Brought forward is stated, and controller 34 is respectively coupled to battery 22, mains switch 24 and latch 32, and is used for detecting connection status and the electric weight of battery 22, and also can receive the switching on and shutting down signal that mains switch 24 sends.Controller 34 according to above-mentioned data can be suitable unlatching or close latch 32, make latch 32 can send further signal to control switch 12, the power supply that is provided to control power circuit 14.Controller 34 is for example the embedded controller that is built within portable electronic devices 20, and does not limit its scope.The situation such as whether insert with next on-off state for portable electronic devices 20 and battery 22, each is further described for an embodiment.
Power control method flow chart when Fig. 3 is the shutdown that illustrates according to preferred embodiment of the present invention please refer to Fig. 3.Please be simultaneously with reference to Fig. 1 and Fig. 3, the present embodiment supposes that portable electronic devices 20 is to be in open state at the beginning, that is to say that control switch 12 is in the state of conducting, offer portable electronic devices 20 and by power supply conversion electrical equipment 10, alternating voltage is converted to direct voltage.
When the user shut down action (for example press mains switch 24 or select shutdown in viewing window pictures) to portable electronic devices 20, controller 34 can receive shutdown signal (step S301).Then carry out step S302, whether have battery 22 to be connected to portable electronic devices 20 by controller 34 detectings.If portable electronic devices 20 is equipped with battery 22, whether execution in step S303 detecting battery 22 electric weight reach reference value; Otherwise, if portable electronic devices 20 is not equipped with battery 22, skip to step S305, close latch 32 with closing control switch 12 by controller 34, and blocking-up power circuit 14 provides power supply to portable electronic devices 20.
Brought forward is stated, when whether execution in step S303 detecting battery 22 electric weight reach reference value, if the electric weight of the battery 22 of portable electronic devices 20 reaches saturation condition, close latch 32 with closing control switch 12 by controller 34, and blocking-up power circuit 14 provides power supply to portable electronic devices 20 (step S305); Otherwise, if the electric weight of battery 22 does not reach saturation condition, start latch 32 with unlatching control switch 12 by controller 34, and provide power supply to battery 22 chargings (step S304) by power circuit 14.In other words, whether the spirit of the present embodiment namely when portable electronic devices 20 shutdown, is differentiated battery 22 by controller 34 and is charged complete.When battery 22 charging is complete, power supply changeover device 10 is closed, so can avoid power supply changeover device 10 to cause extra power consumption because continuing running, more can avoid portable electronic devices 20 to be subjected to electricity to cause overheated or to cause the situations such as 22 life-spans of battery shorten because continuing.
In the present embodiment, if after portable electronic devices 20 shutdown, when the user just packs battery 22 within portable electronic devices 20,34 of latchs can be started by the electric power of battery 22, and then open control switch 12, and provide power supply to portable electronic devices 20 by power circuit 14.Then carry out as above-mentioned S303
-The step of S305, whether the electric weight that continues detecting battery 22 reaches reference value, and opens and closes according to this control switch 12, controls the power supply that power circuit 14 offers portable electronic devices 20.Thus, portable electronic devices 20 still can charge to other battery 22 when off-mode, and when battery 22 charging is complete the running of powered-down transducer 10 to save power consumption.
Except above-mentioned shutdown action, the present invention also is included in when receiving the start signal, automatically opens control switch 12 to provide power supply to portable electronic devices 20, and implementation step is as follows.Fig. 4 is the flow chart of steps that receives the power control method of start during signal that illustrates according to preferred embodiment of the present invention, please refer to Fig. 4.The process that the present embodiment explanation portable electronic devices 20 is started shooting from off-mode, wherein when the user pressed mains switch 24,24 of mains switches can be sent the start signal to controller 34.And controller 34 will start latch 32 to open (conducting) control switch 12 (step S402) after receiving this start signal (step S401).This moment, power supply changeover device 10 namely can be returned to normal operation, and provided power supply to controller 34 and portable electronic devices 20 (step S403).When portable electronic devices 20 was started shooting under off-mode, power supply changeover device 10 also can and then be waken up thus, and did not need the user in addition manually with the switch opens of power supply changeover device 10, and is more convenient for the user.
In sum, power control system of the present invention and method have following several advantages at least:
1, the connection status of Auto-Sensing switching on and shutting down signal and battery and electric weight to control the running of power supply changeover device, do not need again by user's hand switch power supply changeover device, tool ease of use.
2, according to the electric weight size of battery, provide charging current in good time, and when the battery full charging, the powered-down transducer, therefore can reduce the power consumption of power supply changeover device, more avoid portable electronic devices or battery because continuing to be subjected to electricity, cause overheated and cause its life-span to shorten.
3, still can insert battery under off-mode and charge, and in good time powered-down transducer, power consumption avoided.
the above, it is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, although the present invention discloses as above with preferred embodiment, yet be not to limit the present invention, any those skilled in the art, within not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solution of the present invention, any simple modification that foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
