Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Basic thought of the present invention is: the present invention comes the portable terminal control of economizing on electricity by software, the energy-saving mode task adopts the operation of lowest priority task inquiry mode, being responsible for when appropriate, machine makes portable terminal enter energy-saving mode (Battery Save, BS), to reduce standby current, reach the purpose of prolongs standby time.Withdraw from the energy-saving mode task and then move, when particular event takes place, be responsible for portable terminal is withdrawed from energy-saving mode, to guarantee the realization of each normal function of terminal in the function call mode.
Fig. 1 shows the structure of the electricity-saving control system of portable terminal of the present invention, and this electricity-saving control system 10 is applied in the portable terminals such as mobile phone, PHS, and it comprises energy-saving mode task module 11 at least and withdraw from energy-saving mode module 12, wherein:
Described energy-saving mode task module 11 is used for the operation of lowest priority task inquiry mode, and responsible portable terminal enters the operation of energy-saving mode; When inquiring when satisfying the economize on electricity condition, make this portable terminal enter energy-saving mode.Described energy-saving mode task module 11 runs on the backstage of whole mobile terminal system, and calls each other with each hardware driving, task of timer and/or the protocol stack of described portable terminal, can carry out direct control to hardware simultaneously.The running status of the whole portable terminal of described energy-saving mode task module 11 monitoring is responsible for making portable terminal enter energy-saving mode on suitable opportunity, to reduce standby current, reaches the purpose of prolongs standby time.Importantly, utilize the characteristic of operating system in the portable terminal,, illustrate that other tasks all are idle, therefore can enter energy-saving mode when taking turns to when carrying out as the energy-saving mode task of lowest priority task.
The described energy-saving mode module 12 that withdraws from is used for moving in the function call mode, satisfies when withdrawing from the economize on electricity condition when inquiring, and particular events such as button, the broadcast of bell sound for example take place, and this portable terminal is withdrawed from energy-saving mode.Described each hardware driving, task of timer and/or the protocol stack that withdraws from energy-saving mode module 12 and described portable terminal calls each other, and the hardware driving here includes but not limited to keyboard drive, accessory drive, bell sound broadcast driving etc.Withdraw from energy-saving mode module 12 and can be used to be controlled at and in time withdraw from after being strayed into energy-saving mode, also can in the energy-saving mode task, also can call energy-saving mode and withdraw from task.Described withdraw from energy-saving mode module 12 portable terminal withdrawed from energy-saving mode rapidly after, can guarantee the realization of the various normal functions of terminal.
In addition, for guaranteeing the stability of whole mobile terminal system, the present invention preferably adopts Controlled CPU (central processing unit) operational mode to economize on electricity, and the switching of controlling primary/secondary clock realizes the switch of energy-saving mode, reaches the purpose of stand-by energy-saving.Energy-saving mode of the present invention preferably adopts the cpu clock source is switched to auxilliary clock from master clock, closes the crystal oscillating circuit of master clock simultaneously.Like this, after portable terminal entered energy-saving mode, CPU will slowly operation under auxilliary clock, and all with master clock as the peripheral circuit in clock source all with out of service.The energy-saving mode that withdraws from of the present invention preferably adopts the cpu clock source is switched to master clock from auxilliary clock, and the crystal oscillating circuit with described master clock reopens simultaneously, so that recover normal condition.
