressure range in which the key pressure value is positioned, wherein the step length adjusting speed value corresponds to the preset pressure ranges one by one and is positively correlated with the average pressure value of the preset pressure ranges. Therefore, the control method mainly includes the steps of:

s401, obtaining a key pressure value.

S402, comparing the key pressure value with a plurality of preset pressure ranges in a preset database, and determining the preset pressure range in which the key pressure value is located.

The preset database can be preset by a user or inside the system, and is different according to different parameters corresponding to control of specific keys. It can be understood that, according to the difference of the adjustment ranges of the parameters controlled by the keys and the difference of the adjustment precision of the parameters, the number of the preset pressure ranges in the corresponding preset library is also different, which is not limited by the embodiment of the present invention, and can be selectively set by a person skilled in the art according to the actual requirements.

S403, determining a step adjustment speed value according to a preset pressure range in which the key pressure value is located, wherein the step adjustment speed value corresponds to the preset pressure ranges one by one and is positively correlated with an average pressure value of the preset pressure ranges.

Each preset pressure range corresponds to a step adjustment speed value, so that after the preset pressure range where the key pressure value is located is determined, the step adjustment speed value corresponding to the parameter step adjustment value controlled by the key at the moment, in other words, the speed of parameter adjustment change, can be further determined.

In addition, the average pressure value corresponding to the preset pressure range can be determined according to the pressure lower limit value and the pressure upper limit value of the preset pressure range, if the average pressure value is larger, the adjustment step value corresponding to the preset pressure range is larger, and if the average pressure value is smaller, the adjustment step value corresponding to the preset pressure range is smaller. Further, the larger the key pressure value is, the larger the adjustment step value is, the smaller the key pressure value is, and the smaller the adjustment step value is, so that the size of the adjustment step value can be changed by changing the magnitude of the force pressing the key.

S404, calculating the first duration time for which the key pressure value is kept unchanged.

S405, calculating an adjustment step value in real time according to the step adjustment speed value and the first duration, wherein the adjustment step value is a mathematical function related to the step adjustment speed value and the first duration.

S406, obtaining the current value of the parameter controlled by the key, and adjusting the current value of the parameter to the target value according to the adjustment step value.

In this embodiment, the key pressure value may be obtained by detecting the pressing force of the key in real time, and then comparing the obtained key pressure value with a plurality of preset pressure ranges one by one, to determine the preset pressure range in which the key pressure value is located at this time, and determine the step adjustment speed value according to the preset pressure range, and at the same time, calculate the first duration time in which the key pressure value remains unchanged, further calculate the step adjustment speed value and the first duration time to obtain the adjustment step value at this time, and then adjust the current value of the control parameter corresponding to the key, so that the value of the parameter reaches the target value, improving the efficiency of parameter adjustment, and further improving the experience effect of the user.

Thus, the method comprises in particular the following steps:

s501, obtaining a key pressure value.

S502, acquiring a key touch signal, and determining a parameter corresponding to control of a key and an adjustable range of the parameter according to the key touch signal.

The key touch signal is triggered and generated when the key is just pressed or touched, and it can be understood that the key touch signal refers to an effective key touch signal, and the effective key touch signal can be determined by comparing a key pressure value with a preset pressure value, or by comparing the duration of the existence (i.e. greater than zero) of the key pressure value with a preset time. The key touch signal may be an analog signal or a digital signal, which is not limited in the embodiment of the present invention.

Specifically, by acquiring the key touch signal and performing further processing analysis, the key type corresponding to the key touch signal and the parameter corresponding to the control of the key can be determined, and meanwhile, the adjustable range of the parameter can also be determined.

S503, determining a preset database corresponding to the parameters according to the adjustable range of the parameters and the key pressure value.

It can be understood that the adjustable range of the parameters is not different according to the different parameters corresponding to the keys, in addition, the adjustment precision of different parameters is different, so that the preset databases corresponding to different key pressure values are different comprehensively, and the person skilled in the art can set according to the actual situation. After the parameters and the adjustable ranges of the parameters corresponding to the control of the keys are determined according to the key touch signals, a preset database to be called can be determined through the adjustable ranges of the parameters and the key pressure values, so that corresponding information can be read for different key pressure values later.

S504, comparing the key pressure value with a plurality of preset pressure ranges in a preset database, and determining the preset pressure range in which the key pressure value is located.

Thus, the method essentially comprises the steps of:

s701, acquiring a key touch signal, and judging that the duration of the key touch signal exceeds a first preset time.

The specific value of the first preset time may be set according to the actual situation, which is not limited in the embodiment of the present invention.

Specifically, aiming at the existing keys with multiple touches, the user may have the condition of no touch, so that when the key touch signal is acquired, the duration of the key touch signal is compared with the first preset time, whether the key touch signal is an effective touch signal can be further judged, the normal operation of the equipment is prevented from being influenced by the false touch of the user, the reliability of the product is ensured, and the use experience of the product is improved.

S702, determining a numerical value change rule of a parameter corresponding to control of the key according to the key touch signal, wherein the numerical value change rule comprises increase or decrease.

It will be appreciated that typically the product will include multiple types of keys, such as temperature keys or time keys, etc., while for the same parameter type of keys there will be further differentiation of increasing or decreasing, such as temperature increase keys, or temperature decrease keys, etc. In this way, when different keys are pressed, the generated key touch signals are different, and the numerical variation rule of the parameters controlled by the keys corresponding to the keys can be determined according to the key touch signals obtained through actual detection, including increasing or decreasing.

For example, when the user presses the temperature increasing key, a key touch signal is generated, and the parameter corresponding to the control of the key can be determined to be temperature through further analysis and processing of the key touch signal, and the value of the temperature needs to be increased.
