Abstract
The invention discloses an improved USB power supply structure, comprising a main controller and a root hub. An input end of the main controller is connected with a transmission port, and an output end of the main controller is connected with the root hub through a data transmission line. An output end of the root hub is provided with a plurality of data interfaces which are connected with serial data lines and data power lines respectively. Beneficial effects of the improved USB power supply structure are simple structure, well designed, and through improvement for inner structure of a conventional USB, the power supply can be used to charge a plurality of communication devices. The improved USB power supply structure has certain economic value and industry value.
Description
Technical field
The present invention relates to USB device field, specifically, specially refers to a kind of modified model USB power supply architecture.
Background technology
USB; It is the abbreviation of English Universal Serial BUS (USB); And its Chinese abbreviate as " USB ", be an external bus standard, be used for being connected and communication of standard computer and external equipment; Be the interfacing that is applied in the PC field, the plug and play of USB interface support equipment and hot plug function.
Application number is that 201010105377 patent application document discloses a kind of supply socket with USB interface; Comprise have attaching plug, the jack body of power line and electric power accessory power outlet; Wherein, said jack body is provided with USB interface, is provided with pcb board and current commutates potential device in the said jack body; Said USB interface is electrically connected in said current commutates potential device; Said current commutates potential device is electrically connected in said pcb board, and said pcb board is electrically connected in said power line, and said jack body has upper body and lower case; Said upper body is fastened and connected in said lower case; Said electric power accessory power outlet and USB interface are located on the said upper body, also are provided with power switch device or on off state display lamp on the said upper body, and said electric power accessory power outlet is three sockets or two sockets.
But this device is based on that supply socket transforms, and the internal structure of USB is not improved, and its compatibility still has deficiency.
Summary of the invention
The object of the present invention is to provide a kind of modified model USB power supply architecture, improve, strengthened its compatibility, overcome the deficiency in the conventional art, thereby realize the object of the invention through internal structure to traditional USB.
The technical problem that the present invention solved can adopt following technical scheme to realize:
A kind of modified model USB power supply architecture comprises master controller and Root Hub, and the input of said master controller connects transmit port, and the output of master controller is connected with Root Hub through data line; The output of said Root Hub is provided with the plurality of data interface, connects serial data line and data power line respectively.
In one embodiment of the invention, the quantity of the data-interface of said Root Hub output setting is 4, comprises 2 serial data line interfaces and 2 data electric source line interfaces.
In one embodiment of the invention, said master controller and Root Hub are packaged in the housing.
Beneficial effect of the present invention is: simple in structure, design ingeniously, and improve through internal structure traditional USB, use applicable to the charging of multiple communication equipment, have certain economic and be worth and industrial value.
Description of drawings
Fig. 1 is the structured flowchart of a kind of modified model USB power supply architecture of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, a kind of modified model USB of the present invention power supply architecture comprises master controller 100 and Root Hub 200, and the input of said master controller connects transmit port, and the output of master controller is connected with Root Hub through data line; The output of this Root Hub is provided with the plurality of data interface, connects serial data line and data power line respectively.
In the present embodiment, the quantity of the data-interface of Root Hub output setting is 4, comprises 2 serial data line interfaces and 2 data electric source line interfaces; Said master controller and Root Hub are packaged in the housing, and what this master controller adopted is single-chip microcomputer.
The present invention adopts quadded cable, and wherein two is the serial-port that is used for transmitting data, and in addition two provide power supply for downstream (Downstream) equipment, and for high speed and need the peripheral hardware of high bandwidth, USB is the transmission data of 12Mbps at full speed; For the low speed peripheral hardware, USB then transmits data with the transmission rate of 1.5Mbps.
What deserves to be mentioned is; Root Hub is the special component in the USB structure, and it provides the equipment of naming a person for a particular job that is called port (Port) to be connected on the usb bus, detects the equipment on the bus that is connected simultaneously; And, be responsible for the fault detect and the recovery of bus for these equipment provide power management.Line concentration can be bus the energy is provided; Also can be self provides the energy (obtaining power supply from the outside); Self providing the equipment of the energy can insert bus provides in the hub of the energy; But hub that bus provides the equipment of the energy not insert self provides the energy or support surpass in four the downstream port, when providing the needs of energy device to surpass the 100mA power supply like bus, can not provide the hub of power supply to connect with bus.
Of the present invention simple in structure, reasonable in design, improve through internal structure traditional USB, use applicable to the charging of multiple communication equipment, have certain economic and be worth and industrial value.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
Claims (4)
