Problems solved by technology

There is a problem here. At this time, if the SD card is inserted or pulled out, the mobile terminal vibrates, or falls, the SD card will be displaced in the card slot, and other pins in the SD card may touch the SD card. Power supply pins burn out SD card

Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] see figure 1 , figure 1 It is a flow chart of a preferred embodiment of the control method for preventing card burning when the mobile terminal is turned on in the present invention.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides a control method for preventing card burning when the mobile terminal is turned on, including the following steps:

[0040] In step S100, the mobile terminal is powered on to detect the power-on state.

[0041] When starting up, the power supply voltage of the SD card must be supplied for a period of time (usually...

Abstract

The invention relates to the technical field of mobile terminals and discloses a control method and system for preventing a mobile terminal from burning the card when in starting up. The method comprises the following steps: a storage bit used for marking starting-up reasons is arranged in a brown-out not-easy-to-loss memorizer of the mobile terminal in advance; the mobile terminal is turned on to detect the starting-up state; when the mobile terminal detects that the starting-up state is halted, the supply voltage of an SD card is started to be in a normally-supply mode so as to prevent the SD card from being burnt out; and when the mobile terminal detects that the starting-up state is normal, the supply voltage of the SD card is started to be in a normal mode. The invention has the advantage that when the mobile terminal detects that the starting-up state is halted, the supply voltage of the SD card is started to be in a normally-supply mode so as to prevent the SD card from moving in a card slot when the SD card is inserted or pulled, the mobile terminal vibrates, drops or the like during starting up, and the problem that the SD card is burnt out because other pins of the SD card touch the power supply pin of the SD card can be avoided.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a control method and system for preventing card burning when a mobile terminal is turned on. Background technique [0002] In the process of using the mobile terminal, there will inevitably be abnormal situations such as crashes. In order to effectively analyze the cause of the crash, the mobile terminal manufacturer has added an on-site storage mechanism to the mobile terminal. Restart the operation, and then save the relevant data information of the crash in the previous memory to the SD card (because at present, large-capacity memory is generally used, often with several G, so often only the information in the memory can be saved to the SD card) . [0003] Due to the large storage capacity, it generally takes half a minute to save all the contents of the internal memory to the SD card. During this process, the SD card requires constant power supply. There is...
