Abstract
The utility model discloses an intelligent mobile phone power management module, which comprise a PM Daemon module, a PM Component module and a power management chip, wherein the PM Daemon module and the PM Component module are connected; the PM Daemon module controls and dispatches the PM Component module after receiving an upper layer application program; simultaneously, the PM Component module provides a hardware control interface for the PM Daemon module; the PM Component module is also connected with the power management chip so as to control and manage the PM Component module. The power management module prolongs the standby time, and the average standby time can be prolonged by 23 percent; moreover, the sleep current of the whole machine system can be reduced to 1mA; and the multi-media application and the conversation function time of mobile phones can also be prolonged by 20 percent.
Description
Technical field
The utility model belongs to embedded mobile terminal equipment, particularly a kind of smart mobile phone power management module.
Background technology
Along with development of science and technology, human life is the dependence science and technology of the degree of depth more and more, because there is demand in the modern to portable electronics, so portable development in science and technology is quite rapid.Smart mobile phone is as a kind of common portable electronics, it is used more and more widely, smart mobile phone has a variety of functions, except traditional call function, can also realize playing the function of computers such as audio frequency, video file, online, in fact present smart mobile phone is exactly a small-sized computer.But smart mobile phone is full of the electricity back and is 1000mAh if only converse, and average energy was with 200 to 300 minutes; If use the multimedia related application, displaying video for example, battery only can be with 120 to 240 minutes.Smart mobile phone need carry the application more than many times of regular handsets, and its task amount approaches the task amount of computer, and therefore power management software and algorithm thereof use the time of smart mobile phone that very important meaning is arranged to prolonging the terminal use efficiently.
There is multiple electricity saving method to be used to save electric power or extending battery life, comprises the monitoring time out, enter sleep state etc.In some treatment system, people often adjust operational clock frequency or built-in function voltage; Sometimes also reduce the exploitation speed of central processing unit.
In a word, existing cellular phone power supplies management mode can not satisfy the requirement of mobile phone.
The utility model content
The technical problem that the utility model solved is to provide a kind of smart mobile phone power management module that can prolongs standby time.
The technical solution that realizes the utility model purpose is: a kind of smart mobile phone power management module, comprise PM Daemon module, PM Component module and power management chip, PM Daemon module is connected with the PMComponent module, after PM Daemon module receives upper level applications, the PMComponent module is controlled and dispatched, and PM Component module provides the hardware controls interface for PM Daemon module simultaneously; PM Component module also is connected with power management chip, and it is carried out control and management.
The utility model compared with prior art, its remarkable advantage: 1) prolonged stand-by time, can prolong average stand-by time 23%; 2) can reduce the machine system quiescent current to 1mA; 3) prolong service time of mobile phone, can prolong multimedia application and mobile phone communication function time 20%.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Accompanying drawing is a kind of smart mobile phone power management module schematic diagram of the present utility model.
Embodiment
In conjunction with the accompanying drawings, a kind of smart mobile phone power management module of the present utility model, comprise PM Daemon module, PM Component module and power management chip, PM Daemon module is connected with PM Component module, after PM Daemon module receives upper level applications, PM Component module is controlled and dispatched, and PM Component module provides the hardware controls interface for PM Daemon module simultaneously; PM Component module also is connected with power management chip, and it is carried out control and management, thereby finish the power supply of processor and ancillary equipment is controlled, and reaches the target of economize on electricity.
The algorithm that the utility model uses has following Core Feature:
A, based on the multi-core CPU load evaluation engine of Co-Profiler;
B, the crucial application of multinuclear, the real-time CPU energy consumption of multizone system parser;
The dynamic and intelligent management of power use QoS power supply decision engine of C, the pressure regulation of multinuclear self-adapting frequency modulation.
Because the real-time load of system uses an administrative decision engine self adaptation to regulate the voltage or the frequency of processor and system's periphery peripheral hardware thereof by intelligence, the selection rising of intelligence or the voltage to frequency of reduction processor have reached the balance between performance and the save power.
Power management chip carries out concrete management and control to power supply, utilize this module that smart mobile phone is controlled, can prolong the useful life of battery of mobile phone, make stand-by time prolong 23%, and can prolong multimedia application and mobile phone communication function time 20%.Satisfied the demand of people greatly to intelligent mobile phone battery.
