The module can be mounted at the blank area of mobile phone, while the module, via connector is connected to relative interface of mobile phone, or the module is directly designed on the circuit board, then mounting USB interface on the mobile phone; the computer and mobile phone can write, delete and execute the document of module.
Description
Technical field
A kind of can be directly and the mobile phone with USB interface computer interaction, that be used for exchanges data, use and relate to mobile phone, notebook and desktop computer, belong to the information equipment technical field.
Technical background
The exploitation of mobile phone (hereinafter to be referred as mobile phone) is used, bring great convenience for people's life, work, mobile phone of today can not only be made a phone call, and can surf the Net, sends short messages, send out and receive Email, fax, take a picture, listen MP3, play games and multimedia application.But no matter how the function of mobile phone develops, owing to do not have fine solution all the time with the interaction of computer, colourful resource in the computer can not be passed to mobile phone easily, and the use of mobile phone still rests in the communication basically.For example, the present mobile phone of producing, without exception and the contact between the computer, all be the special-purpose software that this model mobile phone need be installed on computers, on the operating platform of this software, communicate then, not only troublesome poeration, for computer operation is not very skilled people, be difficult to carry out, not can use not installing on other computer of this software still more, so in fact few people carry out this interaction; The various functions of cell phone manufacturer's propaganda are also just made a discount greatly, and this problem has obviously become the bottleneck of restriction mobile phone technique development.
Summary of the invention
Purpose of the present invention provides a kind of mobile phone that is used for exchanges data with USB interface; By this USB interface, mobile phone can with any one computer realization exchanges data with USB interface.
Technical scheme of the present invention is achieved like this: the basic structure of mobile phone is not done big change, and usb interface module is installed in mobile phone, and module is connected with relevant interface in the mobile phone by plug connector, again by the USB interface on the mobile phone, is connected with computer; Perhaps module is directly designed on circuit board of mobile phone, USB interface is installed on mobile phone again, whole like this handset structure is more compact, and is more reasonable; Usb interface module is made up of a microprocessor, large capacity data memory, data converter, standard USB interface, it is characterized in that: the data port of microprocessor MCU is connected with the data storage data port, the control mouth is connected with the data switch respectively, and the switching of control data chain, slot data D+ in serial data mouth D+, D-on the microprocessor MCU and needed positive and negative power supply thereof and the USB interface, D-and positive and negative power supply are connected; When module is connected with computer, microprocessor MCU and data converter in the module provide power supply by computer, and the needed power supply of data storage work is by power supply of microprocessor control mouthful output, or the scheme of employing DC-DC, power to data storage by computer; When the USB interface of module and computer disconnected, module was without external power supply; The control mouth of microprocessor MCU is access hole, the data switch of control storage respectively; When the USB interface of module was connected with computer, microprocessor MCU control data switch blocked automatically with the data of the control system of mobile phone and is connected, and set up and the communicating by letter of computer.
Data storage can be a micro hard disk, also can be " flash memory " class chip.
Beneficial effect is: 1, by the USB interface on the mobile phone, mobile phone can with any computer interaction with USB interface, the specific drivers of mobile phone need not be installed again, use simple; 2, usb interface module does not take the memory source of mobile phone, and can be used as the large-scale file of " another memory " storage of mobile phone; 3, on mobile phone and computer, can both read, write, delete the file in the usb interface module.4, the basic structure of mobile phone is not done big change.
Description of drawings
Fig. 1 is electric functional-block diagram.
Fig. 2 is with pack into the schematic configuration diagram of mobile phone inside of usb interface module.
Among Fig. 2, (1) mobile phone, (2) mobile phone display screen, (3) module board, (4) USB interface, (5) data switch, (6) data storage, (7) microprocessor MCU.
Embodiment
Figure (2) is the embodiment that usb interface module is placed in the mobile phone idle place, and module is by module board (3), USB interface (4), and data switch (5), data storage (6), microprocessor MCU (7) forms; Its electric theory diagram is seen Fig. 1, and the broad arrow among Fig. 1 is represented data chainning, and thin solid arrow line is represented supply line.As the microprocessor MCU (7) of control chip, by the operation of data/address bus control whole system, its data port is connected with the data port of data storage (6); The D of microprocessor MCU (7)
+, D
-The positive and negative interface of mouth, power supply and the D in the USB interface (4)
+, D
-The both positive and negative polarity of groove, power supply connects, and USB interface (4) provides working power to data switch (5) simultaneously; The power output of microprocessor MCU (7) is connected with data storage (6), or adopts outside DC-DC power transfer module to provide power supply by USB interface (4) to data storage (6); The control mouth of microprocessor MCU (7), access hole, the data switch (5) of difference control data memory (6), when the USB interface on the mobile phone (4) is connected with desk-top or notebook, microprocessor MCU (7) control data switch (5), data chainning is switched, being connected of the control system of automatic disconnection and mobile phone, and carry out two-way interaction and exchanges data with computer; When USB interface (4) disconnected with being connected of desk-top or notebook, data switch (5) was connected data chainning again automatically with cellphone control system.Therefore on mobile phone or computer, can both read, write, delete the file data in the usb interface module.Again do not need to install the specific drivers of mobile phone on computers, more not be used under the interface of this special-purpose software and operate, only need open the drive of representing this module, open corresponding file again, adopt then and duplicate, method such as dilatory can both write data easily, and having made things convenient for computer operation is not very skilled people's use.
During use, after the USB interface (4) of mobile phone and computer successful connection, microprocessor MCU (7) is control data switch (5) automatically, with data chainning by with switch to being connected of mobile phone and being connected of computer; Open " my computer " of computer then, find " portable hard drive ", click is opened, set up corresponding file, as Music music, Pictures picture, Ebooks e-book, Java apps program (recreation) etc., the data of needs is copied in the computer get final product in the corresponding file again, if data was just arranged in the file originally, can directly move these programs or deletion, as the recording in the mobile phone, Video Document being copied on the computer.When disconnect with being connected of computer after, data switch (5) is connected the data chainning of module again automatically with mobile phone, just can be on the menu of mobile phone, find corresponding document in the module in the column accordingly, and work such as move, delete, duplicate; As file copy that can the data in the mobile phone EMS memory, photo, video recording etc. are bigger in the module in the corresponding file; Or, see animation, photo etc. at Pictures at the pleasant to the ear MP3 of Music music.Because during the corresponding document in the operation module, module just is equivalent to a memory on the mobile phone, does not occupy the memory source of mobile phone, has therefore realized in module the data storage high capacity.
