Embodiment
Fig. 1 is the process flow diagram of method for managing power supply of signal one embodiment of the invention, and Fig. 2 is the calcspar of portable electric device that is applied to the method for managing power supply of Fig. 1.The method for managing power supply of Fig. 1 for example is applicable to the portable electric device 100 of Fig. 2.Please refer to Fig. 2, portable electric device 100 comprises a processing unit 110, a switch 120 and a battery 130.Processing unit 110 is coupled to switch 120, carries out switching on and shutting down with the push button signalling according to switch 120.Battery 130 is coupled to processing unit 110, gives processing unit 110 with power supply.In the present embodiment, portable electric device 100 for example is a mobile phone, but in the embodiment that another does not illustrate, portable electric device 100 also can be personal digital assistant, palmtop computer or the like.Explanation for ease below will cooperate the portable electric device 100 of Fig. 2 that the flow process of the method for managing power supply of Fig. 1 is described, but not as limit.
Please refer to Fig. 1 and Fig. 2, method for managing power supply comprises the following steps.At first carry out step S110, the user utilizes 120 pairs of portable electric device starts of switch.Then carry out step S120, processing unit 110 reads the electric weight of the battery 130 of portable electric device 100.Carry out step S130 then, whether processing unit 110 judges the electric weight of battery 130 smaller or equal to an Emergency Power setting value, and wherein the Emergency Power setting value is greater than a system closedown setting value of portable electric device 100.The electric weight of judging batteries 130 when processing unit 110 carries out step S140 during smaller or equal to the Emergency Power setting value, and processing unit 110 makes portable electric device 100 shutdown.
In the present embodiment, if the electric weight of battery 130 drops to the system closedown setting value when following, just portable electric device 100 possibly can't be started shooting.But owing to portable electric device 100 just shuts down when the Emergency Power setting value is following, and the Emergency Power setting value is again greater than the system closedown setting value.Therefore, portable electric device 100 carries out Help by Phone or when calling, the dump energy between Emergency Power setting value also capable of using and the system closedown setting value uses portable electric device 100, and is quite convenient when the user is badly in need of temporarily.
Fig. 3 is the process flow diagram of the method for managing power supply of signal another embodiment of the present invention.Please refer to Fig. 2 and Fig. 3, explanation for ease below will cooperate the portable electric device 100 of Fig. 2 that the flow process of the method for managing power supply of Fig. 3 is described, but not also as limit.
At first carry out step S210, the user utilizes 120 pairs of portable electric device starts of switch.Then carry out step S220, processing unit 110 reads the electric weight of the battery 130 of portable electric device 100.Carry out step S230 then, whether processing unit 110 judges the electric weight of battery 130 smaller or equal to an Emergency Power setting value, and wherein the Emergency Power setting value is greater than a system closedown setting value of portable electric device 100.The electric weight of judging batteries 130 when processing unit 110 carries out step S240 during smaller or equal to the Emergency Power setting value, and processing unit 110 judges that whether the electric weight of battery 130 is smaller or equal to the system closedown setting value.The electric weight of judging batteries 130 when processing unit 110 carries out step S250 during smaller or equal to the system closedown setting value, and processing unit 110 makes portable electric device 100 shutdown.Relatively, the electric weight of judging batteries 130 when processing unit 110 carries out step S260 during greater than the system closedown setting value, and processing unit 110 can make portable electric device 100 shutdown equally.Then carry out step S270, launch an Emergency Power pattern, so that portable electric device is started shooting and made portable electric device keep the state of start.
In the present embodiment, step S270 can comprise the following steps.At first, a programmable button signal of processing unit 110 receiving keys 120.Then, processing unit 110 makes portable electric device 100 starts and makes portable electric device 100 keep the state of start according to the programmable button signal.For instance, the programmable button signal for example can according to continuous push switch 1,200 seconds produce.That is to say that user's push switch continuously carried out general start (step S210) in 120 3 seconds, and utilized 1,200 seconds mode of continuous push switch to get into the Emergency Power pattern.In the embodiment that another does not illustrate, different switch also capable of using or button come to trigger respectively general start and Emergency Power pattern.
After step S270, also can carry out step S280, processing unit 110 receives an off signal of switch 120 or a charging signals of an external power supply (not illustrating).Then carry out step S290,, finish the Emergency Power pattern according to off signal or charging signals.In addition, in the present embodiment, under the Emergency Power pattern, more can carry out the following step.At first, processing unit 110 reads the electric weight of battery 130.Then, processing unit 110 judge battery 130 electric weight whether smaller or equal to the system closedown setting value.When the electric weight of battery 130 during, finish the Emergency Power pattern and also make portable electric device 100 shutdown smaller or equal to the system closedown setting value.
Further, portable electric device 100 also can provide user's interface, in order to receive user instruction, with the size of decision Emergency Power setting value.For example, the user can carry out the setting program of portable electric device 100, sets the Emergency Power setting value and can provide in the setting program like 10%, 0%, 20% option to the user.Whereby, can let the user decide in its sole discretion will to reserve how many electric weight and supply urgent use.
In sum, the present invention is by letting portable electric device when the Emergency Power setting value is following, just shut down, and the Emergency Power setting value is again greater than the system closedown setting value.Therefore, portable electric device carries out Help by Phone or when calling, the dump energy between Emergency Power setting value also capable of using and the system closedown setting value uses portable electric device, and is quite convenient when the user is badly in need of temporarily.Thus, can the person of avoiding the use of being badly in need of portable electric device but runs into the awkward situation that does not have electricity and produces.
Though the present invention discloses as above with preferred embodiment; Right its is not that any those skilled in the art are not breaking away from the spirit and scope of the present invention in order to qualification the present invention; When can doing a little modification and perfect, so protection scope of the present invention is when being as the criterion with what claims defined.
