Embodiment
The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
The present invention is directed to data wire and carry out PC when being connected with terminal, need to distinguish charging and transfer of data/synchronous different situations, a kind of intelligent charging method of terminal is proposed, its core concept is: when terminal is connected on the PC by data wire, terminal is gathered the current battery voltage value in real time, and battery voltage value of gathering and the battery pre-charging voltage threshold of being scheduled to are compared; According to comparative result, when the battery voltage value of gathering was not higher than the battery pre-charging voltage threshold, terminal entered charging and transfer of data/synchronous regime simultaneously, otherwise terminal only enters transfer of data/synchronous regime.
Need to prove, when the so-called terminal of the present invention is meant and is connected with PC by data wire, can realize charging and all terminals of transfer of data/synchronizing function, this terminal is not limited only to smart mobile phone, personal digital assistant (PDA, Personal Digital Assistant), also comprise music players such as MP3, MP4.In a word, everyly can connect realize charging and transfer of data/synchronizing function terminal, all be applicable to intelligent charging method of the present invention, all should belong in the terminal scope that the present invention will protect by data wire.
In addition, because the realization charging commonly used at present and the data wire of transfer of data/synchronizing function are the usb data line, therefore, data wire of the present invention certainly is the usb data line; Yet because each manufacturer terminal hardware system there are differences, some terminal may adopt the charging of other types and transfer of data/synchronous multiplexing port, data wire.So, comprising of data wire nature of the present invention: usb data line, and the multiplexing data wire of other support charging/transfer of data.That is to say, the present invention does not limit the port type of data wire connecting terminal, as long as have charging and transfer of data/synchronizing function concurrently after inserting data wire (at all events type), promptly can adopt intelligent charging method proposed by the invention, charging and transfer of data/simultaneous operation are distinguished, and carried out intelligentized Charge Management.
Below in conjunction with Fig. 1, intelligent charging method provided by the present invention is elaborated, and for convenience of description, follow-up will be that example is described with the usb data line.As shown in Figure 1, this method mainly may further comprise the steps:
Terminal detects the connection situation of data wire in real time, when detecting data wire and connected PC and terminal, judges further whether the user selects to enter USB intelligent charge pattern, and when judging that the user selects to enter USB intelligent charge pattern, execution in step 103; Otherwise, execution in step 106.So-called intelligent charge pattern is meant a kind of mode of operation newly-increased in terminal, when terminal works in intelligent charge pattern following time, terminal can be charged according to intelligent charging method of the present invention; When terminal is not operated in intelligent charge pattern following time, terminal then can be charged according to existing charging method.Whether enter USB intelligent charge pattern, can select by the user interface (UI, User Interface) that terminal provided by the user.
When the battery voltage value of terminal judges collection is higher than the battery pre-charging voltage threshold, thinks to need not charging, and then the charge function of self inside is forbidden, thereby only enter transfer of data/synchronous regime.
Need to prove, predetermined battery pre-charging voltage threshold can be by the software systems charging module inner setting of terminal, the fixed software systems requirement or the battery attribute by different terminals of getting of occurrence decided, can be chosen for the terminal setting voltage that the first time, low-current alarming was reminded as this threshold value, also can be chosen for the battery low-voltage or the voltage percentage of other settings; This threshold values can also be set by the UI that terminal provided by the user, selects for the user as a plurality of voltage dividing values that singly select can be provided, and perhaps provides the high, medium and low cell voltage that waits to select grade to select for the user.In a word, the form of UI can be rich and varied.
This shows that identical with the optional function of " whether charging when being connected to PC after the start " of providing in the prior art is that the intelligent charging method that the present invention proposes also provides the optional function of a kind of " On/Off intelligent charge "; Different is, after intelligent charge function of the present invention is opened, terminal enters a kind of pattern of intelligent charge, promptly when terminal by data wire with after PC is connected, the embedded software system of terminal can according to the current battery voltage situation automatically control whether the battery of terminal is charged, thereby avoided each connection data wire all to the imperative operation of battery charge, made the charge function intellectuality and the hommization more of terminal.In addition, intelligent charging method of the present invention is realized simple, can be on the basis of the hardware system that does not change terminal the internal drive of software systems by revising terminal and application code and UI function interface realize.The present invention also need not the user and is provided with whether charging as required at every turn, and this has strengthened user experience greatly, and has better realized the theory of intelligent terminal " intellectuality ".
Be example with double-core (mARM+aARM) smart mobile phone more below, the intelligent charging method of above-mentioned terminal is further elaborated based on Windows Mobile.Wherein, the aARM side mainly is responsible for the battery-operated relative program of smart mobile phone, and mARM mainly is responsible for the charging control of smart mobile phone.
The realization flow of aARM side as shown in Figure 2, mainly may further comprise the steps:
Revise the UI of smart mobile phone upper layer application system, promptly in charging is provided with, increase the optional function of USB intelligent charge, simultaneously the corresponding content of internal system registration table is made amendment.The setting means of battery pre-charging threshold voltage V can be that internal system is set or the user sets, if the user sets, so also need the UI of application system to make corresponding adjustment, guarantee that promptly UI can provide the optional function option of USB intelligent charge to select for the user.
Step 202, the usb data line that detects smart mobile phone in the battery-operated program of aARM side in real time connects situation, has connected PC and smart mobile phone if detect the usb data line, execution in step 203; Otherwise, do not do further operation.
The mARM lateral root is controlled the USB charge function according to the value of opening USB charge function flag bit flag.If flag is TRUE, then open the USB charge function, the charging hardware configuration that operation is relevant; If flag is FALSE, then close the USB charge function, the charging hardware configuration that operation is relevant.Yet, there are the following problems in meeting when practical application: when the aARM side is not released, promptly smart mobile phone do not start shooting or in start process the aARM side be not loaded under the situation about finishing, the mARM side is to read the effective value of unlatching USB charge function flag bit flag that the aARM side provides, can only read the initialization value of mARM side, rather than the set point of actual aARM side.Therefore, need be at the mARM lateral root according to memory value of the preceding flag effective value that the aARM side is set when once starting shooting record, this memory value can not disappear because of the opening and closing of smart mobile phone.A NV item value can selecting smart mobile phone herein when the value of start back unlatching USB charge function flag bit flag changes along with user's setting, is then given the flag value this NV item value as this memory value.And when not starting shooting or in start process, insert the usb data line, then can judge whether open USB intelligent charge function according to this NV item value, avoided smart mobile phone like this when not starting shooting or insert the usb data line in start process, the inconsistent situation of the selection of the response function of smart mobile phone and user's reality takes place.
The specific implementation flow process of mARM side as shown in Figure 3, mainly may further comprise the steps:
Step 301 judges whether the aARM side discharges, if, execution in step 302; Otherwise, execution in step 304.
Step 302 reads the value of opening USB charge function flag bit flag.
Step 303 judges whether the value of flag is TRUE, if, execution in step 306; Otherwise, execution in step 308.
The USB charge function is opened or closed to step 304 according to the value decision of NV item.
Step 305 judges whether the value of NV item is 1, if, execution in step 306; Otherwise, execution in step 308.
The USB charge function is opened in step 306～307, and the value that writes the NV item is 1.
The USB charge function is closed in step 308～309, and the value that writes the NV item is 0.
From the flow process of Fig. 3 as can be seen, under the situation that the aARM side discharges, decide according to the value of flag and to open or to close the USB charge function; Under the situation that the aARM side does not have to discharge, decide according to the value of NV item and to open or to close the USB charge function.Such operation has avoided smart mobile phone when not starting shooting or insert the usb data line in start process, and the inconsistent situation of the selection of the response function of smart mobile phone and user's reality takes place.
In addition, the optional function of " On/Off intelligent charge " of the present invention, also can combine with the optional function of " whether charging when being connected to PC after the start " in the prior art, the selection of these two kinds of functions promptly is provided in terminal, when the user selects the optional function of " On/Off intelligent charge ", carry out intelligent charge flow process of the present invention; When the user selects the optional function of " whether charging when being connected to PC after the start ", carry out in the prior art corresponding operating that should function.
For realizing the intelligent charging method of above-mentioned terminal, the present invention also provides a kind of intelligent charger of terminal, and as shown in Figure 4, this device mainly comprises: magnitude of voltage acquisition module 10, comparison module 20 and state processing module 30.
Wherein, magnitude of voltage acquisition module 10 is used for when terminal is connected on the PC by data wire, in real time acquisition terminal current battery voltage value.Magnitude of voltage acquisition module 10 detects the connection situations of data wires in real time, when detecting data wire and connected PC and terminal, judges whether to enter the intelligent charge pattern, and when judgement enters the intelligent charge pattern, gathers the current battery voltage value in real time.
Comparison module 20 is used for battery voltage value that magnitude of voltage acquisition module 10 is gathered and the battery pre-charging voltage threshold of being scheduled to and compares, and obtains comparative result.State processing module 30 is used for according to comparative result, when the battery voltage value of gathering is not higher than the battery pre-charging voltage threshold, enters charging and transfer of data/synchronous regime simultaneously, otherwise, only enter transfer of data/synchronous regime.Concrete, when comparison module 20 was not higher than the battery pre-charging voltage threshold at the battery voltage value of gathering, it was TRUE that the flag bit flag that opens charge function is set; When the battery voltage value of gathering was higher than the battery pre-charging voltage threshold, it was FALSE that the flag bit flag that opens charge function is set; State processing module 30 reads the value of the flag bit flag that opens charge function, if flag is TRUE, then enters charging and transfer of data/synchronous regime simultaneously; If flag is FALSE, then only enter transfer of data/synchronous regime.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
