Background

In electronic devices, power sources typically include peripheral power sources and system power sources. The external power supply can supply power for electronic elements such as a camera, a loudspeaker, a microphone, a flash lamp, a display screen, a radar and the like in the electronic equipment. The system power supply may power electronic components such as processors, memory, etc. in the electronic device.

Currently, in the case that the load current exceeds a current threshold corresponding to the operation mode of the power supply, the electronic device may trigger an over-current protection (over current protection, OCP) function of the power supply to avoid power supply damage.

Therefore, after the overcurrent protection function of the power supply is triggered, the mode of the power supply is adjusted, the overcurrent protection triggered by the power supply is avoided as much as possible, and the use experience of a user is ensured.

With reference to the first aspect, in certain implementations of the first aspect, after triggering an over-current protection function of the power supply, determining the second mode from the plurality of modes includes:

In the method, after the overcurrent protection function of the power supply is triggered, the current mode of the power supply can be determined, and the mode of the power supply is gradually adjusted to the highest level from the mode of one level higher than the current mode, namely, the mode of one level higher than the current mode is adjusted step by step, so that the condition that the power consumption of the electronic equipment is caused due to the fact that the level of the mode of one-time adjustment is too high is avoided. With reference to the first aspect, in certain implementations of the first aspect, the method further includes:

the third mode is determined as the first mode.

In the method, since the level corresponding to the third mode is the lowest level corresponding to the plurality of modes, the corresponding current threshold is the lowest current threshold corresponding to the plurality of modes, and when the mode with the lowest level is determined as the first mode, the power supply is electrified according to the set first mode, the voltage of the electronic equipment is unchanged, the current threshold is reduced, the power consumption is reduced, and the effect of saving electricity can be achieved.

when the short-circuit fault data of the power supply indicates that the power supply has an excessive short-circuit fault, the power supply is not powered on.

Fig. 2 is a schematic diagram of an electronic device according to an embodiment of the application. When the eye movement data processing method provided by the embodiment of the present application is applied to the electronic device 100 shown in fig. 1, software in the electronic device 100 may be divided into an application layer 201, a hardware abstraction layer (Hardware Abstraction Layer, HAL) 202 and a driver layer 203 as shown in fig. 2.

Based on the above description of the scenario, the electronic device is taken as an example, and the method for preventing triggering over-current protection provided by the embodiment of the application is described in detail with reference to the accompanying drawings and application scenario.

Referring to fig. 3, fig. 3 is a flow chart illustrating a method for preventing triggering of over-current protection according to an embodiment of the application.

As shown in fig. 3, the method for preventing triggering over-current protection provided by the present application may include:

s101, powering up the power supply according to the set first mode.

The first mode is any one of a plurality of modes, the plurality of modes correspond to different current thresholds, and the plurality of modes correspond to different levels.

For example, the plurality of modes is 7 modes, which are mode 1, mode 2, mode 3, mode 4, mode 5, mode 6, and mode 7, respectively.

Correspondingly, the level of mode 1 is 1, the level of mode 2 is 2, the level of mode 3 is 3, the level of mode 4 is 4, the level of mode 5 is 5, the level of mode 6 is 6, and the level of mode 7 is 7.

The current thresholds corresponding to the 7 modes are:

the current threshold corresponding to the mode 1 is 50mA, the current threshold corresponding to the mode 2 is 100mA, the current threshold corresponding to the mode 3 is 150mA, the current threshold corresponding to the mode 4 is 200mA, the current threshold corresponding to the mode 5 is 250mA, the current threshold corresponding to the mode 6 is 300mA, and the current threshold corresponding to the mode 7 is 350mA.

The current threshold value corresponding to each mode is not particularly limited in the present application.

The first mode may be any one of the 7 modes described above.

For example, when the first mode is mode 1, the electronic device may power up the power supply according to mode 1.

In addition, the system power supply may include multiple power supplies, and the peripheral power supply may include multiple power supplies.

The power supply can be any power supply in the system power supply or any power supply in the peripheral power supply.

For example, the power supply may be a peripheral power supply that supplies power to a camera in the electronic device.

In some embodiments, the load current conditions of each power supply of the system power supply or the peripheral power supply may be different, and some power supplies have larger load current and some power supplies have smaller load current, so that the electronic device can associate multiple modes for each power supply according to the load condition and the load carrying capacity of the power supply, and is convenient to set a corresponding mode according to the load condition of the power supply.

When the power supply is a peripheral power supply for supplying power to a camera in the electronic equipment, the load is the camera, the output current of the camera is 40mA, then the current threshold value of the overcurrent protection corresponding to the power supply for supplying power to the camera can be 50mA, and the load carrying capacity of the power supply is low.

When the power supply is a peripheral power supply for supplying power to a display screen in the electronic equipment, the load is the display screen, the output current of the display screen is 180mA, then the current threshold value of the overcurrent protection corresponding to the power supply for supplying power to the display screen can be 200mA, and the load carrying capacity of the power supply is general.

If the power supply is a system power supply for supplying power to a processor in the electronic equipment, the load is the processor, the output current of the processor is 345mA, then the current threshold value of the overcurrent protection corresponding to the power supply for supplying power to the processor can be 350mA, and the load carrying capacity of the power supply is higher.

Therefore, the electronic equipment can be used for associating a plurality of modes with different current thresholds for each power supply, so that the modes can meet the overcurrent protection requirements of different power supplies.

In addition, when the electronic equipment powers on the power supply according to the set first mode, the current threshold corresponding to the overcurrent protection function of the electronic equipment triggering the power supply is the current threshold corresponding to the first mode.

For example, when the first mode is a mode 1 with a level 1, and when the current threshold corresponding to the mode 1 with a level 1 is 50mA, the electronic device may trigger the OCP function of the power supply when the load current exceeds 50mA, and the electronic device may not trigger the OCP function of the power supply when the load current does not exceed 50 mA.

S102, after triggering an overcurrent protection function of the power supply, determining a second mode from the plurality of modes.

The current threshold corresponding to the second mode is higher than the current threshold corresponding to the first mode.

In some embodiments, the second mode is a higher level mode than the first mode.

When the level of the second mode is higher than the level of the first mode, the current threshold may be increased by one level with the level of the second mode.

Assuming that the plurality of modes are 7 modes, the first mode is mode 1 with a level 1, and the current threshold corresponding to mode 1 with a level 1 is 50mA.

Then, after the electronic device powers up the power supply according to the mode 1 and triggers the overcurrent protection function of the power supply, the electronic device may determine a mode one level higher than the level of the mode 1, for example, the mode 2, from among the 7 modes, since the mode 1 is the lowest level mode.

In other embodiments, the second mode is a mode that is higher than any one level of the first mode.

The level of the second mode may be determined according to the current threshold corresponding to the first mode, and the current threshold of the second mode may be greater than the current threshold of the first mode.

Then, after the electronic device powers up the power supply according to the mode 1 and triggers the overcurrent protection function of the power supply, the electronic device may determine a mode higher than the mode 1 by two levels, for example, a mode 3, from the 7 modes because the mode 1 is the lowest level mode.

It can be seen that after triggering the over-current protection function of the power supply, the electronic device does not power down the power supply, but re-determines the power-up mode.

And S103, updating the first mode into the second mode, and continuously executing S101 until the overcurrent protection function of the power supply is not triggered.

Based on S102, after determining the second mode from the plurality of modes, the electronic device may update the first mode to the second mode, and continue to perform the step of powering up the power supply according to the set first mode.

After triggering the over-current protection of the power supply, the electronic device may determine a second mode from the plurality of modes, update the first mode to the second mode, and execute S101-S103 in a loop until the over-current protection function of the power supply is not triggered.

Assuming that the first mode is a mode 1 with a level of 1, the second mode is a mode 2 with a level of 2, the current threshold corresponding to the mode 1 is 50mA, and the current threshold corresponding to the mode 2 is 100mA.

The electronic equipment powers on the power supply according to the mode 1, the load current exceeds 50mA of the power supply, and after the OCP function of the power supply is triggered, the electronic equipment can determine the mode 2 with the grade of 2 from a plurality of modes, and the mode 1 is updated to be the mode 2.

And the electronic equipment continues to electrify the power supply according to the mode 1, at the moment, the current threshold of the power supply is 100mA, the load current does not exceed 100mA of the power supply, and the OCP function of the power supply is not triggered.

Therefore, the electronic equipment is powered on according to the first mode, after the overcurrent protection function of the power supply is triggered, the electronic equipment can be prevented from being directly powered off for protection, the problem that the electronic equipment cannot be used due to restarting and the like is avoided, and a second mode except the first mode is determined from the multiple modes, and the electronic equipment is powered on again until the overcurrent protection function of the power supply is not triggered by the electronic equipment.

The method for preventing the triggering of the over-current protection comprises the steps that the electronic equipment powers on a power supply according to the set first mode, determines the second mode from a plurality of modes after triggering the over-current protection function of the power supply, updates the first mode into the second mode, and continues to execute the step of powering on the power supply according to the set first mode until the electronic equipment does not trigger the over-current protection function of the power supply. Therefore, after the overcurrent protection function of the power supply is triggered, the electronic equipment does not directly power down the power supply, but rather determines the power-up mode of the power supply again, so that the level of the power-up mode of the power supply is improved, the corresponding current threshold is improved, and the load current is not easy to exceed the current threshold. Therefore, after the overcurrent protection function of the power supply is triggered, the overload capacity of the electronic equipment is improved, so that the overcurrent protection fault of the electronic equipment is repaired, the overcurrent protection function of the power supply is prevented from being triggered as much as possible, the stability of the electronic equipment is improved, and the use experience of a user is ensured.

Based on the description of the embodiment shown in fig. 3 above, when the electronic device determines the second mode from among the plurality of modes after triggering the overcurrent protection function of the power supply, the electronic device may determine step by step from a mode higher than the first mode by one step according to the level of each mode.

Next, a detailed implementation procedure of the method for preventing triggering of the over-current protection according to the present application will be described with reference to fig. 4.

Referring to fig. 4, fig. 4 is a flowchart illustrating a method for preventing triggering of an over-current protection according to an embodiment of the application.

As shown in fig. 4, the method for preventing triggering over-current protection provided by the present application may include:

s201, powering up the power supply according to the set first mode.

The implementation of S201 is similar to that of S101 in the embodiment shown in fig. 3, and will not be described herein.

S202, judging whether to trigger an overcurrent protection function of the power supply.

After the overcurrent protection function of the power supply is not triggered each time, the electronic device can execute S203; after triggering the over-current protection function of the power supply, the electronic device may execute S204.

And S203, when the overcurrent protection function of the power supply is not triggered, storing a first mode for powering up the power supply currently in a second register of the power supply.

The electronic equipment powers on the power supply according to the set first mode, does not trigger an overcurrent protection function of the power supply, and indicates that the load current of the power supply does not exceed a current threshold corresponding to the first mode.

Therefore, the electronic equipment can store the first mode of powering on the power supply in the second register of the power supply, so that the electronic equipment can power on the power supply directly according to the set first mode at the next time.

For example, when the electronic device powers on the power supply of the camera according to the first mode and does not trigger the overcurrent protection function of the power supply of the camera, the electronic device can store the first mode in the second register of the power supply of the camera, so that the electronic device can power on the power supply of the camera according to the first mode in the process of using the camera next time by a user.

S204, after triggering the overcurrent protection function of the power supply, determining the first mode as the current mode of the power supply.

Typically, the current mode of the power supply is the first mode in S201.

The electronic equipment powers on the power supply according to the set first mode, and after the overcurrent protection function of the power supply is triggered, the mode of the power supply can be determined to be the current mode of the power supply when the overcurrent protection function of the power supply is triggered, so that preparation is made for determining whether to update the current mode according to the grade corresponding to the current mode.

In addition, in the whole process, the process of powering up the power supply by the electronic device according to the set first mode and the process of acquiring the current mode of the power supply are not the same process, so that the electronic device can determine the current mode of the power supply after triggering the overcurrent protection function of the power supply in order to ensure the effectiveness.

S205, judging whether the current mode is the highest-level mode in the modes.

When the level corresponding to the current mode of the power supply is less than the highest level corresponding to the plurality of modes, the electronic device may execute S206; when the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the plurality of modes, the electronic device may perform S207.

S206, when the level corresponding to the current mode of the power supply is smaller than the highest level corresponding to the modes, determining a mode which is one level higher than the current mode of the power supply in the modes as a second mode.

Let the plurality of modes be 7 modes, namely mode 1, mode 2, mode 3, mode 4, mode 5, mode 6 and mode 7, respectively, and the current mode is mode 1. The level of mode 1 is 1, the level of mode 2 is 2, the level of mode 3 is 3, the level of mode 4 is 4, the level of mode 5 is 5, the level of mode 6 is 6, and the level of mode 7 is 7.

Then, the mode one level higher than the level of the mode 1 is the mode 2, and the electronic device may determine the mode 2 as the second mode.

The electronic device determines a mode which is one level higher than the current mode of the power supply in the multiple modes as the second mode, so that the situation that the power consumption of the electronic device is caused by the fact that the level of the mode which is adjusted at one time is too high can be avoided.

S207, when the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the modes, recording the first times.

The first time is the total time for triggering the overcurrent protection function of the power supply.

Let the plurality of modes be 7 modes, namely mode 1, mode 2, mode 3, mode 4, mode 5, mode 6 and mode 7, respectively, the highest level of the mode 7 corresponding to the mode being 7.

When the current mode of the power supply is mode 7, the electronic device may record a total number of times that the over-current protection function of the power supply is triggered.

That is, the electronic device can record the total number of times the power supply is powered on in the highest-level mode, triggering the overcurrent protection function.

Thus, the electronic device may record the first number of times as 1 when it is determined for the first time that the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the plurality of modes.

The electronic device may record the first number as 2 when the second time determines that the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the plurality of modes.

It can be seen that when the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the plurality of modes, the electronic device cannot adjust the mode of the higher level any more, and the electronic device can not redefine the second mode from the plurality of modes.

In some embodiments, when the first number is greater than or equal to the preset number, it is determined that the power supply has a short circuit fault, and a short circuit fault identification of the power supply is stored in a first register of the power supply.

The short-circuit fault identification of the power supply is used for indicating that the power supply has an over-short-circuit fault.

The preset times are preset, and can be set according to actual conditions.

For example, the preset number of times may be 5 times.

Assume that the preset number of times is 5.

Then, the electronic device may determine that the power supply has a short circuit fault when the first number of times is 5, and store a short circuit fault identification of the power supply in a first register of the power supply.

The first time number indicates the number of times that the power supply triggers over-current protection when the electronic equipment powers on the power supply according to the mode with the highest grade.

The electronic equipment powers on the power supply according to the mode with the highest grade, and when the number of times of triggering over-current protection by the power supply is greater than or equal to the preset number of times, the electronic equipment can determine that the power supply has indeed generated a short circuit fault.

Therefore, the situation that the electronic equipment judges that the power supply hardware has a short circuit fault due to the fact that the instantaneous current of the load of the power supply is too large when the electronic equipment powers on the power supply according to the mode with the highest grade can be avoided.

S208, powering down the power supply.

When the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the modes, the electronic equipment records the first times and powers down the power supply.

When the level of the current mode is the highest level, the electronic equipment also triggers the overcurrent protection function of the power supply, and at the moment, the electronic equipment can not adjust the mode with the higher level any more, and can directly power down the power supply.

S209, updating the first mode into the second mode, and continuing to execute S201 until the overcurrent protection function of the power supply is not triggered.

The implementation of S201 is similar to that of S103 in the embodiment shown in fig. 3, and will not be described herein.

In the application, when the overcurrent protection function of the power supply is not triggered, the first mode for powering on the power supply is stored in the second register of the power supply, so that the electronic equipment can conveniently power on the power supply according to the first mode stored in the second register next time.

After the overcurrent protection function of the power supply is triggered, the current mode of the power supply can be determined, when the level corresponding to the current mode of the power supply is smaller than the highest level corresponding to the modes, the mode higher than the current mode of the power supply by one level in the modes is determined to be the second mode, and the electronic equipment starts to adjust from the mode higher than the current mode by one level, so that the condition that the power consumption of the electronic equipment is caused due to the fact that the level of the mode adjusted at one time is too high is avoided.

In addition, after the electronic equipment triggers the overcurrent protection function of the power supply, the current mode of the power supply can be determined, when the grade corresponding to the current mode of the power supply is equal to the highest grade corresponding to a plurality of modes, the first times are recorded, the power supply is powered down, and the power supply is powered up according to the highest grade mode.

Based on the description of fig. 3 and 4 above, the electronic device may determine the mode with the smallest rank as the first mode before powering up the power supply in the set first mode.

Next, a detailed implementation procedure of the method for preventing triggering of the over-current protection according to the present application will be described with reference to fig. 5.

Referring to fig. 5, fig. 5 is a flowchart illustrating a method for preventing triggering of an over-current protection according to an embodiment of the application.

As shown in fig. 5, the method for preventing triggering over-current protection provided by the present application may include:

s301, acquiring short-circuit fault data of a power supply.

The short-circuit fault data of the power supply are used for indicating whether the power supply has an over-short-circuit fault or not.

In some embodiments, the short circuit fault data for the power supply includes: and the electronic equipment can determine whether the power supply has the fault identification according to whether the short circuit fault identification of the power supply is stored in the first register of the power supply.

When the short-circuit fault identification of the power supply is stored in the first register of the power supply, the electronic equipment can determine that the short-circuit fault data of the power supply indicate that the power supply has an excessive short-circuit fault; when the short-circuit fault identification of the power supply is not stored in the first register of the power supply, the electronic device may determine that the short-circuit fault data of the power supply indicates that the power supply has not failed.

In some embodiments, the fault identification may be represented by a binary number.

For example, when the binary number stored in the first register of the power supply is 1, the electronic device determines that the power supply has an over-short fault; when the binary number stored in the first register of the power supply is 0, the electronic device determines that the power supply has not failed due to a short circuit.

S302, judging whether an over-short circuit fault occurs.

When the short-circuit fault data of the power supply indicates that the power supply has an excessive short-circuit fault, the electronic device may execute S303; when the short-circuit fault data of the power supply indicates that the power supply has not failed the short-circuit fault, the electronic device may perform S304.

S303, when the short-circuit fault data of the power supply indicates that the power supply has failed due to a short-circuit, the power supply is not powered on.

The electronic equipment can not power up the power supply when the short-circuit fault data of the power supply indicate that the power supply has an excessive short-circuit fault, and the problem that the electronic equipment cannot be used due to restarting and the like of the electronic equipment caused by the power supply power up under the condition that the power supply has the excessive short-circuit fault is avoided.

S304, when the short-circuit fault data of the power supply indicate that the power supply has not failed in short-circuit, determining a third mode from the plurality of modes.

The level corresponding to the third mode is the lowest level corresponding to the plurality of modes, that is, the current threshold corresponding to the third mode is the minimum current threshold corresponding to the plurality of modes.

The plurality of modes are assumed to be 7 modes, namely mode 1, mode 2, mode 3, mode 4, mode 5, mode 6 and mode 7, respectively, and the level of mode 1 is 1 level and is the lowest level.

Then, when the short-circuit failure data of the power supply indicates that the power supply has not failed in short-circuit, the electronic device may determine the lowest level mode 1 from among the 7 modes.

S305, determining the third mode as the first mode.

Based on S304, the electronic device may determine a lowest-level mode corresponding to the plurality of modes, and thus, the electronic device may determine the lowest-level mode as the first mode.

Let the plurality of modes be 7 modes, and the mode of the lowest level be mode 1.

Then, the electronic device may determine mode 1 as the first mode.

S306, powering up the power supply according to the set first mode.

S307, judging whether to trigger the overcurrent protection function of the power supply.

And S308, storing a first mode for powering up the power supply in a second register of the power supply every time after the overcurrent protection function of the power supply is not triggered.

S309, after triggering the overcurrent protection function of the power supply, determining the current mode of the power supply according to the current threshold corresponding to the power supply when triggering the overcurrent protection function of the power supply.

S310, judging whether the current mode is the mode with the highest level in a plurality of modes.

S311, when the level corresponding to the current mode of the power supply is equal to the highest level corresponding to the modes, recording the first times.

S312, powering down the power supply.

S313, determining a mode which is one level higher than the current mode of the power supply in the plurality of modes as a second mode.

S314, updating the first mode into the second mode, and continuously executing the step of powering on the power supply according to the set first mode until the overcurrent protection function of the power supply is not triggered.

The implementation manners of S306-S314 are similar to those of S201-S209 in the embodiment shown in fig. 4, and are not repeated here.

In the application, when the short-circuit fault data of the power supply indicate that the power supply has an excessive short-circuit fault, the electronic equipment powers down the power supply, and when the power supply has the excessive short-circuit fault, the electronic equipment determines that the hardware of the power supply is damaged, so that the power supply can not be powered up, and the problems that the electronic equipment cannot be used due to restarting and the like caused by triggering the excessive current protection function of the power supply again when the power supply has the excessive short-circuit fault are avoided.

When the short-circuit fault data of the power supply indicates that the power supply has not failed due to short-circuit, the electronic device determines a third mode from the plurality of modes, and determines the third mode as the first mode, and since the level corresponding to the third mode is the lowest level corresponding to the plurality of modes, and the corresponding current threshold is the lowest current threshold corresponding to the plurality of modes, when the power supply is powered on according to the mode with the lowest level, the voltage of the electronic device is unchanged, the current threshold is reduced, the power consumption is reduced, and the electronic device can achieve the effect of saving power.

1. the electronic equipment is a mobile phone;

2. the plurality of modes is 7 modes, which are mode 1, mode 2, mode 3, mode 4, mode 5, mode 6, and mode 7, respectively.

3. The level of mode 1 is 1, the level of mode 2 is 2, the level of mode 3 is 3, the level of mode 4 is 4, the level of mode 5 is 5, the level of mode 6 is 6, and the level of mode 7 is 7.

4. The current thresholds corresponding to the 7 modes are: the current threshold corresponding to the mode 1 is 50mA, the current threshold corresponding to the mode 2 is 100mA, the current threshold corresponding to the mode 3 is 150mA, the current threshold corresponding to the mode 4 is 200mA, the current threshold corresponding to the mode 5 is 250mA, the current threshold corresponding to the mode 6 is 300mA, and the current threshold corresponding to the mode 7 is 350mA.
