Fig. 2 is a flowchart of a power-down restart identification method according to a first embodiment of the present application. The specific flow shown in fig. 2 will be described in detail.

Step S101, a CPU time stamp is acquired.

In this embodiment, since the CPU time stamp is cleared only when the power-down event occurs, and the CPU time stamp is kept normally clocked in the case of non-power-down restart such as hot reset, the power-down event can be identified by determining whether the CPU time stamp has been cleared or not, and then by the size of the CPU time stamp.

Step S102, judging whether the storage unit stores a restart file.

In this embodiment, preferably, the storage unit is a hard disk.

The restart file refers to a log file generated by the device at the time of restarting. For example, when a restart event occurs in the device on the fly, a restart flag is generated before a hot reset or other restart software tool performs a restart, that is, the restart file is generated.

Step S103, if not, judging whether the CPU time stamp is larger than the preset starting time.

When the storage unit does not store the restart file, that is, when the storage unit does not store the restart file, comparing the time of the CPU time stamp with the preset starting time, and judging whether the CPU time stamp is larger than the preset starting time.

The preset starting time refers to time for normal starting of the equipment. For example, the device may be a computer, a mobile phone, or a server. Here, the present application is not particularly limited.

In this embodiment, the preset start-up time may be different according to the device tested by the user during actual use, and the normal start-up time of the device may be different. Therefore, the selection of the preset starting time may be selected according to specific practical situations, which is not limited herein.

In this embodiment, when the restart file is stored in the storage unit, the restart file is moved to the storage backup unit. Preferably, after the restart file is moved to the storage backup unit, the restart file stored in the storage unit is deleted. The data storage of the storage unit is reduced, and adverse effects on the restarting reason due to the fact that the restarting file is still reserved in the storage unit after the next restarting are avoided.

In this embodiment, the moving the restart file to the storage backup unit refers to obtaining a restart reason corresponding to the restart file; and moving the restart reason to a storage backup unit.

In this embodiment, the storage backup unit and the storage unit may not be the same storage device, but may also be the same storage device. Preferably, the storage backup unit is not the same storage device as the storage unit. The storage backup unit is a hard disk.

Step S104, if the CPU time stamp is smaller than or equal to the preset starting time, the restarting reason is determined to be the power-down restarting.

In this embodiment, since the CPU time stamp is cleared only when an external power-down event occurs, the CPU time stamp keeps normal timing in a non-power-down restart situation such as a hot reset. Therefore, there may be a change in the length of time recorded by the CPU time stamp. When the CPU time stamp is smaller than or equal to the preset starting time, the current restarting reason can be obtained to be the power-down restarting. Such as an external power down event caused by a human power down, a cold reset, a switch failure, or a power failure.

Fig. 3 is a flowchart of a power-down restart identification method according to a second embodiment of the present application. The specific flow shown in fig. 3 will be described in detail.

Step S201, a CPU time stamp is acquired.

Step S202, judging whether the storage unit stores a restart file.

Step S203, if not, judging whether the CPU time stamp is larger than the preset starting time.

Step S204, if the CPU time stamp is smaller than or equal to the preset starting time, the restart reason is determined to be power-down restart.

The specific implementation manners of step S201, step S202, step S203 and step S204 refer to the corresponding steps in the first embodiment, and are not described herein again.

In step S205, if the CPU time stamp is greater than the preset start time, it is determined that the restart cause is a restart caused by an unknown fault.
