Abstract

The invention provides a data transmission device for use between mobile storage devices. The data transmission device is capable of connecting two mobile devices so that the two mobile devices exchange data with each other, and also capable of performing simple operation, such as copying, moving and deletion, on data in one single mobile storage device. The data transmission device is composed of two USB (Universal Serial Bus) interfaces, a USB control circuit, an LCM (Liquid Crystal Module) liquid crystal display module, a key module (including functions such as confirming, canceling and moving cursor), a battery, a power control circuit, an integrated circuit board, an ARM chip and the like. When mobile storage devices such as a USB flash disk and a mobile hard disk drive are taken out, generally, the data of the mobile storage devices can be processed or exchanged only after the mobile storage devices are connected to a computer. The other devices such as the computer generally are large in size, and undoubtedly very inconvenient to take out; however, the data transmission device is small in size, convenient to carry and single in function, invented aiming at solving the problem.

Description

A kind of for the data transmission device between movable memory equipment

Technical field

The present invention is a kind of for the data transmission device between movable memory equipment, can connect two mobile devices, makes two mobile devices carry out exchanges data; Can also carry out shirtsleeve operation to the data in single movable memory equipment, as copy, move, deletion etc.

Background technology

In the time that people carry the movable memory equipment such as USB flash disk, portable hard drive and go out, generally to connect on computers and could carry out certain operations (as deleted, copy, move etc.) to data above.Such as there being people need to use USB flash disk, and in your USB flash disk, some content is not yet deleted and now be there is no computer at one's side, can operate by this device; For another example in your USB flash disk, some data need to be shared with people, and now there is no computer at one's side, and the USB flash disk that can connect two people by this device directly carries out data transmission.Because the general volume of computer is larger, it is beyond doubt very inconvenient to go out to carry, and this device volume only as big or small as matchbox, is convenient for carrying, and function is single-minded, invents just in order to address this problem.

Summary of the invention

The object of this invention is to provide and a kind ofly can replace computer, carry, with insert with, mainly solve the device of two exchanges data between movable memory equipment.

The technical scheme that realizes above-mentioned purpose is: a kind of device for movable memory equipment, comprise that device has two USB interface (1 in Fig. 1,2), display screen (3 in Fig. 1), function button (to comprise the functions such as confirmation, cancellation, mobile cursor with it, in Fig. 1 4), in box, there are battery, surface-mounted integrated circuit, embedded system chip (as ARM) etc.On surface-mounted integrated circuit, there are USB control circuit, LCM LCD MODULE etc., in ARM chip, there is special embedded OS for the file of the movable memory equipment that inserts USB interface is managed, display screen can show the interface of operating system, and box button is with it for operating the file of screen display.

Adopt after technique scheme, the hot swap characteristics of USB makes the exchanges data between data manipulation and the movable memory equipment to movable memory equipment become very convenient.And whole device volume is little of matchbox, be more convenient for carrying compared with notebook computer, bring facility to people simple operations data and friend's sharing data in the situation that there is no computer.

Embodiment

Below in conjunction with accompanying drawing, the present invention is further detailed explanation with example.

Internal structure of the present invention as shown in Figure 4.Two USB interface are connected with ARM chip, if there is movable memory equipment to insert USB interface, ARM chip, by detecting, identifying and obtain its administrative power, can carry out subsequent operation to data wherein; Display module comprises liquid crystal mesogens display control circuit, liquid crystal display etc., is connected, for showing operation interface and the content of embedded OS with ARM chip; Key circuit is also connected with ARM chip, for inputting user's operation information to operating system; Power module comprises battery, power switch etc., is used to device power supply.The present invention is described in detail to use two examples below.

One, insert the situation (Fig. 2) of two movable memory equipments:

1. two movable memory equipments are inserted respectively to two USB interface (1 in Fig. 1 and 2).

After 2.ARM chip detection to two movable memory equipment, display is sent to information, on-screen-display messages prompting user selects to want the equipment of service data, and user sends information by ACK button to ARM chip, and the equipment that operate is selected and confirmed.If do not think, operation can be to the movable memory equipment of selecting by cancel button, and ARM chip is received after instruction, removes the control to this movable memory equipment, and after being unloaded, user can pull out safely.

3. after clicking and confirming, ARM chip reads the file in the equipment that corresponding USB interface connects, and information exchange is crossed to screen display out, and user selects file by button control cursor.

4. choose after the file that will operate, press ACK button, send confirmation to ARM chip, screen display goes out actions menu.

5. select the content of operation in actions menu, as copy this file to inserting in certain file of another movable memory equipment in this device, press ACK button, ARM chip obtains instruction, find the destination address in another movable memory equipment, start to carry out replicate run, with seasonal screen display transmission progress bar.Now can cancel by cancel button.

6. after data transmission completes, screen display prompting message, user can continue alternative document to operate afterwards, also can finish the operation to this movable memory equipment by cancel button, and screen is got back to the interface that step 2 shows.

7. now can start again to operate from step 2, also can select to finish.

Two, only insert the situation (Fig. 3) of a movable memory equipment

1. movable memory equipment is inserted to a USB interface (1 in Fig. 1 or 2).

2.ARM chip detection, after movable memory equipment, sends information to display, and on-screen-display messages prompting user selects to want the equipment of service data, and user sends information by ACK button to ARM chip, and the equipment that operate is confirmed.If now do not think, operation can be by cancel button, and ARM chip is received after instruction, removes the control to this movable memory equipment, and after being unloaded, user can pull out safely.

5. the content of operation in choice menus, as move arrives alternative document folder in this movable memory equipment, presses ACK button, and ARM chip obtains instruction, finds destination address, starts to operate, with seasonal screen display transmission progress bar.Now can cancel by cancel button.

6. after having operated, screen ejects prompting, can continue afterwards other operations, also can finish the operation to this movable memory equipment by cancel button, and screen is got back to the interface that step 2 shows.

7. now can start again to operate from step 2, also can select to finish.

In sum, this device can be realized carrying out exchanges data between movable memory equipment and the data in single movable memory equipment being carried out to shirtsleeve operation.Due to its small volume and less weight, practical function, simple to operate, therefore can offer convenience for the data exchange in people's daily life.
