Example 2
An embodiment of the present invention provides a method for writing file system data in an intelligent terminal device, as shown in fig. 2, including:
step S201, determining whether the intelligent terminal equipment is monitored to be abnormal or not;
the method comprises the steps of monitoring the system running condition of the intelligent terminal equipment in real time, and determining that the intelligent terminal equipment is abnormal when the intelligent terminal equipment is halted according to the running parameters of the intelligent terminal equipment or when the associated operation of a forced shutdown instruction is monitored.
Step S202, determining that a crash occurs according to the operation parameters of the intelligent terminal equipment, and writing data into a disk when the data of a file system is cached in a current memory;
the method comprises the steps of adding a control function for synchronizing the file system, namely writing data in the memory into a disk, to a control function triggered when the intelligent terminal device is halted in advance, and generating a corresponding synchronous control instruction, so that the control instruction calls the corresponding control function to write the data in the memory into the disk when being triggered.
The control function called when the intelligent terminal device is halted can be a Die function or a sonic function. The Die function is a built-in function which can exit the current process, and the Panic function is a built-in function which can stop the program execution flow. When the system finds out the failure which can not continue to operate, the two functions are called, the current program is quitted through the Die function, the subsequent program is stopped to be executed through the Panic function, and the system displays the error number so as to carry out error monitoring and debugging in the following.
And when the crash is determined according to the operation parameters of the intelligent terminal equipment in the steps, determining that the intelligent terminal equipment is abnormal, calling the synchronous control instruction at the moment, triggering a corresponding control function, and writing the data in the memory into a disk. The method solves the problem of abnormal file system caused by system crash of the intelligent terminal equipment, and can ensure the stability of the file system to the maximum extent when the system crashes.
Step S203, when the correlation operation of the forced shutdown instruction is monitored and it is determined that the data of the file system is cached in the current memory, writing the data into the disk.
According to the operation duration required by the association operation of the forced shutdown instruction of the intelligent terminal device, namely the forced shutdown operation duration, determining a first preset duration and a second preset duration, wherein the second preset duration is longer than the first preset duration, and the second preset duration does not exceed the operation duration. The first preset time is used for determining whether to start writing data into the disk, and the second preset time is used for determining whether to stop writing data into the disk.
And monitoring the operation associated with the control instruction of the intelligent terminal equipment, and determining that the intelligent terminal equipment is abnormal when the operation associated with the forced shutdown instruction is monitored. Determining that the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds a first preset duration according to a preset timer or according to the system time of the intelligent terminal device, starting to write data in a memory into a disk, and continuing to monitor the associated operation generating the forced shutdown instruction, and when determining that the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds the first preset duration and does not exceed a second preset duration, stopping writing the data into the disk, otherwise, not stopping.
If the determined second preset time length is less than the forced shutdown operation time length, when the monitored continuous operation time length of the associated operation generating the forced shutdown instruction exceeds the forced shutdown operation time length, generating the forced shutdown instruction to trigger shutdown operation.
If the determined second preset time length is less than the forced shutdown operation time length, when the monitored continuous operation time length of the associated operation generating the forced shutdown instruction exceeds the second preset time length, generating the forced shutdown instruction to trigger shutdown operation. The method can greatly reduce the probability of file system abnormity caused by abnormal power failure of the intelligent terminal equipment triggered by forced shutdown, and enhances the stability of the file system.
Example 3
An embodiment of the present invention provides a method for writing file system data in an intelligent terminal device, as shown in fig. 3, including:
step S301, determining whether the intelligent terminal device reaches the preset timing synchronization time or not;
the Laptop mode is a power saving mode, and power consumption balance can be achieved by adjusting all power management characteristics of the intelligent terminal device. The Laptop mode may cause write operations to be in burst form, thereby allowing some power saving mechanisms to better intervene.
When the file system of the intelligent terminal equipment is synchronized at regular time, the shorter the preset timing synchronization time is, the more frequent the operation of writing data into a disk from a memory is, and the better the stability of the file system is. However, frequent execution of the operation of writing data from the memory to the disk causes an increase in power consumption and a rapid power consumption, so that a suitable timing synchronization time can be set in a Laptop mode, so that a relatively small power consumption is ensured, a small timing synchronization time is obtained, the stability of the file system and the balance of the power consumption of the system are realized, and the stability of the file system is improved to the greatest extent.
The method for presetting the timing synchronization time comprises the following steps:
when the intelligent terminal device does not start the Laptop mode currently, a timing period is determined according to an indication parameter of a user, preset timing synchronization time is determined according to the timing period, and data in the memory are written into a disk at intervals of the timing synchronization time periodically.
When the intelligent terminal device is currently in a Laptop mode, determining a proper timing period according to the requirements on the power consumption of the intelligent terminal device and the stability of a file system, determining preset timing synchronization time according to the timing period, and periodically writing data in the memory into a disk at intervals of the timing synchronization time. The timing synchronization time can be determined by setting different timing synchronization times through multiple attempts in advance to perform testing, and selecting the timing synchronization time with the best balance effect on stability and power consumption as the timing synchronization time of the intelligent terminal equipment.
And monitoring the system time of the intelligent terminal equipment in real time, and executing the step S302 when the timing synchronization time preset by the method is determined to be reached.
Step S302, when the situation that the intelligent terminal device reaches the preset timing synchronization time is monitored and the situation that the data of the file system is cached in the current memory is determined, the data are written into a magnetic disk.
And when the intelligent terminal device reaches the preset timing synchronization time, writing the data in the memory into the disk. The method performs full-disk file system synchronization at regular time regardless of whether the disk is active or not, writes data in the memory into the disk, and can set proper timing synchronization time by combining with the Laptop mode, thereby realizing the balance of file system stability and equipment power consumption.
In the embodiment of the present application, a specific method for writing data in a memory into a disk may adopt the prior art, and details are not described here.

the existing smart phones are powered by built-in batteries, and the smart phones cannot be restarted by plugging and unplugging the batteries when the smart phones are halted, so that a function of pressing a power key for a certain time to trigger a power management chip to close power output is added, and forced shutdown is realized.
In this embodiment, the time length of the forced shutdown operation is set to 10s, that is, the power key 10s is pressed for a long time to forcibly shut down the computer. And determining a first preset time length and a second preset time length according to the forced shutdown operation time length. Here, the first preset time period is determined to be 6s and the second preset time period is determined to be 9.5 s.
When the associated operation that a forced shutdown instruction is generated, namely a power key is pressed, is monitored, a first timer is set and started to time, and the timing duration of the first timer is set to be a first preset duration 6 s.
Step S402, determining whether the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds a first preset duration, if so, executing step S403, otherwise, executing step S406;
if the power key is in the pressed state until the first timer finishes timing, which indicates that the power key is pressed for 6S, it is determined that the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds the first preset duration 6S, and step S403 is executed.
If the key state of the power key is changed from being pressed to being released in the timing process of the first timer, which indicates that the operation of pressing the power key for a long time is stopped, it is determined that the duration of the continuous operation of the associated operation generating the forced shutdown instruction does not exceed the first preset duration 6S, and step S406 is executed.
Step S403, writing the data in the memory into a disk, and setting and starting a second timer;
and when the continuous operation time length of the associated operation generating the forced shutdown instruction is determined to exceed the first preset time length, starting to write the data in the memory into the disk, and simultaneously setting and starting a second timer to time, wherein the timing time length of the second timer is set to be the second preset time length 9.5s minus the first preset time length 6s, namely 3.5 s.
Step S404, determining whether the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds a second preset duration, if so, executing step S405, otherwise, executing step S406;
if the power key is in the pressed state until the second timer finishes timing, which indicates that the power key is pressed for 9.5S, it is determined that the duration of the continuous operation of the associated operation generating the forced shutdown instruction exceeds the second preset duration of 9.5S, and step S405 is executed.
If the key state of the power key is changed from being pressed to being released in the timing process of the second timer, which indicates that the operation of pressing the power key for a long time is stopped, it is determined that the duration of the continuous operation of the associated operation generating the forced shutdown instruction does not exceed the first preset duration 6S, and step S406 is executed.
In step S405, a shutdown operation is triggered after a forced shutdown instruction is generated.
And when the continuous operation time of the associated operation generating the forced shutdown instruction is determined to exceed the second preset time 9.5s, continuing to synchronize the file system, responding to the forced shutdown instruction when the forced shutdown operation time is reached, and closing the smart phone.
Step S406, the current flow is stopped.
