Description

Power Management Method for Portable Devices

technical field

The invention relates to a power management method of a portable device.

Background technique

With the development of technology, the functions of portable devices such as smart phones, notebook computers, and personal digital assistants (Personal Digital Assistance, PDA) are also becoming more and more diverse. The portable device can execute different application programs through its built-in hardware modules, thereby providing functions such as calling, surfing the Internet, taking pictures, taking photos, playing video and audio, or global positioning.

The biggest advantage of portable devices is that they are easy to carry, but their power supply is limited. For the power management of all hardware components in the portable device when not in use, the prior art pre-plans to completely shut them down or enter a power saving mode, instead of flexibly and dynamically performing power management according to user habits.

Contents of the invention

The present invention provides a power management method of a portable device, which includes detecting the historical usage status of hardware components in the portable device; determining the usage level of the hardware component according to the historical usage status; and adjusting the supply to the hardware according to the usage level power supply for the component.

The present invention can automatically adjust the corresponding power supply at any time according to the historical usage status of each hardware component in the portable device, and periodically update the historical usage status, thereby providing the best power control environment in line with the latest habits of current users.

Detailed ways

The invention utilizes the system terminal (OS) of the portable device to detect the historical use status of each hardware component, and automatically provides the best power control environment in line with the current user's habit after obtaining the current user's habit.

1 is a flowchart of a power management method for a portable device in the present invention, which includes the following steps:

Step 110: Detect historical usage status of specific hardware components in the portable device.

Step 120: Determine the usage level of the specific hardware component according to the historical usage status.

Step 130: Determine whether data needs to be updated: if yes, execute step 110; if not, execute step 140.

Step 140 : Automatically adjust the power supplied to the specific hardware component according to the usage level of the specific hardware component.

In step 110, the specific hardware component may be a global positioning system (global positioning system, GPS) device, a bluetooth device, a wireless fidelity (wireless fidelity, WiFi) device or a third generation mobile communication technology (third generation, 3G) devices and other high power consumption components. The present invention can detect the number of times and time when each hardware component in the portable device is turned on within a predetermined period, and then obtain the historical usage status corresponding to each hardware component.

In step 120, the present invention can determine the usage level of the specific hardware component according to the historical usage status of the specific hardware component. For example, if the specific hardware component is often turned on or turned on for a long time within a predetermined period, the specific hardware component may be determined as a heavily used hardware component for the current user; If it is rarely turned on or turned on for a short period of time during the predetermined period, this specific hardware component can be judged as a lightly used hardware component for the current user; The hardware component is determined to be a moderately used hardware component.

In step 130, the present invention can determine whether data needs to be updated, for example, jumping back to step 110 periodically. In this way, if the user changes his habit or the portable device is transferred to another person for some reason, step 130 can update the historical usage status of the specific hardware component, so that the usage level determined in step 120 can match the recent usage habits of the current user.

When the portable device is in operation, the operation modes of each hardware component are roughly divided into normal mode, power saving mode and shutdown mode. In the normal mode, a preset power supply is provided to keep the hardware components in normal working condition at any time, and the power consumption is the most at this time. In shutdown mode, the power supply is completely turned off, and no power is consumed at this time, but it takes a wake-up time to return to normal operation when restarting. Depending on the definition of different systems or manufacturers, the power saving mode can have different names such as standby, hibernation or sleep mode, but the principle is to only provide the minimum power supply required to save data, so the power consumption of the power saving mode is lower than that of the normal mode , and requires a shorter wake-up time than off mode when restarting.

In step 140, the present invention can automatically adjust the power supplied to the specific hardware component according to the usage level of the specific hardware component. For example, if it is determined in step 120 that it is a heavily used hardware component, it means that the current user will often use this specific hardware component. At this time, the present invention will perform step 140A to enter the normal mode; if it is determined in step 120 If it is a moderately used hardware component, it means that the current user will occasionally use this specific hardware component. At this time, the present invention will execute step 140B to enter the power saving mode; if it is determined to be a lightly used hardware component in step 120, it means The current user seldom uses this specific hardware component, and at this time, the present invention executes step 140C to enter the shutdown mode.

According to the historical use status, the user has a high probability of using the heavily used hardware components, so the present invention will maintain the power supply to the heavily used hardware components in step 140A, so that it can be in a normal working state at any time, so there is no need for any The wake-up time can respond to the instructions issued by the user.

According to the historical usage status, the probability of the user using the moderately used hardware components is medium, so the present invention will reduce the power supplied to the moderately used hardware components in step 140B to achieve partial power saving effect and shorten the wake-up time In order to balance power saving and system performance at the same time.

According to the historical usage status, the probability of the user using the lightly used hardware components is very low, so the present invention will completely turn off the power supply to the lightly used hardware components in step 140C to achieve the best power saving effect, even if the received With few restart instructions, the extra wake-up time does not significantly affect the performance of the portable device.

The present invention can automatically adjust the corresponding power supply according to the historical use status of each hardware component in the portable device at any time, and regularly update the historical use status, thereby providing the best power control environment in line with the latest habits of current users.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
