Abstract
The invention discloses a fast charging data line, which comprises a first interface, a second interface and a USB data switch, wherein the first interface is used for connecting portable equipment, the second interface is used for connecting a computer or a power adapter, the first interface is in power supply connection with the second interface; an uplink port of the USB data switch is in data communication connection with the first interface; and two paths of downlink ports of the USB data switch are in data communication connection with the second interface and a protocol recognition IC. Through switching channels of the USB data switch, fast charging of the portable equipment can be achieved; and the channels can be switched to realize a data communication function when in need of data communication. The fast charging data line provides an intelligent data line function for intelligent equipment such as an intelligent mobile phone.
Description
Technical field
The present invention relates to fill data wire for connecting portable equipment and computer or power supply adaptor speed.
Background technology
With scientific and technological and social progress, portable laptop computers, panel computer and intelligent mobile phone are popularized.Institute
Some mancarried electronic aids all use rechargeable battery, carry out data transmission with data wire and charge.
Existing data wire, when use is charged to mancarried electronic aid, charging rate can be very slow；And the filling of independent charge function
Electric wire, does not has data core, needs additionally to prepare data wire and realizes data function, and only has simple data wire short circuit side yet
Formula.
Content of the invention
For the problems referred to above, it is desirable to provide a kind of speed fills data wire.I.e. can realize data function, again can by with
Mancarried electronic aid protocol handshake, it is achieved optimize filling soon of electric current.Have only to a data line and just can realize that mancarried electronic aid passes
Transmission of data and quick-charge function.
For realizing this technical purpose, the solution of the present invention is: a kind of speed fills data wire, including for connecting portable equipment
First interface and the second interface connecting computer or power supply adaptor, first interface and the second interface are for electrical connection；Also include USB
Data switch, the up going port of usb data switch is connected with first interface data communication；Also include protocol identification IC；Usb data is opened
The two-way down going port closed is connected with the second interface and protocol identification IC data communication respectively.
Have many moneys protocol identification IC, MA5887, MA5889 etc. of such as strange rock electronics on market.
As preferably, two-way down going port Zhong mono-tunnel of usb data switch and the second interface data communicate to connect, an other road
Two output pin short circuits connect.
The technical program provides the benefit that: only need a data line, it is possible to realize the quick charge to mancarried electronic aid
With data transmission.There is provided support to the demand of smart mobile phone quick charge.
Brief description
Fig. 1 is the block architecture diagram of the specific embodiment of the invention one.
Fig. 2 is the block architecture diagram of the specific embodiment of the invention two.
Fig. 3 is the reference circuit figure of protocol identification IC MA5887.
Detailed description of the invention
With specific embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of speed of the present invention fills data wire, including for the first interface 1 and the connection that connect portable equipment
Computer or the second interface 2 of power supply adaptor, first interface 1 and the second interface 2 are for electrical connection；Also include that usb data switchs
3, the up going port of usb data switch 3 is connected with first interface 1 data communication；Also include protocol identification IC 4；Usb data switchs
The two-way down going port 31 and 32 of 3 is connected with the second interface 2 and protocol identification IC 4 data communication respectively.
As in figure 2 it is shown, the block architecture diagram of specific embodiment two.On the basis of example one, under the two-way of usb data switch 3
Row mouth Zhong mono-tunnel 31 and the communication connection of the second interface data, two output pin short circuits on an other road 32 connect.Eliminate association
View identifies IC, is the simple version of example one.
As it is shown on figure 3, be the reference circuit figure of protocol identification IC MA5887.
The above, only presently preferred embodiments of the present invention, not in order to limit the present invention, every technology according to the present invention
Any trickle modification, equivalent and the improvement that above example is made by essence, should be included in the guarantor of technical solution of the present invention
Within the scope of protecting.
