Description
Technical field：
The present invention relates to the recognition methods of field of communication technology more particularly to a kind of DRP electronic equipments and devices.
Background technology：
General-purpose serial bus USB Type-C is referred to as USB-C, it is a kind of novel USB cable and the specification of connector, fixed
A whole set of completely new USB physical specification including connector, port, container and cable etc. of justice, is USB3.0 interfaces
A part.The following Type-CtoType-C interfaces, i.e., direct-connected both ends are all Type-C interfaces, become increasingly to flow in the future
Row.
Equipment with USBType-C interfaces is generally divided into Three role：（1）DFP, i.e. downlink port（Downstream
Facing Port）, it can be understood as main equipment, DFP provide VBUS, can also provide data, specific implementation is current mirror
Or pull-up resistor.Typical DFP equipment is power supply adaptor.（2）UFP, i.e. uplink port（Upstream Facing Port）,
It can be understood as from equipment, UFP takes electricity from VBUS, and provides data, and specific implementation is pull down resistor.Typical UFP
Equipment is mobile hard disk or USB flash disk.（3）DRP, i.e., double role ports（Dual Role Port）, D FP main equipments can have both been done,
UFP can be from equipment, can also carry out switching at runtime between DFP and UFP, specific implementation be DFP and UFP between the two
Switch in turn.Typical DRP equipment is computer or mobile power.Switching between DFP and UFP according to USB-PD communication protocols,
USB-PD communication protocols are a kind of new power supply and communication connection type, it allows transmission between USB device to be up to the work(of 100W
Rate, while it can change the attribute of port, and port can also be made to switch between DFP and UFP（toggle）, can also be with electricity
Cableless communication obtains the attribute of cable.
When DRP is connect with DRP, connection relation is established at random, is at this time needed user to interact and is confirmed；As DRP and DFP and
When UFP connections, connection relation is established certainly（attached）, at this time interact and confirm there is no need to user；So being set for DRP
For standby, need to confirm whether other side is DRP role, if so, calling interactive interface；If it is not, not having to then call interaction circle
Face.But USBType-C interfaces are when two equipment are connected with each other, the presetting pattern of None- identified other side.
Invention content
In view of this, the present invention provides a kind of DRP recognition methods and device, set with solving two electronics in the related technology
The problem of for the presetting pattern of None- identified other side when being connected by USBType-C interfaces.
According to the first aspect of the embodiments of the present disclosure, a kind of DRP recognition methods is provided, all configuration USBType- are suitable for
