Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 is a flowchart illustrating a screen static electricity detection control method according to a preferred embodiment of the present invention shown in fig. 1. The screen static electricity detection control method comprises the following steps:
step S100, when the screen of the mobile terminal is lighted, starting a preset voltage detection module and starting to acquire a voltage signal of the screen surface.
Preferably, the step S100 further includes, before:
and S001, presetting a voltage detection module for detecting a voltage signal on the surface of the screen of the mobile terminal.
In specific implementation, when the mobile terminal is in a normal working state, a normal power supply voltage exists on the screen, and when static electricity exists in the environment (for example, when the mobile terminal is placed in a pocket of a user and contacts with clothes and cloth to generate static electricity), the generated static voltage can be superposed on the power supply voltage, and when the static voltage is superposed on a certain value, certain damage is caused to an internal chip or a circuit of the mobile terminal. Therefore, in order to better detect the voltage value of the screen surface of the mobile terminal, the invention is provided with a voltage detection module in advance, which is used for acquiring the voltage signal of the screen surface of the mobile terminal and better acquiring the voltage signal generated by the electrostatic environment.
Further preferably, the step S100 specifically includes:
step S101, the mobile terminal receives an operation instruction of a user and lights a screen;
and step S102, starting the preset voltage detection module and starting to acquire the voltage signal of the screen surface.
When the mobile terminal is implemented specifically, the mobile terminal receives an operation instruction of lighting the screen by a user, and the screen is lighted. Such as a user waking up the screen of the mobile terminal using a key of the mobile terminal, fingerprint recognition, or double-clicking the screen. After the screen is lighted, the preset voltage detection module acquires a voltage signal on the surface of the screen, so that the voltage detection module can work only when the screen is in a lighting working state. The reason is that when the screen is in the dormant black screen, the screen does not have a power supply voltage, and a voltage signal generated by static electricity is small and is not enough to damage the mobile terminal, so that the voltage detection module does not work when the screen is in the dormant black screen.
Step S200, dividing the voltage signal into a plurality of sections according to a preset time length, and calculating the voltage signal difference between two adjacent sections in the continuous preset section.
Preferably, the step S200 specifically includes:
step S201, presetting a time length which is used as a unit quantity for dividing the voltage signal;
step S202, dividing the voltage signal acquired by the voltage detection module into a plurality of sections according to a preset time length;
step S203, calculating a voltage signal difference value of the voltage signals between two adjacent segments in the continuous preset segment, and obtaining the voltage signal difference value.
In specific implementation, in order to better judge the degree of change of the voltage signal acquired by the voltage detection module, the voltage signal acquired by the voltage detection module needs to be divided into a plurality of segments according to a preset time length. The preset time length can be set automatically according to actual needs. For example, the acquired voltage signal is described as a function f (t) of time t, the preset time length is t1, the time for starting the voltage detection module is t0, and the current time is t2, the voltage signal acquired by the voltage detection module will be divided into the following segments:
f(t), t0≤t≤t1；
f(t)， t1≤t≤2*t1;
f(t)， 2*t1≤t≤3*t1;
f(t)， 3*t1≤t≤4*t1;
……
f(t)， t2-t1≤t≤t2。
after dividing into a plurality of segments, a voltage signal difference is calculated for the voltage signals between two adjacent segments in the continuous preset segment. The continuous preset section can be set according to actual needs. Preferably, the continuous preset segment is 5 continuous segments, that is, the voltage signals between two adjacent segments are differenced in the 5 continuous segments. For example, when required
（1）f(t)， t2-t1*2≤t≤t2-t1；
（2）f(t)， t2-t1≤t≤t2。
When the two voltage signals are different, the voltage signal of the (1) th section is shifted to the right by t1, or the voltage signal of the (2) th section is shifted to the left by t1, so that the two voltage signals are at the same time point, and then the voltage signal values of the corresponding time points are subtracted to obtain a voltage signal difference. Similarly, the voltage signal difference between two adjacent segments in 5 consecutive segments is determined by the method described above. According to the method, the voltage signal acquired by the voltage detection module is divided in equal time periods, and the voltage signal difference between two adjacent sections in the continuous preset section is calculated, so that the change degree of the voltage signal can be judged visually, whether the voltage generated by static electricity can damage the mobile terminal or not can be judged conveniently, and convenience is provided for users.
Step 300, when the voltage signal difference values between two adjacent segments in the continuous preset segment are all smaller than a preset threshold value, the voltage detection module is closed.
Preferably, the step S300 specifically includes:
step S301, comparing the obtained voltage signal difference value with the preset threshold value;
step S302, when the voltage signal difference values are all smaller than the threshold value, judging that the voltage signal change of the continuous preset segment is smaller, and closing the voltage detection module.
During specific implementation, the obtained voltage signal difference value is compared with a preset threshold value, and the preset threshold value can be set automatically according to actual requirements. And when the voltage signal difference values are smaller than the threshold value, namely the voltage signal difference values between two adjacent sections in the 5 continuous sections are smaller than the threshold value, judging that the voltage signal change of the continuous preset section is smaller and is almost similar to a straight horizontal straight line, and closing the voltage detection module. Preferably, after the voltage detection module is turned off, the voltage detection module is turned on again after a preset time interval, and continues to acquire the voltage signal of the screen surface. The preset time interval is 2 seconds, and the automatic setting can be carried out according to actual requirements. And when the voltage change degree is small, namely the voltage signal difference value between two adjacent sections in the 5 continuous sections is smaller than the threshold value, the voltage detection module is closed, the working time of the voltage detection module is shortened, the power consumption of the mobile terminal is reduced, and the electric energy is saved. When the voltage detection module is closed for 2 seconds, the voltage detection module can be restarted to continuously acquire the voltage signal on the surface of the screen of the mobile terminal, so that the problem that the voltage change is too large and unknown due to the fact that the voltage detection module is closed for a long time is solved, and convenience is provided for a user.
Based on the embodiment, the invention also discloses a mobile terminal. As shown in fig. 2, includes: a processor (processor)10, a storage device (memory)20 connected to the processor; the processor 10 is configured to call program instructions in the storage device 20 to execute the method provided in the foregoing embodiments, for example, to execute:
