Embodiment
Describe the present invention below with reference to the accompanying drawings in detail.
In an embodiment of the present invention, provide a kind of method for managing power supply based on terminal equipment operation mode.This method for managing power supply mainly is to add the control of equipment work pattern on the basis of charging processes such as original battery impulse, constant current, trickle, when the big current work state of equipment, closes battery charge to improve the stability of system; Charge closing under the voice call state is improved communication effect; According to external power supply and different business functions, close soft accordingly, hardware capability module, to reach maximum power savings, prolong battery service time.
In the 3G terminal product, be example with 3G MODEM, it provides multiple interfaces, comprising: the RJ11 interface, utilize this interface can external telephone set so that voice call function to be provided; The RJ45 interface provides data services such as online.Based on the special function of use of 3G MODEM, its external adapter provides 12V direct current, and the 7.2V Ni-MH battery provides stand-by power supply.
When 3G MODEM is charged, because when cell voltage is low, charging current is very big, and data, speech business operation this moment (the especially online under the EDGE environment and the conversation of external phone) is very big to the demand of electric current, the power supply that is applied on the terminal equipment is subjected to multiple restrictions such as structure, cost, and it is very difficult requiring several aspects such as its quality that can take into account application stability, miscellaneous service, power consumption.
In order to make job stability and the battery charging management that under big current working mode, can take into account voice, data service such as the multiple 3G portable terminal of 3G MORDEN, as shown in Figure 1, the method for managing power supply based on terminal equipment operation mode according to the embodiment of the invention is as follows to its processing: under the situation of terminal equipment by supplied with power through external adapter, carry out power management respectively according to data, voice application functions; And under the battery-powered situation of terminal equipment, carry out power management according to product work, standby mode.
Wherein, under the situation of terminal equipment, when having data service or speech business, further comprise following processing: under big current working mode, close battery charging function by supplied with power through external adapter; Under little current working mode, open battery charging function; Under the phonological working pattern, close battery charging function; And under the non-voice mode of operation, open battery charging function.
And, under big current working mode, turn-on data mode of operation software/hardware functional module, deal with data business; Under little current working mode, close datamation pattern software/hardware functional module.And under the phonological working pattern, start speech business software/hardware functional module, processed voice business; Under the non-voice mode of operation, close speech business software/hardware functional module.In addition, under little current working mode or non-voice mode of operation, dynamically adjust charge parameter according to operating state.
In the method, under the battery-powered situation of terminal equipment, when having data service, the corresponding software/hardware functional module of turn-on data mode of operation, and when not having data service, close network function; When having speech business, the professional software/hardware functional module of opening voice; And when not having speech business, closing speech business software/hardware functional module, system enters energy-saving mode.
Preferably, when implementing, reality can define: the symbol definition below following in the description at presents according to following symbol:
Extpwr_flag: external power adapter sign;
Charg_flag: battery charge sign;
Hook_flag: phone dislodging machine sign;
Data_flag: data service sign;

System_Active_Flag: system works, park mode sign.
When reality is implemented, above-mentioned symbol definition can be applied in the method shown in Figure 1, the implementation step of this method as shown in Figure 2:
(1) check whether external power supply is arranged, if having, Extpwr_flag=1 then;
(2) check whether data service is arranged, if having, Data_flag=1 then enables that business of networking is soft, the hardware capability module;
(3) when Data_flag=1, if belong to big current data business, then Maxcurrent-flag=1; When Data_flag=0, check that speech business is provided with hook_flag;
(4) according to Maxcurrent-flag or hook_flag state the charging sign is set, charg_flag=0 when big electric current business or phonetic function;
(5), carry out detailed charging process control according to charging sign charg_flag; And
(6) enable that each business function is soft, hardware module, close according to the sign of front and control, realize the modularization management of device power supply (DPS).
By top description as can be seen, whole power management and charged state control are controlled by operating system and are regularly to carry out, and can guarantee in time, realize effectively the power management of equipment.
In sum, compare with method in the past according to the power management of present embodiment, changed the irrelevant design of terminal equipment battery charge mode of operation concrete in the past with it, refinement the controlled condition of device power supply (DPS) management, it has following having a few: according to mode of operation, under big current-mode, stop charging, reduced device power supply (DPS) pressure, make that the hardware implementation cost of power supply reduces greatly, device power supply (DPS) stability improves; Improved at equipment and be in phonetic function under the GSM pattern, can produce falling of voltage at the pulse current charge of battery, thereby and cause the problem that the noise of voice call produces, charge closing is to improve speech quality; When having incoming call or caller to breathe out, in real time according to the mode of operation charge closing, the cost that this has promptly reduced the power supply design, also improved equipment work stability, improved calling quality; According to the equipment work pattern, closing does not have professional soft, the hardware capability module of using, and realizes the efficient utilization of device power supply (DPS), helps prolonging battery operated stand-by time.
This method for managing power supply based on the equipment work pattern is applied to can reach good effect in the 3G MODEM product, promptly saved the power supply design hardware cost, reduced the integrated circuit board area, improved the stability of equipment, the problems of improving the voice call effect, having avoided like product power management in the past to be brought again.
Along with constantly popularizing that 3G uses, the wireless terminal product of high power consumption can get more and more, the stability of its work and long-time standby performance requirement are more and more higher, also can be applied in other on power source performance and cost, the structural requirement high product based on the method for managing power supply of equipment work pattern, have general applicability.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
