Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
Be illustrated in figure 1 as a flow process synoptic diagram of the condition control method of the embodiment of the invention, this condition control method is applied to first electronic equipment, described first electronic equipment is portable electric appts normally, panel computer for example, notebook computer, the smart mobile phone that power consumption is bigger etc., described first electronic equipment comprises one for the connectivity port that is connected with second electronic equipment, described second electronic equipment can be by described connectivity port to described first power electronic equipment, the electric weight that consumes when wherein, second electronic equipment system that can be lower than first electronic equipment for the electric weight that first electronic equipment provides normally moves.Described second electronic equipment can be electronic equipments such as desktop computer or notebook computer, usually has a connectivity port on described second electronic equipment, with the connectivity port on first electronic equipment be the port of same type, be used for being connected with the connectivity port of first electronic equipment.
In order to guarantee first electronic equipment by second power electronic equipment time, normal operational system, the condition control method of the embodiment of the invention may further comprise the steps:
Whether step 101, detection system are just carrying out the start operation;
The system of first electronic equipment is made up of hardware and software two parts of first electronic equipment, and hardware comprises central processing unit (CPU), storer and external unit etc., and software refers to the working procedure of first electronic equipment and corresponding document etc.
The value of described predetermined threshold value can be set as required.
For example, described predetermined threshold value can be set at: when the battery electric quantity of described first electronic equipment equaled predetermined threshold value, the electric weight in the battery added the electric weight that second electronic equipment provides, and just in time equaled the electric weight that the normal operation of system consumes.That is to say that when the battery electric quantity of first electronic equipment was lower than predetermined threshold value, the electric weight in the battery added the electric weight that second electronic equipment provides, be lower than the electric weight that the normal operation of system consumes, that is to say, be difficult to keep system and normally move.
Above-mentioned two conditions: 1) system is by second power electronic equipment; 2) battery electric quantity is lower than predetermined threshold value, in the time of need satisfying simultaneously, just needs control system to switch to low power consumpting state, when one of them condition does not satisfy, does not all need control system to switch to low power consumpting state.That is to say, when system is not by second power electronic equipment, for example, when being powered by civil power (220V), because civil power can provide more powerful electric weight, be enough to provide system's electric weight that normal operation consumes, thereby, do not need system is switched to low power consumpting state.In addition, when battery electric quantity is higher than predetermined threshold value, for example, when the electric weight that equal battery provides is enough to provide system normally to move the electric weight that consumes, then do not need system is switched to low power consumpting state.That is to say to have only when above-mentioned two conditions all satisfy, just need control system to switch to low power consumpting state.
The electric weight that system consumes under low power consumpting state will be lower than the electric weight that system consumes under normal operating condition, the low power consumpting state of described first electronic equipment can for: the brightness of the display screen of first electronic equipment is less than default brightness (for example, brightness drops to minimum value), the running frequency of the CPU of first electronic equipment is lower than predeterminated frequency (being the CPU low-frequency operation), first electronic equipment the running frequency of storer be lower than predeterminated frequency (being the storer low-frequency operation) and/or close other equipment that normal operation does not exert an influence to system, for example 3G, wifi, it is first-class to make a video recording.
Because the electric weight that consumes under low power consumpting state of system is no more than the supply electric weight that obtains from second electronic equipment, thereby system still can move normally, and can keep the operation of some low-power consumption, for example data sync operation etc.
If light the display screen of electronic equipment, usually need to consume a large amount of electric weight, thereby, in order to guarantee the normal operation of system, in above-described embodiment, after the display screen of first electronic equipment is lighted, can temporarily no longer be battery charge, that is to say, the electric weight that second electronic equipment is provided when the user no longer needs to use the first electronic equipment executable operations, can be closed the display screen of first electronic equipment all for the operation of system, when first electronic equipment detects display screen and cuts out, can continue to be again battery charge.
Be illustrated in figure 2 as another schematic flow sheet of the condition control method of the embodiment of the invention, described condition control method may further comprise the steps:
Whether step 201, detection system are just carrying out the start operation;
Whether step 204 detects display screen and lights;
Whether step 206 detects described display screen and closes;
Step 207 when detecting described display screen and close, is connected the charging path between described battery and the described connectivity port.
First electronic equipment and the connectivity port on second electronic equipment in above-described embodiment can be polytype connectivity port, for example USB port.
USB port generally includes: VS (power supply) line, VSS () line, D+ (data) line and D-(data) line.In the embodiment of the invention, after the power lead of judging USB port receives the power supply of externally fed equipment, can be by judging whether D+ line and D-line on the USB port be direct-connected, judge that whether first electronic equipment is just by second power electronic equipment, when D+ line and D-line are direct-connected, first electronic equipment is described just by mains-supplied, when D+ line and D-line are not direct-connected, illustrates that first electronic equipment is just by second power electronic equipment.
The condition control method that provides by above-described embodiment, after the electronic equipment start, the system that detects is just by other power electronic equipment, and the battery electric quantity of self can switch to low power consumpting state with system during less than predetermined threshold value, and this electronic equipment is under the low power operation state, the consumes power of system is no more than the supply electric weight that obtains from powered electronic device, thereby can keep the normal operation of system, to be charged finishing such as no longer need after, the system of reruning.
Corresponding to above-mentioned condition control method, as shown in Figure 3, the embodiment of the invention also provides a kind of electronic equipment, and this electronic equipment comprises:
Whether start detection module 302 is just carrying out the start operation for detection of system;
If light the display screen of electronic equipment, usually need to consume a large amount of electric weight, thereby, in order to guarantee the normal operation of system, in above-described embodiment, after the display screen of first electronic equipment is lighted, can temporarily no longer be battery charge, that is to say, the electric weight that second electronic equipment is provided when the user no longer needs to use the first electronic equipment executable operations, can be closed the display screen of first electronic equipment all for the operation of system, when first electronic equipment detects display screen and cuts out, can continue to be again battery charge.
Based on foregoing description, the electronic equipment of the embodiment of the invention can also comprise:
Light detection module, whether light for detection of display screen.
