Abstract
The invention discloses a power supply method for a wireless communication terminal. The power supply method for the wireless communication terminal comprises the following steps: when the wireless communication terminal is in a state that only an RAM (Random Access Memory) and a clock unit are powered, whether a main battery is in connection or not is judged, and the main battery is used for power supply if the main battery is in connection, and whether the electric quantity of a backup battery is more than a preset value or not is judged if the main battery is not in connection; the backup battery is used for power supply if the electric quantity of the backup battery is more than the preset value, and the backup battery stops supplying power to the RAM and only supplies power to the clock unit if the electric quantity of the backup battery is not more than the preset value; when the backup battery supplies power, whether the main battery is restored to be in connection or not is judged, the main battery is used for power supply if the main battery is restored to be in connection, and the backup battery continuously supplies power if the main battery is not restored to be in connection; and when the wireless communication terminal is started up, whether the main battery is in connection or not is judged, the wireless communication terminal is not started up if the main battery is not in connection, whether the main battery supplies power to the RAM or not is judged if the main battery is in connection, the wireless communication terminal is rapidly started up if the main battery supplies power to the RAM, and the wireless communication terminal is normally started up if the main battery does not supply power to the RAM. With the adoption of the technical scheme adopted by the invention, the wireless communication terminal can be continuously powered under the condition that the wireless communication terminal is close to shutdown.
Description
Technical field
The present invention relates to the wireless communication terminal technical field, relate in particular to a kind of wireless communication terminal method of supplying power to.
Background technology
Along with the popularization of intelligent wireless communication terminal, the function at terminal becomes increasingly complex, and the thing that do is more and more, so cause the speed of starting up of terminal more and more slower.
In order to improve the starting up speed at terminal; Present modal way is to carry out snapshot to system, is kept at then among the nand flash, recovers on-the-spot when start shooting next time; When being system closedown random asccess memory (Random Access Memory; RAM) reflection is saved among the nand flash, in the time of system boot, recovers RAM.
Also have a kind of mode, can get into sleep state when system is no at ordinary times, under this state, CPU gets into the idle state, and the frequency vanishing is in some system even can will be zero with CPU voltage; All ancillary equipment get into holding state, and power consumption is few; The Baseband processor is still in work, owing to will accept phone and short message; RAM keeps content; The different system of complete machine power consumption this moment is different, and representative value is 2-5mA; This recovering state is that the normal condition time is very fast, only need recover CPU and get final product, and the time probably is in one second.
But both of these case all requires wireless communication terminal to keep power supply state always, in case after battery did not have electricity or accidental, the content of RAM just all disappeared, just needs the very long available machine time when starting shooting again, reaches about 1 minute.
Summary of the invention
The objective of the invention is to propose a kind of wireless communication terminal method of supplying power to, near under the off-mode, can continue to supply power to wireless communication terminal at wireless communication terminal.
A kind of wireless communication terminal method of supplying power to may further comprise the steps:
A, main battery and reserve battery are set;
When B, wireless communication terminal pulled out main battery under open state, wireless communication terminal got into off-mode, and main battery and reserve battery are not supplied power;
C, wireless communication terminal only get into when the state of RAM and clock unit power supply, judge whether main battery is communicated with, if be communicated with, then by main battery to RAM and clock unit power supply, and go to step F, if there is not connection, then go to step D;
D, whether judge the reserve battery electric weight greater than a preset value, if, by reserve battery to RAM and clock unit power supply; And go to step e, if this moment, wireless communication terminal started start, then go to step H; If not; Then reserve battery stops the power supply to RAM, only to the clock unit power supply, and goes to step G;
When E, reserve battery power supply, judge whether main battery recovers to be communicated with,, then supply power to RAM and clock unit, and go to step F,, then go to step D if be not communicated with by main battery if be communicated with;
F, wireless communication terminal start start, and wireless communication terminal is realized quick turn-on;
G, wireless communication terminal start start, judge whether main battery is communicated with, if then normal boot-strap if deny, then goes to step H;
H, wireless communication terminal are not started shooting.
Reserve battery is the battery of 200uAh.
Further comprising the steps of:
When main battery was communicated with, reserve battery charged.
Among the step D, said preset value is 30% of the whole electric weight of reserve battery.
Adopted technical scheme of the present invention, near under the off-mode,, also can continue to supply power to wireless communication terminal even the situation that battery electric quantity exhausts or battery takes out occurs at wireless communication terminal.
Description of drawings
Fig. 1 is the flow chart of wireless communication terminal power supply in the specific embodiment of the invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Fig. 1 is the flow chart of wireless communication terminal power supply in the specific embodiment of the invention.As shown in Figure 1, this flow process may further comprise the steps:
Whether step 104, continuation judge the reserve battery electric weight greater than a preset value, such as 30% of the whole electric weight of reserve battery, if then go to step 105, if not, then go to step 109.
In above process, when main battery was communicated with, reserve battery charged.When main battery can't be supplied power for a certain reason, reserve battery also can be supplied power to RAM in a period of time, thereby had guaranteed that the user still can realize closing fast start when main battery can't be supplied power.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
