Description

Terminal power saving method, device, terminal, computer program and carrier

The present invention relates to the field of mobile communications, and in particular, to a terminal power saving method, device, terminal, computer program and carrier. Background technique

At present, smart phones have been widely used in the world. The trend of smartphone development is that screens are getting bigger and bigger, functions are getting more and more, and application software is getting more and more. The power consumption of smartphones is also increasing. In the past, it was not surprising that non-smart phones could work for a week due to their single function and small screen. Today, smartphones need almost a day. The short use of smartphones has become one of the most serious problems limiting the user experience.

Among the existing smart machine power saving solutions of the related art, the most common one is to use a light sensor to adjust the backlight brightness of an LCD (Liquid Crystal Display) in real time, and to use a proximity sensor to turn off the touch screen during a call. LCD backlight. The former uses the light sensor to detect the brightness of the external environment, and adjusts the brightness of the LCD backlight in real time, such as reducing the brightness of the LCD backlight in a dark state to achieve power saving. The latter is to use the proximity sensor to judge the mobile phone to contact the face during the user's call, turn off the touch screen to avoid misoperation, and turn off the LCD backlight to save power. In the above two ways, the power consumption of the mobile phone can be reduced to a certain extent, but the power saving situation of the application scenario of the smart machine with large power consumption is not considered.

Tests have found that smart phones consume a lot of power in applications such as taking photos, videos, playing videos, games, etc., which is 2 to 3 times the power consumption of common applications such as watching web pages and listening to music, reducing these high-power applications. The power consumption in the scene will bring good results. At present, Android and other operating systems open the camera and play video and other applications, and will not perform the user-set no-operation sleep time. If the user forgets to turn off the high-power application such as camera and video, it will cause a lot of battery power for a long time. Big waste, but directly at the expense of lowering the quality of application execution, such as video playback quality or camera, camera quality Volume, reducing the power consumption of large applications has a poor impact on the user experience.

Corresponding to the terminal power saving method introduced in the foregoing embodiment, this embodiment provides a terminal power saving The device can be disposed on the terminal side to implement the above embodiment. 2 is a structural block diagram of a power saving device for a terminal according to an embodiment of the present invention. As shown in FIG. 2, the device includes: a condition determining module 10, a power saving module 12, and a loop processing module 14. The structure is described in detail below.

Based on the terminal power saving device introduced in the above embodiment, in the actual operation, the smart phone is taken as an example to introduce a smart phone power saving system, and FIG. 3 is a smart phone power saving system according to an embodiment of the present invention. Schematic diagram of the structure, as shown in Figure 3, the smart phone power saving system includes: long distance Proximity sensor, time and power saving policy setting unit, main processor, power management chip, mobile phone power supply.

The time and power saving strategy setting unit and the proximity sensor are respectively connected to the main processor, and the output of the main processor is connected to the power management chip, and the power management chip is connected to the mobile phone power supply. The following are introduced separately.

1) The time and power saving policy setting unit is set to set the no-interaction waiting time for the large power consumption application, and set the power saving strategy to be used when the power saving condition is satisfied. A specific embodiment of the time setting of the time and power saving policy setting unit is: 2 minutes, 3 minutes, 5 minutes, 10 minutes are displayed on the UI (User Interface), and the specific value can be selected by the user, preferably, The default value is 2 minutes. A specific embodiment of the power saving strategy is: the display on the UI turns off the LCD and the touch screen, and / or, the system goes to sleep, preferably, the default system goes to sleep.

2) The long-distance proximity sensor has a function similar to that of the second detecting unit in the terminal power-saving device of the above embodiment, and is used for detecting the presence or absence of a user in front of the LCD. The long-distance proximity sensor is mounted on the surface of the phone and the detection distance is farther than the proximity sensor on the existing smartphone. According to the experience, the user is 10~50cm away from the LCD when using photos such as taking pictures, taking pictures, watching videos, etc. Therefore, the maximum detection distance of the long distance proximity sensor generally needs to reach 40cm~50cm.

After installing this long-distance proximity sensor, the mobile short-range sensor can retain or remove two specific embodiments. In the embodiment of the existing short-distance proximity sensor, the two proximity sensors are responsible for each other, and the short-distance proximity sensor continues to perform the action of detecting and approaching the human body when the original call is made, and the threshold register only retains a set of 4cm, 5cm. Response. The long-distance proximity sensor performs the detection of the presence or absence of a user in front of the LCD as described in the present invention. The response distance can be set to 10 to 50 cm, and only a set of 10 cm and 50 cm response values are reserved in the threshold register.

In the embodiment of removing the short-distance sensor, two sets of upper and lower limits are set in the threshold register of the long-distance proximity sensor: the first set of thresholds realizes a detection distance of about 5 cm for detecting proximity to the human body during a call, that is, a response value of 4 cm and 5 cm. , called only when the user calls the application scenario; the second set of threshold implementations The detection distance is about 10~50cm. It is used to detect close to the human body when it is used for large power consumption, that is, the response value of 10cm and 50cm. It is called when it is applied to a large power consumption other than the user's call application. The latter embodiment can simultaneously implement the original function and the new function of the present invention, and the upgrade cost is lower, which is a preferred embodiment of the present invention.

3) The main processor has a function similar to that of the condition judging module and the power saving module in the terminal power saving device in the above embodiment, and is used for judging whether the mobile phone conforms to the power saving strategy, and controlling the power management chip to implement the power saving strategy. In the high power application scenario, when the set time T of the time and power saving policy setting unit is reached, the main processor controls the long distance proximity sensor to turn on the detection, and transmits the detection result to the main processor, and no user exists in front of the LCD. The main processor controls the power management chip to execute the power saving policy set by the user. No user exists in front of the LCD, and the main processor controls the time setting unit to re-time.

4) The power management chip is set to manage and control the power of the mobile phone. The power management chip can control the power on and off of each module of the mobile phone. In the high power application scenario, when the set time T of the time and power saving policy setting unit is reached, and no user exists in front of the LCD, the power management chip accepts the master. The processor controls the execution of the power saving policy set by the user.

5) Mobile phone power supply, used for power supply of all modules of the whole machine and mobile phone. Accept the control of the power management chip, turn on and off the power supply of each module or the whole machine of the mobile phone.

The embodiment of the invention further provides a computer program, comprising program instructions, when the program instruction is executed by the terminal, so that the terminal can execute the above method.
