Detailed ways

In the present invention, a general power consumption control module is designed, a device linkage database is set to store the linkage relationship of each device, and the equipment linkage database is called by the power consumption control module to achieve the purpose of controlling the power consumption of the equipment.

As shown in Figure 1, the mobile terminal power consumption control system provided by the present invention includes an application module 1, a power consumption control module 2 and a device linkage database 3; the device linkage database 3 is stored on the storage medium of the mobile terminal, such as FLASH etc.; the device linkage database 3 stores the equipment linkage relationships of all devices of the mobile terminal.

The application module 1 outputs device events, such as turning on the camera, backlight timeout, opening of the mobile phone cover, etc., to the power consumption control module 2; the power consumption control module 2 adjusts the self-function of the device according to the device event. power consumption, and access the device linkage database 3 through the drive interface of the mobile medium to obtain the device linkage relationship of the device event; the power consumption control module 2 calls the device driver interface according to the obtained device linkage relationship. Device 4 performs power consumption control.

As shown in Figure 2, wherein the power consumption control module 2 includes an event judgment module 21, a linkage relationship calling module 22 and a control module 23;

The event judging module 21 receives a device event from the application module 1, and judges whether the device is a device with a processed linkage relationship;

The linkage relationship calling module 22 accesses the equipment linkage database 3 through the drive interface of the mobile medium according to the equipment event, and obtains the equipment linkage relationship of the equipment event;

The control module 23 adjusts the power consumption of the device itself, and controls the power consumption of other devices 4 involved in the device linkage relationship by calling a device driver interface according to the device linkage relationship.

Among them, the device linkage database 3 can be set differently according to different mobile terminals, such as the device linkage relationship between the devices shown in the following table. These device events include device events related to power consumption, such as up and down Power, digital signal processor operating frequency adjustment, etc., also includes device events that have nothing to do with power consumption, such as opening and closing the flip of a mobile phone, but these device events that have nothing to do with power consumption have a device linkage relationship with other devices. Can cause changes in power consumption of other devices.

When developing different mobile terminals, according to which devices the mobile terminal has and the common device events of the mobile terminal, the device linkage relationship of each device of the mobile terminal is set in the device linkage database 3, such as shown in the following table The device event of closing the LCD screen of the mobile phone has a device linkage relationship with some other devices, such as powering off the LCD screen, powering off the backlight, and powering off the camera. Digital signal processors stop working, etc.

At the same time, the device linkage relationship of some device events involving other devices will also cause changes in the power consumption of other devices. For example, as shown in the table below, the power-off event of device 1 will cause the power adjustment of device 2 and the power-off of device 3 , the power-off event of device 3 will reduce the operating frequency of device 4, etc., so the linkage relationship of one device will cause the linkage relationship of another device, forming a linkage relationship cycle.

As shown in Figure 3, the present invention also provides a method for controlling power consumption of a mobile terminal, comprising the following steps:

S301: The application module sends the device event to the event judgment module of the power consumption control module;

S302: The event judging module receives the device event, and judges whether the device of the device event is a processed linkage related device, if so, execute step S308, otherwise, execute step S303;

S303: The linkage relationship calling module marks the device as the equipment with the linkage relationship processed;

In step S303, the linkage relationship calling module marks the device as a processed linkage relationship. The purpose is that the equipment linkage relationship of each device recorded in the equipment linkage database may cause an endless loop of equipment linkage, as shown in the following table. Powering off device 1 causes device 3 to power off, device 3 powers off causing device 5 to power off, device 5 powering off causes device 1 to power off, thus forming an endless loop in the actual implementation. When the event judging module receives a device event from the application module, it first judges whether the device is a device with a linkage relationship that has been processed, and if so, stops processing the power consumption control of the device; The device is marked as the device that has processed the linkage relationship, which avoids the disadvantage of crashing when there is an infinite loop in the equipment linkage relationship of each device in the equipment linkage database.

S304: The control module adjusts the power consumption of the device itself;

S305: The linkage relationship calling module calls the equipment linkage database through the drive interface of the storage medium, and obtains the equipment linkage relationship of the equipment event;

S306: The linkage relationship calling module judges whether the other equipment involved in the equipment linkage relationship also causes the power consumption change of some other equipment. If step S302 is executed, it is judged one by one whether the other equipment is the equipment that has processed the linkage relationship. , otherwise execute step S307;

S307: The control module receives the device linkage relationship of the device event from the linkage relationship calling module, and calls a device driver interface to control power consumption of other devices involved in the device event according to the device linkage relationship;

S308: Stop the power consumption control of the device event.
