Below in conjunction with Fig. 3, one embodiment of the present of invention are described.
Generally, mobile phone can enter in the selection according to the user different mode of operations.The mode of operation here is divided into pattern and the cell voltage low-voltage special pattern during lower than normal voltage of cell voltage when normal.The normal voltage electric weight of different working modes when having to(for) battery is not discussed in the present embodiment.Need at present additionally add a kind of pattern on mobile phone in the present embodiment, make mobile phone in dead battery and can be with this work pattern after automatic shutdown, this mode of operation can be referred to as ultralow electric weight mode of operation.This pattern is that the user generally can not use, and only has in case of emergency and just uses.For whether using this pattern, the user can freely select, such as, the user presses Macintosh and jumps out the model selection menu from screen when start, and the user independently selects according to situation.
In this ultralow electric weight mode of operation, the last electric weight of battery is few, such as less than 7%, according to the discharge curve of battery, battery is along with the release of electric current at this moment, and its output voltage will speed up decline, that is to say, the time that can use is not long, and the electric current that can obtain is also little.Fig. 3 shows the discharge curve schematic diagram of battery.
In Fig. 3, measured data is that battery electric quantity also is left 61mah (MAH) when cell voltage 3.319V.Therefore, in the situation that this light current amount, just must cut out to reduce power consumption to what the cell-phone function under normal mode of operation carried out quite large degree as far as possible, otherwise with cisco unity malfunction.
The below is respectively for only using mobile phone to search the application of address list content and only use mobile phone to carry out the application that the short time communicates by letter to describe.
1) only use mobile phone to search the application of address list content
At first the type of device that adopts for terminal, minimum operating voltage is lowered near chip limit place (take the platform of certain company as example, the minimum 3.0V of being input as that its PM power management chip can be accepted, adopting the shutdown voltage that arranges under the terminal normal running conditions of this chip is 3.3V～3.4V, and namely can be lowered to 3.0V with shutdown voltage this moment).Simultaneously, on hardware except primary processor and memory, display and keyboard reservation work, other are such as radio-frequency front-end, multi-media module, all kinds of Peripheral Interface, even on host processor chip without GPIO port etc., can not power fully, simultaneously to supporting the processor of AFC (automatic frequency control) and AVC (automatism voltage control) technology, the operating frequency of CPU and operating voltage all can also be adjusted to can support current application minimum situation further to reduce current drain.For display screen larger in power consumption, can suitably reduce its backlight intensity, can further reduce again the electric current of tens milliamperes.On the mobile phone terminal of processing more than doing, the inventor does overtesting, when the capacity cell voltage that is 830Mah (MAH) is 3.1V, the action of normal boot-strap inquiry address list only expends the electric current of 50～100mA, and this moment, battery still had the capacity of 15mah left and right apart from the 3.0V of shutdown voltage, electric current with 100ma comes dynamic duty, can support more than 9 minutes.This is rough estimation, and reality is tested to such an extent that result is, reaches more than 3 minutes.Can complete the function of searching address list fully.
2) use mobile phone to carry out the application of short time communication
This class is used and must be supported communication function, allows the user finish important language the short time or sends one or two important short message etc.If need to communicate, just need in front 1) in the pattern basis on, make radio-frequency module carry out work.This will cause the increase of current sinking.At first with maximum power (take the GSM network as example, will reach 33dbm, namely 2 watts) emission, will cause the large electric current of moment and voltage will be moved to very low this moment for the action of particularly starting shooting and looking for net, mobile phone.
In order to tackle this situation, need to adopt some measures, such as, revise the power control strategy, not with maximum power transmission.General's minimum shutdown voltage at this moment past downward more simultaneously (such as, the overdischarge voltage of the PTC charge-discharge circuit of general battery of mobile phone is arranged between 2～3V, take 2.5V as example, can look the concrete condition voltage that will shut down and be adjusted downward to 2.6～2.8V), the shutdown that causes with the lower fluctuation of dealing with transient voltage.After taking above measure, use mobile phone communication, when the capacity cell voltage that is 830Mah (MAH) is 3.21V, put through the GSM phone, conversation has continued automatic shutdown after 13 seconds, in 13 seconds, the user be enough to complete such as cry for help, explain, inform, the communication of the brief important information such as designated time place.This moment, cell voltage dropped to 2.8V, and then voltage is in slow rise after overdischarge in short-term, and the electric weight that waits for a period of time can recover to some extent.
For different batteries, different discharge curves is arranged, concrete data just have a little difference.
Extra low voltage mode of operation in the present embodiment does not encourage the user often to use, circuit working is connecing near-critical place after all, and work long hours and also can bring the battery over-discharge can and problem that capacity reduces gradually, producer should be in the instruction manual book clear and definite prompting point out to use the pros and cons of emergency mode.Suggestion producer arranges Macintosh start, allows the emergency mode be transparent to the user under normal circumstances, does not affect its normal use fully.The operating position of this extra low voltage pattern need to clearly be informed by producer in specification, the user can in case of emergency can be accomplished something, and separates its matter of great urgency.
Below in conjunction with Fig. 4, an alternative embodiment of the invention is described.
This embodiment is take the WCDMA/GSM/GPRS multimode mobile phone platform MSM6280 of Qualcomm (QualCom company) as example.Suppose that mobile phone has been under the state of low electric weight.
With reference to Fig. 4, the method for this embodiment comprises the following steps:
Step S402 arranges the Macintosh start.A key+B key+C key is set in the present embodiment starts shooting, doing like this is frequently to enter Low Power Mode in order to prevent user misoperation.
Whether step S404 when mobile terminal is used in judgement, needs to start communication function, if so, and execution in step S406, otherwise execution in step S412.
Step S406 in the situation that needs start communication function, carries out hardware initialization, mobile terminal is started enter main task, and lower shutdown voltage, and the voltage that for example shuts down is set to 2.6V.
Step S408, the initiating hardware module, the power supply of reserve storage, LCD port, keyboard interface, radio-frequency module, and stop being power supplies (but keeping receiver (receiver) module) such as T card expansion mouth, audio frequency power amplifier codec.
Step S410 starts and looks for network service, with looking for the maximum transmission power in the net strategy suitably to reduce, for example is reduced to 20dB by 33dB, then starts user's operations such as cards folder initialization task, standby.
Step S412 carries out hardware initialization, mobile terminal is started enter main task, and lower shutdown voltage, and the voltage that for example shuts down is set to 3.0V.
Step S414, the initiating hardware module, the power supply of reserve storage, LCD port, keyboard interface, and stop being power supplies such as T card expansion mouth, audio frequency power amplifier codec, radio-frequency module.
Step S416, the read-write task of startup memory directly enters idle process after cards folder initialization success, simultaneously display brightness is turned down one or two grades, and standby is to wait for user's input.
Enumerated in an embodiment two kinds of possible demands, namely do not communicated and do not need to communicate, but also other demand might be arranged.Under above-mentioned two kinds of application models, thorough some PORT COM of power down on hardware, such as no GPIO mouth, part memory etc. even, and turn down backlight intensity and further lower current drain.
In this embodiment, can according to the size of operand, adjust operating frequency and the operating voltage of CPU.For example, if CPU supports AVC (automatism voltage control), AFC (automatic frequency control), can use simultaneously AVC (automatism voltage control), AFC (automatic frequency control) technology to control the power consumption of CPU.
The invention enables the user in the situation that mobile phone due to electric weight not and can not normal boot-strap, successfully the short time is used the partial function of mobile phone, as short time conversation, one or two note, address list in mobile phone etc. is searched in start, has satisfied user's needs.
