Abstract
The invention belongs to the field of mobile electronic equipment and discloses a USB (universal serial bus) interface file transmitter. The USB interface file transmitter is characterized by comprising a microprocessor (1), a storer (2), two USB interfaces (3), operating buttons (4) and a liquid crystal display (5). The microprocessor (1) is electrically connected with the storer (2), the USB interfaces (3), the operating button (4) and the liquid crystal display (5); the microprocessor (1) is used for controlling file transmission; the storer (2) is used for buffering and transmitting files; the operating buttons (4) are used for selecting the files and starting transmission; the liquid crystal display (5) is used for displaying listed files and operating information. The USB interface file transmitter has the advantages that the problem about inconvenience in transmitting the files among mobile storage equipment of a USB flash disk, a storage card, mobile hardware, a mobile phone and the like through a computer is solved, and convenient and efficiency file transmission of the mobile storage equipment is achieved.
Description
Technical field
The present invention relates to a kind of file transfer device, particularly relate to a kind of USB interface file transfer device, belong to mobile electronic device field.
Background technology
The movable storage devices such as current USB flash disk, storage card, portable hard drive, mobile phone can carry out data storage easily.But if data to be carried out and file transfer needs to carry out transfer on computers usually between various movable storage device, it would be very inconvenient to carry out file transfer between each movable storage device.For solving the transmission problem of file between movable storage device, the present invention proposes a kind of USB interface file transfer device.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the present invention proposes a kind of USB interface file transfer device, solve transfer files between the movable storage devices such as USB flash disk, storage card, portable hard drive, mobile phone and can only be carried out the inconvenience of transfer by computing machine, achieve the file transfer of convenience, efficiently movable storage device.
For achieving the above object, the technical solution used in the present invention is: a kind of USB interface file transfer device, comprises microprocessor, storer, two USB interface, action button and LCDs.
Described microprocessor is electrically connected with storer, two USB interface, action button, LCDs respectively.
Described microprocessor is used for control documents transmission; Storer is used for buffering and transfer file; Action button is used for select File and starts transmission; Liquid crystal display dir and operation information.
Two described USB interface, one for connecting source memory device, one for linking objective memory device.
Described microprocessor is also connected with accumulator for providing power supply.
Principle of work of the present invention is: microprocessor provides power supply by accumulator, respectively with storer, two USB interface, action button and and LCDs be connected.Microprocessor internal is built with file operating system, and the file that the memory device that two USB can be connected stores is presented in LCDs in the mode of list.The preservation position of file waiting for transmission and file destination can be selected by action button, and start and cancel transmission.Two USB interface connect source memory device and target storage device respectively, even can carry out unidirectional file transfer between a memory device.If need to carry out swap file transmission direction, the position of source memory device and target storage device can be exchanged.
The invention has the beneficial effects as follows: solve transfer files between the movable storage devices such as USB flash disk, storage card, portable hard drive, mobile phone and can only be carried out the inconvenience of transfer by computing machine, achieve the file transfer of convenience, efficiently movable storage device.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In Fig. 1: 1, microprocessor, 2, storer, 3, two USB interface, 4, action button, 5, LCDs.
Embodiment
As shown in Figure 1, the present invention includes: microprocessor 1, storer 2, two USB interface 3, action button 4 and LCDs 5.
Described microprocessor 1 is electrically connected with storer 2, two USB interface 3, action button 4, LCDs 5 respectively.
Described microprocessor 1 transmits for control documents; Storer 2 is for buffering and transfer file; Action button 4 is for select File and start transmission; Liquid crystal display 5 dir and operation information.
Two described USB interface 3, one are for connecting source memory device, and one for linking objective memory device.
Described microprocessor 1 is also connected with accumulator for providing power supply.
First on source memory interface source memory device and target storage device being connected to two USB interface 3 during use and target memory interface.The file directory of two memory devices can be presented in LCDs 5 in the form of a list by the carry key of action button 4.The file to be transmitted in source memory and the file in target memory can be selected respectively to preserve position by the options button of action button 4.After choosing file waiting for transmission and preserving position, carry out file transfer by the beginning key of action button 4, can by the cancel key interrupt transfer pressing the operation button 4 in transmitting procedure.In the transmitting procedure of file, first file waiting for transmission is transferred in storer 3 and carries out buffer memory under the control of microprocessor 1, and by the file transfer of buffer memory in target memory, because storer 3 have employed RAM random access memory, ensured the transmission speed of file.Source memory and target memory can be the movable storage devices with USB interface such as USB flash disk, storage card, portable hard drive, mobile phone.A kind of USB interface file transfer of the present invention device solves transfer files between mobile storage devices can only carry out the inconvenience of transfer by computing machine, achieve the file transfer of convenience, efficiently movable storage device.
Above embodiment is only illustrate reference of the present invention, do not form any restriction to content of the present invention, obviously under thought of the present invention, can make multi-form structure modify, but these is all at the row of protection of the present invention.
