The technical solution of the embodiments of the present invention is specifically described below with reference to the accompanying drawings.

The intelligent terminal in the embodiment of the invention can comprise a terminal with an operating system, such as a smart phone, a tablet computer or an electronic reader.

The embodiment of the invention provides a low-power self-protection method of an intelligent terminal, wherein the flow schematic diagram of the method is shown in figure 1, and the method comprises the following steps:

step S101: and determining that the battery of the intelligent terminal in the charging state is continuously in the low-power state.

Specifically, the intelligent terminal determines that the intelligent terminal is continuously in a charging state. The specific method for determining that the intelligent terminal is in the charging state is well known to those skilled in the art, and is not described herein again.

Determining that the battery of the intelligent terminal is continuously in the low-power state comprises: and determining that the battery voltage of the intelligent terminal is continuously lower than a preset threshold value, and entering a low-power state.

Preferably, various methods can be used to determine that the battery of the intelligent terminal is continuously in the low power state.

A method for determining that a battery of a smart terminal is continuously in a low-power state comprises the following steps: and determining that the battery of the intelligent terminal is continuously in a low-power state after recognizing that the system has low-voltage interruption of the battery for many times. The method will be described in detail later, and will not be described herein.

Another method for determining that a battery of a smart terminal is continuously in a low-power state includes: and determining that the battery of the intelligent terminal is continuously in a low-power state after detecting that the battery voltage of the system is lower than a preset threshold value for multiple times. The method will be described in detail later, and will not be described herein.

Preferably, before the intelligent terminal is determined to be continuously in the charging state or the battery of the intelligent terminal is determined to be continuously in the low-power state, whether the input voltage of the battery of the intelligent terminal is zero is confirmed; if so, continuously determining whether the intelligent terminal is continuously in a charging state and whether a battery of the intelligent terminal is continuously in a low-power state; if not, the flow is ended.

Step S102: and triggering a shutdown instruction in a low power state.

When the intelligent terminal is determined to be continuously in the charging state and the battery of the intelligent terminal is determined to be continuously in the low-power state in the steps, in the step, a shutdown instruction is triggered.

The shutdown instruction may be a custom program having a human-computer interaction function to prompt a user to perform a line change operation, or may be implemented by calling a system interface, and specifically, the triggered shutdown instruction is an automatic shutdown instruction preset by the system.

Step S103: and executing the shutdown instruction to enable the intelligent terminal to realize shutdown.

Specifically, a preset shutdown instruction is reported to the application, and the application actively executes shutdown for the intelligent terminal according to the shutdown instruction.

Preferably, in the process of executing the shutdown instruction, a prompt window containing prompt information is popped up by the process of the self-defined application layer program receiving the shutdown instruction, and shutdown is executed after receiving the first user instruction or a predetermined time elapses, or the shutdown process is exited after receiving the second user instruction. For example, a window is provided, wherein the window contains warning information, two keys of 'confirm' and 'cancel' are provided and are respectively used for triggering the first user instruction and the second user instruction, and when the user selects 'confirm', the first user instruction is triggered to execute shutdown; and when the user selects 'cancel', the shutdown process is exited.

Those skilled in the art can understand that the step of actively executing the shutdown instruction includes steps of properly processing data and programs, such as storing data in the operation of the intelligent terminal, normally exiting a program in operation, and the like, so that data abnormality can be prevented. In addition, the method comprises the step of normally powering off hardware circuits such as chips and devices in the intelligent terminal, and can prevent the hardware circuits from being damaged due to passive power off, thereby protecting the hardware circuits and prolonging the service life of the hardware circuits.

Referring to the above step S101, a flow chart of the method for recognizing that there is a low-voltage battery interrupt in the system for multiple times is shown in fig. 2, and includes the following steps:

s201: and receiving a battery low voltage interrupt triggering instruction of the system.

In the embodiment of the invention, the intelligent terminal presets a threshold value, which is called a preset threshold value for short, according to the minimum voltage value required by each of hardware circuits such as all chips, devices and the like in the intelligent terminal. The preset threshold is larger than the minimum voltage value required by hardware circuits such as all chips, devices and the like in the intelligent terminal.

A person skilled in the art can determine the minimum voltage value of each hardware circuit such as each chip, device, and the like in the intelligent terminal according to the historical power consumption data, the empirical data, or the methods or approaches such as experimental measurement of the intelligent terminal, and further determine the preset threshold.

The system circularly detects the voltage of the battery, and sends a battery low-voltage interruption triggering instruction after detecting that the current voltage of the battery is smaller than a preset threshold value.

And the intelligent terminal receives a battery low voltage interrupt trigger instruction of the system.

S202: after a delay of a predetermined duration, the interrupt status register of the system is read to confirm that a battery low voltage interrupt of the system exists.

Specifically, after the intelligent terminal is delayed for a preset time, reading an interrupt state register of the system, and if the interrupt state register reads the battery low-voltage interrupt, determining that the battery low-voltage interrupt of the system exists; if the battery low voltage interrupt is not read from the interrupt status register, it is determined that a battery low voltage interrupt of the system is not present.

S203: after at least one time of delay of preset time, determining whether the low-voltage interruption of the battery of the system exists; if so, confirming that the battery of the intelligent terminal is continuously in a low-power state; otherwise, the flow is ended.

Specifically, after the delay of the preset time length is at least once, the intelligent terminal can read the battery low-voltage interruption from the interruption state register of the system, and then the battery low-voltage interruption of the system is confirmed to exist continuously, so that the battery of the intelligent terminal is confirmed to be in the low-power state continuously.

Preferably, if the intelligent terminal does not read the battery low-voltage interruption from the interruption state register of the system after a delay of a preset time length is reached, it is determined that the battery low-voltage interruption of the system does not exist continuously, and further it is determined that the battery of the intelligent terminal is not in a low-power state continuously; ignoring previously read battery low voltage interrupts and received battery low voltage interrupt trigger instructions; ending the process or jumping to step S201 to continue executing the next process of determining that the battery of the intelligent terminal is continuously in the low power state.

It can be understood that even if the system is interfered and the like, the battery low-voltage interruption trigger instruction is sent by mistake and/or the battery low-voltage interruption is stored in the interruption state register by mistake, whether the battery of the intelligent terminal is really in the low-power state or not can be identified in the step, and the unexpected shutdown caused by the condition that the battery is not continuously in the low-power state can be prevented, so that the reliability of the follow-up active shutdown of the intelligent terminal is integrally ensured.

Referring to the above step S101, a schematic flow chart of the method for detecting that the battery voltage of the system is lower than the preset threshold value for multiple times is shown in fig. 3, and includes the following steps:

s301: circularly judging whether the battery voltage of the system is lower than a preset threshold value or not by taking the first time delay as an interval; if yes, go to step S302; otherwise, the step is continuously executed.

Specifically, the intelligent terminal obtains the current battery voltage of the system, and a specific obtaining method is well known to those skilled in the art and is not described herein again.

The intelligent terminal judges whether the acquired current battery voltage of the system is lower than a preset threshold value or not; if yes, go to step S302; if not, after the first time delay, continuously acquiring the battery voltage of the system, and judging whether the acquired battery voltage is lower than a preset threshold value.

The preset threshold is preset according to the minimum voltage value required by each hardware circuit of all chips, devices and the like in the intelligent terminal. The preset threshold is larger than the minimum voltage value required by hardware circuits such as all chips, devices and the like in the intelligent terminal. A person skilled in the art can determine the minimum voltage value of each hardware circuit such as each chip, device, and the like in the intelligent terminal according to the historical power consumption data, the empirical data, or the methods or approaches such as experimental measurement of the intelligent terminal, and further determine the preset threshold.

S302: and taking the second time delay as an interval, and discontinuously judging whether the battery voltage of the system is lower than a preset threshold value.

Specifically, after acquiring the current battery voltage of the system, the intelligent terminal judges whether the acquired current battery voltage of the system is lower than a preset threshold value; if yes, go to step S303; if not, after a second time delay, continuously acquiring the battery voltage of the system, and judging whether the acquired battery voltage is lower than a preset threshold value.

Wherein the second time delay is less than the first time delay; for example, the first time delay may be 5 seconds and the second time delay may be 3 seconds.

It can be understood that the time delay between the battery voltage of the judging system and the preset threshold value is shortened, the speed of determining that the battery is continuously in the low-power state can be increased, and the efficiency of the low-power self-protection method of the intelligent terminal is integrally improved.

Moreover, since the battery of the intelligent terminal is still in a state of net power consumption (the charged power is less than the consumed power) in the process of determining that the battery is continuously in the low power state, the battery voltage still gradually decreases along with the net power consumption. Therefore, the time consumption of the process of determining that the battery is continuously in the low-power state is shortened, the reduction amount of the battery voltage can be reduced, the probability that the battery voltage is smaller than the minimum voltage value of a hardware circuit in the intelligent terminal can be reduced, the probability of accidental passive shutdown is greatly reduced, and the reliability of low-power self-protection of the intelligent terminal is further improved.

S303: after at least one time of second time delay, if the battery voltage of the system is still lower than the preset threshold value, the battery of the intelligent terminal is confirmed to be in a low power state continuously.

Specifically, after the time delay of the first time delay, whether the battery voltage of the primary system is lower than a preset threshold value is judged; if so, continuing to judge whether the battery voltage of the next system is lower than a preset threshold value after the delay of the next second time delay; after the delay of the second time delay of the set times, the battery voltage of the system of the set times is judged to be still lower than a preset threshold value; and confirming that the battery of the intelligent terminal is continuously in a low-power state.

Wherein, the set number of times that technicians in this field can preset according to actual conditions. For example, the technician sets the set number of times to 5 in advance.

It can be understood that the intelligent terminal compares and judges the battery voltage and the preset threshold value for multiple times, and can ensure that the battery voltage is really smaller than the preset threshold value, thereby ensuring the reliability of the subsequent shutdown instruction actively executed on the intelligent terminal.

Preferably, after the time delay of the second time delay, if the battery voltage of the secondary system is judged to be not lower than the preset threshold value, the battery of the intelligent terminal is determined not to be in a low-power state continuously; ending the process, or jumping to step S301 to continue executing the next process of determining that the battery of the intelligent terminal is continuously in the low power state.

It can be understood that even if the battery voltage lower than the preset threshold is obtained before the delay of the second delay of the set times is reached due to interference and the like, whether the battery of the intelligent terminal is really in the low-power state or not can be identified in the step, and the battery is prevented from being shut down accidentally when the battery is not in the low-power state continuously, so that the reliability of active shutdown of the intelligent terminal is ensured integrally.
