Description
Technical field
The present invention relates to a kind of method for interchanging data and device thereof, especially relate to method for interchanging data and device thereof between a kind of data-carrier store.
Background technology
Along with the progress of electronics technology and the prosperity of infotech, the application of data-carrier store more and more widely, the flash memory of various band USB interface, portable hard drive are the requisite data storage device that various electronic products are equipped with owing to volume is small and exquisite, easy to use, such as using in media products such as digital camera, MP3, MP4, game machine.There is a defective in the data-carrier store of existing band USB interface, be exactly data read, store must be by means of the computing machine that possesses data processing function, because these data storage terminals are memory storages of passive type, can't carry out data conversion storage between two data storeies.In use just there is this problem such as digital camera, the flash capacity of general digital camera or DC configuration is limited, during out on tours, a large amount of photographs or video dump on the portable hard drive if desired, just flash memory need be inserted computing machine, photograph or video be dumped on the jumbo hard disk by computing machine.If there is not computing machine, just can't carry out two exchanges data or unloadings between the data storer.
Summary of the invention
The technical problem to be solved in the present invention overcomes above defective exactly, proposes the DEU data exchange unit between a kind of data-carrier store, can directly carry out data transmission, storage between two data storeies, need not to assist by computing machine.
The present invention proposes the method for the exchanges data between a kind of data-carrier store simultaneously.
Technical matters of the present invention is solved by the following technical programs.
The characteristics of the DEU data exchange unit between this data-carrier store are: comprise microprocessor; First USB interface that is connected with microprocessor, second USB interface and the battery of power supply is provided for electronic component; Described first USB interface is a Data Input Interface, and described second usb circuit is a data output interface.
Also comprise the buffer memory that is connected with microprocessor.
Also comprise the display panel and the guidance panel that are connected with microprocessor.
Also comprise the flash memory or the built-in hard disk that are connected with microprocessor, be used to store data from the input of first USB interface.
The characteristics of the method for interchanging data between this data-carrier store are may further comprise the steps: a) microprocessor detects the connection status of first USB interface and second USB interface; B) microprocessor detects the fileinfo with the first USB interface connection device, and with the fileinfo of the second USB interface connection device; C) the microprocessor output command is given the equipment that is connected with first USB interface, reads in its data, and output command is exported the data of reading in from first USB interface to the equipment that is connected with second USB interface to it.
In the described step c), microprocessor is stored in earlier in the buffer memory after reading in data, and reading of data is exported to the equipment that is connected with second USB interface from buffer memory again.
Microprocessor is also exported to work state information display panel and is shown.
Microprocessor is also accepted the data input of instruction control first USB interface of guidance panel and the data of second USB interface are exported.
In the described step c) microprocessor with the data storage of reading in flash memory or built-in hard disk.
The present invention is compared with the prior art the beneficial effect that is had: be provided with two USB interface, control by microprocessor, read in data from one of them USB interface, from another USB interface output data, microprocessor can be discerned the data-carrier store that is connected with USB interface, realizes the data transmission between two data storeies.Because volume is small and exquisite, easy to carry, just can realizes the copy of file by the simple key-press operation, thereby greatly make things convenient for the use of the data storage terminal of prior USB interface.
Description of drawings
Fig. 1 is the block diagram of the specific embodiment of the invention.
Embodiment
DEU data exchange unit between a kind of data-carrier store as shown in Figure 1 comprises microprocessor 3; First usb 1, second USB interface 2, buffer memory 4, display panel 5, guidance panel 6, hard disk 7 by microprocessor 3 controls; And the battery 8 that working power is provided for above-mentioned components and parts.
Has embedded software in the microprocessor 3, adopt (SuSE) Linux OS, be used for each hardware is managed, comprise driver, the power management routines of driver, demonstration and guidance panel interface of driver, the hard-disk interface of master routine that file reads and transmit, USB interface.
DEU data exchange unit between above-mentioned data-carrier store may further comprise the steps when working:
A) after the start, according to the instruction of user from guidance panel 6 inputs, System self-test, microprocessor 3 detects the connection status of first USB interface and second USB interface.
C) microprocessor 3 is according to the input instruction of guidance panel 6, with equipment that second USB interface 2 is connected in set up file directory.Microprocessor 3 output commands are given the equipment that is connected with first usb 1, read in its data, and will be stored in earlier in the buffer memory 4 after the data of reading in.
D) microprocessor 3 output commands are given the equipment that is connected with second USB interface, and reading of data is exported to the equipment that is connected with second USB interface from buffer memory.And the progress msg of data transmission exported to show its demonstration, and prompting user operation.
The user can pass through input command in above step c) and the step d), and the data that read are stored in the hard disk 7 simultaneously, perhaps data only can be stored in the hard disk 7 and not output to second USB interface 2.
