Illustrate that another Type-c interface has accessed charging equipment, current two Type-c interface roles setting is Slave shape
State；Conversely, when first PD control device detect its GPIO2 mouthfuls level be low level when, then can determine another Type-c
Interface does not have access device, and current Type-c interface role is set as Master state.
When detecting that current Type-c interface is extracted, it is that low level is another to inform that GPIO1, which is actively arranged, in PD control device
A Type-c interface, to indicate that current Type-c interface has been extracted, while switching current Type-c interface role is Slave shape
State.
In power distribution output step, PD control device sets the output of output interface according to the role of Type-c interface
Power.When the role of Type-c interface is Master state, the output power that its output interface is arranged in PD control device is 30W,
Increase output power；When the role of Type-c delivery outlet is Slave state, the power that its output interface is arranged in PD control device is
18W reduces output power, so as to ensure that two Type-c interfaces all have the ability for adjusting output power.
It can be seen that method of the invention can be with care testing device into and out state, and obtain in real time defeated
The state of outgoing interface and the output power for adjusting port, when only single interface equipment access, single port output power is high-power
Output；When two interfaces have equipment access simultaneously, the power of two output interfaces is all small-power output, is wherein appointed when extracting
After the equipment of what Type-c interface, the remaining Type-C charge port automatic power adjustment that do not pull out is high-power output.
So the present invention optimizes charge efficiency by more mouthfuls of power of smart allocation, the charging of electrical equipment can be accelerated
Speed；Compensating for the prior art can not achieve the defect of more mouthfuls while power distribution, can be achieved at the same time two output ports
Power distribution greatly optimizes charge efficiency.
It should be noted that the above is only a preferred embodiment of the present invention, but the design concept invented is not limited thereto,
All insubstantial modifications made using this design to the present invention, are also fallen within the scope of protection of the present invention.
