With the continuous development of terminal technology, the functions of terminal equipment are more and more. In order to reasonably manage the power supply of the terminal equipment, reduce the power consumption of the terminal equipment and prolong the service life of the terminal equipment, the terminal equipment sets different power consumption modes for the power supply in different scenes. For example, in a standby situation, the terminal device sets a low power consumption mode for the power supply.
In addition, in order to ensure the safety of the power supply, an Over Current Protection (OCP) function is provided for the power supply. Different power consumption modes correspond to different OCP values. And the lower the power consumption of a power consumption mode is, the lower its corresponding OCP value is.
However, when the terminal device is in the low power consumption mode, sometimes, due to sudden increase of power consumption of a certain functional module, the current of the functional module increases and exceeds the OCP value corresponding to the low power consumption mode, so that the terminal device triggers the OCP function, and further, the system of the terminal device is crashed. Thus, the system stability of the terminal device will be affected.

Next, a software environment applied to the method for controlling the power consumption mode according to the embodiment of the present invention is described by taking an android operating system as an example.
Fig. 1 is a schematic diagram of an architecture of a possible android operating system according to an embodiment of the present invention. In fig. 1, the architecture of the android operating system includes 4 layers, which are respectively: an application layer, an application framework layer, a system runtime layer, and a kernel layer (specifically, a Linux kernel layer).
The application program layer comprises various application programs (including system application programs and third-party application programs) in an android operating system.
The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.
The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.
Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the control method of the power consumption mode provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the control method of the power consumption mode may run based on the android operating system shown in fig. 1. That is, the processor or the terminal may implement the control method of the power consumption mode provided by the embodiment of the present invention by running the software program in the android operating system.
The terminal device in the embodiment of the invention can be a mobile terminal device and can also be a non-mobile terminal device. The mobile terminal device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal device may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
The execution main body of the power consumption mode control method provided by the embodiment of the present invention may be the terminal device (including a mobile terminal device and a non-mobile terminal device), or may also be a functional module and/or a functional entity capable of implementing the method in the terminal device, and may be specifically determined according to actual use requirements, which is not limited in the embodiment of the present invention. The following takes a terminal device as an example to exemplarily describe the control method of the power consumption mode provided by the embodiment of the present invention.
Referring to fig. 2, an embodiment of the present invention provides a method for controlling a power consumption mode, which may include steps 201 to 203 described below.
In the embodiment of the invention, the target function module at least has two different power consumption modes, and the power consumption of the target function module in the different power consumption modes is different. The target function module may be at least one of a radio frequency unit, a network module, an audio output unit, an input unit, a sensor, a display unit, a user input unit, an interface unit, a memory, a processor, and the like in the terminal device, which is determined according to actual design requirements, and the embodiment of the present invention is not limited.
For example, when the terminal device is in a standby state or in other scenarios where a large current is not required, the terminal device may set the power consumption mode of a part of the function modules (target function modules) to a low power consumption mode (first power consumption mode).
Specifically, as for the method for acquiring the first current of the target function module by the terminal device, reference may be made to a related method in the prior art, and the embodiment of the present invention is not limited thereto. For example, any current protection circuit may be used to obtain the first current.
Step 202 (optional), the terminal device determines whether the first current value satisfies a first target condition.
In a case where the first current value satisfies the first target condition, the terminal device executes step 203 described below; otherwise, no processing is performed.
And under the condition that the first current value meets a first target condition, the terminal equipment switches the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode.
The first power consumption mode is any one of the power consumption modes except the power consumption mode with the largest power consumption among all the power consumption modes of the target functional module. The power consumption of the target functional module in the second power consumption mode is greater than the power consumption of the target functional module in the first power consumption mode.
For a specific method for switching the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode by the terminal device, reference may be made to related methods in the prior art, and the embodiment of the present invention is not limited thereto.
Therefore, the safety of the terminal equipment is ensured, the breakdown probability of the terminal equipment is avoided, and the stability of the system is improved.
The first target condition includes: the current value is greater than or equal to a first overcurrent protection OCP value, the OCP value corresponding to the first power consumption mode is the first OCP value, the OCP value corresponding to the second power consumption mode is a second OCP value, and the first OCP value is smaller than the second OCP value.
For example, if the first target condition is that the current value is greater than or equal to the first over-current protection OCP value, the step 202 can be specifically implemented by the following step 202a, as shown in fig. 3 in conjunction with fig. 2.
The specific terminal equipment judges whether the first current value is larger than or equal to the first OCP value or not by comparing the first current value with the first OCP value.
The specific method can refer to any existing method with a large size, and the embodiment of the invention is not limited. For example, if the determination process is implemented by a hardware circuit, the magnitude of the first current value and the magnitude of the first OCP value may be compared by a current comparator.
If the first current value is greater than or equal to the first over-current protection OCP value, the terminal device executes step 203; and if the first current value is smaller than the first overcurrent protection OCP value, the terminal equipment does not change the power consumption mode of the target function module.
The step 203 specifically includes: and under the condition that the first current value is greater than or equal to the first over-current protection OCP value, the terminal equipment switches the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode.
For example, when the terminal device determines that the first current value is greater than or equal to the first overcurrent protection OCP value, the terminal device is triggered to switch the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode by an output enable signal (the flag bit may be 0 or 1 if the terminal device is implemented by software, or the flag bit may be high or low if the terminal device is implemented by hardware, or the like).
After the terminal device switches the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode, if the first current value is greater than or equal to the second OCP value, the terminal device may continue to switch the power consumption mode of the target function module to the power consumption mode with a larger OCP value (which may be a step-by-step switch or a cross-step switch, which is not limited in the embodiments of the present invention, for example, switch from the second power consumption mode to the third power consumption mode, the second power consumption mode is not the power consumption mode with the largest power consumption among all the power consumption modes of the target function module, until the power consumption mode of the target function module is switched to the power consumption mode corresponding to the OCP value with the smaller first current value, and if the terminal device switches the power consumption mode of the target function module to the power consumption mode with the largest power consumption, the first current value is greater than or equal to the OCP value corresponding to the largest power consumption mode, the terminal device may stop supplying power to the function module.
For example, the second power consumption mode is a power consumption mode with the largest power consumption among all power consumption modes of the target functional module, and as shown in fig. 4 in conjunction with fig. 3, after step 203, the method for controlling the power consumption mode according to the embodiment of the present invention may further include the following steps 204 to 205.
Step 204 (optional), the terminal device determines whether the first current value is greater than or equal to the second OCP value.
The specific terminal equipment judges whether the first current value is larger than or equal to the second OCP value or not by comparing the first current value with the second OCP value.
The specific method can refer to any existing method with a large size, and the embodiment of the invention is not limited. For example, if the determination process is implemented by a hardware circuit, the magnitude of the first current value and the magnitude of the second OCP value may be compared by a current comparator.
If the first current value is greater than or equal to the second OCP value and the second power consumption mode is the power consumption mode with the maximum power consumption among all the power consumption modes of the target functional module, it indicates that the power consumption mode of the target functional module is the power consumption mode with the maximum power consumption, and the terminal device cannot continue to switch (adjust), and then executes the following step 205; if the first current value is smaller than the second OCP value, it is not limited herein.
And step 205, the terminal equipment stops supplying power to the target function module.
And under the condition that the first current value is larger than or equal to the second OCP value, the terminal equipment stops supplying power to the target function module. I.e. to cut off the power supply to the target functional module. Powering off the target function module may cause the terminal device to crash, for example, causing a system restart of the terminal device or causing the terminal device to shut down.
When the power consumption mode of the target function module is switched to the power consumption mode with the maximum power consumption, if the first current value is greater than or equal to the OCP value corresponding to the power consumption mode with the maximum power consumption, it indicates that the previous power consumption mode cannot be switched any more, and at this time, in order to ensure the safety of a circuit, a power supply and the like, the power supply of the target function module needs to be stopped.
Optionally, the first target condition further includes: the current value is less than the second OCP value.
For example, if the first target condition is that the current value is greater than or equal to the first over-current protection OCP value and the current value is less than the second OCP value, the step 202 can be specifically implemented by the following step 202b, as shown in fig. 5 in conjunction with fig. 2.
In step 202b (optional), the terminal device determines whether the first current value is greater than or equal to the first overcurrent protection OCP value and smaller than the second OCP value.
The terminal equipment judges whether the first current value is larger than or equal to the first OCP value and smaller than the second OCP value by comparing the first current value with the first OCP value and comparing the first current value with the second OCP value.
The specific implementation method can refer to any existing method with a large size, and the embodiment of the invention is not limited. For example, if the determination process is implemented by a hardware circuit, the first current value and the first OCP value may be compared by a current comparator, and the first current value and the second OCP value may be compared by a current comparator.
If the first current value is greater than or equal to the first overcurrent protection OCP value and less than the second OCP value, the terminal device executes step 203; if the first current value is smaller than the first overcurrent protection OCP value, the terminal equipment does not change the power consumption mode of the target function module; if the first current value is greater than the second OCP value, it is not limited herein.
The step 203 specifically includes: and under the condition that the first current value is greater than or equal to the first over-current protection OCP value and the first current value is smaller than the second OCP value, the terminal equipment switches the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode.
Illustratively, when the terminal device determines that the first current value is greater than or equal to the first overcurrent protection OCP value and less than the second OCP value, the terminal device is triggered to switch the power consumption mode of the target function module from the first power consumption mode to the second power consumption mode by an output enable signal (the flag bit is 0 or 1 if the current value is software implementation, the flag bit is high level or low level if the current value is hardware implementation, or the like).
Therefore, the terminal equipment can accurately judge whether the power consumption mode of the target function module is switched, and the power consumption mode is switched to, or the power supply to the target function module is stopped. Compared with the method provided by the steps 202a to 203, the method can be switched to the corresponding power consumption mode in one step, or the power supply to the target function module is stopped.
For example, referring to fig. 5, as shown in fig. 6, after the step 202b determines that the first current value is not greater than or equal to the first OCP value and is less than the second OCP value, the method for controlling the power consumption mode according to the embodiment of the present invention may further include the following steps 206 to 207.
In step 206 (optional), the terminal device determines whether the first current value is greater than or equal to the third OCP value.
And the specific terminal equipment judges whether the first current value is greater than or equal to the third OCP value or not by comparing the first current value with the third OCP value.
The specific method can refer to any existing method with a large size, and the embodiment of the invention is not limited. For example, if the determination process is implemented by a hardware circuit, the magnitude of the first current value and the magnitude of the third OCP value may be compared by a current comparator.
The third OCP value is an OCP value corresponding to a third power consumption mode, the third power consumption mode is a power consumption mode with the largest power consumption in all power consumption modes of the target function module, and the first OCP value is smaller than the third OCP value.
If the first current value is greater than or equal to the third OCP value, it indicates that the first current value is greater than the OCP value corresponding to any power consumption mode of the target functional module, and the terminal device executes step 207 described below.
And step 207, the terminal equipment stops supplying power to the target function module.
And under the condition that the first current value is larger than or equal to the third OCP value, the terminal equipment stops supplying power to the target function module.
If the first current value is greater than or equal to the OCP value corresponding to the power consumption mode with the maximum power consumption, the power supply is cut off to stop supplying power to the target function module in order to ensure the safety of the circuit, the power supply and the like.
Compared with the method provided in the steps 204 to 205, the method can directly judge whether the power supply to the target function module needs to be stopped, and when the power supply to the target function module needs to be stopped, the method can quickly judge and cut off the power supply, so that the safety of the target function module or the power supply is ensured, and the safety of the terminal equipment is improved.
Illustratively, in conjunction with fig. 2, as shown in fig. 7, after step 203, the method for controlling the power consumption mode according to the embodiment of the present invention may further include steps 208 to 210 described below.
And step 208, after the preset time length, the terminal device acquires the first current value again.
The preset time length is preset in advance by the terminal device, and the preset time length can be any feasible time length and is specifically set according to actual needs, and the embodiment of the invention is not limited.
The first current value obtained again is the current value obtained by the terminal device at the same position but different time points.
The method for the terminal device to reacquire the first current value refers to the method for the terminal device to acquire the first current value, and is not described herein again.
Step 209 (optional), the terminal device determines whether the retrieved first current value is less than or equal to the first OCP value.
And the terminal equipment judges whether the first current value is smaller than the first OCP value or not by comparing the first current value with the first OCP value.
The specific implementation method can refer to any existing method with a large size, and the embodiment of the invention is not limited. For example, if the determination process is implemented by a hardware circuit, the magnitude of the first current value and the magnitude of the first OCP value may be compared by a current comparator.
If the retrieved first current value is less than or equal to the first OCP value, the terminal device performs step 210 described below; if the retrieved first current value is greater than the first OCP value, this is not limited herein.
And under the condition that the obtained first current value is less than or equal to the first OCP value, the terminal equipment switches the power consumption mode of the target function module from the second power consumption mode to the first power consumption mode.
The second power consumption mode is switched to the first power consumption mode, for example, the working mode can be changed from a pulse width modulation mode to a pulse density modulation mode, so that the power supply capacity of the power supply can be reduced, and the power consumption of the target functional module can be reduced.
Therefore, when the first current value obtained again after the preset duration is smaller than the first OCP value, the fact that the first current value exceeds the first OCP value only accidentally and temporarily is indicated, and the power consumption mode of the target function module is switched from the second power consumption mode to the first power consumption mode, so that the power consumption of the terminal device is reduced, and electric energy can be saved.
It should be noted that: the control method of the power consumption mode provided by the embodiment of the invention can reduce the probability of terminal equipment breakdown (system restart or crash) and improve the stability of the system; moreover, the production requirement on the power management chip (IC) can be reduced, the yield of the power management chip is improved, and the production cost of the power management chip is reduced. The control method of the power consumption mode provided by the embodiment of the present invention may be implemented by software, or may be implemented by a hardware circuit, and may be, for example, any hardware circuit that can use the above method as a working principle, and the embodiment of the present invention is not limited.
The embodiment of the invention provides a control method of a power consumption mode, wherein terminal equipment can obtain a first current value of a target function module in the terminal equipment; switching the power consumption mode of the target function module from a first power consumption mode to a second power consumption mode if the first current value satisfies a first target condition, the first target condition including: the current value is greater than or equal to a first overcurrent protection OCP value, the OCP value corresponding to the first power consumption mode is the first OCP value, the OCP value corresponding to the second power consumption mode is a second OCP value, and the first OCP value is smaller than the second OCP value. Through the scheme, when the power consumption of the target function module is increased suddenly and the current of the target function module exceeds the OCP value corresponding to the low power consumption mode, the power consumption mode of the target function module is switched from the low power consumption mode to the high power consumption mode by the terminal equipment, the OCP function is prevented from being triggered by the terminal equipment to a certain extent, and the system breakdown of the terminal equipment is caused.
