Embodiment in the application, those skilled in the art's every other implementation obtained under that premise of not paying creative labor
Example, belongs to the protection scope of the application.
The embodiment of the present application provides a kind of OTG economize on electricity processing method, and the OTG economize on electricity processing method can be applied to move
In terminal.The mobile terminal can be the equipment such as smart phone, tablet computer, smartwatch.
Fig. 1 and Fig. 2 is please referred to, Fig. 1 is the flow diagram of OTG provided by the embodiments of the present application economize on electricity processing method, Fig. 2
For another flow diagram of OTG provided by the embodiments of the present application economize on electricity processing method.The OTG economize on electricity processing method, application
In mobile terminal, the method may include following steps:
Step 101, detecting connected OTG peripheral hardware, whether power consumption is stablized, and is turned off function of supplying power if power consumption is stablized, is made
Electric current output is not had on supply lines.
Currently, as long as mobile terminal is connected with OTG peripheral hardware, when OTG peripheral hardware have can store energy component (such as
Battery) when will by mobile terminal be OTG peripheral hardware carry out automatic charging, if the electric current that mobile terminal is provided to OTG peripheral hardware is big
In the electric current of OTG peripheral hardware institute actual consumption, then extra electric current will be filled with into the component of the storage energy of OTG peripheral hardware
Until the component of the storage energy is fully charged.In the prior art, if mobile terminal after the OTG peripheral hardware charging complete
Still continuing power supply to it then can be such that the electric energy of mobile terminal is consumed excessively.The purpose of step 101 is, when this by with movement
When the power consumption for the OTG peripheral hardware that terminal is connected is stablized, illustrate that mobile terminal does not charge to the OTG peripheral hardware again, so
Function of supplying power is turned off further to save the consumption of mobile terminal.
Wherein, when OTG peripheral hardware is connected with mobile terminal, and the OTG peripheral hardware has energy storage component, and mobile terminal will be defeated
Electric current supplies the OTG peripheral hardware by supply lines out, and output electric current a part of mobile terminal is used to charge to OTG peripheral hardware, and one
Divide for being actually used for OTG peripheral hardware.Due to the output electric current of mobile terminal during the charging process be can be changed, that is, fill
The voltage of the energy storage component of OTG peripheral hardware can increase gradually in electric process, be filled with electric current in energy storage component also will with variation,
Therefore, illustrate that energy storage component has been filled with when power consumption is stablized.For example, the electric current of default OTG peripheral hardware consumption is stably held in X milliamperes
It is confirmed as power consumption when maintaining 30 seconds to stablize, wherein X is the value less than 500.It is kept for example, the electric current of OTG peripheral hardware consumption is stablized
300 milliamperes maintain be taken as within 30 seconds power consumption stablize.
Wherein, supply lines is one of the input terminal of OTG peripheral hardware, it is used to power in the embodiment of the present application, is not used in biography
Data turn off function of supplying power if power consumption is stablized, and make not have electric current on supply lines and are output in OTG peripheral hardware from mobile terminal.
At this point, OTG peripheral hardware is powered by the energy storage component of its own, to save the electric energy of mobile terminal.
Step 102, the timer and voltage comparator that mobile terminal is arranged generate the condition of interrupt signal, and restart
Then the timer and voltage comparator set standby mode for the mobile terminal, only response is interrupted.
After closing function of supplying power by step 101, the OTG peripheral hardware being connected with mobile terminal will lean on itself to power,
At this time if the time has been grown necessarily cause the OTG peripheral hardware to run out of energy after work and can not continue, it is therefore desirable to setting is mobile eventually
The timer and voltage comparator at end generate the condition of interrupt signal, and restart timer and voltage comparator in specific feelings
Power supply of the mobile terminal to the OTG peripheral hardware is reopened under condition.
Wherein, the OTG peripheral hardware power consumption connected when mobile terminal is stable, mobile terminal is standby mode and function of supplying power
Shutdown, the OTG peripheral hardware connected at this time are powered by itself.Although the power consumption under standby mode is lower, grow in order to prevent
Time be in this standby mode so that the electricity of connected OTG peripheral hardware is declined the excessive or even OTG peripheral hardware can be by the electricity of itself
Amount runs out of and leads to not continue working, then needs to wake up mobile terminal weight under specific circumstances in the OTG peripheral hardware connected
Newly start to power.For example, the time-out time of setting timer is 30 seconds, then by timer up to or over 30 seconds the case where sets
It is set to the condition that timer generates interrupt signal.
Wherein, when the OTG peripheral hardware power consumption connected is stable, the shutdown of mobile terminal function of supplying power, system is in standby at this time
State, Overall Power Consumption is very low and power consumption is constant, and a resistance is concatenated on the OTG peripheral hardware output end connected, passes through detection electricity
Hinder voltage difference of the two ends it is known that the OTG peripheral hardware connected electric current, when curent change be more than threshold value when think that system is jumped out
Standby mode.Voltage comparator is exactly the resistance both end voltage concatenated on to aforementioned connected OTG peripheral hardware output end
Difference is compared with threshold voltage, achievees the purpose that detect whether mobile terminal jumps out standby mode.For example, can will be connected
OTG peripheral hardware output end on the resistance voltage difference of the two ends that concatenates be less than threshold voltage and be set as voltage comparator and generate interrupt signal
Condition.
Wherein, be arranged mobile terminal timer and voltage comparator generate interrupt signal condition be mobile terminal into
It is pre-arranged to enter standby mode.
Step 103, when detecting that the timer or the voltage comparator generate interrupt signal, the shifting is controlled
Dynamic terminal makes a response the interrupt signal: stopping the timer and voltage comparator, restarting power supply makes the confession
There is electric current output on electric wire, and executes step 101.
Wherein, after OTG peripheral hardware power consumption is stablized, mobile terminal is not just powered for OTG peripheral hardware.At this point, OTG peripheral hardware is by it
The energy storage component of itself is powered, and mobile terminal is set as standby mode at this time to save the electric energy of mobile terminal.But it cannot
It allows OTG peripheral hardware to be powered always by the energy storage component of its own, as OTG peripheral hardware is powered by the energy storage component of its own, needs
Waking up mobile terminal again with a timer expiry interruption is the power supply of OTG peripheral hardware.Simultaneously as OTG peripheral hardware is by it
The energy storage component power supply of itself, the voltage of the energy storage component can decline gradually, while also need the voltage of the energy storage component and one
A preset threshold voltage is compared by voltage comparator, can also be touched when the voltage of the energy storage component is lower than threshold voltage
It is the power supply of OTG peripheral hardware that hair, which interrupts waking up mobile terminal again,.
Wherein, it is the same that timer interruption and voltage comparator, which interrupt triggered operation, is wake-up mobile terminal
Again power for OTG peripheral hardware, therefore, the detection that timer interruption and voltage comparator interrupt without sequencing, as long as the two it
Then mobile terminal will make interrupt signal accordingly one triggering interrupt signal.

Step 1033, when detecting that the timer generates the first interrupt signal, the mobile terminal is to described first
Interrupt signal makes a response；Or
Step 1034, pass through voltage comparator detection and concatenated resistance both ends on the OTG peripheral hardware output end
Voltage difference, and the voltage difference is compared with threshold voltage；
Step 1035, it when detecting that the voltage difference is less than threshold voltage, controls described in the voltage comparator generation
Second interrupt signal；
Step 1036, when detecting that the voltage comparator generates the second interrupt signal, the mobile terminal is to described
Second interrupt signal makes a response.
Wherein, when detecting that the timer generates the first interrupt signal or the voltage comparator generates second and interrupts
It when signal, controls the mobile terminal and first interrupt signal or second interrupt signal is made a response: stopping institute
Timer and voltage comparator are stated, restarting power supply makes have electric current output on the supply lines, and execute step 101.
In some embodiments, when executing step 101, further includes:
The timer and voltage comparator are reset, and stops the timer and voltage comparator.
Wherein, it powers when mobile terminal restarts, makes have electric current output on the supply lines, the energy storage to OTG peripheral hardware
After component recharges, it is also necessary to reset the timer and voltage comparator, and stop the timer compared with voltage
Device, so that the timer is returned to original state with voltage comparator, for next normal use.
