Problems solved by technology

[0003] In the process of implementing the present invention, the inventors of the present invention found that: in the related art, when the power supply of the host is insufficient to meet the required voltage of the storage device, the storage device will be reset, and with the increase of the service life of the host , the equipment will be aging, and the host will be prone to continuous insufficient power supply. However, the current demand voltage of the storage device is fixed. In this case, the storage device will be continuously reset and unable to work. cause damage

Embodiment 1

[0040] see image 3 , image 3 It is a schematic flowchart of a method for controlling a storage device provided by one embodiment of the present invention, the method is applied to the storage device described above, and the method for controlling the storage device includes:

[0041] 210. When the storage device is reset, determine whether the storage device satisfies the abnormal power-on condition, and if so, perform step 220, and if not, perform step 240.

[0042] The above-mentioned "resetting of the storage device" may include power-on reset, RES reset and low-voltage reset, etc., wherein, the power-on reset and RES reset are artificial normal power-on resets, which are realized through an externally connected reset circuit; The automatic reset can be realized by connecting the voltage detection chip to the RES pin of the storage device.

[0043] It should be noted that: when the storage device is reset, it means that the storage device is powered on again, but the st...

Embodiment 2

[0057] see Figure 4 , Figure 4 A schematic flowchart of a method for controlling a storage device provided in another embodiment of the present invention, the method for controlling a storage device includes:

[0058] 310. When the storage device is reset, determine whether the latest consecutive abnormal power-on times of the storage device is greater than or equal to a preset threshold, where the preset threshold is a natural number greater than zero.

[0059] 320. If the number of recent continuous abnormal power-on times is greater than or equal to a preset threshold, determine whether the current power consumption level of the storage device is the lowest level;

[0060] 330. If it is not the lowest level, reduce the power consumption level of the storage device, and make the storage device perform a power-on operation at the reduced power consumption level;

[0061] 340. If it is the lowest level, output an alarm signal.

[0062] When the power consumption level of ...

Embodiment 3

[0067] see Figure 5 , Figure 5 A schematic flowchart of a method for controlling a storage device provided in another embodiment of the present invention, the method for controlling a storage device includes:

[0068] 410: Start resetting the storage device;

[0069] 420: Determine whether the power-on state of the storage device is power-on or power-on completed, if it is power-on, execute step 430, and if it is power-on complete, execute step 460;

[0070]430: Increase the number of recent continuous abnormal power-on times by a preset value;

[0071] 440: Determine whether the latest consecutive abnormal power-on times of the storage device are greater than or equal to a preset threshold; if yes, perform step 450; if not, perform step 460;

[0072] 450: reduce the power consumption level of the storage device;

[0073] 460: before the storage device performs the power-on operation, mark the power-on state of the storage device as being powered on; After step 420, bef...

Abstract

The embodiments of the present invention relate to the technical field of storage devices, and disclose a method, device and electronic device for controlling storage devices. Wherein, the method includes: when the storage device is reset, determining whether the storage device satisfies the abnormal power-on condition; if so, reducing the power consumption level of the storage device; Perform a power-on operation according to the power consumption level; if not, make the storage device perform a power-on operation according to a preset power consumption condition. Through the above method, the embodiment of the present invention can effectively avoid the situation that the storage device is continuously reset due to insufficient power supply, which affects the normal use of the storage device.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of storage devices, and in particular, to a method, device, and electronic device for controlling a storage device. Background technique [0002] Storage devices include U disk (USB flash disk, USB flash disk), SSD, emmc, EMCP, ufs, SD card and other devices, which are widely used in various products, such as computers, mobile phones and other electronic products. As the functions of electronic products become more and more abundant, the capacity of storage devices is getting bigger and bigger, and the power consumption of devices is getting higher and higher. However, storage devices usually do not have their own power supply, but are powered by the host connected to it. [0003] In the process of implementing the present invention, the inventors of the present invention found that: in the related art, when the power supply of the host is insufficient to meet the required voltage of th...
