The core of the invention is to provide a state control method and related components of the storage device, which can be forced to be shut down only after a forced shutdown instruction is received and the preset shutdown verification information is successfully verified, thereby ensuring the normal work of the storage device and the storage of cache data.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of a method for controlling a state of a storage device according to the present invention, and fig. 2 is a schematic structural diagram of a state control apparatus of a storage device according to the present invention. The method comprises the following steps:
s11: when the storage device 23 is in a power-on state, judging whether a forced power-off instruction sent by the level conversion chip 22 is received;
s12: if a forced shutdown instruction is received, judging whether preset shutdown verification information is received or not;
the applicant considers that the processor 52 in the prior art immediately controls the storage device 23 to shut down when receiving the forced shutdown instruction, but the forced shutdown button 21 may be pressed not only at the subjective intention of the user, but also may be pressed by mistake due to the complexity of the power line, if the storage device 23 is forced to shut down because the forced shutdown button 21 is pressed by mistake, data in the storage device 23 may be lost, even though the storage device 23 capable of storing data in the hard disk during forced shutdown exists in the prior art, the shutdown time and the startup time of the storage device 23 are both long, and when the storage device 23 is shut down without the subjective intention of the user, the storage service may be interrupted, which brings a bad experience to the user.
In order to solve the above technical problem, in the present application, it is also determined whether a forced shutdown instruction is received when the storage device 23 is in a power-on state, but after the forced shutdown instruction is received, it is determined whether preset shutdown verification information is received first instead of directly controlling the storage device 23 to shutdown.
The preset shutdown verification information may be face information, fingerprint information, or number or character information input by a user on a keyboard, which is not limited in this application.
It should be noted that, in the present application, the forced shutdown instruction is sent by the level shift chip 22 based on the state of the forced shutdown button 21, for example, when the time for which the forced shutdown button 21 is pressed is not less than the preset shutdown time, the level shift chip 22 sends the forced shutdown instruction, but a specific sending manner of the forced shutdown instruction is not limited in the present application.
S13: if the preset shutdown verification information is received, controlling the storage device 23 to shut down;
when a forced shutdown instruction is received and preset shutdown verification information is received, it may be determined that this forced shutdown is not the forced shutdown button 21 is touched by mistake, but the user desires to forcibly shutdown the storage device 23, and at this time, the storage device 23 may be shutdown in order to meet the user's requirement.
S14: and if the preset shutdown verification information is not received, controlling the storage device 23 to continue to operate.
When a forced shutdown instruction is received, but the preset shutdown verification information is not received, or the received information is not the preset shutdown verification information, it may be determined that the forced shutdown may be that the forced shutdown button 21 is touched by mistake, or that the forced shutdown button 21 is pressed illegally, at this time, the storage device 23 is not controlled to be forced to be shut down, but the storage device 23 is controlled to continue to operate, so that data loss is avoided.
In conclusion, this application is not indirect judgement to the temperature through the electric current of mainboard, but directly detects the temperature to remind the user when the mainboard temperature is high, improved the accuracy of judging the temperature, and further guaranteed the normal work of mainboard.
On the basis of the above-described embodiment:
as a preferred embodiment, before determining whether a forced shutdown instruction sent by the level shift chip 22 is received, the method further includes:
judging whether a starting-up instruction is received or not;
if a startup instruction is received, judging whether the storage device 23 is in a startup state;
if the power-on state is detected, controlling the storage device 23 to continue to operate, and entering a step of judging whether a forced power-off instruction sent by the level conversion chip 22 is received;
if not, controlling the storage device 23 to start up, and entering a step of determining whether a forced shutdown instruction sent by the level conversion chip 22 is received.
In this embodiment, after receiving the power-on command, it is first determined whether the storage device 23 is currently in the power-on state, and if not, the storage device 23 may be controlled to power on, so as to determine whether a forced power-off command is received; while the memory device 23 is in the power-on state, the memory device 23 may remain operational.
As a preferred embodiment, before determining whether a forced shutdown instruction sent by the level shift chip 22 is received, the method further includes:
when the storage device 23 is in a power-on state, judging whether a forced power-off interruption instruction sent by the level conversion chip 22 is received;
if a forced shutdown interrupt instruction is received, controlling the storage device 23 to perform shutdown interrupt, and entering a step of determining whether the forced shutdown instruction sent by the level conversion chip 22 is received.
In this embodiment, in the prior art, when the storage device 23 is in a power-on state, if a power-on instruction is received at this time, a user may press the forced power-off button 21 to forcibly power off the storage device 23, so as to avoid that the storage device 23 is mistakenly powered off because the pressing of the forced power-off button 21 is not a subjective intention of the user, the level shift chip 22 in this application sends a forced power-off interrupt instruction at this time, so as to avoid that the storage device 23 is controlled to be immediately powered off after the forced power-off instruction is subsequently received.
In a preferred embodiment, the level shift chip 22 is configured to output a power-on command when the forced power-off button 21 is pressed for a time not less than a preset power-on time but less than a preset interrupt time; outputting a forced shutdown interrupt instruction when the forced shutdown button 21 is pressed for a time not less than the interrupt preset time but less than the shutdown preset time; the forced shutdown instruction is output when the forced shutdown button 21 is pressed for a time not less than a shutdown preset time.
The level shift chip 22 in this embodiment can output different instructions according to the time when the forced shutdown button 21 is pressed, specifically, when the forced shutdown button 21 is pressed, and the time when the forced shutdown button 21 is pressed is not less than the preset startup time, but is less than the preset interruption time, it can only be determined that the user currently controls the storage device 23 to be powered on, and therefore, the motor shift chip outputs a startup instruction to the processor 52; when the time for which the forced shutdown button 21 is pressed is not less than the interruption preset time but less than the shutdown preset time, it can be determined that the user may want to control the storage device 23 to be forcibly shutdown, and in order to avoid the storage device 23 being shutdown, the level shift chip 22 outputs a forced shutdown interruption instruction to control the storage device 23 to be shutdown and interrupted; when the time for which the forced shutdown button 21 is pressed is not less than the preset shutdown time, it may be determined that the user wants to control the storage device 23 to be forcibly shutdown, at this time, the processor 52 verifies whether the preset shutdown verification information is received, and only if the verification is successful, the storage device 23 is controlled to be shutdown.
It should be noted that, in the present application, the level shift chip 22 is disposed between the forced shutdown button 21 and the processor 52, and a first output terminal of the level shift chip 22 is connected to a first input terminal of the processor 52, and a second output terminal is connected to a second output terminal of the processor 52. When the forced shutdown button 21 is pressed, the forced shutdown button 21 may be considered to input the low level to level conversion chip 22, and when the forced shutdown button 21 is released, the forced shutdown button 21 may be considered to input the high level to level conversion module. When the time for receiving the low level is not less than the preset startup time but less than the preset interrupt time, the level shift chip 22 outputs the low level from the first output terminal and outputs the high level from the second output terminal to output a startup instruction to the processor 52; when the time for receiving the low level is not less than the preset interrupt time but less than the preset shutdown time, the level shift chip 22 outputs the high level from the first output terminal and outputs the high level from the second output terminal to output a forced shutdown interrupt instruction to the processor 52; when the time for receiving the low level is not less than the preset shutdown time, the level shift chip 22 outputs the high level from the first output terminal, and outputs the low level from the second output terminal, so as to output a forced shutdown instruction to the processor 52. Referring to fig. 3, fig. 3 is a schematic diagram of an output instruction of a level shift chip according to the present invention.
It should be noted that, in order to ensure that the storage device 23 is not forced to be powered off, the processor 52 may not recognize the forced power-off instruction directly, and only when the storage device 23 is powered off, the storage device 23 may be powered off.
The preset time for starting up may be, but is not limited to, 20ms, the preset time for interrupting may be, but is not limited to, 2.02S, and the preset time for shutting down may be, but is not limited to, 3.02S.
