In the embodiment of the disclosure, hardware starts scanning of the touch key at intervals of a period of time under a low-frequency clock and then takes a value to judge whether to exit from the low-power-consumption mode, the process does not need CPU participation, the overall power consumption of the touch key is obviously reduced, the method can reduce about 50% of power consumption compared with the method that software participates in the low-power-consumption mode through testing, once a touch key channel is found through scanning to be triggered to exit from the low-power-consumption mode, and compared with the method that software is used, the response speed of the touch key is improved. In addition, according to the embodiment of the disclosure, when the operation of the low-frequency oscillator reaches the preset duration, the operating frequency of the touch key module is configured to be the first operating frequency, and the first operating frequency is set to be higher than the second operating frequency, so that the speed of judging whether the touch occurs by the hardware can be increased.
In the embodiment of the present disclosure, if it is determined that the scan count value of any key is greater than the preset scan count value, it may be determined that a touch occurs, and in this case, the embodiment of the present disclosure may control the touch key module to exit the low power consumption mode, and wake up the control component to improve the efficiency of scanning the touch key, and perform subsequent operations, which is described in the following exemplary description.
In one possible implementation, as shown in fig. 3, after the touch key module exits the low power consumption mode, the method may further include:
step S22, determining a count difference between the scan count value and the preset scan count value;
step S23, determining an environment judgment parameter according to the ratio of the counting difference value to a preset counting difference value, wherein the preset counting difference value is the difference of scanning count values of the touch key module before and after the interference of the radio frequency interference source under the condition of no touch;
and step S24, determining the environment parameter of the touch key module according to the environment judgment parameter.
Through the method, the embodiment of the disclosure can determine the count difference value between the scan count value and the preset scan count value, determine the environment judgment parameter according to the ratio of the count difference value to the preset count difference value, determine the environment parameter where the touch key module is located according to the environment judgment parameter, and obtain the located environment information.
The method comprises the steps that all touch keys can be scanned before and after the interference of a radio frequency interference source to obtain an average value of scanning count values of the touch keys before and after the interference, and the difference of the average value is used as the difference of the scanning count values of the touch key module before and after the interference of the radio frequency interference source; or taking the maximum value of the difference of the scanning count values of the touch keys before and after the interference as the difference of the scanning count values of the touch key module before and after the interference of the radio frequency interference source.
The method for acquiring the environmental parameters of the embodiment of the disclosure can be executed by the control component.
In one example, the radio frequency interference source may be a 10W power interphone, the 10W power interphone is an electronic device with strong radio frequency interference, and the capability of resisting radio frequency interference of other electronic devices may be measured by the 10W power interphone. For example, a 10W power interphone can generate a huge radio frequency radiation interference to the touch key module, and the radio frequency anti-interference capability of the touch key is judged through the change of the count value of the touch key and the actual response effect.
In a possible implementation, the step S22 of determining the count difference between the scan count value and the preset scan count value may include:
if the touch key module is in a condition that the scanning count value is reduced after the touch occurs, subtracting the preset scanning count value from the scanning count value to obtain a count difference value; or
And if the touch key module is in a condition that the scanning count value is increased after the touch occurs, subtracting the scanning count value from the preset scanning count value to obtain the count difference value.
Due to the design reason of the touch key module by manufacturers, after the keys are touched by hands, the count value of some touch key modules is increased, and the count value of some touch key modules is reduced. The embodiment of the disclosure adaptively calculates the counting difference value for the touch key module corresponding to the situation that the scanning count value is decreased after the touch occurs and the situation that the scanning count value is increased after the touch occurs, and can improve the accuracy and the flexibility.
In a possible implementation, the step S22 of determining the count difference between the scan count value and the preset scan count value may include:
and under the condition that the counting difference value is larger than zero, determining the counting difference value of the scanning counting value and the preset scanning counting value.
According to the embodiment of the disclosure, the accuracy of obtaining the environmental information can be improved by determining the counting difference value between the scanning count value and the preset scanning count value under the condition that the counting difference value is greater than zero.
In a possible implementation manner, the step S23 of determining the environment determination parameter according to the ratio of the count difference to a preset count difference may include:
and taking the ratio of the counting difference value and a preset counting difference value as an environment judgment parameter.
For example, the environment determination parameter can be obtained by equation 1:
formula 1 where D is S/Ts
Wherein D represents an environment determination parameter, S represents a count difference, and Ts represents a preset count difference.
In a possible implementation manner, the step S24 of determining the environment parameter where the touch key module is located according to the environment judgment parameter may include:
determining the environmental parameters of the touch key module according to the environmental judgment parameters and a preset environmental parameter discrimination table,
the preset environment parameter discrimination table comprises an environment judgment parameter or a corresponding relation between an environment judgment parameter range and a plurality of environment parameters, and the environment parameters comprise at least one of temperature, humidity, water level height, electromagnetic interference strength and the like.
The embodiment of the present disclosure does not limit the specific form of the preset environment parameter determination table, does not limit the specific corresponding relationship between the environment determination parameter or the environment determination parameter range included in the preset environment parameter determination table and the plurality of environment parameters, does not limit the type and number of the environment parameters, and can be set by a person skilled in the art according to actual conditions and needs. For example, different environmental parameters may correspond to different environmental judgment parameters or environmental judgment parameter ranges, and corresponding environmental parameters may be determined from the environmental parameter discrimination table according to the current environmental judgment parameter or the environmental judgment parameter range in which the current environmental judgment parameter is located.
For example, when the touch key module is touched by a human hand to decrease the count value, for a touch key in an environment without a radio frequency interference source and without a touch (for example, the touch key may be packaged by a 5mm acrylic plate), the preset scan count value is, for example, 5000 to 5010, the count value of the intercom interference touch key is 4500 to 4510, that is, the current reference value is about 5000, and therefore the preset count difference Ts after the intercom interference is 5000-; taking water level height detection as an example, the count difference between the scan count value of the touch key at the moment when water just touches the touch key, the scan count value of the touch key is in the middle of the touch key, and the scan count value of the touch key at the moment when the water just touches the touch key is 3 times higher than the preset scan count value can be tested in advance, for example, if the count difference S1 between the scan count value of the touch key just touches the touch key and the preset scan count value is 50, the count difference S2 between the scan count value of the touch key and the preset scan count value is 80, and the count difference S3 between the scan count value of the touch key and the preset scan count value when the water is not touching the touch key is 110, then the environment determination parameter D1 is S1 ÷ 500 × 100% ═ 10%, D2 is S2 ÷ 500 × 100% ═ 16, D3 is S3 ÷ 500 × 100 ═ 22% according to formula 1, in the electronic device, the height of the touch key is fixed, the corresponding relationship between the environment determination parameter and the height of the touch key can be determined in advance and stored in the preset environment determination table, when flood or other water overflows the electronic equipment, the water level height can be obtained according to the calculated environment judgment parameter and the preset environment parameter discrimination table.
The example of determining the water level height is given above, and determination of other environmental parameters is similar to the above, and details are not described herein, but of course, the embodiment of the disclosure is not limited to the aforementioned environmental parameters, and may also include other environmental parameters, for example, a temperature change trend, and the like.
