Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Based on the above problems, embodiments of the present application provide a method, an apparatus, a storage medium, and a terminal for writing SD card data, which can effectively improve the writing speed of the SD card. The following will describe in detail. The following description of the embodiments is not intended to limit the preferred embodiments.
Referring to fig. 1, fig. 1 is a flowchart of an SD card data writing method according to an embodiment of the present disclosure. The SD card data writing method can be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palm computers, portable media players (Portable Media Player, PMP) and fixed terminals such as desktop computers. The specific flow of the SD card data writing method can be as follows:
101. when the data writing to the SD card is detected, a time difference value between the current time and the historical time when the data is written to the SD card last time is obtained.
Specifically, an instruction to write data to the SD card is initiated by a user. The writing of the data into the SD card means that the data in the memory of the terminal is moved to the SD card connected with the terminal, and the terminal is connected with the SD card through the hard interface. The written data is system memory information, and may include symbols, characters, numbers, voice, images, video, etc. Specifically, the system memory information can be displayed on the terminal interface in a file mode. For example, the user may select any one of the files in the terminal repository and then perform an operation to move to the SD card on this file. Specifically, the current time may be obtained by recording the time when the data is written into the SD card. The history time when the data is written to the SD card is obtained may be the time after the last writing of the data to the SD card is completed. The time difference between the recorded two times is calculated. For example, the last time data was written to the SD card, the time after completion may be 11 hours 30 minutes 4 seconds. The time until the data is currently written to the SD card may be 11 hours 30 minutes 6 seconds, and the time difference between the two writing of the data to the SD card is 2 seconds.
In some embodiments, the step "when writing data to the SD card is detected" may further include the following flow:
and executing the first working state when the data written into the SD card is detected to be the primary writing.
Specifically, when a user triggers an instruction of writing data into the SD card for the first time, namely, when the user performs primary data writing into the SD card, the terminal performs data writing into the SD card according to the first working state, so that the data writing into the SD card is prevented from being stopped when the history time of writing data into the SD card is not detected. The first working state may be: acquiring a current memory residual space, determining a current memory residual space interval, and setting the data writing speed into the SD card as a first SD card writing speed if the current memory residual space interval is in a first memory residual space interval; if the current memory remaining space interval is in the second memory remaining space interval or the third memory remaining space interval, the data writing speed to the SD card may be set to be the second SD card writing speed.
The memory residual space interval can be divided by the relation between the memory residual space and the preset memory residual space. For example, the preset memory residual space may include a first memory residual space and a second memory residual space, where the first memory residual space may be larger than the second memory residual space.
For example, the partitioning rule may be: if the memory residual space is larger than the first memory residual space, the memory residual space is located in a first memory residual space interval; if the memory residual space is smaller than or equal to the first memory residual space and larger than or equal to the second memory residual space, the memory residual space is located in a second memory residual space interval; and if the memory residual space is smaller than the second memory residual space, the memory residual space is positioned in a third memory residual space interval.
In some embodiments, the step "when writing data to the SD card is detected" may further include the following flow:
detecting a current memory residual space interval in which a current residual memory space is located in the process of writing data into the SD card;
determining whether the current memory residual space interval is an original memory residual space interval or not, wherein the original memory residual space interval is a memory residual space interval when data is written into the SD card;
if not, setting the writing speed according to the current memory residual space interval.
Specifically, during the process of writing data into the SD card, the current memory residual space is changed continuously, and the memory residual space interval is changed. And detecting a memory residual space interval in which the current memory residual space is located. For example, the current memory residual space can be obtained in real time, the current memory residual space is compared with the first memory residual space and the second memory residual space, and the memory residual space interval where the current memory residual space is located is determined according to the comparison result.
Specifically, the current memory residual space interval is compared with the original memory residual space interval, wherein the original memory residual space interval is the memory residual space interval where the obtained memory space is located before writing data into the SD card. If the current memory residual space is inconsistent with the original memory residual space, setting the SD card writing speed according to the relation between the current memory residual space interval and the current working state. The writing speed of the SD card can be improved by acquiring the residual space of the memory in real time and setting the writing speed of the SD card according to the residual space interval.
In some embodiments, the step of determining whether the current memory remaining space interval is the original memory remaining space interval further includes the following steps:
judging whether the current memory residual space interval is the second memory residual space interval or not;
if yes, determining whether the working state is the second working state;
if yes, maintaining the current writing speed to write data into the SD card.
Specifically, the obtained current memory residual space is compared with the first memory residual space and the second memory residual space, and a comparison result is obtained.
The comparison result may be that the current memory residual space is smaller than or equal to the first memory residual space and larger than or equal to the second memory residual space, and then the current memory residual space is determined to be in the second memory residual space interval.
Further, the current working state is detected. The current working state can be a first working state, and at this time, the data is written into the SD card according to the set writing speed of the first working state. The current working state can be the second working state, and at this time, data is continuously written into the SD card according to the current writing speed. In the step, when the memory residual space is in the second memory residual space in the second working state, the data writing of the SD card can still be continued.
102. When the time difference value is smaller than a preset time difference value, setting the working state as a second working state, wherein the second working state is as follows: and setting the data writing speed according to the relation between the current memory residual space and the first memory residual space interval and the third memory residual space interval.
Specifically, according to the calculated time difference value, the time difference value is compared with a preset time difference value. The preset time difference value can be automatically set according to the memory size system. The working state can be switched more reasonably and effectively according to the setting of the preset time difference value, and the writing speed of the SD card is set.
For example, the time difference may be smaller than the preset time difference, and at this time, the operating state is set to the second operating state. The second working state may be: acquiring a current memory residual space, determining a current memory residual space interval, and setting the data writing speed into the SD card as a first SD card writing speed if the current memory residual space interval is in a first memory residual space interval; if the current memory remaining space interval is in the third memory remaining space interval, the data writing speed to the SD card can be set to be the second SD card writing speed.
In some embodiments, the step of setting the working state to the second working state may further include the following procedures:
acquiring the residual space of the current memory;
if the current memory residual space is in the second memory residual space interval, starting timing;
and when the counted time reaches a preset time interval, switching the second working state into the first working state.
Specifically, when in the second working state, the remaining space of the memory can be obtained in real time. If the obtained memory residual space is detected to be in the second memory residual space interval, the writing speed of the current data written into the SD card is not changed, and timing is started. Specifically, when the preset time interval is reached, the current remaining space interval of the memory is still in the second remaining space interval of the memory, and the second working state can be switched to the first working state. By switching the working state at preset time intervals, the time for writing data into the SD card can be effectively saved.
103. When the time difference value is greater than or equal to the preset time difference value, setting the working state as a first working state, wherein the first working state is as follows: and setting the data writing speed according to the relation between the current memory residual space and the first memory residual space interval, the second memory residual space interval and the third memory residual space interval.
Specifically, according to the calculated time difference value, the time difference value is compared with a preset time difference value.
For example, the time difference may be equal to or greater than a preset time difference, and at this time, the operating state is set to be the first operating state.
In some embodiments, the step of setting the operation state to the first operation state may include the following procedures:
acquiring the memory residual space;
if the memory residual space is in the first memory residual space interval, setting the writing speed as a first writing speed;
and if the memory residual space is in the second memory residual space interval, setting the writing speed as a second writing speed.
Specifically acquiring a current memory residual space, determining a current memory residual space interval, and if the current memory residual space interval is in a first memory residual space interval, setting the data writing speed into the SD card as a first SD card writing speed; if the current memory remaining space interval is in the second memory remaining space interval or the third memory remaining space interval, the data writing speed to the SD card may be set to be the second SD card writing speed. When the obtained memory residual space is any value, the writing speed of the SD card can be set to write data into the SD card by executing the first working state.
In this embodiment, when data is written into the SD card by detecting, a time difference between a current time and a last time when data is written into the SD card is obtained, and when the time difference is smaller than a preset time difference, the working state is set to be a second working state, where the second working state is: setting data writing speed according to the relation between the current memory residual space and the first memory residual space interval and the third memory residual space interval; when the time difference value is greater than or equal to the preset time difference value, setting the working state as a first working state, wherein the first working state is as follows: and setting the data writing speed according to the relation between the current memory residual space and the first memory residual space interval, the second memory residual space interval and the third memory residual space interval. According to the method and the device, the time difference of the writing speed of the SD card is obtained through two continuous settings, the writing speed of the SD card is dynamically allocated according to the size of the time difference, the writing time of the SD card can be effectively saved, and the efficiency of writing data into the SD card is improved.
Referring to fig. 2, fig. 2 is a flowchart of another method for writing SD card data according to an embodiment of the present disclosure. In this embodiment, a mobile phone may be described as an example of a terminal. The specific scene application of the SD card data writing method can be as follows:
201. The terminal receives a request to write data to the SD card.
In this embodiment, it is first determined that the SD card is placed in the terminal. The user can start the instruction for writing data into the SD card, and the terminal executes corresponding operation according to the instruction after receiving the instruction for writing data into the SD card triggered by the user.
For example, referring to fig. 3, fig. 3 is an operation interface diagram provided in an embodiment of the present application. The user opens the terminal, and opens the storage folder to see the terminal screen interface shown on the left side of fig. 3, where the interface is a file list interface, and each folder in the system storage space is shown. The user may select any file to open.
For example, the user opens folder, may select folder 1, and then the terminal screen interface jumps to the interface shown on the right side of FIG. 3. The interface may present the contents of file 1 and the user may operate folder 1 by triggering a button below the screen. Specifically, the user may click on the "move to SD card" button, triggering an instruction to write data to the SD card.
202. The terminal obtains the current memory residual space according to the request, sets the data writing speed according to the first working state and records the data writing time.
In this embodiment, the terminal may set the SD card writing speed according to the first working state according to the received SD card writing data request.
For example, the current memory remaining space M is obtained, and for example, the memory remaining space M may be 500M. The memory residual space M is combined with a first memory residual space (M1) and a second memory residual space (M2), wherein the first memory residual space M1 can be 400M, and the second memory residual space M2 can be 300M. At this time, if the memory residual space M is greater than the first memory residual space M1, it may be determined that the memory residual space interval in which the memory residual space M is located is the first memory residual space interval. In the first working state, when the memory is in the first memory residual space interval, the writing speed of the SD card can be set to be the first writing speed, wherein the first writing speed can be 10M/s.
203. The terminal starts a first timer, acquires the current memory residual space at fixed time, sets the data writing speed according to a first working state and records the data writing time.
In this embodiment, when the terminal sets the SD card writing speed and starts to perform the operation of writing data to the SD card at this writing speed, the first timer may be started. For example, the time setting of the first timer may be 5 seconds. And acquiring the current memory residual space according to the time set by the first timer, setting the writing speed of the SD card according to the first working state, and recording the writing time.
For example, the terminal may start writing data to the SD card at a writing speed of 10M/sec, and at the same time, the first timer may start setting a 5-second timer. The timer may count down for 5 seconds to 0 seconds, or count up for 0 seconds to 5 seconds. After the timing is finished, the remaining memory space M3 is acquired, for example, the remaining memory space M3 may be 600M. At this time, the memory residual space M3 may still be larger than the first memory residual space M1, and then it may be determined that the memory residual space interval where the memory residual space M3 is located is the first memory residual space interval. In the first working state, when the memory is in the first memory residual space interval, the writing speed of the SD card can be set to be the first writing speed, namely 10M/s. The time when the terminal records the current data writing to SD may then be 12 hours 30 minutes 4 seconds.
204. The terminal obtains the time difference between the adjacent two data writing moments, judges whether the time difference is smaller than a preset time difference, and if yes, executes step 205; if not, go to step 206.
In this embodiment, when the terminal writes data to the SD card, the writing speed may also be changed according to the continuous change of the remaining space of the memory. The current time is recorded each time the writing speed is set. And the terminal performs subtraction calculation on two adjacent moments to obtain a time difference value.
For example, the first time the terminal records the writing speed may be 12 hours 30 minutes 4 seconds, the second time the terminal records the writing speed may be 12 hours 30 minutes 6 seconds, and the terminal subtracts the two times to obtain a time difference of 2 seconds. And then comparing the obtained time difference value with a preset time difference value, wherein the preset time difference value can be 3 seconds. By comparison, it can be determined that the time difference is smaller than the preset time difference. Step 205 may be performed based on the comparison result.
In some embodiments, another situation may also exist. For example, the time when the terminal records the first set writing speed may be 12 hours and 30 minutes and 4 seconds, the time when the terminal records the second set writing speed may be 12 hours and 30 minutes and 8 seconds, and the terminal subtracts the two times to obtain a time difference of 4 seconds. And then comparing the obtained time difference value with a preset time difference value, wherein the preset time difference value can be 3 seconds. By comparison, it can be determined that the time difference is greater than the preset time difference. Step 206 may be performed based on the comparison result.
205. And the terminal switches the current first working state to the second working state and starts a second timer to acquire the current memory residual space.
In this embodiment, when it is determined that the time difference between the two adjacent SD card writing speed settings is smaller than the preset time difference, the terminal switches the first operating state executed at this time to the second operating state. The second timer is then started, for example, in order to avoid frequent writing of data to the SD card, the set duration of the second timer may be longer than the set duration of the first timer, and the second timer may be set to 20 seconds. And the terminal closes the first timer and acquires the remaining space of the memory according to the set duration of the second timer.
For example, at this time, the remaining memory space may be 100M, and the writing speed of the terminal for writing data into the SD card may be 10M/s. The terminal can switch the first working state to the second working state, when the terminal is in the second working state, the memory residual space is smaller than the second memory residual space M2, the memory residual space interval is determined to be a third memory residual space interval, and the second writing speed can be set to write data into the SD card. Wherein the second writing speed may be 5M/sec. And starting to count according to the duration of 20 seconds set by the second timer to acquire the memory residual space.
206. The terminal sets the writing speed according to the first working state.
In this embodiment, when it is determined that the time difference between the two adjacent SD card writing speed settings is greater than the preset time difference, the terminal will continue to execute the first working state.
For example, at this time, the remaining memory space may be 100M, and the writing speed of the terminal for writing data into the SD card may be 10M/s. The terminal can continue to execute the first working state, when the terminal is in the first working state, the memory residual space is smaller than the second memory residual space M2, the memory residual space interval is determined to be a third memory residual space interval, and the second writing speed, namely the speed of 5M/s, can be set for writing data into the SD card.
207. When the terminal is in the second working state and the data writing speed is not set in the second timer, the second working state is switched to the first working state, and the second timer is closed.
In this embodiment, when the terminal is in the second operating state, and the second timer is started. And in the set time length of the timer, the memory residual space of the terminal can be always in the second memory residual space interval, and the writing speed is not set for the SD card in the second timing period. At this time, the terminal switches the second operating state to the first operating state and closes the second timer.
