Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and not
It it is whole embodiments.Based on the embodiment in the present invention, those skilled in the art are not making creation
The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.
The present invention provides a kind of fax transmission control method, and the executive agent of the method is portable power source, accesses
Equipment can be the electronic equipments such as USB flash disk, portable hard drive, mobile phone or panel computer, when portable power source passes through
When data wire is connected with access device, the present invention provides a kind of fax transmission control method, it is possible to achieve mobile
Fax between power supply and access device is defeated.Refer to Fig. 1, the fax transmission control method that the present invention provides
One embodiment includes:
101, the level of the Type-C port of portable power source detection access device, determines according to level change
The port role of access device；
In the present embodiment, the two ends of data wire are provided with Type-C port, a Type-C of data wire
Port is connected with the Type-C port of portable power source, and another Type-C port of data wire sets with access
Standby Type-C port is connected.Wherein, the Type-C port of portable power source is double role's port (Dual Role
Port, DRP), Type-C port is provided with collocation channel (Configuration Channel, CC) pin,
Portable power source is additionally provided with the CC logic chip corresponding with CC pin, and port includes uplink port and descending
Port, portable power source can switch between, when portable power source port is as uplink port,
Port role is for treating fill device；When portable power source port is as downlink port, port role is that power supply sets
Standby.
When portable power source is connected by data wire with access device, the CC pin of portable power source sets with access
Standby CC pin connection, portable power source can detect the level of self CC pin, and detect that access sets
The level of standby CC pin.
Concrete, when the CC logic chip of portable power source detect in access device the level of CC pin from
When high level is set to low level, show that have passed through one through the level of CC pin is pulled down to common port
The resistance of (Ground, GND), portable power source may determine that access device, for treating fill device, and determines
Electricity transmission mode is powering mode, is i.e. powered to access device by portable power source.Wherein GND is an electricity
Pressure reference point, can be ground, it is also possible to refer to power cathode, be not construed as limiting herein.
When the CC logic chip of portable power source detects that in access device, the level of CC pin is put from low level
During for high level, show through the level of CC pin have passed through one be pulled to VBUS (Voltage Bus,
Bus-powered) resistance, portable power source may determine that access device is power supply unit, and determines the defeated mould of fax
Formula is charge mode, is i.e. powered to portable power source by access device.Wherein, power supply unit can be power supply
Adapter, PC (Personal Computer, PC), or other can connect power supply and export electricity
The equipment of stream.
It is understood that portable power source can include one or more Type-C port, wherein CC pipe
Foot can be CC1 pin or CC2 pin.
102, portable power source is according to the port role of access device, and to carry out fax defeated with access device.
Concrete, when the port role of access device is for during until fill device, and VBUS pipe opened by portable power source
Foot, charges for access device；When the port role of access device is power supply unit, power supply unit is opened
VBUS pin, charges for portable power source, and portable power source can receive the electric current of power supply unit output.
