Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart illustrating an exception handling method according to an embodiment of the present invention. The method is applicable to the situation of overtime protection in abnormal situations, and can be executed by an exception handling device which can be composed of hardware and/or software and can be generally integrated in an intelligent rearview mirror and all intelligent terminals containing overtime protection functions. The method specifically comprises the following steps:
and S110, when the system is detected to jump from the normal mode to the abnormal mode, timing is started according to the time length matched with the abnormal mode.
Optionally, the normal mode may be a user-oriented system mode, and the abnormal mode may be a non-user-oriented system mode. For example, when a system performs a specific operation or a user malfunctions, the system may be automatically transitioned from the normal mode to the abnormal mode, for example, when the user erroneously selects a system debugging function, or when the system is upgraded, the system may be transitioned from the normal mode to the abnormal mode.
Optionally, the abnormal mode may include multiple modes, and a protection duration matched with each abnormal mode may be set in advance for each abnormal mode, where the protection duration may be determined according to actual needs of the abnormal mode, and the protection duration set corresponding to each abnormal mode may be different.
Because the abnormal mode usually has no automatic sleep mechanism, that is, the screen can be kept normally bright and the system CPU can continuously work in the abnormal mode, and in this case, if no human operation is performed, a large amount of electricity is consumed, therefore, when the system enters the abnormal mode, the timing is started according to the time length matched with the abnormal mode, so as to control the operation time of the system in the abnormal mode, and avoid unnecessary waste of electricity, and particularly, in the case of supplying power by using a storage battery, the electricity in the storage battery is prevented from being consumed and affecting the normal start of the system.
Preferably, the exception mode includes a recovery mode and a debug mode.
The Recovery mode may be a mode used for system upgrade and/or factory reset in the system, for example, a Recovery mode; the debug mode can be a debug mode used in a system to fix a system bug and/or a system development, such as a Fastboot mode. Of course, the abnormal mode may include other abnormal modes, and is not limited herein.
Preferably, the starting of the timing according to the duration matched with the abnormal pattern includes:
if the abnormal mode is the recovery mode, timing is started according to a first time length matched with the recovery mode;
if the abnormal mode is the debugging mode, timing is started according to a second time length matched with the debugging mode;
wherein the first duration is greater than the second duration.
For example, if the abnormal mode entered by the system is the recovery mode, indicating that the system is upgrading or recovering the factory settings, correspondingly, a time length longer than the time length required for normal upgrading or recovering the factory settings, that is, a first time length, may be set as the protection time length, and the timing is started according to the first time length as the highest time limit; if the abnormal mode entered by the system is a debugging mode, it indicates that bug repair is required to be performed when the system runs, or a debugging function is selected because of false triggering of a user or a developer needs to debug the system, correspondingly, a time length longer than that required for normal bug repair can be set, that is, a second time length is used as a protection time length, and timing is started according to the second time length as a highest time limit. Since the time duration required for system upgrade is greater than the time duration required for bug fix in most cases, the first time duration may be set to be greater than the second time duration.
Preferably, after the timing is started according to the duration matched with the abnormal pattern, the method further includes:
and if the user input operation is detected, restarting timing according to the time length matched with the abnormal mode.
For example, in order to avoid that the system mistakenly starts the timeout protection mechanism due to the fact that the system enters the abnormal mode through manual operation, for example, the user mistakenly operates or the developer debugging system jumps to the debugging mode, when the user input operation is detected in the abnormal mode, that is, the fact that a person is operating the system at the moment is explained, the timing can be restarted according to the time length matched with the abnormal mode, and the system can delay the timing starting time.
And S120, when the timing duration reaches the duration, controlling the system to shut down.
Optionally, timing may be performed in a countdown manner, that is, timing is started from the time of the highest time duration until the timing is zero, and it is determined that the timing time duration reaches the time duration matched with the current abnormal mode; and timing in a time-keeping timing mode, namely starting timing from zero until the timing time length is the same as the time length matched with the current abnormal mode, and determining that the timing time length reaches the time length. Illustratively, when the timing duration is determined to reach the duration, a shutdown instruction is called, and the system is controlled to be shut down according to the shutdown instruction.
When the timing duration reaches the duration, the control system is turned off, so that the overtime protection mechanism can be started in time when the system enters the abnormal mode, and the system is controlled to be turned off in time when the timing duration reaches the specified duration, the problem that the system consumes power continuously when the system has abnormal problems and a user does not use the system in a short time is avoided, and particularly in the vehicle-mounted intelligent rearview mirror, the extreme condition that the vehicle cannot be started due to the fact that the rearview mirror enters the abnormal mode and consumes the electric quantity of the vehicle-mounted storage battery can be avoided.
According to the technical scheme, the matched timing duration is set for the abnormal mode, timing is started when the abnormal mode is entered, the system is controlled to be shut down in time when the duration is reached, the advantages that different overtime protection mechanisms are set for different abnormal modes are utilized, the problem of power consumption of the system caused by the fact that the system is abnormal and a user does not use the system in a short time in the prior art is solved, the extreme condition of the electric quantity of the photovoltaic cell is avoided, and unnecessary electric energy waste is reduced.
Example two
Fig. 2 is a flowchart illustrating an exception handling method according to a second embodiment of the present invention. The present embodiment is optimized based on the above embodiments, and provides a preferred exception handling method, specifically, before starting timing according to a duration matched with an exception pattern, the optimization further includes: an exception handling operation performed by the system in the exception mode is detected and it is determined that the exception handling operation does not belong to a predefined legitimate operation. The method comprises the following specific steps:
s210, when the system is detected to jump from the normal mode to the abnormal mode, detecting the abnormal processing operation executed by the system in the abnormal mode.
Optionally, after the system enters the abnormal mode and before the system starts timing, the cause of the system jumping to the abnormal mode may be roughly determined by detecting the abnormal processing operation executed by the system in the abnormal mode. The exception handling operation may be an operation that the system needs to run in an exception mode, which causes the system to jump from a normal mode to an exception mode, for example, a system upgrade operation, a bug fix operation, a system debug operation, and the like. Alternatively, the exception handling operation may be triggered manually or automatically by the system, and is not limited herein. The purpose of detecting the exception handling operation executed by the system in the exception mode is to acquire the running condition of the system in the exception mode so as to judge whether the system belongs to normal jump.
S220, determining whether the abnormal processing operation belongs to a preset legal operation, if so, executing S250; if not, go to S230.
Optionally, the predefined legal operation may be, for example, a system upgrade operation, a bug fix operation, an operation of restoring factory settings, or the like, and the normal mode jump automatically occurs when the system is normally running. In contrast, the exception handling operation that is not a legal operation may be, for example, a system debugging operation, a system error reporting operation, or a mode jump that occurs when a manual operation or a system runs abnormally. If the abnormal processing operation belongs to legal operation, the mode jump is caused by normal operation of the system at the moment, and the mode jump can automatically return to the normal mode when the operation is finished; if the abnormal processing operation does not belong to legal operation, the mode jump is caused by manual operation or system abnormal operation, the mode jump can be returned to the normal mode only by the manual operation, and an overtime protection mechanism can be added to start timing shutdown.
The advantage of determining whether the abnormal processing operation belongs to the predefined legal operation is that different processing can be performed according to the actual jump situation, so as to avoid the problem of error shutdown when the system is executing normal operation due to the added overtime protection mechanism.
And S230, timing is started according to the time length matched with the abnormal pattern.
And S240, when the timing duration reaches the duration, controlling the system to shut down.
S250, detecting whether the system is abnormal or not in the process of abnormal processing operation, and if so, executing S260; if not, go to step S280.
For example, if the exception handling operation belongs to a legal operation, it indicates that the mode jump at this time is caused by normal operation of the system (e.g., system upgrade, factory reset), and it is necessary to detect whether the system is operating normally in the exception handling operation process, that is, to detect whether the system is abnormal, so as to determine whether the system needs to perform timeout protection.
And S260, starting timing according to the set time length.
For example, if an abnormality occurs in the system during the process of the abnormality processing operation, in order to avoid wasting electric energy due to the system staying in the abnormal mode for a long time, the timeout protection needs to be started, that is, timing is started according to a set time length, the set time length may be preset, different abnormal modes may set the same set time length, or different set time lengths, which is not limited herein.
And S270, controlling the system to shut down when the timing duration reaches the set timing duration.
For example, the timing may be performed in a countdown manner, that is, the timing is started from the time with the highest set time duration until the timing is zero, and it is determined that the timing time duration reaches the set time duration; the timing can also be carried out in a time-keeping timing mode, namely, the timing is started from zero until the timing duration is the same as the set duration, and the timing duration is determined to reach the set duration.
When the timing duration reaches the set duration, the shutdown control system has the advantages that the overtime protection mechanism can be started in time when the abnormal processing operation fails, and the shutdown control system can be controlled in time when the timing duration reaches the set duration, so that the problem that the system continuously consumes power when the system fails to operate in the abnormal processing operation and a user does not operate the system in a short time is solved, and particularly in the vehicle-mounted intelligent rearview mirror, the condition that the electric quantity of a vehicle-mounted storage battery is consumed to cause the extreme condition that the vehicle cannot be started due to the fact that the rearview mirror fails to be upgraded or repaired after the rearview mirror enters the abnormal mode due to system upgrading or repair holes can be avoided.
And S280, jumping the system from the abnormal mode to the normal mode when the abnormal processing operation is finished.
For example, if it is detected that the system is not abnormal during the exception handling operation, that is, the exception handling operation can be completed normally, the system is automatically jumped from the exception mode to the normal mode when the exception handling operation is ended, for example, if the system is upgraded normally or bug repair is completed normally, the system is automatically jumped from the exception mode back to the normal mode without starting the timeout protection in the exception mode.
According to the technical scheme, the abnormal processing operation executed in the abnormal mode is detected, whether the abnormal processing operation belongs to the legal operation specified in advance is judged, whether the system is abnormal in the abnormal processing operation process is further detected when the abnormal processing operation is determined to be the legal operation, whether an overtime protection mechanism is started is further determined according to actual conditions, the overtime protection is not started when the system is in normal operation, the overtime protection is started in time when the system is in abnormal operation, the extreme condition of the electric quantity of the light-consuming battery is avoided, unnecessary electric energy waste is reduced, the timeliness and the reliability of the overtime protection of the system are improved, and user experience is improved.
