Problems solved by technology

[0005] The defect of the prior art is that the metal shrapnel for detecting the insertion of the SD card is located in the card holder, resulting in a larger size of the card holder
In addition, the elasticity of metal shrapnel will inevitably change after repeated use, which will affect the detection of SD card insertion

Embodiment 2

[0062] The embodiment of the present invention also provides a mobile terminal, such as Figure 4 As shown, the mobile terminal includes a processor 10, and a memory 20 connected to the processor 10;

[0063] Described memory 20 is stored with computer program, and when this computer program is executed by processor 10, realizes as the step of any one embodiment mobile terminal SD card detection frequency control method;

[0064] The processor 10 is used to call the program instructions in the memory to execute the steps of the method for controlling the detection frequency of the mobile terminal SD card in any one of the above embodiments. Specifically as above.

Embodiment 3

[0066] An embodiment of the present invention is a storage medium, wherein the storage medium stores a computer program, and when the computer program is executed by the processor 10, the steps of any one of the methods for controlling the detection frequency of the mobile terminal SD card are implemented, specifically as described above.

[0067] In summary, the mobile terminal and its SD card detection frequency control method and storage medium provided by the present invention, the method is by setting a proximity sensor near the card slot, and starting the proximity sensor to detect the distance change of the object in front of it; When the proximity sensor detects that the distance changes from the first preset value to the second preset value, or from the second preset value to the first preset value, the SD card is judged by sending instructions to the SD card at a higher first frequency. Whether it is in place, and continue to execute for 10 seconds; otherwise, it is j...

Abstract

The invention discloses a mobile terminal and its SD card detection frequency control method and a storage medium. The method sets a proximity sensor near the card slot and starts the proximity sensor to detect the distance change of the object in front; when the proximity sensor detects If the distance changes from the first preset value to the second preset value, or changes from the second preset value to the first preset value, it is judged whether the SD card is in place by sending instructions to the SD card at a higher first frequency, And continue to execute for 10 seconds; otherwise, determine whether the SD card is in place by sending instructions to the SD card at a lower second frequency. Through this method, the purpose of replacing the SD card when the mobile terminal is turned on can be realized without affecting the prior art, and at the same time, the metal shrapnel used for SD card detection on the card holder in the prior art can be removed, so as to reduce the volume of the card holder. Purpose.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a mobile terminal, a method for controlling the detection frequency of an SD card thereof, and a storage medium. Background technique [0002] In the prior art, it has already been possible to detect the insertion of the SD card when the mobile terminal is turned on, so that the user can avoid the trouble of shutting down the mobile terminal every time the SD card is changed. [0003] In the prior art, the following scheme is used for the SD card insertion detection under the power-on state of the mobile terminal: an additional GPIO pin needs to be added on the SD card holder to realize the interruption detection of the SD card insertion; In addition to the pins of the card itself, a pin is required for interrupt detection of SD card insertion. [0004] Such as figure 1 As shown, it is a schematic diagram of the most commonly used SD card inserted into the deck in the pr...
